1 Thu Oct 10 17:25:47 1991 John Gilmore (gnu at cygnus.com)
3 * mach386-xdep.c: Even when cross-compiling, leave in the
4 core-file reading code.
5 * core.c (get_core_registers): Avoid coredump if no .reg section.
7 Wed Oct 9 17:03:34 1991 John Gilmore (gnu at cygnus.com)
9 * mipsread.c, coffread.c: initialise TYPE_VPTR_FIELDNO to -1.
10 This avoids coredumps under `set print object on' in value_headof
11 (called erroneously by value_from_vtable_info) for `p &struct'
12 or `p *struct'. From Peter Schauer.
14 Mon Oct 7 00:06:52 1991 John Gilmore (gnu at cygnus.com)
16 * Makefile.in: Roll version to 4.1.2.
17 * dbxread.c: Use aout64.h, not a.out.gnu.h. Get external symbol entry
18 size from BFD (but, FIXME, we don't yet read external nlists's and
19 convert them to internal nlists's before handling them -- we still
20 assume they have the same size and alignment.) Use SET_NAMESTRING
22 * exec.c (exec_file_command): Move dead coff-encapsulation code
24 * m88k-tdep.c, m88k-xdep.c: Remove encap test and #inc <a.out.h>.
26 Fri Oct 4 22:30:06 1991 John Gilmore (gnu at cygnus.com)
28 * configure.in, tm-i386v.h, xm-i386v.h: Intel 386 Mach host port.
29 * xm-i386mach.h, mach386-xdep.c, xconfig/i386mach: New files.
31 Fri Oct 4 17:04:31 1991 Per Bothner (bothner at cygnus.com)
33 More patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
34 * mips-xdep.c (store_inferior_registers): Don't try to
35 write the (pseudo) FP.
36 * mipsread.c (parse_partial_symbols): Improved algorithm for
37 setting pst->texthigh.
39 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
41 * doc/Makefile: make TEXINPUTS include . everywhere
43 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
45 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
46 vestiges of typevectors, which were for symsegs and are no longer
47 used. (From a question by Eliot Dresselhaus
48 <dresselh@RFT30.nas.nasa.gov>).
50 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
52 * dbxread.c, coffread.c: static-ize functions that were
53 gratuitiously external. (From Fred Fish.)
55 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
57 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
58 until it is large enough.
60 * dbxread.c (read_type): Handle error case slightly better.
61 Make complaint message not C++-specific.
63 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
65 * infrun.c (wait_for_inferior): Fix step/next so that you only
66 stop at the beginning of a new line. This fixes various problems
67 with for loops, nested if-else's and switch statements.
69 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
71 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
72 between symtabs and psymtabs become ordinary error()s.
74 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
75 properly, making "end pc" correct in shared lib psymtabs.
76 (From Guy Harris <guy@auspex.com>.)
78 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
80 * dbxread.c: Enable, but soften, const_vol_complaint.
81 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
82 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
83 should be file-scope, not global.
84 (read_struct_type): Remove ancient multiple-inheritance warning.
85 (read_range_type): Check base type, complain & patch if undefined.
86 * stack.c (frame_info): Demangle the function name in `info stack'.
89 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
91 * eval.c (evaluate_subexp_for_address): Don't use
92 TYPE_POINTER_TYPE directly (it might be zero if this type has
93 never had a pointer created before); use lookup_pointer_type.
94 * symtab.c (lookup_method_type): Arguments were swapped in all
95 callers, so fix it here. I'm amazed this worked at all!
97 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
99 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
100 "bss" rather than "data" symbols, but which still conflict.
103 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
104 * core.c (core_files_info): Shorten output.
105 * exec.c (exec_files_info): Ditto.
106 (build_section_table): Ignore zero-length sections.
107 * language.c, printcmd.c: Lint.
108 * language.h (get_frame_language): Declare.
109 * saber.suppress: update.
110 * stack.c (find_relative_frame): Remove complex code that was
111 #if 0'd, stick with simple code. Lint.
112 * saber.suppress: Update a bit.
113 * symfile.c (add_symbol_file_command): Add "?" to question.
