3 * arm-opcode.h, m88k-opcode.h, pn-opcode.h, np1-opcode.h,
4 pyr-opcode.h, tahoe-opcode, vax-opcode.h: Removed -
5 these are all essentially the same as the versions
6 in ../include/opcode. The remaining *-opcode.h here
7 are not quite so obviously the same, and need study.
8 * arm-pinsn.c, gould-pinsn.c, m88k-pinsn.c, pyr-pinsn.c,
9 tahoe-pinsn.c, vax-pinsn.c: Change so these include
10 opcode/FOO.h (actually ../include/opcode/FOO.h)
11 instead of the recenntly departed opcode-FOO.h files.
12 * sparc-pinsn.c: Now that we're using the much tighter
13 opcode table in ../include/opcode/sparc.h, we shouldn't
14 need to sort the opcodes before dis-assembly.
16 * symtab.h, symmisc.c: Make cplus_struct_default be const.
17 * symtab.h, buildsym.c: Add and use INIT_CPLUS_SPECIFIC macro.
18 * symmisc.c: Remove unused 'nfields' variable.
19 * buildsym.h: Add extern decl of unknown_symtype_complaint,
20 since it used used by partial-stab.h (included two places).
21 * partial-stab.h: Re-arrange DBXREAD_ONLY #ifdefs so that
22 we should never hit the default case (until new stab codes
23 are added). Hence, we can leave the complaint in the
24 default case in even when DBXREAD_ONLY is off.
25 * partial_stab.h: Recognize a pair of N_SO stabs (one for the
26 directory, one for the filename proper) without peeking ahead.
27 * dbxread.c, mipsread.c: Because of previous change, don't need
28 ugly CHECK_SECOND_N_SO macro.
29 * buildsym.h, dbxread.c, mipsread.c: Make next_symbol_text a
30 macro that invokes a function pointer in next_symbol_text_func.
31 * mipsread.c: Added comments various places to
32 explain what is going on.
33 * mipsread.c (parse_symbol): Support the new (SGI-specific?)
34 symbol types stStruct, stUnion, and stEnum.
35 Also, some fixes in the code for dealing with tags.
36 * mipsread.c: Change handling of startup_file_start and _end
37 - now just use the textlow and texhigh of a psymtab
38 to check if we've found the startup-file.
39 * mipsread.c: Replace s_idx by global cur_sdx in many places.
40 This is so mips_next_symbol_text can get at it.
42 Thu Dec 26 19:52:01 1991 Fred Fish (fnf at cygnus.com)
44 * dbxread.c, symmisc.c: Move add_psymbol_to_plist() from
45 dbxread.c to symmisc and change name to add_psymbol_to_list.
46 Ditto for add_psymbol_addr_to_plist(). Also expand their
47 body to not use ADD_PSYMBOL_VT_TO_LIST.
49 * dwarfread.c: Remove add_psymbol_to_list() and convert usages
50 to the ADD_PSYMBOL_TO_LIST macro.
52 * ieee-float.c: Change "#ifdef DEBUG" to "#ifdef IEEE_DEBUG"
53 to avoid collision with the DEBUG for ADD_PSYMBOL_VT_TO_LIST.
55 * partial-stab.h, symfile.h: Move definitions of the macros
56 ADD_PSYMBOL_TO_LIST and ADD_PSYMBOL_ADDR_TO_LIST from
57 partial-stab.h to symfile.h. They aren't stab specific.
58 Change ADD_PSYMBOL_VT_TO_LIST to use memcpy rather than strncpy.
60 Tue Dec 24 11:38:08 1991 John Gilmore (gnu at cygnus.com)
62 * Makefile.in: Roll VERSION to 4.3.2.
64 Mon Dec 23 13:54:35 1991 Per Bothner (bothner at cygnus.com)
66 * m68k-opcode.h, mips-opcode.h, sparc-opcode.h: Deleted.
67 * m68k-pinsn.c, mips-pinsn.c, sparc-pinsn.c:
68 Include <opcode/FOO.h> instead of <FOO-opcode.h>.
70 * symtab.h, symtab.c, coffread.c, dwarfread.c, symmisc.c,
71 dbxread.c: The TYPE_CPLUS_SPECIFIC structure is now only
72 allocated when it is needed. Until it is needed, it points
73 to a shared statically allocated structure.
75 * buildsym.h, buildsym.c, dbxread.c: Remove the kludgy code
76 in read_ofile_symtab to recognize two initial N_SO stabs,
77 and let process_on_symbol handle it. This is cleaner, more
78 efficient, and lets mipsread.c share the same code.
80 * symfile.h, partial-stab.h: Move ADD_PSYMBOL_VT_TO_LIST
81 and related macros to here ...
82 * dbxread.c: ... from here.
83 * symmisc.c: Move the "overflow" handling from
84 ADD_PSYMBOL_VT_TO_LIST macro into new function extend_psymbol_list.
85 * dwarfread.c: Re-write add_psymbol_to_list to use
86 ADD_PSYMBOL_VT_TO_LIST macro.
88 * mipsread.c: Extend mipsread.c to handle stabs-style symbols
89 encapsulated in ecoff symbols. This enable full g++ debugging.
90 * partial-stab.h: Move the code for pre-scanning symbols
91 and building psymtabs to an include file, out from dbxread.c.
92 This way, the same code can also be used by mipsread.c.
93 * dbxread.c, buildsym.h: Various changes to allow some functions
94 to be used by mipsread.c (also some arguable stylistic changes).
96 * tm-mips.h: Define BLOCK_ADDRESS_ABSOLUTE, at least for now,
97 since mips-tfile puts relocatable addresses into LBRAC/RBRAC
100 * mipsread.c: Replace code to handle ambiguous tag blocks.
101 Instead of allocating a TYPE_CODE_UNDEF, guess (by looking
102 at types and offsets) if a tag is a struct, union, or enum.
103 Still patch it later if we find out for sure.
104 * mipsread.c: In various ways, replace Forin's
105 ideo-syncratic code by code that fits better with the
106 rest of gdb, for both stabs-based and ecoff-based symtabs.
107 E.g. use end_psymtab; don't do extra passes over FDR table to
108 pre-partition global data; don't use external symbols to
109 create static/global symbols (just put them in the
110 misc_vector); use ADD_PSYMBOL_TO_LIST macro; don't
111 sort psymtabs or symtabs; use obstacks more.
113 * symtab.c, mipsread.c, dbxread.c, buildsym.c:
114 ANSIfy: Replace bcopy by memcpy, bzero by memset.
116 Sun Dec 22 19:31:04 1991 Fred Fish (fnf at cygnus.com)
118 * solib.c (locate_base): Fix uninitialized variable that was
119 causing return of random value to callee.
121 * config/mh-amix, config/mh-i386v4: Change to find alloca by
122 compiling and linking alloca.c, even when it is not strictly
123 required. Also arrange to link with -ltermlib rather than
126 * Makefile.in: Move TERMCAP definition to prior to inclusion
127 of host makefile fragments so it can be overridden.
129 Fri Dec 20 16:33:39 1991 John Gilmore (gnu at cygnus.com)
131 * xcoffread.c (read_symbol_lineno): Logic error in incrementing
132 symbol table entry number. (From Metin Ozisik.)
134 Fri Dec 20 11:36:38 1991 Fred Fish (fnf at cygnus.com)
136 * config/mh-i386v4: Change XM_CLIBS to "-lc /usr/ucblib/libucb.a"
137 so compiles with native compilers (without builtin alloca) can
138 pick up the version from the bsd emulation library. However, we
139 search the standard C library first so we don't pick up lots of
140 other broken stuff from libucb.a, that we *don't* want.
142 * configure.in, tm-amix.h, tm-i386v4.h, xm-amix.h, xm-i386v4.h:
143 Change svr4 references to sysv4.
145 * source.c: Move declaration of external function index to
146 front of file so it is in scope for all references.
148 * utils.c (error, fatal): Make definitions consistent with
149 defs.h declarations (declared as "volatile void").
151 Fri Dec 20 10:55:36 1991 John Gilmore (gnu at cygnus.com)
153 * rs6k-opcode.h: Bugfix sfe and stbrx. By Al Kossow.
155 Wed Dec 18 17:09:06 1991 Stu Grossman (grossman at cygnus.com)
157 * command.h, defs.h, eval.h, expression.h, remote-sa.sparc.c,
158 sparc-tdep.c, symtab.h, target.h, value.h, vx-share/ptrace.h,
159 vx-share/xdr_ptrace.h, vx-share/xdr_rdb.h: ANSIfy enums.
161 Mon Dec 16 12:31:46 1991 Fred Fish (fnf at cygnus.com)
163 * config/mt-amix, config/mt-i386v4: Add solib.o to TDEPFILES
164 for these SVR4 systems.
166 * symfile.c (symbol_file_add): When verbose is set, print
167 the names of files from which symbols are being loaded, as
168 when from_tty is true.
170 * solib.c: Completely reorganized (rewritten) to support
171 SVR4 shared libraries in a manner very close to the original
172 SunOS implementation. This support is expected to change and
173 become more general at some future time. The SVR4 version
174 does not yet work for attached processes, for example.
176 * dwarfread.c: Arrange in dwarf_build_psymtabs() for the
177 relocation address to be valid whether or not symbols are
178 being read from a shared library or an executable. Use the
179 relocation address recorded in the psymtab when reading
180 full symbol tables (in read_ofile_symtab). Ensure that the
181 relocated address ranges are recorded in partial symtabs.
183 * elfread.c: Add new function elf_interpreter() to return the
184 string from the ELF ".interp" section. This is the interpreter
185 that the kernel tries to run and feed the executable to.
186 Expand arguments to record_misc_function to include a type arg.
187 Modify elf_symtab_read() to supply the type arg, and to do symbol
188 relocations for symbols read in from shared libraries.
190 * procfs.c: Add new functions proc_base_address() and
191 proc_address_to_fd(), used by shared library support.
193 * tm-svr4.h: Add macros to support SVR4 shared libraries.
194 Definitions for SOLIB_ADD, SOLIB_CREATE_INFERIOR_HOOK,
195 CLEAR_SOLIB, and DISABLE_UNSETTABLE_BREAK.
197 Fri Dec 13 20:11:26 1991 John Gilmore (gnu at cygnus.com)
199 * infrun.c, remote-eb.c, remote-nindy.c, remote-vx.c: Remove
200 unused START_INFERIOR_HOOK.
202 * remote-eb.c: Change timeout to 24 seconds (*10 fits in byte)
203 to account for slow loading from floppies.
204 (eb_create_inferior): New fn, from eb_start and
205 nindy_create_inferior.
206 (eb_close): Only use log_file if nonzero.
207 (eb_xfer_inferior_memory): If not writing, then read!
208 (eb_read_inferior_memory, eb_write_inferior_memory): Return length.
209 (eb_kill): A new no-op.
210 (eb_mourn_inferior): Remove breakpoints, then generically weep.
212 Fri Dec 13 16:09:23 1991 Fred Fish (fnf at cygnus.com)
214 * breakpoint.c, findvar.c, infrun.c, putenv.c, stack.c: Fix
215 miscellaneous comparisons of integer with NULL that elicit
216 compiler warnings about comparison of integer with pointer, when
217 NULL is ((void *) 0) rather than just a bare 0.
219 Wed Dec 11 13:02:58 1991 John Gilmore (gnu at cygnus.com)
221 * breakpoint.c (breakpoint_re_set_one): Disable each breakpoint
222 while we reset it, in case of problems. Print breakpoint number
225 * buildsym.c (read_struct_type): Avoid sun3 compiler bug with
228 * source.c (find_source_lines): If getting file mod time fails,
231 * target.c (target_xfer_memory): If errno is set, return it,
234 Tue Dec 10 04:07:22 1991 K. Richard Pixley (rich at rtl.cygnus.com)
236 * Makefile.in: infodir belongs in datadir.
238 Sun Dec 8 21:13:33 1991 Michael Tiemann (tiemann at sphagnum.cygnus.com)
240 * symtab.h (struct fn_field): Add new fields `is_private',
241 `is_protected', `is_stub', making room by reducing the size of
243 (struct fn_fieldlist): Delete the fields `private_fn_field_bits'
244 and `protected_fn_field_bits'.
245 (TYPE_FN_{PRIVATE,PROTECTED}_BITS): Deleted.
246 (SET_TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
247 (TYPE_FN_{PRIVATE,PROTECTED}): Deleted.
248 (TYPE_FN_FIELD_{STUB,PRIVATE,PROTECTED}): New macros.
249 * valops.c, valprint.c, symtab.c: All callers updated.
251 * buildsym.c (read_struct_type): Delete the `visibility' field
252 from `struct next_fnfield', and rework code so that visibility
253 info is stored into the fn_field directly. Also, hacked to set
254 TYPE_FN_FIELD_STUB for both static and normal member functions.
256 Sat Dec 7 18:13:11 1991 Fred Fish (fnf at cygnus.com)
258 * i386-tdep.c: Fix a problem on i386 systems where buffered code
259 stream access was failing to take into account the minimum size
260 granularity of the code section. For now, the buffering is simply
261 disabled. There is a similar problem in the i386 disassember code
262 that has not yet been fixed (FIXME).
264 * gmalloc.c: Use macros to hide some of the ugly casting required
265 in the previously applied fix for pointers with high bits set.
267 Sat Dec 7 16:49:35 1991 John Gilmore (gnu at cygnus.com)
269 * Makefile.in: Roll VERSION to 4.3.1.
271 Sat Dec 7 04:12:35 1991 John Gilmore (gnu at cygnus.com)
275 * Makefile.in: Roll VERSION to 4.3
276 * README, TODO, WHATS.NEW, depend: Update.
278 * inflow.c (terminal_inferior): Avoid error msg if attached.
280 * gmalloc.c: Fix bug that causes malloc & free to
281 fail on systems where pointers have the high bit set (0x800efcf0
282 for example). The problem is that the difference between two
283 pointers is a signed integer, so the computation
285 (char *) 0x800efcf0 - (char *) 0
287 yields a negative value. The sign of the result of the modulus
288 operator is machine dependent for negative operands, thus it is
289 possible for it to end up negative. From Fred Fish.
291 Sat Dec 7 00:00:15 1991 K. Richard Pixley (rich at rtl.cygnus.com)
293 * Makefile.in: install using INSTALL_PROGRAM and INSTALL_DATA.
294 added clean-info. added some standards.text support and made it
295 look like our other Makefiles.
297 * configure.in: mark this directory target dependent. configure
298 now runs entirely in objdir so make existence tests and
299 references against ${srcdir}.
301 Fri Dec 6 08:30:36 1991 Fred Fish (fnf at cygnus.com)
303 * dwarfread.c (enum_type, struct_type): Fixes for opaque and
304 anonymous enumerations, structures, and unions. Now passes all
305 the current gdb test suite tests.
307 Thu Dec 5 22:46:13 1991 K. Richard Pixley (rich at rtl.cygnus.com)
309 * Makefile.in: idestdir and ddestdir go away. Added copyrights
310 and shift gpl to v2. Added ChangeLog if it didn't exist. docdir
311 and mandir now keyed off datadir by default.
313 Thu Dec 5 21:53:21 1991 John Gilmore (gnu at cygnus.com)
315 * symtab.c (decode_line_1): If SKIP_PROLOGUE leaves us in
316 mid-line, be more careful about possibly advancing to the next line.
318 Thu Dec 5 18:59:51 1991 Michael Tiemann (tiemann at cygnus.com)
320 * cplus-dem.c (cplus_demangle): Call `string_need' when
321 null-terminating a partially-computed string.
323 Thu Dec 5 18:19:43 1991 Fred Fish (fnf at cygnus.com)
325 * dwarfread.c (enum_type): Build a correct TYPE_NAME, add a
326 symbol to the symbol table for each member of the enum.
328 * dwarfread.c (struct_type): Build a correct TYPE_NAME.
330 * dwarfread.c (add_enum_psymbol): New function to extract enum
331 member names and add them to the partial symbol table while
332 building partial symbol tables.
334 Thu Dec 5 17:31:05 1991 John Gilmore (gnu at cygnus.com)
336 * symtab.c (check_stub_method): Must allocate two extra argument
337 slots (one for `this', one for arglist terminator).
339 Thu Dec 5 10:51:05 1991 Fred Fish (fnf at cygnus.com)
341 * inflow.c (child_terminal_info): Supply missing '"' character.
343 * buildsym.c (define_symbol): Supply missing parenthesis.
345 Thu Dec 5 03:34:21 1991 John Gilmore (gnu at cygnus.com)
347 * coredep.c (fetch_core_registers): Fencepost error. Fixed by
348 Jay Lepreau <lepreau@cs.utah.edu>.
350 * inflow.c: Remember whether GDB has a terminal. Avoid switching
351 terminals back and forth if we don't have one.
353 * c-exp.y (parse_number): Zero is not an unsigned int constant!
354 * dbxread.c (read_dbx_symtab): Enum type numbers can be in (1,2) form.
356 Improve type parsing.
357 * buildsym.c (define_symbol, read_range_type): Add
358 long_kludge_name that passes the names of range types being
359 defined, down to where we must choose between 'int' and 'long'
360 variants. This fails on Sun C anyway since the compiler itself is
361 confused between int and long.
362 (read_array_type, cleanup_undefined_types): Correct the size of
363 array type whose element-type size isn't immediately known.
365 Early preparation to blow away many builtin types, building them
366 on the fly as needed. Don't compare types to builtin types with
367 ==; examine the relevant fields instead.
368 * coffread.c (process_coff_symbol: C_ARG, C_REGPARM): Avoid ==.
369 * buildsym.c (define_symbol, case 'p'): Avoid ==.
370 * valops.c (value_arg_coerce): Avoid ==. Don't assume host and
371 target types are the same.
372 * valprint.c (val_print): I finally understand arrays, remove FIXME.
374 * symmisc.c (printpsyms_command): Reduce redundancy, and put all
375 addresses in GDB itself into parens for easy cleanup and diffing.
377 Wed Dec 4 21:05:30 1991 Fred Fish (fnf at cygnus.com)
379 * dwarfread (enum_type): Arrange for the order of enumeration
380 members to match the source code order; not the order in the
381 Dwarf information, which is explicitly reverse order.
383 Wed Dec 4 18:24:39 1991 John Gilmore (gnu at cygnus.com)
385 * main.c (input_from_terminal_p): Check whether GDB has a
387 (initialize_main): Revise doc for `set editing'.
389 Wed Dec 4 15:36:39 1991 Fred Fish (fnf at cygnus.com)
391 * dwarfread.c (struct_type): Handle structures and unions which
392 contain DIE's other than just member dies.
394 Wed Dec 4 01:59:05 1991 John Gilmore (gnu at cygnus.com)
396 * symfile.c (reread_symbols): Avoid kludging mtime_set, now that
399 Tue Dec 3 17:24:57 1991 John Gilmore (gnu at cygnus.com)
401 * Makefile.in: VERSION 4.2.96.
403 * main.c (initialize_main): Revise command descriptions.
404 * command.c (show_user): `info user' -> `show user'.
405 * symtab.c (_initialize_symtab): Typo in `info types' desc.
407 * coffread.c (coff_symfile_read): Avoid select_source_symtab,
408 since it is not needed and can cause errors when examining ".o"s.
409 (read_coff_symtab, decode_base_type): Use complain, not printf.
410 Print symbol name, not its number.
411 Remove "#if defined(clipper) #define BELIEVE_PCC_PROMOTION", which
412 someday should go in a clipper target config file.
414 * symfile.c (compact_misc_function_vector): Handle empty vector.
415 (complain, clear_complaints, syms_from_objfile): Fix complaint
417 * xcoffexec.c: Change syms_from_objfile caller.
419 * sparc-xdep.c: Force tm-file as tm-sparc.h, to make it compile
420 when configured for cross debugging. FIXME, this needs a more
423 Mon Dec 2 11:04:05 1991 Per Bothner (bothner at cygnus.com)
425 * mips-tdep.c (init_extra_frame_info): Float register
426 'i' has gdb-internal number 'FP0+i', not '32+i'.
427 * mipsread.c (new_symbol): Translate g++ special
428 symbol "$t" to "this".
430 Sat Nov 30 21:29:55 1991 Steve Chamberlain (sac at cygnus.com)
431 Changes due to include file renaming:
433 * xcoffread.c: internalcoff.h ->coff/internal.c,
434 coff-rs6000.h ->coff/rs6000.h
435 * mipsread.c: coff-mips.h ->coff/mips.h

441 stab.gnu.h ->aout/stab_gnu.h
443 * coffread.c: internalcoff.h ->coff/internal.h
444 * buildsym.c: stab.gnu.h ->aout/stab_gnu.h
445 * depend Updated to take the above into account.
447 Fri Nov 29 16:59:25 1991 Fred Fish (fnf at cygnus.com)
449 * configure.in: Add SVR4 i386 configurations.
451 * config/mh-i386v4, config/mt-i386v4, tm-i386v4.h, xm-i386v4.h:
452 New files for i386/SVR4.
454 * tm-i386v.h: Allow START_INFERIOR_TRAPS_EXPECTED and
455 DECR_PC_AFTER_BREAK to be predefined by files including
458 * i386-tdep.c: Add supply_gregset(), fill_gregset(),
459 supply_fpregset(), and fill_fpregset() functions, which are
460 target dependent support functions for the SVR4 /proc register
463 * dwarfread.c (enum_type, struct_type): Expand recognized
464 compiler generated tags to include symbols beginning with '.' as
467 * symtab.c (sources_info): Change simple printf of error message
470 Fri Nov 29 16:04:21 1991 Roland H. Pesch (pesch at cygnus.com)
472 * doc/gdb.texinfo: remove leading comments that survived M4 but
473 described its role in the doc; add one more font to colophon;
474 strengthen disclaimer about unsupported configs.
476 Wed Nov 27 01:23:41 1991 John Gilmore (gnu at cygnus.com)
478 Fix bugs in C++ debugging.
480 * symtab.h: target_type is not used in record types.
481 Eliminate TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT. Eliminate
482 lookup_method_type. Add TYPE_TYPE_SPECIFIC macro.
484 * symtab.c (lookup_member_type): Don't chain them up, just
485 allocate one in symbol_obstack when we need one.
486 (allocate_stub_method): Build stub in symbol_obstack.
487 (check_stub_method): Move here from values.c. Don't deallocate
489 (lookup_method_type): Gone now.
491 * buildsym.c: Handle g++ v1 stabs a little bit better.
492 Change some C++ parsing error()s to complain()ts.
493 * buildsym.c, findvar.c, printcmd.c, symtab.c: Make unions and
494 structs have the same representation and work the same as far as
496 * buildsym.c, symtab.c, values.c: Remove all references to
497 TYPE_MAIN_VARIANT and TYPE_NEXT_VARIANT.
499 * valops.c: Improve comments and indentation. Only call
500 check_stub_method when the stub flag is on.
501 * valprint.c: Fix or mark minor bugs and unportabilities.
503 * coffread.c (anonymous unions): Allocate a cplus structure.
505 * mipsread.c: Eliminate "template" types. Build new, real
506 types whenever we need them. Allocate cplus structures as needed.
507 Bulletproof the type parsing a bit more. Mark storage leaks.
508 (parse_type): Copy TYPE_TYPE_SPECIFIC when copying a real type
509 on top of a partial type.
511 Fri Nov 22 16:39:57 1991 John Gilmore (gnu at cygnus.com)
513 * inflow.c (terminal_inferior): Check the results of ioctl's, and
514 print a message if any of them fail.
515 (terminal_ours_1): Store result of ioctl's for debugging, but
516 don't print (the terminal isn't ours...).
518 * tm-tahoe.h (FRAME_ARGS_ADDRESS): No need to offset from frame
521 * m2-exp.y (MAX, MIN): Rename to MAX_FUNC, MIN_FUNC to avoid
522 conflicts with system header files.
524 Fri Nov 22 08:27:40 1991 John Gilmore (gnu at cygnus.com)
526 * Roll VERSION to 4.2.95.
528 * buildsym.c, coredep.c, mem-break.c, xcoffread.c: Put <stdio.h>
529 first, before defs.h.
530 * config/mh-i386sco: Override compiler to gcc, print warning.
531 * configure.in: Handle i386-none-aout rather than i386-aout-none.
532 * infptrace.c, language.h, utils.c: Lint.
533 * m2-exp.y: #undef MAX and MIN in case system includes set them.
534 * xm-tahoe.h: Set HOST_BYTE_ORDER. Include system versions of
535 {BIG,LITTLE}_ENDIAN and the INT_MAX family first, to avoid
536 redefinition warnings.
537 * defs.h: Reorder things so that the xm-file gets first crack
538 at #define's, followed by defs.h and then the tm-file.
539 * Makefile.in: Remove spaces after 'ignore exit code' - flags.
540 Late-model BSD 'make's don't cope with them.
542 Thu Nov 21 23:48:56 1991 John Gilmore (gnu at cygnus.com)
544 * Makefile.in: Roll new files into various lists.
546 Thu Nov 21 18:26:11 1991 Fred Fish (fnf at cygnus.com)
548 * dwarfread.c (struct_type): Must initialize the c++ specific
549 portion of union types as well as struct types, since gdb attempts
550 to reference the c++ specific info for both types.
552 Thu Nov 21 10:23:52 1991 John Gilmore (gnu at cygnus.com)
554 * Makefile.in: Roll VERSION to 4.2.90.
556 * defs.h: Incorporate param.h into defs.h. All users changed.
557 * param-no-tm.h: Change users to define TM_FILE_OVERRIDE instead.
558 * param.h, param-no-tm.h: Removed.
559 * Update copyrights in all changed files.
560 * dbxread.c, dwarfread.c, inflow.c, infrun.c, m2-exp.y, putenv.c,
561 solib.c, symtab.h, tm-umax.h, valprint.c: Lint.
562 * tm-convex.h, tm-hp300hpux.h, tm-merlin.h, tm-sparc.h,
563 xm-merlin.h: Avoid host include files in target descriptions.
564 * getpagesize.h: Removed, libiberty copes now.
565 * Makefile.in: Remove getpagesize.h, param.h, param-no-tm.h.
567 * exec.c (exec_files_info): If `verbose' is set, show file offset
570 * main.c: Use getcwd rather than getwd.
571 * standalone.c: Fake getcwd rather than getwd.
572 * xm-*.h: Remove fake values of MAXPATHLEN.
574 * xcoffexec.c: Add /* */ to #if 0'd thing to help ANSI.
576 Wed Nov 20 18:35:56 1991 John Gilmore (gnu at cygnus.com)
578 * Remove gdb/hp-include. Support for HP a.out oddities should be
579 in BFD, not in GDB. Move gdb/hp-include/a.out.h to include/a.out.hp.h.
581 * infptrace.c, tm-sun386.h: Cashier <a.out.gnu.h>, remove refs.
583 * configure.in, xconfig, tconfig, Makefile.in, doc/gdbint.texinfo:
584 Makefile fragments for various hosts and targets now come from
585 gdb/config/mh-* and gdb/config/mt-*. This is for consistency with
588 * rs6000-pinsn.c, rs6k-opcode.h: Clean up.
589 * rs6k-opcode.def: Delete.
591 Wed Nov 20 05:04:40 1991 Fred Fish (fnf at cygnus.com)
593 * dwarfread.c: Recognize obsolete form of AT_element_list
594 attribute still used by at least one AT&T compiler, and possibly
597 Tue Nov 19 07:53:55 1991 Fred Fish (fnf at cygnus.com)
599 * dwarfread.c (enum_type, struct_type): Ignore names invented by
600 helpful compilers for anonymous structs, unions, and enums.
602 * c-exp.y, m2-exp.y: Add defines for yymaxdepth, yy_yys, and
603 yy_yyv, so multiple parsers produced by SVR4 versions of yacc
604 can coexist in the same executable without collision.
606 * symtab.h: Add declaration for lookup_template_type() to kill
607 compiler warnings about conversions from int to pointer.
609 Mon Nov 18 17:45:18 1991 Fred Fish (fnf at cygnus.com)
611 * procfs.c: Move inclusion of defs.h to before param.h, as in
612 all the other source files that include both. This is required
613 to supply some typedefs that are used in files included by param.h.
615 * m68k-tdep.c (m68k_skip_prologue): Add generic m68k support for
616 skipping function prologues, ala the other cpu families (i386,
617 mips, m88k, etc). Add the ability to skip movm and fmovm
618 instructions in the prologues. Still needs support for profile
619 (-p compiled) prologue sequences (FIXME).
621 * tm-68k.h: Change SKIP_PROLOGUE macro to use the new generic
622 m68k prologue skipping function by default.
624 * tm-altos.h, tm-isi.h: Continue to use the old definition of
627 Mon Nov 18 15:12:45 1991 John Gilmore (gnu at cygnus.com)
629 * Makefile.in: Remove tdesc stuff, and extra blanks before colons.
630 * blockframe.c: Remove tdesc-related code. Default
632 * infrun.c: Remove tdesc-related code.
633 * m88k-tdep.c (frame_chain_combine, init_frame_pc): Remove copies
634 of defaultable things.
635 * tm-m88k.h: New file, common to all Moto 88k target configs.
636 Derived from tm-delta88.h.
637 * tm-delta88.h: Use it.
638 * xm-m88k.h: Common file for 88K hosts. Remove obsolete stuff.
639 * xm-delta88.h: Use it.
640 * tm-*.h: Remove FRAME_CHAIN_COMBINE macros, since all are
642 * coffread.c: Remove tdesc stuff.
643 * tconfig/delta88, tconfig/m88k: Remove tdesc stuff.
644 * xconfig/m88k: Rename tm-88k.h to tm-m88k.h.
646 Mon Nov 18 13:51:37 1991 Per Bothner (bothner at cygnus.com)
648 * source.c (open_source_file): If openp fails, try again
649 using just the base (non-directory) part of the filename.
650 This solves various annoying problems, such as when the
651 source was compiled with an absolute pathname - and the
652 source files have moved. Or if the source was compiled
653 using a relative pathname, it can be more convenient
654 to just specific the source directory to the dir command.
656 Mon Nov 18 00:04:41 1991 Fred Fish (fnf at cygnus.com)
658 * cplus-dem.c (munge_function_name): Add missing third arg to
659 instance of call to do_type().
661 * dwarfread.c: Changes to match new dwarf.h. Remove
662 AT_deriv_list, AT_loclist, AT_incomplete, AT_const_data,
665 Sun Nov 17 16:20:53 1991 Michael Tiemann (tiemann at rtl.cygnus.com)
667 * symtab.h (struct type): Moved C++-specific fields into new type
668 `struct cplus_struct_type'. Now takes 10% less memory. Many
670 * symtab.c (init_type): Don't set fields belonging to
671 TYPE_CPLUS_SPECIFIC unless TYPE is TYPE_CODE_STRUCT.
672 * buildsym.c (read_type): Allocate TYPE_CPLUS_SPECIFIC for
674 (read_struct_type): Ditto. Also, add comments about how we can
675 deduce TYPE_VPTR_FIELDNO from inheritance info and fieldname info.
676 * coffread.c (decode_base_type): Allocate TYPE_CPLUS_SPECIFIC for
678 (read_struct_type): Ditto.
679 * dwarfread.c (struct_type): Ditto.
681 * symtab.c (read_range_type): Don't set TYPE_MAIN_VARIANT.
682 (lookup_pointer_type): Don't use or set TYPE_MAIN_VARIANT.
683 (lookup_reference_type): Ditto.

