   1 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   2
   3         * printcmd.c (decode_format): Don't blithely set the size for
   4         an address to 'w'.  Make it 'g' or 'h', depending on TARGET_PTR_BIT.
   5
   6         * defs.h: Just typedef CORE_ADDR to bfd_vma.  Include bfd.h.
   7         If BFD64, make a LONGEST a BFD_HOST_64_BIT.
   8         * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
   9         always just check against INT_MIN and INT_MAX (this also fixes things
  10         if sizeof (long) > sizeof (int), e.g. Alpha).
  11         * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
  12         Don't define LONGEST or BUILTIN_TYPE_LONGEST.
  13         * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
  14         BUILTIN_TYPE_UNSIGNED_LONGEST.
  15         * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
  16         longest_int and longest_unsigned_int.
  17         * value.h (struct value): Just align to LONGEST, rather than worrying
  18         about CC_HAS_LONG_LONG.
  19         * valarith.c (value_binop): Figure out type ourself based on
  20         sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST.  The
  21         point is that we don't depend on CC_HAS_LONG_LONG anymore.
  22         * valprint.c (val_print_type_code_int): Just call
  23         extract_unsigned_integer directly, rather than going through
  24         unpack_long.
  25         * printcmd.c (decode_format): Remove code which would sometimes
  26         change 'g' size to 'w' for integers.  print_scalar_formatted handles
  27         printing huge integers well enough, thank you.
  28
  29         * command.c (add_set_cmd, no_just_help_class_command): Change
  30         to make this the sfunc, not cfunc, since that is how we call it.
  31         * command.h: Comment difference between sfunc and cfunc.
  32         * demangle.c (set_demangling_command): Add third arg since that
  33         is how it is called.
  34         (_initialize_demangler): Use sfunc, not cfunc, for
  35         set_demangling_command, since that is how it is called.
  36         Remove show_demangling_command; it has no effect.
  37
  38         * command.c (shell_escape): Report errors correctly (with error
  39         message from strerror).
  40
  41 Wed Feb  2 14:35:41 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  42
  43         * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
  44         x_scnlen.l rather than x_scnlen to match corresponding change in
  45         coff/internal.h.
  46
  47 Wed Feb  2 11:16:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  48
  49         * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
  50         Change comments regarding TYPE_CODE_BOOL.
  51         * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
  52         regardless of the language.
  53         (value_true): Just call value_logical_not regardless of language.
  54         * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
  55         Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
  56         * language.h: Improve comment for la_builtin_type_vector.
  57         * m2-lang.c (_initialize_m2_language): Don't add any fields to
  58         builtin_type_m2_bool.
  59
  60 Tue Feb  1 17:13:32 1994  Kevin Buettner (kev@cujo.geg.mot.com)
  61
  62         * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
  63         Define IN_SIGTRAMP and backtrace correctly through signal handlers.
  64
  65 Tue Feb  1 22:13:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  66
  67         * procfs.c (wait_fd):  Handle EINTR error return from PIOCWSTOP ioctl
  68         by restarting the ioctl.
  69
  70 Tue Feb  1 16:16:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  71
  72         * target.h (target_wait): Add comment about calling
  73         return_to_top_level.
  74
  75 Tue Feb  1 12:21:00 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
  76
  77         * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
  78         additional arguments.
  79         * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
  80
  81 Mon Jan 31 16:10:41 1994  Stu Grossman  (grossman at cygnus.com)
  82
  83         * sparc-stub.c:  Remove unnecessary #include of memory.h.
  84
  85 Mon Jan 31 12:12:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  86
  87         * mips-tdep.c: Remove code which sets saved_regs from
  88         init_extra_frame_info and put it in new function mips_find_saved_regs.
  89         (READ_FRAME_REG): Remove macro and replace uses with the expansion.
  90         * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
  91         check if it is NULL and call mips_find_saved_regs if so.
  92
  93         * remote-mips.c: Use unfiltered, not filtered, output most places.
  94
  95         * blockframe.c (get_prev_frame_info): Detect and stop an infinite
  96         backtrace.  Revise comments.
  97
  98 Mon Jan 31 09:40:33 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  99
 100         * mdebugread.c (parse_procedure):  Remove _sigtramp kludges for
 101         alpha and irix. The _sigtramp case has to be handled properly
 102         in the tdep files if we have no ecoff debugging info.
 103         * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
 104         mips-tdep.c (mips_frame_saved_pc):  Handle signal handler frames
 105         without PC_REGNUM kludge.
 106         * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
 107         Clean up handling of mips sigtramp frames, improve comments.
 108
 109 Sat Jan 29 23:25:57 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 110
 111         * paread.c (read_unwind_info): Fix typo.
 112
 113         * paread.c (pa_symtab_read): Update the "check_strange_names"
 114         filter to match GCC's current output.  Filter out section symbols
 115         (which the HP linker sometimes puts in the wrong place).
 116
 117 Sat Jan 29 07:44:59 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 118
 119         * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
 120
 121         * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
 122
 123         * Makefile.in: Remove all references to sparcly-nat.c.
 124
 125         * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
 126         remote-sim.h directly, rather than via $(remote_utils_h).  This avoids
 127         duplicating serial.h and target.h.
 128
 129         * Makefile.in: Don't set M_INSTALL and M_UNINSTALL.  These variables
 130         are not used anywhere (a 5 Oct 1993 change removed the uses).
 131
 132         * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
 133         * config/m68k/es1800.mt: Add comment.
 134         * remote-es.c: Extensive changes to update to current conventions.
 135
 136         * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
 137         If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
 138         to achieve the desired timeout.
 139         * serial.h (serial_t): Add field timeout_remaining.
 140
 141 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 142
 143         * c-exp.y (yylex): Reenable nested type code.
 144
 145 Fri Jan 28 15:40:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 146
 147         * a29k-tdep.c (examine_tag): Add comment regarding argcount.
 148
 149         * remote-mips.c (mips_ops): Fix docstring.
 150
 151         * remote-bug.c (bug_ops): Remove spurious newline from docstring.
 152
 153         * config/m68k/tm-monitor.h: Changes to bring this into accordance
 154         with the old tm-m68k-em.h:
 155         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
 156         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
 157         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
 158         Add FIXME regarding GET_LONGJMP_TARGET.
