4 Fixed a variety of small typos that prevented info from formatting
5 cleanly; altered too-long heading for GPL Appendix, as discussed
6 w/RMS; Changed date on cover to July 91.
9 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
12 (1) Applied some fixes due to comments from Larry Breed (easier ones
14 (2) Eliminated use of @footnote---had my doubts about it anyways, and
15 it's broken in latest texinfo
16 (3) Introduced *some* use of [] for optional arguments, where
17 explanation is not simpler by listing cmd w arg and cmd w/out arg
18 separately. Still not using @deffn.
19 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
20 couple of headings are too long. Need patches to texinfo or revision
23 * Partial update to README (which still needs work for this
24 release!): (1) use of configure corrected for new script,
25 (2) "make gdb.dvi" and "make gdb.info" mentioned.
27 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
29 * symtab.c (lookup_symbol): Don't complain right off about
30 no debug symbols; use the misc function vector first.
31 (list_symbols): Use misc function vector to find symbols
32 that don't have debug info, and print them.
33 (find_pc_symtab): Temporarily avoid fatal() when psymtab
34 PC range doesn't match symtab PC range, as it does on the
35 MIPS because our symtab reading isn't perfect.
37 * dbxread.c (dbx_symfile_read): Make warning about
38 "no debug symbols" slightly nicer.
40 * source.c (select_source_symtab): If "main" symbol exists,
41 but decode_line_spec can't find line info, don't just return
42 a zero; try other source symtabs or give an error.
44 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
45 their low addresses first, then rip through fixing high addrs.
47 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
49 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
51 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
53 * Minor, mostly mechanical, cleanup of doc subdir for clean
54 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
55 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
57 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
59 Mostly MIPS and general symbol-reading fixups.
61 * doc/gdbint.texinfo: Add documentation on symbol-reading
64 * mipsread.c: Remove kludges around #include "ecoff.h".
65 Remove redefinitions of a_magic, etc, no longer used.
66 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
67 Fix global overview comments to match symfile.c protocol.
68 (mipscoff_new_init): Eliminate cur_hdr if we have one.
69 (mipscoff_symfile_read): Eliminate unused code. Avoid
70 sorting all the symtabs, when all we have read here is psymtabs.
71 The symtabs are sorted as they are created anyway. Tell
72 condense_misc_bunches whether we're mainline.
73 (psymtab_to_symtab_1): Pass filename when recursing, to make
74 stack trace more informative.
75 (parse_partial_symbols): Assume cur_hdr as argument.
76 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
77 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
78 the TYPE_NAME of char *, since that's done in symfile.c.
79 (free_numargs, parse_symbol, add_symbol, add_block,
80 shrink_linetable): Declare these fns void.
81 (upgrade_type): Convert tree of if's to switch. Clean up
82 bogus "off == 0" handling with a complaint. Avoid setting
83 field bitpos and bitsize of array with lower and upper bounds.
84 Check specified bitsize of elements against their actual type's
85 bitsize, and complain if different. Complain about unknown
87 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
88 (psymtab_to_symtab_1): Print names of subsidiary files that
89 are being read in. FIXME, we read far too many files. This code
90 is not the problem, the problem is in parse_fdr where the psymtabs
92 (cross_ref): Result should indicate that we used one aux entry
93 normally, or two if we encountered a "next" entry. This used
94 to leave the caller pointing at the wrong aux entry.
95 (add_symbol): If overflowed cur_block, reallocate it larger,
96 chase all pointers to it, and complain(), rather than clobber memory.
97 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
98 (new_field): Only allocate one field initially, not two.
99 Pull ++ out of macro argument. Simplify.
100 (_initialize_mipsread): Avoid initialization of importd
101 global_psymbols and static_psymbols.
103 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
104 to properly set pst->symtab; avoid searching for it.
105 (symfile_fns): Improve comments, add a FIXME.
106 * dbxread.c: Update comments to reflect symfile protocol.
107 (read_ofile_symtab, end_symtab): Return the symtab.
108 (psymtab_to_symtab_1): Set pst->symtab.
110 * coffread.c (coff_symfile_read): tell condense_misc_bunches
111 whether we're mainline.
113 * symfile.h (sym_fns): Remove unused sym_discard member.
114 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
116 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
117 the environment variable is not.
118 * infcmd.c (finish_command): Use filtered printfs.
119 * cplus-dem.c: Add struct tags to a few unnamed structs.
120 * valops.c (value_coerce_array): Improve comments.
121 * valprint.c (type_print_varspec_suffix): Print array size only
122 if greater than zero.
123 * m88k-tdep.c: Shift some lines left by one space, that had
124 apparently been trashed at some point.
125 * TODO: More things to do, a few got done.
127 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
129 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
130 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
132 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
133 * expread.y, findvar.c, symmisc.c: Ditto.
134 * printcmd.c (address_info): Update printed forms of LOC_
135 symbols. Elim LOC_EXTERNAL.
136 (print_frame_args): Keep track of param stack offsets before
137 re-looking up to find the local register param is kept in.
139 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
140 Further integration of mipsread into gdb. Eliminate unused
141 routines, duplicate declarations. Handle static symbols in
142 psymtabs as well as external symbols. When reading symtabs,
143 insert symbols into the correct block (global, static, or a local
145 (read_mips_symtab, parse_partial_symbols): Don't pass useless
147 (mipscoff_symfile_read): Don't call select_source_symtab.
148 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
149 rather than SYMBOL_VALUE.
150 (parse_external): Comment clobbering of top_stack.
151 (parse_partial_symbols): Update comments. Allocate and parse
152 static symbols as well as external symbols. FIXME, enum values
153 are not handled in this pass, but should be. Inline new_psymbol.
154 Use SYMBOL_VALUE_ADDRESS.
155 (psymtab_to_symtab_1): Read symbols into global static block
156 by default (until enter some function's local block context).
157 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
158 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
160 * source.c (select_source_symtab): Select a source symtab
161 from either the symtabs or, failing that, the psymtabs.
162 (list_command): Update error message.
163 (forward_search_command, reverse_search_command): Use getc, not
164 fgetc, for speed. FIXME, add comment about buffers that die if
165 overrun by long line.
167 * values.c (unpack_field_as_long, modify_field): Avoid shifting
168 by an entire word, which is not portable, if we have a 32-bit
169 field. (Code in dbxread.c already turns such bitfields, if
170 aligned, into ordinary ints, but fixing this will help for other
171 symbol formats and for future changes.)
172 * core.c (core_open): Handle ANSI const brain death.
173 * utils.c (vprintf): Fix varargs typo.
175 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
177 * findvar.c (find_var_value): Handle &function better.
178 * TODO: Document work needed on &fn and &array.
179 * printcmd.c (print_address_symbolic): New arg is the prefix
180 to print if a name is printed.
181 (print_address_demangle): Honor "set print address" now.
182 Use new arg above to improve spacing of output.
183 * valprint.c (val_print): When printing function pointers,
184 print symbolic form too.
185 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
187 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
189 * core.c (memory_error): Reword error msg to mislead less.
191 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
193 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
194 parse_partial_symbols): Use newer BFD internals (external_filehdr
195 and external_aouthdr), byte-swap the fields that we care about
196 before using them, and make the file header data local to
197 read_the_mips_symtab rather than global.
199 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
201 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
202 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
204 * main.c (command_line_input): Flush stdout and stderr
205 before every call to readline. This reportedly fixes a bug
206 that comes up in Sys V running emacs-gdb and/or xxgdb,
207 when stdin/out are pipes or sockets.
209 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
211 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
212 Avoid declaring Makefile dependencies, because GNU Make stupidly
213 tries to update it if we do.
215 * coffread.c: Revise for minor changes to bfd internal coff
218 * configure: If -template= is given a relative path, make it
219 absolute before recurring in subdirectories.
221 * configure, configure.in, Makefile.in: Install "configure" script
222 as replacement for config.gdb.
223 * config.gdb, Makefile.dist, Makefile.sdir: Remove
224 * README: Update for configure, mostly. FIXME.
226 * Add dec3100 as equivalent to littlemips. Indicate in all host &
227 target config files that they are for the host. When the lines
228 get copied into the Makefile, this makes it more obvious what's
231 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
233 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
234 tabs, which end up in the disassembler output inadvertently.
236 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
238 Make it compile cleanly in an ANSI GCC2 environment.
240 * blockframe.c: <stdio.h>
241 * cplus-dem.c: free takes a void *, ifdef __STDC__
242 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
244 * defs.h (alloca): Avoid doing anything if alloca already def'd.
245 * stddef.h, stdlib.h: Remove these files.
246 * symtab.c: Avoid declaring qsort, close.
247 * symfile.c: Avoid declaring close.
248 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
249 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
251 Assorted other changes.
252 * dbxread.c: include "libaout.h", not "liba.out.h".
253 * printcmd.c (print_frame_args): Set recurse properly for
254 indentation of struct and array parameters.
255 * valops.c (value_cast): Allow cast to void.
256 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
257 single_step() in a target-independent fashion.
258 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
259 set up to be ready to continue. This makes us target independent.
260 * infptrace.c (child_resume): Remove call to single_step; now
261 can single step a SPARC target of any kind.
263 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
265 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
266 docn into separate sections---basically chapters, plus two loose
267 pieces that can be configured to go in different places. This
268 allows GNU m4 to preprocess the manual without coredumping.
270 * Makefile.dist: tell TeX where to find texinfo.
272 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
274 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
275 the new target "rdl-apps.texinfo" which captures the Makefile
276 variable that records where to find the Readline libraries.
278 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
280 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
281 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
282 * defs.h (const, volatile): Only define if not already defined.
283 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
285 * README: Update for release 3.95.
286 * config.gdb: Don't create readline dir in subdir builds.
287 * main.c: Include with "..." form for non-system include files,
288 so "gcc -MM" for "make depend" works.
289 Include readline files with "...h" rather than <readline/...h>.
290 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
292 * coffread.c: Undo minor damage done by Rich Pixley. Use
293 different internal and external representations of COFF
294 data structures. Use new BFD routines for swapping them in and
296 * symfile.c (free_named_symtabs): Avoid freeing file names that
297 are null or empty. Old i960 tools seem to produce files that
298 claim to have empty names, causing each successive file read
299 to blow away the previous one.
300 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
301 Move deferred_stores to top of file, but don't separate its
302 #define's from its variable. Add commentary.
303 * Makefile.dist: Fix Rich damage; undo "configure" changes in
304 favor of keeping the (working) config.gdb. Move readline
307 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
309 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
311 * infptrace.c (fetch_registers): no result, since now void.
312 * tconfig/news: target depends on m68k-tdep too.
314 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
316 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
319 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
320 applied various small fixes due to or inspired by RMS comments
322 * doc/gdb.texinfo: finished using all RMS comments, save those for
323 appendices on readline and cmd history (which are in other source
326 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
328 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
329 chapter 9; (2) documented 'break' command's menu mode for
330 overloaded names, in response to hgs problem report C++ p-31
332 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
334 * doc/gdb.texinfo: (1) better introductory example; (2) more
335 consistent use of @code, @samp, @file, @kbd throughout; small
336 cleanups to first three nodes; (3) new "Contributors" node;
337 (4) Appendix, Renamed Commands; (5) divert specialized startup
338 instructions to "Targets" chapter for generic manuals, while
339 leaving them up front for manuals specific to specialized
340 environments; (6) apply fixes from RMS comments through chapter 4.
342 * pretex.m4: modify explanatory text slightly (and redefine
343 "regexp") to keep GNU m4 from complaining. (It still crashes
344 later, but one step at a time...)
346 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
348 * readline/readline.c (update_line): Avoid dereferencing a pointer
349 before comparing it to its bounds. Saber caught this.
350 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
351 and only set PC if tgetstr returned non-null. Saber caught this.
353 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
355 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
356 stuff for config manual) here where it counts; updated
357 to use new subdir structure (gdb/doc/).
359 * Makefile: generated from above via
363 * gdbint.texinfo: added instructions on generating gdb.info* files
364 locally for release. These are ordinary info
365 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
366 Makefile)---but due to use of texinfo 2, can't count on makeinfo
367 to generate these, so we distribute them already formatted.
369 * gdb.texinfo: included full Info node and menu crud (as generated
370 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
372 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
373 put in comments-for-future gdb.info target (one day makeinfo will
376 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
378 * gdb.texinfo: Updated to include new or old undocumented
379 commands, at least the following (perhaps some others I forgot to
380 record): info f, info float, info path, info program, info s, info
381 set, info source, info terminal, info types, info user, set/show
383 Also covered all recent GDB command renames for v4.
385 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
387 * mipsread.c: Rather than keeping count of how many symtabs
388 and psymtabs we have, for sorting purposes, count them when
389 we need to sort. This fixes bug in rereading of symbol tables.
391 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
393 * infcmd.c: renamed "info path" to "show paths"
394 * gdbrc.tex: documented above.
396 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
398 * remote.c: Fix comments.
399 * utils.c (error): Force out any pending wrap output.
401 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
403 * Makefile.dist: Roll VERSION to 3.95.
404 Fix up "saber_gdb" to work again.
405 * saber.suppress: Update.
407 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
408 symtab.h, target.c, target.h: Lint.
409 * core.c: setup and select frame after reading shared libs,
410 else reading shared libs will clobber them. Lint.
411 * utils.c (error): Force out any buffered wrap text.
413 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
415 * remote.c: Remove decls of memory_insert_breakpoint
416 and memory_remove_breakpoint, no longer used. (Suggestion of
419 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
420 to make it easier to interface to "configure"'d libraries.
422 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
424 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
425 aliases for set/show print.
427 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

453 {unpack_,value_as_}long (for now anyway).
455 * m88k-tdep.c (get_saved_register): Make get_reg a dc_word_t (*)().

458 * m88k-tdep.c (tdesc_read_function): Comment out call to ptrace.
460 * m88k-tdep.c (get_saved_register): Add lvalp parameter.
462 * gdbcore.h (write_memory): Don't prototype it.

467 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
469 * mtrace.c: Don't typedef things like size_t, just #define them.
471 * coffread.c [TDESC]: #if 0 out references to coffsyn.
473 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
474 tm-88k.h: Define EXTRA_SYMTAB_INFO.
476 * coffread.c [TDESC]: Include "tdesc.h" and make tdesc_handle
477 dc_dcontext_t not int.
479 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
481 * coffread.c [TDESC]: Move setting of debug_info from
482 coff_symfile_read to find_linenos and make it work with BFD.
484 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
486 * signame.c: Cast const char* to char* when assigning to sys_siglist.
488 * utils.c (strsave): Make arg const char* not char*.
490 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use
491 bpstat_explains_signal (stop_bpstat) not stop_breakpoint.
493 * tm-88k.h (START_INFERIOR_HOOK): Make tdesc_handle a dc_handle_t.
495 * tm-88k.h (EXTRACT_RETURN_VALUE): Use char * not void *.
497 * findvar.c (read_var_value, case LOC_CONST_BYTES): Put the address

992 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
993 defines for the blocks of a blockvector that contain global and
994 file-static symbols and the first of the smaller scope contours.
