   1 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   2
   3         * i386-stub.c: Add ".text" right before "mem_fault:".
   4
   5         * main.c (baud_rate): Add FIXME comment about printing -1 value.
   6
   7         * remote-utils.c (usage): Fix message to be accurate and conform
   8         more closely to normal conventions.
   9
  10         * remote-utils.c (gr_files_info): Have the exec_bfd test control
  11         whether to show information about exec_bfd, and not control whether
  12         to show information about device and speed.
  13
  14         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
  15         usage message, don't dump core.
  16
  17         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
  18         for variable size array.
  19         (bug_fetch_register, bug_store_register): Rename "value" to
  20         "fpreg_buf" because some compilers don't like variables whose
  21         names are the same as types.
  22         (bug_store_register): Use a cast when converting char * to
  23         unsigned char *.
  24
  25         * symmisc.c (maintenance_print_symbols): Don't refer to the name
  26         of the command in error message (the text was referring to the old
  27         name of the command).
  28
  29         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
  30
  31         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
  32         full details on structure elements without names.  This partially
  33         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
  34         of those changes was accidental.
  35
  36         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
  37         defined, make it an error to specify a single argument which is not
  38         a frame number.
  39
  40         * Makefile.in (version.c), main.c (print_gdb_version): Use
  41         host_alias and target_alias, not host_canonical and
  42         target_canonical, to print configuration.
  43
  44 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  45
  46         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
  47         of builtin_type_long.  It is necessary to get a type which is
  48         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
  49
  50         Fix many sins which will come up in 32 bit x 64 bit GDB, and
  51         various miscellaneous things discovered in the process:
  52         * printcmd.c, defs.h (print_address_numeric): New function.
  53         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
  54         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
  55         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
  56         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
  57         Use it.
  58         * utils.c, defs.h (gdb_print_address): New function.
  59         * expprint (dump_expression), gdbtypes.h: Use it.
  60         * breakpoint.c (describe_other_breakpoints),
  61         symmisc.c (dump_symtab, print_symbol):
  62         Use filtered not unfiltered I/O.
  63         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
  64         just run gdb under a debugger for this (and it had problems with
  65         printing addresses, how to print b->shadow, etc.).
  66         * buildsym.c (make_blockvector), core.c (memory_error),
  67         exec.c (print_section_info), maint.c (print_section_table),
  68         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
  69         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
  70         Add comments saying code is broken.  Marked with "FIXME-32x64".
  71         * dbxread.c (process_one_symbol), partial-stab.h (default),
  72         remote-vx.c (vx_run_files_info):
  73         Don't cast int being passed to local_hex_string.
  74         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
  75         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
  76         only being a long.
  77         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
  78         and LOC_LOCAL.
  79         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
  80         * source.c: Include <sys/types.h> regardless of USG.
  81
  82 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  83
  84         * valops.c (value_assign):  Set `type' after coercing toval.
  85         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
  86         Use extract_unsigned_integer to get the address of a reference.
  87
  88 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  89
  90         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
  91         AIX can use ? instead of \ for continuation.  Deal with it.
  92
  93         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
  94         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
  95         the HP compiler in ANSI mode doesn't like.
  96
  97         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
  98         based on USG, rather than defining HAVE_SIGSETMASK to an
  99         expression containing defined.  Having a macro used in #if expand
 100         to an expression containing "defined" is undefined according to
 101         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 102         it to.
 103
 104 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 105
 106         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 107         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 108
 109 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 110
 111         * ch-exp.y (match_string_literal):  Allow a zero-length string.
 112         * ch-lang.c (chill_printstr):  Don't print zero-length string funny.
 113
 114 Sat Jan 22 17:08:48 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 115
 116         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 117         passing them to print_387_status.
 118         (print_387_status): Don't subtract top from 7 before using it.
 119         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 120         from 7; the above explains it.
