1 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
3 * dbxread.c, coffread.c: static-ize functions that were
4 gratuitiously external. (From Fred Fish.)
6 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
8 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
9 until it is large enough.
11 * dbxread.c (read_type): Handle error case slightly better.
12 Make complaint message not C++-specific.
14 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
16 * infrun.c (wait_for_inferior): Fix step/next so that you only
17 stop at the beginning of a new line. This fixes various problems
18 with for loops, nested if-else's and switch statements.
20 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
22 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
23 between symtabs and psymtabs become ordinary error()s.
25 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
26 properly, making "end pc" correct in shared lib psymtabs.
27 (From Guy Harris <guy@auspex.com>.)
29 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
31 * dbxread.c: Enable, but soften, const_vol_complaint.
32 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
33 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
34 should be file-scope, not global.
35 (read_struct_type): Remove ancient multiple-inheritance warning.
36 (read_range_type): Check base type, complain & patch if undefined.
37 * stack.c (frame_info): Demangle the function name in `info stack'.
40 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
42 * eval.c (evaluate_subexp_for_address): Don't use
43 TYPE_POINTER_TYPE directly (it might be zero if this type has
44 never had a pointer created before); use lookup_pointer_type.
45 * symtab.c (lookup_method_type): Arguments were swapped in all
46 callers, so fix it here. I'm amazed this worked at all!
48 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
50 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
51 "bss" rather than "data" symbols, but which still conflict.
54 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
55 * core.c (core_files_info): Shorten output.
56 * exec.c (exec_files_info): Ditto.
57 (build_section_table): Ignore zero-length sections.
58 * language.c, printcmd.c: Lint.
59 * language.h (get_frame_language): Declare.
60 * saber.suppress: update.
61 * stack.c (find_relative_frame): Remove complex code that was
62 #if 0'd, stick with simple code. Lint.
63 * saber.suppress: Update a bit.
64 * symfile.c (add_symbol_file_command): Add "?" to question.
65 * utils.c (parse_escape): Avoid \a due to bdead compilers.
66 * value.h: Declare typedef_print.
68 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
71 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
72 (Reported by Mark Peek <mark@imagen.com>.)
74 * solib.c (solib_map_sections): Relocate all sections, even
75 though only the text section's size is tracked. Mark ld_text
76 for eventual elimination as we generalize to N sections.
78 * infrun.c (wait_for_inferior): Don't check if the PC is in a
79 call_dummy if we were stopped by a random signal that is being
80 passed to the program. This produced wierd results when calling
81 functions in the inferior and signals (e.g. SIGALRM) were in use.
83 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
85 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
86 Bugfix from Paul Eggert <eggert@twinsun.com>.
87 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
88 * valprint.c (print_floating): Print 9 digits for IEEE floats.

101 * Makefile.in (VERSION): Set to 4.1.
102 * language.c (set_language_command): Print useful help message,
103 and restore the language string after giving help.
104 * valprint.c (typedef_print): Print typedef in C or M2.
105 * symtab.c (list_symbols): Use it.
106 * main.c (main): Avoid any output before (gdb) prompt when -q.
107 * language.c (set_language_command): Handle errors by restoring
108 the language string to its current state (fix from A. Beers).
109 * doc/gdbint.texinfo: Roll in information from README. Rearrange
110 "how to install" and "how to print the doc" stuff so it drops
112 * configure.in: Rename rtpc CPU to romp to match config.sub.
113 * README, WHATS.NEW, TODO: Update for gdb-4.1.
115 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
117 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
118 autoloading shared libs, copyright etc on GDB startup, clean up $_
119 and $__ index refs, set/show listsize and related updates to list
120 cmd. New host/target configs.
122 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
124 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
125 from main Makefile.in version definition
126 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
128 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
130 * doc/gdb.texinfo: merge new language-switching and lang-specific
133 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
135 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
136 compilers (which may lack stddef.h).
138 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
140 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
141 N_WARNING are the same except for the N_EXT bit, so just use their
142 values alone, rather than OR-ing them with N_EXT.
144 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
146 * mipsread.c (parse_lines): Deal with negative extended line
149 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
150 global symbol conflicts.
152 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
154 * .gdbinit: Move 'set complaints' to top, so it runs even in
155 case we aren't debugging GDB.
156 * language.c (_initialize_language): Fix type check and range
157 check documentation strings.
158 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
159 language.c can use it. (Though language.c should really not be
160 handling warnings/errors the way it does, FIXME.)
161 * symtab.c (lookup_primitive_type): const lint.
163 Bugfix from Peter Schauer:
164 * source.c (lines_to_list): Make signed, to avoid comparison
165 going unsigned and complaining that -3 is too high for 21 lines.
166 * stack.c (lines_to_list): Ditto.
168 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
170 * Makefile.in (HFILES): Add minimon.h.
171 (VERSION): Roll version number to 4.0.95.
172 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
173 New rules for building distributions. Normal distribution
174 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
175 one level up from here; it calls make-proto-gdb.dir to build a
176 directory `proto-gdb' which is an image of the release. The old
177 `gdb.tar.Z' rule still works too.
178 * config.sub, configure: Roll in latest from ..
180 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
182 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
183 new-target, and new-config chapters; fix minor typos; come closer
184 to usual GNU markup conventions for @file @samp @code @var.
186 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
188 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
189 * mipsread.c (parse_partial_symbols): Enter the name of all
190 structs/unions... into the psymtab so we can access them if the
191 symtab is not read in.
192 * mips-tdep.c: Remove some unneeded #includes.
193 * xconfig/dec3100: Add HAVE_STRSTR.
195 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
197 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
198 * c-exp.y, m2-exp.y: Lint.
199 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
200 * valprint.c (val_print_fields): Check for stub type.
201 * mipsread.c (_initialize_mipsread): Avoid using
202 builtin_type_void at initialize time.
203 (mipscoff_symfile_read): use it now.
205 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
207 Merge multiple-language support, and partial Modula-2 support,
208 from Andrew Beers <beers@cs.buffalo.edu>.
210 * i387-tdep.c: New file, consolidates most 80387 support,
211 and eliminates host dependency on double<->extended conversions.
212 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

226 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
227 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
228 #if 0 out its uses, though, since they set a dead value.
229 * coffread.c (end_symtab): Use allocate_symtab.
230 (process_coff_symbol): #if 0'd for functions and params as above.
231 (read_enum_type): Recognize Modula-2 BOOLEAN.
232 * symtab.c (add_param_to_type): #if 0'd function to add a
233 parameter type to a function type's field list.

241 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
242 breakpoint condition language-independently.
244 * parse.c: New file with the common code remains of expread.y.
245 * parser-defs.h: New file with common declarations from expread.y.

304 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
306 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
307 entries are enclosed herein. Not all of these changes
308 have been merged into the master GDB sources -- check the
309 ChangeLog above here for the merge log.
311 Mon Jun 3 17:05:45 EDT 1991
313 m2-exp.y Created. Tested outside of GDB for a few days. Proper
314 operators were added, C specific operators and tokens
315 removed. yylex() revamped to some extent. Still things
316 missing from the grammar, such as sets.
317 Tested for two weeks in GDB v3.5.
319 Tue Jun 11 17:23:48 EDT 1991
321 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
322 so they are built-in. Sort of a hack.
324 Fri Jun 14 12:53:51 EDT 1991
326 m2-exp.y Added range checking for numeric constants. Any numeric
327 constant is assumed to be of builtin type INTEGER unless:
328 (1) it is octal or hexadecimal, in which case it is a
329 CARDINAL; (2) it is too big to fit into an INTEGER, in
330 which case it is a CARDINAL.
331 eval.c Added simple range checking for +, -, and * on integers.
332 Doesn't work very well for *, since 6 * 1,000,000,000 =
333 1,705,032,704, which fails the simple test of result >=
334 first_operand, no matter in what order the operands are.
336 Tue Jun 18 14:11:30 EDT 1991
338 Broke the parser into parts, one containing the C grammar and the other
339 containing code to be shared by all of the grammars.
341 The following files no longer exist:
346 The following files were added:
348 c-exp.y (The C grammar)
349 m2-exp.y (The Modula-2 grammar)
350 parser-code.c (Code that is shared by the above grammar)
354 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
355 now necessary to use the Bison compiler compiler, since it
356 will generate function/variable prefixes other than yy.
358 Tue Jun 18 16:47:49 EDT 1991
360 symtab.[ch] Added the external variable working_lang, than holds the
361 value of the current working language.
362 Added the ennumerated type language_mode, with the values
363 language_auto and language_manual, the former meaning that
364 GDB sets working_lang as needed, and the latter meaning
365 that the value of working_lang is totally under user
367 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
368 REAL, BOOLEAN and CHAR. Also added the type codes
369 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
370 utils.c Added set_language_command and show_language_command to
371 implement the GDB support commands "set language" and
373 expression.h A number of identifiers were added to the type exp_opcode
374 to facilitate Modula-2 builtin functions, integer
375 division, and array indexing.
377 Wed Jun 19 13:25:58 EDT 1991
379 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
380 if the language specified by working_lang requires the use
381 of strict typing of expressions. Eventually, even this
382 will be able to be changed by the user.
383 Added the macro RANGE_CHECK, which evaluates to non-zero
384 if the language specified by working_lang requires the
385 checking of a value against the domain of its type.
386 Eventually, even this will be able to be changed by the
388 language.[ch] Predicates involving types (simple_type, ordered_type,
389 same_type, integral_type, numeric_type, character_type,
390 boolean_type, float_type) are added. These predicates are
391 based on the current value of working_lang, and are handy
394 Wed Jun 19 15:39:34 EDT 1991
396 eval.c Added the function type_array_rank which computes the rank
398 valarith.c Added the funtion value_bool, which when given a integer
399 value.h value (ie. struct value *) as an argument, it returns a
400 boolean value (ie. struct value *) true if that integer
401 is non-zero, and a boolean value false otherwise.
402 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
403 will print out properly.
405 Wed Jun 19 16:36:34 EDT 1991
407 valops.c Added the function value_capitalize, which returns it
408 value.h argument capitalized if its argument is a lowercase
409 letter, or the argument unchanged if its argument is not a
411 valarith.c Added the function range_check_p, which returns non-zero
412 value.h if its value argument is between the integral bounds upper
414 Added the function range_check_enum_p, which makes sure
415 that its value argument is a valid member of the domain of
417 Added the function range_check_range_p, which makes sure
418 its value argument lies between the upper and lower bounds
419 of its type argument, which must be a ranged type.
420 Added the function check_array_index, which range and type
421 checks an index of an array.
422 Added the function value_multi_subscript, which computes
423 array[idx1,idx2...idxN], given a value array and an array
424 of values representing indicies.
425 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
426 unpack_long to work with TYPE_CODE_BOOL and
429 Wed Jun 19 18:04:08 EDT 1991
431 symtab.c Stored pervasive types in a structure and make
432 lookup_pervasive_type() a lookup function that was based
433 on working_lang. If lookup_pervasive_type() returned
434 non-zero, then that value was returned (a fix, since
435 before it simply wouldn't return the pervasive type.)
436 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
437 non-zero if the language specified by working_lang means
438 "conversion" when it says "cast".
439 valops.c Added the function value_real_cast(), which performs a
440 value.h *cast*, not a *conversion*, which is what value_cast()
441 does when it can. In particular,
442 value_cast(<float_type>,4) = 4.0, while
443 value_real_cast(<float_type>,4) = some mess.
444 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
445 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
446 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
447 and MIN on integral types. *NOTE*: These are currently
448 hardcoded to work only if there are 8 bits per storage
450 eval.c Made logical functions call value_bool to return a
451 properly typed boolean value, based on working_lang.
453 Thu Jun 20 11:55:27 EDT 1991
455 valprint.c Types now print out in a Modula-2 fashion. This works for
456 the cases when the type is printed out step-by-step, that
457 is, it doesn't work when the name of a structured type
458 (which includes the keyword "struct", etc.) is simply
460 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
461 since type specifications in C and Modula-2 are very
462 different. The C printing of a type is very recursive,
463 whereas in Modula-2 it is generally very simple. C has
464 type prefixes and suffixes, which have no real analogue in
465 Modula-2. Maybe type_print() should call a language
466 specific type printer. This is also advantageous if we
467 compile GDB to exclude some of the languages. We'll just
468 leave those functions out.
470 Thu Jun 20 16:57:10 EDT 1991
472 dbxread.c When reading the complete symbol table in (via
473 psymtab_to_symtab()), the number and types of function
474 arguments are added to a function type. define_symbol()
475 calls add_param_to_type() to accomplish this.
476 Assumption: when we come across a function definition
477 (N_FUN symbol with an 'f' or 'F' in the name), its
478 arguments will appear before another function definition.
479 When a function is found, a pointer to its type is placed
480 in the global in_function_type. Changes that
481 add_param_to_type() makes are to this global.
482 valprint.c The type of a function now includes (for Modula-2) the
483 types of its parameters.
484 eval.c Type checking and a check for the proper number of
485 arguments is now done for function calls. Not sure of the
486 impact this has on C++ member function yet.
488 Thu Jun 20 19:58:48 EDT 1991
490 valprint.c Rewrote the type printer. Broke it into two language
491 specific parts, adding the functions type_print_m2() and
493 An unfortunate consequence is this: if you debugging a C
494 program in Modula-2 mode (why?), info types does not work
495 well with regular expressions, since the types are printed
496 out in Modula-2 terminology, but stored in C terminology.
497 language.[ch] Added the functions new_type_last(), type_keyword(), and
498 type_sep() to aid in the printing of typedefs.
499 symtab.c Made the printing of typedefs as language independent as
500 possible through calls to new_type_last(), type_keyword(),
503 Fri Jun 21 11:50:26 EDT 1991
505 dbxread.c Check all incoming ennumerated types. If it looks like
506 Modula-2's BOOLEAN type, then change the type_code of the
507 type to TYPE_CODE_BOOL so we can process it as a boolean
509 valprint.c Replaced some of the 0x%x with calls to sprintf and
510 hexformat() in val_print().
511 language.[ch] Added the function hex_to_string(), which converts its
512 integral argument to a hexadecimal number (format is
513 language based) and returns the result as a string.
515 Mon Jun 24 12:25:07 EDT 1991
517 valprint.c Some functions call type_print_1() directly, instead of
518 value.h using type_print(), so they can specify where (column) to
519 print things. Since type_print() takes care of language
520 dependence, that needs to be called first. Added a
521 parameter depth to type_print() (so it is now like
522 type_print_1). Changed type_print to type_print_at, and
523 made type_print a macro that passes a depth argument of
525 symmisc.c Changed all calls to type_print_1 to calls to
527 Makefile.dist Made it possible to build GDB for a specific set of
528 depend languages. Do this by passing a definition for the macro
529 LANGS to make. LANGS should be a string containing a
530 space-separated list of language names (ie. LANGS="c m2").
531 The default is to build all languages. Note that grammar
532 files must follow the naming convention of <lang>-exp.y.
533 gdb.lang This holds the current value of the LANGS macro. It is
534 examined every time make is called, and is updated if
536 eval.c Added #ifdef _LANG_<lang> to these files.
537 expread.c Still need to add them to dbxread.c and coffread.c.
545 Mon Jun 24 16:33:11 EDT 1991
547 language.[ch] Added the functions hexformat_pre() and
548 hex_to_string_pre(), which take a prefix argument to
549 include in the format string. Thus, hexformat_pre("08") will
550 return "0x08x" (if the working language is language_c).
551 Made hexformat() and hex_to_string() calls to the above
552 with "" as the prefix argument.
554 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
555 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
556 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
557 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
558 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
559 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
560 valprint.c, vax-pinsn.c
562 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
563 calls to hexformat() and hex_to_string(). Format strings without
564 the leading "0x" were ignored.
566 depend Updated to take the above into account.
569 Tue Jun 25 15:27:18 EDT 1991
571 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
572 and type_check_t to keep track of the current state of
573 range and type checking.
574 main.c Added the variables range_mode, range_check, type_mode,
575 and type_check to record the current state of range and
576 type checking. Added initialization code to main().
577 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
581 Tue Jun 25 17:57:08 EDT 1991
583 dbxread.c process_one_symbol() updates the variable (enum language)
584 source_lang based on the extension of the filename
585 contained in the N_SO sybmol that started this symtab.
586 When end_symtab() is called, the value of source_lang is
587 put into the language field.
588 stack.c select_frame() sets working_lang (and possibly type_check
589 and range_check) to the language field of the symtab
590 associated with the frame that is selected if working_mode
591 is language_auto. If working_mode is language_manual, a
592 warning is printed and working_lang is not set.
593 language.c Added the function set_type_range(), which sets the value of
594 type_check and range_check (if their modes call for
595 automatic setting) based on the current value of
596 working_lang. A non-zero argument will cause the current
597 settings to be output.
600 Wed Jun 26 14:51:40 EDT 1991
602 eval.c Added range checks on assignment.
603 m2-exp.y Added the grammar for sets to the language. Currently,
604 these do not do anything except print an error message.
606 Wed Jun 26 17:01:04 EDT 1991
608 m2-exp.y Added the ability for parse_number() to parse negative
609 numbers. A global flag is set upon encountering a unary
610 minus. This was done to make, for example, 1 parse as a
611 CARDINAL, and not as an integer, per Wirth's examples in
612 Programming in Modula-2 ed.4.
613 valprint.c Added support for "set radix 2" by then setting
614 output_format to 't'.
615 eval.c Implemented range checking on subrange types. Added calls
616 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
617 Implemented MIN and MAX for ennumerated types. The
618 minimum value of an ennumerated type is defined by Wirth
619 as the first identifier, and the maximum as the last.
620 m2-exp.y Made octal numbers ending with "B" be characters and those
621 ending with "C" be numbers, per Wirth's book. (p. 34)
623 Thu Jun 27 14:11:52 EDT 1991
625 stack.c select_frame() now only sets working_lang, it does not
626 notify the user. If working_mode is language_manual, then
627 a warning is issued once.
628 main.c At the end of each call to execute_command(), working_lang
629 is checked against the local static (enum language)
630 current. If they differ and working_mode is
631 language_auto, the new settings of language, type and
632 range checking are printed out.
633 stack.c Modified frame_info() to include the language of the
634 current frame in the output of "info frame".
635 language.[ch] Added the function language_str() which returns the name
636 of the current language.
638 Fri Jun 28 15:33:14 EDT 1991
640 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
641 the language. INCL and DECL currently cause an error,
642 since sets are not implemented yet. INC and DEC are
643 implemented as PREINCREMENT/PREDECREMENT with one
644 argument, and as ASSIGN_MODIFY with two arguments.
645 eval.c Added type checking to the above cases.
646 value.h Added not_lval_constant to the lval_type ennumerated type.
647 not_lval_constant means that the value is a constant
648 value; that is 3 or 'a' or TRUE, not as in a constant
649 identifier. This is used to help coerce numbers such as 3
650 to either signed or unsigned numbers.
651 valops.c Added the function value_coerce_constants() which coerces
652 constant integers as following: if one is a constant and
653 the other is not, the constant's type is set to the type
654 of the other argument. If both are constants and one is
655 signed, the other is converted to a signed constant.
