1992-03-28Add OBJF_SYMS flag and use it to decide whether or not we have alreadyFred Fish3-51/+60
tried to read symbols from a file, for mapped objfiles. This fixes a memory leak (actually a constant memory growth) due to reading symbol files with no debug info and thus generating no psymtabs or symtabs. Most typically happened with shared libraries.
1992-03-27Misc cleanups from code review.John Gilmore7-49/+48
1992-03-27Mostly changes to dbxread.c to preserve stringtab's on a per-objfileFred Fish5-261/+331
basis, for use in expanding psymtabs to full symtabs. See ChangeLog for other details.
1992-03-26 * rs6000-pinsn.c: Make dis-assembly output more likePer Bothner1-50/+43
other targets: Don't print instruction in hex before the assembly; use print_address to print out jump destinations.
1992-03-26 * c-exp.y, gdbtypes.h: Add builtin_type_signed_char.Per Bothner4-0/+21
* cplus-dem.c: Support "Sc" meaning "signed char".
1992-03-25* configure.in: fix iris/iris3.Stu Grossman2-1/+5
1992-03-25 * command.c, main.c (various places): Use ctype.h macrosPer Bothner2-7/+15
(such as isupper(x)), instead of hard-wiring in ASCII-isms (such as (x >= 'A' && x <= 'Z')). (There are still more of these in other files.) * main.c (defined_command): Lower-case the user's new command before entering it. Needed because command lookup is case-insensitive (and also lower-cases). (Based on Metin's earlier patch.)

1992-03-25* infcmd.c (step_1): Call disable_longjmp_breakpoint at the rightStu Grossman1-1/+4
time.
1992-03-25* xm-mips.h: declare strdup for ultrix.Stu Grossman2-0/+6
1992-03-25* mipsread.c (fixup_sigtramp): Make sure that current_objfile is setupStu Grossman1-0/+7
when calling new_symbol. * mips-tdep.c (mips_frame_chain): Use symfile_objfile instead of current_objfile.
1992-03-24 * config/rs6000.mh: Update (for Fred's new mmalloc)Per Bothner4-6/+14
flags to disable use of GNU malloc/mmalloc. * munch: Change SYSV rule to allow .text before the label, as well as after, to work for AIX. * gdbtypes.h: Minor clarifiction.
1992-03-24Fixed a place where dbx symbol name continuation was appearing in anMichael Tiemann2-0/+6
unexpected place, causing the `Trace' type in gperf/main.o to be mis-parsed.
1992-03-24* mips-tdep.c: include symfile.h and objfiles.h to fixStu Grossman2-1/+8
compilation errors.
1992-03-23 * valops.c (value_struct_elt_for_reference): Added 'offset'Per Bothner1-0/+6
parameter to handle multiple inheritance. * eval.c, value.h: Update accordingly.
1992-03-21Many changes, most related to creating entry point information on a per-objfileFred Fish32-185/+458
basis. See comments in objfiles.h and details in ChangeLog. Also remove redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and use a default definition in frame.h.
1992-03-20More C++ improvements (pointers to members, qualified names). See ChangeLog.Per Bothner6-379/+574
1992-03-19 * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c,Fred Fish10-310/+520
elfread.c (coff_symfile_finish): Add function, prototype, and add to the xxxx_sym_fns struct for each file type. Also reformat the xxxx_sym_fns vector to a standard format and add comments. * coffread.c, mipsread.c, xcoffread.c, coffread.c, dbxread.c, elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read): Pass pointer to struct objfile rather than pointer to sym_fns. Change references inside each function accordingly. Allocate any symbol file specific info in the per-objfile memory region. * dbxread.c (free_and_init_header_files): Break function into free_header_files(), called from dbx_symfile_finish(), and init_header_files(), called from dbx_new_init(). * dbxread.c (dbx_new_init): Move deallocation things to new dbx_symfile_finish function. * elfread.c (elf_new_init): Call buildsym_new_init(). * objfiles.c (free_objfile): Call the appropriate symfile_finish() routine for the objfile before deallocating other stuff. * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg. * symfile.h: Move struct sym_fns to before struct objfile def. Add sym_finish function pointer and change prototypes of other function pointers to reflect passing struct objfile pointer rather than struct sym_fns pointer. * symfile.c: Remove now obsolete symtab_fns pointer. * symfile.c (symfile_init): Renamed to find_sym_fns, and now only locates the correct sym_fns struct for the given objfile. * symfile.c (syms_from_objfile, symbol_file_add): Restructured for better support of mapped symbol tables. * symfile.c (symbol_file_command): Remove obsolete code using symfile_fns. * symfile.h: Remove duplicate declarations for symfile_objfile, entry_point, and object_files. * target.c (target_info): Compare symfile_objfile to NULL. * xcoffread.c (aixcoff_new_init): Move deallocation stuff to aixcoff_symfile_finish().
1992-03-19Add and use definition for IN_SOLIB_TRAMPOLINE which allows wait_for_inferiorFred Fish2-0/+20
to test whether or not it has stepped into the glue that binds an application to a shared library routine.
1992-03-19 Some improvements to g++ debugging.Per Bothner4-54/+192
* symtab.c (list_symbols): demangle before pattern matching. * symtab.c: Other fixes to improve handing of operators. * valprint.c (type_print_base): Fix test for constructor. * values.c (value_static_field): Allow evaluation of CLASS::METHOD, returning a function pointer.

