1 Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
3 * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
4 sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
5 vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
7 Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
9 * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
10 for these SVR4 systems.
12 * symfile.c (symbol_file_add): When verbose is set, print
13 the names of files from which symbols are being loaded, as
14 when from_tty is true.
16 * solib.c: Completely reorganized (rewritten) to support
17 SVR4 shared libraries in a manner very close to the original
18 SunOS implementation. This support is expected to change and
19 become more general at some future time. The SVR4 version
20 does not yet work for attached processes, for example.
22 * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
23 relocation address to be valid whether or not symbols are
24 being read from a shared library or an executable. Use the
25 relocation address recorded in the psymtab when reading
26 full symbol tables (in read_ofile_symtab). Ensure that the
27 relocated address ranges are recorded in partial symtabs.
29 * elfread.c: Add new function elf_interpreter() to return the
30 string from the ELF ".interp" section. This is the interpreter
31 that the kernel tries to run and feed the executable to.
32 Expand arguments to record_misc_function to include a type arg.
33 Modify elf_symtab_read() to supply the type arg, and to do symbol
34 relocations for symbols read in from shared libraries.
36 * procfs.c: Add new functions proc_base_address() and
37 proc_address_to_fd(), used by shared library support.
39 * tm-svr4.h: Add macros to support SVR4 shared libraries.
40 Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
41 CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
43 Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
45 * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
46 unused START_INFERIOR_HOOK.
48 * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
49 to account for slow loading from floppies.
50 (eb_create_inferior): New fn, from eb_start and
51 nindy_create_inferior.
52 (eb_close): Only use log_file if nonzero.
53 (eb_xfer_memory): If not writing, then read!
54 (eb_read_inferior_memory, eb_write_inferior_memory): Return length.
55 (eb_kill): A new no-op.
56 (eb_mourn_inferior): Remove breakpoints, then generically weep.
58 Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
60 * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
61 miscellaneous comparisons of integer with NULL that elicit
62 compiler warnings about comparison of integer with pointer, when
63 NULL is ((void *) 0) rather than just a bare 0.
65 Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
67 * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
68 while we reset it, in case of problems. Print breakpoint number
71 * buildsym.c (read_struct_type): Avoid sun3 compiler bug with
74 * source.c (find_source_lines): If getting file mod time fails,
77 * target.c (target_xfer_memory): If errno is set, return it,
80 Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
82 * Makefile.in: infodir belongs in datadir.
84 Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
86 * symtab.h (struct fn_field): Add new fields `is_private',
87 `is_protected', `is_stub', making room by reducing the size of
89 (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
90 and `protected_fn_field_bits'.
91 (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
92 (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
93 (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
94 (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
95 * valops.c, valprint.c, symtab.c: All callers updated.
97 * buildsym.c (read_struct_type): Delete the `visibility' field
98 from `struct next_fnfield', and rework code so that visibility
99 info is stored into the fn_field directly. Also, hacked to set
100 TYPE_FN_FIELD_STUB for both static and normal member functions.
102 Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
104 * i386-tdep.c: Fix a problem on i386 systems where buffered code
105 stream access was failing to take into account the minimum size
106 granularity of the code section. For now, the buffering is simply
107 disabled. There is a similar problem in the i386 disassember code
108 that has not yet been fixed (FIXME).
110 * gmalloc.c: Use macros to hide some of the ugly casting required
111 in the previously applied fix for pointers with high bits set.
113 Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
115 * Makefile.in: Roll VERSION to 4.3.1.
117 Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
121 * Makefile.in: Roll VERSION to 4.3
122 * README, TODO, WHATS.NEW, depend: Update.
124 * inflow.c (terminal_inferior): Avoid error msg if attached.
126 * gmalloc.c: Fix bug that causes malloc & free to
127 fail on systems where pointers have the high bit set (0x800efcf0
128 for example). The problem is that the difference between two
129 pointers is a signed integer, so the computation
131 (char *) 0x800efcf0 - (char *) 0
133 yields a negative value. The sign of the result of the modulus
134 operator is machine dependent for negative operands, thus it is
135 possible for it to end up negative. From Fred Fish.
137 Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
139 * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
140 added clean-info. added some standards.text support and made it
141 look like our other Makefiles.
143 * configure.in: mark this directory target dependent. configure
144 now runs entirely in objdir so make existence tests and
145 references against ${srcdir}.
147 Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
149 * dwarfread.c (enum_type, struct_type): Fixes for opaque and
150 anonymous enumerations, structures, and unions. Now passes all
151 the current gdb test suite tests.
153 Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
155 * Makefile.in: idestdir and ddestdir go away. Added copyrights
156 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
157 and mandir now keyed off datadir by default.
159 Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
161 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
162 mid-line, be more careful about possibly advancing to the next line.
164 Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
166 * cplus-dem.c (cplus_demangle): Call `string_need' when
167 null-terminating a partially-computed string.
169 Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
171 * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
172 symbol to the symbol table for each member of the enum.
174 * dwarfread.c (struct_type): Build a correct TYPE_NAME.
176 * dwarfread.c (add_enum_psymbol): New function to extract enum
177 member names and add them to the partial symbol table while
178 building partial symbol tables.
180 Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
182 * symtab.c (check_stub_method): Must allocate two extra argument
183 slots (one for `this', one for arglist terminator).
185 Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
187 * inflow.c (child_terminal_info): Supply missing '"' character.
189 * buildsym.c (define_symbol): Supply missing parenthesis.
191 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
193 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
194 Jay Lepreau <lepreau@cs.utah.edu>.
196 * inflow.c: Remember whether GDB has a terminal. Avoid switching
197 terminals back and forth if we don't have one.
199 * c-exp.y (parse_number): Zero is not an unsigned int constant!
200 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
202 Improve type parsing.
203 * buildsym.c (define_symbol, read_range_type): Add
204 long_kludge_name that passes the names of range types being
205 defined, down to where we must choose between 'int' and 'long'
206 variants. This fails on Sun C anyway since the compiler itself is
207 confused between int and long.
208 (read_array_type, cleanup_undefined_types): Correct the size of
209 array type whose element-type size isn't immediately known.
211 Early preparation to blow away many builtin types, building them
212 on the fly as needed. Don't compare types to builtin types with
213 ==; examine the relevant fields instead.
214 * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
215 * buildsym.c (define_symbol, case 'p'): Avoid ==.
216 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
217 target types are the same.
218 * valprint.c (val_print): I finally understand arrays, remove FIXME.
220 * symmisc.c (printpsyms_command): Reduce redundancy, and put all
221 addresses in GDB itself into parens for easy cleanup and diffing.
223 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
225 * dwarfread (enum_type): Arrange for the order of enumeration
226 members to match the source code order; not the order in the
227 Dwarf information, which is explicitly reverse order.
229 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
231 * main.c (input_from_terminal_p): Check whether GDB has a
233 (initialize_main): Revise doc for `set editing'.
235 Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
237 * dwarfread.c (struct_type): Handle structures and unions which
238 contain DIE's other than just member dies.
240 Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)
242 * symfile.c (reread_symbols): Avoid kludging mtime_set, now that
245 Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
247 * Makefile.in: VERSION 4.2.96.
249 * main.c (initialize_main): Revise command descriptions.
250 * command.c (show_user): `info user' -> `show user'.
251 * symtab.c (_initialize_symtab): Typo in `info types' desc.
253 * coffread.c (coff_symfile_read): Avoid select_source_symtab,
254 since it is not needed and can cause errors when examining ".o"s.
255 (read_coff_symtab, decode_base_type): Use complain, not printf.
256 Print symbol name, not its number.
257 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
258 someday should go in a clipper target config file.
260 * symfile.c (compact_misc_function_vector): Handle empty vector.
261 (complain, clear_complaints, syms_from_objfile): Fix complaint
263 * xcoffexec.c: Change syms_from_objfile caller.
265 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
266 when configured for cross debugging. FIXME, this needs a more
269 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
271 * mips-tdep.c (init_extra_frame_info): Float register
272 'i' has gdb-internal number 'FP0+i', not '32+i'.
273 * mipsread.c (new_symbol): Translate g++ special
274 symbol "$t" to "this".
276 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)
277 Changes due to include file renaming:
279 * xcoffread.c: internalcoff.h ->coff/internal.c,

289 * coffread.c: internalcoff.h ->coff/internal.h
290 * buildsym.c: stab.gnu.h ->aout/stab_gnu.h
291 * depend Updated to take the above into account.

295 * configure.in: Add SVR4 i386 configurations.
297 * config/mh-i386v4, config/mt-i386v4, tm-i386v4.h, xm-i386v4.h:
298 New files for i386/SVR4.
300 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
301 DECR_PC_AFTER_BREAK to be predefined by files including
304 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
305 supply_fpregset(), and fill_fpregset() functions, which are
306 target dependent support functions for the SVR4 /proc register
309 * dwarfread.c (enum_type, struct_type): Expand recognized
310 compiler generated tags to include symbols beginning with '.' as
313 * symtab.c (sources_info): Change simple printf of error message
316 Fri Nov 29 16:04:21 1991 Roland H. Pesch (pesch at cygnus.com)
318 * doc/gdb.texinfo: remove leading comments that survived M4 but
319 described its role in the doc; add one more font to colophon;
320 strengthen disclaimer about unsupported configs.
322 Wed Nov 27 01:23:41 1991 John Gilmore (gnu at cygnus.com)
324 Fix bugs in C++ debugging.
326 * symtab.h: target_type is not used in record types.
327 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
328 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
330 * symtab.c (lookup_member_type): Don't chain them up, just
331 allocate one in symbol_obstack when we need one.
332 (allocate_stub_method): Build stub in symbol_obstack.
333 (check_stub_method): Move here from values.c. Don't deallocate
335 (lookup_method_type): Gone now.
337 * buildsym.c: Handle g++ v1 stabs a little bit better.
338 Change some C++ parsing error()s to complain()ts.
339 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
340 structs have the same representation and work the same as far as
342 * buildsym.c, symtab.c, values.c: Remove all references to
343 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
345 * valops.c: Improve comments and indentation. Only call
346 check_stub_method when the stub flag is on.
347 * valprint.c: Fix or mark minor bugs and unportabilities.
349 * coffread.c (anonymous unions): Allocate a cplus structure.
351 * mipsread.c: Eliminate "template" types. Build new, real
352 types whenever we need them. Allocate cplus structures as needed.
353 Bulletproof the type parsing a bit more. Mark storage leaks.
354 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
355 on top of a partial type.
357 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
359 * inflow.c (terminal_inferior): Check the results of ioctl's, and
360 print a message if any of them fail.
361 (terminal_ours_1): Store result of ioctl's for debugging, but
362 don't print (the terminal isn't ours...).
364 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
367 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
368 conflicts with system header files.
370 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
372 * Roll VERSION to 4.2.95.
374 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
375 first, before defs.h.
376 * config/mh-i386sco: Override compiler to gcc, print warning.
377 * configure.in: Handle i386-none-aout rather than i386-aout-none.
378 * infptrace.c, language.h, utils.c: Lint.
379 * m2-exp.y: #undef MAX and MIN in case system includes set them.
380 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
381 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
382 redefinition warnings.
383 * defs.h: Reorder things so that the xm-file gets first crack
384 at #define's, followed by defs.h and then the tm-file.
385 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
386 Late-model BSD 'make's don't cope with them.
388 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
390 * Makefile.in: Roll new files into various lists.
392 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
394 * dwarfread.c (struct_type): Must initialize the c++ specific
395 portion of union types as well as struct types, since gdb attempts
396 to reference the c++ specific info for both types.
398 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
400 * Makefile.in: Roll VERSION to 4.2.90.
402 * defs.h: Incorporate param.h into defs.h. All users changed.
403 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
404 * param.h, param-no-tm.h: Removed.
405 * Update copyrights in all changed files.
406 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
407 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
408 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
409 xm-merlin.h: Avoid host include files in target descriptions.
410 * getpagesize.h: Removed, libiberty copes now.
411 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
413 * exec.c (exec_files_info): If `verbose' is set, show file offset
416 * main.c: Use getcwd rather than getwd.
417 * standalone.c: Fake getcwd rather than getwd.
418 * xm-*.h: Remove fake values of MAXPATHLEN.
420 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
422 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
424 * Remove gdb/hp-include. Support for HP a.out oddities should be
425 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
427 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
429 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
430 Makefile fragments for various hosts and targets now come from
431 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
434 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
435 * rs6k-opcode.def: Delete.
437 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
439 * dwarfread.c: Recognize obsolete form of AT_element_list
440 attribute still used by at least one AT&T compiler, and possibly
443 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
445 * dwarfread.c (enum_type, struct_type): Ignore names invented by
446 helpful compilers for anonymous structs, unions, and enums.
448 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
449 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
450 can coexist in the same executable without collision.
452 * symtab.h: Add declaration for lookup_template_type() to kill
453 compiler warnings about conversions from int to pointer.
455 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
457 * procfs.c: Move inclusion of defs.h to before param.h, as in
458 all the other source files that include both. This is required
459 to supply some typedefs that are used in files included by param.h.
461 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
462 skipping function prologues, ala the other cpu families (i386,
463 mips, m88k, etc). Add the ability to skip movm and fmovm
464 instructions in the prologues. Still needs support for profile
465 (-p compiled) prologue sequences (FIXME).
467 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
468 m68k prologue skipping function by default.
470 * tm-altos.h, tm-isi.h: Continue to use the old definition of
473 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
475 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
476 * blockframe.c: Remove tdesc-related code. Default
478 * infrun.c: Remove tdesc-related code.
479 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
480 of defaultable things.
481 * tm-m88k.h: New file, common to all Moto 88k target configs.
482 Derived from tm-delta88.h.
483 * tm-delta88.h: Use it.
484 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
485 * xm-delta88.h: Use it.
486 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
488 * coffread.c: Remove tdesc stuff.
489 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
490 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
492 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
494 * source.c (open_source_file): If openp fails, try again
495 using just the base (non-directory) part of the filename.
496 This solves various annoying problems, such as when the
497 source was compiled with an absolute pathname - and the
498 source files have moved. Or if the source was compiled
499 using a relative pathname, it can be more convenient
500 to just specific the source directory to the dir command.
502 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
504 * cplus-dem.c (munge_function_name): Add missing third arg to
505 instance of call to do_type().
507 * dwarfread.c: Changes to match new dwarf.h. Remove
508 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
511 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
513 * symtab.h (struct type): Moved C++-specific fields into new type
514 `struct cplus_struct_type'. Now takes 10% less memory. Many
516 * symtab.c (init_type): Don't set fields belonging to
517 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
518 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
520 (read_struct_type): Ditto. Also, add comments about how we can
521 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
522 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
524 (read_struct_type): Ditto.
525 * dwarfread.c (struct_type): Ditto.
527 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
528 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
529 (lookup_reference_type): Ditto.

538 * mipsread.c (parse_partial_symbols): patch to keep DEC C
539 compiler from making gdb bomb out. Thanks to Ed Santiago!
541 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
543 * symfile.c: Add function compact_misc_function_vector() to
544 remove duplicate misc function vector entries. See comments
545 in source for why this is necessary/desirable.
547 * dwarfread.c: Add misc function type parameter to internal
548 record_misc_function(). Remove calls to init_misc_bunches()
549 and condense_misc_bunches(), these are now done in elfread.c.
551 * elfread.c: Add support for reading bfd canonical symbol tables
552 and generating misc function vector entries for global and
553 absolute symbols. Do calls to init_misc_bunches() and
554 condense_misc_bunches() where they will enclose all calls to
555 record_misc_function(), including those in dwarfread.c.
557 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
559 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm

578 Motorola 88000 port without tears, I mean without tdescs.
580 * m88k-tdep.c: Blow away all tdesc stuff.
581 Provide functions for all the frame-related macros in
582 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
583 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
584 from i960-tdep.c and adapt to the function prologues on the 88k.
585 (read_next_frame_reg): Borrow from mips-tdep.c.
586 FIXME: frame_locals_address should go away.
588 * tm-delta88.h: Dump all the tdesc stuff.
589 Macros for all frame-related stuff call fns of same name.
590 Remove duplicated definitions. FP_REGNUM becomes same as
593 * xm-88k.h: Eliminate lots of library dependencies, now handled
594 in libiberty. Eliminate KDB nonsupport.
596 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.

600 Print locals address (FIXME, remove if same).
601 * blockframe.c: Comment changes, FIXME after.
602 * coffread.c: Even without TDESC, need to zap "@" symbols.
603 Don't register for wierd format names; change the names in BFD.
605 * alloca.c, language.c, tdesc.c: Lint.
606 * tdesc.c, tdesc-lib: FIXME: remove these.
608 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)
610 * Makefile.in: Add tdesc library support. Fixups to lint,

617 Allow setting breakpoints on C++ destructors.
618 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,

620 * symtab.c (decode_line_1): For example (see above), here.
621 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR

624 Fixes to support C++ methods with functional parameters.
625 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
626 types in a function type.
627 * eval.c (parse_and_eval_type), value.h: New function,
628 parse_and_eval_type, is based on old code from check_stub_method.
629 But don't actually evaluate the cast, since that calls
630 value_cast(), whcih may fail. Just extract the type
631 from the parsed expression.
632 * values.c (check_stub_method): While looping through the
633 arguments, adjust depth *after* parameter has been handled.
634 Replace call and setup of parse_and_eval with new function
637 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
639 * utils.c, rem-multi.shar: Remove fixed arg count version of
642 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,

644 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
645 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
646 Change all instances of use of fixed args concat() to variable
647 args concat() now located in libiberty.
649 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
651 * Makefile.in: Add xcoffread.c, xcoffexec.c.
652 * xcoffread.c: New file for handling AIX mangled-coff files.
653 * xconfig/rs6000, tconfig/rs6000: New files.

655 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
656 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
657 * xcoffexec.c: New file for handling AIX shared libraries.
659 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
661 * core.c: Minor rewording of message to user containing name of
662 (and possibly arguments to) the program that generated a core
665 * elfread.c: Remove the register_addr() stub now that it is no
668 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
669 fetch_core_registers() function for core file support.
671 Sat Nov 9 13:37:57 1991 Fred Fish (fnf at cygnus.com)
673 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
674 to do_cleanups() which resulted from a previous change.
676 * elfread.c: Re-enable compilation of register_addr() stub
677 whenever it is not supplied by coredep.c
679 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
681 Add tracking of object files (that contain symbols) to gdb.
682 This includes a "struct objfile" that owns symtabs and psymtabs
683 that were read in from that binary file.
685 * symfile.h: Add struct objfile. Add pointer to the objfile
686 into the struct sym_fns.
687 Replace global `symfile' and `symfile_mtime' with
688 `symfile_objfile'. Add global object_files chain.
690 * symfile.c: Move param.h above symtab.h.
691 (sort_misc_function_vector): Add.
692 (syms_from_objfile): Was syms_from_bfd.
693 (symfile_open): Now returns objfile.
694 (allocate_objfile): New.
695 (free_objfile): New, replacing free_all_.*symtabs.
696 (symfile_init): Takes objfile arg, puts it in sym_fns result.

698 (allocate_symtab): Takes objfile as new parameter, chains them.
699 Handle INIT_EXTRA_SYMTAB_INFO.

702 * dbxread.c: Make more errors into complaints.
703 (push_subfile, pop_subfile): Move to buildsym.c.
704 (dbx_symfile_read, dbx_symfile_init, fill_symbuf, read_dbx_symtab,
705 start_psymtab, psymtab_to_symtab_1, read_ofile_symtab,
706 dbx_psymtab_to_symtab, ): Use bfd ops, don't use file descriptor.
707 Pass objfile. Change callers.
708 (fill_symbuf, SWAP_SYMBOL): Take bfd as arg.
709 (read_dbx_symtab): Just wipe out new symbols, not all, on error.
710 (end_psymtab): Blow away psymtab if empty.