995 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
996 decode_line_1, make_symbol_completion_list): Use the above.
997 * coffread.c (end_symtab, patch_opaque_types): Ditto.
998 * dbxread.c (end_symtab): Ditto.
999 * expread.y (block): Ditto.
1000 * mipsread.c (throughout): Ditto.
1001 * symmisc.c (free_named_symtabs): Ditto.
1003 * symtab.c (list_symbols): Process the first symbol of the
1004 static psymbols list.
1005 (types_info): Restore this function from its untimely #if 0.
1006 It's not perfect, but it is better than nothing.
1007 (_initialize_symtab): Restore "info types".
1009 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1011 * m68k-stub.c: Remote stub for 680x0's, created from
1012 rem-m68k.shar (which is removed).
1013 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
1014 Remove RCS log stuff now that we use CVS and it blows our diffs.
1016 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1018 * symmisc.c (free_named_symtab): Make it work, in its current
1019 kludgy fashion. Change result to indicate if we blew away bkpts.
1020 * dbxread.c (end_symtab): Accumulate result from
1021 free_named_symtab and print warning if we blew user's state.
1022 * symfile.h: free_named_symtab now returns an int.
1024 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
1026 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
1027 is the first symbol read, even if not mainline.
1028 (dbx_psymtab_to_symtab): symfile might be zero, cope.
1029 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
1030 (set_section_command): New command ("section xxx yyy" -- should
1031 be renamed to "set section xxx yyy" FIXME) which sets the
1032 base address of a section of the exec file, overriding the
1033 virtual address that BFD reports.
1035 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1037 * exec.c: Add add_syms_addr_command to exec_ops, so you can
1038 load symbols at any address while examining an exec file.
1040 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1042 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
1043 for printing the float info is host-dependent, not
1044 target-dependent. FIXME.
1045 * i386-pinsn.c: Move #includes to top, remove useless ones.
1046 * i386-tdep.c: Don't bother including <.../reg.h> since we
1047 don't use it (and it doesn't exist on host systems).
1049 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
1050 Convert negative numbers properly.
1051 (ieee_test): Make numbers really random; fix format arg.
1053 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
1054 * core.c (core_detach): Unpush core_ops, which might not be on
1055 top. We used to just pop the top, which broke things. Don't
1056 need dont_repeat() any more.
1057 (core_file_command): Psst! Don't repeat it.
1058 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
1059 * expprint.c (print_subexp): Avoid switch fallthru on
1060 BINOP_ASSIGN_MODIFY, so we can print += and such.
1061 * frame.h: Fix typo.
1062 * inflow.c (kill_command): After killing inferior, print our
1063 current frame in the core file, if we have one.
1064 (generic_mourn_inferior): When inferior dies, either select
1065 the current frame (in the new target, e.g. core file), or
1066 set both the current and selected frames to NULL.
1068 Changes from Peter Schauer.
1070 * infptrace.c: Avoid <sys/ptrace.h> on USG.
1072 * Make all file names fit in 14 characters (sigh and damn!):
1073 mv hp300hpux-xdep.c hp300ux-xdep.c
1074 mv symmetry-xdep.c symm-xdep.c
1075 mv symmetry-tdep.c symm-tdep.c
1076 mv convex-opcode.h convx-opcode.h
1077 mv tm-vxworks960.h tm-vx960.h
1078 mv tm-vxworks68.h tm-vx68.h
1079 mv Makefile.srcdir Makefile.sdir
1080 mv gdb-int.texinfo gdbint.texinfo
1081 mv remote-sa.m68k.shar rem-m68k.shar
1082 mv remote-multi.shar rem-multi.shar
1083 * Makefile.dist, README, config.gdb, convex-pinsn.c,
1084 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
1085 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
1088 * command.c (user_info_1, user_info): New command for listing
1089 the user-defined commands.
1091 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1093 * dbxread.c (really_free_pendings): Clear file_symbols
1094 and global_symbols after freeing them; otherwise, running
1095 this function twice (if it appears twice on the cleanup
1096 chain), we try to free things twice.
1098 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
1099 based on text_addr (the address of text in core), not on addr (the
1100 offset between text in the .o file and in core). This change
1101 is from Peter Schauer.
1103 * main.c: Define ALL_CLEANUPS as a cast of zero.
1104 (return_to_top_level): Use it.
1105 (main): Do all cleanups after each command run as part
1106 of the gdb startup sequence. Also do all cleanups before
1107 entering the command loop, and every time we exit the command
1108 loop and reenter. Before, the cleanups from the startup sequence
1109 were being left undone until the first error!
1110 (command_loop): Rename do_nothing cleanup to command_loop_marker
1111 so we can see it easily when examining the cleanup chain.
1112 (init_signals): Add another do_nothing for signal handling.
1113 (quit_command): Only try to kill target if it has execution.
1114 Problems in the target stack got us into a state where
1115 inferior_pid was nonzero but none of the targets had execution.
1116 In this state you couldn't exit gdb.
1118 * dbxread.c: Two changes from Peter Schauer.
1119 (echo_command): Fflush output after an echo command.
1120 (show_history): Pass all args to cmd_show_list.
1122 * utils.c (init_malloc): Call mtrace to turn on tracing
1123 if the environment variable MALLOC_TRACE is set to a file name.
1124 * mtrace.c: Add source file which provides a log of every malloc,
1125 free, and realloc to a trace file.
1126 * mtrace.awk: Add source file which analyzes the trace file.
1127 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
1128 (VERSION): Roll to 3.94.3.
1130 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
1131 (check_duplicates): Don't bother with watchpoints.
1132 (set_raw_breakpoint): Comment about danger of this routine.
1133 (watch_command): Parse and eval all args before calling
1136 * solib.c (find_solib): Avoid error in referencing memory to
1137 see if any more shared libraries have been added. This is
1138 particularly useful if the target has terminated. Bug reported
1141 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
1142 in bringing up 3.94.2 on the Sun-3.
1144 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
1145 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
1146 expression (in scope) before reenabling watchpoint.
1147 * signame.c (init_sigs): Add missing declaration of i, fix
1148 sys_siglist declaration.
1149 * source.c (list_command): Fixed range computation to use
1151 * stack.c (backtrace_command): Do not allow command if target has
1152 no stack, print informative error message.
1153 * target.c (target_command): Do not write into command line
1154 because this fails if the target command is used in a user defined
1155 command. [This change was enhanced by gnu to support any-
1156 unique-prefix matching on target names.]
1157 * valops.c (value_struct_elt): Avoid infinite loop on an
1158 erroneous attempt to print the member of function (try p main.p).
1160 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1162 * expread.y (name_no_typename): Avoid reduce/reduce errors
1163 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
1164 Since the GDB parser really doesn't use name_no_typename in a
1165 name-only context, the parser can't tell the diff between
1166 names and numbers here. Avoid allowing a name_no_typename
1167 to be a NAME_OR_*INT to resolve the conflict.
1169 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1171 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
1173 * valprint.c (val_print_fields): bitfield printing didn't handle
1174 byte order. Indirect through a few more fns to cope.
1176 * values.c (modify_field): also cope with byte order.
1178 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1180 Cleanup for release 3.94.2:
1182 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
1183 include files. Roll version to 3.94.2.
1185 * coffread.c (init_stringtab): Read length into unsigned char
1186 array before swapping; don't assume 32-bit longs.
1188 * target.c (target_info): Don't bother with get_sym_file, just use
1189 the symfile global variable.
1190 * symtab.h, symfile.c (get_sym_file): Delete it.
1192 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
1193 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
1194 (read_type): Replace one more error() with complain().
1196 * mipsread.c (parse_partial_symbols): Replace printf with complain.
1198 * i960-tdep.c: Fix copyright attribution.
1200 * config.gdb: Quote all backquotes in doublequotes. You can
1201 quote me on that. BSD 4.4 shell found this one.
1203 * infptrace.c (throughout): The third argument to ptrace is an
1206 * infrun.c (wait_for_inferior): When program has terminated, we
1207 have to call target_terminal_ours before we pop that target off
1208 the stack (e.g. before a call to target_kill or
1209 target_mourn_inferior). This fixes problem where a program
1210 terminates, then GDB stops for (tty output) and you have to type
1211 "fg" to the shell to resume it. FIXME: This code for what to
1212 do after termination really should be in normal_stop instead.
1214 * gdbcore.h (read_memory_check): Change declaration; it changed
1217 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
1218 4.4 prereleases, this avoids a bug in their sgtty compatability
1220 * remote.c: Use terminal.h rather than hand-rolling the same.
1222 * signame.c, signame.h (psignal): Arg is unsigned, not int.
1223 * utils.c (strsave, strstr): Fix arg types.
1224 * valprint.c (val_print): lint
1226 MIPS symbol table support from Per Bothner:
1228 * symfile.c (symtab_fns): Remove initializer table that needs to
1229 be hacked for each new symbol file format supported.
1230 (add_symtab_fns): New function, chains symbol table
1231 handlers into the global list.
1232 (symfile_init): Search this list.
1233 * symfile.h: Add next pointer, declare add_symtab_fns.
1234 * coffread.c (_initialize_coffread): Call add_symtab_fns.
1235 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
1237 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
1238 symbol *). Thus, we no longer need the hack to trash
1239 pst->filename. Good, since that hack confused code in symfile.c!
1241 (reorder_symtabs, destroy_all_symtabs): Removed static
1242 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
1243 Instead, the latter now uses a temporary array (stack-allocated
1244 from an obstack, and then freed).
1246 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
1247 haven't been set in the outermost stBlock of a procedure. This was
1248 a problem with f77 binaries on Ultrix 4.?.
1250 (new_symtab, new_symbol, new_type): Continue changing code to use
1251 obstacks more and otherwise conform to dbxread internal style.
1252 Made the free_code of symtabs be free_linetable (as in dbxread)
1253 instead of free_contents. This implies memory leaks when reading
1254 a new symbol table, until the conversion is finished. Did change
1255 (struct symbol) and (struct type) to be allocated on the
1256 symbol_obstack. Blocks and blockvectors are among the things
1259 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
1260 tested much, but it solved one problem (reported by Meissner), and
1261 cleans up some other things. The problem happened when an
1262 included file contains actual code (functions) and not just
1263 definitions. The mips coff is a little inconvenient there, since
1264 it may cause a procedure to be mapped to the wrong psymtab.
1266 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
1267 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
1268 this will need work for the new core paradigm.
1270 Opcode patches from the net:
1272 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
1273 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
1274 missing altogether - they are added here. From Bruce Bauman.
1275 * mips-opcode.h: The low mask for C0 instructions was too small.
1276 From Garrett Lau. I modified the fix to check the entire 32-bit
1279 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
1282 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1284 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
1286 * dbxread.c (read_type): Pointer subtraction (value_sub in
1287 valarith.c) sometimes failed because the types of the
1288 pointers being subtracted were not identical.
1289 These differed because dbxread.c was allocating pointer types
1290 using dbx_alloc_type+smash_to_pointer_type instead of
1291 lookup_pointer_type. I failed to find a justification for the
1292 former, so I changed it to use the latter. Similarly, I
1293 replaced smash_to_function_type by lookup_function_type,
1294 and smash_to_reference_type by lookup_reference_type.
1296 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
1297 _initialize_mipsread): corresponding changes.
1299 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
1301 * source.c (mod_path): Do tilde_expand on each component of the path,
1302 rather than on the (list of) paths as a whole.
1303 (print_source_lines): Set first_line_listed in addition to
1304 current_source_symtab and current_source_line. If the source was
1305 not findable, after a "dir" command to fix the problem,
1306 a "list" would get the wrong lines.
1308 While I was there... (gnu):
1310 * dbxread.c (read_type): Change error to complaint.
1312 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1314 First attempt at detailed understanding of symbol table memory alloc.
1316 * dbxread.c (dbx_symfile_read): Free our string table if we
1317 aren't the mainline. Free the "info" struct since we're done with
1319 (init_psymbol_list): Free any previously allocated psymbol lists.
1320 (): FIXME: Should realloc-down the psymbol lists when done reading
1321 the main symbol file?
1323 * symmisc.c (free_symtab): Free fullname field too.
1325 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
1326 (REGISTER_ADDR): Make result type unsigned int.
1328 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
1329 define REGEX must also define REGEX1 (its dependency).
1331 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1333 * tconfig/i960: No longer works, points you at vxworks960 or
1336 * xgdb.c, XGDB-README: Remove file. Users can get the much
1338 * Makefile.dist: Remove all trace of xgdb.
1340 * breakpoint.c (breakpoint_1): Pass demangle arg to
1341 print_address_symbolic.
1342 (clear_breakpoints): Remove unused function.
1343 (breakpoint_re_set_one): Guts of breakpoint_re_set.
1344 (breakpoint_re_set): Use catch_errors to do them all anyway.
1346 * gdb-int.texinfo (Host versus Target): Add section on what is
1347 a "host" feature versus what is a "target" feature.
1349 * infcmd.c (path_command, path_info): Handle the PATH variable
1350 (object search path) as conveniently as the source search path.
1351 * environ.c (set_in_environ): Set some vars in GDB's environment,
1352 in addition to the child's. PATH, G960BASE, G960BIN for starters.
1353 * source.c (mod_path): New function, from guts of
1354 directory_command, modifies a path. Used by path_command.
1355 (directory_command): Call it.
1356 * defs.h (strsave): Declare.
1358 * utils.c (sevenbit_strings): Add new printing option.
1359 (printchar): Use it.
1360 (strsave): Provide this handy helper routine.
1361 (set_width_command): Rename set_screen_width_command.
1362 (_initialize_utils): "set screen-width" => "set width";
1363 "set screen-height" => "set height"; add sevenbit-strings.
1365 * infcmd.c (do_registers_info): Print floating point registers
1366 in raw hex as well as float format, regardless of whether it is
1367 a "virtual" convertible register.
1368 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
1369 regs as a double, just in case it's being used that way.
1370 * values.c (unpack_long): Comment on array/function coercion.
1371 (unpack_double): Argument is in target byte order now. For
1372 integer arguments, just call unpack_long and float the result.
1373 * m68k-tdep.c: include defs.h for "const" handling.
1374 * remote-nindy.c: Use ieee-float stuff.
1375 (nindy_fetch_registers): Unpack double regs to host double, then
1377 (nindy_store_registers): Pack extendeds to host double, flip
1378 around by misusing unpack_double, send as target double.
1380 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
1381 zero, as when stopped at the first instruction of a process.
1383 * blockframe.c: Fix filename in comment (param.h => tm.h).
1384 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
1385 * tm-68k.h: Fix typos.
1387 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
1389 Changes from a bringup on the DEC Vax under Ultrix 4.0.
1391 * coredep.c (fetch_core_registers): Pass end-address of register
1392 section to register_addr as expected. Don't call supply_register
1393 if we'd just pass it garbage.
1395 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
1397 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
1399 * target.c (push_target, target_info): Cast enums to int for < or
1402 * stack.c (print_frame_info): Identify source file & line
1403 even if we can't print it.
