15 start of function args, forget all remembered types for
16 lucid/cfront style demangling.
17 * cplus-dem.c (demangle_prefix): In a sequence of two or more
18 underbar characters, use last pair as the delimiter. Hoist

53 * mem-break.c: Restore test of BREAKPOINT size that Fred removed.
54 As the man page says, "Sometimes you just can't get lint to shut

58 it up over the next few weeks. Make mips x 29k build.
59 * tm-29k.h (CALL_DUMMY): Make it work on cross-endian hosts.
60 (FIX_CALL_DUMMY): Comment in the patching of the breakpoint,
61 but leave it as a comment because the breakpoint instruction
62 is not easily accessible at this moment (it's static, and if
63 we define one here, it goes into every file compiled).

245 lookup_demangled_partial_symbol,): Ask demangle_and_match to

250 to start_symtab as the directory name.
251 * dwarfread.c (completedieinfo): Strip off any leading hostname

349 * gdbtypes.c, gdbtypes.h: New function lookup_signed_typename.
350 * c-exp.y: Call lookup_signed_typename() after seeing
351 "signed". This handles "signed char" correctly.
352 * c-exp.y: Recognize (but ignore) 'const' and 'volatile'
353 keywords before a type specifier.

371 Thu Jul 9 19:05:27 1992 Per Bothner (bothner@rtl.cygnus.com)
373 * gdbtypes.c (lookup_struct_elt_type): If the input type is
374 TYPE_CODE_PTR or TYPE_CODE_REF, dereference it to get the
375 target type. Otherwise, 'whatis this.field' wouldn't work,
376 which would be inconsistent, since 'print this.field' works.
377 * buildsym.c (read_struct_type, read_enum_type): Clear
379 * buildsym.c (cleanup_undefined_types): Don't rely on a
380 flawed "Reasonable test to see if" a type has been defined

382 TYPE_FLAG_STUB flag has been cleared.
383 * valprint.c (print_type_base): Emit public/protected/private
384 labels for methods as well as fields. Also, indent these labels
385 2 spaces instead of 4, for a more conventional "look".

393 * i960-pinsn.c (mem): Variables reg[123] should point to CONST.
394 (print_addr): Call print_address to show symbolic version as well.
396 * remote-vx.c (vx_kill): Don't look for arguments; they aren't
398 (vx_read_register): Declare inferior_fp_regs. Delete code for
399 copying "inferior_registers" around; the values are already in var
400 "registers". Use correct size for register set.
402 * remote-vx.c (vx_write_register): Don't try writing FP regs; the
403 target doesn't support it.
404 (vx_read_register): Don't try reading them either.
406 * tm-i960.h (IP_REGNUM): Move to end of non-FP list, since the
407 VxWorks back end reads them in one contiguous set except for this
409 (register_names): Change "pc" to "pcw" to avoid confusion printing
411 * tm-vx960.h (PC_REGNUM): Use RIP_REGNUM, since that's where we
412 find the PC under VxWorks.

416 * dwarfread.c (alloc_utype, decode_subscr_data): Call alloc_type

423 * gdbtypes.h (struct cplus_struct_type): Add comments describing
424 use of various fields.
425 * gdbtypes.c (print_bit_vector, print_cplus_stuff): New functions.
426 * c-exp.y (%token): Add CLASS as a token for C++, add grammar
427 production that currently treats it exactly the same as STRUCT.
428 * c-exp.y (yylex): Recognize "class" as token CLASS.
429 * symtab.c (gdb_mangle_name): Rewrite to match current g++ stabs.
430 * symtab.c (decode_line_1): Fix to pass quoted args on down to
431 general symbol handling code. Call cplus_mangle_opname with
433 * symtab.c (decode_line_2): Print demangled function names in
434 breakpoint menus, instead of just file and line number.
435 * symtab.c (name_match): Call cplus_demangle with DMGL_ANSI.
436 * valprint.c (type_print_base): Print "class" for C++ classes,
437 rather than "struct". Print section labels for public, protected
438 and private members of C++ classes.
439 * values.c: Include demangle.h.