114 * utils.c (parse_escape): Avoid \a due to bdead compilers.
115 * value.h: Declare typedef_print.
117 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
120 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
121 (Reported by Mark Peek <mark@imagen.com>.)
123 * solib.c (solib_map_sections): Relocate all sections, even
124 though only the text section's size is tracked. Mark ld_text
125 for eventual elimination as we generalize to N sections.
127 * infrun.c (wait_for_inferior): Don't check if the PC is in a
128 call_dummy if we were stopped by a random signal that is being
129 passed to the program. This produced wierd results when calling
130 functions in the inferior and signals (e.g. SIGALRM) were in use.
132 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
134 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
135 Bugfix from Paul Eggert <eggert@twinsun.com>.
136 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
137 * valprint.c (print_floating): Print 9 digits for IEEE floats.
140 Mon Sep 23 15:50:07 1991 John Gilmore (gnu at cygnus.com)
142 * Makefile.in: Roll VERSION to 4.1.1.

146 Fri Sep 20 16:10:52 1991 John Gilmore (gnu at cygnus.com)
150 * Makefile.in (VERSION): Set to 4.1.
151 * language.c (set_language_command): Print useful help message,
152 and restore the language string after giving help.
153 * valprint.c (typedef_print): Print typedef in C or M2.
154 * symtab.c (list_symbols): Use it.
155 * main.c (main): Avoid any output before (gdb) prompt when -q.
156 * language.c (set_language_command): Handle errors by restoring
157 the language string to its current state (fix from A. Beers).
158 * doc/gdbint.texinfo: Roll in information from README. Rearrange
159 "how to install" and "how to print the doc" stuff so it drops
161 * configure.in: Rename rtpc CPU to romp to match config.sub.
162 * README, WHATS.NEW, TODO: Update for gdb-4.1.
164 Fri Sep 20 17:39:14 1991 Roland H. Pesch (pesch at cygnus.com)
166 * doc/gdb.texinfo: Updates from ChangeLog. set/show write,
167 autoloading shared libs, copyright etc on GDB startup, clean up $_
168 and $__ index refs, set/show listsize and related updates to list
169 cmd. New host/target configs.
171 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
173 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
174 from main Makefile.in version definition
175 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
177 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
179 * doc/gdb.texinfo: merge new language-switching and lang-specific
182 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
184 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
185 compilers (which may lack stddef.h).
187 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
189 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
190 N_WARNING are the same except for the N_EXT bit, so just use their
191 values alone, rather than OR-ing them with N_EXT.
193 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
195 * mipsread.c (parse_lines): Deal with negative extended line
198 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
199 global symbol conflicts.
201 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
203 * .gdbinit: Move 'set complaints' to top, so it runs even in
204 case we aren't debugging GDB.
205 * language.c (_initialize_language): Fix type check and range
206 check documentation strings.
207 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
208 language.c can use it. (Though language.c should really not be
209 handling warnings/errors the way it does, FIXME.)
210 * symtab.c (lookup_primitive_type): const lint.
212 Bugfix from Peter Schauer:
213 * source.c (lines_to_list): Make signed, to avoid comparison
214 going unsigned and complaining that -3 is too high for 21 lines.
215 * stack.c (lines_to_list): Ditto.
217 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
219 * Makefile.in (HFILES): Add minimon.h.
220 (VERSION): Roll version number to 4.0.95.
221 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
222 New rules for building distributions. Normal distribution
223 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
224 one level up from here; it calls make-proto-gdb.dir to build a
225 directory `proto-gdb' which is an image of the release. The old
226 `gdb.tar.Z' rule still works too.
227 * config.sub, configure: Roll in latest from ..
229 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
231 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
232 new-target, and new-config chapters; fix minor typos; come closer
233 to usual GNU markup conventions for @file @samp @code @var.
235 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
237 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
238 * mipsread.c (parse_partial_symbols): Enter the name of all
239 structs/unions... into the psymtab so we can access them if the
240 symtab is not read in.
241 * mips-tdep.c: Remove some unneeded #includes.
242 * xconfig/dec3100: Add HAVE_STRSTR.
244 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
246 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
247 * c-exp.y, m2-exp.y: Lint.