1405 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
1407 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
1409 Clean up IEEE floating point support.
1411 * ieee-float.h: New file.
1412 * ieee-float.c: Write real routines to convert between host
1413 doubles and various target IEEE extendeds.
1414 * m68k-xdep.c: Eliminate assembler code for extended floats.
1415 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
1416 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
1417 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
1418 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
1419 double_to_ieee_extended.
1420 * i960-tdep.c: Define ext_format_i960.
1421 * m68k-tdep.c: Define ext_format_68881.
1422 * sparc-tdep.c: Define ext_format_sparc, though unused.
1423 * Makefile.dist (HFILES): Add ieee-float.h.
1424 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
1427 Obsolete the "coffstrip" program in favor of using BFD's strip.
1429 * nindy-share/coffstrip.c: Remove file.
1430 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
1431 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
1432 * tconfig/nindy960: Remove reference to coffstrip.o.
1434 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
1436 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
1438 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
1439 * dbxread.c: Remove static symfile_bfd.
1440 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
1442 * inftarg.c (child_detach): Pop the child_ops vector if the
1443 detach is successful.
1444 * remote-nindy.c (nindy_create_inferior): Don't push a new
1445 nindy_ops since nindy uses the same one for execution and memory
1447 * core.c (core_ops): Use child_attach and child_create_inferior
1448 rather than default attach and create_inferior functions.
1450 Handle floating point registers in core files.
1452 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
1453 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
1454 This version untested since BFD doesn't yet support sun3 core
1456 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
1457 conventions. Fix comments and style. This version has not
1458 been compiled yet, since we have no HP inhouse.
1459 * core.c (get_core_registers): Look for two sections, ".reg"
1460 and ".reg2", and pass both to fetch_core_registers sequentially.
1462 Revise directory path yet again.
1464 * source.c (forget_cached_source_info): Not static any more.
1465 (init_source_path): New default source path is "$cdir:$cwd".
1466 (dir_command): Handle variable arguments ($cdir, $cwd).
1467 (source_info): Print "Compilation directory" rather than
1468 "Originally compiled in" to remind people of $cdir.
1469 (openp): If the path contains $cwd, use current directory.
1470 (open_source_file): If compilation directory is known, replace
1471 first $cdir in path with the compilation directory.
1472 (print_source_lines): Even if we can't print the lines, set the
1473 current symtab and line for future commands like "info source" or
1474 "breakpoint". Also, error message now contains the file name,
1475 line number, and file access error message.
1476 (_initialize_source): Fix help text to describe changes.
1477 * main.c (cd_command): Forget cached source info when we chdir.
1478 * utils.c (strstr): Add simple implementation.
1480 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
1482 * coffread.c (read_one_sym, init_linetable, init_stringtab):
1483 Byte-swap COFF symbol tables if necessary when reading them in.
1484 Use complain() to replace error message in one spot. Needs
1485 corresponding change in bfd/coff-code.h to make some symbol
1486 swapping routines non-static.
1488 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1490 Merge changes from Eirik Fuller, for UTek.
1492 * defs.h (errno): Add declaration.
1493 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
1494 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
1495 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
1496 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
1497 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
1498 declarations of errno.
1500 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
1502 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
1503 <rpc/rpc.h> and <rpc/types.h>.
1505 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
1507 * i960-tdep.c (examine_prologue): Add new argument limit,
1508 which stops the scan at the end of the prologue, or at the PC.
1509 This fixes a problem where it walks down into the code for the
1510 user's statements if that code looks like function prologues.
1511 Mark Fox and I have been bouncing this code back and forth, making
1512 small changes to it. Callers changed to match.
1514 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
1516 Cleanup for gdb-3.94 release final:
1518 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
1519 the .c files from vx-share and nindy-share, from the various
1520 macros, since they are not found via ALLDEPFILES.
1521 (SFILES): Add tm-i960.h.
1522 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
1523 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
1525 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
1526 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
1528 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
1530 * am29k-tdep.c: Add contribution line.
1531 (examine_prologue): Cache information about function prologues in
1532 the misc-function-vector to avoid lots of references over the
1533 serial line while examining instructions.
1535 * core.c (core_close): New function made from cleanup_core.
1537 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1538 remote-vx.c, remote.c, target.c, target.h,
1539 Update target_ops vector to add attach, close, and load entries.
1540 Use add_syms_addr_command, not add_file_addr_command, for
1541 add_file. Break out close routine from existing code.
1543 * dbxread.c (really_free_pendings): Don't free pending_blocks;
1544 they are in an obstack.
1545 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
1547 (define_symbol): Add symbol type parameter; change callers;
1548 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
1549 it to influence the symbol class on the i960.
1550 (define_symbol): Swap LOC_CONST's into target byte order.
1552 * exec.c (exec_close): New function.
1553 (exec_file_command): Call it.
1555 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
1556 Fix byte order of frame pointer.
1557 (read_var_value): Result of 0 if var's value can't be found,
1558 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
1559 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
1560 (locate_var_value): Use read_var_value and use its lazy address
1561 as the location of the var's value. Lint.
1563 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
1566 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
1567 obsolete Intel versions in favor of vxgdb versions.
1568 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
1569 code dealing with byte order of values, which Intel did in host byte
1570 order rather than gdb-4's target byte order.
1571 (i960_frame_chain_valid): Move to nindy-tdep.c.
1572 (examine_prologue, skip_prologue, frame_find_saved_regs,
1573 frame_args_address, leafproc_return, saved_pc_after_call,
1574 pop_frame): Add vxgdb versions from Mark Fox.
1575 (examine_prologue, frame_struct_result_address): Add code
1576 to deal with the saved value of G13 (struct return address
1578 (frame_args_address): Modify Mark's version to prefer the
1579 saved value over the current value in the topmost frame.
1580 Cache result in the frame info to avoid performance hair in
1582 (print_fault): Add gdb960 code for printing faults.
1583 (_initialize_i960): Actually call check_host.
1585 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
1586 add stub routines. FIXME, these currently just return zero!
1588 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
1589 (attach_command): Call target_attach, not target_open, now.
1591 * infrun.c (normal_stop): Make global, not static, for vx_attach.
1592 (child_attach): Rename from child_open.
1593 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
1594 don't confuse it with a zero step_resume_break_address.
1596 * inftarg.c (child_detach): Eliminate inferior_pid test.
1597 (child_files_info): Clean up message a bit.
1598 (child_ops): Use child_attach, not child_open, to attach.
1600 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
1601 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
1602 findvar.c to here, since it depends on the contents of the
1603 shadow_contents of breakpoints, but keep if #if 0 since it is
1606 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
1609 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
1610 (ptype_command, display_command): Eliminate have_inferior_p and
1611 have_core_file_p in favor of target_has_stack or
1612 target_has_execution.
1613 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
1614 code for actually finding the values of arguments, though we still
1615 keep track of the maximum stack offset for use in printing unnamed
1616 arguments. Handle missing FRAME_ARGS_ADDRESS.
1618 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
1619 (struct nindy_regs): Define registers passed to/from nindy.
1620 (nindy_fetch_registers, nindy_store-registers): Translate between
1621 nindy and GDB formats for the registers.
1622 (dcache_init): Statically allocate the cache, since it was being
1623 allocated by a malloc that was never freed anyway.
1624 (nindy_create_inferior): Error, not core dump, if no exec file.
1625 (nindy_before_main_loop): Use target_load, not target_add_file.
1627 * remote-vx.c (net_load): Specify large timeout for load
1628 requests. Allow user to break out with INTERRUPT.
1629 (net_break): Remove useless code, clean up. Change callers.
1630 (parse-args, skip_white_space, find_white_space): Clean up arg
1631 parsing to cope with quoted strings.
1632 (net_wait, net_quit): Never call error, just return status.
1633 (vx_read_register, vx_write_register): Cleanup status checking.
1634 #ifdef the code based on which CPU we are using (960 or 68k),
1635 FIXME, this should be completely general but it isn't yet.
1636 (vx_xfer_memory, vx_resume): Cleanup status checking.
1637 (vx_run_files_info): Improve message.
1638 (vx_load_command): Renamed from vx_add_file_command. Allow load
1640 (net_ptrace): Remove unused routine.
1641 (vx_wait): Adopt code from vxgdb960 to cope with broken
1642 connections to target machine and prompt to disconnect. Remove
1643 debug printouts. Map some EVENT_'s to SIGnals.
1644 (add_symbol_stub, vx_open): Print names of object files we found,
1645 and "ok" if we read their symbols OK. Clarify output in general.
1646 (vx_attach, vx_detach, vx_kill): Add these commands.
1647 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
1648 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
1649 "info files" output, and create_inferior, since we already have
1652 * stack.c (frame_info): Replace Frame_unknown with 0.
1653 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
1654 (return_command): Pop until the PC matches as well as the FP,
1655 so it works even if the FP is shared with another function,
1656 as in "frameless" or "leaf" procedures.
1658 * symfile.c (load_command): renamed from add_file_target_command.
1659 (add_syms_addr_command): renamed from add_file_addr_command.
1660 (add_syms_command): Stub to call target_add_syms.
1661 (_initialize_symfile): Change command names and descriptions,
1662 add-file => add-syms, and load from alias to its own command.
1664 * target.c (kill_or_be_killed, maybe_kill_then_attach,
1665 maybe_kill_then_create_inferior): Default for attempts to start
1666 a process, if one is already running, is to ask about killing
1667 it and retry if yes.
1668 (upstack_create_inferior): #if-0 it, strata obsolete it.
1669 (push_target, unpush_target, pop_target): to_close() a target
1670 before unstacking it.
1671 (target_info): Renamed from target_files_info.
1672 (_initialize_targets): Rename "i files" as "i target", accessible
1675 * target.h: Improve comments about the target_ vectored routines.
1677 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
1678 Convert commenting style to standard GNU style.
1679 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
1680 (SKIP_PROLOGUE): No longer a no-op.
1681 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
1682 (*_REGNUM): Sort register numbers.
1683 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
1684 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
1685 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
1686 are now 10 byte extendeds, not 8 byte doubles.
1687 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
1688 for nindy versus vxworks targets. FIXME, this should possibly go
1689 in the target vector.
1690 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
1691 frame_saved_regs and arg pointer with each frame.
1692 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
1693 (FRAME_ARGS_ADDRESS): Use cached result.
1694 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
1695 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
1696 (PRINT_RAMDON_SIGNAL): Call print_fault.
1697 (POP_FRAME): Now works.
1699 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
1700 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
1701 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
1702 (ADDITIONAL_OPTION_HANDLER): use target_load, not
1705 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
1706 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
1708 * valarith.c (value_subscripted_rvalue): Avoid handling
1709 floats and doubles specially; it gave alignment errors. Lint.
1711 * valops.c (value_of_variable, value_of_this): Error if unknown
1714 * valprint.c (print_floating): Bcopy rather than pointer-deref,
1715 to avoid alignment problems.
1716 (value_print): Handle unknown value address.
1717 (cplus_val_print): Two args are ignored; remove them. Change caller.
1718 (val_print): Use unpack_long rather than pointer-deref.
1721 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
1722 to avoid alignment problems.
1723 (value_being_returned): Error if return value unknown.
1724 (set_return_value): Add bogosity warning, FIXME. *
1726 * TODO: A woman's work is never done.
1728 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
1729 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
1730 Add ieee-float.o to OBS.
1731 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
1732 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
1733 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
1735 Changes to generalize the VxWorks RPC protocol slightly, to handle
1736 i960 as well as 68000.
1738 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
1739 * vx-share/reg.h: Produce i960 regs #ifdef I80960
1740 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
1741 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
1742 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
1743 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
1744 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
1745 so they will move in target byte order rather than network
1746 byte order (happens to be the same).
1748 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
1750 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
1752 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1755 Add contribution lines to various files, showing where they
1758 * breakpoint.c (break_insn, check_break_insn_size,
1759 read_memory_nobpt): Remove to mem-break.c.
1761 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
1764 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
1765 entry has bad register number. This change is not
1766 tested in this release, FIXME.
1768 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
1771 * value.h: Force value's contents field to be aligned to hold
1772 at least a double or a long long (if supported). This avoids
1773 doing bcopy's in and out of the contents field.
1775 (step_1): Avoid coredump under obscure circumstances when we
1778 * symtab.h (misc_info): Add field to misc function vector for
1779 any kind of cached information the target code desires. AMD
1780 29000 uses this to avoid repeating examine_function_prologue's.
1782 * coffread.c: Lint. Remove static symfile, read_section_header.
1783 core.c (have_core_file_p): Lint: remove.
1784 expprint.c (print_subexp): Lint.
1785 infptrace.c, valops.c, valprint.c: lint.
1787 Roll in changes from vxgdb-5.0.1:
1789 * symtab.h: Comment byte order of each address class. Add
1790 LOC_LOCAL_ARG for frame-relative args (960).
1791 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
1792 symtab.c, symmisc.c: ditto.
1794 * infrun.c (init_wait_for_inferior): Clear stop_signal.
1796 * remote.c (remote_resume): Error if resume with a signal.
1798 * symfile.c (prim_record_misc_function): Clear misc_info.
1799 (fill_in_vptr_fieldno): Check stub type of arg.
1801 * valops.c (value_cast): Avoid looking up names of types whose
1802 name we don't know, to prevent coredump. Sun CC produces typedef
1803 rtx and the name of *rtx is zero...
1805 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1807 Roll in changes from final AMD 29000 port (Tiemann).
1809 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
1810 for ../include/a.out.encap.h. This might not work now that BFD
1811 is separately compiled. Instead, BFD support for encap will have
1812 to translate machine type 29k into the right COFF_MAGIC.
1814 * infcmd.c: Remove references to inferior_pid that aren't used
1815 in actual ptrace calls; use target_has_execution, etc.
1816 (have_inferior_p): Remove function.
1817 (program_info): Print target info rather than "process number";
1818 avoid gratuitous messages unless from_tty.
1819 (run_stack_dummy, finish_command): Set proceed_to_finish.
1820 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
1821 main.c: Lint. Lose have_inferior_p().
1822 inferior.h (have_inferior_p): Remove, lint.
1823 (proceed_to_finish): Add flag to ask that all regs be saved
1824 by normal_stop, for the few commands that need it, speeding up
1825 serial I/O. Add comments to stop_registers.
1827 * remote-eb.c: Remove newline from breakpoint message we grep
1828 for. Never time out when running the user program.
1832 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
1834 Roll in changes from vxgdb-5.0.1:
1836 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
1837 symbol in its raw form, we are processing an unlinked ".o" file.
1838 See if the target environment has assigned it an address, using
1839 target_lookup_symbol (VxWorks does), and enter it into the symtab
1842 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
1843 68k versions for a simpler version that assumes zero FP at bottom.
1844 Fixes bug of truncated stack reports.
1846 * target.h (target_lookup_symbol): Define this routine's args
1847 and result, finally.
1849 * target.c (nosymbol): Default routine for target_lookup_symbol.
