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

 186         if we did not find a symbol.
 187
 188 Fri Jan 21 08:20:18 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 189
 190         * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
 191         is not defined.
 192
 193         * hppab-nat.c (call_ptrace): Delete redundant function.
 194         (kill_inferior, attach, detach, child_resume): Likewise.

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

 316
 317         * Makefile.in (init.c): Add comment explaining formatting conventions.
 318
 319         * c-exp.y (parse_number): Assign to temporary between the right
 320         shifts, to work around a bug in the SCO compiler.
 321
 322         * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
 323         Add various files which were added to GDB recently.
 324

 335
 336         * main.c (show_commands):  Make return type of extern
 337         history_get be HIST_ENTRY, rather than struct _hist_entry.
 338         (The latter loses with the upcoming merged readline.)
 339
 340 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 341
 342         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
 343         const char *, not char *.
 344
 345         * symtab.h (struct symbol): Make section short, not unsigned short.
 346
 347         * symtab.c (lookup_symbol): Add comment about QUIT here.
 348
 349         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 350
 351         * c-exp.y (parse_number): Check for overflow regardless of range
 352         checking.  Fix overflow check to use unsigned LONGEST, not
 353         unsigned int.
 354
 355         * c-exp.y (parse_number): Make it so that integer constants are
 356         builtin_type_long_long if builtin_type_long isn't big enough or if
 357         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 358
 359         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 360         Print our "()" first, then recurse for the target type.
 361
 362 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 363
 364         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 365
 366         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
 367
 368 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 369
 370         * utils.c (request_quit): Re-establish signal handler regardless
 371         of USG.
 372
 373         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 374
 375 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 376
 377         * i960-tdep.c: Include target.h.
 378
 379 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 380
 381         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 382
 383 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 384
 385         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 386         changes (status -> ourstatus; declare status, etc.).
 387         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
 388
 389 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 390
 391         * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
 392
 393 Fri Jan 14 11:49:44 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 394
 395         * remote-mips.c (mips_request, mips_wait): Correct prototypes.
 396
 397 Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 398
 399         * config/i386/xm-linux.h: Define HAVE_TERMIOS.
 400
 401 Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 402
 403         * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.
 404
 405 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 406
 407         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 408         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 409
 410         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 411         writing it.
 412
 413         Add search to target vector (#if 0'd until after 4.12):
 414         * target.h (to_search, target_search): Add.
 415         * gdbcore.h, core.c (generic_search): Add.
 416         * remote.c (remote_search): Add.
 417         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 418         tag.
 419
 420         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 421         is on, call find_pc_function rather than relying just on the minimal
 422         symbols (probably only matters for symbol readers which don't put
 423         statics in the minimal symbols, but changing this strikes me as
 424         not conservative enough).
 425         Initialize name_location in all cases.
 426         If no symbol and no msymbol, don't print anything symbolic.
 427
 428         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 429
 430 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 431
 432         * printcmd.c (print_address_symbolic):  Make it search the
 433         symtabs for variables as well as functions.  Add `set print
 434         fast-symbolic-addr' and default it to fast (the old way).
 435         Print line numbers for data items as well as functions.
 436
 437         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 438         address, if a symbol is found (take two more args pointing to
 439         where to store these results).
 440
 441         * symtab.h (find_addr_symbol):  Add prototype.
 442
 443 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 444
 445         * objfiles.h: Fix comments to reflect the fact that the phrase
 446         "top of stack" always refers to where the pushing and popping takes
 447         place, regardless of whether it is at the highest or lowest address.
 448
 449 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 450
 451         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 452         compiler generated tag names.
 453         * mdebugread.c (parse_type):  Handle cross references to qualified
 454         aggregate types.
 455         * valops.c (value_struct_elt):  Improve error message if the
 456         address of a method is requested from an object instance.
 457         * valops.c (search_struct_method):  Make name_matched non-static
 458         to get it initialized correctly.
 459         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 460         exclude segment register which are not writable on newer SCO versions.
 461
 462 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 463
 464         * go32-xdep.c: Remove unused function uerror.
 465         (sigsetmask): Declare return type.  Declare argument (to match the
 466         way it is called).  Explicitly return 0.
 467
 468 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 469
 470         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 471         partial_symbol):  Shrink the storage sizes of symbols, by making
 472         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 473         enums and small ints to the end of each struct to improve
 474         alignment, and switching the section number from int to unsigned
 475         short.
 476
 477 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 478
 479         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 480         symbol associated with an address.  It does so by exhaustive
 481         search of the symtabs, so it's slow but complete.
 482
 483 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 484
 485         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 486         to [0,0] rather than [0, end of first source file].  This avoids
 487         problems with other parts of GDB looking for linetables in the
 488         _globals_ symtab.  Eliminate variables num_object_files and
 489         first_object_file_end.
 490
 491 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 492