 121
 122 Sat Jan 22 20:25:11 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 123
 124         * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
 125         pointer value when fixing up the frame at the start of a function.
 126
 127 Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)
 128
 129         * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
 130         Sparc from the stack.
 131
 132 Sat Jan 22 08:30:42 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 133
 134         * remote-mips.c (mips_initialize): Clear mips_initializing via
 135         cleanup chain, not directly.
 136
 137         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 138         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 139         munging the timeout due to the limited range of c_cc[VTIME].
 140
 141         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
 142         * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
 143         m3-nat.c (m3_create_inferior): Pass it.
 144         * procfs.c: Remove ptrace function.  It was declared in a way which
 145         conflicted with the prototype in unistd.h on Solaris.
 146
 147 Sat Jan 22 01:37:40 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 148
 149         * sparc-tdep.c (frame_saved_pc):  Get the pc from the saved pc
 150         in the sigcontext if it is a signal trampoline frame.
 151         * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
 152         Define for Solaris2.
 153
 154 Sat Jan 22 00:34:47 1994  Stu Grossman  (grossman at cygnus.com)
 155
 156         * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
 157         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 158         tm-sparc.h so they can be overridden if necessary.
 159
 160 Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)
 161
 162         * lynx-nat.c:  Add Sparc support.
 163         * sparcly-nat.c:  Remove.  It's useless.
 164         * config/sparc/nm-sparclynx.h:  Rewrite.
 165         * config/sparc/sparclynx.mh (NATDEPFILES):  Replace sparcly-nat.o
 166         with lynx-nat.o
 167         * config/sparc/tm-sparclynx.h:  Rewrite.
 168
 169 Fri Jan 21 19:08:48 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 170
 171         * rs6000-pinsn.c: Use the new disassembler in the opcodes
 172         directory.  Old code was discarded, since the new opcode table has
 173         a different format.
 174
 175 Fri Jan 21 14:28:30 1994  Fred Fish  (fnf@cygnus.com)
 176
 177         * Makefile.in (realclean):  Remove info files per make-stds.texi.
 178
 179 Fri Jan 21 12:47:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 180
 181         * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
 182         if N_SO_ADDRESS_MAYBE_MISSING is defined.
 183         * config/sparc/tm-sun4sol2.h: Define it.
 184
 185 Thu Jan 20 15:04:24 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)

 187         * printcmd.c (print_address_symbolic):  Unconditionally use msymbol
 188         if we did not find a symbol.
 189
 190 Fri Jan 21 08:20:18 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 191
 192         * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
 193         is not defined.
 194
 195         * hppab-nat.c (call_ptrace): Delete redundant function.
 196         (kill_inferior, attach, detach, child_resume): Likewise.
 197         (child_xfer_memory): Likewise.
 198
 199         * hppah-nat.c (call_ptrace): Delete redundant function.
 200         (kill_inferior, attach, detach, child_resume): Likewise.
 201
 202         * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
 203
 204         * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
 205
 206         * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
 207
 208         * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
 209         (CHILD_XFER_MEMORY): Define.
 210         (PT_*): Define so that generic infptrace.c code can be used.
 211
 212 Fri Jan 21 09:23:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 213
 214         * xcoffread.c (xcoff_symfile_read): Make second parameter a
 215         struct section_offsets *, not a (nonexistent) struct section_offset *.
 216
 217         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 218         internal_xcoff_symtab, not an array of one of them.  Change lots of
 219         "main_aux" to "&main_aux" and so on.
 220
 221         * coffread.c, xcoffread.c: Include <coff/internal.h>
 222         before "symfile.h".
 223
 224 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 225
 226         * coffread.c (coff_getfilename): Make it not static.
 227
 228         * xcoffread.c (read_xcoff_symtab): complain() not abort().
 229
 230         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 231         a completely gratuitous difference between xcoffread.c and coffread.c).
