3 Mainly stuff to improve handling of TYPE_CODE_REF values.
4 * valops.c (value_addr): If taking the addres of a
5 TYPE_CODE_REF, just cast the object to the corresponding
6 TYPE_CODE_PTR. This yields correct C++ semantics, and
7 preserves the location information, which has the nice effect
8 that &(&R) given the location containing R.
9 * values.c (value_copy): Make non-static (used by value_addr).
10 * eval.c (evaluate_subexp_for_address): Use the default
11 scheme (with value_addr) for a variable if it has TYPE_CODE_REF.
12 * valops.c (value_addr), eval.c (evaluate_subexp_for_address,
13 evaluate_subexp_with_coercion): Factor out some common
14 expressions into variables, for easier reading.
15 * findvar.c (locate_var_value): Remove code to handle
16 TYPE_CODE_REF - it should no longer be needed.
17 * valops.c (value_assign): Do a COERCE_REF on the
18 destination operand, for correct C++ semantics.
19 * valarith.c (value_x_binop): Ditto: De-reference C++
20 references in the arguments.
21 * valops.c: ANSI-fy: bcopy->memcpy, bzero->memset.
23 Sat Dec 28 11:30:26 1991 Per Bothner (bothner at cygnus.com)
25 * dwarfread.c, coffread.c: Use INIT_CPLUS_SPECIFIC.
26 * symtab.c (gdb_mangle_name): Recognize and handle
27 constructors specially.
28 * symtab.c (check_stub_method): Test for failure from
29 cplus-demangle by calling error() instead of seg-faulting ...
31 Fri Dec 27 22:21:30 1991 Fred Fish (fnf at cygnus.com)
33 * defs.h: Add definition of null_cleanup()
35 * procfs.c: Many small changes to add base support for a new
36 "info proc" command (currently only printing of the address
37 space mapping is implemented) and allow iteration over the
38 address space mapping, calling an arbitrary function for each
39 mapping (used for shared library support).
41 * solib.c: Change all ifdefs that checked for "sun" to check
42 for "!SVR4_SHARED_LIBS" instead. Rewrite lookup_base() to
43 handle locating the debug base address even when not currently
44 stopped at the dynamic linker entry point.
46 * utils.c: Add null_cleanup() as a known function that does
47 nothing to serve as a base for possibly long cleanup chains
48 with no specific "first cleanup" to serve as an anchor.
50 * xm-sysv4.h: Add define of SVR4_SHARED_LIBS
52 Fri Dec 27 10:11:33 1991 Per Bothner (bothner at cygnus.com)
54 * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
55 pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
56 these are all essentially the same as the versions
57 in ../include/opcode. The remaining *-opcode.h here
58 are not quite so obviously the same, and need study.
59 * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
60 tahoe-pinsn.c, vax-pinsn.c: Change so these include
61 opcode/FOO.h (actually ../include/opcode/FOO.h)
62 instead of the recenntly departed opcode-FOO.h files.
63 * sparc-pinsn.c: Now that we're using the much tighter
64 opcode table in ../include/opcode/sparc.h, we shouldn't
65 need to sort the opcodes before dis-assembly.
67 * symtab.h, symmisc.c: Make cplus_struct_default be const.
68 * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
69 * symmisc.c: Remove unused 'nfields' variable.
70 * buildsym.h: Add extern decl of unknown_symtype_complaint,
71 since it used used by partial-stab.h (included two places).
72 * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
73 we should never hit the default case (until new stab codes
74 are added). Hence, we can leave the complaint in the
75 default case in even when DBXREAD_ONLY is off.
76 * partial_stab.h: Recognize a pair of N_SO stabs (one for the
77 directory, one for the filename proper) without peeking ahead.
78 * dbxread.c, mipsread.c: Because of previous change, don't need
79 ugly CHECK_SECOND_N_SO macro.
80 * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
81 macro that invokes a function pointer in next_symbol_text_func.
82 * mipsread.c: Added comments various places to
83 explain what is going on.
84 * mipsread.c (parse_symbol): Support the new (SGI-specific?)
85 symbol types stStruct, stUnion, and stEnum.
86 Also, some fixes in the code for dealing with tags.
87 * mipsread.c: Change handling of startup_file_start and _end
88 - now just use the textlow and texhigh of a psymtab
89 to check if we've found the startup-file.
90 * mipsread.c: Replace s_idx by global cur_sdx in many places.
91 This is so mips_next_symbol_text can get at it.
93 Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
95 * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
96 dbxread.c to symmisc and change name to add_psymbol_to_list.
97 Ditto for add_psymbol_addr_to_plist(). Also expand their
98 body to not use ADD_PSYMBOL_VT_TO_LIST.
100 * dwarfread.c: Remove add_psymbol_to_list() and convert usages
101 to the ADD_PSYMBOL_TO_LIST macro.
103 * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
104 to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
106 * partial-stab.h, symfile.h: Move definitions of the macros
107 ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
108 partial-stab.h to symfile.h. They aren't stab specific.
109 Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
111 Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
113 * Makefile.in: Roll VERSION to 4.3.2.
115 Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
117 * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
118 * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
119 Include <opcode/FOO.h> instead of <FOO-opcode.h>.
121 * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
122 dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
123 allocated when it is needed. Until it is needed, it points
124 to a shared statically allocated structure.
126 * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
127 in read_ofile_symtab to recognize two initial N_SO stabs,
128 and let process_on_symbol handle it. This is cleaner, more
129 efficient, and lets mipsread.c share the same code.
131 * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
132 and related macros to here ...
133 * dbxread.c: ... from here.
134 * symmisc.c: Move the "overflow" handling from
135 ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
136 * dwarfread.c: Re-write add_psymbol_to_list to use
137 ADD_PSYMBOL_VT_TO_LIST macro.
139 * mipsread.c: Extend mipsread.c to handle stabs-style symbols
140 encapsulated in ecoff symbols. This enable full g++ debugging.
141 * partial-stab.h: Move the code for pre-scanning symbols
142 and building psymtabs to an include file, out from dbxread.c.
143 This way, the same code can also be used by mipsread.c.
144 * dbxread.c, buildsym.h: Various changes to allow some functions
145 to be used by mipsread.c (also some arguable stylistic changes).
147 * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
148 since mips-tfile puts relocatable addresses into LBRAC/RBRAC
151 * mipsread.c: Replace code to handle ambiguous tag blocks.
152 Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
153 at types and offsets) if a tag is a struct, union, or enum.
154 Still patch it later if we find out for sure.
155 * mipsread.c: In various ways, replace Forin's
156 ideo-syncratic code by code that fits better with the
157 rest of gdb, for both stabs-based and ecoff-based symtabs.
158 E.g. use end_psymtab; don't do extra passes over FDR table to
159 pre-partition global data; don't use external symbols to
160 create static/global symbols (just put them in the
161 misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
162 sort psymtabs or symtabs; use obstacks more.
164 * symtab.c, mipsread.c, dbxread.c, buildsym.c:
165 ANSIfy: Replace bcopy by memcpy, bzero by memset.
167 Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
169 * solib.c (locate_base): Fix uninitialized variable that was
170 causing return of random value to callee.
172 * config/mh-amix, config/mh-i386v4: Change to find alloca by
173 compiling and linking alloca.c, even when it is not strictly
174 required. Also arrange to link with -ltermlib rather than
177 * Makefile.in: Move TERMCAP definition to prior to inclusion
178 of host makefile fragments so it can be overridden.
180 Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
182 * xcoffread.c (read_symbol_lineno): Logic error in incrementing
183 symbol table entry number. (From Metin Ozisik.)
185 Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
187 * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
188 so compiles with native compilers (without builtin alloca) can
189 pick up the version from the bsd emulation library. However, we
190 search the standard C library first so we don't pick up lots of
191 other broken stuff from libucb.a, that we *don't* want.
193 * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
194 Change svr4 references to sysv4.
196 * source.c: Move declaration of external function index to
197 front of file so it is in scope for all references.
199 * utils.c (error, fatal): Make definitions consistent with
200 defs.h declarations (declared as "volatile void").
202 Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
204 * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
206 Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
208 * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
209 sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
210 vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
212 Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
214 * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
215 for these SVR4 systems.
217 * symfile.c (symbol_file_add): When verbose is set, print
218 the names of files from which symbols are being loaded, as
219 when from_tty is true.
221 * solib.c: Completely reorganized (rewritten) to support
222 SVR4 shared libraries in a manner very close to the original
223 SunOS implementation. This support is expected to change and
224 become more general at some future time. The SVR4 version
225 does not yet work for attached processes, for example.
227 * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
228 relocation address to be valid whether or not symbols are
229 being read from a shared library or an executable. Use the
230 relocation address recorded in the psymtab when reading
231 full symbol tables (in read_ofile_symtab). Ensure that the
232 relocated address ranges are recorded in partial symtabs.
234 * elfread.c: Add new function elf_interpreter() to return the
235 string from the ELF ".interp" section. This is the interpreter
236 that the kernel tries to run and feed the executable to.
237 Expand arguments to record_misc_function to include a type arg.
238 Modify elf_symtab_read() to supply the type arg, and to do symbol
239 relocations for symbols read in from shared libraries.
241 * procfs.c: Add new functions proc_base_address() and
242 proc_address_to_fd(), used by shared library support.
244 * tm-svr4.h: Add macros to support SVR4 shared libraries.
245 Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
246 CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
248 Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
250 * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
251 unused START_INFERIOR_HOOK.
253 * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
254 to account for slow loading from floppies.
255 (eb_create_inferior): New fn, from eb_start and
256 nindy_create_inferior.
257 (eb_close): Only use log_file if nonzero.
258 (eb_xfer_inferior_memory): If not writing, then read!
259 (eb_read_inferior_memory, eb_write_inferior_memory): Return length.
260 (eb_kill): A new no-op.
261 (eb_mourn_inferior): Remove breakpoints, then generically weep.
263 Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
265 * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
266 miscellaneous comparisons of integer with NULL that elicit
267 compiler warnings about comparison of integer with pointer, when
268 NULL is ((void *) 0) rather than just a bare 0.
270 Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
272 * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
273 while we reset it, in case of problems. Print breakpoint number
276 * buildsym.c (read_struct_type): Avoid sun3 compiler bug with
279 * source.c (find_source_lines): If getting file mod time fails,
282 * target.c (target_xfer_memory): If errno is set, return it,
285 Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
287 * Makefile.in: infodir belongs in datadir.
289 Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
291 * symtab.h (struct fn_field): Add new fields `is_private',
292 `is_protected', `is_stub', making room by reducing the size of
294 (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
295 and `protected_fn_field_bits'.
296 (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
297 (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
298 (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
299 (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
300 * valops.c, valprint.c, symtab.c: All callers updated.
302 * buildsym.c (read_struct_type): Delete the `visibility' field
303 from `struct next_fnfield', and rework code so that visibility
304 info is stored into the fn_field directly. Also, hacked to set
305 TYPE_FN_FIELD_STUB for both static and normal member functions.
307 Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
309 * i386-tdep.c: Fix a problem on i386 systems where buffered code
310 stream access was failing to take into account the minimum size
311 granularity of the code section. For now, the buffering is simply
312 disabled. There is a similar problem in the i386 disassember code
313 that has not yet been fixed (FIXME).
315 * gmalloc.c: Use macros to hide some of the ugly casting required
316 in the previously applied fix for pointers with high bits set.
318 Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
320 * Makefile.in: Roll VERSION to 4.3.1.
322 Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
326 * Makefile.in: Roll VERSION to 4.3
327 * README, TODO, WHATS.NEW, depend: Update.
329 * inflow.c (terminal_inferior): Avoid error msg if attached.
331 * gmalloc.c: Fix bug that causes malloc & free to
332 fail on systems where pointers have the high bit set (0x800efcf0
333 for example). The problem is that the difference between two
334 pointers is a signed integer, so the computation
336 (char *) 0x800efcf0 - (char *) 0
338 yields a negative value. The sign of the result of the modulus
339 operator is machine dependent for negative operands, thus it is
340 possible for it to end up negative. From Fred Fish.
342 Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
344 * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
345 added clean-info. added some standards.text support and made it
346 look like our other Makefiles.
348 * configure.in: mark this directory target dependent. configure
349 now runs entirely in objdir so make existence tests and
350 references against ${srcdir}.
352 Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
354 * dwarfread.c (enum_type, struct_type): Fixes for opaque and
355 anonymous enumerations, structures, and unions. Now passes all
356 the current gdb test suite tests.
358 Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
360 * Makefile.in: idestdir and ddestdir go away. Added copyrights
361 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
362 and mandir now keyed off datadir by default.
364 Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
366 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
367 mid-line, be more careful about possibly advancing to the next line.
369 Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
371 * cplus-dem.c (cplus_demangle): Call `string_need' when
372 null-terminating a partially-computed string.
374 Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
376 * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
377 symbol to the symbol table for each member of the enum.
379 * dwarfread.c (struct_type): Build a correct TYPE_NAME.
381 * dwarfread.c (add_enum_psymbol): New function to extract enum
382 member names and add them to the partial symbol table while
383 building partial symbol tables.
385 Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
387 * symtab.c (check_stub_method): Must allocate two extra argument
388 slots (one for `this', one for arglist terminator).
390 Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
392 * inflow.c (child_terminal_info): Supply missing '"' character.
394 * buildsym.c (define_symbol): Supply missing parenthesis.
396 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
398 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
399 Jay Lepreau <lepreau@cs.utah.edu>.
401 * inflow.c: Remember whether GDB has a terminal. Avoid switching
402 terminals back and forth if we don't have one.
404 * c-exp.y (parse_number): Zero is not an unsigned int constant!
405 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
407 Improve type parsing.
408 * buildsym.c (define_symbol, read_range_type): Add
409 long_kludge_name that passes the names of range types being
410 defined, down to where we must choose between 'int' and 'long'
411 variants. This fails on Sun C anyway since the compiler itself is
412 confused between int and long.
413 (read_array_type, cleanup_undefined_types): Correct the size of
414 array type whose element-type size isn't immediately known.
416 Early preparation to blow away many builtin types, building them
417 on the fly as needed. Don't compare types to builtin types with
418 ==; examine the relevant fields instead.
419 * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
420 * buildsym.c (define_symbol, case 'p'): Avoid ==.
421 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
422 target types are the same.
423 * valprint.c (val_print): I finally understand arrays, remove FIXME.
425 * symmisc.c (printpsyms_command): Reduce redundancy, and put all
426 addresses in GDB itself into parens for easy cleanup and diffing.
428 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
430 * dwarfread (enum_type): Arrange for the order of enumeration
431 members to match the source code order; not the order in the
432 Dwarf information, which is explicitly reverse order.
434 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
436 * main.c (input_from_terminal_p): Check whether GDB has a
438 (initialize_main): Revise doc for `set editing'.
440 Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
442 * dwarfread.c (struct_type): Handle structures and unions which
443 contain DIE's other than just member dies.
445 Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)
447 * symfile.c (reread_symbols): Avoid kludging mtime_set, now that
450 Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
452 * Makefile.in: VERSION 4.2.96.
454 * main.c (initialize_main): Revise command descriptions.
455 * command.c (show_user): `info user' -> `show user'.
456 * symtab.c (_initialize_symtab): Typo in `info types' desc.
458 * coffread.c (coff_symfile_read): Avoid select_source_symtab,
459 since it is not needed and can cause errors when examining ".o"s.
460 (read_coff_symtab, decode_base_type): Use complain, not printf.
461 Print symbol name, not its number.
462 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
463 someday should go in a clipper target config file.
465 * symfile.c (compact_misc_function_vector): Handle empty vector.
466 (complain, clear_complaints, syms_from_objfile): Fix complaint
468 * xcoffexec.c: Change syms_from_objfile caller.
470 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
471 when configured for cross debugging. FIXME, this needs a more
474 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
476 * mips-tdep.c (init_extra_frame_info): Float register
477 'i' has gdb-internal number 'FP0+i', not '32+i'.
478 * mipsread.c (new_symbol): Translate g++ special
479 symbol "$t" to "this".
481 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)
482 Changes due to include file renaming:
484 * xcoffread.c: internalcoff.h ->coff/internal.c,
485 coff-rs6000.h ->coff/rs6000.h
486 * mipsread.c: coff-mips.h ->coff/mips.h
487 * elfread.c: elf-common.h ->elf/common.h
488 elf-external.h ->elf/external.h,
489 elf-internal.h ->elf/internal.h

491 * dbxread.c: aout64.h ->aout/aout64.h
492 stab.gnu.h ->aout/stab_gnu.h
494 * coffread.c: internalcoff.h ->coff/internal.h
495 * buildsym.c: stab.gnu.h ->aout/stab_gnu.h

505 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
506 DECR_PC_AFTER_BREAK to be predefined by files including
509 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
510 supply_fpregset(), and fill_fpregset() functions, which are
511 target dependent support functions for the SVR4 /proc register
514 * dwarfread.c (enum_type, struct_type): Expand recognized
515 compiler generated tags to include symbols beginning with '.' as
518 * symtab.c (sources_info): Change simple printf of error message

529 Fix bugs in C++ debugging.
531 * symtab.h: target_type is not used in record types.
532 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
533 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
535 * symtab.c (lookup_member_type): Don't chain them up, just
536 allocate one in symbol_obstack when we need one.
537 (allocate_stub_method): Build stub in symbol_obstack.
538 (check_stub_method): Move here from values.c. Don't deallocate

543 Change some C++ parsing error()s to complain()ts.
544 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
545 structs have the same representation and work the same as far as
547 * buildsym.c, symtab.c, values.c: Remove all references to
548 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
550 * valops.c: Improve comments and indentation. Only call
551 check_stub_method when the stub flag is on.
552 * valprint.c: Fix or mark minor bugs and unportabilities.
554 * coffread.c (anonymous unions): Allocate a cplus structure.
556 * mipsread.c: Eliminate "template" types. Build new, real
557 types whenever we need them. Allocate cplus structures as needed.
558 Bulletproof the type parsing a bit more. Mark storage leaks.
559 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
560 on top of a partial type.
562 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)

565 print a message if any of them fail.
566 (terminal_ours_1): Store result of ioctl's for debugging, but
567 don't print (the terminal isn't ours...).
569 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
572 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
573 conflicts with system header files.
575 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
577 * Roll VERSION to 4.2.95.
579 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
580 first, before defs.h.
581 * config/mh-i386sco: Override compiler to gcc, print warning.
582 * configure.in: Handle i386-none-aout rather than i386-aout-none.
583 * infptrace.c, language.h, utils.c: Lint.
584 * m2-exp.y: #undef MAX and MIN in case system includes set them.
585 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
586 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
587 redefinition warnings.
588 * defs.h: Reorder things so that the xm-file gets first crack
589 at #define's, followed by defs.h and then the tm-file.
590 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
591 Late-model BSD 'make's don't cope with them.

