3 * configure.in, config/i386sol2.{mh,mt}: Preliminary Solaris-x86 conf.
5 Fri Sep 4 00:34:30 1992 Per Bothner (bothner@rtl.cygnus.com)
7 A bunch of changes mostly to improve debugging of C++ programs.
8 Specifically, the calling of inferiors methods is improved.
10 * value.h: New macros METHOD_PTR_IS_VIRTUAL,
11 METHOD_PTR_FROM_VOFFSET, METHOD_PTR_TO_VOFFSET to partially
12 hide the implementation details of pointer-to-method objects.
13 How to tell if the pointer points to a virtual method is
14 still very dependent on the particular compiler, but this
15 should make it easier to find the places to change.
16 * eval.c (evaluate_subexp [case OP_FUNCALL]), valprint.c
17 (val_print [case TYPE_CODE_PTR]): Use the new METHOD_PTR_*
18 macros, instead of a hard-wired-in code that incorrectly
19 assumed a no-longerused representation of pointer-to-method
20 values. And otherwise fix the relevant bit-rotted code.
22 * valprint.c (type_print_base [case TYPE_CODE_STRUCT]):
23 If there are both fields and methods, put a space between.
25 * stabsread.c (read_struct_type): Fix bug in handling of
26 GNU C++ anonymous type (indicated by CPLUS_MARKER followed
27 by '_'). (It used to prematurely exit the loop reading in
28 the fields, so it would think it should start reading
29 methods while still in the fields. This could crash gdb
30 given a gcc that can emit nested type information.)
32 * valops.c (search_struct_method): Pass 'this' value by
33 reference instead of by value. This provides a more
34 consistent interface through a recursive search where the
35 "bottom" functions may need to adjust offsets (due to multiple
37 * valops.c, value.h, values.c: Pass extra parameters to
38 value_fn_field and value_virtual_fn_field so we can
39 correctly adjust offset for multiple inheritance.
40 * eval.c (evaluate_subexp [case OP_FUNCALL]): Simplify
41 virtual function calls by using value_virtual_fn_field().
42 * values.c: New function baseclass_offset, derived from
43 baseclass_addr (which perhaps can be made obsolete?).
44 It returns an offset rather than an address. This is a
45 cleaner interface since it doesn't mess around allocating
47 * valops.c (search_struct_method): Use baseclass_offset
48 rather than baseclass_addr.
50 Mon Oct 5 16:02:04 1992 Stu Grossman (grossman at cygnus.com)
52 * Makefile.in: Re-install 29K/UDI stuff.
53 * remote-udi.c (udi_resume): Clean up.
54 * (udi_wait): Rewrite, leave out bugs.
55 * Add debugging code to print out all register fetches and stores.
56 * Straighten out target_ops.
57 * tm-29k.h (DUMMY_FRAME_RSIZE): Pad out to doubleword.
59 Mon Oct 5 09:46:44 1992 Ian Lance Taylor (ian@cygnus.com)
61 * remote-udi.c (udi_create_inferior): run with no arguments should
62 not pass the program name as an argument, since the UDI code
64 (udi_load): get the symbols from prog_name, not arg_string (the
65 load command should really use arg_string as the program name, not
66 prog_name, but at least the run command works now).
68 * munch: HP9000/300 nm puts an extra space between T and symbol
71 * config/irix4.mh: added -lsun to XM_CLIBS to get RPC functions
72 needed for vxworks targets.
74 Fri Oct 2 22:04:42 1992 John Gilmore (gnu@cygnus.com)
76 * am29k-tdep.c (_initialize_29k): Make it possible for the
77 user to set and query the address where function calls into the
78 inferior write a small scratch routine. `set call_scratch_address'

80 * remote.c (remote_prepare_to_store): Only fetch regs if they are
81 not already cached validly.

114 * dwarfread.c (read_ofile_symtab): Initialize dbsize and use it.
115 * dwarfread.c (basicdieinfo): Use dbsize to check for oversize
116 DIEs as well as the current check for undersize DIEs. This helps
117 to gracefully detect and reject corrupted DIE information.

400 * inferior.h (kill_inferior_fast): remove declaration.
402 * main.c (disconnect): call quit_cover using catch_errors rather

426 Replace with simple default to C before processing any init
427 files. There MUST be a language set, even in the absence of

512 (setup_arbitrary_frame): Implement FRAME_SPECIFICATION_DYADIC.
514 * mips-xdep.c (fetch_inferior_registers): ZERO_REGNUM always
515 comes back as zero. So does FP_REGNUM, as a trigger for
516 init_extra_frame_info.
518 * tm-mips.h (INIT_FRAME_PC_FIRST): Kludge, FIXME, defined to get
519 the program counter set before INIT_EXTRA_FRAME_INFO is run.

527 * copying.awk, copying.c (show_copying_command,
528 show_warranty_command): Rename from copying_info, warranty_info,
529 to match command function conventions.
531 * utils.c (prompt_for_continue): Reinitialize more-counts
532 before printing anything, and again afterward. Fix comments.

555 Preliminary cleanup for splitting host/native/target.
557 * infptrace.c (child_resume): Don't deal with NO_SINGLE_STEP
558 here; it is dealt with at a gdb-target-independent level.
559 * rs6000-tdep.c (single_step): Don't call ptrace, we are a
560 high toned routine. Fix return type to void.
561 * tm-rs6000.h (AIX_BUGGY_PTRACE_CALL): Zap, we think we fixed it.
562 Rich and I believe the "real problem" was that both single_step
563 and target_resume were issuing PT_CONTINUE calls. This would
564 cause the second PT_CONTINUE to sometimes fail because the process
566 * infptrace.c (child_resume): Remove AIX_BUGGY_PTRACE_CALL kludge.