 232
 233 Wed Jan 19 15:09:44 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 234
 235         * infrun.c (wait_for_inferior): Don't set frame for
 236         step_resume_breakpoint for IN_SIGTRAMP cases.
 237
 238         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 239         breakpoint.c (bpstat_what): Move step_resume from its own field of
 240         the struct bpstat_what into the main_action.  Make it override
 241         other breakpoints.  This is a conservative change in the sense
 242         that before the step resume breakpoint was a breakpoint.c
 243         breakpoint, hitting the step resume breakpoint overrode even
 244         calling bpstat_stop_status.
 245
 246 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 247
 248         * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
 249         in case execution was stopped in the called function.
 250         * stack.c (print_frame_info, frame_info):  If backtracing through
 251         a call dummy, handle the starting source line number on a line
 252         boundary like backtracing through sigtramp.
 253         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 254         for call dummy frame right.  Remove old test for dummy frame,
 255         it has been unused at least since gdb-3.5.
 256         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 257         of the dummy frame.
 258
 259 Tue Jan 18 16:16:35 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 260
 261         * infcmd.c (signal_command): Accept 0 as legitimate signal number.
 262
 263 Tue Jan 18 14:09:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 264
 265         * infrun.c (signals_info), target.c (target_signal_from_name):
 266         Use ugly casts to avoid enumvar < enumvar or enumvar++.
 267
 268 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 269
 270         * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
 271         * inflow.c (terminal_ours_1): When discussing how to deal with the
 272         tty state, make note of query() as well as readline.
 273
 274         * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
 275         signals for which stop and print are cleared by default.
 276
 277 Mon Jan 17 20:00:51 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 278
 279         * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
 280         reserved fields to hold a stub unwind entry type.  Fix typo.
 281         (stub_unwind_entry): New structure for raw stub unwind entries.
 282         (stub_unwind_types): The types of stubs we may encounter.
 283         (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
 284         * hppa-tdep.c (rp_saved): Use additional information provided
 285         by linker stub unwind descriptors.
 286         (frameless_function_invocation): Likewise.
 287         (frame_chain_valid): Likewise.
 288         * paread.c (compare_unwind_entries): New function for sorting
 289         unwind table entries.
 290         (read_unwind_info): Rewrite to remove dependency on host endianness.
 291         Read in data from the $UNWIND_END$ subspace which contains linker
 292         stub unwind descriptors.  Merge that data into the basic unwind
 293         table.
 294
 295         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 296
 297 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 298
 299         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
 300         from either the symbol name or the auxent.
 301         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
 302         no longer static.

 318
 319         * Makefile.in (init.c): Add comment explaining formatting conventions.
 320
 321         * c-exp.y (parse_number): Assign to temporary between the right
 322         shifts, to work around a bug in the SCO compiler.
 323
 324         * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
 325         Add various files which were added to GDB recently.
 326

 328         within_function.
 329

 336 Sat Jan 15 18:27:34 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 337
 338         * main.c (show_commands):  Make return type of extern
 339         history_get be HIST_ENTRY, rather than struct _hist_entry.
 340         (The latter loses with the upcoming merged readline.)
 341
 342 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 343
 344         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
 345         const char *, not char *.
 346
 347         * symtab.h (struct symbol): Make section short, not unsigned short.
 348
 349         * symtab.c (lookup_symbol): Add comment about QUIT here.
 350
 351         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 352
 353         * c-exp.y (parse_number): Check for overflow regardless of range
 354         checking.  Fix overflow check to use unsigned LONGEST, not
 355         unsigned int.
 356
 357         * c-exp.y (parse_number): Make it so that integer constants are
 358         builtin_type_long_long if builtin_type_long isn't big enough or if
 359         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 360
 361         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 362         Print our "()" first, then recurse for the target type.
 363
 364 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 365
 366         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 367
 368         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
 369
 370 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 371
 372         * utils.c (request_quit): Re-establish signal handler regardless
 373         of USG.
