1 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3 Cleanup for release 3.94.2:
5 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
6 include files. Roll version to 3.94.2.
8 * coffread.c (init_stringtab): Read length into unsigned char
9 array before swapping; don't assume 32-bit longs.
11 * target.c (target_info): Don't bother with get_sym_file, just use
12 the symfile global variable.
13 * symtab.h, symfile.c (get_sym_file): Delete it.
15 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
16 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
17 (read_type): Replace one more error() with complain().
19 * mipsread.c (parse_partial_symbols): Replace printf with complain.
21 * i960-tdep.c: Fix copyright attribution.
23 * config.gdb: Quote all backquotes in doublequotes. You can
24 quote me on that. BSD 4.4 shell found this one.
26 * infptrace.c (throughout): The third argument to ptrace is an
29 * infrun.c (wait_for_inferior): When program has terminated, we
30 have to call target_terminal_ours before we pop that target off
31 the stack (e.g. before a call to target_kill or
32 target_mourn_inferior). This fixes problem where a program
33 terminates, then GDB stops for (tty output) and you have to type
34 "fg" to the shell to resume it. FIXME: This code for what to
35 do after termination really should be in normal_stop instead.
37 * gdbcore.h (read_memory_check): Change declaration; it changed
40 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
41 4.4 prereleases, this avoids a bug in their sgtty compatability
43 * remote.c: Use terminal.h rather than hand-rolling the same.
45 * signame.c, signame.h (psignal): Arg is unsigned, not int.
46 * utils.c (strsave, strstr): Fix arg types.
47 * valprint.c (val_print): lint
49 MIPS symbol table support from Per Bothner:
51 * symfile.c (symtab_fns): Remove initializer table that needs to
52 be hacked for each new symbol file format supported.
53 (add_symtab_fns): New function, chains symbol table
54 handlers into the global list.
55 (symfile_init): Search this list.
56 * symfile.h: Add next pointer, declare add_symtab_fns.
57 * coffread.c (_initialize_coffread): Call add_symtab_fns.
58 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
60 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
61 symbol *). Thus, we no longer need the hack to trash
62 pst->filename. Good, since that hack confused code in symfile.c!
64 (reorder_symtabs, destroy_all_symtabs): Removed static
65 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
66 Instead, the latter now uses a temporary array (stack-allocated
67 from an obstack, and then freed).
69 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
70 haven't been set in the outermost stBlock of a procedure. This was
71 a problem with f77 binaries on Ultrix 4.?.
73 (new_symtab, new_symbol, new_type): Continue changing code to use
74 obstacks more and otherwise conform to dbxread internal style.
75 Made the free_code of symtabs be free_linetable (as in dbxread)
76 instead of free_contents. This implies memory leaks when reading
77 a new symbol table, until the conversion is finished. Did change
78 (struct symbol) and (struct type) to be allocated on the
79 symbol_obstack. Blocks and blockvectors are among the things
82 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
83 tested much, but it solved one problem (reported by Meissner), and
84 cleans up some other things. The problem happened when an
85 included file contains actual code (functions) and not just
86 definitions. The mips coff is a little inconvenient there, since
87 it may cause a procedure to be mapped to the wrong psymtab.
89 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
90 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
91 this will need work for the new core paradigm.
93 Opcode patches from the net:
95 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
96 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
97 missing altogether - they are added here. From Bruce Bauman.
98 * mips-opcode.h: The low mask for C0 instructions was too small.
99 From Garrett Lau. I modified the fix to check the entire 32-bit
102 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
105 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
107 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
109 * dbxread.c (read_type): Pointer subtraction (value_sub in
110 valarith.c) sometimes failed because the types of the
111 pointers being subtracted were not identical.
112 These differed because dbxread.c was allocating pointer types
113 using dbx_alloc_type+smash_to_pointer_type instead of
114 lookup_pointer_type. I failed to find a justification for the
115 former, so I changed it to use the latter. Similarly, I
116 replaced smash_to_function_type by lookup_function_type,
117 and smash_to_reference_type by lookup_reference_type.
119 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
120 _initialize_mipsread): corresponding changes.
122 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
124 * source.c (mod_path): Do tilde_expand on each component of the path,
125 rather than on the (list of) paths as a whole.
126 (print_source_lines): Set first_line_listed in addition to
127 current_source_symtab and current_source_line. If the source was
128 not findable, after a "dir" command to fix the problem,
129 a "list" would get the wrong lines.
131 While I was there... (gnu):
133 * dbxread.c (read_type): Change error to complaint.
135 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
137 First attempt at detailed understanding of symbol table memory alloc.
139 * dbxread.c (dbx_symfile_read): Free our string table if we
140 aren't the mainline. Free the "info" struct since we're done with
142 (init_psymbol_list): Free any previously allocated psymbol lists.
143 (): FIXME: Should realloc-down the psymbol lists when done reading
144 the main symbol file?
146 * symmisc.c (free_symtab): Free fullname field too.
148 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
149 (REGISTER_ADDR): Make result type unsigned int.
151 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
152 define REGEX must also define REGEX1 (its dependency).
154 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
156 * tconfig/i960: No longer works, points you at vxworks960 or
159 * xgdb.c, XGDB-README: Remove file. Users can get the much
161 * Makefile.dist: Remove all trace of xgdb.
163 * breakpoint.c (breakpoint_1): Pass demangle arg to
164 print_address_symbolic.
165 (clear_breakpoints): Remove unused function.
166 (breakpoint_re_set_one): Guts of breakpoint_re_set.
167 (breakpoint_re_set): Use catch_errors to do them all anyway.
169 * gdb-int.texinfo (Host versus Target): Add section on what is
170 a "host" feature versus what is a "target" feature.
172 * infcmd.c (path_command, path_info): Handle the PATH variable
173 (object search path) as conveniently as the source search path.
174 * environ.c (set_in_environ): Set some vars in GDB's environment,
175 in addition to the child's. PATH, G960BASE, G960BIN for starters.
176 * source.c (mod_path): New function, from guts of
177 directory_command, modifies a path. Used by path_command.
178 (directory_command): Call it.
179 * defs.h (strsave): Declare.
181 * utils.c (sevenbit_strings): Add new printing option.
183 (strsave): Provide this handy helper routine.
184 (set_width_command): Rename set_screen_width_command.
185 (_initialize_utils): "set screen-width" => "set width";
186 "set screen-height" => "set height"; add sevenbit-strings.
188 * infcmd.c (do_registers_info): Print floating point registers
189 in raw hex as well as float format, regardless of whether it is
190 a "virtual" convertible register.
191 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
192 regs as a double, just in case it's being used that way.
193 * values.c (unpack_long): Comment on array/function coercion.
194 (unpack_double): Argument is in target byte order now. For
195 integer arguments, just call unpack_long and float the result.
196 * m68k-tdep.c: include defs.h for "const" handling.
197 * remote-nindy.c: Use ieee-float stuff.
198 (nindy_fetch_registers): Unpack double regs to host double, then
200 (nindy_store_registers): Pack extendeds to host double, flip
201 around by misusing unpack_double, send as target double.
203 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
204 zero, as when stopped at the first instruction of a process.
206 * blockframe.c: Fix filename in comment (param.h => tm.h).
207 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
208 * tm-68k.h: Fix typos.
210 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
212 Changes from a bringup on the DEC Vax under Ultrix 4.0.
214 * coredep.c (fetch_core_registers): Pass end-address of register
215 section to register_addr as expected. Don't call supply_register
216 if we'd just pass it garbage.
218 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
220 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
222 * target.c (push_target, target_info): Cast enums to int for < or
225 * stack.c (print_frame_info): Identify source file & line
226 even if we can't print it.
228 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
230 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
232 Clean up IEEE floating point support.
234 * ieee-float.h: New file.

236 doubles and various target IEEE extendeds.
237 * m68k-xdep.c: Eliminate assembler code for extended floats.
238 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
239 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
240 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
241 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
242 double_to_ieee_extended.
243 * i960-tdep.c: Define ext_format_i960.
244 * m68k-tdep.c: Define ext_format_68881.
245 * sparc-tdep.c: Define ext_format_sparc, though unused.
246 * Makefile.dist (HFILES): Add ieee-float.h.
247 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
250 Obsolete the "coffstrip" program in favor of using BFD's strip.
252 * nindy-share/coffstrip.c: Remove file.
253 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
254 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
255 * tconfig/nindy960: Remove reference to coffstrip.o.
257 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
259 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
261 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
262 * dbxread.c: Remove static symfile_bfd.
263 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
265 * inftarg.c (child_detach): Pop the child_ops vector if the
266 detach is successful.
267 * remote-nindy.c (nindy_create_inferior): Don't push a new
268 nindy_ops since nindy uses the same one for execution and memory
270 * core.c (core_ops): Use child_attach and child_create_inferior
271 rather than default attach and create_inferior functions.
273 Handle floating point registers in core files.
275 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
276 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
277 This version untested since BFD doesn't yet support sun3 core
279 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
280 conventions. Fix comments and style. This version has not
281 been compiled yet, since we have no HP inhouse.
282 * core.c (get_core_registers): Look for two sections, ".reg"
283 and ".reg2", and pass both to fetch_core_registers sequentially.
285 Revise directory path yet again.
287 * source.c (forget_cached_source_info): Not static any more.
288 (init_source_path): New default source path is "$cdir:$cwd".
289 (dir_command): Handle variable arguments ($cdir, $cwd).
290 (source_info): Print "Compilation directory" rather than
291 "Originally compiled in" to remind people of $cdir.
292 (openp): If the path contains $cwd, use current directory.
293 (open_source_file): If compilation directory is known, replace
294 first $cdir in path with the compilation directory.
295 (print_source_lines): Even if we can't print the lines, set the
296 current symtab and line for future commands like "info source" or
297 "breakpoint". Also, error message now contains the file name,
298 line number, and file access error message.
299 (_initialize_source): Fix help text to describe changes.
300 * main.c (cd_command): Forget cached source info when we chdir.
301 * utils.c (strstr): Add simple implementation.
303 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
305 * coffread.c (read_one_sym, init_linetable, init_stringtab):
306 Byte-swap COFF symbol tables if necessary when reading them in.
307 Use complain() to replace error message in one spot. Needs
308 corresponding change in bfd/coff-code.h to make some symbol
309 swapping routines non-static.
311 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
313 Merge changes from Eirik Fuller, for UTek.

318 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
319 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
320 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
321 declarations of errno.
323 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
325 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
326 <rpc/rpc.h> and <rpc/types.h>.
328 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
330 * i960-tdep.c (examine_prologue): Add new argument limit,
331 which stops the scan at the end of the prologue, or at the PC.
332 This fixes a problem where it walks down into the code for the
333 user's statements if that code looks like function prologues.
334 Mark Fox and I have been bouncing this code back and forth, making
335 small changes to it. Callers changed to match.
337 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
339 Cleanup for gdb-3.94 release final:
341 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
342 the .c files from vx-share and nindy-share, from the various
343 macros, since they are not found via ALLDEPFILES.
344 (SFILES): Add tm-i960.h.
345 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
346 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
348 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
349 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
351 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
353 * am29k-tdep.c: Add contribution line.
354 (examine_prologue): Cache information about function prologues in
355 the misc-function-vector to avoid lots of references over the
356 serial line while examining instructions.
358 * core.c (core_close): New function made from cleanup_core.
360 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
361 remote-vx.c, remote.c, target.c, target.h,
362 Update target_ops vector to add attach, close, and load entries.
363 Use add_syms_addr_command, not add_file_addr_command, for
364 add_file. Break out close routine from existing code.
366 * dbxread.c (really_free_pendings): Don't free pending_blocks;
367 they are in an obstack.
368 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
370 (define_symbol): Add symbol type parameter; change callers;
371 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
372 it to influence the symbol class on the i960.
373 (define_symbol): Swap LOC_CONST's into target byte order.
375 * exec.c (exec_close): New function.
376 (exec_file_command): Call it.
378 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
379 Fix byte order of frame pointer.
380 (read_var_value): Result of 0 if var's value can't be found,
381 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
382 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
383 (locate_var_value): Use read_var_value and use its lazy address
384 as the location of the var's value. Lint.
386 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
389 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
390 obsolete Intel versions in favor of vxgdb versions.
391 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
392 code dealing with byte order of values, which Intel did in host byte
393 order rather than gdb-4's target byte order.
394 (i960_frame_chain_valid): Move to nindy-tdep.c.