1850 (target_default): Default lookup_symbol and call_function too.
1851 (files_info): Only print has_all_memory warning if a non-dummy
1854 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
1855 vx_convert_from_virtual): If target does not have floating point,
1856 zero register "values", and avoid doing cross-net conversions.
1857 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
1858 (vx_open): Rearrange code that attaches to target and reads
1859 symbols for all loaded modules, to work if some of the modules
1860 are not accessible. Add symbol_stub() and add_symbol_stub()
1861 as callbacks from catch_errors(). Allow connect attempt to be
1862 interrupted painlessly with ^C (FIXME, there are still some bugs
1863 if the interrupt happens during symbol reading.). Print
1864 final message with puts_filtered, since symbol messages are
1869 * main.c (catch_errors): Only print errstring if non-null.
1870 (command_loop): Avoid an ioctl per command to test ISATTY.
1872 * remote-vx.c (net_load): make static; avoid sophomoric msg.
1873 (vx_xfer_memory): Return correct result!
1874 (vx_files_info): Indicate whether target has float or not.
1875 (vx_lookup_symbol): Complain, not error, if target gone.
1876 (vx_open): Print "Connected" msg before disabling immediate-quit.
1877 [FIXME: lookup_symbol and vx_open changes need testing.]
1879 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
1880 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
1881 contributor lines and update copyrights to 1991.
1883 Changes from an attempted H-PUX host port:
1885 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
1886 defines PT_ATTACH and PT_DETACH but not PT_KILL.
1887 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
1888 * remote-vx.c: include <sys/time.h> for HPUX.
1889 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
1890 "core_file_command" routine to BFD regime. May not work yet.
1892 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
1894 * xgdb.c: Replace X10 version with some VJ version.
1895 (FIXME: Its copyright assignment is not on record.)
1896 * xgdb.c: Update include files to X11R4 (Xaw crud).
1897 (xgdb_display_source, create_text_widget): fix call to
1898 get_filename_and_charpos. Rewack source window stuff for X11R4
1899 (gleaned from include files, and "nm's" of binary libraries, since
1900 I had no doc available).
1901 (append_selection, append_selection_word): Disable with FIXME
1902 since R4 changed interface here.
1903 (create_buttons): Add back the old set of buttons.
1904 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
1906 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
1907 Roll VERSION to 3.94 (not yet final though).
1909 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1911 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
1912 obstack_int_grow, obstack_int_grow_fast): Eliminate
1913 cast on left of assignment, which gives MIPS cc fits and is
1916 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
1917 F_ALIAS. Use printf, not fprintf, when not passing a file
1919 (compare_opcodes): Check that identical instructions have
1920 identical opcodes, complain otherwise.
1922 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
1923 was reported by Roland McGrath.
1924 (unimp): Only match if exactly zero instruction. (Roland)
1925 (branches and traps): Generate all variations of these
1926 instructions with macros, based on a single call that defines
1927 each condition name and its binary representation.
1928 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
1930 * valprint.c (val_print_fields): Take, and use, format parameter.
1931 This means that "p/x struct" again prints the elements in the
1932 desired format. Changed callers.
1934 * stack.c (frame_info): Use filtered output, and indicate wrap
1935 points. Remove kludgy formatting designed to avoid line wrap.
1937 * utils.c (wrap_here): If the line is already full (because
1938 we had printed a long indent or long wrapped string), do an
1939 immediate newline-and-indent.
1941 * m68k-pinsn.c (print_insn_arg): Bugfix from
1942 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
1943 instruction is incorrectly disassembled as bkpt #8.
1945 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
1946 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
1947 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
1948 and then will dump core (sometimes). I traced it back to an
1949 uninitialized symfile_name in psymtab_to_symtab.
1950 (const_vol_complaint): Add quotes to message.
1951 (define_symbol): Only believe line number if gcc_compiled.
1952 Avoid allocating symbol if we will not return it.
1954 Add target strata support so that newly established targets go
1955 into their right place in the target stack (e.g. a new exec file
1956 doesn't wipe out the ability to access the running process).
1958 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
1959 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
1960 and initialize it properly in all the targets.
1962 * target.h: Document strata. Change return type of push_target.
1964 * target.c (nomemory): new function for dummy memory access.
1965 (tcomplain): Rename complain, now also used in symfile.c.
1966 (push_target): Push targets within strata. New return value shows
1967 whether new target is on top of stack or not. Always keep dummy
1969 (target_files_info): Ignore dummy target.
1971 * core.c (core_open): Warn user, and skip accessing file, if the
1972 core target is not the topmost target in the stack.
1973 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
1976 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
1977 target_ops, it doesn't belong there since we have no regs there.
1978 Change name of target from machine => memory to clarify.
1980 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
1982 * Freeze version 3.93 for release.
1984 * Makefile.dist: Handle vx-share and nindy-share subdirs
1985 properly when building gdb.tar.Z.
1987 * symtab.c: lint; add no_symtab_msg to consolidate the messages
1988 printed in various places, so I could change just one copy.
1990 * dbxread.c, coffread.c: Change references to bfd->iostream
1991 to cast to FILE *, now that BFD avoids needing types defined
1992 in other header files.
1994 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
1996 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
1997 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
1998 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
1999 (actually gcc -Wall).
2001 * dbxread.c: Remove first_global_sym, last_global_sym, since
2002 they are never referenced.
2004 * defs.h (baud_rate): Declare.
2005 main.c: Define it, and add the -b option to set it.
2007 * gdb-int.texinfo: Add text on how to define a new host or target
2008 architecture, prompted by Per Bothner's questions about MIPS
2011 * gdb.texinfo: Document "complaints". Change doc of -q since
2012 gdb no longer prints the copyright and blurb if you specify a file
2013 name to be debugged (just like Emacs). Add doc for Nindy-specific
2014 command line flags for specifying target serial port and such.
2015 Update copyright to 1991.
2017 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
2018 has taken over for us the job of ripping up executable files. The
2019 crud caused Per Bothner's port to not compile.
2021 * infrun.c (normal_stop): Avoid printing "Program exited
2022 normally" if we are in batch mode. This allows a GDB which
2023 executes a program on a target system, to behave like a Unix
2024 command (input from stdin, output to stdout, no extraneous
2027 * main.c (main): Allow additional machine-dependent command line
2028 options to be specified with the ADDITIONAL_OPTIONS,
2029 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
2030 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
2031 processing to occur just before the main loop with
2032 BEFORE_MAIN_LOOP_HOOK.
2033 (main): If a "core file" argument is specified, and it is not a
2034 core file, try it as a process ID to attach.
2035 (symbol_completion_function): Attempt to cope with
2036 "show screen-" TAB, not very successfully. This needs more work,
2038 (batch_file): New function, returns whether we are reading
2039 commands from an interactive tty on stdin, or from somewhere else.
2040 Called by normal_stop since it doesn't get from_tty passed down
2041 to it like many commands do.
2043 * remote-nindy.c: Handle command line options for nindy
2045 (nindy_before_main_loop): Prompt user for tty name if they
2046 don't specify it before getting to the interactive command loop.
2048 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
2049 and -r command line options. Also add hook before main loop
2050 to make it easy to specify a tty.
2052 * TODO: More things to do, one done.
2054 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
2056 * dbxread.c: Make complaint() calls pass pointer, not struct.
2057 Add complaints about badly formatted C++ type information
2058 (const/volatile indicator, and parse errors resulting in
2059 error_type). Fix C++ virtual member fn comment.
2060 (read_struct_type): Avoid bumping pointer if we got a parse
2061 error; this prevents our walking beyond the end of a string.
2062 Terminate loop on null char as well as semicolon.
2063 (process_one_symbol): Fix the LBRAC fix so that it uses the
2064 last previous SLINE, FUN, or SO record's PC address. C++ debug
2065 symbols did not have SLINE records in a useful order compared
2066 to the LBRAC records.
2067 (define_symbol): Handle "catch" records.
2069 * symtab.c (check_stub_type): Added new complain
2070 `stub_noname_complain' and added a consistency check to
2071 keep the debugger from crashing when finishing from an
2072 exception frame. A real fix will be needed later.
2074 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2076 * infcmd.c (attach_command): Make global.
2078 * Makefile.dist (REMOTE_OBS): Make these compile by default,
2079 but make them easy to comment out. Perhaps later they should
2080 be enabled by what CPU you configure for? FIXME.
2081 (VERSION): Roll to 3.93.
2082 (pinsn.o): Remove rule for obsolete file.
2083 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
2085 Run down a problem that manifested by printing the wrong function
2086 name in stack traces of read_ofile_symtab. Turned out that the
2087 problem was the SunOS 4.1.1 (and previous) C compiler outputs
2088 the LBRAC symbol with an address in the *data* segment, which
2089 blew our binary search through the blocks.
2091 * dbxread.c: Use the complain() facility consistently to bitch
2092 about problems in the symbol file we are reading.
2093 (finish_block): Add code to check the nesting of the blocks;
2094 complain and Procrust them to fit if wrong.
2095 (make_blockvector): Check the order of the blocks, complain
2096 [but don't cope] if wrong.
2097 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
2098 symbols to be sure their PC value is greater than the last SLINE
2099 (line number) symbol we've seen, complaining and adopting the
2100 SLINE PC value if wrong.
2102 * symfile.h (struct complaint, complaint_root, complain,
2103 clear_complaints): Add.
2104 * symfile.c (complain, complaint_root, clear_complaints): Add
2105 facility to deal with non-fatal complaints and to regularize their
2107 (symbol_file_add): Clear complaint counters to allow new complaints.
2108 (initialize_symfile): Add 'set complaints' and 'show complaints'.
2110 * dbxread.c (dbx_symfile_read): Remember the address and size
2111 of the string table for the main symbol file, so we won't read it
2113 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
2114 to avoid reading the string table yet again. Lint.
2115 (throughout): Improve filtered output, including word wrap.
2116 (read_range_type): Improve Bothner's fix to handle other types too.
2118 * utils.c: Improve line wrap implementation. Handle unlimited
2119 width by making chars_per_line unsigned.
2120 (puts_filtered): New, easy, function.
2122 * defs.h (puts_filtered): add.
2124 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
2125 call the identical sort_symtab_syms() in symfile.c instead.
2127 * expread.y: Suggest the `file' command rather than `symbol-file'.
2129 * command.h (enum var_types): Add zinteger for seroable
2131 * command.c (do_setshow_command): Handle var_zinteger. Restructure
2132 nested if's into a switch.
2134 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
2135 we did not stop because of a breakpoint (it must have been for
2136 some other reason, like a "stepi"), so don't print anything.
2138 * symtab.c: Include <sys/types.h> all the time. Now that BFD
2139 doesn't include <sys/types.h>, old SunOS's require it for
2142 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
2144 A test port of gdb-3.92.6 to the Sony NEWS.
2147 Don't normally link in remote- or vx stuff.
2148 Some of it doesn't compile, and it wastes space for 99% of the users.
2149 Remove reference to no-longer-used HAVE_VPRINTF.
2150 Fixed BFD_DEP typo to BFD_DIR.
2152 Fix cast in arg to bfd_h_getlong.
2153 Make char *prefix be const.
2154 Fix how certain range types are mapped into builtin unsigned int types.
2156 Remove 2 #includes. They cause errors (on Sony, at least),
2157 and aren't needed (they wern't in earlier versions).
2159 print_address_symbolic should never demangle labels
2160 (since it prints *assembler-level* labels).
2162 [This was superseded by the change to printcmd below.]
2165 Add some "volatile" return types to avoid warnings.
2166 If MISSING_VPRINTF add vprintf function and not just macro
2167 (since vprintf is used in printcmd.c).
2169 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
2170 (The latter isn't grokked by some PCC-based compilers.)
2172 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
2174 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
2175 * nindy-share/coffstrip.c
2176 Added some forward declarations (otherwise, gcc complains
2177 about implicit extern redefined as static).
2179 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2181 Changes inspired by Per Bothner:
2182 * printcmd.c (print_address_symbolic): Take additional parameter
2183 specifying whether to demangle.
2184 (print_address): Pass in asm_demangle to control demangling.
2185 (print_address_demangle): New fn, takes explicit arg to control
2187 * utils.c: Add new vars demangle and asm_demangle, and let them
2189 (fputs_demangled): If !demangle, just print the argument.
2190 (fprint_symbol): If !demangle, just print raw symbol.
2191 * valprint.c (val_print): Call print_address_demangle rather than
2192 print_address, to cause demangling to depend on the global
2193 rather than assembler-level demangling setting.
2194 * WHATS.NEW, gdb.texinfo: Document.
2196 * main.c (show_command): Show all settings if no arg.
2197 (initialize_main): Make "info set" the same as naked "show".
2198 * command.c (cmd_show_list): Handle prefix commands in the
2199 list, and print the name of the setting as well as its English
2200 description and value.
2202 Allow gdb functions to specify where a line should wrap if it
2203 exceeds the size of a terminal line. Use it to make the output
2205 * utils.c (set_screen_width_command): New fn, mallocs a buffer
2206 of the right size when screen width changes.
2207 (set_screensize_command, screensize_info): Remove #if 0'd fns.
2208 (wrap_here): New fn, indicates a point in the output where we
2209 should wrap the line rather than just letting it overflow at a
2211 (fputs_filtered): Implement wrapping.
2212 (n_spaces): New fn, returns a pointer to N spaces.
2213 (print_spaces_filtered): Use n_spaces.
2214 * defs.h (n_spaces): Declare.
2215 * stack.c (print_frame_info): Wrap with 4-space indent after
2216 fn name and before filename and line number.
2217 * printcmd.c (print_frame_args): Wrap with 4-space indent
2218 before each argument name is printed.
2219 * valprint.c (value_print): Wrap with no indentation before
2221 (val_print_fields): Wrap with indentation relative to nesting
2222 level before each field name.
2223 (val_print): Wrap with nesting indentation before array elements.
2224 * command.c (do_setshow_command): Avoid extra newlines,
2225 wrap with 4-space indent around values printed, end with period.
2226 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
2228 * breakpoint.c (breakpoint_1): Implement addressprint for
2229 "info breakpoints" display. Change file name and line number
2230 format to " at file:nnn" rather than " (file line nnn)".
2231 * gdb.texinfo: Document.
2234 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2236 Frozen for gdb-3.92.6 release.
2238 README, WHATS.NEW: Update for 3.92.6 release.
2240 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
2241 coffread.o from configs since it is now built by default.
2242 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
2243 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
2244 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
2245 from configs since it is now built by default.
2247 Makefile.dist: Update for release 3.92.6. Handle files that
2248 have been moved to ../include, ../getopt, or ../bfd. Add
2249 saber.suppress and tests directory. Add config.status to
2250 the release (it will say "none").
2252 coredep.c: Minor formatting fixes.
2254 These changes were made in early December but only checked in now:
2255 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
2256 nindy-share/nindy.c: lint
2257 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
2258 register values coming back from the target; we store values
2259 in target byte order everywhere.
