   1 Thu Jan 20 17:30:55 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
   2
   3         * coffread.c (coff_getfilename): Make it not static.
   4
   5         * xcoffread.c (read_xcoff_symtab): complain() not abort().
   6
   7         * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
   8         a completely gratuitous difference between xcoffread.c and coffread.c).
   9
  10 Wed Jan 19 15:09:44 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  11
  12         * infrun.c (wait_for_inferior): Don't set frame for
  13         step_resume_breakpoint for IN_SIGTRAMP cases.
  14
  15         * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
  16         breakpoint.c (bpstat_what): Move step_resume from its own field of
  17         the struct bpstat_what into the main_action.  Make it override
  18         other breakpoints.  This is a conservative change in the sense
  19         that before the step resume breakpoint was a breakpoint.c
  20         breakpoint, hitting the step resume breakpoint overrode even
  21         calling bpstat_stop_status.
  22
  23 Wed Jan 19 12:40:25 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
  24
  25         * infrun.c (normal_stop):  Set stop_pc after popping the dummy frame
  26         in case execution was stopped in the called function.
  27         * stack.c (print_frame_info, frame_info):  If backtracing through
  28         a call dummy, handle the starting source line number on a line
  29         boundary like backtracing through sigtramp.
  30         * sparc-tdep.c (sparc_frame_find_saved_regs):  Get frame address
  31         for call dummy frame right.  Remove old test for dummy frame,
  32         it has been unused at least since gdb-3.5.
  33         * sparc-tdep.c (sparc_push_dummy_frame):  Set return address register
  34         of the dummy frame.

  42         * infrun.c (signals_info), target.c (target_signal_from_name):
  43         Use ugly casts to avoid enumvar < enumvar or enumvar++.
  44
  45 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  46
  47         * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
  48         * inflow.c (terminal_ours_1): When discussing how to deal with the
  49         tty state, make note of query() as well as readline.

  52         signals for which stop and print are cleared by default.
  53
  54 Mon Jan 17 20:00:51 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
  55
  56         * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
  57         reserved fields to hold a stub unwind entry type.  Fix typo.

  62         by linker stub unwind descriptors.
  63         (frameless_function_invocation): Likewise.
  64         (frame_chain_valid): Likewise.
  65         * paread.c (compare_unwind_entries): New function for sorting
  66         unwind table entries.
  67         (read_unwind_info): Rewrite to remove dependency on host endianness.
  68         Read in data from the $UNWIND_END$ subspace which contains linker
  69         stub unwind descriptors.  Merge that data into the basic unwind
  70         table.
  71
  72         * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
  73
  74 Mon Jan 17 22:00:15 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  75
  76         * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
  77         from either the symbol name or the auxent.
  78         * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
  79         no longer static.

  82
  83         * Makefile.in (ALLPARAM):  Change irix5.h to nm-irix5.h.

  88
  89 Mon Jan 17 11:15:57 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
  90
  91         * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL

  95
  96         * Makefile.in (init.c): Add comment explaining formatting conventions.
  97
  98         * c-exp.y (parse_number): Assign to temporary between the right
  99         shifts, to work around a bug in the SCO compiler.
 100
 101         * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
 102         Add various files which were added to GDB recently.