715 * buildsym.c (end_symtab): Pass objfile.
716 (dbx_lookup_type): Handle null typevector.
717 (dbx_alloc_type): Check file number, not sym number, for -1.
718 (find_symbol_in_list): Add for xcoffread.
719 (start_symtab): Default typevector is empty. Keep reusing same
721 (end_symtab): Take objfile argument and pass it to
722 allocate_symtab. Don't make a symtab if no blocks or symbols.
723 Handle empty typevector.
724 (push_context): New function for context stack nesting.
725 (read_type): Mark FIXME where we need to reintroduce type smashing.
727 * buildsym.h (pop_context): Macro, paired with push_context.
728 (subfile_stack): Move here from dbxread.c.
730 * coffread.c (end_symtab, read_coff_symtab): Take and use objfile arg.
731 (read_coff_symtab): Cleanup by freeing objfile, not all symtabs.
733 * mipsread.c (read_mips_symtab, parse_partial_symbols, parse_fdr,
734 new_psymtab, new_symtab): Take and use objfile arg.
736 * dwarfread.c (scan_compilation_units, start_psymtab,
737 process_dies, end_symtab, dwarf_build_psymtabs,
738 read_lexical_block_scope, read_func_scope, read_file_scope): Take
739 and use objfile argument.
740 (psymtab_to_symtab_1, read_ofile_symtab): Don't take or use file
741 descriptor. Use BFD internal functions instead.
742 (end_symtab): Call global allocate_symtab.
744 * elfread.c, target.c: Minor changes to accommodate objfiles.
745 * symtab.h: partial_symbol_table has no symfile_name member now.
746 (fn_fieldlists voffset): avoid non-int bitfield.
747 (struct symtab): Add objfile * and objfile_chain * of symtabs.
748 (struct partial_symtab): Add objfile * and objfile_chain * of
749 psymtabs. Remove symfile_name.
751 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
752 (printsyms_command): Rename from print_symtabs. Add selective
753 listing if 2nd argument given. Print objfile info.
754 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
755 (printobjfiles_command): New; prints objfiles lists, and checks
756 for consistency of symtab, psymtab, and objfile lists.
758 * symfile.h, symfile.c, symtab.h: Lint
760 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
762 * command.c: Include param.h.
763 * defs.h (warning_setup, warning): Declare.
764 * expprint.c (print_subexp, UNOP_MEMVAL case): Lint.
765 * inflow.c (new_tty): Use USE_O_NOCTTY #define.
766 * language.c, printcmd.c (print_scalar_formatted), signame.c,
769 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
771 * Makefile.in: link with libiberty after libreadline, since
772 readline might want something in libiberty.
773 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
774 struct for BCS 88k machines.
775 * xm-m88k.h: don't define USIZE if already defined.
776 * configure.in: Added delta88 target.
778 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
780 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
782 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
783 READ_MIPS_FORMAT, which have been unused since BFD. Still
784 remaining is COFF_NO_LONG_FILE_NAMES.
785 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
786 function calling code moved to m68k-tdep.c.
788 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
790 * coffread.c: Eliminate c_nsyms in favor of c_naux.
791 Complain if no auxents on .bf and .ef FCN symbols, and assume
792 lots of line numbers.
793 (init_linenos, enter_linenos): Use a sentinel at the end of the
794 read-in linenos, to make for a fast, safe loop-end test.
796 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
798 * coffread.c (read_coff_symtab): coffread used to rely on the
799 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
800 function. Two of the formats I'm using (29k and 88k) don't seem to
801 set it. Ths patch to fcn_last_line and (enter_linenos) is an
802 attempt to use the actual size of the linno table in the file to set
803 the number of linenos to process.
805 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
807 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
808 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
809 are created in place, so the mv fails, then the make continues.
811 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
813 Add C++ as a separate language.
814 * defs.h (enum language): Add language_cplus.
815 * dwarfread.c (end_symtab): Support language_cplus.
816 * c-exp.y: Add new struct language_defn cplus_language_defn.
817 Don't set c to be the default language (see main.c).
818 * c-exp.y (yylex): Only look for field of this if
819 language is C++. (First difference from C!)
820 * language.c: Add case branches for C++ (currently, all
821 the same as C). Also, add c++ to "usage" note for "set lang".
822 * valprint.c (typedef_print). Add case branches for C++.
823 * main.c (main): New way to set initial language: Look at
824 file extension of psymtab containing main(). (Same as we
825 do for symtabs, but avoid loading the symtab yet.)
826 * symtab.c: New routine find_main_psymtab(), used by main()
827 to set initial language.
828 * symfile.c (allocate_symtab): Move code for mapping file
829 extensions-> languages to new deduce_language_from_filename().
831 Fix a C++ problem when looking for methods in super-classes.
832 There was confusion between base and derived types.
833 * valops.c (value_fn_field): Change function interface.
834 * values.c: Use new value_fn_field interface.
836 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
838 * infrun.c: Fixed typo in comment.
839 * utils.c: All the v*fprintf emulation is now in libiberty,
840 so we can get rid of some junk.
841 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
842 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
843 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
844 type operands, as used by branch instructions.
845 * gmalloc.c: Fix prototype of memcpy.
846 * elfread.c: Comment out register_addr, since it conflicts
847 with the one in coredep.c.
848 * buildsym.h: Remove extern declarations of two functions
849 that are really static in buildsym.c.
850 * tm-mips.h: Add symbolic names for more registers.
851 * mips-xdep.c (store_inferior_registers): Use new register names.
852 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
853 only used for core files, not ptrace. Therefore,
854 the KERNEL_U_ADDR hack is no longer needed.
855 The mapping to ptrace number is now in in mips-xdep.c.
856 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
857 mapping from the old REGISTER_U_ADDR), and use it
858 in {fetch,store}_inferior_registers.
859 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
860 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
861 Save/restore FP regs correctly (?).
862 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
863 (these had been previously moved to buildsym.c).
864 Hence, define_symbol becomes extern instead of static.
865 * buildsym.c (read_struct_type): Comment out bogus handling
866 of C++ operator methods. Minor hacking of reading of class
867 contexts. Make define_symbol non-static, so dbxread.c can call it.
869 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
871 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
872 filename with error messages.
873 * stack.c (frame_select_command): Rename to select_frame_command
874 to avoid "fr" and "fra" having nonunique completions.
875 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
876 (symfile_init): Print file format name when unable to handle it.
877 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
878 * symmisc.c (free_symtab): Only free linetable if nonzero.
879 * symtab.h: Remove obsolete BLOCKLIST macros.
881 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
883 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
884 that stop_step is 1 at bottom of main loop. I don't know why this
885 needs to be done, but it helps me sleep better at night.
887 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
889 * main.c (initialize_history): Read history after reading all
892 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
894 * buildsym.c: Break out initial malloc sizes.
895 (record_line): Record directly in a subfile. Alloc on demand.
896 (compare_line_numbers): Add from xcoffread.c.
897 (end_symtab): New params say whether to sort pendings and
898 linetable. Patch block stabs if defined. Shrink linetable before
899 allocating the symtab.
900 * buildsym.h: Delete line_vector* and prev_line_number. Add
901 global_stabs and file_stabs for xcoffread.
902 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
903 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
904 * symmisc.c, symtab.c: Cope with null LINETABLEs.
906 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
907 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
908 tm-sparc.h: Accept fromleaf parameter.
909 * c-exp.y (yyerror): Pass error message if given.
910 * configure.in: Add rs6000 host and target.
911 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
912 * symfile.h (entry_point): Add.
914 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
916 * buildsym.c: New file. Breaks out symbol-table-building routines
917 from dbxread.c, so they can be shared with xcoffread.c.
918 * buildsym.h: New file. Declarations for buildsym.c users.
919 * dbxread.c: Remove large chunks into buildsym.c.
920 * Makefile.in: Add buildsym.c and buildsym.h.
922 * symfile.c (syms_from_bfd): New routine.
923 (add_symbol_file): Call it to do the real work.
924 (syms_from_bfd): Initialize entry_point before calling symfile_init.
925 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
926 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
928 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
930 * cplus-dem.c (cplus-demangle): added support for templates, static
931 data, and the new (correct) mangling for destructors.
933 * dwarfread.c: (dwarfwarn): created a varargs version of
934 dwarfwarn, for non __STDC__ compilers.
936 * c-exp.y: (yylex): added match for "template" token.
937 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
938 specification of template types.
940 * symtab.c: (lookup_template_type): new function for finding
941 templates in symbol table.
942 (type_name_no_tag): changed to explicitly check for s/u/e at the
943 beginning of the symbol - if it is a template, none of these will
944 be there (but the name will still contain spaces.)
946 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
948 Various fixes to improve g++ debugging.
949 * symtab.h: Add is_const and is_volatile flags for each method.
950 These are bit fields - take their space from voffset,
951 which shrinks to 30 bits. Since voffset is now a bitfield,
952 make it unsigned for portability. This changes its interpretation
953 slightly: Static methods now have voffset 1 instead of -1,
954 and virtual offsets start at 2, not 1.
955 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
956 since it now returns an entire magled method name, not just
957 the type part. This avoids some duplication.
958 It also allows us to correctly mangle const and volatile
959 methods (using the new is_const and is_volatile bit fields
961 * valprint.c (type_print_base), values.c (check_stub_method):
962 Simplify by using new gdb_mangle_name.
963 * values.c (value_headof): Fix to correctly handle single
964 inheritance (actually two fixes, either of which suffices).
965 * dbxread.c (read_struct_type): Handle const and volatile
967 * dbxread.c (read_struct_type): Yet one more place where
968 we must handle '\\' continuations.
969 * valprint.c (vtbl_ptr_name): Add final '\0'.
971 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
973 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
974 short return values for sparc and 68k. Patch from Paul Eggert.
976 * coffread.c, coredep.c, i386-xdep.c: install patches for
977 SysV/386 3.2 from Mauro DePalma.
979 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
981 * core.c (core_file_info), exec.c (exec_file_info): Print file
982 type. Use printf_filtered.
984 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
986 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
988 * dwarfread.c: Add casts to remove compiler warnings.
990 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
991 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
992 tm-sun3.h: Remove locally duplicated code for calling functions
993 in the inferior. The only differences were in the specific trap
994 vectors used and whether or not an fpu was present. These are
995 now handled by appropriate definitions of BPT_VECTOR and
996 HAVE_68881 respectively. Other minor obvious cleanups.
998 * valops.c: Correct a minor misspelling.
1000 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
1002 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
1005 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
1007 * stack.c (frame_command): Always print. Use new
1008 frame_select_command to select a frame without printing.
1010 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
1012 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
1014 * dwarfread.c: New file for DWARF debugging format support.
1016 * elfread.c: New file for ELF object file format support.
1018 * procfs.c: New file for SVR4 /proc (process file system) support.
1020 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1023 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1025 * xm-m68k.h: New file for host machines with m68k cpu.
1027 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1028 Add elfread.o and dwarfread.o to OBS.
1030 * symfile.h: Add "elf" to list of supported formats in comment.
1032 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
1033 types to gdb, builtin_type_long_double, builtin_type_complex, and
1034 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
1035 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1036 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1037 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1038 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1040 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
1041 call proc_set_exec_trap() to setup child to stop at first instruction.
1043 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
1046 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1047 supply_fpregset(), and fill_fpregset(), which are machine
1048 dependent support routines for SVR4 /proc interface.
1050 * utils.c: Add warning_setup() and warning(). Warning() behaves
1051 the same as error() except that it returns normally rather than
1052 jumping back to command level. Modules that don't want to call
1053 warning() for some reason, but want to produce their own warnings,
1054 can call warning_setup() to ensure compatibility with the way
1055 warning() and error() deal with the terminal.
1057 * symtab.c: Make internal errors produce more useful messages.
1059 * tm-68k.h: Move code that is duplicated in almost every single
1060 m68k based machine's configuration files to this common file.
1061 Duplications in the configuration files still need to be removed
1064 * infrun.c (child_create_inferior): System V versions must call
1065 setpgrp() with no arguments, to comply with prototyping typically
1068 * munch: Add support for SVR4 style nm output.
1070 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
1071 file specific fields from the partial symbol table structure and
1072 replace them with a pointer to private data for each different
1073 flavor of object file reader to initialize appropriately.
1075 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
1077 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
1080 * mipsread.c (fixup_undef_type): New function. If a struct /
1081 union / enum is defined in a header file but nowhere else used,
1082 (by typedefing, pointer referencing or declaration) the mipsread code
1083 builds the complete tree for the structure but leaves its code as
1084 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1085 Guess its type based on the details of the members.
1087 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
1089 * infrun.c (wait_for_inferior): Check return value from
1092 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
1094 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
1095 by my last edit to this routine.
1097 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
1099 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1100 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1101 the values before putting them into the dummy code. (From Peter
1104 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
1106 * configure.in: added ebmon target.
1108 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
1112 * Makefile.in: Roll VERSION to 4.2.
1113 * README, TODO, WHATS.NEW: Update.
1115 * core.c (core_open): Improve error message for bad file.
1116 Pass .reg virtual memory address to fetch_core_registers to help
1117 it find the registers in the core-file header.
1118 * coredep.c (fetch_core_registers): Take new argument, use it,
1119 and pass it to register_addr to locate the block of registers.
1120 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
1122 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
1123 Sequent N_FN_SEQ like everybody else's N_FN.
1125 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
1126 * tm-i386v.h: #endif guck.
1127 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
1128 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
1129 * xconfig/tahoe: Add REGEX, which seems to be missing.
1131 * coredep.c: Add <sys/types.h> for SCOnix.
1132 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
1133 * printcmd.c (print_formatted): Flush output before disassembly.
1135 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1137 * doc/refcard.tex (sec "Working Files"): consistent metavars and
1138 other improvements, due to comments by François Pinard
1139 (pinard@iro.umontreal.ca)
1141 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
1142 configure, and improvenets related to Pinard's refcard comments
1144 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
1146 Changes from Fred Fish:
1147 * tm-68k.h (FPI_REGNUM): Add.
1148 * infrun.c (child_create_inferior): flush stdout and stderr
1150 * configure.in: Handle amigados, amix hosts and targets.
1151 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
1153 From Andreas Schwab:
1154 * values.c (show_convenience): Use printf_filtered.
1155 * main.c (define_command): Check result of lookup_command for
1157 (echo_command): Use printf_filtered, and force output out.
1159 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
1161 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
1162 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
1163 * configure.in, tconfig/decstation, xconfig/decstation: Rename
1164 dec3100 to decstation.
1166 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
1168 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
1169 (nodes Continuing and Stepping; Memory; Targets) clarifications
1172 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
1174 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
1175 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
1177 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
1179 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
1180 generic routines for calling inferior functions.
1182 * blockframe.c (inside_main_scope, inside_entry_scope): New.
1184 * copying.awk: Filter formfeeds out of copying & warrantee.
1185 Make them available as `show copying' and `show warrantee' also.
1186 * main.c (print_gnu_advertisement): Advt `show' commands.
1188 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1190 * mach386-xdep.c: Even when cross-compiling, leave in the
1191 core-file reading code.
1192 * core.c (get_core_registers): Avoid coredump if no .reg section.
1194 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1196 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1197 This avoids coredumps under `set print object on' in value_headof
1198 (called erroneously by value_from_vtable_info) for `p &struct'
1199 or `p *struct'. From Peter Schauer.
1201 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1203 * Makefile.in: Roll version to 4.1.2.
1204 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1205 size from BFD (but, FIXME, we don't yet read external nlists's and
1206 convert them to internal nlists's before handling them -- we still
1207 assume they have the same size and alignment.) Use SET_NAMESTRING
1209 * exec.c (exec_file_command): Move dead coff-encapsulation code
1211 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1213 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1215 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1216 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.

1220 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1221 * mips-xdep.c (store_inferior_registers): Don't try to
1222 write the (pseudo) FP.
1223 * mipsread.c (parse_partial_symbols): Improved algorithm for
1224 setting pst->texthigh.
1226 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1228 * doc/Makefile: make TEXINPUTS include . everywhere
1230 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1232 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1233 vestiges of typevectors, which were for symsegs and are no longer
1234 used. (From a question by Eliot Dresselhaus
1235 <dresselh@RFT30.nas.nasa.gov>).
1237 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1239 * dbxread.c, coffread.c: static-ize functions that were
1240 gratuitiously external. (From Fred Fish.)
1242 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1244 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1245 until it is large enough.
1247 * dbxread.c (read_type): Handle error case slightly better.
1248 Make complaint message not C++-specific.
1250 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1252 * infrun.c (wait_for_inferior): Fix step/next so that you only
1253 stop at the beginning of a new line. This fixes various problems
1254 with for loops, nested if-else's and switch statements.
1256 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1258 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1259 between symtabs and psymtabs become ordinary error()s.
1261 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1262 properly, making "end pc" correct in shared lib psymtabs.
1263 (From Guy Harris <guy@auspex.com>.)
1265 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1267 * dbxread.c: Enable, but soften, const_vol_complaint.
1268 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1269 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1270 should be file-scope, not global.
1271 (read_struct_type): Remove ancient multiple-inheritance warning.
1272 (read_range_type): Check base type, complain & patch if undefined.
1273 * stack.c (frame_info): Demangle the function name in `info stack'.
1274 (From Peter Schauer)
1276 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1278 * eval.c (evaluate_subexp_for_address): Don't use
1279 TYPE_POINTER_TYPE directly (it might be zero if this type has
1280 never had a pointer created before); use lookup_pointer_type.
1281 * symtab.c (lookup_method_type): Arguments were swapped in all
1282 callers, so fix it here. I'm amazed this worked at all!
1284 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1286 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1287 "bss" rather than "data" symbols, but which still conflict.
1290 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1291 * core.c (core_files_info): Shorten output.
1292 * exec.c (exec_files_info): Ditto.
1293 (build_section_table): Ignore zero-length sections.
1294 * language.c, printcmd.c: Lint.
1295 * language.h (get_frame_language): Declare.
1296 * saber.suppress: update.
1297 * stack.c (find_relative_frame): Remove complex code that was
1298 #if 0'd, stick with simple code. Lint.
1299 * saber.suppress: Update a bit.
1300 * symfile.c (add_symbol_file_command): Add "?" to question.
1301 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1302 * value.h: Declare typedef_print.
1304 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1307 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1308 (Reported by Mark Peek <mark@imagen.com>.)
1310 * solib.c (solib_map_sections): Relocate all sections, even
1311 though only the text section's size is tracked. Mark ld_text
1312 for eventual elimination as we generalize to N sections.
1314 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1315 call_dummy if we were stopped by a random signal that is being
1316 passed to the program. This produced wierd results when calling
1317 functions in the inferior and signals (e.g. SIGALRM) were in use.
1319 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1321 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1322 Bugfix from Paul Eggert <eggert@twinsun.com>.
1323 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1324 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1327 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
1329 * Makefile.in: Roll VERSION to 4.1.1.
1330 * source.c (line_info): Peter Schauer fixes a bug I introduced in
1333 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1337 * Makefile.in (VERSION): Set to 4.1.
1338 * language.c (set_language_command): Print useful help message,
1339 and restore the language string after giving help.
1340 * valprint.c (typedef_print): Print typedef in C or M2.
1341 * symtab.c (list_symbols): Use it.
1342 * main.c (main): Avoid any output before (gdb) prompt when -q.
1343 * language.c (set_language_command): Handle errors by restoring
1344 the language string to its current state (fix from A. Beers).
1345 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1346 "how to install" and "how to print the doc" stuff so it drops
1348 * configure.in: Rename rtpc CPU to romp to match config.sub.
1349 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1351 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1353 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1354 autoloading shared libs, copyright etc on GDB startup, clean up $_
1355 and $__ index refs, set/show listsize and related updates to list
1356 cmd. New host/target configs.
1358 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1360 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1361 from main Makefile.in version definition
1362 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1364 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1366 * doc/gdb.texinfo: merge new language-switching and lang-specific
1369 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1371 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1372 compilers (which may lack stddef.h).
1374 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1376 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1377 N_WARNING are the same except for the N_EXT bit, so just use their
1378 values alone, rather than OR-ing them with N_EXT.
1380 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1382 * mipsread.c (parse_lines): Deal with negative extended line
1385 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1386 global symbol conflicts.
1388 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1390 * .gdbinit: Move 'set complaints' to top, so it runs even in
1391 case we aren't debugging GDB.
1392 * language.c (_initialize_language): Fix type check and range
1393 check documentation strings.
1394 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1395 language.c can use it. (Though language.c should really not be
1396 handling warnings/errors the way it does, FIXME.)
1397 * symtab.c (lookup_primitive_type): const lint.
1399 Bugfix from Peter Schauer:
1400 * source.c (lines_to_list): Make signed, to avoid comparison
1401 going unsigned and complaining that -3 is too high for 21 lines.
1402 * stack.c (lines_to_list): Ditto.
1404 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1406 * Makefile.in (HFILES): Add minimon.h.
1407 (VERSION): Roll version number to 4.0.95.
1408 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1409 New rules for building distributions. Normal distribution
1410 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1411 one level up from here; it calls make-proto-gdb.dir to build a
1412 directory `proto-gdb' which is an image of the release. The old
1413 `gdb.tar.Z' rule still works too.
1414 * config.sub, configure: Roll in latest from ..
1416 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1418 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1419 new-target, and new-config chapters; fix minor typos; come closer
1420 to usual GNU markup conventions for @file @samp @code @var.
1422 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1424 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1425 * mipsread.c (parse_partial_symbols): Enter the name of all
1426 structs/unions... into the psymtab so we can access them if the
1427 symtab is not read in.
1428 * mips-tdep.c: Remove some unneeded #includes.
1429 * xconfig/dec3100: Add HAVE_STRSTR.
1431 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1433 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1434 * c-exp.y, m2-exp.y: Lint.
1435 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1436 * valprint.c (val_print_fields): Check for stub type.
1437 * mipsread.c (_initialize_mipsread): Avoid using
1438 builtin_type_void at initialize time.
1439 (mipscoff_symfile_read): use it now.
1441 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1443 Merge multiple-language support, and partial Modula-2 support,
1444 from Andrew Beers <beers@cs.buffalo.edu>.
1446 * i387-tdep.c: New file, consolidates most 80387 support,
1447 and eliminates host dependency on double<->extended conversions.
1448 * i386-xdep.c, symm-xdep.c: Remove most 387 support.
1449 * xconfig/i386{sco,v,v-g,v32,v32-g}: Now need i387-tdep.o.
1451 * symfile.c (allocate_symtab): New fn, consolidates the work
1452 of allocating and initializing a new struct symtab. Set the
1453 language of the symtab based on its filename extension.
1454 * symfile.h: Declare it.
1455 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1456 * dbxread.c (end_symtab): Use it.
1458 * mipsread.c (parse_symbol, case stParam and stProc): Add #if 0'd