395 (examine_prologue, skip_prologue, frame_find_saved_regs,
396 frame_args_address, leafproc_return, saved_pc_after_call,
397 pop_frame): Add vxgdb versions from Mark Fox.
398 (examine_prologue, frame_struct_result_address): Add code
399 to deal with the saved value of G13 (struct return address
401 (frame_args_address): Modify Mark's version to prefer the
402 saved value over the current value in the topmost frame.
403 Cache result in the frame info to avoid performance hair in
405 (print_fault): Add gdb960 code for printing faults.
406 (_initialize_i960): Actually call check_host.
408 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
409 add stub routines. FIXME, these currently just return zero!
411 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
412 (attach_command): Call target_attach, not target_open, now.
414 * infrun.c (normal_stop): Make global, not static, for vx_attach.
415 (child_attach): Rename from child_open.
416 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
417 don't confuse it with a zero step_resume_break_address.
419 * inftarg.c (child_detach): Eliminate inferior_pid test.
420 (child_files_info): Clean up message a bit.
421 (child_ops): Use child_attach, not child_open, to attach.
423 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
424 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
425 findvar.c to here, since it depends on the contents of the
426 shadow_contents of breakpoints, but keep if #if 0 since it is
429 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
432 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
433 (ptype_command, display_command): Eliminate have_inferior_p and
434 have_core_file_p in favor of target_has_stack or
435 target_has_execution.
436 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
437 code for actually finding the values of arguments, though we still
438 keep track of the maximum stack offset for use in printing unnamed
439 arguments. Handle missing FRAME_ARGS_ADDRESS.
441 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
442 (struct nindy_regs): Define registers passed to/from nindy.
443 (nindy_fetch_registers, nindy_store-registers): Translate between
444 nindy and GDB formats for the registers.
445 (dcache_init): Statically allocate the cache, since it was being
446 allocated by a malloc that was never freed anyway.
447 (nindy_create_inferior): Error, not core dump, if no exec file.
448 (nindy_before_main_loop): Use target_load, not target_add_file.
450 * remote-vx.c (net_load): Specify large timeout for load
451 requests. Allow user to break out with INTERRUPT.
452 (net_break): Remove useless code, clean up. Change callers.
453 (parse-args, skip_white_space, find_white_space): Clean up arg
454 parsing to cope with quoted strings.
455 (net_wait, net_quit): Never call error, just return status.
456 (vx_read_register, vx_write_register): Cleanup status checking.
457 #ifdef the code based on which CPU we are using (960 or 68k),
458 FIXME, this should be completely general but it isn't yet.
459 (vx_xfer_memory, vx_resume): Cleanup status checking.
460 (vx_run_files_info): Improve message.
461 (vx_load_command): Renamed from vx_add_file_command. Allow load
463 (net_ptrace): Remove unused routine.
464 (vx_wait): Adopt code from vxgdb960 to cope with broken
465 connections to target machine and prompt to disconnect. Remove
466 debug printouts. Map some EVENT_'s to SIGnals.
467 (add_symbol_stub, vx_open): Print names of object files we found,
468 and "ok" if we read their symbols OK. Clarify output in general.
469 (vx_attach, vx_detach, vx_kill): Add these commands.
470 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
471 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
472 "info files" output, and create_inferior, since we already have
475 * stack.c (frame_info): Replace Frame_unknown with 0.
476 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
477 (return_command): Pop until the PC matches as well as the FP,
478 so it works even if the FP is shared with another function,
479 as in "frameless" or "leaf" procedures.
481 * symfile.c (load_command): renamed from add_file_target_command.
482 (add_syms_addr_command): renamed from add_file_addr_command.
483 (add_syms_command): Stub to call target_add_syms.
484 (_initialize_symfile): Change command names and descriptions,
485 add-file => add-syms, and load from alias to its own command.
487 * target.c (kill_or_be_killed, maybe_kill_then_attach,
488 maybe_kill_then_create_inferior): Default for attempts to start
489 a process, if one is already running, is to ask about killing
491 (upstack_create_inferior): #if-0 it, strata obsolete it.
492 (push_target, unpush_target, pop_target): to_close() a target
493 before unstacking it.
494 (target_info): Renamed from target_files_info.
495 (_initialize_targets): Rename "i files" as "i target", accessible
498 * target.h: Improve comments about the target_ vectored routines.
500 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
501 Convert commenting style to standard GNU style.
502 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
503 (SKIP_PROLOGUE): No longer a no-op.
504 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
505 (*_REGNUM): Sort register numbers.
506 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
507 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
508 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
509 are now 10 byte extendeds, not 8 byte doubles.
510 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
511 for nindy versus vxworks targets. FIXME, this should possibly go
512 in the target vector.
513 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
514 frame_saved_regs and arg pointer with each frame.
515 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
516 (FRAME_ARGS_ADDRESS): Use cached result.
517 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
518 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
519 (PRINT_RAMDON_SIGNAL): Call print_fault.
520 (POP_FRAME): Now works.
522 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
523 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
524 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
525 (ADDITIONAL_OPTION_HANDLER): use target_load, not
528 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
529 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
531 * valarith.c (value_subscripted_rvalue): Avoid handling
532 floats and doubles specially; it gave alignment errors. Lint.
534 * valops.c (value_of_variable, value_of_this): Error if unknown
537 * valprint.c (print_floating): Bcopy rather than pointer-deref,
538 to avoid alignment problems.
539 (value_print): Handle unknown value address.
540 (cplus_val_print): Two args are ignored; remove them. Change caller.
541 (val_print): Use unpack_long rather than pointer-deref.
544 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
545 to avoid alignment problems.
546 (value_being_returned): Error if return value unknown.
547 (set_return_value): Add bogosity warning, FIXME. *
549 * TODO: A woman's work is never done.
551 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
552 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
553 Add ieee-float.o to OBS.
554 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
555 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
556 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
558 Changes to generalize the VxWorks RPC protocol slightly, to handle
559 i960 as well as 68000.
561 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
562 * vx-share/reg.h: Produce i960 regs #ifdef I80960
563 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
564 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
565 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
566 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
567 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
568 so they will move in target byte order rather than network
569 byte order (happens to be the same).
571 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
573 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
575 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
578 Add contribution lines to various files, showing where they
581 * breakpoint.c (break_insn, check_break_insn_size,
582 read_memory_nobpt): Remove to mem-break.c.
584 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
587 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
588 entry has bad register number. This change is not
589 tested in this release, FIXME.
591 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
594 * value.h: Force value's contents field to be aligned to hold
595 at least a double or a long long (if supported). This avoids
596 doing bcopy's in and out of the contents field.
598 (step_1): Avoid coredump under obscure circumstances when we
601 * symtab.h (misc_info): Add field to misc function vector for
602 any kind of cached information the target code desires. AMD
603 29000 uses this to avoid repeating examine_function_prologue's.
605 * coffread.c: Lint. Remove static symfile, read_section_header.
606 core.c (have_core_file_p): Lint: remove.
607 expprint.c (print_subexp): Lint.
608 infptrace.c, valops.c, valprint.c: lint.
610 Roll in changes from vxgdb-5.0.1:
612 * symtab.h: Comment byte order of each address class. Add
613 LOC_LOCAL_ARG for frame-relative args (960).
614 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
615 symtab.c, symmisc.c: ditto.
617 * infrun.c (init_wait_for_inferior): Clear stop_signal.
619 * remote.c (remote_resume): Error if resume with a signal.
621 * symfile.c (prim_record_misc_function): Clear misc_info.
622 (fill_in_vptr_fieldno): Check stub type of arg.
624 * valops.c (value_cast): Avoid looking up names of types whose
625 name we don't know, to prevent coredump. Sun CC produces typedef
626 rtx and the name of *rtx is zero...
628 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
630 Roll in changes from final AMD 29000 port (Tiemann).
632 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
633 for ../include/a.out.encap.h. This might not work now that BFD
634 is separately compiled. Instead, BFD support for encap will have
635 to translate machine type 29k into the right COFF_MAGIC.
637 * infcmd.c: Remove references to inferior_pid that aren't used
638 in actual ptrace calls; use target_has_execution, etc.
639 (have_inferior_p): Remove function.
640 (program_info): Print target info rather than "process number";
641 avoid gratuitous messages unless from_tty.
642 (run_stack_dummy, finish_command): Set proceed_to_finish.
643 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
644 main.c: Lint. Lose have_inferior_p().
645 inferior.h (have_inferior_p): Remove, lint.
646 (proceed_to_finish): Add flag to ask that all regs be saved
647 by normal_stop, for the few commands that need it, speeding up
648 serial I/O. Add comments to stop_registers.
650 * remote-eb.c: Remove newline from breakpoint message we grep
651 for. Never time out when running the user program.
655 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
657 Roll in changes from vxgdb-5.0.1:
659 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
660 symbol in its raw form, we are processing an unlinked ".o" file.
661 See if the target environment has assigned it an address, using
662 target_lookup_symbol (VxWorks does), and enter it into the symtab
665 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
666 68k versions for a simpler version that assumes zero FP at bottom.
667 Fixes bug of truncated stack reports.
669 * target.h (target_lookup_symbol): Define this routine's args
672 * target.c (nosymbol): Default routine for target_lookup_symbol.
673 (target_default): Default lookup_symbol and call_function too.
674 (files_info): Only print has_all_memory warning if a non-dummy
677 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
678 vx_convert_from_virtual): If target does not have floating point,
679 zero register "values", and avoid doing cross-net conversions.
680 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
681 (vx_open): Rearrange code that attaches to target and reads
682 symbols for all loaded modules, to work if some of the modules
683 are not accessible. Add symbol_stub() and add_symbol_stub()
684 as callbacks from catch_errors(). Allow connect attempt to be
685 interrupted painlessly with ^C (FIXME, there are still some bugs
686 if the interrupt happens during symbol reading.). Print
687 final message with puts_filtered, since symbol messages are
692 * main.c (catch_errors): Only print errstring if non-null.
693 (command_loop): Avoid an ioctl per command to test ISATTY.
695 * remote-vx.c (net_load): make static; avoid sophomoric msg.
696 (vx_xfer_memory): Return correct result!
697 (vx_files_info): Indicate whether target has float or not.
698 (vx_lookup_symbol): Complain, not error, if target gone.
699 (vx_open): Print "Connected" msg before disabling immediate-quit.
700 [FIXME: lookup_symbol and vx_open changes need testing.]
702 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
703 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
704 contributor lines and update copyrights to 1991.
706 Changes from an attempted H-PUX host port:
708 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
709 defines PT_ATTACH and PT_DETACH but not PT_KILL.
710 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
711 * remote-vx.c: include <sys/time.h> for HPUX.
712 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
713 "core_file_command" routine to BFD regime. May not work yet.
715 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
717 * xgdb.c: Replace X10 version with some VJ version.
718 (FIXME: Its copyright assignment is not on record.)
719 * xgdb.c: Update include files to X11R4 (Xaw crud).
720 (xgdb_display_source, create_text_widget): fix call to
721 get_filename_and_charpos. Rewack source window stuff for X11R4
722 (gleaned from include files, and "nm's" of binary libraries, since
723 I had no doc available).
724 (append_selection, append_selection_word): Disable with FIXME
725 since R4 changed interface here.
726 (create_buttons): Add back the old set of buttons.
727 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
729 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
730 Roll VERSION to 3.94 (not yet final though).
732 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
734 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
735 obstack_int_grow, obstack_int_grow_fast): Eliminate
736 cast on left of assignment, which gives MIPS cc fits and is
739 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
740 F_ALIAS. Use printf, not fprintf, when not passing a file
742 (compare_opcodes): Check that identical instructions have
743 identical opcodes, complain otherwise.
745 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
746 was reported by Roland McGrath.
747 (unimp): Only match if exactly zero instruction. (Roland)
748 (branches and traps): Generate all variations of these
749 instructions with macros, based on a single call that defines
750 each condition name and its binary representation.
751 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
753 * valprint.c (val_print_fields): Take, and use, format parameter.
754 This means that "p/x struct" again prints the elements in the
755 desired format. Changed callers.
757 * stack.c (frame_info): Use filtered output, and indicate wrap
758 points. Remove kludgy formatting designed to avoid line wrap.
760 * utils.c (wrap_here): If the line is already full (because
761 we had printed a long indent or long wrapped string), do an
762 immediate newline-and-indent.
764 * m68k-pinsn.c (print_insn_arg): Bugfix from
765 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
766 instruction is incorrectly disassembled as bkpt #8.
768 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
769 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
770 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
771 and then will dump core (sometimes). I traced it back to an
772 uninitialized symfile_name in psymtab_to_symtab.