692 * mipsread.c (parse_partial_symbols): patch to keep DEC C
693 compiler from making gdb bomb out. Thanks to Ed Santiago!
695 Thu Nov 14 19:27:30 1991 Fred Fish (fnf at cygnus.com)
697 * symfile.c: Add function compact_misc_function_vector() to
698 remove duplicate misc function vector entries. See comments
699 in source for why this is necessary/desirable.
701 * dwarfread.c: Add misc function type parameter to internal
702 record_misc_function(). Remove calls to init_misc_bunches()
703 and condense_misc_bunches(), these are now done in elfread.c.
705 * elfread.c: Add support for reading bfd canonical symbol tables
706 and generating misc function vector entries for global and
707 absolute symbols. Do calls to init_misc_bunches() and
708 condense_misc_bunches() where they will enclose all calls to
709 record_misc_function(), including those in dwarfread.c.
711 Thu Nov 14 17:02:11 1991 Roland H. Pesch (pesch at cygnus.com)
713 * doc/Makefile.in: new targets gdb.me, gdb.ms, gdb.mm
714 (roffable documentation).
715 * doc/gdb.texinfo: embedded hints (as comments) for better
716 texi2roff conversion.
718 Thu Nov 14 13:18:25 1991 John Gilmore (gnu at cygnus.com)

732 Motorola 88000 port without tears, I mean without tdescs.
734 * m88k-tdep.c: Blow away all tdesc stuff.
735 Provide functions for all the frame-related macros in
736 tm-delta88.h. Adopt i960-style EXTRA_FRAME_INFO.
737 (examine_prologue, frame_find_saved_regs, skip_prologue): borrow
738 from i960-tdep.c and adapt to the function prologues on the 88k.
739 (read_next_frame_reg): Borrow from mips-tdep.c.
740 FIXME: frame_locals_address should go away.
742 * tm-delta88.h: Dump all the tdesc stuff.
743 Macros for all frame-related stuff call fns of same name.
744 Remove duplicated definitions. FP_REGNUM becomes same as
747 * xm-88k.h: Eliminate lots of library dependencies, now handled
748 in libiberty. Eliminate KDB nonsupport.
750 * doc/gdbint.texinfo: Add rudiments on frames. FIXME, add more.
753 * stack.c (frame_info): Mark frameless functions.
754 Print locals address (FIXME, remove if same).
755 * blockframe.c: Comment changes, FIXME after.
756 * coffread.c: Even without TDESC, need to zap "@" symbols.
757 Don't register for wierd format names; change the names in BFD.
759 * alloca.c, language.c, tdesc.c: Lint.
760 * tdesc.c, tdesc-lib: FIXME: remove these.
762 Tue Nov 12 19:30:22 1991 John Gilmore (gnu at cygnus.com)

771 Allow setting breakpoints on C++ destructors.
772 * valops.c (destructor_name_p): Don't check TYPE_HAS_DESTRUCTOR,
773 since it lies. Rely on callers to catch missing destructors.
774 * symtab.c (decode_line_1): For example (see above), here.
775 * buildsym.c, symtab.h: Remove TYPE_FLAGS_HAS{CON,DE}STRUCTOR
776 flags since they are no longer used.
778 Fixes to support C++ methods with functional parameters.
779 * c-exp.y (func_mod rule): Allow (and ignore) list of parameter
780 types in a function type.
781 * eval.c (parse_and_eval_type), value.h: New function,
782 parse_and_eval_type, is based on old code from check_stub_method.
783 But don't actually evaluate the cast, since that calls
784 value_cast(), whcih may fail. Just extract the type
785 from the parsed expression.
786 * values.c (check_stub_method): While looping through the
787 arguments, adjust depth *after* parameter has been handled.
788 Replace call and setup of parse_and_eval with new function
791 Tue Nov 12 09:40:07 1991 Fred Fish (fnf at cygnus.com)
793 * utils.c, rem-multi.shar: Remove fixed arg count version of
796 * altos-xdep.c, arm-xdep.c, coffread.c, command.c, convex-xdep.c,
797 core.c, dwarfread.c, gould-xdep.c, infcmd.c, language.c,
798 m88k-xdep.c, main.c, printcmd.c, pyr-xdep.c, source.c,
799 sun386-xdep.c, symm-xdep.c, umax-xdep.c, values.c, xcoffread.c:
800 Change all instances of use of fixed args concat() to variable
801 args concat() now located in libiberty.
803 Tue Nov 12 07:23:46 1991 John Gilmore (gnu at cygnus.com)
805 * Makefile.in: Add xcoffread.c, xcoffexec.c.

807 * xconfig/rs6000, tconfig/rs6000: New files.
808 * buildsym.c: Add hooks for xcoffread.c.
809 * rs6000-pinsn.c, rs6000-tdep.c, rs6000-xdep.c, tm-rs6000.h,
810 xm-rs6000.h, rs6k-opcode.def, rs6k-opcode.h: New files.
811 * xcoffexec.c: New file for handling AIX shared libraries.
813 Mon Nov 11 19:14:31 1991 Fred Fish (fnf at cygnus.com)
815 * core.c: Minor rewording of message to user containing name of
816 (and possibly arguments to) the program that generated a core
819 * elfread.c: Remove the register_addr() stub now that it is no
822 * procfs.c: Move misplaced #endif for ATTACH_DETACH. Add new
823 fetch_core_registers() function for core file support.

827 * dwarfread.c (dwarf_psymtab_to_symtab): Remove leftover call
828 to do_cleanups() which resulted from a previous change.
830 * elfread.c: Re-enable compilation of register_addr() stub
831 whenever it is not supplied by coredep.c
833 Sat Nov 9 00:40:32 1991 John Gilmore (gnu at cygnus.com)
835 Add tracking of object files (that contain symbols) to gdb.
836 This includes a "struct objfile" that owns symtabs and psymtabs
837 that were read in from that binary file.
839 * symfile.h: Add struct objfile. Add pointer to the objfile
840 into the struct sym_fns.
841 Replace global `symfile' and `symfile_mtime' with
842 `symfile_objfile'. Add global object_files chain.
844 * symfile.c: Move param.h above symtab.h.
845 (sort_misc_function_vector): Add.
846 (syms_from_objfile): Was syms_from_bfd.
847 (symfile_open): Now returns objfile.
848 (allocate_objfile): New.
849 (free_objfile): New, replacing free_all_.*symtabs.
850 (symfile_init): Takes objfile arg, puts it in sym_fns result.

871 (dbx_alloc_type): Check file number, not sym number, for -1.
872 (find_symbol_in_list): Add for xcoffread.
873 (start_symtab): Default typevector is empty. Keep reusing same
875 (end_symtab): Take objfile argument and pass it to
876 allocate_symtab. Don't make a symtab if no blocks or symbols.
877 Handle empty typevector.

900 (fn_fieldlists voffset): avoid non-int bitfield.
901 (struct symtab): Add objfile * and objfile_chain * of symtabs.
902 (struct partial_symtab): Add objfile * and objfile_chain * of
903 psymtabs. Remove symfile_name.
905 * symmisc.c: Lose free_all_symtabs, free_all_psymtabs.
906 (printsyms_command): Rename from print_symtabs. Add selective
907 listing if 2nd argument given. Print objfile info.
908 (printpsyms_command): Rename from print_partial_symtabs. Ditto all.
909 (printobjfiles_command): New; prints objfiles lists, and checks

912 * symfile.h, symfile.c, symtab.h: Lint
914 Fri Nov 8 23:38:48 1991 John Gilmore (gnu at cygnus.com)
916 * command.c: Include param.h.
917 * defs.h (warning_setup, warning): Declare.

923 Thu Nov 7 18:26:15 1991 Steve Chamberlain (sac at rtl.cygnus.com)
925 * Makefile.in: link with libiberty after libreadline, since
926 readline might want something in libiberty.
927 * m88k-xdep.c: Fixed the register offsets in the ptrace_user
928 struct for BCS 88k machines.
929 * xm-m88k.h: don't define USIZE if already defined.
930 * configure.in: Added delta88 target.
932 Thu Nov 7 04:51:19 1991 John Gilmore (gnu at cygnus.com)
934 * am29k-pinsn.c, am29k-opcode.h: Fix decoding of mtacc, dmac, fmac.
936 * tm-*.h: Remove READ_DBX_FORMAT, COFF_FORMAT, and
937 READ_MIPS_FORMAT, which have been unused since BFD. Still
938 remaining is COFF_NO_LONG_FILE_NAMES.
939 * tm-sun3.h, tm-altos.h: Remove detritus accidentally left from
940 function calling code moved to m68k-tdep.c.
942 Wed Nov 6 17:21:59 1991 John Gilmore (gnu at cygnus.com)
944 * coffread.c: Eliminate c_nsyms in favor of c_naux.
945 Complain if no auxents on .bf and .ef FCN symbols, and assume
946 lots of line numbers.
947 (init_linenos, enter_linenos): Use a sentinel at the end of the
948 read-in linenos, to make for a fast, safe loop-end test.
950 Wed Nov 6 02:54:08 1991 Steve Chamberlain (sac at cygnus.com)
952 * coffread.c (read_coff_symtab): coffread used to rely on the
953 x_sym.x_misc.x_lnsz.x_lnno field giving the # of linnos in a
954 function. Two of the formats I'm using (29k and 88k) don't seem to
955 set it. Ths patch to fcn_last_line and (enter_linenos) is an
956 attempt to use the actual size of the linno table in the file to set
957 the number of linenos to process.
959 Tue Nov 5 22:47:46 1991 Steve Chamberlain (sac at cygnus.com)
961 * Makefile.in: put a - infront of the mv y.tab.c c-exp.tab.c and
962 mv y.tab.c m2-exp.tab.c, so that if bison is used, and the files
963 are created in place, so the mv fails, then the make continues.
965 Tue Nov 5 16:47:47 1991 Per Bothner (bothner at cygnus.com)
967 Add C++ as a separate language.
968 * defs.h (enum language): Add language_cplus.
969 * dwarfread.c (end_symtab): Support language_cplus.
970 * c-exp.y: Add new struct language_defn cplus_language_defn.
971 Don't set c to be the default language (see main.c).
972 * c-exp.y (yylex): Only look for field of this if
973 language is C++. (First difference from C!)
974 * language.c: Add case branches for C++ (currently, all
975 the same as C). Also, add c++ to "usage" note for "set lang".
976 * valprint.c (typedef_print). Add case branches for C++.
977 * main.c (main): New way to set initial language: Look at
978 file extension of psymtab containing main(). (Same as we
979 do for symtabs, but avoid loading the symtab yet.)
980 * symtab.c: New routine find_main_psymtab(), used by main()
981 to set initial language.
982 * symfile.c (allocate_symtab): Move code for mapping file
983 extensions-> languages to new deduce_language_from_filename().
985 Fix a C++ problem when looking for methods in super-classes.
986 There was confusion between base and derived types.
987 * valops.c (value_fn_field): Change function interface.
988 * values.c: Use new value_fn_field interface.
990 Mon Nov 4 10:49:33 1991 Per Bothner (bothner at cygnus.com)
992 * infrun.c: Fixed typo in comment.
993 * utils.c: All the v*fprintf emulation is now in libiberty,
994 so we can get rid of some junk.
995 * xm-sun3os4.h, xm-sun4os4.h, xconfig/decstation, xconfig/i386sco,
996 xconfig/sun3os4, xconfig/sun4os4: Don`t need HAVE_STRSTR any more.
997 * m68k-pinsn.c (print_insn_arg): Support BB/BW/BL
998 type operands, as used by branch instructions.
999 * gmalloc.c: Fix prototype of memcpy.
1000 * elfread.c: Comment out register_addr, since it conflicts
1001 with the one in coredep.c.
1002 * buildsym.h: Remove extern declarations of two functions
1003 that are really static in buildsym.c.
1004 * tm-mips.h: Add symbolic names for more registers.
1005 * mips-xdep.c (store_inferior_registers): Use new register names.
1006 * xm-mips.h: Simplify REGISTER_U_ADDR, since it is now
1007 only used for core files, not ptrace. Therefore,
1008 the KERNEL_U_ADDR hack is no longer needed.
1009 The mapping to ptrace number is now in in mips-xdep.c.
1010 * mips-xdep.c: Define REGISTER_PTRACE_ADDR (using the
1011 mapping from the old REGISTER_U_ADDR), and use it
1012 in {fetch,store}_inferior_registers.
1013 * mipsread.c: Rename #include ecoff.h to new name coff-mips.h.
1014 * mips-tdep.c (mips_push_dummy_frame, mips_pop_frame):
1015 Save/restore FP regs correctly (?).
1016 * dbxread.c: Remove duplicate define_symbol and type_synonym_name
1017 (these had been previously moved to buildsym.c).
1018 Hence, define_symbol becomes extern instead of static.
1019 * buildsym.c (read_struct_type): Comment out bogus handling
1020 of C++ operator methods. Minor hacking of reading of class
1021 contexts. Make define_symbol non-static, so dbxread.c can call it.
1023 Fri Nov 1 11:05:47 1991 John Gilmore (gnu at cygnus.com)
1025 * mipsread.c (read_mips_symtab, read_the_mips_symtab): Use real
1026 filename with error messages.
1027 * stack.c (frame_select_command): Rename to select_frame_command
1028 to avoid "fr" and "fra" having nonunique completions.
1029 * symfile.c (sort_symtab_syms): Ignore sort of zero symtab *.
1030 (symfile_init): Print file format name when unable to handle it.
1031 (free_named_symtabs): Use BLOCKVECTOR rather than obsolete BLOCKLIST.
1032 * symmisc.c (free_symtab): Only free linetable if nonzero.
1033 * symtab.h: Remove obsolete BLOCKLIST macros.
1035 Thu Oct 31 18:12:43 1991 Stu Grossman (grossman at cygnus.com)
1037 * infrun.c (wait_for_inferior): another stepi/nexti fix. Ensure
1038 that stop_step is 1 at bottom of main loop. I don't know why this
1039 needs to be done, but it helps me sleep better at night.
1041 Sun Oct 27 18:18:39 1991 Stu Grossman (grossman at cygnus.com)
1043 * main.c (initialize_history): Read history after reading all
1046 Sun Oct 27 14:09:25 1991 John Gilmore (gnu at cygnus.com)
1048 * buildsym.c: Break out initial malloc sizes.
1049 (record_line): Record directly in a subfile. Alloc on demand.
1050 (compare_line_numbers): Add from xcoffread.c.
1051 (end_symtab): New params say whether to sort pendings and
1052 linetable. Patch block stabs if defined. Shrink linetable before
1053 allocating the symtab.
1054 * buildsym.h: Delete line_vector* and prev_line_number. Add
1055 global_stabs and file_stabs for xcoffread.
1056 * dbxread.c (start_subfile): Move to buildsym. Change above calls.
1057 * symtab.h: LINETABLE(symtab) can now be null. Zap LINELIST.
1058 * symmisc.c, symtab.c: Cope with null LINETABLEs.
1060 * blockframe.c: Pass fromleaf to INIT_EXTRA_FRAME_INFO.
1061 * tm-29k.h, tm-88k.h, tm-i960.h, tm-irix3.h, tm-mips.h, tm-pyr.h,
1062 tm-sparc.h: Accept fromleaf parameter.
1063 * c-exp.y (yyerror): Pass error message if given.
1064 * configure.in: Add rs6000 host and target.
1065 * inflow.c (new_tty): O_NOCTTY kludge for RS/6000.
1066 * symfile.h (entry_point): Add.
1068 Sat Oct 26 00:16:32 1991 John Gilmore (gnu at cygus.com)
1070 * buildsym.c: New file. Breaks out symbol-table-building routines
1071 from dbxread.c, so they can be shared with xcoffread.c.
1072 * buildsym.h: New file. Declarations for buildsym.c users.
1073 * dbxread.c: Remove large chunks into buildsym.c.
1074 * Makefile.in: Add buildsym.c and buildsym.h.
1076 * symfile.c (syms_from_bfd): New routine.
1077 (add_symbol_file): Call it to do the real work.
1078 (syms_from_bfd): Initialize entry_point before calling symfile_init.
1079 * symtab.h, symfile.c, coffread.c, mipsread.c, dwarfread.c:
1080 Avoid declaring or setting entry_point (symfile.h & symfile.c cope).
1082 Fri Oct 25 10:58:16 1991 Mark Eichin (eichin at cygnus.com)
1084 * cplus-dem.c (cplus-demangle): added support for templates, static
1085 data, and the new (correct) mangling for destructors.
1087 * dwarfread.c: (dwarfwarn): created a varargs version of
1088 dwarfwarn, for non __STDC__ compilers.
1090 * c-exp.y: (yylex): added match for "template" token.
1091 (typebase): added TEMPLATE name '<' type '>' clause, for explicit
1092 specification of template types.
1094 * symtab.c: (lookup_template_type): new function for finding
1095 templates in symbol table.
1096 (type_name_no_tag): changed to explicitly check for s/u/e at the
1097 beginning of the symbol - if it is a template, none of these will
1098 be there (but the name will still contain spaces.)
1100 Fri Oct 25 18:59:32 1991 Per Bothner (bothner at cygnus.com)
1102 Various fixes to improve g++ debugging.
1103 * symtab.h: Add is_const and is_volatile flags for each method.
1104 These are bit fields - take their space from voffset,
1105 which shrinks to 30 bits. Since voffset is now a bitfield,
1106 make it unsigned for portability. This changes its interpretation
1107 slightly: Static methods now have voffset 1 instead of -1,
1108 and virtual offsets start at 2, not 1.
1109 * symtab.c: Renamed gdb_mangle_typename to gdb_mangle_name,
1110 since it now returns an entire magled method name, not just
1111 the type part. This avoids some duplication.
1112 It also allows us to correctly mangle const and volatile
1113 methods (using the new is_const and is_volatile bit fields
1115 * valprint.c (type_print_base), values.c (check_stub_method):
1116 Simplify by using new gdb_mangle_name.
1117 * values.c (value_headof): Fix to correctly handle single
1118 inheritance (actually two fixes, either of which suffices).
1119 * dbxread.c (read_struct_type): Handle const and volatile
1121 * dbxread.c (read_struct_type): Yet one more place where
1122 we must handle '\\' continuations.
1123 * valprint.c (vtbl_ptr_name): Add final '\0'.
1125 Fri Oct 25 16:06:38 1991 Stu Grossman (grossman at cygnus.com)
1127 * tm-sparc.h, tm-68k.h (EXTRACT_RETURN_VALUE): fix output of
1128 short return values for sparc and 68k. Patch from Paul Eggert.
1130 * coffread.c, coredep.c, i386-xdep.c: install patches for
1131 SysV/386 3.2 from Mauro DePalma.
1133 Fri Oct 25 02:02:13 1991 John Gilmore (gnu at cygnus.com)
1135 * core.c (core_file_info), exec.c (exec_file_info): Print file
1136 type. Use printf_filtered.
1138 * valops.c (value_fetch_lazy): Avoid 0-length fetches.
1140 Thu Oct 24 23:06:40 1991 Fred Fish (fnf at cygnus.com)
1142 * dwarfread.c: Add casts to remove compiler warnings.
1144 * tm-3b1.h, tm-68k.h, tm-altos.h, tm-amix.h, tm-hp300bsd.h,
1145 tm-hp300hpux.h, tm-isi.h, tm-news.h, tm-pn.h, tm-sun2.h,
1146 tm-sun3.h: Remove locally duplicated code for calling functions
1147 in the inferior. The only differences were in the specific trap
1148 vectors used and whether or not an fpu was present. These are
1149 now handled by appropriate definitions of BPT_VECTOR and
1150 HAVE_68881 respectively. Other minor obvious cleanups.
1152 * valops.c: Correct a minor misspelling.
1154 * utils.c: Remove local BSD/USG hacks that are now in libiberty.
1156 * dwarfread.c: Remove prototype for dwarfwarn. Does not work
1159 Thu Oct 24 09:33:44 1991 John Gilmore (gnu at cygnus.com)
1161 * stack.c (frame_command): Always print. Use new
1162 frame_select_command to select a frame without printing.
1164 * dwarfread.c: Use <varargs.h>, since <stdarg.h> is not portable.
1166 Thu Oct 24 01:32:51 1991 Fred Fish (fnf at cygnus.com)
1168 * dwarfread.c: New file for DWARF debugging format support.
1170 * elfread.c: New file for ELF object file format support.
1172 * procfs.c: New file for SVR4 /proc (process file system) support.
1174 * tm-amix.h, xm-amix.h, tconfig/amix, xconfig/amix: New files for
1177 * xm-svr4.h, tm-svr4.h: New files for SVR4 support.
1179 * xm-m68k.h: New file for host machines with m68k cpu.
1181 * Makefile.in: Add elfread.c and dwarfread.c to SFILES_MAINDIR.
1182 Add elfread.o and dwarfread.o to OBS.
1184 * symfile.h: Add "elf" to list of supported formats in comment.
1186 * c-exp.y, defs.h, symtab.h, valprint.c: Add three new builtin
1187 types to gdb, builtin_type_long_double, builtin_type_complex, and
1188 builtin_type_double_complex. Add and use new TARGET_SHORT_BIT,
1189 TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
1190 TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
1191 TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
1192 types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
1194 * infrun.c: When using SVR4 /proc interface instead of ptrace(),
1195 call proc_set_exec_trap() to setup child to stop at first instruction.
1197 * inftarg.c: When using SVR4 /proc interface, call proc_wait()
1200 * m68k-tdep.c: Add new routines supply_gregset(), fill_gregset(),
1201 supply_fpregset(), and fill_fpregset(), which are machine
1202 dependent support routines for SVR4 /proc interface.
1204 * utils.c: Add warning_setup() and warning(). Warning() behaves
1205 the same as error() except that it returns normally rather than
1206 jumping back to command level. Modules that don't want to call
1207 warning() for some reason, but want to produce their own warnings,
1208 can call warning_setup() to ensure compatibility with the way
1209 warning() and error() deal with the terminal.
1211 * symtab.c: Make internal errors produce more useful messages.
1213 * tm-68k.h: Move code that is duplicated in almost every single
1214 m68k based machine's configuration files to this common file.
1215 Duplications in the configuration files still need to be removed
1218 * infrun.c (child_create_inferior): System V versions must call
1219 setpgrp() with no arguments, to comply with prototyping typically
1222 * munch: Add support for SVR4 style nm output.
1224 * dbxread.c, mipsread.c symmisc.c, symtab.c: Remove the object
1225 file specific fields from the partial symbol table structure and
1226 replace them with a pointer to private data for each different
1227 flavor of object file reader to initialize appropriately.
1229 Wed Oct 23 09:38:20 1991 John Gilmore (gnu at cygnus.com)
1231 * xconfig/sun[34]os4: Add note about strstr botch on sunos4.0.3c
1234 * mipsread.c (fixup_undef_type): New function. If a struct /
1235 union / enum is defined in a header file but nowhere else used,
1236 (by typedefing, pointer referencing or declaration) the mipsread code
1237 builds the complete tree for the structure but leaves its code as
1238 TYPE_CODE_UNDEF as it doesn't know what kind of aggregate it is.
1239 Guess its type based on the details of the members.
1241 Tue Oct 22 18:04:32 1991 Stu Grossman (grossman at cygnus.com)
1243 * infrun.c (wait_for_inferior): Check return value from
1246 Mon Oct 21 17:47:03 1991 Stu Grossman (grossman at cygnus.com)
1248 * infrun.c (wait_for_inferior): fix stepi/nexti that was broken
1249 by my last edit to this routine.
1251 Mon Oct 21 14:27:43 1991 John Gilmore (gnu at cygnus.com)
1253 * tm-sun3.h (FIX_CALL_DUMMY): problem with cross debugging.
1254 FIX_CALL_DUMMY does unaligned accesses and/or forgets to byte swap
1255 the values before putting them into the dummy code. (From Peter
1258 Mon Oct 21 10:04:39 1991 Steve Chamberlain (steve at rtl.cygnus.com)
1260 * configure.in: added ebmon target.
1262 Wed Oct 16 22:49:58 1991 John Gilmore (gnu at cygnus.com)
1266 * Makefile.in: Roll VERSION to 4.2.
1267 * README, TODO, WHATS.NEW: Update.
1269 * core.c (core_open): Improve error message for bad file.
1270 Pass .reg virtual memory address to fetch_core_registers to help
1271 it find the registers in the core-file header.
1272 * coredep.c (fetch_core_registers): Take new argument, use it,
1273 and pass it to register_addr to locate the block of registers.
1274 * xm-mips.h: Update KERNEL_U_ADDR for new scheme. Cleanup a bit.
1276 * dbxread.c (read_dbx_symtab, process_one_symbol): Handle
1277 Sequent N_FN_SEQ like everybody else's N_FN.
1279 * main.c: Circumvent SCO cc bug with #if !!defined(USG).
1280 * tm-i386v.h: #endif guck.
1281 * xconfig/i386*: Remove -Dgetpagesize()=4096 kludge.
1282 * xconfig/i386sco: Add HAVE_STRSTR to avoid ANSI bdeath.
1283 * xconfig/tahoe: Add REGEX, which seems to be missing.
1285 * coredep.c: Add <sys/types.h> for SCOnix.
1286 * dbxread.c (read_dbx_symntab): Avoid coredump on malformed file.
1287 * printcmd.c (print_formatted): Flush output before disassembly.
1289 Tue Oct 15 20:12:32 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1291 * doc/refcard.tex (sec "Working Files"): consistent metavars and
1292 other improvements, due to comments by François Pinard
1293 (pinard@iro.umontreal.ca)
1295 * doc/gdb.texinfo (appendix "Installing GDB"): changes in
1296 configure, and improvenets related to Pinard's refcard comments
1298 Tue Oct 15 08:45:12 1991 John Gilmore (gnu at cygnus.com)
1300 Changes from Fred Fish:
1301 * tm-68k.h (FPI_REGNUM): Add.
1302 * infrun.c (child_create_inferior): flush stdout and stderr
1304 * configure.in: Handle amigados, amix hosts and targets.
1305 * inflow.c: Handle TIOCGLTC_BROKEN for Amiga.
1307 From Andreas Schwab:
1308 * values.c (show_convenience): Use printf_filtered.
1309 * main.c (define_command): Check result of lookup_command for
1311 (echo_command): Use printf_filtered, and force output out.
1313 * dbxread.c (read_enum_type): Avoid Modula-2 kludge that breaks C
1315 * i387-tdep.c (double_to_i387): Fix typo for double_to_ieee_extended.
1316 * utils.c (_initialize_utils): If !ISATTY, don't paginate.
1317 * configure.in, tconfig/decstation, xconfig/decstation: Rename
1318 dec3100 to decstation.
1320 Mon Oct 14 13:37:50 1991 Roland H. Pesch (pesch at cygnus.com)
1322 * doc/gdb.texinfo: Catch up to changes recorded here in ChangeLog
1323 (nodes Continuing and Stepping; Memory; Targets) clarifications
1326 Fri Oct 11 23:27:06 1991 John Gilmore (gnu at cygnus.com)
1328 * tm-{irix3,mips,nindy960,pn,symmetry,vx960}.h: Move
1329 REGISTER_U_ADDR to corresponding xm- file. Sugg. by Peter Schauer.
1331 * symmisc.c (print_partial_symtabs): Add printpsyms debug cmd.
1333 * m68k-tdep.c (m68k_push_dummy_frame, m68k_pop_frame): Add
1334 generic routines for calling inferior functions.
1336 * blockframe.c (inside_main_scope, inside_entry_scope): New.
1338 * copying.awk: Filter formfeeds out of copying & warrantee.
1339 Make them available as `show copying' and `show warrantee' also.
1340 * main.c (print_gnu_advertisement): Advt `show' commands.
1342 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
1344 * mach386-xdep.c: Even when cross-compiling, leave in the
1345 core-file reading code.
1346 * core.c (get_core_registers): Avoid coredump if no .reg section.
1348 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
1350 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
1351 This avoids coredumps under `set print object on' in value_headof
1352 (called erroneously by value_from_vtable_info) for `p &struct'
1353 or `p *struct'. From Peter Schauer.
1355 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
1357 * Makefile.in: Roll version to 4.1.2.
1358 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
1359 size from BFD (but, FIXME, we don't yet read external nlists's and
1360 convert them to internal nlists's before handling them -- we still
1361 assume they have the same size and alignment.) Use SET_NAMESTRING
1363 * exec.c (exec_file_command): Move dead coff-encapsulation code
1365 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
1367 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
1369 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
1370 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
1372 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
1374 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1375 * mips-xdep.c (store_inferior_registers): Don't try to
1376 write the (pseudo) FP.
1377 * mipsread.c (parse_partial_symbols): Improved algorithm for
1378 setting pst->texthigh.
1380 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
1382 * doc/Makefile: make TEXINPUTS include . everywhere
1384 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
1386 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
1387 vestiges of typevectors, which were for symsegs and are no longer
1388 used. (From a question by Eliot Dresselhaus
1389 <dresselh@RFT30.nas.nasa.gov>).
1391 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
1393 * dbxread.c, coffread.c: static-ize functions that were
1394 gratuitiously external. (From Fred Fish.)
1396 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
1398 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
1399 until it is large enough.
1401 * dbxread.c (read_type): Handle error case slightly better.
1402 Make complaint message not C++-specific.
1404 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
1406 * infrun.c (wait_for_inferior): Fix step/next so that you only
1407 stop at the beginning of a new line. This fixes various problems
1408 with for loops, nested if-else's and switch statements.
1410 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
1412 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
1413 between symtabs and psymtabs become ordinary error()s.
1415 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
1416 properly, making "end pc" correct in shared lib psymtabs.
1417 (From Guy Harris <guy@auspex.com>.)
1419 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
1421 * dbxread.c: Enable, but soften, const_vol_complaint.
1422 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
1423 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
1424 should be file-scope, not global.
1425 (read_struct_type): Remove ancient multiple-inheritance warning.
1426 (read_range_type): Check base type, complain & patch if undefined.
1427 * stack.c (frame_info): Demangle the function name in `info stack'.
1428 (From Peter Schauer)
1430 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
1432 * eval.c (evaluate_subexp_for_address): Don't use
1433 TYPE_POINTER_TYPE directly (it might be zero if this type has
1434 never had a pointer created before); use lookup_pointer_type.
1435 * symtab.c (lookup_method_type): Arguments were swapped in all
1436 callers, so fix it here. I'm amazed this worked at all!
1438 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
1440 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
1441 "bss" rather than "data" symbols, but which still conflict.
1444 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
1445 * core.c (core_files_info): Shorten output.
1446 * exec.c (exec_files_info): Ditto.
1447 (build_section_table): Ignore zero-length sections.
1448 * language.c, printcmd.c: Lint.
1449 * language.h (get_frame_language): Declare.
1450 * saber.suppress: update.
1451 * stack.c (find_relative_frame): Remove complex code that was
1452 #if 0'd, stick with simple code. Lint.
1453 * saber.suppress: Update a bit.
1454 * symfile.c (add_symbol_file_command): Add "?" to question.
1455 * utils.c (parse_escape): Avoid \a due to bdead compilers.
1456 * value.h: Declare typedef_print.
1458 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
1461 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
1462 (Reported by Mark Peek <mark@imagen.com>.)
1464 * solib.c (solib_map_sections): Relocate all sections, even
1465 though only the text section's size is tracked. Mark ld_text
1466 for eventual elimination as we generalize to N sections.
1468 * infrun.c (wait_for_inferior): Don't check if the PC is in a
1469 call_dummy if we were stopped by a random signal that is being
1470 passed to the program. This produced wierd results when calling
1471 functions in the inferior and signals (e.g. SIGALRM) were in use.
1473 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
1475 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
1476 Bugfix from Paul Eggert <eggert@twinsun.com>.
1477 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
1478 * valprint.c (print_floating): Print 9 digits for IEEE floats.
1481 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
1483 * Makefile.in: Roll VERSION to 4.1.1.