 159
 160         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
 161         * infptrace.c (kill_inferior): Add comments.
 162         * main.c (quit_command): Call target_close after we kill or
 163         detach.
 164         * remote-udi.c (udi_close): Don't error() if QUITTING.
 165
 166 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
 167
 168         * configure.in: Make m68k-coff and aout add monitor support in
 169         addition to the standard serial support.
 170
 171 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 172
 173         * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
 174         index indexNil.
 175
 176 Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 177
 178         * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
 179         * elfread.c (record_minimal_symbol_and_info),
 180         dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
 181
 182 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 183
 184         * i386-stub.c: Add ".text" right before "mem_fault:".
 185
 186         * main.c (baud_rate): Add FIXME comment about printing -1 value.
 187
 188         * remote-utils.c (usage): Fix message to be accurate and conform
 189         more closely to normal conventions.
 190
 191         * remote-utils.c (gr_files_info): Have the exec_bfd test control
 192         whether to show information about exec_bfd, and not control whether
 193         to show information about device and speed.
 194
 195         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
 196         usage message, don't dump core.
 197
 198         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
 199         for variable size array.
 200         (bug_fetch_register, bug_store_register): Rename "value" to
 201         "fpreg_buf" because some compilers don't like variables whose
 202         names are the same as types.
 203         (bug_store_register): Use a cast when converting char * to
 204         unsigned char *.
 205
 206         * symmisc.c (maintenance_print_symbols): Don't refer to the name
 207         of the command in error message (the text was referring to the old
 208         name of the command).
 209
 210         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
 211
 212         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
 213         full details on structure elements without names.  This partially
 214         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
 215         of those changes was accidental.
 216
 217         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
 218         defined, make it an error to specify a single argument which is not
 219         a frame number.
 220
 221         * Makefile.in (version.c), main.c (print_gdb_version): Use
 222         host_alias and target_alias, not host_canonical and
 223         target_canonical, to print configuration.
 224
 225 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 226
 227         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
 228         of builtin_type_long.  It is necessary to get a type which is
 229         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
 230
 231         Fix many sins which will come up in 32 bit x 64 bit GDB, and
 232         various miscellaneous things discovered in the process:
 233         * printcmd.c, defs.h (print_address_numeric): New function.
 234         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
 235         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
 236         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
 237         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
 238         Use it.
 239         * utils.c, defs.h (gdb_print_address): New function.
 240         * expprint (dump_expression), gdbtypes.h: Use it.
 241         * breakpoint.c (describe_other_breakpoints),
 242         symmisc.c (dump_symtab, print_symbol):
 243         Use filtered not unfiltered I/O.
 244         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
 245         just run gdb under a debugger for this (and it had problems with
 246         printing addresses, how to print b->shadow, etc.).
 247         * buildsym.c (make_blockvector), core.c (memory_error),
 248         exec.c (print_section_info), maint.c (print_section_table),
 249         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 250         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 251         Add comments saying code is broken.  Marked with "FIXME-32x64".
 252         * dbxread.c (process_one_symbol), partial-stab.h (default),
 253         remote-vx.c (vx_run_files_info):
 254         Don't cast int being passed to local_hex_string.
 255         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 256         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 257         only being a long.
 258         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 259         and LOC_LOCAL.
 260         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 261         * source.c: Include <sys/types.h> regardless of USG.
 262
 263 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 264
 265         * valops.c (value_assign):  Set `type' after coercing toval.
 266         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 267         Use extract_unsigned_integer to get the address of a reference.
 268
 269 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 270
 271         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 272         AIX can use ? instead of \ for continuation.  Deal with it.
 273
 274         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 275         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 276         the HP compiler in ANSI mode doesn't like.
 277
 278         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 279         based on USG, rather than defining HAVE_SIGSETMASK to an
 280         expression containing defined.  Having a macro used in #if expand
 281         to an expression containing "defined" is undefined according to
 282         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 283         it to.
 284
 285 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 286
 287         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 288         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 289
 290 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 291
 292         * ch-exp.y (match_string_literal):  Allow a zero-length string.
 293         * ch-lang.c (chill_printstr):  Don't print zero-length string funny.
 294
 295 Sat Jan 22 17:08:48 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 296
 297         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 298         passing them to print_387_status.
 299         (print_387_status): Don't subtract top from 7 before using it.
 300         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 301         from 7; the above explains it.
 302
 303 Sat Jan 22 20:25:11 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 304
 305         * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
 306         pointer value when fixing up the frame at the start of a function.
 307
 308 Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)
 309
 310         * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
 311         Sparc from the stack.
 312
 313 Sat Jan 22 08:30:42 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 314
 315         * remote-mips.c (mips_initialize): Clear mips_initializing via
 316         cleanup chain, not directly.
 317
 318         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 319         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 320         munging the timeout due to the limited range of c_cc[VTIME].
 321
 322         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.