657 Sat Jun 29 17:26:29 EDT 1991
659 valarith.c Added a better range checker. It now checks range
660 (successfully) on integral operations [+-] (signed and
661 unsigned) for any C sized type. Still does not work well
663 int_in_size() returns an integer that is coerced to fit into
664 specified number of bytes.
666 Mon Jul 1 13:04:14 EDT 1991
668 language.[ch] Added the function binop_result_type(), which returns the
669 builtin (struct type *) type that would be the result of a
670 binop on the two values V1 and V2.
672 Wed Jul 3 19:22:53 EDT 1991
674 source.c Extended source_info() to include the source language in
675 the output from "info source".
677 Fri Jul 5 13:48:52 EDT 1991
679 utils.c Moved the support functions for the GDB set/show commands
680 dealing with language into language.c.
681 language.c Added the function language_info(), which displays info
682 about the current working language, type and range check
683 settings. Called via the GDB command "info language".
684 Added an initialization routine _initialize_language(),
685 that sets defaults for the language, type and range
686 variables and sets up the new GDB commands.
687 main.c Language setup moved to language.c.
690 Mon Jul 8 10:10:22 EDT 1991
692 valarith.c Debugged the range checker for arithmetic. Still does not
693 work for multiplication very well.
695 Mon Jul 8 12:40:37 EDT 1991
697 language.[ch] Added the function value_true() which returns non-zero if
698 its argument represents a boolean true value.
699 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
700 check the truth of an expression.
702 Thu Jul 11 12:51:34 EDT 1991
704 language.[ch] Added the predicate structured_type(), which returns
705 non-zero if the argument is a structured type.
706 Added the predicate pointer_type(), which returns non-zero
707 if the argument is a pointer type.
708 eval.c Added the ability to do addition and substraction on
709 pointers and integers. This case simply bypasses the
712 Thu Jul 11 14:41:42 EDT 1991
715 Added the symbol N_DEFD (0x4a) which is a definition
716 module dependency that is used by the GNU Modula-2
717 compiler and the linker. It is not important to GDB,
718 except that [dbx|coff|mips]read.c should ignore these
721 Fri Jul 12 16:07:00 EDT 1991
723 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
724 0 in val_print(). Also added statements to the else part
725 to coerce type (argument to val_print) to a pointer type
726 if it is an "array of unspecified length".
727 valops.c Added the function value_m2_string(), which returns a
728 (value) value which is a constant string, whose type is
729 (ARRAY [0..n] OF CHAR). The length field of the type
730 structure is set to zero, so it will be interpreted as an
731 "array of unspecified length".
732 stack.c Moved the language/frame mismatch check to
733 main.c:execute_command().
734 main.c The working language is recorded each time
735 execute_command() is executed. If working lang has
736 changed during its execution, then the new
737 language/type/range info is printed out for the user. If
738 the working language does not match the language of the
739 frame, a warning is issued.
741 Sat Jul 13 16:16:39 EDT 1991
743 eval.c Moved all the type-checking stuff for operators to
744 language.[ch] language.c. This is so we can keep language-specific
745 stuff (like for what type operators are defined) in
747 language.[ch] Added the function binop_type_check(), which checks to see
748 if its two (value) arguments are type-compatible with its
749 opcode argument. The opcode should represent an operation
750 involving an operator. Also added the macro function
751 unop_type_check, which calls binop_type_check with a
752 NULL second argument.
753 expprint.c Added Modula-2 operators to the op_print_tab, so info
754 expression.h break works correctly. Also added "op_string", which
755 returns the string corresponding to the (enum exp_opcode)
756 opcode that is its argument.
759 Sat Jul 13 18:26:18 EDT 1991
761 coffread.c Added code to record the type of function arguments with
762 each paricular function. Code is very similar to that
764 dbxread.c Moved add_param_to_type() to symtab.c
765 symtab.[ch] Added function add_param_to_type() from dbxread.c
767 *** NOTE: The above additions have not been tested.
769 Mon Jul 15 12:50:47 EDT 1991
771 langauge.[ch] Added the functions type_error and range_error, which work
772 like error() except if the type/range mode is set to
773 *_mode_warn, then they do not do a return_to_top_level(),
774 but merely print a warning.
775 Also changed [set|show]_[type|range]_command() to support
776 the new "warn" feature.
778 Thu Jul 18 17:50:54 EDT 1991
780 mipsread.c Added code to record the type of function arguments with
781 each particular function. Code is very similar to that
784 *** NOTE: The above additions have not been tested.
786 Fri Jul 19 11:19:10 EDT 1991
788 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
789 UMIN_OF_SIZE, which when given a size of a numeric type,
790 return the maximum and minimum value it can hold. UMAX...
791 and UMIN... return the result for unsigned types.
792 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
793 struct types. They call above macros.
794 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
795 avoid a name conlict with the above.
796 c-exp.y Added range checking on numeric constants in
797 parse_number() for completeness.
798 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
799 return 0 if working_lang is not language_c.
801 Thu Aug 8 14:17:22 EDT 1991
805 breakpoint.c Documentation strings of some commands changed to
806 eliminate the references to the C language where
809 Tue Aug 13 15:48:03 EDT 1991
811 m2-exp.y Added qualified identifiers to the grammar. The semantics
812 are slightly different from those of the GDB operator ::
814 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
815 type_exp, where type_exp is any valid type expression.
817 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
818 printcmd.c Modified ptype_command() so it actually parses the input
819 (necessary for type expressions with scope qualifiers).
820 Added the function ptype_eval() which expects an
821 expression composed of one OP_TYPE element.
822 *.[ch] Replaced all occurences of parse_c_expression with
824 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
826 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
828 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
830 Small fixes from Peter Schauer:
832 * infrun.c (child_attach): Lint.
833 * solib.c (find_solib): Handle shared libs version 2.
835 Small fixes from David Wood:
837 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
841 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
842 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
844 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
845 chars_per_line is at maximum (user typed `set width 0'). Fix
846 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
848 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
850 * coredep.c: include ptrace.h where necessary.
851 * mipsread.c(parse_lines): fix unsigned char problem that was
852 messing up line numbers on SGI's and possibly other MIPS based
854 * infrun.c (child_create_inferior): use better test to check
855 return val from setpgrp().
856 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
857 for sgi/irix support.
859 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
861 * mipsread.c (parse_symbol): Put non-static procedures
864 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
866 Patch together `text_start' and `text_end' for 29K port.
868 * exec.c (exec_command): If NEED_TEXT_START_END, define the
869 variables and set them based on the exec file.
870 * am29k-tdep.c: declare text_start.
871 * valops.c (call_function_by_hand): declare text_end.
873 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
874 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
875 because machines that do this will also have to know to
876 set NEED_TEXT_START_END. Besides, it was a redundant way to
878 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
879 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
882 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
884 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
886 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
887 Pass MUNCH_DEFINE to munch whenever we run it.
888 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
889 format string; use 0x%x instead.
890 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
891 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
892 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
893 * inflow.c: Handle `short' process group IDs.
894 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
895 and check for ptrace errors.
896 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
897 (coff_symfile_init): Initialize text_bfd_scnum.
898 (read_coff_symtab): Use it to find the text [and absolute?] sections.
899 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
900 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
901 Merge target arm case with other "easy" cases. Add target
902 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
903 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
905 * minimon.h, remote-adapt.c, remote-mm.c: Add.
906 * munch: Cope with RT/PC putting fns in data segment.
907 Restore ability to override `nm' by specifying MUNCH_NM.
908 * xconfig/rtbsd, xconfig/ultra3: New host systems.
909 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
910 and remote-adapt. Remove encapsulated coff #define's (the
911 support should go in BFD, and gdb shouldn't know or care).
912 * tconfig/a29k-kern: Same, but for remote kernel debugging.
913 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
914 * tm-29k.h: Update BADMAG (though it should go away).
915 Allow the register definitions to be overridden in another
916 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
917 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
918 DUMMY_SAVE_GR96, for handling kernel calling conventions
919 that use GR64+ rather than GR96+.
920 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
921 remote debugging of Ultra3 kernel. Includes tm-29k.h and
922 overrides various things.
924 * remote-mm.c (mm_attach, mm_wait): Handle attach like
925 child_attach does, making a clean stop in the newly attached
929 * coffread.c: Make coffread independent of any particular
930 variant of COFF. Avoid #include-ing any particular one except
931 internalcoff.h. BFD now passes key values for symbol reading
932 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
933 and the symbol masks and shifts); use them.
934 Remove obsolete end_of_text_addr.
936 * exec.c: Remove unused include files.
938 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
940 * Makefile.in (documentation targets): Pass $(M4).
941 Bugfix from eggert@twinsun.com (Paul Eggert).
943 * stack.c (down_silently_command): Check for stack existence.
945 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
947 * Makefile.in (VERSION): Update to 4.0.3.
949 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
951 * core.c (core_file_command): Print frame at coredump with
952 its level number, by calling print_stack_frame.
953 * frame.h: Add selected_frame_level, print_stack_frame.
954 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
955 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
956 Change print_sel_frame and print_selected_frame callers to
959 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
960 * symfile.c (free_named_symtabs): Ditto.
961 * main.c (main): wrap_here needs an arg.
962 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
963 (solib_add): Avoid noise.
964 (solib_create_inferior_hook): Lint.
965 (sharedlibrary_command): Move dont_repeat to here.
966 * utils.c (error): Call wrap_here to force buffered output.
968 Small patches from Peter Schauer:
970 * coffread.c (start_symtab): Free any existing line_vector before
972 (read_coff_symtab): Ditto for type_vector.
974 * source.c (lines_to_list): New variable, replacing function.
975 (all uses): Use as variable.
976 (_initialize_source): Add 'set listsize' and 'show listsize'.
977 * utils.c (lines_to_list): Remove function.
978 * stack.c (print_frame_info): Use as variable.
979 * defs.h (lines_to_list): Remove declaration.
981 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
983 * breakpoint.c (insert_breakpoints): Restore warning about
984 the program might be running in another process, but only for
985 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
986 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
988 * utils.c (error): if error_pre_print is set, print the string
990 * main.c (main, print_gnu_advertisement, print_gdb_version):
991 Reformat legalese so it always prints, but acts as an "I'm here"
992 message while symbols are being read. If any errors occur,
993 print a few newlines to set off the message and start it at the
994 left margin. Remove mention of "help" command, and don't yak
995 about symbol reading.
996 (catch_errors): Error string is now printed first in case of
998 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
999 suggest the "help" command.
1001 * Makefile.in (VERSION): Set to 4.0.2.
1003 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1005 * .gdbinit: Remove useless "rr" command. Set complaints
1006 to 1 for people debugging gdb.
1008 * breakpoint.c, remote-vx.c: Reword strings printed by
1009 catch_errors callers.
1011 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1013 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1014 (Fix from kenc@viewlogic.com.)
1016 Fix some infrastructure to be able to cope with host and target
1017 machines with different sized basic types (ints, ptrs, etc).
1018 (Idea from pierre@la.tce.com (Pierre Willard).)
1020 * values.c (value_from_longest): Rename from value_from_long.
1021 Handle pointer types as well as integers, so that targets with
1022 different pointer sizes from the host can be accomodated.
1023 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1024 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1025 uses of value_from_long to value_from_longest.
1026 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1027 the correct pointer type to value_from_long{est}.
1029 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1031 * remote-vx.c: Remove obsolete code for calling functions via
1032 vxworks kludge interface (it referenced value_from_long).
1034 * valops.c (value_string): Find malloc with lookup_misc_func, not
1037 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1039 Make writing to files work properly. (Fixes to BFD are also needed.)
1041 * core.c (core_open): Open file ourselves, read or r/w, depending on
1042 write_files. Use bfd_fdopenr.
1043 * gdbcore.h (write_files): New variable.
1044 * exec.c (write_files): Define variable, add set&show for it.
1045 (exec_file_command): Use write_files to open for read or r/write.
1047 Make shared library reading happen automatically. These changes
1048 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1050 * inferior.h (stop_soon_quietly): Add to exported variables.
1051 * infrun.c (child_create_inferior): call solib hook, if defined.
1052 (child_attach): call solib hook, if defined.
1053 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1054 (find_solib): Use lookup_misc_func rather than hand-rolled.
1055 (symbol_add_stub): New stub for catch_errors.
1056 (solib_add): Avoid output if !from_tty. Catch errors rather
1057 than just calling symbol_file_add and bombing.
1058 (solib_create_inferior_hook): Interface with the target process
1059 to let it read and alloc shared libs, then figure out what it did.
1061 * core.c (validate_files): Fix typo, soften warning.
1062 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1064 * utils.c (fputs_demangled): Avoid duplicate printing if
1065 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1067 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1068 (Fix from pierre@la.tce.com (Pierre Willard).)
1070 * main.c (catch_errors): Change argument to a char * from an int,
1071 since a char * can point to a struct full of glop, but an int
1072 is not guaranteed to be able to hold a pointer.
1073 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1074 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1075 * core.c (core_open, solib_add_stub): Adapt.
1076 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1078 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1080 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1081 by adding .NOEXPORT target.
1083 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1087 * Makefile.in (VERSION): Roll to 4.0.
1088 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1090 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1092 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1095 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1098 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1100 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1101 reflect above name change
1103 * WHATS.NEW: correct pointer to refcard.
1105 * doc/gdb.texinfo: update New Features, Installing
1107 * doc/gdbint.texinfo: add short description of configure +template
1109 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1111 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1113 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1115 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1116 tar file, add dependencies for referenced doc files.
1118 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1120 * coffread.c, symfile.c, stack.c: saberized.
1122 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1124 * doc/refcard.tex: permuted Essential Commands sec
1126 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1128 set/show symbol-reloading
1129 default set complaints 0
1131 RET-repeat disabled after prompted long displays
1132 processID (attach) interpretation of 2nd GDB cmdline arg
1134 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1136 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1137 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1138 breakpoint.c, main.c: lint.
1140 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1142 Install new configuration scheme for GDB and friends.
1144 * config.sub: Translate ordinary names to three-part names.
1145 * configure: Use three-part names internally.
1146 * configure.in: Translate three-part names to filenames.
1148 * README, WHATS.NEW: Update for gdb-4.0.
1149 * Makefile.in: Roll VERSION to 3.99.
1151 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1154 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1155 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1156 to single structures rather than arrays; when passing
1157 their address, use &. This avoids trouble with bdead compilers.
1158 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1159 instead. This avoids portability headaches.
1160 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1162 * source.c (open_source_file): Avoid ANSI const bdeath by
1163 skipping declaration and then casting result value.
1164 * tm-hp300bsd.h: Clarify comment.
1165 * utils.c (strstr): Result is const char *; ANSI bdeath.
1166 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1167 since system include file defines it differently from "defs.h",
1168 though the two are equivalent for our purposes.
1169 * tconfig/hp300bsd: Add m68k-tdep.o.
1171 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1173 * tconfig/sun*4: Remove warnings about system assembler.
1175 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1177 * mcheck.c: Avoid warning about undeclared abort fn.
1178 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1179 it causes recursive calls to error() when used in cleanups.
1180 To do so requires that we make it a function, so we do.
1181 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1182 * utils.c (do_cleanups): Remove the current cleanup from the
1183 chain *before* calling it, in case error() is called from it.
1184 The result won't be pretty, but won't be an infinite loop either.
1186 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1188 * dbxread.c (read_struct_type): Grok anon structs for C++.
1189 (vb_name, vptr_name): Null terminate these strings.
1191 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1193 Minor bug fixes from BSD Net2 gdb:
1195 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1196 returns 0, there is no previous frame.
1197 * breakpoint.c (commands_command): If !from_tty, don't call
1198 input_from_terminal_p().
1199 * dbxread.c (record_misc_function): Speed up slightly.
1200 (compare_psymbols): Ditto.
1201 * infcmd.c (do_registers_info): Take a second argument to
1202 determine whether to print float registers. "info registers"
1203 does not do so anymore. "info all-registers" does, now.
1204 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1206 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1207 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1211 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1212 executing_breakpoint_commands if we are interrupted by error.
1213 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1214 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1215 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1216 catch_errors() so we can setup the frame regardless of whether
1217 the shared libs work.
1218 * ieee-float.c (double_to_ieee_extended): Get exponent from
1219 right place in little-endian systems. From John Carey.
1221 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1223 * main.c: Remove unused terminating_signals and catch_termination().
1224 (long_options): Terminate with a zero element.
1225 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1226 (gdb_readline): Make call-compatible with readline.
1227 (init_signals): Improve comments re vfork vs. signal.
1229 * utils.c (prompt_for_continue): Use new gdb_readline().
1230 If we prompt for continuation, we don't let CR repeat the previous
1231 command, once we get back to a prompt. It's too easy to keep
1232 hitting CR, expecting "--more--" prompts, and have some long
1233 command start repeating on you.
1235 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1237 * blockframe.c (frameless_look_for_prologue): Speed up by
1238 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1239 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1240 Define two variants, one faster.
1241 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1242 and return zero, rather than giving an error.
1243 (setup_arbitrary_frame): Initialize the PC in the new frame.
1244 (skip_prologue): Add a second arg saying whether we're just
1245 checking for a frameless function or not.
1247 * core.c (core_open, core_close, core_xfer_memory): Move
1248 section table pointers and bfd* into the target_ops.
1249 (core_open): Allow errors in shared lib reading, etc.
1250 (core_files_info): Describe shared library sections.
1252 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1253 exec_files_info, set_section_command): Move section table
1254 pointers and bfd* into the target_ops.
1255 (add_to_section_table): Add BFD to section table.
1257 * target.c (target_xfer_memory, target_info): Pass target to
1258 xfer_memory and target_info functions.
1261 * gdbcore.h: Move struct section_table.
1262 * target.h: New home of struct section_table.
1264 * solib.c (solib_add): New argument is the target_ops whose
1265 section list is to be added to, if any. Reallocate the
1266 sections in that target to add any that come from shared libs.
1267 (throughout) so_sections renamed to sections.
1268 (solib_xfer_memory): Deleted.
1269 * tm-sunos.h (SOLIB_ADD): Add target argument.
1270 (SOLIB_XFER_MEMORY): Delete.
1272 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1273 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1274 from target_ops. It's the same on all targets. Add two section
1275 pointers to target_ops.
1277 * stack.c (find_relative_frame): Dump ancient algorithm for
1278 "down", just use handy "next" pointers.
1279 (frame_command): Don't error if there is no stack; let user
1282 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1283 modifies static state in the parent process; new_tty itself
1284 runs in the child and modifies the child's file descriptors
1285 to match the saved static state.
1286 * infrun.c (child_create_inferior): Call new_tty_prefork,
1289 * infptrace.c (child_xfer_memory): Add ignored target arg.
1290 * remote-eb.c (eb_xfer_inferior_memory): ''
1291 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1292 * remote-vx.c (vx_xfer_memory): ''
1293 * remote.c (remote_xfer_memory): ''. Rename from
1294 remote_xfer_inferior_memory.
1296 * main.c (main): Only try to attach "corefile" argument if
1297 it starts with a digit.
1299 * symfile.c (symbol_reloading): New "set/show" variable.
1300 (symbol_file_add): Shorten message about symbol reading.