 374
 375         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 376
 377 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 378
 379         * i960-tdep.c: Include target.h.
 380
 381 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 382
 383         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 384
 385 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 386
 387         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 388         changes (status -> ourstatus; declare status, etc.).
 389         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
 390
 391 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 392
 393         * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
 394
 395 Fri Jan 14 11:49:44 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 396
 397         * remote-mips.c (mips_request, mips_wait): Correct prototypes.
 398
 399 Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 400
 401         * config/i386/xm-linux.h: Define HAVE_TERMIOS.
 402
 403 Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 404
 405         * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.
 406
 407 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 408
 409         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 410         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 411
 412         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 413         writing it.
 414
 415         Add search to target vector (#if 0'd until after 4.12):
 416         * target.h (to_search, target_search): Add.
 417         * gdbcore.h, core.c (generic_search): Add.
 418         * remote.c (remote_search): Add.
 419         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 420         tag.
 421
 422         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 423         is on, call find_pc_function rather than relying just on the minimal
 424         symbols (probably only matters for symbol readers which don't put
 425         statics in the minimal symbols, but changing this strikes me as
 426         not conservative enough).
 427         Initialize name_location in all cases.
 428         If no symbol and no msymbol, don't print anything symbolic.
 429
 430         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 431
 432 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 433
 434         * printcmd.c (print_address_symbolic):  Make it search the
 435         symtabs for variables as well as functions.  Add `set print
 436         fast-symbolic-addr' and default it to fast (the old way).
 437         Print line numbers for data items as well as functions.
 438
 439         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 440         address, if a symbol is found (take two more args pointing to
 441         where to store these results).
 442
 443         * symtab.h (find_addr_symbol):  Add prototype.
 444
 445 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 446
 447         * objfiles.h: Fix comments to reflect the fact that the phrase
 448         "top of stack" always refers to where the pushing and popping takes
 449         place, regardless of whether it is at the highest or lowest address.
 450
 451 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 452
 453         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 454         compiler generated tag names.
 455         * mdebugread.c (parse_type):  Handle cross references to qualified
 456         aggregate types.
 457         * valops.c (value_struct_elt):  Improve error message if the
 458         address of a method is requested from an object instance.
 459         * valops.c (search_struct_method):  Make name_matched non-static
 460         to get it initialized correctly.
 461         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 462         exclude segment register which are not writable on newer SCO versions.
 463
 464 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 465
 466         * go32-xdep.c: Remove unused function uerror.
 467         (sigsetmask): Declare return type.  Declare argument (to match the
 468         way it is called).  Explicitly return 0.
 469
 470 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 471
 472         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 473         partial_symbol):  Shrink the storage sizes of symbols, by making
 474         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 475         enums and small ints to the end of each struct to improve
 476         alignment, and switching the section number from int to unsigned
 477         short.
 478
 479 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 480
 481         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 482         symbol associated with an address.  It does so by exhaustive
 483         search of the symtabs, so it's slow but complete.
 484
 485 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 486
 487         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 488         to [0,0] rather than [0, end of first source file].  This avoids
 489         problems with other parts of GDB looking for linetables in the
 490         _globals_ symtab.  Eliminate variables num_object_files and
 491         first_object_file_end.
 492
 493 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 494
 495         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 496         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 497         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 498         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 499         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 500         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 501         (SETUP_ARBITRARY_FRAME):  Define.
 502
 503 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 504
 505         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 506
 507 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 508
 509         * remote-udi.c (udi_resume): Correct prototype.
 510
 511 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 512
 513         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 514         hppa_frame_find_saved_regs.
 515         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 516         (prologue_inst_adjust_sp): New function.
 517         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 518         (skip_prologue): Completely rewrite to use unwind information.
 519         (hppa_frame_find_saved_regs): Likewise.
 520
 521 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 522
 523         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 524         to convert a signal number with appropriate bounds checking.