773 (const_vol_complaint): Add quotes to message.
774 (define_symbol): Only believe line number if gcc_compiled.
775 Avoid allocating symbol if we will not return it.
777 Add target strata support so that newly established targets go
778 into their right place in the target stack (e.g. a new exec file
779 doesn't wipe out the ability to access the running process).
781 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
782 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
783 and initialize it properly in all the targets.
785 * target.h: Document strata. Change return type of push_target.
787 * target.c (nomemory): new function for dummy memory access.
788 (tcomplain): Rename complain, now also used in symfile.c.
789 (push_target): Push targets within strata. New return value shows
790 whether new target is on top of stack or not. Always keep dummy
792 (target_files_info): Ignore dummy target.
794 * core.c (core_open): Warn user, and skip accessing file, if the
795 core target is not the topmost target in the stack.
796 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
799 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
800 target_ops, it doesn't belong there since we have no regs there.
801 Change name of target from machine => memory to clarify.
803 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
805 * Freeze version 3.93 for release.
807 * Makefile.dist: Handle vx-share and nindy-share subdirs
808 properly when building gdb.tar.Z.
810 * symtab.c: lint; add no_symtab_msg to consolidate the messages
811 printed in various places, so I could change just one copy.
813 * dbxread.c, coffread.c: Change references to bfd->iostream
814 to cast to FILE *, now that BFD avoids needing types defined
815 in other header files.
817 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
819 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
820 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
821 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
822 (actually gcc -Wall).
824 * dbxread.c: Remove first_global_sym, last_global_sym, since
825 they are never referenced.
827 * defs.h (baud_rate): Declare.
828 main.c: Define it, and add the -b option to set it.
830 * gdb-int.texinfo: Add text on how to define a new host or target
831 architecture, prompted by Per Bothner's questions about MIPS
834 * gdb.texinfo: Document "complaints". Change doc of -q since
835 gdb no longer prints the copyright and blurb if you specify a file
836 name to be debugged (just like Emacs). Add doc for Nindy-specific
837 command line flags for specifying target serial port and such.
838 Update copyright to 1991.
840 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
841 has taken over for us the job of ripping up executable files. The
842 crud caused Per Bothner's port to not compile.
844 * infrun.c (normal_stop): Avoid printing "Program exited
845 normally" if we are in batch mode. This allows a GDB which
846 executes a program on a target system, to behave like a Unix
847 command (input from stdin, output to stdout, no extraneous
850 * main.c (main): Allow additional machine-dependent command line
851 options to be specified with the ADDITIONAL_OPTIONS,
852 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
853 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
854 processing to occur just before the main loop with
855 BEFORE_MAIN_LOOP_HOOK.
856 (main): If a "core file" argument is specified, and it is not a
857 core file, try it as a process ID to attach.
858 (symbol_completion_function): Attempt to cope with
859 "show screen-" TAB, not very successfully. This needs more work,
861 (batch_file): New function, returns whether we are reading
862 commands from an interactive tty on stdin, or from somewhere else.
863 Called by normal_stop since it doesn't get from_tty passed down
864 to it like many commands do.
866 * remote-nindy.c: Handle command line options for nindy
868 (nindy_before_main_loop): Prompt user for tty name if they
869 don't specify it before getting to the interactive command loop.
871 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
872 and -r command line options. Also add hook before main loop
873 to make it easy to specify a tty.
875 * TODO: More things to do, one done.
877 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
879 * dbxread.c: Make complaint() calls pass pointer, not struct.
880 Add complaints about badly formatted C++ type information
881 (const/volatile indicator, and parse errors resulting in
882 error_type). Fix C++ virtual member fn comment.
883 (read_struct_type): Avoid bumping pointer if we got a parse
884 error; this prevents our walking beyond the end of a string.
885 Terminate loop on null char as well as semicolon.
886 (process_one_symbol): Fix the LBRAC fix so that it uses the
887 last previous SLINE, FUN, or SO record's PC address. C++ debug
888 symbols did not have SLINE records in a useful order compared
889 to the LBRAC records.
890 (define_symbol): Handle "catch" records.
892 * symtab.c (check_stub_type): Added new complain
893 `stub_noname_complain' and added a consistency check to
894 keep the debugger from crashing when finishing from an
895 exception frame. A real fix will be needed later.
897 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
899 * infcmd.c (attach_command): Make global.
901 * Makefile.dist (REMOTE_OBS): Make these compile by default,
902 but make them easy to comment out. Perhaps later they should
903 be enabled by what CPU you configure for? FIXME.
904 (VERSION): Roll to 3.93.
905 (pinsn.o): Remove rule for obsolete file.
906 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
908 Run down a problem that manifested by printing the wrong function
909 name in stack traces of read_ofile_symtab. Turned out that the
910 problem was the SunOS 4.1.1 (and previous) C compiler outputs
911 the LBRAC symbol with an address in the *data* segment, which
912 blew our binary search through the blocks.
914 * dbxread.c: Use the complain() facility consistently to bitch
915 about problems in the symbol file we are reading.
916 (finish_block): Add code to check the nesting of the blocks;
917 complain and Procrust them to fit if wrong.
918 (make_blockvector): Check the order of the blocks, complain
919 [but don't cope] if wrong.
920 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
921 symbols to be sure their PC value is greater than the last SLINE
922 (line number) symbol we've seen, complaining and adopting the
923 SLINE PC value if wrong.
925 * symfile.h (struct complaint, complaint_root, complain,
926 clear_complaints): Add.
927 * symfile.c (complain, complaint_root, clear_complaints): Add
928 facility to deal with non-fatal complaints and to regularize their
930 (symbol_file_add): Clear complaint counters to allow new complaints.
931 (initialize_symfile): Add 'set complaints' and 'show complaints'.
933 * dbxread.c (dbx_symfile_read): Remember the address and size
934 of the string table for the main symbol file, so we won't read it
936 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
937 to avoid reading the string table yet again. Lint.
938 (throughout): Improve filtered output, including word wrap.
939 (read_range_type): Improve Bothner's fix to handle other types too.
941 * utils.c: Improve line wrap implementation. Handle unlimited
942 width by making chars_per_line unsigned.
943 (puts_filtered): New, easy, function.
945 * defs.h (puts_filtered): add.
947 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
948 call the identical sort_symtab_syms() in symfile.c instead.
950 * expread.y: Suggest the `file' command rather than `symbol-file'.
952 * command.h (enum var_types): Add zinteger for seroable
954 * command.c (do_setshow_command): Handle var_zinteger. Restructure
955 nested if's into a switch.
957 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
958 we did not stop because of a breakpoint (it must have been for
959 some other reason, like a "stepi"), so don't print anything.
961 * symtab.c: Include <sys/types.h> all the time. Now that BFD
962 doesn't include <sys/types.h>, old SunOS's require it for
965 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
967 A test port of gdb-3.92.6 to the Sony NEWS.
970 Don't normally link in remote- or vx stuff.
971 Some of it doesn't compile, and it wastes space for 99% of the users.
972 Remove reference to no-longer-used HAVE_VPRINTF.
973 Fixed BFD_DEP typo to BFD_DIR.
975 Fix cast in arg to bfd_h_getlong.
976 Make char *prefix be const.
977 Fix how certain range types are mapped into builtin unsigned int types.
979 Remove 2 #includes. They cause errors (on Sony, at least),
980 and aren't needed (they wern't in earlier versions).
982 print_address_symbolic should never demangle labels
983 (since it prints *assembler-level* labels).
985 [This was superseded by the change to printcmd below.]
988 Add some "volatile" return types to avoid warnings.
989 If MISSING_VPRINTF add vprintf function and not just macro
990 (since vprintf is used in printcmd.c).
992 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
993 (The latter isn't grokked by some PCC-based compilers.)
995 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
997 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
998 * nindy-share/coffstrip.c
999 Added some forward declarations (otherwise, gcc complains
1000 about implicit extern redefined as static).
1002 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1004 Changes inspired by Per Bothner:
1005 * printcmd.c (print_address_symbolic): Take additional parameter
1006 specifying whether to demangle.
1007 (print_address): Pass in asm_demangle to control demangling.
1008 (print_address_demangle): New fn, takes explicit arg to control
1010 * utils.c: Add new vars demangle and asm_demangle, and let them
1012 (fputs_demangled): If !demangle, just print the argument.
1013 (fprint_symbol): If !demangle, just print raw symbol.
1014 * valprint.c (val_print): Call print_address_demangle rather than
1015 print_address, to cause demangling to depend on the global
1016 rather than assembler-level demangling setting.
1017 * WHATS.NEW, gdb.texinfo: Document.
1019 * main.c (show_command): Show all settings if no arg.
1020 (initialize_main): Make "info set" the same as naked "show".
1021 * command.c (cmd_show_list): Handle prefix commands in the
1022 list, and print the name of the setting as well as its English
1023 description and value.
1025 Allow gdb functions to specify where a line should wrap if it
1026 exceeds the size of a terminal line. Use it to make the output
1028 * utils.c (set_screen_width_command): New fn, mallocs a buffer
1029 of the right size when screen width changes.
1030 (set_screensize_command, screensize_info): Remove #if 0'd fns.
1031 (wrap_here): New fn, indicates a point in the output where we
1032 should wrap the line rather than just letting it overflow at a
1034 (fputs_filtered): Implement wrapping.
1035 (n_spaces): New fn, returns a pointer to N spaces.
1036 (print_spaces_filtered): Use n_spaces.
1037 * defs.h (n_spaces): Declare.
1038 * stack.c (print_frame_info): Wrap with 4-space indent after
1039 fn name and before filename and line number.
1040 * printcmd.c (print_frame_args): Wrap with 4-space indent
1041 before each argument name is printed.
1042 * valprint.c (value_print): Wrap with no indentation before
1044 (val_print_fields): Wrap with indentation relative to nesting
1045 level before each field name.
1046 (val_print): Wrap with nesting indentation before array elements.
1047 * command.c (do_setshow_command): Avoid extra newlines,
1048 wrap with 4-space indent around values printed, end with period.
1049 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
1051 * breakpoint.c (breakpoint_1): Implement addressprint for
1052 "info breakpoints" display. Change file name and line number
1053 format to " at file:nnn" rather than " (file line nnn)".
1054 * gdb.texinfo: Document.
1057 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1059 Frozen for gdb-3.92.6 release.
1061 README, WHATS.NEW: Update for 3.92.6 release.
1063 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
1064 coffread.o from configs since it is now built by default.
1065 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
1066 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
1067 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
1068 from configs since it is now built by default.
1070 Makefile.dist: Update for release 3.92.6. Handle files that
1071 have been moved to ../include, ../getopt, or ../bfd. Add
1072 saber.suppress and tests directory. Add config.status to
1073 the release (it will say "none").
1075 coredep.c: Minor formatting fixes.
1077 These changes were made in early December but only checked in now:
1078 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
1079 nindy-share/nindy.c: lint
1080 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
1081 register values coming back from the target; we store values
1082 in target byte order everywhere.
1084 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
1086 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
1088 * valprint.c (cplus_val_print, val_print_fields): New functions,
1089 which print C++ objects. They conspire to avoid printing a
1090 virtual base class more than once, following all the twists and
1091 turns of C++ virtual base rules.
1092 (val_print): Call the above rather than do it by hand.
1094 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
1095 symbol file, not for added files like shared libs. This really
1096 needs to be generalized to a timestamp per file.
1098 * core.c (cleanup_core): Avoid coredump if no core file.
1100 * config.gdb: Accept -host or -target in place of +host or
1103 * coffread.c (find_linenos): Avoid desupported BFD interface
1104 to line numbers. We still read them manually rather than using
1105 BFD's "generic" features.
1107 * gdbrc.tex, threecol.tex: Add GDB reference card and its
1109 Makefile.dist: Add refcard to OTHERS list for creating tar files.
1111 * Makefile.dist: Eliminate use of $< in explicit targets.
1113 * readline/Makefile: Use $< rather than $*.c, which does not
1114 include the VPATH in GNU Make.
1116 * tconfig/i960-bout, tconfig/i960-coff: These are identical
1117 copies of tconfig/i960, added for global configuration
1118 compatability. All i960 versions can read both coff and b.out.
1120 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
1121 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
1124 * TODO: Think of more things to do.
1126 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
1128 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
1129 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
1130 64-bit float conversion.
1132 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
1133 equivalent to sun?os4 so global config works.
1135 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
1137 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
1139 * main.c: Only declare linesize once; declare pagesize not at
1140 all, since it is never used.