575 (getpty (NCR)): Lotsa bug fixes...
576 (kernel_dispatch (case StopRType)): Use kill() instead of
577 killpg() so we can deal with losing systems...
578 (wait_for_events): Work around NCR select() lossage. It doesn't
579 zero out readfds when select() returns zero.
580 (energize_initialize): Use I_SETSIG to get SIGIO interrupts. Use
581 getcwd() instead of getwd() (NCR getwd() seg faults).
582 (energize_wait): Use sigaction() for NCR. Their version of signal()
583 is unreliable by default.
585 * procfs.c (proc_wait): Call print_sys_errmsg() if we get an
586 error from PIOCSWSTOP.
588 * breakpoint.c, core.c, exec.c, language.c, main.c, printcmd.c,

623 * tm-tahoe.h, xm-tahoe.h (KERNEL_U_ADDR): Move macro to xm-tahoe.h.
625 * stack.c (_initialize_stack): "dow" should be a valid abbreviation

630 * remote-vx.c: Rename realloc for inclusion of rpc/rpc.h, to avoid
631 redeclaration bug on SunOS 4.

694 * symtab.c (completion_list_add_symbol): restructured to optimize
695 for time. First clip names that cannot match. Then clip any
696 names we've already considered. Drop a redundant strncpy. Drop
697 a redundant malloc and associated free for demangled names.
699 Thu Sep 3 09:17:05 1992 Stu Grossman (grossman at cygnus.com)
701 * a68v-xdep.c (store_inferior_registers): Define as type void.
702 * configure.in: Add host m68k-apollo*-bsd*.

708 * utils.c (strcmp_iw): Add a hack to allow "FOO(ARGS)" to
709 match "FOO". This allows 'break Foo' to work when Foo is
710 a mangled C++ function. (See comment before function.)

740 * configure.in: Map unrecognized sun 68k's, sun sparcs, into
741 known suns in configure.in, rather than mapping them to unique
742 config files that happen to duplicate other config files.
743 * config/sun3.{mh,mt}: Remove (use identical sun3os4.*).
744 * config/sun4.{mh,mt}: Remove (use identical sun4os4.*).
746 Wed Sep 2 00:10:43 1992 John Gilmore (gnu@cygnus.com)
748 * configure.in (*-*-sunos*): Use trailing * to match all
749 sub-variants of SunOS, e.g. sunos4* to match sunos4.1.1.
750 (sparc-*-sunos3): Remove host & target. Sunos3 never shipped
751 in production on Sun-4.

761 target definitions for embedded with and without underlines on
762 identifiers. FIXME -- this ought to be known by BFD instead.
764 * tm-sparc.h, tm-sun2.h, tm-sun3.h: Delete NAMES_HAVE_UNDERSCORE:
765 not a parameter of the CPU, but of the development environment.
766 * tm-es1800.h, tm-sunos.h, tm-vx68.h: Add NAMES_HAVE_UNDERSCORE.
768 Tue Sep 1 17:31:45 1992 John Gilmore (gnu@cygnus.com)

795 * dwarfread.c (scan_partial_symbols): Call add_enum_psymbol here
796 for TAG_enumeration_types, rather than in add_partial_symbol.
797 * dwarfread.c (add_partial_symbol): Combine TAG_enumeration_type
798 case with class, struct, and union type cases, now that they are
799 the same. Remove tests for non-NULL name attributes, now done

812 (supply_gregset, fill_gregset, supply_fpregset, fill_fpregset):
813 Use "regi" for local indexing through register numbers, reserving
814 "regno" for the name of a specific register passed as an input
815 parameter. Fix bug propagated through all versions that sometimes
816 used regno as an index when it should have been regi, thus using
817 -1 as an index in some cases.

854 Use CORE_ADDRs. Change identifiers to lowercase.
856 * rs6000-xdep.c: Make whole file conditional on native RS/6000,
857 supplying dummy routines if non-native. Add prototype for
858 static exec_one_dummy_insn. Move a mess of functions to
859 rs6000-tdep.c (as above). Remove #if 0'd code.
861 * config/rs6000.mh (XDEPFILES): Move xcoffexec.o to target side.

895 * cplus-dem.c: Reorder args to most local functions to make them
896 follow the consistent pattern of struct work_stuff pointer first,
897 followed by pointer into string being demangled, followed by
898 pointer to the string where the result is being stored, followed
899 by other args. Also generally replace most variables of name
900 "type" with "mangled" for consistency. They all pointed to the
901 same string but half were one name and half the other.

918 numbers, signal number ranges, and to recognize "all" to mean all
919 signals except those used by the debugger.
920 * infrun.c (SET_SIGS, UNSET_SIGS): Macros used in handle_command
921 to set or reset actions for specific signals.

955 than dumping core by using the NULL pointer.
956 * symfile.c (symbol_file_command): Forget current_source_symtab
957 and current_source_line when discarding symbol table.

1389 * buildsym.c (cleanup_undefined_types): Don't rely on a
1390 flawed "Reasonable test to see if" a type has been defined
1391 since it was referred to; now we can just see if the
1392 TYPE_FLAG_STUB flag has been cleared.
1393 * valprint.c (print_type_base): Emit public/protected/private
1394 labels for methods as well as fields. Also, indent these labels
1395 2 spaces instead of 4, for a more conventional "look".
1396 * symtab.c (gdb_mangle_name): Undo Fred's change, unless
1397 GCC_MANGLE_BUG is defined. Also, handle destructors specially.
1398 * gcc.patch: New file. Contains patch for gcc (so people
1399 with gdb-2.2.x won't have to wait for a new gcc release).
1401 Thu Jul 9 18:44:26 1992 Ken Raeburn (raeburn@cygnus.com)
1403 * i960-pinsn.c (mem): Variables reg[123] should point to CONST.
1404 (print_addr): Call print_address to show symbolic version as well.
1406 * remote-vx.c (vx_kill): Don't look for arguments; they aren't
1408 (vx_read_register): Declare inferior_fp_regs. Delete code for
1409 copying "inferior_registers" around; the values are already in var
1410 "registers". Use correct size for register set.
1412 * remote-vx.c (vx_write_register): Don't try writing FP regs; the
1413 target doesn't support it.
1414 (vx_read_register): Don't try reading them either.
1416 * tm-i960.h (IP_REGNUM): Move to end of non-FP list, since the
1417 VxWorks back end reads them in one contiguous set except for this
1419 (register_names): Change "pc" to "pcw" to avoid confusion printing
1421 * tm-vx960.h (PC_REGNUM): Use RIP_REGNUM, since that's where we
1422 find the PC under VxWorks.
1424 Wed Jul 8 21:34:30 1992 Fred Fish (fnf@cygnus.com)
1426 * dwarfread.c (alloc_utype, decode_subscr_data): Call alloc_type

1444 breakpoint menus, instead of just file and line number.
1445 * symtab.c (name_match): Call cplus_demangle with DMGL_ANSI.
1446 * valprint.c (type_print_base): Print "class" for C++ classes,
1447 rather than "struct". Print section labels for public, protected
1448 and private members of C++ classes.
1449 * values.c: Include demangle.h.
1450 * values.c (value_headof): Call cplus_demangle with DMGL_ANSI.