1301 (add_symbol_file_command): Merge with add_syms_addr_command,
1302 since this should work on all targets now.
1303 (stop_whining): Default to zero, to shut up complaints
1304 about bad symbol tables on many systems.
1305 (free_named_symtabs): Just exit unless symbol_reloading.
1307 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1308 and add comment explaining shared library screw.
1310 * source.c: #if defined => #ifdef.
1312 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1314 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1316 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1318 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1319 (doc/Makefile knows how to make one for local config)
1321 * Makefile.in: use doc/Makefile for doc targets
1323 * doc/Makefile: GDB documentation now has its own Makefile
1324 doc/refcard.tex: renamed from "gdbrc.tex"
1325 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1326 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1329 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1331 * values.c (baseclass_addr): When reading target memory, use the
1332 length of the basetype, not the upper type. We've only malloc'd
1333 enough space for the basetype, leading to errors in free().
1335 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1336 ends up as a function specially, since we know the actual type of
1337 the pointed-to address. This (somewhat) fixes display of
1338 expressions that include misc_function_vector names. Try `cond 1
1339 !strcmp("a","b")' then `i b'.
1341 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1342 The child can be proceeded from inside wait_for_inferior in
1343 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1344 getting skipped in that case.
1346 * expprint.c (print_subexp): Use filtered output, since the
1347 subroutines we call use it, otherwise the output is horribly
1348 mangled, since output of wrappable stuff comes out late.
1350 * Makefile.in: Bump VERSION to 3.98.1
1352 * infrun.c (child_create_process): Use execlp to find the
1353 shell to exec our target program. This requires some fiddling
1354 with `environ' since there is no execlpe().
1356 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1358 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1359 Minor rearrangement of refcard permits two new make targets--
1360 gdbrc.dvi DVI output for refcard, using CM fonts
1361 gdbrc.ps PostScript refcard, using PS fonts
1363 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1367 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1368 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1370 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1372 * doc/gdb.texinfo: last changes for release.
1373 Minor typo and formatting fixes; incorporated most fixes remaining from
1374 filed mail commenting on earlier drafts.
1376 Added warnings: pipes don't work in run command;
1377 conditions are converse of assertions;
1378 step over fn without debug info goes to next fn;
1379 vars may have "wrong" values near fn entrance, exit
1381 Added example from Kingston on printing repeated nonadjacent values
1383 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1384 shell mode for signals
1386 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1387 doesn't sound so much like its parent "Stopping and Continuing"; also
1388 moved entries on continue to top of section, so they don't get lost.
1390 Improved installation directions in appendix, added manual formatting
1393 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1395 * configure.in: Remove xm.h and tm.h even if we aren't linking
1396 new ones, so "./configure sun4; ./configure none" does the right
1397 thing. Assume that alldeps.mak and depend are already built in
1398 srcdir, and avoid running "make" (particularly "make depend",
1399 which involves "gcc") from inside configure. Build Makefile
1400 directly rather than building Makefile.conf first.
1401 * configure: Regenerate with above changes.
1402 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1403 to 3.98. Revise gdb.tar.Z procedure to produce a file
1404 called gdb-$(VERSION).tar.Z but which unpacks into a
1405 directory called "gdb". Move non-source files out of
1406 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1407 (depend): Don't try to do "gcc expread.y".
1408 (expread.o): Update dependencies by hand.
1410 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1413 Fixed a variety of small typos that prevented info from formatting
1414 cleanly; altered too-long heading for GPL Appendix, as discussed
1415 w/RMS; Changed date on cover to July 91.
1417 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1420 (1) Applied some fixes due to comments from Larry Breed (easier ones
1421 through chapsec 5.2)
1422 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1423 it's broken in latest texinfo
1424 (3) Introduced *some* use of [] for optional arguments, where
1425 explanation is not simpler by listing cmd w arg and cmd w/out arg
1426 separately. Still not using @deffn.
1427 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1428 couple of headings are too long. Need patches to texinfo or revision
1431 * Partial update to README (which still needs work for this
1432 release!): (1) use of configure corrected for new script,
1433 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1435 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1437 * symtab.c (lookup_symbol): Don't complain right off about
1438 no debug symbols; use the misc function vector first.
1439 (list_symbols): Use misc function vector to find symbols
1440 that don't have debug info, and print them.
1441 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1442 PC range doesn't match symtab PC range, as it does on the
1443 MIPS because our symtab reading isn't perfect.
1445 * dbxread.c (dbx_symfile_read): Make warning about
1446 "no debug symbols" slightly nicer.
1448 * source.c (select_source_symtab): If "main" symbol exists,
1449 but decode_line_spec can't find line info, don't just return
1450 a zero; try other source symtabs or give an error.
1452 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1453 their low addresses first, then rip through fixing high addrs.
1455 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1456 <runene@ifi.uio.no>.
1457 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1459 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1461 * Minor, mostly mechanical, cleanup of doc subdir for clean
1462 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1463 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1465 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1467 Mostly MIPS and general symbol-reading fixups.
1469 * doc/gdbint.texinfo: Add documentation on symbol-reading
1472 * mipsread.c: Remove kludges around #include "ecoff.h".
1473 Remove redefinitions of a_magic, etc, no longer used.
1474 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1475 Fix global overview comments to match symfile.c protocol.
1476 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1477 (mipscoff_symfile_read): Eliminate unused code. Avoid
1478 sorting all the symtabs, when all we have read here is psymtabs.
1479 The symtabs are sorted as they are created anyway. Tell
1480 condense_misc_bunches whether we're mainline.
1481 (psymtab_to_symtab_1): Pass filename when recursing, to make
1482 stack trace more informative.
1483 (parse_partial_symbols): Assume cur_hdr as argument.
1484 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1485 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1486 the TYPE_NAME of char *, since that's done in symfile.c.
1487 (free_numargs, parse_symbol, add_symbol, add_block,
1488 shrink_linetable): Declare these fns void.
1489 (upgrade_type): Convert tree of if's to switch. Clean up
1490 bogus "off == 0" handling with a complaint. Avoid setting
1491 field bitpos and bitsize of array with lower and upper bounds.
1492 Check specified bitsize of elements against their actual type's
1493 bitsize, and complain if different. Complain about unknown
1495 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1496 (psymtab_to_symtab_1): Print names of subsidiary files that
1497 are being read in. FIXME, we read far too many files. This code
1498 is not the problem, the problem is in parse_fdr where the psymtabs
1500 (cross_ref): Result should indicate that we used one aux entry
1501 normally, or two if we encountered a "next" entry. This used
1502 to leave the caller pointing at the wrong aux entry.
1503 (add_symbol): If overflowed cur_block, reallocate it larger,
1504 chase all pointers to it, and complain(), rather than clobber memory.
1505 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1506 (new_field): Only allocate one field initially, not two.
1507 Pull ++ out of macro argument. Simplify.
1508 (_initialize_mipsread): Avoid initialization of importd
1509 global_psymbols and static_psymbols.
1511 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1512 to properly set pst->symtab; avoid searching for it.
1513 (symfile_fns): Improve comments, add a FIXME.
1514 * dbxread.c: Update comments to reflect symfile protocol.
1515 (read_ofile_symtab, end_symtab): Return the symtab.
1516 (psymtab_to_symtab_1): Set pst->symtab.
1518 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1519 whether we're mainline.
1521 * symfile.h (sym_fns): Remove unused sym_discard member.
1522 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1524 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1525 the environment variable is not.
1526 * infcmd.c (finish_command): Use filtered printfs.
1527 * cplus-dem.c: Add struct tags to a few unnamed structs.
1528 * valops.c (value_coerce_array): Improve comments.
1529 * valprint.c (type_print_varspec_suffix): Print array size only
1530 if greater than zero.
1531 * m88k-tdep.c: Shift some lines left by one space, that had
1532 apparently been trashed at some point.
1533 * TODO: More things to do, a few got done.
1535 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1537 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1538 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1540 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1541 * expread.y, findvar.c, symmisc.c: Ditto.
1542 * printcmd.c (address_info): Update printed forms of LOC_
1543 symbols. Elim LOC_EXTERNAL.
1544 (print_frame_args): Keep track of param stack offsets before
1545 re-looking up to find the local register param is kept in.
1547 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1548 Further integration of mipsread into gdb. Eliminate unused
1549 routines, duplicate declarations. Handle static symbols in
1550 psymtabs as well as external symbols. When reading symtabs,
1551 insert symbols into the correct block (global, static, or a local
1553 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1555 (mipscoff_symfile_read): Don't call select_source_symtab.
1556 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1557 rather than SYMBOL_VALUE.
1558 (parse_external): Comment clobbering of top_stack.
1559 (parse_partial_symbols): Update comments. Allocate and parse
1560 static symbols as well as external symbols. FIXME, enum values
1561 are not handled in this pass, but should be. Inline new_psymbol.
1562 Use SYMBOL_VALUE_ADDRESS.
1563 (psymtab_to_symtab_1): Read symbols into global static block
1564 by default (until enter some function's local block context).
1565 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1566 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1568 * source.c (select_source_symtab): Select a source symtab
1569 from either the symtabs or, failing that, the psymtabs.
1570 (list_command): Update error message.
1571 (forward_search_command, reverse_search_command): Use getc, not
1572 fgetc, for speed. FIXME, add comment about buffers that die if
1573 overrun by long line.
1575 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1576 by an entire word, which is not portable, if we have a 32-bit
1577 field. (Code in dbxread.c already turns such bitfields, if
1578 aligned, into ordinary ints, but fixing this will help for other
1579 symbol formats and for future changes.)
1580 * core.c (core_open): Handle ANSI const brain death.
1581 * utils.c (vprintf): Fix varargs typo.
1583 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1585 * findvar.c (find_var_value): Handle &function better.
1586 * TODO: Document work needed on &fn and &array.
1587 * printcmd.c (print_address_symbolic): New arg is the prefix
1588 to print if a name is printed.
1589 (print_address_demangle): Honor "set print address" now.
1590 Use new arg above to improve spacing of output.
1591 * valprint.c (val_print): When printing function pointers,
1592 print symbolic form too.
1593 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1595 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1597 * core.c (memory_error): Reword error msg to mislead less.
1599 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1601 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1602 parse_partial_symbols): Use newer BFD internals (external_filehdr
1603 and external_aouthdr), byte-swap the fields that we care about
1604 before using them, and make the file header data local to
1605 read_the_mips_symtab rather than global.
1607 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1609 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1610 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1612 * main.c (command_line_input): Flush stdout and stderr
1613 before every call to readline. This reportedly fixes a bug
1614 that comes up in Sys V running emacs-gdb and/or xxgdb,
1615 when stdin/out are pipes or sockets.
1617 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1619 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1620 Avoid declaring Makefile dependencies, because GNU Make stupidly
1621 tries to update it if we do.
1623 * coffread.c: Revise for minor changes to bfd internal coff
1626 * configure: If -template= is given a relative path, make it
1627 absolute before recurring in subdirectories.
1629 * configure, configure.in, Makefile.in: Install "configure" script
1630 as replacement for config.gdb.
1631 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1632 * README: Update for configure, mostly. FIXME.
1634 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1635 target config files that they are for the host. When the lines
1636 get copied into the Makefile, this makes it more obvious what's
1639 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1641 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1642 tabs, which end up in the disassembler output inadvertently.
1644 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1646 Make it compile cleanly in an ANSI GCC2 environment.
1648 * blockframe.c: <stdio.h>
1649 * cplus-dem.c: free takes a void *, ifdef __STDC__
1650 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1652 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1653 * stddef.h, stdlib.h: Remove these files.
1654 * symtab.c: Avoid declaring qsort, close.
1655 * symfile.c: Avoid declaring close.
1656 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1657 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1659 Assorted other changes.
1660 * dbxread.c: include "libaout.h", not "liba.out.h".
1661 * printcmd.c (print_frame_args): Set recurse properly for
1662 indentation of struct and array parameters.
1663 * valops.c (value_cast): Allow cast to void.
1664 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1665 single_step() in a target-independent fashion.
1666 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1667 set up to be ready to continue. This makes us target independent.
1668 * infptrace.c (child_resume): Remove call to single_step; now
1669 can single step a SPARC target of any kind.
1671 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1673 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1674 docn into separate sections---basically chapters, plus two loose
1675 pieces that can be configured to go in different places. This
1676 allows GNU m4 to preprocess the manual without coredumping.
1678 * Makefile.dist: tell TeX where to find texinfo.
1680 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1682 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1683 the new target "rdl-apps.texinfo" which captures the Makefile
1684 variable that records where to find the Readline libraries.
1686 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1688 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1689 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1690 * defs.h (const, volatile): Only define if not already defined.
1691 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1693 * README: Update for release 3.95.
1694 * config.gdb: Don't create readline dir in subdir builds.
1695 * main.c: Include with "..." form for non-system include files,
1696 so "gcc -MM" for "make depend" works.
1697 Include readline files with "...h" rather than <readline/...h>.
1698 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1700 * coffread.c: Undo minor damage done by Rich Pixley. Use
1701 different internal and external representations of COFF
1702 data structures. Use new BFD routines for swapping them in and
1704 * symfile.c (free_named_symtabs): Avoid freeing file names that
1705 are null or empty. Old i960 tools seem to produce files that
1706 claim to have empty names, causing each successive file read
1707 to blow away the previous one.
1708 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1709 Move deferred_stores to top of file, but don't separate its
1710 #define's from its variable. Add commentary.
1711 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1712 favor of keeping the (working) config.gdb. Move readline
1715 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1717 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1719 * infptrace.c (fetch_registers): no result, since now void.
1720 * tconfig/news: target depends on m68k-tdep too.
1722 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1724 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1727 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1728 applied various small fixes due to or inspired by RMS comments
1730 * doc/gdb.texinfo: finished using all RMS comments, save those for
1731 appendices on readline and cmd history (which are in other source
1734 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1736 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1737 chapter 9; (2) documented 'break' command's menu mode for
1738 overloaded names, in response to hgs problem report C++ p-31
1740 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1742 * doc/gdb.texinfo: (1) better introductory example; (2) more
1743 consistent use of @code, @samp, @file, @kbd throughout; small
1744 cleanups to first three nodes; (3) new "Contributors" node;
1745 (4) Appendix, Renamed Commands; (5) divert specialized startup
1746 instructions to "Targets" chapter for generic manuals, while
1747 leaving them up front for manuals specific to specialized
1748 environments; (6) apply fixes from RMS comments through chapter 4.
1750 * pretex.m4: modify explanatory text slightly (and redefine
1751 "regexp") to keep GNU m4 from complaining. (It still crashes
1752 later, but one step at a time...)
1754 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1756 * readline/readline.c (update_line): Avoid dereferencing a pointer
1757 before comparing it to its bounds. Saber caught this.
1758 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1759 and only set PC if tgetstr returned non-null. Saber caught this.
1761 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1763 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1764 stuff for config manual) here where it counts; updated
1765 to use new subdir structure (gdb/doc/).
1767 * Makefile: generated from above via
1771 * gdbint.texinfo: added instructions on generating gdb.info* files
1772 locally for release. These are ordinary info
1773 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1774 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1775 to generate these, so we distribute them already formatted.
1777 * gdb.texinfo: included full Info node and menu crud (as generated
1778 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1780 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1781 put in comments-for-future gdb.info target (one day makeinfo will
1784 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1786 * gdb.texinfo: Updated to include new or old undocumented
1787 commands, at least the following (perhaps some others I forgot to
1788 record): info f, info float, info path, info program, info s, info
1789 set, info source, info terminal, info types, info user, set/show
1791 Also covered all recent GDB command renames for v4.
1793 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1795 * mipsread.c: Rather than keeping count of how many symtabs
1796 and psymtabs we have, for sorting purposes, count them when
1797 we need to sort. This fixes bug in rereading of symbol tables.
1799 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1801 * infcmd.c: renamed "info path" to "show paths"

1812 Fix up "saber_gdb" to work again.
1813 * saber.suppress: Update.
1815 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1816 symtab.h, target.c, target.h: Lint.
1817 * core.c: setup and select frame after reading shared libs,
1818 else reading shared libs will clobber them. Lint.
1819 * utils.c (error): Force out any buffered wrap text.
1821 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1823 * remote.c: Remove decls of memory_insert_breakpoint
1824 and memory_remove_breakpoint, no longer used. (Suggestion of
1827 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1828 to make it easier to interface to "configure"'d libraries.
1830 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1832 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1833 aliases for set/show print.

1889 * coffread.c [TDESC]: Move setting of debug_info from
1890 coff_symfile_read to find_linenos and make it work with BFD.
1892 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1894 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1896 * utils.c (strsave): Make arg const char* not char*.
1898 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1922 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1923 (This still doesn't seem to make MIPS bkpts work.)

1925 (symbol_file_command, add_file_command): Remove, obsol.
1926 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1927 Wrap output appropriately.

1929 selected_frame rather than target_has_stack or coredumping.
1930 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1931 enums appropriately.
1933 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1935 * signame.c: Include defs.h and param.h.
1937 * cplus-dem.c: Include defs.h and param.h.
1938 Makefile.dist: Don't hack in the "param.h".
1939 param.h: Don't include defs.h.
1941 * expread.y: Use a union to deal with the fact that type_stack
1942 can have both ints and enum type_pieces in it.
1943 ({push,pop}_type_int): New functions.
1945 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1957 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1958 copying.awk, solib.c, inflow.c, symmisc.c
1959 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1960 Use {value_as,unpack}_pointer (added to values.c)
1961 not {value_as,unpack}_long on CORE_ADDR's.
1962 Use longest_to_int (added to defs.h) instead of cast to int.
1963 Remove from_tty arg to mod_path.
1964 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1965 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2448 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2450 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2451 for printing the float info is host-dependent, not
2452 target-dependent. FIXME.
2453 * i386-pinsn.c: Move #includes to top, remove useless ones.
2454 * i386-tdep.c: Don't bother including <.../reg.h> since we
2455 don't use it (and it doesn't exist on host systems).
2457 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2458 Convert negative numbers properly.
2459 (ieee_test): Make numbers really random; fix format arg.
2461 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2462 * core.c (core_detach): Unpush core_ops, which might not be on
2463 top. We used to just pop the top, which broke things. Don't
2464 need dont_repeat() any more.
2465 (core_file_command): Psst! Don't repeat it.
2466 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2467 * expprint.c (print_subexp): Avoid switch fallthru on
2468 BINOP_ASSIGN_MODIFY, so we can print += and such.
2469 * frame.h: Fix typo.
2470 * inflow.c (kill_command): After killing inferior, print our
2471 current frame in the core file, if we have one.
2472 (generic_mourn_inferior): When inferior dies, either select
2473 the current frame (in the new target, e.g. core file), or
2474 set both the current and selected frames to NULL.
2476 Changes from Peter Schauer.
2478 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2480 * Make all file names fit in 14 characters (sigh and damn!):
2481 mv hp300hpux-xdep.c hp300ux-xdep.c
2482 mv symmetry-xdep.c symm-xdep.c
2483 mv symmetry-tdep.c symm-tdep.c
2484 mv convex-opcode.h convx-opcode.h
2485 mv tm-vxworks960.h tm-vx960.h
2486 mv tm-vxworks68.h tm-vx68.h
2487 mv Makefile.srcdir Makefile.sdir
2488 mv gdb-int.texinfo gdbint.texinfo
2489 mv remote-sa.m68k.shar rem-m68k.shar
2490 mv remote-multi.shar rem-multi.shar
2491 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2492 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2493 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2496 * command.c (user_info_1, user_info): New command for listing
2497 the user-defined commands.