 493         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 494         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 495         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 496         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 497         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 498         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 499         (SETUP_ARBITRARY_FRAME):  Define.
 500
 501 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 502
 503         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 504
 505 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 506
 507         * remote-udi.c (udi_resume): Correct prototype.
 508
 509 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 510
 511         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 512         hppa_frame_find_saved_regs.
 513         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 514         (prologue_inst_adjust_sp): New function.
 515         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 516         (skip_prologue): Completely rewrite to use unwind information.
 517         (hppa_frame_find_saved_regs): Likewise.
 518
 519 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 520
 521         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 522         to convert a signal number with appropriate bounds checking.
 523
 524         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 525
 526 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 527
 528         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 529         print a newline to end the display anyway.
 530
 531         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 532         coprocessor status regs) when popping a frame.  This fixes
 533         float exceptions that occur after calling inferior functions.
 534
 535         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 536         Read and write the fsr (float status register) to/from the child
 537         process along with the float regs.  Remove Peter Schauer's change
 538         of May 24 '93, which has higher overhead and doesn't solve the
 539         real problem (which was that FSR wasn't being set).
 540
 541 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 542
 543         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 544         stack overflow check isn't right after the register stack
 545         adjustment instruction.  Metaware R2.3u compiler moves other
 546         things in front of it.  This fix isn't perfect but is what's
 547         running.
 548
 549 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 550
 551         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 552
 553         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 554         character filenames.
 555         * configure.in: Change accordingly.
 556
 557 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 558
 559         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 560         _filtered io routines from these two files.
 561
 562 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 563
 564         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 565         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.
 566         * mdebugread.c (parse_symbol):  Handle enum sh.type produced by
 567         DEC c89.
 568         * mdebugread.c (add_line):  Handle zero linenos produced by DEC c89.
 569
 570 Fri Jan  7 12:55:25 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 571
 572         * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
 573         printing to gdb_stderr.
 574
 575         * remote-udi.c (udi_kill): Don't close the connection, just set
 576         inferior_pid to zero.
 577         (udi_mourn): Call remove_breakpoints.
 578
 579         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 580
 581         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
 582
 583 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 584
 585         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 586
 587         * remote-bug.c: At the start of each section, reset srec_frame
 588         back to 160.
 589
 590         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 591         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 592         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 593         code which looks for those two waitkinds.  Use switch statement.
 594         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 595         CHILD_SPECIAL_WAITSTATUS.
 596
 597         * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
 598         * Move target_signal_from_host, target_signal_to_host, and
 599         store_waitstatus from inftarg.c to target.c.  procfs needs them.
 600         * target.c: Include "wait.h" and <signal.h>.
 601         * target.h, infrun.c (proceed), proceed callers: Pass new code
 602         TARGET_SIGNAL_DEFAULT instead of -1.  This avoids problems with
 603         enums being treated as unsigned and is cleaner.
 604         * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
 605         TARGET_SIGNAL_0.
 606         * infcmd.c (signal_command), infrun.c (signals_info):
 607         Don't allow user to specify numeric equivalent of
 608         TARGET_SIGNAL_DEFAULT.
 609
 610 Tue Jan  4 15:34:36 1994  Stu Grossman  (grossman@cygnus.com)
 611
 612         * config/alpha/alpha-netware.mt:  New target support for Alpha
 613         running Netware.
 614         * configure.in:  Add alpha-*-netware* target.
 615
 616 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 617
 618         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 619
 620 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 621
 622         * target.h: Add enum target_waitkind, enum target_signal, and
 623         struct target_waitstatus.  Change status argument to target_wait to
 624         be struct target_waitstatus * instead of int *.
 625         * target.h, infrun.c, all targets: Change type of signal arguments
 626         to resume(), proceed(), and target_resume() from int to enum
 627         target_signal.
 628         * All targets (*_wait, *_resume): Change accordingly.
 629         * infcmd.c (program_info, signal_command), throughout infrun.c,
 630         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 631         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 632         signal code stuff right with the new signals would be non-trivial).
 633         * inferior.h (stop_signal): Make it enum target_signal not int.
 634         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 635         target_signal_from_name): New functions.
 636         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 637         store_waitstatus): New functions.
 638         * procfs.c (procfs_notice_signals): Use them.
 639         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 640         print_fault.
 641         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 642
 643         * objfiles.c (build_objfile_section_table): Don't abort() if
 644         objfile->sections is already set.
 645
 646         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 647         to match recent change to exec.c.
 648
 649         * Version 4.11.3.
 650
 651         * main.c (print_gdb_version): Change year to 1994.
 652
 653         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 654         * Makefile.in (NONSRC): Add ChangeLog-93.
 655
 656 Mon Jan  3 11:57:29 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 657
 658         * stabsread.c (read_type): Allow defining several type numbers
 659         at once (e.g. "(1,2)=(3,4)="...).
 660
 661         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 662
 663         * breakpoint.c (frame_in_dummy): Check PC as well as frame.
 664
 665 Mon Jan  3 02:47:03 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 666
 667         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 668         to process_one_symbol.
 669         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
