   1 Fri Feb  4 15:53:18 1994  Steve Chamberlain  (sac@cygnus.com)
   2
   3         * h8500-tdep.c (saved_pc_after_call): The size of the
   4         pc is memory model dependent. (segmented_command,
   5         unsegmented_command, _initialize_h8500_tdep): New commands to
   6         change memory model.
   7         * remote-7000.c (initialize_remote_e7000): Change name of snoop
   8         command.
   9
  10 Fri Feb  4 07:41:13 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  11
  12         * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
  13         as CORE_ADDR to match definition in rs6000-tdep.c.
  14
  15 Fri Feb  4 01:14:20 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  16
  17         * dwarfread.c (process_dies):  Skip nested TAG_compile_unit DIEs.
  18         * dwarfread.c (add_partial_symbol):  Do not enter opaque aggregate
  19         definitions into the psymtab.
  20
  21 Thu Feb  3 12:38:58 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  22
  23         * m68k-stub.c: Treat mc68332 like mc68020 most places.  Provide
  24         a special exceptionSize for the 68332.
  25
  26         * remote-udi.c (udi_attach): If no arguments, print error.
  27
  28 Thu Feb  3 17:34:05 1994  Fred Fish  (fnf@cygnus.com)
  29
  30         * Makefile.in (VERSION):  Bump to 4.12.1
  31         * NEWS, README:  Update to match 4.12 release.
  32
  33 Thu Feb  3 12:38:58 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  34
  35         * command.c (empty_sfunc): New function.
  36         (add_set_cmd): Use it instead of not_just_help_class_command.
  37         (not_just_help_class_command): Change calling convention back to
  38         what it was before yesterday's change.
  39
  40         * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
  41         of the type if present.
  42
  43 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  44
  45         * printcmd.c (decode_format): Don't blithely set the size for
  46         an address to 'w'.  Make it 'g' or 'h', depending on TARGET_PTR_BIT.
  47
  48         * defs.h: Just typedef CORE_ADDR to bfd_vma.  Include bfd.h.
  49         If BFD64, make a LONGEST a BFD_HOST_64_BIT.
  50         * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
  51         always just check against INT_MIN and INT_MAX (this also fixes things
  52         if sizeof (long) > sizeof (int), e.g. Alpha).
  53         * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
  54         Don't define LONGEST or BUILTIN_TYPE_LONGEST.
  55         * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
  56         BUILTIN_TYPE_UNSIGNED_LONGEST.
  57         * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
  58         longest_int and longest_unsigned_int.
  59         * value.h (struct value): Just align to LONGEST, rather than worrying
  60         about CC_HAS_LONG_LONG.
  61         * valarith.c (value_binop): Figure out type ourself based on
  62         sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST.  The
  63         point is that we don't depend on CC_HAS_LONG_LONG anymore.
  64         * valprint.c (val_print_type_code_int): Just call
  65         extract_unsigned_integer directly, rather than going through
  66         unpack_long.
  67         * printcmd.c (decode_format): Remove code which would sometimes
  68         change 'g' size to 'w' for integers.  print_scalar_formatted handles
  69         printing huge integers well enough, thank you.
  70
  71         * command.c (add_set_cmd, not_just_help_class_command): Change
  72         to make this the sfunc, not cfunc, since that is how we call it.
  73         * command.h: Comment difference between sfunc and cfunc.
  74         * demangle.c (set_demangling_command): Add third arg since that
  75         is how it is called.
  76         (_initialize_demangler): Use sfunc, not cfunc, for
  77         set_demangling_command, since that is how it is called.
  78         Remove show_demangling_command; it has no effect.
  79
  80         * command.c (shell_escape): Report errors correctly (with error
  81         message from strerror).
  82
  83 Wed Feb  2 14:35:41 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  84
  85         * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
  86         x_scnlen.l rather than x_scnlen to match corresponding change in
  87         coff/internal.h.
  88
  89 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  90
  91         * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
  92         Change comments regarding TYPE_CODE_BOOL.
  93         * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
  94         regardless of the language.
  95         (value_true): Just call value_logical_not regardless of language.
  96         * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
  97         Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
  98         * language.h: Improve comment for la_builtin_type_vector.
  99         * m2-lang.c (_initialize_m2_language): Don't add any fields to
 100         builtin_type_m2_bool.
 101
 102 Tue Feb  1 17:13:32 1994  Kevin Buettner (kev@cujo.geg.mot.com)
 103
 104         * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