597 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
599 * dwarfread.c (struct_type): Must initialize the c++ specific
600 portion of union types as well as struct types, since gdb attempts

627 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
629 * Remove gdb/hp-include. Support for HP a.out oddities should be
630 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
632 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
634 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
635 Makefile fragments for various hosts and targets now come from
636 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
639 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
640 * rs6k-opcode.def: Delete.
642 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
644 * dwarfread.c: Recognize obsolete form of AT_element_list
645 attribute still used by at least one AT&T compiler, and possibly
648 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
650 * dwarfread.c (enum_type, struct_type): Ignore names invented by
651 helpful compilers for anonymous structs, unions, and enums.
653 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
654 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
655 can coexist in the same executable without collision.
657 * symtab.h: Add declaration for lookup_template_type() to kill
658 compiler warnings about conversions from int to pointer.
660 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
662 * procfs.c: Move inclusion of defs.h to before param.h, as in
663 all the other source files that include both. This is required
664 to supply some typedefs that are used in files included by param.h.
666 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
667 skipping function prologues, ala the other cpu families (i386,
668 mips, m88k, etc). Add the ability to skip movm and fmovm
669 instructions in the prologues. Still needs support for profile
670 (-p compiled) prologue sequences (FIXME).
672 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
673 m68k prologue skipping function by default.
675 * tm-altos.h, tm-isi.h: Continue to use the old definition of

685 of defaultable things.
686 * tm-m88k.h: New file, common to all Moto 88k target configs.
687 Derived from tm-delta88.h.

697 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
699 * source.c (open_source_file): If openp fails, try again
700 using just the base (non-directory) part of the filename.
701 This solves various annoying problems, such as when the
702 source was compiled with an absolute pathname - and the
703 source files have moved. Or if the source was compiled
704 using a relative pathname, it can be more convenient
705 to just specific the source directory to the dir command.
707 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
709 * cplus-dem.c (munge_function_name): Add missing third arg to
710 instance of call to do_type().

722 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
723 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
725 (read_struct_type): Ditto. Also, add comments about how we can
726 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
727 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
729 (read_struct_type): Ditto.

748 * symfile.c: Add function compact_misc_function_vector() to
749 remove duplicate misc function vector entries. See comments
750 in source for why this is necessary/desirable.
752 * dwarfread.c: Add misc function type parameter to internal
753 record_misc_function(). Remove calls to init_misc_bunches()
754 and condense_misc_bunches(), these are now done in elfread.c.
756 * elfread.c: Add support for reading bfd canonical symbol tables
757 and generating misc function vector entries for global and
758 absolute symbols. Do calls to init_misc_bunches() and
759 condense_misc_bunches() where they will enclose all calls to
760 record_misc_function(), including those in dwarfread.c.
762 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
764 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
765 (roffable documentation).
766 * doc/gdb.texinfo: embedded hints (as comments) for better
767 texi2roff conversion.

783 Motorola 88000 port without tears, I mean without tdescs.
785 * m88k-tdep.c: Blow away all tdesc stuff.
786 Provide functions for all the frame-related macros in
787 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.

789 from i960-tdep.c and adapt to the function prologues on the 88k.
790 (read_next_frame_reg): Borrow from mips-tdep.c.
791 FIXME: frame_locals_address should go away.
793 * tm-delta88.h: Dump all the tdesc stuff.
794 Macros for all frame-related stuff call fns of same name.
795 Remove duplicated definitions. FP_REGNUM becomes same as
798 * xm-88k.h: Eliminate lots of library dependencies, now handled
799 in libiberty. Eliminate KDB nonsupport.
801 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.

827 flags since they are no longer used.
829 Fixes to support C++ methods with functional parameters.
830 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
831 types in a function type.
832 * eval.c (parse_and_eval_type), value.h: New function,
833 parse_and_eval_type, is based on old code from check_stub_method.
834 But don't actually evaluate the cast, since that calls
835 value_cast(), whcih may fail. Just extract the type
836 from the parsed expression.
837 * values.c (check_stub_method): While looping through the
838 arguments, adjust depth *after* parameter has been handled.
839 Replace call and setup of parse_and_eval with new function

882 whenever it is not supplied by coredep.c
884 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
886 Add tracking of object files (that contain symbols) to gdb.
887 This includes a "struct objfile" that owns symtabs and psymtabs
888 that were read in from that binary file.
890 * symfile.h: Add struct objfile. Add pointer to the objfile
891 into the struct sym_fns.
892 Replace global `symfile' and `symfile_mtime' with

963 * symfile.h, symfile.c, symtab.h: Lint
965 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)

978 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
979 struct for BCS 88k machines.
980 * xm-m88k.h: don't define USIZE if already defined.

991 function calling code moved to m68k-tdep.c.
993 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
995 * coffread.c: Eliminate c_nsyms in favor of c_naux.
996 Complain if no auxents on .bf and .ef FCN symbols, and assume
997 lots of line numbers.
998 (init_linenos, enter_linenos): Use a sentinel at the end of the
999 read-in linenos, to make for a fast, safe loop-end test.
1001 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
1003 * coffread.c (read_coff_symtab): coffread used to rely on the
1004 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
1005 function. Two of the formats I'm using (29k and 88k) don't seem to
1006 set it. Ths patch to fcn_last_line and (enter_linenos) is an
1007 attempt to use the actual size of the linno table in the file to set
1008 the number of linenos to process.
1010 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
1012 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
1013 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
1014 are created in place, so the mv fails, then the make continues.
1016 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
1018 Add C++ as a separate language.
1019 * defs.h (enum language): Add language_cplus.
1020 * dwarfread.c (end_symtab): Support language_cplus.
1021 * c-exp.y: Add new struct language_defn cplus_language_defn.
1022 Don't set c to be the default language (see main.c).
1023 * c-exp.y (yylex): Only look for field of this if
1024 language is C++. (First difference from C!)
1025 * language.c: Add case branches for C++ (currently, all
1026 the same as C). Also, add c++ to "usage" note for "set lang".
1027 * valprint.c (typedef_print). Add case branches for C++.
1028 * main.c (main): New way to set initial language: Look at
1029 file extension of psymtab containing main(). (Same as we
1030 do for symtabs, but avoid loading the symtab yet.)
1031 * symtab.c: New routine find_main_psymtab(), used by main()
1032 to set initial language.
1033 * symfile.c (allocate_symtab): Move code for mapping file
1034 extensions-> languages to new deduce_language_from_filename().
1036 Fix a C++ problem when looking for methods in super-classes.
1037 There was confusion between base and derived types.
1038 * valops.c (value_fn_field): Change function interface.
1039 * values.c: Use new value_fn_field interface.
1041 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
1043 * infrun.c: Fixed typo in comment.
1044 * utils.c: All the v*fprintf emulation is now in libiberty,
1045 so we can get rid of some junk.
1046 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
1047 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
1048 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
1049 type operands, as used by branch instructions.
1050 * gmalloc.c: Fix prototype of memcpy.
1051 * elfread.c: Comment out register_addr, since it conflicts
1052 with the one in coredep.c.
1053 * buildsym.h: Remove extern declarations of two functions
1054 that are really static in buildsym.c.
1055 * tm-mips.h: Add symbolic names for more registers.
1056 * mips-xdep.c (store_inferior_registers): Use new register names.
1057 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
1058 only used for core files, not ptrace. Therefore,
1059 the KERNEL_U_ADDR hack is no longer needed.
1060 The mapping to ptrace number is now in in mips-xdep.c.
1061 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
1062 mapping from the old REGISTER_U_ADDR), and use it
1063 in {fetch,store}_inferior_registers.
1064 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
1065 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
1066 Save/restore FP regs correctly (?).
1067 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
1068 (these had been previously moved to buildsym.c).
1069 Hence, define_symbol becomes extern instead of static.
1070 * buildsym.c (read_struct_type): Comment out bogus handling
1071 of C++ operator methods. Minor hacking of reading of class
1072 contexts. Make define_symbol non-static, so dbxread.c can call it.
1074 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
1076 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
1077 filename with error messages.
1078 * stack.c (frame_select_command): Rename to select_frame_command
1079 to avoid "fr" and "fra" having nonunique completions.
1080 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
1081 (symfile_init): Print file format name when unable to handle it.
1082 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
1083 * symmisc.c (free_symtab): Only free linetable if nonzero.
1084 * symtab.h: Remove obsolete BLOCKLIST macros.
1086 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
1088 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
1089 that stop_step is 1 at bottom of main loop. I don't know why this
1090 needs to be done, but it helps me sleep better at night.
1092 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
1094 * main.c (initialize_history): Read history after reading all
1097 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
1099 * buildsym.c: Break out initial malloc sizes.
1100 (record_line): Record directly in a subfile. Alloc on demand.
1101 (compare_line_numbers): Add from xcoffread.c.
1102 (end_symtab): New params say whether to sort pendings and
1103 linetable. Patch block stabs if defined. Shrink linetable before
1104 allocating the symtab.
1105 * buildsym.h: Delete line_vector* and prev_line_number. Add
1106 global_stabs and file_stabs for xcoffread.
1107 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
1108 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
1109 * symmisc.c, symtab.c: Cope with null LINETABLEs.
1111 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
1112 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
1113 tm-sparc.h: Accept fromleaf parameter.
1114 * c-exp.y (yyerror): Pass error message if given.
1115 * configure.in: Add rs6000 host and target.
1116 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
1117 * symfile.h (entry_point): Add.
1119 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
1121 * buildsym.c: New file. Breaks out symbol-table-building routines
1122 from dbxread.c, so they can be shared with xcoffread.c.
1123 * buildsym.h: New file. Declarations for buildsym.c users.
1124 * dbxread.c: Remove large chunks into buildsym.c.
1125 * Makefile.in: Add buildsym.c and buildsym.h.
1127 * symfile.c (syms_from_bfd): New routine.
1128 (add_symbol_file): Call it to do the real work.
1129 (syms_from_bfd): Initialize entry_point before calling symfile_init.
1130 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
1131 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
1133 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
1135 * cplus-dem.c (cplus-demangle): added support for templates, static
1136 data, and the new (correct) mangling for destructors.
1138 * dwarfread.c: (dwarfwarn): created a varargs version of
1139 dwarfwarn, for non __STDC__ compilers.
1141 * c-exp.y: (yylex): added match for "template" token.
1142 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
1143 specification of template types.
1145 * symtab.c: (lookup_template_type): new function for finding
1146 templates in symbol table.
1147 (type_name_no_tag): changed to explicitly check for s/u/e at the
1148 beginning of the symbol - if it is a template, none of these will
1149 be there (but the name will still contain spaces.)
1151 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
1153 Various fixes to improve g++ debugging.
1154 * symtab.h: Add is_const and is_volatile flags for each method.
1155 These are bit fields - take their space from voffset,
1156 which shrinks to 30 bits. Since voffset is now a bitfield,
1157 make it unsigned for portability. This changes its interpretation
1158 slightly: Static methods now have voffset 1 instead of -1,
1159 and virtual offsets start at 2, not 1.
1160 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
1161 since it now returns an entire magled method name, not just
1162 the type part. This avoids some duplication.
1163 It also allows us to correctly mangle const and volatile
1164 methods (using the new is_const and is_volatile bit fields
1166 * valprint.c (type_print_base), values.c (check_stub_method):
1167 Simplify by using new gdb_mangle_name.
1168 * values.c (value_headof): Fix to correctly handle single
1169 inheritance (actually two fixes, either of which suffices).
1170 * dbxread.c (read_struct_type): Handle const and volatile
1172 * dbxread.c (read_struct_type): Yet one more place where
1173 we must handle '\\' continuations.
1174 * valprint.c (vtbl_ptr_name): Add final '\0'.
1176 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
1178 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
1179 short return values for sparc and 68k. Patch from Paul Eggert.
1181 * coffread.c, coredep.c, i386-xdep.c: install patches for
1182 SysV/386 3.2 from Mauro DePalma.
1184 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
1186 * core.c (core_file_info), exec.c (exec_file_info): Print file
1187 type. Use printf_filtered.
1189 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
1191 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
1193 * dwarfread.c: Add casts to remove compiler warnings.
1195 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
1196 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
1197 tm-sun3.h: Remove locally duplicated code for calling functions
1198 in the inferior. The only differences were in the specific trap
1199 vectors used and whether or not an fpu was present. These are
1200 now handled by appropriate definitions of BPT_VECTOR and
1201 HAVE_68881 respectively. Other minor obvious cleanups.
1203 * valops.c: Correct a minor misspelling.
1205 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
1207 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
1210 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
1212 * stack.c (frame_command): Always print. Use new
1213 frame_select_command to select a frame without printing.
1215 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
1217 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
1219 * dwarfread.c: New file for DWARF debugging format support.
1221 * elfread.c: New file for ELF object file format support.
1223 * procfs.c: New file for SVR4 /proc (process file system) support.
1225 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1228 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1230 * xm-m68k.h: New file for host machines with m68k cpu.
1232 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1233 Add elfread.o and dwarfread.o to OBS.
1235 * symfile.h: Add "elf" to list of supported formats in comment.
1237 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
1238 types to gdb, builtin_type_long_double, builtin_type_complex, and
1239 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
1240 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1241 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1242 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1243 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1245 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
1246 call proc_set_exec_trap() to setup child to stop at first instruction.
1248 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
1251 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1252 supply_fpregset(), and fill_fpregset(), which are machine
1253 dependent support routines for SVR4 /proc interface.
1255 * utils.c: Add warning_setup() and warning(). Warning() behaves
1256 the same as error() except that it returns normally rather than
1257 jumping back to command level. Modules that don't want to call
1258 warning() for some reason, but want to produce their own warnings,
1259 can call warning_setup() to ensure compatibility with the way
1260 warning() and error() deal with the terminal.
1262 * symtab.c: Make internal errors produce more useful messages.
1264 * tm-68k.h: Move code that is duplicated in almost every single
1265 m68k based machine's configuration files to this common file.
1266 Duplications in the configuration files still need to be removed
1269 * infrun.c (child_create_inferior): System V versions must call
1270 setpgrp() with no arguments, to comply with prototyping typically
1273 * munch: Add support for SVR4 style nm output.
1275 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
1276 file specific fields from the partial symbol table structure and
1277 replace them with a pointer to private data for each different
1278 flavor of object file reader to initialize appropriately.
1280 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
1282 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
1285 * mipsread.c (fixup_undef_type): New function. If a struct /
1286 union / enum is defined in a header file but nowhere else used,
1287 (by typedefing, pointer referencing or declaration) the mipsread code
1288 builds the complete tree for the structure but leaves its code as
1289 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1290 Guess its type based on the details of the members.
1292 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
1294 * infrun.c (wait_for_inferior): Check return value from
1297 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
1299 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
1300 by my last edit to this routine.
1302 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
1304 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1305 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1306 the values before putting them into the dummy code. (From Peter
1309 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
1311 * configure.in: added ebmon target.
1313 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
1317 * Makefile.in: Roll VERSION to 4.2.
1318 * README, TODO, WHATS.NEW: Update.
1320 * core.c (core_open): Improve error message for bad file.
1321 Pass .reg virtual memory address to fetch_core_registers to help
1322 it find the registers in the core-file header.
1323 * coredep.c (fetch_core_registers): Take new argument, use it,
1324 and pass it to register_addr to locate the block of registers.
1325 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
1327 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
1328 Sequent N_FN_SEQ like everybody else's N_FN.
1330 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
1331 * tm-i386v.h: #endif guck.
1332 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
1333 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
1334 * xconfig/tahoe: Add REGEX, which seems to be missing.
1336 * coredep.c: Add <sys/types.h> for SCOnix.
1337 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
1338 * printcmd.c (print_formatted): Flush output before disassembly.
1340 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1342 * doc/refcard.tex (sec "Working Files"): consistent metavars and
1343 other improvements, due to comments by François Pinard
1344 (pinard@iro.umontreal.ca)
1346 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
1347 configure, and improvenets related to Pinard's refcard comments
1349 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
1351 Changes from Fred Fish:
1352 * tm-68k.h (FPI_REGNUM): Add.
1353 * infrun.c (child_create_inferior): flush stdout and stderr
1355 * configure.in: Handle amigados, amix hosts and targets.
1356 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
1358 From Andreas Schwab:
1359 * values.c (show_convenience): Use printf_filtered.
1360 * main.c (define_command): Check result of lookup_command for
1362 (echo_command): Use printf_filtered, and force output out.
1364 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
1366 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
1367 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
1368 * configure.in, tconfig/decstation, xconfig/decstation: Rename
1369 dec3100 to decstation.
1371 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
1373 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
1374 (nodes Continuing and Stepping; Memory; Targets) clarifications
1377 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
1379 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
1380 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
1382 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
1384 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
1385 generic routines for calling inferior functions.
1387 * blockframe.c (inside_main_scope, inside_entry_scope): New.
1389 * copying.awk: Filter formfeeds out of copying & warrantee.
1390 Make them available as `show copying' and `show warrantee' also.
1391 * main.c (print_gnu_advertisement): Advt `show' commands.
1393 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1395 * mach386-xdep.c: Even when cross-compiling, leave in the
1396 core-file reading code.
1397 * core.c (get_core_registers): Avoid coredump if no .reg section.
1399 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1401 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1402 This avoids coredumps under `set print object on' in value_headof
1403 (called erroneously by value_from_vtable_info) for `p &struct'
1404 or `p *struct'. From Peter Schauer.
1406 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1408 * Makefile.in: Roll version to 4.1.2.
1409 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1410 size from BFD (but, FIXME, we don't yet read external nlists's and
1411 convert them to internal nlists's before handling them -- we still
1412 assume they have the same size and alignment.) Use SET_NAMESTRING
1414 * exec.c (exec_file_command): Move dead coff-encapsulation code
1416 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1418 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1420 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1421 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
1423 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1425 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1426 * mips-xdep.c (store_inferior_registers): Don't try to
1427 write the (pseudo) FP.
1428 * mipsread.c (parse_partial_symbols): Improved algorithm for
1429 setting pst->texthigh.
1431 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1433 * doc/Makefile: make TEXINPUTS include . everywhere
1435 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1437 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1438 vestiges of typevectors, which were for symsegs and are no longer
1439 used. (From a question by Eliot Dresselhaus
1440 <dresselh@RFT30.nas.nasa.gov>).
1442 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1444 * dbxread.c, coffread.c: static-ize functions that were
1445 gratuitiously external. (From Fred Fish.)
1447 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1449 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1450 until it is large enough.
1452 * dbxread.c (read_type): Handle error case slightly better.
1453 Make complaint message not C++-specific.
1455 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1457 * infrun.c (wait_for_inferior): Fix step/next so that you only
1458 stop at the beginning of a new line. This fixes various problems
1459 with for loops, nested if-else's and switch statements.
1461 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1463 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1464 between symtabs and psymtabs become ordinary error()s.
1466 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1467 properly, making "end pc" correct in shared lib psymtabs.
1468 (From Guy Harris <guy@auspex.com>.)
1470 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1472 * dbxread.c: Enable, but soften, const_vol_complaint.
1473 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1474 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1475 should be file-scope, not global.
1476 (read_struct_type): Remove ancient multiple-inheritance warning.
1477 (read_range_type): Check base type, complain & patch if undefined.
1478 * stack.c (frame_info): Demangle the function name in `info stack'.
1479 (From Peter Schauer)
1481 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1483 * eval.c (evaluate_subexp_for_address): Don't use
1484 TYPE_POINTER_TYPE directly (it might be zero if this type has
1485 never had a pointer created before); use lookup_pointer_type.
1486 * symtab.c (lookup_method_type): Arguments were swapped in all
1487 callers, so fix it here. I'm amazed this worked at all!
1489 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1491 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1492 "bss" rather than "data" symbols, but which still conflict.
1495 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1496 * core.c (core_files_info): Shorten output.
1497 * exec.c (exec_files_info): Ditto.
1498 (build_section_table): Ignore zero-length sections.
1499 * language.c, printcmd.c: Lint.
1500 * language.h (get_frame_language): Declare.
1501 * saber.suppress: update.
1502 * stack.c (find_relative_frame): Remove complex code that was
1503 #if 0'd, stick with simple code. Lint.
1504 * saber.suppress: Update a bit.
1505 * symfile.c (add_symbol_file_command): Add "?" to question.
1506 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1507 * value.h: Declare typedef_print.
1509 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1512 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1513 (Reported by Mark Peek <mark@imagen.com>.)
1515 * solib.c (solib_map_sections): Relocate all sections, even
1516 though only the text section's size is tracked. Mark ld_text
1517 for eventual elimination as we generalize to N sections.
1519 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1520 call_dummy if we were stopped by a random signal that is being
1521 passed to the program. This produced wierd results when calling
1522 functions in the inferior and signals (e.g. SIGALRM) were in use.
1524 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1526 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1527 Bugfix from Paul Eggert <eggert@twinsun.com>.
1528 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1529 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1532 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)