1459 prevent crashes when examining cross-targets.
1460 * dbxread.c (process_one_symbol): Include directory name when
1461 calling start_subfile for SOL & BINCL symbols. This allows gdb to
1462 find include files, and yacc/lex sources when the cwd doesn't match
1463 that in which the object was compiled.
1464 * objfiles.h (ALL_MSYMBOLS): Don't seg fault when there are no
1466 * symtab.c (lookup_symtab_1): Rewrite. It now handles include

1502 that all cmd lists are owned by main.c.
1503 * language.c (setchecklist, showchecklist): Move to main.c, as
1504 implied by comment that all cmd lists are owned by main.c
1505 * breakpoint.c (enablelist, enablebreaklist, disablelist, cmdlist,
1506 deletelist): Remove redundant declarations (also in gdbcmd.h).
1507 * symmisc.c (printsyms_command): Now maintenance_print_symbols.

1532 tests energize.c. Configure energize, and build it automatically now.
1534 Sun Jul 5 09:43:28 1992 Fred Fish (fnf@cygnus.com)
1536 * Makefile.in (VERSION): Bump to 4.5.7.
1537 * cplus-dem.c (demangle_args): Validate index for previously
1538 seen type to guard against bogus values from malformed manglings.

1559 child processes, to avoid dead ones "hanging around" after GDB exits.
1560 (attach): Always stop the process if it needs it. Set RLC flag
1561 when attaching running processes, so it will continue if we detach
1562 it, quit, or are killed.
1563 (detach): Clear faults and set RLC flag to make process run
1565 (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR.
1567 (info_proc): Open process O_RDONLY, so we can see any process,
1568 even those controlled by debuggers.
1569 * tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG): They did (in Sol 2).
1571 Sat Jul 4 03:43:38 1992 John Gilmore (gnu at cygnus.com)
1573 Relocate symbols using an array of section_offsets, rather than a
1574 single `addr' or `offset'. This makes Solaris-2 support work, and
1575 permits better VxWorks (and maybe xcoff) support later.
1577 * symtab.h (struct section_offsets): New structure for keeping
1578 a set of offsets, rather than a single one.
1579 (struct objfile): Replace addr with section_offsets member.
1580 * symfile.h: Add sym_offsets to struct sym_fns. Conforming changes.
1581 * gdb-stabs.h: New include file with `symbol type specific'
1582 parameters for psymtabs and objfiles.

1589 offsets for this source file, based on the ELF symbol table info.
1590 (read_ofile_symtab): Yank N_CATCH, which is dead.
1591 (process_one_symbol, N_CATCH): Yank.
1592 (", N_FUN, N_FNAME, N_FN, N_FN_SEQ, N_SO, N_SOL, N_ENTRY):
1593 Relocate with SECT_OFF_TEXT.
1594 (", N_STSYM, N_LCSYM, N_ROSYM): Grope around in the stab string
1595 to distinguish relocatable from absolute symbols. Then, if not
1597 (", N_STSYM, N_DSLINE): SECT_OFF_DATA.
1598 (", N_LCSYM, N_BSLINE): SECT_OFF_BSS.
1599 (", N_ROSYM): SECT_OFF_RODATA.
1600 (elfstab_build_psymtabs): Caller has allocated dbx_symfile_info.
1601 (dbx_symfile_offsets): Add to translate addr to offset.
1602 * dwarfread.c: Conforming changes. Single offset currently used.
1603 * elfread.c: Add various complaints about elf/stab stuff.
1604 #include gdb-stabs.h. Conforming changes, using a single offset.
1605 (elf_symtab_read): Record info from BSF_FILE symbols, and local
1606 variables called "Bbss.bss", "Ddata.data", and "Drodata.rodata",
1607 for later use in building psymtabs.
1608 (elf_symfile_read): Allocate dbx_symfile_info here, to keep
1609 the info collected in elf_symtab_read. Cleanup calls free_elfinfo.
1610 (free_elfinfo): New fn, frees all chained stab_section_infos
1611 in an objfile, and zaps the start-of-chain pointer.
1612 (elfstab_offset_sections): New fn, looks in stab_section_info
1613 chain to determine section bases to relocate a psymtab's worth
1614 of symbols, as they are being read.
1615 * mipsread.c: Conforming changes. Stabs-reading will relocate
1616 using one offset. MIPS-reading will not relocate at all.
1617 * partial-stab.h: Relocate different symbol types using different
1618 offsets from section_offsets.
1619 * symfile.c: Conforming changes.
1620 (find_lowest_section): Unused function to use later
1621 to free us from the Tyranny of the Text Section.
1622 (syms_from_objfile): Translate absolute arg ADDR to offsets used
1623 in all lower layers of symbol reading. Call format-specific
1624 sym_offsets function to initialize offsets for high speed symbol
1626 (symbol_file_add): Call reinit_frame_cache so callers don't have to.
1627 (symbol_file_command, add_symbol_file_command): Callers changed.
1628 * symmisc.c (dump_psymtab): Print new relocation parameters.
1629 * xcoffread.c: Corresponding changes.
1631 * buildsym.c: Tidy innerblock_complaint and blockvector_complaint.
1632 * main.c (main): Read the $HOME/.gdbinit file before processing
1633 the argv arguments (e.g. reading symbol files or core
1634 files). This allows global parameters to be set, which will apply
1635 during the symbol reading. The ./.gdbinit is still read after
1637 * symtab.c (list_symbols): `i variables' shouldn't show enum values.
1638 * xcoffexec.c: Clean up quote inside comment.
1640 Fri Jul 3 20:18:26 1992 Fred Fish (fnf@cygnus.com)