1540 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1542 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1543 entries are enclosed herein. Not all of these changes
1544 have been merged into the master GDB sources -- check the
1545 ChangeLog above here for the merge log.
1547 Mon Jun 3 17:05:45 EDT 1991
1549 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1550 operators were added, C specific operators and tokens
1551 removed. yylex() revamped to some extent. Still things
1552 missing from the grammar, such as sets.
1553 Tested for two weeks in GDB v3.5.
1555 Tue Jun 11 17:23:48 EDT 1991
1557 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1558 so they are built-in. Sort of a hack.
1560 Fri Jun 14 12:53:51 EDT 1991
1562 m2-exp.y Added range checking for numeric constants. Any numeric
1563 constant is assumed to be of builtin type INTEGER unless:
1564 (1) it is octal or hexadecimal, in which case it is a
1565 CARDINAL; (2) it is too big to fit into an INTEGER, in
1566 which case it is a CARDINAL.
1567 eval.c Added simple range checking for +, -, and * on integers.
1568 Doesn't work very well for *, since 6 * 1,000,000,000 =
1569 1,705,032,704, which fails the simple test of result >=
1570 first_operand, no matter in what order the operands are.
1572 Tue Jun 18 14:11:30 EDT 1991
1574 Broke the parser into parts, one containing the C grammar and the other
1575 containing code to be shared by all of the grammars.
1577 The following files no longer exist:
1582 The following files were added:
1584 c-exp.y (The C grammar)
1585 m2-exp.y (The Modula-2 grammar)
1586 parser-code.c (Code that is shared by the above grammar)
1590 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1591 now necessary to use the Bison compiler compiler, since it
1592 will generate function/variable prefixes other than yy.
1594 Tue Jun 18 16:47:49 EDT 1991
1596 symtab.[ch] Added the external variable working_lang, than holds the
1597 value of the current working language.
1598 Added the ennumerated type language_mode, with the values
1599 language_auto and language_manual, the former meaning that
1600 GDB sets working_lang as needed, and the latter meaning
1601 that the value of working_lang is totally under user
1603 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1604 REAL, BOOLEAN and CHAR. Also added the type codes
1605 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1606 utils.c Added set_language_command and show_language_command to
1607 implement the GDB support commands "set language" and
1609 expression.h A number of identifiers were added to the type exp_opcode
1610 to facilitate Modula-2 builtin functions, integer
1611 division, and array indexing.
1613 Wed Jun 19 13:25:58 EDT 1991
1615 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1616 if the language specified by working_lang requires the use
1617 of strict typing of expressions. Eventually, even this
1618 will be able to be changed by the user.
1619 Added the macro RANGE_CHECK, which evaluates to non-zero
1620 if the language specified by working_lang requires the
1621 checking of a value against the domain of its type.
1622 Eventually, even this will be able to be changed by the
1624 language.[ch] Predicates involving types (simple_type, ordered_type,
1625 same_type, integral_type, numeric_type, character_type,
1626 boolean_type, float_type) are added. These predicates are
1627 based on the current value of working_lang, and are handy
1630 Wed Jun 19 15:39:34 EDT 1991
1632 eval.c Added the function type_array_rank which computes the rank
1634 valarith.c Added the funtion value_bool, which when given a integer
1635 value.h value (ie. struct value *) as an argument, it returns a
1636 boolean value (ie. struct value *) true if that integer
1637 is non-zero, and a boolean value false otherwise.
1638 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1639 will print out properly.
1641 Wed Jun 19 16:36:34 EDT 1991
1643 valops.c Added the function value_capitalize, which returns it
1644 value.h argument capitalized if its argument is a lowercase
1645 letter, or the argument unchanged if its argument is not a
1647 valarith.c Added the function range_check_p, which returns non-zero
1648 value.h if its value argument is between the integral bounds upper
1650 Added the function range_check_enum_p, which makes sure
1651 that its value argument is a valid member of the domain of
1653 Added the function range_check_range_p, which makes sure
1654 its value argument lies between the upper and lower bounds
1655 of its type argument, which must be a ranged type.
1656 Added the function check_array_index, which range and type
1657 checks an index of an array.
1658 Added the function value_multi_subscript, which computes
1659 array[idx1,idx2...idxN], given a value array and an array
1660 of values representing indicies.
1661 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1662 unpack_long to work with TYPE_CODE_BOOL and
1665 Wed Jun 19 18:04:08 EDT 1991
1667 symtab.c Stored pervasive types in a structure and make
1668 lookup_pervasive_type() a lookup function that was based
1669 on working_lang. If lookup_pervasive_type() returned
1670 non-zero, then that value was returned (a fix, since
1671 before it simply wouldn't return the pervasive type.)
1672 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1673 non-zero if the language specified by working_lang means
1674 "conversion" when it says "cast".
1675 valops.c Added the function value_real_cast(), which performs a
1676 value.h *cast*, not a *conversion*, which is what value_cast()
1677 does when it can. In particular,
1678 value_cast(<float_type>,4) = 4.0, while
1679 value_real_cast(<float_type>,4) = some mess.
1680 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1681 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1682 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1683 and MIN on integral types. *NOTE*: These are currently
1684 hardcoded to work only if there are 8 bits per storage
1686 eval.c Made logical functions call value_bool to return a
1687 properly typed boolean value, based on working_lang.
1689 Thu Jun 20 11:55:27 EDT 1991
1691 valprint.c Types now print out in a Modula-2 fashion. This works for
1692 the cases when the type is printed out step-by-step, that
1693 is, it doesn't work when the name of a structured type
1694 (which includes the keyword "struct", etc.) is simply
1696 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1697 since type specifications in C and Modula-2 are very
1698 different. The C printing of a type is very recursive,
1699 whereas in Modula-2 it is generally very simple. C has
1700 type prefixes and suffixes, which have no real analogue in
1701 Modula-2. Maybe type_print() should call a language
1702 specific type printer. This is also advantageous if we
1703 compile GDB to exclude some of the languages. We'll just
1704 leave those functions out.
1706 Thu Jun 20 16:57:10 EDT 1991
1708 dbxread.c When reading the complete symbol table in (via
1709 psymtab_to_symtab()), the number and types of function
1710 arguments are added to a function type. define_symbol()
1711 calls add_param_to_type() to accomplish this.
1712 Assumption: when we come across a function definition
1713 (N_FUN symbol with an 'f' or 'F' in the name), its
1714 arguments will appear before another function definition.
1715 When a function is found, a pointer to its type is placed
1716 in the global in_function_type. Changes that
1717 add_param_to_type() makes are to this global.
1718 valprint.c The type of a function now includes (for Modula-2) the
1719 types of its parameters.
1720 eval.c Type checking and a check for the proper number of
1721 arguments is now done for function calls. Not sure of the
1722 impact this has on C++ member function yet.
1724 Thu Jun 20 19:58:48 EDT 1991
1726 valprint.c Rewrote the type printer. Broke it into two language
1727 specific parts, adding the functions type_print_m2() and
1729 An unfortunate consequence is this: if you debugging a C
1730 program in Modula-2 mode (why?), info types does not work
1731 well with regular expressions, since the types are printed
1732 out in Modula-2 terminology, but stored in C terminology.
1733 language.[ch] Added the functions new_type_last(), type_keyword(), and
1734 type_sep() to aid in the printing of typedefs.
1735 symtab.c Made the printing of typedefs as language independent as
1736 possible through calls to new_type_last(), type_keyword(),
1739 Fri Jun 21 11:50:26 EDT 1991
1741 dbxread.c Check all incoming ennumerated types. If it looks like
1742 Modula-2's BOOLEAN type, then change the type_code of the
1743 type to TYPE_CODE_BOOL so we can process it as a boolean
1745 valprint.c Replaced some of the 0x%x with calls to sprintf and
1746 hexformat() in val_print().
1747 language.[ch] Added the function hex_to_string(), which converts its
1748 integral argument to a hexadecimal number (format is
1749 language based) and returns the result as a string.
1751 Mon Jun 24 12:25:07 EDT 1991
1753 valprint.c Some functions call type_print_1() directly, instead of
1754 value.h using type_print(), so they can specify where (column) to
1755 print things. Since type_print() takes care of language
1756 dependence, that needs to be called first. Added a
1757 parameter depth to type_print() (so it is now like
1758 type_print_1). Changed type_print to type_print_at, and
1759 made type_print a macro that passes a depth argument of
1761 symmisc.c Changed all calls to type_print_1 to calls to
1763 Makefile.dist Made it possible to build GDB for a specific set of
1764 depend languages. Do this by passing a definition for the macro
1765 LANGS to make. LANGS should be a string containing a
1766 space-separated list of language names (ie. LANGS="c m2").
1767 The default is to build all languages. Note that grammar
1768 files must follow the naming convention of <lang>-exp.y.
1769 gdb.lang This holds the current value of the LANGS macro. It is
1770 examined every time make is called, and is updated if
1772 eval.c Added #ifdef _LANG_<lang> to these files.
1773 expread.c Still need to add them to dbxread.c and coffread.c.
1781 Mon Jun 24 16:33:11 EDT 1991
1783 language.[ch] Added the functions hexformat_pre() and
1784 hex_to_string_pre(), which take a prefix argument to
1785 include in the format string. Thus, hexformat_pre("08") will
1786 return "0x08x" (if the working language is language_c).
1787 Made hexformat() and hex_to_string() calls to the above
1788 with "" as the prefix argument.
1790 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1791 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
1792 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
1793 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
1794 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
1795 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
1796 valprint.c, vax-pinsn.c
1798 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1799 calls to hexformat() and hex_to_string(). Format strings without
1800 the leading "0x" were ignored.
1802 depend Updated to take the above into account.
1805 Tue Jun 25 15:27:18 EDT 1991
1807 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1808 and type_check_t to keep track of the current state of
1809 range and type checking.
1810 main.c Added the variables range_mode, range_check, type_mode,
1811 and type_check to record the current state of range and
1812 type checking. Added initialization code to main().
1813 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1814 the above variables.
1817 Tue Jun 25 17:57:08 EDT 1991
1819 dbxread.c process_one_symbol() updates the variable (enum language)
1820 source_lang based on the extension of the filename
1821 contained in the N_SO sybmol that started this symtab.
1822 When end_symtab() is called, the value of source_lang is
1823 put into the language field.
1824 stack.c select_frame() sets working_lang (and possibly type_check
1825 and range_check) to the language field of the symtab
1826 associated with the frame that is selected if working_mode
1827 is language_auto. If working_mode is language_manual, a
1828 warning is printed and working_lang is not set.
1829 language.c Added the function set_type_range(), which sets the value of
1830 type_check and range_check (if their modes call for
1831 automatic setting) based on the current value of
1832 working_lang. A non-zero argument will cause the current
1833 settings to be output.
1836 Wed Jun 26 14:51:40 EDT 1991
1838 eval.c Added range checks on assignment.
1839 m2-exp.y Added the grammar for sets to the language. Currently,
1840 these do not do anything except print an error message.
1842 Wed Jun 26 17:01:04 EDT 1991
1844 m2-exp.y Added the ability for parse_number() to parse negative
1845 numbers. A global flag is set upon encountering a unary
1846 minus. This was done to make, for example, 1 parse as a
1847 CARDINAL, and not as an integer, per Wirth's examples in
1848 Programming in Modula-2 ed.4.
1849 valprint.c Added support for "set radix 2" by then setting
1850 output_format to 't'.
1851 eval.c Implemented range checking on subrange types. Added calls
1852 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
1853 Implemented MIN and MAX for ennumerated types. The
1854 minimum value of an ennumerated type is defined by Wirth
1855 as the first identifier, and the maximum as the last.
1856 m2-exp.y Made octal numbers ending with "B" be characters and those
1857 ending with "C" be numbers, per Wirth's book. (p. 34)
1859 Thu Jun 27 14:11:52 EDT 1991
1861 stack.c select_frame() now only sets working_lang, it does not
1862 notify the user. If working_mode is language_manual, then
1863 a warning is issued once.
1864 main.c At the end of each call to execute_command(), working_lang
1865 is checked against the local static (enum language)
1866 current. If they differ and working_mode is
1867 language_auto, the new settings of language, type and
1868 range checking are printed out.
1869 stack.c Modified frame_info() to include the language of the
1870 current frame in the output of "info frame".
1871 language.[ch] Added the function language_str() which returns the name
1872 of the current language.
1874 Fri Jun 28 15:33:14 EDT 1991
1876 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
1877 the language. INCL and DECL currently cause an error,
1878 since sets are not implemented yet. INC and DEC are
1879 implemented as PREINCREMENT/PREDECREMENT with one
1880 argument, and as ASSIGN_MODIFY with two arguments.
1881 eval.c Added type checking to the above cases.
1882 value.h Added not_lval_constant to the lval_type ennumerated type.
1883 not_lval_constant means that the value is a constant
1884 value; that is 3 or 'a' or TRUE, not as in a constant
1885 identifier. This is used to help coerce numbers such as 3
1886 to either signed or unsigned numbers.
1887 valops.c Added the function value_coerce_constants() which coerces
1888 constant integers as following: if one is a constant and
1889 the other is not, the constant's type is set to the type
1890 of the other argument. If both are constants and one is
1891 signed, the other is converted to a signed constant.
1893 Sat Jun 29 17:26:29 EDT 1991
1895 valarith.c Added a better range checker. It now checks range
1896 (successfully) on integral operations [+-] (signed and
1897 unsigned) for any C sized type. Still does not work well
1898 for multiplication.)
1899 int_in_size() returns an integer that is coerced to fit into
1900 specified number of bytes.
1902 Mon Jul 1 13:04:14 EDT 1991
1904 language.[ch] Added the function binop_result_type(), which returns the
1905 builtin (struct type *) type that would be the result of a
1906 binop on the two values V1 and V2.
1908 Wed Jul 3 19:22:53 EDT 1991
1910 source.c Extended source_info() to include the source language in
1911 the output from "info source".
1913 Fri Jul 5 13:48:52 EDT 1991
1915 utils.c Moved the support functions for the GDB set/show commands
1916 dealing with language into language.c.
1917 language.c Added the function language_info(), which displays info
1918 about the current working language, type and range check
1919 settings. Called via the GDB command "info language".
1920 Added an initialization routine _initialize_language(),
1921 that sets defaults for the language, type and range
1922 variables and sets up the new GDB commands.
1923 main.c Language setup moved to language.c.
1926 Mon Jul 8 10:10:22 EDT 1991
1928 valarith.c Debugged the range checker for arithmetic. Still does not
1929 work for multiplication very well.
1931 Mon Jul 8 12:40:37 EDT 1991
1933 language.[ch] Added the function value_true() which returns non-zero if
1934 its argument represents a boolean true value.
1935 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
1936 check the truth of an expression.
1938 Thu Jul 11 12:51:34 EDT 1991
1940 language.[ch] Added the predicate structured_type(), which returns
1941 non-zero if the argument is a structured type.
1942 Added the predicate pointer_type(), which returns non-zero
1943 if the argument is a pointer type.
1944 eval.c Added the ability to do addition and substraction on
1945 pointers and integers. This case simply bypasses the
1948 Thu Jul 11 14:41:42 EDT 1991
1951 Added the symbol N_DEFD (0x4a) which is a definition
1952 module dependency that is used by the GNU Modula-2
1953 compiler and the linker. It is not important to GDB,
1954 except that [dbx|coff|mips]read.c should ignore these
1957 Fri Jul 12 16:07:00 EDT 1991
1959 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
1960 0 in val_print(). Also added statements to the else part
1961 to coerce type (argument to val_print) to a pointer type
1962 if it is an "array of unspecified length".
1963 valops.c Added the function value_m2_string(), which returns a
1964 (value) value which is a constant string, whose type is
1965 (ARRAY [0..n] OF CHAR). The length field of the type
1966 structure is set to zero, so it will be interpreted as an
1967 "array of unspecified length".
1968 stack.c Moved the language/frame mismatch check to
1969 main.c:execute_command().
1970 main.c The working language is recorded each time
1971 execute_command() is executed. If working lang has
1972 changed during its execution, then the new
1973 language/type/range info is printed out for the user. If
1974 the working language does not match the language of the
1975 frame, a warning is issued.
1977 Sat Jul 13 16:16:39 EDT 1991
1979 eval.c Moved all the type-checking stuff for operators to
1980 language.[ch] language.c. This is so we can keep language-specific
1981 stuff (like for what type operators are defined) in
1983 language.[ch] Added the function binop_type_check(), which checks to see
1984 if its two (value) arguments are type-compatible with its
1985 opcode argument. The opcode should represent an operation
1986 involving an operator. Also added the macro function
1987 unop_type_check, which calls binop_type_check with a
1988 NULL second argument.
1989 expprint.c Added Modula-2 operators to the op_print_tab, so info
1990 expression.h break works correctly. Also added "op_string", which
1991 returns the string corresponding to the (enum exp_opcode)
1992 opcode that is its argument.
1995 Sat Jul 13 18:26:18 EDT 1991
1997 coffread.c Added code to record the type of function arguments with
1998 each paricular function. Code is very similar to that
2000 dbxread.c Moved add_param_to_type() to symtab.c
2001 symtab.[ch] Added function add_param_to_type() from dbxread.c
2003 *** NOTE: The above additions have not been tested.
2005 Mon Jul 15 12:50:47 EDT 1991
2007 langauge.[ch] Added the functions type_error and range_error, which work
2008 like error() except if the type/range mode is set to
2009 *_mode_warn, then they do not do a return_to_top_level(),
2010 but merely print a warning.
2011 Also changed [set|show]_[type|range]_command() to support
2012 the new "warn" feature.
2014 Thu Jul 18 17:50:54 EDT 1991
2016 mipsread.c Added code to record the type of function arguments with
2017 each particular function. Code is very similar to that
2020 *** NOTE: The above additions have not been tested.
2022 Fri Jul 19 11:19:10 EDT 1991
2024 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2025 UMIN_OF_SIZE, which when given a size of a numeric type,
2026 return the maximum and minimum value it can hold. UMAX...
2027 and UMIN... return the result for unsigned types.
2028 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2029 struct types. They call above macros.
2030 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2031 avoid a name conlict with the above.
2032 c-exp.y Added range checking on numeric constants in
2033 parse_number() for completeness.
2034 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
2035 return 0 if working_lang is not language_c.
2037 Thu Aug 8 14:17:22 EDT 1991
2041 breakpoint.c Documentation strings of some commands changed to
2042 eliminate the references to the C language where
2045 Tue Aug 13 15:48:03 EDT 1991
2047 m2-exp.y Added qualified identifiers to the grammar. The semantics
2048 are slightly different from those of the GDB operator ::
2050 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
2051 type_exp, where type_exp is any valid type expression.
2053 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
2054 printcmd.c Modified ptype_command() so it actually parses the input
2055 (necessary for type expressions with scope qualifiers).
2056 Added the function ptype_eval() which expects an
2057 expression composed of one OP_TYPE element.
2058 *.[ch] Replaced all occurences of parse_c_expression with
2060 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
2062 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
2064 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
2066 Small fixes from Peter Schauer:
2068 * infrun.c (child_attach): Lint.
2069 * solib.c (find_solib): Handle shared libs version 2.
2071 Small fixes from David Wood:
2073 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
2077 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
2078 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2080 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
2081 chars_per_line is at maximum (user typed `set width 0'). Fix
2082 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2084 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
2086 * coredep.c: include ptrace.h where necessary.
2087 * mipsread.c(parse_lines): fix unsigned char problem that was
2088 messing up line numbers on SGI's and possibly other MIPS based
2090 * infrun.c (child_create_inferior): use better test to check
2091 return val from setpgrp().
2092 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
2093 for sgi/irix support.
2095 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
2097 * mipsread.c (parse_symbol): Put non-static procedures
2098 in the global block.
2100 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2102 Patch together `text_start' and `text_end' for 29K port.
2104 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2105 variables and set them based on the exec file.
2106 * am29k-tdep.c: declare text_start.
2107 * valops.c (call_function_by_hand): declare text_end.
2109 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2110 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2111 because machines that do this will also have to know to
2112 set NEED_TEXT_START_END. Besides, it was a redundant way to
2114 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2115 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2116 NEED_TEXT_START_END.
2118 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2120 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2122 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2123 Pass MUNCH_DEFINE to munch whenever we run it.
2124 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2125 format string; use 0x%x instead.
2126 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2127 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
2128 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
2129 * inflow.c: Handle `short' process group IDs.
2130 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
2131 and check for ptrace errors.
2132 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
2133 (coff_symfile_init): Initialize text_bfd_scnum.
2134 (read_coff_symtab): Use it to find the text [and absolute?] sections.
2135 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
2136 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2137 Merge target arm case with other "easy" cases. Add target
2138 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2139 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2141 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2142 * munch: Cope with RT/PC putting fns in data segment.
2143 Restore ability to override `nm' by specifying MUNCH_NM.
2144 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2145 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2146 and remote-adapt. Remove encapsulated coff #define's (the
2147 support should go in BFD, and gdb shouldn't know or care).
2148 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2149 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2150 * tm-29k.h: Update BADMAG (though it should go away).
2151 Allow the register definitions to be overridden in another
2152 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2153 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2154 DUMMY_SAVE_GR96, for handling kernel calling conventions
2155 that use GR64+ rather than GR96+.
2156 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2157 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2158 overrides various things.
2160 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2161 child_attach does, making a clean stop in the newly attached
2163 * remote-eb.c: Lint.
2165 * coffread.c: Make coffread independent of any particular
2166 variant of COFF. Avoid #include-ing any particular one except
2167 internalcoff.h. BFD now passes key values for symbol reading
2168 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2169 and the symbol masks and shifts); use them.
2170 Remove obsolete end_of_text_addr.
2172 * exec.c: Remove unused include files.
2174 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2176 * Makefile.in (documentation targets): Pass $(M4).
2177 Bugfix from eggert@twinsun.com (Paul Eggert).
2179 * stack.c (down_silently_command): Check for stack existence.
2181 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2183 * Makefile.in (VERSION): Update to 4.0.3.
2185 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2187 * core.c (core_file_command): Print frame at coredump with
2188 its level number, by calling print_stack_frame.
2189 * frame.h: Add selected_frame_level, print_stack_frame.
2190 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2191 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2192 Change print_sel_frame and print_selected_frame callers to
2195 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2196 * symfile.c (free_named_symtabs): Ditto.
2197 * main.c (main): wrap_here needs an arg.
2198 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2199 (solib_add): Avoid noise.
2200 (solib_create_inferior_hook): Lint.
2201 (sharedlibrary_command): Move dont_repeat to here.
2202 * utils.c (error): Call wrap_here to force buffered output.
2204 Small patches from Peter Schauer:
2206 * coffread.c (start_symtab): Free any existing line_vector before
2208 (read_coff_symtab): Ditto for type_vector.
2210 * source.c (lines_to_list): New variable, replacing function.
2211 (all uses): Use as variable.
2212 (_initialize_source): Add 'set listsize' and 'show listsize'.
2213 * utils.c (lines_to_list): Remove function.
2214 * stack.c (print_frame_info): Use as variable.
2215 * defs.h (lines_to_list): Remove declaration.
2217 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2219 * breakpoint.c (insert_breakpoints): Restore warning about
2220 the program might be running in another process, but only for
2221 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2222 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2224 * utils.c (error): if error_pre_print is set, print the string
2226 * main.c (main, print_gnu_advertisement, print_gdb_version):
2227 Reformat legalese so it always prints, but acts as an "I'm here"
2228 message while symbols are being read. If any errors occur,
2229 print a few newlines to set off the message and start it at the
2230 left margin. Remove mention of "help" command, and don't yak
2231 about symbol reading.
2232 (catch_errors): Error string is now printed first in case of
2234 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2235 suggest the "help" command.
2237 * Makefile.in (VERSION): Set to 4.0.2.
2239 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2241 * .gdbinit: Remove useless "rr" command. Set complaints
2242 to 1 for people debugging gdb.
2244 * breakpoint.c, remote-vx.c: Reword strings printed by
2245 catch_errors callers.
2247 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2249 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2250 (Fix from kenc@viewlogic.com.)
2252 Fix some infrastructure to be able to cope with host and target
2253 machines with different sized basic types (ints, ptrs, etc).
2254 (Idea from pierre@la.tce.com (Pierre Willard).)
2256 * values.c (value_from_longest): Rename from value_from_long.
2257 Handle pointer types as well as integers, so that targets with
2258 different pointer sizes from the host can be accomodated.
2259 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2260 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2261 uses of value_from_long to value_from_longest.
2262 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2263 the correct pointer type to value_from_long{est}.
2265 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2267 * remote-vx.c: Remove obsolete code for calling functions via
2268 vxworks kludge interface (it referenced value_from_long).
2270 * valops.c (value_string): Find malloc with lookup_misc_func, not
2273 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2275 Make writing to files work properly. (Fixes to BFD are also needed.)
2277 * core.c (core_open): Open file ourselves, read or r/w, depending on
2278 write_files. Use bfd_fdopenr.
2279 * gdbcore.h (write_files): New variable.
2280 * exec.c (write_files): Define variable, add set&show for it.
2281 (exec_file_command): Use write_files to open for read or r/write.
2283 Make shared library reading happen automatically. These changes
2284 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2286 * inferior.h (stop_soon_quietly): Add to exported variables.
2287 * infrun.c (child_create_inferior): call solib hook, if defined.
2288 (child_attach): call solib hook, if defined.
2289 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2290 (find_solib): Use lookup_misc_func rather than hand-rolled.
2291 (symbol_add_stub): New stub for catch_errors.
2292 (solib_add): Avoid output if !from_tty. Catch errors rather
2293 than just calling symbol_file_add and bombing.
2294 (solib_create_inferior_hook): Interface with the target process
2295 to let it read and alloc shared libs, then figure out what it did.
2297 * core.c (validate_files): Fix typo, soften warning.
2298 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2300 * utils.c (fputs_demangled): Avoid duplicate printing if
2301 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2303 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2304 (Fix from pierre@la.tce.com (Pierre Willard).)
2306 * main.c (catch_errors): Change argument to a char * from an int,
2307 since a char * can point to a struct full of glop, but an int
2308 is not guaranteed to be able to hold a pointer.
2309 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2310 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2311 * core.c (core_open, solib_add_stub): Adapt.
2312 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2314 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2316 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2317 by adding .NOEXPORT target.
2319 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2323 * Makefile.in (VERSION): Roll to 4.0.
2324 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2326 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2328 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2331 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2334 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2336 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2337 reflect above name change
2339 * WHATS.NEW: correct pointer to refcard.
2341 * doc/gdb.texinfo: update New Features, Installing
2343 * doc/gdbint.texinfo: add short description of configure +template
2345 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2347 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2349 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2351 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2352 tar file, add dependencies for referenced doc files.
2354 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2356 * coffread.c, symfile.c, stack.c: saberized.
2358 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2360 * doc/refcard.tex: permuted Essential Commands sec
2362 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2364 set/show symbol-reloading
2365 default set complaints 0
2367 RET-repeat disabled after prompted long displays
2368 processID (attach) interpretation of 2nd GDB cmdline arg
2370 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2372 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2373 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2374 breakpoint.c, main.c: lint.
2376 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2378 Install new configuration scheme for GDB and friends.
2380 * config.sub: Translate ordinary names to three-part names.
2381 * configure: Use three-part names internally.
2382 * configure.in: Translate three-part names to filenames.
2384 * README, WHATS.NEW: Update for gdb-4.0.
2385 * Makefile.in: Roll VERSION to 3.99.
2387 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2389 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2390 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2391 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2392 to single structures rather than arrays; when passing
2393 their address, use &. This avoids trouble with bdead compilers.
2394 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2395 instead. This avoids portability headaches.
2396 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2398 * source.c (open_source_file): Avoid ANSI const bdeath by
2399 skipping declaration and then casting result value.
2400 * tm-hp300bsd.h: Clarify comment.
2401 * utils.c (strstr): Result is const char *; ANSI bdeath.
2402 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2403 since system include file defines it differently from "defs.h",
2404 though the two are equivalent for our purposes.
2405 * tconfig/hp300bsd: Add m68k-tdep.o.
2407 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2409 * tconfig/sun*4: Remove warnings about system assembler.
2411 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2413 * mcheck.c: Avoid warning about undeclared abort fn.
2414 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2415 it causes recursive calls to error() when used in cleanups.
2416 To do so requires that we make it a function, so we do.
2417 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2418 * utils.c (do_cleanups): Remove the current cleanup from the
2419 chain *before* calling it, in case error() is called from it.
2420 The result won't be pretty, but won't be an infinite loop either.
2422 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2424 * dbxread.c (read_struct_type): Grok anon structs for C++.
2425 (vb_name, vptr_name): Null terminate these strings.
2427 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2429 Minor bug fixes from BSD Net2 gdb:
2431 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2432 returns 0, there is no previous frame.
2433 * breakpoint.c (commands_command): If !from_tty, don't call
2434 input_from_terminal_p().
2435 * dbxread.c (record_misc_function): Speed up slightly.
2436 (compare_psymbols): Ditto.
2437 * infcmd.c (do_registers_info): Take a second argument to
2438 determine whether to print float registers. "info registers"
2439 does not do so anymore. "info all-registers" does, now.
2440 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2442 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2443 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2447 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2448 executing_breakpoint_commands if we are interrupted by error.
2449 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2450 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2451 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2452 catch_errors() so we can setup the frame regardless of whether
2453 the shared libs work.
2454 * ieee-float.c (double_to_ieee_extended): Get exponent from
2455 right place in little-endian systems. From John Carey.
2457 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2459 * main.c: Remove unused terminating_signals and catch_termination().
2460 (long_options): Terminate with a zero element.
2461 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2462 (gdb_readline): Make call-compatible with readline.
2463 (init_signals): Improve comments re vfork vs. signal.
2465 * utils.c (prompt_for_continue): Use new gdb_readline().
2466 If we prompt for continuation, we don't let CR repeat the previous
2467 command, once we get back to a prompt. It's too easy to keep
2468 hitting CR, expecting "--more--" prompts, and have some long
2469 command start repeating on you.
2471 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2473 * blockframe.c (frameless_look_for_prologue): Speed up by
2474 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2475 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2476 Define two variants, one faster.
2477 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2478 and return zero, rather than giving an error.
2479 (setup_arbitrary_frame): Initialize the PC in the new frame.
2480 (skip_prologue): Add a second arg saying whether we're just
2481 checking for a frameless function or not.
2483 * core.c (core_open, core_close, core_xfer_memory): Move
2484 section table pointers and bfd* into the target_ops.
2485 (core_open): Allow errors in shared lib reading, etc.
2486 (core_files_info): Describe shared library sections.
2488 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2489 exec_files_info, set_section_command): Move section table
2490 pointers and bfd* into the target_ops.
2491 (add_to_section_table): Add BFD to section table.
2493 * target.c (target_xfer_memory, target_info): Pass target to
2494 xfer_memory and target_info functions.
2497 * gdbcore.h: Move struct section_table.
2498 * target.h: New home of struct section_table.
2500 * solib.c (solib_add): New argument is the target_ops whose
2501 section list is to be added to, if any. Reallocate the
2502 sections in that target to add any that come from shared libs.
2503 (throughout) so_sections renamed to sections.
2504 (solib_xfer_memory): Deleted.
2505 * tm-sunos.h (SOLIB_ADD): Add target argument.
2506 (SOLIB_XFER_MEMORY): Delete.
2508 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2509 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2510 from target_ops. It's the same on all targets. Add two section
2511 pointers to target_ops.
2513 * stack.c (find_relative_frame): Dump ancient algorithm for
2514 "down", just use handy "next" pointers.
2515 (frame_command): Don't error if there is no stack; let user
2518 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2519 modifies static state in the parent process; new_tty itself
2520 runs in the child and modifies the child's file descriptors
2521 to match the saved static state.
2522 * infrun.c (child_create_inferior): Call new_tty_prefork,
2525 * infptrace.c (child_xfer_memory): Add ignored target arg.
2526 * remote-eb.c (eb_xfer_inferior_memory): ''
2527 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2528 * remote-vx.c (vx_xfer_memory): ''
2529 * remote.c (remote_xfer_memory): ''. Rename from
2530 remote_xfer_inferior_memory.
2532 * main.c (main): Only try to attach "corefile" argument if
2533 it starts with a digit.
2535 * symfile.c (symbol_reloading): New "set/show" variable.
2536 (symbol_file_add): Shorten message about symbol reading.
2537 (add_symbol_file_command): Merge with add_syms_addr_command,
2538 since this should work on all targets now.
2539 (stop_whining): Default to zero, to shut up complaints
2540 about bad symbol tables on many systems.
2541 (free_named_symtabs): Just exit unless symbol_reloading.
2543 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2544 and add comment explaining shared library screw.
2546 * source.c: #if defined => #ifdef.
2548 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2550 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2552 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2554 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2555 (doc/Makefile knows how to make one for local config)
2557 * Makefile.in: use doc/Makefile for doc targets
2559 * doc/Makefile: GDB documentation now has its own Makefile
2560 doc/refcard.tex: renamed from "gdbrc.tex"
2561 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2562 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2565 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2567 * values.c (baseclass_addr): When reading target memory, use the
2568 length of the basetype, not the upper type. We've only malloc'd
2569 enough space for the basetype, leading to errors in free().
2571 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2572 ends up as a function specially, since we know the actual type of
2573 the pointed-to address. This (somewhat) fixes display of
2574 expressions that include misc_function_vector names. Try `cond 1
2575 !strcmp("a","b")' then `i b'.
2577 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2578 The child can be proceeded from inside wait_for_inferior in
2579 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2580 getting skipped in that case.
2582 * expprint.c (print_subexp): Use filtered output, since the
2583 subroutines we call use it, otherwise the output is horribly
2584 mangled, since output of wrappable stuff comes out late.
2586 * Makefile.in: Bump VERSION to 3.98.1
2588 * infrun.c (child_create_process): Use execlp to find the
2589 shell to exec our target program. This requires some fiddling
2590 with `environ' since there is no execlpe().
2592 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2594 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2595 Minor rearrangement of refcard permits two new make targets--
2596 gdbrc.dvi DVI output for refcard, using CM fonts
2597 gdbrc.ps PostScript refcard, using PS fonts
2599 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2603 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2604 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2606 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2608 * doc/gdb.texinfo: last changes for release.
2609 Minor typo and formatting fixes; incorporated most fixes remaining from
2610 filed mail commenting on earlier drafts.
2612 Added warnings: pipes don't work in run command;
2613 conditions are converse of assertions;
2614 step over fn without debug info goes to next fn;
2615 vars may have "wrong" values near fn entrance, exit
2617 Added example from Kingston on printing repeated nonadjacent values
2619 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2620 shell mode for signals
2622 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2623 doesn't sound so much like its parent "Stopping and Continuing"; also
2624 moved entries on continue to top of section, so they don't get lost.
2626 Improved installation directions in appendix, added manual formatting
2629 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2631 * configure.in: Remove xm.h and tm.h even if we aren't linking
2632 new ones, so "./configure sun4; ./configure none" does the right
2633 thing. Assume that alldeps.mak and depend are already built in
2634 srcdir, and avoid running "make" (particularly "make depend",
2635 which involves "gcc") from inside configure. Build Makefile
2636 directly rather than building Makefile.conf first.
2637 * configure: Regenerate with above changes.
2638 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2639 to 3.98. Revise gdb.tar.Z procedure to produce a file
2640 called gdb-$(VERSION).tar.Z but which unpacks into a
2641 directory called "gdb". Move non-source files out of
2642 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2643 (depend): Don't try to do "gcc expread.y".
2644 (expread.o): Update dependencies by hand.
2646 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2649 Fixed a variety of small typos that prevented info from formatting
2650 cleanly; altered too-long heading for GPL Appendix, as discussed
2651 w/RMS; Changed date on cover to July 91.
2653 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2656 (1) Applied some fixes due to comments from Larry Breed (easier ones
2657 through chapsec 5.2)
2658 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2659 it's broken in latest texinfo
2660 (3) Introduced *some* use of [] for optional arguments, where
2661 explanation is not simpler by listing cmd w arg and cmd w/out arg
2662 separately. Still not using @deffn.
2663 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2664 couple of headings are too long. Need patches to texinfo or revision
2667 * Partial update to README (which still needs work for this
2668 release!): (1) use of configure corrected for new script,
2669 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2671 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2673 * symtab.c (lookup_symbol): Don't complain right off about
2674 no debug symbols; use the misc function vector first.
2675 (list_symbols): Use misc function vector to find symbols
2676 that don't have debug info, and print them.
2677 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2678 PC range doesn't match symtab PC range, as it does on the
2679 MIPS because our symtab reading isn't perfect.
2681 * dbxread.c (dbx_symfile_read): Make warning about
2682 "no debug symbols" slightly nicer.
2684 * source.c (select_source_symtab): If "main" symbol exists,
2685 but decode_line_spec can't find line info, don't just return
2686 a zero; try other source symtabs or give an error.
2688 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2689 their low addresses first, then rip through fixing high addrs.
2691 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2692 <runene@ifi.uio.no>.
2693 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2695 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2697 * Minor, mostly mechanical, cleanup of doc subdir for clean
2698 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2699 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2701 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2703 Mostly MIPS and general symbol-reading fixups.
2705 * doc/gdbint.texinfo: Add documentation on symbol-reading
2708 * mipsread.c: Remove kludges around #include "ecoff.h".
2709 Remove redefinitions of a_magic, etc, no longer used.
2710 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2711 Fix global overview comments to match symfile.c protocol.
2712 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2713 (mipscoff_symfile_read): Eliminate unused code. Avoid
2714 sorting all the symtabs, when all we have read here is psymtabs.
2715 The symtabs are sorted as they are created anyway. Tell
2716 condense_misc_bunches whether we're mainline.
2717 (psymtab_to_symtab_1): Pass filename when recursing, to make
2718 stack trace more informative.
2719 (parse_partial_symbols): Assume cur_hdr as argument.
2720 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2721 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2722 the TYPE_NAME of char *, since that's done in symfile.c.
2723 (free_numargs, parse_symbol, add_symbol, add_block,
2724 shrink_linetable): Declare these fns void.
2725 (upgrade_type): Convert tree of if's to switch. Clean up
2726 bogus "off == 0" handling with a complaint. Avoid setting
2727 field bitpos and bitsize of array with lower and upper bounds.
2728 Check specified bitsize of elements against their actual type's
2729 bitsize, and complain if different. Complain about unknown
2731 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2732 (psymtab_to_symtab_1): Print names of subsidiary files that
2733 are being read in. FIXME, we read far too many files. This code
2734 is not the problem, the problem is in parse_fdr where the psymtabs
2736 (cross_ref): Result should indicate that we used one aux entry
2737 normally, or two if we encountered a "next" entry. This used
2738 to leave the caller pointing at the wrong aux entry.
2739 (add_symbol): If overflowed cur_block, reallocate it larger,
2740 chase all pointers to it, and complain(), rather than clobber memory.
2741 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2742 (new_field): Only allocate one field initially, not two.
2743 Pull ++ out of macro argument. Simplify.
2744 (_initialize_mipsread): Avoid initialization of importd
2745 global_psymbols and static_psymbols.
2747 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2748 to properly set pst->symtab; avoid searching for it.
2749 (symfile_fns): Improve comments, add a FIXME.
2750 * dbxread.c: Update comments to reflect symfile protocol.
2751 (read_ofile_symtab, end_symtab): Return the symtab.
2752 (psymtab_to_symtab_1): Set pst->symtab.
2754 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2755 whether we're mainline.
2757 * symfile.h (sym_fns): Remove unused sym_discard member.
2758 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2760 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2761 the environment variable is not.
2762 * infcmd.c (finish_command): Use filtered printfs.
2763 * cplus-dem.c: Add struct tags to a few unnamed structs.
2764 * valops.c (value_coerce_array): Improve comments.
2765 * valprint.c (type_print_varspec_suffix): Print array size only
2766 if greater than zero.
2767 * m88k-tdep.c: Shift some lines left by one space, that had
2768 apparently been trashed at some point.
2769 * TODO: More things to do, a few got done.
2771 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2773 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2774 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2776 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2777 * expread.y, findvar.c, symmisc.c: Ditto.
2778 * printcmd.c (address_info): Update printed forms of LOC_
2779 symbols. Elim LOC_EXTERNAL.
2780 (print_frame_args): Keep track of param stack offsets before
2781 re-looking up to find the local register param is kept in.
2783 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2784 Further integration of mipsread into gdb. Eliminate unused
2785 routines, duplicate declarations. Handle static symbols in
2786 psymtabs as well as external symbols. When reading symtabs,
2787 insert symbols into the correct block (global, static, or a local
2789 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2791 (mipscoff_symfile_read): Don't call select_source_symtab.
2792 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2793 rather than SYMBOL_VALUE.
2794 (parse_external): Comment clobbering of top_stack.
2795 (parse_partial_symbols): Update comments. Allocate and parse
2796 static symbols as well as external symbols. FIXME, enum values
2797 are not handled in this pass, but should be. Inline new_psymbol.
2798 Use SYMBOL_VALUE_ADDRESS.
2799 (psymtab_to_symtab_1): Read symbols into global static block
2800 by default (until enter some function's local block context).
2801 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2802 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2804 * source.c (select_source_symtab): Select a source symtab
2805 from either the symtabs or, failing that, the psymtabs.
2806 (list_command): Update error message.
2807 (forward_search_command, reverse_search_command): Use getc, not
2808 fgetc, for speed. FIXME, add comment about buffers that die if
2809 overrun by long line.
2811 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2812 by an entire word, which is not portable, if we have a 32-bit
2813 field. (Code in dbxread.c already turns such bitfields, if
2814 aligned, into ordinary ints, but fixing this will help for other
2815 symbol formats and for future changes.)
2816 * core.c (core_open): Handle ANSI const brain death.
2817 * utils.c (vprintf): Fix varargs typo.
2819 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2821 * findvar.c (find_var_value): Handle &function better.
2822 * TODO: Document work needed on &fn and &array.
2823 * printcmd.c (print_address_symbolic): New arg is the prefix
2824 to print if a name is printed.
2825 (print_address_demangle): Honor "set print address" now.
2826 Use new arg above to improve spacing of output.
2827 * valprint.c (val_print): When printing function pointers,
2828 print symbolic form too.
2829 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2831 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2833 * core.c (memory_error): Reword error msg to mislead less.
2835 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2837 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2838 parse_partial_symbols): Use newer BFD internals (external_filehdr
2839 and external_aouthdr), byte-swap the fields that we care about
2840 before using them, and make the file header data local to
2841 read_the_mips_symtab rather than global.
2843 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2845 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
2846 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
2848 * main.c (command_line_input): Flush stdout and stderr
2849 before every call to readline. This reportedly fixes a bug
2850 that comes up in Sys V running emacs-gdb and/or xxgdb,
2851 when stdin/out are pipes or sockets.
2853 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2855 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
2856 Avoid declaring Makefile dependencies, because GNU Make stupidly
2857 tries to update it if we do.
2859 * coffread.c: Revise for minor changes to bfd internal coff
2862 * configure: If -template= is given a relative path, make it
2863 absolute before recurring in subdirectories.
2865 * configure, configure.in, Makefile.in: Install "configure" script
2866 as replacement for config.gdb.
2867 * config.gdb, Makefile.dist, Makefile.sdir: Remove
2868 * README: Update for configure, mostly. FIXME.
2870 * Add dec3100 as equivalent to littlemips. Indicate in all host &
2871 target config files that they are for the host. When the lines
2872 get copied into the Makefile, this makes it more obvious what's
2875 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2877 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
2878 tabs, which end up in the disassembler output inadvertently.
2880 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2882 Make it compile cleanly in an ANSI GCC2 environment.
2884 * blockframe.c: <stdio.h>
2885 * cplus-dem.c: free takes a void *, ifdef __STDC__
2886 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
2888 * defs.h (alloca): Avoid doing anything if alloca already def'd.
2889 * stddef.h, stdlib.h: Remove these files.
2890 * symtab.c: Avoid declaring qsort, close.
2891 * symfile.c: Avoid declaring close.
2892 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
2893 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
2895 Assorted other changes.
2896 * dbxread.c: include "libaout.h", not "liba.out.h".
2897 * printcmd.c (print_frame_args): Set recurse properly for
2898 indentation of struct and array parameters.
2899 * valops.c (value_cast): Allow cast to void.
2900 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
2901 single_step() in a target-independent fashion.
2902 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
2903 set up to be ready to continue. This makes us target independent.
2904 * infptrace.c (child_resume): Remove call to single_step; now
2905 can single step a SPARC target of any kind.
2907 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2909 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
2910 docn into separate sections---basically chapters, plus two loose
2911 pieces that can be configured to go in different places. This
2912 allows GNU m4 to preprocess the manual without coredumping.
2914 * Makefile.dist: tell TeX where to find texinfo.
2916 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2918 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
2919 the new target "rdl-apps.texinfo" which captures the Makefile
2920 variable that records where to find the Readline libraries.
2922 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
2924 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
2925 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
2926 * defs.h (const, volatile): Only define if not already defined.
2927 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
2929 * README: Update for release 3.95.
2930 * config.gdb: Don't create readline dir in subdir builds.
2931 * main.c: Include with "..." form for non-system include files,
2932 so "gcc -MM" for "make depend" works.
2933 Include readline files with "...h" rather than <readline/...h>.
2934 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
2936 * coffread.c: Undo minor damage done by Rich Pixley. Use
2937 different internal and external representations of COFF
2938 data structures. Use new BFD routines for swapping them in and
2940 * symfile.c (free_named_symtabs): Avoid freeing file names that
2941 are null or empty. Old i960 tools seem to produce files that
2942 claim to have empty names, causing each successive file read
2943 to blow away the previous one.
2944 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
2945 Move deferred_stores to top of file, but don't separate its
2946 #define's from its variable. Add commentary.
2947 * Makefile.dist: Fix Rich damage; undo "configure" changes in
2948 favor of keeping the (working) config.gdb. Move readline
2951 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
2953 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
2955 * infptrace.c (fetch_registers): no result, since now void.
2956 * tconfig/news: target depends on m68k-tdep too.
2958 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2960 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
2963 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
2964 applied various small fixes due to or inspired by RMS comments
2966 * doc/gdb.texinfo: finished using all RMS comments, save those for
2967 appendices on readline and cmd history (which are in other source
2970 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2972 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
2973 chapter 9; (2) documented 'break' command's menu mode for
2974 overloaded names, in response to hgs problem report C++ p-31
2976 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2978 * doc/gdb.texinfo: (1) better introductory example; (2) more
2979 consistent use of @code, @samp, @file, @kbd throughout; small
2980 cleanups to first three nodes; (3) new "Contributors" node;
2981 (4) Appendix, Renamed Commands; (5) divert specialized startup
2982 instructions to "Targets" chapter for generic manuals, while
2983 leaving them up front for manuals specific to specialized
2984 environments; (6) apply fixes from RMS comments through chapter 4.
2986 * pretex.m4: modify explanatory text slightly (and redefine
2987 "regexp") to keep GNU m4 from complaining. (It still crashes
2988 later, but one step at a time...)
2990 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
2992 * readline/readline.c (update_line): Avoid dereferencing a pointer
2993 before comparing it to its bounds. Saber caught this.
2994 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
2995 and only set PC if tgetstr returned non-null. Saber caught this.
2997 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
2999 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3000 stuff for config manual) here where it counts; updated
3001 to use new subdir structure (gdb/doc/).
3003 * Makefile: generated from above via
3007 * gdbint.texinfo: added instructions on generating gdb.info* files
3008 locally for release. These are ordinary info
3009 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3010 Makefile)---but due to use of texinfo 2, can't count on makeinfo
3011 to generate these, so we distribute them already formatted.
3013 * gdb.texinfo: included full Info node and menu crud (as generated
3014 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3016 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3017 put in comments-for-future gdb.info target (one day makeinfo will
3020 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3022 * gdb.texinfo: Updated to include new or old undocumented
3023 commands, at least the following (perhaps some others I forgot to
3024 record): info f, info float, info path, info program, info s, info
3025 set, info source, info terminal, info types, info user, set/show
3027 Also covered all recent GDB command renames for v4.
3029 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3031 * mipsread.c: Rather than keeping count of how many symtabs
3032 and psymtabs we have, for sorting purposes, count them when
3033 we need to sort. This fixes bug in rereading of symbol tables.
3035 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3037 * infcmd.c: renamed "info path" to "show paths"