1487 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
1491 * Makefile.in (VERSION): Set to 4.1.
1492 * language.c (set_language_command): Print useful help message,
1493 and restore the language string after giving help.
1494 * valprint.c (typedef_print): Print typedef in C or M2.
1495 * symtab.c (list_symbols): Use it.
1496 * main.c (main): Avoid any output before (gdb) prompt when -q.
1497 * language.c (set_language_command): Handle errors by restoring
1498 the language string to its current state (fix from A. Beers).
1499 * doc/gdbint.texinfo: Roll in information from README. Rearrange
1500 "how to install" and "how to print the doc" stuff so it drops
1502 * configure.in: Rename rtpc CPU to romp to match config.sub.
1503 * README, WHATS.NEW, TODO: Update for gdb-4.1.
1505 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
1507 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
1508 autoloading shared libs, copyright etc on GDB startup, clean up $_
1509 and $__ index refs, set/show listsize and related updates to list
1510 cmd. New host/target configs.
1512 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
1514 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
1515 from main Makefile.in version definition
1516 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
1518 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
1520 * doc/gdb.texinfo: merge new language-switching and lang-specific
1523 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
1525 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
1526 compilers (which may lack stddef.h).
1528 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
1530 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
1531 N_WARNING are the same except for the N_EXT bit, so just use their
1532 values alone, rather than OR-ing them with N_EXT.
1534 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
1536 * mipsread.c (parse_lines): Deal with negative extended line
1539 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
1540 global symbol conflicts.
1542 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
1544 * .gdbinit: Move 'set complaints' to top, so it runs even in
1545 case we aren't debugging GDB.
1546 * language.c (_initialize_language): Fix type check and range
1547 check documentation strings.
1548 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
1549 language.c can use it. (Though language.c should really not be
1550 handling warnings/errors the way it does, FIXME.)
1551 * symtab.c (lookup_primitive_type): const lint.
1553 Bugfix from Peter Schauer:
1554 * source.c (lines_to_list): Make signed, to avoid comparison
1555 going unsigned and complaining that -3 is too high for 21 lines.
1556 * stack.c (lines_to_list): Ditto.
1558 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
1560 * Makefile.in (HFILES): Add minimon.h.
1561 (VERSION): Roll version number to 4.0.95.
1562 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
1563 New rules for building distributions. Normal distribution
1564 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
1565 one level up from here; it calls make-proto-gdb.dir to build a
1566 directory `proto-gdb' which is an image of the release. The old
1567 `gdb.tar.Z' rule still works too.
1568 * config.sub, configure: Roll in latest from ..
1570 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
1572 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
1573 new-target, and new-config chapters; fix minor typos; come closer
1574 to usual GNU markup conventions for @file @samp @code @var.
1576 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
1578 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
1579 * mipsread.c (parse_partial_symbols): Enter the name of all
1580 structs/unions... into the psymtab so we can access them if the
1581 symtab is not read in.
1582 * mips-tdep.c: Remove some unneeded #includes.
1583 * xconfig/dec3100: Add HAVE_STRSTR.
1585 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
1587 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
1588 * c-exp.y, m2-exp.y: Lint.
1589 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
1590 * valprint.c (val_print_fields): Check for stub type.
1591 * mipsread.c (_initialize_mipsread): Avoid using
1592 builtin_type_void at initialize time.
1593 (mipscoff_symfile_read): use it now.
1595 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
1597 Merge multiple-language support, and partial Modula-2 support,
1598 from Andrew Beers <beers@cs.buffalo.edu>.
1600 * i387-tdep.c: New file, consolidates most 80387 support,
1601 and eliminates host dependency on double<->extended conversions.

1609 * mipsread.c (new_symtab): Use it. Minor formatting changes.
1610 * dbxread.c (end_symtab): Use it.

1620 (process_coff_symbol): #if 0'd for functions and params as above.
1621 (read_enum_type): Recognize Modula-2 BOOLEAN.
1622 * symtab.c (add_param_to_type): #if 0'd function to add a

1627 source.c, symfile.c, dbxread.c, breakpoint.c, core.c, exec.c,
1628 i387-tdep.c, infcmd.c, mips-tdep.c, stack.c, printcmd.c: Output
1629 hex with local_hex_string for Modula-2 support.
1631 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
1632 breakpoint condition language-independently.
1634 * parse.c: New file with the common code remains of expread.y.
1635 * parser-defs.h: New file with common declarations from expread.y.

1658 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1660 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
1661 * expprint.c: Look up expression opcodes in language-specific

1694 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
1696 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
1697 entries are enclosed herein. Not all of these changes
1698 have been merged into the master GDB sources -- check the
1699 ChangeLog above here for the merge log.
1701 Mon Jun 3 17:05:45 EDT 1991
1703 m2-exp.y Created. Tested outside of GDB for a few days. Proper
1704 operators were added, C specific operators and tokens
1705 removed. yylex() revamped to some extent. Still things
1706 missing from the grammar, such as sets.
1707 Tested for two weeks in GDB v3.5.
1709 Tue Jun 11 17:23:48 EDT 1991
1711 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
1712 so they are built-in. Sort of a hack.
1714 Fri Jun 14 12:53:51 EDT 1991
1716 m2-exp.y Added range checking for numeric constants. Any numeric
1717 constant is assumed to be of builtin type INTEGER unless:
1718 (1) it is octal or hexadecimal, in which case it is a
1719 CARDINAL; (2) it is too big to fit into an INTEGER, in
1720 which case it is a CARDINAL.
1721 eval.c Added simple range checking for +, -, and * on integers.
1722 Doesn't work very well for *, since 6 * 1,000,000,000 =
1723 1,705,032,704, which fails the simple test of result >=
1724 first_operand, no matter in what order the operands are.
1726 Tue Jun 18 14:11:30 EDT 1991
1728 Broke the parser into parts, one containing the C grammar and the other
1729 containing code to be shared by all of the grammars.
1731 The following files no longer exist:
1736 The following files were added:
1738 c-exp.y (The C grammar)
1739 m2-exp.y (The Modula-2 grammar)
1740 parser-code.c (Code that is shared by the above grammar)
1744 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
1745 now necessary to use the Bison compiler compiler, since it
1746 will generate function/variable prefixes other than yy.
1748 Tue Jun 18 16:47:49 EDT 1991
1750 symtab.[ch] Added the external variable working_lang, than holds the
1751 value of the current working language.
1752 Added the ennumerated type language_mode, with the values
1753 language_auto and language_manual, the former meaning that
1754 GDB sets working_lang as needed, and the latter meaning
1755 that the value of working_lang is totally under user
1757 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
1758 REAL, BOOLEAN and CHAR. Also added the type codes
1759 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
1760 utils.c Added set_language_command and show_language_command to
1761 implement the GDB support commands "set language" and
1763 expression.h A number of identifiers were added to the type exp_opcode
1764 to facilitate Modula-2 builtin functions, integer
1765 division, and array indexing.
1767 Wed Jun 19 13:25:58 EDT 1991
1769 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
1770 if the language specified by working_lang requires the use
1771 of strict typing of expressions. Eventually, even this
1772 will be able to be changed by the user.
1773 Added the macro RANGE_CHECK, which evaluates to non-zero
1774 if the language specified by working_lang requires the
1775 checking of a value against the domain of its type.
1776 Eventually, even this will be able to be changed by the
1778 language.[ch] Predicates involving types (simple_type, ordered_type,
1779 same_type, integral_type, numeric_type, character_type,
1780 boolean_type, float_type) are added. These predicates are
1781 based on the current value of working_lang, and are handy
1784 Wed Jun 19 15:39:34 EDT 1991
1786 eval.c Added the function type_array_rank which computes the rank
1788 valarith.c Added the funtion value_bool, which when given a integer
1789 value.h value (ie. struct value *) as an argument, it returns a
1790 boolean value (ie. struct value *) true if that integer
1791 is non-zero, and a boolean value false otherwise.
1792 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
1793 will print out properly.
1795 Wed Jun 19 16:36:34 EDT 1991
1797 valops.c Added the function value_capitalize, which returns it
1798 value.h argument capitalized if its argument is a lowercase
1799 letter, or the argument unchanged if its argument is not a
1801 valarith.c Added the function range_check_p, which returns non-zero
1802 value.h if its value argument is between the integral bounds upper
1804 Added the function range_check_enum_p, which makes sure
1805 that its value argument is a valid member of the domain of
1807 Added the function range_check_range_p, which makes sure
1808 its value argument lies between the upper and lower bounds
1809 of its type argument, which must be a ranged type.
1810 Added the function check_array_index, which range and type
1811 checks an index of an array.
1812 Added the function value_multi_subscript, which computes
1813 array[idx1,idx2...idxN], given a value array and an array
1814 of values representing indicies.
1815 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
1816 unpack_long to work with TYPE_CODE_BOOL and
1819 Wed Jun 19 18:04:08 EDT 1991
1821 symtab.c Stored pervasive types in a structure and make
1822 lookup_pervasive_type() a lookup function that was based
1823 on working_lang. If lookup_pervasive_type() returned
1824 non-zero, then that value was returned (a fix, since
1825 before it simply wouldn't return the pervasive type.)
1826 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
1827 non-zero if the language specified by working_lang means
1828 "conversion" when it says "cast".
1829 valops.c Added the function value_real_cast(), which performs a
1830 value.h *cast*, not a *conversion*, which is what value_cast()
1831 does when it can. In particular,
1832 value_cast(<float_type>,4) = 4.0, while
1833 value_real_cast(<float_type>,4) = some mess.
1834 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
1835 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
1836 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
1837 and MIN on integral types. *NOTE*: These are currently
1838 hardcoded to work only if there are 8 bits per storage
1840 eval.c Made logical functions call value_bool to return a
1841 properly typed boolean value, based on working_lang.
1843 Thu Jun 20 11:55:27 EDT 1991
1845 valprint.c Types now print out in a Modula-2 fashion. This works for
1846 the cases when the type is printed out step-by-step, that
1847 is, it doesn't work when the name of a structured type
1848 (which includes the keyword "struct", etc.) is simply
1850 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
1851 since type specifications in C and Modula-2 are very
1852 different. The C printing of a type is very recursive,
1853 whereas in Modula-2 it is generally very simple. C has
1854 type prefixes and suffixes, which have no real analogue in
1855 Modula-2. Maybe type_print() should call a language
1856 specific type printer. This is also advantageous if we
1857 compile GDB to exclude some of the languages. We'll just
1858 leave those functions out.
1860 Thu Jun 20 16:57:10 EDT 1991
1862 dbxread.c When reading the complete symbol table in (via
1863 psymtab_to_symtab()), the number and types of function
1864 arguments are added to a function type. define_symbol()
1865 calls add_param_to_type() to accomplish this.
1866 Assumption: when we come across a function definition
1867 (N_FUN symbol with an 'f' or 'F' in the name), its
1868 arguments will appear before another function definition.
1869 When a function is found, a pointer to its type is placed
1870 in the global in_function_type. Changes that
1871 add_param_to_type() makes are to this global.
1872 valprint.c The type of a function now includes (for Modula-2) the
1873 types of its parameters.
1874 eval.c Type checking and a check for the proper number of
1875 arguments is now done for function calls. Not sure of the
1876 impact this has on C++ member function yet.
1878 Thu Jun 20 19:58:48 EDT 1991
1880 valprint.c Rewrote the type printer. Broke it into two language
1881 specific parts, adding the functions type_print_m2() and
1883 An unfortunate consequence is this: if you debugging a C
1884 program in Modula-2 mode (why?), info types does not work
1885 well with regular expressions, since the types are printed
1886 out in Modula-2 terminology, but stored in C terminology.
1887 language.[ch] Added the functions new_type_last(), type_keyword(), and
1888 type_sep() to aid in the printing of typedefs.
1889 symtab.c Made the printing of typedefs as language independent as
1890 possible through calls to new_type_last(), type_keyword(),
1893 Fri Jun 21 11:50:26 EDT 1991
1895 dbxread.c Check all incoming ennumerated types. If it looks like
1896 Modula-2's BOOLEAN type, then change the type_code of the
1897 type to TYPE_CODE_BOOL so we can process it as a boolean
1899 valprint.c Replaced some of the 0x%x with calls to sprintf and
1900 hexformat() in val_print().
1901 language.[ch] Added the function hex_to_string(), which converts its
1902 integral argument to a hexadecimal number (format is
1903 language based) and returns the result as a string.
1905 Mon Jun 24 12:25:07 EDT 1991
1907 valprint.c Some functions call type_print_1() directly, instead of
1908 value.h using type_print(), so they can specify where (column) to
1909 print things. Since type_print() takes care of language
1910 dependence, that needs to be called first. Added a
1911 parameter depth to type_print() (so it is now like
1912 type_print_1). Changed type_print to type_print_at, and
1913 made type_print a macro that passes a depth argument of
1915 symmisc.c Changed all calls to type_print_1 to calls to
1917 Makefile.dist Made it possible to build GDB for a specific set of
1918 depend languages. Do this by passing a definition for the macro
1919 LANGS to make. LANGS should be a string containing a
1920 space-separated list of language names (ie. LANGS="c m2").
1921 The default is to build all languages. Note that grammar
1922 files must follow the naming convention of <lang>-exp.y.
1923 gdb.lang This holds the current value of the LANGS macro. It is
1924 examined every time make is called, and is updated if
1926 eval.c Added #ifdef _LANG_<lang> to these files.
1927 expread.c Still need to add them to dbxread.c and coffread.c.
1935 Mon Jun 24 16:33:11 EDT 1991
1937 language.[ch] Added the functions hexformat_pre() and
1938 hex_to_string_pre(), which take a prefix argument to
1939 include in the format string. Thus, hexformat_pre("08") will
1940 return "0x08x" (if the working language is language_c).
1941 Made hexformat() and hex_to_string() calls to the above
1942 with "" as the prefix argument.
1944 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
1945 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,