1656 * dbxread.c (process_one_symbol): Ignore N_MAIN, N_ENDM for Solaris.
1657 * partial-stab.h: Ignore N_ENDM.
1658 * elfread.c (elf_symtab_read): Ignore symbols that don't have a
1659 CODE or DATA section attachment. This eliminates a lot of random
1660 values from shared libraries, which screw up the ordinary symbols
1661 in the address ranges they happen to overlap.
1662 * buildsym.c (define_symbol): Eliminate special tests
1663 for function types; move into "function" cases in switch statement.
1664 (define_symbol: 'f', 'F', 'P'): Process all parameter types
1665 in case they define new type numbers. But ignore them (FIXME).
1666 ('k', 'B'): Ignore const and volatile if we see them (FIXME).
1667 (read_sun_builtin_type): Add commentary.

1678 (fetch_core_registers): Use right parameters in dummy fn.
1680 Mon Jun 29 18:30:57 1992 John Gilmore (gnu at cygnus.com)
1682 * buildsym.c (scan_file_globals): Beware the null file.
1683 Fix from Jim Williams.

1689 * defs.h (memcpy, memset): Conditionalize decls on
1690 #ifndef MEM_FNS_DECLARED, since DECstation differs.
1691 (alloca): Break out the STDC and non-STDC alloca cases, to make
1692 it work on old preprocessors as well as "picky ANSI" ones.
1693 * xm-mips.h (memcpy, memset): Declare, and set MEM_FNS_DECLARED.
1695 * mips-tdep.c (heuristic_proc_start): Zero arg produces zero.
1696 * utils.c (fputs_demangled): Rename SLOP since DECstation system
1697 header files define it!
1699 * tm-29k.h (BREAKPOINT): Allow it to be overridden with -D.

1708 utils.c, valarith.c, valops.c, valprint.c, values.c:
1709 Replace bcopy() use with memcpy(), which is more standard and can
1710 take advantage of gcc's builtin functions for increased performance.

1722 * remote.c (remote_wait): Fix cast on signal() call.
1723 * defs.h (alloca): More diddling with alloca. Have to ensure
1724 that it has a prototype, so that if alloca is defined as a macro
1725 that takes an arg, the definition is seen as a use of a macro
1726 that takes an arg, to satisfy picky ANSI preprocessors.
1728 Sat Jun 27 12:12:20 1992 Fred Fish (fnf@cygnus.com)
1730 * sparc-pinsn.c: Use <string.h> rather than "string.h", for
1731 consistency with all other gdb files.

1754 from busted HP compiler.
1756 * partial-stab.h (N_SO): Rearrange code a little so that all SO
1757 stabs cause end_psymtab to be called.
1759 * buildsym.c (read_sun_builtin_type): Handle new FCS Sun CC
1760 compiler feature of putting 'c' into basic type descriptors for
1763 * procfs.c (child_resume): Work around Solaris (on Sparc) lossage
1764 where there is no place for nPC in prrun struct.

2473 Sun compiler output. FIXME, fix later.
2475 Remove unused header_file_prev_index mechanism. It was already

2495 variables. Instead, place all shared variables in a
2496 stack-allocated structure, and pass around its address.

3103 read_dbx_symtab): Remove the stringtab and stringtab_size params
3104 from the function prototypes, the function definition, and the
3105 function calls. These are now available via DBX_STRINGTAB and
3106 DBX_STRINGTAB_SIZE using the objfile pointer.

3126 * objfiles.c (allocate_objfile): Move calls to init_malloc()
3127 to prior to any calls to mmalloc for the objfile specific heap.
3128 * utils.c (init_malloc): Document the requirement that for each
3129 heap for which corruption checking is desired, that init_mmalloc
3130 must be called prior to any mmalloc calls on the heap.
3132 Thu Mar 26 13:20:06 1992 Per Bothner (bothner@cygnus.com)
3134 * rs6000-pinsn.c: Make dis-assembly output more like
3135 other targets: Don't print instruction in hex before
3136 the assembly; use print_address to print out jump
3139 Wed Mar 25 16:52:35 1992 Per Bothner (bothner@cygnus.com)
3141 * c-exp.y, gdbtypes.h: Add builtin_type_signed_char.

3148 Wed Mar 25 14:55:48 1992 Per Bothner (bothner@cygnus.com)
3150 * command.c, main.c (various places): Use ctype.h macros
3151 (such as isupper(x)), instead of hard-wiring in ASCII-isms
3152 (such as (x >= 'A' && x <= 'Z')).
3153 (There are still more of these in other files.)
3154 * main.c (defined_command): Lower-case the user's
3155 new command before entering it. Needed because
3156 command lookup is case-insensitive (and also lower-cases).
3157 (Based on Metin's earlier patch.)
3159 Tue Mar 24 23:27:01 1992 K. Richard Pixley (rich@cygnus.com)
3161 * config/irix4.mh: new file.