2499 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2501 * dbxread.c (really_free_pendings): Clear file_symbols
2502 and global_symbols after freeing them; otherwise, running
2503 this function twice (if it appears twice on the cleanup
2504 chain), we try to free things twice.
2506 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2507 based on text_addr (the address of text in core), not on addr (the
2508 offset between text in the .o file and in core). This change
2509 is from Peter Schauer.
2511 * main.c: Define ALL_CLEANUPS as a cast of zero.
2512 (return_to_top_level): Use it.
2513 (main): Do all cleanups after each command run as part
2514 of the gdb startup sequence. Also do all cleanups before
2515 entering the command loop, and every time we exit the command
2516 loop and reenter. Before, the cleanups from the startup sequence
2517 were being left undone until the first error!
2518 (command_loop): Rename do_nothing cleanup to command_loop_marker
2519 so we can see it easily when examining the cleanup chain.
2520 (init_signals): Add another do_nothing for signal handling.
2521 (quit_command): Only try to kill target if it has execution.
2522 Problems in the target stack got us into a state where
2523 inferior_pid was nonzero but none of the targets had execution.
2524 In this state you couldn't exit gdb.
2526 * dbxread.c: Two changes from Peter Schauer.
2527 (echo_command): Fflush output after an echo command.
2528 (show_history): Pass all args to cmd_show_list.
2530 * utils.c (init_malloc): Call mtrace to turn on tracing
2531 if the environment variable MALLOC_TRACE is set to a file name.
2532 * mtrace.c: Add source file which provides a log of every malloc,
2533 free, and realloc to a trace file.
2534 * mtrace.awk: Add source file which analyzes the trace file.
2535 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2536 (VERSION): Roll to 3.94.3.
2538 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2539 (check_duplicates): Don't bother with watchpoints.
2540 (set_raw_breakpoint): Comment about danger of this routine.
2541 (watch_command): Parse and eval all args before calling
2544 * solib.c (find_solib): Avoid error in referencing memory to
2545 see if any more shared libraries have been added. This is
2546 particularly useful if the target has terminated. Bug reported
2549 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2550 in bringing up 3.94.2 on the Sun-3.
2552 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2553 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2554 expression (in scope) before reenabling watchpoint.
2555 * signame.c (init_sigs): Add missing declaration of i, fix
2556 sys_siglist declaration.
2557 * source.c (list_command): Fixed range computation to use
2559 * stack.c (backtrace_command): Do not allow command if target has
2560 no stack, print informative error message.
2561 * target.c (target_command): Do not write into command line
2562 because this fails if the target command is used in a user defined
2563 command. [This change was enhanced by gnu to support any-
2564 unique-prefix matching on target names.]
2565 * valops.c (value_struct_elt): Avoid infinite loop on an
2566 erroneous attempt to print the member of function (try p main.p).
2568 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2570 * expread.y (name_no_typename): Avoid reduce/reduce errors
2571 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2572 Since the GDB parser really doesn't use name_no_typename in a
2573 name-only context, the parser can't tell the diff between
2574 names and numbers here. Avoid allowing a name_no_typename
2575 to be a NAME_OR_*INT to resolve the conflict.
2577 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2579 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2581 * valprint.c (val_print_fields): bitfield printing didn't handle
2582 byte order. Indirect through a few more fns to cope.
2584 * values.c (modify_field): also cope with byte order.
2586 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2588 Cleanup for release 3.94.2:
2590 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2591 include files. Roll version to 3.94.2.
2593 * coffread.c (init_stringtab): Read length into unsigned char
2594 array before swapping; don't assume 32-bit longs.
2596 * target.c (target_info): Don't bother with get_sym_file, just use
2597 the symfile global variable.
2598 * symtab.h, symfile.c (get_sym_file): Delete it.
2600 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2601 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2602 (read_type): Replace one more error() with complain().
2604 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2606 * i960-tdep.c: Fix copyright attribution.
2608 * config.gdb: Quote all backquotes in doublequotes. You can
2609 quote me on that. BSD 4.4 shell found this one.
2611 * infptrace.c (throughout): The third argument to ptrace is an
2614 * infrun.c (wait_for_inferior): When program has terminated, we
2615 have to call target_terminal_ours before we pop that target off
2616 the stack (e.g. before a call to target_kill or
2617 target_mourn_inferior). This fixes problem where a program
2618 terminates, then GDB stops for (tty output) and you have to type
2619 "fg" to the shell to resume it. FIXME: This code for what to
2620 do after termination really should be in normal_stop instead.
2622 * gdbcore.h (read_memory_check): Change declaration; it changed
2625 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2626 4.4 prereleases, this avoids a bug in their sgtty compatability
2628 * remote.c: Use terminal.h rather than hand-rolling the same.
2630 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2631 * utils.c (strsave, strstr): Fix arg types.
2632 * valprint.c (val_print): lint
2634 MIPS symbol table support from Per Bothner:
2636 * symfile.c (symtab_fns): Remove initializer table that needs to
2637 be hacked for each new symbol file format supported.
2638 (add_symtab_fns): New function, chains symbol table
2639 handlers into the global list.
2640 (symfile_init): Search this list.
2641 * symfile.h: Add next pointer, declare add_symtab_fns.
2642 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2643 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2645 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2646 symbol *). Thus, we no longer need the hack to trash
2647 pst->filename. Good, since that hack confused code in symfile.c!
2649 (reorder_symtabs, destroy_all_symtabs): Removed static
2650 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2651 Instead, the latter now uses a temporary array (stack-allocated
2652 from an obstack, and then freed).
2654 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2655 haven't been set in the outermost stBlock of a procedure. This was
2656 a problem with f77 binaries on Ultrix 4.?.
2658 (new_symtab, new_symbol, new_type): Continue changing code to use
2659 obstacks more and otherwise conform to dbxread internal style.
2660 Made the free_code of symtabs be free_linetable (as in dbxread)
2661 instead of free_contents. This implies memory leaks when reading
2662 a new symbol table, until the conversion is finished. Did change
2663 (struct symbol) and (struct type) to be allocated on the
2664 symbol_obstack. Blocks and blockvectors are among the things
2667 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2668 tested much, but it solved one problem (reported by Meissner), and
2669 cleans up some other things. The problem happened when an
2670 included file contains actual code (functions) and not just
2671 definitions. The mips coff is a little inconvenient there, since
2672 it may cause a procedure to be mapped to the wrong psymtab.
2674 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2675 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2676 this will need work for the new core paradigm.
2678 Opcode patches from the net:
2680 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2681 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2682 missing altogether - they are added here. From Bruce Bauman.
2683 * mips-opcode.h: The low mask for C0 instructions was too small.
2684 From Garrett Lau. I modified the fix to check the entire 32-bit
2687 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2690 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2692 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2694 * dbxread.c (read_type): Pointer subtraction (value_sub in
2695 valarith.c) sometimes failed because the types of the
2696 pointers being subtracted were not identical.
2697 These differed because dbxread.c was allocating pointer types
2698 using dbx_alloc_type+smash_to_pointer_type instead of
2699 lookup_pointer_type. I failed to find a justification for the
2700 former, so I changed it to use the latter. Similarly, I
2701 replaced smash_to_function_type by lookup_function_type,
2702 and smash_to_reference_type by lookup_reference_type.
2704 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2705 _initialize_mipsread): corresponding changes.
2707 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2709 * source.c (mod_path): Do tilde_expand on each component of the path,
2710 rather than on the (list of) paths as a whole.
2711 (print_source_lines): Set first_line_listed in addition to
2712 current_source_symtab and current_source_line. If the source was
2713 not findable, after a "dir" command to fix the problem,
2714 a "list" would get the wrong lines.
2716 While I was there... (gnu):
2718 * dbxread.c (read_type): Change error to complaint.
2720 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2722 First attempt at detailed understanding of symbol table memory alloc.
2724 * dbxread.c (dbx_symfile_read): Free our string table if we
2725 aren't the mainline. Free the "info" struct since we're done with
2727 (init_psymbol_list): Free any previously allocated psymbol lists.
2728 (): FIXME: Should realloc-down the psymbol lists when done reading
2729 the main symbol file?
2731 * symmisc.c (free_symtab): Free fullname field too.
2733 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2734 (REGISTER_ADDR): Make result type unsigned int.
2736 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2737 define REGEX must also define REGEX1 (its dependency).
2739 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2741 * tconfig/i960: No longer works, points you at vxworks960 or
2744 * xgdb.c, XGDB-README: Remove file. Users can get the much
2746 * Makefile.dist: Remove all trace of xgdb.
2748 * breakpoint.c (breakpoint_1): Pass demangle arg to
2749 print_address_symbolic.
2750 (clear_breakpoints): Remove unused function.
2751 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2752 (breakpoint_re_set): Use catch_errors to do them all anyway.
2754 * gdb-int.texinfo (Host versus Target): Add section on what is
2755 a "host" feature versus what is a "target" feature.
2757 * infcmd.c (path_command, path_info): Handle the PATH variable
2758 (object search path) as conveniently as the source search path.
2759 * environ.c (set_in_environ): Set some vars in GDB's environment,
2760 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2761 * source.c (mod_path): New function, from guts of
2762 directory_command, modifies a path. Used by path_command.
2763 (directory_command): Call it.
2764 * defs.h (strsave): Declare.
2766 * utils.c (sevenbit_strings): Add new printing option.
2767 (printchar): Use it.
2768 (strsave): Provide this handy helper routine.
2769 (set_width_command): Rename set_screen_width_command.
2770 (_initialize_utils): "set screen-width" => "set width";
2771 "set screen-height" => "set height"; add sevenbit-strings.
2773 * infcmd.c (do_registers_info): Print floating point registers
2774 in raw hex as well as float format, regardless of whether it is
2775 a "virtual" convertible register.
2776 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2777 regs as a double, just in case it's being used that way.
2778 * values.c (unpack_long): Comment on array/function coercion.
2779 (unpack_double): Argument is in target byte order now. For
2780 integer arguments, just call unpack_long and float the result.
2781 * m68k-tdep.c: include defs.h for "const" handling.
2782 * remote-nindy.c: Use ieee-float stuff.
2783 (nindy_fetch_registers): Unpack double regs to host double, then
2785 (nindy_store_registers): Pack extendeds to host double, flip
2786 around by misusing unpack_double, send as target double.
2788 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2789 zero, as when stopped at the first instruction of a process.
2791 * blockframe.c: Fix filename in comment (param.h => tm.h).
2792 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2793 * tm-68k.h: Fix typos.
2795 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2797 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2799 * coredep.c (fetch_core_registers): Pass end-address of register
2800 section to register_addr as expected. Don't call supply_register
2801 if we'd just pass it garbage.
2803 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2805 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2807 * target.c (push_target, target_info): Cast enums to int for < or
2810 * stack.c (print_frame_info): Identify source file & line
2811 even if we can't print it.
2813 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2815 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2817 Clean up IEEE floating point support.
2819 * ieee-float.h: New file.
2820 * ieee-float.c: Write real routines to convert between host
2821 doubles and various target IEEE extendeds.
2822 * m68k-xdep.c: Eliminate assembler code for extended floats.
2823 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2824 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2825 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2826 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2827 double_to_ieee_extended.
2828 * i960-tdep.c: Define ext_format_i960.
2829 * m68k-tdep.c: Define ext_format_68881.
2830 * sparc-tdep.c: Define ext_format_sparc, though unused.
2831 * Makefile.dist (HFILES): Add ieee-float.h.
2832 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2835 Obsolete the "coffstrip" program in favor of using BFD's strip.
2837 * nindy-share/coffstrip.c: Remove file.
2838 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2839 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2840 * tconfig/nindy960: Remove reference to coffstrip.o.
2842 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2844 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2846 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2847 * dbxread.c: Remove static symfile_bfd.
2848 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2850 * inftarg.c (child_detach): Pop the child_ops vector if the
2851 detach is successful.
2852 * remote-nindy.c (nindy_create_inferior): Don't push a new
2853 nindy_ops since nindy uses the same one for execution and memory
2855 * core.c (core_ops): Use child_attach and child_create_inferior
2856 rather than default attach and create_inferior functions.
2858 Handle floating point registers in core files.
2860 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2861 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2862 This version untested since BFD doesn't yet support sun3 core
2864 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2865 conventions. Fix comments and style. This version has not
2866 been compiled yet, since we have no HP inhouse.
2867 * core.c (get_core_registers): Look for two sections, ".reg"
2868 and ".reg2", and pass both to fetch_core_registers sequentially.
2870 Revise directory path yet again.
2872 * source.c (forget_cached_source_info): Not static any more.
2873 (init_source_path): New default source path is "$cdir:$cwd".
2874 (dir_command): Handle variable arguments ($cdir, $cwd).
2875 (source_info): Print "Compilation directory" rather than
2876 "Originally compiled in" to remind people of $cdir.
2877 (openp): If the path contains $cwd, use current directory.
2878 (open_source_file): If compilation directory is known, replace
2879 first $cdir in path with the compilation directory.
2880 (print_source_lines): Even if we can't print the lines, set the
2881 current symtab and line for future commands like "info source" or
2882 "breakpoint". Also, error message now contains the file name,
2883 line number, and file access error message.
2884 (_initialize_source): Fix help text to describe changes.
2885 * main.c (cd_command): Forget cached source info when we chdir.
2886 * utils.c (strstr): Add simple implementation.
2888 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2890 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2891 Byte-swap COFF symbol tables if necessary when reading them in.
2892 Use complain() to replace error message in one spot. Needs
2893 corresponding change in bfd/coff-code.h to make some symbol
2894 swapping routines non-static.
2896 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2898 Merge changes from Eirik Fuller, for UTek.
2900 * defs.h (errno): Add declaration.
2901 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2902 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2903 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2904 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2905 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2906 declarations of errno.
2908 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2910 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2911 <rpc/rpc.h> and <rpc/types.h>.
2913 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2915 * i960-tdep.c (examine_prologue): Add new argument limit,
2916 which stops the scan at the end of the prologue, or at the PC.
2917 This fixes a problem where it walks down into the code for the
2918 user's statements if that code looks like function prologues.
2919 Mark Fox and I have been bouncing this code back and forth, making
2920 small changes to it. Callers changed to match.
2922 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2924 Cleanup for gdb-3.94 release final:
2926 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2927 the .c files from vx-share and nindy-share, from the various
2928 macros, since they are not found via ALLDEPFILES.
2929 (SFILES): Add tm-i960.h.
2930 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2931 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2933 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2934 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2936 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2938 * am29k-tdep.c: Add contribution line.
2939 (examine_prologue): Cache information about function prologues in
2940 the misc-function-vector to avoid lots of references over the
2941 serial line while examining instructions.
2943 * core.c (core_close): New function made from cleanup_core.
2945 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2946 remote-vx.c, remote.c, target.c, target.h,
2947 Update target_ops vector to add attach, close, and load entries.
2948 Use add_syms_addr_command, not add_file_addr_command, for
2949 add_file. Break out close routine from existing code.
2951 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2952 they are in an obstack.
2953 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2955 (define_symbol): Add symbol type parameter; change callers;
2956 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2957 it to influence the symbol class on the i960.
2958 (define_symbol): Swap LOC_CONST's into target byte order.
2960 * exec.c (exec_close): New function.
2961 (exec_file_command): Call it.
2963 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2964 Fix byte order of frame pointer.
2965 (read_var_value): Result of 0 if var's value can't be found,
2966 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2967 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2968 (locate_var_value): Use read_var_value and use its lazy address
2969 as the location of the var's value. Lint.
2971 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2974 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2975 obsolete Intel versions in favor of vxgdb versions.
2976 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2977 code dealing with byte order of values, which Intel did in host byte
2978 order rather than gdb-4's target byte order.
2979 (i960_frame_chain_valid): Move to nindy-tdep.c.
2980 (examine_prologue, skip_prologue, frame_find_saved_regs,
2981 frame_args_address, leafproc_return, saved_pc_after_call,
2982 pop_frame): Add vxgdb versions from Mark Fox.
2983 (examine_prologue, frame_struct_result_address): Add code
2984 to deal with the saved value of G13 (struct return address
2986 (frame_args_address): Modify Mark's version to prefer the
2987 saved value over the current value in the topmost frame.
2988 Cache result in the frame info to avoid performance hair in
2990 (print_fault): Add gdb960 code for printing faults.
2991 (_initialize_i960): Actually call check_host.
2993 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2994 add stub routines. FIXME, these currently just return zero!
2996 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2997 (attach_command): Call target_attach, not target_open, now.
2999 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3000 (child_attach): Rename from child_open.
3001 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3002 don't confuse it with a zero step_resume_break_address.
3004 * inftarg.c (child_detach): Eliminate inferior_pid test.
3005 (child_files_info): Clean up message a bit.
3006 (child_ops): Use child_attach, not child_open, to attach.
3008 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3009 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3010 findvar.c to here, since it depends on the contents of the
3011 shadow_contents of breakpoints, but keep if #if 0 since it is
3014 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3017 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3018 (ptype_command, display_command): Eliminate have_inferior_p and
3019 have_core_file_p in favor of target_has_stack or
3020 target_has_execution.
3021 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3022 code for actually finding the values of arguments, though we still
3023 keep track of the maximum stack offset for use in printing unnamed
3024 arguments. Handle missing FRAME_ARGS_ADDRESS.
3026 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3027 (struct nindy_regs): Define registers passed to/from nindy.
3028 (nindy_fetch_registers, nindy_store-registers): Translate between
3029 nindy and GDB formats for the registers.
3030 (dcache_init): Statically allocate the cache, since it was being
3031 allocated by a malloc that was never freed anyway.
3032 (nindy_create_inferior): Error, not core dump, if no exec file.
3033 (nindy_before_main_loop): Use target_load, not target_add_file.
3035 * remote-vx.c (net_load): Specify large timeout for load
3036 requests. Allow user to break out with INTERRUPT.
3037 (net_break): Remove useless code, clean up. Change callers.
3038 (parse-args, skip_white_space, find_white_space): Clean up arg
3039 parsing to cope with quoted strings.
3040 (net_wait, net_quit): Never call error, just return status.
3041 (vx_read_register, vx_write_register): Cleanup status checking.
3042 #ifdef the code based on which CPU we are using (960 or 68k),
3043 FIXME, this should be completely general but it isn't yet.
3044 (vx_xfer_memory, vx_resume): Cleanup status checking.
3045 (vx_run_files_info): Improve message.
3046 (vx_load_command): Renamed from vx_add_file_command. Allow load
3048 (net_ptrace): Remove unused routine.
3049 (vx_wait): Adopt code from vxgdb960 to cope with broken
3050 connections to target machine and prompt to disconnect. Remove
3051 debug printouts. Map some EVENT_'s to SIGnals.
3052 (add_symbol_stub, vx_open): Print names of object files we found,
3053 and "ok" if we read their symbols OK. Clarify output in general.