 105         Define IN_SIGTRAMP and backtrace correctly through signal handlers.
 106
 107 Tue Feb  1 22:13:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 108
 109         * procfs.c (wait_fd):  Handle EINTR error return from PIOCWSTOP ioctl
 110         by restarting the ioctl.
 111
 112 Tue Feb  1 16:16:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 113
 114         * target.h (target_wait): Add comment about calling
 115         return_to_top_level.
 116
 117 Tue Feb  1 12:21:00 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 118
 119         * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
 120         additional arguments.
 121         * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
 122
 123 Mon Jan 31 16:10:41 1994  Stu Grossman  (grossman at cygnus.com)
 124
 125         * sparc-stub.c:  Remove unnecessary #include of memory.h.
 126
 127 Mon Jan 31 12:12:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 128
 129         * mips-tdep.c: Remove code which sets saved_regs from
 130         init_extra_frame_info and put it in new function mips_find_saved_regs.
 131         (READ_FRAME_REG): Remove macro and replace uses with the expansion.
 132         * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
 133         check if it is NULL and call mips_find_saved_regs if so.
 134
 135         * remote-mips.c: Use unfiltered, not filtered, output most places.
 136
 137         * blockframe.c (get_prev_frame_info): Detect and stop an infinite
 138         backtrace.  Revise comments.
 139
 140 Mon Jan 31 09:40:33 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 141
 142         * mdebugread.c (parse_procedure):  Remove _sigtramp kludges for
 143         alpha and irix. The _sigtramp case has to be handled properly
 144         in the tdep files if we have no ecoff debugging info.
 145         * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
 146         mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
 147         without PC_REGNUM kludge.
 148         * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
 149         Clean up handling of mips sigtramp frames, improve comments.
 150
 151 Sat Jan 29 23:25:57 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 152
 153         * paread.c (read_unwind_info): Fix typo.
 154
 155         * paread.c (pa_symtab_read): Update the "check_strange_names"
 156         filter to match GCC's current output.  Filter out section symbols
 157         (which the HP linker sometimes puts in the wrong place).
 158
 159 Sat Jan 29 07:44:59 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 160
 161         * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
 162
 163         * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
 164
 165         * Makefile.in: Remove all references to sparcly-nat.c.
 166
 167         * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
 168         remote-sim.h directly, rather than via $(remote_utils_h).  This avoids
 169         duplicating serial.h and target.h.
 170
 171         * Makefile.in: Don't set M_INSTALL and M_UNINSTALL.  These variables
 172         are not used anywhere (a 5 Oct 1993 change removed the uses).
 173
 174         * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
 175         * config/m68k/es1800.mt: Add comment.
 176         * remote-es.c: Extensive changes to update to current conventions.
 177
 178         * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
 179         If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
 180         to achieve the desired timeout.
 181         * serial.h (serial_t): Add field timeout_remaining.
 182
 183 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 184
 185         * c-exp.y (yylex): Reenable nested type code.
 186
 187 Fri Jan 28 15:40:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 188
 189         * a29k-tdep.c (examine_tag): Add comment regarding argcount.
 190
 191         * remote-mips.c (mips_ops): Fix docstring.
 192
 193         * remote-bug.c (bug_ops): Remove spurious newline from docstring.
 194
 195         * config/m68k/tm-monitor.h: Changes to bring this into accordance
 196         with the old tm-m68k-em.h:
 197         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
 198         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
 199         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
 200         Add FIXME regarding GET_LONGJMP_TARGET.
 201
 202         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
 203         * infptrace.c (kill_inferior): Add comments.
 204         * main.c (quit_command): Call target_close after we kill or
 205         detach.
 206         * remote-udi.c (udi_close): Don't error() if QUITTING.
 207
 208 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
 209
 210         * configure.in: Make m68k-coff and aout add monitor support in
 211         addition to the standard serial support.
 212
 213 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 214
 215         * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
 216         index indexNil.
 217
 218 Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 219
 220         * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
 221         * elfread.c (record_minimal_symbol_and_info),