to keep.
1992-03-18Changes to implement the -mapped and -readnow options for commands thatFred Fish11-621/+579
read symbol tables.
1992-03-15Remove unused file mtrace.awk, remove entries from .Sanitize forFred Fish2-8/+1
mtrace.awk and previously removed files.
1992-03-15These files are replaced by the mmalloc library.Fred Fish1-0/+3
1992-03-15Missed in last checkin.Fred Fish1-3/+8
1992-03-15Globs of changes. See the ChangeLog for details. Most related toFred Fish28-915/+1980
using the new mmalloc package.
1992-03-14Only enable compilation of debugging functions when IBM6000 is definedFred Fish2-1/+6
as well as DEBUG. Fails to compile otherwise.
1992-03-14Add config directory to list of things to keep.Fred Fish1-0/+1
1992-03-14* mipsread.c (mipscoff_symfile_read): Eliminate a lot ofJohn Gilmore2-15/+19
useless code, including an lseek to an uninitialized variable. Reported by Jim Williams <jimbo@wrs.com>.
1992-03-14pass MAKEINFO down on infoK. Richard Pixley2-27/+49
1992-03-14(1) GDB 4.5: another Grossman/Gilmore co-production!Roland Pesch1-8/+67
(2) Add fnf to GDB credits for SVr4 stuff. (Need to sift ChangeLog again for more recent credits). (3) document "mapped", "readnow" keywords (with file or symbol-file commands; for now no mention of add-symbol-file in this context), -m and -mapped cmd-line options, and associated explanations.
1992-03-14Run TeX *three* times to get better index, xrefs.Roland Pesch1-0/+1
1992-03-13(1) Document printmsyms; slight clarifications to description of printsyms,Roland Pesch1-13/+57
printpsyms. (2) Fix errors found by makeinfo. (3) Initial docn for "info proc" and its subcommands. Should probably be expanded somewhat after implementation complete.

1992-03-12.Sanitize: reflect removal of gdb-all.texi from repositoryRoland Pesch4-68/+228
lucid.m4: config for Lucid/NCR (like "all.m4" but also turns on _LUCID__) none.m4: turn _LUCID__ off by default gdb.texinfo: 1) Use bold rather than italic for user input in intro, to avoid discord with meta-variable convention throughout manual (jim@wrs.com suggestion). 2) Some mumbling about using GDB under Energize/Cadillac. (conditionalized on _LUCID__, not included yet in general-doc config) 3) more remarks about debugging optimized code, incl vanishing unused vars (rms/gnu/net suggestion). 4) @emph replaces @i in a few spots (emphasis should affect info file as well as printed manual). 5) "memory tracing", "breakpoint on variable modification" index entries added, pointing to watchpoints (gnu suggestion). 6) Less passive, more index entries, in breakpoint-number description 7) doc new convenience var $bpnum (due to grossman?) 8) Update "info breakpoints" to describe new Grossman format; note now synonymous with "info watchpoints". 9) Describe negative (GDB internal) breakpoints and new "info all-breakpoints" 10) Slight change to description of colon-colon GDB expression notation, describing function::var as well as file::var and noting var is static (lmb question, gnu suggestion) 11) Doc Per's new &(&foo) for debugging C++ 12) Rephrase paragraph in configure appendix to avoid overfull box (in *large* format!) 13) Additional warning re VPATH feature required for --srcdir= config. (gnu suggestion)