3052 symtab.h, target.c, target.h: Lint.
3053 * core.c: setup and select frame after reading shared libs,
3054 else reading shared libs will clobber them. Lint.
3055 * utils.c (error): Force out any buffered wrap text.
3057 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
3059 * remote.c: Remove decls of memory_insert_breakpoint
3060 and memory_remove_breakpoint, no longer used. (Suggestion of
3063 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
3064 to make it easier to interface to "configure"'d libraries.
3066 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
3068 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
3069 aliases for set/show print.

3573 New function to give correct error message.
3575 Thu Apr 11 17:19:41 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3578 target.c: Add target_preopen and target_command.
3580 (add_target): Call add_cmd and mess with targetlist->doc.
3581 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
3582 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

3607 * symmisc.c (same): same.
3608 (free_symtab): Make non-static.
3609 * symtab.h (free_symtab): Declare as exported void fn now.
3610 * dbxread.c (end_symtab, end_psymtab): Change comments.
3611 (initialize_dbxread): Call dbx_new_init() in case the first
3612 command is add-symbols.
3613 * target.c (dummy_target): Permit add_syms_addr_command.
3615 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3617 Permit symbols to be superseded when new symbol files have
3618 been read in, particularly for VxWorks.
3620 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
3621 to the main file, as well as to include files. Also, put global
3622 functions into the global psymtab, to make "i fun" work.
3623 (end_psymtab): Free named symtabs and psymtabs for a file, once a
3624 new psymtab for it has been read.
3625 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
3626 a file, once a new symtab has been read for it.
3627 * mipsread.c: FIXME. We need to do the same for MIPS, but it
3628 looks harder to determine the top-level block before it's been
3629 queued to the psymtab list.
3631 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
3632 If we have wiped out any old symbol tables, clean up at end of
3634 (symbol_file_command): Don't reference symfile_fns if it's zero.
3636 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
3637 defines for the blocks of a blockvector that contain global and
3638 file-static symbols and the first of the smaller scope contours.
3639 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
3640 decode_line_1, make_symbol_completion_list): Use the above.
3641 * coffread.c (end_symtab, patch_opaque_types): Ditto.
3642 * dbxread.c (end_symtab): Ditto.
3643 * expread.y (block): Ditto.
3644 * mipsread.c (throughout): Ditto.
3645 * symmisc.c (free_named_symtabs): Ditto.
3647 * symtab.c (list_symbols): Process the first symbol of the
3648 static psymbols list.
3649 (types_info): Restore this function from its untimely #if 0.
3650 It's not perfect, but it is better than nothing.
3651 (_initialize_symtab): Restore "info types".
3653 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3655 * m68k-stub.c: Remote stub for 680x0's, created from
3656 rem-m68k.shar (which is removed).
3657 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
3658 Remove RCS log stuff now that we use CVS and it blows our diffs.
3660 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3662 * symmisc.c (free_named_symtab): Make it work, in its current
3663 kludgy fashion. Change result to indicate if we blew away bkpts.
3664 * dbxread.c (end_symtab): Accumulate result from
3665 free_named_symtab and print warning if we blew user's state.
3666 * symfile.h: free_named_symtab now returns an int.
3668 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
3670 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
3671 is the first symbol read, even if not mainline.
3672 (dbx_psymtab_to_symtab): symfile might be zero, cope.
3673 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
3674 (set_section_command): New command ("section xxx yyy" -- should
3675 be renamed to "set section xxx yyy" FIXME) which sets the
3676 base address of a section of the exec file, overriding the
3677 virtual address that BFD reports.
3679 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
3681 * exec.c: Add add_syms_addr_command to exec_ops, so you can
3682 load symbols at any address while examining an exec file.
3684 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3686 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
3687 for printing the float info is host-dependent, not
3688 target-dependent. FIXME.
3689 * i386-pinsn.c: Move #includes to top, remove useless ones.
3690 * i386-tdep.c: Don't bother including <.../reg.h> since we
3691 don't use it (and it doesn't exist on host systems).
3693 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3694 Convert negative numbers properly.
3695 (ieee_test): Make numbers really random; fix format arg.
3697 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3698 * core.c (core_detach): Unpush core_ops, which might not be on
3699 top. We used to just pop the top, which broke things. Don't
3700 need dont_repeat() any more.
3701 (core_file_command): Psst! Don't repeat it.
3702 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3703 * expprint.c (print_subexp): Avoid switch fallthru on
3704 BINOP_ASSIGN_MODIFY, so we can print += and such.
3705 * frame.h: Fix typo.
3706 * inflow.c (kill_command): After killing inferior, print our
3707 current frame in the core file, if we have one.
3708 (generic_mourn_inferior): When inferior dies, either select
3709 the current frame (in the new target, e.g. core file), or
3710 set both the current and selected frames to NULL.
3712 Changes from Peter Schauer.
3714 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3716 * Make all file names fit in 14 characters (sigh and damn!):
3717 mv hp300hpux-xdep.c hp300ux-xdep.c
3718 mv symmetry-xdep.c symm-xdep.c
3719 mv symmetry-tdep.c symm-tdep.c
3720 mv convex-opcode.h convx-opcode.h
3721 mv tm-vxworks960.h tm-vx960.h
3722 mv tm-vxworks68.h tm-vx68.h
3723 mv Makefile.srcdir Makefile.sdir
3724 mv gdb-int.texinfo gdbint.texinfo
3725 mv remote-sa.m68k.shar rem-m68k.shar
3726 mv remote-multi.shar rem-multi.shar
3727 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3728 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3729 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3732 * command.c (user_info_1, user_info): New command for listing
3733 the user-defined commands.
3735 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3737 * dbxread.c (really_free_pendings): Clear file_symbols
3738 and global_symbols after freeing them; otherwise, running
3739 this function twice (if it appears twice on the cleanup
3740 chain), we try to free things twice.
3742 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3743 based on text_addr (the address of text in core), not on addr (the
3744 offset between text in the .o file and in core). This change
3745 is from Peter Schauer.
3747 * main.c: Define ALL_CLEANUPS as a cast of zero.
3748 (return_to_top_level): Use it.
3749 (main): Do all cleanups after each command run as part
3750 of the gdb startup sequence. Also do all cleanups before
3751 entering the command loop, and every time we exit the command
3752 loop and reenter. Before, the cleanups from the startup sequence
3753 were being left undone until the first error!
3754 (command_loop): Rename do_nothing cleanup to command_loop_marker
3755 so we can see it easily when examining the cleanup chain.
3756 (init_signals): Add another do_nothing for signal handling.
3757 (quit_command): Only try to kill target if it has execution.
3758 Problems in the target stack got us into a state where
3759 inferior_pid was nonzero but none of the targets had execution.
3760 In this state you couldn't exit gdb.
3762 * dbxread.c: Two changes from Peter Schauer.
3763 (echo_command): Fflush output after an echo command.
3764 (show_history): Pass all args to cmd_show_list.
3766 * utils.c (init_malloc): Call mtrace to turn on tracing
3767 if the environment variable MALLOC_TRACE is set to a file name.
3768 * mtrace.c: Add source file which provides a log of every malloc,
3769 free, and realloc to a trace file.
3770 * mtrace.awk: Add source file which analyzes the trace file.
3771 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3772 (VERSION): Roll to 3.94.3.
3774 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3775 (check_duplicates): Don't bother with watchpoints.
3776 (set_raw_breakpoint): Comment about danger of this routine.
3777 (watch_command): Parse and eval all args before calling
3780 * solib.c (find_solib): Avoid error in referencing memory to
3781 see if any more shared libraries have been added. This is
3782 particularly useful if the target has terminated. Bug reported
3785 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3786 in bringing up 3.94.2 on the Sun-3.
3788 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3789 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3790 expression (in scope) before reenabling watchpoint.
3791 * signame.c (init_sigs): Add missing declaration of i, fix
3792 sys_siglist declaration.
3793 * source.c (list_command): Fixed range computation to use
3795 * stack.c (backtrace_command): Do not allow command if target has
3796 no stack, print informative error message.
3797 * target.c (target_command): Do not write into command line
3798 because this fails if the target command is used in a user defined
3799 command. [This change was enhanced by gnu to support any-
3800 unique-prefix matching on target names.]
3801 * valops.c (value_struct_elt): Avoid infinite loop on an
3802 erroneous attempt to print the member of function (try p main.p).
3804 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3806 * expread.y (name_no_typename): Avoid reduce/reduce errors
3807 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3808 Since the GDB parser really doesn't use name_no_typename in a
3809 name-only context, the parser can't tell the diff between
3810 names and numbers here. Avoid allowing a name_no_typename
3811 to be a NAME_OR_*INT to resolve the conflict.
3813 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3815 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3817 * valprint.c (val_print_fields): bitfield printing didn't handle
3818 byte order. Indirect through a few more fns to cope.
3820 * values.c (modify_field): also cope with byte order.
3822 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3824 Cleanup for release 3.94.2:
3826 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3827 include files. Roll version to 3.94.2.
3829 * coffread.c (init_stringtab): Read length into unsigned char
3830 array before swapping; don't assume 32-bit longs.
3832 * target.c (target_info): Don't bother with get_sym_file, just use
3833 the symfile global variable.
3834 * symtab.h, symfile.c (get_sym_file): Delete it.
3836 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3837 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3838 (read_type): Replace one more error() with complain().
3840 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3842 * i960-tdep.c: Fix copyright attribution.
3844 * config.gdb: Quote all backquotes in doublequotes. You can
3845 quote me on that. BSD 4.4 shell found this one.
3847 * infptrace.c (throughout): The third argument to ptrace is an
3850 * infrun.c (wait_for_inferior): When program has terminated, we
3851 have to call target_terminal_ours before we pop that target off
3852 the stack (e.g. before a call to target_kill or
3853 target_mourn_inferior). This fixes problem where a program
3854 terminates, then GDB stops for (tty output) and you have to type
3855 "fg" to the shell to resume it. FIXME: This code for what to
3856 do after termination really should be in normal_stop instead.
3858 * gdbcore.h (read_memory_check): Change declaration; it changed
3861 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
3862 4.4 prereleases, this avoids a bug in their sgtty compatability
3864 * remote.c: Use terminal.h rather than hand-rolling the same.
3866 * signame.c, signame.h (psignal): Arg is unsigned, not int.
3867 * utils.c (strsave, strstr): Fix arg types.
3868 * valprint.c (val_print): lint
3870 MIPS symbol table support from Per Bothner:
3872 * symfile.c (symtab_fns): Remove initializer table that needs to
3873 be hacked for each new symbol file format supported.
3874 (add_symtab_fns): New function, chains symbol table
3875 handlers into the global list.
3876 (symfile_init): Search this list.
3877 * symfile.h: Add next pointer, declare add_symtab_fns.
3878 * coffread.c (_initialize_coffread): Call add_symtab_fns.
3879 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
3881 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
3882 symbol *). Thus, we no longer need the hack to trash
3883 pst->filename. Good, since that hack confused code in symfile.c!
3885 (reorder_symtabs, destroy_all_symtabs): Removed static
3886 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
3887 Instead, the latter now uses a temporary array (stack-allocated
3888 from an obstack, and then freed).
3890 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
3891 haven't been set in the outermost stBlock of a procedure. This was
3892 a problem with f77 binaries on Ultrix 4.?.
3894 (new_symtab, new_symbol, new_type): Continue changing code to use
3895 obstacks more and otherwise conform to dbxread internal style.
3896 Made the free_code of symtabs be free_linetable (as in dbxread)
3897 instead of free_contents. This implies memory leaks when reading
3898 a new symbol table, until the conversion is finished. Did change
3899 (struct symbol) and (struct type) to be allocated on the
3900 symbol_obstack. Blocks and blockvectors are among the things
3903 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
3904 tested much, but it solved one problem (reported by Meissner), and
3905 cleans up some other things. The problem happened when an
3906 included file contains actual code (functions) and not just
3907 definitions. The mips coff is a little inconvenient there, since
3908 it may cause a procedure to be mapped to the wrong psymtab.
3910 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
3911 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
3912 this will need work for the new core paradigm.
3914 Opcode patches from the net:
3916 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
3917 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
3918 missing altogether - they are added here. From Bruce Bauman.
3919 * mips-opcode.h: The low mask for C0 instructions was too small.
3920 From Garrett Lau. I modified the fix to check the entire 32-bit
3923 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
3926 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3928 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
3930 * dbxread.c (read_type): Pointer subtraction (value_sub in
3931 valarith.c) sometimes failed because the types of the
3932 pointers being subtracted were not identical.
3933 These differed because dbxread.c was allocating pointer types
3934 using dbx_alloc_type+smash_to_pointer_type instead of
3935 lookup_pointer_type. I failed to find a justification for the
3936 former, so I changed it to use the latter. Similarly, I
3937 replaced smash_to_function_type by lookup_function_type,
3938 and smash_to_reference_type by lookup_reference_type.
3940 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
3941 _initialize_mipsread): corresponding changes.
3943 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
3945 * source.c (mod_path): Do tilde_expand on each component of the path,
3946 rather than on the (list of) paths as a whole.
3947 (print_source_lines): Set first_line_listed in addition to
3948 current_source_symtab and current_source_line. If the source was
3949 not findable, after a "dir" command to fix the problem,
3950 a "list" would get the wrong lines.
3952 While I was there... (gnu):
3954 * dbxread.c (read_type): Change error to complaint.
3956 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3958 First attempt at detailed understanding of symbol table memory alloc.
3960 * dbxread.c (dbx_symfile_read): Free our string table if we
3961 aren't the mainline. Free the "info" struct since we're done with
3963 (init_psymbol_list): Free any previously allocated psymbol lists.
3964 (): FIXME: Should realloc-down the psymbol lists when done reading
3965 the main symbol file?
3967 * symmisc.c (free_symtab): Free fullname field too.
3969 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
3970 (REGISTER_ADDR): Make result type unsigned int.
3972 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
3973 define REGEX must also define REGEX1 (its dependency).
3975 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
3977 * tconfig/i960: No longer works, points you at vxworks960 or
3980 * xgdb.c, XGDB-README: Remove file. Users can get the much
3982 * Makefile.dist: Remove all trace of xgdb.
3984 * breakpoint.c (breakpoint_1): Pass demangle arg to
3985 print_address_symbolic.
3986 (clear_breakpoints): Remove unused function.
3987 (breakpoint_re_set_one): Guts of breakpoint_re_set.
3988 (breakpoint_re_set): Use catch_errors to do them all anyway.
3990 * gdb-int.texinfo (Host versus Target): Add section on what is
3991 a "host" feature versus what is a "target" feature.
3993 * infcmd.c (path_command, path_info): Handle the PATH variable
3994 (object search path) as conveniently as the source search path.
3995 * environ.c (set_in_environ): Set some vars in GDB's environment,
3996 in addition to the child's. PATH, G960BASE, G960BIN for starters.
3997 * source.c (mod_path): New function, from guts of
3998 directory_command, modifies a path. Used by path_command.
3999 (directory_command): Call it.
4000 * defs.h (strsave): Declare.
4002 * utils.c (sevenbit_strings): Add new printing option.
4003 (printchar): Use it.
4004 (strsave): Provide this handy helper routine.
4005 (set_width_command): Rename set_screen_width_command.
4006 (_initialize_utils): "set screen-width" => "set width";
4007 "set screen-height" => "set height"; add sevenbit-strings.
4009 * infcmd.c (do_registers_info): Print floating point registers
4010 in raw hex as well as float format, regardless of whether it is
4011 a "virtual" convertible register.
4012 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
4013 regs as a double, just in case it's being used that way.
4014 * values.c (unpack_long): Comment on array/function coercion.
4015 (unpack_double): Argument is in target byte order now. For
4016 integer arguments, just call unpack_long and float the result.
4017 * m68k-tdep.c: include defs.h for "const" handling.
4018 * remote-nindy.c: Use ieee-float stuff.
4019 (nindy_fetch_registers): Unpack double regs to host double, then
4021 (nindy_store_registers): Pack extendeds to host double, flip
4022 around by misusing unpack_double, send as target double.
4024 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
4025 zero, as when stopped at the first instruction of a process.
4027 * blockframe.c: Fix filename in comment (param.h => tm.h).
4028 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
4029 * tm-68k.h: Fix typos.
4031 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
4033 Changes from a bringup on the DEC Vax under Ultrix 4.0.
4035 * coredep.c (fetch_core_registers): Pass end-address of register
4036 section to register_addr as expected. Don't call supply_register
4037 if we'd just pass it garbage.
4039 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
4041 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
4043 * target.c (push_target, target_info): Cast enums to int for < or
4046 * stack.c (print_frame_info): Identify source file & line
4047 even if we can't print it.
4049 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
4051 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
4053 Clean up IEEE floating point support.
4055 * ieee-float.h: New file.
4056 * ieee-float.c: Write real routines to convert between host
4057 doubles and various target IEEE extendeds.
4058 * m68k-xdep.c: Eliminate assembler code for extended floats.
4059 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
4060 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
4061 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
4062 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
4063 double_to_ieee_extended.
4064 * i960-tdep.c: Define ext_format_i960.
4065 * m68k-tdep.c: Define ext_format_68881.
4066 * sparc-tdep.c: Define ext_format_sparc, though unused.
4067 * Makefile.dist (HFILES): Add ieee-float.h.
4068 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
4071 Obsolete the "coffstrip" program in favor of using BFD's strip.
4073 * nindy-share/coffstrip.c: Remove file.
4074 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
4075 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
4076 * tconfig/nindy960: Remove reference to coffstrip.o.
4078 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
4080 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4082 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
4083 * dbxread.c: Remove static symfile_bfd.
4084 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
4086 * inftarg.c (child_detach): Pop the child_ops vector if the
4087 detach is successful.
4088 * remote-nindy.c (nindy_create_inferior): Don't push a new
4089 nindy_ops since nindy uses the same one for execution and memory
4091 * core.c (core_ops): Use child_attach and child_create_inferior
4092 rather than default attach and create_inferior functions.
4094 Handle floating point registers in core files.
4096 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
4097 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
4098 This version untested since BFD doesn't yet support sun3 core
4100 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4101 conventions. Fix comments and style. This version has not
4102 been compiled yet, since we have no HP inhouse.
4103 * core.c (get_core_registers): Look for two sections, ".reg"
4104 and ".reg2", and pass both to fetch_core_registers sequentially.
4106 Revise directory path yet again.
4108 * source.c (forget_cached_source_info): Not static any more.
4109 (init_source_path): New default source path is "$cdir:$cwd".
4110 (dir_command): Handle variable arguments ($cdir, $cwd).
4111 (source_info): Print "Compilation directory" rather than
4112 "Originally compiled in" to remind people of $cdir.
4113 (openp): If the path contains $cwd, use current directory.
4114 (open_source_file): If compilation directory is known, replace
4115 first $cdir in path with the compilation directory.
4116 (print_source_lines): Even if we can't print the lines, set the
4117 current symtab and line for future commands like "info source" or
4118 "breakpoint". Also, error message now contains the file name,
4119 line number, and file access error message.
4120 (_initialize_source): Fix help text to describe changes.
4121 * main.c (cd_command): Forget cached source info when we chdir.
4122 * utils.c (strstr): Add simple implementation.
4124 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
4126 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4127 Byte-swap COFF symbol tables if necessary when reading them in.
4128 Use complain() to replace error message in one spot. Needs
4129 corresponding change in bfd/coff-code.h to make some symbol
4130 swapping routines non-static.
4132 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4134 Merge changes from Eirik Fuller, for UTek.
4136 * defs.h (errno): Add declaration.
4137 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
4138 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
4139 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
4140 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
4141 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
4142 declarations of errno.
4144 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4146 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4147 <rpc/rpc.h> and <rpc/types.h>.
4149 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4151 * i960-tdep.c (examine_prologue): Add new argument limit,
4152 which stops the scan at the end of the prologue, or at the PC.
4153 This fixes a problem where it walks down into the code for the
4154 user's statements if that code looks like function prologues.
4155 Mark Fox and I have been bouncing this code back and forth, making
4156 small changes to it. Callers changed to match.
4158 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4160 Cleanup for gdb-3.94 release final:
4162 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4163 the .c files from vx-share and nindy-share, from the various
4164 macros, since they are not found via ALLDEPFILES.
4165 (SFILES): Add tm-i960.h.
4166 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4167 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
4169 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
4170 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
4172 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
4174 * am29k-tdep.c: Add contribution line.
4175 (examine_prologue): Cache information about function prologues in
4176 the misc-function-vector to avoid lots of references over the
4177 serial line while examining instructions.
4179 * core.c (core_close): New function made from cleanup_core.
4181 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4182 remote-vx.c, remote.c, target.c, target.h,
4183 Update target_ops vector to add attach, close, and load entries.
4184 Use add_syms_addr_command, not add_file_addr_command, for
4185 add_file. Break out close routine from existing code.
4187 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4188 they are in an obstack.
4189 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4191 (define_symbol): Add symbol type parameter; change callers;
4192 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4193 it to influence the symbol class on the i960.
4194 (define_symbol): Swap LOC_CONST's into target byte order.
4196 * exec.c (exec_close): New function.
4197 (exec_file_command): Call it.
4199 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4200 Fix byte order of frame pointer.
4201 (read_var_value): Result of 0 if var's value can't be found,
4202 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4203 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4204 (locate_var_value): Use read_var_value and use its lazy address
4205 as the location of the var's value. Lint.
4207 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4210 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4211 obsolete Intel versions in favor of vxgdb versions.
4212 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4213 code dealing with byte order of values, which Intel did in host byte
4214 order rather than gdb-4's target byte order.
4215 (i960_frame_chain_valid): Move to nindy-tdep.c.
4216 (examine_prologue, skip_prologue, frame_find_saved_regs,
4217 frame_args_address, leafproc_return, saved_pc_after_call,
4218 pop_frame): Add vxgdb versions from Mark Fox.
4219 (examine_prologue, frame_struct_result_address): Add code
4220 to deal with the saved value of G13 (struct return address
4222 (frame_args_address): Modify Mark's version to prefer the
4223 saved value over the current value in the topmost frame.
4224 Cache result in the frame info to avoid performance hair in
4226 (print_fault): Add gdb960 code for printing faults.
4227 (_initialize_i960): Actually call check_host.
4229 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4230 add stub routines. FIXME, these currently just return zero!
4232 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4233 (attach_command): Call target_attach, not target_open, now.
4235 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4236 (child_attach): Rename from child_open.
4237 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4238 don't confuse it with a zero step_resume_break_address.
4240 * inftarg.c (child_detach): Eliminate inferior_pid test.
4241 (child_files_info): Clean up message a bit.
4242 (child_ops): Use child_attach, not child_open, to attach.
4244 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4245 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4246 findvar.c to here, since it depends on the contents of the
4247 shadow_contents of breakpoints, but keep if #if 0 since it is
4250 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4253 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4254 (ptype_command, display_command): Eliminate have_inferior_p and
4255 have_core_file_p in favor of target_has_stack or
4256 target_has_execution.
4257 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4258 code for actually finding the values of arguments, though we still
4259 keep track of the maximum stack offset for use in printing unnamed
4260 arguments. Handle missing FRAME_ARGS_ADDRESS.
4262 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4263 (struct nindy_regs): Define registers passed to/from nindy.
4264 (nindy_fetch_registers, nindy_store-registers): Translate between
4265 nindy and GDB formats for the registers.
4266 (dcache_init): Statically allocate the cache, since it was being
4267 allocated by a malloc that was never freed anyway.
4268 (nindy_create_inferior): Error, not core dump, if no exec file.
4269 (nindy_before_main_loop): Use target_load, not target_add_file.
4271 * remote-vx.c (net_load): Specify large timeout for load
4272 requests. Allow user to break out with INTERRUPT.
4273 (net_break): Remove useless code, clean up. Change callers.
4274 (parse-args, skip_white_space, find_white_space): Clean up arg
4275 parsing to cope with quoted strings.
4276 (net_wait, net_quit): Never call error, just return status.
4277 (vx_read_register, vx_write_register): Cleanup status checking.
4278 #ifdef the code based on which CPU we are using (960 or 68k),
4279 FIXME, this should be completely general but it isn't yet.
4280 (vx_xfer_memory, vx_resume): Cleanup status checking.
4281 (vx_run_files_info): Improve message.
4282 (vx_load_command): Renamed from vx_add_file_command. Allow load
4284 (net_ptrace): Remove unused routine.
4285 (vx_wait): Adopt code from vxgdb960 to cope with broken
4286 connections to target machine and prompt to disconnect. Remove
4287 debug printouts. Map some EVENT_'s to SIGnals.
4288 (add_symbol_stub, vx_open): Print names of object files we found,
4289 and "ok" if we read their symbols OK. Clarify output in general.
4290 (vx_attach, vx_detach, vx_kill): Add these commands.
4291 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4292 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4293 "info files" output, and create_inferior, since we already have
4296 * stack.c (frame_info): Replace Frame_unknown with 0.
4297 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4298 (return_command): Pop until the PC matches as well as the FP,
4299 so it works even if the FP is shared with another function,
4300 as in "frameless" or "leaf" procedures.
4302 * symfile.c (load_command): renamed from add_file_target_command.
4303 (add_syms_addr_command): renamed from add_file_addr_command.
4304 (add_syms_command): Stub to call target_add_syms.
4305 (_initialize_symfile): Change command names and descriptions,
4306 add-file => add-syms, and load from alias to its own command.
4308 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4309 maybe_kill_then_create_inferior): Default for attempts to start
4310 a process, if one is already running, is to ask about killing
4311 it and retry if yes.
4312 (upstack_create_inferior): #if-0 it, strata obsolete it.
4313 (push_target, unpush_target, pop_target): to_close() a target
4314 before unstacking it.
4315 (target_info): Renamed from target_files_info.
4316 (_initialize_targets): Rename "i files" as "i target", accessible
4319 * target.h: Improve comments about the target_ vectored routines.
4321 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4322 Convert commenting style to standard GNU style.
4323 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4324 (SKIP_PROLOGUE): No longer a no-op.
4325 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4326 (*_REGNUM): Sort register numbers.
4327 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4328 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4329 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4330 are now 10 byte extendeds, not 8 byte doubles.
4331 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4332 for nindy versus vxworks targets. FIXME, this should possibly go
4333 in the target vector.
4334 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4335 frame_saved_regs and arg pointer with each frame.
4336 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4337 (FRAME_ARGS_ADDRESS): Use cached result.
4338 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4339 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4340 (PRINT_RAMDON_SIGNAL): Call print_fault.
4341 (POP_FRAME): Now works.
4343 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4344 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4345 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4346 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4349 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4350 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4352 * valarith.c (value_subscripted_rvalue): Avoid handling
4353 floats and doubles specially; it gave alignment errors. Lint.
4355 * valops.c (value_of_variable, value_of_this): Error if unknown
4358 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4359 to avoid alignment problems.
4360 (value_print): Handle unknown value address.
4361 (cplus_val_print): Two args are ignored; remove them. Change caller.
4362 (val_print): Use unpack_long rather than pointer-deref.
4365 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4366 to avoid alignment problems.
4367 (value_being_returned): Error if return value unknown.
4368 (set_return_value): Add bogosity warning, FIXME. *
4370 * TODO: A woman's work is never done.
4372 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4373 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4374 Add ieee-float.o to OBS.
4375 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4376 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4377 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4379 Changes to generalize the VxWorks RPC protocol slightly, to handle
4380 i960 as well as 68000.
4382 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4383 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4384 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4385 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4386 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4387 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4388 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4389 so they will move in target byte order rather than network
4390 byte order (happens to be the same).
4392 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4394 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4396 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4399 Add contribution lines to various files, showing where they
4402 * breakpoint.c (break_insn, check_break_insn_size,
4403 read_memory_nobpt): Remove to mem-break.c.
4405 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4408 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4409 entry has bad register number. This change is not
4410 tested in this release, FIXME.
4412 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4415 * value.h: Force value's contents field to be aligned to hold
4416 at least a double or a long long (if supported). This avoids
4417 doing bcopy's in and out of the contents field.
4419 (step_1): Avoid coredump under obscure circumstances when we
4422 * symtab.h (misc_info): Add field to misc function vector for
4423 any kind of cached information the target code desires. AMD
4424 29000 uses this to avoid repeating examine_function_prologue's.
4426 * coffread.c: Lint. Remove static symfile, read_section_header.
4427 core.c (have_core_file_p): Lint: remove.
4428 expprint.c (print_subexp): Lint.
4429 infptrace.c, valops.c, valprint.c: lint.
4431 Roll in changes from vxgdb-5.0.1:
4433 * symtab.h: Comment byte order of each address class. Add
4434 LOC_LOCAL_ARG for frame-relative args (960).
4435 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4436 symtab.c, symmisc.c: ditto.
4438 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4440 * remote.c (remote_resume): Error if resume with a signal.
4442 * symfile.c (prim_record_misc_function): Clear misc_info.
4443 (fill_in_vptr_fieldno): Check stub type of arg.
4445 * valops.c (value_cast): Avoid looking up names of types whose
4446 name we don't know, to prevent coredump. Sun CC produces typedef
4447 rtx and the name of *rtx is zero...
4449 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4451 Roll in changes from final AMD 29000 port (Tiemann).
4453 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4454 for ../include/a.out.encap.h. This might not work now that BFD
4455 is separately compiled. Instead, BFD support for encap will have
4456 to translate machine type 29k into the right COFF_MAGIC.
4458 * infcmd.c: Remove references to inferior_pid that aren't used
4459 in actual ptrace calls; use target_has_execution, etc.
4460 (have_inferior_p): Remove function.
4461 (program_info): Print target info rather than "process number";
4462 avoid gratuitous messages unless from_tty.
4463 (run_stack_dummy, finish_command): Set proceed_to_finish.
4464 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4465 main.c: Lint. Lose have_inferior_p().
4466 inferior.h (have_inferior_p): Remove, lint.
4467 (proceed_to_finish): Add flag to ask that all regs be saved
4468 by normal_stop, for the few commands that need it, speeding up
4469 serial I/O. Add comments to stop_registers.
4471 * remote-eb.c: Remove newline from breakpoint message we grep
4472 for. Never time out when running the user program.
4476 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4478 Roll in changes from vxgdb-5.0.1:
4480 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4481 symbol in its raw form, we are processing an unlinked ".o" file.
4482 See if the target environment has assigned it an address, using
4483 target_lookup_symbol (VxWorks does), and enter it into the symtab
4486 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4487 68k versions for a simpler version that assumes zero FP at bottom.
4488 Fixes bug of truncated stack reports.
4490 * target.h (target_lookup_symbol): Define this routine's args
4491 and result, finally.