1141 (main): Clear newly allocated line before it is used.
1143 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
1145 Further stabilization for the Intel 960.
1147 * Makefile.dist: Parameterize the location of the "include"
1148 and "bfd" directories, as well as "getopt". Add symfile.c.
1149 Link in both dbxread and coffread. Fix up "make depend" to
1150 rewack the locations of include, bfd, and getopt in its output.
1152 * README: Document moving include files, improve some of
1155 * coffread.c: Move common code out to symfile.c. Change
1156 symbol_file_command style interface to use new *_symfile_init
1157 and *_symfile_read interface under BFD. Use BFD internal
1158 info to locate line table, symbols, etc.
1160 * core.c (core_fetch_registers): Rename to get_core_registers
1161 to avoid confusion with fetch_core_registers.
1162 (register_addr): Move to coredep.c, which is already machine
1163 dependent. This leaves core.c pretty clean of dependencies.
1165 * coredep.c (register_addr): Accept this routine from core.c.
1167 * dbxread.c: Move common code (with coffread.c, etc) into new
1168 symfile.c. Each psymtab now contains a pointer to the
1169 format-dependent function that knows how to read it in. Make
1171 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
1172 (process_one_symbol): Add code to complain about a "compiler bug
1173 we muzzle here", if we actually see it.
1175 * eval.c (evaluate_subexp): Insert missing "break" statements
1176 in code that determines whether a variable is an lvalue in
1177 memory, register, or whatever. I detected this via a compiler
1178 bug in which it *almost* mashed out the whole switch statement.
1180 * gdb-int.texinfo: Add minor sections on configuring gdb for
1181 release, and about the README file.
1183 * infcmd.c (registers_info): Fix formatting somewhat. Still
1184 not as pretty as before, but it handles byte swapping.
1186 * remote-nindy.c: If data cache routines are interrupted while
1187 waiting for the remote end, be sure that any uninitialized cache
1188 blocks are on the free list, not on the valid list!
1190 * symfile.h: Flesh out this header file with all the various
1191 routines and variables that have been merged in from dbxread.c
1192 coffread.c, and symtab.c to symfile.c.
1194 * symfile.c: New file, containing code common to dbxread.c,
1195 coffread.c, and some code from symtab.c. All generic code for
1196 reading symbol files should be in here now.
1197 (unrecord_misc_function): Remove unused function.
1199 * symtab.h: Remove file-reading things to symfile.h.
1201 * symtab.c: Remove file-reading things to symfile.c.
1203 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
1204 to decode i960 fault types.
1206 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
1207 target.c: Change type of the "resume" function from int to void,
1208 since its result was never used.
1210 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
1212 * main.c: Replace "stupid" with "caution"; you now "set caution
1215 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
1217 * infcmd.c (do_registers_info): Call val_print to deal with the
1218 byte order of the registers being printed. FIXME, this makes
1219 the formatting of the output uglier.
1221 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
1222 defined, call it for signals the debugger doesn't itself use.
1223 The i960 uses this for more detailed fault information.
1225 * remote.c (remote_open): If arg is null, print help rather than
1228 * sparc-xdep.c (register_valid): Avoid declaring size, since
1229 various modules will think of various sizes depending on the
1230 architecture of their tm-file. FIXME, we need protection against
1231 actually entering one of those modules, which would clobber
1232 storage if not for the target architecture compiled into gdb.
1234 * stack.c (up_command, down_command): Always print the frame
1236 (up_silently_command, down_silently_command): New commands
1239 * i960-pinsn.c (reg), i960-tdep.c: Lint.
1241 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
1242 more parameters than it used to.
1244 * findvar.c (registers): Increase slop to 256 bytes, which should
1245 protect us against even most RISC machines with large register
1247 (locate_var_value): Move declaration inside related ifdef.
1249 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
1250 throughout, to avoid throwing away buffered input from the board.
1251 (nindy_wait): Supply_register takes addr_of_value, not value.
1252 (i960_print_fault): Renamed from i80960_fault.
1253 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
1254 (nindy_store_registers): Avoid regs_changed stuff, just stuff
1256 (nindy_create_inferior): Don't bother to write PC_REGNUM since
1257 we can set the PC in the call to proceed(). Unpush nindy_ops
1258 before pushing it on top, to avoid message to user. Eliminate
1259 commentary from Unix machines that just misleads here.
1260 (reset_command): Fix error message to suggest target command.
1262 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
1264 Release 3.92.5 as frozen.
1266 Stabilize the merged release...with help from lint, Saber C,
1269 Everywhere: Add include files needed to declare return types
1270 of functions called.
1272 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
1274 * breakpoint.h: Add undeclared breakpoint functions, and some
1275 functions for display handling since I couldn't think of a better
1278 * breakpoint.c (insert_breakpoints): Make code for disabling
1279 shared library bkpts more likely to work. It's used when we
1280 rerun a program and stop before the shared library has been
1282 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
1283 cast from pointer, so it squeezes through catch_errors.
1284 (bpstat_stop_status): Fix logic broken some time ago. We now
1285 always create a bpstat if the stop address matches a breakpoint,
1286 even if we don't stop there -- just like the old code used to do
1287 before I got my fingers into it (sigh).
1288 (breakpoint_1): Print "ignore count" after "stop only if"
1289 condition, since that's how it actually works.
1290 (mention): Handle watchpoints as well as breakpoints.
1291 (watch_command): use set_raw_breakpoint and mention to do most
1292 of the work (and initialize all the fields!). Only pass one
1293 arg to parse_c_expression, since that's all it takes.
1295 * command.c (not_just_help_class_command): Rename arg to args
1296 since we ignore "unused argument" warnings on vars named "args".
1297 inflow.c (child_terminal_info): ditto.
1298 infptrace.c (kill_inferior): ditto
1299 main.c (catch_errors, version_info, quit_command, pwd_command,
1300 source_command, dump_me_command, editing_info,
1301 set_history_size_command, set_history, show_history,
1303 stack.c (locals_info): ditto
1304 target.c (target_files_info): ditto
1305 valprint.c (set_input_radix, set_output_radix): ditto
1307 * core.c: Remove old variables for handling core and exec file
1308 sections (data_start, data_end, stack_start, stack_end,
1309 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
1310 text_end, exec_data_start, exec_data_end, text_offset,
1311 exec_data_offset, data_offset, stack_offset). They're
1312 superseded the more general build_section_table and
1314 (get_exec_file): Mention the `file' command.
1315 (read_memory_check): Rename to memory_error, and only call it
1316 in the case of an actual error.
1317 (read_memory, write_memory): call memory_error.
1318 (core_fetch_registers): Register section name is ".reg".
1320 coredep.c: Remove a bunch of crud now that all this file does
1321 is pull the registers out of a core file.
1322 (fetch_core_registers): Rewrite to actually work, I hope.
1324 dbxread.c: Use a.out.gnu.h, not system a.out, now.
1325 Replace index() with strchr(). Remove all the pre-BFD macro
1326 definitions for accessing the symbol file.
1327 (struct dbx_symfile_info): Encapsulate the information that
1328 dbx_symfile_init needs to pass to dbx_symfile_read in this
1331 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
1332 dbx_symfile_discard): Rearrange symbol file reading to divide
1333 the format-specific part from the format-independent part,
1334 leaving the format-independent part such as file name expansion
1335 and opening in symtab.c. This replaces
1336 partial_symbol_file_open and partial_symbol_file_read.
1337 Symbol_file_read, add_file, add_file_target_command,
1338 add_file_addr_command move to symtab.c. Pass an explicit
1339 "mainline" flag for when reading the main symbol table, rather
1340 than relying on the offset address to be zero or nonzero.
1342 (dbx_symfile_read): Don't allow void *'s to be printed as
1344 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
1345 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
1346 macro" debug version really work.
1347 (read_dbx_symtab): Remove unref'd parameter inclink.
1348 Avoid swapping N_SLINE symbols, for speed.
1349 Merge N_TEXT!N_EXT case with the other external symbol
1350 definitions' case. Add comments.
1351 (start_psymtab): Allocate the symfile name in the psymtab on
1352 the psymbol_obstack, rather than using the caller's storage.
1353 (end_psymtab): Only allocate a dependencies list if there are
1355 (psymtab_to_symtab_2): Use BFD when reopening file to read
1356 its symbols for real.
1357 (read_struct_type): Add FIXME comments where it needs work
1359 (read_huge_number): Add FIXME about overflows.
1360 (read_range_type): Add FIXME about comparing a long to 1<<32.
1362 * coffread.c: Minor changes to move things closer to the new
1363 regime with symtab.c and dbxread.c Major work is still needed
1366 * exec.c (exec_file_command): Remove old variables (see core.c
1368 (xfer_memory): If memory transfer is right at the end of a
1369 section, don't lose.
1371 * findvar.c (get_saved_register): If value is in a real
1372 register, LVAL is lval_register, not lval_memory.
1374 frame.h: Declare print_sel_frame and record_selected_frame.
1376 gdb-int.texinfo: New file, for GDB internals documentation.
1377 Very simple, unformatted doc of cleanups is there for now.
1379 gdbcore.h: Remove obsolete variables that described a.out
1380 section addresses and offsets. (See core.c above.)
1381 Declare fetch_core_registers and registers_fetched.
1383 getopt.c: Declare char *alloca(); even on SPARC.
1385 infcmd.c (run_command): Call target_kill rather than
1387 (step_command, next_command, stepi_command, nexti_command):
1388 Declare from_tty parameter even though we don't use it.
1389 (run_stack_dummy): argument BUFFER is a char array, not
1390 a pointer to REGISTER_TYPE.
1391 (finish_command): using_struct_return needed a value *,
1392 not a struct symbol *.
1394 * infptrace.c (child_xfer_memory): To avoid dependency on
1395 where sections are in memory, try PT_WRITE_D and if that fails,
1396 try PT_WRITE_I. Most Unixes don't care which you use.
1398 * infrun.c (step_resume_break_shadow): Change to array to
1399 match other breakpoint shadow storage.
1400 (clear_proceed_status): Pass address of bpstat to
1401 bpstat_clear, not the bpstat itself.
1402 (child_create_inferior): FIXME comment about if the child
1404 (start_inferior): Remove old function.
1405 (child_open): Use target_kill rather than kill_inferior.
1406 (wait_for_inferior): Ditto.
1407 (insert_step_breakpoint, remote_step_breakpoint): Use
1408 new step_resume_break_shadow.
1410 * inftarg.c (child_wait): If all child processes die,
1411 pretend that the one being waited for exited with signal 42.
1413 * main.c (command_line_input): When scanning for comments,
1414 don't coredump on unclosed quotes.
1415 (quit_command): Use target_kill rther than kill_inferior.
1416 (_initialize_main): Rename class_user from "user" to
1419 * printcmd.c (print_command_1): Initialize "fmt" if no format
1420 is specified by the user.
1421 (print_frame_args): Only add to args_printed if we are
1422 actually fetching args from the stack (avoiding undefined
1424 (_initialize_printcmd): Remove bogus \{ from string.
1426 * remote-eb.c (eb_open): Avoid coredump on no argument.
1428 * remote-nindy.c: Bring out of Intel environment into new
1429 target environment. Remove all conditional compilation on
1430 I80960. Massive hacking throughout.
1431 (nindy_xfer_inferior_memory): New routine stolen from
1433 (nindy_create_inferior): New routine pieced together, probably
1434 not quite working yet.
1435 (nindy_ops): New target_ops struct for nindy.
1437 * remote-vx.c: Use write_memory rather than target_write_memory
1438 to get error checking.
1439 (vx_add_file_command, vx_open): Use symbol_file_add rather than
1441 (vx_create_inferior): Use target_terminal_ours...
1443 * signame.c (_initialize_signame): Always initialize, since
1444 we need the table for things other than psignal.
1446 * solib.c (solib_add): Use symbol_file_add, not add_file.
1447 (solib_address): Return boolean result rather than struct
1448 pointer which nobody else knows the type of.
1450 * sparc-tdep.c, valops.c: Use write_memory rather than
1451 target_write_memory, to get error checking.
1453 * stack.c (locals_info, catch_info, args_info,
1454 get_selected_block, frame_command, up_command): Use
1455 target_has_stack, rather than have_inferior_p or
1458 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
1460 * symfile.h: New file, defining the interface between the
1461 generic and object-file-specific symbol reading code.
1463 * symtab.c: Move generic symbol-reading interface to symtab.c,
1464 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
1465 table to map BFD targets to symbol-reading modules in GDB.