1538 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1542 * Makefile.in (VERSION): Set to 4.1.
1543 * language.c (set_language_command): Print useful help message,
1544 and restore the language string after giving help.
1545 * valprint.c (typedef_print): Print typedef in C or M2.
1546 * symtab.c (list_symbols): Use it.
1547 * main.c (main): Avoid any output before (gdb) prompt when -q.
1548 * language.c (set_language_command): Handle errors by restoring
1549 the language string to its current state (fix from A. Beers).
1550 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1551 "how to install" and "how to print the doc" stuff so it drops
1553 * configure.in: Rename rtpc CPU to romp to match config.sub.
1554 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1556 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1558 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1559 autoloading shared libs, copyright etc on GDB startup, clean up $_
1560 and $__ index refs, set/show listsize and related updates to list
1561 cmd. New host/target configs.
1563 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1565 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1566 from main Makefile.in version definition
1567 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1569 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1571 * doc/gdb.texinfo: merge new language-switching and lang-specific
1574 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1576 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1577 compilers (which may lack stddef.h).
1579 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1581 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1582 N_WARNING are the same except for the N_EXT bit, so just use their
1583 values alone, rather than OR-ing them with N_EXT.
1585 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1587 * mipsread.c (parse_lines): Deal with negative extended line
1590 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1591 global symbol conflicts.
1593 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1595 * .gdbinit: Move 'set complaints' to top, so it runs even in
1596 case we aren't debugging GDB.
1597 * language.c (_initialize_language): Fix type check and range
1598 check documentation strings.
1599 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1600 language.c can use it. (Though language.c should really not be
1601 handling warnings/errors the way it does, FIXME.)
1602 * symtab.c (lookup_primitive_type): const lint.
1604 Bugfix from Peter Schauer:
1605 * source.c (lines_to_list): Make signed, to avoid comparison
1606 going unsigned and complaining that -3 is too high for 21 lines.
1607 * stack.c (lines_to_list): Ditto.
1609 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1611 * Makefile.in (HFILES): Add minimon.h.
1612 (VERSION): Roll version number to 4.0.95.
1613 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1614 New rules for building distributions. Normal distribution
1615 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1616 one level up from here; it calls make-proto-gdb.dir to build a
1617 directory `proto-gdb' which is an image of the release. The old
1618 `gdb.tar.Z' rule still works too.
1619 * config.sub, configure: Roll in latest from ..
1621 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1623 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1624 new-target, and new-config chapters; fix minor typos; come closer
1625 to usual GNU markup conventions for @file @samp @code @var.
1627 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1629 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1630 * mipsread.c (parse_partial_symbols): Enter the name of all
1631 structs/unions... into the psymtab so we can access them if the
1632 symtab is not read in.
1633 * mips-tdep.c: Remove some unneeded #includes.
1634 * xconfig/dec3100: Add HAVE_STRSTR.
1636 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1638 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1639 * c-exp.y, m2-exp.y: Lint.
1640 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1641 * valprint.c (val_print_fields): Check for stub type.
1642 * mipsread.c (_initialize_mipsread): Avoid using
1643 builtin_type_void at initialize time.
1644 (mipscoff_symfile_read): use it now.
1646 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1648 Merge multiple-language support, and partial Modula-2 support,
1649 from Andrew Beers <beers@cs.buffalo.edu>.
1651 * i387-tdep.c: New file, consolidates most 80387 support,
1652 and eliminates host dependency on double<->extended conversions.
1653 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

1671 (process_coff_symbol): #if 0'd for functions and params as above.
1672 (read_enum_type): Recognize Modula-2 BOOLEAN.
1673 * symtab.c (add_param_to_type): #if 0'd function to add a

1678 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1679 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1680 hex with local_hex_string for Modula-2 support.
1682 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test

1685 * parse.c: New file with the common code remains of expread.y.
1686 * parser-defs.h: New file with common declarations from expread.y.

1709 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1711 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1712 * expprint.c: Look up expression opcodes in language-specific