2261 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
2263 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
2265 * valprint.c (cplus_val_print, val_print_fields): New functions,
2266 which print C++ objects. They conspire to avoid printing a
2267 virtual base class more than once, following all the twists and
2268 turns of C++ virtual base rules.
2269 (val_print): Call the above rather than do it by hand.
2271 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
2272 symbol file, not for added files like shared libs. This really
2273 needs to be generalized to a timestamp per file.
2275 * core.c (cleanup_core): Avoid coredump if no core file.
2277 * config.gdb: Accept -host or -target in place of +host or
2280 * coffread.c (find_linenos): Avoid desupported BFD interface
2281 to line numbers. We still read them manually rather than using
2282 BFD's "generic" features.
2284 * gdbrc.tex, threecol.tex: Add GDB reference card and its
2286 Makefile.dist: Add refcard to OTHERS list for creating tar files.
2288 * Makefile.dist: Eliminate use of $< in explicit targets.
2290 * readline/Makefile: Use $< rather than $*.c, which does not
2291 include the VPATH in GNU Make.
2293 * tconfig/i960-bout, tconfig/i960-coff: These are identical
2294 copies of tconfig/i960, added for global configuration
2295 compatability. All i960 versions can read both coff and b.out.
2297 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
2298 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
2301 * TODO: Think of more things to do.
2303 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
2305 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
2306 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
2307 64-bit float conversion.
2309 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
2310 equivalent to sun?os4 so global config works.
2312 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
2314 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
2316 * main.c: Only declare linesize once; declare pagesize not at
2317 all, since it is never used.
2318 (main): Clear newly allocated line before it is used.
2320 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
2322 Further stabilization for the Intel 960.
2324 * Makefile.dist: Parameterize the location of the "include"
2325 and "bfd" directories, as well as "getopt". Add symfile.c.
2326 Link in both dbxread and coffread. Fix up "make depend" to
2327 rewack the locations of include, bfd, and getopt in its output.
2329 * README: Document moving include files, improve some of
2332 * coffread.c: Move common code out to symfile.c. Change
2333 symbol_file_command style interface to use new *_symfile_init
2334 and *_symfile_read interface under BFD. Use BFD internal
2335 info to locate line table, symbols, etc.
2337 * core.c (core_fetch_registers): Rename to get_core_registers
2338 to avoid confusion with fetch_core_registers.
2339 (register_addr): Move to coredep.c, which is already machine
2340 dependent. This leaves core.c pretty clean of dependencies.
2342 * coredep.c (register_addr): Accept this routine from core.c.
2344 * dbxread.c: Move common code (with coffread.c, etc) into new
2345 symfile.c. Each psymtab now contains a pointer to the
2346 format-dependent function that knows how to read it in. Make
2348 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
2349 (process_one_symbol): Add code to complain about a "compiler bug
2350 we muzzle here", if we actually see it.
2352 * eval.c (evaluate_subexp): Insert missing "break" statements
2353 in code that determines whether a variable is an lvalue in
2354 memory, register, or whatever. I detected this via a compiler
2355 bug in which it *almost* mashed out the whole switch statement.
2357 * gdb-int.texinfo: Add minor sections on configuring gdb for
2358 release, and about the README file.
2360 * infcmd.c (registers_info): Fix formatting somewhat. Still
2361 not as pretty as before, but it handles byte swapping.
2363 * remote-nindy.c: If data cache routines are interrupted while
2364 waiting for the remote end, be sure that any uninitialized cache
2365 blocks are on the free list, not on the valid list!
2367 * symfile.h: Flesh out this header file with all the various
2368 routines and variables that have been merged in from dbxread.c
2369 coffread.c, and symtab.c to symfile.c.
2371 * symfile.c: New file, containing code common to dbxread.c,
2372 coffread.c, and some code from symtab.c. All generic code for
2373 reading symbol files should be in here now.
2374 (unrecord_misc_function): Remove unused function.
2376 * symtab.h: Remove file-reading things to symfile.h.
2378 * symtab.c: Remove file-reading things to symfile.c.
2380 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
2381 to decode i960 fault types.
2383 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
2384 target.c: Change type of the "resume" function from int to void,
2385 since its result was never used.
2387 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
2389 * main.c: Replace "stupid" with "caution"; you now "set caution
2392 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
2394 * infcmd.c (do_registers_info): Call val_print to deal with the
2395 byte order of the registers being printed. FIXME, this makes
2396 the formatting of the output uglier.
2398 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
2399 defined, call it for signals the debugger doesn't itself use.
2400 The i960 uses this for more detailed fault information.
2402 * remote.c (remote_open): If arg is null, print help rather than
2405 * sparc-xdep.c (register_valid): Avoid declaring size, since
2406 various modules will think of various sizes depending on the
2407 architecture of their tm-file. FIXME, we need protection against
2408 actually entering one of those modules, which would clobber
2409 storage if not for the target architecture compiled into gdb.
2411 * stack.c (up_command, down_command): Always print the frame
2413 (up_silently_command, down_silently_command): New commands
2416 * i960-pinsn.c (reg), i960-tdep.c: Lint.
2418 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
2419 more parameters than it used to.
2421 * findvar.c (registers): Increase slop to 256 bytes, which should
2422 protect us against even most RISC machines with large register
2424 (locate_var_value): Move declaration inside related ifdef.
2426 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
2427 throughout, to avoid throwing away buffered input from the board.
2428 (nindy_wait): Supply_register takes addr_of_value, not value.
2429 (i960_print_fault): Renamed from i80960_fault.
2430 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
2431 (nindy_store_registers): Avoid regs_changed stuff, just stuff
2433 (nindy_create_inferior): Don't bother to write PC_REGNUM since
2434 we can set the PC in the call to proceed(). Unpush nindy_ops
2435 before pushing it on top, to avoid message to user. Eliminate
2436 commentary from Unix machines that just misleads here.
2437 (reset_command): Fix error message to suggest target command.
2439 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
2441 Release 3.92.5 as frozen.
2443 Stabilize the merged release...with help from lint, Saber C,
2446 Everywhere: Add include files needed to declare return types
2447 of functions called.
2449 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
2451 * breakpoint.h: Add undeclared breakpoint functions, and some
2452 functions for display handling since I couldn't think of a better
2455 * breakpoint.c (insert_breakpoints): Make code for disabling
2456 shared library bkpts more likely to work. It's used when we
2457 rerun a program and stop before the shared library has been
2459 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
2460 cast from pointer, so it squeezes through catch_errors.
2461 (bpstat_stop_status): Fix logic broken some time ago. We now
2462 always create a bpstat if the stop address matches a breakpoint,
2463 even if we don't stop there -- just like the old code used to do
2464 before I got my fingers into it (sigh).
2465 (breakpoint_1): Print "ignore count" after "stop only if"
2466 condition, since that's how it actually works.
2467 (mention): Handle watchpoints as well as breakpoints.
2468 (watch_command): use set_raw_breakpoint and mention to do most
2469 of the work (and initialize all the fields!). Only pass one
2470 arg to parse_c_expression, since that's all it takes.
2472 * command.c (not_just_help_class_command): Rename arg to args
2473 since we ignore "unused argument" warnings on vars named "args".
2474 inflow.c (child_terminal_info): ditto.
2475 infptrace.c (kill_inferior): ditto
2476 main.c (catch_errors, version_info, quit_command, pwd_command,
2477 source_command, dump_me_command, editing_info,
2478 set_history_size_command, set_history, show_history,
2480 stack.c (locals_info): ditto
2481 target.c (target_files_info): ditto
2482 valprint.c (set_input_radix, set_output_radix): ditto
2484 * core.c: Remove old variables for handling core and exec file
2485 sections (data_start, data_end, stack_start, stack_end,
2486 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
2487 text_end, exec_data_start, exec_data_end, text_offset,
2488 exec_data_offset, data_offset, stack_offset). They're
2489 superseded the more general build_section_table and
2491 (get_exec_file): Mention the `file' command.
2492 (read_memory_check): Rename to memory_error, and only call it
2493 in the case of an actual error.
2494 (read_memory, write_memory): call memory_error.
2495 (core_fetch_registers): Register section name is ".reg".
2497 coredep.c: Remove a bunch of crud now that all this file does
2498 is pull the registers out of a core file.
2499 (fetch_core_registers): Rewrite to actually work, I hope.
2501 dbxread.c: Use a.out.gnu.h, not system a.out, now.
2502 Replace index() with strchr(). Remove all the pre-BFD macro
2503 definitions for accessing the symbol file.
2504 (struct dbx_symfile_info): Encapsulate the information that
2505 dbx_symfile_init needs to pass to dbx_symfile_read in this
2508 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
2509 dbx_symfile_discard): Rearrange symbol file reading to divide
2510 the format-specific part from the format-independent part,
2511 leaving the format-independent part such as file name expansion
2512 and opening in symtab.c. This replaces
2513 partial_symbol_file_open and partial_symbol_file_read.
2514 Symbol_file_read, add_file, add_file_target_command,
2515 add_file_addr_command move to symtab.c. Pass an explicit
2516 "mainline" flag for when reading the main symbol table, rather
2517 than relying on the offset address to be zero or nonzero.
2519 (dbx_symfile_read): Don't allow void *'s to be printed as
2521 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
2522 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
2523 macro" debug version really work.
2524 (read_dbx_symtab): Remove unref'd parameter inclink.
2525 Avoid swapping N_SLINE symbols, for speed.
2526 Merge N_TEXT!N_EXT case with the other external symbol
2527 definitions' case. Add comments.
2528 (start_psymtab): Allocate the symfile name in the psymtab on
2529 the psymbol_obstack, rather than using the caller's storage.
2530 (end_psymtab): Only allocate a dependencies list if there are
2532 (psymtab_to_symtab_2): Use BFD when reopening file to read
2533 its symbols for real.
2534 (read_struct_type): Add FIXME comments where it needs work
2536 (read_huge_number): Add FIXME about overflows.
2537 (read_range_type): Add FIXME about comparing a long to 1<<32.
2539 * coffread.c: Minor changes to move things closer to the new
2540 regime with symtab.c and dbxread.c Major work is still needed
2543 * exec.c (exec_file_command): Remove old variables (see core.c
2545 (xfer_memory): If memory transfer is right at the end of a
2546 section, don't lose.
2548 * findvar.c (get_saved_register): If value is in a real
2549 register, LVAL is lval_register, not lval_memory.
2551 frame.h: Declare print_sel_frame and record_selected_frame.
2553 gdb-int.texinfo: New file, for GDB internals documentation.
2554 Very simple, unformatted doc of cleanups is there for now.
2556 gdbcore.h: Remove obsolete variables that described a.out
2557 section addresses and offsets. (See core.c above.)
2558 Declare fetch_core_registers and registers_fetched.
2560 getopt.c: Declare char *alloca(); even on SPARC.
2562 infcmd.c (run_command): Call target_kill rather than
2564 (step_command, next_command, stepi_command, nexti_command):
2565 Declare from_tty parameter even though we don't use it.
2566 (run_stack_dummy): argument BUFFER is a char array, not
2567 a pointer to REGISTER_TYPE.
2568 (finish_command): using_struct_return needed a value *,
2569 not a struct symbol *.
2571 * infptrace.c (child_xfer_memory): To avoid dependency on
2572 where sections are in memory, try PT_WRITE_D and if that fails,
2573 try PT_WRITE_I. Most Unixes don't care which you use.
2575 * infrun.c (step_resume_break_shadow): Change to array to
2576 match other breakpoint shadow storage.
2577 (clear_proceed_status): Pass address of bpstat to
2578 bpstat_clear, not the bpstat itself.
2579 (child_create_inferior): FIXME comment about if the child
2581 (start_inferior): Remove old function.
2582 (child_open): Use target_kill rather than kill_inferior.
2583 (wait_for_inferior): Ditto.
2584 (insert_step_breakpoint, remote_step_breakpoint): Use
2585 new step_resume_break_shadow.
2587 * inftarg.c (child_wait): If all child processes die,
2588 pretend that the one being waited for exited with signal 42.
2590 * main.c (command_line_input): When scanning for comments,
2591 don't coredump on unclosed quotes.
2592 (quit_command): Use target_kill rther than kill_inferior.
2593 (_initialize_main): Rename class_user from "user" to
2596 * printcmd.c (print_command_1): Initialize "fmt" if no format
2597 is specified by the user.
2598 (print_frame_args): Only add to args_printed if we are
2599 actually fetching args from the stack (avoiding undefined
2601 (_initialize_printcmd): Remove bogus \{ from string.
2603 * remote-eb.c (eb_open): Avoid coredump on no argument.
2605 * remote-nindy.c: Bring out of Intel environment into new
2606 target environment. Remove all conditional compilation on
2607 I80960. Massive hacking throughout.
2608 (nindy_xfer_inferior_memory): New routine stolen from
2610 (nindy_create_inferior): New routine pieced together, probably
2611 not quite working yet.
2612 (nindy_ops): New target_ops struct for nindy.
2614 * remote-vx.c: Use write_memory rather than target_write_memory
2615 to get error checking.
2616 (vx_add_file_command, vx_open): Use symbol_file_add rather than
2618 (vx_create_inferior): Use target_terminal_ours...
2620 * signame.c (_initialize_signame): Always initialize, since
2621 we need the table for things other than psignal.
2623 * solib.c (solib_add): Use symbol_file_add, not add_file.
2624 (solib_address): Return boolean result rather than struct
2625 pointer which nobody else knows the type of.
2627 * sparc-tdep.c, valops.c: Use write_memory rather than
2628 target_write_memory, to get error checking.
2630 * stack.c (locals_info, catch_info, args_info,
2631 get_selected_block, frame_command, up_command): Use
2632 target_has_stack, rather than have_inferior_p or
2635 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
2637 * symfile.h: New file, defining the interface between the
2638 generic and object-file-specific symbol reading code.
2640 * symtab.c: Move generic symbol-reading interface to symtab.c,
2641 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
2642 table to map BFD targets to symbol-reading modules in GDB.
2643 Change index to strchr.
2644 (lookup_struct_elt_type): Use error() rather than hand-made
2645 simulations thereof.
2646 (lookup_partial_symbol): Speedup slightly when length == 0.
2647 (symbol_file_add): New function.
2648 (symbol_file_command): Call it.
2649 (symfile_open, symfile_init): New function.
2650 (add_file_target_command, add_file_addr_command): moved from
2653 * target.c (target_command): use target_kill.
2655 * target.h (target_files_info): Don't declare, never called
2658 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
2659 files to determine stack end address.
2661 * valarith.c (value_x_binop, value_x_unop): Change error message
2662 to be more useful. Pass proper argument to value_struct_elt.
2664 * valops.c (value_assign): FIXME comment that long long
2665 bitfields will break here.
2667 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
2668 Update `make saber_gdb' to work better.
2670 * TODO: A woman's work is never done.
2672 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
2673 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
2674 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
2675 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
2676 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
2677 valops.c, valprint.c, exec.c: Lint.