1466 Change index to strchr.
1467 (lookup_struct_elt_type): Use error() rather than hand-made
1468 simulations thereof.
1469 (lookup_partial_symbol): Speedup slightly when length == 0.
1470 (symbol_file_add): New function.
1471 (symbol_file_command): Call it.
1472 (symfile_open, symfile_init): New function.
1473 (add_file_target_command, add_file_addr_command): moved from
1476 * target.c (target_command): use target_kill.
1478 * target.h (target_files_info): Don't declare, never called
1481 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
1482 files to determine stack end address.
1484 * valarith.c (value_x_binop, value_x_unop): Change error message
1485 to be more useful. Pass proper argument to value_struct_elt.
1487 * valops.c (value_assign): FIXME comment that long long
1488 bitfields will break here.
1490 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
1491 Update `make saber_gdb' to work better.
1493 * TODO: A woman's work is never done.
1495 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
1496 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
1497 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
1498 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
1499 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
1500 valops.c, valprint.c, exec.c: Lint.
1503 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
1505 Continuing Intel 960 port merge of GDB.
1507 * Makefile.dist: Merge i960 "nindy-share" files. Rename
1508 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
1509 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
1510 Wack over "make depend" so it handles files in subdirectories
1511 vx-share, nindy-share, bfd, and in the current directory.
1513 * blockframe.c (get_prev_frame_info): Remove fatal error
1514 if stack not defined.
1516 * core.c (core_open, core_detach): New functions that handle
1517 the old "core-file" command as "target core" and "detach" instead.
1518 (core_file_command): Call them.
1519 (core_xfer_memory): Use common routine xfer_memory.
1521 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
1522 dbxread now uses bfd for everything but symbol reading itself.
1523 BFD internals are used to drag out the relevant file offsets.
1524 (partial_symbol_file_open): Change args all around for BFD.
1526 * symtab.c: Rename "value" to "val" everywhere, so we can
1528 (symbol_file_command): New command, moved from dbxread.c
1529 and coffread.c. It uses BFD to read the file, then vectors
1530 based on its type, to dbx or coff symbol readers.
1531 * symtab.h: Extern a few vars for symbol_file_command.
1533 * target.h: Breakpoint takes a char * save area, not a char **.
1535 * valprint.c (val_print): When unpacking bitfields, offset
1536 the address in gdb of the value, if it is declared with a shorter
1537 type. Remove the last "runtime kludge test" of host byte order.
1539 * utils.c: Remove old my_bfd_read routine.
1541 * stack.c (frame_info): Use target_has_stack. Print program counter
1542 register's actual name rather than "pc", since it's called the
1543 "ip" (instruction pointer) on the i960 (sigh).
1545 * target.c (target_command): Add command for selecting a target
1546 type and calling its open routine. This is used for initiating
1547 communication with a particular target, in a generic way.
1549 * tm-i960.h: Update for modern gdb. Remove semicolons from
1550 various macros. Handle reading struct return convention, and
1551 error-out attempts to return structs with the "return" command.
1552 Be sure gdb doesn't think we know how to call functions in the
1555 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
1556 to i960_xxx in lower case.
1557 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
1558 not being defined yet.
1560 * remote.c (remote_open): Call start_remote to initialize
1561 wait_for_inferior during open.
1562 (remote_xfer_inferior_memory): Return length written rather
1565 * remote-vx.c (target_command -> vx_open): Use new generic
1567 * remote-eb.c, inftarg.c, exec.c: ditto.
1569 * infrun.c: Fix comments.
1570 (attach_program -> child_open): Use new generic target command.
1571 (wait_for_inferior): Clear saved register values before target_wait,
1572 so target_wait can set some of them if convenient.
1574 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
1575 Return success indicator, not void.
1576 (child_xfer_memory): Avoid fetching initial word if we'll
1577 overwrite it anyway.
1579 * infcmd.c (attach_command): Use new generic target open routine.
1580 (_initialize_infcmd): Update doc on attach and detach commands.
1581 (do_registers_info): Merge in a byte-order problem as a FIXME
1584 * findvar.c (find_saved_register): Avoid problem in current frame.
1585 (read_relative_register): Ditto.
1586 (write_register): Convert byte order on the way out.
1588 * exec.c (file_command): Add.
1589 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
1590 (xfer_memory): Common function between core_xfer_memory and
1592 (exec_xfer_memory): Use it.
1594 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
1596 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
1597 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
1598 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
1600 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
1602 Merge Intel 960 port of gdb, continuing...
1604 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
1605 symbol_file_command): Pass from_tty arg to hush 'em up.
1607 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
1608 Add magic numbers for 960 COFF format.
1610 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
1612 Merge Intel 960 port of gdb, from Intel "1.2" release.

1633 Fri Apr 20 13:47:15 PDT 1990
1636 Thu Apr 19 09:54:28 PDT 1990
1637 Add 'reset' command.
1639 Wed Apr 18 09:48:07 PDT 1990
1640 After opening remote tty, wait for 1 second to go by without input
1641 from it before trying to talk to NINDY (fixes problems with the
1642 Heurikon HK80/V960E).
1644 Mon Apr 4 16:33:05 PDT 1990
1645 Some output was not being suppressed in 'batch' mode.
1647 Thu Mar 22 15:31:11 PST 1990
1648 Ask user if old symbol table should be deleted when new file is
1651 Allow user to run a program downloaded before gdb960 was brought up.
1653 Correct "exec-file" help message for i80960 context.

1675 Mon Oct 16 14:15:09 PDT 1989
1676 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
1678 Mon Oct 2 15:56:31 PDT 1989
1680 Added 960CA disassembly support.
1682 To simplify maintenance:
1683 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
1685 - eliminated opcode.h: incorporates tables into i960-pinsn.c
1686 - moved 960-specific routines from i960-pinsn.c to i960-md.c
1687 - made disassembly interface identical to that in gdmp960.
1691 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
1693 * target.h: Allow targets to stack. Add target_has_memory,
1694 _registers, etc. Restructure memory access and "info files"
1695 to walk the target stack.
1696 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
1697 target.c: Change tables to match target.h.
1698 * inflow.c (child_mourn_inferior): pop child_ops.
1699 (generic_mourn_inferior): Use new has_stack flag.
1700 * infptrace.c (child_xfer_memory): New memory regime.
1701 * inftarg.c (child_files_info): New "info files" regime.
1702 * remote-eb.c: New memory regime, new info files.
1703 * remote-vx.c: New memory regime, new info files. Now use
1704 separate targets for VxWorks attachment to machine, and
1705 actually running a process under VxWorks, since one has
1706 stack & execution & regs and the other doesn't.
1707 * remote.c: New memory regime, new info files.
1708 * sparc-xdep.c (fetch_core-registers): New memory regime.
1709 * target.c: New routines and support for stacked targets,
1710 new memory regime, new info files regime.
1713 Generalize section handling for an arbitrary number of sections,
1714 including use of the new BFD (binary file) library.
1715 * gdbcore.h: Add struct section_table.
1716 * exec.c (build_section_table): Iterate all sections and
1717 record what gdb needs to know about them.
1718 (exec_command): Use it.
1719 (exec_xfer_memory): Use the table.
1720 (exec_files_info): Print the table.
1721 * core.c (core_file_command, core_xfer_memory, core_files_info):
1723 * source.c (find_source_lines): Use bfd_get_mtime.
1724 * dbxread.c: Quick changes to make it compile with new BFD.
1725 * utils.c (error): Avoid using bfd_error in generic routines.
1727 * core.c (core_fetch_registers): Get from the ".regs" section of
1729 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
1731 * inferior.h (attach_flag): Export.
1732 * infcmd.c (run_command): use new target_create_inferior.
1733 * infrun.c (child_create_inferior): Don't return result.
1734 * Makefile.dist (VERSION): 3.91.4.
1736 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
1738 * breakpoint.c (bpstat_num): Handle breakpoints which have
1739 since been deleted, such as temporary breakpoints.
1740 infcmd.c (program_info): ditto.
1742 * core.c (core_file_command): Display the frame where the core
1747 * remote-vx.c (target_command): Merge in target command from
1748 targ-vx.c. A few other cleanups.
1750 * TODO, Projects: Lots more stuff to do...
1752 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
1754 Massive changes to wall off the remote-debugging interface
1755 behind a function vector. The port to handle VxWorks targets
1756 is also part of this.
1758 All files: Replace references to renamed functions,
1759 remove references to remote_debugging, remove references to
1760 have_include_file, have_core_file in favor of target_has_stack,
1761 target_has_memory, etc.
1763 * Modularize the breakpoint interface.
1764 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
1765 a breakpoint instruction.
1766 breakpoint.c: struct breakpoint's shadow_contents now sized as
1768 (insert_breakpoints): Vector to target to install breakpoints.
1769 (remove_breakpoints): Vector to target here too.
1770 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
1771 sparc-tdep.c (single_step): Use new breakpoint interface for
1772 the single-step breakpoints.
1773 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
1774 New file, contains routines to insert and remove breakpoints by
1775 reading out the old contents and later replacing them. This is
1776 how ptrace breakpoints work, and many remote systems as well.
1778 * tm-vxworks68.h: New config file, overrides a few things for
1779 Wind River's preferences.
1781 * target.h: New file, for transfer vector used to talk to the
1782 inferior (child, attached, core, exec, remote, etc). All accesses
1783 to the thing being debugged should come through these vectors.
1784 target.c: New file, routines to handle transfer vector.
1785 (various files): Add transfer vectors XXX_ops for the various
1786 targets and pseudo-targets (core files, etc) we support.
1788 * breakpoint.c (bpstat_stop_status): Further explorations of
1789 watchpoints and why things don't work all the time.
1790 (bpstat_alloc): New fn to allocate a bpstat and chain it.
1792 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
1793 the local gdbinit if it doesn't already have it.
1795 * core.c (core_ops): add and install.
1796 Allow core debugging without exec file.
1798 * dbxread.c (free_and_init_header_files): Merge two fns.
1799 (end_symtab): Free named symbol table when a new version comes in.
1800 (read_dbx_symtab): Relocate all kinds of symbols with base
1801 address. First step toward handling different text, data, bss
1803 (add_file_addr_command): Renamed add_file_command.
1804 (add_file_command): Vector to remote handler.
1805 Add "load" as an alias for "add-file" command.
1807 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
1808 non-returning functions.
1810 * exec.c: Add exec_ops, and push it as a target when an exec
1813 * infcmd.c (run_command): Pass executable file name and arg list
1814 separately when starting an inferior. Permit "run" when no exec
1815 file is specified, for VxWorks.
1816 (detach_command): Move to child_detach in inftarg.c.
1818 * inftarg.c: New file. Unix-child-specific routines, and the
1819 child_ops structure.
1821 * inferior.h (registers): Export "registers" as the way for
1822 target dependent register handlers to find gdb's local copy of
1823 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
1824 since it is now used by places that want wait_for_inferior to
1825 handle the grunge but want to see every trap from the inferior.
1827 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
1828 Eliminate remote_debugging hooks in terminal handling.
1830 * infrun.c: Replace start_inferior with child_create_inferior.
1831 Move all the hair of Unix shells and ptrace idiosyncracies into
1832 child_create_inferior, so remote handlers don't have to deal.
1833 Remove running_in_shell. Rename stop_after_attach to
1834 stop_soon_quietly, and use it in a few other places where we want
1835 to just call wait_for_inferior and get control back on the first
1836 trap. trap_expected now never takes a value > 1.
1837 (init_wait_for_inferior): Initialize static vars when a new
1840 main.c (gdbinit): Add new hook for .gdbinit file name, let
1841 it be overridden by config files as GDBINIT_FILENAME.
1842 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
1843 Both of these are used for VxWorks gdb.
1845 mcheck.c: rename include file "gmalloc.c" to avoid problems
1846 with system include file "malloc.c".
1848 param-no-tm.h: New include file, same as param.h but does not
1849 include the default "tm.h" file. This is used in files where
1850 the target is known, e.g. remote-eb.c or sparc-xdep.c.
1852 param.h: Now just a shell that includes tm.h and param-no-tm.h.
1854 remote-vx.c: New file, VxWorks remote debugging support. Uses
1855 RPC routines that are shared with the target system, in directory
1858 remote.c: Vectorize remote interface.
1860 source.c: Globalize source_path, and make an alias "l" for "list"
1861 since we now have the "load" command.
1863 sparc-xdep.c: Use new param-no-tm.h.
1865 symmisc.c (free_named_symtab): Add new function from Wind River.