1952 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
1953 calls to hexformat() and hex_to_string(). Format strings without
1954 the leading "0x" were ignored.
1956 depend Updated to take the above into account.
1959 Tue Jun 25 15:27:18 EDT 1991
1961 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
1962 and type_check_t to keep track of the current state of
1963 range and type checking.
1964 main.c Added the variables range_mode, range_check, type_mode,
1965 and type_check to record the current state of range and
1966 type checking. Added initialization code to main().
1967 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
1968 the above variables.
1971 Tue Jun 25 17:57:08 EDT 1991
1973 dbxread.c process_one_symbol() updates the variable (enum language)
1974 source_lang based on the extension of the filename
1975 contained in the N_SO sybmol that started this symtab.
1976 When end_symtab() is called, the value of source_lang is
1977 put into the language field.
1978 stack.c select_frame() sets working_lang (and possibly type_check
1979 and range_check) to the language field of the symtab
1980 associated with the frame that is selected if working_mode
1981 is language_auto. If working_mode is language_manual, a
1982 warning is printed and working_lang is not set.
1983 language.c Added the function set_type_range(), which sets the value of
1984 type_check and range_check (if their modes call for
1985 automatic setting) based on the current value of
1986 working_lang. A non-zero argument will cause the current
1987 settings to be output.
1990 Wed Jun 26 14:51:40 EDT 1991
1992 eval.c Added range checks on assignment.
1993 m2-exp.y Added the grammar for sets to the language. Currently,
1994 these do not do anything except print an error message.
1996 Wed Jun 26 17:01:04 EDT 1991
1998 m2-exp.y Added the ability for parse_number() to parse negative
1999 numbers. A global flag is set upon encountering a unary
2000 minus. This was done to make, for example, 1 parse as a
2001 CARDINAL, and not as an integer, per Wirth's examples in
2002 Programming in Modula-2 ed.4.
2003 valprint.c Added support for "set radix 2" by then setting
2004 output_format to 't'.
2005 eval.c Implemented range checking on subrange types. Added calls
2006 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
2007 Implemented MIN and MAX for ennumerated types. The
2008 minimum value of an ennumerated type is defined by Wirth
2009 as the first identifier, and the maximum as the last.
2010 m2-exp.y Made octal numbers ending with "B" be characters and those
2011 ending with "C" be numbers, per Wirth's book. (p. 34)
2013 Thu Jun 27 14:11:52 EDT 1991
2015 stack.c select_frame() now only sets working_lang, it does not
2016 notify the user. If working_mode is language_manual, then
2017 a warning is issued once.
2018 main.c At the end of each call to execute_command(), working_lang
2019 is checked against the local static (enum language)
2020 current. If they differ and working_mode is
2021 language_auto, the new settings of language, type and
2022 range checking are printed out.
2023 stack.c Modified frame_info() to include the language of the
2024 current frame in the output of "info frame".
2025 language.[ch] Added the function language_str() which returns the name
2026 of the current language.
2028 Fri Jun 28 15:33:14 EDT 1991
2030 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
2031 the language. INCL and DECL currently cause an error,
2032 since sets are not implemented yet. INC and DEC are
2033 implemented as PREINCREMENT/PREDECREMENT with one
2034 argument, and as ASSIGN_MODIFY with two arguments.
2035 eval.c Added type checking to the above cases.
2036 value.h Added not_lval_constant to the lval_type ennumerated type.
2037 not_lval_constant means that the value is a constant
2038 value; that is 3 or 'a' or TRUE, not as in a constant
2039 identifier. This is used to help coerce numbers such as 3
2040 to either signed or unsigned numbers.
2041 valops.c Added the function value_coerce_constants() which coerces
2042 constant integers as following: if one is a constant and
2043 the other is not, the constant's type is set to the type
2044 of the other argument. If both are constants and one is
2045 signed, the other is converted to a signed constant.
2047 Sat Jun 29 17:26:29 EDT 1991
2049 valarith.c Added a better range checker. It now checks range
2050 (successfully) on integral operations [+-] (signed and
2051 unsigned) for any C sized type. Still does not work well
2052 for multiplication.)
2053 int_in_size() returns an integer that is coerced to fit into
2054 specified number of bytes.
2056 Mon Jul 1 13:04:14 EDT 1991
2058 language.[ch] Added the function binop_result_type(), which returns the
2059 builtin (struct type *) type that would be the result of a
2060 binop on the two values V1 and V2.
2062 Wed Jul 3 19:22:53 EDT 1991
2064 source.c Extended source_info() to include the source language in
2065 the output from "info source".
2067 Fri Jul 5 13:48:52 EDT 1991
2069 utils.c Moved the support functions for the GDB set/show commands
2070 dealing with language into language.c.
2071 language.c Added the function language_info(), which displays info
2072 about the current working language, type and range check
2073 settings. Called via the GDB command "info language".
2074 Added an initialization routine _initialize_language(),
2075 that sets defaults for the language, type and range
2076 variables and sets up the new GDB commands.
2077 main.c Language setup moved to language.c.
2080 Mon Jul 8 10:10:22 EDT 1991
2082 valarith.c Debugged the range checker for arithmetic. Still does not
2083 work for multiplication very well.
2085 Mon Jul 8 12:40:37 EDT 1991
2087 language.[ch] Added the function value_true() which returns non-zero if
2088 its argument represents a boolean true value.
2089 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
2090 check the truth of an expression.
2092 Thu Jul 11 12:51:34 EDT 1991
2094 language.[ch] Added the predicate structured_type(), which returns
2095 non-zero if the argument is a structured type.
2096 Added the predicate pointer_type(), which returns non-zero
2097 if the argument is a pointer type.
2098 eval.c Added the ability to do addition and substraction on
2099 pointers and integers. This case simply bypasses the
2102 Thu Jul 11 14:41:42 EDT 1991
2105 Added the symbol N_DEFD (0x4a) which is a definition
2106 module dependency that is used by the GNU Modula-2
2107 compiler and the linker. It is not important to GDB,
2108 except that [dbx|coff|mips]read.c should ignore these
2111 Fri Jul 12 16:07:00 EDT 1991
2113 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
2114 0 in val_print(). Also added statements to the else part
2115 to coerce type (argument to val_print) to a pointer type
2116 if it is an "array of unspecified length".
2117 valops.c Added the function value_m2_string(), which returns a
2118 (value) value which is a constant string, whose type is
2119 (ARRAY [0..n] OF CHAR). The length field of the type
2120 structure is set to zero, so it will be interpreted as an
2121 "array of unspecified length".
2122 stack.c Moved the language/frame mismatch check to
2123 main.c:execute_command().
2124 main.c The working language is recorded each time
2125 execute_command() is executed. If working lang has
2126 changed during its execution, then the new
2127 language/type/range info is printed out for the user. If
2128 the working language does not match the language of the
2129 frame, a warning is issued.
2131 Sat Jul 13 16:16:39 EDT 1991
2133 eval.c Moved all the type-checking stuff for operators to
2134 language.[ch] language.c. This is so we can keep language-specific
2135 stuff (like for what type operators are defined) in
2137 language.[ch] Added the function binop_type_check(), which checks to see
2138 if its two (value) arguments are type-compatible with its
2139 opcode argument. The opcode should represent an operation
2140 involving an operator. Also added the macro function
2141 unop_type_check, which calls binop_type_check with a
2142 NULL second argument.
2143 expprint.c Added Modula-2 operators to the op_print_tab, so info
2144 expression.h break works correctly. Also added "op_string", which
2145 returns the string corresponding to the (enum exp_opcode)
2146 opcode that is its argument.
2149 Sat Jul 13 18:26:18 EDT 1991
2151 coffread.c Added code to record the type of function arguments with
2152 each paricular function. Code is very similar to that
2154 dbxread.c Moved add_param_to_type() to symtab.c
2155 symtab.[ch] Added function add_param_to_type() from dbxread.c
2157 *** NOTE: The above additions have not been tested.
2159 Mon Jul 15 12:50:47 EDT 1991
2161 langauge.[ch] Added the functions type_error and range_error, which work
2162 like error() except if the type/range mode is set to
2163 *_mode_warn, then they do not do a return_to_top_level(),
2164 but merely print a warning.
2165 Also changed [set|show]_[type|range]_command() to support
2166 the new "warn" feature.
2168 Thu Jul 18 17:50:54 EDT 1991
2170 mipsread.c Added code to record the type of function arguments with
2171 each particular function. Code is very similar to that
2174 *** NOTE: The above additions have not been tested.
2176 Fri Jul 19 11:19:10 EDT 1991
2178 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
2179 UMIN_OF_SIZE, which when given a size of a numeric type,
2180 return the maximum and minimum value it can hold. UMAX...
2181 and UMIN... return the result for unsigned types.
2182 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
2183 struct types. They call above macros.
2184 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
2185 avoid a name conlict with the above.
2186 c-exp.y Added range checking on numeric constants in
2187 parse_number() for completeness.
2188 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
2189 return 0 if working_lang is not language_c.
2191 Thu Aug 8 14:17:22 EDT 1991
2195 breakpoint.c Documentation strings of some commands changed to
2196 eliminate the references to the C language where
2199 Tue Aug 13 15:48:03 EDT 1991
2201 m2-exp.y Added qualified identifiers to the grammar. The semantics
2202 are slightly different from those of the GDB operator ::
2204 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
2205 type_exp, where type_exp is any valid type expression.
2207 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
2208 printcmd.c Modified ptype_command() so it actually parses the input
2209 (necessary for type expressions with scope qualifiers).
2210 Added the function ptype_eval() which expects an
2211 expression composed of one OP_TYPE element.
2212 *.[ch] Replaced all occurences of parse_c_expression with
2214 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
2216 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
2218 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
2220 Small fixes from Peter Schauer:
2222 * infrun.c (child_attach): Lint.
2223 * solib.c (find_solib): Handle shared libs version 2.
2225 Small fixes from David Wood:
2227 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
2231 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
2232 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
2234 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
2235 chars_per_line is at maximum (user typed `set width 0'). Fix
2236 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
2238 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
2240 * coredep.c: include ptrace.h where necessary.
2241 * mipsread.c(parse_lines): fix unsigned char problem that was
2242 messing up line numbers on SGI's and possibly other MIPS based
2244 * infrun.c (child_create_inferior): use better test to check
2245 return val from setpgrp().
2246 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
2247 for sgi/irix support.
2249 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
2251 * mipsread.c (parse_symbol): Put non-static procedures
2252 in the global block.
2254 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
2256 Patch together `text_start' and `text_end' for 29K port.
2258 * exec.c (exec_command): If NEED_TEXT_START_END, define the
2259 variables and set them based on the exec file.
2260 * am29k-tdep.c: declare text_start.
2261 * valops.c (call_function_by_hand): declare text_end.
2263 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
2264 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
2265 because machines that do this will also have to know to
2266 set NEED_TEXT_START_END. Besides, it was a redundant way to
2268 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
2269 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
2270 NEED_TEXT_START_END.
2272 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
2274 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
2276 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
2277 Pass MUNCH_DEFINE to munch whenever we run it.
2278 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
2279 format string; use 0x%x instead.
2280 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
2281 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
2282 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
2283 * inflow.c: Handle `short' process group IDs.
2284 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
2285 and check for ptrace errors.
2286 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
2287 (coff_symfile_init): Initialize text_bfd_scnum.
2288 (read_coff_symtab): Use it to find the text [and absolute?] sections.
2289 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
2290 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
2291 Merge target arm case with other "easy" cases. Add target
2292 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
2293 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
2295 * minimon.h, remote-adapt.c, remote-mm.c: Add.
2296 * munch: Cope with RT/PC putting fns in data segment.
2297 Restore ability to override `nm' by specifying MUNCH_NM.
2298 * xconfig/rtbsd, xconfig/ultra3: New host systems.
2299 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
2300 and remote-adapt. Remove encapsulated coff #define's (the
2301 support should go in BFD, and gdb shouldn't know or care).
2302 * tconfig/a29k-kern: Same, but for remote kernel debugging.
2303 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
2304 * tm-29k.h: Update BADMAG (though it should go away).
2305 Allow the register definitions to be overridden in another
2306 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
2307 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
2308 DUMMY_SAVE_GR96, for handling kernel calling conventions
2309 that use GR64+ rather than GR96+.
2310 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
2311 remote debugging of Ultra3 kernel. Includes tm-29k.h and
2312 overrides various things.
2314 * remote-mm.c (mm_attach, mm_wait): Handle attach like
2315 child_attach does, making a clean stop in the newly attached
2317 * remote-eb.c: Lint.
2319 * coffread.c: Make coffread independent of any particular
2320 variant of COFF. Avoid #include-ing any particular one except
2321 internalcoff.h. BFD now passes key values for symbol reading
2322 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
2323 and the symbol masks and shifts); use them.
2324 Remove obsolete end_of_text_addr.
2326 * exec.c: Remove unused include files.
2328 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
2330 * Makefile.in (documentation targets): Pass $(M4).
2331 Bugfix from eggert@twinsun.com (Paul Eggert).
2333 * stack.c (down_silently_command): Check for stack existence.
2335 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2337 * Makefile.in (VERSION): Update to 4.0.3.
2339 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
2341 * core.c (core_file_command): Print frame at coredump with
2342 its level number, by calling print_stack_frame.
2343 * frame.h: Add selected_frame_level, print_stack_frame.
2344 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
2345 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
2346 Change print_sel_frame and print_selected_frame callers to
2349 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
2350 * symfile.c (free_named_symtabs): Ditto.
2351 * main.c (main): wrap_here needs an arg.
2352 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
2353 (solib_add): Avoid noise.
2354 (solib_create_inferior_hook): Lint.
2355 (sharedlibrary_command): Move dont_repeat to here.
2356 * utils.c (error): Call wrap_here to force buffered output.
2358 Small patches from Peter Schauer:
2360 * coffread.c (start_symtab): Free any existing line_vector before
2362 (read_coff_symtab): Ditto for type_vector.
2364 * source.c (lines_to_list): New variable, replacing function.
2365 (all uses): Use as variable.
2366 (_initialize_source): Add 'set listsize' and 'show listsize'.
2367 * utils.c (lines_to_list): Remove function.
2368 * stack.c (print_frame_info): Use as variable.
2369 * defs.h (lines_to_list): Remove declaration.
2371 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2373 * breakpoint.c (insert_breakpoints): Restore warning about
2374 the program might be running in another process, but only for
2375 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
2376 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
2378 * utils.c (error): if error_pre_print is set, print the string
2380 * main.c (main, print_gnu_advertisement, print_gdb_version):
2381 Reformat legalese so it always prints, but acts as an "I'm here"
2382 message while symbols are being read. If any errors occur,
2383 print a few newlines to set off the message and start it at the
2384 left margin. Remove mention of "help" command, and don't yak
2385 about symbol reading.
2386 (catch_errors): Error string is now printed first in case of
2388 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
2389 suggest the "help" command.
2391 * Makefile.in (VERSION): Set to 4.0.2.
2393 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
2395 * .gdbinit: Remove useless "rr" command. Set complaints
2396 to 1 for people debugging gdb.
2398 * breakpoint.c, remote-vx.c: Reword strings printed by
2399 catch_errors callers.
2401 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
2403 * WHATS.NEW: "history write -> history save". Doc "write on/off".
2404 (Fix from kenc@viewlogic.com.)
2406 Fix some infrastructure to be able to cope with host and target
2407 machines with different sized basic types (ints, ptrs, etc).
2408 (Idea from pierre@la.tce.com (Pierre Willard).)
2410 * values.c (value_from_longest): Rename from value_from_long.
2411 Handle pointer types as well as integers, so that targets with
2412 different pointer sizes from the host can be accomodated.
2413 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
2414 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
2415 uses of value_from_long to value_from_longest.
2416 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
2417 the correct pointer type to value_from_long{est}.
2419 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
2421 * remote-vx.c: Remove obsolete code for calling functions via
2422 vxworks kludge interface (it referenced value_from_long).
2424 * valops.c (value_string): Find malloc with lookup_misc_func, not
2427 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2429 Make writing to files work properly. (Fixes to BFD are also needed.)
2431 * core.c (core_open): Open file ourselves, read or r/w, depending on
2432 write_files. Use bfd_fdopenr.
2433 * gdbcore.h (write_files): New variable.
2434 * exec.c (write_files): Define variable, add set&show for it.
2435 (exec_file_command): Use write_files to open for read or r/write.
2437 Make shared library reading happen automatically. These changes
2438 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
2440 * inferior.h (stop_soon_quietly): Add to exported variables.
2441 * infrun.c (child_create_inferior): call solib hook, if defined.
2442 (child_attach): call solib hook, if defined.
2443 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
2444 (find_solib): Use lookup_misc_func rather than hand-rolled.
2445 (symbol_add_stub): New stub for catch_errors.
2446 (solib_add): Avoid output if !from_tty. Catch errors rather
2447 than just calling symbol_file_add and bombing.
2448 (solib_create_inferior_hook): Interface with the target process
2449 to let it read and alloc shared libs, then figure out what it did.
2451 * core.c (validate_files): Fix typo, soften warning.
2452 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
2454 * utils.c (fputs_demangled): Avoid duplicate printing if
2455 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
2457 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
2458 (Fix from pierre@la.tce.com (Pierre Willard).)
2460 * main.c (catch_errors): Change argument to a char * from an int,
2461 since a char * can point to a struct full of glop, but an int
2462 is not guaranteed to be able to hold a pointer.
2463 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
2464 breakpoint_re_set_one, breakpoint_re_set): Adapt.
2465 * core.c (core_open, solib_add_stub): Adapt.
2466 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
2468 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2470 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
2471 by adding .NOEXPORT target.
2473 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
2477 * Makefile.in (VERSION): Roll to 4.0.
2478 (gdb.tar.Z): Make refcard.ps as well, for shipment.
2480 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2482 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
2485 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
2488 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
2490 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
2491 reflect above name change
2493 * WHATS.NEW: correct pointer to refcard.
2495 * doc/gdb.texinfo: update New Features, Installing
2497 * doc/gdbint.texinfo: add short description of configure +template
2499 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2501 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
2503 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
2505 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
2506 tar file, add dependencies for referenced doc files.
2508 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
2510 * coffread.c, symfile.c, stack.c: saberized.
2512 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2514 * doc/refcard.tex: permuted Essential Commands sec
2516 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
2518 set/show symbol-reloading
2519 default set complaints 0
2521 RET-repeat disabled after prompted long displays
2522 processID (attach) interpretation of 2nd GDB cmdline arg
2524 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
2526 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
2527 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
2528 breakpoint.c, main.c: lint.
2530 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2532 Install new configuration scheme for GDB and friends.
2534 * config.sub: Translate ordinary names to three-part names.
2535 * configure: Use three-part names internally.
2536 * configure.in: Translate three-part names to filenames.
2538 * README, WHATS.NEW: Update for gdb-4.0.
2539 * Makefile.in: Roll VERSION to 3.99.
2541 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
2543 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
2544 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
2545 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
2546 to single structures rather than arrays; when passing
2547 their address, use &. This avoids trouble with bdead compilers.
2548 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
2549 instead. This avoids portability headaches.
2550 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
2552 * source.c (open_source_file): Avoid ANSI const bdeath by
2553 skipping declaration and then casting result value.
2554 * tm-hp300bsd.h: Clarify comment.
2555 * utils.c (strstr): Result is const char *; ANSI bdeath.
2556 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
2557 since system include file defines it differently from "defs.h",
2558 though the two are equivalent for our purposes.
2559 * tconfig/hp300bsd: Add m68k-tdep.o.
2561 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
2563 * tconfig/sun*4: Remove warnings about system assembler.
2565 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2567 * mcheck.c: Avoid warning about undeclared abort fn.
2568 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
2569 it causes recursive calls to error() when used in cleanups.
2570 To do so requires that we make it a function, so we do.
2571 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
2572 * utils.c (do_cleanups): Remove the current cleanup from the
2573 chain *before* calling it, in case error() is called from it.
2574 The result won't be pretty, but won't be an infinite loop either.
2576 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
2578 * dbxread.c (read_struct_type): Grok anon structs for C++.
2579 (vb_name, vptr_name): Null terminate these strings.
2581 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
2583 Minor bug fixes from BSD Net2 gdb:
2585 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
2586 returns 0, there is no previous frame.
2587 * breakpoint.c (commands_command): If !from_tty, don't call
2588 input_from_terminal_p().
2589 * dbxread.c (record_misc_function): Speed up slightly.
2590 (compare_psymbols): Ditto.
2591 * infcmd.c (do_registers_info): Take a second argument to
2592 determine whether to print float registers. "info registers"
2593 does not do so anymore. "info all-registers" does, now.
2594 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
2596 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
2597 * inflow.c (initialize_inflow): Set tflags_ours correctly.
2601 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
2602 executing_breakpoint_commands if we are interrupted by error.
2603 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
2604 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
2605 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
2606 catch_errors() so we can setup the frame regardless of whether
2607 the shared libs work.
2608 * ieee-float.c (double_to_ieee_extended): Get exponent from
2609 right place in little-endian systems. From John Carey.
2611 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2613 * main.c: Remove unused terminating_signals and catch_termination().
2614 (long_options): Terminate with a zero element.
2615 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
2616 (gdb_readline): Make call-compatible with readline.
2617 (init_signals): Improve comments re vfork vs. signal.
2619 * utils.c (prompt_for_continue): Use new gdb_readline().
2620 If we prompt for continuation, we don't let CR repeat the previous
2621 command, once we get back to a prompt. It's too easy to keep
2622 hitting CR, expecting "--more--" prompts, and have some long
2623 command start repeating on you.
2625 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
2627 * blockframe.c (frameless_look_for_prologue): Speed up by
2628 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
2629 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
2630 Define two variants, one faster.
2631 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
2632 and return zero, rather than giving an error.
2633 (setup_arbitrary_frame): Initialize the PC in the new frame.
2634 (skip_prologue): Add a second arg saying whether we're just
2635 checking for a frameless function or not.
2637 * core.c (core_open, core_close, core_xfer_memory): Move
2638 section table pointers and bfd* into the target_ops.
2639 (core_open): Allow errors in shared lib reading, etc.
2640 (core_files_info): Describe shared library sections.
2642 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
2643 exec_files_info, set_section_command): Move section table
2644 pointers and bfd* into the target_ops.
2645 (add_to_section_table): Add BFD to section table.
2647 * target.c (target_xfer_memory, target_info): Pass target to
2648 xfer_memory and target_info functions.
2651 * gdbcore.h: Move struct section_table.
2652 * target.h: New home of struct section_table.
2654 * solib.c (solib_add): New argument is the target_ops whose
2655 section list is to be added to, if any. Reallocate the
2656 sections in that target to add any that come from shared libs.
2657 (throughout) so_sections renamed to sections.
2658 (solib_xfer_memory): Deleted.
2659 * tm-sunos.h (SOLIB_ADD): Add target argument.
2660 (SOLIB_XFER_MEMORY): Delete.
2662 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2663 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
2664 from target_ops. It's the same on all targets. Add two section
2665 pointers to target_ops.
2667 * stack.c (find_relative_frame): Dump ancient algorithm for
2668 "down", just use handy "next" pointers.
2669 (frame_command): Don't error if there is no stack; let user
2672 * inflow.c (new_tty_prefork, new_tty): New prefork routine
2673 modifies static state in the parent process; new_tty itself
2674 runs in the child and modifies the child's file descriptors
2675 to match the saved static state.
2676 * infrun.c (child_create_inferior): Call new_tty_prefork,
2679 * infptrace.c (child_xfer_memory): Add ignored target arg.
2680 * remote-eb.c (eb_xfer_inferior_memory): ''
2681 * remote-nindy.c (nindy_xfer_inferior_memory): ''
2682 * remote-vx.c (vx_xfer_memory): ''
2683 * remote.c (remote_xfer_memory): ''. Rename from
2684 remote_xfer_inferior_memory.
2686 * main.c (main): Only try to attach "corefile" argument if
2687 it starts with a digit.
2689 * symfile.c (symbol_reloading): New "set/show" variable.
2690 (symbol_file_add): Shorten message about symbol reading.
2691 (add_symbol_file_command): Merge with add_syms_addr_command,
2692 since this should work on all targets now.
2693 (stop_whining): Default to zero, to shut up complaints
2694 about bad symbol tables on many systems.
2695 (free_named_symtabs): Just exit unless symbol_reloading.
2697 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
2698 and add comment explaining shared library screw.
2700 * source.c: #if defined => #ifdef.
2702 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2704 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
2706 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2708 * doc/rdl-apps.texinfo: provide default readline-appendix finder
2709 (doc/Makefile knows how to make one for local config)
2711 * Makefile.in: use doc/Makefile for doc targets
2713 * doc/Makefile: GDB documentation now has its own Makefile
2714 doc/refcard.tex: renamed from "gdbrc.tex"
2715 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
2716 doc/gdbint.texinfo: add markup in "Cleanups" chapter
2719 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2721 * values.c (baseclass_addr): When reading target memory, use the
2722 length of the basetype, not the upper type. We've only malloc'd
2723 enough space for the basetype, leading to errors in free().
2725 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
2726 ends up as a function specially, since we know the actual type of
2727 the pointed-to address. This (somewhat) fixes display of
2728 expressions that include misc_function_vector names. Try `cond 1
2729 !strcmp("a","b")' then `i b'.
2731 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
2732 The child can be proceeded from inside wait_for_inferior in
2733 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
2734 getting skipped in that case.
2736 * expprint.c (print_subexp): Use filtered output, since the
2737 subroutines we call use it, otherwise the output is horribly
2738 mangled, since output of wrappable stuff comes out late.
2740 * Makefile.in: Bump VERSION to 3.98.1
2742 * infrun.c (child_create_process): Use execlp to find the
2743 shell to exec our target program. This requires some fiddling
2744 with `environ' since there is no execlpe().
2746 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
2748 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
2749 Minor rearrangement of refcard permits two new make targets--
2750 gdbrc.dvi DVI output for refcard, using CM fonts
2751 gdbrc.ps PostScript refcard, using PS fonts
2753 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2757 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
2758 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
2760 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2762 * doc/gdb.texinfo: last changes for release.
2763 Minor typo and formatting fixes; incorporated most fixes remaining from
2764 filed mail commenting on earlier drafts.
2766 Added warnings: pipes don't work in run command;
2767 conditions are converse of assertions;
2768 step over fn without debug info goes to next fn;
2769 vars may have "wrong" values near fn entrance, exit
2771 Added example from Kingston on printing repeated nonadjacent values
2773 Added explicit mention that in Emacs gdb mode C-c and C-z are like
2774 shell mode for signals
2776 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
2777 doesn't sound so much like its parent "Stopping and Continuing"; also
2778 moved entries on continue to top of section, so they don't get lost.
2780 Improved installation directions in appendix, added manual formatting
2783 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2785 * configure.in: Remove xm.h and tm.h even if we aren't linking
2786 new ones, so "./configure sun4; ./configure none" does the right
2787 thing. Assume that alldeps.mak and depend are already built in
2788 srcdir, and avoid running "make" (particularly "make depend",
2789 which involves "gcc") from inside configure. Build Makefile
2790 directly rather than building Makefile.conf first.
2791 * configure: Regenerate with above changes.
2792 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
2793 to 3.98. Revise gdb.tar.Z procedure to produce a file
2794 called gdb-$(VERSION).tar.Z but which unpacks into a
2795 directory called "gdb". Move non-source files out of
2796 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
2797 (depend): Don't try to do "gcc expread.y".
2798 (expread.o): Update dependencies by hand.
2800 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2803 Fixed a variety of small typos that prevented info from formatting
2804 cleanly; altered too-long heading for GPL Appendix, as discussed
2805 w/RMS; Changed date on cover to July 91.
2807 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2810 (1) Applied some fixes due to comments from Larry Breed (easier ones
2811 through chapsec 5.2)
2812 (2) Eliminated use of @footnote---had my doubts about it anyways, and
2813 it's broken in latest texinfo
2814 (3) Introduced *some* use of [] for optional arguments, where
2815 explanation is not simpler by listing cmd w arg and cmd w/out arg
2816 separately. Still not using @deffn.
2817 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
2818 couple of headings are too long. Need patches to texinfo or revision
2821 * Partial update to README (which still needs work for this
2822 release!): (1) use of configure corrected for new script,
2823 (2) "make gdb.dvi" and "make gdb.info" mentioned.
2825 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
2827 * symtab.c (lookup_symbol): Don't complain right off about
2828 no debug symbols; use the misc function vector first.
2829 (list_symbols): Use misc function vector to find symbols
2830 that don't have debug info, and print them.
2831 (find_pc_symtab): Temporarily avoid fatal() when psymtab
2832 PC range doesn't match symtab PC range, as it does on the
2833 MIPS because our symtab reading isn't perfect.
2835 * dbxread.c (dbx_symfile_read): Make warning about
2836 "no debug symbols" slightly nicer.
2838 * source.c (select_source_symtab): If "main" symbol exists,
2839 but decode_line_spec can't find line info, don't just return
2840 a zero; try other source symtabs or give an error.
2842 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
2843 their low addresses first, then rip through fixing high addrs.
2845 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
2846 <runene@ifi.uio.no>.
2847 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
2849 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
2851 * Minor, mostly mechanical, cleanup of doc subdir for clean
2852 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
2853 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
2855 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
2857 Mostly MIPS and general symbol-reading fixups.
2859 * doc/gdbint.texinfo: Add documentation on symbol-reading
2862 * mipsread.c: Remove kludges around #include "ecoff.h".
2863 Remove redefinitions of a_magic, etc, no longer used.
2864 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
2865 Fix global overview comments to match symfile.c protocol.
2866 (mipscoff_new_init): Eliminate cur_hdr if we have one.
2867 (mipscoff_symfile_read): Eliminate unused code. Avoid
2868 sorting all the symtabs, when all we have read here is psymtabs.
2869 The symtabs are sorted as they are created anyway. Tell
2870 condense_misc_bunches whether we're mainline.
2871 (psymtab_to_symtab_1): Pass filename when recursing, to make
2872 stack trace more informative.
2873 (parse_partial_symbols): Assume cur_hdr as argument.
2874 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
2875 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
2876 the TYPE_NAME of char *, since that's done in symfile.c.
2877 (free_numargs, parse_symbol, add_symbol, add_block,
2878 shrink_linetable): Declare these fns void.
2879 (upgrade_type): Convert tree of if's to switch. Clean up
2880 bogus "off == 0" handling with a complaint. Avoid setting
2881 field bitpos and bitsize of array with lower and upper bounds.
2882 Check specified bitsize of elements against their actual type's
2883 bitsize, and complain if different. Complain about unknown
2885 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
2886 (psymtab_to_symtab_1): Print names of subsidiary files that
2887 are being read in. FIXME, we read far too many files. This code
2888 is not the problem, the problem is in parse_fdr where the psymtabs
2890 (cross_ref): Result should indicate that we used one aux entry
2891 normally, or two if we encountered a "next" entry. This used
2892 to leave the caller pointing at the wrong aux entry.
2893 (add_symbol): If overflowed cur_block, reallocate it larger,
2894 chase all pointers to it, and complain(), rather than clobber memory.
2895 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
2896 (new_field): Only allocate one field initially, not two.
2897 Pull ++ out of macro argument. Simplify.
2898 (_initialize_mipsread): Avoid initialization of importd
2899 global_psymbols and static_psymbols.
2901 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
2902 to properly set pst->symtab; avoid searching for it.
2903 (symfile_fns): Improve comments, add a FIXME.
2904 * dbxread.c: Update comments to reflect symfile protocol.
2905 (read_ofile_symtab, end_symtab): Return the symtab.
2906 (psymtab_to_symtab_1): Set pst->symtab.
2908 * coffread.c (coff_symfile_read): tell condense_misc_bunches
2909 whether we're mainline.
2911 * symfile.h (sym_fns): Remove unused sym_discard member.
2912 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
2914 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
2915 the environment variable is not.
2916 * infcmd.c (finish_command): Use filtered printfs.
2917 * cplus-dem.c: Add struct tags to a few unnamed structs.
2918 * valops.c (value_coerce_array): Improve comments.
2919 * valprint.c (type_print_varspec_suffix): Print array size only
2920 if greater than zero.
2921 * m88k-tdep.c: Shift some lines left by one space, that had
2922 apparently been trashed at some point.
2923 * TODO: More things to do, a few got done.
2925 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
2927 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
2928 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
2930 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
2931 * expread.y, findvar.c, symmisc.c: Ditto.
2932 * printcmd.c (address_info): Update printed forms of LOC_
2933 symbols. Elim LOC_EXTERNAL.
2934 (print_frame_args): Keep track of param stack offsets before
2935 re-looking up to find the local register param is kept in.
2937 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
2938 Further integration of mipsread into gdb. Eliminate unused
2939 routines, duplicate declarations. Handle static symbols in
2940 psymtabs as well as external symbols. When reading symtabs,
2941 insert symbols into the correct block (global, static, or a local
2943 (read_mips_symtab, parse_partial_symbols): Don't pass useless
2945 (mipscoff_symfile_read): Don't call select_source_symtab.
2946 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
2947 rather than SYMBOL_VALUE.
2948 (parse_external): Comment clobbering of top_stack.
2949 (parse_partial_symbols): Update comments. Allocate and parse
2950 static symbols as well as external symbols. FIXME, enum values
2951 are not handled in this pass, but should be. Inline new_psymbol.
2952 Use SYMBOL_VALUE_ADDRESS.
2953 (psymtab_to_symtab_1): Read symbols into global static block
2954 by default (until enter some function's local block context).
2955 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
2956 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
2958 * source.c (select_source_symtab): Select a source symtab
2959 from either the symtabs or, failing that, the psymtabs.
2960 (list_command): Update error message.
2961 (forward_search_command, reverse_search_command): Use getc, not
2962 fgetc, for speed. FIXME, add comment about buffers that die if
2963 overrun by long line.
2965 * values.c (unpack_field_as_long, modify_field): Avoid shifting
2966 by an entire word, which is not portable, if we have a 32-bit
2967 field. (Code in dbxread.c already turns such bitfields, if
2968 aligned, into ordinary ints, but fixing this will help for other
2969 symbol formats and for future changes.)
2970 * core.c (core_open): Handle ANSI const brain death.
2971 * utils.c (vprintf): Fix varargs typo.
2973 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
2975 * findvar.c (find_var_value): Handle &function better.
2976 * TODO: Document work needed on &fn and &array.
2977 * printcmd.c (print_address_symbolic): New arg is the prefix
2978 to print if a name is printed.
2979 (print_address_demangle): Honor "set print address" now.
2980 Use new arg above to improve spacing of output.
2981 * valprint.c (val_print): When printing function pointers,
2982 print symbolic form too.
2983 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
2985 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2987 * core.c (memory_error): Reword error msg to mislead less.
2989 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
2991 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
2992 parse_partial_symbols): Use newer BFD internals (external_filehdr
2993 and external_aouthdr), byte-swap the fields that we care about
2994 before using them, and make the file header data local to
2995 read_the_mips_symtab rather than global.
2997 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
2999 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
3000 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
3002 * main.c (command_line_input): Flush stdout and stderr
3003 before every call to readline. This reportedly fixes a bug
3004 that comes up in Sys V running emacs-gdb and/or xxgdb,
3005 when stdin/out are pipes or sockets.
3007 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
3009 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
3010 Avoid declaring Makefile dependencies, because GNU Make stupidly
3011 tries to update it if we do.
3013 * coffread.c: Revise for minor changes to bfd internal coff
3016 * configure: If -template= is given a relative path, make it
3017 absolute before recurring in subdirectories.
3019 * configure, configure.in, Makefile.in: Install "configure" script
3020 as replacement for config.gdb.
3021 * config.gdb, Makefile.dist, Makefile.sdir: Remove
3022 * README: Update for configure, mostly. FIXME.
3024 * Add dec3100 as equivalent to littlemips. Indicate in all host &
3025 target config files that they are for the host. When the lines
3026 get copied into the Makefile, this makes it more obvious what's
3029 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3031 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
3032 tabs, which end up in the disassembler output inadvertently.
3034 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
3036 Make it compile cleanly in an ANSI GCC2 environment.
3038 * blockframe.c: <stdio.h>
3039 * cplus-dem.c: free takes a void *, ifdef __STDC__
3040 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
3042 * defs.h (alloca): Avoid doing anything if alloca already def'd.
3043 * stddef.h, stdlib.h: Remove these files.
3044 * symtab.c: Avoid declaring qsort, close.
3045 * symfile.c: Avoid declaring close.
3046 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
3047 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
3049 Assorted other changes.
3050 * dbxread.c: include "libaout.h", not "liba.out.h".
3051 * printcmd.c (print_frame_args): Set recurse properly for
3052 indentation of struct and array parameters.
3053 * valops.c (value_cast): Allow cast to void.
3054 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
3055 single_step() in a target-independent fashion.
3056 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
3057 set up to be ready to continue. This makes us target independent.
3058 * infptrace.c (child_resume): Remove call to single_step; now
3059 can single step a SPARC target of any kind.
3061 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3063 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
3064 docn into separate sections---basically chapters, plus two loose
3065 pieces that can be configured to go in different places. This
3066 allows GNU m4 to preprocess the manual without coredumping.
3068 * Makefile.dist: tell TeX where to find texinfo.
3070 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3072 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
3073 the new target "rdl-apps.texinfo" which captures the Makefile
3074 variable that records where to find the Readline libraries.
3076 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
3078 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
3079 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
3080 * defs.h (const, volatile): Only define if not already defined.
3081 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
3083 * README: Update for release 3.95.
3084 * config.gdb: Don't create readline dir in subdir builds.
3085 * main.c: Include with "..." form for non-system include files,
3086 so "gcc -MM" for "make depend" works.
3087 Include readline files with "...h" rather than <readline/...h>.
3088 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
3090 * coffread.c: Undo minor damage done by Rich Pixley. Use
3091 different internal and external representations of COFF
3092 data structures. Use new BFD routines for swapping them in and
3094 * symfile.c (free_named_symtabs): Avoid freeing file names that
3095 are null or empty. Old i960 tools seem to produce files that
3096 claim to have empty names, causing each successive file read
3097 to blow away the previous one.
3098 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
3099 Move deferred_stores to top of file, but don't separate its
3100 #define's from its variable. Add commentary.
3101 * Makefile.dist: Fix Rich damage; undo "configure" changes in
3102 favor of keeping the (working) config.gdb. Move readline
3105 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
3107 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
3109 * infptrace.c (fetch_registers): no result, since now void.
3110 * tconfig/news: target depends on m68k-tdep too.
3112 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3114 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
3117 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
3118 applied various small fixes due to or inspired by RMS comments
3120 * doc/gdb.texinfo: finished using all RMS comments, save those for
3121 appendices on readline and cmd history (which are in other source
3124 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3126 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
3127 chapter 9; (2) documented 'break' command's menu mode for
3128 overloaded names, in response to hgs problem report C++ p-31
3130 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
3132 * doc/gdb.texinfo: (1) better introductory example; (2) more
3133 consistent use of @code, @samp, @file, @kbd throughout; small
3134 cleanups to first three nodes; (3) new "Contributors" node;
3135 (4) Appendix, Renamed Commands; (5) divert specialized startup
3136 instructions to "Targets" chapter for generic manuals, while
3137 leaving them up front for manuals specific to specialized
3138 environments; (6) apply fixes from RMS comments through chapter 4.
3140 * pretex.m4: modify explanatory text slightly (and redefine
3141 "regexp") to keep GNU m4 from complaining. (It still crashes
3142 later, but one step at a time...)
3144 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
3146 * readline/readline.c (update_line): Avoid dereferencing a pointer
3147 before comparing it to its bounds. Saber caught this.
3148 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
3149 and only set PC if tgetstr returned non-null. Saber caught this.
3151 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3153 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
3154 stuff for config manual) here where it counts; updated
3155 to use new subdir structure (gdb/doc/).
3157 * Makefile: generated from above via
3161 * gdbint.texinfo: added instructions on generating gdb.info* files
3162 locally for release. These are ordinary info
3163 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
3164 Makefile)---but due to use of texinfo 2, can't count on makeinfo
3165 to generate these, so we distribute them already formatted.
3167 * gdb.texinfo: included full Info node and menu crud (as generated
3168 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
3170 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
3171 put in comments-for-future gdb.info target (one day makeinfo will
3174 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3176 * gdb.texinfo: Updated to include new or old undocumented
3177 commands, at least the following (perhaps some others I forgot to
3178 record): info f, info float, info path, info program, info s, info
3179 set, info source, info terminal, info types, info user, set/show
3181 Also covered all recent GDB command renames for v4.
3183 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
3185 * mipsread.c: Rather than keeping count of how many symtabs
3186 and psymtabs we have, for sorting purposes, count them when
3187 we need to sort. This fixes bug in rereading of symbol tables.
3189 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
3191 * infcmd.c: renamed "info path" to "show paths"