446 Wed Jul 8 00:11:02 1992 Stu Grossman (grossman at cygnus.com)
448 * dbxread.c (dbx_symfile_init): Init stab_section_info to NULL to
449 prevent crashes when examining cross-targets.
450 * dbxread.c (process_one_symbol): Include directory name when
451 calling start_subfile for SOL & BINCL symbols. This allows gdb to
452 find include files, and yacc/lex sources when the cwd doesn't match
453 that in which the object was compiled.
454 * objfiles.h (ALL_MSYMBOLS): Don't seg fault when there are no
456 * symtab.c (lookup_symtab_1): Rewrite. It now handles include
459 Tue Jul 7 09:00:42 1992 Fred Fish (fnf@cygnus.com)
461 * maint.c (maintenance_command, maintenance_info_command):

549 child processes, to avoid dead ones "hanging around" after GDB exits.
550 (attach): Always stop the process if it needs it. Set RLC flag
551 when attaching running processes, so it will continue if we detach
552 it, quit, or are killed.
553 (detach): Clear faults and set RLC flag to make process run
555 (open_proc_file): New `mode' argument for O_RDONLY or O_RDWR.

561 Sat Jul 4 03:43:38 1992 John Gilmore (gnu at cygnus.com)
563 Relocate symbols using an array of section_offsets, rather than a
564 single `addr' or `offset'. This makes Solaris-2 support work, and
565 permits better VxWorks (and maybe xcoff) support later.
567 * symtab.h (struct section_offsets): New structure for keeping
568 a set of offsets, rather than a single one.
569 (struct objfile): Replace addr with section_offsets member.

578 (start_psymtab): Call elfstab_offset_sections to calculate good
579 offsets for this source file, based on the ELF symbol table info.
580 (read_ofile_symtab): Yank N_CATCH, which is dead.
581 (process_one_symbol, N_CATCH): Yank.
582 (", N_FUN, N_FNAME, N_FN, N_FN_SEQ, N_SO, N_SOL, N_ENTRY):
583 Relocate with SECT_OFF_TEXT.
584 (", N_STSYM, N_LCSYM, N_ROSYM): Grope around in the stab string
585 to distinguish relocatable from absolute symbols. Then, if not
587 (", N_STSYM, N_DSLINE): SECT_OFF_DATA.
588 (", N_LCSYM, N_BSLINE): SECT_OFF_BSS.
589 (", N_ROSYM): SECT_OFF_RODATA.
590 (elfstab_build_psymtabs): Caller has allocated dbx_symfile_info.

596 variables called "Bbss.bss", "Ddata.data", and "Drodata.rodata",
597 for later use in building psymtabs.
598 (elf_symfile_read): Allocate dbx_symfile_info here, to keep
599 the info collected in elf_symtab_read. Cleanup calls free_elfinfo.
600 (free_elfinfo): New fn, frees all chained stab_section_infos
601 in an objfile, and zaps the start-of-chain pointer.
602 (elfstab_offset_sections): New fn, looks in stab_section_info
603 chain to determine section bases to relocate a psymtab's worth
604 of symbols, as they are being read.
605 * mipsread.c: Conforming changes. Stabs-reading will relocate
606 using one offset. MIPS-reading will not relocate at all.
607 * partial-stab.h: Relocate different symbol types using different
608 offsets from section_offsets.
609 * symfile.c: Conforming changes.
610 (find_lowest_section): Unused function to use later
611 to free us from the Tyranny of the Text Section.
612 (syms_from_objfile): Translate absolute arg ADDR to offsets used
613 in all lower layers of symbol reading. Call format-specific
614 sym_offsets function to initialize offsets for high speed symbol
616 (symbol_file_add): Call reinit_frame_cache so callers don't have to.
617 (symbol_file_command, add_symbol_file_command): Callers changed.

