   1 Sat Jan 29 07:44:59 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
   2
   3         * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
   4         If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
   5         to achieve the desired timeout.
   6         * serial.h (serial_t): Add field timeout_remaining.
   7
   8 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
   9
  10         * c-exp.y (yylex): Reenable nested type code.

  21         with the old tm-m68k-em.h:
  22         (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
  23         (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
  24         (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
  25         Add FIXME regarding GET_LONGJMP_TARGET.
  26
  27         * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
  28         * infptrace.c (kill_inferior): Add comments.
  29         * main.c (quit_command): Call target_close after we kill or
  30         detach.
  31         * remote-udi.c (udi_close): Don't error() if QUITTING.
  32
  33 Fri Jan 28 11:55:52 1994  Rob Savoye  (rob@darkstar.cygnus.com)
  34
  35         * configure.in: Make m68k-coff and aout add monitor support in
  36         addition to the standard serial support.
  37
  38 Fri Jan 28 08:45:02 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
  39
  40         * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
  41         index indexNil.
  42
  43 Fri Jan 28 10:40:34 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  44
  45         * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
  46         * elfread.c (record_minimal_symbol_and_info),
  47         dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
  48
  49 Thu Jan 27 15:12:23 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  50
  51         * i386-stub.c: Add ".text" right before "mem_fault:".
  52
  53         * main.c (baud_rate): Add FIXME comment about printing -1 value.
  54
  55         * remote-utils.c (usage): Fix message to be accurate and conform
  56         more closely to normal conventions.
  57
  58         * remote-utils.c (gr_files_info): Have the exec_bfd test control
  59         whether to show information about exec_bfd, and not control whether
  60         to show information about device and speed.
  61
  62         * remote-utils.c (gr_open): If sr_get_device returns NULL, give
  63         usage message, don't dump core.
  64
  65         * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
  66         for variable size array.
  67         (bug_fetch_register, bug_store_register): Rename "value" to
  68         "fpreg_buf" because some compilers don't like variables whose
  69         names are the same as types.
  70         (bug_store_register): Use a cast when converting char * to
  71         unsigned char *.
  72
  73         * symmisc.c (maintenance_print_symbols): Don't refer to the name
  74         of the command in error message (the text was referring to the old
  75         name of the command).
  76
  77         * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
  78
  79         * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
  80         full details on structure elements without names.  This partially
  81         reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
  82         of those changes was accidental.
  83
  84         * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
  85         defined, make it an error to specify a single argument which is not
  86         a frame number.
  87
  88         * Makefile.in (version.c), main.c (print_gdb_version): Use
  89         host_alias and target_alias, not host_canonical and
  90         target_canonical, to print configuration.
  91
  92 Wed Jan 26 10:57:21 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  93
  94         * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
  95         of builtin_type_long.  It is necessary to get a type which is
  96         TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
  97
  98         Fix many sins which will come up in 32 bit x 64 bit GDB, and
  99         various miscellaneous things discovered in the process:
 100         * printcmd.c, defs.h (print_address_numeric): New function.
 101         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
 102         breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
 103         cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
 104         printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
 105         Use it.
 106         * utils.c, defs.h (gdb_print_address): New function.
 107         * expprint (dump_expression), gdbtypes.h: Use it.
 108         * breakpoint.c (describe_other_breakpoints),
 109         symmisc.c (dump_symtab, print_symbol):
 110         Use filtered not unfiltered I/O.
 111         (remove_breakpoints): Remove BREAKPOINT_DEBUG code.  Might as well
 112         just run gdb under a debugger for this (and it had problems with