3202 Fix up "saber_gdb" to work again.
3203 * saber.suppress: Update.
3205 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
3206 symtab.h, target.c, target.h: Lint.
3207 * core.c: setup and select frame after reading shared libs,
3208 else reading shared libs will clobber them. Lint.
3209 * utils.c (error): Force out any buffered wrap text.
3211 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
3213 * remote.c: Remove decls of memory_insert_breakpoint
3214 and memory_remove_breakpoint, no longer used. (Suggestion of
3217 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
3218 to make it easier to interface to "configure"'d libraries.
3220 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
3222 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
3223 aliases for set/show print.

3275 dc_dcontext_t not int.
3277 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
3279 * coffread.c [TDESC]: Move setting of debug_info from
3280 coff_symfile_read to find_linenos and make it work with BFD.
3282 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
3284 * signame.c: Cast const char* to char* when assigning to sys_siglist.
3286 * utils.c (strsave): Make arg const char* not char*.
3288 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

3309 Mips bringup and general cleanup
3311 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
3312 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
3313 (This still doesn't seem to make MIPS bkpts work.)
3314 * mipsread.c: Remove dup "Reading symbol data..." msg.
3315 (symbol_file_command, add_file_command): Remove, obsol.
3316 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
3317 Wrap output appropriately.

3319 selected_frame rather than target_has_stack or coredumping.
3320 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
3321 enums appropriately.
3323 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3327 * cplus-dem.c: Include defs.h and param.h.
3328 Makefile.dist: Don't hack in the "param.h".
3329 param.h: Don't include defs.h.
3331 * expread.y: Use a union to deal with the fact that type_stack
3332 can have both ints and enum type_pieces in it.
3333 ({push,pop}_type_int): New functions.
3335 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

3347 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
3348 copying.awk, solib.c, inflow.c, symmisc.c
3349 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
3350 Use {value_as,unpack}_pointer (added to values.c)
3351 not {value_as,unpack}_long on CORE_ADDR's.
3352 Use longest_to_int (added to defs.h) instead of cast to int.
3353 Remove from_tty arg to mod_path.
3354 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
3355 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

3843 * i386-pinsn.c: Move #includes to top, remove useless ones.
3844 * i386-tdep.c: Don't bother including <.../reg.h> since we
3845 don't use it (and it doesn't exist on host systems).
3847 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
3848 Convert negative numbers properly.
3849 (ieee_test): Make numbers really random; fix format arg.
3851 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
3852 * core.c (core_detach): Unpush core_ops, which might not be on
3853 top. We used to just pop the top, which broke things. Don't
3854 need dont_repeat() any more.
3855 (core_file_command): Psst! Don't repeat it.
3856 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
3857 * expprint.c (print_subexp): Avoid switch fallthru on
3858 BINOP_ASSIGN_MODIFY, so we can print += and such.
3859 * frame.h: Fix typo.
3860 * inflow.c (kill_command): After killing inferior, print our
3861 current frame in the core file, if we have one.
3862 (generic_mourn_inferior): When inferior dies, either select
3863 the current frame (in the new target, e.g. core file), or
3864 set both the current and selected frames to NULL.
3866 Changes from Peter Schauer.
3868 * infptrace.c: Avoid <sys/ptrace.h> on USG.
3870 * Make all file names fit in 14 characters (sigh and damn!):
3871 mv hp300hpux-xdep.c hp300ux-xdep.c