622 * main.c (main): Read the $HOME/.gdbinit file before processing
623 the argv arguments (e.g. reading symbol files or core
624 files). This allows global parameters to be set, which will apply
625 during the symbol reading. The ./.gdbinit is still read after
627 * symtab.c (list_symbols): `i variables' shouldn't show enum values.
628 * xcoffexec.c: Clean up quote inside comment.

647 * partial-stab.h: Ignore N_ENDM.
648 * elfread.c (elf_symtab_read): Ignore symbols that don't have a
649 CODE or DATA section attachment. This eliminates a lot of random
650 values from shared libraries, which screw up the ordinary symbols
651 in the address ranges they happen to overlap.
652 * buildsym.c (define_symbol): Eliminate special tests
653 for function types; move into "function" cases in switch statement.
654 (define_symbol: 'f', 'F', 'P'): Process all parameter types
655 in case they define new type numbers. But ignore them (FIXME).
656 ('k', 'B'): Ignore const and volatile if we see them (FIXME).

670 Mon Jun 29 18:30:57 1992 John Gilmore (gnu at cygnus.com)
672 * buildsym.c (scan_file_globals): Beware the null file.
673 Fix from Jim Williams.

680 #ifndef MEM_FNS_DECLARED, since DECstation differs.
681 (alloca): Break out the STDC and non-STDC alloca cases, to make
682 it work on old preprocessors as well as "picky ANSI" ones.
683 * xm-mips.h (memcpy, memset): Declare, and set MEM_FNS_DECLARED.
685 * mips-tdep.c (heuristic_proc_start): Zero arg produces zero.

712 * remote.c (remote_wait): Fix cast on signal() call.
713 * defs.h (alloca): More diddling with alloca. Have to ensure
714 that it has a prototype, so that if alloca is defined as a macro
715 that takes an arg, the definition is seen as a use of a macro
716 that takes an arg, to satisfy picky ANSI preprocessors.
718 Sat Jun 27 12:12:20 1992 Fred Fish (fnf@cygnus.com)
720 * sparc-pinsn.c: Use <string.h> rather than "string.h", for

911 C++ syms as demangled, not just functions.
912 * buildsym.c (read_range_type): When we find a signed char

973 for static data members.
974 * dbxread.c (dbx_psymtab_to_symtab_1): Fix prototype.

1279 allowing hosts with different text and binary file formats to
1281 * coffread.c (read_coff_symtab): changed calling convention and

2143 (There are still more of these in other files.)
2144 * main.c (defined_command): Lower-case the user's
2145 new command before entering it. Needed because
2146 command lookup is case-insensitive (and also lower-cases).

2210 * blockframe.c, buildsym.h, coffread.c, dwarfread.c, mipsread.c,
2211 symfile.c, mips-tdep.c (startup_file_start, startup_file_end):
2212 Remove extern decls.
2213 * symfile.c, symfile.h (entry_point): Remove extern decl.

2235 works for the majority of targets.
2236 * tm-68k.h, tm-convex.h, tm-h8300.h, tm-i386v.h, tm-irix3.h,
2237 tm-merlin.h, tm-mips.h, tm-pyr.h, tm-rs6000.h, tm-sparc.h,
2238 tm-sun386.h, tm-tahoe.h, tm-umax.h, tm-vax.h (FRAME_CHAIN_VALID):

2243 * partial-stab.h: Use new per-objfile entry info.
2244 * symfile.h (struct objfile): Removed, moved to objfiles.h.