 113         printing addresses, how to print b->shadow, etc.).
 114         * buildsym.c (make_blockvector), core.c (memory_error),
 115         exec.c (print_section_info), maint.c (print_section_table),
 116         mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
 117         symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
 118         Add comments saying code is broken.  Marked with "FIXME-32x64".
 119         * dbxread.c (process_one_symbol), partial-stab.h (default),
 120         remote-vx.c (vx_run_files_info):
 121         Don't cast int being passed to local_hex_string.
 122         * symmisc.c (print_symbol): Don't cast long being passed to %lx.
 123         * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
 124         only being a long.
 125         * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
 126         and LOC_LOCAL.
 127         * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
 128         * source.c: Include <sys/types.h> regardless of USG.
 129
 130 Tue Jan 25 12:58:26 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 131
 132         * valops.c (value_assign):  Set `type' after coercing toval.
 133         * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
 134         Use extract_unsigned_integer to get the address of a reference.
 135
 136 Tue Jan 25 11:31:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 137
 138         * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
 139         AIX can use ? instead of \ for continuation.  Deal with it.
 140
 141         * paread.c (read_unwind_info): Just assign to objfile->obj_private,
 142         not OBJ_UNWIND_INFO.  Assigning to a cast is a GCC-ism which
 143         the HP compiler in ANSI mode doesn't like.
 144
 145         * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
 146         based on USG, rather than defining HAVE_SIGSETMASK to an
 147         expression containing defined.  Having a macro used in #if expand
 148         to an expression containing "defined" is undefined according to
 149         ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
 150         it to.
 151
 152 Mon Jan 24 20:51:29 1994  John Gilmore  (gnu@cygnus.com)
 153
 154         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 155         Clean up the changes of 11 Jan, as recommended by Peter Schauer.
 156
 157 Fri Jan 21 19:10:44 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 158
 159         * ch-exp.y (match_string_literal):  Allow a zero-length string.
 160         * ch-lang.c (chill_printstr):  Don't print zero-length string funny.
 161
 162 Sat Jan 22 17:08:48 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 163
 164         * i386aix-nat.c (i386_float_info): Reverse order of registers before
 165         passing them to print_387_status.
 166         (print_387_status): Don't subtract top from 7 before using it.
 167         * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
 168         from 7; the above explains it.
 169
 170 Sat Jan 22 20:25:11 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 171
 172         * mips-tdep.c (init_extra_frame_info):  Use frame relative stack
 173         pointer value when fixing up the frame at the start of a function.
 174
 175 Sat Jan 22 12:29:13 1994  Stu Grossman  (grossman at cygnus.com)
 176
 177         * lynx-nat.c (fetch_core_registers):  Load the I & L regs for the
 178         Sparc from the stack.
 179
 180 Sat Jan 22 08:30:42 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 181
 182         * remote-mips.c (mips_initialize): Clear mips_initializing via
 183         cleanup chain, not directly.
 184
 185         * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
 186         of -1 mean forever, like in the HAVE_SGTTY case.  Warn if we are
 187         munging the timeout due to the limited range of c_cc[VTIME].
 188
 189         * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
 190         * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
 191         m3-nat.c (m3_create_inferior): Pass it.
 192         * procfs.c: Remove ptrace function.  It was declared in a way which
 193         conflicted with the prototype in unistd.h on Solaris.
 194
 195 Sat Jan 22 01:37:40 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 196
 197         * sparc-tdep.c (frame_saved_pc):  Get the pc from the saved pc
 198         in the sigcontext if it is a signal trampoline frame.
 199         * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
 200         Define for Solaris2.
 201
 202 Sat Jan 22 00:34:47 1994  Stu Grossman  (grossman at cygnus.com)
 203
 204         * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
 205         config/sparc/tm-sparclynx.h:  Move defs of FRAME_SAVED_I0/L0 to
 206         tm-sparc.h so they can be overridden if necessary.
 207
 208 Fri Jan 21 17:49:28 1994  Stu Grossman  (grossman at cygnus.com)
 209
 210         * lynx-nat.c:  Add Sparc support.
 211         * sparcly-nat.c:  Remove.  It's useless.