3054 (vx_attach, vx_detach, vx_kill): Add these commands.
3055 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3056 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3057 "info files" output, and create_inferior, since we already have
3060 * stack.c (frame_info): Replace Frame_unknown with 0.
3061 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3062 (return_command): Pop until the PC matches as well as the FP,
3063 so it works even if the FP is shared with another function,
3064 as in "frameless" or "leaf" procedures.
3066 * symfile.c (load_command): renamed from add_file_target_command.
3067 (add_syms_addr_command): renamed from add_file_addr_command.
3068 (add_syms_command): Stub to call target_add_syms.
3069 (_initialize_symfile): Change command names and descriptions,
3070 add-file => add-syms, and load from alias to its own command.
3072 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3073 maybe_kill_then_create_inferior): Default for attempts to start
3074 a process, if one is already running, is to ask about killing
3075 it and retry if yes.
3076 (upstack_create_inferior): #if-0 it, strata obsolete it.
3077 (push_target, unpush_target, pop_target): to_close() a target
3078 before unstacking it.
3079 (target_info): Renamed from target_files_info.
3080 (_initialize_targets): Rename "i files" as "i target", accessible
3083 * target.h: Improve comments about the target_ vectored routines.
3085 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3086 Convert commenting style to standard GNU style.
3087 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3088 (SKIP_PROLOGUE): No longer a no-op.
3089 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3090 (*_REGNUM): Sort register numbers.
3091 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3092 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3093 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3094 are now 10 byte extendeds, not 8 byte doubles.
3095 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3096 for nindy versus vxworks targets. FIXME, this should possibly go
3097 in the target vector.
3098 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3099 frame_saved_regs and arg pointer with each frame.
3100 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3101 (FRAME_ARGS_ADDRESS): Use cached result.
3102 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3103 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3104 (PRINT_RAMDON_SIGNAL): Call print_fault.
3105 (POP_FRAME): Now works.
3107 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3108 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3109 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3110 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3113 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3114 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3116 * valarith.c (value_subscripted_rvalue): Avoid handling
3117 floats and doubles specially; it gave alignment errors. Lint.
3119 * valops.c (value_of_variable, value_of_this): Error if unknown
3122 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3123 to avoid alignment problems.
3124 (value_print): Handle unknown value address.
3125 (cplus_val_print): Two args are ignored; remove them. Change caller.
3126 (val_print): Use unpack_long rather than pointer-deref.
3129 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3130 to avoid alignment problems.
3131 (value_being_returned): Error if return value unknown.
3132 (set_return_value): Add bogosity warning, FIXME. *
3134 * TODO: A woman's work is never done.
3136 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3137 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3138 Add ieee-float.o to OBS.
3139 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3140 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3141 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3143 Changes to generalize the VxWorks RPC protocol slightly, to handle
3144 i960 as well as 68000.
3146 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3147 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3148 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3149 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3150 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3151 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3152 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3153 so they will move in target byte order rather than network
3154 byte order (happens to be the same).
3156 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3158 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3160 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3163 Add contribution lines to various files, showing where they
3166 * breakpoint.c (break_insn, check_break_insn_size,
3167 read_memory_nobpt): Remove to mem-break.c.
3169 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3172 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3173 entry has bad register number. This change is not
3174 tested in this release, FIXME.
3176 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3179 * value.h: Force value's contents field to be aligned to hold
3180 at least a double or a long long (if supported). This avoids
3181 doing bcopy's in and out of the contents field.
3183 (step_1): Avoid coredump under obscure circumstances when we
3186 * symtab.h (misc_info): Add field to misc function vector for
3187 any kind of cached information the target code desires. AMD
3188 29000 uses this to avoid repeating examine_function_prologue's.
3190 * coffread.c: Lint. Remove static symfile, read_section_header.
3191 core.c (have_core_file_p): Lint: remove.
3192 expprint.c (print_subexp): Lint.
3193 infptrace.c, valops.c, valprint.c: lint.
3195 Roll in changes from vxgdb-5.0.1:
3197 * symtab.h: Comment byte order of each address class. Add
3198 LOC_LOCAL_ARG for frame-relative args (960).
3199 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3200 symtab.c, symmisc.c: ditto.
3202 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3204 * remote.c (remote_resume): Error if resume with a signal.
3206 * symfile.c (prim_record_misc_function): Clear misc_info.
3207 (fill_in_vptr_fieldno): Check stub type of arg.
3209 * valops.c (value_cast): Avoid looking up names of types whose
3210 name we don't know, to prevent coredump. Sun CC produces typedef
3211 rtx and the name of *rtx is zero...
3213 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3215 Roll in changes from final AMD 29000 port (Tiemann).
3217 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3218 for ../include/a.out.encap.h. This might not work now that BFD
3219 is separately compiled. Instead, BFD support for encap will have
3220 to translate machine type 29k into the right COFF_MAGIC.
3222 * infcmd.c: Remove references to inferior_pid that aren't used
3223 in actual ptrace calls; use target_has_execution, etc.
3224 (have_inferior_p): Remove function.
3225 (program_info): Print target info rather than "process number";
3226 avoid gratuitous messages unless from_tty.
3227 (run_stack_dummy, finish_command): Set proceed_to_finish.
3228 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3229 main.c: Lint. Lose have_inferior_p().
3230 inferior.h (have_inferior_p): Remove, lint.
3231 (proceed_to_finish): Add flag to ask that all regs be saved
3232 by normal_stop, for the few commands that need it, speeding up
3233 serial I/O. Add comments to stop_registers.
3235 * remote-eb.c: Remove newline from breakpoint message we grep
3236 for. Never time out when running the user program.
3240 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3242 Roll in changes from vxgdb-5.0.1:
3244 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3245 symbol in its raw form, we are processing an unlinked ".o" file.
3246 See if the target environment has assigned it an address, using
3247 target_lookup_symbol (VxWorks does), and enter it into the symtab
3250 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3251 68k versions for a simpler version that assumes zero FP at bottom.
3252 Fixes bug of truncated stack reports.
3254 * target.h (target_lookup_symbol): Define this routine's args
3255 and result, finally.
3257 * target.c (nosymbol): Default routine for target_lookup_symbol.
3258 (target_default): Default lookup_symbol and call_function too.
3259 (files_info): Only print has_all_memory warning if a non-dummy
3262 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3263 vx_convert_from_virtual): If target does not have floating point,
3264 zero register "values", and avoid doing cross-net conversions.
3265 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3266 (vx_open): Rearrange code that attaches to target and reads
3267 symbols for all loaded modules, to work if some of the modules
3268 are not accessible. Add symbol_stub() and add_symbol_stub()
3269 as callbacks from catch_errors(). Allow connect attempt to be
3270 interrupted painlessly with ^C (FIXME, there are still some bugs
3271 if the interrupt happens during symbol reading.). Print
3272 final message with puts_filtered, since symbol messages are
3277 * main.c (catch_errors): Only print errstring if non-null.
3278 (command_loop): Avoid an ioctl per command to test ISATTY.
3280 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3281 (vx_xfer_memory): Return correct result!
3282 (vx_files_info): Indicate whether target has float or not.
3283 (vx_lookup_symbol): Complain, not error, if target gone.
3284 (vx_open): Print "Connected" msg before disabling immediate-quit.
3285 [FIXME: lookup_symbol and vx_open changes need testing.]
3287 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3288 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3289 contributor lines and update copyrights to 1991.
3291 Changes from an attempted H-PUX host port:
3293 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3294 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3295 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3296 * remote-vx.c: include <sys/time.h> for HPUX.
3297 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3298 "core_file_command" routine to BFD regime. May not work yet.
3300 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3302 * xgdb.c: Replace X10 version with some VJ version.
3303 (FIXME: Its copyright assignment is not on record.)
3304 * xgdb.c: Update include files to X11R4 (Xaw crud).
3305 (xgdb_display_source, create_text_widget): fix call to
3306 get_filename_and_charpos. Rewack source window stuff for X11R4
3307 (gleaned from include files, and "nm's" of binary libraries, since
3308 I had no doc available).
3309 (append_selection, append_selection_word): Disable with FIXME
3310 since R4 changed interface here.
3311 (create_buttons): Add back the old set of buttons.
3312 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3314 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3315 Roll VERSION to 3.94 (not yet final though).
3317 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3319 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3320 obstack_int_grow, obstack_int_grow_fast): Eliminate
3321 cast on left of assignment, which gives MIPS cc fits and is
3324 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3325 F_ALIAS. Use printf, not fprintf, when not passing a file
3327 (compare_opcodes): Check that identical instructions have
3328 identical opcodes, complain otherwise.
3330 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3331 was reported by Roland McGrath.
3332 (unimp): Only match if exactly zero instruction. (Roland)
3333 (branches and traps): Generate all variations of these
3334 instructions with macros, based on a single call that defines
3335 each condition name and its binary representation.
3336 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3338 * valprint.c (val_print_fields): Take, and use, format parameter.
3339 This means that "p/x struct" again prints the elements in the
3340 desired format. Changed callers.
3342 * stack.c (frame_info): Use filtered output, and indicate wrap
3343 points. Remove kludgy formatting designed to avoid line wrap.
3345 * utils.c (wrap_here): If the line is already full (because
3346 we had printed a long indent or long wrapped string), do an
3347 immediate newline-and-indent.
3349 * m68k-pinsn.c (print_insn_arg): Bugfix from
3350 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3351 instruction is incorrectly disassembled as bkpt #8.
3353 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3354 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3355 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3356 and then will dump core (sometimes). I traced it back to an
3357 uninitialized symfile_name in psymtab_to_symtab.
3358 (const_vol_complaint): Add quotes to message.
3359 (define_symbol): Only believe line number if gcc_compiled.
3360 Avoid allocating symbol if we will not return it.
3362 Add target strata support so that newly established targets go
3363 into their right place in the target stack (e.g. a new exec file
3364 doesn't wipe out the ability to access the running process).
3366 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3367 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3368 and initialize it properly in all the targets.
3370 * target.h: Document strata. Change return type of push_target.
3372 * target.c (nomemory): new function for dummy memory access.
3373 (tcomplain): Rename complain, now also used in symfile.c.
3374 (push_target): Push targets within strata. New return value shows
3375 whether new target is on top of stack or not. Always keep dummy
3377 (target_files_info): Ignore dummy target.
3379 * core.c (core_open): Warn user, and skip accessing file, if the
3380 core target is not the topmost target in the stack.
3381 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3384 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3385 target_ops, it doesn't belong there since we have no regs there.
3386 Change name of target from machine => memory to clarify.
3388 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3390 * Freeze version 3.93 for release.
3392 * Makefile.dist: Handle vx-share and nindy-share subdirs
3393 properly when building gdb.tar.Z.
3395 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3396 printed in various places, so I could change just one copy.
3398 * dbxread.c, coffread.c: Change references to bfd->iostream
3399 to cast to FILE *, now that BFD avoids needing types defined
3400 in other header files.
3402 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3404 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3405 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3406 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3407 (actually gcc -Wall).
3409 * dbxread.c: Remove first_global_sym, last_global_sym, since
3410 they are never referenced.
3412 * defs.h (baud_rate): Declare.
3413 main.c: Define it, and add the -b option to set it.
3415 * gdb-int.texinfo: Add text on how to define a new host or target
3416 architecture, prompted by Per Bothner's questions about MIPS
3419 * gdb.texinfo: Document "complaints". Change doc of -q since
3420 gdb no longer prints the copyright and blurb if you specify a file
3421 name to be debugged (just like Emacs). Add doc for Nindy-specific
3422 command line flags for specifying target serial port and such.
3423 Update copyright to 1991.
3425 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3426 has taken over for us the job of ripping up executable files. The
3427 crud caused Per Bothner's port to not compile.
3429 * infrun.c (normal_stop): Avoid printing "Program exited
3430 normally" if we are in batch mode. This allows a GDB which
3431 executes a program on a target system, to behave like a Unix
3432 command (input from stdin, output to stdout, no extraneous
3435 * main.c (main): Allow additional machine-dependent command line
3436 options to be specified with the ADDITIONAL_OPTIONS,
3437 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3438 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3439 processing to occur just before the main loop with
3440 BEFORE_MAIN_LOOP_HOOK.
3441 (main): If a "core file" argument is specified, and it is not a
3442 core file, try it as a process ID to attach.
3443 (symbol_completion_function): Attempt to cope with
3444 "show screen-" TAB, not very successfully. This needs more work,
3446 (batch_file): New function, returns whether we are reading
3447 commands from an interactive tty on stdin, or from somewhere else.
3448 Called by normal_stop since it doesn't get from_tty passed down
3449 to it like many commands do.
3451 * remote-nindy.c: Handle command line options for nindy
3453 (nindy_before_main_loop): Prompt user for tty name if they
3454 don't specify it before getting to the interactive command loop.
3456 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3457 and -r command line options. Also add hook before main loop
3458 to make it easy to specify a tty.
3460 * TODO: More things to do, one done.
3462 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3464 * dbxread.c: Make complaint() calls pass pointer, not struct.
3465 Add complaints about badly formatted C++ type information
3466 (const/volatile indicator, and parse errors resulting in
3467 error_type). Fix C++ virtual member fn comment.
3468 (read_struct_type): Avoid bumping pointer if we got a parse
3469 error; this prevents our walking beyond the end of a string.
3470 Terminate loop on null char as well as semicolon.
3471 (process_one_symbol): Fix the LBRAC fix so that it uses the
3472 last previous SLINE, FUN, or SO record's PC address. C++ debug
3473 symbols did not have SLINE records in a useful order compared
3474 to the LBRAC records.
3475 (define_symbol): Handle "catch" records.
3477 * symtab.c (check_stub_type): Added new complain
3478 `stub_noname_complain' and added a consistency check to
3479 keep the debugger from crashing when finishing from an
3480 exception frame. A real fix will be needed later.
3482 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3484 * infcmd.c (attach_command): Make global.
3486 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3487 but make them easy to comment out. Perhaps later they should
3488 be enabled by what CPU you configure for? FIXME.
3489 (VERSION): Roll to 3.93.
3490 (pinsn.o): Remove rule for obsolete file.
3491 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3493 Run down a problem that manifested by printing the wrong function
3494 name in stack traces of read_ofile_symtab. Turned out that the
3495 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3496 the LBRAC symbol with an address in the *data* segment, which
3497 blew our binary search through the blocks.
3499 * dbxread.c: Use the complain() facility consistently to bitch
3500 about problems in the symbol file we are reading.
3501 (finish_block): Add code to check the nesting of the blocks;
3502 complain and Procrust them to fit if wrong.
3503 (make_blockvector): Check the order of the blocks, complain
3504 [but don't cope] if wrong.
3505 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3506 symbols to be sure their PC value is greater than the last SLINE
3507 (line number) symbol we've seen, complaining and adopting the
3508 SLINE PC value if wrong.
3510 * symfile.h (struct complaint, complaint_root, complain,
3511 clear_complaints): Add.
3512 * symfile.c (complain, complaint_root, clear_complaints): Add
3513 facility to deal with non-fatal complaints and to regularize their
3515 (symbol_file_add): Clear complaint counters to allow new complaints.
3516 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3518 * dbxread.c (dbx_symfile_read): Remember the address and size
3519 of the string table for the main symbol file, so we won't read it
3521 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3522 to avoid reading the string table yet again. Lint.
3523 (throughout): Improve filtered output, including word wrap.
3524 (read_range_type): Improve Bothner's fix to handle other types too.
3526 * utils.c: Improve line wrap implementation. Handle unlimited
3527 width by making chars_per_line unsigned.
3528 (puts_filtered): New, easy, function.
3530 * defs.h (puts_filtered): add.
3532 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3533 call the identical sort_symtab_syms() in symfile.c instead.
3535 * expread.y: Suggest the `file' command rather than `symbol-file'.
3537 * command.h (enum var_types): Add zinteger for seroable
3539 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3540 nested if's into a switch.
3542 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3543 we did not stop because of a breakpoint (it must have been for
3544 some other reason, like a "stepi"), so don't print anything.
3546 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3547 doesn't include <sys/types.h>, old SunOS's require it for
3550 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3552 A test port of gdb-3.92.6 to the Sony NEWS.
3555 Don't normally link in remote- or vx stuff.
3556 Some of it doesn't compile, and it wastes space for 99% of the users.
3557 Remove reference to no-longer-used HAVE_VPRINTF.
3558 Fixed BFD_DEP typo to BFD_DIR.
3560 Fix cast in arg to bfd_h_getlong.
3561 Make char *prefix be const.
3562 Fix how certain range types are mapped into builtin unsigned int types.
3564 Remove 2 #includes. They cause errors (on Sony, at least),
3565 and aren't needed (they wern't in earlier versions).
3567 print_address_symbolic should never demangle labels
3568 (since it prints *assembler-level* labels).
3570 [This was superseded by the change to printcmd below.]
3573 Add some "volatile" return types to avoid warnings.
3574 If MISSING_VPRINTF add vprintf function and not just macro
3575 (since vprintf is used in printcmd.c).
3577 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3578 (The latter isn't grokked by some PCC-based compilers.)
3580 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3582 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3583 * nindy-share/coffstrip.c
3584 Added some forward declarations (otherwise, gcc complains
3585 about implicit extern redefined as static).
3587 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3589 Changes inspired by Per Bothner:
3590 * printcmd.c (print_address_symbolic): Take additional parameter
3591 specifying whether to demangle.
3592 (print_address): Pass in asm_demangle to control demangling.
3593 (print_address_demangle): New fn, takes explicit arg to control
3595 * utils.c: Add new vars demangle and asm_demangle, and let them
3597 (fputs_demangled): If !demangle, just print the argument.
3598 (fprint_symbol): If !demangle, just print raw symbol.
3599 * valprint.c (val_print): Call print_address_demangle rather than
3600 print_address, to cause demangling to depend on the global
3601 rather than assembler-level demangling setting.
3602 * WHATS.NEW, gdb.texinfo: Document.
3604 * main.c (show_command): Show all settings if no arg.
3605 (initialize_main): Make "info set" the same as naked "show".
3606 * command.c (cmd_show_list): Handle prefix commands in the
3607 list, and print the name of the setting as well as its English
3608 description and value.
3610 Allow gdb functions to specify where a line should wrap if it
3611 exceeds the size of a terminal line. Use it to make the output
3613 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3614 of the right size when screen width changes.
3615 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3616 (wrap_here): New fn, indicates a point in the output where we
3617 should wrap the line rather than just letting it overflow at a
3619 (fputs_filtered): Implement wrapping.
3620 (n_spaces): New fn, returns a pointer to N spaces.
3621 (print_spaces_filtered): Use n_spaces.
3622 * defs.h (n_spaces): Declare.
3623 * stack.c (print_frame_info): Wrap with 4-space indent after
3624 fn name and before filename and line number.
3625 * printcmd.c (print_frame_args): Wrap with 4-space indent
3626 before each argument name is printed.
3627 * valprint.c (value_print): Wrap with no indentation before
3629 (val_print_fields): Wrap with indentation relative to nesting
3630 level before each field name.
3631 (val_print): Wrap with nesting indentation before array elements.
3632 * command.c (do_setshow_command): Avoid extra newlines,
3633 wrap with 4-space indent around values printed, end with period.
