   4
   5         * remote-bug.c (bug_ops): Remove spurious newline from docstring.
   6
   7         * config/m68k/tm-monitor.h: Changes to bring this into accordance
   8         with the old tm-m68k-em.h:
   9         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
  10         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
  11         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
  12         Add FIXME regarding GET_LONGJMP_TARGET.
  13
  14         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
  15         * infptrace.c (kill_inferior): Add comments.

  17         detach.
  18         * remote-udi.c (udi_close): Don't error() if QUITTING.
  19
  20 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
  21
  22         * configure.in: Make m68k-coff and aout add monitor support in
  23         addition to the standard serial support.
  24
  25 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  26
  27         * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
  28         index indexNil.
  29
  30 Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  31
  32         * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
  33         * elfread.c (record_minimal_symbol_and_info),
  34         dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
  35
  36 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  37
  38         * i386-stub.c: Add ".text" right before "mem_fault:".
  39
  40         * main.c (baud_rate): Add FIXME comment about printing -1 value.
  41
  42         * remote-utils.c (usage): Fix message to be accurate and conform
  43         more closely to normal conventions.
  44
  45         * remote-utils.c (gr_files_info): Have the exec_bfd test control
  46         whether to show information about exec_bfd, and not control whether
  47         to show information about device and speed.
  48
  49         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
  50         usage message, don't dump core.
  51
  52         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
  53         for variable size array.
  54         (bug_fetch_register, bug_store_register): Rename "value" to
  55         "fpreg_buf" because some compilers don't like variables whose
  56         names are the same as types.
  57         (bug_store_register): Use a cast when converting char * to
  58         unsigned char *.
  59
  60         * symmisc.c (maintenance_print_symbols): Don't refer to the name
  61         of the command in error message (the text was referring to the old
  62         name of the command).
  63
  64         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
  65
  66         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
  67         full details on structure elements without names.  This partially
  68         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
  69         of those changes was accidental.
  70
  71         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
  72         defined, make it an error to specify a single argument which is not
  73         a frame number.
  74
  75         * Makefile.in (version.c), main.c (print_gdb_version): Use
  76         host_alias and target_alias, not host_canonical and
  77         target_canonical, to print configuration.
  78
  79 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  80
  81         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
  82         of builtin_type_long.  It is necessary to get a type which is
  83         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
  84
  85         Fix many sins which will come up in 32 bit x 64 bit GDB, and
  86         various miscellaneous things discovered in the process:
  87         * printcmd.c, defs.h (print_address_numeric): New function.
  88         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
  89         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
  90         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
  91         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
  92         Use it.
  93         * utils.c, defs.h (gdb_print_address): New function.
  94         * expprint (dump_expression), gdbtypes.h: Use it.
  95         * breakpoint.c (describe_other_breakpoints),
  96         symmisc.c (dump_symtab, print_symbol):
  97         Use filtered not unfiltered I/O.
  98         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
  99         just run gdb under a debugger for this (and it had problems with
 100         printing addresses, how to print b->shadow, etc.).
 101         * buildsym.c (make_blockvector), core.c (memory_error),
 102         exec.c (print_section_info), maint.c (print_section_table),
 103         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 104         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 105         Add comments saying code is broken.  Marked with "FIXME-32x64".
 106         * dbxread.c (process_one_symbol), partial-stab.h (default),
 107         remote-vx.c (vx_run_files_info):
 108         Don't cast int being passed to local_hex_string.
 109         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 110         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 111         only being a long.
 112         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 113         and LOC_LOCAL.
 114         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 115         * source.c: Include <sys/types.h> regardless of USG.
 116
 117 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 118
 119         * valops.c (value_assign):  Set `type' after coercing toval.
 120         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 121         Use extract_unsigned_integer to get the address of a reference.
 122
 123 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 124
 125         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 126         AIX can use ? instead of \ for continuation.  Deal with it.
 127
 128         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 129         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 130         the HP compiler in ANSI mode doesn't like.