 324         m3-nat.c (m3_create_inferior): Pass it.

 336
 337         * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
 338         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 339         tm-sparc.h so they can be overridden if necessary.
 340
 341 Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)
 342
 343         * lynx-nat.c:  Add Sparc support.

 394
 395         * xcoffread.c (xcoff_symfile_read): Make second parameter a
 396         struct section_offsets *, not a (nonexistent) struct section_offset *.
 397
 398         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 399         internal_xcoff_symtab, not an array of one of them.  Change lots of
 400         "main_aux" to "&main_aux" and so on.
 401
 402         * coffread.c, xcoffread.c: Include <coff/internal.h>
 403         before "symfile.h".
 404
 405 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 406
 407         * coffread.c (coff_getfilename): Make it not static.
 408
 409         * xcoffread.c (read_xcoff_symtab): complain() not abort().
 410
 411         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 412         a completely gratuitous difference between xcoffread.c and coffread.c).
 413

 418
 419         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 420         breakpoint.c (bpstat_what): Move step_resume from its own field of
 421         the struct bpstat_what into the main_action.  Make it override
 422         other breakpoints.  This is a conservative change in the sense
 423         that before the step resume breakpoint was a breakpoint.c
 424         breakpoint, hitting the step resume breakpoint overrode even
 425         calling bpstat_stop_status.
 426
 427 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 428

 432         a call dummy, handle the starting source line number on a line
 433         boundary like backtracing through sigtramp.
 434         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 435         for call dummy frame right.  Remove old test for dummy frame,
 436         it has been unused at least since gdb-3.5.
 437         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 438         of the dummy frame.