 525
 526         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 527
 528 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 529
 530         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 531         print a newline to end the display anyway.
 532
 533         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 534         coprocessor status regs) when popping a frame.  This fixes
 535         float exceptions that occur after calling inferior functions.
 536
 537         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 538         Read and write the fsr (float status register) to/from the child
 539         process along with the float regs.  Remove Peter Schauer's change
 540         of May 24 '93, which has higher overhead and doesn't solve the
 541         real problem (which was that FSR wasn't being set).
 542
 543 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 544
 545         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 546         stack overflow check isn't right after the register stack
 547         adjustment instruction.  Metaware R2.3u compiler moves other
 548         things in front of it.  This fix isn't perfect but is what's
 549         running.
 550
 551 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 552
 553         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 554
 555         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 556         character filenames.
 557         * configure.in: Change accordingly.
 558
 559 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 560
 561         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 562         _filtered io routines from these two files.
 563
 564 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 565
 566         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 567         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 568         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 569         DEC c89.
 570         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 571
 572 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 573
 574         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 575         printing to gdb_stderr.
 576
 577         * remote-udi.c (udi_kill): Don't close the connection, just set
 578         inferior_pid to zero.
 579         (udi_mourn): Call remove_breakpoints.
 580
 581         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 582
 583         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 584
 585 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 586
 587         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 588
 589         * remote-bug.c: At the start of each section, reset srec_frame
 590         back to 160.
 591
 592         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 593         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 594         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 595         code which looks for those two waitkinds.  Use switch statement.
 596         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 597         CHILD_SPECIAL_WAITSTATUS.
 598
 599         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 600         * Move target_signal_from_host, target_signal_to_host, and
 601         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 602         * target.c: Include "wait.h" and <signal.h>.
 603         * target.h, infrun.c (proceed), proceed callers: Pass new code
 604         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 605         enums being treated as unsigned and is cleaner.
 606         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 607         TARGET_SIGNAL_0.
 608         * infcmd.c (signal_command), infrun.c (signals_info):
 609         Don't allow user to specify numeric equivalent of
 610         TARGET_SIGNAL_DEFAULT.
 611
 612 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 613
 614         * config/alpha/alpha-netware.mt:  New target support for Alpha
 615         running Netware.
 616         * configure.in:  Add alpha-*-netware* target.
 617
 618 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 619
 620         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 621
 622 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 623
 624         * target.h: Add enum target_waitkind, enum target_signal, and
 625         struct target_waitstatus.  Change status argument to target_wait to
 626         be struct target_waitstatus * instead of int *.
 627         * target.h, infrun.c, all targets: Change type of signal arguments
 628         to resume(), proceed(), and target_resume() from int to enum
 629         target_signal.
 630         * All targets (*_wait, *_resume): Change accordingly.
 631         * infcmd.c (program_info, signal_command), throughout infrun.c,
 632         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 633         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 634         signal code stuff right with the new signals would be non-trivial).
 635         * inferior.h (stop_signal): Make it enum target_signal not int.
 636         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 637         target_signal_from_name): New functions.
 638         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 639         store_waitstatus): New functions.
 640         * procfs.c (procfs_notice_signals): Use them.
 641         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 642         print_fault.
 643         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 644
 645         * objfiles.c (build_objfile_section_table): Don't abort() if
 646         objfile->sections is already set.
 647
 648         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 649         to match recent change to exec.c.
 650
 651         * Version 4.11.3.
 652
 653         * main.c (print_gdb_version): Change year to 1994.
 654
 655         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 656         * Makefile.in (NONSRC): Add ChangeLog-93.
 657
 658 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 659
 660         * stabsread.c (read_type): Allow defining several type numbers
 661         at once (e.g. "(1,2)=(3,4)="...).
 662
 663         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 664
 665         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 666
 667 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 668
 669         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 670         to process_one_symbol.
 671         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