 131
 132         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 133         based on USG, rather than defining HAVE_SIGSETMASK to an
 134         expression containing defined.  Having a macro used in #if expand
 135         to an expression containing "defined" is undefined according to
 136         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 137         it to.
 138
 139 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 140
 141         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 142         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 143
 144 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 145
 146         * ch-exp.y (match_string_literal):  Allow a zero-length string.
 147         * ch-lang.c (chill_printstr):  Don't print zero-length string funny.
 148
 149 Sat Jan 22 17:08:48 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 150
 151         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 152         passing them to print_387_status.
 153         (print_387_status): Don't subtract top from 7 before using it.
 154         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 155         from 7; the above explains it.
 156
 157 Sat Jan 22 20:25:11 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 158
 159         * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
 160         pointer value when fixing up the frame at the start of a function.
 161
 162 Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)
 163
 164         * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
 165         Sparc from the stack.
 166
 167 Sat Jan 22 08:30:42 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 168
 169         * remote-mips.c (mips_initialize): Clear mips_initializing via
 170         cleanup chain, not directly.
 171
 172         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 173         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 174         munging the timeout due to the limited range of c_cc[VTIME].
 175
 176         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
 177         * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
 178         m3-nat.c (m3_create_inferior): Pass it.
 179         * procfs.c: Remove ptrace function.  It was declared in a way which
 180         conflicted with the prototype in unistd.h on Solaris.
 181
 182 Sat Jan 22 01:37:40 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 183
 184         * sparc-tdep.c (frame_saved_pc):  Get the pc from the saved pc
 185         in the sigcontext if it is a signal trampoline frame.
 186         * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
 187         Define for Solaris2.
 188
 189 Sat Jan 22 00:34:47 1994  Stu Grossman  (grossman at cygnus.com)
 190
 191         * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
 192         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 193         tm-sparc.h so they can be overridden if necessary.
 194
 195 Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)
 196
 197         * lynx-nat.c:  Add Sparc support.
 198         * sparcly-nat.c:  Remove.  It's useless.
 199         * config/sparc/nm-sparclynx.h:  Rewrite.
 200         * config/sparc/sparclynx.mh (NATDEPFILES):  Replace sparcly-nat.o
 201         with lynx-nat.o
 202         * config/sparc/tm-sparclynx.h:  Rewrite.
 203
 204 Fri Jan 21 19:08:48 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 205
 206         * rs6000-pinsn.c: Use the new disassembler in the opcodes
 207         directory.  Old code was discarded, since the new opcode table has
 208         a different format.
 209
 210 Fri Jan 21 14:28:30 1994  Fred Fish  (fnf@cygnus.com)
 211
 212         * Makefile.in (realclean):  Remove info files per make-stds.texi.
 213
 214 Fri Jan 21 12:47:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 215
 216         * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
 217         if N_SO_ADDRESS_MAYBE_MISSING is defined.
 218         * config/sparc/tm-sun4sol2.h: Define it.
 219
 220 Thu Jan 20 15:04:24 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 221
 222         * printcmd.c (print_address_symbolic):  Unconditionally use msymbol
 223         if we did not find a symbol.
 224
 225 Fri Jan 21 08:20:18 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 226
 227         * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
 228         is not defined.
 229
 230         * hppab-nat.c (call_ptrace): Delete redundant function.
 231         (kill_inferior, attach, detach, child_resume): Likewise.
 232         (child_xfer_memory): Likewise.
 233
 234         * hppah-nat.c (call_ptrace): Delete redundant function.
 235         (kill_inferior, attach, detach, child_resume): Likewise.
 236
 237         * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
 238
 239         * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
 240
 241         * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
 242
 243         * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
 244         (CHILD_XFER_MEMORY): Define.
 245         (PT_*): Define so that generic infptrace.c code can be used.
 246
 247 Fri Jan 21 09:23:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 248
 249         * xcoffread.c (xcoff_symfile_read): Make second parameter a
 250         struct section_offsets *, not a (nonexistent) struct section_offset *.