 469         * paread.c (compare_unwind_entries): New function for sorting
 470         unwind table entries.
 471         (read_unwind_info): Rewrite to remove dependency on host endianness.
 472         Read in data from the $UNWIND_END$ subspace which contains linker
 473         stub unwind descriptors.  Merge that data into the basic unwind
 474         table.
 475
 476         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 477
 478 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 479
 480         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name

 482         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
 483         no longer static.

 506         Add various files which were added to GDB recently.

 518
 519         * main.c (show_commands):  Make return type of extern
 520         history_get be HIST_ENTRY, rather than struct _hist_entry.
 521         (The latter loses with the upcoming merged readline.)

 524
 525         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring

 530         * symtab.c (lookup_symbol): Add comment about QUIT here.
 531
 532         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 533
 534         * c-exp.y (parse_number): Check for overflow regardless of range
 535         checking.  Fix overflow check to use unsigned LONGEST, not
 536         unsigned int.
 537
 538         * c-exp.y (parse_number): Make it so that integer constants are
 539         builtin_type_long_long if builtin_type_long isn't big enough or if
 540         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 541
 542         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 543         Print our "()" first, then recurse for the target type.
 544
 545 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 546
 547         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.

 589
 590         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 591         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.

 599         * remote.c (remote_search): Add.
 600         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 601         tag.
 602
 603         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 604         is on, call find_pc_function rather than relying just on the minimal
 605         symbols (probably only matters for symbol readers which don't put
 606         statics in the minimal symbols, but changing this strikes me as
 607         not conservative enough).
 608         Initialize name_location in all cases.
 609         If no symbol and no msymbol, don't print anything symbolic.
 610
 611         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 612
 613 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 614
 615         * printcmd.c (print_address_symbolic):  Make it search the
 616         symtabs for variables as well as functions.  Add `set print
 617         fast-symbolic-addr' and default it to fast (the old way).
 618         Print line numbers for data items as well as functions.
 619
 620         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 621         address, if a symbol is found (take two more args pointing to
 622         where to store these results).
 623
 624         * symtab.h (find_addr_symbol):  Add prototype.
 625
 626 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 627
 628         * objfiles.h: Fix comments to reflect the fact that the phrase
 629         "top of stack" always refers to where the pushing and popping takes
 630         place, regardless of whether it is at the highest or lowest address.
 631

 637         aggregate types.
 638         * valops.c (value_struct_elt):  Improve error message if the
 639         address of a method is requested from an object instance.
 640         * valops.c (search_struct_method):  Make name_matched non-static
 641         to get it initialized correctly.
 642         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 643         exclude segment register which are not writable on newer SCO versions.
 644
 645 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 646
 647         * go32-xdep.c: Remove unused function uerror.
 648         (sigsetmask): Declare return type.  Declare argument (to match the
 649         way it is called).  Explicitly return 0.
 650
 651 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 652
 653         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 654         partial_symbol):  Shrink the storage sizes of symbols, by making
 655         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 656         enums and small ints to the end of each struct to improve
 657         alignment, and switching the section number from int to unsigned
 658         short.
 659
 660 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 661
 662         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 663         symbol associated with an address.  It does so by exhaustive
 664         search of the symtabs, so it's slow but complete.
 665
 666 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 667
 668         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 669         to [0,0] rather than [0, end of first source file].  This avoids
 670         problems with other parts of GDB looking for linetables in the
 671         _globals_ symtab.  Eliminate variables num_object_files and
 672         first_object_file_end.