 105         within_function.
 106
 107         * Makefile.in: Add mostlyclean target.
 108
 109 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 110
 111         * Version 4.11.4.
 112
 113 Sat Jan 15 18:27:34 1994  Per Bothner  (bothner@kalessin.cygnus.com)
 114
 115         * main.c (show_commands):  Make return type of extern
 116         history_get be HIST_ENTRY, rather than struct _hist_entry.
 117         (The latter loses with the upcoming merged readline.)
 118
 119 Sat Jan 15 10:20:13 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 120
 121         * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
 122         const char *, not char *.
 123
 124         * symtab.h (struct symbol): Make section short, not unsigned short.
 125
 126         * symtab.c (lookup_symbol): Add comment about QUIT here.
 127
 128         * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
 129
 130         * c-exp.y (parse_number): Check for overflow regardless of range
 131         checking.  Fix overflow check to use unsigned LONGEST, not
 132         unsigned int.
 133
 134         * c-exp.y (parse_number): Make it so that integer constants are
 135         builtin_type_long_long if builtin_type_long isn't big enough or if
 136         an "LL" suffix is used.  Properly handle "UL" or "LU" suffixes.
 137
 138         * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
 139         Print our "()" first, then recurse for the target type.
 140
 141 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 142
 143         * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
 144
 145         * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
 146
 147 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 148
 149         * utils.c (request_quit): Re-establish signal handler regardless
 150         of USG.
 151
 152         * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
 153
 154 Fri Jan 14 21:55:39 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 155
 156         * i960-tdep.c: Include target.h.
 157
 158 Fri Jan 14 17:12:28 1994  Stan Shebs  (shebs@andros.cygnus.com)
 159
 160         * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
 161
 162 Fri Jan 14 11:06:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 163
 164         * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
 165         changes (status -> ourstatus; declare status, etc.).
 166         * config/nm-lynx.h: Fix child_wait prototype and include target.h.
 167
 168 Fri Jan 14 14:17:06 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 169
 170         * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
 171
 172 Fri Jan 14 11:49:44 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 173
 174         * remote-mips.c (mips_request, mips_wait): Correct prototypes.
 175
 176 Fri Jan 14 11:37:17 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 177
 178         * config/i386/xm-linux.h: Define HAVE_TERMIOS.
 179
 180 Fri Jan 14 01:04:36 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 181
 182         * config/alpha/tm-alpha.h (CALL_DUMMY):  Improve comment.
 183
 184 Thu Jan 13 10:32:38 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 185
 186         * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
 187         is defined.  Otherwise just report TARGET_SIGNAL_UNKNOWN.
 188
 189         * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
 190         writing it.
 191
 192         Add search to target vector (#if 0'd until after 4.12):
 193         * target.h (to_search, target_search): Add.
 194         * gdbcore.h, core.c (generic_search): Add.
 195         * remote.c (remote_search): Add.
 196         * a29k-tdep.c (init_frame_info): Use target_search to find traceback
 197         tag.
 198
 199         * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
 200         is on, call find_pc_function rather than relying just on the minimal
 201         symbols (probably only matters for symbol readers which don't put
 202         statics in the minimal symbols, but changing this strikes me as
 203         not conservative enough).
 204         Initialize name_location in all cases.
 205         If no symbol and no msymbol, don't print anything symbolic.
 206
 207         * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
 208
 209 Wed Jan 12 20:53:16 1994  John Gilmore  (gnu@cygnus.com)
 210
 211         * printcmd.c (print_address_symbolic):  Make it search the
 212         symtabs for variables as well as functions.  Add `set print
 213         fast-symbolic-addr' and default it to fast (the old way).
 214         Print line numbers for data items as well as functions.
 215
 216         * symtab.c (find_addr_symbol):  Return the symtab and the symbol
 217         address, if a symbol is found (take two more args pointing to
 218         where to store these results).
 219
 220         * symtab.h (find_addr_symbol):  Add prototype.
 221
 222 Wed Jan 12 19:32:11 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 223
 224         * objfiles.h: Fix comments to reflect the fact that the phrase
 225         "top of stack" always refers to where the pushing and popping takes
 226         place, regardless of whether it is at the highest or lowest address.
 227
 228 Wed Jan 12 13:23:37 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 229
 230         * mdebugread.c (parse_symbol):  Do not set TYPE_TAG_NAME for
 231         compiler generated tag names.
 232         * mdebugread.c (parse_type):  Handle cross references to qualified
 233         aggregate types.
 234         * valops.c (value_struct_elt):  Improve error message if the
 235         address of a method is requested from an object instance.
 236         * valops.c (search_struct_method):  Make name_matched non-static
 237         to get it initialized correctly.
 238         * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER):  Define to
 239         exclude segment register which are not writable on newer SCO versions.
 240
 241 Wed Jan 12 14:44:45 1994  Jim Kingdon  (kingdon@lioth.cygnus.com)
 242
 243         * go32-xdep.c: Remove unused function uerror.
 244         (sigsetmask): Declare return type.  Declare argument (to match the
 245         way it is called).  Explicitly return 0.
 246
 247 Wed Jan 12 01:44:25 1994  John Gilmore  (gnu@cygnus.com)
 248
 249         * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
 250         partial_symbol):  Shrink the storage sizes of symbols, by making
 251         enums into 1-byte bitfields when compiled __GNUC__, moving all the
 252         enums and small ints to the end of each struct to improve
 253         alignment, and switching the section number from int to unsigned
 254         short.
 255
 256 Wed Jan 12 00:16:26 1994  John Gilmore  (gnu@cygnus.com)
 257
 258         * symtab.c (find_addr_symbol):  New routine that will find the nearest
 259         symbol associated with an address.  It does so by exhaustive
 260         search of the symtabs, so it's slow but complete.
 261
 262 Tue Jan 11 23:57:30 1994  John Gilmore  (gnu@cygnus.com)
 263
 264         * coffread.c (read_coff_symtab):  Set PC bounds of _globals_ symtab
 265         to [0,0] rather than [0, end of first source file].  This avoids
 266         problems with other parts of GDB looking for linetables in the
 267         _globals_ symtab.  Eliminate variables num_object_files and
 268         first_object_file_end.
 269
 270 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 271
 272         * a29k-tdep.c (init_frame_info):  Cast null arg to examine_tag.
 273         (pop_frame):  Restore PC2 and LR0 from dummy frames.
 274         (push_dummy_frame):  Save PC2 and LR0 into dummy frames.
 275         (setup_arbitrary_frame):  Handle 3 args and set up real frames.
 276         * config/a29k/tm-a29k.h (FRAME_NUM_ARGS):  Update comments.
 277         (DUMMY_FRAME_RSIZE):  Add 2 longwords for PC2 and LR0.
 278         (SETUP_ARBITRARY_FRAME):  Define.
 279
 280 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 281
 282         * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
 283
 284 Tue Jan 11 14:27:03 1994  Ian Lance Taylor  (ian@tweedledumb.cygnus.com)
 285
 286         * remote-udi.c (udi_resume): Correct prototype.
 287
 288 Tue Jan 11 11:10:30 1994  Jeffrey A. Law  (law@snake.cs.utah.edu)
 289
 290         * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
 291         hppa_frame_find_saved_regs.
 292         * hppa-tdep.c (dig_fp_from_stack): Delete function.
 293         (prologue_inst_adjust_sp): New function.
 294         (is_branch, inst_saves_gr, inst_saves_fr): New functions.
 295         (skip_prologue): Completely rewrite to use unwind information.
 296         (hppa_frame_find_saved_regs): Likewise.
 297
 298 Tue Jan 11 06:59:10 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 299
 300         * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
 301         to convert a signal number with appropriate bounds checking.
 302
 303         * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
 304
 305 Tue Jan 11 00:53:46 1994  John Gilmore  (gnu@cygnus.com)
 306
 307         * stack.c (frame_info):  If FRAME_FIND_SAVED_REGS isn't defined,
 308         print a newline to end the display anyway.
 309
 310         * sparc-tdep.c (sparc_pop_frame):  Pop the fsr and csr (float and
 311         coprocessor status regs) when popping a frame.  This fixes
 312         float exceptions that occur after calling inferior functions.
 313
 314         * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
 315         Read and write the fsr (float status register) to/from the child
 316         process along with the float regs.  Remove Peter Schauer's change
 317         of May 24 '93, which has higher overhead and doesn't solve the
 318         real problem (which was that FSR wasn't being set).
 319
 320 Mon Jan 10 23:16:42 1994  John Gilmore  (gnu@cygnus.com)
 321
 322         * a29k-tdep.c (examine_prologue):  Don't worry if the ASGEQ
 323         stack overflow check isn't right after the register stack
 324         adjustment instruction.  Metaware R2.3u compiler moves other
 325         things in front of it.  This fix isn't perfect but is what's
 326         running.
 327
 328 Mon Jan 10 20:08:23 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 329
 330         * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
 331
 332         * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
 333         character filenames.
 334         * configure.in: Change accordingly.
 335
 336 Mon Jan 10 15:48:36 1994  Tom Lord  (lord@rtl.cygnus.com)
 337
 338         * m68k-stub.c, sparc-stub.c: removed spurious introduction of
 339         _filtered io routines from these two files.
 340
 341 Fri Jan  7 12:42:45 1994  Peter Schauer  (pes@regent.e-technik.tu-muenchen.de)
 342
 343         * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
 344         config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET):  Define.