 213         * config/sparc/sparclynx.mh (NATDEPFILES):  Replace sparcly-nat.o
 214         with lynx-nat.o
 215         * config/sparc/tm-sparclynx.h:  Rewrite.
 216
 217 Fri Jan 21 19:08:48 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 218
 219         * rs6000-pinsn.c: Use the new disassembler in the opcodes
 220         directory.  Old code was discarded, since the new opcode table has
 221         a different format.
 222
 223 Fri Jan 21 14:28:30 1994  Fred Fish  (fnf@cygnus.com)
 224
 225         * Makefile.in (realclean):  Remove info files per make-stds.texi.
 226
 227 Fri Jan 21 12:47:53 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 228
 229         * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
 230         if N_SO_ADDRESS_MAYBE_MISSING is defined.
 231         * config/sparc/tm-sun4sol2.h: Define it.
 232
 233 Thu Jan 20 15:04:24 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 234
 235         * printcmd.c (print_address_symbolic):  Unconditionally use msymbol
 236         if we did not find a symbol.
 237
 238 Fri Jan 21 08:20:18 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 239
 240         * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
 241         is not defined.
 242
 243         * hppab-nat.c (call_ptrace): Delete redundant function.
 244         (kill_inferior, attach, detach, child_resume): Likewise.
 245         (child_xfer_memory): Likewise.
 246
 247         * hppah-nat.c (call_ptrace): Delete redundant function.
 248         (kill_inferior, attach, detach, child_resume): Likewise.
 249
 250         * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
 251
 252         * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
 253
 254         * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
 255
 256         * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
 257         (CHILD_XFER_MEMORY): Define.
 258         (PT_*): Define so that generic infptrace.c code can be used.
 259
 260 Fri Jan 21 09:23:33 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 261
 262         * xcoffread.c (xcoff_symfile_read): Make second parameter a
 263         struct section_offsets *, not a (nonexistent) struct section_offset *.
 264
 265         * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
 266         internal_xcoff_symtab, not an array of one of them.  Change lots of
 267         "main_aux" to "&main_aux" and so on.
 268
 269         * coffread.c, xcoffread.c: Include <coff/internal.h>
 270         before "symfile.h".
 271
 272 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 273
 274         * coffread.c (coff_getfilename): Make it not static.
 275
 276         * xcoffread.c (read_xcoff_symtab): complain() not abort().
 277
 278         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
 279         a completely gratuitous difference between xcoffread.c and coffread.c).
 280
 281 Wed Jan 19 15:09:44 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 282
 283         * infrun.c (wait_for_inferior): Don't set frame for
 284         step_resume_breakpoint for IN_SIGTRAMP cases.
 285
 286         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
 287         breakpoint.c (bpstat_what): Move step_resume from its own field of
 288         the struct bpstat_what into the main_action.  Make it override
 289         other breakpoints.  This is a conservative change in the sense
 290         that before the step resume breakpoint was a breakpoint.c
 291         breakpoint, hitting the step resume breakpoint overrode even
 292         calling bpstat_stop_status.
 293
 294 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 295
 296         * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
 297         in case execution was stopped in the called function.
 298         * stack.c (print_frame_info, frame_info):  If backtracing through
 299         a call dummy, handle the starting source line number on a line
 300         boundary like backtracing through sigtramp.
 301         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
 302         for call dummy frame right.  Remove old test for dummy frame,
 303         it has been unused at least since gdb-3.5.
 304         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
 305         of the dummy frame.
 306
 307 Tue Jan 18 16:16:35 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 308
 309         * infcmd.c (signal_command): Accept 0 as legitimate signal number.
 310
 311 Tue Jan 18 14:09:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 312
 313         * infrun.c (signals_info), target.c (target_signal_from_name):
 314         Use ugly casts to avoid enumvar < enumvar or enumvar++.
 315
 316 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 317
 318         * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
 319         * inflow.c (terminal_ours_1): When discussing how to deal with the
 320         tty state, make note of query() as well as readline.
 321
 322         * infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
 323         signals for which stop and print are cleared by default.
 324
 325 Mon Jan 17 20:00:51 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 326
 327         * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
 328         reserved fields to hold a stub unwind entry type.  Fix typo.