4493 * target.c (nosymbol): Default routine for target_lookup_symbol.
4494 (target_default): Default lookup_symbol and call_function too.
4495 (files_info): Only print has_all_memory warning if a non-dummy
4498 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4499 vx_convert_from_virtual): If target does not have floating point,
4500 zero register "values", and avoid doing cross-net conversions.
4501 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4502 (vx_open): Rearrange code that attaches to target and reads
4503 symbols for all loaded modules, to work if some of the modules
4504 are not accessible. Add symbol_stub() and add_symbol_stub()
4505 as callbacks from catch_errors(). Allow connect attempt to be
4506 interrupted painlessly with ^C (FIXME, there are still some bugs
4507 if the interrupt happens during symbol reading.). Print
4508 final message with puts_filtered, since symbol messages are
4513 * main.c (catch_errors): Only print errstring if non-null.
4514 (command_loop): Avoid an ioctl per command to test ISATTY.
4516 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4517 (vx_xfer_memory): Return correct result!
4518 (vx_files_info): Indicate whether target has float or not.
4519 (vx_lookup_symbol): Complain, not error, if target gone.
4520 (vx_open): Print "Connected" msg before disabling immediate-quit.
4521 [FIXME: lookup_symbol and vx_open changes need testing.]
4523 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4524 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4525 contributor lines and update copyrights to 1991.
4527 Changes from an attempted H-PUX host port:
4529 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4530 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4531 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4532 * remote-vx.c: include <sys/time.h> for HPUX.
4533 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4534 "core_file_command" routine to BFD regime. May not work yet.
4536 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4538 * xgdb.c: Replace X10 version with some VJ version.
4539 (FIXME: Its copyright assignment is not on record.)
4540 * xgdb.c: Update include files to X11R4 (Xaw crud).
4541 (xgdb_display_source, create_text_widget): fix call to
4542 get_filename_and_charpos. Rewack source window stuff for X11R4
4543 (gleaned from include files, and "nm's" of binary libraries, since
4544 I had no doc available).
4545 (append_selection, append_selection_word): Disable with FIXME
4546 since R4 changed interface here.
4547 (create_buttons): Add back the old set of buttons.
4548 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4550 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4551 Roll VERSION to 3.94 (not yet final though).
4553 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4555 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4556 obstack_int_grow, obstack_int_grow_fast): Eliminate
4557 cast on left of assignment, which gives MIPS cc fits and is
4560 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4561 F_ALIAS. Use printf, not fprintf, when not passing a file
4563 (compare_opcodes): Check that identical instructions have
4564 identical opcodes, complain otherwise.
4566 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4567 was reported by Roland McGrath.
4568 (unimp): Only match if exactly zero instruction. (Roland)
4569 (branches and traps): Generate all variations of these
4570 instructions with macros, based on a single call that defines
4571 each condition name and its binary representation.
4572 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4574 * valprint.c (val_print_fields): Take, and use, format parameter.
4575 This means that "p/x struct" again prints the elements in the
4576 desired format. Changed callers.
4578 * stack.c (frame_info): Use filtered output, and indicate wrap
4579 points. Remove kludgy formatting designed to avoid line wrap.
4581 * utils.c (wrap_here): If the line is already full (because
4582 we had printed a long indent or long wrapped string), do an
4583 immediate newline-and-indent.
4585 * m68k-pinsn.c (print_insn_arg): Bugfix from
4586 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4587 instruction is incorrectly disassembled as bkpt #8.
4589 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4590 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4591 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4592 and then will dump core (sometimes). I traced it back to an
4593 uninitialized symfile_name in psymtab_to_symtab.
4594 (const_vol_complaint): Add quotes to message.
4595 (define_symbol): Only believe line number if gcc_compiled.
4596 Avoid allocating symbol if we will not return it.
4598 Add target strata support so that newly established targets go
4599 into their right place in the target stack (e.g. a new exec file
4600 doesn't wipe out the ability to access the running process).
4602 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4603 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4604 and initialize it properly in all the targets.
4606 * target.h: Document strata. Change return type of push_target.
4608 * target.c (nomemory): new function for dummy memory access.
4609 (tcomplain): Rename complain, now also used in symfile.c.
4610 (push_target): Push targets within strata. New return value shows
4611 whether new target is on top of stack or not. Always keep dummy
4613 (target_files_info): Ignore dummy target.
4615 * core.c (core_open): Warn user, and skip accessing file, if the
4616 core target is not the topmost target in the stack.
4617 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4620 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4621 target_ops, it doesn't belong there since we have no regs there.
4622 Change name of target from machine => memory to clarify.
4624 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4626 * Freeze version 3.93 for release.
4628 * Makefile.dist: Handle vx-share and nindy-share subdirs
4629 properly when building gdb.tar.Z.
4631 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4632 printed in various places, so I could change just one copy.
4634 * dbxread.c, coffread.c: Change references to bfd->iostream
4635 to cast to FILE *, now that BFD avoids needing types defined
4636 in other header files.
4638 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4640 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4641 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4642 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4643 (actually gcc -Wall).
4645 * dbxread.c: Remove first_global_sym, last_global_sym, since
4646 they are never referenced.
4648 * defs.h (baud_rate): Declare.
4649 main.c: Define it, and add the -b option to set it.
4651 * gdb-int.texinfo: Add text on how to define a new host or target
4652 architecture, prompted by Per Bothner's questions about MIPS
4655 * gdb.texinfo: Document "complaints". Change doc of -q since
4656 gdb no longer prints the copyright and blurb if you specify a file
4657 name to be debugged (just like Emacs). Add doc for Nindy-specific
4658 command line flags for specifying target serial port and such.
4659 Update copyright to 1991.
4661 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4662 has taken over for us the job of ripping up executable files. The
4663 crud caused Per Bothner's port to not compile.
4665 * infrun.c (normal_stop): Avoid printing "Program exited
4666 normally" if we are in batch mode. This allows a GDB which
4667 executes a program on a target system, to behave like a Unix
4668 command (input from stdin, output to stdout, no extraneous
4671 * main.c (main): Allow additional machine-dependent command line
4672 options to be specified with the ADDITIONAL_OPTIONS,
4673 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4674 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4675 processing to occur just before the main loop with
4676 BEFORE_MAIN_LOOP_HOOK.
4677 (main): If a "core file" argument is specified, and it is not a
4678 core file, try it as a process ID to attach.
4679 (symbol_completion_function): Attempt to cope with
4680 "show screen-" TAB, not very successfully. This needs more work,
4682 (batch_file): New function, returns whether we are reading
4683 commands from an interactive tty on stdin, or from somewhere else.
4684 Called by normal_stop since it doesn't get from_tty passed down
4685 to it like many commands do.
4687 * remote-nindy.c: Handle command line options for nindy
4689 (nindy_before_main_loop): Prompt user for tty name if they
4690 don't specify it before getting to the interactive command loop.
4692 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4693 and -r command line options. Also add hook before main loop
4694 to make it easy to specify a tty.
4696 * TODO: More things to do, one done.
4698 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4700 * dbxread.c: Make complaint() calls pass pointer, not struct.
4701 Add complaints about badly formatted C++ type information
4702 (const/volatile indicator, and parse errors resulting in
4703 error_type). Fix C++ virtual member fn comment.
4704 (read_struct_type): Avoid bumping pointer if we got a parse
4705 error; this prevents our walking beyond the end of a string.
4706 Terminate loop on null char as well as semicolon.
4707 (process_one_symbol): Fix the LBRAC fix so that it uses the
4708 last previous SLINE, FUN, or SO record's PC address. C++ debug
4709 symbols did not have SLINE records in a useful order compared
4710 to the LBRAC records.
4711 (define_symbol): Handle "catch" records.
4713 * symtab.c (check_stub_type): Added new complain
4714 `stub_noname_complain' and added a consistency check to
4715 keep the debugger from crashing when finishing from an
4716 exception frame. A real fix will be needed later.
4718 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4720 * infcmd.c (attach_command): Make global.
4722 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4723 but make them easy to comment out. Perhaps later they should
4724 be enabled by what CPU you configure for? FIXME.
4725 (VERSION): Roll to 3.93.
4726 (pinsn.o): Remove rule for obsolete file.
4727 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4729 Run down a problem that manifested by printing the wrong function
4730 name in stack traces of read_ofile_symtab. Turned out that the
4731 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4732 the LBRAC symbol with an address in the *data* segment, which
4733 blew our binary search through the blocks.
4735 * dbxread.c: Use the complain() facility consistently to bitch
4736 about problems in the symbol file we are reading.
4737 (finish_block): Add code to check the nesting of the blocks;
4738 complain and Procrust them to fit if wrong.
4739 (make_blockvector): Check the order of the blocks, complain
4740 [but don't cope] if wrong.
4741 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4742 symbols to be sure their PC value is greater than the last SLINE
4743 (line number) symbol we've seen, complaining and adopting the
4744 SLINE PC value if wrong.
4746 * symfile.h (struct complaint, complaint_root, complain,
4747 clear_complaints): Add.
4748 * symfile.c (complain, complaint_root, clear_complaints): Add
4749 facility to deal with non-fatal complaints and to regularize their
4751 (symbol_file_add): Clear complaint counters to allow new complaints.
4752 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4754 * dbxread.c (dbx_symfile_read): Remember the address and size
4755 of the string table for the main symbol file, so we won't read it
4757 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4758 to avoid reading the string table yet again. Lint.
4759 (throughout): Improve filtered output, including word wrap.
4760 (read_range_type): Improve Bothner's fix to handle other types too.
4762 * utils.c: Improve line wrap implementation. Handle unlimited
4763 width by making chars_per_line unsigned.
4764 (puts_filtered): New, easy, function.
4766 * defs.h (puts_filtered): add.
4768 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4769 call the identical sort_symtab_syms() in symfile.c instead.
4771 * expread.y: Suggest the `file' command rather than `symbol-file'.
4773 * command.h (enum var_types): Add zinteger for seroable
4775 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4776 nested if's into a switch.
4778 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4779 we did not stop because of a breakpoint (it must have been for
4780 some other reason, like a "stepi"), so don't print anything.
4782 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4783 doesn't include <sys/types.h>, old SunOS's require it for
4786 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4788 A test port of gdb-3.92.6 to the Sony NEWS.
4791 Don't normally link in remote- or vx stuff.
4792 Some of it doesn't compile, and it wastes space for 99% of the users.
4793 Remove reference to no-longer-used HAVE_VPRINTF.
4794 Fixed BFD_DEP typo to BFD_DIR.
4796 Fix cast in arg to bfd_h_getlong.
4797 Make char *prefix be const.
4798 Fix how certain range types are mapped into builtin unsigned int types.
4800 Remove 2 #includes. They cause errors (on Sony, at least),
4801 and aren't needed (they wern't in earlier versions).
4803 print_address_symbolic should never demangle labels
4804 (since it prints *assembler-level* labels).
4806 [This was superseded by the change to printcmd below.]
4809 Add some "volatile" return types to avoid warnings.
4810 If MISSING_VPRINTF add vprintf function and not just macro
4811 (since vprintf is used in printcmd.c).
4813 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4814 (The latter isn't grokked by some PCC-based compilers.)
4816 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4818 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4819 * nindy-share/coffstrip.c
4820 Added some forward declarations (otherwise, gcc complains
4821 about implicit extern redefined as static).
4823 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4825 Changes inspired by Per Bothner:
4826 * printcmd.c (print_address_symbolic): Take additional parameter
4827 specifying whether to demangle.
4828 (print_address): Pass in asm_demangle to control demangling.
4829 (print_address_demangle): New fn, takes explicit arg to control
4831 * utils.c: Add new vars demangle and asm_demangle, and let them
4833 (fputs_demangled): If !demangle, just print the argument.
4834 (fprint_symbol): If !demangle, just print raw symbol.
4835 * valprint.c (val_print): Call print_address_demangle rather than
4836 print_address, to cause demangling to depend on the global
4837 rather than assembler-level demangling setting.
4838 * WHATS.NEW, gdb.texinfo: Document.
4840 * main.c (show_command): Show all settings if no arg.
4841 (initialize_main): Make "info set" the same as naked "show".
4842 * command.c (cmd_show_list): Handle prefix commands in the
4843 list, and print the name of the setting as well as its English
4844 description and value.
4846 Allow gdb functions to specify where a line should wrap if it
4847 exceeds the size of a terminal line. Use it to make the output
4849 * utils.c (set_screen_width_command): New fn, mallocs a buffer
4850 of the right size when screen width changes.
4851 (set_screensize_command, screensize_info): Remove #if 0'd fns.
4852 (wrap_here): New fn, indicates a point in the output where we
4853 should wrap the line rather than just letting it overflow at a
4855 (fputs_filtered): Implement wrapping.
4856 (n_spaces): New fn, returns a pointer to N spaces.
4857 (print_spaces_filtered): Use n_spaces.
4858 * defs.h (n_spaces): Declare.
4859 * stack.c (print_frame_info): Wrap with 4-space indent after
4860 fn name and before filename and line number.
4861 * printcmd.c (print_frame_args): Wrap with 4-space indent
4862 before each argument name is printed.
4863 * valprint.c (value_print): Wrap with no indentation before
4865 (val_print_fields): Wrap with indentation relative to nesting
4866 level before each field name.
4867 (val_print): Wrap with nesting indentation before array elements.
4868 * command.c (do_setshow_command): Avoid extra newlines,
4869 wrap with 4-space indent around values printed, end with period.
4870 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
4872 * breakpoint.c (breakpoint_1): Implement addressprint for
4873 "info breakpoints" display. Change file name and line number
4874 format to " at file:nnn" rather than " (file line nnn)".
4875 * gdb.texinfo: Document.
4878 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4880 Frozen for gdb-3.92.6 release.
4882 README, WHATS.NEW: Update for 3.92.6 release.
4884 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
4885 coffread.o from configs since it is now built by default.
4886 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
4887 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
4888 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
4889 from configs since it is now built by default.
4891 Makefile.dist: Update for release 3.92.6. Handle files that
4892 have been moved to ../include, ../getopt, or ../bfd. Add
4893 saber.suppress and tests directory. Add config.status to
4894 the release (it will say "none").
4896 coredep.c: Minor formatting fixes.
4898 These changes were made in early December but only checked in now:
4899 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
4900 nindy-share/nindy.c: lint
4901 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
4902 register values coming back from the target; we store values
4903 in target byte order everywhere.
4905 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
4907 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
4909 * valprint.c (cplus_val_print, val_print_fields): New functions,
4910 which print C++ objects. They conspire to avoid printing a
4911 virtual base class more than once, following all the twists and
4912 turns of C++ virtual base rules.
4913 (val_print): Call the above rather than do it by hand.
4915 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
4916 symbol file, not for added files like shared libs. This really
4917 needs to be generalized to a timestamp per file.
4919 * core.c (cleanup_core): Avoid coredump if no core file.
4921 * config.gdb: Accept -host or -target in place of +host or
4924 * coffread.c (find_linenos): Avoid desupported BFD interface
4925 to line numbers. We still read them manually rather than using
4926 BFD's "generic" features.
4928 * gdbrc.tex, threecol.tex: Add GDB reference card and its
4930 Makefile.dist: Add refcard to OTHERS list for creating tar files.
4932 * Makefile.dist: Eliminate use of $< in explicit targets.
4934 * readline/Makefile: Use $< rather than $*.c, which does not
4935 include the VPATH in GNU Make.
4937 * tconfig/i960-bout, tconfig/i960-coff: These are identical
4938 copies of tconfig/i960, added for global configuration
4939 compatability. All i960 versions can read both coff and b.out.
4941 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
4942 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
4945 * TODO: Think of more things to do.
4947 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
4949 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
4950 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
4951 64-bit float conversion.
4953 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
4954 equivalent to sun?os4 so global config works.
4956 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
4958 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
4960 * main.c: Only declare linesize once; declare pagesize not at
4961 all, since it is never used.
4962 (main): Clear newly allocated line before it is used.
4964 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
4966 Further stabilization for the Intel 960.
4968 * Makefile.dist: Parameterize the location of the "include"
4969 and "bfd" directories, as well as "getopt". Add symfile.c.
4970 Link in both dbxread and coffread. Fix up "make depend" to
4971 rewack the locations of include, bfd, and getopt in its output.
4973 * README: Document moving include files, improve some of
4976 * coffread.c: Move common code out to symfile.c. Change
4977 symbol_file_command style interface to use new *_symfile_init
4978 and *_symfile_read interface under BFD. Use BFD internal
4979 info to locate line table, symbols, etc.
4981 * core.c (core_fetch_registers): Rename to get_core_registers
4982 to avoid confusion with fetch_core_registers.
4983 (register_addr): Move to coredep.c, which is already machine
4984 dependent. This leaves core.c pretty clean of dependencies.
4986 * coredep.c (register_addr): Accept this routine from core.c.
4988 * dbxread.c: Move common code (with coffread.c, etc) into new
4989 symfile.c. Each psymtab now contains a pointer to the
4990 format-dependent function that knows how to read it in. Make
4992 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
4993 (process_one_symbol): Add code to complain about a "compiler bug
4994 we muzzle here", if we actually see it.
4996 * eval.c (evaluate_subexp): Insert missing "break" statements
4997 in code that determines whether a variable is an lvalue in
4998 memory, register, or whatever. I detected this via a compiler
4999 bug in which it *almost* mashed out the whole switch statement.
5001 * gdb-int.texinfo: Add minor sections on configuring gdb for
5002 release, and about the README file.
5004 * infcmd.c (registers_info): Fix formatting somewhat. Still
5005 not as pretty as before, but it handles byte swapping.
5007 * remote-nindy.c: If data cache routines are interrupted while
5008 waiting for the remote end, be sure that any uninitialized cache
5009 blocks are on the free list, not on the valid list!
5011 * symfile.h: Flesh out this header file with all the various
5012 routines and variables that have been merged in from dbxread.c
5013 coffread.c, and symtab.c to symfile.c.
5015 * symfile.c: New file, containing code common to dbxread.c,
5016 coffread.c, and some code from symtab.c. All generic code for
5017 reading symbol files should be in here now.
5018 (unrecord_misc_function): Remove unused function.
5020 * symtab.h: Remove file-reading things to symfile.h.
5022 * symtab.c: Remove file-reading things to symfile.c.
5024 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
5025 to decode i960 fault types.
5027 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
5028 target.c: Change type of the "resume" function from int to void,
5029 since its result was never used.
5031 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
5033 * main.c: Replace "stupid" with "caution"; you now "set caution
5036 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
5038 * infcmd.c (do_registers_info): Call val_print to deal with the
5039 byte order of the registers being printed. FIXME, this makes
5040 the formatting of the output uglier.
5042 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
5043 defined, call it for signals the debugger doesn't itself use.
5044 The i960 uses this for more detailed fault information.
5046 * remote.c (remote_open): If arg is null, print help rather than
5049 * sparc-xdep.c (register_valid): Avoid declaring size, since
5050 various modules will think of various sizes depending on the
5051 architecture of their tm-file. FIXME, we need protection against
5052 actually entering one of those modules, which would clobber
5053 storage if not for the target architecture compiled into gdb.
5055 * stack.c (up_command, down_command): Always print the frame
5057 (up_silently_command, down_silently_command): New commands
5060 * i960-pinsn.c (reg), i960-tdep.c: Lint.
5062 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
5063 more parameters than it used to.
5065 * findvar.c (registers): Increase slop to 256 bytes, which should
5066 protect us against even most RISC machines with large register
5068 (locate_var_value): Move declaration inside related ifdef.
5070 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
5071 throughout, to avoid throwing away buffered input from the board.
5072 (nindy_wait): Supply_register takes addr_of_value, not value.
5073 (i960_print_fault): Renamed from i80960_fault.
5074 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
5075 (nindy_store_registers): Avoid regs_changed stuff, just stuff
5077 (nindy_create_inferior): Don't bother to write PC_REGNUM since
5078 we can set the PC in the call to proceed(). Unpush nindy_ops
5079 before pushing it on top, to avoid message to user. Eliminate
5080 commentary from Unix machines that just misleads here.
5081 (reset_command): Fix error message to suggest target command.
5083 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
5085 Release 3.92.5 as frozen.
5087 Stabilize the merged release...with help from lint, Saber C,
5090 Everywhere: Add include files needed to declare return types
5091 of functions called.
5093 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
5095 * breakpoint.h: Add undeclared breakpoint functions, and some
5096 functions for display handling since I couldn't think of a better
5099 * breakpoint.c (insert_breakpoints): Make code for disabling
5100 shared library bkpts more likely to work. It's used when we
5101 rerun a program and stop before the shared library has been
5103 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
5104 cast from pointer, so it squeezes through catch_errors.
5105 (bpstat_stop_status): Fix logic broken some time ago. We now
5106 always create a bpstat if the stop address matches a breakpoint,
5107 even if we don't stop there -- just like the old code used to do
5108 before I got my fingers into it (sigh).
5109 (breakpoint_1): Print "ignore count" after "stop only if"
5110 condition, since that's how it actually works.
5111 (mention): Handle watchpoints as well as breakpoints.
5112 (watch_command): use set_raw_breakpoint and mention to do most
5113 of the work (and initialize all the fields!). Only pass one
5114 arg to parse_c_expression, since that's all it takes.
5116 * command.c (not_just_help_class_command): Rename arg to args
5117 since we ignore "unused argument" warnings on vars named "args".
5118 inflow.c (child_terminal_info): ditto.
5119 infptrace.c (kill_inferior): ditto
5120 main.c (catch_errors, version_info, quit_command, pwd_command,
5121 source_command, dump_me_command, editing_info,
5122 set_history_size_command, set_history, show_history,
5124 stack.c (locals_info): ditto
5125 target.c (target_files_info): ditto
5126 valprint.c (set_input_radix, set_output_radix): ditto
5128 * core.c: Remove old variables for handling core and exec file
5129 sections (data_start, data_end, stack_start, stack_end,
5130 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
5131 text_end, exec_data_start, exec_data_end, text_offset,
5132 exec_data_offset, data_offset, stack_offset). They're
5133 superseded the more general build_section_table and
5135 (get_exec_file): Mention the `file' command.
5136 (read_memory_check): Rename to memory_error, and only call it
5137 in the case of an actual error.
5138 (read_memory, write_memory): call memory_error.
5139 (core_fetch_registers): Register section name is ".reg".
5141 coredep.c: Remove a bunch of crud now that all this file does
5142 is pull the registers out of a core file.
5143 (fetch_core_registers): Rewrite to actually work, I hope.
5145 dbxread.c: Use a.out.gnu.h, not system a.out, now.
5146 Replace index() with strchr(). Remove all the pre-BFD macro
5147 definitions for accessing the symbol file.
5148 (struct dbx_symfile_info): Encapsulate the information that
5149 dbx_symfile_init needs to pass to dbx_symfile_read in this
5152 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
5153 dbx_symfile_discard): Rearrange symbol file reading to divide
5154 the format-specific part from the format-independent part,
5155 leaving the format-independent part such as file name expansion
5156 and opening in symtab.c. This replaces
5157 partial_symbol_file_open and partial_symbol_file_read.
5158 Symbol_file_read, add_file, add_file_target_command,
5159 add_file_addr_command move to symtab.c. Pass an explicit
5160 "mainline" flag for when reading the main symbol table, rather
5161 than relying on the offset address to be zero or nonzero.
5163 (dbx_symfile_read): Don't allow void *'s to be printed as
5165 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
5166 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
5167 macro" debug version really work.
5168 (read_dbx_symtab): Remove unref'd parameter inclink.
5169 Avoid swapping N_SLINE symbols, for speed.
5170 Merge N_TEXT!N_EXT case with the other external symbol
5171 definitions' case. Add comments.
5172 (start_psymtab): Allocate the symfile name in the psymtab on
5173 the psymbol_obstack, rather than using the caller's storage.
5174 (end_psymtab): Only allocate a dependencies list if there are
5176 (psymtab_to_symtab_2): Use BFD when reopening file to read
5177 its symbols for real.
5178 (read_struct_type): Add FIXME comments where it needs work
5180 (read_huge_number): Add FIXME about overflows.
5181 (read_range_type): Add FIXME about comparing a long to 1<<32.
5183 * coffread.c: Minor changes to move things closer to the new
5184 regime with symtab.c and dbxread.c Major work is still needed
5187 * exec.c (exec_file_command): Remove old variables (see core.c
5189 (xfer_memory): If memory transfer is right at the end of a
5190 section, don't lose.
5192 * findvar.c (get_saved_register): If value is in a real
5193 register, LVAL is lval_register, not lval_memory.
5195 frame.h: Declare print_sel_frame and record_selected_frame.
5197 gdb-int.texinfo: New file, for GDB internals documentation.
5198 Very simple, unformatted doc of cleanups is there for now.
5200 gdbcore.h: Remove obsolete variables that described a.out
5201 section addresses and offsets. (See core.c above.)
5202 Declare fetch_core_registers and registers_fetched.
5204 getopt.c: Declare char *alloca(); even on SPARC.
5206 infcmd.c (run_command): Call target_kill rather than
5208 (step_command, next_command, stepi_command, nexti_command):
5209 Declare from_tty parameter even though we don't use it.
5210 (run_stack_dummy): argument BUFFER is a char array, not
5211 a pointer to REGISTER_TYPE.
5212 (finish_command): using_struct_return needed a value *,
5213 not a struct symbol *.
5215 * infptrace.c (child_xfer_memory): To avoid dependency on
5216 where sections are in memory, try PT_WRITE_D and if that fails,
5217 try PT_WRITE_I. Most Unixes don't care which you use.
5219 * infrun.c (step_resume_break_shadow): Change to array to
5220 match other breakpoint shadow storage.
5221 (clear_proceed_status): Pass address of bpstat to
5222 bpstat_clear, not the bpstat itself.
5223 (child_create_inferior): FIXME comment about if the child
5225 (start_inferior): Remove old function.
5226 (child_open): Use target_kill rather than kill_inferior.
5227 (wait_for_inferior): Ditto.
5228 (insert_step_breakpoint, remote_step_breakpoint): Use
5229 new step_resume_break_shadow.
5231 * inftarg.c (child_wait): If all child processes die,
5232 pretend that the one being waited for exited with signal 42.
5234 * main.c (command_line_input): When scanning for comments,
5235 don't coredump on unclosed quotes.
5236 (quit_command): Use target_kill rther than kill_inferior.
5237 (_initialize_main): Rename class_user from "user" to
5240 * printcmd.c (print_command_1): Initialize "fmt" if no format
5241 is specified by the user.
5242 (print_frame_args): Only add to args_printed if we are
5243 actually fetching args from the stack (avoiding undefined
5245 (_initialize_printcmd): Remove bogus \{ from string.
5247 * remote-eb.c (eb_open): Avoid coredump on no argument.
5249 * remote-nindy.c: Bring out of Intel environment into new
5250 target environment. Remove all conditional compilation on
5251 I80960. Massive hacking throughout.
5252 (nindy_xfer_inferior_memory): New routine stolen from
5254 (nindy_create_inferior): New routine pieced together, probably
5255 not quite working yet.
5256 (nindy_ops): New target_ops struct for nindy.
5258 * remote-vx.c: Use write_memory rather than target_write_memory
5259 to get error checking.
5260 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5262 (vx_create_inferior): Use target_terminal_ours...
5264 * signame.c (_initialize_signame): Always initialize, since
5265 we need the table for things other than psignal.
5267 * solib.c (solib_add): Use symbol_file_add, not add_file.
5268 (solib_address): Return boolean result rather than struct
5269 pointer which nobody else knows the type of.
5271 * sparc-tdep.c, valops.c: Use write_memory rather than
5272 target_write_memory, to get error checking.
5274 * stack.c (locals_info, catch_info, args_info,
5275 get_selected_block, frame_command, up_command): Use
5276 target_has_stack, rather than have_inferior_p or
5279 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5281 * symfile.h: New file, defining the interface between the
5282 generic and object-file-specific symbol reading code.
5284 * symtab.c: Move generic symbol-reading interface to symtab.c,
5285 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5286 table to map BFD targets to symbol-reading modules in GDB.
5287 Change index to strchr.
5288 (lookup_struct_elt_type): Use error() rather than hand-made
5289 simulations thereof.
5290 (lookup_partial_symbol): Speedup slightly when length == 0.
5291 (symbol_file_add): New function.
5292 (symbol_file_command): Call it.
5293 (symfile_open, symfile_init): New function.
5294 (add_file_target_command, add_file_addr_command): moved from
5297 * target.c (target_command): use target_kill.
5299 * target.h (target_files_info): Don't declare, never called
5302 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5303 files to determine stack end address.
5305 * valarith.c (value_x_binop, value_x_unop): Change error message
5306 to be more useful. Pass proper argument to value_struct_elt.
5308 * valops.c (value_assign): FIXME comment that long long
5309 bitfields will break here.
5311 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5312 Update `make saber_gdb' to work better.
5314 * TODO: A woman's work is never done.
5316 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5317 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5318 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5319 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5320 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5321 valops.c, valprint.c, exec.c: Lint.
5324 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5326 Continuing Intel 960 port merge of GDB.
5328 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5329 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5330 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5331 Wack over "make depend" so it handles files in subdirectories
5332 vx-share, nindy-share, bfd, and in the current directory.
5334 * blockframe.c (get_prev_frame_info): Remove fatal error
5335 if stack not defined.
5337 * core.c (core_open, core_detach): New functions that handle
5338 the old "core-file" command as "target core" and "detach" instead.
5339 (core_file_command): Call them.
5340 (core_xfer_memory): Use common routine xfer_memory.
5342 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5343 dbxread now uses bfd for everything but symbol reading itself.
5344 BFD internals are used to drag out the relevant file offsets.
5345 (partial_symbol_file_open): Change args all around for BFD.
5347 * symtab.c: Rename "value" to "val" everywhere, so we can
5349 (symbol_file_command): New command, moved from dbxread.c
5350 and coffread.c. It uses BFD to read the file, then vectors
5351 based on its type, to dbx or coff symbol readers.
5352 * symtab.h: Extern a few vars for symbol_file_command.
5354 * target.h: Breakpoint takes a char * save area, not a char **.
5356 * valprint.c (val_print): When unpacking bitfields, offset
5357 the address in gdb of the value, if it is declared with a shorter
5358 type. Remove the last "runtime kludge test" of host byte order.
5360 * utils.c: Remove old my_bfd_read routine.
5362 * stack.c (frame_info): Use target_has_stack. Print program counter
5363 register's actual name rather than "pc", since it's called the
5364 "ip" (instruction pointer) on the i960 (sigh).
5366 * target.c (target_command): Add command for selecting a target
5367 type and calling its open routine. This is used for initiating
5368 communication with a particular target, in a generic way.
5370 * tm-i960.h: Update for modern gdb. Remove semicolons from
5371 various macros. Handle reading struct return convention, and
5372 error-out attempts to return structs with the "return" command.
5373 Be sure gdb doesn't think we know how to call functions in the
5376 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5377 to i960_xxx in lower case.
5378 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5379 not being defined yet.
5381 * remote.c (remote_open): Call start_remote to initialize
5382 wait_for_inferior during open.
5383 (remote_xfer_inferior_memory): Return length written rather
5386 * remote-vx.c (target_command -> vx_open): Use new generic
5388 * remote-eb.c, inftarg.c, exec.c: ditto.
5390 * infrun.c: Fix comments.
5391 (attach_program -> child_open): Use new generic target command.
5392 (wait_for_inferior): Clear saved register values before target_wait,
5393 so target_wait can set some of them if convenient.
5395 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5396 Return success indicator, not void.
5397 (child_xfer_memory): Avoid fetching initial word if we'll
5398 overwrite it anyway.
5400 * infcmd.c (attach_command): Use new generic target open routine.
5401 (_initialize_infcmd): Update doc on attach and detach commands.
5402 (do_registers_info): Merge in a byte-order problem as a FIXME
5405 * findvar.c (find_saved_register): Avoid problem in current frame.
5406 (read_relative_register): Ditto.
5407 (write_register): Convert byte order on the way out.
5409 * exec.c (file_command): Add.
5410 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5411 (xfer_memory): Common function between core_xfer_memory and
5413 (exec_xfer_memory): Use it.
5415 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5417 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5418 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5419 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5421 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5423 Merge Intel 960 port of gdb, continuing...
5425 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5426 symbol_file_command): Pass from_tty arg to hush 'em up.
5428 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5429 Add magic numbers for 960 COFF format.
5431 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5433 Merge Intel 960 port of gdb, from Intel "1.2" release.