248 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
249 * valprint.c (val_print_fields): Check for stub type.
250 * mipsread.c (_initialize_mipsread): Avoid using
251 builtin_type_void at initialize time.
252 (mipscoff_symfile_read): use it now.
254 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
256 Merge multiple-language support, and partial Modula-2 support,
257 from Andrew Beers <beers@cs.buffalo.edu>.
259 * i387-tdep.c: New file, consolidates most 80387 support,
260 and eliminates host dependency on double<->extended conversions.
261 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

274 (read_dbx_symtab, case N_DEFD): Ignore.
275 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
276 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
277 #if 0 out its uses, though, since they set a dead value.
278 * coffread.c (end_symtab): Use allocate_symtab.
279 (process_coff_symbol): #if 0'd for functions and params as above.
280 (read_enum_type): Recognize Modula-2 BOOLEAN.
281 * symtab.c (add_param_to_type): #if 0'd function to add a
282 parameter type to a function type's field list.

288 hex with local_hex_string for Modula-2 support.
290 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
291 breakpoint condition language-independently.
293 * parse.c: New file with the common code remains of expread.y.
294 * parser-defs.h: New file with common declarations from expread.y.
295 * c-exp.y: New file with the C parser from expread.y, and other
296 language-specific information.
297 * m2-exp.y: New file with the Modula-2 parser and etc.
298 * expread.y, expread.tab.c: Remove.

353 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
355 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
356 entries are enclosed herein. Not all of these changes
357 have been merged into the master GDB sources -- check the
358 ChangeLog above here for the merge log.
360 Mon Jun 3 17:05:45 EDT 1991
362 m2-exp.y Created. Tested outside of GDB for a few days. Proper
363 operators were added, C specific operators and tokens
364 removed. yylex() revamped to some extent. Still things
365 missing from the grammar, such as sets.
366 Tested for two weeks in GDB v3.5.
368 Tue Jun 11 17:23:48 EDT 1991
370 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
371 so they are built-in. Sort of a hack.
373 Fri Jun 14 12:53:51 EDT 1991
375 m2-exp.y Added range checking for numeric constants. Any numeric
376 constant is assumed to be of builtin type INTEGER unless:
377 (1) it is octal or hexadecimal, in which case it is a
378 CARDINAL; (2) it is too big to fit into an INTEGER, in
379 which case it is a CARDINAL.
380 eval.c Added simple range checking for +, -, and * on integers.
381 Doesn't work very well for *, since 6 * 1,000,000,000 =
382 1,705,032,704, which fails the simple test of result >=
383 first_operand, no matter in what order the operands are.
385 Tue Jun 18 14:11:30 EDT 1991
387 Broke the parser into parts, one containing the C grammar and the other
388 containing code to be shared by all of the grammars.
390 The following files no longer exist:
395 The following files were added:
397 c-exp.y (The C grammar)
398 m2-exp.y (The Modula-2 grammar)
399 parser-code.c (Code that is shared by the above grammar)
403 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
404 now necessary to use the Bison compiler compiler, since it
405 will generate function/variable prefixes other than yy.
407 Tue Jun 18 16:47:49 EDT 1991
409 symtab.[ch] Added the external variable working_lang, than holds the
410 value of the current working language.
411 Added the ennumerated type language_mode, with the values
412 language_auto and language_manual, the former meaning that
413 GDB sets working_lang as needed, and the latter meaning
414 that the value of working_lang is totally under user
416 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
417 REAL, BOOLEAN and CHAR. Also added the type codes
418 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
419 utils.c Added set_language_command and show_language_command to
420 implement the GDB support commands "set language" and
422 expression.h A number of identifiers were added to the type exp_opcode
423 to facilitate Modula-2 builtin functions, integer
424 division, and array indexing.
426 Wed Jun 19 13:25:58 EDT 1991
428 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
429 if the language specified by working_lang requires the use
430 of strict typing of expressions. Eventually, even this
431 will be able to be changed by the user.
432 Added the macro RANGE_CHECK, which evaluates to non-zero
433 if the language specified by working_lang requires the
434 checking of a value against the domain of its type.