3879 mv remote-sa.m68k.shar rem-m68k.shar
3880 mv remote-multi.shar rem-multi.shar
3881 * Makefile.dist, README, config.gdb, convex-pinsn.c,
3882 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
3883 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
3886 * command.c (user_info_1, user_info): New command for listing
3887 the user-defined commands.
3889 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
3891 * dbxread.c (really_free_pendings): Clear file_symbols
3892 and global_symbols after freeing them; otherwise, running
3893 this function twice (if it appears twice on the cleanup
3894 chain), we try to free things twice.
3896 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
3897 based on text_addr (the address of text in core), not on addr (the
3898 offset between text in the .o file and in core). This change
3899 is from Peter Schauer.
3901 * main.c: Define ALL_CLEANUPS as a cast of zero.
3902 (return_to_top_level): Use it.
3903 (main): Do all cleanups after each command run as part
3904 of the gdb startup sequence. Also do all cleanups before
3905 entering the command loop, and every time we exit the command
3906 loop and reenter. Before, the cleanups from the startup sequence
3907 were being left undone until the first error!
3908 (command_loop): Rename do_nothing cleanup to command_loop_marker
3909 so we can see it easily when examining the cleanup chain.
3910 (init_signals): Add another do_nothing for signal handling.
3911 (quit_command): Only try to kill target if it has execution.
3912 Problems in the target stack got us into a state where
3913 inferior_pid was nonzero but none of the targets had execution.
3914 In this state you couldn't exit gdb.
3916 * dbxread.c: Two changes from Peter Schauer.
3917 (echo_command): Fflush output after an echo command.
3918 (show_history): Pass all args to cmd_show_list.
3920 * utils.c (init_malloc): Call mtrace to turn on tracing
3921 if the environment variable MALLOC_TRACE is set to a file name.
3922 * mtrace.c: Add source file which provides a log of every malloc,
3923 free, and realloc to a trace file.
3924 * mtrace.awk: Add source file which analyzes the trace file.
3925 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
3926 (VERSION): Roll to 3.94.3.
3928 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
3929 (check_duplicates): Don't bother with watchpoints.
3930 (set_raw_breakpoint): Comment about danger of this routine.
3931 (watch_command): Parse and eval all args before calling
3934 * solib.c (find_solib): Avoid error in referencing memory to
3935 see if any more shared libraries have been added. This is
3936 particularly useful if the target has terminated. Bug reported
3939 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
3940 in bringing up 3.94.2 on the Sun-3.
3942 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
3943 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
3944 expression (in scope) before reenabling watchpoint.
3945 * signame.c (init_sigs): Add missing declaration of i, fix
3946 sys_siglist declaration.
3947 * source.c (list_command): Fixed range computation to use
3949 * stack.c (backtrace_command): Do not allow command if target has
3950 no stack, print informative error message.
3951 * target.c (target_command): Do not write into command line
3952 because this fails if the target command is used in a user defined
3953 command. [This change was enhanced by gnu to support any-
3954 unique-prefix matching on target names.]
3955 * valops.c (value_struct_elt): Avoid infinite loop on an
3956 erroneous attempt to print the member of function (try p main.p).
3958 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
3960 * expread.y (name_no_typename): Avoid reduce/reduce errors
3961 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
3962 Since the GDB parser really doesn't use name_no_typename in a
3963 name-only context, the parser can't tell the diff between
3964 names and numbers here. Avoid allowing a name_no_typename
3965 to be a NAME_OR_*INT to resolve the conflict.
3967 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
3969 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
3971 * valprint.c (val_print_fields): bitfield printing didn't handle
3972 byte order. Indirect through a few more fns to cope.
3974 * values.c (modify_field): also cope with byte order.
3976 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
3978 Cleanup for release 3.94.2:
3980 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
3981 include files. Roll version to 3.94.2.
3983 * coffread.c (init_stringtab): Read length into unsigned char
3984 array before swapping; don't assume 32-bit longs.
3986 * target.c (target_info): Don't bother with get_sym_file, just use
3987 the symfile global variable.
3988 * symtab.h, symfile.c (get_sym_file): Delete it.
3990 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
3991 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
3992 (read_type): Replace one more error() with complain().
3994 * mipsread.c (parse_partial_symbols): Replace printf with complain.
3996 * i960-tdep.c: Fix copyright attribution.
3998 * config.gdb: Quote all backquotes in doublequotes. You can
3999 quote me on that. BSD 4.4 shell found this one.
4001 * infptrace.c (throughout): The third argument to ptrace is an
4004 * infrun.c (wait_for_inferior): When program has terminated, we
4005 have to call target_terminal_ours before we pop that target off
4006 the stack (e.g. before a call to target_kill or
4007 target_mourn_inferior). This fixes problem where a program
4008 terminates, then GDB stops for (tty output) and you have to type
4009 "fg" to the shell to resume it. FIXME: This code for what to
4010 do after termination really should be in normal_stop instead.
4012 * gdbcore.h (read_memory_check): Change declaration; it changed
4015 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
4016 4.4 prereleases, this avoids a bug in their sgtty compatability
4018 * remote.c: Use terminal.h rather than hand-rolling the same.
4020 * signame.c, signame.h (psignal): Arg is unsigned, not int.
4021 * utils.c (strsave, strstr): Fix arg types.
4022 * valprint.c (val_print): lint
4024 MIPS symbol table support from Per Bothner:
4026 * symfile.c (symtab_fns): Remove initializer table that needs to
4027 be hacked for each new symbol file format supported.
4028 (add_symtab_fns): New function, chains symbol table
4029 handlers into the global list.
4030 (symfile_init): Search this list.
4031 * symfile.h: Add next pointer, declare add_symtab_fns.
4032 * coffread.c (_initialize_coffread): Call add_symtab_fns.
4033 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
4035 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
4036 symbol *). Thus, we no longer need the hack to trash
4037 pst->filename. Good, since that hack confused code in symfile.c!
4039 (reorder_symtabs, destroy_all_symtabs): Removed static
4040 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
4041 Instead, the latter now uses a temporary array (stack-allocated
4042 from an obstack, and then freed).
4044 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
4045 haven't been set in the outermost stBlock of a procedure. This was
4046 a problem with f77 binaries on Ultrix 4.?.
4048 (new_symtab, new_symbol, new_type): Continue changing code to use
4049 obstacks more and otherwise conform to dbxread internal style.
4050 Made the free_code of symtabs be free_linetable (as in dbxread)
4051 instead of free_contents. This implies memory leaks when reading
4052 a new symbol table, until the conversion is finished. Did change
4053 (struct symbol) and (struct type) to be allocated on the
4054 symbol_obstack. Blocks and blockvectors are among the things
4057 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
4058 tested much, but it solved one problem (reported by Meissner), and
4059 cleans up some other things. The problem happened when an
4060 included file contains actual code (functions) and not just
4061 definitions. The mips coff is a little inconvenient there, since
4062 it may cause a procedure to be mapped to the wrong psymtab.
4064 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
4065 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
4066 this will need work for the new core paradigm.
4068 Opcode patches from the net:
4070 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
4071 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
4072 missing altogether - they are added here. From Bruce Bauman.
4073 * mips-opcode.h: The low mask for C0 instructions was too small.
4074 From Garrett Lau. I modified the fix to check the entire 32-bit
4077 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
4080 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4082 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
4084 * dbxread.c (read_type): Pointer subtraction (value_sub in
4085 valarith.c) sometimes failed because the types of the
4086 pointers being subtracted were not identical.
4087 These differed because dbxread.c was allocating pointer types
4088 using dbx_alloc_type+smash_to_pointer_type instead of
4089 lookup_pointer_type. I failed to find a justification for the
4090 former, so I changed it to use the latter. Similarly, I
4091 replaced smash_to_function_type by lookup_function_type,
4092 and smash_to_reference_type by lookup_reference_type.
4094 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
4095 _initialize_mipsread): corresponding changes.
4097 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
4099 * source.c (mod_path): Do tilde_expand on each component of the path,
4100 rather than on the (list of) paths as a whole.
4101 (print_source_lines): Set first_line_listed in addition to
4102 current_source_symtab and current_source_line. If the source was
4103 not findable, after a "dir" command to fix the problem,
4104 a "list" would get the wrong lines.
4106 While I was there... (gnu):
4108 * dbxread.c (read_type): Change error to complaint.
4110 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
4112 First attempt at detailed understanding of symbol table memory alloc.
4114 * dbxread.c (dbx_symfile_read): Free our string table if we
4115 aren't the mainline. Free the "info" struct since we're done with
4117 (init_psymbol_list): Free any previously allocated psymbol lists.
4118 (): FIXME: Should realloc-down the psymbol lists when done reading
4119 the main symbol file?
4121 * symmisc.c (free_symtab): Free fullname field too.
4123 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
4124 (REGISTER_ADDR): Make result type unsigned int.
4126 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
4127 define REGEX must also define REGEX1 (its dependency).
4129 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
4131 * tconfig/i960: No longer works, points you at vxworks960 or
4134 * xgdb.c, XGDB-README: Remove file. Users can get the much
4136 * Makefile.dist: Remove all trace of xgdb.
4138 * breakpoint.c (breakpoint_1): Pass demangle arg to
4139 print_address_symbolic.
4140 (clear_breakpoints): Remove unused function.
4141 (breakpoint_re_set_one): Guts of breakpoint_re_set.
4142 (breakpoint_re_set): Use catch_errors to do them all anyway.
4144 * gdb-int.texinfo (Host versus Target): Add section on what is
4145 a "host" feature versus what is a "target" feature.
4147 * infcmd.c (path_command, path_info): Handle the PATH variable
4148 (object search path) as conveniently as the source search path.
4149 * environ.c (set_in_environ): Set some vars in GDB's environment,
4150 in addition to the child's. PATH, G960BASE, G960BIN for starters.
4151 * source.c (mod_path): New function, from guts of
4152 directory_command, modifies a path. Used by path_command.
4153 (directory_command): Call it.
4154 * defs.h (strsave): Declare.
4156 * utils.c (sevenbit_strings): Add new printing option.
4157 (printchar): Use it.
4158 (strsave): Provide this handy helper routine.
4159 (set_width_command): Rename set_screen_width_command.
4160 (_initialize_utils): "set screen-width" => "set width";
4161 "set screen-height" => "set height"; add sevenbit-strings.
4163 * infcmd.c (do_registers_info): Print floating point registers
4164 in raw hex as well as float format, regardless of whether it is
4165 a "virtual" convertible register.
4166 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
4167 regs as a double, just in case it's being used that way.
4168 * values.c (unpack_long): Comment on array/function coercion.
4169 (unpack_double): Argument is in target byte order now. For
4170 integer arguments, just call unpack_long and float the result.
4171 * m68k-tdep.c: include defs.h for "const" handling.
4172 * remote-nindy.c: Use ieee-float stuff.
4173 (nindy_fetch_registers): Unpack double regs to host double, then
4175 (nindy_store_registers): Pack extendeds to host double, flip
4176 around by misusing unpack_double, send as target double.
4178 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
4179 zero, as when stopped at the first instruction of a process.
4181 * blockframe.c: Fix filename in comment (param.h => tm.h).
4182 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
4183 * tm-68k.h: Fix typos.
4185 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
4187 Changes from a bringup on the DEC Vax under Ultrix 4.0.
4189 * coredep.c (fetch_core_registers): Pass end-address of register
4190 section to register_addr as expected. Don't call supply_register
4191 if we'd just pass it garbage.
4193 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
4195 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
4197 * target.c (push_target, target_info): Cast enums to int for < or
4200 * stack.c (print_frame_info): Identify source file & line
4201 even if we can't print it.
4203 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
4205 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
4207 Clean up IEEE floating point support.
4209 * ieee-float.h: New file.
4210 * ieee-float.c: Write real routines to convert between host
4211 doubles and various target IEEE extendeds.
4212 * m68k-xdep.c: Eliminate assembler code for extended floats.
4213 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
4214 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
4215 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
4216 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
4217 double_to_ieee_extended.
4218 * i960-tdep.c: Define ext_format_i960.
4219 * m68k-tdep.c: Define ext_format_68881.
4220 * sparc-tdep.c: Define ext_format_sparc, though unused.
4221 * Makefile.dist (HFILES): Add ieee-float.h.
4222 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
4225 Obsolete the "coffstrip" program in favor of using BFD's strip.
4227 * nindy-share/coffstrip.c: Remove file.
4228 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
4229 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
4230 * tconfig/nindy960: Remove reference to coffstrip.o.
4232 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
4234 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
4236 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
4237 * dbxread.c: Remove static symfile_bfd.
4238 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
4240 * inftarg.c (child_detach): Pop the child_ops vector if the
4241 detach is successful.
4242 * remote-nindy.c (nindy_create_inferior): Don't push a new
4243 nindy_ops since nindy uses the same one for execution and memory
4245 * core.c (core_ops): Use child_attach and child_create_inferior
4246 rather than default attach and create_inferior functions.
4248 Handle floating point registers in core files.
4250 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
4251 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
4252 This version untested since BFD doesn't yet support sun3 core
4254 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
4255 conventions. Fix comments and style. This version has not
4256 been compiled yet, since we have no HP inhouse.
4257 * core.c (get_core_registers): Look for two sections, ".reg"
4258 and ".reg2", and pass both to fetch_core_registers sequentially.
4260 Revise directory path yet again.
4262 * source.c (forget_cached_source_info): Not static any more.
4263 (init_source_path): New default source path is "$cdir:$cwd".
4264 (dir_command): Handle variable arguments ($cdir, $cwd).
4265 (source_info): Print "Compilation directory" rather than
4266 "Originally compiled in" to remind people of $cdir.
4267 (openp): If the path contains $cwd, use current directory.
4268 (open_source_file): If compilation directory is known, replace
4269 first $cdir in path with the compilation directory.
4270 (print_source_lines): Even if we can't print the lines, set the
4271 current symtab and line for future commands like "info source" or
4272 "breakpoint". Also, error message now contains the file name,
4273 line number, and file access error message.
4274 (_initialize_source): Fix help text to describe changes.
4275 * main.c (cd_command): Forget cached source info when we chdir.
4276 * utils.c (strstr): Add simple implementation.
4278 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
4280 * coffread.c (read_one_sym, init_linetable, init_stringtab):
4281 Byte-swap COFF symbol tables if necessary when reading them in.
4282 Use complain() to replace error message in one spot. Needs
4283 corresponding change in bfd/coff-code.h to make some symbol
4284 swapping routines non-static.
4286 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4288 Merge changes from Eirik Fuller, for UTek.
4290 * defs.h (errno): Add declaration.
4291 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
4292 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
4293 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
4294 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
4295 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
4296 declarations of errno.
4298 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
4300 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
4301 <rpc/rpc.h> and <rpc/types.h>.
4303 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
4305 * i960-tdep.c (examine_prologue): Add new argument limit,
4306 which stops the scan at the end of the prologue, or at the PC.
4307 This fixes a problem where it walks down into the code for the
4308 user's statements if that code looks like function prologues.
4309 Mark Fox and I have been bouncing this code back and forth, making
4310 small changes to it. Callers changed to match.
4312 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
4314 Cleanup for gdb-3.94 release final:
4316 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
4317 the .c files from vx-share and nindy-share, from the various
4318 macros, since they are not found via ALLDEPFILES.
4319 (SFILES): Add tm-i960.h.
4320 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
4321 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
4323 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
4324 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
4326 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
4328 * am29k-tdep.c: Add contribution line.
4329 (examine_prologue): Cache information about function prologues in
4330 the misc-function-vector to avoid lots of references over the
4331 serial line while examining instructions.
4333 * core.c (core_close): New function made from cleanup_core.
4335 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
4336 remote-vx.c, remote.c, target.c, target.h,
4337 Update target_ops vector to add attach, close, and load entries.
4338 Use add_syms_addr_command, not add_file_addr_command, for
4339 add_file. Break out close routine from existing code.
4341 * dbxread.c (really_free_pendings): Don't free pending_blocks;
4342 they are in an obstack.
4343 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
4345 (define_symbol): Add symbol type parameter; change callers;
4346 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
4347 it to influence the symbol class on the i960.
4348 (define_symbol): Swap LOC_CONST's into target byte order.
4350 * exec.c (exec_close): New function.
4351 (exec_file_command): Call it.
4353 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
4354 Fix byte order of frame pointer.
4355 (read_var_value): Result of 0 if var's value can't be found,
4356 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
4357 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
4358 (locate_var_value): Use read_var_value and use its lazy address
4359 as the location of the var's value. Lint.
4361 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
4364 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
4365 obsolete Intel versions in favor of vxgdb versions.
4366 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
4367 code dealing with byte order of values, which Intel did in host byte
4368 order rather than gdb-4's target byte order.
4369 (i960_frame_chain_valid): Move to nindy-tdep.c.
4370 (examine_prologue, skip_prologue, frame_find_saved_regs,
4371 frame_args_address, leafproc_return, saved_pc_after_call,
4372 pop_frame): Add vxgdb versions from Mark Fox.
4373 (examine_prologue, frame_struct_result_address): Add code
4374 to deal with the saved value of G13 (struct return address
4376 (frame_args_address): Modify Mark's version to prefer the
4377 saved value over the current value in the topmost frame.
4378 Cache result in the frame info to avoid performance hair in
4380 (print_fault): Add gdb960 code for printing faults.
4381 (_initialize_i960): Actually call check_host.
4383 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
4384 add stub routines. FIXME, these currently just return zero!
4386 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
4387 (attach_command): Call target_attach, not target_open, now.
4389 * infrun.c (normal_stop): Make global, not static, for vx_attach.
4390 (child_attach): Rename from child_open.
4391 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
4392 don't confuse it with a zero step_resume_break_address.
4394 * inftarg.c (child_detach): Eliminate inferior_pid test.
4395 (child_files_info): Clean up message a bit.
4396 (child_ops): Use child_attach, not child_open, to attach.
4398 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
4399 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
4400 findvar.c to here, since it depends on the contents of the
4401 shadow_contents of breakpoints, but keep if #if 0 since it is
4404 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
4407 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
4408 (ptype_command, display_command): Eliminate have_inferior_p and
4409 have_core_file_p in favor of target_has_stack or
4410 target_has_execution.
4411 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
4412 code for actually finding the values of arguments, though we still
4413 keep track of the maximum stack offset for use in printing unnamed
4414 arguments. Handle missing FRAME_ARGS_ADDRESS.
4416 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
4417 (struct nindy_regs): Define registers passed to/from nindy.
4418 (nindy_fetch_registers, nindy_store-registers): Translate between
4419 nindy and GDB formats for the registers.
4420 (dcache_init): Statically allocate the cache, since it was being
4421 allocated by a malloc that was never freed anyway.
4422 (nindy_create_inferior): Error, not core dump, if no exec file.
4423 (nindy_before_main_loop): Use target_load, not target_add_file.
4425 * remote-vx.c (net_load): Specify large timeout for load
4426 requests. Allow user to break out with INTERRUPT.
4427 (net_break): Remove useless code, clean up. Change callers.
4428 (parse-args, skip_white_space, find_white_space): Clean up arg
4429 parsing to cope with quoted strings.
4430 (net_wait, net_quit): Never call error, just return status.
4431 (vx_read_register, vx_write_register): Cleanup status checking.
4432 #ifdef the code based on which CPU we are using (960 or 68k),
4433 FIXME, this should be completely general but it isn't yet.
4434 (vx_xfer_memory, vx_resume): Cleanup status checking.
4435 (vx_run_files_info): Improve message.
4436 (vx_load_command): Renamed from vx_add_file_command. Allow load
4438 (net_ptrace): Remove unused routine.
4439 (vx_wait): Adopt code from vxgdb960 to cope with broken
4440 connections to target machine and prompt to disconnect. Remove
4441 debug printouts. Map some EVENT_'s to SIGnals.
4442 (add_symbol_stub, vx_open): Print names of object files we found,
4443 and "ok" if we read their symbols OK. Clarify output in general.
4444 (vx_attach, vx_detach, vx_kill): Add these commands.
4445 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
4446 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
4447 "info files" output, and create_inferior, since we already have
4450 * stack.c (frame_info): Replace Frame_unknown with 0.
4451 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
4452 (return_command): Pop until the PC matches as well as the FP,
4453 so it works even if the FP is shared with another function,
4454 as in "frameless" or "leaf" procedures.
4456 * symfile.c (load_command): renamed from add_file_target_command.
4457 (add_syms_addr_command): renamed from add_file_addr_command.
4458 (add_syms_command): Stub to call target_add_syms.
4459 (_initialize_symfile): Change command names and descriptions,
4460 add-file => add-syms, and load from alias to its own command.
4462 * target.c (kill_or_be_killed, maybe_kill_then_attach,
4463 maybe_kill_then_create_inferior): Default for attempts to start
4464 a process, if one is already running, is to ask about killing
4465 it and retry if yes.
4466 (upstack_create_inferior): #if-0 it, strata obsolete it.
4467 (push_target, unpush_target, pop_target): to_close() a target
4468 before unstacking it.
4469 (target_info): Renamed from target_files_info.
4470 (_initialize_targets): Rename "i files" as "i target", accessible
4473 * target.h: Improve comments about the target_ vectored routines.
4475 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
4476 Convert commenting style to standard GNU style.
4477 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
4478 (SKIP_PROLOGUE): No longer a no-op.
4479 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
4480 (*_REGNUM): Sort register numbers.
4481 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
4482 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
4483 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
4484 are now 10 byte extendeds, not 8 byte doubles.
4485 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
4486 for nindy versus vxworks targets. FIXME, this should possibly go
4487 in the target vector.
4488 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
4489 frame_saved_regs and arg pointer with each frame.
4490 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
4491 (FRAME_ARGS_ADDRESS): Use cached result.
4492 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
4493 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
4494 (PRINT_RAMDON_SIGNAL): Call print_fault.
4495 (POP_FRAME): Now works.
4497 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
4498 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
4499 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
4500 (ADDITIONAL_OPTION_HANDLER): use target_load, not
4503 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
4504 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
4506 * valarith.c (value_subscripted_rvalue): Avoid handling
4507 floats and doubles specially; it gave alignment errors. Lint.
4509 * valops.c (value_of_variable, value_of_this): Error if unknown
4512 * valprint.c (print_floating): Bcopy rather than pointer-deref,
4513 to avoid alignment problems.
4514 (value_print): Handle unknown value address.
4515 (cplus_val_print): Two args are ignored; remove them. Change caller.
4516 (val_print): Use unpack_long rather than pointer-deref.
4519 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
4520 to avoid alignment problems.
4521 (value_being_returned): Error if return value unknown.
4522 (set_return_value): Add bogosity warning, FIXME. *
4524 * TODO: A woman's work is never done.
4526 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
4527 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
4528 Add ieee-float.o to OBS.
4529 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
4530 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
4531 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
4533 Changes to generalize the VxWorks RPC protocol slightly, to handle
4534 i960 as well as 68000.
4536 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
4537 * vx-share/reg.h: Produce i960 regs #ifdef I80960
4538 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
4539 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
4540 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
4541 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
4542 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
4543 so they will move in target byte order rather than network
4544 byte order (happens to be the same).
4546 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
4548 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
4550 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
4553 Add contribution lines to various files, showing where they
4556 * breakpoint.c (break_insn, check_break_insn_size,
4557 read_memory_nobpt): Remove to mem-break.c.
4559 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
4562 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
4563 entry has bad register number. This change is not
4564 tested in this release, FIXME.
4566 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
4569 * value.h: Force value's contents field to be aligned to hold
4570 at least a double or a long long (if supported). This avoids
4571 doing bcopy's in and out of the contents field.
4573 (step_1): Avoid coredump under obscure circumstances when we
4576 * symtab.h (misc_info): Add field to misc function vector for
4577 any kind of cached information the target code desires. AMD
4578 29000 uses this to avoid repeating examine_function_prologue's.
4580 * coffread.c: Lint. Remove static symfile, read_section_header.
4581 core.c (have_core_file_p): Lint: remove.
4582 expprint.c (print_subexp): Lint.
4583 infptrace.c, valops.c, valprint.c: lint.
4585 Roll in changes from vxgdb-5.0.1:
4587 * symtab.h: Comment byte order of each address class. Add
4588 LOC_LOCAL_ARG for frame-relative args (960).
4589 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
4590 symtab.c, symmisc.c: ditto.
4592 * infrun.c (init_wait_for_inferior): Clear stop_signal.
4594 * remote.c (remote_resume): Error if resume with a signal.
4596 * symfile.c (prim_record_misc_function): Clear misc_info.
4597 (fill_in_vptr_fieldno): Check stub type of arg.
4599 * valops.c (value_cast): Avoid looking up names of types whose
4600 name we don't know, to prevent coredump. Sun CC produces typedef
4601 rtx and the name of *rtx is zero...
4603 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4605 Roll in changes from final AMD 29000 port (Tiemann).
4607 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
4608 for ../include/a.out.encap.h. This might not work now that BFD
4609 is separately compiled. Instead, BFD support for encap will have
4610 to translate machine type 29k into the right COFF_MAGIC.
4612 * infcmd.c: Remove references to inferior_pid that aren't used
4613 in actual ptrace calls; use target_has_execution, etc.
4614 (have_inferior_p): Remove function.
4615 (program_info): Print target info rather than "process number";
4616 avoid gratuitous messages unless from_tty.
4617 (run_stack_dummy, finish_command): Set proceed_to_finish.
4618 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
4619 main.c: Lint. Lose have_inferior_p().
4620 inferior.h (have_inferior_p): Remove, lint.
4621 (proceed_to_finish): Add flag to ask that all regs be saved
4622 by normal_stop, for the few commands that need it, speeding up
4623 serial I/O. Add comments to stop_registers.
4625 * remote-eb.c: Remove newline from breakpoint message we grep
4626 for. Never time out when running the user program.
4630 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
4632 Roll in changes from vxgdb-5.0.1:
4634 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
4635 symbol in its raw form, we are processing an unlinked ".o" file.
4636 See if the target environment has assigned it an address, using
4637 target_lookup_symbol (VxWorks does), and enter it into the symtab
4640 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
4641 68k versions for a simpler version that assumes zero FP at bottom.
4642 Fixes bug of truncated stack reports.
4644 * target.h (target_lookup_symbol): Define this routine's args
4645 and result, finally.
4647 * target.c (nosymbol): Default routine for target_lookup_symbol.
4648 (target_default): Default lookup_symbol and call_function too.
4649 (files_info): Only print has_all_memory warning if a non-dummy
4652 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
4653 vx_convert_from_virtual): If target does not have floating point,
4654 zero register "values", and avoid doing cross-net conversions.
4655 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
4656 (vx_open): Rearrange code that attaches to target and reads
4657 symbols for all loaded modules, to work if some of the modules
4658 are not accessible. Add symbol_stub() and add_symbol_stub()
4659 as callbacks from catch_errors(). Allow connect attempt to be
4660 interrupted painlessly with ^C (FIXME, there are still some bugs
4661 if the interrupt happens during symbol reading.). Print
4662 final message with puts_filtered, since symbol messages are
4667 * main.c (catch_errors): Only print errstring if non-null.
4668 (command_loop): Avoid an ioctl per command to test ISATTY.
4670 * remote-vx.c (net_load): make static; avoid sophomoric msg.
4671 (vx_xfer_memory): Return correct result!
4672 (vx_files_info): Indicate whether target has float or not.
4673 (vx_lookup_symbol): Complain, not error, if target gone.
4674 (vx_open): Print "Connected" msg before disabling immediate-quit.
4675 [FIXME: lookup_symbol and vx_open changes need testing.]
4677 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
4678 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
4679 contributor lines and update copyrights to 1991.
4681 Changes from an attempted H-PUX host port:
4683 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
4684 defines PT_ATTACH and PT_DETACH but not PT_KILL.
4685 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
4686 * remote-vx.c: include <sys/time.h> for HPUX.
4687 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
4688 "core_file_command" routine to BFD regime. May not work yet.
4690 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
4692 * xgdb.c: Replace X10 version with some VJ version.
4693 (FIXME: Its copyright assignment is not on record.)
4694 * xgdb.c: Update include files to X11R4 (Xaw crud).
4695 (xgdb_display_source, create_text_widget): fix call to
4696 get_filename_and_charpos. Rewack source window stuff for X11R4
4697 (gleaned from include files, and "nm's" of binary libraries, since
4698 I had no doc available).
4699 (append_selection, append_selection_word): Disable with FIXME
4700 since R4 changed interface here.
4701 (create_buttons): Add back the old set of buttons.
4702 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
4704 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
4705 Roll VERSION to 3.94 (not yet final though).
4707 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
4709 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
4710 obstack_int_grow, obstack_int_grow_fast): Eliminate
4711 cast on left of assignment, which gives MIPS cc fits and is
4714 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
4715 F_ALIAS. Use printf, not fprintf, when not passing a file
4717 (compare_opcodes): Check that identical instructions have
4718 identical opcodes, complain otherwise.
4720 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
4721 was reported by Roland McGrath.
4722 (unimp): Only match if exactly zero instruction. (Roland)
4723 (branches and traps): Generate all variations of these
4724 instructions with macros, based on a single call that defines
4725 each condition name and its binary representation.
4726 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
4728 * valprint.c (val_print_fields): Take, and use, format parameter.
4729 This means that "p/x struct" again prints the elements in the
4730 desired format. Changed callers.
4732 * stack.c (frame_info): Use filtered output, and indicate wrap
4733 points. Remove kludgy formatting designed to avoid line wrap.
4735 * utils.c (wrap_here): If the line is already full (because
4736 we had printed a long indent or long wrapped string), do an
4737 immediate newline-and-indent.
4739 * m68k-pinsn.c (print_insn_arg): Bugfix from
4740 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
4741 instruction is incorrectly disassembled as bkpt #8.
4743 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
4744 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
4745 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
4746 and then will dump core (sometimes). I traced it back to an
4747 uninitialized symfile_name in psymtab_to_symtab.
4748 (const_vol_complaint): Add quotes to message.
4749 (define_symbol): Only believe line number if gcc_compiled.
4750 Avoid allocating symbol if we will not return it.
4752 Add target strata support so that newly established targets go
4753 into their right place in the target stack (e.g. a new exec file
4754 doesn't wipe out the ability to access the running process).
4756 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
4757 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
4758 and initialize it properly in all the targets.
4760 * target.h: Document strata. Change return type of push_target.
4762 * target.c (nomemory): new function for dummy memory access.
4763 (tcomplain): Rename complain, now also used in symfile.c.
4764 (push_target): Push targets within strata. New return value shows
4765 whether new target is on top of stack or not. Always keep dummy
4767 (target_files_info): Ignore dummy target.
4769 * core.c (core_open): Warn user, and skip accessing file, if the
4770 core target is not the topmost target in the stack.
4771 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
4774 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
4775 target_ops, it doesn't belong there since we have no regs there.
4776 Change name of target from machine => memory to clarify.
4778 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
4780 * Freeze version 3.93 for release.
4782 * Makefile.dist: Handle vx-share and nindy-share subdirs
4783 properly when building gdb.tar.Z.
4785 * symtab.c: lint; add no_symtab_msg to consolidate the messages
4786 printed in various places, so I could change just one copy.
4788 * dbxread.c, coffread.c: Change references to bfd->iostream
4789 to cast to FILE *, now that BFD avoids needing types defined
4790 in other header files.
4792 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
4794 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
4795 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
4796 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
4797 (actually gcc -Wall).
4799 * dbxread.c: Remove first_global_sym, last_global_sym, since
4800 they are never referenced.
4802 * defs.h (baud_rate): Declare.
4803 main.c: Define it, and add the -b option to set it.
4805 * gdb-int.texinfo: Add text on how to define a new host or target
4806 architecture, prompted by Per Bothner's questions about MIPS
4809 * gdb.texinfo: Document "complaints". Change doc of -q since
4810 gdb no longer prints the copyright and blurb if you specify a file
4811 name to be debugged (just like Emacs). Add doc for Nindy-specific
4812 command line flags for specifying target serial port and such.
4813 Update copyright to 1991.
4815 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
4816 has taken over for us the job of ripping up executable files. The
4817 crud caused Per Bothner's port to not compile.
4819 * infrun.c (normal_stop): Avoid printing "Program exited
4820 normally" if we are in batch mode. This allows a GDB which
4821 executes a program on a target system, to behave like a Unix
4822 command (input from stdin, output to stdout, no extraneous
4825 * main.c (main): Allow additional machine-dependent command line
4826 options to be specified with the ADDITIONAL_OPTIONS,
4827 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
4828 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
4829 processing to occur just before the main loop with
4830 BEFORE_MAIN_LOOP_HOOK.
4831 (main): If a "core file" argument is specified, and it is not a
4832 core file, try it as a process ID to attach.
4833 (symbol_completion_function): Attempt to cope with
4834 "show screen-" TAB, not very successfully. This needs more work,
4836 (batch_file): New function, returns whether we are reading
4837 commands from an interactive tty on stdin, or from somewhere else.
4838 Called by normal_stop since it doesn't get from_tty passed down
4839 to it like many commands do.
4841 * remote-nindy.c: Handle command line options for nindy
4843 (nindy_before_main_loop): Prompt user for tty name if they
4844 don't specify it before getting to the interactive command loop.
4846 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
4847 and -r command line options. Also add hook before main loop
4848 to make it easy to specify a tty.
4850 * TODO: More things to do, one done.
4852 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
4854 * dbxread.c: Make complaint() calls pass pointer, not struct.
4855 Add complaints about badly formatted C++ type information
4856 (const/volatile indicator, and parse errors resulting in
4857 error_type). Fix C++ virtual member fn comment.
4858 (read_struct_type): Avoid bumping pointer if we got a parse
4859 error; this prevents our walking beyond the end of a string.
4860 Terminate loop on null char as well as semicolon.
4861 (process_one_symbol): Fix the LBRAC fix so that it uses the
4862 last previous SLINE, FUN, or SO record's PC address. C++ debug
4863 symbols did not have SLINE records in a useful order compared
4864 to the LBRAC records.
4865 (define_symbol): Handle "catch" records.
4867 * symtab.c (check_stub_type): Added new complain
4868 `stub_noname_complain' and added a consistency check to
4869 keep the debugger from crashing when finishing from an
4870 exception frame. A real fix will be needed later.
4872 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
4874 * infcmd.c (attach_command): Make global.
4876 * Makefile.dist (REMOTE_OBS): Make these compile by default,
4877 but make them easy to comment out. Perhaps later they should
4878 be enabled by what CPU you configure for? FIXME.
4879 (VERSION): Roll to 3.93.
4880 (pinsn.o): Remove rule for obsolete file.
4881 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
4883 Run down a problem that manifested by printing the wrong function
4884 name in stack traces of read_ofile_symtab. Turned out that the
4885 problem was the SunOS 4.1.1 (and previous) C compiler outputs
4886 the LBRAC symbol with an address in the *data* segment, which
4887 blew our binary search through the blocks.
4889 * dbxread.c: Use the complain() facility consistently to bitch
4890 about problems in the symbol file we are reading.
4891 (finish_block): Add code to check the nesting of the blocks;
4892 complain and Procrust them to fit if wrong.
4893 (make_blockvector): Check the order of the blocks, complain
4894 [but don't cope] if wrong.
4895 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
4896 symbols to be sure their PC value is greater than the last SLINE
4897 (line number) symbol we've seen, complaining and adopting the
4898 SLINE PC value if wrong.
4900 * symfile.h (struct complaint, complaint_root, complain,
4901 clear_complaints): Add.
4902 * symfile.c (complain, complaint_root, clear_complaints): Add
4903 facility to deal with non-fatal complaints and to regularize their
4905 (symbol_file_add): Clear complaint counters to allow new complaints.
4906 (initialize_symfile): Add 'set complaints' and 'show complaints'.
4908 * dbxread.c (dbx_symfile_read): Remember the address and size
4909 of the string table for the main symbol file, so we won't read it
4911 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
4912 to avoid reading the string table yet again. Lint.
4913 (throughout): Improve filtered output, including word wrap.
4914 (read_range_type): Improve Bothner's fix to handle other types too.
4916 * utils.c: Improve line wrap implementation. Handle unlimited
4917 width by making chars_per_line unsigned.
4918 (puts_filtered): New, easy, function.
4920 * defs.h (puts_filtered): add.
4922 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
4923 call the identical sort_symtab_syms() in symfile.c instead.
4925 * expread.y: Suggest the `file' command rather than `symbol-file'.
4927 * command.h (enum var_types): Add zinteger for seroable
4929 * command.c (do_setshow_command): Handle var_zinteger. Restructure
4930 nested if's into a switch.
4932 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
4933 we did not stop because of a breakpoint (it must have been for
4934 some other reason, like a "stepi"), so don't print anything.
4936 * symtab.c: Include <sys/types.h> all the time. Now that BFD
4937 doesn't include <sys/types.h>, old SunOS's require it for
4940 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
4942 A test port of gdb-3.92.6 to the Sony NEWS.
4945 Don't normally link in remote- or vx stuff.
4946 Some of it doesn't compile, and it wastes space for 99% of the users.
4947 Remove reference to no-longer-used HAVE_VPRINTF.
4948 Fixed BFD_DEP typo to BFD_DIR.
4950 Fix cast in arg to bfd_h_getlong.
4951 Make char *prefix be const.
4952 Fix how certain range types are mapped into builtin unsigned int types.
4954 Remove 2 #includes. They cause errors (on Sony, at least),
4955 and aren't needed (they wern't in earlier versions).
4957 print_address_symbolic should never demangle labels
4958 (since it prints *assembler-level* labels).
4960 [This was superseded by the change to printcmd below.]
4963 Add some "volatile" return types to avoid warnings.
4964 If MISSING_VPRINTF add vprintf function and not just macro
4965 (since vprintf is used in printcmd.c).
4967 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
4968 (The latter isn't grokked by some PCC-based compilers.)
4970 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
4972 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
4973 * nindy-share/coffstrip.c
4974 Added some forward declarations (otherwise, gcc complains
4975 about implicit extern redefined as static).
4977 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
4979 Changes inspired by Per Bothner:
4980 * printcmd.c (print_address_symbolic): Take additional parameter
4981 specifying whether to demangle.
4982 (print_address): Pass in asm_demangle to control demangling.
4983 (print_address_demangle): New fn, takes explicit arg to control
4985 * utils.c: Add new vars demangle and asm_demangle, and let them
4987 (fputs_demangled): If !demangle, just print the argument.
4988 (fprint_symbol): If !demangle, just print raw symbol.
4989 * valprint.c (val_print): Call print_address_demangle rather than
4990 print_address, to cause demangling to depend on the global
4991 rather than assembler-level demangling setting.
4992 * WHATS.NEW, gdb.texinfo: Document.
4994 * main.c (show_command): Show all settings if no arg.
4995 (initialize_main): Make "info set" the same as naked "show".
4996 * command.c (cmd_show_list): Handle prefix commands in the
4997 list, and print the name of the setting as well as its English
4998 description and value.
5000 Allow gdb functions to specify where a line should wrap if it
5001 exceeds the size of a terminal line. Use it to make the output
5003 * utils.c (set_screen_width_command): New fn, mallocs a buffer
5004 of the right size when screen width changes.
5005 (set_screensize_command, screensize_info): Remove #if 0'd fns.
5006 (wrap_here): New fn, indicates a point in the output where we
5007 should wrap the line rather than just letting it overflow at a
5009 (fputs_filtered): Implement wrapping.
5010 (n_spaces): New fn, returns a pointer to N spaces.
5011 (print_spaces_filtered): Use n_spaces.
5012 * defs.h (n_spaces): Declare.
5013 * stack.c (print_frame_info): Wrap with 4-space indent after
5014 fn name and before filename and line number.
5015 * printcmd.c (print_frame_args): Wrap with 4-space indent
5016 before each argument name is printed.
5017 * valprint.c (value_print): Wrap with no indentation before
5019 (val_print_fields): Wrap with indentation relative to nesting
5020 level before each field name.
5021 (val_print): Wrap with nesting indentation before array elements.
5022 * command.c (do_setshow_command): Avoid extra newlines,
5023 wrap with 4-space indent around values printed, end with period.
5024 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
5026 * breakpoint.c (breakpoint_1): Implement addressprint for
5027 "info breakpoints" display. Change file name and line number
5028 format to " at file:nnn" rather than " (file line nnn)".
5029 * gdb.texinfo: Document.
5032 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
5034 Frozen for gdb-3.92.6 release.
5036 README, WHATS.NEW: Update for 3.92.6 release.
5038 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
5039 coffread.o from configs since it is now built by default.
5040 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
5041 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
5042 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
5043 from configs since it is now built by default.
5045 Makefile.dist: Update for release 3.92.6. Handle files that
5046 have been moved to ../include, ../getopt, or ../bfd. Add
5047 saber.suppress and tests directory. Add config.status to
5048 the release (it will say "none").
5050 coredep.c: Minor formatting fixes.
5052 These changes were made in early December but only checked in now:
5053 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
5054 nindy-share/nindy.c: lint
5055 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
5056 register values coming back from the target; we store values
5057 in target byte order everywhere.
5059 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
5061 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
5063 * valprint.c (cplus_val_print, val_print_fields): New functions,
5064 which print C++ objects. They conspire to avoid printing a
5065 virtual base class more than once, following all the twists and
5066 turns of C++ virtual base rules.
5067 (val_print): Call the above rather than do it by hand.
5069 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
5070 symbol file, not for added files like shared libs. This really
5071 needs to be generalized to a timestamp per file.
5073 * core.c (cleanup_core): Avoid coredump if no core file.
5075 * config.gdb: Accept -host or -target in place of +host or
5078 * coffread.c (find_linenos): Avoid desupported BFD interface
5079 to line numbers. We still read them manually rather than using
5080 BFD's "generic" features.
5082 * gdbrc.tex, threecol.tex: Add GDB reference card and its
5084 Makefile.dist: Add refcard to OTHERS list for creating tar files.
5086 * Makefile.dist: Eliminate use of $< in explicit targets.
5088 * readline/Makefile: Use $< rather than $*.c, which does not
5089 include the VPATH in GNU Make.
5091 * tconfig/i960-bout, tconfig/i960-coff: These are identical
5092 copies of tconfig/i960, added for global configuration
5093 compatability. All i960 versions can read both coff and b.out.
5095 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
5096 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
5099 * TODO: Think of more things to do.
5101 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
5103 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
5104 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
5105 64-bit float conversion.
5107 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
5108 equivalent to sun?os4 so global config works.
5110 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
5112 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
5114 * main.c: Only declare linesize once; declare pagesize not at
5115 all, since it is never used.
5116 (main): Clear newly allocated line before it is used.
5118 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
5120 Further stabilization for the Intel 960.
5122 * Makefile.dist: Parameterize the location of the "include"
5123 and "bfd" directories, as well as "getopt". Add symfile.c.
5124 Link in both dbxread and coffread. Fix up "make depend" to
5125 rewack the locations of include, bfd, and getopt in its output.
5127 * README: Document moving include files, improve some of
5130 * coffread.c: Move common code out to symfile.c. Change
5131 symbol_file_command style interface to use new *_symfile_init
5132 and *_symfile_read interface under BFD. Use BFD internal
5133 info to locate line table, symbols, etc.
5135 * core.c (core_fetch_registers): Rename to get_core_registers
5136 to avoid confusion with fetch_core_registers.
5137 (register_addr): Move to coredep.c, which is already machine
5138 dependent. This leaves core.c pretty clean of dependencies.
5140 * coredep.c (register_addr): Accept this routine from core.c.
5142 * dbxread.c: Move common code (with coffread.c, etc) into new
5143 symfile.c. Each psymtab now contains a pointer to the
5144 format-dependent function that knows how to read it in. Make
5146 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
5147 (process_one_symbol): Add code to complain about a "compiler bug
5148 we muzzle here", if we actually see it.
5150 * eval.c (evaluate_subexp): Insert missing "break" statements
5151 in code that determines whether a variable is an lvalue in
5152 memory, register, or whatever. I detected this via a compiler
5153 bug in which it *almost* mashed out the whole switch statement.
5155 * gdb-int.texinfo: Add minor sections on configuring gdb for
5156 release, and about the README file.
5158 * infcmd.c (registers_info): Fix formatting somewhat. Still
5159 not as pretty as before, but it handles byte swapping.
5161 * remote-nindy.c: If data cache routines are interrupted while
5162 waiting for the remote end, be sure that any uninitialized cache
5163 blocks are on the free list, not on the valid list!
5165 * symfile.h: Flesh out this header file with all the various
5166 routines and variables that have been merged in from dbxread.c
5167 coffread.c, and symtab.c to symfile.c.
5169 * symfile.c: New file, containing code common to dbxread.c,
5170 coffread.c, and some code from symtab.c. All generic code for
5171 reading symbol files should be in here now.
5172 (unrecord_misc_function): Remove unused function.
5174 * symtab.h: Remove file-reading things to symfile.h.
5176 * symtab.c: Remove file-reading things to symfile.c.
5178 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
5179 to decode i960 fault types.
5181 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
5182 target.c: Change type of the "resume" function from int to void,
5183 since its result was never used.
5185 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
5187 * main.c: Replace "stupid" with "caution"; you now "set caution
5190 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
5192 * infcmd.c (do_registers_info): Call val_print to deal with the
5193 byte order of the registers being printed. FIXME, this makes
5194 the formatting of the output uglier.
5196 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
5197 defined, call it for signals the debugger doesn't itself use.
5198 The i960 uses this for more detailed fault information.
5200 * remote.c (remote_open): If arg is null, print help rather than
5203 * sparc-xdep.c (register_valid): Avoid declaring size, since
5204 various modules will think of various sizes depending on the
5205 architecture of their tm-file. FIXME, we need protection against
5206 actually entering one of those modules, which would clobber
5207 storage if not for the target architecture compiled into gdb.
5209 * stack.c (up_command, down_command): Always print the frame
5211 (up_silently_command, down_silently_command): New commands
5214 * i960-pinsn.c (reg), i960-tdep.c: Lint.
5216 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
5217 more parameters than it used to.
5219 * findvar.c (registers): Increase slop to 256 bytes, which should
5220 protect us against even most RISC machines with large register
5222 (locate_var_value): Move declaration inside related ifdef.
5224 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
5225 throughout, to avoid throwing away buffered input from the board.
5226 (nindy_wait): Supply_register takes addr_of_value, not value.
5227 (i960_print_fault): Renamed from i80960_fault.
5228 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
5229 (nindy_store_registers): Avoid regs_changed stuff, just stuff
5231 (nindy_create_inferior): Don't bother to write PC_REGNUM since
5232 we can set the PC in the call to proceed(). Unpush nindy_ops
5233 before pushing it on top, to avoid message to user. Eliminate
5234 commentary from Unix machines that just misleads here.
5235 (reset_command): Fix error message to suggest target command.
5237 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
5239 Release 3.92.5 as frozen.
5241 Stabilize the merged release...with help from lint, Saber C,
5244 Everywhere: Add include files needed to declare return types
5245 of functions called.
5247 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
5249 * breakpoint.h: Add undeclared breakpoint functions, and some
5250 functions for display handling since I couldn't think of a better
5253 * breakpoint.c (insert_breakpoints): Make code for disabling
5254 shared library bkpts more likely to work. It's used when we
5255 rerun a program and stop before the shared library has been
5257 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
5258 cast from pointer, so it squeezes through catch_errors.
5259 (bpstat_stop_status): Fix logic broken some time ago. We now
5260 always create a bpstat if the stop address matches a breakpoint,
5261 even if we don't stop there -- just like the old code used to do
5262 before I got my fingers into it (sigh).
5263 (breakpoint_1): Print "ignore count" after "stop only if"
5264 condition, since that's how it actually works.
5265 (mention): Handle watchpoints as well as breakpoints.
5266 (watch_command): use set_raw_breakpoint and mention to do most
5267 of the work (and initialize all the fields!). Only pass one
5268 arg to parse_c_expression, since that's all it takes.
5270 * command.c (not_just_help_class_command): Rename arg to args
5271 since we ignore "unused argument" warnings on vars named "args".
5272 inflow.c (child_terminal_info): ditto.
5273 infptrace.c (kill_inferior): ditto
5274 main.c (catch_errors, version_info, quit_command, pwd_command,
5275 source_command, dump_me_command, editing_info,
5276 set_history_size_command, set_history, show_history,
5278 stack.c (locals_info): ditto
5279 target.c (target_files_info): ditto
5280 valprint.c (set_input_radix, set_output_radix): ditto
5282 * core.c: Remove old variables for handling core and exec file
5283 sections (data_start, data_end, stack_start, stack_end,
5284 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
5285 text_end, exec_data_start, exec_data_end, text_offset,
5286 exec_data_offset, data_offset, stack_offset). They're
5287 superseded the more general build_section_table and
5289 (get_exec_file): Mention the `file' command.
5290 (read_memory_check): Rename to memory_error, and only call it
5291 in the case of an actual error.
5292 (read_memory, write_memory): call memory_error.
5293 (core_fetch_registers): Register section name is ".reg".
5295 coredep.c: Remove a bunch of crud now that all this file does
5296 is pull the registers out of a core file.
5297 (fetch_core_registers): Rewrite to actually work, I hope.
5299 dbxread.c: Use a.out.gnu.h, not system a.out, now.
5300 Replace index() with strchr(). Remove all the pre-BFD macro
5301 definitions for accessing the symbol file.
5302 (struct dbx_symfile_info): Encapsulate the information that
5303 dbx_symfile_init needs to pass to dbx_symfile_read in this
5306 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
5307 dbx_symfile_discard): Rearrange symbol file reading to divide
5308 the format-specific part from the format-independent part,
5309 leaving the format-independent part such as file name expansion
5310 and opening in symtab.c. This replaces
5311 partial_symbol_file_open and partial_symbol_file_read.
5312 Symbol_file_read, add_file, add_file_target_command,
5313 add_file_addr_command move to symtab.c. Pass an explicit
5314 "mainline" flag for when reading the main symbol table, rather
5315 than relying on the offset address to be zero or nonzero.
5317 (dbx_symfile_read): Don't allow void *'s to be printed as
5319 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
5320 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
5321 macro" debug version really work.
5322 (read_dbx_symtab): Remove unref'd parameter inclink.
5323 Avoid swapping N_SLINE symbols, for speed.
5324 Merge N_TEXT!N_EXT case with the other external symbol
5325 definitions' case. Add comments.
5326 (start_psymtab): Allocate the symfile name in the psymtab on
5327 the psymbol_obstack, rather than using the caller's storage.
5328 (end_psymtab): Only allocate a dependencies list if there are
5330 (psymtab_to_symtab_2): Use BFD when reopening file to read
5331 its symbols for real.
5332 (read_struct_type): Add FIXME comments where it needs work
5334 (read_huge_number): Add FIXME about overflows.
5335 (read_range_type): Add FIXME about comparing a long to 1<<32.
5337 * coffread.c: Minor changes to move things closer to the new
5338 regime with symtab.c and dbxread.c Major work is still needed
5341 * exec.c (exec_file_command): Remove old variables (see core.c
5343 (xfer_memory): If memory transfer is right at the end of a
5344 section, don't lose.
5346 * findvar.c (get_saved_register): If value is in a real
5347 register, LVAL is lval_register, not lval_memory.
5349 frame.h: Declare print_sel_frame and record_selected_frame.
5351 gdb-int.texinfo: New file, for GDB internals documentation.
5352 Very simple, unformatted doc of cleanups is there for now.
5354 gdbcore.h: Remove obsolete variables that described a.out
5355 section addresses and offsets. (See core.c above.)
5356 Declare fetch_core_registers and registers_fetched.
5358 getopt.c: Declare char *alloca(); even on SPARC.
5360 infcmd.c (run_command): Call target_kill rather than
5362 (step_command, next_command, stepi_command, nexti_command):
5363 Declare from_tty parameter even though we don't use it.
5364 (run_stack_dummy): argument BUFFER is a char array, not
5365 a pointer to REGISTER_TYPE.
5366 (finish_command): using_struct_return needed a value *,
5367 not a struct symbol *.
5369 * infptrace.c (child_xfer_memory): To avoid dependency on
5370 where sections are in memory, try PT_WRITE_D and if that fails,
5371 try PT_WRITE_I. Most Unixes don't care which you use.
5373 * infrun.c (step_resume_break_shadow): Change to array to
5374 match other breakpoint shadow storage.
5375 (clear_proceed_status): Pass address of bpstat to
5376 bpstat_clear, not the bpstat itself.
5377 (child_create_inferior): FIXME comment about if the child
5379 (start_inferior): Remove old function.
5380 (child_open): Use target_kill rather than kill_inferior.
5381 (wait_for_inferior): Ditto.
5382 (insert_step_breakpoint, remote_step_breakpoint): Use
5383 new step_resume_break_shadow.
5385 * inftarg.c (child_wait): If all child processes die,
5386 pretend that the one being waited for exited with signal 42.
5388 * main.c (command_line_input): When scanning for comments,
5389 don't coredump on unclosed quotes.
5390 (quit_command): Use target_kill rther than kill_inferior.
5391 (_initialize_main): Rename class_user from "user" to
5394 * printcmd.c (print_command_1): Initialize "fmt" if no format
5395 is specified by the user.
5396 (print_frame_args): Only add to args_printed if we are
5397 actually fetching args from the stack (avoiding undefined
5399 (_initialize_printcmd): Remove bogus \{ from string.
5401 * remote-eb.c (eb_open): Avoid coredump on no argument.
5403 * remote-nindy.c: Bring out of Intel environment into new
5404 target environment. Remove all conditional compilation on
5405 I80960. Massive hacking throughout.
5406 (nindy_xfer_inferior_memory): New routine stolen from
5408 (nindy_create_inferior): New routine pieced together, probably
5409 not quite working yet.
5410 (nindy_ops): New target_ops struct for nindy.
5412 * remote-vx.c: Use write_memory rather than target_write_memory
5413 to get error checking.
5414 (vx_add_file_command, vx_open): Use symbol_file_add rather than
5416 (vx_create_inferior): Use target_terminal_ours...
5418 * signame.c (_initialize_signame): Always initialize, since
5419 we need the table for things other than psignal.
5421 * solib.c (solib_add): Use symbol_file_add, not add_file.
5422 (solib_address): Return boolean result rather than struct
5423 pointer which nobody else knows the type of.
5425 * sparc-tdep.c, valops.c: Use write_memory rather than
5426 target_write_memory, to get error checking.
5428 * stack.c (locals_info, catch_info, args_info,
5429 get_selected_block, frame_command, up_command): Use
5430 target_has_stack, rather than have_inferior_p or
5433 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
5435 * symfile.h: New file, defining the interface between the
5436 generic and object-file-specific symbol reading code.
5438 * symtab.c: Move generic symbol-reading interface to symtab.c,
5439 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
5440 table to map BFD targets to symbol-reading modules in GDB.
5441 Change index to strchr.
5442 (lookup_struct_elt_type): Use error() rather than hand-made
5443 simulations thereof.
5444 (lookup_partial_symbol): Speedup slightly when length == 0.
5445 (symbol_file_add): New function.
5446 (symbol_file_command): Call it.
5447 (symfile_open, symfile_init): New function.
5448 (add_file_target_command, add_file_addr_command): moved from
5451 * target.c (target_command): use target_kill.
5453 * target.h (target_files_info): Don't declare, never called
5456 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
5457 files to determine stack end address.
5459 * valarith.c (value_x_binop, value_x_unop): Change error message
5460 to be more useful. Pass proper argument to value_struct_elt.
5462 * valops.c (value_assign): FIXME comment that long long
5463 bitfields will break here.
5465 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
5466 Update `make saber_gdb' to work better.
5468 * TODO: A woman's work is never done.
5470 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
5471 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
5472 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
5473 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
5474 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
5475 valops.c, valprint.c, exec.c: Lint.
5478 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
5480 Continuing Intel 960 port merge of GDB.
5482 * Makefile.dist: Merge i960 "nindy-share" files. Rename
5483 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
5484 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
5485 Wack over "make depend" so it handles files in subdirectories
5486 vx-share, nindy-share, bfd, and in the current directory.
5488 * blockframe.c (get_prev_frame_info): Remove fatal error
5489 if stack not defined.
5491 * core.c (core_open, core_detach): New functions that handle
5492 the old "core-file" command as "target core" and "detach" instead.
5493 (core_file_command): Call them.
5494 (core_xfer_memory): Use common routine xfer_memory.
5496 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
5497 dbxread now uses bfd for everything but symbol reading itself.
5498 BFD internals are used to drag out the relevant file offsets.
5499 (partial_symbol_file_open): Change args all around for BFD.
5501 * symtab.c: Rename "value" to "val" everywhere, so we can
5503 (symbol_file_command): New command, moved from dbxread.c
5504 and coffread.c. It uses BFD to read the file, then vectors
5505 based on its type, to dbx or coff symbol readers.
5506 * symtab.h: Extern a few vars for symbol_file_command.
5508 * target.h: Breakpoint takes a char * save area, not a char **.
5510 * valprint.c (val_print): When unpacking bitfields, offset
5511 the address in gdb of the value, if it is declared with a shorter
5512 type. Remove the last "runtime kludge test" of host byte order.
5514 * utils.c: Remove old my_bfd_read routine.
5516 * stack.c (frame_info): Use target_has_stack. Print program counter
5517 register's actual name rather than "pc", since it's called the
5518 "ip" (instruction pointer) on the i960 (sigh).
5520 * target.c (target_command): Add command for selecting a target
5521 type and calling its open routine. This is used for initiating
5522 communication with a particular target, in a generic way.
5524 * tm-i960.h: Update for modern gdb. Remove semicolons from
5525 various macros. Handle reading struct return convention, and
5526 error-out attempts to return structs with the "return" command.
5527 Be sure gdb doesn't think we know how to call functions in the
5530 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
5531 to i960_xxx in lower case.
5532 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
5533 not being defined yet.
5535 * remote.c (remote_open): Call start_remote to initialize
5536 wait_for_inferior during open.
5537 (remote_xfer_inferior_memory): Return length written rather
5540 * remote-vx.c (target_command -> vx_open): Use new generic
5542 * remote-eb.c, inftarg.c, exec.c: ditto.
5544 * infrun.c: Fix comments.
5545 (attach_program -> child_open): Use new generic target command.
5546 (wait_for_inferior): Clear saved register values before target_wait,
5547 so target_wait can set some of them if convenient.
5549 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
5550 Return success indicator, not void.
5551 (child_xfer_memory): Avoid fetching initial word if we'll
5552 overwrite it anyway.
5554 * infcmd.c (attach_command): Use new generic target open routine.
5555 (_initialize_infcmd): Update doc on attach and detach commands.
5556 (do_registers_info): Merge in a byte-order problem as a FIXME
5559 * findvar.c (find_saved_register): Avoid problem in current frame.
5560 (read_relative_register): Ditto.
5561 (write_register): Convert byte order on the way out.
5563 * exec.c (file_command): Add.
5564 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
5565 (xfer_memory): Common function between core_xfer_memory and
5567 (exec_xfer_memory): Use it.
5569 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
5571 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
5572 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
5573 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
5575 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
5577 Merge Intel 960 port of gdb, continuing...
5579 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
5580 symbol_file_command): Pass from_tty arg to hush 'em up.
5582 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
5583 Add magic numbers for 960 COFF format.
5585 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
5587 Merge Intel 960 port of gdb, from Intel "1.2" release.
5589 CHANGE_LOG entries from their port, which was based on
5592 Thu Sep 6 11:02:22 PDT 1990
5593 Remove temp file if download is interrupted.
5595 Wed Aug 1 09:08:33 PDT 1990
5596 Now uses binary protocol to talk to NINDY.
5597 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
5598 Times out after 5 seconds when trying to talk to NINDY.
5600 Tue May 29 12:54:49 PDT 1990
5601 Added variable baud rate (-b switch).
5602 Source code reorganization.
5604 Thu Apr 26 11:09:55 PDT 1990
5605 More cleanup of batch mode; specifically, execute "-s", "-e", and
5606 "-se" switches as soon as they are encountered on the invocation line.
5608 Fri Apr 20 13:47:15 PDT 1990
5611 Thu Apr 19 09:54:28 PDT 1990
5612 Add 'reset' command.
5614 Wed Apr 18 09:48:07 PDT 1990
5615 After opening remote tty, wait for 1 second to go by without input
5616 from it before trying to talk to NINDY (fixes problems with the
5617 Heurikon HK80/V960E).
5619 Mon Apr 4 16:33:05 PDT 1990
5620 Some output was not being suppressed in 'batch' mode.
5622 Thu Mar 22 15:31:11 PST 1990
5623 Ask user if old symbol table should be deleted when new file is
5626 Allow user to run a program downloaded before gdb960 was brought up.
5628 Correct "exec-file" help message for i80960 context.
5630 Correct bug in calculating user space address: could occasionally
5631 corrupt user program.
5633 Make sure to zero low-order bits in rip's because of bug in 960CA
5634 A-step part: could cause operation faults when "next"ing across
5637 Correct bug that made it impossible to get source line numbers for
5638 code loaded at addresses higher than 0x7fffffff.
5640 Wed Jan 10 12:43:22 PST 1990
5641 Open remote tty for exclusive use.
5643 Fri Jan 5 12:14:42 PST 1990
5644 Correct disassembly (CA manual was right after all):
5645 opcode for sysctl is 0x659
5647 Mon Oct 23 12:03:04 PDT 1989
5648 Use G960BASE and G960BIN environment variables to find 'sx' utility.
5650 Mon Oct 16 14:15:09 PDT 1989
5651 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
5653 Mon Oct 2 15:56:31 PDT 1989
5655 Added 960CA disassembly support.
5657 To simplify maintenance:
5658 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
5660 - eliminated opcode.h: incorporates tables into i960-pinsn.c
5661 - moved 960-specific routines from i960-pinsn.c to i960-md.c
5662 - made disassembly interface identical to that in gdmp960.
5666 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
5668 * target.h: Allow targets to stack. Add target_has_memory,
5669 _registers, etc. Restructure memory access and "info files"
5670 to walk the target stack.
5671 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
5672 target.c: Change tables to match target.h.
5673 * inflow.c (child_mourn_inferior): pop child_ops.
5674 (generic_mourn_inferior): Use new has_stack flag.