2680 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
2682 Continuing Intel 960 port merge of GDB.
2684 * Makefile.dist: Merge i960 "nindy-share" files. Rename
2685 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
2686 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
2687 Wack over "make depend" so it handles files in subdirectories
2688 vx-share, nindy-share, bfd, and in the current directory.
2690 * blockframe.c (get_prev_frame_info): Remove fatal error
2691 if stack not defined.
2693 * core.c (core_open, core_detach): New functions that handle
2694 the old "core-file" command as "target core" and "detach" instead.
2695 (core_file_command): Call them.
2696 (core_xfer_memory): Use common routine xfer_memory.
2698 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
2699 dbxread now uses bfd for everything but symbol reading itself.
2700 BFD internals are used to drag out the relevant file offsets.
2701 (partial_symbol_file_open): Change args all around for BFD.
2703 * symtab.c: Rename "value" to "val" everywhere, so we can
2705 (symbol_file_command): New command, moved from dbxread.c
2706 and coffread.c. It uses BFD to read the file, then vectors
2707 based on its type, to dbx or coff symbol readers.
2708 * symtab.h: Extern a few vars for symbol_file_command.
2710 * target.h: Breakpoint takes a char * save area, not a char **.
2712 * valprint.c (val_print): When unpacking bitfields, offset
2713 the address in gdb of the value, if it is declared with a shorter
2714 type. Remove the last "runtime kludge test" of host byte order.
2716 * utils.c: Remove old my_bfd_read routine.
2718 * stack.c (frame_info): Use target_has_stack. Print program counter
2719 register's actual name rather than "pc", since it's called the
2720 "ip" (instruction pointer) on the i960 (sigh).
2722 * target.c (target_command): Add command for selecting a target
2723 type and calling its open routine. This is used for initiating
2724 communication with a particular target, in a generic way.
2726 * tm-i960.h: Update for modern gdb. Remove semicolons from
2727 various macros. Handle reading struct return convention, and
2728 error-out attempts to return structs with the "return" command.
2729 Be sure gdb doesn't think we know how to call functions in the
2732 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
2733 to i960_xxx in lower case.
2734 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
2735 not being defined yet.
2737 * remote.c (remote_open): Call start_remote to initialize
2738 wait_for_inferior during open.
2739 (remote_xfer_inferior_memory): Return length written rather
2742 * remote-vx.c (target_command -> vx_open): Use new generic
2744 * remote-eb.c, inftarg.c, exec.c: ditto.
2746 * infrun.c: Fix comments.
2747 (attach_program -> child_open): Use new generic target command.
2748 (wait_for_inferior): Clear saved register values before target_wait,
2749 so target_wait can set some of them if convenient.
2751 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
2752 Return success indicator, not void.
2753 (child_xfer_memory): Avoid fetching initial word if we'll
2754 overwrite it anyway.
2756 * infcmd.c (attach_command): Use new generic target open routine.
2757 (_initialize_infcmd): Update doc on attach and detach commands.
2758 (do_registers_info): Merge in a byte-order problem as a FIXME
2761 * findvar.c (find_saved_register): Avoid problem in current frame.
2762 (read_relative_register): Ditto.
2763 (write_register): Convert byte order on the way out.
2765 * exec.c (file_command): Add.
2766 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
2767 (xfer_memory): Common function between core_xfer_memory and
2769 (exec_xfer_memory): Use it.
2771 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
2773 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
2774 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
2775 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
2777 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
2779 Merge Intel 960 port of gdb, continuing...
2781 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
2782 symbol_file_command): Pass from_tty arg to hush 'em up.
2784 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
2785 Add magic numbers for 960 COFF format.
2787 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
2789 Merge Intel 960 port of gdb, from Intel "1.2" release.
2791 CHANGE_LOG entries from their port, which was based on
2794 Thu Sep 6 11:02:22 PDT 1990
2795 Remove temp file if download is interrupted.
2797 Wed Aug 1 09:08:33 PDT 1990
2798 Now uses binary protocol to talk to NINDY.
2799 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
2800 Times out after 5 seconds when trying to talk to NINDY.
2802 Tue May 29 12:54:49 PDT 1990
2803 Added variable baud rate (-b switch).
2804 Source code reorganization.
2806 Thu Apr 26 11:09:55 PDT 1990
2807 More cleanup of batch mode; specifically, execute "-s", "-e", and
2808 "-se" switches as soon as they are encountered on the invocation line.
2810 Fri Apr 20 13:47:15 PDT 1990
2813 Thu Apr 19 09:54:28 PDT 1990
2814 Add 'reset' command.
2816 Wed Apr 18 09:48:07 PDT 1990
2817 After opening remote tty, wait for 1 second to go by without input
2818 from it before trying to talk to NINDY (fixes problems with the
2819 Heurikon HK80/V960E).
2821 Mon Apr 4 16:33:05 PDT 1990
2822 Some output was not being suppressed in 'batch' mode.
2824 Thu Mar 22 15:31:11 PST 1990
2825 Ask user if old symbol table should be deleted when new file is
2828 Allow user to run a program downloaded before gdb960 was brought up.
2830 Correct "exec-file" help message for i80960 context.
2832 Correct bug in calculating user space address: could occasionally
2833 corrupt user program.
2835 Make sure to zero low-order bits in rip's because of bug in 960CA
2836 A-step part: could cause operation faults when "next"ing across
2839 Correct bug that made it impossible to get source line numbers for
2840 code loaded at addresses higher than 0x7fffffff.
2842 Wed Jan 10 12:43:22 PST 1990
2843 Open remote tty for exclusive use.
2845 Fri Jan 5 12:14:42 PST 1990
2846 Correct disassembly (CA manual was right after all):
2847 opcode for sysctl is 0x659
2849 Mon Oct 23 12:03:04 PDT 1989
2850 Use G960BASE and G960BIN environment variables to find 'sx' utility.
2852 Mon Oct 16 14:15:09 PDT 1989
2853 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
2855 Mon Oct 2 15:56:31 PDT 1989
2857 Added 960CA disassembly support.
2859 To simplify maintenance:
2860 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
2862 - eliminated opcode.h: incorporates tables into i960-pinsn.c
2863 - moved 960-specific routines from i960-pinsn.c to i960-md.c
2864 - made disassembly interface identical to that in gdmp960.
2868 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
2870 * target.h: Allow targets to stack. Add target_has_memory,
2871 _registers, etc. Restructure memory access and "info files"
2872 to walk the target stack.
2873 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
2874 target.c: Change tables to match target.h.

2880 * remote-vx.c: New memory regime, new info files. Now use
2881 separate targets for VxWorks attachment to machine, and
2882 actually running a process under VxWorks, since one has
2883 stack & execution & regs and the other doesn't.
2884 * remote.c: New memory regime, new info files.
2885 * sparc-xdep.c (fetch_core-registers): New memory regime.
2886 * target.c: New routines and support for stacked targets,
2887 new memory regime, new info files regime.

2891 including use of the new BFD (binary file) library.
2892 * gdbcore.h: Add struct section_table.
2893 * exec.c (build_section_table): Iterate all sections and
2894 record what gdb needs to know about them.

2901 * dbxread.c: Quick changes to make it compile with new BFD.
2902 * utils.c (error): Avoid using bfd_error in generic routines.
2904 * core.c (core_fetch_registers): Get from the ".regs" section of
2906 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
2908 * inferior.h (attach_flag): Export.
2909 * infcmd.c (run_command): use new target_create_inferior.
2910 * infrun.c (child_create_inferior): Don't return result.

2915 * breakpoint.c (bpstat_num): Handle breakpoints which have
2916 since been deleted, such as temporary breakpoints.
2917 infcmd.c (program_info): ditto.
2919 * core.c (core_file_command): Display the frame where the core
2924 * remote-vx.c (target_command): Merge in target command from
2925 targ-vx.c. A few other cleanups.
2927 * TODO, Projects: Lots more stuff to do...
2929 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
2931 Massive changes to wall off the remote-debugging interface
2932 behind a function vector. The port to handle VxWorks targets
2933 is also part of this.
2935 All files: Replace references to renamed functions,
2936 remove references to remote_debugging, remove references to
2937 have_include_file, have_core_file in favor of target_has_stack,
2938 target_has_memory, etc.
2940 * Modularize the breakpoint interface.
2941 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
2942 a breakpoint instruction.
2943 breakpoint.c: struct breakpoint's shadow_contents now sized as
2945 (insert_breakpoints): Vector to target to install breakpoints.
2946 (remove_breakpoints): Vector to target here too.
2947 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
2948 sparc-tdep.c (single_step): Use new breakpoint interface for
2949 the single-step breakpoints.
2950 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
2951 New file, contains routines to insert and remove breakpoints by
2952 reading out the old contents and later replacing them. This is
2953 how ptrace breakpoints work, and many remote systems as well.
2955 * tm-vxworks68.h: New config file, overrides a few things for
2956 Wind River's preferences.
2958 * target.h: New file, for transfer vector used to talk to the
2959 inferior (child, attached, core, exec, remote, etc). All accesses
2960 to the thing being debugged should come through these vectors.
2961 target.c: New file, routines to handle transfer vector.
2962 (various files): Add transfer vectors XXX_ops for the various
2963 targets and pseudo-targets (core files, etc) we support.
2965 * breakpoint.c (bpstat_stop_status): Further explorations of
2966 watchpoints and why things don't work all the time.
2967 (bpstat_alloc): New fn to allocate a bpstat and chain it.
2969 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
2970 the local gdbinit if it doesn't already have it.
2972 * core.c (core_ops): add and install.
2973 Allow core debugging without exec file.
2975 * dbxread.c (free_and_init_header_files): Merge two fns.
2976 (end_symtab): Free named symbol table when a new version comes in.
2977 (read_dbx_symtab): Relocate all kinds of symbols with base
2978 address. First step toward handling different text, data, bss
2980 (add_file_addr_command): Renamed add_file_command.
2981 (add_file_command): Vector to remote handler.
2982 Add "load" as an alias for "add-file" command.
2984 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
2985 non-returning functions.
2987 * exec.c: Add exec_ops, and push it as a target when an exec
2990 * infcmd.c (run_command): Pass executable file name and arg list
2991 separately when starting an inferior. Permit "run" when no exec
2992 file is specified, for VxWorks.
2993 (detach_command): Move to child_detach in inftarg.c.
2995 * inftarg.c: New file. Unix-child-specific routines, and the
2996 child_ops structure.
2998 * inferior.h (registers): Export "registers" as the way for
2999 target dependent register handlers to find gdb's local copy of
3000 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
3001 since it is now used by places that want wait_for_inferior to
3002 handle the grunge but want to see every trap from the inferior.
3004 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
3005 Eliminate remote_debugging hooks in terminal handling.
3007 * infrun.c: Replace start_inferior with child_create_inferior.
3008 Move all the hair of Unix shells and ptrace idiosyncracies into
3009 child_create_inferior, so remote handlers don't have to deal.
3010 Remove running_in_shell. Rename stop_after_attach to
3011 stop_soon_quietly, and use it in a few other places where we want
3012 to just call wait_for_inferior and get control back on the first
3013 trap. trap_expected now never takes a value > 1.
3014 (init_wait_for_inferior): Initialize static vars when a new
3017 main.c (gdbinit): Add new hook for .gdbinit file name, let
3018 it be overridden by config files as GDBINIT_FILENAME.
3019 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
3020 Both of these are used for VxWorks gdb.
3022 mcheck.c: rename include file "gmalloc.c" to avoid problems
3023 with system include file "malloc.c".
3025 param-no-tm.h: New include file, same as param.h but does not
3026 include the default "tm.h" file. This is used in files where
3027 the target is known, e.g. remote-eb.c or sparc-xdep.c.
3029 param.h: Now just a shell that includes tm.h and param-no-tm.h.
3031 remote-vx.c: New file, VxWorks remote debugging support. Uses
3032 RPC routines that are shared with the target system, in directory
3035 remote.c: Vectorize remote interface.
3037 source.c: Globalize source_path, and make an alias "l" for "list"
3038 since we now have the "load" command.
3040 sparc-xdep.c: Use new param-no-tm.h.
3042 symmisc.c (free_named_symtab): Add new function from Wind River.
3043 However, ifdef it out for now while we think about what it should
3046 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
3048 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
3049 non-Unix-children handle this with their own code in the target
3052 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
3053 source and target lists. Add vx-share to default list of include
3054 directories. Add new files to src and target lists: mem-break,
3055 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
3056 ${srcdir} versions of munch and createtags are used.
3058 * valops.c (find_function_addr): Split out of call_function.
3059 (call_function_by_hand): Rename call_function; this function
3060 calls functions in the target by laboriously patching the target
3061 word-by-word with the right stack, args, regs, etc.
3064 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
3066 Handle AMD 29000 a bit better.
3068 * remote-eb.c (readchar): Mask received char log to make it readable.
3069 (remote_start): Pass arguments down to executing program.
3070 Make startaddr unsigned.
3071 infrun.c (start_inferior): Accept args, pass them to
3073 infcmd.c (run_command): Pass args down to start_inferior.
3075 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
3076 the target object file format.
3077 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
3079 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
3080 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
3082 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
3084 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
3085 * TODO: We did a few things, we have more to do though.
3087 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
3088 * inflow.c (inferior_died): Clear deferred stores.
3090 * Debug problems with dummy frames and calls to the inferior.
3091 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
3092 * sparc-tdep.c (do_restore_insn): Simplify.
3093 (sparc_frame_find_saved_regs): Simplify and fix what we find.
3094 (sparc_push_dummy_frame): Simplify and fix what we push.
3095 (sparc_pop_frame): Slightly more hair here, deciding whether
3096 we are restoring a saved PC or returning to a return address in %i7.
3097 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
3099 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
3100 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
3101 * obstack.h (chunkfun): ditto.
3102 * defs.h (xmalloc, xrealloc): ditto
3104 * utils.c (quit): Grab the terminal from the child if necessary.
3106 * inflow.c (term_status_command): Rename to term_info, change
3109 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
3110 (is_delayed_branch): Speed up.
3111 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
3112 Still missing some float ops, and needs testing.
3114 * Support for input and output radixes other than base 10
3115 * defs.h (input_radix, output_radix): Declare.
3116 * expread.y (yyparse, parse_number): Handle changes of input
3117 radix, and ambiguous names-or-numbers in radixes >10.
3118 * printcmd.c (print_scalar_formatted): Print formatted hex
3119 numbers in varying column widths.
3120 * valprint.c (val_print): Use output_format to print scalar ints.
3121 (set_input_radix, set_output_radix, set_radix): Create.
3122 (set_output_radix): Set output_format from output_radix.
3123 (_initialize_valprint): add `set radix' but leave the others off.
3125 * main.c (execute_command): Let stupid questions be turned off.
3126 (_initialize_main): Handle "set stupidity", etc.
3128 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
3129 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
3131 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
3133 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
3134 bfd stuff is still screwed up, but with some manual work, it
3137 * breakpoint.c (bpstat_do_actions): Start over if a command
3138 proceeds the inferior, since the inferior will have stopped and
3139 will need to have its new stop-actions taken care of.