435 Eventually, even this will be able to be changed by the
437 language.[ch] Predicates involving types (simple_type, ordered_type,
438 same_type, integral_type, numeric_type, character_type,
439 boolean_type, float_type) are added. These predicates are
440 based on the current value of working_lang, and are handy
443 Wed Jun 19 15:39:34 EDT 1991
445 eval.c Added the function type_array_rank which computes the rank
447 valarith.c Added the funtion value_bool, which when given a integer
448 value.h value (ie. struct value *) as an argument, it returns a
449 boolean value (ie. struct value *) true if that integer
450 is non-zero, and a boolean value false otherwise.
451 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
452 will print out properly.
454 Wed Jun 19 16:36:34 EDT 1991
456 valops.c Added the function value_capitalize, which returns it
457 value.h argument capitalized if its argument is a lowercase
458 letter, or the argument unchanged if its argument is not a
460 valarith.c Added the function range_check_p, which returns non-zero
461 value.h if its value argument is between the integral bounds upper
463 Added the function range_check_enum_p, which makes sure
464 that its value argument is a valid member of the domain of
466 Added the function range_check_range_p, which makes sure
467 its value argument lies between the upper and lower bounds
468 of its type argument, which must be a ranged type.
469 Added the function check_array_index, which range and type
470 checks an index of an array.
471 Added the function value_multi_subscript, which computes
472 array[idx1,idx2...idxN], given a value array and an array
473 of values representing indicies.
474 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
475 unpack_long to work with TYPE_CODE_BOOL and
478 Wed Jun 19 18:04:08 EDT 1991
480 symtab.c Stored pervasive types in a structure and make
481 lookup_pervasive_type() a lookup function that was based
482 on working_lang. If lookup_pervasive_type() returned
483 non-zero, then that value was returned (a fix, since
484 before it simply wouldn't return the pervasive type.)
485 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
486 non-zero if the language specified by working_lang means
487 "conversion" when it says "cast".
488 valops.c Added the function value_real_cast(), which performs a
489 value.h *cast*, not a *conversion*, which is what value_cast()
490 does when it can. In particular,
491 value_cast(<float_type>,4) = 4.0, while
492 value_real_cast(<float_type>,4) = some mess.
493 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
494 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
495 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
496 and MIN on integral types. *NOTE*: These are currently
497 hardcoded to work only if there are 8 bits per storage
499 eval.c Made logical functions call value_bool to return a
500 properly typed boolean value, based on working_lang.
502 Thu Jun 20 11:55:27 EDT 1991
504 valprint.c Types now print out in a Modula-2 fashion. This works for
505 the cases when the type is printed out step-by-step, that
506 is, it doesn't work when the name of a structured type
507 (which includes the keyword "struct", etc.) is simply
509 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
510 since type specifications in C and Modula-2 are very
511 different. The C printing of a type is very recursive,
512 whereas in Modula-2 it is generally very simple. C has
513 type prefixes and suffixes, which have no real analogue in
514 Modula-2. Maybe type_print() should call a language
515 specific type printer. This is also advantageous if we
516 compile GDB to exclude some of the languages. We'll just
517 leave those functions out.
519 Thu Jun 20 16:57:10 EDT 1991
521 dbxread.c When reading the complete symbol table in (via
522 psymtab_to_symtab()), the number and types of function
523 arguments are added to a function type. define_symbol()
524 calls add_param_to_type() to accomplish this.
525 Assumption: when we come across a function definition
526 (N_FUN symbol with an 'f' or 'F' in the name), its
527 arguments will appear before another function definition.
528 When a function is found, a pointer to its type is placed
529 in the global in_function_type. Changes that
530 add_param_to_type() makes are to this global.
531 valprint.c The type of a function now includes (for Modula-2) the
532 types of its parameters.
533 eval.c Type checking and a check for the proper number of
534 arguments is now done for function calls. Not sure of the
535 impact this has on C++ member function yet.
537 Thu Jun 20 19:58:48 EDT 1991
539 valprint.c Rewrote the type printer. Broke it into two language
540 specific parts, adding the functions type_print_m2() and
542 An unfortunate consequence is this: if you debugging a C
543 program in Modula-2 mode (why?), info types does not work
544 well with regular expressions, since the types are printed
545 out in Modula-2 terminology, but stored in C terminology.