1745 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1747 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1748 entries are enclosed herein. Not all of these changes
1749 have been merged into the master GDB sources -- check the
1750 ChangeLog above here for the merge log.
1752 Mon Jun 3 17:05:45 EDT 1991
1754 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1755 operators were added, C specific operators and tokens
1756 removed. yylex() revamped to some extent. Still things
1757 missing from the grammar, such as sets.
1758 Tested for two weeks in GDB v3.5.
1760 Tue Jun 11 17:23:48 EDT 1991
1762 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1763 so they are built-in. Sort of a hack.
1765 Fri Jun 14 12:53:51 EDT 1991
1767 m2-exp.y Added range checking for numeric constants. Any numeric
1768 constant is assumed to be of builtin type INTEGER unless:
1769 (1) it is octal or hexadecimal, in which case it is a
1770 CARDINAL; (2) it is too big to fit into an INTEGER, in
1771 which case it is a CARDINAL.
1772 eval.c Added simple range checking for +, -, and * on integers.
1773 Doesn't work very well for *, since 6 * 1,000,000,000 =
1774 1,705,032,704, which fails the simple test of result >=
1775 first_operand, no matter in what order the operands are.
1777 Tue Jun 18 14:11:30 EDT 1991
1779 Broke the parser into parts, one containing the C grammar and the other
1780 containing code to be shared by all of the grammars.
1782 The following files no longer exist:
1787 The following files were added:
1789 c-exp.y (The C grammar)
1790 m2-exp.y (The Modula-2 grammar)
1791 parser-code.c (Code that is shared by the above grammar)
1795 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1796 now necessary to use the Bison compiler compiler, since it
1797 will generate function/variable prefixes other than yy.
1799 Tue Jun 18 16:47:49 EDT 1991
1801 symtab.[ch] Added the external variable working_lang, than holds the
1802 value of the current working language.
1803 Added the ennumerated type language_mode, with the values
1804 language_auto and language_manual, the former meaning that
1805 GDB sets working_lang as needed, and the latter meaning
1806 that the value of working_lang is totally under user
1808 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1809 REAL, BOOLEAN and CHAR. Also added the type codes
1810 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1811 utils.c Added set_language_command and show_language_command to
1812 implement the GDB support commands "set language" and
1814 expression.h A number of identifiers were added to the type exp_opcode
1815 to facilitate Modula-2 builtin functions, integer
1816 division, and array indexing.
1818 Wed Jun 19 13:25:58 EDT 1991
1820 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1821 if the language specified by working_lang requires the use
1822 of strict typing of expressions. Eventually, even this
1823 will be able to be changed by the user.
1824 Added the macro RANGE_CHECK, which evaluates to non-zero
1825 if the language specified by working_lang requires the
1826 checking of a value against the domain of its type.
1827 Eventually, even this will be able to be changed by the
1829 language.[ch] Predicates involving types (simple_type, ordered_type,
1830 same_type, integral_type, numeric_type, character_type,
1831 boolean_type, float_type) are added. These predicates are
1832 based on the current value of working_lang, and are handy
1835 Wed Jun 19 15:39:34 EDT 1991
1837 eval.c Added the function type_array_rank which computes the rank
1839 valarith.c Added the funtion value_bool, which when given a integer
1840 value.h value (ie. struct value *) as an argument, it returns a
1841 boolean value (ie. struct value *) true if that integer
1842 is non-zero, and a boolean value false otherwise.
1843 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1844 will print out properly.
1846 Wed Jun 19 16:36:34 EDT 1991
1848 valops.c Added the function value_capitalize, which returns it
1849 value.h argument capitalized if its argument is a lowercase
1850 letter, or the argument unchanged if its argument is not a
1852 valarith.c Added the function range_check_p, which returns non-zero
1853 value.h if its value argument is between the integral bounds upper
1855 Added the function range_check_enum_p, which makes sure
1856 that its value argument is a valid member of the domain of
1858 Added the function range_check_range_p, which makes sure
1859 its value argument lies between the upper and lower bounds
1860 of its type argument, which must be a ranged type.
1861 Added the function check_array_index, which range and type
1862 checks an index of an array.
1863 Added the function value_multi_subscript, which computes
1864 array[idx1,idx2...idxN], given a value array and an array
1865 of values representing indicies.
1866 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1867 unpack_long to work with TYPE_CODE_BOOL and
1870 Wed Jun 19 18:04:08 EDT 1991
1872 symtab.c Stored pervasive types in a structure and make
1873 lookup_pervasive_type() a lookup function that was based
1874 on working_lang. If lookup_pervasive_type() returned
1875 non-zero, then that value was returned (a fix, since
1876 before it simply wouldn't return the pervasive type.)
1877 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1878 non-zero if the language specified by working_lang means
1879 "conversion" when it says "cast".
1880 valops.c Added the function value_real_cast(), which performs a
1881 value.h *cast*, not a *conversion*, which is what value_cast()
1882 does when it can. In particular,
1883 value_cast(<float_type>,4) = 4.0, while
1884 value_real_cast(<float_type>,4) = some mess.
1885 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1886 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1887 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1888 and MIN on integral types. *NOTE*: These are currently
1889 hardcoded to work only if there are 8 bits per storage
1891 eval.c Made logical functions call value_bool to return a
1892 properly typed boolean value, based on working_lang.
1894 Thu Jun 20 11:55:27 EDT 1991
1896 valprint.c Types now print out in a Modula-2 fashion. This works for
1897 the cases when the type is printed out step-by-step, that
1898 is, it doesn't work when the name of a structured type
1899 (which includes the keyword "struct", etc.) is simply
1901 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1902 since type specifications in C and Modula-2 are very
1903 different. The C printing of a type is very recursive,
1904 whereas in Modula-2 it is generally very simple. C has
1905 type prefixes and suffixes, which have no real analogue in
1906 Modula-2. Maybe type_print() should call a language
1907 specific type printer. This is also advantageous if we
1908 compile GDB to exclude some of the languages. We'll just
1909 leave those functions out.
1911 Thu Jun 20 16:57:10 EDT 1991
1913 dbxread.c When reading the complete symbol table in (via
1914 psymtab_to_symtab()), the number and types of function
1915 arguments are added to a function type. define_symbol()
1916 calls add_param_to_type() to accomplish this.
1917 Assumption: when we come across a function definition
1918 (N_FUN symbol with an 'f' or 'F' in the name), its
1919 arguments will appear before another function definition.
1920 When a function is found, a pointer to its type is placed
1921 in the global in_function_type. Changes that
1922 add_param_to_type() makes are to this global.
1923 valprint.c The type of a function now includes (for Modula-2) the
1924 types of its parameters.
1925 eval.c Type checking and a check for the proper number of
1926 arguments is now done for function calls. Not sure of the
1927 impact this has on C++ member function yet.
1929 Thu Jun 20 19:58:48 EDT 1991
1931 valprint.c Rewrote the type printer. Broke it into two language
1932 specific parts, adding the functions type_print_m2() and
1934 An unfortunate consequence is this: if you debugging a C
1935 program in Modula-2 mode (why?), info types does not work
1936 well with regular expressions, since the types are printed
1937 out in Modula-2 terminology, but stored in C terminology.
1938 language.[ch] Added the functions new_type_last(), type_keyword(), and
1939 type_sep() to aid in the printing of typedefs.
1940 symtab.c Made the printing of typedefs as language independent as
1941 possible through calls to new_type_last(), type_keyword(),
1944 Fri Jun 21 11:50:26 EDT 1991
1946 dbxread.c Check all incoming ennumerated types. If it looks like
1947 Modula-2's BOOLEAN type, then change the type_code of the
1948 type to TYPE_CODE_BOOL so we can process it as a boolean
1950 valprint.c Replaced some of the 0x%x with calls to sprintf and
1951 hexformat() in val_print().
1952 language.[ch] Added the function hex_to_string(), which converts its
1953 integral argument to a hexadecimal number (format is
1954 language based) and returns the result as a string.
1956 Mon Jun 24 12:25:07 EDT 1991
1958 valprint.c Some functions call type_print_1() directly, instead of
1959 value.h using type_print(), so they can specify where (column) to
1960 print things. Since type_print() takes care of language
1961 dependence, that needs to be called first. Added a
1962 parameter depth to type_print() (so it is now like
1963 type_print_1). Changed type_print to type_print_at, and
1964 made type_print a macro that passes a depth argument of
1966 symmisc.c Changed all calls to type_print_1 to calls to
1968 Makefile.dist Made it possible to build GDB for a specific set of
1969 depend languages. Do this by passing a definition for the macro
1970 LANGS to make. LANGS should be a string containing a
1971 space-separated list of language names (ie. LANGS="c m2").
1972 The default is to build all languages. Note that grammar
1973 files must follow the naming convention of <lang>-exp.y.
1974 gdb.lang This holds the current value of the LANGS macro. It is
1975 examined every time make is called, and is updated if
1977 eval.c Added #ifdef _LANG_<lang> to these files.
1978 expread.c Still need to add them to dbxread.c and coffread.c.
1986 Mon Jun 24 16:33:11 EDT 1991
1988 language.[ch] Added the functions hexformat_pre() and
1989 hex_to_string_pre(), which take a prefix argument to
1990 include in the format string. Thus, hexformat_pre("08") will
1991 return "0x08x" (if the working language is language_c).
1992 Made hexformat() and hex_to_string() calls to the above
1993 with "" as the prefix argument.
1995 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1996 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1997 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1998 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1999 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
2000 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
2001 valprint.c, vax-pinsn.c
2003 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
2004 calls to hexformat() and hex_to_string(). Format strings without
2005 the leading "0x" were ignored.
2007 depend Updated to take the above into account.
2010 Tue Jun 25 15:27:18 EDT 1991
2012 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
2013 and type_check_t to keep track of the current state of
2014 range and type checking.
2015 main.c Added the variables range_mode, range_check, type_mode,
2016 and type_check to record the current state of range and
2017 type checking. Added initialization code to main().
2018 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
2019 the above variables.
2022 Tue Jun 25 17:57:08 EDT 1991
2024 dbxread.c process_one_symbol() updates the variable (enum language)
2025 source_lang based on the extension of the filename
2026 contained in the N_SO sybmol that started this symtab.
2027 When end_symtab() is called, the value of source_lang is
2028 put into the language field.
2029 stack.c select_frame() sets working_lang (and possibly type_check
2030 and range_check) to the language field of the symtab
2031 associated with the frame that is selected if working_mode
2032 is language_auto. If working_mode is language_manual, a
2033 warning is printed and working_lang is not set.
2034 language.c Added the function set_type_range(), which sets the value of
2035 type_check and range_check (if their modes call for
2036 automatic setting) based on the current value of
2037 working_lang. A non-zero argument will cause the current
2038 settings to be output.
2041 Wed Jun 26 14:51:40 EDT 1991
2043 eval.c Added range checks on assignment.
2044 m2-exp.y Added the grammar for sets to the language. Currently,
2045 these do not do anything except print an error message.
2047 Wed Jun 26 17:01:04 EDT 1991
2049 m2-exp.y Added the ability for parse_number() to parse negative
2050 numbers. A global flag is set upon encountering a unary
2051 minus. This was done to make, for example, 1 parse as a
2052 CARDINAL, and not as an integer, per Wirth's examples in
2053 Programming in Modula-2 ed.4.
2054 valprint.c Added support for "set radix 2" by then setting
2055 output_format to 't'.
2056 eval.c Implemented range checking on subrange types. Added calls
2057 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
2058 Implemented MIN and MAX for ennumerated types. The
2059 minimum value of an ennumerated type is defined by Wirth
2060 as the first identifier, and the maximum as the last.
2061 m2-exp.y Made octal numbers ending with "B" be characters and those
2062 ending with "C" be numbers, per Wirth's book. (p. 34)
2064 Thu Jun 27 14:11:52 EDT 1991
2066 stack.c select_frame() now only sets working_lang, it does not
2067 notify the user. If working_mode is language_manual, then
2068 a warning is issued once.
2069 main.c At the end of each call to execute_command(), working_lang
2070 is checked against the local static (enum language)
2071 current. If they differ and working_mode is
2072 language_auto, the new settings of language, type and
2073 range checking are printed out.
2074 stack.c Modified frame_info() to include the language of the
2075 current frame in the output of "info frame".
2076 language.[ch] Added the function language_str() which returns the name
2077 of the current language.
2079 Fri Jun 28 15:33:14 EDT 1991
2081 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
2082 the language. INCL and DECL currently cause an error,
2083 since sets are not implemented yet. INC and DEC are
2084 implemented as PREINCREMENT/PREDECREMENT with one
2085 argument, and as ASSIGN_MODIFY with two arguments.
2086 eval.c Added type checking to the above cases.
2087 value.h Added not_lval_constant to the lval_type ennumerated type.
2088 not_lval_constant means that the value is a constant
2089 value; that is 3 or 'a' or TRUE, not as in a constant
2090 identifier. This is used to help coerce numbers such as 3
2091 to either signed or unsigned numbers.
2092 valops.c Added the function value_coerce_constants() which coerces
2093 constant integers as following: if one is a constant and
2094 the other is not, the constant's type is set to the type
2095 of the other argument. If both are constants and one is
2096 signed, the other is converted to a signed constant.
2098 Sat Jun 29 17:26:29 EDT 1991
2100 valarith.c Added a better range checker. It now checks range
2101 (successfully) on integral operations [+-] (signed and
2102 unsigned) for any C sized type. Still does not work well
2103 for multiplication.)
2104 int_in_size() returns an integer that is coerced to fit into
2105 specified number of bytes.
2107 Mon Jul 1 13:04:14 EDT 1991
2109 language.[ch] Added the function binop_result_type(), which returns the
2110 builtin (struct type *) type that would be the result of a
2111 binop on the two values V1 and V2.
2113 Wed Jul 3 19:22:53 EDT 1991
2115 source.c Extended source_info() to include the source language in
2116 the output from "info source".
2118 Fri Jul 5 13:48:52 EDT 1991
2120 utils.c Moved the support functions for the GDB set/show commands
2121 dealing with language into language.c.
2122 language.c Added the function language_info(), which displays info
2123 about the current working language, type and range check
2124 settings. Called via the GDB command "info language".
2125 Added an initialization routine _initialize_language(),
2126 that sets defaults for the language, type and range
2127 variables and sets up the new GDB commands.
2128 main.c Language setup moved to language.c.
2131 Mon Jul 8 10:10:22 EDT 1991
2133 valarith.c Debugged the range checker for arithmetic. Still does not
2134 work for multiplication very well.
2136 Mon Jul 8 12:40:37 EDT 1991
2138 language.[ch] Added the function value_true() which returns non-zero if
2139 its argument represents a boolean true value.
2140 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
2141 check the truth of an expression.
2143 Thu Jul 11 12:51:34 EDT 1991
2145 language.[ch] Added the predicate structured_type(), which returns
2146 non-zero if the argument is a structured type.
2147 Added the predicate pointer_type(), which returns non-zero
2148 if the argument is a pointer type.
2149 eval.c Added the ability to do addition and substraction on
2150 pointers and integers. This case simply bypasses the
2153 Thu Jul 11 14:41:42 EDT 1991
2156 Added the symbol N_DEFD (0x4a) which is a definition
2157 module dependency that is used by the GNU Modula-2
2158 compiler and the linker. It is not important to GDB,
2159 except that [dbx|coff|mips]read.c should ignore these
2162 Fri Jul 12 16:07:00 EDT 1991
2164 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
2165 0 in val_print(). Also added statements to the else part
2166 to coerce type (argument to val_print) to a pointer type
2167 if it is an "array of unspecified length".
2168 valops.c Added the function value_m2_string(), which returns a
2169 (value) value which is a constant string, whose type is
2170 (ARRAY [0..n] OF CHAR). The length field of the type
2171 structure is set to zero, so it will be interpreted as an
2172 "array of unspecified length".
2173 stack.c Moved the language/frame mismatch check to
2174 main.c:execute_command().
2175 main.c The working language is recorded each time
2176 execute_command() is executed. If working lang has
2177 changed during its execution, then the new
2178 language/type/range info is printed out for the user. If
2179 the working language does not match the language of the
2180 frame, a warning is issued.
2182 Sat Jul 13 16:16:39 EDT 1991
2184 eval.c Moved all the type-checking stuff for operators to
2185 language.[ch] language.c. This is so we can keep language-specific
2186 stuff (like for what type operators are defined) in
2188 language.[ch] Added the function binop_type_check(), which checks to see
2189 if its two (value) arguments are type-compatible with its
2190 opcode argument. The opcode should represent an operation
2191 involving an operator. Also added the macro function
2192 unop_type_check, which calls binop_type_check with a
2193 NULL second argument.
2194 expprint.c Added Modula-2 operators to the op_print_tab, so info
2195 expression.h break works correctly. Also added "op_string", which
2196 returns the string corresponding to the (enum exp_opcode)
2197 opcode that is its argument.
2200 Sat Jul 13 18:26:18 EDT 1991
2202 coffread.c Added code to record the type of function arguments with
2203 each paricular function. Code is very similar to that
2205 dbxread.c Moved add_param_to_type() to symtab.c
2206 symtab.[ch] Added function add_param_to_type() from dbxread.c
2208 *** NOTE: The above additions have not been tested.
2210 Mon Jul 15 12:50:47 EDT 1991
2212 langauge.[ch] Added the functions type_error and range_error, which work
2213 like error() except if the type/range mode is set to
2214 *_mode_warn, then they do not do a return_to_top_level(),
2215 but merely print a warning.
2216 Also changed [set|show]_[type|range]_command() to support
2217 the new "warn" feature.
2219 Thu Jul 18 17:50:54 EDT 1991
2221 mipsread.c Added code to record the type of function arguments with
2222 each particular function. Code is very similar to that
2225 *** NOTE: The above additions have not been tested.
2227 Fri Jul 19 11:19:10 EDT 1991
2229 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2230 UMIN_OF_SIZE, which when given a size of a numeric type,
2231 return the maximum and minimum value it can hold. UMAX...
2232 and UMIN... return the result for unsigned types.
2233 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2234 struct types. They call above macros.
2235 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2236 avoid a name conlict with the above.
2237 c-exp.y Added range checking on numeric constants in
2238 parse_number() for completeness.
2239 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
2240 return 0 if working_lang is not language_c.
2242 Thu Aug 8 14:17:22 EDT 1991
2246 breakpoint.c Documentation strings of some commands changed to
2247 eliminate the references to the C language where
2250 Tue Aug 13 15:48:03 EDT 1991
2252 m2-exp.y Added qualified identifiers to the grammar. The semantics
2253 are slightly different from those of the GDB operator ::
2255 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
2256 type_exp, where type_exp is any valid type expression.
2258 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
2259 printcmd.c Modified ptype_command() so it actually parses the input
2260 (necessary for type expressions with scope qualifiers).
2261 Added the function ptype_eval() which expects an
2262 expression composed of one OP_TYPE element.
2263 *.[ch] Replaced all occurences of parse_c_expression with
2265 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
2267 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
2269 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
2271 Small fixes from Peter Schauer:
2273 * infrun.c (child_attach): Lint.
2274 * solib.c (find_solib): Handle shared libs version 2.
2276 Small fixes from David Wood:
2278 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
2282 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
2283 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2285 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
2286 chars_per_line is at maximum (user typed `set width 0'). Fix
2287 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2289 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
2291 * coredep.c: include ptrace.h where necessary.
2292 * mipsread.c(parse_lines): fix unsigned char problem that was
2293 messing up line numbers on SGI's and possibly other MIPS based
2295 * infrun.c (child_create_inferior): use better test to check
2296 return val from setpgrp().
2297 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
2298 for sgi/irix support.
2300 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
2302 * mipsread.c (parse_symbol): Put non-static procedures
2303 in the global block.
2305 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2307 Patch together `text_start' and `text_end' for 29K port.
2309 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2310 variables and set them based on the exec file.
2311 * am29k-tdep.c: declare text_start.
2312 * valops.c (call_function_by_hand): declare text_end.
2314 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2315 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2316 because machines that do this will also have to know to
2317 set NEED_TEXT_START_END. Besides, it was a redundant way to
2319 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2320 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2321 NEED_TEXT_START_END.
2323 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2325 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2327 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2328 Pass MUNCH_DEFINE to munch whenever we run it.
2329 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2330 format string; use 0x%x instead.
2331 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2332 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
2333 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
2334 * inflow.c: Handle `short' process group IDs.
2335 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
2336 and check for ptrace errors.
2337 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
2338 (coff_symfile_init): Initialize text_bfd_scnum.
2339 (read_coff_symtab): Use it to find the text [and absolute?] sections.
2340 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
2341 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2342 Merge target arm case with other "easy" cases. Add target
2343 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2344 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2346 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2347 * munch: Cope with RT/PC putting fns in data segment.
2348 Restore ability to override `nm' by specifying MUNCH_NM.
2349 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2350 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2351 and remote-adapt. Remove encapsulated coff #define's (the
2352 support should go in BFD, and gdb shouldn't know or care).
2353 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2354 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2355 * tm-29k.h: Update BADMAG (though it should go away).
2356 Allow the register definitions to be overridden in another
2357 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2358 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2359 DUMMY_SAVE_GR96, for handling kernel calling conventions
2360 that use GR64+ rather than GR96+.
2361 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2362 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2363 overrides various things.
2365 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2366 child_attach does, making a clean stop in the newly attached
2368 * remote-eb.c: Lint.
2370 * coffread.c: Make coffread independent of any particular
2371 variant of COFF. Avoid #include-ing any particular one except
2372 internalcoff.h. BFD now passes key values for symbol reading
2373 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2374 and the symbol masks and shifts); use them.
2375 Remove obsolete end_of_text_addr.
2377 * exec.c: Remove unused include files.
2379 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2381 * Makefile.in (documentation targets): Pass $(M4).
2382 Bugfix from eggert@twinsun.com (Paul Eggert).
2384 * stack.c (down_silently_command): Check for stack existence.
2386 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2388 * Makefile.in (VERSION): Update to 4.0.3.
2390 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2392 * core.c (core_file_command): Print frame at coredump with
2393 its level number, by calling print_stack_frame.
2394 * frame.h: Add selected_frame_level, print_stack_frame.
2395 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2396 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2397 Change print_sel_frame and print_selected_frame callers to
2400 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2401 * symfile.c (free_named_symtabs): Ditto.
2402 * main.c (main): wrap_here needs an arg.
2403 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2404 (solib_add): Avoid noise.
2405 (solib_create_inferior_hook): Lint.
2406 (sharedlibrary_command): Move dont_repeat to here.
2407 * utils.c (error): Call wrap_here to force buffered output.
2409 Small patches from Peter Schauer:
2411 * coffread.c (start_symtab): Free any existing line_vector before
2413 (read_coff_symtab): Ditto for type_vector.
2415 * source.c (lines_to_list): New variable, replacing function.
2416 (all uses): Use as variable.
2417 (_initialize_source): Add 'set listsize' and 'show listsize'.
2418 * utils.c (lines_to_list): Remove function.
2419 * stack.c (print_frame_info): Use as variable.
2420 * defs.h (lines_to_list): Remove declaration.
2422 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2424 * breakpoint.c (insert_breakpoints): Restore warning about
2425 the program might be running in another process, but only for
2426 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2427 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2429 * utils.c (error): if error_pre_print is set, print the string
2431 * main.c (main, print_gnu_advertisement, print_gdb_version):
2432 Reformat legalese so it always prints, but acts as an "I'm here"
2433 message while symbols are being read. If any errors occur,
2434 print a few newlines to set off the message and start it at the
2435 left margin. Remove mention of "help" command, and don't yak
2436 about symbol reading.
2437 (catch_errors): Error string is now printed first in case of
2439 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2440 suggest the "help" command.
2442 * Makefile.in (VERSION): Set to 4.0.2.
2444 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2446 * .gdbinit: Remove useless "rr" command. Set complaints
2447 to 1 for people debugging gdb.
2449 * breakpoint.c, remote-vx.c: Reword strings printed by
2450 catch_errors callers.
2452 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2454 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2455 (Fix from kenc@viewlogic.com.)
2457 Fix some infrastructure to be able to cope with host and target
2458 machines with different sized basic types (ints, ptrs, etc).
2459 (Idea from pierre@la.tce.com (Pierre Willard).)
2461 * values.c (value_from_longest): Rename from value_from_long.
2462 Handle pointer types as well as integers, so that targets with
2463 different pointer sizes from the host can be accomodated.
2464 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2465 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2466 uses of value_from_long to value_from_longest.
2467 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2468 the correct pointer type to value_from_long{est}.
2470 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2472 * remote-vx.c: Remove obsolete code for calling functions via
2473 vxworks kludge interface (it referenced value_from_long).
2475 * valops.c (value_string): Find malloc with lookup_misc_func, not
2478 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2480 Make writing to files work properly. (Fixes to BFD are also needed.)
2482 * core.c (core_open): Open file ourselves, read or r/w, depending on
2483 write_files. Use bfd_fdopenr.
2484 * gdbcore.h (write_files): New variable.
2485 * exec.c (write_files): Define variable, add set&show for it.
2486 (exec_file_command): Use write_files to open for read or r/write.
2488 Make shared library reading happen automatically. These changes
2489 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2491 * inferior.h (stop_soon_quietly): Add to exported variables.
2492 * infrun.c (child_create_inferior): call solib hook, if defined.
2493 (child_attach): call solib hook, if defined.
2494 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2495 (find_solib): Use lookup_misc_func rather than hand-rolled.
2496 (symbol_add_stub): New stub for catch_errors.