2253 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
2255 More C++ improvements (pointers to members, qualified names).
2256 * c-exp.y: Support exp.type::name and exp->type::name
2257 syntaxes. (Unfortunately, doesn't work for static members.)
2258 * c-exp.y, eval.c: Make type::~type work better.
2259 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
2260 value_static_field by value_struct_elt_for_reference.
2261 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
2262 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
2263 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
2264 for OP_SCOPE operand; no point in it now that we use lazy
2265 reading of values, and use "reference to member" objects.
2266 * gdbtypes.h: Clarify comment.
2267 * valops.c: Change value_struct_elt_for_address to return
2268 a reference (or variable), rather than a pointer. Change
2269 the name to value_struct_elt_for_reference to reflect this.
2270 Returning a reference instead of a address provides a
2271 generalization, since we can use the routine for both
2272 class::name as well as &class::name.
2273 Also, recurse to handle multiple inheritance properly.
2274 * valprint.c: Moved code to print pointer-to-members
2275 to new function point_class_member. This allows a
2276 "reference-to-member" to be printed using the same code.
2277 * valprint.c (type_print_varspec_prefix): Avoid printing
2278 "struct " for domains of class-member types.
2279 * valops.c (search_struct_field): Inline code for simplified
2280 version of value_static_field (which can then be deleted).
2281 * value.h: Rename value_struct_elt_for_address to
2282 value_struct_elt_for_reference. Delete value_static_field.
2283 * values.c: Remove no longer used function value_static_field.

2290 the xxxx_sym_fns vector to a standard format and add comments.
2291 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,
2292 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
2293 Pass pointer to struct objfile rather than pointer to sym_fns.
2294 Change references inside each function accordingly. Allocate any
2295 symbol file specific info in the per-objfile memory region.
2296 * dbxread.c (free_and_init_header_files): Break function into
2297 free_header_files(), called from dbx_symfile_finish(), and
2298 init_header_files(), called from dbx_new_init().
2299 * dbxread.c (dbx_new_init): Move deallocation things to new
2300 dbx_symfile_finish function.
2301 * elfread.c (elf_new_init): Call buildsym_new_init().
2302 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
2303 routine for the objfile before deallocating other stuff.
2304 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
2305 * symfile.h: Move struct sym_fns to before struct objfile def.
2306 Add sym_finish function pointer and change prototypes of other
2307 function pointers to reflect passing struct objfile pointer rather
2308 than struct sym_fns pointer.
2309 * symfile.c: Remove now obsolete symtab_fns pointer.
2310 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
2311 locates the correct sym_fns struct for the given objfile.
2312 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
2313 for better support of mapped symbol tables.
2314 * symfile.c (symbol_file_command): Remove obsolete code using
2316 * symfile.h: Remove duplicate declarations for symfile_objfile,
2317 entry_point, and object_files.
2318 * target.c (target_info): Compare symfile_objfile to NULL.
2319 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
2320 aixcoff_symfile_finish().

2332 * symtab.c: Other fixes to improve handing of operators.
2333 * valprint.c (type_print_base): Fix test for constructor.
2334 * values.c (value_static_field): Allow evaluation of
2335 CLASS::METHOD, returning a function pointer.
2337 Wed Mar 18 08:39:52 1992 Fred Fish (fnf@cygnus.com)
2339 * Makefile.in (VERSION): Roll 4.4.6.

2575 message back on, after cleaning up BFD.
2577 * breakpoint.c (breakpoint_re_set): Removed (at least for now)