 251
 252         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 253         internal_xcoff_symtab, not an array of one of them.  Change lots of
 254         "main_aux" to "&main_aux" and so on.
 255
 256         * coffread.c, xcoffread.c: Include <coff/internal.h>
 257         before "symfile.h".
 258
 259 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 260
 261         * coffread.c (coff_getfilename): Make it not static.
 262
 263         * xcoffread.c (read_xcoff_symtab): complain() not abort().
 264
 265         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 266         a completely gratuitous difference between xcoffread.c and coffread.c).
 267
 268 Wed Jan 19 15:09:44 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 269
 270         * infrun.c (wait_for_inferior): Don't set frame for
 271         step_resume_breakpoint for IN_SIGTRAMP cases.
 272
 273         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 274         breakpoint.c (bpstat_what): Move step_resume from its own field of
 275         the struct bpstat_what into the main_action.  Make it override
 276         other breakpoints.  This is a conservative change in the sense
 277         that before the step resume breakpoint was a breakpoint.c
 278         breakpoint, hitting the step resume breakpoint overrode even
 279         calling bpstat_stop_status.
 280
 281 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 282
 283         * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
 284         in case execution was stopped in the called function.
 285         * stack.c (print_frame_info, frame_info):  If backtracing through
 286         a call dummy, handle the starting source line number on a line
 287         boundary like backtracing through sigtramp.
 288         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 289         for call dummy frame right.  Remove old test for dummy frame,
 290         it has been unused at least since gdb-3.5.
 291         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 292         of the dummy frame.
 293
 294 Tue Jan 18 16:16:35 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 295
 296         * infcmd.c (signal_command): Accept 0 as legitimate signal number.
 297
 298 Tue Jan 18 14:09:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 299
 300         * infrun.c (signals_info), target.c (target_signal_from_name):
 301         Use ugly casts to avoid enumvar < enumvar or enumvar++.
 302
 303 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 304
 305         * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
 306         * inflow.c (terminal_ours_1): When discussing how to deal with the
 307         tty state, make note of query() as well as readline.
 308
 309         * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
 310         signals for which stop and print are cleared by default.
 311
 312 Mon Jan 17 20:00:51 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 313
 314         * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
 315         reserved fields to hold a stub unwind entry type.  Fix typo.
 316         (stub_unwind_entry): New structure for raw stub unwind entries.
 317         (stub_unwind_types): The types of stubs we may encounter.
 318         (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
 319         * hppa-tdep.c (rp_saved): Use additional information provided
 320         by linker stub unwind descriptors.
 321         (frameless_function_invocation): Likewise.
 322         (frame_chain_valid): Likewise.
 323         * paread.c (compare_unwind_entries): New function for sorting
 324         unwind table entries.
 325         (read_unwind_info): Rewrite to remove dependency on host endianness.
 326         Read in data from the $UNWIND_END$ subspace which contains linker
 327         stub unwind descriptors.  Merge that data into the basic unwind
 328         table.
 329
 330         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 331
 332 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 333
 334         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
 335         from either the symbol name or the auxent.
 336         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
 337         no longer static.
 338

 340
 341         * Makefile.in (ALLPARAM):  Change irix5.h to nm-irix5.h.
 342

 344
 345         * README:  Update notes for alpha port.
 346
 347 Mon Jan 17 11:15:57 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 348
 349         * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
 350         for operation fault, constraint fault, and type fault.
 351

 353
 354         * Makefile.in (init.c): Add comment explaining formatting conventions.
 355
 356         * c-exp.y (parse_number): Assign to temporary between the right
 357         shifts, to work around a bug in the SCO compiler.
 358
 359         * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
 360         Add various files which were added to GDB recently.
 361
 362         * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
 363         within_function.
 364
 365         * Makefile.in: Add mostlyclean target.

 367 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 368
 369         * Version 4.11.4.