3634 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3636 * breakpoint.c (breakpoint_1): Implement addressprint for
3637 "info breakpoints" display. Change file name and line number
3638 format to " at file:nnn" rather than " (file line nnn)".
3639 * gdb.texinfo: Document.
3642 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3644 Frozen for gdb-3.92.6 release.
3646 README, WHATS.NEW: Update for 3.92.6 release.
3648 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3649 coffread.o from configs since it is now built by default.
3650 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3651 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3652 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3653 from configs since it is now built by default.
3655 Makefile.dist: Update for release 3.92.6. Handle files that
3656 have been moved to ../include, ../getopt, or ../bfd. Add
3657 saber.suppress and tests directory. Add config.status to
3658 the release (it will say "none").
3660 coredep.c: Minor formatting fixes.
3662 These changes were made in early December but only checked in now:
3663 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3664 nindy-share/nindy.c: lint
3665 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3666 register values coming back from the target; we store values
3667 in target byte order everywhere.
3669 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3671 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3673 * valprint.c (cplus_val_print, val_print_fields): New functions,
3674 which print C++ objects. They conspire to avoid printing a
3675 virtual base class more than once, following all the twists and
3676 turns of C++ virtual base rules.
3677 (val_print): Call the above rather than do it by hand.
3679 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3680 symbol file, not for added files like shared libs. This really
3681 needs to be generalized to a timestamp per file.
3683 * core.c (cleanup_core): Avoid coredump if no core file.
3685 * config.gdb: Accept -host or -target in place of +host or
3688 * coffread.c (find_linenos): Avoid desupported BFD interface
3689 to line numbers. We still read them manually rather than using
3690 BFD's "generic" features.
3692 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3694 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3696 * Makefile.dist: Eliminate use of $< in explicit targets.
3698 * readline/Makefile: Use $< rather than $*.c, which does not
3699 include the VPATH in GNU Make.
3701 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3702 copies of tconfig/i960, added for global configuration
3703 compatability. All i960 versions can read both coff and b.out.
3705 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3706 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3709 * TODO: Think of more things to do.
3711 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3713 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3714 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3715 64-bit float conversion.
3717 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3718 equivalent to sun?os4 so global config works.
3720 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3722 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3724 * main.c: Only declare linesize once; declare pagesize not at
3725 all, since it is never used.
3726 (main): Clear newly allocated line before it is used.
3728 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3730 Further stabilization for the Intel 960.
3732 * Makefile.dist: Parameterize the location of the "include"
3733 and "bfd" directories, as well as "getopt". Add symfile.c.
3734 Link in both dbxread and coffread. Fix up "make depend" to
3735 rewack the locations of include, bfd, and getopt in its output.
3737 * README: Document moving include files, improve some of
3740 * coffread.c: Move common code out to symfile.c. Change
3741 symbol_file_command style interface to use new *_symfile_init
3742 and *_symfile_read interface under BFD. Use BFD internal
3743 info to locate line table, symbols, etc.
3745 * core.c (core_fetch_registers): Rename to get_core_registers
3746 to avoid confusion with fetch_core_registers.
3747 (register_addr): Move to coredep.c, which is already machine
3748 dependent. This leaves core.c pretty clean of dependencies.
3750 * coredep.c (register_addr): Accept this routine from core.c.
3752 * dbxread.c: Move common code (with coffread.c, etc) into new
3753 symfile.c. Each psymtab now contains a pointer to the
3754 format-dependent function that knows how to read it in. Make
3756 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3757 (process_one_symbol): Add code to complain about a "compiler bug
3758 we muzzle here", if we actually see it.
3760 * eval.c (evaluate_subexp): Insert missing "break" statements
3761 in code that determines whether a variable is an lvalue in
3762 memory, register, or whatever. I detected this via a compiler
3763 bug in which it *almost* mashed out the whole switch statement.
3765 * gdb-int.texinfo: Add minor sections on configuring gdb for
3766 release, and about the README file.
3768 * infcmd.c (registers_info): Fix formatting somewhat. Still
3769 not as pretty as before, but it handles byte swapping.
3771 * remote-nindy.c: If data cache routines are interrupted while
3772 waiting for the remote end, be sure that any uninitialized cache
3773 blocks are on the free list, not on the valid list!
3775 * symfile.h: Flesh out this header file with all the various
3776 routines and variables that have been merged in from dbxread.c
3777 coffread.c, and symtab.c to symfile.c.
3779 * symfile.c: New file, containing code common to dbxread.c,
3780 coffread.c, and some code from symtab.c. All generic code for
3781 reading symbol files should be in here now.
3782 (unrecord_misc_function): Remove unused function.
3784 * symtab.h: Remove file-reading things to symfile.h.
3786 * symtab.c: Remove file-reading things to symfile.c.
3788 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3789 to decode i960 fault types.
3791 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3792 target.c: Change type of the "resume" function from int to void,
3793 since its result was never used.
3795 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3797 * main.c: Replace "stupid" with "caution"; you now "set caution
3800 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3802 * infcmd.c (do_registers_info): Call val_print to deal with the
3803 byte order of the registers being printed. FIXME, this makes
3804 the formatting of the output uglier.
3806 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3807 defined, call it for signals the debugger doesn't itself use.
3808 The i960 uses this for more detailed fault information.
3810 * remote.c (remote_open): If arg is null, print help rather than
3813 * sparc-xdep.c (register_valid): Avoid declaring size, since
3814 various modules will think of various sizes depending on the
3815 architecture of their tm-file. FIXME, we need protection against
3816 actually entering one of those modules, which would clobber
3817 storage if not for the target architecture compiled into gdb.
3819 * stack.c (up_command, down_command): Always print the frame
3821 (up_silently_command, down_silently_command): New commands
3824 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3826 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3827 more parameters than it used to.
3829 * findvar.c (registers): Increase slop to 256 bytes, which should
3830 protect us against even most RISC machines with large register
3832 (locate_var_value): Move declaration inside related ifdef.
3834 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3835 throughout, to avoid throwing away buffered input from the board.
3836 (nindy_wait): Supply_register takes addr_of_value, not value.
3837 (i960_print_fault): Renamed from i80960_fault.
3838 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3839 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3841 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3842 we can set the PC in the call to proceed(). Unpush nindy_ops
3843 before pushing it on top, to avoid message to user. Eliminate
3844 commentary from Unix machines that just misleads here.
3845 (reset_command): Fix error message to suggest target command.
3847 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3849 Release 3.92.5 as frozen.
3851 Stabilize the merged release...with help from lint, Saber C,
3854 Everywhere: Add include files needed to declare return types
3855 of functions called.
3857 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3859 * breakpoint.h: Add undeclared breakpoint functions, and some
3860 functions for display handling since I couldn't think of a better
3863 * breakpoint.c (insert_breakpoints): Make code for disabling
3864 shared library bkpts more likely to work. It's used when we
3865 rerun a program and stop before the shared library has been
3867 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3868 cast from pointer, so it squeezes through catch_errors.
3869 (bpstat_stop_status): Fix logic broken some time ago. We now
3870 always create a bpstat if the stop address matches a breakpoint,
3871 even if we don't stop there -- just like the old code used to do
3872 before I got my fingers into it (sigh).
3873 (breakpoint_1): Print "ignore count" after "stop only if"
3874 condition, since that's how it actually works.
3875 (mention): Handle watchpoints as well as breakpoints.
3876 (watch_command): use set_raw_breakpoint and mention to do most
3877 of the work (and initialize all the fields!). Only pass one
3878 arg to parse_c_expression, since that's all it takes.
3880 * command.c (not_just_help_class_command): Rename arg to args
3881 since we ignore "unused argument" warnings on vars named "args".
3882 inflow.c (child_terminal_info): ditto.
3883 infptrace.c (kill_inferior): ditto
3884 main.c (catch_errors, version_info, quit_command, pwd_command,
3885 source_command, dump_me_command, editing_info,
3886 set_history_size_command, set_history, show_history,
3888 stack.c (locals_info): ditto
3889 target.c (target_files_info): ditto
3890 valprint.c (set_input_radix, set_output_radix): ditto
3892 * core.c: Remove old variables for handling core and exec file
3893 sections (data_start, data_end, stack_start, stack_end,
3894 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3895 text_end, exec_data_start, exec_data_end, text_offset,
3896 exec_data_offset, data_offset, stack_offset). They're
3897 superseded the more general build_section_table and
3899 (get_exec_file): Mention the `file' command.
3900 (read_memory_check): Rename to memory_error, and only call it
3901 in the case of an actual error.
3902 (read_memory, write_memory): call memory_error.
3903 (core_fetch_registers): Register section name is ".reg".
3905 coredep.c: Remove a bunch of crud now that all this file does
3906 is pull the registers out of a core file.
3907 (fetch_core_registers): Rewrite to actually work, I hope.
3909 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3910 Replace index() with strchr(). Remove all the pre-BFD macro
3911 definitions for accessing the symbol file.
3912 (struct dbx_symfile_info): Encapsulate the information that
3913 dbx_symfile_init needs to pass to dbx_symfile_read in this
3916 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3917 dbx_symfile_discard): Rearrange symbol file reading to divide
3918 the format-specific part from the format-independent part,
3919 leaving the format-independent part such as file name expansion
3920 and opening in symtab.c. This replaces
3921 partial_symbol_file_open and partial_symbol_file_read.
3922 Symbol_file_read, add_file, add_file_target_command,
3923 add_file_addr_command move to symtab.c. Pass an explicit
3924 "mainline" flag for when reading the main symbol table, rather
3925 than relying on the offset address to be zero or nonzero.
3927 (dbx_symfile_read): Don't allow void *'s to be printed as
3929 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3930 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3931 macro" debug version really work.
3932 (read_dbx_symtab): Remove unref'd parameter inclink.
3933 Avoid swapping N_SLINE symbols, for speed.
3934 Merge N_TEXT!N_EXT case with the other external symbol
3935 definitions' case. Add comments.
3936 (start_psymtab): Allocate the symfile name in the psymtab on
3937 the psymbol_obstack, rather than using the caller's storage.
3938 (end_psymtab): Only allocate a dependencies list if there are
3940 (psymtab_to_symtab_2): Use BFD when reopening file to read
3941 its symbols for real.
3942 (read_struct_type): Add FIXME comments where it needs work
3944 (read_huge_number): Add FIXME about overflows.
3945 (read_range_type): Add FIXME about comparing a long to 1<<32.
3947 * coffread.c: Minor changes to move things closer to the new
3948 regime with symtab.c and dbxread.c Major work is still needed
3951 * exec.c (exec_file_command): Remove old variables (see core.c
3953 (xfer_memory): If memory transfer is right at the end of a
3954 section, don't lose.
3956 * findvar.c (get_saved_register): If value is in a real
3957 register, LVAL is lval_register, not lval_memory.
3959 frame.h: Declare print_sel_frame and record_selected_frame.
3961 gdb-int.texinfo: New file, for GDB internals documentation.
3962 Very simple, unformatted doc of cleanups is there for now.
3964 gdbcore.h: Remove obsolete variables that described a.out
3965 section addresses and offsets. (See core.c above.)
3966 Declare fetch_core_registers and registers_fetched.
3968 getopt.c: Declare char *alloca(); even on SPARC.
3970 infcmd.c (run_command): Call target_kill rather than
3972 (step_command, next_command, stepi_command, nexti_command):
3973 Declare from_tty parameter even though we don't use it.
3974 (run_stack_dummy): argument BUFFER is a char array, not
3975 a pointer to REGISTER_TYPE.
3976 (finish_command): using_struct_return needed a value *,
3977 not a struct symbol *.
3979 * infptrace.c (child_xfer_memory): To avoid dependency on
3980 where sections are in memory, try PT_WRITE_D and if that fails,
3981 try PT_WRITE_I. Most Unixes don't care which you use.
3983 * infrun.c (step_resume_break_shadow): Change to array to
3984 match other breakpoint shadow storage.
3985 (clear_proceed_status): Pass address of bpstat to
3986 bpstat_clear, not the bpstat itself.
3987 (child_create_inferior): FIXME comment about if the child
3989 (start_inferior): Remove old function.
3990 (child_open): Use target_kill rather than kill_inferior.
3991 (wait_for_inferior): Ditto.
3992 (insert_step_breakpoint, remote_step_breakpoint): Use
3993 new step_resume_break_shadow.
3995 * inftarg.c (child_wait): If all child processes die,
3996 pretend that the one being waited for exited with signal 42.
3998 * main.c (command_line_input): When scanning for comments,
3999 don't coredump on unclosed quotes.
4000 (quit_command): Use target_kill rther than kill_inferior.
4001 (_initialize_main): Rename class_user from "user" to
4004 * printcmd.c (print_command_1): Initialize "fmt" if no format
4005 is specified by the user.
4006 (print_frame_args): Only add to args_printed if we are
4007 actually fetching args from the stack (avoiding undefined
4009 (_initialize_printcmd): Remove bogus \{ from string.
4011 * remote-eb.c (eb_open): Avoid coredump on no argument.
4013 * remote-nindy.c: Bring out of Intel environment into new
4014 target environment. Remove all conditional compilation on
4015 I80960. Massive hacking throughout.
4016 (nindy_xfer_inferior_memory): New routine stolen from
4018 (nindy_create_inferior): New routine pieced together, probably
4019 not quite working yet.
4020 (nindy_ops): New target_ops struct for nindy.
4022 * remote-vx.c: Use write_memory rather than target_write_memory
4023 to get error checking.
4024 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4026 (vx_create_inferior): Use target_terminal_ours...
4028 * signame.c (_initialize_signame): Always initialize, since
4029 we need the table for things other than psignal.
4031 * solib.c (solib_add): Use symbol_file_add, not add_file.
4032 (solib_address): Return boolean result rather than struct
4033 pointer which nobody else knows the type of.
4035 * sparc-tdep.c, valops.c: Use write_memory rather than
4036 target_write_memory, to get error checking.
4038 * stack.c (locals_info, catch_info, args_info,
4039 get_selected_block, frame_command, up_command): Use
4040 target_has_stack, rather than have_inferior_p or
4043 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4045 * symfile.h: New file, defining the interface between the
4046 generic and object-file-specific symbol reading code.
4048 * symtab.c: Move generic symbol-reading interface to symtab.c,
4049 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4050 table to map BFD targets to symbol-reading modules in GDB.
4051 Change index to strchr.
4052 (lookup_struct_elt_type): Use error() rather than hand-made
4053 simulations thereof.
4054 (lookup_partial_symbol): Speedup slightly when length == 0.
4055 (symbol_file_add): New function.
4056 (symbol_file_command): Call it.
4057 (symfile_open, symfile_init): New function.
4058 (add_file_target_command, add_file_addr_command): moved from
4061 * target.c (target_command): use target_kill.
4063 * target.h (target_files_info): Don't declare, never called
4066 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4067 files to determine stack end address.
4069 * valarith.c (value_x_binop, value_x_unop): Change error message
4070 to be more useful. Pass proper argument to value_struct_elt.
4072 * valops.c (value_assign): FIXME comment that long long
4073 bitfields will break here.
4075 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4076 Update `make saber_gdb' to work better.
4078 * TODO: A woman's work is never done.
4080 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4081 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4082 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4083 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4084 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4085 valops.c, valprint.c, exec.c: Lint.
4088 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4090 Continuing Intel 960 port merge of GDB.
4092 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4093 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4094 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4095 Wack over "make depend" so it handles files in subdirectories
4096 vx-share, nindy-share, bfd, and in the current directory.
4098 * blockframe.c (get_prev_frame_info): Remove fatal error
4099 if stack not defined.
4101 * core.c (core_open, core_detach): New functions that handle
4102 the old "core-file" command as "target core" and "detach" instead.
4103 (core_file_command): Call them.
4104 (core_xfer_memory): Use common routine xfer_memory.
4106 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4107 dbxread now uses bfd for everything but symbol reading itself.
4108 BFD internals are used to drag out the relevant file offsets.
4109 (partial_symbol_file_open): Change args all around for BFD.
4111 * symtab.c: Rename "value" to "val" everywhere, so we can
4113 (symbol_file_command): New command, moved from dbxread.c
4114 and coffread.c. It uses BFD to read the file, then vectors
4115 based on its type, to dbx or coff symbol readers.
4116 * symtab.h: Extern a few vars for symbol_file_command.
4118 * target.h: Breakpoint takes a char * save area, not a char **.
4120 * valprint.c (val_print): When unpacking bitfields, offset
4121 the address in gdb of the value, if it is declared with a shorter
4122 type. Remove the last "runtime kludge test" of host byte order.
4124 * utils.c: Remove old my_bfd_read routine.
4126 * stack.c (frame_info): Use target_has_stack. Print program counter
4127 register's actual name rather than "pc", since it's called the
4128 "ip" (instruction pointer) on the i960 (sigh).
4130 * target.c (target_command): Add command for selecting a target
4131 type and calling its open routine. This is used for initiating
4132 communication with a particular target, in a generic way.
4134 * tm-i960.h: Update for modern gdb. Remove semicolons from
4135 various macros. Handle reading struct return convention, and
4136 error-out attempts to return structs with the "return" command.
4137 Be sure gdb doesn't think we know how to call functions in the
4140 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4141 to i960_xxx in lower case.
4142 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4143 not being defined yet.
4145 * remote.c (remote_open): Call start_remote to initialize
4146 wait_for_inferior during open.
4147 (remote_xfer_inferior_memory): Return length written rather
4150 * remote-vx.c (target_command -> vx_open): Use new generic
4152 * remote-eb.c, inftarg.c, exec.c: ditto.
4154 * infrun.c: Fix comments.
4155 (attach_program -> child_open): Use new generic target command.
4156 (wait_for_inferior): Clear saved register values before target_wait,
4157 so target_wait can set some of them if convenient.
4159 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4160 Return success indicator, not void.
4161 (child_xfer_memory): Avoid fetching initial word if we'll
4162 overwrite it anyway.
4164 * infcmd.c (attach_command): Use new generic target open routine.
4165 (_initialize_infcmd): Update doc on attach and detach commands.
4166 (do_registers_info): Merge in a byte-order problem as a FIXME
4169 * findvar.c (find_saved_register): Avoid problem in current frame.
4170 (read_relative_register): Ditto.
4171 (write_register): Convert byte order on the way out.
4173 * exec.c (file_command): Add.
4174 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4175 (xfer_memory): Common function between core_xfer_memory and
4177 (exec_xfer_memory): Use it.
4179 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4181 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4182 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4183 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4185 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4187 Merge Intel 960 port of gdb, continuing...
4189 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4190 symbol_file_command): Pass from_tty arg to hush 'em up.
4192 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4193 Add magic numbers for 960 COFF format.
4195 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4197 Merge Intel 960 port of gdb, from Intel "1.2" release.
4199 CHANGE_LOG entries from their port, which was based on
4202 Thu Sep 6 11:02:22 PDT 1990
4203 Remove temp file if download is interrupted.
4205 Wed Aug 1 09:08:33 PDT 1990
4206 Now uses binary protocol to talk to NINDY.
4207 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4208 Times out after 5 seconds when trying to talk to NINDY.