 333         by linker stub unwind descriptors.
 334         (frameless_function_invocation): Likewise.
 335         (frame_chain_valid): Likewise.
 336         * paread.c (compare_unwind_entries): New function for sorting
 337         unwind table entries.
 338         (read_unwind_info): Rewrite to remove dependency on host endianness.
 339         Read in data from the $UNWIND_END$ subspace which contains linker
 340         stub unwind descriptors.  Merge that data into the basic unwind
 341         table.
 342
 343         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
 344
 345 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 346
 347         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
 348         from either the symbol name or the auxent.
 349         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
 350         no longer static.
 351

 353
 354         * Makefile.in (ALLPARAM):  Change irix5.h to nm-irix5.h.

 361
 362         * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL

 376         within_function.
 377

 384 Sat Jan 15 18:27:34 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 385
 386         * main.c (show_commands):  Make return type of extern
 387         history_get be HIST_ENTRY, rather than struct _hist_entry.
 388         (The latter loses with the upcoming merged readline.)
 389
 390 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 391
 392         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring

 394
 395         * symtab.h (struct symbol): Make section short, not unsigned short.
 396
 397         * symtab.c (lookup_symbol): Add comment about QUIT here.
 398
 399         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 400
 401         * c-exp.y (parse_number): Check for overflow regardless of range
 402         checking.  Fix overflow check to use unsigned LONGEST, not
 403         unsigned int.
 404
 405         * c-exp.y (parse_number): Make it so that integer constants are
 406         builtin_type_long_long if builtin_type_long isn't big enough or if
 407         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 408
 409         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 410         Print our "()" first, then recurse for the target type.
 411
 412 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 413
 414         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 415
 416         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
 417
 418 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 419
 420         * utils.c (request_quit): Re-establish signal handler regardless
 421         of USG.
 422
 423         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 424
 425 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 426

 428
 429 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 430
 431         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 432
 433 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 434
 435         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 436         changes (status -> ourstatus; declare status, etc.).
 437         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
 438
 439 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 440
 441         * Makefile.in (ALLPARAM): Add config/nm-lynx.h.

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

 666 Tue Jan  4 14:51:35 1994  Stan Shebs  (shebs@andros.cygnus.com)
 667
 668         * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
 669
 670 Tue Jan  4 09:47:14 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 671
 672         * target.h: Add enum target_waitkind, enum target_signal, and
 673         struct target_waitstatus.  Change status argument to target_wait to
 674         be struct target_waitstatus * instead of int *.
 675         * target.h, infrun.c, all targets: Change type of signal arguments
 676         to resume(), proceed(), and target_resume() from int to enum
 677         target_signal.
 678         * All targets (*_wait, *_resume): Change accordingly.
 679         * infcmd.c (program_info, signal_command), throughout infrun.c,
 680         * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
 681         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 682         signal code stuff right with the new signals would be non-trivial).
 683         * inferior.h (stop_signal): Make it enum target_signal not int.
 684         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 685         target_signal_from_name): New functions.
 686         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 687         store_waitstatus): New functions.
 688         * procfs.c (procfs_notice_signals): Use them.
 689         * i960-tdep.c (i960_fault_to_signal): New function, to replace
 690         print_fault.
 691         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 692
 693         * objfiles.c (build_objfile_section_table): Don't abort() if
 694         objfile->sections is already set.
 695
 696         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 697         to match recent change to exec.c.
 698
 699         * Version 4.11.3.
 700
 701         * main.c (print_gdb_version): Change year to 1994.
 702
 703         * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
 704         * Makefile.in (NONSRC): Add ChangeLog-93.

 707
 708         * stabsread.c (read_type): Allow defining several type numbers
 709         at once (e.g. "(1,2)=(3,4)="...).
 710
 711         * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
 712
 713         * breakpoint.c (frame_in_dummy): Check PC as well as frame.

 716
 717         * mdebugread.c (psymtab_to_symtab_1):  Only pass N_STAB symbols
 718         to process_one_symbol.
 719         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 720         avoid caching a bad endaddr in find_pc_partial_function.

 723