2601 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
2602 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
2603 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
2604 and fetch_inferior_registers() always fetched all the registers
2605 resulting valid register values at hand all the time. Pushing a dummy
2606 frame did not require validating all register values first. After
2607 putting the above mechanism into action, we didn't have valid registers
2608 values always ready. Thus, all registers need to be fetched before
2609 pushing a dummy frame now.
2611 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
2612 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
2613 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
2614 the starting address (actual frame address) of a frame.
2615 * rs6000-tdep.c: modifications to function_frame_info() to see if
2616 function reserves a frame pointer register (alloca register)
2617 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
2618 FRAME_LOCALS_ADDRESS has been updated to support debugging of
2619 functions with alloca() calls.
2621 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
2623 * xm-sysv4.h: Provide definitions/prototypes for host environment
2624 functions for which no definitions or prototypes are provided in
2625 any currently included gdb or host environment header files.
2626 For SVR4, this currently includes malloc and realloc, which cannot
2627 be portably prototyped in any gdb include file.
2629 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
2631 * buildsym.h: Remove obsolete variable file_stabs.
2633 * Makefile.in: Move place where configure merges in host-
2634 and target-dependent fragments later, so the latter
2635 can override (say) GNU_MALLOC.
2636 * config/mh-rs6000: Use system malloc. Otherwise, I
2637 ended up with *two* incompatible versions of malloc
2638 (functions in libc would call the malloc in libc).
2639 I assume this is a shared library problem.
2641 * remote.c: Fix (presumed) typo.
2642 * objfiles.c: Use xmalloc/xrealloc instead of
2643 malloc/realloc (since the latter are no longer declared).
2645 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
2646 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
2647 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
2648 handle individual registers.
2649 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
2650 correctly in case it wasn't cached yet. (A problem showed up
2651 after fetching individual registers.)
2652 * buildsym.c: Disable type_synonym_name's type name overwriting
2653 in cases it is unnecesary. rs6000 portation doesn't use
2654 type_synonym_name, and it used to nullify type names
2655 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
2656 type's name as soon as space for that type is allocated.
2657 * xcoffread.c: ignore a section's lineno information if it is
2658 not `.text'. (In rs6000 bfd portation integration, skipping over
2659 `.pad' sections are ignored since it was in machine independent
2660 part of the code. Thus, a problem of fake sections with invalid
2661 lineno information arised.)
2663 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
2664 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
2665 * rs6000-tdep.c: make function_frame_info() work whether or not
2666 reading from a core file.
2667 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
2669 * infrun.c. main.c, printcmd.c. symtab.c:
2670 More changes from IBM for rs6000.
2673 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
2675 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
2676 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
2677 Merge in changes (mostly from IBM) for RS6000.
2678 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
2679 More changes from IBM for RS6000. These are in machine-
2680 independent code, and probably could do with some cleaning
2681 up. The most questionable of these are #ifdef IBM6000.
2682 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
2683 to single_step() (for consistency with rs6000 and i860).
2684 * utils.c: Allow the 1st arg to xrealloc to be NULL
2685 (in which case do malloc). This removes the need for
2686 some tests in xcoff code (and perhaps other places?).
2687 * coffread.c: Removed variables last_source_file,
2688 type_vector, and type_vector_length as these are now
2689 defined by buildsym.[ch].
2690 * defs.h: Remove prototypes for malloc and realloc, since
2691 these should only be used to implement xmalloc and xrealloc,
2692 and they conflict with <stdlib.h> in AIX - where they
2693 return void* even when __STDC__ isn't defined. Sigh.
2694 * munch: Recognize *initialize* in data as well as text
2695 (AIX uses data). Also, incorporate a patch from Garrett
2696 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
2697 much more sensible, by only trying to match the name of
2698 the initialize_foo function, and not the junk before it.
2700 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
2702 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
2703 unless symbol table indicates that something has changed.
2705 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
2707 * remote.c: Make it work for embedded MIPS. Increase buffer
2708 size, and use throughout. Round buffer size up if too many regs.
2709 Support baud rate setting and try for an 8-bit path. If
2710 interrupted while waiting for target, send a ^C down the wire.
2711 Avoid single-byte reads.
2712 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
2714 * mips-xdep.h: Avoid the embedded regs when on Unix.
2716 * mipsread.c: Byte-swap the symbol table structures, using
2717 routines from ecoff.c, to read a symbol table written in any
2718 of the four possible byte orders.
2719 * configure.in (mips-big-* target): Same as Sony News.
2720 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.
2721 * ecoff.c: New file for symbol swapping routines.