 222         dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
 223
 224 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 225
 226         * i386-stub.c: Add ".text" right before "mem_fault:".
 227
 228         * main.c (baud_rate): Add FIXME comment about printing -1 value.
 229
 230         * remote-utils.c (usage): Fix message to be accurate and conform
 231         more closely to normal conventions.
 232
 233         * remote-utils.c (gr_files_info): Have the exec_bfd test control
 234         whether to show information about exec_bfd, and not control whether
 235         to show information about device and speed.
 236
 237         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
 238         usage message, don't dump core.
 239
 240         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
 241         for variable size array.
 242         (bug_fetch_register, bug_store_register): Rename "value" to
 243         "fpreg_buf" because some compilers don't like variables whose
 244         names are the same as types.
 245         (bug_store_register): Use a cast when converting char * to
 246         unsigned char *.
 247
 248         * symmisc.c (maintenance_print_symbols): Don't refer to the name
 249         of the command in error message (the text was referring to the old
 250         name of the command).
 251
 252         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
 253
 254         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
 255         full details on structure elements without names.  This partially
 256         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
 257         of those changes was accidental.
 258
 259         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
 260         defined, make it an error to specify a single argument which is not
 261         a frame number.
 262
 263         * Makefile.in (version.c), main.c (print_gdb_version): Use
 264         host_alias and target_alias, not host_canonical and
 265         target_canonical, to print configuration.
 266
 267 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 268
 269         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
 270         of builtin_type_long.  It is necessary to get a type which is
 271         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
 272
 273         Fix many sins which will come up in 32 bit x 64 bit GDB, and
 274         various miscellaneous things discovered in the process:
 275         * printcmd.c, defs.h (print_address_numeric): New function.
 276         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
 277         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
 278         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
 279         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
 280         Use it.
 281         * utils.c, defs.h (gdb_print_address): New function.
 282         * expprint (dump_expression), gdbtypes.h: Use it.
 283         * breakpoint.c (describe_other_breakpoints),
 284         symmisc.c (dump_symtab, print_symbol):
 285         Use filtered not unfiltered I/O.
 286         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
 287         just run gdb under a debugger for this (and it had problems with
 288         printing addresses, how to print b->shadow, etc.).
 289         * buildsym.c (make_blockvector), core.c (memory_error),
 290         exec.c (print_section_info), maint.c (print_section_table),
 291         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 292         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 293         Add comments saying code is broken.  Marked with "FIXME-32x64".
 294         * dbxread.c (process_one_symbol), partial-stab.h (default),
 295         remote-vx.c (vx_run_files_info):
 296         Don't cast int being passed to local_hex_string.
 297         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 298         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 299         only being a long.
 300         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 301         and LOC_LOCAL.
 302         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 303         * source.c: Include <sys/types.h> regardless of USG.
 304
 305 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 306
 307         * valops.c (value_assign):  Set `type' after coercing toval.
 308         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 309         Use extract_unsigned_integer to get the address of a reference.
 310
 311 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 312
 313         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 314         AIX can use ? instead of \ for continuation.  Deal with it.
 315
 316         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 317         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 318         the HP compiler in ANSI mode doesn't like.
 319
 320         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 321         based on USG, rather than defining HAVE_SIGSETMASK to an
 322         expression containing defined.  Having a macro used in #if expand
 323         to an expression containing "defined" is undefined according to
 324         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted

 339         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 340         passing them to print_387_status.
 341         (print_387_status): Don't subtract top from 7 before using it.
 342         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 343         from 7; the above explains it.

 358         cleanup chain, not directly.
 359
 360         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 361         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 362         munging the timeout due to the limited range of c_cc[VTIME].
 363
 364         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
 365         * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),

 380         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 381         tm-sparc.h so they can be overridden if necessary.
 382

 384
 385         * lynx-nat.c:  Add Sparc support.

 394         * rs6000-pinsn.c: Use the new disassembler in the opcodes
 395         directory.  Old code was discarded, since the new opcode table has
 396         a different format.
 397

 438         struct section_offsets *, not a (nonexistent) struct section_offset *.
 439
 440         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 441         internal_xcoff_symtab, not an array of one of them.  Change lots of
 442         "main_aux" to "&main_aux" and so on.
 443
 444         * coffread.c, xcoffread.c: Include <coff/internal.h>
 445         before "symfile.h".

 450

 452
 453         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 454         a completely gratuitous difference between xcoffread.c and coffread.c).
 455

 460
 461         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 462         breakpoint.c (bpstat_what): Move step_resume from its own field of
 463         the struct bpstat_what into the main_action.  Make it override
 464         other breakpoints.  This is a conservative change in the sense
 465         that before the step resume breakpoint was a breakpoint.c
 466         breakpoint, hitting the step resume breakpoint overrode even
 467         calling bpstat_stop_status.
 468
 469 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

 474         a call dummy, handle the starting source line number on a line
 475         boundary like backtracing through sigtramp.
 476         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 477         for call dummy frame right.  Remove old test for dummy frame,
 478         it has been unused at least since gdb-3.5.
 479         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 480         of the dummy frame.

 489         Use ugly casts to avoid enumvar < enumvar or enumvar++.
 490

 498         signals for which stop and print are cleared by default.

 512         unwind table entries.
 513         (read_unwind_info): Rewrite to remove dependency on host endianness.
 514         Read in data from the $UNWIND_END$ subspace which contains linker
 515         stub unwind descriptors.  Merge that data into the basic unwind
 516         table.
 517
 518         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 519
 520 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 521
 522         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name

 548         Add various files which were added to GDB recently.

 560
 561         * main.c (show_commands):  Make return type of extern
 562         history_get be HIST_ENTRY, rather than struct _hist_entry.
 563         (The latter loses with the upcoming merged readline.)

 581         builtin_type_long_long if builtin_type_long isn't big enough or if
 582         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 583
 584         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 585         Print our "()" first, then recurse for the target type.

 643         tag.
 644
 645         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 646         is on, call find_pc_function rather than relying just on the minimal
 647         symbols (probably only matters for symbol readers which don't put
 648         statics in the minimal symbols, but changing this strikes me as
 649         not conservative enough).
 650         Initialize name_location in all cases.
 651         If no symbol and no msymbol, don't print anything symbolic.
 652
 653         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 654
 655 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 656
 657         * printcmd.c (print_address_symbolic):  Make it search the
 658         symtabs for variables as well as functions.  Add `set print

 660         Print line numbers for data items as well as functions.
 661
 662         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 663         address, if a symbol is found (take two more args pointing to
 664         where to store these results).
 665
 666         * symtab.h (find_addr_symbol):  Add prototype.