1866 However, ifdef it out for now while we think about what it should
1869 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
1871 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
1872 non-Unix-children handle this with their own code in the target
1875 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
1876 source and target lists. Add vx-share to default list of include
1877 directories. Add new files to src and target lists: mem-break,
1878 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
1879 ${srcdir} versions of munch and createtags are used.
1881 * valops.c (find_function_addr): Split out of call_function.
1882 (call_function_by_hand): Rename call_function; this function
1883 calls functions in the target by laboriously patching the target
1884 word-by-word with the right stack, args, regs, etc.
1887 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
1889 Handle AMD 29000 a bit better.
1891 * remote-eb.c (readchar): Mask received char log to make it readable.
1892 (remote_start): Pass arguments down to executing program.
1893 Make startaddr unsigned.
1894 infrun.c (start_inferior): Accept args, pass them to
1896 infcmd.c (run_command): Pass args down to start_inferior.
1898 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
1899 the target object file format.
1900 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
1902 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
1903 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
1905 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
1907 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
1908 * TODO: We did a few things, we have more to do though.

1917 (sparc_push_dummy_frame): Simplify and fix what we push.
1918 (sparc_pop_frame): Slightly more hair here, deciding whether
1919 we are restoring a saved PC or returning to a return address in %i7.
1920 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
1922 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
1923 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
1924 * obstack.h (chunkfun): ditto.
1925 * defs.h (xmalloc, xrealloc): ditto
1927 * utils.c (quit): Grab the terminal from the child if necessary.
1929 * inflow.c (term_status_command): Rename to term_info, change
1932 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
1933 (is_delayed_branch): Speed up.
1934 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
1935 Still missing some float ops, and needs testing.
1937 * Support for input and output radixes other than base 10
1938 * defs.h (input_radix, output_radix): Declare.
1939 * expread.y (yyparse, parse_number): Handle changes of input
1940 radix, and ambiguous names-or-numbers in radixes >10.
1941 * printcmd.c (print_scalar_formatted): Print formatted hex
1942 numbers in varying column widths.
1943 * valprint.c (val_print): Use output_format to print scalar ints.
1944 (set_input_radix, set_output_radix, set_radix): Create.
1945 (set_output_radix): Set output_format from output_radix.
1946 (_initialize_valprint): add `set radix' but leave the others off.
1948 * main.c (execute_command): Let stupid questions be turned off.
1949 (_initialize_main): Handle "set stupidity", etc.
1951 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
1952 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
1954 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
1956 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
1957 bfd stuff is still screwed up, but with some manual work, it
1960 * breakpoint.c (bpstat_do_actions): Start over if a command
1961 proceeds the inferior, since the inferior will have stopped and
1962 will need to have its new stop-actions taken care of.
1964 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
1965 compiler fits, simplify it.
1967 * gdb.texinfo (directory command): Doc new dir command.
1968 source.c (directory_command): "dir" now puts things on the front
1969 of the path, moves dups up front, and handles multiple names
1970 on the command line, inserting each one in order. It also
1971 blows away cached line and full_filename info.
1973 * stack.c (backtrace_command): Skip "more stack frames follow"
1976 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
1977 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1978 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
1979 The only odd one was Gould NP1, which had defined vprintf to
1982 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
1983 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
1984 variable, inspect_it.
1985 valprint.c (print_string, val_print): Use the global inspect_it
1986 to indicate whether to print in Epoch style or normal style.
1988 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
1990 * printcmd.c (call_command): add an alias for the "print" command
1991 which runs expressions and doesn't print the result if void.
1992 (print_command_1): implement it.
1994 * command.c: Remove #if 0'd code. Initialize all the fields
1995 in add_cmd (). Rename do_nothing_command to
1996 not_just_help_class_command, and make it externally visible.
1997 command.h: add user_commands to struct.
1998 * main.c (define_command): Don't overload c->function with a char
1999 string as well as a function pointer.
2001 * eval.c (evaluate_subexp): Reinstall tiemann changes to
2002 calling convention of value_struct_elt () that got dropped in
2005 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
2006 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
2008 * tm-sparc.h (POP_FRAME): replace some constants with defines.
2010 * sparc-xdep.c (store_inferior_registers): defer stores to regs
2011 until a good time (e.g. when we are about to run the child),
2012 saving ptrace calls.
2013 * infrun.c (proceed): handle DO_DEFERRED_STORES.
2014 * tm-sparc.h: define DO_DEFERRED_STORES.
2016 * sparc-xdep.c (store_inferior_registers): when storing float
2017 registers, don't store stack regs too. When storing the SP,
2018 however, DO store the stack regs too. This fixes a bug in which
2019 the dummy frame is not recognized when a call_function finishes,
2020 because its frame pointer (in the stack regs) was never
2022 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
2023 even though we don't know how to read them from an inferior.
2024 valops.c (call_function): Comment about storing SP.
2026 * infrun.c (save_inferior_status): Save away the original bpstat
2027 chain so it can be restored later. Install the copied version for
2028 use by whoever saved the status. It will be blow away by
2029 restore_inferior_status, and the original chain restored. This is
2030 important for people who have pointers into the original.
2032 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
2033 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
2034 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
2037 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
2039 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
2040 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
2041 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
2043 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
2045 * Merge Mike Tiemann's multiple inheritance changes from Sun.
2046 Store the baseclasses in a type struct starting from array element
2047 0 rather than from the unusual array element 1.
2049 dbxread.c: the above.
2050 (virtual_context): Add
2051 Read new debug information about which virtual function table
2052 a virtual function is from, and store it in fn_field.fcontext.
2054 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
2055 TYPE_FN_FIELD_STATIC_P.
2057 symtab.c: the above.
2058 valops.c: the above. Handle pointer casts of object *'s.
2059 (search_struct_method): Add.
2060 (value_struct_elt): First arg is now a pointer to a value, and is
2063 valprint.c: the above.
2064 values.c (value_virtual_fn_field): Add type arg. Handle
2065 offsetting to the proper object when calling virtual fns.
2067 (baseclass_addr): Add valuep arg.
2069 * README: Document the current state of BFD config (missing).
2070 * TODO, ChangeLog, Makefile.dist: Roll version.
2071 * WHATS.NEW: Add summary of changes since 3.5.
2073 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
2075 * dbxread.c (read_struct_type): Clear bit vectors whenever
2077 symtab.c (B_CLRALL): define.
2079 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
2080 using == rather than =. Huh... This fixes the dreaded problem
2081 wherein builtin_type_int becomes TYPE_CODE_FLT.
2083 * core.c (info_files): Show the inferior pid.
2085 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
2086 already knows how to look in the source directory.
2088 * Remove psymtab hair from many places. Remove duplicated code
2089 for searching symbol tables. Hide psymtabs from most places.
2090 Make it fast to get from a psymtab to its symtab.
2092 blockframe.c (blockvector_for_pc): Remove psymtab hair.
2093 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2094 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
2095 dbxread.c: export psymtab_to_symtab, make it work if called N times.
2096 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
2097 new symtab completely. New psymtabs get symtab pointer
2098 initialized to zero. Remove MI warning printf.
2099 symtab.h: Comments. Add psymtab to symtab pointer.
2100 (PSYMTAB_TO_SYMTAB): New macro.
2101 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
2102 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
2104 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
2106 (print_frame_info): Avoid special-casing symbols that have not yet
2109 * source.c (open_source_file): Quick path if we have already
2110 located the source file by its full name.
2112 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
2113 find_pc_psymtab. When a name is found in the misc function
2114 vector, search the symbol table for its mangled name, not the
2115 name that the user typed.
2117 * bfd.h: Fix missing comment terminators, make #endifs match.
2119 * valarith.c (value_less): Handle unsigned int comparisons.
2120 Add FIXME about pointer compares, which assume host and target
2121 pointers are the same.
2123 * command.c (do_nothing_command): lint
2124 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
2125 fix comments on debug symbol format for visibility. Actually set
2126 visibility of symbols.
2127 main.c (echo_command): lint; use <readline/history.h>.
2128 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
2129 obstack.h (_obstack_blank): Rearrange pointer math to avoid
2130 pointing past end of allocated memory; saber complains.
2131 obstack.h: Declare the external functions that we use.
2132 valarith.h: use <string.h>
2133 solib.c (solib_add): lint.
2135 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
2137 * main.c (initialize_main): Default info_verbose to off, now that
2138 symbol reading is fast.
2139 (quit_command): Avoid clobbering exec_bfd while quitting.
2141 * Initial BFD (binary file diddling library) merger:
2142 coffread.c: Change AOUTHDR to struct exe_hdr.
2144 core.c: initialize initialized data at compile time.
2145 (core_file_command): Move from coredep.c, convert to bfd.
2146 (xfer_core_file): Convert to bfd.
2147 exec.c (exec_file_command): use bfd routines.
2149 mips-tdep.c: Remove exec_file_command and friends.
2152 * coredep.c: (fetch_core_registers) Convert core_file_command to
2153 fetch_core_registers.
2154 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
2156 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
2157 (my_bfd_read): More bogosity, which I don't think we call.
2158 (program_name): Remove this atrocity asap!
2160 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
2163 values.c: allocate_repeat_value was not clearing the
2164 optimized_out field.
2165 (value_static_field): minor stylistic fix (wrong macro was used).
2166 valops.c (value_struct_elt_for_address): didn't work for C++
2169 * signame.c (_initialize_signame): Initialize signal names once.
2171 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
2172 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
2173 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
2175 * remote-eb.c: Support user-settable baud rates on the serial port.
2177 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
2179 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
2181 * tconfig/sun3os4: Remove warning about native assembler,
2182 since it also occurs in the xconfig file.
2184 * findvar.c (registers): Allocate some slop after `registers'
2185 to prevent stray accesses from trashing the next variable.
2187 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
2188 on the sun-3, by changing the #ifdef from `sun3' (which is not
2189 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
2190 vars, which happened to follow `registers' in the executable.
2192 * readline/history.c (history_search): Heed gcc-2's advice
2193 and parenthesize && inside ||).
2195 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
2196 tm-29k.c: Insert FSF copyright headers.
2198 * remote-eb.c: Better comments.
2200 * Makefile.dist: Update to 3.91.6.
2201 * TODO: note PREPARE_TO_STORE problem.
2203 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
2205 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
2207 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
2209 * infrun.c (wait_for_inferior, at end): Don't set up
2210 prev_* if the inferior no longer exists.
2212 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
2213 CANNOT_EXECUTE_STACK.
2214 valops.c (call_function): Use it.
2216 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
2218 * inferior.h (PC_IN_CALL_DUMMY): New macro.
2219 infrun.c (wait_for_inferior, 2 places): Use it.
2221 * values.c (value_being_returned): Only use
2222 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
2224 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
2225 right thing for remote-eb.c.
2227 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
2228 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
2230 * blockframe.c: Put get_frame_saved_regs inside #if !defined
2231 (FRAME_FIND_SAVED_REGS).
2233 * findvar.c ({fetch,store}_registers): Check for
2234 REMOTE_{FETCH_STORE}_REGISTER macro.
2236 * findvar.c (get_saved_register): Add argument lval and
2237 change meaning of argument addr.
2238 findvar.c: Change calls to get_saved_register to reflect
2239 new calling convention.
2240 valops.c (value_assign): Use get_saved_register instead of
2241 find_saved_register.
2243 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2245 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
2246 an (uninitialized) pointer to one. Use "&" when passing it
2249 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
2251 * coffread.c (getfilename): Use DGUX x_offset and x_name if
2254 * coffread.c (symbol_file_command): Put semicolon after
2256 Put safe_to_init_tdesc_context in #if defined (TDESC).
2257 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
2258 coffread.c: #include <sys/stat.h>.
2259 (read_coff_symtab): Typo: in_source_files -> in_source_file.
2260 Add missing ')' in check for "lc%" and friends. Remove
2262 Declare read_one_sym() at top of file.
2263 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
2264 MC68WRMAGIC can have the same value without causing a duplicate
2267 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
2269 * Allow a Makefile to be built without building the
2270 tm and xm file links that screw up builds in subdirectories.
2271 This is done with `config.gdb none', then you can do things
2272 like `make gdb.tar.Z'.
2273 * tconfig/none: Config file for no target system
2274 * xconfig/none: Config file for no host system
2275 * config.gdb: If no TM or XM files are called out by the
2276 host or target file, don't make links for them.
2278 * cplus-dem.c: Add documentation.
2280 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
2281 simple error, so the user's gdb doesn't crash due to some object
2282 file problem (e.g. somebody is rebuilding the file out from under
2285 * printcmd.c (print_address_symbolic): demangle the symbol.