3186 continuation in yet another place (between method declarations).
3188 Mon Mar 23 23:01:41 1992 Stu Grossman (grossman at cygnus.com)
3190 * mips-tdep.c: include symfile.h and objfiles.h to fix
3193 Mon Mar 23 15:49:14 1992 Per Bothner (bothner@cygnus.com)
3195 * valops.c (value_struct_elt_for_reference): Added 'offset'

3263 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
3265 More C++ improvements (pointers to members, qualified names).
3266 * c-exp.y: Support exp.type::name and exp->type::name
3267 syntaxes. (Unfortunately, doesn't work for static members.)
3268 * c-exp.y, eval.c: Make type::~type work better.
3269 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
3270 value_static_field by value_struct_elt_for_reference.
3271 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
3272 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
3273 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
3274 for OP_SCOPE operand; no point in it now that we use lazy
3275 reading of values, and use "reference to member" objects.
3276 * gdbtypes.h: Clarify comment.
3277 * valops.c: Change value_struct_elt_for_address to return
3278 a reference (or variable), rather than a pointer. Change
3279 the name to value_struct_elt_for_reference to reflect this.
3280 Returning a reference instead of a address provides a
3281 generalization, since we can use the routine for both
3282 class::name as well as &class::name.
3283 Also, recurse to handle multiple inheritance properly.
3284 * valprint.c: Moved code to print pointer-to-members
3285 to new function point_class_member. This allows a
3286 "reference-to-member" to be printed using the same code.

3288 "struct " for domains of class-member types.
3289 * valops.c (search_struct_field): Inline code for simplified
3290 version of value_static_field (which can then be deleted).
3291 * value.h: Rename value_struct_elt_for_address to
3292 value_struct_elt_for_reference. Delete value_static_field.
3293 * values.c: Remove no longer used function value_static_field.

3298 elfread.c (coff_symfile_finish): Add function, prototype, and
3299 add to the xxxx_sym_fns struct for each file type. Also reformat
3300 the xxxx_sym_fns vector to a standard format and add comments.
3301 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
3302 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
3303 Pass pointer to struct objfile rather than pointer to sym_fns.
3304 Change references inside each function accordingly. Allocate any
3305 symbol file specific info in the per-objfile memory region.
3306 * dbxread.c (free_and_init_header_files): Break function into
3307 free_header_files(), called from dbx_symfile_finish(), and
3308 init_header_files(), called from dbx_new_init().
3309 * dbxread.c (dbx_new_init): Move deallocation things to new
3310 dbx_symfile_finish function.
3311 * elfread.c (elf_new_init): Call buildsym_new_init().
3312 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
3313 routine for the objfile before deallocating other stuff.
3314 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
3315 * symfile.h: Move struct sym_fns to before struct objfile def.
3316 Add sym_finish function pointer and change prototypes of other
3317 function pointers to reflect passing struct objfile pointer rather
3318 than struct sym_fns pointer.
3319 * symfile.c: Remove now obsolete symtab_fns pointer.
3320 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
3321 locates the correct sym_fns struct for the given objfile.
3322 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
3323 for better support of mapped symbol tables.
3324 * symfile.c (symbol_file_command): Remove obsolete code using
3326 * symfile.h: Remove duplicate declarations for symfile_objfile,
3327 entry_point, and object_files.
3328 * target.c (target_info): Compare symfile_objfile to NULL.
3329 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
3330 aixcoff_symfile_finish().

3342 * symtab.c: Other fixes to improve handing of operators.
3343 * valprint.c (type_print_base): Fix test for constructor.
3344 * values.c (value_static_field): Allow evaluation of
3345 CLASS::METHOD, returning a function pointer.
3347 Wed Mar 18 08:39:52 1992 Fred Fish (fnf@cygnus.com)
3349 * Makefile.in (VERSION): Roll 4.4.6.

3490 Merged in patches from metin@ibmpa.awdpa.ibm.com (Metin G.
3491 Ozisik) (dated Fri, 6 Mar 92 17:51) for the rs6000.
3492 * minsyms.c, symfile.c: Changes that may be generally
3493 applicable, but are #ifdef IBM6000 for now.
3494 * rs6000-xdep.c: Fixed typo in comment.
3495 * rs6000-tdep.c: Non-substatial changes.
3496 * xoffread.c: The main change here is addition of some

3508 * symtab.c (cplus_mangled_symbol): Add function.
3509 * symtab.c (lookup_symbol): Call cplus_mangled_symbol via
3510 iterate_over_msymbols to find demangled C++ symbol.
3511 * xcoffexec.c (relocate_minimal_symbol): Return meaningful
3512 value to iterate_over_msymbols().
3513 * xcoffexec.c (vmap_symtab): Ignore return from iterate_over_
3516 Fri Mar 6 21:59:34 1992 K. Richard Pixley (rich@cygnus.com)
3518 * Makefile.in: added check target.
3520 Thu Mar 5 23:56:01 1992 John Gilmore (gnu at cygnus.com)