2497 (solib_add): Avoid output if !from_tty. Catch errors rather
2498 than just calling symbol_file_add and bombing.
2499 (solib_create_inferior_hook): Interface with the target process
2500 to let it read and alloc shared libs, then figure out what it did.
2502 * core.c (validate_files): Fix typo, soften warning.
2503 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2505 * utils.c (fputs_demangled): Avoid duplicate printing if
2506 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2508 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2509 (Fix from pierre@la.tce.com (Pierre Willard).)
2511 * main.c (catch_errors): Change argument to a char * from an int,
2512 since a char * can point to a struct full of glop, but an int
2513 is not guaranteed to be able to hold a pointer.
2514 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2515 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2516 * core.c (core_open, solib_add_stub): Adapt.
2517 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2519 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2521 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2522 by adding .NOEXPORT target.
2524 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2528 * Makefile.in (VERSION): Roll to 4.0.
2529 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2531 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2533 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2536 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2539 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2541 * Makefile.in, doc/Makefile, doc/gdb.texinfo:
2542 reflect above name change
2544 * WHATS.NEW: correct pointer to refcard.
2546 * doc/gdb.texinfo: update New Features, Installing
2548 * doc/gdbint.texinfo: add short description of configure +template
2550 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2552 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2554 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2556 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2557 tar file, add dependencies for referenced doc files.
2559 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2561 * coffread.c, symfile.c, stack.c: saberized.
2563 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2565 * doc/refcard.tex: permuted Essential Commands sec
2567 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2569 set/show symbol-reloading
2570 default set complaints 0
2572 RET-repeat disabled after prompted long displays
2573 processID (attach) interpretation of 2nd GDB cmdline arg
2575 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2577 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2578 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2579 breakpoint.c, main.c: lint.
2581 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2583 Install new configuration scheme for GDB and friends.
2585 * config.sub: Translate ordinary names to three-part names.
2586 * configure: Use three-part names internally.
2587 * configure.in: Translate three-part names to filenames.
2589 * README, WHATS.NEW: Update for gdb-4.0.
2590 * Makefile.in: Roll VERSION to 3.99.
2592 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2594 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2595 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2596 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2597 to single structures rather than arrays; when passing
2598 their address, use &. This avoids trouble with bdead compilers.
2599 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2600 instead. This avoids portability headaches.
2601 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2603 * source.c (open_source_file): Avoid ANSI const bdeath by
2604 skipping declaration and then casting result value.
2605 * tm-hp300bsd.h: Clarify comment.
2606 * utils.c (strstr): Result is const char *; ANSI bdeath.
2607 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2608 since system include file defines it differently from "defs.h",
2609 though the two are equivalent for our purposes.
2610 * tconfig/hp300bsd: Add m68k-tdep.o.
2612 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2614 * tconfig/sun*4: Remove warnings about system assembler.
2616 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2618 * mcheck.c: Avoid warning about undeclared abort fn.
2619 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2620 it causes recursive calls to error() when used in cleanups.
2621 To do so requires that we make it a function, so we do.
2622 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2623 * utils.c (do_cleanups): Remove the current cleanup from the
2624 chain *before* calling it, in case error() is called from it.
2625 The result won't be pretty, but won't be an infinite loop either.
2627 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2629 * dbxread.c (read_struct_type): Grok anon structs for C++.
2630 (vb_name, vptr_name): Null terminate these strings.
2632 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2634 Minor bug fixes from BSD Net2 gdb:
2636 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2637 returns 0, there is no previous frame.
2638 * breakpoint.c (commands_command): If !from_tty, don't call
2639 input_from_terminal_p().
2640 * dbxread.c (record_misc_function): Speed up slightly.
2641 (compare_psymbols): Ditto.
2642 * infcmd.c (do_registers_info): Take a second argument to
2643 determine whether to print float registers. "info registers"
2644 does not do so anymore. "info all-registers" does, now.
2645 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2647 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2648 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2652 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2653 executing_breakpoint_commands if we are interrupted by error.
2654 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2655 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2656 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2657 catch_errors() so we can setup the frame regardless of whether
2658 the shared libs work.
2659 * ieee-float.c (double_to_ieee_extended): Get exponent from
2660 right place in little-endian systems. From John Carey.
2662 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2664 * main.c: Remove unused terminating_signals and catch_termination().
2665 (long_options): Terminate with a zero element.
2666 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2667 (gdb_readline): Make call-compatible with readline.
2668 (init_signals): Improve comments re vfork vs. signal.
2670 * utils.c (prompt_for_continue): Use new gdb_readline().
2671 If we prompt for continuation, we don't let CR repeat the previous
2672 command, once we get back to a prompt. It's too easy to keep
2673 hitting CR, expecting "--more--" prompts, and have some long
2674 command start repeating on you.
2676 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2678 * blockframe.c (frameless_look_for_prologue): Speed up by
2679 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2680 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2681 Define two variants, one faster.
2682 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2683 and return zero, rather than giving an error.
2684 (setup_arbitrary_frame): Initialize the PC in the new frame.
2685 (skip_prologue): Add a second arg saying whether we're just
2686 checking for a frameless function or not.
2688 * core.c (core_open, core_close, core_xfer_memory): Move
2689 section table pointers and bfd* into the target_ops.
2690 (core_open): Allow errors in shared lib reading, etc.
2691 (core_files_info): Describe shared library sections.
2693 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2694 exec_files_info, set_section_command): Move section table
2695 pointers and bfd* into the target_ops.
2696 (add_to_section_table): Add BFD to section table.
2698 * target.c (target_xfer_memory, target_info): Pass target to
2699 xfer_memory and target_info functions.
2702 * gdbcore.h: Move struct section_table.
2703 * target.h: New home of struct section_table.
2705 * solib.c (solib_add): New argument is the target_ops whose
2706 section list is to be added to, if any. Reallocate the
2707 sections in that target to add any that come from shared libs.
2708 (throughout) so_sections renamed to sections.
2709 (solib_xfer_memory): Deleted.
2710 * tm-sunos.h (SOLIB_ADD): Add target argument.
2711 (SOLIB_XFER_MEMORY): Delete.
2713 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2714 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2715 from target_ops. It's the same on all targets. Add two section
2716 pointers to target_ops.
2718 * stack.c (find_relative_frame): Dump ancient algorithm for
2719 "down", just use handy "next" pointers.
2720 (frame_command): Don't error if there is no stack; let user
2723 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2724 modifies static state in the parent process; new_tty itself
2725 runs in the child and modifies the child's file descriptors
2726 to match the saved static state.
2727 * infrun.c (child_create_inferior): Call new_tty_prefork,
2730 * infptrace.c (child_xfer_memory): Add ignored target arg.
2731 * remote-eb.c (eb_xfer_inferior_memory): ''
2732 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2733 * remote-vx.c (vx_xfer_memory): ''
2734 * remote.c (remote_xfer_memory): ''. Rename from
2735 remote_xfer_inferior_memory.
2737 * main.c (main): Only try to attach "corefile" argument if
2738 it starts with a digit.
2740 * symfile.c (symbol_reloading): New "set/show" variable.
2741 (symbol_file_add): Shorten message about symbol reading.
2742 (add_symbol_file_command): Merge with add_syms_addr_command,
2743 since this should work on all targets now.
2744 (stop_whining): Default to zero, to shut up complaints
2745 about bad symbol tables on many systems.
2746 (free_named_symtabs): Just exit unless symbol_reloading.
2748 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2749 and add comment explaining shared library screw.
2751 * source.c: #if defined => #ifdef.
2753 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2755 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2757 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2759 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2760 (doc/Makefile knows how to make one for local config)
2762 * Makefile.in: use doc/Makefile for doc targets
2764 * doc/Makefile: GDB documentation now has its own Makefile
2765 doc/refcard.tex: renamed from "gdbrc.tex"
2766 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2769 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2771 * values.c (baseclass_addr): When reading target memory, use the
2772 length of the basetype, not the upper type. We've only malloc'd
2773 enough space for the basetype, leading to errors in free().
2775 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2776 ends up as a function specially, since we know the actual type of
2777 the pointed-to address. This (somewhat) fixes display of
2778 expressions that include misc_function_vector names. Try `cond 1
2779 !strcmp("a","b")' then `i b'.
2781 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2782 The child can be proceeded from inside wait_for_inferior in
2783 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2784 getting skipped in that case.
2786 * expprint.c (print_subexp): Use filtered output, since the
2787 subroutines we call use it, otherwise the output is horribly
2788 mangled, since output of wrappable stuff comes out late.
2790 * Makefile.in: Bump VERSION to 3.98.1
2792 * infrun.c (child_create_process): Use execlp to find the
2793 shell to exec our target program. This requires some fiddling
2794 with `environ' since there is no execlpe().
2796 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2798 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2799 Minor rearrangement of refcard permits two new make targets--
2800 gdbrc.dvi DVI output for refcard, using CM fonts
2801 gdbrc.ps PostScript refcard, using PS fonts
2803 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2807 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2808 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2810 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2812 * doc/gdb.texinfo: last changes for release.
2813 Minor typo and formatting fixes; incorporated most fixes remaining from
2814 filed mail commenting on earlier drafts.
2816 Added warnings: pipes don't work in run command;
2817 conditions are converse of assertions;
2818 step over fn without debug info goes to next fn;
2819 vars may have "wrong" values near fn entrance, exit
2821 Added example from Kingston on printing repeated nonadjacent values
2823 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2824 shell mode for signals
2826 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2827 doesn't sound so much like its parent "Stopping and Continuing"; also
2828 moved entries on continue to top of section, so they don't get lost.
2830 Improved installation directions in appendix, added manual formatting
2833 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2835 * configure.in: Remove xm.h and tm.h even if we aren't linking
2836 new ones, so "./configure sun4; ./configure none" does the right
2837 thing. Assume that alldeps.mak and depend are already built in
2838 srcdir, and avoid running "make" (particularly "make depend",
2839 which involves "gcc") from inside configure. Build Makefile
2840 directly rather than building Makefile.conf first.
2841 * configure: Regenerate with above changes.
2842 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2843 to 3.98. Revise gdb.tar.Z procedure to produce a file
2844 called gdb-$(VERSION).tar.Z but which unpacks into a
2845 directory called "gdb". Move non-source files out of
2846 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2847 (depend): Don't try to do "gcc expread.y".
2848 (expread.o): Update dependencies by hand.
2850 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2853 Fixed a variety of small typos that prevented info from formatting
2854 cleanly; altered too-long heading for GPL Appendix, as discussed
2855 w/RMS; Changed date on cover to July 91.
2857 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2860 (1) Applied some fixes due to comments from Larry Breed (easier ones
2861 through chapsec 5.2)
2862 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2863 it's broken in latest texinfo
2864 (3) Introduced *some* use of [] for optional arguments, where
2865 explanation is not simpler by listing cmd w arg and cmd w/out arg
2866 separately. Still not using @deffn.
2867 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2868 couple of headings are too long. Need patches to texinfo or revision
2871 * Partial update to README (which still needs work for this
2872 release!): (1) use of configure corrected for new script,
2873 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2875 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2877 * symtab.c (lookup_symbol): Don't complain right off about
2878 no debug symbols; use the misc function vector first.
2879 (list_symbols): Use misc function vector to find symbols
2880 that don't have debug info, and print them.
2881 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2882 PC range doesn't match symtab PC range, as it does on the
2883 MIPS because our symtab reading isn't perfect.
2885 * dbxread.c (dbx_symfile_read): Make warning about
2886 "no debug symbols" slightly nicer.
2888 * source.c (select_source_symtab): If "main" symbol exists,
2889 but decode_line_spec can't find line info, don't just return
2890 a zero; try other source symtabs or give an error.
2892 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2893 their low addresses first, then rip through fixing high addrs.
2895 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2896 <runene@ifi.uio.no>.
2897 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2899 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2901 * Minor, mostly mechanical, cleanup of doc subdir for clean
2902 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2903 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2905 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2907 Mostly MIPS and general symbol-reading fixups.
2909 * doc/gdbint.texinfo: Add documentation on symbol-reading
2912 * mipsread.c: Remove kludges around #include "ecoff.h".
2913 Remove redefinitions of a_magic, etc, no longer used.
2914 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2915 Fix global overview comments to match symfile.c protocol.
2916 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2917 (mipscoff_symfile_read): Eliminate unused code. Avoid
2918 sorting all the symtabs, when all we have read here is psymtabs.
2919 The symtabs are sorted as they are created anyway. Tell
2920 condense_misc_bunches whether we're mainline.
2921 (psymtab_to_symtab_1): Pass filename when recursing, to make
2922 stack trace more informative.
2923 (parse_partial_symbols): Assume cur_hdr as argument.
2924 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2925 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2926 the TYPE_NAME of char *, since that's done in symfile.c.
2927 (free_numargs, parse_symbol, add_symbol, add_block,
2928 shrink_linetable): Declare these fns void.
2929 (upgrade_type): Convert tree of if's to switch. Clean up
2930 bogus "off == 0" handling with a complaint. Avoid setting
2931 field bitpos and bitsize of array with lower and upper bounds.
2932 Check specified bitsize of elements against their actual type's
2933 bitsize, and complain if different. Complain about unknown
2935 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2936 (psymtab_to_symtab_1): Print names of subsidiary files that
2937 are being read in. FIXME, we read far too many files. This code
2938 is not the problem, the problem is in parse_fdr where the psymtabs
2940 (cross_ref): Result should indicate that we used one aux entry
2941 normally, or two if we encountered a "next" entry. This used
2942 to leave the caller pointing at the wrong aux entry.
2943 (add_symbol): If overflowed cur_block, reallocate it larger,
2944 chase all pointers to it, and complain(), rather than clobber memory.
2945 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2946 (new_field): Only allocate one field initially, not two.
2947 Pull ++ out of macro argument. Simplify.
2948 (_initialize_mipsread): Avoid initialization of importd
2949 global_psymbols and static_psymbols.
2951 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2952 to properly set pst->symtab; avoid searching for it.
2953 (symfile_fns): Improve comments, add a FIXME.
2954 * dbxread.c: Update comments to reflect symfile protocol.
2955 (read_ofile_symtab, end_symtab): Return the symtab.
2956 (psymtab_to_symtab_1): Set pst->symtab.
2958 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2959 whether we're mainline.
2961 * symfile.h (sym_fns): Remove unused sym_discard member.
2962 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2964 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2965 the environment variable is not.
2966 * infcmd.c (finish_command): Use filtered printfs.
2967 * cplus-dem.c: Add struct tags to a few unnamed structs.
2968 * valops.c (value_coerce_array): Improve comments.
2969 * valprint.c (type_print_varspec_suffix): Print array size only
2970 if greater than zero.
2971 * m88k-tdep.c: Shift some lines left by one space, that had
2972 apparently been trashed at some point.
2973 * TODO: More things to do, a few got done.
2975 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2977 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2978 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2980 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2981 * expread.y, findvar.c, symmisc.c: Ditto.
2982 * printcmd.c (address_info): Update printed forms of LOC_
2983 symbols. Elim LOC_EXTERNAL.
2984 (print_frame_args): Keep track of param stack offsets before
2985 re-looking up to find the local register param is kept in.
2987 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2988 Further integration of mipsread into gdb. Eliminate unused
2989 routines, duplicate declarations. Handle static symbols in
2990 psymtabs as well as external symbols. When reading symtabs,
2991 insert symbols into the correct block (global, static, or a local
2993 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2995 (mipscoff_symfile_read): Don't call select_source_symtab.
2996 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2997 rather than SYMBOL_VALUE.
2998 (parse_external): Comment clobbering of top_stack.
2999 (parse_partial_symbols): Update comments. Allocate and parse
3000 static symbols as well as external symbols. FIXME, enum values
3001 are not handled in this pass, but should be. Inline new_psymbol.
3002 Use SYMBOL_VALUE_ADDRESS.
3003 (psymtab_to_symtab_1): Read symbols into global static block
3004 by default (until enter some function's local block context).
3005 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
3006 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
3008 * source.c (select_source_symtab): Select a source symtab
3009 from either the symtabs or, failing that, the psymtabs.
3010 (list_command): Update error message.
3011 (forward_search_command, reverse_search_command): Use getc, not
3012 fgetc, for speed. FIXME, add comment about buffers that die if
3013 overrun by long line.
3015 * values.c (unpack_field_as_long, modify_field): Avoid shifting
3016 by an entire word, which is not portable, if we have a 32-bit
3017 field. (Code in dbxread.c already turns such bitfields, if
3018 aligned, into ordinary ints, but fixing this will help for other
3019 symbol formats and for future changes.)
3020 * core.c (core_open): Handle ANSI const brain death.
3021 * utils.c (vprintf): Fix varargs typo.
3023 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3025 * findvar.c (find_var_value): Handle &function better.
3026 * TODO: Document work needed on &fn and &array.
3027 * printcmd.c (print_address_symbolic): New arg is the prefix
3028 to print if a name is printed.
3029 (print_address_demangle): Honor "set print address" now.
3030 Use new arg above to improve spacing of output.
3031 * valprint.c (val_print): When printing function pointers,
3032 print symbolic form too.
3033 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
3035 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3037 * core.c (memory_error): Reword error msg to mislead less.
3039 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
3041 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
3042 parse_partial_symbols): Use newer BFD internals (external_filehdr
3043 and external_aouthdr), byte-swap the fields that we care about
3044 before using them, and make the file header data local to
3045 read_the_mips_symtab rather than global.
3047 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
3049 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
3050 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
3052 * main.c (command_line_input): Flush stdout and stderr
3053 before every call to readline. This reportedly fixes a bug
3054 that comes up in Sys V running emacs-gdb and/or xxgdb,
3055 when stdin/out are pipes or sockets.
3057 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3059 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
3060 Avoid declaring Makefile dependencies, because GNU Make stupidly
3061 tries to update it if we do.
3063 * coffread.c: Revise for minor changes to bfd internal coff
3066 * configure: If -template= is given a relative path, make it
3067 absolute before recurring in subdirectories.
3069 * configure, configure.in, Makefile.in: Install "configure" script
3070 as replacement for config.gdb.
3071 * config.gdb, Makefile.dist, Makefile.sdir: Remove
3072 * README: Update for configure, mostly. FIXME.
3074 * Add dec3100 as equivalent to littlemips. Indicate in all host &
3075 target config files that they are for the host. When the lines
3076 get copied into the Makefile, this makes it more obvious what's
3079 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3081 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
3082 tabs, which end up in the disassembler output inadvertently.
3084 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
3086 Make it compile cleanly in an ANSI GCC2 environment.
3088 * blockframe.c: <stdio.h>
3089 * cplus-dem.c: free takes a void *, ifdef __STDC__
3090 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
3092 * defs.h (alloca): Avoid doing anything if alloca already def'd.
3093 * stddef.h, stdlib.h: Remove these files.
3094 * symtab.c: Avoid declaring qsort, close.
3095 * symfile.c: Avoid declaring close.
3096 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
3097 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
3099 Assorted other changes.
3100 * dbxread.c: include "libaout.h", not "liba.out.h".
3101 * printcmd.c (print_frame_args): Set recurse properly for
3102 indentation of struct and array parameters.
3103 * valops.c (value_cast): Allow cast to void.
3104 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
3105 single_step() in a target-independent fashion.
3106 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
3107 set up to be ready to continue. This makes us target independent.
3108 * infptrace.c (child_resume): Remove call to single_step; now
3109 can single step a SPARC target of any kind.
3111 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3113 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
3114 docn into separate sections---basically chapters, plus two loose
3115 pieces that can be configured to go in different places. This
3116 allows GNU m4 to preprocess the manual without coredumping.
3118 * Makefile.dist: tell TeX where to find texinfo.
3120 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3122 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
3123 the new target "rdl-apps.texinfo" which captures the Makefile
3124 variable that records where to find the Readline libraries.
3126 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
3128 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
3129 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
3130 * defs.h (const, volatile): Only define if not already defined.
3131 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
3133 * README: Update for release 3.95.
3134 * config.gdb: Don't create readline dir in subdir builds.
3135 * main.c: Include with "..." form for non-system include files,
3136 so "gcc -MM" for "make depend" works.
3137 Include readline files with "...h" rather than <readline/...h>.
3138 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
3140 * coffread.c: Undo minor damage done by Rich Pixley. Use
3141 different internal and external representations of COFF
3142 data structures. Use new BFD routines for swapping them in and
3144 * symfile.c (free_named_symtabs): Avoid freeing file names that
3145 are null or empty. Old i960 tools seem to produce files that
3146 claim to have empty names, causing each successive file read
3147 to blow away the previous one.
3148 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
3149 Move deferred_stores to top of file, but don't separate its
3150 #define's from its variable. Add commentary.
3151 * Makefile.dist: Fix Rich damage; undo "configure" changes in
3152 favor of keeping the (working) config.gdb. Move readline
3155 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
3157 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
3159 * infptrace.c (fetch_registers): no result, since now void.
3160 * tconfig/news: target depends on m68k-tdep too.
3162 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3164 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
3167 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
3168 applied various small fixes due to or inspired by RMS comments
3170 * doc/gdb.texinfo: finished using all RMS comments, save those for
3171 appendices on readline and cmd history (which are in other source
3174 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3176 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
3177 chapter 9; (2) documented 'break' command's menu mode for
3178 overloaded names, in response to hgs problem report C++ p-31
3180 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3182 * doc/gdb.texinfo: (1) better introductory example; (2) more
3183 consistent use of @code, @samp, @file, @kbd throughout; small
3184 cleanups to first three nodes; (3) new "Contributors" node;
3185 (4) Appendix, Renamed Commands; (5) divert specialized startup
3186 instructions to "Targets" chapter for generic manuals, while
3187 leaving them up front for manuals specific to specialized
3188 environments; (6) apply fixes from RMS comments through chapter 4.
3190 * pretex.m4: modify explanatory text slightly (and redefine
3191 "regexp") to keep GNU m4 from complaining. (It still crashes
3192 later, but one step at a time...)
3194 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
3196 * readline/readline.c (update_line): Avoid dereferencing a pointer
3197 before comparing it to its bounds. Saber caught this.
3198 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
3199 and only set PC if tgetstr returned non-null. Saber caught this.
3201 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3203 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3204 stuff for config manual) here where it counts; updated
3205 to use new subdir structure (gdb/doc/).
3207 * Makefile: generated from above via
3211 * gdbint.texinfo: added instructions on generating gdb.info* files
3212 locally for release. These are ordinary info
3213 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3214 Makefile)---but due to use of texinfo 2, can't count on makeinfo
3215 to generate these, so we distribute them already formatted.
3217 * gdb.texinfo: included full Info node and menu crud (as generated
3218 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3220 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3221 put in comments-for-future gdb.info target (one day makeinfo will
3224 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3226 * gdb.texinfo: Updated to include new or old undocumented
3227 commands, at least the following (perhaps some others I forgot to
3228 record): info f, info float, info path, info program, info s, info
3229 set, info source, info terminal, info types, info user, set/show
3231 Also covered all recent GDB command renames for v4.
3233 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3235 * mipsread.c: Rather than keeping count of how many symtabs
3236 and psymtabs we have, for sorting purposes, count them when
3237 we need to sort. This fixes bug in rereading of symbol tables.
3239 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3241 * infcmd.c: renamed "info path" to "show paths"
3242 * gdbrc.tex: documented above.
3244 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
3246 * remote.c: Fix comments.