546 language.[ch] Added the functions new_type_last(), type_keyword(), and
547 type_sep() to aid in the printing of typedefs.
548 symtab.c Made the printing of typedefs as language independent as
549 possible through calls to new_type_last(), type_keyword(),
552 Fri Jun 21 11:50:26 EDT 1991
554 dbxread.c Check all incoming ennumerated types. If it looks like
555 Modula-2's BOOLEAN type, then change the type_code of the
556 type to TYPE_CODE_BOOL so we can process it as a boolean
558 valprint.c Replaced some of the 0x%x with calls to sprintf and
559 hexformat() in val_print().
560 language.[ch] Added the function hex_to_string(), which converts its
561 integral argument to a hexadecimal number (format is
562 language based) and returns the result as a string.
564 Mon Jun 24 12:25:07 EDT 1991
566 valprint.c Some functions call type_print_1() directly, instead of
567 value.h using type_print(), so they can specify where (column) to
568 print things. Since type_print() takes care of language
569 dependence, that needs to be called first. Added a
570 parameter depth to type_print() (so it is now like
571 type_print_1). Changed type_print to type_print_at, and
572 made type_print a macro that passes a depth argument of
574 symmisc.c Changed all calls to type_print_1 to calls to
576 Makefile.dist Made it possible to build GDB for a specific set of
577 depend languages. Do this by passing a definition for the macro
578 LANGS to make. LANGS should be a string containing a
579 space-separated list of language names (ie. LANGS="c m2").
580 The default is to build all languages. Note that grammar
581 files must follow the naming convention of <lang>-exp.y.
582 gdb.lang This holds the current value of the LANGS macro. It is
583 examined every time make is called, and is updated if
585 eval.c Added #ifdef _LANG_<lang> to these files.
586 expread.c Still need to add them to dbxread.c and coffread.c.
594 Mon Jun 24 16:33:11 EDT 1991
596 language.[ch] Added the functions hexformat_pre() and
597 hex_to_string_pre(), which take a prefix argument to
598 include in the format string. Thus, hexformat_pre("08") will
599 return "0x08x" (if the working language is language_c).
600 Made hexformat() and hex_to_string() calls to the above
601 with "" as the prefix argument.
603 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
604 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
605 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
606 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
607 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
608 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
609 valprint.c, vax-pinsn.c
611 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
612 calls to hexformat() and hex_to_string(). Format strings without
613 the leading "0x" were ignored.
615 depend Updated to take the above into account.
618 Tue Jun 25 15:27:18 EDT 1991
620 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
621 and type_check_t to keep track of the current state of
622 range and type checking.
623 main.c Added the variables range_mode, range_check, type_mode,
624 and type_check to record the current state of range and
625 type checking. Added initialization code to main().
626 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
630 Tue Jun 25 17:57:08 EDT 1991
632 dbxread.c process_one_symbol() updates the variable (enum language)
633 source_lang based on the extension of the filename
634 contained in the N_SO sybmol that started this symtab.
635 When end_symtab() is called, the value of source_lang is
636 put into the language field.
637 stack.c select_frame() sets working_lang (and possibly type_check
638 and range_check) to the language field of the symtab
639 associated with the frame that is selected if working_mode
640 is language_auto. If working_mode is language_manual, a
641 warning is printed and working_lang is not set.
642 language.c Added the function set_type_range(), which sets the value of
643 type_check and range_check (if their modes call for
644 automatic setting) based on the current value of
645 working_lang. A non-zero argument will cause the current
646 settings to be output.
649 Wed Jun 26 14:51:40 EDT 1991
651 eval.c Added range checks on assignment.
652 m2-exp.y Added the grammar for sets to the language. Currently,
653 these do not do anything except print an error message.
655 Wed Jun 26 17:01:04 EDT 1991
657 m2-exp.y Added the ability for parse_number() to parse negative
658 numbers. A global flag is set upon encountering a unary
659 minus. This was done to make, for example, 1 parse as a
660 CARDINAL, and not as an integer, per Wirth's examples in
661 Programming in Modula-2 ed.4.
662 valprint.c Added support for "set radix 2" by then setting
663 output_format to 't'.