 352         printing to gdb_stderr.
 353
 354         * remote-udi.c (udi_kill): Don't close the connection, just set
 355         inferior_pid to zero.
 356         (udi_mourn): Call remove_breakpoints.
 357
 358         * remote-udi.c: Remove obsolete need_artificial_traps comment.
 359
 360         * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.

 362 Thu Jan  6 07:17:53 1994  Jim Kingdon  (kingdon@deneb.cygnus.com)
 363
 364         * symtab.c (lookup_symbol): Don't try adding .c to the name.
 365
 366         * remote-bug.c: At the start of each section, reset srec_frame
 367         back to 160.

 369         * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
 370         * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
 371         * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
 372         code which looks for those two waitkinds.  Use switch statement.
 373         * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
 374         CHILD_SPECIAL_WAITSTATUS.

 377         * Move target_signal_from_host, target_signal_to_host, and

 380         * target.h, infrun.c (proceed), proceed callers: Pass new code

 384         TARGET_SIGNAL_0.

 404         * target.h, infrun.c, all targets: Change type of signal arguments
 405         to resume(), proceed(), and target_resume() from int to enum

 410         * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
 411         signal code stuff right with the new signals would be non-trivial).
 412         * inferior.h (stop_signal): Make it enum target_signal not int.
 413         * target.c, target.h (target_signal_to_string, target_signal_to_name,
 414         target_signal_from_name): New functions.
 415         * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
 416         store_waitstatus): New functions.
 417         * procfs.c (procfs_notice_signals): Use them.

 419         print_fault.
 420         * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
 421
 422         * objfiles.c (build_objfile_section_table): Don't abort() if
 423         objfile->sections is already set.
 424
 425         * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
 426         to match recent change to exec.c.

 436
 437         * stabsread.c (read_type): Allow defining several type numbers
 438         at once (e.g. "(1,2)=(3,4)="...).

 447         to process_one_symbol.
 448         * symtab.c (find_pc_psymbol):  Search global_psymbols as well to
 449         avoid caching a bad endaddr in find_pc_partial_function.