5676 * inftarg.c (child_files_info): New "info files" regime.
5677 * remote-eb.c: New memory regime, new info files.
5678 * remote-vx.c: New memory regime, new info files. Now use
5679 separate targets for VxWorks attachment to machine, and
5680 actually running a process under VxWorks, since one has
5681 stack & execution & regs and the other doesn't.
5682 * remote.c: New memory regime, new info files.
5683 * sparc-xdep.c (fetch_core-registers): New memory regime.
5684 * target.c: New routines and support for stacked targets,
5685 new memory regime, new info files regime.
5688 Generalize section handling for an arbitrary number of sections,
5689 including use of the new BFD (binary file) library.
5690 * gdbcore.h: Add struct section_table.
5691 * exec.c (build_section_table): Iterate all sections and
5692 record what gdb needs to know about them.
5693 (exec_command): Use it.

5699 * dbxread.c: Quick changes to make it compile with new BFD.
5700 * utils.c (error): Avoid using bfd_error in generic routines.
5702 * core.c (core_fetch_registers): Get from the ".regs" section of
5704 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
5706 * inferior.h (attach_flag): Export.
5707 * infcmd.c (run_command): use new target_create_inferior.
5708 * infrun.c (child_create_inferior): Don't return result.
5709 * Makefile.dist (VERSION): 3.91.4.
5711 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
5713 * breakpoint.c (bpstat_num): Handle breakpoints which have
5714 since been deleted, such as temporary breakpoints.
5715 infcmd.c (program_info): ditto.
5717 * core.c (core_file_command): Display the frame where the core
5722 * remote-vx.c (target_command): Merge in target command from
5723 targ-vx.c. A few other cleanups.
5725 * TODO, Projects: Lots more stuff to do...
5727 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
5729 Massive changes to wall off the remote-debugging interface
5730 behind a function vector. The port to handle VxWorks targets
5731 is also part of this.
5733 All files: Replace references to renamed functions,
5734 remove references to remote_debugging, remove references to
5735 have_include_file, have_core_file in favor of target_has_stack,
5736 target_has_memory, etc.
5738 * Modularize the breakpoint interface.
5739 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
5740 a breakpoint instruction.
5741 breakpoint.c: struct breakpoint's shadow_contents now sized as
5743 (insert_breakpoints): Vector to target to install breakpoints.
5744 (remove_breakpoints): Vector to target here too.
5745 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
5746 sparc-tdep.c (single_step): Use new breakpoint interface for
5747 the single-step breakpoints.
5748 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
5749 New file, contains routines to insert and remove breakpoints by
5750 reading out the old contents and later replacing them. This is
5751 how ptrace breakpoints work, and many remote systems as well.
5753 * tm-vxworks68.h: New config file, overrides a few things for
5754 Wind River's preferences.
5756 * target.h: New file, for transfer vector used to talk to the
5757 inferior (child, attached, core, exec, remote, etc). All accesses
5758 to the thing being debugged should come through these vectors.
5759 target.c: New file, routines to handle transfer vector.
5760 (various files): Add transfer vectors XXX_ops for the various
5761 targets and pseudo-targets (core files, etc) we support.
5763 * breakpoint.c (bpstat_stop_status): Further explorations of
5764 watchpoints and why things don't work all the time.
5765 (bpstat_alloc): New fn to allocate a bpstat and chain it.
5767 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
5768 the local gdbinit if it doesn't already have it.
5770 * core.c (core_ops): add and install.
5771 Allow core debugging without exec file.
5773 * dbxread.c (free_and_init_header_files): Merge two fns.
5774 (end_symtab): Free named symbol table when a new version comes in.
5775 (read_dbx_symtab): Relocate all kinds of symbols with base
5776 address. First step toward handling different text, data, bss
5778 (add_file_addr_command): Renamed add_file_command.
5779 (add_file_command): Vector to remote handler.
5780 Add "load" as an alias for "add-file" command.
5782 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
5783 non-returning functions.
5785 * exec.c: Add exec_ops, and push it as a target when an exec
5788 * infcmd.c (run_command): Pass executable file name and arg list
5789 separately when starting an inferior. Permit "run" when no exec
5790 file is specified, for VxWorks.
5791 (detach_command): Move to child_detach in inftarg.c.
5793 * inftarg.c: New file. Unix-child-specific routines, and the
5794 child_ops structure.
5796 * inferior.h (registers): Export "registers" as the way for
5797 target dependent register handlers to find gdb's local copy of
5798 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
5799 since it is now used by places that want wait_for_inferior to
5800 handle the grunge but want to see every trap from the inferior.
5802 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
5803 Eliminate remote_debugging hooks in terminal handling.
5805 * infrun.c: Replace start_inferior with child_create_inferior.
5806 Move all the hair of Unix shells and ptrace idiosyncracies into
5807 child_create_inferior, so remote handlers don't have to deal.
5808 Remove running_in_shell. Rename stop_after_attach to
5809 stop_soon_quietly, and use it in a few other places where we want
5810 to just call wait_for_inferior and get control back on the first
5811 trap. trap_expected now never takes a value > 1.
5812 (init_wait_for_inferior): Initialize static vars when a new
5815 main.c (gdbinit): Add new hook for .gdbinit file name, let
5816 it be overridden by config files as GDBINIT_FILENAME.
5817 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
5818 Both of these are used for VxWorks gdb.
5820 mcheck.c: rename include file "gmalloc.c" to avoid problems
5821 with system include file "malloc.c".
5823 param-no-tm.h: New include file, same as param.h but does not
5824 include the default "tm.h" file. This is used in files where
5825 the target is known, e.g. remote-eb.c or sparc-xdep.c.
5827 param.h: Now just a shell that includes tm.h and param-no-tm.h.
5829 remote-vx.c: New file, VxWorks remote debugging support. Uses
5830 RPC routines that are shared with the target system, in directory
5833 remote.c: Vectorize remote interface.
5835 source.c: Globalize source_path, and make an alias "l" for "list"
5836 since we now have the "load" command.
5838 sparc-xdep.c: Use new param-no-tm.h.
5840 symmisc.c (free_named_symtab): Add new function from Wind River.
5841 However, ifdef it out for now while we think about what it should
5844 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
5846 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
5847 non-Unix-children handle this with their own code in the target
5850 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
5851 source and target lists. Add vx-share to default list of include
5852 directories. Add new files to src and target lists: mem-break,
5853 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
5854 ${srcdir} versions of munch and createtags are used.
5856 * valops.c (find_function_addr): Split out of call_function.
5857 (call_function_by_hand): Rename call_function; this function
5858 calls functions in the target by laboriously patching the target
5859 word-by-word with the right stack, args, regs, etc.
5862 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
5864 Handle AMD 29000 a bit better.
5866 * remote-eb.c (readchar): Mask received char log to make it readable.
5867 (remote_start): Pass arguments down to executing program.
5868 Make startaddr unsigned.
5869 infrun.c (start_inferior): Accept args, pass them to
5871 infcmd.c (run_command): Pass args down to start_inferior.
5873 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
5874 the target object file format.
5875 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
5877 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
5878 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
5880 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
5882 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
5883 * TODO: We did a few things, we have more to do though.