2287 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
2288 Motorola copyrights in it. Make "make gdb.tar.Z" work.
2289 (alldeps.mak): sort and uniq all results from this; duplicates
2290 hose gdb.tar.Z link building. Remove RCS files from
2291 tconfig and xconfig. Add config files for sun386. Add
2292 a few odd files to OTHERS and HFILES.
2294 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
2296 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
2297 Roll version number to 3.91.5. Make lint work in bindir.
2299 * README: Document cross-debugging and new file structure.
2301 * blockframe.c: Lint. Include "value.h" to declare read_register.
2302 (find_pc_partial_function): remove duplicate line.
2304 * command.h: Lint. Declare error_no_arg and dont_repeat.
2306 * tm-news.h: Remove inadvertently duplicated stuff.
2308 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
2309 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
2311 * config.gdb: Allow `config.gdb host target' form. Clean
2312 up previous change that printed bogus messages when you just said
2315 * core.c: #include "command.h" for lint.
2318 * main.c: Remove some casts of enums. Lint.
2325 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
2327 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
2328 read it from memory. This will allow us to save ptrace calls
2329 eventually. Changed caller single_step too.
2331 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
2332 that we aren't going to use, saving many ptrace calls, especially
2333 when watchpointing or single stepping. Use some #define's for
2335 (store_inferior_registers): Ditto.
2336 (core_file_command): Use some #define's for constants.
2338 * tm-sparc.h: Add #define's for some register numbers, so we
2339 can eliminate the use of random constants in sparc-xdep.c.
2341 * stack.c (frame_command, print_frame_info, up_command,
2342 down_command) Remove frame_changed, since it
2343 causes a bug and doesn't seem to do anything useful. In some
2344 places it was used as a flag, in others as a stack level (?).
2346 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
2347 default is to use the portable (vprintf) version rather than the
2349 * xm-news.h (MISSING_VPRINTF): Add.
2351 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
2353 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
2355 * Remove stuff that forces -Bstatic linking of gdb, and warnings
2356 about linking debugged programs -Bstatic in the sun?os4 config
2357 files in tconfig and xconfig subdirectories.
2359 * main.c (main): Remove unreached exit(0) now that we exit
2362 * Create TODO file for online bug list. There are too many
2363 "little" bugs to keep track of on paper.
2365 * Change Projects file to refer to bug-gdb@cygnus.com
2366 rather than kingdon@ai.
2368 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
2370 * Makefile.dist (VERSION): 3.91.4 now.
2372 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
2373 (condense_misc_bunches): Add sanity check that misc_count is
2374 the same as the number of symbols in the bunch.
2376 * coffread.c: rename init_misc_bunches. Pass an argument
2377 to condense_misc_bunches (a zero).
2379 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
2380 every time we are called; don't rely on our caller to do it.
2381 (add_file): Remove call to init_misc_bunches.
2383 * mipsread.c: Only warn, don't error, if unknown symbol types.
2384 This keeps an old gdb from falling on its face if it sees newly
2385 extended symbol info. Rename init_misc_bunches.
2387 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
2389 * Merge in changes from Per Bothner for DECstations and other
2390 MIPS stuff. The rest is Bothner speaking:
2392 The next message is a merger of Alessando Forin's mips port with
2393 mine. I've tried to use my good if biased judgment to get
2394 the best of both. It *does* need testing.
2396 Some of the changes are general, *not* mips-specific.
2399 Didn't believe in little-endian bit order.
2400 There are still inconsistencies about whether flags
2401 like BITS_BIG_ENDIAN are integer (#if ...) or
2402 boolean (#ifdef ...). I tried to paper over them.
2404 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
2405 Moved some misc_function code that was common to
2406 {dbx,coff,mips}read.c to symtab.c.
2407 In the process, I think I cleaned things up a bit.
2408 At the same time, moved obsavestring and obconcat to symtab.c.
2411 Removed obsolete condense_addl_misc_bunches (use
2412 condense_misc_bunches(1) instead).
2415 Needed to include <sys/dir>, at least on DECstations.
2417 valops.c, mips-tdep.c, tm-mips.h:
2418 Added PUSH_ARGUMENTS macro to support funny argument-pushing
2419 conventions (when STACK_ALIGN is insufficient).
2420 Needed on mips, where doubles need 8-byte alignment,
2421 but ints only need 4.
2424 Removed cruft that was not being used.
2425 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
2428 Print $ before register-names (I think that makes things a little
2430 Never print two instructions, even if one delays.
2431 Removed hex-disassemble set_cmd. (This is not mips-specific,
2432 so I think the argument is whether it is generally worthwhile or not.
2433 I'm inclined to think not, given how easy it is to
2434 convert between radixes in gdb.)
2437 This is basically Alessando's code.
2438 It doesn't use obstacks; I changed it to use obstacks
2439 in a few minor places where using malloc causes a
2440 memory leak. (Probably, more places could/should be changed.)
2441 I added record_misc_function where it was missing.
2442 In symbol_file_command and add_file_command, I tried
2443 to make the code consistent with more recent versions.
2444 Minor sylistic changes in parse_procedure.
2445 Make a .gdbinfo. psuedo-symbol point back to the real
2446 procedure symbol (using the isym field).
2449 This is basically from my port, but with a lot of details
2450 and a number of routines merged in from Alessando's version.
2451 I basically used my code "raw" backtrace (use heuristics
2452 from the actual code, rather than symbol table info) - though
2453 the idea is Alessandro's. I feel my code is a little cleaner
2454 here, particularly in being a little more flexible, such as being
2455 able to handle gcc-produced code (which it now can).
2456 It also doesn't do frame caching (which is not useful
2457 more recent gdb versions).
2458 I also used my code for push_/pop_dummy, more or less.
2459 I tried to incorporate AF's code for testing sigtramp
2460 while backtracing; I probably got it wrong.
2461 Added mips_print_register, which tries to scrunch as much
2462 information as possible on a screen...
2463 Removed the skip-prologue set_cmd. As with hex-disassemble (see
2464 under mips-pinsn.c), I don't see anything mips-specific here,
2465 and I don't see it being all that useful anyway.
2468 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
2469 Use more register names (rather than hard-cases numbers).
2471 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
2473 * Hack up 3.90.11 changes:
2475 * Makefile.dist (depend): parameterize $(GCC).
2476 Add solib.c and solib.o.
2477 (readline): Fix vpath for both absolute or relative SRCDIR.
2479 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
2480 Also, let the part I didn't understand at least compile so
2481 I can test the rest. FIXME.
2483 * dbxread.c: Fix thinko using strcmp.
2484 (init_psymbol_list): declare static.
2485 (partial_symbol_file_open): Comment cleanups better, avoid
2486 cleaning up the string table since the caller will do that.
2487 Move the stat for mod time into symbol_file_command, temporarily.
2488 (There should be a mod time for each symbol file, eventually,
2489 to control its rereading. FIXME.)
2491 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
2492 SunOS, which gives error for shared libs otherwise. (From
2493 Schaefer, probably FIXME needs work for portability.)
2495 * solib.c: Move #include "param.h" to work.
2496 Lowercase all the Uppercase Letters In the Messages.
2497 (find_solib): Clean up inferior_so_name for debug printouts.
2498 Allow no argument, to mean all shared libraries.
2500 * symmisc.c: include param.h to get CLEAR_SOLIB.
2502 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
2504 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
2505 to 3.90.11. ChangeLog entries below are from this.

2534 * Changes for Sun shared libraries:
2535 blockframe.c (find_pc_partial_function): If a non-text symbol
2536 is found, set *address = pc - FUNCTION_START_OFFSET.
2537 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
2538 Disable breakpoints instead of giving an error.
2539 source.c (select_source_symtab): Initialize cs_pst.

2544 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
2545 (record_misc_function): Give correct type for N_DATA symbols.
2546 (condense_misc_bunches): do "misc_function_count = j" regardless
2548 Take code which is shared between symbol_file_command and
2549 add_file_command and put it into partial_symbol_file_{open,read}.
2550 Split add_file_command into add_file_command and add_file.
2551 Make psymtab_to_symtab read in the string table if the file
2553 Two new parameters to read_dbx_symtab and start_psymtab.
2554 tm-sunos.h: New file.
2556 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
2558 * infcmd.c: Change cont_command to continue_command and "cont"

2563 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
2565 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
2567 * values.c (USE_STRUCT_CONVENTION): Check for structures of
2568 size 1,2,4,8 rather than size < 8.
2570 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
2571 as necessary, not just once.
2573 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
2575 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
2577 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
2579 * tm-news.h: Add CALL_DUMMY_*.
2581 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
2583 * config.gdb: In list_host, list_target, use ${i}, not $i.
2585 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
2587 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
2589 * sparc-opcode.h: Change all store floating-point state register
2590 instructions to have the right match & lose fields.
2592 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
2594 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
2596 config.gdb: If srcdir != ., create readline directory and
2597 copy a makefile into it.
2599 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
2600 consistency with POSIX.
2602 * breakpoint.c (bpstat_stop_status): Disable watchpoint
2603 when we exit its exp_valid_block.
2605 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
2607 * Makefile.dist: Bump version to 3.91.3.
2609 * Clean up handling of breakpoint commands (somewhat).
2610 Prompted by Tiemann bug report "cont 10" doesn't work any more.
2612 inferior.h: Add breakpoint_proceeded to inferior status struct
2613 and globals; save it and restore it.
2614 (clear_breakpoint_commands): Cleanup, remove old #define.
2616 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
2617 (save_inferior_status, restore_inferior_status): handle it also.
2618 (proceed): Remove earlier code that set breakpoint_proceeded.
2619 It is now set only in clear_proceed_status.
2620 (clear_proceed_status): Cleanup, use bpstat_clear rather
2621 than clear_breakpoint_commands. No callers need the stop_bpstat
2622 between clear_proceed_status and proceed.
2624 infcmd.c: Add breakpoint_proceeded definition and comment.
2625 (cont_command, jump_command, signal_command): Move call to
2626 clear_proceed_status right next to call to proceed.
2628 breakpoint.c (bpstat_do_actions): Avoid clobbering our
2629 caller's argument while running down the chain of breakpoints.
2630 Use new variable "breakpoint_proceeded" to determine when
2631 a command that it executes moves the inferior past the
2633 (bpstat_clear): Handle NULL argument.
2634 (bpstat_clear_actions): Avoid useless call to
2635 breakpoint_auto_delete.
2636 (delete_breakpoint): Clean up bpstat's that are pointing to
2637 the deleted breakpoint from the stop_bpstat chain.
2638 (breakpoint_auto_delete): Simplify.
2640 * Clean up handling of EOF, error on stdin, etc. This was
2641 prompted by a network problem that caused gdb to go into an
2642 infinite loop filling up its malloc'd memory.
2644 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
2645 not clear_breakpoints_commands, which is now gone.
2646 (main): If command_loop returns (e.g. from EOF on stdin), do
2647 a quit_command (looping back to command_loop if quit_command
2648 doesn't really quit).
2649 (command_loop): check result from command_line_input and
2650 exit if it returns NULL, rather than passing the NULL to
2652 (gdb_readline): Free malloc'd result space before returning
2655 * utils.c (query): Handle C-d to mean "yes", just as if the
2656 input was not a terminal. Also avoid infinite loop if EOF
2657 occurs in mid-input-line before newline. This allows
2658 query to be used at EOF on stdin with reasonable results.
2660 * infrun.c (proceed): Set breakpoint_proceeded.
2662 * values.c (value_as_long): Avoid infinite recursion for enums.
2663 (_initialize_values): Fix typo in help msg (kingdon).
2665 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
2666 RL_LIB for linking. This allows -lreadline for linking
2667 and nothing for dependencies, once readline is a real library.
2669 * config.gdb: Jim Kingdon: give useful error message if the
2670 host or target type is not recognized.
2672 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
2673 it just defines it. Dumb, but deal with it.
2675 * Jim Kingdon suggests:
2676 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
2678 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
2680 * Makefile.dist (VERSION): Bump version # to 3.91.2.
2682 * Clean up Bothner's changes.
2684 * blockframe.c (clear_pc_function_cache): New function.
2685 * blockframe.c: remake cache_pc_function_* static.
2686 * dbxread.c (symbol_file_command): remove references to
2687 cache_pc_function_* variables.
2688 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
2689 * printcmd.c: Avoid kludging a global variable (addressprint)
2690 to avoid printing the address of a string twice. Instead,
2691 pass the format letter 's' down low enough that it can be seen
2692 to avoid this problem.