3249 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3251 * Makefile.dist: Roll VERSION to 3.95.
3252 Fix up "saber_gdb" to work again.
3253 * saber.suppress: Update.
3255 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
3256 symtab.h, target.c, target.h: Lint.
3257 * core.c: setup and select frame after reading shared libs,
3258 else reading shared libs will clobber them. Lint.
3259 * utils.c (error): Force out any buffered wrap text.
3261 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
3263 * remote.c: Remove decls of memory_insert_breakpoint
3264 and memory_remove_breakpoint, no longer used. (Suggestion of
3267 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
3268 to make it easier to interface to "configure"'d libraries.
3270 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
3272 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
3273 aliases for set/show print.
3275 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3315 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
3317 * mtrace.c: Don't typedef things like size_t, just #define them.
3319 * coffread.c [TDESC]: #if 0 out references to coffsyn.
3321 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
3322 tm-88k.h: Define EXTRA_SYMTAB_INFO.

3325 dc_dcontext_t not int.
3327 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
3329 * coffread.c [TDESC]: Move setting of debug_info from
3330 coff_symfile_read to find_linenos and make it work with BFD.
3332 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
3334 * signame.c: Cast const char* to char* when assigning to sys_siglist.
3336 * utils.c (strsave): Make arg const char* not char*.
3338 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
3339 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.