664 eval.c Implemented range checking on subrange types. Added calls
665 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
666 Implemented MIN and MAX for ennumerated types. The
667 minimum value of an ennumerated type is defined by Wirth
668 as the first identifier, and the maximum as the last.
669 m2-exp.y Made octal numbers ending with "B" be characters and those
670 ending with "C" be numbers, per Wirth's book. (p. 34)
672 Thu Jun 27 14:11:52 EDT 1991
674 stack.c select_frame() now only sets working_lang, it does not
675 notify the user. If working_mode is language_manual, then
676 a warning is issued once.
677 main.c At the end of each call to execute_command(), working_lang
678 is checked against the local static (enum language)
679 current. If they differ and working_mode is
680 language_auto, the new settings of language, type and
681 range checking are printed out.
682 stack.c Modified frame_info() to include the language of the
683 current frame in the output of "info frame".
684 language.[ch] Added the function language_str() which returns the name
685 of the current language.
687 Fri Jun 28 15:33:14 EDT 1991
689 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
690 the language. INCL and DECL currently cause an error,
691 since sets are not implemented yet. INC and DEC are
692 implemented as PREINCREMENT/PREDECREMENT with one
693 argument, and as ASSIGN_MODIFY with two arguments.
694 eval.c Added type checking to the above cases.
695 value.h Added not_lval_constant to the lval_type ennumerated type.
696 not_lval_constant means that the value is a constant
697 value; that is 3 or 'a' or TRUE, not as in a constant
698 identifier. This is used to help coerce numbers such as 3
699 to either signed or unsigned numbers.
700 valops.c Added the function value_coerce_constants() which coerces
701 constant integers as following: if one is a constant and
702 the other is not, the constant's type is set to the type
703 of the other argument. If both are constants and one is
704 signed, the other is converted to a signed constant.
706 Sat Jun 29 17:26:29 EDT 1991
708 valarith.c Added a better range checker. It now checks range
709 (successfully) on integral operations [+-] (signed and
710 unsigned) for any C sized type. Still does not work well
712 int_in_size() returns an integer that is coerced to fit into
713 specified number of bytes.
715 Mon Jul 1 13:04:14 EDT 1991
717 language.[ch] Added the function binop_result_type(), which returns the
718 builtin (struct type *) type that would be the result of a
719 binop on the two values V1 and V2.
721 Wed Jul 3 19:22:53 EDT 1991
723 source.c Extended source_info() to include the source language in
724 the output from "info source".
726 Fri Jul 5 13:48:52 EDT 1991
728 utils.c Moved the support functions for the GDB set/show commands
729 dealing with language into language.c.
730 language.c Added the function language_info(), which displays info
731 about the current working language, type and range check
732 settings. Called via the GDB command "info language".
733 Added an initialization routine _initialize_language(),
734 that sets defaults for the language, type and range
735 variables and sets up the new GDB commands.
736 main.c Language setup moved to language.c.
739 Mon Jul 8 10:10:22 EDT 1991
741 valarith.c Debugged the range checker for arithmetic. Still does not
742 work for multiplication very well.
744 Mon Jul 8 12:40:37 EDT 1991
746 language.[ch] Added the function value_true() which returns non-zero if
747 its argument represents a boolean true value.
748 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
749 check the truth of an expression.
751 Thu Jul 11 12:51:34 EDT 1991
753 language.[ch] Added the predicate structured_type(), which returns
754 non-zero if the argument is a structured type.
755 Added the predicate pointer_type(), which returns non-zero
756 if the argument is a pointer type.
757 eval.c Added the ability to do addition and substraction on
758 pointers and integers. This case simply bypasses the
761 Thu Jul 11 14:41:42 EDT 1991
764 Added the symbol N_DEFD (0x4a) which is a definition
765 module dependency that is used by the GNU Modula-2
766 compiler and the linker. It is not important to GDB,
767 except that [dbx|coff|mips]read.c should ignore these
770 Fri Jul 12 16:07:00 EDT 1991
772 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
773 0 in val_print(). Also added statements to the else part
774 to coerce type (argument to val_print) to a pointer type
775 if it is an "array of unspecified length".