 370
 371 Sat Jan 15 18:27:34 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 372
 373         * main.c (show_commands):  Make return type of extern
 374         history_get be HIST_ENTRY, rather than struct _hist_entry.
 375         (The latter loses with the upcoming merged readline.)
 376
 377 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 378
 379         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
 380         const char *, not char *.
 381
 382         * symtab.h (struct symbol): Make section short, not unsigned short.
 383
 384         * symtab.c (lookup_symbol): Add comment about QUIT here.
 385
 386         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 387
 388         * c-exp.y (parse_number): Check for overflow regardless of range
 389         checking.  Fix overflow check to use unsigned LONGEST, not
 390         unsigned int.
 391
 392         * c-exp.y (parse_number): Make it so that integer constants are
 393         builtin_type_long_long if builtin_type_long isn't big enough or if
 394         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 395
 396         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 397         Print our "()" first, then recurse for the target type.
 398
 399 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 400
 401         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 402
 403         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
 404
 405 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 406
 407         * utils.c (request_quit): Re-establish signal handler regardless
 408         of USG.
 409
 410         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 411
 412 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 413
 414         * i960-tdep.c: Include target.h.
 415
 416 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 417
 418         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 419
 420 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 421
 422         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 423         changes (status -> ourstatus; declare status, etc.).
 424         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
 425
 426 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 427
 428         * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
 429
 430 Fri Jan 14 11:49:44 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 431
 432         * remote-mips.c (mips_request, mips_wait): Correct prototypes.
 433
 434 Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 435
 436         * config/i386/xm-linux.h: Define HAVE_TERMIOS.
 437
 438 Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 439
 440         * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.
 441
 442 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 443
 444         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 445         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 446
 447         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 448         writing it.
 449
 450         Add search to target vector (#if 0'd until after 4.12):
 451         * target.h (to_search, target_search): Add.
 452         * gdbcore.h, core.c (generic_search): Add.
 453         * remote.c (remote_search): Add.
 454         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 455         tag.
 456
 457         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 458         is on, call find_pc_function rather than relying just on the minimal
 459         symbols (probably only matters for symbol readers which don't put
 460         statics in the minimal symbols, but changing this strikes me as
 461         not conservative enough).
 462         Initialize name_location in all cases.
 463         If no symbol and no msymbol, don't print anything symbolic.
 464
 465         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 466
 467 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 468
 469         * printcmd.c (print_address_symbolic):  Make it search the
 470         symtabs for variables as well as functions.  Add `set print
 471         fast-symbolic-addr' and default it to fast (the old way).
 472         Print line numbers for data items as well as functions.
 473
 474         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 475         address, if a symbol is found (take two more args pointing to
 476         where to store these results).
 477
 478         * symtab.h (find_addr_symbol):  Add prototype.
 479
 480 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 481
 482         * objfiles.h: Fix comments to reflect the fact that the phrase
 483         "top of stack" always refers to where the pushing and popping takes
 484         place, regardless of whether it is at the highest or lowest address.
 485
 486 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 487
 488         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 489         compiler generated tag names.
 490         * mdebugread.c (parse_type):  Handle cross references to qualified
 491         aggregate types.
 492         * valops.c (value_struct_elt):  Improve error message if the
 493         address of a method is requested from an object instance.
 494         * valops.c (search_struct_method):  Make name_matched non-static
 495         to get it initialized correctly.
 496         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 497         exclude segment register which are not writable on newer SCO versions.
 498
 499 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 500
 501         * go32-xdep.c: Remove unused function uerror.
 502         (sigsetmask): Declare return type.  Declare argument (to match the
 503         way it is called).  Explicitly return 0.
 504
 505 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 506
 507         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 508         partial_symbol):  Shrink the storage sizes of symbols, by making
 509         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 510         enums and small ints to the end of each struct to improve
 511         alignment, and switching the section number from int to unsigned
 512         short.