3528 status, PC, and FP all in a single short message.
3529 (putpkt): Add further debugging of packet acks.
3530 * mipsread.c (fixup_symtab): Also swap RFD's.
3531 (parse_partial_symbols): Avoid bug on unknown symbol types.
3532 * Makefile.in (VERSION): Roll to 4.4.5.
3533 * mips-tdep.c (heuristic_proc_start): Avoid long delays
3534 for remote MIPS by limiting heuristic to 200 byte search.
3535 (heuristic_proc_desc): Byte-swapping.
3536 (mips_print_register): Cope with failure of
3537 read_relative_register_raw_bytes. Byte-swap integers for
3539 * mips-pinsn.c (print_insn): Byte-swap instruction.
3541 Thu Mar 5 12:32:09 1992 Stu Grossman (grossman at cygnus.com)
3543 * config.sub configure.in config/.Sanitize config/mh-irix4
3544 gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c
3545 gdb/procfs.c gdb/signame.h gdb/tm-irix3.h gdb/tm-mips.h
3546 gdb/xm-irix4.h gdb/config/.Sanitize gdb/config/mt-irix3
3547 gdb/config/mh-irix4 texinfo/configure.in: Port to SGI Irix-4.x.
3549 Wed Mar 4 11:56:42 1992 Fred Fish (fnf@cygnus.com)
3551 * defs.h, utils.c: xrealloc takes PTR as first arg.
3552 * defs.h: Reword confusing comment about ANSI prototypes.
3553 * defs.h: Some minor whitespace changes.
3554 * infrun.c (wait_for_inferior): Compare int tmp to int 0,
3555 not NULL, which can be (void *).
3556 * tm-amix.h, tm-i386v4.h: Add defines for setjmp/longjmp handling.
3557 * tm-i386v.h (SP_ARG0): Define
3558 * xm-sysv4.h: Back out of change for missing prototypes.
3559 * i386-tdep.c (get_longjmp_target): Add function.
3561 Wed Mar 4 05:46:11 1992 K. Richard Pixley (rich@rtl.cygnus.com)
3563 * Makefile.in: install man page too.
3565 Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
3567 * All GDB files that #include defs.h: Removed stdio.h.
3568 (defs.h): #include stdio.h.
3570 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
3572 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
3573 a ptype to reflect the setting of TARGET_PTR_BIT. Set the
3574 TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
3575 * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
3576 * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
3577 it before printing out the hex shape of an address.
3579 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
3581 * rs6000-xdep.c (frame_initial_stack_address): Move
3582 code to set frame->cache_fsr into new separate function
3583 frame_get_cacahe_fsr. This allows fixing a fatal error.
3584 * xcoffexec.c: Turn previously suppressed error
3585 message back on, after cleaning up BFD.
3587 * breakpoint.c (breakpoint_re_set): Removed (at least for now)
3588 printing of blank line, since it cases printing of an
3589 extra blank line. Is this intended? It does mess up
3591 * defs.h: Put back declarations of malloc and realloc,
3592 but protected by #ifndef MALLOC_INCOMPATIBLE.
3593 * objfiles.c: Undo previous change: Use malloc/realloc
3594 for objfile malloc/realloc fields (but add a cast).
3595 * xcoffexec.c: Suppress an error message (for now).
3597 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
3599 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
3600 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
3601 * buildsym.c: Use smash_to_pointer_type() to handle forward type
3603 * xcoffread.c: Modifications to C_DECL storage class handling, and
3604 introduction of an old smash_to_pointer_type() routine.
3606 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
3607 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
3608 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
3609 parameters have been modified.
3611 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
3612 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
3613 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
3614 and fetch_inferior_registers() always fetched all the registers
3615 resulting valid register values at hand all the time. Pushing a dummy
3616 frame did not require validating all register values first. After
3617 putting the above mechanism into action, we didn't have valid registers
3618 values always ready. Thus, all registers need to be fetched before
3619 pushing a dummy frame now.
3621 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
3622 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
3623 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
3624 the starting address (actual frame address) of a frame.
3625 * rs6000-tdep.c: modifications to function_frame_info() to see if
3626 function reserves a frame pointer register (alloca register)
3627 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
3628 FRAME_LOCALS_ADDRESS has been updated to support debugging of
3629 functions with alloca() calls.
3631 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
3633 * xm-sysv4.h: Provide definitions/prototypes for host environment
3634 functions for which no definitions or prototypes are provided in
3635 any currently included gdb or host environment header files.
3636 For SVR4, this currently includes malloc and realloc, which cannot
3637 be portably prototyped in any gdb include file.
3639 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
3641 * buildsym.h: Remove obsolete variable file_stabs.
3643 * Makefile.in: Move place where configure merges in host-
3644 and target-dependent fragments later, so the latter
3645 can override (say) GNU_MALLOC.
3646 * config/mh-rs6000: Use system malloc. Otherwise, I
3647 ended up with *two* incompatible versions of malloc
3648 (functions in libc would call the malloc in libc).
3649 I assume this is a shared library problem.
3651 * remote.c: Fix (presumed) typo.
3652 * objfiles.c: Use xmalloc/xrealloc instead of
3653 malloc/realloc (since the latter are no longer declared).
3655 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
3656 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
3657 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
3658 handle individual registers.
3659 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
3660 correctly in case it wasn't cached yet. (A problem showed up
3661 after fetching individual registers.)
3662 * buildsym.c: Disable type_synonym_name's type name overwriting
3663 in cases it is unnecesary. rs6000 portation doesn't use
3664 type_synonym_name, and it used to nullify type names
3665 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
3666 type's name as soon as space for that type is allocated.
3667 * xcoffread.c: ignore a section's lineno information if it is
3668 not `.text'. (In rs6000 bfd portation integration, skipping over
3669 `.pad' sections are ignored since it was in machine independent
3670 part of the code. Thus, a problem of fake sections with invalid
3671 lineno information arised.)
3673 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
3674 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
3675 * rs6000-tdep.c: make function_frame_info() work whether or not
3676 reading from a core file.
3677 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
3679 * infrun.c. main.c, printcmd.c. symtab.c:
3680 More changes from IBM for rs6000.
3683 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
3685 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
3686 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
3687 Merge in changes (mostly from IBM) for RS6000.
3688 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
3689 More changes from IBM for RS6000. These are in machine-
3690 independent code, and probably could do with some cleaning
3691 up. The most questionable of these are #ifdef IBM6000.
3692 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
3693 to single_step() (for consistency with rs6000 and i860).
3694 * utils.c: Allow the 1st arg to xrealloc to be NULL
3695 (in which case do malloc). This removes the need for
3696 some tests in xcoff code (and perhaps other places?).
3697 * coffread.c: Removed variables last_source_file,
3698 type_vector, and type_vector_length as these are now
3699 defined by buildsym.[ch].
3700 * defs.h: Remove prototypes for malloc and realloc, since
3701 these should only be used to implement xmalloc and xrealloc,
3702 and they conflict with <stdlib.h> in AIX - where they
3703 return void* even when __STDC__ isn't defined. Sigh.
3704 * munch: Recognize *initialize* in data as well as text
3705 (AIX uses data). Also, incorporate a patch from Garrett
3706 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
3707 much more sensible, by only trying to match the name of
3708 the initialize_foo function, and not the junk before it.
3710 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
3712 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
3713 unless symbol table indicates that something has changed.
3715 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
3717 * remote.c: Make it work for embedded MIPS. Increase buffer
3718 size, and use throughout. Round buffer size up if too many regs.
3719 Support baud rate setting and try for an 8-bit path. If
3720 interrupted while waiting for target, send a ^C down the wire.
3721 Avoid single-byte reads.
3722 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
3724 * mips-xdep.h: Avoid the embedded regs when on Unix.
3726 * mipsread.c: Byte-swap the symbol table structures, using
3727 routines from ecoff.c, to read a symbol table written in any
3728 of the four possible byte orders.
3729 * configure.in (mips-big-* target): Same as Sony News.
3730 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.
3731 * ecoff.c: New file for symbol swapping routines.
3733 Thu Feb 27 09:26:38 1992 Stu Grossman (grossman at cygnus.com)
3735 * breakpoint.c (all_breakpoints_info, breakpoint_1): Add 'info
3736 all-breakpoints' command.
3737 * (get_number): Allow users to enter negative breakpoint numbers.
3738 * (breakpoint_1): Reformat display of 'info break' to show new
3740 * (create_longjmp_breakpoint, breakpoint_re_set,
3741 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
3742 symfile.c (syms_from_objfile): Re-do
3743 insertion of longjmp breakpoints. Move all code into
3744 breakpoint_re_set, and call that instead of
3745 create_longjmp_breakpoint in symfile.c.
3747 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
3749 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.
3750 * breakpoint.c (breakpoint_re_set): Use ALL_BREAKPOINTS_SAFE.
3751 * symtab.c (find_pc_symtab): Handle having no objfiles.
3752 * infcmd.c: Fix comment.
3753 * objfiles.c (free_all_objfiles): Add.
3754 * symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE): Add.
3755 * symfile.c (symbol_file_command): free all objfiles when
3756 specifying a new symbol file.
3757 (reread_symbols): Stat the file name, don't fstat the descriptor.
3759 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
3761 * Makefile.in, configure.in: removed traces of namesubdir,
3762 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
3763 copyrights to '92, changed some from Cygnus to FSF.
3765 Tue Feb 25 19:31:19 1992 Stu Grossman (grossman at cygnus.com)
3767 * dbxread.c (end_psymtab): Delete empty psymtabs.
3768 * symfile.c (allocate_psymtab): Recycle empty psymtabs.
3769 * symfile.h (struct objfile): Add free_psymtabs.
3771 Sat Feb 22 02:00:32 1992 John Gilmore (gnu at cygnus.com)
3773 * Makefile.in (VERSION): Roll to gdb-4.4.4.
3775 * symfile.c (symbol_file_command): strcmp => !strcmp.
3776 * breakpoint.h: Move prototypes to follow enum definition they need.
3777 * breakpoint.c, infrun.c: Lint.
3778 * printcmd.c: Use `enum enable' rather than `enum
3780 * mipsread.c: First pass at making it compile with the new
3781 objfile changes. Probably seriously broken still, but it
3784 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