776 valops.c Added the function value_m2_string(), which returns a
777 (value) value which is a constant string, whose type is
778 (ARRAY [0..n] OF CHAR). The length field of the type
779 structure is set to zero, so it will be interpreted as an
780 "array of unspecified length".
781 stack.c Moved the language/frame mismatch check to
782 main.c:execute_command().
783 main.c The working language is recorded each time
784 execute_command() is executed. If working lang has
785 changed during its execution, then the new
786 language/type/range info is printed out for the user. If
787 the working language does not match the language of the
788 frame, a warning is issued.
790 Sat Jul 13 16:16:39 EDT 1991
792 eval.c Moved all the type-checking stuff for operators to
793 language.[ch] language.c. This is so we can keep language-specific
794 stuff (like for what type operators are defined) in
796 language.[ch] Added the function binop_type_check(), which checks to see
797 if its two (value) arguments are type-compatible with its
798 opcode argument. The opcode should represent an operation
799 involving an operator. Also added the macro function
800 unop_type_check, which calls binop_type_check with a
801 NULL second argument.
802 expprint.c Added Modula-2 operators to the op_print_tab, so info
803 expression.h break works correctly. Also added "op_string", which
804 returns the string corresponding to the (enum exp_opcode)
805 opcode that is its argument.
808 Sat Jul 13 18:26:18 EDT 1991
810 coffread.c Added code to record the type of function arguments with
811 each paricular function. Code is very similar to that
813 dbxread.c Moved add_param_to_type() to symtab.c
814 symtab.[ch] Added function add_param_to_type() from dbxread.c
816 *** NOTE: The above additions have not been tested.
818 Mon Jul 15 12:50:47 EDT 1991
820 langauge.[ch] Added the functions type_error and range_error, which work
821 like error() except if the type/range mode is set to
822 *_mode_warn, then they do not do a return_to_top_level(),
823 but merely print a warning.
824 Also changed [set|show]_[type|range]_command() to support
825 the new "warn" feature.
827 Thu Jul 18 17:50:54 EDT 1991
829 mipsread.c Added code to record the type of function arguments with
830 each particular function. Code is very similar to that
833 *** NOTE: The above additions have not been tested.
835 Fri Jul 19 11:19:10 EDT 1991
837 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
838 UMIN_OF_SIZE, which when given a size of a numeric type,
839 return the maximum and minimum value it can hold. UMAX...
840 and UMIN... return the result for unsigned types.
841 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
842 struct types. They call above macros.
843 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
844 avoid a name conlict with the above.
845 c-exp.y Added range checking on numeric constants in
846 parse_number() for completeness.
847 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
848 return 0 if working_lang is not language_c.
850 Thu Aug 8 14:17:22 EDT 1991
854 breakpoint.c Documentation strings of some commands changed to
855 eliminate the references to the C language where
858 Tue Aug 13 15:48:03 EDT 1991
860 m2-exp.y Added qualified identifiers to the grammar. The semantics
861 are slightly different from those of the GDB operator ::
863 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
864 type_exp, where type_exp is any valid type expression.
866 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
867 printcmd.c Modified ptype_command() so it actually parses the input
868 (necessary for type expressions with scope qualifiers).
869 Added the function ptype_eval() which expects an
870 expression composed of one OP_TYPE element.
871 *.[ch] Replaced all occurences of parse_c_expression with
873 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
875 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
877 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)

881 * infrun.c (child_attach): Lint.
882 * solib.c (find_solib): Handle shared libs version 2.
884 Small fixes from David Wood:
886 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
890 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
891 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
893 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
894 chars_per_line is at maximum (user typed `set width 0'). Fix
895 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
897 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
899 * coredep.c: include ptrace.h where necessary.
900 * mipsread.c(parse_lines): fix unsigned char problem that was
901 messing up line numbers on SGI's and possibly other MIPS based
903 * infrun.c (child_create_inferior): use better test to check
904 return val from setpgrp().