 674 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 675
 676         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 677         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 678         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 679         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 680         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 681         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 682         (SETUP_ARBITRARY_FRAME):  Define.
 683
 684 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 685
 686         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 687
 688 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 689
 690         * remote-udi.c (udi_resume): Correct prototype.
 691
 692 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 693
 694         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 695         hppa_frame_find_saved_regs.
 696         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 697         (prologue_inst_adjust_sp): New function.
 698         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 699         (skip_prologue): Completely rewrite to use unwind information.
 700         (hppa_frame_find_saved_regs): Likewise.
 701
 702 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 703
 704         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 705         to convert a signal number with appropriate bounds checking.
 706
 707         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 708
 709 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 710
 711         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 712         print a newline to end the display anyway.
 713
 714         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 715         coprocessor status regs) when popping a frame.  This fixes
 716         float exceptions that occur after calling inferior functions.
 717
 718         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 719         Read and write the fsr (float status register) to/from the child
 720         process along with the float regs.  Remove Peter Schauer's change
 721         of May 24 '93, which has higher overhead and doesn't solve the
 722         real problem (which was that FSR wasn't being set).
 723
 724 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 725
 726         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 727         stack overflow check isn't right after the register stack
 728         adjustment instruction.  Metaware R2.3u compiler moves other
 729         things in front of it.  This fix isn't perfect but is what's
 730         running.
 731
 732 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 733
 734         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 735
 736         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 737         character filenames.
 738         * configure.in: Change accordingly.
 739
 740 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)

 743         _filtered io routines from these two files.
 744

 748         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 749         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 750         DEC c89.
 751         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 752
 753 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 754
 755         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 756         printing to gdb_stderr.
 757
 758         * remote-udi.c (udi_kill): Don't close the connection, just set
 759         inferior_pid to zero.
 760         (udi_mourn): Call remove_breakpoints.
 761
 762         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 763
 764         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 765
 766 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 767
 768         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 769
 770         * remote-bug.c: At the start of each section, reset srec_frame
 771         back to 160.
 772
 773         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 774         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 775         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 776         code which looks for those two waitkinds.  Use switch statement.
 777         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 778         CHILD_SPECIAL_WAITSTATUS.
 779
 780         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 781         * Move target_signal_from_host, target_signal_to_host, and
 782         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 783         * target.c: Include "wait.h" and <signal.h>.
 784         * target.h, infrun.c (proceed), proceed callers: Pass new code
 785         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 786         enums being treated as unsigned and is cleaner.
 787         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 788         TARGET_SIGNAL_0.
 789         * infcmd.c (signal_command), infrun.c (signals_info):
 790         Don't allow user to specify numeric equivalent of
 791         TARGET_SIGNAL_DEFAULT.
 792
 793 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)

 795         * config/alpha/alpha-netware.mt:  New target support for Alpha
 796         running Netware.
 797         * configure.in:  Add alpha-*-netware* target.

 799 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 800
 801         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 802
 803 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 804
 805         * target.h: Add enum target_waitkind, enum target_signal, and
 806         struct target_waitstatus.  Change status argument to target_wait to
 807         be struct target_waitstatus * instead of int *.
 808         * target.h, infrun.c, all targets: Change type of signal arguments
 809         to resume(), proceed(), and target_resume() from int to enum
 810         target_signal.
 811         * All targets (*_wait, *_resume): Change accordingly.
 812         * infcmd.c (program_info, signal_command), throughout infrun.c,
 813         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 814         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 815         signal code stuff right with the new signals would be non-trivial).
 816         * inferior.h (stop_signal): Make it enum target_signal not int.
 817         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 818         target_signal_from_name): New functions.
 819         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 820         store_waitstatus): New functions.
 821         * procfs.c (procfs_notice_signals): Use them.
 822         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 823         print_fault.
 824         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 825
 826         * objfiles.c (build_objfile_section_table): Don't abort() if
 827         objfile->sections is already set.
 828
 829         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 830         to match recent change to exec.c.
 831
 832         * Version 4.11.3.
 833
 834         * main.c (print_gdb_version): Change year to 1994.
 835
 836         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 837         * Makefile.in (NONSRC): Add ChangeLog-93.

 839 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 840
 841         * stabsread.c (read_type): Allow defining several type numbers
 842         at once (e.g. "(1,2)=(3,4)="...).
 843
 844         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 845
 846         * breakpoint.c (frame_in_dummy): Check PC as well as frame.

 849
 850         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 851         to process_one_symbol.
 852         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 853         avoid caching a bad endaddr in find_pc_partial_function.
 854
 855 Sun Jan  2 21:41:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 856