3362 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
3363 (This still doesn't seem to make MIPS bkpts work.)
3364 * mipsread.c: Remove dup "Reading symbol data..." msg.
3365 (symbol_file_command, add_file_command): Remove, obsol.
3366 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
3367 Wrap output appropriately.
3368 * stack.c (locals_info, catch_info, args_info): Check
3369 selected_frame rather than target_has_stack or coredumping.
3370 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
3371 enums appropriately.
3373 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3846 * dbxread.c (end_symtab): Ditto.
3847 * expread.y (block): Ditto.
3848 * mipsread.c (throughout): Ditto.
3849 * symmisc.c (free_named_symtabs): Ditto.
3851 * symtab.c (list_symbols): Process the first symbol of the
3852 static psymbols list.
3853 (types_info): Restore this function from its untimely #if 0.
3854 It's not perfect, but it is better than nothing.
3855 (_initialize_symtab): Restore "info types".
3857 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3859 * m68k-stub.c: Remote stub for 680x0's, created from
3860 rem-m68k.shar (which is removed).
3861 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3862 Remove RCS log stuff now that we use CVS and it blows our diffs.
3864 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3866 * symmisc.c (free_named_symtab): Make it work, in its current
3867 kludgy fashion. Change result to indicate if we blew away bkpts.
3868 * dbxread.c (end_symtab): Accumulate result from
3869 free_named_symtab and print warning if we blew user's state.
3870 * symfile.h: free_named_symtab now returns an int.
3872 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3874 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3875 is the first symbol read, even if not mainline.
3876 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3877 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3878 (set_section_command): New command ("section xxx yyy" -- should
3879 be renamed to "set section xxx yyy" FIXME) which sets the
3880 base address of a section of the exec file, overriding the
3881 virtual address that BFD reports.
3883 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3885 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3886 load symbols at any address while examining an exec file.
3888 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3890 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3891 for printing the float info is host-dependent, not
3892 target-dependent. FIXME.
3893 * i386-pinsn.c: Move #includes to top, remove useless ones.
3894 * i386-tdep.c: Don't bother including <.../reg.h> since we
3895 don't use it (and it doesn't exist on host systems).
3897 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3898 Convert negative numbers properly.
3899 (ieee_test): Make numbers really random; fix format arg.
3901 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3902 * core.c (core_detach): Unpush core_ops, which might not be on
3903 top. We used to just pop the top, which broke things. Don't
3904 need dont_repeat() any more.
3905 (core_file_command): Psst! Don't repeat it.
3906 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3907 * expprint.c (print_subexp): Avoid switch fallthru on
3908 BINOP_ASSIGN_MODIFY, so we can print += and such.
3909 * frame.h: Fix typo.
3910 * inflow.c (kill_command): After killing inferior, print our
3911 current frame in the core file, if we have one.
3912 (generic_mourn_inferior): When inferior dies, either select
3913 the current frame (in the new target, e.g. core file), or
3914 set both the current and selected frames to NULL.
3916 Changes from Peter Schauer.
3918 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3920 * Make all file names fit in 14 characters (sigh and damn!):
3921 mv hp300hpux-xdep.c hp300ux-xdep.c
3922 mv symmetry-xdep.c symm-xdep.c
3923 mv symmetry-tdep.c symm-tdep.c
3924 mv convex-opcode.h convx-opcode.h
3925 mv tm-vxworks960.h tm-vx960.h
3926 mv tm-vxworks68.h tm-vx68.h
3927 mv Makefile.srcdir Makefile.sdir
3928 mv gdb-int.texinfo gdbint.texinfo
3929 mv remote-sa.m68k.shar rem-m68k.shar
3930 mv remote-multi.shar rem-multi.shar
3931 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3932 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3933 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3936 * command.c (user_info_1, user_info): New command for listing
3937 the user-defined commands.
3939 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3941 * dbxread.c (really_free_pendings): Clear file_symbols
3942 and global_symbols after freeing them; otherwise, running
3943 this function twice (if it appears twice on the cleanup
3944 chain), we try to free things twice.
3946 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3947 based on text_addr (the address of text in core), not on addr (the
3948 offset between text in the .o file and in core). This change
3949 is from Peter Schauer.
3951 * main.c: Define ALL_CLEANUPS as a cast of zero.
3952 (return_to_top_level): Use it.
3953 (main): Do all cleanups after each command run as part
3954 of the gdb startup sequence. Also do all cleanups before
3955 entering the command loop, and every time we exit the command
3956 loop and reenter. Before, the cleanups from the startup sequence
3957 were being left undone until the first error!
3958 (command_loop): Rename do_nothing cleanup to command_loop_marker
3959 so we can see it easily when examining the cleanup chain.
3960 (init_signals): Add another do_nothing for signal handling.
3961 (quit_command): Only try to kill target if it has execution.
3962 Problems in the target stack got us into a state where
3963 inferior_pid was nonzero but none of the targets had execution.
3964 In this state you couldn't exit gdb.
3966 * dbxread.c: Two changes from Peter Schauer.
3967 (echo_command): Fflush output after an echo command.
3968 (show_history): Pass all args to cmd_show_list.
3970 * utils.c (init_malloc): Call mtrace to turn on tracing
3971 if the environment variable MALLOC_TRACE is set to a file name.
3972 * mtrace.c: Add source file which provides a log of every malloc,
3973 free, and realloc to a trace file.
3974 * mtrace.awk: Add source file which analyzes the trace file.
3975 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3976 (VERSION): Roll to 3.94.3.
3978 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3979 (check_duplicates): Don't bother with watchpoints.
3980 (set_raw_breakpoint): Comment about danger of this routine.
3981 (watch_command): Parse and eval all args before calling
3984 * solib.c (find_solib): Avoid error in referencing memory to
3985 see if any more shared libraries have been added. This is
3986 particularly useful if the target has terminated. Bug reported
3989 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3990 in bringing up 3.94.2 on the Sun-3.
3992 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3993 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3994 expression (in scope) before reenabling watchpoint.
3995 * signame.c (init_sigs): Add missing declaration of i, fix
3996 sys_siglist declaration.
3997 * source.c (list_command): Fixed range computation to use
3999 * stack.c (backtrace_command): Do not allow command if target has
4000 no stack, print informative error message.
4001 * target.c (target_command): Do not write into command line
4002 because this fails if the target command is used in a user defined
4003 command. [This change was enhanced by gnu to support any-
4004 unique-prefix matching on target names.]
4005 * valops.c (value_struct_elt): Avoid infinite loop on an
4006 erroneous attempt to print the member of function (try p main.p).
4008 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4010 * expread.y (name_no_typename): Avoid reduce/reduce errors
4011 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
4012 Since the GDB parser really doesn't use name_no_typename in a
4013 name-only context, the parser can't tell the diff between
4014 names and numbers here. Avoid allowing a name_no_typename
4015 to be a NAME_OR_*INT to resolve the conflict.
4017 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
4019 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
4021 * valprint.c (val_print_fields): bitfield printing didn't handle
4022 byte order. Indirect through a few more fns to cope.
4024 * values.c (modify_field): also cope with byte order.
4026 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
4028 Cleanup for release 3.94.2:
4030 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
4031 include files. Roll version to 3.94.2.
4033 * coffread.c (init_stringtab): Read length into unsigned char
4034 array before swapping; don't assume 32-bit longs.
4036 * target.c (target_info): Don't bother with get_sym_file, just use
4037 the symfile global variable.
4038 * symtab.h, symfile.c (get_sym_file): Delete it.
4040 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
4041 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
4042 (read_type): Replace one more error() with complain().
4044 * mipsread.c (parse_partial_symbols): Replace printf with complain.
4046 * i960-tdep.c: Fix copyright attribution.
4048 * config.gdb: Quote all backquotes in doublequotes. You can
4049 quote me on that. BSD 4.4 shell found this one.
4051 * infptrace.c (throughout): The third argument to ptrace is an
4054 * infrun.c (wait_for_inferior): When program has terminated, we
4055 have to call target_terminal_ours before we pop that target off
4056 the stack (e.g. before a call to target_kill or
4057 target_mourn_inferior). This fixes problem where a program
4058 terminates, then GDB stops for (tty output) and you have to type
4059 "fg" to the shell to resume it. FIXME: This code for what to
4060 do after termination really should be in normal_stop instead.
4062 * gdbcore.h (read_memory_check): Change declaration; it changed
4065 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4066 4.4 prereleases, this avoids a bug in their sgtty compatability
4068 * remote.c: Use terminal.h rather than hand-rolling the same.
4070 * signame.c, signame.h (psignal): Arg is unsigned, not int.
4071 * utils.c (strsave, strstr): Fix arg types.
4072 * valprint.c (val_print): lint
4074 MIPS symbol table support from Per Bothner:
4076 * symfile.c (symtab_fns): Remove initializer table that needs to
4077 be hacked for each new symbol file format supported.
4078 (add_symtab_fns): New function, chains symbol table
4079 handlers into the global list.
4080 (symfile_init): Search this list.
4081 * symfile.h: Add next pointer, declare add_symtab_fns.
4082 * coffread.c (_initialize_coffread): Call add_symtab_fns.
4083 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
4085 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
4086 symbol *). Thus, we no longer need the hack to trash
4087 pst->filename. Good, since that hack confused code in symfile.c!
4089 (reorder_symtabs, destroy_all_symtabs): Removed static
4090 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
4091 Instead, the latter now uses a temporary array (stack-allocated
4092 from an obstack, and then freed).
4094 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
4095 haven't been set in the outermost stBlock of a procedure. This was
4096 a problem with f77 binaries on Ultrix 4.?.
4098 (new_symtab, new_symbol, new_type): Continue changing code to use
4099 obstacks more and otherwise conform to dbxread internal style.
4100 Made the free_code of symtabs be free_linetable (as in dbxread)
4101 instead of free_contents. This implies memory leaks when reading
4102 a new symbol table, until the conversion is finished. Did change
4103 (struct symbol) and (struct type) to be allocated on the
4104 symbol_obstack. Blocks and blockvectors are among the things
4107 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
4108 tested much, but it solved one problem (reported by Meissner), and
4109 cleans up some other things. The problem happened when an
4110 included file contains actual code (functions) and not just
4111 definitions. The mips coff is a little inconvenient there, since
4112 it may cause a procedure to be mapped to the wrong psymtab.
4114 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
4115 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
4116 this will need work for the new core paradigm.
4118 Opcode patches from the net:
4120 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
4121 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
4122 missing altogether - they are added here. From Bruce Bauman.
4123 * mips-opcode.h: The low mask for C0 instructions was too small.
4124 From Garrett Lau. I modified the fix to check the entire 32-bit
4127 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
4130 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4132 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
4134 * dbxread.c (read_type): Pointer subtraction (value_sub in
4135 valarith.c) sometimes failed because the types of the
4136 pointers being subtracted were not identical.
4137 These differed because dbxread.c was allocating pointer types
4138 using dbx_alloc_type+smash_to_pointer_type instead of
4139 lookup_pointer_type. I failed to find a justification for the
4140 former, so I changed it to use the latter. Similarly, I
4141 replaced smash_to_function_type by lookup_function_type,
4142 and smash_to_reference_type by lookup_reference_type.
4144 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
4145 _initialize_mipsread): corresponding changes.
4147 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
4149 * source.c (mod_path): Do tilde_expand on each component of the path,
4150 rather than on the (list of) paths as a whole.
4151 (print_source_lines): Set first_line_listed in addition to
4152 current_source_symtab and current_source_line. If the source was
4153 not findable, after a "dir" command to fix the problem,
4154 a "list" would get the wrong lines.
4156 While I was there... (gnu):
4158 * dbxread.c (read_type): Change error to complaint.
4160 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4162 First attempt at detailed understanding of symbol table memory alloc.
4164 * dbxread.c (dbx_symfile_read): Free our string table if we
4165 aren't the mainline. Free the "info" struct since we're done with
4167 (init_psymbol_list): Free any previously allocated psymbol lists.
4168 (): FIXME: Should realloc-down the psymbol lists when done reading
4169 the main symbol file?
4171 * symmisc.c (free_symtab): Free fullname field too.
4173 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
4174 (REGISTER_ADDR): Make result type unsigned int.
4176 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
4177 define REGEX must also define REGEX1 (its dependency).
4179 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
4181 * tconfig/i960: No longer works, points you at vxworks960 or
4184 * xgdb.c, XGDB-README: Remove file. Users can get the much
4186 * Makefile.dist: Remove all trace of xgdb.
4188 * breakpoint.c (breakpoint_1): Pass demangle arg to
4189 print_address_symbolic.
4190 (clear_breakpoints): Remove unused function.
4191 (breakpoint_re_set_one): Guts of breakpoint_re_set.
4192 (breakpoint_re_set): Use catch_errors to do them all anyway.
4194 * gdb-int.texinfo (Host versus Target): Add section on what is
4195 a "host" feature versus what is a "target" feature.
4197 * infcmd.c (path_command, path_info): Handle the PATH variable
4198 (object search path) as conveniently as the source search path.
4199 * environ.c (set_in_environ): Set some vars in GDB's environment,
4200 in addition to the child's. PATH, G960BASE, G960BIN for starters.
4201 * source.c (mod_path): New function, from guts of
4202 directory_command, modifies a path. Used by path_command.
4203 (directory_command): Call it.
4204 * defs.h (strsave): Declare.
4206 * utils.c (sevenbit_strings): Add new printing option.
4207 (printchar): Use it.
4208 (strsave): Provide this handy helper routine.
4209 (set_width_command): Rename set_screen_width_command.
4210 (_initialize_utils): "set screen-width" => "set width";
4211 "set screen-height" => "set height"; add sevenbit-strings.
4213 * infcmd.c (do_registers_info): Print floating point registers
4214 in raw hex as well as float format, regardless of whether it is
4215 a "virtual" convertible register.
4216 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
4217 regs as a double, just in case it's being used that way.
4218 * values.c (unpack_long): Comment on array/function coercion.
4219 (unpack_double): Argument is in target byte order now. For
4220 integer arguments, just call unpack_long and float the result.
4221 * m68k-tdep.c: include defs.h for "const" handling.
4222 * remote-nindy.c: Use ieee-float stuff.
4223 (nindy_fetch_registers): Unpack double regs to host double, then
4225 (nindy_store_registers): Pack extendeds to host double, flip
4226 around by misusing unpack_double, send as target double.
4228 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
4229 zero, as when stopped at the first instruction of a process.
4231 * blockframe.c: Fix filename in comment (param.h => tm.h).
4232 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
4233 * tm-68k.h: Fix typos.
4235 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
4237 Changes from a bringup on the DEC Vax under Ultrix 4.0.
4239 * coredep.c (fetch_core_registers): Pass end-address of register
4240 section to register_addr as expected. Don't call supply_register
4241 if we'd just pass it garbage.
4243 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
4245 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
4247 * target.c (push_target, target_info): Cast enums to int for < or
4250 * stack.c (print_frame_info): Identify source file & line
4251 even if we can't print it.
4253 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
4255 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
4257 Clean up IEEE floating point support.
4259 * ieee-float.h: New file.
4260 * ieee-float.c: Write real routines to convert between host
4261 doubles and various target IEEE extendeds.
4262 * m68k-xdep.c: Eliminate assembler code for extended floats.
4263 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
4264 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
4265 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
4266 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
4267 double_to_ieee_extended.
4268 * i960-tdep.c: Define ext_format_i960.
4269 * m68k-tdep.c: Define ext_format_68881.
4270 * sparc-tdep.c: Define ext_format_sparc, though unused.
4271 * Makefile.dist (HFILES): Add ieee-float.h.
4272 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
4275 Obsolete the "coffstrip" program in favor of using BFD's strip.
4277 * nindy-share/coffstrip.c: Remove file.
4278 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
4279 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
4280 * tconfig/nindy960: Remove reference to coffstrip.o.
4282 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
4284 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4286 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
4287 * dbxread.c: Remove static symfile_bfd.
4288 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
4290 * inftarg.c (child_detach): Pop the child_ops vector if the
4291 detach is successful.
4292 * remote-nindy.c (nindy_create_inferior): Don't push a new
4293 nindy_ops since nindy uses the same one for execution and memory
4295 * core.c (core_ops): Use child_attach and child_create_inferior
4296 rather than default attach and create_inferior functions.
4298 Handle floating point registers in core files.
4300 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
4301 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
4302 This version untested since BFD doesn't yet support sun3 core
4304 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4305 conventions. Fix comments and style. This version has not
4306 been compiled yet, since we have no HP inhouse.
4307 * core.c (get_core_registers): Look for two sections, ".reg"
4308 and ".reg2", and pass both to fetch_core_registers sequentially.
4310 Revise directory path yet again.
4312 * source.c (forget_cached_source_info): Not static any more.
4313 (init_source_path): New default source path is "$cdir:$cwd".
4314 (dir_command): Handle variable arguments ($cdir, $cwd).
4315 (source_info): Print "Compilation directory" rather than
4316 "Originally compiled in" to remind people of $cdir.
4317 (openp): If the path contains $cwd, use current directory.
4318 (open_source_file): If compilation directory is known, replace
4319 first $cdir in path with the compilation directory.
4320 (print_source_lines): Even if we can't print the lines, set the
4321 current symtab and line for future commands like "info source" or
4322 "breakpoint". Also, error message now contains the file name,
4323 line number, and file access error message.
4324 (_initialize_source): Fix help text to describe changes.
4325 * main.c (cd_command): Forget cached source info when we chdir.
4326 * utils.c (strstr): Add simple implementation.
4328 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
4330 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4331 Byte-swap COFF symbol tables if necessary when reading them in.
4332 Use complain() to replace error message in one spot. Needs
4333 corresponding change in bfd/coff-code.h to make some symbol
4334 swapping routines non-static.
4336 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4338 Merge changes from Eirik Fuller, for UTek.
4340 * defs.h (errno): Add declaration.
4341 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
4342 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
4343 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
4344 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
4345 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
4346 declarations of errno.
4348 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4350 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4351 <rpc/rpc.h> and <rpc/types.h>.
4353 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4355 * i960-tdep.c (examine_prologue): Add new argument limit,
4356 which stops the scan at the end of the prologue, or at the PC.
4357 This fixes a problem where it walks down into the code for the
4358 user's statements if that code looks like function prologues.
4359 Mark Fox and I have been bouncing this code back and forth, making
4360 small changes to it. Callers changed to match.
4362 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4364 Cleanup for gdb-3.94 release final:
4366 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4367 the .c files from vx-share and nindy-share, from the various
4368 macros, since they are not found via ALLDEPFILES.
4369 (SFILES): Add tm-i960.h.
4370 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4371 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
4373 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
4374 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
4376 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
4378 * am29k-tdep.c: Add contribution line.
4379 (examine_prologue): Cache information about function prologues in
4380 the misc-function-vector to avoid lots of references over the
4381 serial line while examining instructions.
4383 * core.c (core_close): New function made from cleanup_core.
4385 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4386 remote-vx.c, remote.c, target.c, target.h,
4387 Update target_ops vector to add attach, close, and load entries.
4388 Use add_syms_addr_command, not add_file_addr_command, for
4389 add_file. Break out close routine from existing code.
4391 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4392 they are in an obstack.
4393 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4395 (define_symbol): Add symbol type parameter; change callers;
4396 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4397 it to influence the symbol class on the i960.
4398 (define_symbol): Swap LOC_CONST's into target byte order.
4400 * exec.c (exec_close): New function.
4401 (exec_file_command): Call it.
4403 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4404 Fix byte order of frame pointer.
4405 (read_var_value): Result of 0 if var's value can't be found,
4406 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4407 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4408 (locate_var_value): Use read_var_value and use its lazy address
4409 as the location of the var's value. Lint.
4411 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4414 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4415 obsolete Intel versions in favor of vxgdb versions.
4416 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4417 code dealing with byte order of values, which Intel did in host byte
4418 order rather than gdb-4's target byte order.
4419 (i960_frame_chain_valid): Move to nindy-tdep.c.
4420 (examine_prologue, skip_prologue, frame_find_saved_regs,
4421 frame_args_address, leafproc_return, saved_pc_after_call,
4422 pop_frame): Add vxgdb versions from Mark Fox.
4423 (examine_prologue, frame_struct_result_address): Add code
4424 to deal with the saved value of G13 (struct return address
4426 (frame_args_address): Modify Mark's version to prefer the
4427 saved value over the current value in the topmost frame.
4428 Cache result in the frame info to avoid performance hair in
4430 (print_fault): Add gdb960 code for printing faults.
4431 (_initialize_i960): Actually call check_host.
4433 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4434 add stub routines. FIXME, these currently just return zero!
4436 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4437 (attach_command): Call target_attach, not target_open, now.
4439 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4440 (child_attach): Rename from child_open.
4441 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4442 don't confuse it with a zero step_resume_break_address.
4444 * inftarg.c (child_detach): Eliminate inferior_pid test.
4445 (child_files_info): Clean up message a bit.
4446 (child_ops): Use child_attach, not child_open, to attach.
4448 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4449 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4450 findvar.c to here, since it depends on the contents of the
4451 shadow_contents of breakpoints, but keep if #if 0 since it is
4454 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4457 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4458 (ptype_command, display_command): Eliminate have_inferior_p and
4459 have_core_file_p in favor of target_has_stack or
4460 target_has_execution.
4461 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4462 code for actually finding the values of arguments, though we still
4463 keep track of the maximum stack offset for use in printing unnamed
4464 arguments. Handle missing FRAME_ARGS_ADDRESS.
4466 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4467 (struct nindy_regs): Define registers passed to/from nindy.
4468 (nindy_fetch_registers, nindy_store-registers): Translate between
4469 nindy and GDB formats for the registers.
4470 (dcache_init): Statically allocate the cache, since it was being
4471 allocated by a malloc that was never freed anyway.
4472 (nindy_create_inferior): Error, not core dump, if no exec file.
4473 (nindy_before_main_loop): Use target_load, not target_add_file.
4475 * remote-vx.c (net_load): Specify large timeout for load
4476 requests. Allow user to break out with INTERRUPT.
4477 (net_break): Remove useless code, clean up. Change callers.
4478 (parse-args, skip_white_space, find_white_space): Clean up arg
4479 parsing to cope with quoted strings.
4480 (net_wait, net_quit): Never call error, just return status.
4481 (vx_read_register, vx_write_register): Cleanup status checking.
4482 #ifdef the code based on which CPU we are using (960 or 68k),
4483 FIXME, this should be completely general but it isn't yet.
4484 (vx_xfer_memory, vx_resume): Cleanup status checking.
4485 (vx_run_files_info): Improve message.
4486 (vx_load_command): Renamed from vx_add_file_command. Allow load
4488 (net_ptrace): Remove unused routine.