5446 Tue May 29 12:54:49 PDT 1990
5447 Added variable baud rate (-b switch).
5448 Source code reorganization.
5450 Thu Apr 26 11:09:55 PDT 1990
5451 More cleanup of batch mode; specifically, execute "-s", "-e", and
5452 "-se" switches as soon as they are encountered on the invocation line.
5454 Fri Apr 20 13:47:15 PDT 1990
5457 Thu Apr 19 09:54:28 PDT 1990
5458 Add 'reset' command.
5460 Wed Apr 18 09:48:07 PDT 1990
5461 After opening remote tty, wait for 1 second to go by without input
5462 from it before trying to talk to NINDY (fixes problems with the
5463 Heurikon HK80/V960E).
5465 Mon Apr 4 16:33:05 PDT 1990
5466 Some output was not being suppressed in 'batch' mode.
5468 Thu Mar 22 15:31:11 PST 1990
5469 Ask user if old symbol table should be deleted when new file is
5472 Allow user to run a program downloaded before gdb960 was brought up.
5474 Correct "exec-file" help message for i80960 context.
5476 Correct bug in calculating user space address: could occasionally
5477 corrupt user program.
5479 Make sure to zero low-order bits in rip's because of bug in 960CA
5480 A-step part: could cause operation faults when "next"ing across
5483 Correct bug that made it impossible to get source line numbers for
5484 code loaded at addresses higher than 0x7fffffff.
5486 Wed Jan 10 12:43:22 PST 1990
5487 Open remote tty for exclusive use.
5489 Fri Jan 5 12:14:42 PST 1990
5490 Correct disassembly (CA manual was right after all):
5491 opcode for sysctl is 0x659
5493 Mon Oct 23 12:03:04 PDT 1989
5494 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5496 Mon Oct 16 14:15:09 PDT 1989
5497 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5499 Mon Oct 2 15:56:31 PDT 1989
5501 Added 960CA disassembly support.
5503 To simplify maintenance:
5504 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5506 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5507 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5508 - made disassembly interface identical to that in gdmp960.
5512 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5514 * target.h: Allow targets to stack. Add target_has_memory,
5515 _registers, etc. Restructure memory access and "info files"
5516 to walk the target stack.
5517 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5518 target.c: Change tables to match target.h.
5519 * inflow.c (child_mourn_inferior): pop child_ops.
5520 (generic_mourn_inferior): Use new has_stack flag.
5521 * infptrace.c (child_xfer_memory): New memory regime.
5522 * inftarg.c (child_files_info): New "info files" regime.
5523 * remote-eb.c: New memory regime, new info files.
5524 * remote-vx.c: New memory regime, new info files. Now use
5525 separate targets for VxWorks attachment to machine, and
5526 actually running a process under VxWorks, since one has
5527 stack & execution & regs and the other doesn't.
5528 * remote.c: New memory regime, new info files.
5529 * sparc-xdep.c (fetch_core-registers): New memory regime.
5530 * target.c: New routines and support for stacked targets,
5531 new memory regime, new info files regime.
5534 Generalize section handling for an arbitrary number of sections,
5535 including use of the new BFD (binary file) library.
5536 * gdbcore.h: Add struct section_table.
5537 * exec.c (build_section_table): Iterate all sections and
5538 record what gdb needs to know about them.
5539 (exec_command): Use it.
5540 (exec_xfer_memory): Use the table.
5541 (exec_files_info): Print the table.
5542 * core.c (core_file_command, core_xfer_memory, core_files_info):
5544 * source.c (find_source_lines): Use bfd_get_mtime.
5545 * dbxread.c: Quick changes to make it compile with new BFD.
5546 * utils.c (error): Avoid using bfd_error in generic routines.
5548 * core.c (core_fetch_registers): Get from the ".regs" section of
5550 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5552 * inferior.h (attach_flag): Export.
5553 * infcmd.c (run_command): use new target_create_inferior.
5554 * infrun.c (child_create_inferior): Don't return result.
5555 * Makefile.dist (VERSION): 3.91.4.
5557 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5559 * breakpoint.c (bpstat_num): Handle breakpoints which have
5560 since been deleted, such as temporary breakpoints.
5561 infcmd.c (program_info): ditto.
5563 * core.c (core_file_command): Display the frame where the core
5568 * remote-vx.c (target_command): Merge in target command from
5569 targ-vx.c. A few other cleanups.
5571 * TODO, Projects: Lots more stuff to do...
5573 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5575 Massive changes to wall off the remote-debugging interface
5576 behind a function vector. The port to handle VxWorks targets
5577 is also part of this.
5579 All files: Replace references to renamed functions,
5580 remove references to remote_debugging, remove references to
5581 have_include_file, have_core_file in favor of target_has_stack,
5582 target_has_memory, etc.
5584 * Modularize the breakpoint interface.
5585 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5586 a breakpoint instruction.
5587 breakpoint.c: struct breakpoint's shadow_contents now sized as
5589 (insert_breakpoints): Vector to target to install breakpoints.
5590 (remove_breakpoints): Vector to target here too.
5591 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5592 sparc-tdep.c (single_step): Use new breakpoint interface for
5593 the single-step breakpoints.
5594 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5595 New file, contains routines to insert and remove breakpoints by
5596 reading out the old contents and later replacing them. This is
5597 how ptrace breakpoints work, and many remote systems as well.
5599 * tm-vxworks68.h: New config file, overrides a few things for
5600 Wind River's preferences.
5602 * target.h: New file, for transfer vector used to talk to the
5603 inferior (child, attached, core, exec, remote, etc). All accesses
5604 to the thing being debugged should come through these vectors.
5605 target.c: New file, routines to handle transfer vector.
5606 (various files): Add transfer vectors XXX_ops for the various
5607 targets and pseudo-targets (core files, etc) we support.
5609 * breakpoint.c (bpstat_stop_status): Further explorations of
5610 watchpoints and why things don't work all the time.
5611 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5613 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5614 the local gdbinit if it doesn't already have it.
5616 * core.c (core_ops): add and install.
5617 Allow core debugging without exec file.
5619 * dbxread.c (free_and_init_header_files): Merge two fns.
5620 (end_symtab): Free named symbol table when a new version comes in.
5621 (read_dbx_symtab): Relocate all kinds of symbols with base
5622 address. First step toward handling different text, data, bss
5624 (add_file_addr_command): Renamed add_file_command.
5625 (add_file_command): Vector to remote handler.
5626 Add "load" as an alias for "add-file" command.
5628 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5629 non-returning functions.
5631 * exec.c: Add exec_ops, and push it as a target when an exec
5634 * infcmd.c (run_command): Pass executable file name and arg list
5635 separately when starting an inferior. Permit "run" when no exec
5636 file is specified, for VxWorks.
5637 (detach_command): Move to child_detach in inftarg.c.
5639 * inftarg.c: New file. Unix-child-specific routines, and the
5640 child_ops structure.
5642 * inferior.h (registers): Export "registers" as the way for
5643 target dependent register handlers to find gdb's local copy of
5644 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5645 since it is now used by places that want wait_for_inferior to
5646 handle the grunge but want to see every trap from the inferior.
5648 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5649 Eliminate remote_debugging hooks in terminal handling.
5651 * infrun.c: Replace start_inferior with child_create_inferior.
5652 Move all the hair of Unix shells and ptrace idiosyncracies into
5653 child_create_inferior, so remote handlers don't have to deal.
5654 Remove running_in_shell. Rename stop_after_attach to
5655 stop_soon_quietly, and use it in a few other places where we want
5656 to just call wait_for_inferior and get control back on the first
5657 trap. trap_expected now never takes a value > 1.
5658 (init_wait_for_inferior): Initialize static vars when a new
5661 main.c (gdbinit): Add new hook for .gdbinit file name, let
5662 it be overridden by config files as GDBINIT_FILENAME.
5663 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5664 Both of these are used for VxWorks gdb.
5666 mcheck.c: rename include file "gmalloc.c" to avoid problems
5667 with system include file "malloc.c".
5669 param-no-tm.h: New include file, same as param.h but does not
5670 include the default "tm.h" file. This is used in files where
5671 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5673 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5675 remote-vx.c: New file, VxWorks remote debugging support. Uses
5676 RPC routines that are shared with the target system, in directory
5679 remote.c: Vectorize remote interface.
5681 source.c: Globalize source_path, and make an alias "l" for "list"
5682 since we now have the "load" command.
5684 sparc-xdep.c: Use new param-no-tm.h.
5686 symmisc.c (free_named_symtab): Add new function from Wind River.
5687 However, ifdef it out for now while we think about what it should
5690 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5692 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5693 non-Unix-children handle this with their own code in the target
5696 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5697 source and target lists. Add vx-share to default list of include
5698 directories. Add new files to src and target lists: mem-break,
5699 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5700 ${srcdir} versions of munch and createtags are used.
5702 * valops.c (find_function_addr): Split out of call_function.
5703 (call_function_by_hand): Rename call_function; this function
5704 calls functions in the target by laboriously patching the target
5705 word-by-word with the right stack, args, regs, etc.
5708 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5710 Handle AMD 29000 a bit better.
5712 * remote-eb.c (readchar): Mask received char log to make it readable.
5713 (remote_start): Pass arguments down to executing program.
5714 Make startaddr unsigned.
5715 infrun.c (start_inferior): Accept args, pass them to
5717 infcmd.c (run_command): Pass args down to start_inferior.
5719 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5720 the target object file format.
5721 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5723 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5724 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5726 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5728 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5729 * TODO: We did a few things, we have more to do though.
5731 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
5732 * inflow.c (inferior_died): Clear deferred stores.
5734 * Debug problems with dummy frames and calls to the inferior.
5735 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5736 * sparc-tdep.c (do_restore_insn): Simplify.
5737 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5738 (sparc_push_dummy_frame): Simplify and fix what we push.
5739 (sparc_pop_frame): Slightly more hair here, deciding whether
5740 we are restoring a saved PC or returning to a return address in %i7.
5741 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5743 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5744 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5745 * obstack.h (chunkfun): ditto.
5746 * defs.h (xmalloc, xrealloc): ditto
5748 * utils.c (quit): Grab the terminal from the child if necessary.
5750 * inflow.c (term_status_command): Rename to term_info, change
5753 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5754 (is_delayed_branch): Speed up.
5755 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5756 Still missing some float ops, and needs testing.
5758 * Support for input and output radixes other than base 10
5759 * defs.h (input_radix, output_radix): Declare.
5760 * expread.y (yyparse, parse_number): Handle changes of input
5761 radix, and ambiguous names-or-numbers in radixes >10.
5762 * printcmd.c (print_scalar_formatted): Print formatted hex
5763 numbers in varying column widths.
5764 * valprint.c (val_print): Use output_format to print scalar ints.
5765 (set_input_radix, set_output_radix, set_radix): Create.
5766 (set_output_radix): Set output_format from output_radix.
5767 (_initialize_valprint): add `set radix' but leave the others off.
5769 * main.c (execute_command): Let stupid questions be turned off.
5770 (_initialize_main): Handle "set stupidity", etc.
5772 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5773 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5775 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5777 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5778 bfd stuff is still screwed up, but with some manual work, it
5781 * breakpoint.c (bpstat_do_actions): Start over if a command
5782 proceeds the inferior, since the inferior will have stopped and
5783 will need to have its new stop-actions taken care of.
5785 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5786 compiler fits, simplify it.
5788 * gdb.texinfo (directory command): Doc new dir command.
5789 source.c (directory_command): "dir" now puts things on the front
5790 of the path, moves dups up front, and handles multiple names
5791 on the command line, inserting each one in order. It also
5792 blows away cached line and full_filename info.
5794 * stack.c (backtrace_command): Skip "more stack frames follow"
5797 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5798 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5799 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5800 The only odd one was Gould NP1, which had defined vprintf to
5803 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5804 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5805 variable, inspect_it.
5806 valprint.c (print_string, val_print): Use the global inspect_it
5807 to indicate whether to print in Epoch style or normal style.
5809 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5811 * printcmd.c (call_command): add an alias for the "print" command
5812 which runs expressions and doesn't print the result if void.
5813 (print_command_1): implement it.
5815 * command.c: Remove #if 0'd code. Initialize all the fields
5816 in add_cmd (). Rename do_nothing_command to
5817 not_just_help_class_command, and make it externally visible.
5818 command.h: add user_commands to struct.
5819 * main.c (define_command): Don't overload c->function with a char
5820 string as well as a function pointer.
5822 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5823 calling convention of value_struct_elt () that got dropped in
5826 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5827 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5829 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5831 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5832 until a good time (e.g. when we are about to run the child),
5833 saving ptrace calls.
5834 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5835 * tm-sparc.h: define DO_DEFERRED_STORES.
5837 * sparc-xdep.c (store_inferior_registers): when storing float
5838 registers, don't store stack regs too. When storing the SP,
5839 however, DO store the stack regs too. This fixes a bug in which
5840 the dummy frame is not recognized when a call_function finishes,
5841 because its frame pointer (in the stack regs) was never
5843 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5844 even though we don't know how to read them from an inferior.
5845 valops.c (call_function): Comment about storing SP.
5847 * infrun.c (save_inferior_status): Save away the original bpstat
5848 chain so it can be restored later. Install the copied version for
5849 use by whoever saved the status. It will be blow away by
5850 restore_inferior_status, and the original chain restored. This is
5851 important for people who have pointers into the original.
5853 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
5854 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
5855 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
5858 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
5860 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
5861 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
5862 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
5864 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
5866 * Merge Mike Tiemann's multiple inheritance changes from Sun.
5867 Store the baseclasses in a type struct starting from array element
5868 0 rather than from the unusual array element 1.
5870 dbxread.c: the above.
5871 (virtual_context): Add
5872 Read new debug information about which virtual function table
5873 a virtual function is from, and store it in fn_field.fcontext.
5875 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
5876 TYPE_FN_FIELD_STATIC_P.
5878 symtab.c: the above.
5879 valops.c: the above. Handle pointer casts of object *'s.
5880 (search_struct_method): Add.
5881 (value_struct_elt): First arg is now a pointer to a value, and is
5884 valprint.c: the above.
5885 values.c (value_virtual_fn_field): Add type arg. Handle
5886 offsetting to the proper object when calling virtual fns.
5888 (baseclass_addr): Add valuep arg.
5890 * README: Document the current state of BFD config (missing).
5891 * TODO, ChangeLog, Makefile.dist: Roll version.
5892 * WHATS.NEW: Add summary of changes since 3.5.
5894 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
5896 * dbxread.c (read_struct_type): Clear bit vectors whenever
5898 symtab.c (B_CLRALL): define.
5900 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
5901 using == rather than =. Huh... This fixes the dreaded problem
5902 wherein builtin_type_int becomes TYPE_CODE_FLT.
5904 * core.c (info_files): Show the inferior pid.
5906 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
5907 already knows how to look in the source directory.
5909 * Remove psymtab hair from many places. Remove duplicated code
5910 for searching symbol tables. Hide psymtabs from most places.
5911 Make it fast to get from a psymtab to its symtab.
5913 blockframe.c (blockvector_for_pc): Remove psymtab hair.
5914 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5915 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
5916 dbxread.c: export psymtab_to_symtab, make it work if called N times.
5917 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
5918 new symtab completely. New psymtabs get symtab pointer
5919 initialized to zero. Remove MI warning printf.
5920 symtab.h: Comments. Add psymtab to symtab pointer.
5921 (PSYMTAB_TO_SYMTAB): New macro.
5922 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
5923 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
5925 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
5927 (print_frame_info): Avoid special-casing symbols that have not yet
5930 * source.c (open_source_file): Quick path if we have already
5931 located the source file by its full name.
5933 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
5934 find_pc_psymtab. When a name is found in the misc function
5935 vector, search the symbol table for its mangled name, not the
5936 name that the user typed.
5938 * bfd.h: Fix missing comment terminators, make #endifs match.
5940 * valarith.c (value_less): Handle unsigned int comparisons.
5941 Add FIXME about pointer compares, which assume host and target
5942 pointers are the same.
5944 * command.c (do_nothing_command): lint
5945 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
5946 fix comments on debug symbol format for visibility. Actually set
5947 visibility of symbols.
5948 main.c (echo_command): lint; use <readline/history.h>.
5949 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
5950 obstack.h (_obstack_blank): Rearrange pointer math to avoid
5951 pointing past end of allocated memory; saber complains.
5952 obstack.h: Declare the external functions that we use.
5953 valarith.h: use <string.h>
5954 solib.c (solib_add): lint.
5956 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
5958 * main.c (initialize_main): Default info_verbose to off, now that
5959 symbol reading is fast.
5960 (quit_command): Avoid clobbering exec_bfd while quitting.
5962 * Initial BFD (binary file diddling library) merger:
5963 coffread.c: Change AOUTHDR to struct exe_hdr.
5965 core.c: initialize initialized data at compile time.
5966 (core_file_command): Move from coredep.c, convert to bfd.
5967 (xfer_core_file): Convert to bfd.
5968 exec.c (exec_file_command): use bfd routines.
5970 mips-tdep.c: Remove exec_file_command and friends.
5973 * coredep.c: (fetch_core_registers) Convert core_file_command to
5974 fetch_core_registers.
5975 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
5977 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
5978 (my_bfd_read): More bogosity, which I don't think we call.
5979 (program_name): Remove this atrocity asap!
5981 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
5984 values.c: allocate_repeat_value was not clearing the
5985 optimized_out field.
5986 (value_static_field): minor stylistic fix (wrong macro was used).
5987 valops.c (value_struct_elt_for_address): didn't work for C++
5990 * signame.c (_initialize_signame): Initialize signal names once.
5992 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
5993 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
5994 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
5996 * remote-eb.c: Support user-settable baud rates on the serial port.
5998 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
6000 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
6002 * tconfig/sun3os4: Remove warning about native assembler,
6003 since it also occurs in the xconfig file.
6005 * findvar.c (registers): Allocate some slop after `registers'
6006 to prevent stray accesses from trashing the next variable.
6008 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
6009 on the sun-3, by changing the #ifdef from `sun3' (which is not
6010 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
6011 vars, which happened to follow `registers' in the executable.
6013 * readline/history.c (history_search): Heed gcc-2's advice
6014 and parenthesize && inside ||).
6016 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
6017 tm-29k.c: Insert FSF copyright headers.
6019 * remote-eb.c: Better comments.
6021 * Makefile.dist: Update to 3.91.6.
6022 * TODO: note PREPARE_TO_STORE problem.
6024 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
6026 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
6028 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
6030 * infrun.c (wait_for_inferior, at end): Don't set up
6031 prev_* if the inferior no longer exists.
6033 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
6034 CANNOT_EXECUTE_STACK.
6035 valops.c (call_function): Use it.
6037 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
6039 * inferior.h (PC_IN_CALL_DUMMY): New macro.
6040 infrun.c (wait_for_inferior, 2 places): Use it.
6042 * values.c (value_being_returned): Only use
6043 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
6045 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
6046 right thing for remote-eb.c.
6048 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
6049 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
6051 * blockframe.c: Put get_frame_saved_regs inside #if !defined
6052 (FRAME_FIND_SAVED_REGS).
6054 * findvar.c ({fetch,store}_registers): Check for
6055 REMOTE_{FETCH_STORE}_REGISTER macro.
6057 * findvar.c (get_saved_register): Add argument lval and
6058 change meaning of argument addr.
6059 findvar.c: Change calls to get_saved_register to reflect
6060 new calling convention.
6061 valops.c (value_assign): Use get_saved_register instead of
6062 find_saved_register.
6064 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6066 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
6067 an (uninitialized) pointer to one. Use "&" when passing it
6070 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6072 * coffread.c (getfilename): Use DGUX x_offset and x_name if
6075 * coffread.c (symbol_file_command): Put semicolon after
6077 Put safe_to_init_tdesc_context in #if defined (TDESC).
6078 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
6079 coffread.c: #include <sys/stat.h>.
6080 (read_coff_symtab): Typo: in_source_files -> in_source_file.
6081 Add missing ')' in check for "lc%" and friends. Remove
6083 Declare read_one_sym() at top of file.
6084 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
6085 MC68WRMAGIC can have the same value without causing a duplicate
6088 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
6090 * Allow a Makefile to be built without building the
6091 tm and xm file links that screw up builds in subdirectories.
6092 This is done with `config.gdb none', then you can do things
6093 like `make gdb.tar.Z'.
6094 * tconfig/none: Config file for no target system
6095 * xconfig/none: Config file for no host system
6096 * config.gdb: If no TM or XM files are called out by the
6097 host or target file, don't make links for them.
6099 * cplus-dem.c: Add documentation.
6101 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
6102 simple error, so the user's gdb doesn't crash due to some object
6103 file problem (e.g. somebody is rebuilding the file out from under
6106 * printcmd.c (print_address_symbolic): demangle the symbol.
6108 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
6109 Motorola copyrights in it. Make "make gdb.tar.Z" work.
6110 (alldeps.mak): sort and uniq all results from this; duplicates
6111 hose gdb.tar.Z link building. Remove RCS files from
6112 tconfig and xconfig. Add config files for sun386. Add
6113 a few odd files to OTHERS and HFILES.
6115 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
6117 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
6118 Roll version number to 3.91.5. Make lint work in bindir.
6120 * README: Document cross-debugging and new file structure.
6122 * blockframe.c: Lint. Include "value.h" to declare read_register.
6123 (find_pc_partial_function): remove duplicate line.
6125 * command.h: Lint. Declare error_no_arg and dont_repeat.
6127 * tm-news.h: Remove inadvertently duplicated stuff.
6129 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
6130 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
6132 * config.gdb: Allow `config.gdb host target' form. Clean
6133 up previous change that printed bogus messages when you just said
6136 * core.c: #include "command.h" for lint.
6139 * main.c: Remove some casts of enums. Lint.
6146 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
6148 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
6149 read it from memory. This will allow us to save ptrace calls
6150 eventually. Changed caller single_step too.
6152 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
6153 that we aren't going to use, saving many ptrace calls, especially
6154 when watchpointing or single stepping. Use some #define's for
6156 (store_inferior_registers): Ditto.
6157 (core_file_command): Use some #define's for constants.
6159 * tm-sparc.h: Add #define's for some register numbers, so we
6160 can eliminate the use of random constants in sparc-xdep.c.
6162 * stack.c (frame_command, print_frame_info, up_command,
6163 down_command) Remove frame_changed, since it
6164 causes a bug and doesn't seem to do anything useful. In some
6165 places it was used as a flag, in others as a stack level (?).
6167 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
6168 default is to use the portable (vprintf) version rather than the
6170 * xm-news.h (MISSING_VPRINTF): Add.
6172 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
6174 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
6176 * Remove stuff that forces -Bstatic linking of gdb, and warnings
6177 about linking debugged programs -Bstatic in the sun?os4 config
6178 files in tconfig and xconfig subdirectories.
6180 * main.c (main): Remove unreached exit(0) now that we exit
6183 * Create TODO file for online bug list. There are too many
6184 "little" bugs to keep track of on paper.
6186 * Change Projects file to refer to bug-gdb@cygnus.com
6187 rather than kingdon@ai.
6189 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6191 * Makefile.dist (VERSION): 3.91.4 now.
6193 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6194 (condense_misc_bunches): Add sanity check that misc_count is
6195 the same as the number of symbols in the bunch.
6197 * coffread.c: rename init_misc_bunches. Pass an argument
6198 to condense_misc_bunches (a zero).
6200 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6201 every time we are called; don't rely on our caller to do it.
6202 (add_file): Remove call to init_misc_bunches.
6204 * mipsread.c: Only warn, don't error, if unknown symbol types.
6205 This keeps an old gdb from falling on its face if it sees newly
6206 extended symbol info. Rename init_misc_bunches.
6208 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6210 * Merge in changes from Per Bothner for DECstations and other
6211 MIPS stuff. The rest is Bothner speaking:
6213 The next message is a merger of Alessando Forin's mips port with
6214 mine. I've tried to use my good if biased judgment to get
6215 the best of both. It *does* need testing.
6217 Some of the changes are general, *not* mips-specific.
6220 Didn't believe in little-endian bit order.
6221 There are still inconsistencies about whether flags
6222 like BITS_BIG_ENDIAN are integer (#if ...) or
6223 boolean (#ifdef ...). I tried to paper over them.
6225 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6226 Moved some misc_function code that was common to
6227 {dbx,coff,mips}read.c to symtab.c.
6228 In the process, I think I cleaned things up a bit.
6229 At the same time, moved obsavestring and obconcat to symtab.c.
6232 Removed obsolete condense_addl_misc_bunches (use
6233 condense_misc_bunches(1) instead).
6236 Needed to include <sys/dir>, at least on DECstations.
6238 valops.c, mips-tdep.c, tm-mips.h:
6239 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6240 conventions (when STACK_ALIGN is insufficient).
6241 Needed on mips, where doubles need 8-byte alignment,
6242 but ints only need 4.
6245 Removed cruft that was not being used.
6246 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6249 Print $ before register-names (I think that makes things a little
6251 Never print two instructions, even if one delays.
6252 Removed hex-disassemble set_cmd. (This is not mips-specific,
6253 so I think the argument is whether it is generally worthwhile or not.
6254 I'm inclined to think not, given how easy it is to
6255 convert between radixes in gdb.)
6258 This is basically Alessando's code.
6259 It doesn't use obstacks; I changed it to use obstacks
6260 in a few minor places where using malloc causes a
6261 memory leak. (Probably, more places could/should be changed.)
6262 I added record_misc_function where it was missing.
6263 In symbol_file_command and add_file_command, I tried
6264 to make the code consistent with more recent versions.
6265 Minor sylistic changes in parse_procedure.
6266 Make a .gdbinfo. psuedo-symbol point back to the real
6267 procedure symbol (using the isym field).
6270 This is basically from my port, but with a lot of details
6271 and a number of routines merged in from Alessando's version.
6272 I basically used my code "raw" backtrace (use heuristics
6273 from the actual code, rather than symbol table info) - though
6274 the idea is Alessandro's. I feel my code is a little cleaner
6275 here, particularly in being a little more flexible, such as being
6276 able to handle gcc-produced code (which it now can).
6277 It also doesn't do frame caching (which is not useful
6278 more recent gdb versions).
6279 I also used my code for push_/pop_dummy, more or less.
6280 I tried to incorporate AF's code for testing sigtramp
6281 while backtracing; I probably got it wrong.
6282 Added mips_print_register, which tries to scrunch as much
6283 information as possible on a screen...
6284 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6285 under mips-pinsn.c), I don't see anything mips-specific here,
6286 and I don't see it being all that useful anyway.
6289 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6290 Use more register names (rather than hard-cases numbers).
6292 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6294 * Hack up 3.90.11 changes:
6296 * Makefile.dist (depend): parameterize $(GCC).
6297 Add solib.c and solib.o.
6298 (readline): Fix vpath for both absolute or relative SRCDIR.
6300 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6301 Also, let the part I didn't understand at least compile so
6302 I can test the rest. FIXME.
6304 * dbxread.c: Fix thinko using strcmp.
6305 (init_psymbol_list): declare static.
6306 (partial_symbol_file_open): Comment cleanups better, avoid
6307 cleaning up the string table since the caller will do that.
6308 Move the stat for mod time into symbol_file_command, temporarily.
6309 (There should be a mod time for each symbol file, eventually,
6310 to control its rereading. FIXME.)
6312 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6313 SunOS, which gives error for shared libs otherwise. (From
6314 Schaefer, probably FIXME needs work for portability.)
6316 * solib.c: Move #include "param.h" to work.
6317 Lowercase all the Uppercase Letters In the Messages.
6318 (find_solib): Clean up inferior_so_name for debug printouts.
6319 Allow no argument, to mean all shared libraries.
6321 * symmisc.c: include param.h to get CLEAR_SOLIB.
6323 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6325 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6326 to 3.90.11. ChangeLog entries below are from this.
6328 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