4210 Tue May 29 12:54:49 PDT 1990
4211 Added variable baud rate (-b switch).
4212 Source code reorganization.
4214 Thu Apr 26 11:09:55 PDT 1990
4215 More cleanup of batch mode; specifically, execute "-s", "-e", and
4216 "-se" switches as soon as they are encountered on the invocation line.
4218 Fri Apr 20 13:47:15 PDT 1990
4221 Thu Apr 19 09:54:28 PDT 1990
4222 Add 'reset' command.
4224 Wed Apr 18 09:48:07 PDT 1990
4225 After opening remote tty, wait for 1 second to go by without input
4226 from it before trying to talk to NINDY (fixes problems with the
4227 Heurikon HK80/V960E).
4229 Mon Apr 4 16:33:05 PDT 1990
4230 Some output was not being suppressed in 'batch' mode.
4232 Thu Mar 22 15:31:11 PST 1990
4233 Ask user if old symbol table should be deleted when new file is
4236 Allow user to run a program downloaded before gdb960 was brought up.
4238 Correct "exec-file" help message for i80960 context.
4240 Correct bug in calculating user space address: could occasionally
4241 corrupt user program.
4243 Make sure to zero low-order bits in rip's because of bug in 960CA
4244 A-step part: could cause operation faults when "next"ing across
4247 Correct bug that made it impossible to get source line numbers for
4248 code loaded at addresses higher than 0x7fffffff.
4250 Wed Jan 10 12:43:22 PST 1990
4251 Open remote tty for exclusive use.
4253 Fri Jan 5 12:14:42 PST 1990
4254 Correct disassembly (CA manual was right after all):
4255 opcode for sysctl is 0x659
4257 Mon Oct 23 12:03:04 PDT 1989
4258 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4260 Mon Oct 16 14:15:09 PDT 1989
4261 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4263 Mon Oct 2 15:56:31 PDT 1989
4265 Added 960CA disassembly support.
4267 To simplify maintenance:
4268 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4270 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4271 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4272 - made disassembly interface identical to that in gdmp960.
4276 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4278 * target.h: Allow targets to stack. Add target_has_memory,
4279 _registers, etc. Restructure memory access and "info files"
4280 to walk the target stack.
4281 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4282 target.c: Change tables to match target.h.
4283 * inflow.c (child_mourn_inferior): pop child_ops.

4287 * remote-eb.c: New memory regime, new info files.
4288 * remote-vx.c: New memory regime, new info files. Now use
4289 separate targets for VxWorks attachment to machine, and
4290 actually running a process under VxWorks, since one has
4291 stack & execution & regs and the other doesn't.
4292 * remote.c: New memory regime, new info files.
4293 * sparc-xdep.c (fetch_core-registers): New memory regime.
4294 * target.c: New routines and support for stacked targets,
4295 new memory regime, new info files regime.

4301 * exec.c (build_section_table): Iterate all sections and
4302 record what gdb needs to know about them.

4314 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4316 * inferior.h (attach_flag): Export.
4317 * infcmd.c (run_command): use new target_create_inferior.
4318 * infrun.c (child_create_inferior): Don't return result.

4324 since been deleted, such as temporary breakpoints.
4325 infcmd.c (program_info): ditto.
4327 * core.c (core_file_command): Display the frame where the core
4332 * remote-vx.c (target_command): Merge in target command from
4333 targ-vx.c. A few other cleanups.
4335 * TODO, Projects: Lots more stuff to do...
4337 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4339 Massive changes to wall off the remote-debugging interface
4340 behind a function vector. The port to handle VxWorks targets
4341 is also part of this.
4343 All files: Replace references to renamed functions,
4344 remove references to remote_debugging, remove references to
4345 have_include_file, have_core_file in favor of target_has_stack,
4346 target_has_memory, etc.
4348 * Modularize the breakpoint interface.
4349 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4350 a breakpoint instruction.
4351 breakpoint.c: struct breakpoint's shadow_contents now sized as
4353 (insert_breakpoints): Vector to target to install breakpoints.
4354 (remove_breakpoints): Vector to target here too.
4355 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4356 sparc-tdep.c (single_step): Use new breakpoint interface for
4357 the single-step breakpoints.
4358 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4359 New file, contains routines to insert and remove breakpoints by
4360 reading out the old contents and later replacing them. This is
4361 how ptrace breakpoints work, and many remote systems as well.
4363 * tm-vxworks68.h: New config file, overrides a few things for
4364 Wind River's preferences.
4366 * target.h: New file, for transfer vector used to talk to the
4367 inferior (child, attached, core, exec, remote, etc). All accesses
4368 to the thing being debugged should come through these vectors.
4369 target.c: New file, routines to handle transfer vector.
4370 (various files): Add transfer vectors XXX_ops for the various
4371 targets and pseudo-targets (core files, etc) we support.
4373 * breakpoint.c (bpstat_stop_status): Further explorations of
4374 watchpoints and why things don't work all the time.
4375 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4377 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4378 the local gdbinit if it doesn't already have it.
4380 * core.c (core_ops): add and install.
4381 Allow core debugging without exec file.
4383 * dbxread.c (free_and_init_header_files): Merge two fns.
4384 (end_symtab): Free named symbol table when a new version comes in.
4385 (read_dbx_symtab): Relocate all kinds of symbols with base
4386 address. First step toward handling different text, data, bss
4388 (add_file_addr_command): Renamed add_file_command.
4389 (add_file_command): Vector to remote handler.
4390 Add "load" as an alias for "add-file" command.
4392 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4393 non-returning functions.
4395 * exec.c: Add exec_ops, and push it as a target when an exec
4398 * infcmd.c (run_command): Pass executable file name and arg list
4399 separately when starting an inferior. Permit "run" when no exec
4400 file is specified, for VxWorks.
4401 (detach_command): Move to child_detach in inftarg.c.
4403 * inftarg.c: New file. Unix-child-specific routines, and the
4404 child_ops structure.
4406 * inferior.h (registers): Export "registers" as the way for
4407 target dependent register handlers to find gdb's local copy of
4408 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4409 since it is now used by places that want wait_for_inferior to
4410 handle the grunge but want to see every trap from the inferior.
4412 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4413 Eliminate remote_debugging hooks in terminal handling.
4415 * infrun.c: Replace start_inferior with child_create_inferior.
4416 Move all the hair of Unix shells and ptrace idiosyncracies into
4417 child_create_inferior, so remote handlers don't have to deal.
4418 Remove running_in_shell. Rename stop_after_attach to
4419 stop_soon_quietly, and use it in a few other places where we want
4420 to just call wait_for_inferior and get control back on the first
4421 trap. trap_expected now never takes a value > 1.
4422 (init_wait_for_inferior): Initialize static vars when a new
4425 main.c (gdbinit): Add new hook for .gdbinit file name, let
4426 it be overridden by config files as GDBINIT_FILENAME.
4427 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4428 Both of these are used for VxWorks gdb.
4430 mcheck.c: rename include file "gmalloc.c" to avoid problems
4431 with system include file "malloc.c".
4433 param-no-tm.h: New include file, same as param.h but does not
4434 include the default "tm.h" file. This is used in files where
4435 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4437 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4439 remote-vx.c: New file, VxWorks remote debugging support. Uses
4440 RPC routines that are shared with the target system, in directory
4443 remote.c: Vectorize remote interface.
4445 source.c: Globalize source_path, and make an alias "l" for "list"
4446 since we now have the "load" command.
4448 sparc-xdep.c: Use new param-no-tm.h.
4450 symmisc.c (free_named_symtab): Add new function from Wind River.
4451 However, ifdef it out for now while we think about what it should
4454 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4456 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4457 non-Unix-children handle this with their own code in the target
4460 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4461 source and target lists. Add vx-share to default list of include
4462 directories. Add new files to src and target lists: mem-break,
4463 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4464 ${srcdir} versions of munch and createtags are used.
4466 * valops.c (find_function_addr): Split out of call_function.
4467 (call_function_by_hand): Rename call_function; this function
4468 calls functions in the target by laboriously patching the target
4469 word-by-word with the right stack, args, regs, etc.
4472 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4474 Handle AMD 29000 a bit better.
4476 * remote-eb.c (readchar): Mask received char log to make it readable.
4477 (remote_start): Pass arguments down to executing program.
4478 Make startaddr unsigned.
4479 infrun.c (start_inferior): Accept args, pass them to
4481 infcmd.c (run_command): Pass args down to start_inferior.
4483 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4484 the target object file format.
4485 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4487 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4488 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4490 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4492 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4493 * TODO: We did a few things, we have more to do though.
4495 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4496 * inflow.c (inferior_died): Clear deferred stores.
4498 * Debug problems with dummy frames and calls to the inferior.
4499 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4500 * sparc-tdep.c (do_restore_insn): Simplify.
4501 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4502 (sparc_push_dummy_frame): Simplify and fix what we push.
4503 (sparc_pop_frame): Slightly more hair here, deciding whether
4504 we are restoring a saved PC or returning to a return address in %i7.
4505 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4507 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4508 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4509 * obstack.h (chunkfun): ditto.
4510 * defs.h (xmalloc, xrealloc): ditto
4512 * utils.c (quit): Grab the terminal from the child if necessary.
4514 * inflow.c (term_status_command): Rename to term_info, change
4517 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4518 (is_delayed_branch): Speed up.
4519 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4520 Still missing some float ops, and needs testing.
4522 * Support for input and output radixes other than base 10
4523 * defs.h (input_radix, output_radix): Declare.
4524 * expread.y (yyparse, parse_number): Handle changes of input
4525 radix, and ambiguous names-or-numbers in radixes >10.
4526 * printcmd.c (print_scalar_formatted): Print formatted hex
4527 numbers in varying column widths.
4528 * valprint.c (val_print): Use output_format to print scalar ints.
4529 (set_input_radix, set_output_radix, set_radix): Create.
4530 (set_output_radix): Set output_format from output_radix.
4531 (_initialize_valprint): add `set radix' but leave the others off.
4533 * main.c (execute_command): Let stupid questions be turned off.
4534 (_initialize_main): Handle "set stupidity", etc.
4536 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4537 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4539 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4541 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4542 bfd stuff is still screwed up, but with some manual work, it
4545 * breakpoint.c (bpstat_do_actions): Start over if a command
4546 proceeds the inferior, since the inferior will have stopped and
4547 will need to have its new stop-actions taken care of.
4549 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4550 compiler fits, simplify it.
4552 * gdb.texinfo (directory command): Doc new dir command.
4553 source.c (directory_command): "dir" now puts things on the front
4554 of the path, moves dups up front, and handles multiple names
4555 on the command line, inserting each one in order. It also
4556 blows away cached line and full_filename info.
4558 * stack.c (backtrace_command): Skip "more stack frames follow"
4561 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4562 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4563 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4564 The only odd one was Gould NP1, which had defined vprintf to
4567 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4568 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4569 variable, inspect_it.
4570 valprint.c (print_string, val_print): Use the global inspect_it
4571 to indicate whether to print in Epoch style or normal style.
4573 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4575 * printcmd.c (call_command): add an alias for the "print" command
4576 which runs expressions and doesn't print the result if void.
4577 (print_command_1): implement it.
4579 * command.c: Remove #if 0'd code. Initialize all the fields
4580 in add_cmd (). Rename do_nothing_command to
4581 not_just_help_class_command, and make it externally visible.
4582 command.h: add user_commands to struct.
4583 * main.c (define_command): Don't overload c->function with a char
4584 string as well as a function pointer.
4586 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4587 calling convention of value_struct_elt () that got dropped in
4590 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4591 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4593 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4595 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4596 until a good time (e.g. when we are about to run the child),
4597 saving ptrace calls.
4598 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4599 * tm-sparc.h: define DO_DEFERRED_STORES.
4601 * sparc-xdep.c (store_inferior_registers): when storing float
4602 registers, don't store stack regs too. When storing the SP,
4603 however, DO store the stack regs too. This fixes a bug in which
4604 the dummy frame is not recognized when a call_function finishes,
4605 because its frame pointer (in the stack regs) was never
4607 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4608 even though we don't know how to read them from an inferior.
4609 valops.c (call_function): Comment about storing SP.
4611 * infrun.c (save_inferior_status): Save away the original bpstat
4612 chain so it can be restored later. Install the copied version for
4613 use by whoever saved the status. It will be blow away by
4614 restore_inferior_status, and the original chain restored. This is
4615 important for people who have pointers into the original.
4617 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4618 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4619 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4622 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4624 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4625 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4626 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4628 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4630 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4631 Store the baseclasses in a type struct starting from array element
4632 0 rather than from the unusual array element 1.
4634 dbxread.c: the above.
4635 (virtual_context): Add
4636 Read new debug information about which virtual function table
4637 a virtual function is from, and store it in fn_field.fcontext.
4639 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4640 TYPE_FN_FIELD_STATIC_P.
4642 symtab.c: the above.
4643 valops.c: the above. Handle pointer casts of object *'s.
4644 (search_struct_method): Add.
4645 (value_struct_elt): First arg is now a pointer to a value, and is
4648 valprint.c: the above.
4649 values.c (value_virtual_fn_field): Add type arg. Handle
4650 offsetting to the proper object when calling virtual fns.
4652 (baseclass_addr): Add valuep arg.
4654 * README: Document the current state of BFD config (missing).
4655 * TODO, ChangeLog, Makefile.dist: Roll version.
4656 * WHATS.NEW: Add summary of changes since 3.5.
4658 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4660 * dbxread.c (read_struct_type): Clear bit vectors whenever
4662 symtab.c (B_CLRALL): define.
4664 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4665 using == rather than =. Huh... This fixes the dreaded problem
4666 wherein builtin_type_int becomes TYPE_CODE_FLT.
4668 * core.c (info_files): Show the inferior pid.
4670 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4671 already knows how to look in the source directory.
4673 * Remove psymtab hair from many places. Remove duplicated code
4674 for searching symbol tables. Hide psymtabs from most places.
4675 Make it fast to get from a psymtab to its symtab.
4677 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4678 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4679 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4680 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4681 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4682 new symtab completely. New psymtabs get symtab pointer
4683 initialized to zero. Remove MI warning printf.
4684 symtab.h: Comments. Add psymtab to symtab pointer.
4685 (PSYMTAB_TO_SYMTAB): New macro.
4686 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4687 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4689 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4691 (print_frame_info): Avoid special-casing symbols that have not yet
4694 * source.c (open_source_file): Quick path if we have already
4695 located the source file by its full name.
4697 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4698 find_pc_psymtab. When a name is found in the misc function
4699 vector, search the symbol table for its mangled name, not the
4700 name that the user typed.
4702 * bfd.h: Fix missing comment terminators, make #endifs match.
4704 * valarith.c (value_less): Handle unsigned int comparisons.
4705 Add FIXME about pointer compares, which assume host and target
4706 pointers are the same.
4708 * command.c (do_nothing_command): lint
4709 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4710 fix comments on debug symbol format for visibility. Actually set
4711 visibility of symbols.
4712 main.c (echo_command): lint; use <readline/history.h>.
4713 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4714 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4715 pointing past end of allocated memory; saber complains.
4716 obstack.h: Declare the external functions that we use.
4717 valarith.h: use <string.h>
4718 solib.c (solib_add): lint.
4720 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4722 * main.c (initialize_main): Default info_verbose to off, now that
4723 symbol reading is fast.
4724 (quit_command): Avoid clobbering exec_bfd while quitting.
4726 * Initial BFD (binary file diddling library) merger:
4727 coffread.c: Change AOUTHDR to struct exe_hdr.
4729 core.c: initialize initialized data at compile time.
4730 (core_file_command): Move from coredep.c, convert to bfd.
4731 (xfer_core_file): Convert to bfd.
4732 exec.c (exec_file_command): use bfd routines.
4734 mips-tdep.c: Remove exec_file_command and friends.
4737 * coredep.c: (fetch_core_registers) Convert core_file_command to
4738 fetch_core_registers.
4739 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4741 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4742 (my_bfd_read): More bogosity, which I don't think we call.
4743 (program_name): Remove this atrocity asap!
4745 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4748 values.c: allocate_repeat_value was not clearing the
4749 optimized_out field.
4750 (value_static_field): minor stylistic fix (wrong macro was used).
4751 valops.c (value_struct_elt_for_address): didn't work for C++
4754 * signame.c (_initialize_signame): Initialize signal names once.
4756 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4757 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4758 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4760 * remote-eb.c: Support user-settable baud rates on the serial port.
4762 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4764 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4766 * tconfig/sun3os4: Remove warning about native assembler,
4767 since it also occurs in the xconfig file.
4769 * findvar.c (registers): Allocate some slop after `registers'
4770 to prevent stray accesses from trashing the next variable.
4772 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4773 on the sun-3, by changing the #ifdef from `sun3' (which is not
4774 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4775 vars, which happened to follow `registers' in the executable.
4777 * readline/history.c (history_search): Heed gcc-2's advice
4778 and parenthesize && inside ||).
4780 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4781 tm-29k.c: Insert FSF copyright headers.
4783 * remote-eb.c: Better comments.
4785 * Makefile.dist: Update to 3.91.6.
4786 * TODO: note PREPARE_TO_STORE problem.
4788 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4790 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4792 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4794 * infrun.c (wait_for_inferior, at end): Don't set up
4795 prev_* if the inferior no longer exists.
4797 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4798 CANNOT_EXECUTE_STACK.
4799 valops.c (call_function): Use it.
4801 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4803 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4804 infrun.c (wait_for_inferior, 2 places): Use it.
4806 * values.c (value_being_returned): Only use
4807 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4809 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4810 right thing for remote-eb.c.
4812 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4813 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4815 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4816 (FRAME_FIND_SAVED_REGS).
4818 * findvar.c ({fetch,store}_registers): Check for
4819 REMOTE_{FETCH_STORE}_REGISTER macro.
4821 * findvar.c (get_saved_register): Add argument lval and
4822 change meaning of argument addr.
4823 findvar.c: Change calls to get_saved_register to reflect
4824 new calling convention.
4825 valops.c (value_assign): Use get_saved_register instead of
4826 find_saved_register.
4828 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4830 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4831 an (uninitialized) pointer to one. Use "&" when passing it
4834 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4836 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4839 * coffread.c (symbol_file_command): Put semicolon after
4841 Put safe_to_init_tdesc_context in #if defined (TDESC).
4842 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4843 coffread.c: #include <sys/stat.h>.
4844 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4845 Add missing ')' in check for "lc%" and friends. Remove
4847 Declare read_one_sym() at top of file.
4848 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4849 MC68WRMAGIC can have the same value without causing a duplicate
4852 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4854 * Allow a Makefile to be built without building the
4855 tm and xm file links that screw up builds in subdirectories.
4856 This is done with `config.gdb none', then you can do things
4857 like `make gdb.tar.Z'.
4858 * tconfig/none: Config file for no target system
4859 * xconfig/none: Config file for no host system
4860 * config.gdb: If no TM or XM files are called out by the
4861 host or target file, don't make links for them.
4863 * cplus-dem.c: Add documentation.
4865 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4866 simple error, so the user's gdb doesn't crash due to some object
4867 file problem (e.g. somebody is rebuilding the file out from under
4870 * printcmd.c (print_address_symbolic): demangle the symbol.