 674 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 675
 676         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 677         compiler generated tag names.
 678         * mdebugread.c (parse_type):  Handle cross references to qualified
 679         aggregate types.
 680         * valops.c (value_struct_elt):  Improve error message if the
 681         address of a method is requested from an object instance.
 682         * valops.c (search_struct_method):  Make name_matched non-static
 683         to get it initialized correctly.
 684         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 685         exclude segment register which are not writable on newer SCO versions.
 686
 687 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 688
 689         * go32-xdep.c: Remove unused function uerror.
 690         (sigsetmask): Declare return type.  Declare argument (to match the
 691         way it is called).  Explicitly return 0.
 692
 693 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 694
 695         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 696         partial_symbol):  Shrink the storage sizes of symbols, by making
 697         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 698         enums and small ints to the end of each struct to improve
 699         alignment, and switching the section number from int to unsigned
 700         short.
 701
 702 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 703
 704         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 705         symbol associated with an address.  It does so by exhaustive
 706         search of the symtabs, so it's slow but complete.
 707
 708 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 709
 710         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 711         to [0,0] rather than [0, end of first source file].  This avoids
 712         problems with other parts of GDB looking for linetables in the
 713         _globals_ symtab.  Eliminate variables num_object_files and
 714         first_object_file_end.
 715
 716 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 717
 718         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 719         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 720         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 721         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 722         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 723         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 724         (SETUP_ARBITRARY_FRAME):  Define.
 725
 726 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 727
 728         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 729
 730 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 731
 732         * remote-udi.c (udi_resume): Correct prototype.
 733
 734 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 735
 736         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 737         hppa_frame_find_saved_regs.
 738         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 739         (prologue_inst_adjust_sp): New function.
 740         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 741         (skip_prologue): Completely rewrite to use unwind information.
 742         (hppa_frame_find_saved_regs): Likewise.
 743
 744 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 745
 746         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 747         to convert a signal number with appropriate bounds checking.
 748
 749         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 750
 751 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 752
 753         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 754         print a newline to end the display anyway.
 755
 756         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 757         coprocessor status regs) when popping a frame.  This fixes
 758         float exceptions that occur after calling inferior functions.
 759
 760         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 761         Read and write the fsr (float status register) to/from the child
 762         process along with the float regs.  Remove Peter Schauer's change
 763         of May 24 '93, which has higher overhead and doesn't solve the
 764         real problem (which was that FSR wasn't being set).
 765
 766 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 767
 768         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 769         stack overflow check isn't right after the register stack
 770         adjustment instruction.  Metaware R2.3u compiler moves other
 771         things in front of it.  This fix isn't perfect but is what's
 772         running.
 773
 774 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 775
 776         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 777
 778         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 779         character filenames.
 780         * configure.in: Change accordingly.
 781
 782 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 783
 784         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 785         _filtered io routines from these two files.
 786
 787 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 788
 789         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 790         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 791         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 792         DEC c89.
 793         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 794
 795 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 796
 797         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 798         printing to gdb_stderr.
 799
 800         * remote-udi.c (udi_kill): Don't close the connection, just set
 801         inferior_pid to zero.
 802         (udi_mourn): Call remove_breakpoints.
 803
 804         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 805
 806         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 807
 808 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 809
 810         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 811
 812         * remote-bug.c: At the start of each section, reset srec_frame
 813         back to 160.
 814
 815         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 816         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 817         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 818         code which looks for those two waitkinds.  Use switch statement.
 819         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 820         CHILD_SPECIAL_WAITSTATUS.
 821
 822         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 823         * Move target_signal_from_host, target_signal_to_host, and
 824         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 825         * target.c: Include "wait.h" and <signal.h>.
 826         * target.h, infrun.c (proceed), proceed callers: Pass new code
 827         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 828         enums being treated as unsigned and is cleaner.
 829         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 830         TARGET_SIGNAL_0.
 831         * infcmd.c (signal_command), infrun.c (signals_info):
 832         Don't allow user to specify numeric equivalent of
 833         TARGET_SIGNAL_DEFAULT.
 834
 835 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 836
 837         * config/alpha/alpha-netware.mt:  New target support for Alpha
 838         running Netware.
 839         * configure.in:  Add alpha-*-netware* target.
 840
 841 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 842
 843         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 844
 845 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 846
 847         * target.h: Add enum target_waitkind, enum target_signal, and
 848         struct target_waitstatus.  Change status argument to target_wait to
 849         be struct target_waitstatus * instead of int *.
 850         * target.h, infrun.c, all targets: Change type of signal arguments
 851         to resume(), proceed(), and target_resume() from int to enum
 852         target_signal.
 853         * All targets (*_wait, *_resume): Change accordingly.
 854         * infcmd.c (program_info, signal_command), throughout infrun.c,
 855         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 856         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 857         signal code stuff right with the new signals would be non-trivial).
 858         * inferior.h (stop_signal): Make it enum target_signal not int.
 859         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 860         target_signal_from_name): New functions.
 861         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 862         store_waitstatus): New functions.
 863         * procfs.c (procfs_notice_signals): Use them.
 864         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 865         print_fault.
 866         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 867
 868         * objfiles.c (build_objfile_section_table): Don't abort() if
 869         objfile->sections is already set.
 870
 871         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 872         to match recent change to exec.c.
 873
 874         * Version 4.11.3.
 875
 876         * main.c (print_gdb_version): Change year to 1994.
 877
 878         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 879         * Makefile.in (NONSRC): Add ChangeLog-93.
 880
 881 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 882
 883         * stabsread.c (read_type): Allow defining several type numbers
 884         at once (e.g. "(1,2)=(3,4)="...).
 885
 886         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 887
 888         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 889
 890 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 891
 892         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 893         to process_one_symbol.
 894         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 895         avoid caching a bad endaddr in find_pc_partial_function.
 896
 897 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 898