6334 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6338 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6340 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6342 * sparc-opcode.h Added single-operand version of rett.
6344 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6346 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6347 Put parens around gcc_p in expansion.
6349 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6351 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6353 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6355 * Changes for Sun shared libraries:
6356 blockframe.c (find_pc_partial_function): If a non-text symbol
6357 is found, set *address = pc - FUNCTION_START_OFFSET.
6358 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6359 Disable breakpoints instead of giving an error.
6360 source.c (select_source_symtab): Initialize cs_pst.
6361 symmisc.c: Call CLEAR_SOLIB if defined.
6362 symtab.h: Make text{low,high} CORE_ADDR not int.
6363 (psymtab): New field addr.
6365 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6366 (record_misc_function): Give correct type for N_DATA symbols.
6367 (condense_misc_bunches): do "misc_function_count = j" regardless
6369 Take code which is shared between symbol_file_command and
6370 add_file_command and put it into partial_symbol_file_{open,read}.
6371 Split add_file_command into add_file_command and add_file.
6372 Make psymtab_to_symtab read in the string table if the file
6374 Two new parameters to read_dbx_symtab and start_psymtab.
6375 tm-sunos.h: New file.
6377 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6379 * infcmd.c: Change cont_command to continue_command and "cont"
6382 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6384 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6386 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6388 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6389 size 1,2,4,8 rather than size < 8.
6391 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6392 as necessary, not just once.
6394 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6396 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6398 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6400 * tm-news.h: Add CALL_DUMMY_*.
6402 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6404 * config.gdb: In list_host, list_target, use ${i}, not $i.
6406 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6408 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6410 * sparc-opcode.h: Change all store floating-point state register
6411 instructions to have the right match & lose fields.
6413 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6415 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6417 config.gdb: If srcdir != ., create readline directory and
6418 copy a makefile into it.
6420 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6421 consistency with POSIX.
6423 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6424 when we exit its exp_valid_block.
6426 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6428 * Makefile.dist: Bump version to 3.91.3.
6430 * Clean up handling of breakpoint commands (somewhat).
6431 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6433 inferior.h: Add breakpoint_proceeded to inferior status struct
6434 and globals; save it and restore it.
6435 (clear_breakpoint_commands): Cleanup, remove old #define.
6437 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6438 (save_inferior_status, restore_inferior_status): handle it also.
6439 (proceed): Remove earlier code that set breakpoint_proceeded.
6440 It is now set only in clear_proceed_status.
6441 (clear_proceed_status): Cleanup, use bpstat_clear rather
6442 than clear_breakpoint_commands. No callers need the stop_bpstat
6443 between clear_proceed_status and proceed.
6445 infcmd.c: Add breakpoint_proceeded definition and comment.
6446 (cont_command, jump_command, signal_command): Move call to
6447 clear_proceed_status right next to call to proceed.
6449 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6450 caller's argument while running down the chain of breakpoints.
6451 Use new variable "breakpoint_proceeded" to determine when
6452 a command that it executes moves the inferior past the
6454 (bpstat_clear): Handle NULL argument.
6455 (bpstat_clear_actions): Avoid useless call to
6456 breakpoint_auto_delete.
6457 (delete_breakpoint): Clean up bpstat's that are pointing to
6458 the deleted breakpoint from the stop_bpstat chain.
6459 (breakpoint_auto_delete): Simplify.
6461 * Clean up handling of EOF, error on stdin, etc. This was
6462 prompted by a network problem that caused gdb to go into an
6463 infinite loop filling up its malloc'd memory.
6465 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6466 not clear_breakpoints_commands, which is now gone.
6467 (main): If command_loop returns (e.g. from EOF on stdin), do
6468 a quit_command (looping back to command_loop if quit_command
6469 doesn't really quit).
6470 (command_loop): check result from command_line_input and
6471 exit if it returns NULL, rather than passing the NULL to
6473 (gdb_readline): Free malloc'd result space before returning
6476 * utils.c (query): Handle C-d to mean "yes", just as if the
6477 input was not a terminal. Also avoid infinite loop if EOF
6478 occurs in mid-input-line before newline. This allows
6479 query to be used at EOF on stdin with reasonable results.
6481 * infrun.c (proceed): Set breakpoint_proceeded.
6483 * values.c (value_as_long): Avoid infinite recursion for enums.
6484 (_initialize_values): Fix typo in help msg (kingdon).
6486 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6487 RL_LIB for linking. This allows -lreadline for linking
6488 and nothing for dependencies, once readline is a real library.
6490 * config.gdb: Jim Kingdon: give useful error message if the
6491 host or target type is not recognized.
6493 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6494 it just defines it. Dumb, but deal with it.
6496 * Jim Kingdon suggests:
6497 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6499 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6501 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6503 * Clean up Bothner's changes.
6505 * blockframe.c (clear_pc_function_cache): New function.
6506 * blockframe.c: remake cache_pc_function_* static.
6507 * dbxread.c (symbol_file_command): remove references to
6508 cache_pc_function_* variables.
6509 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6510 * printcmd.c: Avoid kludging a global variable (addressprint)
6511 to avoid printing the address of a string twice. Instead,
6512 pass the format letter 's' down low enough that it can be seen
6513 to avoid this problem.
6514 (print_formatted): Pass format arg to value_print.
6515 (restore_addressprint): Remove function.
6516 (do_examine): Avoid hacking addressprint, cleanups and such.
6517 (print_frame_args): Add a comment to a Bothner change.
6518 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6519 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6520 to wipe out the values cached in blockframe.c.
6521 * symtab.c (find_method): Add comment saying how big you must
6522 allocate to be "big enough". Per being terse again.
6523 * valprint.c (val_print): Handle format letter "s" to print
6524 strings without addresses. Add comment to vtbl printing code
6525 which casts with wild abandon. Rearrange reference-printing
6527 @0xaddr: value (print w/addressprint)
6528 value (print w/~addressprint)
6529 @0xaddr (parameter lists w/addressprint)
6530 or nothing (parameter lists w/o addressprint)
6532 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6534 * Merge more changes from Per Bothner:
6536 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6537 annoying) that I tried to improve it. Here are my suggestions.
6539 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6542 Do automatic de-reference when taking the address of a reference.
6544 Don't deref_ref when printing parameter lists.
6546 More attempts at treating refernences properly.
6548 In val_print, if deref_ref==0, don't print dangling " = ".
6550 Add COERCE_REF macro, which de-references an REF.
6552 * Merge changes from Per Bothner:
6554 * Fixed (Sony news)-specific configuration problems.
6555 * Fixed other problems with using vanilla pcc and libc (enum problems;
6556 assumption that vsprintf exists).
6557 * Some major speed-ups (finc_pc_partial_function now caches a match;
6558 parsing avoids duplicate symbol_lookup calls).
6559 * Changed handling of baseclasses (no longer use baseclasses field
6560 of struct type, use the first n_baseclasses fields instead).
6561 * Various minor changes/fixes, most C++-related.
6564 Cache the most previous match from find_pc_partial_function.
6565 (Save both low and high ends of matching function's pc range.)
6566 This speeds up the loop of infrun.c:wait_for_inferior quite
6567 a bit, and makes step/next commands much zippier.
6569 Added an enum->int cast (otherwise, some compilers barf).
6571 No longer set baseclass offset to 0, since multiple
6572 inheritance now mostly works.
6573 Added a number of casts, to shut up compiler warnings
6574 (after stabs where made enums, not ints).
6575 When discarding a symbol table (in symbol_file_command),
6576 must clear the cache introduced in blockframe.c.
6577 Don't convert $vtbl_ptr_type to vtbl any more.
6578 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6579 Mask off sign bit emitted by g++ for virtual table offset.
6580 Set voffset to -1 (not 1) for static member functions.
6582 Changed parsing/lexing of names to avoid doing symbol lookup twice
6583 (once when lexing to determine symbol class, once for real).
6584 Now only call symbol_lookup once. Fields of 'this' win especially big.
6586 Subpress printing addr twice in the case of 'x/s addr'.
6588 lookup_basetype_type is no longer used.
6589 Add find_methods as recursive helper function to decode_line_1.
6590 This allows multiple inheritance to work.
6591 Also, once one or more matches has been found, do not look in
6592 base-classes. (Baseclass methods would be overridden, anyway.)
6594 Removed baseclasses array in struct type.
6595 Instead of using baseclasses[i], use fields[i-1].
6596 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6597 Changed sign convention of voffset (previous was inconsistent).
6599 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6601 Used to assume existence of vsprintf. Re-written to not need it
6602 if HAVE_VPRINTF is undefined.
6604 typecmp was too pessimistic. Made it less so.
6606 Don't print space after address.
6607 If vtable points to a misc symbol (with 0 offset), print it,
6608 since that indicates the actual class of the object.
6609 Changed ype_print_derivation_info to use new inheritance
6610 scheme (without baseclasses vector).
6612 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6613 Also, changes needed because TYPE_BASECLASSES were removed.
6615 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6617 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6620 If there is no path set, and the symbols don't indicate what directory
6621 a file was compiled in, look in the current directory. But either
6622 a path or a known compilation directory will prevent this.
6625 Three independent bug fixes:
6626 * Remove the #if 0 block that breaks some stuff.
6627 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6628 adapt gdb to either SunOS 4.0.* or 4.1.
6629 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6632 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6635 (type_print) Demangle the name being printed.
6636 (type_print_base) Handle botched demangling without coredump (tiemann).
6639 (check_stub_method): Document routine.
6640 (tiemann) fix bug for no-arg functions
6641 Avoid clobbering beyond end of malloc'd storage.
6642 Terminate the argument list properly.
6644 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6646 * Changes merged by John Gilmore:
6649 In breakpoint_1, use new print_address_symbolic instead
6650 of find_pc_partial_function. (This forces use of assembler-level
6651 addresses, and avoids misleading non-mangled source-level names.)
6653 Generalize ansi argument such that -1 means skip arglist totally.
6654 Removed global variable print_ansi_qualifiers (which made
6655 code non-reentrant), in favor of extra explicit arguments
6656 to internal routines.
6658 Add new helper function print_address_symbolic.
6659 Use find_pc_misc_function instead of find_pc_partial_function
6660 (since we want assembler-level symbols here).
6662 Print unknown function as just "f (...)", not "f (...) (...)".
6663 Use new fputs_demangled explicitly.
6665 Fixed a typing violation (problem: value.h cannot be imported
6666 without renaming many variable in this file).
6667 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6668 decode_line_1: Moved forward some never-reached code.
6669 Made decode_line_2 skip function prologues correctly.
6671 fputs_filtered should not demangle by default.
6672 Add new fputs_demangled to demangle on demand..
6674 Change value_struct_elt to use value_primitive_field (using recursive
6675 utility function search_struct_field). This allows foo.bar to work
6676 for multiple inheritance (so far only for data fields).
6677 Change check_field in the same way (recursive helper function
6678 to support multiple inheritance).
6679 (Note: there are more of these problems that I haven't fixed.
6680 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6681 value_of_this: 'this' symbol name is now just "this", note "$this".
6683 Don't print static members.
6684 Avoid printing "members of <type>" if there are none.
6685 Simplified type_print_derivation_info by merging duplicate code.
6686 Remove useless blank lines in type_print_base (ptype command).
6688 Added declaration of new routine value_primitive_field.
6690 Added value_primitive_field which is generalized version of
6691 value_field that can handle multiple inheritance (non-zero offsets etc).
6692 Re-implemented value_field to call value_primitive_field.
6694 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6696 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6697 delete the whole environment. Karl Berry reported the bug.
6698 * source.c - fix openp to avoid //'s in filenames, which
6699 trigger an Emacs bug causing it to not be able to find files
6700 when running gdb in a window.
6701 * dbxread.c - zap the #if 0 that botches the add-file code.
6702 It seems to work a lot better without all the code commented out.
6704 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6706 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6709 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6711 * Makefile - added a ${CFLAGS} to a couple of entries,
6712 added remote-sa.sparc.c
6713 * added remote.sa-sparc.c, a modification of remote.c
6714 which conducts a dialog directly with the SparcStation prom.
6715 * breakpoint.c, infrun.c, sparcdep.c added
6716 remote_insert_breakpoint(), and remote_remove_breakpoint()
6717 to breakpoint.c instead of directly writing breakpoint instructions.
6718 * sparcdep.c on remote_debugging,there is no need
6719 to remove signle step breakpoint instructions.
6720 * main.c added "-epoch" flag and "int epoch_interface" to main.c
6722 * printcmd.c - epoch interface sends lisp expressions to open up
6723 epoch windows on inspection.
6724 * valprint.c - added arrayprint, and addressprint and made adding
6725 format controls easier
6726 * wait.h added a couple of undef's because we were getting
6727 complaints about WSTOPSIG and WTERMSIG begin redefined.
6730 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
6732 * symtab.c (decode_line_1): Add support for handling method stubs
6733 in the type information.
6735 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
6737 * values.c (baseclass_addr): Run loop from INDEX+1 to
6738 N_BASECLASSES; otherwise, we can still get into a loop.
6739 @@ This should be restructured to use a cleaner search strategy.
6741 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
6743 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
6744 abbreviation "Tt" for tags which have the same name as their
6747 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
6749 * symtab.c (list_symbols): add ability to set breakpoints on all
6750 the functions which match a particular regular expression.
6752 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
6754 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
6755 should print ANSI qualifiers (such as `const' and `volatile').
6756 All callers changed to call with ANSI == 1, except from
6757 `check_method_stub', which uses old-style syntax.
6759 * symseg.h (struct fn_field): Remove unneccessary `args' field.
6760 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
6762 * values.c (check_stub_method): New function.
6764 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
6766 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
6767 * valprint (type_print_base): Ditto.
6769 * symtab.c (gdb_mangle_typename): New function.
6771 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
6773 * breakpoint.c (catch_command): New function. Provides a
6774 mechanism to set breakpoints based on catch clauses.
6775 (disable_catch): Similar, but disables breakpoints on catch
6777 (delete_catch): Similar, but deleted breakpoints on catch clauses.
6779 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
6781 * blockframe.c (blockvector_for_pc): New function.
6782 * blockframe.c (block_for_pc): Changed to call
6783 `blockvector_for_pc' and get the block itself.
6785 * stack.c (catch_info): New function. Prints info about
6786 exceptions which can be caught in the current frame.
6787 * stack.c (print_frame_label_vars): New function. Similar to
6788 `print_frame_local_vars'.
6789 * stack.c (print_block_frame_labels): Prints out labels that are
6790 defined in this frame. These labels are exceptions that can be
6793 * dbxread.c: Updated to handle N_CATCH symtab types.
6795 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
6797 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
6798 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
6799 when printing the type.
6801 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
6803 * valprint.c (val_print): Use `baseclass_addr' to access the
6804 baseclasses pointed to via the derived class object at VALADDR.
6806 * values.c (baseclass_addr): New function. Casts derived pointers
6807 to baseclass pointers taking virtual baseclasses and multiple
6808 inheritance into account.
6810 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6814 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6816 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
6817 exp_valid_block field correctly.
6819 * infrun.c (wait_for_inferior): When checking "don't even think
6820 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
6821 also check step_resume_breakpoint.
6822 Insert breakpoints and continue (not step) if
6823 step_resume_break_address != NULL, even if another_trap.
6824 If trap_expected and we enter sigtramp, then set up a
6826 If trap_expected is set when we hit the step_resume_break,
6828 When calling resume and trap_expected says tell resume to step
6829 (2 places), also check step_resume_break_address.
6831 * infrun.c (wait_for_inferior): Don't set
6832 prev_{pc,sp,func_{start,name}} before calling wait ().
6833 Do set them after exiting loop.
6834 Move their declarations outside functions.
6835 (start_inferior): Initialize them.
6837 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6839 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
6840 Restore old code which distinguishes between trap_expected and
6841 running_in_shell, just make the latter take any non-TRAP signal,
6844 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
6846 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
6847 xconfig/3b1 (CC,PINSN_CC): Define.
6849 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.