4872 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4873 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4874 (alldeps.mak): sort and uniq all results from this; duplicates
4875 hose gdb.tar.Z link building. Remove RCS files from
4876 tconfig and xconfig. Add config files for sun386. Add
4877 a few odd files to OTHERS and HFILES.
4879 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4881 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4882 Roll version number to 3.91.5. Make lint work in bindir.
4884 * README: Document cross-debugging and new file structure.
4886 * blockframe.c: Lint. Include "value.h" to declare read_register.
4887 (find_pc_partial_function): remove duplicate line.
4889 * command.h: Lint. Declare error_no_arg and dont_repeat.
4891 * tm-news.h: Remove inadvertently duplicated stuff.
4893 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4894 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4896 * config.gdb: Allow `config.gdb host target' form. Clean
4897 up previous change that printed bogus messages when you just said
4900 * core.c: #include "command.h" for lint.
4903 * main.c: Remove some casts of enums. Lint.
4910 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4912 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4913 read it from memory. This will allow us to save ptrace calls
4914 eventually. Changed caller single_step too.
4916 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4917 that we aren't going to use, saving many ptrace calls, especially
4918 when watchpointing or single stepping. Use some #define's for
4920 (store_inferior_registers): Ditto.
4921 (core_file_command): Use some #define's for constants.
4923 * tm-sparc.h: Add #define's for some register numbers, so we
4924 can eliminate the use of random constants in sparc-xdep.c.
4926 * stack.c (frame_command, print_frame_info, up_command,
4927 down_command) Remove frame_changed, since it
4928 causes a bug and doesn't seem to do anything useful. In some
4929 places it was used as a flag, in others as a stack level (?).
4931 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4932 default is to use the portable (vprintf) version rather than the
4934 * xm-news.h (MISSING_VPRINTF): Add.
4936 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4938 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4940 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4941 about linking debugged programs -Bstatic in the sun?os4 config
4942 files in tconfig and xconfig subdirectories.
4944 * main.c (main): Remove unreached exit(0) now that we exit
4947 * Create TODO file for online bug list. There are too many
4948 "little" bugs to keep track of on paper.
4950 * Change Projects file to refer to bug-gdb@cygnus.com
4951 rather than kingdon@ai.
4953 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4955 * Makefile.dist (VERSION): 3.91.4 now.
4957 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4958 (condense_misc_bunches): Add sanity check that misc_count is
4959 the same as the number of symbols in the bunch.
4961 * coffread.c: rename init_misc_bunches. Pass an argument
4962 to condense_misc_bunches (a zero).
4964 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4965 every time we are called; don't rely on our caller to do it.
4966 (add_file): Remove call to init_misc_bunches.
4968 * mipsread.c: Only warn, don't error, if unknown symbol types.
4969 This keeps an old gdb from falling on its face if it sees newly
4970 extended symbol info. Rename init_misc_bunches.
4972 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4974 * Merge in changes from Per Bothner for DECstations and other
4975 MIPS stuff. The rest is Bothner speaking:
4977 The next message is a merger of Alessando Forin's mips port with
4978 mine. I've tried to use my good if biased judgment to get
4979 the best of both. It *does* need testing.
4981 Some of the changes are general, *not* mips-specific.
4984 Didn't believe in little-endian bit order.
4985 There are still inconsistencies about whether flags
4986 like BITS_BIG_ENDIAN are integer (#if ...) or
4987 boolean (#ifdef ...). I tried to paper over them.
4989 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4990 Moved some misc_function code that was common to
4991 {dbx,coff,mips}read.c to symtab.c.
4992 In the process, I think I cleaned things up a bit.
4993 At the same time, moved obsavestring and obconcat to symtab.c.
4996 Removed obsolete condense_addl_misc_bunches (use
4997 condense_misc_bunches(1) instead).
5000 Needed to include <sys/dir>, at least on DECstations.
5002 valops.c, mips-tdep.c, tm-mips.h:
5003 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5004 conventions (when STACK_ALIGN is insufficient).
5005 Needed on mips, where doubles need 8-byte alignment,
5006 but ints only need 4.
5009 Removed cruft that was not being used.
5010 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5013 Print $ before register-names (I think that makes things a little
5015 Never print two instructions, even if one delays.
5016 Removed hex-disassemble set_cmd. (This is not mips-specific,
5017 so I think the argument is whether it is generally worthwhile or not.
5018 I'm inclined to think not, given how easy it is to
5019 convert between radixes in gdb.)
5022 This is basically Alessando's code.
5023 It doesn't use obstacks; I changed it to use obstacks
5024 in a few minor places where using malloc causes a
5025 memory leak. (Probably, more places could/should be changed.)
5026 I added record_misc_function where it was missing.
5027 In symbol_file_command and add_file_command, I tried
5028 to make the code consistent with more recent versions.
5029 Minor sylistic changes in parse_procedure.
5030 Make a .gdbinfo. psuedo-symbol point back to the real
5031 procedure symbol (using the isym field).
5034 This is basically from my port, but with a lot of details
5035 and a number of routines merged in from Alessando's version.
5036 I basically used my code "raw" backtrace (use heuristics
5037 from the actual code, rather than symbol table info) - though
5038 the idea is Alessandro's. I feel my code is a little cleaner
5039 here, particularly in being a little more flexible, such as being
5040 able to handle gcc-produced code (which it now can).
5041 It also doesn't do frame caching (which is not useful
5042 more recent gdb versions).
5043 I also used my code for push_/pop_dummy, more or less.
5044 I tried to incorporate AF's code for testing sigtramp
5045 while backtracing; I probably got it wrong.
5046 Added mips_print_register, which tries to scrunch as much
5047 information as possible on a screen...
5048 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5049 under mips-pinsn.c), I don't see anything mips-specific here,
5050 and I don't see it being all that useful anyway.
5053 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5054 Use more register names (rather than hard-cases numbers).
5056 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5058 * Hack up 3.90.11 changes:
5060 * Makefile.dist (depend): parameterize $(GCC).
5061 Add solib.c and solib.o.
5062 (readline): Fix vpath for both absolute or relative SRCDIR.
5064 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5065 Also, let the part I didn't understand at least compile so
5066 I can test the rest. FIXME.
5068 * dbxread.c: Fix thinko using strcmp.
5069 (init_psymbol_list): declare static.
5070 (partial_symbol_file_open): Comment cleanups better, avoid
5071 cleaning up the string table since the caller will do that.
5072 Move the stat for mod time into symbol_file_command, temporarily.
5073 (There should be a mod time for each symbol file, eventually,
5074 to control its rereading. FIXME.)
5076 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5077 SunOS, which gives error for shared libs otherwise. (From
5078 Schaefer, probably FIXME needs work for portability.)
5080 * solib.c: Move #include "param.h" to work.
5081 Lowercase all the Uppercase Letters In the Messages.
5082 (find_solib): Clean up inferior_so_name for debug printouts.
5083 Allow no argument, to mean all shared libraries.
5085 * symmisc.c: include param.h to get CLEAR_SOLIB.
5087 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5089 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5090 to 3.90.11. ChangeLog entries below are from this.
5092 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5096 * Makefile.dist (HFILES): Add tm-sunos.h.
5098 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5102 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5104 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5106 * sparc-opcode.h Added single-operand version of rett.
5108 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5110 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5111 Put parens around gcc_p in expansion.
5113 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5115 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5117 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5119 * Changes for Sun shared libraries:
5120 blockframe.c (find_pc_partial_function): If a non-text symbol
5121 is found, set *address = pc - FUNCTION_START_OFFSET.
5122 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5123 Disable breakpoints instead of giving an error.
5124 source.c (select_source_symtab): Initialize cs_pst.
5125 symmisc.c: Call CLEAR_SOLIB if defined.
5126 symtab.h: Make text{low,high} CORE_ADDR not int.
5127 (psymtab): New field addr.
5129 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5130 (record_misc_function): Give correct type for N_DATA symbols.
5131 (condense_misc_bunches): do "misc_function_count = j" regardless
5133 Take code which is shared between symbol_file_command and
5134 add_file_command and put it into partial_symbol_file_{open,read}.
5135 Split add_file_command into add_file_command and add_file.
5136 Make psymtab_to_symtab read in the string table if the file
5138 Two new parameters to read_dbx_symtab and start_psymtab.
5139 tm-sunos.h: New file.
5141 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5143 * infcmd.c: Change cont_command to continue_command and "cont"
5146 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5148 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5150 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5152 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5153 size 1,2,4,8 rather than size < 8.
5155 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5156 as necessary, not just once.
5158 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5160 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5162 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5164 * tm-news.h: Add CALL_DUMMY_*.
5166 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5168 * config.gdb: In list_host, list_target, use ${i}, not $i.
5170 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5172 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5174 * sparc-opcode.h: Change all store floating-point state register
5175 instructions to have the right match & lose fields.
5177 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5179 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5181 config.gdb: If srcdir != ., create readline directory and
5182 copy a makefile into it.
5184 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5185 consistency with POSIX.
5187 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5188 when we exit its exp_valid_block.
5190 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5192 * Makefile.dist: Bump version to 3.91.3.
5194 * Clean up handling of breakpoint commands (somewhat).
5195 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5197 inferior.h: Add breakpoint_proceeded to inferior status struct
5198 and globals; save it and restore it.
5199 (clear_breakpoint_commands): Cleanup, remove old #define.
5201 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5202 (save_inferior_status, restore_inferior_status): handle it also.
5203 (proceed): Remove earlier code that set breakpoint_proceeded.
5204 It is now set only in clear_proceed_status.
5205 (clear_proceed_status): Cleanup, use bpstat_clear rather
5206 than clear_breakpoint_commands. No callers need the stop_bpstat
5207 between clear_proceed_status and proceed.
5209 infcmd.c: Add breakpoint_proceeded definition and comment.
5210 (cont_command, jump_command, signal_command): Move call to
5211 clear_proceed_status right next to call to proceed.
5213 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5214 caller's argument while running down the chain of breakpoints.
5215 Use new variable "breakpoint_proceeded" to determine when
5216 a command that it executes moves the inferior past the
5218 (bpstat_clear): Handle NULL argument.
5219 (bpstat_clear_actions): Avoid useless call to
5220 breakpoint_auto_delete.
5221 (delete_breakpoint): Clean up bpstat's that are pointing to
5222 the deleted breakpoint from the stop_bpstat chain.
5223 (breakpoint_auto_delete): Simplify.
5225 * Clean up handling of EOF, error on stdin, etc. This was
5226 prompted by a network problem that caused gdb to go into an
5227 infinite loop filling up its malloc'd memory.
5229 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5230 not clear_breakpoints_commands, which is now gone.
5231 (main): If command_loop returns (e.g. from EOF on stdin), do
5232 a quit_command (looping back to command_loop if quit_command
5233 doesn't really quit).
5234 (command_loop): check result from command_line_input and
5235 exit if it returns NULL, rather than passing the NULL to
5237 (gdb_readline): Free malloc'd result space before returning
5240 * utils.c (query): Handle C-d to mean "yes", just as if the
5241 input was not a terminal. Also avoid infinite loop if EOF
5242 occurs in mid-input-line before newline. This allows
5243 query to be used at EOF on stdin with reasonable results.
5245 * infrun.c (proceed): Set breakpoint_proceeded.
5247 * values.c (value_as_long): Avoid infinite recursion for enums.
5248 (_initialize_values): Fix typo in help msg (kingdon).
5250 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5251 RL_LIB for linking. This allows -lreadline for linking
5252 and nothing for dependencies, once readline is a real library.
5254 * config.gdb: Jim Kingdon: give useful error message if the
5255 host or target type is not recognized.
5257 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5258 it just defines it. Dumb, but deal with it.
5260 * Jim Kingdon suggests:
5261 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5263 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5265 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5267 * Clean up Bothner's changes.
5269 * blockframe.c (clear_pc_function_cache): New function.
5270 * blockframe.c: remake cache_pc_function_* static.
5271 * dbxread.c (symbol_file_command): remove references to
5272 cache_pc_function_* variables.
5273 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5274 * printcmd.c: Avoid kludging a global variable (addressprint)
5275 to avoid printing the address of a string twice. Instead,
5276 pass the format letter 's' down low enough that it can be seen
5277 to avoid this problem.
5278 (print_formatted): Pass format arg to value_print.
5279 (restore_addressprint): Remove function.
5280 (do_examine): Avoid hacking addressprint, cleanups and such.
5281 (print_frame_args): Add a comment to a Bothner change.
5282 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5283 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5284 to wipe out the values cached in blockframe.c.
5285 * symtab.c (find_method): Add comment saying how big you must
5286 allocate to be "big enough". Per being terse again.
5287 * valprint.c (val_print): Handle format letter "s" to print
5288 strings without addresses. Add comment to vtbl printing code
5289 which casts with wild abandon. Rearrange reference-printing
5291 @0xaddr: value (print w/addressprint)
5292 value (print w/~addressprint)
5293 @0xaddr (parameter lists w/addressprint)
5294 or nothing (parameter lists w/o addressprint)
5296 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5298 * Merge more changes from Per Bothner:
5300 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5301 annoying) that I tried to improve it. Here are my suggestions.
5303 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5306 Do automatic de-reference when taking the address of a reference.
5308 Don't deref_ref when printing parameter lists.
5310 More attempts at treating refernences properly.
5312 In val_print, if deref_ref==0, don't print dangling " = ".
5314 Add COERCE_REF macro, which de-references an REF.
5316 * Merge changes from Per Bothner:
5318 * Fixed (Sony news)-specific configuration problems.
5319 * Fixed other problems with using vanilla pcc and libc (enum problems;
5320 assumption that vsprintf exists).
5321 * Some major speed-ups (finc_pc_partial_function now caches a match;
5322 parsing avoids duplicate symbol_lookup calls).
5323 * Changed handling of baseclasses (no longer use baseclasses field
5324 of struct type, use the first n_baseclasses fields instead).
5325 * Various minor changes/fixes, most C++-related.
5328 Cache the most previous match from find_pc_partial_function.
5329 (Save both low and high ends of matching function's pc range.)
5330 This speeds up the loop of infrun.c:wait_for_inferior quite
5331 a bit, and makes step/next commands much zippier.
5333 Added an enum->int cast (otherwise, some compilers barf).
5335 No longer set baseclass offset to 0, since multiple
5336 inheritance now mostly works.
5337 Added a number of casts, to shut up compiler warnings
5338 (after stabs where made enums, not ints).
5339 When discarding a symbol table (in symbol_file_command),
5340 must clear the cache introduced in blockframe.c.
5341 Don't convert $vtbl_ptr_type to vtbl any more.
5342 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5343 Mask off sign bit emitted by g++ for virtual table offset.
5344 Set voffset to -1 (not 1) for static member functions.
5346 Changed parsing/lexing of names to avoid doing symbol lookup twice
5347 (once when lexing to determine symbol class, once for real).
5348 Now only call symbol_lookup once. Fields of 'this' win especially big.
5350 Subpress printing addr twice in the case of 'x/s addr'.
5352 lookup_basetype_type is no longer used.
5353 Add find_methods as recursive helper function to decode_line_1.
5354 This allows multiple inheritance to work.
5355 Also, once one or more matches has been found, do not look in
5356 base-classes. (Baseclass methods would be overridden, anyway.)
5358 Removed baseclasses array in struct type.
5359 Instead of using baseclasses[i], use fields[i-1].
5360 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5361 Changed sign convention of voffset (previous was inconsistent).
5363 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5365 Used to assume existence of vsprintf. Re-written to not need it
5366 if HAVE_VPRINTF is undefined.
5368 typecmp was too pessimistic. Made it less so.
5370 Don't print space after address.
5371 If vtable points to a misc symbol (with 0 offset), print it,
5372 since that indicates the actual class of the object.
5373 Changed ype_print_derivation_info to use new inheritance
5374 scheme (without baseclasses vector).
5376 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5377 Also, changes needed because TYPE_BASECLASSES were removed.
5379 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5381 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5384 If there is no path set, and the symbols don't indicate what directory
5385 a file was compiled in, look in the current directory. But either
5386 a path or a known compilation directory will prevent this.
5389 Three independent bug fixes:
5390 * Remove the #if 0 block that breaks some stuff.
5391 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5392 adapt gdb to either SunOS 4.0.* or 4.1.
5393 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5396 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5399 (type_print) Demangle the name being printed.
5400 (type_print_base) Handle botched demangling without coredump (tiemann).
5403 (check_stub_method): Document routine.
5404 (tiemann) fix bug for no-arg functions
5405 Avoid clobbering beyond end of malloc'd storage.
5406 Terminate the argument list properly.
5408 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5410 * Changes merged by John Gilmore:
5413 In breakpoint_1, use new print_address_symbolic instead
5414 of find_pc_partial_function. (This forces use of assembler-level
5415 addresses, and avoids misleading non-mangled source-level names.)
5417 Generalize ansi argument such that -1 means skip arglist totally.
5418 Removed global variable print_ansi_qualifiers (which made
5419 code non-reentrant), in favor of extra explicit arguments
5420 to internal routines.
5422 Add new helper function print_address_symbolic.
5423 Use find_pc_misc_function instead of find_pc_partial_function
5424 (since we want assembler-level symbols here).
5426 Print unknown function as just "f (...)", not "f (...) (...)".
5427 Use new fputs_demangled explicitly.
5429 Fixed a typing violation (problem: value.h cannot be imported
5430 without renaming many variable in this file).
5431 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5432 decode_line_1: Moved forward some never-reached code.
5433 Made decode_line_2 skip function prologues correctly.
5435 fputs_filtered should not demangle by default.
5436 Add new fputs_demangled to demangle on demand..
5438 Change value_struct_elt to use value_primitive_field (using recursive
5439 utility function search_struct_field). This allows foo.bar to work
5440 for multiple inheritance (so far only for data fields).
5441 Change check_field in the same way (recursive helper function
5442 to support multiple inheritance).
5443 (Note: there are more of these problems that I haven't fixed.
5444 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5445 value_of_this: 'this' symbol name is now just "this", note "$this".
5447 Don't print static members.
5448 Avoid printing "members of <type>" if there are none.
5449 Simplified type_print_derivation_info by merging duplicate code.
5450 Remove useless blank lines in type_print_base (ptype command).
5452 Added declaration of new routine value_primitive_field.
5454 Added value_primitive_field which is generalized version of
5455 value_field that can handle multiple inheritance (non-zero offsets etc).
5456 Re-implemented value_field to call value_primitive_field.
5458 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5460 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5461 delete the whole environment. Karl Berry reported the bug.
5462 * source.c - fix openp to avoid //'s in filenames, which
5463 trigger an Emacs bug causing it to not be able to find files
5464 when running gdb in a window.
5465 * dbxread.c - zap the #if 0 that botches the add-file code.
5466 It seems to work a lot better without all the code commented out.

5475 * Makefile - added a ${CFLAGS} to a couple of entries,
5476 added remote-sa.sparc.c
5477 * added remote.sa-sparc.c, a modification of remote.c
5478 which conducts a dialog directly with the SparcStation prom.

5480 remote_insert_breakpoint(), and remote_remove_breakpoint()
5481 to breakpoint.c instead of directly writing breakpoint instructions.