5886 * inflow.c (inferior_died): Clear deferred stores.
5888 * Debug problems with dummy frames and calls to the inferior.
5889 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
5890 * sparc-tdep.c (do_restore_insn): Simplify.
5891 (sparc_frame_find_saved_regs): Simplify and fix what we find.
5892 (sparc_push_dummy_frame): Simplify and fix what we push.
5893 (sparc_pop_frame): Slightly more hair here, deciding whether
5894 we are restoring a saved PC or returning to a return address in %i7.
5895 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
5897 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
5898 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
5899 * obstack.h (chunkfun): ditto.
5900 * defs.h (xmalloc, xrealloc): ditto
5902 * utils.c (quit): Grab the terminal from the child if necessary.
5904 * inflow.c (term_status_command): Rename to term_info, change
5907 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
5908 (is_delayed_branch): Speed up.
5909 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
5910 Still missing some float ops, and needs testing.
5912 * Support for input and output radixes other than base 10
5913 * defs.h (input_radix, output_radix): Declare.
5914 * expread.y (yyparse, parse_number): Handle changes of input
5915 radix, and ambiguous names-or-numbers in radixes >10.
5916 * printcmd.c (print_scalar_formatted): Print formatted hex
5917 numbers in varying column widths.
5918 * valprint.c (val_print): Use output_format to print scalar ints.
5919 (set_input_radix, set_output_radix, set_radix): Create.
5920 (set_output_radix): Set output_format from output_radix.
5921 (_initialize_valprint): add `set radix' but leave the others off.
5923 * main.c (execute_command): Let stupid questions be turned off.
5924 (_initialize_main): Handle "set stupidity", etc.
5926 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
5927 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
5929 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
5931 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
5932 bfd stuff is still screwed up, but with some manual work, it
5935 * breakpoint.c (bpstat_do_actions): Start over if a command
5936 proceeds the inferior, since the inferior will have stopped and
5937 will need to have its new stop-actions taken care of.
5939 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
5940 compiler fits, simplify it.
5942 * gdb.texinfo (directory command): Doc new dir command.
5943 source.c (directory_command): "dir" now puts things on the front
5944 of the path, moves dups up front, and handles multiple names
5945 on the command line, inserting each one in order. It also
5946 blows away cached line and full_filename info.
5948 * stack.c (backtrace_command): Skip "more stack frames follow"
5951 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
5952 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
5953 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
5954 The only odd one was Gould NP1, which had defined vprintf to
5957 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
5958 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
5959 variable, inspect_it.
5960 valprint.c (print_string, val_print): Use the global inspect_it
5961 to indicate whether to print in Epoch style or normal style.
5963 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
5965 * printcmd.c (call_command): add an alias for the "print" command
5966 which runs expressions and doesn't print the result if void.
5967 (print_command_1): implement it.
5969 * command.c: Remove #if 0'd code. Initialize all the fields
5970 in add_cmd (). Rename do_nothing_command to
5971 not_just_help_class_command, and make it externally visible.
5972 command.h: add user_commands to struct.
5973 * main.c (define_command): Don't overload c->function with a char
5974 string as well as a function pointer.
5976 * eval.c (evaluate_subexp): Reinstall tiemann changes to
5977 calling convention of value_struct_elt () that got dropped in
5980 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
5981 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
5983 * tm-sparc.h (POP_FRAME): replace some constants with defines.
5985 * sparc-xdep.c (store_inferior_registers): defer stores to regs
5986 until a good time (e.g. when we are about to run the child),
5987 saving ptrace calls.
5988 * infrun.c (proceed): handle DO_DEFERRED_STORES.
5989 * tm-sparc.h: define DO_DEFERRED_STORES.
5991 * sparc-xdep.c (store_inferior_registers): when storing float
5992 registers, don't store stack regs too. When storing the SP,
5993 however, DO store the stack regs too. This fixes a bug in which
5994 the dummy frame is not recognized when a call_function finishes,
5995 because its frame pointer (in the stack regs) was never
5997 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
5998 even though we don't know how to read them from an inferior.
5999 valops.c (call_function): Comment about storing SP.
6001 * infrun.c (save_inferior_status): Save away the original bpstat
6002 chain so it can be restored later. Install the copied version for
6003 use by whoever saved the status. It will be blow away by
6004 restore_inferior_status, and the original chain restored. This is
6005 important for people who have pointers into the original.
6007 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
6008 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
6009 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
6012 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
6014 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
6015 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
6016 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
6018 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
6020 * Merge Mike Tiemann's multiple inheritance changes from Sun.
6021 Store the baseclasses in a type struct starting from array element
6022 0 rather than from the unusual array element 1.
6024 dbxread.c: the above.
6025 (virtual_context): Add
6026 Read new debug information about which virtual function table
6027 a virtual function is from, and store it in fn_field.fcontext.
6029 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
6030 TYPE_FN_FIELD_STATIC_P.
6032 symtab.c: the above.
6033 valops.c: the above. Handle pointer casts of object *'s.
6034 (search_struct_method): Add.
6035 (value_struct_elt): First arg is now a pointer to a value, and is
6038 valprint.c: the above.
6039 values.c (value_virtual_fn_field): Add type arg. Handle
6040 offsetting to the proper object when calling virtual fns.
6042 (baseclass_addr): Add valuep arg.
6044 * README: Document the current state of BFD config (missing).
6045 * TODO, ChangeLog, Makefile.dist: Roll version.
6046 * WHATS.NEW: Add summary of changes since 3.5.
6048 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
6050 * dbxread.c (read_struct_type): Clear bit vectors whenever
6052 symtab.c (B_CLRALL): define.
6054 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
6055 using == rather than =. Huh... This fixes the dreaded problem
6056 wherein builtin_type_int becomes TYPE_CODE_FLT.
6058 * core.c (info_files): Show the inferior pid.
6060 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
6061 already knows how to look in the source directory.
6063 * Remove psymtab hair from many places. Remove duplicated code
6064 for searching symbol tables. Hide psymtabs from most places.
6065 Make it fast to get from a psymtab to its symtab.
6067 blockframe.c (blockvector_for_pc): Remove psymtab hair.
6068 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6069 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
6070 dbxread.c: export psymtab_to_symtab, make it work if called N times.
6071 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
6072 new symtab completely. New psymtabs get symtab pointer
6073 initialized to zero. Remove MI warning printf.
6074 symtab.h: Comments. Add psymtab to symtab pointer.
6075 (PSYMTAB_TO_SYMTAB): New macro.
6076 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
6077 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
6079 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
6081 (print_frame_info): Avoid special-casing symbols that have not yet
6084 * source.c (open_source_file): Quick path if we have already
6085 located the source file by its full name.
6087 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
6088 find_pc_psymtab. When a name is found in the misc function
6089 vector, search the symbol table for its mangled name, not the
6090 name that the user typed.
6092 * bfd.h: Fix missing comment terminators, make #endifs match.
6094 * valarith.c (value_less): Handle unsigned int comparisons.
6095 Add FIXME about pointer compares, which assume host and target
6096 pointers are the same.
6098 * command.c (do_nothing_command): lint
6099 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
6100 fix comments on debug symbol format for visibility. Actually set
6101 visibility of symbols.
6102 main.c (echo_command): lint; use <readline/history.h>.
6103 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
6104 obstack.h (_obstack_blank): Rearrange pointer math to avoid
6105 pointing past end of allocated memory; saber complains.
6106 obstack.h: Declare the external functions that we use.
6107 valarith.h: use <string.h>
6108 solib.c (solib_add): lint.
6110 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
6112 * main.c (initialize_main): Default info_verbose to off, now that
6113 symbol reading is fast.
6114 (quit_command): Avoid clobbering exec_bfd while quitting.
6116 * Initial BFD (binary file diddling library) merger:
6117 coffread.c: Change AOUTHDR to struct exe_hdr.
6119 core.c: initialize initialized data at compile time.
6120 (core_file_command): Move from coredep.c, convert to bfd.
6121 (xfer_core_file): Convert to bfd.
6122 exec.c (exec_file_command): use bfd routines.
6124 mips-tdep.c: Remove exec_file_command and friends.
6127 * coredep.c: (fetch_core_registers) Convert core_file_command to
6128 fetch_core_registers.
6129 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
6131 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
6132 (my_bfd_read): More bogosity, which I don't think we call.
6133 (program_name): Remove this atrocity asap!
6135 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
6138 values.c: allocate_repeat_value was not clearing the
6139 optimized_out field.
6140 (value_static_field): minor stylistic fix (wrong macro was used).
6141 valops.c (value_struct_elt_for_address): didn't work for C++
6144 * signame.c (_initialize_signame): Initialize signal names once.
6146 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
6147 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
6148 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
6150 * remote-eb.c: Support user-settable baud rates on the serial port.
6152 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
6154 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
6156 * tconfig/sun3os4: Remove warning about native assembler,
6157 since it also occurs in the xconfig file.
6159 * findvar.c (registers): Allocate some slop after `registers'
6160 to prevent stray accesses from trashing the next variable.
6162 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
6163 on the sun-3, by changing the #ifdef from `sun3' (which is not
6164 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
6165 vars, which happened to follow `registers' in the executable.
6167 * readline/history.c (history_search): Heed gcc-2's advice
6168 and parenthesize && inside ||).
6170 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
6171 tm-29k.c: Insert FSF copyright headers.
6173 * remote-eb.c: Better comments.
6175 * Makefile.dist: Update to 3.91.6.
6176 * TODO: note PREPARE_TO_STORE problem.
6178 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
6180 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
6182 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
6184 * infrun.c (wait_for_inferior, at end): Don't set up
6185 prev_* if the inferior no longer exists.
6187 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
6188 CANNOT_EXECUTE_STACK.
6189 valops.c (call_function): Use it.
6191 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
6193 * inferior.h (PC_IN_CALL_DUMMY): New macro.
6194 infrun.c (wait_for_inferior, 2 places): Use it.
6196 * values.c (value_being_returned): Only use
6197 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
6199 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
6200 right thing for remote-eb.c.
6202 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
6203 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
6205 * blockframe.c: Put get_frame_saved_regs inside #if !defined
6206 (FRAME_FIND_SAVED_REGS).
6208 * findvar.c ({fetch,store}_registers): Check for
6209 REMOTE_{FETCH_STORE}_REGISTER macro.
6211 * findvar.c (get_saved_register): Add argument lval and
6212 change meaning of argument addr.
6213 findvar.c: Change calls to get_saved_register to reflect
6214 new calling convention.
6215 valops.c (value_assign): Use get_saved_register instead of
6216 find_saved_register.
6218 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6220 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
6221 an (uninitialized) pointer to one. Use "&" when passing it
6224 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
6226 * coffread.c (getfilename): Use DGUX x_offset and x_name if
6229 * coffread.c (symbol_file_command): Put semicolon after
6231 Put safe_to_init_tdesc_context in #if defined (TDESC).
6232 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
6233 coffread.c: #include <sys/stat.h>.
6234 (read_coff_symtab): Typo: in_source_files -> in_source_file.
6235 Add missing ')' in check for "lc%" and friends. Remove
6237 Declare read_one_sym() at top of file.
6238 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
6239 MC68WRMAGIC can have the same value without causing a duplicate
6242 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
6244 * Allow a Makefile to be built without building the
6245 tm and xm file links that screw up builds in subdirectories.
6246 This is done with `config.gdb none', then you can do things
6247 like `make gdb.tar.Z'.
6248 * tconfig/none: Config file for no target system
6249 * xconfig/none: Config file for no host system
6250 * config.gdb: If no TM or XM files are called out by the
6251 host or target file, don't make links for them.
6253 * cplus-dem.c: Add documentation.
6255 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
6256 simple error, so the user's gdb doesn't crash due to some object
6257 file problem (e.g. somebody is rebuilding the file out from under
6260 * printcmd.c (print_address_symbolic): demangle the symbol.
6262 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
6263 Motorola copyrights in it. Make "make gdb.tar.Z" work.
6264 (alldeps.mak): sort and uniq all results from this; duplicates
6265 hose gdb.tar.Z link building. Remove RCS files from
6266 tconfig and xconfig. Add config files for sun386. Add
6267 a few odd files to OTHERS and HFILES.
6269 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
6271 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
6272 Roll version number to 3.91.5. Make lint work in bindir.
6274 * README: Document cross-debugging and new file structure.
6276 * blockframe.c: Lint. Include "value.h" to declare read_register.
6277 (find_pc_partial_function): remove duplicate line.
6279 * command.h: Lint. Declare error_no_arg and dont_repeat.
6281 * tm-news.h: Remove inadvertently duplicated stuff.
6283 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
6284 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
6286 * config.gdb: Allow `config.gdb host target' form. Clean
6287 up previous change that printed bogus messages when you just said
6290 * core.c: #include "command.h" for lint.
6293 * main.c: Remove some casts of enums. Lint.
6300 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
6302 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
6303 read it from memory. This will allow us to save ptrace calls
6304 eventually. Changed caller single_step too.
6306 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
6307 that we aren't going to use, saving many ptrace calls, especially
6308 when watchpointing or single stepping. Use some #define's for
6310 (store_inferior_registers): Ditto.
6311 (core_file_command): Use some #define's for constants.
6313 * tm-sparc.h: Add #define's for some register numbers, so we
6314 can eliminate the use of random constants in sparc-xdep.c.
6316 * stack.c (frame_command, print_frame_info, up_command,
6317 down_command) Remove frame_changed, since it
6318 causes a bug and doesn't seem to do anything useful. In some
6319 places it was used as a flag, in others as a stack level (?).
6321 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
6322 default is to use the portable (vprintf) version rather than the
6324 * xm-news.h (MISSING_VPRINTF): Add.
6326 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
6328 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
6330 * Remove stuff that forces -Bstatic linking of gdb, and warnings
6331 about linking debugged programs -Bstatic in the sun?os4 config
6332 files in tconfig and xconfig subdirectories.
6334 * main.c (main): Remove unreached exit(0) now that we exit
6337 * Create TODO file for online bug list. There are too many
6338 "little" bugs to keep track of on paper.
6340 * Change Projects file to refer to bug-gdb@cygnus.com
6341 rather than kingdon@ai.
6343 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
6345 * Makefile.dist (VERSION): 3.91.4 now.
6347 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
6348 (condense_misc_bunches): Add sanity check that misc_count is
6349 the same as the number of symbols in the bunch.
6351 * coffread.c: rename init_misc_bunches. Pass an argument
6352 to condense_misc_bunches (a zero).
6354 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
6355 every time we are called; don't rely on our caller to do it.
6356 (add_file): Remove call to init_misc_bunches.
6358 * mipsread.c: Only warn, don't error, if unknown symbol types.
6359 This keeps an old gdb from falling on its face if it sees newly
6360 extended symbol info. Rename init_misc_bunches.
6362 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
6364 * Merge in changes from Per Bothner for DECstations and other
6365 MIPS stuff. The rest is Bothner speaking:
6367 The next message is a merger of Alessando Forin's mips port with
6368 mine. I've tried to use my good if biased judgment to get
6369 the best of both. It *does* need testing.
6371 Some of the changes are general, *not* mips-specific.
6374 Didn't believe in little-endian bit order.
6375 There are still inconsistencies about whether flags
6376 like BITS_BIG_ENDIAN are integer (#if ...) or
6377 boolean (#ifdef ...). I tried to paper over them.
6379 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
6380 Moved some misc_function code that was common to
6381 {dbx,coff,mips}read.c to symtab.c.
6382 In the process, I think I cleaned things up a bit.
6383 At the same time, moved obsavestring and obconcat to symtab.c.
6386 Removed obsolete condense_addl_misc_bunches (use
6387 condense_misc_bunches(1) instead).
6390 Needed to include <sys/dir>, at least on DECstations.
6392 valops.c, mips-tdep.c, tm-mips.h:
6393 Added PUSH_ARGUMENTS macro to support funny argument-pushing
6394 conventions (when STACK_ALIGN is insufficient).
6395 Needed on mips, where doubles need 8-byte alignment,
6396 but ints only need 4.
6399 Removed cruft that was not being used.
6400 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
6403 Print $ before register-names (I think that makes things a little
6405 Never print two instructions, even if one delays.
6406 Removed hex-disassemble set_cmd. (This is not mips-specific,
6407 so I think the argument is whether it is generally worthwhile or not.
6408 I'm inclined to think not, given how easy it is to
6409 convert between radixes in gdb.)
6412 This is basically Alessando's code.
6413 It doesn't use obstacks; I changed it to use obstacks
6414 in a few minor places where using malloc causes a
6415 memory leak. (Probably, more places could/should be changed.)
6416 I added record_misc_function where it was missing.
6417 In symbol_file_command and add_file_command, I tried
6418 to make the code consistent with more recent versions.
6419 Minor sylistic changes in parse_procedure.
6420 Make a .gdbinfo. psuedo-symbol point back to the real
6421 procedure symbol (using the isym field).
6424 This is basically from my port, but with a lot of details
6425 and a number of routines merged in from Alessando's version.
6426 I basically used my code "raw" backtrace (use heuristics
6427 from the actual code, rather than symbol table info) - though
6428 the idea is Alessandro's. I feel my code is a little cleaner
6429 here, particularly in being a little more flexible, such as being
6430 able to handle gcc-produced code (which it now can).
6431 It also doesn't do frame caching (which is not useful
6432 more recent gdb versions).
6433 I also used my code for push_/pop_dummy, more or less.
6434 I tried to incorporate AF's code for testing sigtramp
6435 while backtracing; I probably got it wrong.
6436 Added mips_print_register, which tries to scrunch as much
6437 information as possible on a screen...
6438 Removed the skip-prologue set_cmd. As with hex-disassemble (see
6439 under mips-pinsn.c), I don't see anything mips-specific here,
6440 and I don't see it being all that useful anyway.
6443 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
6444 Use more register names (rather than hard-cases numbers).
6446 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
6448 * Hack up 3.90.11 changes:
6450 * Makefile.dist (depend): parameterize $(GCC).
6451 Add solib.c and solib.o.
6452 (readline): Fix vpath for both absolute or relative SRCDIR.
6454 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
6455 Also, let the part I didn't understand at least compile so
6456 I can test the rest. FIXME.
6458 * dbxread.c: Fix thinko using strcmp.
6459 (init_psymbol_list): declare static.
6460 (partial_symbol_file_open): Comment cleanups better, avoid
6461 cleaning up the string table since the caller will do that.
6462 Move the stat for mod time into symbol_file_command, temporarily.
6463 (There should be a mod time for each symbol file, eventually,
6464 to control its rereading. FIXME.)
6466 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
6467 SunOS, which gives error for shared libs otherwise. (From
6468 Schaefer, probably FIXME needs work for portability.)
6470 * solib.c: Move #include "param.h" to work.
6471 Lowercase all the Uppercase Letters In the Messages.
6472 (find_solib): Clean up inferior_so_name for debug printouts.
6473 Allow no argument, to mean all shared libraries.
6475 * symmisc.c: include param.h to get CLEAR_SOLIB.
6477 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
6479 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
6480 to 3.90.11. ChangeLog entries below are from this.
6482 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6486 * Makefile.dist (HFILES): Add tm-sunos.h.
6488 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6492 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
6494 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
6496 * sparc-opcode.h Added single-operand version of rett.
6498 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6500 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
6501 Put parens around gcc_p in expansion.
6503 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
6505 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
6507 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6509 * Changes for Sun shared libraries:
6510 blockframe.c (find_pc_partial_function): If a non-text symbol
6511 is found, set *address = pc - FUNCTION_START_OFFSET.
6512 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
6513 Disable breakpoints instead of giving an error.
6514 source.c (select_source_symtab): Initialize cs_pst.
6515 symmisc.c: Call CLEAR_SOLIB if defined.
6516 symtab.h: Make text{low,high} CORE_ADDR not int.
6517 (psymtab): New field addr.
6519 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
6520 (record_misc_function): Give correct type for N_DATA symbols.
6521 (condense_misc_bunches): do "misc_function_count = j" regardless
6523 Take code which is shared between symbol_file_command and
6524 add_file_command and put it into partial_symbol_file_{open,read}.
6525 Split add_file_command into add_file_command and add_file.
6526 Make psymtab_to_symtab read in the string table if the file
6528 Two new parameters to read_dbx_symtab and start_psymtab.
6529 tm-sunos.h: New file.
6531 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6533 * infcmd.c: Change cont_command to continue_command and "cont"
6536 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6538 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
6540 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
6542 * values.c (USE_STRUCT_CONVENTION): Check for structures of
6543 size 1,2,4,8 rather than size < 8.
6545 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
6546 as necessary, not just once.
6548 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
6550 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6552 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
6554 * tm-news.h: Add CALL_DUMMY_*.
6556 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
6558 * config.gdb: In list_host, list_target, use ${i}, not $i.
6560 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6562 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
6564 * sparc-opcode.h: Change all store floating-point state register
6565 instructions to have the right match & lose fields.
6567 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
6569 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
6571 config.gdb: If srcdir != ., create readline directory and
6572 copy a makefile into it.
6574 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
6575 consistency with POSIX.
6577 * breakpoint.c (bpstat_stop_status): Disable watchpoint
6578 when we exit its exp_valid_block.
6580 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
6582 * Makefile.dist: Bump version to 3.91.3.
6584 * Clean up handling of breakpoint commands (somewhat).
6585 Prompted by Tiemann bug report "cont 10" doesn't work any more.
6587 inferior.h: Add breakpoint_proceeded to inferior status struct
6588 and globals; save it and restore it.
6589 (clear_breakpoint_commands): Cleanup, remove old #define.
6591 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
6592 (save_inferior_status, restore_inferior_status): handle it also.
6593 (proceed): Remove earlier code that set breakpoint_proceeded.
6594 It is now set only in clear_proceed_status.
6595 (clear_proceed_status): Cleanup, use bpstat_clear rather
6596 than clear_breakpoint_commands. No callers need the stop_bpstat
6597 between clear_proceed_status and proceed.
6599 infcmd.c: Add breakpoint_proceeded definition and comment.
6600 (cont_command, jump_command, signal_command): Move call to
6601 clear_proceed_status right next to call to proceed.
6603 breakpoint.c (bpstat_do_actions): Avoid clobbering our
6604 caller's argument while running down the chain of breakpoints.
6605 Use new variable "breakpoint_proceeded" to determine when
6606 a command that it executes moves the inferior past the
6608 (bpstat_clear): Handle NULL argument.
6609 (bpstat_clear_actions): Avoid useless call to
6610 breakpoint_auto_delete.
6611 (delete_breakpoint): Clean up bpstat's that are pointing to
6612 the deleted breakpoint from the stop_bpstat chain.
6613 (breakpoint_auto_delete): Simplify.
6615 * Clean up handling of EOF, error on stdin, etc. This was
6616 prompted by a network problem that caused gdb to go into an
6617 infinite loop filling up its malloc'd memory.
6619 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
6620 not clear_breakpoints_commands, which is now gone.
6621 (main): If command_loop returns (e.g. from EOF on stdin), do
6622 a quit_command (looping back to command_loop if quit_command
6623 doesn't really quit).
6624 (command_loop): check result from command_line_input and
6625 exit if it returns NULL, rather than passing the NULL to
6627 (gdb_readline): Free malloc'd result space before returning
6630 * utils.c (query): Handle C-d to mean "yes", just as if the
6631 input was not a terminal. Also avoid infinite loop if EOF
6632 occurs in mid-input-line before newline. This allows
6633 query to be used at EOF on stdin with reasonable results.
6635 * infrun.c (proceed): Set breakpoint_proceeded.
6637 * values.c (value_as_long): Avoid infinite recursion for enums.
6638 (_initialize_values): Fix typo in help msg (kingdon).
6640 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
6641 RL_LIB for linking. This allows -lreadline for linking
6642 and nothing for dependencies, once readline is a real library.
6644 * config.gdb: Jim Kingdon: give useful error message if the
6645 host or target type is not recognized.
6647 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
6648 it just defines it. Dumb, but deal with it.
6650 * Jim Kingdon suggests:
6651 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
6653 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
6655 * Makefile.dist (VERSION): Bump version # to 3.91.2.
6657 * Clean up Bothner's changes.
6659 * blockframe.c (clear_pc_function_cache): New function.
6660 * blockframe.c: remake cache_pc_function_* static.
6661 * dbxread.c (symbol_file_command): remove references to
6662 cache_pc_function_* variables.
6663 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
6664 * printcmd.c: Avoid kludging a global variable (addressprint)
6665 to avoid printing the address of a string twice. Instead,
6666 pass the format letter 's' down low enough that it can be seen
6667 to avoid this problem.
6668 (print_formatted): Pass format arg to value_print.
6669 (restore_addressprint): Remove function.
6670 (do_examine): Avoid hacking addressprint, cleanups and such.
6671 (print_frame_args): Add a comment to a Bothner change.
6672 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
6673 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
6674 to wipe out the values cached in blockframe.c.
6675 * symtab.c (find_method): Add comment saying how big you must
6676 allocate to be "big enough". Per being terse again.
6677 * valprint.c (val_print): Handle format letter "s" to print
6678 strings without addresses. Add comment to vtbl printing code
6679 which casts with wild abandon. Rearrange reference-printing
6681 @0xaddr: value (print w/addressprint)
6682 value (print w/~addressprint)
6683 @0xaddr (parameter lists w/addressprint)
6684 or nothing (parameter lists w/o addressprint)
6686 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
6688 * Merge more changes from Per Bothner:
6690 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
6691 annoying) that I tried to improve it. Here are my suggestions.
6693 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
6696 Do automatic de-reference when taking the address of a reference.
6698 Don't deref_ref when printing parameter lists.
6700 More attempts at treating refernences properly.
6702 In val_print, if deref_ref==0, don't print dangling " = ".
6704 Add COERCE_REF macro, which de-references an REF.
6706 * Merge changes from Per Bothner:
6708 * Fixed (Sony news)-specific configuration problems.
6709 * Fixed other problems with using vanilla pcc and libc (enum problems;
6710 assumption that vsprintf exists).
6711 * Some major speed-ups (finc_pc_partial_function now caches a match;
6712 parsing avoids duplicate symbol_lookup calls).
6713 * Changed handling of baseclasses (no longer use baseclasses field
6714 of struct type, use the first n_baseclasses fields instead).
6715 * Various minor changes/fixes, most C++-related.
6718 Cache the most previous match from find_pc_partial_function.
6719 (Save both low and high ends of matching function's pc range.)
6720 This speeds up the loop of infrun.c:wait_for_inferior quite
6721 a bit, and makes step/next commands much zippier.
6723 Added an enum->int cast (otherwise, some compilers barf).
6725 No longer set baseclass offset to 0, since multiple
6726 inheritance now mostly works.
6727 Added a number of casts, to shut up compiler warnings
6728 (after stabs where made enums, not ints).
6729 When discarding a symbol table (in symbol_file_command),
6730 must clear the cache introduced in blockframe.c.
6731 Don't convert $vtbl_ptr_type to vtbl any more.
6732 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
6733 Mask off sign bit emitted by g++ for virtual table offset.
6734 Set voffset to -1 (not 1) for static member functions.
6736 Changed parsing/lexing of names to avoid doing symbol lookup twice
6737 (once when lexing to determine symbol class, once for real).
6738 Now only call symbol_lookup once. Fields of 'this' win especially big.
6740 Subpress printing addr twice in the case of 'x/s addr'.
6742 lookup_basetype_type is no longer used.
6743 Add find_methods as recursive helper function to decode_line_1.
6744 This allows multiple inheritance to work.
6745 Also, once one or more matches has been found, do not look in
6746 base-classes. (Baseclass methods would be overridden, anyway.)
6748 Removed baseclasses array in struct type.
6749 Instead of using baseclasses[i], use fields[i-1].
6750 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
6751 Changed sign convention of voffset (previous was inconsistent).
6753 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
6755 Used to assume existence of vsprintf. Re-written to not need it
6756 if HAVE_VPRINTF is undefined.
6758 typecmp was too pessimistic. Made it less so.
6760 Don't print space after address.
6761 If vtable points to a misc symbol (with 0 offset), print it,
6762 since that indicates the actual class of the object.
6763 Changed ype_print_derivation_info to use new inheritance
6764 scheme (without baseclasses vector).
6766 In value_primitive_field, fixed some bugs left over from previous set of fixes.
6767 Also, changes needed because TYPE_BASECLASSES were removed.
6769 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
6771 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
6774 If there is no path set, and the symbols don't indicate what directory
6775 a file was compiled in, look in the current directory. But either
6776 a path or a known compilation directory will prevent this.
6779 Three independent bug fixes:
6780 * Remove the #if 0 block that breaks some stuff.
6781 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
6782 adapt gdb to either SunOS 4.0.* or 4.1.
6783 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
6786 Instantiate the class T when looking for methods in it. (Tiemann@sun)
6789 (type_print) Demangle the name being printed.
6790 (type_print_base) Handle botched demangling without coredump (tiemann).
6793 (check_stub_method): Document routine.
6794 (tiemann) fix bug for no-arg functions
6795 Avoid clobbering beyond end of malloc'd storage.
6796 Terminate the argument list properly.
6798 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
6800 * Changes merged by John Gilmore:
6803 In breakpoint_1, use new print_address_symbolic instead
6804 of find_pc_partial_function. (This forces use of assembler-level
6805 addresses, and avoids misleading non-mangled source-level names.)
6807 Generalize ansi argument such that -1 means skip arglist totally.
6808 Removed global variable print_ansi_qualifiers (which made
6809 code non-reentrant), in favor of extra explicit arguments
6810 to internal routines.
6812 Add new helper function print_address_symbolic.
6813 Use find_pc_misc_function instead of find_pc_partial_function
6814 (since we want assembler-level symbols here).
6816 Print unknown function as just "f (...)", not "f (...) (...)".
6817 Use new fputs_demangled explicitly.
6819 Fixed a typing violation (problem: value.h cannot be imported
6820 without renaming many variable in this file).
6821 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
6822 decode_line_1: Moved forward some never-reached code.
6823 Made decode_line_2 skip function prologues correctly.
6825 fputs_filtered should not demangle by default.
6826 Add new fputs_demangled to demangle on demand..
6828 Change value_struct_elt to use value_primitive_field (using recursive
6829 utility function search_struct_field). This allows foo.bar to work
6830 for multiple inheritance (so far only for data fields).
6831 Change check_field in the same way (recursive helper function
6832 to support multiple inheritance).
6833 (Note: there are more of these problems that I haven't fixed.
6834 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
6835 value_of_this: 'this' symbol name is now just "this", note "$this".
6837 Don't print static members.
6838 Avoid printing "members of <type>" if there are none.
6839 Simplified type_print_derivation_info by merging duplicate code.
6840 Remove useless blank lines in type_print_base (ptype command).
6842 Added declaration of new routine value_primitive_field.
6844 Added value_primitive_field which is generalized version of
6845 value_field that can handle multiple inheritance (non-zero offsets etc).
6846 Re-implemented value_field to call value_primitive_field.
6848 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
6850 * infcmd.c -- insert else to avoid 'delete env' coredump when you
6851 delete the whole environment. Karl Berry reported the bug.
6852 * source.c - fix openp to avoid //'s in filenames, which
6853 trigger an Emacs bug causing it to not be able to find files
6854 when running gdb in a window.
6855 * dbxread.c - zap the #if 0 that botches the add-file code.
6856 It seems to work a lot better without all the code commented out.
6858 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
6860 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
6863 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
6865 * Makefile - added a ${CFLAGS} to a couple of entries,
6866 added remote-sa.sparc.c
6867 * added remote.sa-sparc.c, a modification of remote.c
6868 which conducts a dialog directly with the SparcStation prom.