3788 mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
3789 stepping (and nexting) through longjmp(). Also, cleanup
3790 breakpoint handling quite a bit by creating explicit breakpoint
3791 types instead of using magic breakpoint numbers.
3792 Makefile.in: Update version to 4.4.3
3794 Sat Feb 22 00:08:50 1992 John Gilmore (gnu at cygnus.com)
3796 * buildsym.c, dwarfread.c, gdbtypes.c, inflow.c, main.c,
3797 minsyms.c, printcmd.c, remote.c, saber.suppress: Saberlint.
3798 * symmisc.c, xcoffread.c: Move debug functions to symmisc.c.
3800 * xm-sun3os4.h, xm-sun4os4.h: Enable HAVE_MMAP.
3802 * minsyms.c (install_minimal_symbols): Add bunches to any
3803 existing minsyms in the objfile. Avoid extra mallocation
3804 by working directly in the obstack. Remove ignored `mainline' parm.
3805 * coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
3806 xcoffread.c: Change all callers.
3807 * FIXME: We should be able to eliminate MAINLINE from all the
3808 symbol readers now, with a small bit of work.
3810 * valops.c, value.h: Lint.
3811 * remote-vx.c: Add missing break; statement. Bugfix by
3812 Michael Sclafani, <sclafani@src.dec.com>.

4251 * mipsread.c (parse_partial_symbols): Handle dependencies
4252 between partial symbol tables (when not doing stabs-in-ecoff).
4253 (This used to be handled by parse_fdr, but parse_fdr was
4254 incompatible with handling stabs-in-ecoff, so the code
4255 was re-written to not use parse_fdr. Unfortunately,
4256 the logic to handle dependencies was overlooked.)

4276 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
4278 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
4279 (This is just for clarity - and one day permitting us to
4280 change FP0_REGNUM from 38 to 32, which would make more sense.)
4281 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
4282 register numbers in stabs-in-ecoff get handled correctly.