6854 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
6856 * param.h, tm-88k.h: Define ADDR_BITS_*.
6857 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
6858 printcmd.c (do_one_display): Use them.
6860 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
6861 xm-88k.h: Define USG_UTILS.
6863 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6865 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
6866 (printf_command): Add from_tty parameter.
6868 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
6870 * value.h: Add optimized_out field and change lazy field to
6871 char. Add macro VALUE_OPTIMIZED_OUT.
6873 * i386-pinsn.c: Change from Eirik Fuller to write to stream directly
6874 instead of stuffing things in buffers (oappend, etc).
6876 * breakpoint.c (bpstat_do_actions): If *BSP is set to NULL by
6877 execute_command, exit both loops.
6879 * Makefile.dist: Don't set TARGET_ARCH. Add .c.o rule.
6881 Tue May 1 17:07:23 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6883 * Makefile.dist (RAPP_OBS, rapp),
6884 rgdb.c, rserial.c, rudp.c, serial.c, udp.c, xdep.h,
6886 m68k-xdep.c, coredep.c: Wrap in #if !defined (RDB).
6888 * valops.c (value_struct_elt), values.c (value_static_field):
6889 Change error messages to remove references to `info methods'.
6891 Tue Apr 24 10:25:10 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6894 infrun.c (start_inferior): Add START_INFERIOR_HOOK.
6895 infcmd.c [SHIFT_INST_REGS]: New code.
6896 findvar.c (read_relative_register_raw_bytes): Return a value.
6897 infcmd.c (do_registers_info): Check value from