2693 (print_formatted): Pass format arg to value_print.
2694 (restore_addressprint): Remove function.
2695 (do_examine): Avoid hacking addressprint, cleanups and such.
2696 (print_frame_args): Add a comment to a Bothner change.
2697 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
2698 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
2699 to wipe out the values cached in blockframe.c.
2700 * symtab.c (find_method): Add comment saying how big you must
2701 allocate to be "big enough". Per being terse again.
2702 * valprint.c (val_print): Handle format letter "s" to print
2703 strings without addresses. Add comment to vtbl printing code
2704 which casts with wild abandon. Rearrange reference-printing
2706 @0xaddr: value (print w/addressprint)
2707 value (print w/~addressprint)
2708 @0xaddr (parameter lists w/addressprint)
2709 or nothing (parameter lists w/o addressprint)
2711 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
2713 * Merge more changes from Per Bothner:
2715 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
2716 annoying) that I tried to improve it. Here are my suggestions.
2718 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
2721 Do automatic de-reference when taking the address of a reference.
2723 Don't deref_ref when printing parameter lists.
2725 More attempts at treating refernences properly.
2727 In val_print, if deref_ref==0, don't print dangling " = ".
2729 Add COERCE_REF macro, which de-references an REF.
2731 * Merge changes from Per Bothner:
2733 * Fixed (Sony news)-specific configuration problems.
2734 * Fixed other problems with using vanilla pcc and libc (enum problems;
2735 assumption that vsprintf exists).
2736 * Some major speed-ups (finc_pc_partial_function now caches a match;
2737 parsing avoids duplicate symbol_lookup calls).
2738 * Changed handling of baseclasses (no longer use baseclasses field
2739 of struct type, use the first n_baseclasses fields instead).
2740 * Various minor changes/fixes, most C++-related.
2743 Cache the most previous match from find_pc_partial_function.
2744 (Save both low and high ends of matching function's pc range.)
2745 This speeds up the loop of infrun.c:wait_for_inferior quite
2746 a bit, and makes step/next commands much zippier.
2748 Added an enum->int cast (otherwise, some compilers barf).
2750 No longer set baseclass offset to 0, since multiple
2751 inheritance now mostly works.
2752 Added a number of casts, to shut up compiler warnings
2753 (after stabs where made enums, not ints).
2754 When discarding a symbol table (in symbol_file_command),
2755 must clear the cache introduced in blockframe.c.
2756 Don't convert $vtbl_ptr_type to vtbl any more.
2757 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
2758 Mask off sign bit emitted by g++ for virtual table offset.
2759 Set voffset to -1 (not 1) for static member functions.
2761 Changed parsing/lexing of names to avoid doing symbol lookup twice
2762 (once when lexing to determine symbol class, once for real).
2763 Now only call symbol_lookup once. Fields of 'this' win especially big.
2765 Subpress printing addr twice in the case of 'x/s addr'.
2767 lookup_basetype_type is no longer used.
2768 Add find_methods as recursive helper function to decode_line_1.
2769 This allows multiple inheritance to work.
2770 Also, once one or more matches has been found, do not look in
2771 base-classes. (Baseclass methods would be overridden, anyway.)
2773 Removed baseclasses array in struct type.
2774 Instead of using baseclasses[i], use fields[i-1].
2775 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
2776 Changed sign convention of voffset (previous was inconsistent).
2778 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
2780 Used to assume existence of vsprintf. Re-written to not need it
2781 if HAVE_VPRINTF is undefined.
2783 typecmp was too pessimistic. Made it less so.
2785 Don't print space after address.
2786 If vtable points to a misc symbol (with 0 offset), print it,
2787 since that indicates the actual class of the object.
2788 Changed ype_print_derivation_info to use new inheritance
2789 scheme (without baseclasses vector).
2791 In value_primitive_field, fixed some bugs left over from previous set of fixes.
2792 Also, changes needed because TYPE_BASECLASSES were removed.
2794 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
2796 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
2799 If there is no path set, and the symbols don't indicate what directory
2800 a file was compiled in, look in the current directory. But either
2801 a path or a known compilation directory will prevent this.
2804 Three independent bug fixes:
2805 * Remove the #if 0 block that breaks some stuff.
2806 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
2807 adapt gdb to either SunOS 4.0.* or 4.1.
2808 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
2811 Instantiate the class T when looking for methods in it. (Tiemann@sun)
2814 (type_print) Demangle the name being printed.
2815 (type_print_base) Handle botched demangling without coredump (tiemann).
2818 (check_stub_method): Document routine.
2819 (tiemann) fix bug for no-arg functions
2820 Avoid clobbering beyond end of malloc'd storage.
2821 Terminate the argument list properly.
2823 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
2825 * Changes merged by John Gilmore:
2828 In breakpoint_1, use new print_address_symbolic instead
2829 of find_pc_partial_function. (This forces use of assembler-level
2830 addresses, and avoids misleading non-mangled source-level names.)
2832 Generalize ansi argument such that -1 means skip arglist totally.
2833 Removed global variable print_ansi_qualifiers (which made
2834 code non-reentrant), in favor of extra explicit arguments
2835 to internal routines.
2837 Add new helper function print_address_symbolic.
2838 Use find_pc_misc_function instead of find_pc_partial_function
2839 (since we want assembler-level symbols here).
2841 Print unknown function as just "f (...)", not "f (...) (...)".
2842 Use new fputs_demangled explicitly.
2844 Fixed a typing violation (problem: value.h cannot be imported
2845 without renaming many variable in this file).
2846 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
2847 decode_line_1: Moved forward some never-reached code.
2848 Made decode_line_2 skip function prologues correctly.
2850 fputs_filtered should not demangle by default.
2851 Add new fputs_demangled to demangle on demand..
2853 Change value_struct_elt to use value_primitive_field (using recursive
2854 utility function search_struct_field). This allows foo.bar to work
2855 for multiple inheritance (so far only for data fields).
2856 Change check_field in the same way (recursive helper function
2857 to support multiple inheritance).
2858 (Note: there are more of these problems that I haven't fixed.
2859 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
2860 value_of_this: 'this' symbol name is now just "this", note "$this".
2862 Don't print static members.
2863 Avoid printing "members of <type>" if there are none.
2864 Simplified type_print_derivation_info by merging duplicate code.
2865 Remove useless blank lines in type_print_base (ptype command).
2867 Added declaration of new routine value_primitive_field.
2869 Added value_primitive_field which is generalized version of
2870 value_field that can handle multiple inheritance (non-zero offsets etc).
2871 Re-implemented value_field to call value_primitive_field.
2873 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
2875 * infcmd.c -- insert else to avoid 'delete env' coredump when you
2876 delete the whole environment. Karl Berry reported the bug.
2877 * source.c - fix openp to avoid //'s in filenames, which
2878 trigger an Emacs bug causing it to not be able to find files
2879 when running gdb in a window.
2880 * dbxread.c - zap the #if 0 that botches the add-file code.
2881 It seems to work a lot better without all the code commented out.
2883 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
2885 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
2888 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
2890 * Makefile - added a ${CFLAGS} to a couple of entries,
2891 added remote-sa.sparc.c
2892 * added remote.sa-sparc.c, a modification of remote.c
2893 which conducts a dialog directly with the SparcStation prom.
2894 * breakpoint.c, infrun.c, sparcdep.c added
2895 remote_insert_breakpoint(), and remote_remove_breakpoint()
2896 to breakpoint.c instead of directly writing breakpoint instructions.
2897 * sparcdep.c on remote_debugging,there is no need
2898 to remove signle step breakpoint instructions.
2899 * main.c added "-epoch" flag and "int epoch_interface" to main.c
2901 * printcmd.c - epoch interface sends lisp expressions to open up
2902 epoch windows on inspection.
2903 * valprint.c - added arrayprint, and addressprint and made adding
2904 format controls easier
2905 * wait.h added a couple of undef's because we were getting
2906 complaints about WSTOPSIG and WTERMSIG begin redefined.
2909 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
2911 * symtab.c (decode_line_1): Add support for handling method stubs
2912 in the type information.
2914 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
2916 * values.c (baseclass_addr): Run loop from INDEX+1 to
2917 N_BASECLASSES; otherwise, we can still get into a loop.
2918 @@ This should be restructured to use a cleaner search strategy.
2920 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
2922 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
2923 abbreviation "Tt" for tags which have the same name as their
2926 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
2928 * symtab.c (list_symbols): add ability to set breakpoints on all
2929 the functions which match a particular regular expression.
2931 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
2933 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
2934 should print ANSI qualifiers (such as `const' and `volatile').
2935 All callers changed to call with ANSI == 1, except from
2936 `check_method_stub', which uses old-style syntax.
2938 * symseg.h (struct fn_field): Remove unneccessary `args' field.
2939 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
2941 * values.c (check_stub_method): New function.
2943 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
2945 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
2946 * valprint (type_print_base): Ditto.
2948 * symtab.c (gdb_mangle_typename): New function.
2950 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
2952 * breakpoint.c (catch_command): New function. Provides a
2953 mechanism to set breakpoints based on catch clauses.
2954 (disable_catch): Similar, but disables breakpoints on catch
2956 (delete_catch): Similar, but deleted breakpoints on catch clauses.
2958 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
2960 * blockframe.c (blockvector_for_pc): New function.
2961 * blockframe.c (block_for_pc): Changed to call
2962 `blockvector_for_pc' and get the block itself.
2964 * stack.c (catch_info): New function. Prints info about
2965 exceptions which can be caught in the current frame.
2966 * stack.c (print_frame_label_vars): New function. Similar to
2967 `print_frame_local_vars'.
2968 * stack.c (print_block_frame_labels): Prints out labels that are
2969 defined in this frame. These labels are exceptions that can be
2972 * dbxread.c: Updated to handle N_CATCH symtab types.
2974 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
2976 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
2977 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
2978 when printing the type.
2980 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
2982 * valprint.c (val_print): Use `baseclass_addr' to access the
2983 baseclasses pointed to via the derived class object at VALADDR.
2985 * values.c (baseclass_addr): New function. Casts derived pointers
2986 to baseclass pointers taking virtual baseclasses and multiple
2987 inheritance into account.
2989 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
2993 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
2995 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
2996 exp_valid_block field correctly.
2998 * infrun.c (wait_for_inferior): When checking "don't even think
2999 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
3000 also check step_resume_breakpoint.
3001 Insert breakpoints and continue (not step) if
3002 step_resume_break_address != NULL, even if another_trap.
3003 If trap_expected and we enter sigtramp, then set up a
3005 If trap_expected is set when we hit the step_resume_break,
3007 When calling resume and trap_expected says tell resume to step
3008 (2 places), also check step_resume_break_address.
3010 * infrun.c (wait_for_inferior): Don't set
3011 prev_{pc,sp,func_{start,name}} before calling wait ().
3012 Do set them after exiting loop.

3014 (start_inferior): Initialize them.
3016 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3018 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
3019 Restore old code which distinguishes between trap_expected and
3020 running_in_shell, just make the latter take any non-TRAP signal,
3023 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
3025 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
3026 xconfig/3b1 (CC,PINSN_CC): Define.
3028 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

3039 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
3040 xm-88k.h: Define USG_UTILS.
3042 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)

3045 (printf_command): Add from_tty parameter.
3047 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
3049 * value.h: Add optimized_out field and change lazy field to
3050 char. Add macro VALUE_OPTIMIZED_OUT.
3052 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
3053 instead of stuffing things in buffers (oappend, etc).
3055 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
3056 execute_command, exit both loops.
3058 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
3060 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3062 * Makefile.dist (RAPP_OBS, rapp),
3063 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
3065 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
3067 * valops.c (value_struct_elt), values.c (value_static_field):
3068 Change error messages to remove references to `info methods'.
3070 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3073 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
3074 infcmd.c [SHIFT_INST_REGS]: New code.
3075 findvar.c (read_relative_register_raw_bytes): Return a value.
3076 infcmd.c (do_registers_info): Check value from
3077 read_relative_register_raw_bytes.
3079 * command.c (delete_cmd): Free the struct cmd_list_element(s)
3082 Mon Apr 23 10:42:21 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3085 findvar.c (get_saved_register): New function.
3086 findvar.c: Rewrite code which called find_saved_register to
3087 call get_saved_register instead.
3089 Sun Apr 22 14:47:51 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3091 * valprint.c (val_print): Change error message printed when
3092 the type has TYPE_FLAG_STUB set.