4489 (vx_wait): Adopt code from vxgdb960 to cope with broken
4490 connections to target machine and prompt to disconnect. Remove
4491 debug printouts. Map some EVENT_'s to SIGnals.
4492 (add_symbol_stub, vx_open): Print names of object files we found,
4493 and "ok" if we read their symbols OK. Clarify output in general.
4494 (vx_attach, vx_detach, vx_kill): Add these commands.
4495 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4496 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4497 "info files" output, and create_inferior, since we already have
4500 * stack.c (frame_info): Replace Frame_unknown with 0.
4501 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4502 (return_command): Pop until the PC matches as well as the FP,
4503 so it works even if the FP is shared with another function,
4504 as in "frameless" or "leaf" procedures.
4506 * symfile.c (load_command): renamed from add_file_target_command.
4507 (add_syms_addr_command): renamed from add_file_addr_command.
4508 (add_syms_command): Stub to call target_add_syms.
4509 (_initialize_symfile): Change command names and descriptions,
4510 add-file => add-syms, and load from alias to its own command.
4512 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4513 maybe_kill_then_create_inferior): Default for attempts to start
4514 a process, if one is already running, is to ask about killing
4515 it and retry if yes.
4516 (upstack_create_inferior): #if-0 it, strata obsolete it.
4517 (push_target, unpush_target, pop_target): to_close() a target
4518 before unstacking it.
4519 (target_info): Renamed from target_files_info.
4520 (_initialize_targets): Rename "i files" as "i target", accessible
4523 * target.h: Improve comments about the target_ vectored routines.
4525 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4526 Convert commenting style to standard GNU style.
4527 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4528 (SKIP_PROLOGUE): No longer a no-op.
4529 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4530 (*_REGNUM): Sort register numbers.
4531 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4532 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4533 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4534 are now 10 byte extendeds, not 8 byte doubles.
4535 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4536 for nindy versus vxworks targets. FIXME, this should possibly go
4537 in the target vector.
4538 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4539 frame_saved_regs and arg pointer with each frame.
4540 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4541 (FRAME_ARGS_ADDRESS): Use cached result.
4542 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4543 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4544 (PRINT_RAMDON_SIGNAL): Call print_fault.
4545 (POP_FRAME): Now works.
4547 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4548 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4549 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4550 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4553 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4554 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4556 * valarith.c (value_subscripted_rvalue): Avoid handling
4557 floats and doubles specially; it gave alignment errors. Lint.
4559 * valops.c (value_of_variable, value_of_this): Error if unknown
4562 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4563 to avoid alignment problems.
4564 (value_print): Handle unknown value address.
4565 (cplus_val_print): Two args are ignored; remove them. Change caller.
4566 (val_print): Use unpack_long rather than pointer-deref.
4569 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4570 to avoid alignment problems.
4571 (value_being_returned): Error if return value unknown.
4572 (set_return_value): Add bogosity warning, FIXME. *
4574 * TODO: A woman's work is never done.
4576 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4577 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4578 Add ieee-float.o to OBS.
4579 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4580 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4581 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4583 Changes to generalize the VxWorks RPC protocol slightly, to handle
4584 i960 as well as 68000.
4586 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4587 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4588 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4589 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4590 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4591 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4592 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4593 so they will move in target byte order rather than network
4594 byte order (happens to be the same).
4596 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4598 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4600 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4603 Add contribution lines to various files, showing where they
4606 * breakpoint.c (break_insn, check_break_insn_size,
4607 read_memory_nobpt): Remove to mem-break.c.
4609 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4612 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4613 entry has bad register number. This change is not
4614 tested in this release, FIXME.
4616 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4619 * value.h: Force value's contents field to be aligned to hold
4620 at least a double or a long long (if supported). This avoids
4621 doing bcopy's in and out of the contents field.
4623 (step_1): Avoid coredump under obscure circumstances when we
4626 * symtab.h (misc_info): Add field to misc function vector for
4627 any kind of cached information the target code desires. AMD
4628 29000 uses this to avoid repeating examine_function_prologue's.
4630 * coffread.c: Lint. Remove static symfile, read_section_header.
4631 core.c (have_core_file_p): Lint: remove.
4632 expprint.c (print_subexp): Lint.
4633 infptrace.c, valops.c, valprint.c: lint.
4635 Roll in changes from vxgdb-5.0.1:
4637 * symtab.h: Comment byte order of each address class. Add
4638 LOC_LOCAL_ARG for frame-relative args (960).
4639 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4640 symtab.c, symmisc.c: ditto.
4642 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4644 * remote.c (remote_resume): Error if resume with a signal.
4646 * symfile.c (prim_record_misc_function): Clear misc_info.
4647 (fill_in_vptr_fieldno): Check stub type of arg.
4649 * valops.c (value_cast): Avoid looking up names of types whose
4650 name we don't know, to prevent coredump. Sun CC produces typedef
4651 rtx and the name of *rtx is zero...
4653 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4655 Roll in changes from final AMD 29000 port (Tiemann).
4657 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4658 for ../include/a.out.encap.h. This might not work now that BFD
4659 is separately compiled. Instead, BFD support for encap will have
4660 to translate machine type 29k into the right COFF_MAGIC.
4662 * infcmd.c: Remove references to inferior_pid that aren't used
4663 in actual ptrace calls; use target_has_execution, etc.
4664 (have_inferior_p): Remove function.
4665 (program_info): Print target info rather than "process number";
4666 avoid gratuitous messages unless from_tty.
4667 (run_stack_dummy, finish_command): Set proceed_to_finish.
4668 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4669 main.c: Lint. Lose have_inferior_p().
4670 inferior.h (have_inferior_p): Remove, lint.
4671 (proceed_to_finish): Add flag to ask that all regs be saved
4672 by normal_stop, for the few commands that need it, speeding up
4673 serial I/O. Add comments to stop_registers.
4675 * remote-eb.c: Remove newline from breakpoint message we grep
4676 for. Never time out when running the user program.
4680 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4682 Roll in changes from vxgdb-5.0.1:
4684 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4685 symbol in its raw form, we are processing an unlinked ".o" file.
4686 See if the target environment has assigned it an address, using
4687 target_lookup_symbol (VxWorks does), and enter it into the symtab
4690 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4691 68k versions for a simpler version that assumes zero FP at bottom.
4692 Fixes bug of truncated stack reports.
4694 * target.h (target_lookup_symbol): Define this routine's args
4695 and result, finally.
4697 * target.c (nosymbol): Default routine for target_lookup_symbol.
4698 (target_default): Default lookup_symbol and call_function too.
4699 (files_info): Only print has_all_memory warning if a non-dummy
4702 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4703 vx_convert_from_virtual): If target does not have floating point,
4704 zero register "values", and avoid doing cross-net conversions.
4705 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4706 (vx_open): Rearrange code that attaches to target and reads
4707 symbols for all loaded modules, to work if some of the modules
4708 are not accessible. Add symbol_stub() and add_symbol_stub()
4709 as callbacks from catch_errors(). Allow connect attempt to be
4710 interrupted painlessly with ^C (FIXME, there are still some bugs
4711 if the interrupt happens during symbol reading.). Print
4712 final message with puts_filtered, since symbol messages are
4717 * main.c (catch_errors): Only print errstring if non-null.
4718 (command_loop): Avoid an ioctl per command to test ISATTY.
4720 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4721 (vx_xfer_memory): Return correct result!
4722 (vx_files_info): Indicate whether target has float or not.
4723 (vx_lookup_symbol): Complain, not error, if target gone.
4724 (vx_open): Print "Connected" msg before disabling immediate-quit.
4725 [FIXME: lookup_symbol and vx_open changes need testing.]
4727 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4728 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4729 contributor lines and update copyrights to 1991.
4731 Changes from an attempted H-PUX host port:
4733 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4734 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4735 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4736 * remote-vx.c: include <sys/time.h> for HPUX.
4737 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4738 "core_file_command" routine to BFD regime. May not work yet.
4740 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4742 * xgdb.c: Replace X10 version with some VJ version.
4743 (FIXME: Its copyright assignment is not on record.)
4744 * xgdb.c: Update include files to X11R4 (Xaw crud).
4745 (xgdb_display_source, create_text_widget): fix call to
4746 get_filename_and_charpos. Rewack source window stuff for X11R4
4747 (gleaned from include files, and "nm's" of binary libraries, since
4748 I had no doc available).
4749 (append_selection, append_selection_word): Disable with FIXME
4750 since R4 changed interface here.
4751 (create_buttons): Add back the old set of buttons.
4752 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4754 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4755 Roll VERSION to 3.94 (not yet final though).
4757 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4759 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4760 obstack_int_grow, obstack_int_grow_fast): Eliminate
4761 cast on left of assignment, which gives MIPS cc fits and is
4764 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4765 F_ALIAS. Use printf, not fprintf, when not passing a file
4767 (compare_opcodes): Check that identical instructions have
4768 identical opcodes, complain otherwise.
4770 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4771 was reported by Roland McGrath.
4772 (unimp): Only match if exactly zero instruction. (Roland)
4773 (branches and traps): Generate all variations of these
4774 instructions with macros, based on a single call that defines
4775 each condition name and its binary representation.
4776 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4778 * valprint.c (val_print_fields): Take, and use, format parameter.
4779 This means that "p/x struct" again prints the elements in the
4780 desired format. Changed callers.
4782 * stack.c (frame_info): Use filtered output, and indicate wrap
4783 points. Remove kludgy formatting designed to avoid line wrap.
4785 * utils.c (wrap_here): If the line is already full (because
4786 we had printed a long indent or long wrapped string), do an
4787 immediate newline-and-indent.
4789 * m68k-pinsn.c (print_insn_arg): Bugfix from
4790 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4791 instruction is incorrectly disassembled as bkpt #8.
4793 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4794 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4795 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4796 and then will dump core (sometimes). I traced it back to an
4797 uninitialized symfile_name in psymtab_to_symtab.
4798 (const_vol_complaint): Add quotes to message.
4799 (define_symbol): Only believe line number if gcc_compiled.
4800 Avoid allocating symbol if we will not return it.
4802 Add target strata support so that newly established targets go
4803 into their right place in the target stack (e.g. a new exec file
4804 doesn't wipe out the ability to access the running process).
4806 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4807 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4808 and initialize it properly in all the targets.
4810 * target.h: Document strata. Change return type of push_target.
4812 * target.c (nomemory): new function for dummy memory access.
4813 (tcomplain): Rename complain, now also used in symfile.c.
4814 (push_target): Push targets within strata. New return value shows
4815 whether new target is on top of stack or not. Always keep dummy
4817 (target_files_info): Ignore dummy target.
4819 * core.c (core_open): Warn user, and skip accessing file, if the
4820 core target is not the topmost target in the stack.
4821 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4824 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4825 target_ops, it doesn't belong there since we have no regs there.
4826 Change name of target from machine => memory to clarify.
4828 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4830 * Freeze version 3.93 for release.
4832 * Makefile.dist: Handle vx-share and nindy-share subdirs
4833 properly when building gdb.tar.Z.
4835 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4836 printed in various places, so I could change just one copy.
4838 * dbxread.c, coffread.c: Change references to bfd->iostream
4839 to cast to FILE *, now that BFD avoids needing types defined
4840 in other header files.
4842 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4844 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4845 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4846 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4847 (actually gcc -Wall).
4849 * dbxread.c: Remove first_global_sym, last_global_sym, since
4850 they are never referenced.
4852 * defs.h (baud_rate): Declare.
4853 main.c: Define it, and add the -b option to set it.
4855 * gdb-int.texinfo: Add text on how to define a new host or target
4856 architecture, prompted by Per Bothner's questions about MIPS
4859 * gdb.texinfo: Document "complaints". Change doc of -q since
4860 gdb no longer prints the copyright and blurb if you specify a file
4861 name to be debugged (just like Emacs). Add doc for Nindy-specific
4862 command line flags for specifying target serial port and such.
4863 Update copyright to 1991.
4865 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4866 has taken over for us the job of ripping up executable files. The
4867 crud caused Per Bothner's port to not compile.
4869 * infrun.c (normal_stop): Avoid printing "Program exited
4870 normally" if we are in batch mode. This allows a GDB which
4871 executes a program on a target system, to behave like a Unix
4872 command (input from stdin, output to stdout, no extraneous
4875 * main.c (main): Allow additional machine-dependent command line
4876 options to be specified with the ADDITIONAL_OPTIONS,
4877 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4878 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4879 processing to occur just before the main loop with
4880 BEFORE_MAIN_LOOP_HOOK.
4881 (main): If a "core file" argument is specified, and it is not a
4882 core file, try it as a process ID to attach.
4883 (symbol_completion_function): Attempt to cope with
4884 "show screen-" TAB, not very successfully. This needs more work,
4886 (batch_file): New function, returns whether we are reading
4887 commands from an interactive tty on stdin, or from somewhere else.
4888 Called by normal_stop since it doesn't get from_tty passed down
4889 to it like many commands do.
4891 * remote-nindy.c: Handle command line options for nindy
4893 (nindy_before_main_loop): Prompt user for tty name if they
4894 don't specify it before getting to the interactive command loop.
4896 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4897 and -r command line options. Also add hook before main loop
4898 to make it easy to specify a tty.
4900 * TODO: More things to do, one done.
4902 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4904 * dbxread.c: Make complaint() calls pass pointer, not struct.
4905 Add complaints about badly formatted C++ type information
4906 (const/volatile indicator, and parse errors resulting in
4907 error_type). Fix C++ virtual member fn comment.
4908 (read_struct_type): Avoid bumping pointer if we got a parse
4909 error; this prevents our walking beyond the end of a string.
4910 Terminate loop on null char as well as semicolon.
4911 (process_one_symbol): Fix the LBRAC fix so that it uses the
4912 last previous SLINE, FUN, or SO record's PC address. C++ debug
4913 symbols did not have SLINE records in a useful order compared
4914 to the LBRAC records.
4915 (define_symbol): Handle "catch" records.
4917 * symtab.c (check_stub_type): Added new complain
4918 `stub_noname_complain' and added a consistency check to
4919 keep the debugger from crashing when finishing from an
4920 exception frame. A real fix will be needed later.
4922 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4924 * infcmd.c (attach_command): Make global.
4926 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4927 but make them easy to comment out. Perhaps later they should
4928 be enabled by what CPU you configure for? FIXME.
4929 (VERSION): Roll to 3.93.
4930 (pinsn.o): Remove rule for obsolete file.
4931 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4933 Run down a problem that manifested by printing the wrong function
4934 name in stack traces of read_ofile_symtab. Turned out that the
4935 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4936 the LBRAC symbol with an address in the *data* segment, which
4937 blew our binary search through the blocks.
4939 * dbxread.c: Use the complain() facility consistently to bitch
4940 about problems in the symbol file we are reading.
4941 (finish_block): Add code to check the nesting of the blocks;
4942 complain and Procrust them to fit if wrong.
4943 (make_blockvector): Check the order of the blocks, complain
4944 [but don't cope] if wrong.
4945 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4946 symbols to be sure their PC value is greater than the last SLINE
4947 (line number) symbol we've seen, complaining and adopting the
4948 SLINE PC value if wrong.
4950 * symfile.h (struct complaint, complaint_root, complain,
4951 clear_complaints): Add.
4952 * symfile.c (complain, complaint_root, clear_complaints): Add
4953 facility to deal with non-fatal complaints and to regularize their
4955 (symbol_file_add): Clear complaint counters to allow new complaints.
4956 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4958 * dbxread.c (dbx_symfile_read): Remember the address and size
4959 of the string table for the main symbol file, so we won't read it
4961 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4962 to avoid reading the string table yet again. Lint.
4963 (throughout): Improve filtered output, including word wrap.
4964 (read_range_type): Improve Bothner's fix to handle other types too.
4966 * utils.c: Improve line wrap implementation. Handle unlimited
4967 width by making chars_per_line unsigned.
4968 (puts_filtered): New, easy, function.
4970 * defs.h (puts_filtered): add.
4972 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4973 call the identical sort_symtab_syms() in symfile.c instead.
4975 * expread.y: Suggest the `file' command rather than `symbol-file'.
4977 * command.h (enum var_types): Add zinteger for seroable
4979 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4980 nested if's into a switch.
4982 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4983 we did not stop because of a breakpoint (it must have been for
4984 some other reason, like a "stepi"), so don't print anything.
4986 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4987 doesn't include <sys/types.h>, old SunOS's require it for
4990 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4992 A test port of gdb-3.92.6 to the Sony NEWS.
4995 Don't normally link in remote- or vx stuff.
4996 Some of it doesn't compile, and it wastes space for 99% of the users.
4997 Remove reference to no-longer-used HAVE_VPRINTF.
4998 Fixed BFD_DEP typo to BFD_DIR.
5000 Fix cast in arg to bfd_h_getlong.
5001 Make char *prefix be const.
5002 Fix how certain range types are mapped into builtin unsigned int types.
5004 Remove 2 #includes. They cause errors (on Sony, at least),
5005 and aren't needed (they wern't in earlier versions).
5007 print_address_symbolic should never demangle labels
5008 (since it prints *assembler-level* labels).
5010 [This was superseded by the change to printcmd below.]
5013 Add some "volatile" return types to avoid warnings.
5014 If MISSING_VPRINTF add vprintf function and not just macro
5015 (since vprintf is used in printcmd.c).
5017 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
5018 (The latter isn't grokked by some PCC-based compilers.)
5020 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
5022 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
5023 * nindy-share/coffstrip.c
5024 Added some forward declarations (otherwise, gcc complains
5025 about implicit extern redefined as static).
5027 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
5029 Changes inspired by Per Bothner:
5030 * printcmd.c (print_address_symbolic): Take additional parameter
5031 specifying whether to demangle.
5032 (print_address): Pass in asm_demangle to control demangling.
5033 (print_address_demangle): New fn, takes explicit arg to control
5035 * utils.c: Add new vars demangle and asm_demangle, and let them
5037 (fputs_demangled): If !demangle, just print the argument.
5038 (fprint_symbol): If !demangle, just print raw symbol.
5039 * valprint.c (val_print): Call print_address_demangle rather than
5040 print_address, to cause demangling to depend on the global
5041 rather than assembler-level demangling setting.
5042 * WHATS.NEW, gdb.texinfo: Document.
5044 * main.c (show_command): Show all settings if no arg.
5045 (initialize_main): Make "info set" the same as naked "show".
5046 * command.c (cmd_show_list): Handle prefix commands in the
5047 list, and print the name of the setting as well as its English
5048 description and value.
5050 Allow gdb functions to specify where a line should wrap if it
5051 exceeds the size of a terminal line. Use it to make the output
5053 * utils.c (set_screen_width_command): New fn, mallocs a buffer
5054 of the right size when screen width changes.
5055 (set_screensize_command, screensize_info): Remove #if 0'd fns.
5056 (wrap_here): New fn, indicates a point in the output where we
5057 should wrap the line rather than just letting it overflow at a
5059 (fputs_filtered): Implement wrapping.
5060 (n_spaces): New fn, returns a pointer to N spaces.
5061 (print_spaces_filtered): Use n_spaces.
5062 * defs.h (n_spaces): Declare.
5063 * stack.c (print_frame_info): Wrap with 4-space indent after
5064 fn name and before filename and line number.
5065 * printcmd.c (print_frame_args): Wrap with 4-space indent
5066 before each argument name is printed.
5067 * valprint.c (value_print): Wrap with no indentation before
5069 (val_print_fields): Wrap with indentation relative to nesting
5070 level before each field name.
5071 (val_print): Wrap with nesting indentation before array elements.
5072 * command.c (do_setshow_command): Avoid extra newlines,
5073 wrap with 4-space indent around values printed, end with period.
5074 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
5076 * breakpoint.c (breakpoint_1): Implement addressprint for
5077 "info breakpoints" display. Change file name and line number
5078 format to " at file:nnn" rather than " (file line nnn)".
5079 * gdb.texinfo: Document.
5082 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
5084 Frozen for gdb-3.92.6 release.
5086 README, WHATS.NEW: Update for 3.92.6 release.
5088 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
5089 coffread.o from configs since it is now built by default.
5090 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
5091 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
5092 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
5093 from configs since it is now built by default.
5095 Makefile.dist: Update for release 3.92.6. Handle files that
5096 have been moved to ../include, ../getopt, or ../bfd. Add
5097 saber.suppress and tests directory. Add config.status to
5098 the release (it will say "none").
5100 coredep.c: Minor formatting fixes.
5102 These changes were made in early December but only checked in now:
5103 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
5104 nindy-share/nindy.c: lint
5105 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
5106 register values coming back from the target; we store values
5107 in target byte order everywhere.
5109 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
5111 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
5113 * valprint.c (cplus_val_print, val_print_fields): New functions,
5114 which print C++ objects. They conspire to avoid printing a
5115 virtual base class more than once, following all the twists and
5116 turns of C++ virtual base rules.
5117 (val_print): Call the above rather than do it by hand.
5119 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
5120 symbol file, not for added files like shared libs. This really
5121 needs to be generalized to a timestamp per file.
5123 * core.c (cleanup_core): Avoid coredump if no core file.
5125 * config.gdb: Accept -host or -target in place of +host or
5128 * coffread.c (find_linenos): Avoid desupported BFD interface
5129 to line numbers. We still read them manually rather than using
5130 BFD's "generic" features.
5132 * gdbrc.tex, threecol.tex: Add GDB reference card and its
5134 Makefile.dist: Add refcard to OTHERS list for creating tar files.
5136 * Makefile.dist: Eliminate use of $< in explicit targets.
5138 * readline/Makefile: Use $< rather than $*.c, which does not
5139 include the VPATH in GNU Make.
5141 * tconfig/i960-bout, tconfig/i960-coff: These are identical
5142 copies of tconfig/i960, added for global configuration
5143 compatability. All i960 versions can read both coff and b.out.
5145 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
5146 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
5149 * TODO: Think of more things to do.
5151 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
5153 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
5154 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
5155 64-bit float conversion.
5157 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
5158 equivalent to sun?os4 so global config works.
5160 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
5162 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
5164 * main.c: Only declare linesize once; declare pagesize not at
5165 all, since it is never used.
5166 (main): Clear newly allocated line before it is used.
5168 For older changes see ChangeLog-1990