2726 all-breakpoints' command.
2727 * (get_number): Allow users to enter negative breakpoint numbers.
2728 * (breakpoint_1): Reformat display of 'info break' to show new
2730 * (create_longjmp_breakpoint, breakpoint_re_set,
2731 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
2732 symfile.c (syms_from_objfile): Re-do
2733 insertion of longjmp breakpoints. Move all code into
2734 breakpoint_re_set, and call that instead of
2735 create_longjmp_breakpoint in symfile.c.
2737 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
2739 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.

2752 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
2753 copyrights to '92, changed some from Cygnus to FSF.

2763 * Makefile.in (VERSION): Roll to gdb-4.4.4.
2765 * symfile.c (symbol_file_command): strcmp => !strcmp.
2766 * breakpoint.h: Move prototypes to follow enum definition they need.
2767 * breakpoint.c, infrun.c: Lint.
2768 * printcmd.c: Use `enum enable' rather than `enum
2770 * mipsread.c: First pass at making it compile with the new
2771 objfile changes. Probably seriously broken still, but it
2774 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

3167 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
3168 Remove to_call_function and target_call_function, since it
3169 always calls the same thing (call_function_by_hand).
3170 * core.c, exec.c, solib.c: Rename target_ops sections =>
3172 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
3173 target.h: target_kill takes no args.
3174 * language.c (language_info): Scaffolding to allow briefer
3175 messages when the current language changes. FIXME.
3176 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
3177 complaints about volatile functions.
3178 * xm-sysv4.h (HAVE_MMAP): Define.
3180 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)

3195 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
3196 DIE's. Add new function read_tag_pointer_type() to read them.
3198 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
3199 When creating a new user defined type, check to see if a partial
3200 type already exists, and if so, bash it to fit.
3202 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
3204 * coffread.c (decode_base_type): Pass long, not union.

3223 number for double pseudo-registers.
3225 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
3227 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr

3229 <mccanne@horse.ee.lbl.gov>.
3231 * exec.c (set_section_name): Pass arg to exec_files_info;
3232 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
3234 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
3236 * main.c (print_gdb_version): Copyright msg: only this year.
3237 (cd_command): Avoid changing current_directory on error.
3239 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
3241 * mipsread.c (parse_partial_symbols): Handle dependencies
3242 between partial symbol tables (when not doing stabs-in-ecoff).
3243 (This used to be handled by parse_fdr, but parse_fdr was
3244 incompatible with handling stabs-in-ecoff, so the code
3245 was re-written to not use parse_fdr. Unfortunately,
3246 the logic to handle dependencies was overlooked.)
3248 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
3250 * coffread.c (read_enum_type): Use the size of a target int when
3252 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
3254 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
3255 * symtab.c (lookup_reference_type, lookup_ptr_type): use
3256 TARGET_PTR_BIT to determine size of a pointer
3257 * values.c (unpack_long): when unpacking a REF or a PTR don't
3258 assume the size of the type.
3260 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
3262 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
3263 looking at its members. Improve guess between struct and union,
3264 only assuming union if multiple members have offsets of zero.
3266 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
3268 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
3269 (This is just for clarity - and one day permitting us to
3270 change FP0_REGNUM from 38 to 32, which would make more sense.)
3271 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
3272 register numbers in stabs-in-ecoff get handled correctly.
3274 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
3276 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
3277 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
3278 into BSD and Ultrix.
3280 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
3282 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
3284 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
3286 * Makefile.in: Increment version to 4.4.1.
3287 * main.c (print_gdb_version): Update copyright notice.
3289 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
3291 * mipsread.c: Prepend "struct " to the names of structure
3292 types, and similarly for enums and unions. (This used
3293 to be done, but got lost in the re-write to "guess" the
3294 difference between enum/struct/union.)
3295 Also, guess that a tag is an enum if the first member
3298 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
3300 * xm-vax.h: #ifndef ultrix around #include of endian.h and
3303 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
3305 * Projects: Patching executables is done.
3306 * Makefile.in (VERSION): Roll to gdb-4.4.
3307 * README, WHATS.NEW: Update for gdb-4.4.
3309 * symfile.c (reread_symbols): Whenever we reread one object
3310 file's symbols, we must restart the scan, because the object_files
3311 chain has been permuted.
3313 * exec.c (exec_files_info): Split out into print_section_info.
3314 Print BFD filename of each section if it's not the default one.
3315 * core.c (core_files_info): Call print_section_info.
3317 * xm-vax.h: Include a few system header files whose definitions
3318 must precede defs.h.
3319 * language.c, language.h: Make some things const.
3320 * expression.h, main.c: const spreads like ooze.
3322 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
3323 since BREAKPOINT values can be >0x80.
3325 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
3327 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
3329 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
3331 * sparc-pinsn.c: Remove kludge for preferring architectures.
3332 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
3333 and forever. Add `add' instruction to the set that get checked
3334 for a preceding `sethi' in order to print an absolute address.
3335 Corresponding changes in ../include/opcode/sparc.h needed
3336 to eliminate garbage instructions.
3338 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
3340 * mipsread.c (parse_partial_symbols): Make sure partial
3341 symbols are created for external symbols (as used to be
3342 the case). This is a bit of a pain with the mips-coff.
3343 It uses a table which points to all of the external
3344 symbols belonging to a particular FDR or psymtab.
3345 Once we've generated this table, we might as well save
3346 it, and then use it in psymtab_to_symtab_1 to find
3347 the symbols to pass to parse_external().
3348 * symfile.c, symfile.c: New function start_psymtab_common
3349 to share the common parts of allocating a new psymtab
3350 for dbxread, mipsread (and later dwarfread). Its code
3351 was pulled out from start_psymtab in dbxread.c.
3352 * dbxread.c (start_psymtab): Use start_psymtab_common().
3354 * valprint.c (val_print): If there is an error when trying
3355 to print a string, check to see if there really is a problem
3356 by reading just one character. If that works, assume
3359 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
3361 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
3362 cypress, v8 mnemonics in that order.
3364 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
3366 * sparc-pinsn.c: Put the qsort() back in.
3368 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
3370 * findvar.c (read_register, write_register): Handle machines
3371 where REGISTER_TYPE is not the same size as "int".
3373 Handle debug symbols in dynamically loaded (relocated) code:
3375 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
3376 offset to process_one_symbol.
3377 (process_one_symbol): Take new offset parameter. Add it into
3378 appropriate symbol types to relocate symbols to loaded addresses.
3379 Handle all possible symbol types, and complain() about types that
3380 we don't expect to see.
3381 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
3382 process_one_symbol (FIXME, should pass real offset).
3386 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
3388 (set_breakpoint, break_command_1, until_break_command,
3389 catch_command_1, breakpoint_re_set_one): Use it.
3390 * symtab.h (resolve_sal_pc): Declare.
3391 * infcmd.c (jump_command): Use resolve_sal_pc.
3393 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
3395 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
3397 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
3399 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3400 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
3401 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
3403 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
3405 * dbxread.c (process_one_symbol): Make a first cut at handling
3406 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
3408 * symtab.c (find_pc_line): Fix stepping into and out of #included
3411 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
3413 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is

3507 nexting over recursive function calls.
3509 * target.c (target_read_string): Create this routine to read null
3510 terminated strings from the target. It deals with running off the

3532 freescope, buildblock closescope, record_line, add_symbol_to_list,
3533 gatherblocks, make_blockvector): Extensive changes to switch
3534 to generic symbol table building code in buildsym.c. Remove
3535 scope tree structures and functions, symbol table building
3536 functions, and lots of other small changes.

3559 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
3560 to reflect actual locations of opcode files, so TAGS target will