3141 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
3142 compiler fits, simplify it.
3144 * gdb.texinfo (directory command): Doc new dir command.
3145 source.c (directory_command): "dir" now puts things on the front
3146 of the path, moves dups up front, and handles multiple names
3147 on the command line, inserting each one in order. It also
3148 blows away cached line and full_filename info.
3150 * stack.c (backtrace_command): Skip "more stack frames follow"
3153 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
3154 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
3155 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
3156 The only odd one was Gould NP1, which had defined vprintf to
3159 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
3160 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
3161 variable, inspect_it.
3162 valprint.c (print_string, val_print): Use the global inspect_it
3163 to indicate whether to print in Epoch style or normal style.
3165 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
3167 * printcmd.c (call_command): add an alias for the "print" command
3168 which runs expressions and doesn't print the result if void.
3169 (print_command_1): implement it.
3171 * command.c: Remove #if 0'd code. Initialize all the fields
3172 in add_cmd (). Rename do_nothing_command to
3173 not_just_help_class_command, and make it externally visible.
3174 command.h: add user_commands to struct.
3175 * main.c (define_command): Don't overload c->function with a char
3176 string as well as a function pointer.
3178 * eval.c (evaluate_subexp): Reinstall tiemann changes to
3179 calling convention of value_struct_elt () that got dropped in
3182 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
3183 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
3185 * tm-sparc.h (POP_FRAME): replace some constants with defines.
3187 * sparc-xdep.c (store_inferior_registers): defer stores to regs
3188 until a good time (e.g. when we are about to run the child),
3189 saving ptrace calls.
3190 * infrun.c (proceed): handle DO_DEFERRED_STORES.
3191 * tm-sparc.h: define DO_DEFERRED_STORES.
3193 * sparc-xdep.c (store_inferior_registers): when storing float
3194 registers, don't store stack regs too. When storing the SP,
3195 however, DO store the stack regs too. This fixes a bug in which
3196 the dummy frame is not recognized when a call_function finishes,
3197 because its frame pointer (in the stack regs) was never
3199 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
3200 even though we don't know how to read them from an inferior.
3201 valops.c (call_function): Comment about storing SP.
3203 * infrun.c (save_inferior_status): Save away the original bpstat
3204 chain so it can be restored later. Install the copied version for
3205 use by whoever saved the status. It will be blow away by
3206 restore_inferior_status, and the original chain restored. This is
3207 important for people who have pointers into the original.
3209 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
3210 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
3211 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
3214 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
3216 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
3217 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
3218 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
3220 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
3222 * Merge Mike Tiemann's multiple inheritance changes from Sun.
3223 Store the baseclasses in a type struct starting from array element
3224 0 rather than from the unusual array element 1.
3226 dbxread.c: the above.
3227 (virtual_context): Add
3228 Read new debug information about which virtual function table
3229 a virtual function is from, and store it in fn_field.fcontext.
3231 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
3232 TYPE_FN_FIELD_STATIC_P.
3234 symtab.c: the above.
3235 valops.c: the above. Handle pointer casts of object *'s.
3236 (search_struct_method): Add.
3237 (value_struct_elt): First arg is now a pointer to a value, and is
3240 valprint.c: the above.
3241 values.c (value_virtual_fn_field): Add type arg. Handle
3242 offsetting to the proper object when calling virtual fns.
3244 (baseclass_addr): Add valuep arg.
3246 * README: Document the current state of BFD config (missing).
3247 * TODO, ChangeLog, Makefile.dist: Roll version.
3248 * WHATS.NEW: Add summary of changes since 3.5.
3250 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
3252 * dbxread.c (read_struct_type): Clear bit vectors whenever
3254 symtab.c (B_CLRALL): define.
3256 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
3257 using == rather than =. Huh... This fixes the dreaded problem
3258 wherein builtin_type_int becomes TYPE_CODE_FLT.
3260 * core.c (info_files): Show the inferior pid.
3262 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
3263 already knows how to look in the source directory.
3265 * Remove psymtab hair from many places. Remove duplicated code
3266 for searching symbol tables. Hide psymtabs from most places.
3267 Make it fast to get from a psymtab to its symtab.
3269 blockframe.c (blockvector_for_pc): Remove psymtab hair.
3270 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3271 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
3272 dbxread.c: export psymtab_to_symtab, make it work if called N times.
3273 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
3274 new symtab completely. New psymtabs get symtab pointer
3275 initialized to zero. Remove MI warning printf.
3276 symtab.h: Comments. Add psymtab to symtab pointer.
3277 (PSYMTAB_TO_SYMTAB): New macro.
3278 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
3279 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
3281 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
3283 (print_frame_info): Avoid special-casing symbols that have not yet
3286 * source.c (open_source_file): Quick path if we have already
3287 located the source file by its full name.
3289 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
3290 find_pc_psymtab. When a name is found in the misc function
3291 vector, search the symbol table for its mangled name, not the
3292 name that the user typed.
3294 * bfd.h: Fix missing comment terminators, make #endifs match.
3296 * valarith.c (value_less): Handle unsigned int comparisons.
3297 Add FIXME about pointer compares, which assume host and target
3298 pointers are the same.
3300 * command.c (do_nothing_command): lint
3301 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
3302 fix comments on debug symbol format for visibility. Actually set
3303 visibility of symbols.
3304 main.c (echo_command): lint; use <readline/history.h>.
3305 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
3306 obstack.h (_obstack_blank): Rearrange pointer math to avoid
3307 pointing past end of allocated memory; saber complains.
3308 obstack.h: Declare the external functions that we use.
3309 valarith.h: use <string.h>
3310 solib.c (solib_add): lint.
3312 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
3314 * main.c (initialize_main): Default info_verbose to off, now that
3315 symbol reading is fast.
3316 (quit_command): Avoid clobbering exec_bfd while quitting.
3318 * Initial BFD (binary file diddling library) merger:
3319 coffread.c: Change AOUTHDR to struct exe_hdr.
3321 core.c: initialize initialized data at compile time.
3322 (core_file_command): Move from coredep.c, convert to bfd.
3323 (xfer_core_file): Convert to bfd.
3324 exec.c (exec_file_command): use bfd routines.
3326 mips-tdep.c: Remove exec_file_command and friends.
3329 * coredep.c: (fetch_core_registers) Convert core_file_command to
3330 fetch_core_registers.
3331 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
3333 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
3334 (my_bfd_read): More bogosity, which I don't think we call.
3335 (program_name): Remove this atrocity asap!
3337 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
3340 values.c: allocate_repeat_value was not clearing the
3341 optimized_out field.
3342 (value_static_field): minor stylistic fix (wrong macro was used).
3343 valops.c (value_struct_elt_for_address): didn't work for C++
3346 * signame.c (_initialize_signame): Initialize signal names once.
3348 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
3349 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
3350 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
3352 * remote-eb.c: Support user-settable baud rates on the serial port.
3354 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
3356 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
3358 * tconfig/sun3os4: Remove warning about native assembler,
3359 since it also occurs in the xconfig file.
3361 * findvar.c (registers): Allocate some slop after `registers'
3362 to prevent stray accesses from trashing the next variable.
3364 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
3365 on the sun-3, by changing the #ifdef from `sun3' (which is not
3366 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
3367 vars, which happened to follow `registers' in the executable.
3369 * readline/history.c (history_search): Heed gcc-2's advice
3370 and parenthesize && inside ||).
3372 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
3373 tm-29k.c: Insert FSF copyright headers.
3375 * remote-eb.c: Better comments.
3377 * Makefile.dist: Update to 3.91.6.
3378 * TODO: note PREPARE_TO_STORE problem.
3380 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
3382 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
3384 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
3386 * infrun.c (wait_for_inferior, at end): Don't set up
3387 prev_* if the inferior no longer exists.
3389 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
3390 CANNOT_EXECUTE_STACK.
3391 valops.c (call_function): Use it.
3393 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
3395 * inferior.h (PC_IN_CALL_DUMMY): New macro.
3396 infrun.c (wait_for_inferior, 2 places): Use it.
3398 * values.c (value_being_returned): Only use
3399 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
3401 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
3402 right thing for remote-eb.c.
3404 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
3405 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
3407 * blockframe.c: Put get_frame_saved_regs inside #if !defined
3408 (FRAME_FIND_SAVED_REGS).
3410 * findvar.c ({fetch,store}_registers): Check for
3411 REMOTE_{FETCH_STORE}_REGISTER macro.
3413 * findvar.c (get_saved_register): Add argument lval and
3414 change meaning of argument addr.
3415 findvar.c: Change calls to get_saved_register to reflect
3416 new calling convention.
3417 valops.c (value_assign): Use get_saved_register instead of
3418 find_saved_register.
3420 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3422 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
3423 an (uninitialized) pointer to one. Use "&" when passing it
3426 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
3428 * coffread.c (getfilename): Use DGUX x_offset and x_name if
3431 * coffread.c (symbol_file_command): Put semicolon after
3433 Put safe_to_init_tdesc_context in #if defined (TDESC).
3434 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
3435 coffread.c: #include <sys/stat.h>.
3436 (read_coff_symtab): Typo: in_source_files -> in_source_file.
3437 Add missing ')' in check for "lc%" and friends. Remove
3439 Declare read_one_sym() at top of file.
3440 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
3441 MC68WRMAGIC can have the same value without causing a duplicate
3444 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
3446 * Allow a Makefile to be built without building the
3447 tm and xm file links that screw up builds in subdirectories.
3448 This is done with `config.gdb none', then you can do things
3449 like `make gdb.tar.Z'.
3450 * tconfig/none: Config file for no target system
3451 * xconfig/none: Config file for no host system
3452 * config.gdb: If no TM or XM files are called out by the
3453 host or target file, don't make links for them.
3455 * cplus-dem.c: Add documentation.
3457 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
3458 simple error, so the user's gdb doesn't crash due to some object
3459 file problem (e.g. somebody is rebuilding the file out from under
3462 * printcmd.c (print_address_symbolic): demangle the symbol.
3464 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
3465 Motorola copyrights in it. Make "make gdb.tar.Z" work.
3466 (alldeps.mak): sort and uniq all results from this; duplicates
3467 hose gdb.tar.Z link building. Remove RCS files from
3468 tconfig and xconfig. Add config files for sun386. Add
3469 a few odd files to OTHERS and HFILES.
3471 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
3473 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
3474 Roll version number to 3.91.5. Make lint work in bindir.
3476 * README: Document cross-debugging and new file structure.
3478 * blockframe.c: Lint. Include "value.h" to declare read_register.
3479 (find_pc_partial_function): remove duplicate line.
3481 * command.h: Lint. Declare error_no_arg and dont_repeat.
3483 * tm-news.h: Remove inadvertently duplicated stuff.
3485 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
3486 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
3488 * config.gdb: Allow `config.gdb host target' form. Clean
3489 up previous change that printed bogus messages when you just said
3492 * core.c: #include "command.h" for lint.
3495 * main.c: Remove some casts of enums. Lint.
3502 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
3504 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
3505 read it from memory. This will allow us to save ptrace calls
3506 eventually. Changed caller single_step too.
3508 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
3509 that we aren't going to use, saving many ptrace calls, especially
3510 when watchpointing or single stepping. Use some #define's for
3512 (store_inferior_registers): Ditto.
3513 (core_file_command): Use some #define's for constants.
3515 * tm-sparc.h: Add #define's for some register numbers, so we
3516 can eliminate the use of random constants in sparc-xdep.c.
3518 * stack.c (frame_command, print_frame_info, up_command,
3519 down_command) Remove frame_changed, since it
3520 causes a bug and doesn't seem to do anything useful. In some
3521 places it was used as a flag, in others as a stack level (?).
3523 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
3524 default is to use the portable (vprintf) version rather than the
3526 * xm-news.h (MISSING_VPRINTF): Add.
3528 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
3530 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
3532 * Remove stuff that forces -Bstatic linking of gdb, and warnings
3533 about linking debugged programs -Bstatic in the sun?os4 config
3534 files in tconfig and xconfig subdirectories.
3536 * main.c (main): Remove unreached exit(0) now that we exit
3539 * Create TODO file for online bug list. There are too many
3540 "little" bugs to keep track of on paper.
3542 * Change Projects file to refer to bug-gdb@cygnus.com
3543 rather than kingdon@ai.
3545 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
3547 * Makefile.dist (VERSION): 3.91.4 now.
3549 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
3550 (condense_misc_bunches): Add sanity check that misc_count is
3551 the same as the number of symbols in the bunch.
3553 * coffread.c: rename init_misc_bunches. Pass an argument
3554 to condense_misc_bunches (a zero).
3556 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
3557 every time we are called; don't rely on our caller to do it.
3558 (add_file): Remove call to init_misc_bunches.
3560 * mipsread.c: Only warn, don't error, if unknown symbol types.
3561 This keeps an old gdb from falling on its face if it sees newly
3562 extended symbol info. Rename init_misc_bunches.
3564 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
3566 * Merge in changes from Per Bothner for DECstations and other
3567 MIPS stuff. The rest is Bothner speaking:
3569 The next message is a merger of Alessando Forin's mips port with
3570 mine. I've tried to use my good if biased judgment to get
3571 the best of both. It *does* need testing.
3573 Some of the changes are general, *not* mips-specific.
3576 Didn't believe in little-endian bit order.
3577 There are still inconsistencies about whether flags
3578 like BITS_BIG_ENDIAN are integer (#if ...) or
3579 boolean (#ifdef ...). I tried to paper over them.
3581 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
3582 Moved some misc_function code that was common to
3583 {dbx,coff,mips}read.c to symtab.c.
3584 In the process, I think I cleaned things up a bit.
3585 At the same time, moved obsavestring and obconcat to symtab.c.
3588 Removed obsolete condense_addl_misc_bunches (use
3589 condense_misc_bunches(1) instead).
3592 Needed to include <sys/dir>, at least on DECstations.
3594 valops.c, mips-tdep.c, tm-mips.h:
3595 Added PUSH_ARGUMENTS macro to support funny argument-pushing
3596 conventions (when STACK_ALIGN is insufficient).
3597 Needed on mips, where doubles need 8-byte alignment,
3598 but ints only need 4.
3601 Removed cruft that was not being used.
3602 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
3605 Print $ before register-names (I think that makes things a little
3607 Never print two instructions, even if one delays.
3608 Removed hex-disassemble set_cmd. (This is not mips-specific,
3609 so I think the argument is whether it is generally worthwhile or not.
3610 I'm inclined to think not, given how easy it is to
3611 convert between radixes in gdb.)
3614 This is basically Alessando's code.
3615 It doesn't use obstacks; I changed it to use obstacks
3616 in a few minor places where using malloc causes a
3617 memory leak. (Probably, more places could/should be changed.)
3618 I added record_misc_function where it was missing.
3619 In symbol_file_command and add_file_command, I tried
3620 to make the code consistent with more recent versions.