 513
 514 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 515
 516         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 517         symbol associated with an address.  It does so by exhaustive
 518         search of the symtabs, so it's slow but complete.
 519
 520 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 521
 522         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 523         to [0,0] rather than [0, end of first source file].  This avoids
 524         problems with other parts of GDB looking for linetables in the
 525         _globals_ symtab.  Eliminate variables num_object_files and
 526         first_object_file_end.
 527
 528 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 529
 530         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 531         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 532         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 533         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 534         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 535         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 536         (SETUP_ARBITRARY_FRAME):  Define.
 537
 538 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 539
 540         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 541
 542 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 543
 544         * remote-udi.c (udi_resume): Correct prototype.
 545
 546 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 547
 548         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 549         hppa_frame_find_saved_regs.
 550         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 551         (prologue_inst_adjust_sp): New function.
 552         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 553         (skip_prologue): Completely rewrite to use unwind information.
 554         (hppa_frame_find_saved_regs): Likewise.
 555
 556 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 557
 558         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 559         to convert a signal number with appropriate bounds checking.
 560
 561         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 562
 563 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 564
 565         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 566         print a newline to end the display anyway.
 567
 568         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 569         coprocessor status regs) when popping a frame.  This fixes
 570         float exceptions that occur after calling inferior functions.
 571
 572         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 573         Read and write the fsr (float status register) to/from the child
 574         process along with the float regs.  Remove Peter Schauer's change
 575         of May 24 '93, which has higher overhead and doesn't solve the
 576         real problem (which was that FSR wasn't being set).
 577
 578 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 579
 580         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 581         stack overflow check isn't right after the register stack
 582         adjustment instruction.  Metaware R2.3u compiler moves other
 583         things in front of it.  This fix isn't perfect but is what's
 584         running.
 585
 586 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 587
 588         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 589
 590         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 591         character filenames.
 592         * configure.in: Change accordingly.
 593
 594 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 595
 596         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 597         _filtered io routines from these two files.
 598
 599 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 600
 601         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 602         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 603         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 604         DEC c89.
 605         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 606
 607 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 608
 609         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 610         printing to gdb_stderr.
 611
 612         * remote-udi.c (udi_kill): Don't close the connection, just set
 613         inferior_pid to zero.
 614         (udi_mourn): Call remove_breakpoints.
 615
 616         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 617
 618         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 619
 620 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 621
 622         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 623
 624         * remote-bug.c: At the start of each section, reset srec_frame
 625         back to 160.
 626
 627         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 628         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 629         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 630         code which looks for those two waitkinds.  Use switch statement.
 631         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 632         CHILD_SPECIAL_WAITSTATUS.
 633
 634         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 635         * Move target_signal_from_host, target_signal_to_host, and
 636         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 637         * target.c: Include "wait.h" and <signal.h>.
 638         * target.h, infrun.c (proceed), proceed callers: Pass new code
 639         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 640         enums being treated as unsigned and is cleaner.
 641         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 642         TARGET_SIGNAL_0.
 643         * infcmd.c (signal_command), infrun.c (signals_info):
 644         Don't allow user to specify numeric equivalent of
 645         TARGET_SIGNAL_DEFAULT.
 646
 647 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 648
 649         * config/alpha/alpha-netware.mt:  New target support for Alpha
 650         running Netware.
 651         * configure.in:  Add alpha-*-netware* target.
 652
 653 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 654
 655         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 656
 657 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 658
 659         * target.h: Add enum target_waitkind, enum target_signal, and
 660         struct target_waitstatus.  Change status argument to target_wait to
 661         be struct target_waitstatus * instead of int *.
 662         * target.h, infrun.c, all targets: Change type of signal arguments
 663         to resume(), proceed(), and target_resume() from int to enum
 664         target_signal.
 665         * All targets (*_wait, *_resume): Change accordingly.
 666         * infcmd.c (program_info, signal_command), throughout infrun.c,
 667         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 668         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 669         signal code stuff right with the new signals would be non-trivial).