4301 * mipsread.c: Prepend "struct " to the names of structure
4302 types, and similarly for enums and unions. (This used
4303 to be done, but got lost in the re-write to "guess" the
4304 difference between enum/struct/union.)
4305 Also, guess that a tag is an enum if the first member
4308 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
4310 * xm-vax.h: #ifndef ultrix around #include of endian.h and
4313 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
4315 * Projects: Patching executables is done.
4316 * Makefile.in (VERSION): Roll to gdb-4.4.
4317 * README, WHATS.NEW: Update for gdb-4.4.
4319 * symfile.c (reread_symbols): Whenever we reread one object
4320 file's symbols, we must restart the scan, because the object_files
4321 chain has been permuted.
4323 * exec.c (exec_files_info): Split out into print_section_info.
4324 Print BFD filename of each section if it's not the default one.
4325 * core.c (core_files_info): Call print_section_info.
4327 * xm-vax.h: Include a few system header files whose definitions
4328 must precede defs.h.
4329 * language.c, language.h: Make some things const.
4330 * expression.h, main.c: const spreads like ooze.
4332 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
4333 since BREAKPOINT values can be >0x80.
4335 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
4337 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
4339 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
4341 * sparc-pinsn.c: Remove kludge for preferring architectures.
4342 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
4343 and forever. Add `add' instruction to the set that get checked
4344 for a preceding `sethi' in order to print an absolute address.
4345 Corresponding changes in ../include/opcode/sparc.h needed
4346 to eliminate garbage instructions.
4348 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
4350 * mipsread.c (parse_partial_symbols): Make sure partial
4351 symbols are created for external symbols (as used to be
4352 the case). This is a bit of a pain with the mips-coff.
4353 It uses a table which points to all of the external
4354 symbols belonging to a particular FDR or psymtab.
4355 Once we've generated this table, we might as well save
4356 it, and then use it in psymtab_to_symtab_1 to find
4357 the symbols to pass to parse_external().
4358 * symfile.c, symfile.c: New function start_psymtab_common
4359 to share the common parts of allocating a new psymtab
4360 for dbxread, mipsread (and later dwarfread). Its code
4361 was pulled out from start_psymtab in dbxread.c.
4362 * dbxread.c (start_psymtab): Use start_psymtab_common().
4364 * valprint.c (val_print): If there is an error when trying
4365 to print a string, check to see if there really is a problem
4366 by reading just one character. If that works, assume
4369 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
4371 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
4372 cypress, v8 mnemonics in that order.
4374 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
4376 * sparc-pinsn.c: Put the qsort() back in.
4378 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
4380 * findvar.c (read_register, write_register): Handle machines
4381 where REGISTER_TYPE is not the same size as "int".
4383 Handle debug symbols in dynamically loaded (relocated) code:
4385 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
4386 offset to process_one_symbol.
4387 (process_one_symbol): Take new offset parameter. Add it into
4388 appropriate symbol types to relocate symbols to loaded addresses.
4389 Handle all possible symbol types, and complain() about types that
4390 we don't expect to see.
4391 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
4392 process_one_symbol (FIXME, should pass real offset).
4396 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
4398 (set_breakpoint, break_command_1, until_break_command,
4399 catch_command_1, breakpoint_re_set_one): Use it.
4400 * symtab.h (resolve_sal_pc): Declare.
4401 * infcmd.c (jump_command): Use resolve_sal_pc.
4403 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
4405 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
4407 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
4409 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4410 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
4411 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
4413 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
4415 * dbxread.c (process_one_symbol): Make a first cut at handling
4416 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
4418 * symtab.c (find_pc_line): Fix stepping into and out of #included
4421 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
4423 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
4424 no longer any need to copy ../include/opcode/* into gdb.
4426 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
4428 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
4430 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
4432 * valprint.c (type_print_base, type_print_method_args):
4433 Print C++ constructor methods without bogus "return type."
4435 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
4437 * infptrace.c (child_xfer_memory): Parameter "target" should
4438 be a pointer to a structure, not the entire structure.
4440 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
4442 * depend: Convert the couple of references to ansidecl.h that
4443 used the local gdb version to use the ../include version.
4445 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
4448 (child_xfer_memory): Takes pointer to a struct, not entire struct.
4449 (inferior_proc_init): Fix non-ANSI version of args.
4450 (attach): Call print_sys_errmsg with correct number of args.
4451 (mappingflags): Make static, does not need to be global.
4453 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
4454 not the entire struct itself.
4456 * valops.c (value_assign): Cast some args to modify_field() and
4457 {read,write}_register_bytes() correctly.
4459 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
4461 * Makefile.in (MALLOCSRC): Removed reference to removed local
4464 * dwarfread.c (list_in_scope): Needs an initial value, use file
4467 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
4469 * main.c (main): Make option_index local to keep new getopt happy.
4470 main.c, solib.c, Makefile.in: Update copyright notices.
4472 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
4474 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
4476 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
4478 * Makefile.in (HFILES): Add partial-stab.h.
4480 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
4482 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
4483 New files for stratus. Not complete enough to actually build
4484 on the Stratus machine; that awaits copyright assignment for
4487 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
4488 for getting custom flags into CFLAGS when doing makes.
4490 * configure.in: Add config information for stratus.
4492 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
4494 * dbxread.c (process_one_symbol): Pass address of structure
4495 to complain(), rather than the whole structure.
4497 Wed Jan 15 09:56:16 1992 Fred Fish (fnf at cygnus.com)
4499 * solib.c (solib_add_common_symbols): Only compile in when not
4500 using SVR4 style shared libraries.
4502 Tue Jan 14 22:34:00 1992 Fred Fish (fnf at cygnus.com)
4504 * dwarfread.c (locval): Add offreg flag to indicate location
4505 values that are computed off a base register.
4507 * dwarfread.c (new_symbol): Rework TAG_global_variable and
4508 TAG_local_variable cases to account for static variables
4509 within function scopes.
4511 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
4513 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
4514 doesn't exist on some systems.
4516 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
4517 nexting over recursive function calls.
4519 * target.c (target_read_string): Create this routine to read null
4520 terminated strings from the target. It deals with running off the
4521 end of memory elegantly as well. solib.c (find_solib): Use
4522 target_read_string() to avoid problems with running off the end of
4525 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
4526 that reference pgrp_inferior.
4528 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
4530 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
4531 mips-tfile has been hacked to act more "traditionally."
4532 * dbxread.c: Fixed typo in comment.
4534 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
4536 * mips-tdep.c (mips_skip_prologue): Add some number of
4537 'sw' instructions before 'addiu' adjusts the stack.
4539 Fri Jan 10 13:47:06 1992 Fred Fish (fnf at cygnus.com)
4541 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
4542 freescope, buildblock closescope, record_line, add_symbol_to_list,
4543 gatherblocks, make_blockvector): Extensive changes to switch
4544 to generic symbol table building code in buildsym.c. Remove
4545 scope tree structures and functions, symbol table building
4546 functions, and lots of other small changes.
4548 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
4549 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
4551 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)
4553 * buildsym.c (cleanup_undefined_types): Add support for enums.

4564 in ../include/opcode/sparc.h.
4566 Wed Jan 1 04:29:00 1992 Fred Fish (fnf at cygnus.com)
4568 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
4569 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
4570 to reflect actual locations of opcode files, so TAGS target will
4573 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
4575 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
4578 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
4579 dereferencing to access the correct elements.
4581 * valops.c (value_addr): Declare return type of external func
4584 * xcoffread.c: Undefine next_symbol_text before redefining it.