3621 Minor sylistic changes in parse_procedure.
3622 Make a .gdbinfo. psuedo-symbol point back to the real
3623 procedure symbol (using the isym field).
3626 This is basically from my port, but with a lot of details
3627 and a number of routines merged in from Alessando's version.
3628 I basically used my code "raw" backtrace (use heuristics
3629 from the actual code, rather than symbol table info) - though
3630 the idea is Alessandro's. I feel my code is a little cleaner
3631 here, particularly in being a little more flexible, such as being
3632 able to handle gcc-produced code (which it now can).
3633 It also doesn't do frame caching (which is not useful
3634 more recent gdb versions).
3635 I also used my code for push_/pop_dummy, more or less.
3636 I tried to incorporate AF's code for testing sigtramp
3637 while backtracing; I probably got it wrong.
3638 Added mips_print_register, which tries to scrunch as much
3639 information as possible on a screen...
3640 Removed the skip-prologue set_cmd. As with hex-disassemble (see
3641 under mips-pinsn.c), I don't see anything mips-specific here,
3642 and I don't see it being all that useful anyway.
3645 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
3646 Use more register names (rather than hard-cases numbers).
3648 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
3650 * Hack up 3.90.11 changes:
3652 * Makefile.dist (depend): parameterize $(GCC).
3653 Add solib.c and solib.o.
3654 (readline): Fix vpath for both absolute or relative SRCDIR.
3656 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
3657 Also, let the part I didn't understand at least compile so
3658 I can test the rest. FIXME.
3660 * dbxread.c: Fix thinko using strcmp.
3661 (init_psymbol_list): declare static.
3662 (partial_symbol_file_open): Comment cleanups better, avoid
3663 cleaning up the string table since the caller will do that.
3664 Move the stat for mod time into symbol_file_command, temporarily.
3665 (There should be a mod time for each symbol file, eventually,
3666 to control its rereading. FIXME.)
3668 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
3669 SunOS, which gives error for shared libs otherwise. (From
3670 Schaefer, probably FIXME needs work for portability.)
3672 * solib.c: Move #include "param.h" to work.
3673 Lowercase all the Uppercase Letters In the Messages.
3674 (find_solib): Clean up inferior_so_name for debug printouts.
3675 Allow no argument, to mean all shared libraries.
3677 * symmisc.c: include param.h to get CLEAR_SOLIB.
3679 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
3681 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
3682 to 3.90.11. ChangeLog entries below are from this.
3684 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3688 * Makefile.dist (HFILES): Add tm-sunos.h.
3690 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3694 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
3696 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
3698 * sparc-opcode.h Added single-operand version of rett.
3700 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3702 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
3703 Put parens around gcc_p in expansion.
3705 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
3707 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
3709 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3711 * Changes for Sun shared libraries:
3712 blockframe.c (find_pc_partial_function): If a non-text symbol
3713 is found, set *address = pc - FUNCTION_START_OFFSET.
3714 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
3715 Disable breakpoints instead of giving an error.
3716 source.c (select_source_symtab): Initialize cs_pst.
3717 symmisc.c: Call CLEAR_SOLIB if defined.
3718 symtab.h: Make text{low,high} CORE_ADDR not int.
3719 (psymtab): New field addr.
3721 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
3722 (record_misc_function): Give correct type for N_DATA symbols.
3723 (condense_misc_bunches): do "misc_function_count = j" regardless
3725 Take code which is shared between symbol_file_command and
3726 add_file_command and put it into partial_symbol_file_{open,read}.
3727 Split add_file_command into add_file_command and add_file.
3728 Make psymtab_to_symtab read in the string table if the file
3730 Two new parameters to read_dbx_symtab and start_psymtab.
3731 tm-sunos.h: New file.
3733 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3735 * infcmd.c: Change cont_command to continue_command and "cont"
3738 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3740 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
3742 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
3744 * values.c (USE_STRUCT_CONVENTION): Check for structures of
3745 size 1,2,4,8 rather than size < 8.
3747 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
3748 as necessary, not just once.
3750 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
3752 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3754 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
3756 * tm-news.h: Add CALL_DUMMY_*.
3758 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
3760 * config.gdb: In list_host, list_target, use ${i}, not $i.
3762 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3764 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
3766 * sparc-opcode.h: Change all store floating-point state register
3767 instructions to have the right match & lose fields.
3769 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
3771 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
3773 config.gdb: If srcdir != ., create readline directory and
3774 copy a makefile into it.
3776 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
3777 consistency with POSIX.
3779 * breakpoint.c (bpstat_stop_status): Disable watchpoint
3780 when we exit its exp_valid_block.
3782 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
3784 * Makefile.dist: Bump version to 3.91.3.
3786 * Clean up handling of breakpoint commands (somewhat).
3787 Prompted by Tiemann bug report "cont 10" doesn't work any more.
3789 inferior.h: Add breakpoint_proceeded to inferior status struct
3790 and globals; save it and restore it.
3791 (clear_breakpoint_commands): Cleanup, remove old #define.
3793 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
3794 (save_inferior_status, restore_inferior_status): handle it also.
3795 (proceed): Remove earlier code that set breakpoint_proceeded.
3796 It is now set only in clear_proceed_status.
3797 (clear_proceed_status): Cleanup, use bpstat_clear rather
3798 than clear_breakpoint_commands. No callers need the stop_bpstat
3799 between clear_proceed_status and proceed.
3801 infcmd.c: Add breakpoint_proceeded definition and comment.
3802 (cont_command, jump_command, signal_command): Move call to
3803 clear_proceed_status right next to call to proceed.
3805 breakpoint.c (bpstat_do_actions): Avoid clobbering our
3806 caller's argument while running down the chain of breakpoints.
3807 Use new variable "breakpoint_proceeded" to determine when
3808 a command that it executes moves the inferior past the
3810 (bpstat_clear): Handle NULL argument.
3811 (bpstat_clear_actions): Avoid useless call to
3812 breakpoint_auto_delete.
3813 (delete_breakpoint): Clean up bpstat's that are pointing to
3814 the deleted breakpoint from the stop_bpstat chain.
3815 (breakpoint_auto_delete): Simplify.
3817 * Clean up handling of EOF, error on stdin, etc. This was
3818 prompted by a network problem that caused gdb to go into an
3819 infinite loop filling up its malloc'd memory.
3821 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
3822 not clear_breakpoints_commands, which is now gone.
3823 (main): If command_loop returns (e.g. from EOF on stdin), do
3824 a quit_command (looping back to command_loop if quit_command
3825 doesn't really quit).
3826 (command_loop): check result from command_line_input and
3827 exit if it returns NULL, rather than passing the NULL to
3829 (gdb_readline): Free malloc'd result space before returning
3832 * utils.c (query): Handle C-d to mean "yes", just as if the
3833 input was not a terminal. Also avoid infinite loop if EOF
3834 occurs in mid-input-line before newline. This allows
3835 query to be used at EOF on stdin with reasonable results.
3837 * infrun.c (proceed): Set breakpoint_proceeded.
3839 * values.c (value_as_long): Avoid infinite recursion for enums.
3840 (_initialize_values): Fix typo in help msg (kingdon).
3842 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
3843 RL_LIB for linking. This allows -lreadline for linking
3844 and nothing for dependencies, once readline is a real library.
3846 * config.gdb: Jim Kingdon: give useful error message if the
3847 host or target type is not recognized.
3849 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
3850 it just defines it. Dumb, but deal with it.
3852 * Jim Kingdon suggests:
3853 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
3855 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
3857 * Makefile.dist (VERSION): Bump version # to 3.91.2.
3859 * Clean up Bothner's changes.
3861 * blockframe.c (clear_pc_function_cache): New function.
3862 * blockframe.c: remake cache_pc_function_* static.
3863 * dbxread.c (symbol_file_command): remove references to
3864 cache_pc_function_* variables.
3865 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
3866 * printcmd.c: Avoid kludging a global variable (addressprint)
3867 to avoid printing the address of a string twice. Instead,
3868 pass the format letter 's' down low enough that it can be seen
3869 to avoid this problem.
3870 (print_formatted): Pass format arg to value_print.
3871 (restore_addressprint): Remove function.
3872 (do_examine): Avoid hacking addressprint, cleanups and such.
3873 (print_frame_args): Add a comment to a Bothner change.
3874 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
3875 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
3876 to wipe out the values cached in blockframe.c.
3877 * symtab.c (find_method): Add comment saying how big you must
3878 allocate to be "big enough". Per being terse again.
3879 * valprint.c (val_print): Handle format letter "s" to print
3880 strings without addresses. Add comment to vtbl printing code
3881 which casts with wild abandon. Rearrange reference-printing
3883 @0xaddr: value (print w/addressprint)
3884 value (print w/~addressprint)
3885 @0xaddr (parameter lists w/addressprint)
3886 or nothing (parameter lists w/o addressprint)
3888 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
3890 * Merge more changes from Per Bothner:
3892 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
3893 annoying) that I tried to improve it. Here are my suggestions.
3895 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
3898 Do automatic de-reference when taking the address of a reference.
3900 Don't deref_ref when printing parameter lists.
3902 More attempts at treating refernences properly.
3904 In val_print, if deref_ref==0, don't print dangling " = ".
3906 Add COERCE_REF macro, which de-references an REF.
3908 * Merge changes from Per Bothner:
3910 * Fixed (Sony news)-specific configuration problems.
3911 * Fixed other problems with using vanilla pcc and libc (enum problems;
3912 assumption that vsprintf exists).
3913 * Some major speed-ups (finc_pc_partial_function now caches a match;
3914 parsing avoids duplicate symbol_lookup calls).
3915 * Changed handling of baseclasses (no longer use baseclasses field
3916 of struct type, use the first n_baseclasses fields instead).
3917 * Various minor changes/fixes, most C++-related.
3920 Cache the most previous match from find_pc_partial_function.
3921 (Save both low and high ends of matching function's pc range.)
3922 This speeds up the loop of infrun.c:wait_for_inferior quite
3923 a bit, and makes step/next commands much zippier.
3925 Added an enum->int cast (otherwise, some compilers barf).
3927 No longer set baseclass offset to 0, since multiple
3928 inheritance now mostly works.
3929 Added a number of casts, to shut up compiler warnings
3930 (after stabs where made enums, not ints).
3931 When discarding a symbol table (in symbol_file_command),
3932 must clear the cache introduced in blockframe.c.
3933 Don't convert $vtbl_ptr_type to vtbl any more.
3934 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
3935 Mask off sign bit emitted by g++ for virtual table offset.
3936 Set voffset to -1 (not 1) for static member functions.
3938 Changed parsing/lexing of names to avoid doing symbol lookup twice
3939 (once when lexing to determine symbol class, once for real).
3940 Now only call symbol_lookup once. Fields of 'this' win especially big.
3942 Subpress printing addr twice in the case of 'x/s addr'.
3944 lookup_basetype_type is no longer used.
3945 Add find_methods as recursive helper function to decode_line_1.
3946 This allows multiple inheritance to work.
3947 Also, once one or more matches has been found, do not look in
3948 base-classes. (Baseclass methods would be overridden, anyway.)
3950 Removed baseclasses array in struct type.
3951 Instead of using baseclasses[i], use fields[i-1].
3952 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
3953 Changed sign convention of voffset (previous was inconsistent).
3955 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
3957 Used to assume existence of vsprintf. Re-written to not need it
3958 if HAVE_VPRINTF is undefined.
3960 typecmp was too pessimistic. Made it less so.
3962 Don't print space after address.
3963 If vtable points to a misc symbol (with 0 offset), print it,
3964 since that indicates the actual class of the object.
3965 Changed ype_print_derivation_info to use new inheritance
3966 scheme (without baseclasses vector).
3968 In value_primitive_field, fixed some bugs left over from previous set of fixes.
3969 Also, changes needed because TYPE_BASECLASSES were removed.
3971 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
3973 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
3976 If there is no path set, and the symbols don't indicate what directory
3977 a file was compiled in, look in the current directory. But either
3978 a path or a known compilation directory will prevent this.
3981 Three independent bug fixes:
3982 * Remove the #if 0 block that breaks some stuff.
3983 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
3984 adapt gdb to either SunOS 4.0.* or 4.1.
3985 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
3988 Instantiate the class T when looking for methods in it. (Tiemann@sun)
3991 (type_print) Demangle the name being printed.
3992 (type_print_base) Handle botched demangling without coredump (tiemann).
3995 (check_stub_method): Document routine.
3996 (tiemann) fix bug for no-arg functions
3997 Avoid clobbering beyond end of malloc'd storage.
3998 Terminate the argument list properly.
4000 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
4002 * Changes merged by John Gilmore:
4005 In breakpoint_1, use new print_address_symbolic instead
4006 of find_pc_partial_function. (This forces use of assembler-level
4007 addresses, and avoids misleading non-mangled source-level names.)
4009 Generalize ansi argument such that -1 means skip arglist totally.
4010 Removed global variable print_ansi_qualifiers (which made
4011 code non-reentrant), in favor of extra explicit arguments
4012 to internal routines.
4014 Add new helper function print_address_symbolic.
4015 Use find_pc_misc_function instead of find_pc_partial_function
4016 (since we want assembler-level symbols here).
4018 Print unknown function as just "f (...)", not "f (...) (...)".
4019 Use new fputs_demangled explicitly.
4021 Fixed a typing violation (problem: value.h cannot be imported
4022 without renaming many variable in this file).
4023 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
4024 decode_line_1: Moved forward some never-reached code.
4025 Made decode_line_2 skip function prologues correctly.
4027 fputs_filtered should not demangle by default.
4028 Add new fputs_demangled to demangle on demand..
4030 Change value_struct_elt to use value_primitive_field (using recursive
4031 utility function search_struct_field). This allows foo.bar to work
4032 for multiple inheritance (so far only for data fields).
4033 Change check_field in the same way (recursive helper function
4034 to support multiple inheritance).
4035 (Note: there are more of these problems that I haven't fixed.
4036 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
4037 value_of_this: 'this' symbol name is now just "this", note "$this".
4039 Don't print static members.
4040 Avoid printing "members of <type>" if there are none.
4041 Simplified type_print_derivation_info by merging duplicate code.
4042 Remove useless blank lines in type_print_base (ptype command).
4044 Added declaration of new routine value_primitive_field.
4046 Added value_primitive_field which is generalized version of
4047 value_field that can handle multiple inheritance (non-zero offsets etc).
4048 Re-implemented value_field to call value_primitive_field.
4050 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
4052 * infcmd.c -- insert else to avoid 'delete env' coredump when you
4053 delete the whole environment. Karl Berry reported the bug.
4054 * source.c - fix openp to avoid //'s in filenames, which
4055 trigger an Emacs bug causing it to not be able to find files
4056 when running gdb in a window.
4057 * dbxread.c - zap the #if 0 that botches the add-file code.
4058 It seems to work a lot better without all the code commented out.

4075 to remove signle step breakpoint instructions.
4076 * main.c added "-epoch" flag and "int epoch_interface" to main.c

4081 format controls easier
4082 * wait.h added a couple of undef's because we were getting