905 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
906 for sgi/irix support.
908 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
910 * mipsread.c (parse_symbol): Put non-static procedures

915 Patch together `text_start' and `text_end' for 29K port.
917 * exec.c (exec_command): If NEED_TEXT_START_END, define the
918 variables and set them based on the exec file.
919 * am29k-tdep.c: declare text_start.
920 * valops.c (call_function_by_hand): declare text_end.
922 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
923 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
924 because machines that do this will also have to know to
925 set NEED_TEXT_START_END. Besides, it was a redundant way to
927 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
928 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
931 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
933 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
935 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
936 Pass MUNCH_DEFINE to munch whenever we run it.
937 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
938 format string; use 0x%x instead.
939 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
940 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
941 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
942 * inflow.c: Handle `short' process group IDs.
943 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
944 and check for ptrace errors.
945 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
946 (coff_symfile_init): Initialize text_bfd_scnum.
947 (read_coff_symtab): Use it to find the text [and absolute?] sections.
948 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
949 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
950 Merge target arm case with other "easy" cases. Add target
951 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
952 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
954 * minimon.h, remote-adapt.c, remote-mm.c: Add.
955 * munch: Cope with RT/PC putting fns in data segment.
956 Restore ability to override `nm' by specifying MUNCH_NM.
957 * xconfig/rtbsd, xconfig/ultra3: New host systems.
958 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
959 and remote-adapt. Remove encapsulated coff #define's (the
960 support should go in BFD, and gdb shouldn't know or care).
961 * tconfig/a29k-kern: Same, but for remote kernel debugging.
962 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
963 * tm-29k.h: Update BADMAG (though it should go away).
964 Allow the register definitions to be overridden in another
965 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
966 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
967 DUMMY_SAVE_GR96, for handling kernel calling conventions
968 that use GR64+ rather than GR96+.
969 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
970 remote debugging of Ultra3 kernel. Includes tm-29k.h and
971 overrides various things.
973 * remote-mm.c (mm_attach, mm_wait): Handle attach like
974 child_attach does, making a clean stop in the newly attached
978 * coffread.c: Make coffread independent of any particular
979 variant of COFF. Avoid #include-ing any particular one except
980 internalcoff.h. BFD now passes key values for symbol reading
981 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
982 and the symbol masks and shifts); use them.
983 Remove obsolete end_of_text_addr.
985 * exec.c: Remove unused include files.
987 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
989 * Makefile.in (documentation targets): Pass $(M4).
990 Bugfix from eggert@twinsun.com (Paul Eggert).
992 * stack.c (down_silently_command): Check for stack existence.
994 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
996 * Makefile.in (VERSION): Update to 4.0.3.
998 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
1000 * core.c (core_file_command): Print frame at coredump with
1001 its level number, by calling print_stack_frame.
1002 * frame.h: Add selected_frame_level, print_stack_frame.
1003 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
1004 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
1005 Change print_sel_frame and print_selected_frame callers to
1008 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
1009 * symfile.c (free_named_symtabs): Ditto.
1010 * main.c (main): wrap_here needs an arg.
1011 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
1012 (solib_add): Avoid noise.
1013 (solib_create_inferior_hook): Lint.
1014 (sharedlibrary_command): Move dont_repeat to here.
1015 * utils.c (error): Call wrap_here to force buffered output.
1017 Small patches from Peter Schauer:
1019 * coffread.c (start_symtab): Free any existing line_vector before
1021 (read_coff_symtab): Ditto for type_vector.
1023 * source.c (lines_to_list): New variable, replacing function.
1024 (all uses): Use as variable.
1025 (_initialize_source): Add 'set listsize' and 'show listsize'.
1026 * utils.c (lines_to_list): Remove function.
1027 * stack.c (print_frame_info): Use as variable.
1028 * defs.h (lines_to_list): Remove declaration.

1032 * breakpoint.c (insert_breakpoints): Restore warning about
1033 the program might be running in another process, but only for
1034 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
1035 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
1037 * utils.c (error): if error_pre_print is set, print the string
1039 * main.c (main, print_gnu_advertisement, print_gdb_version):
1040 Reformat legalese so it always prints, but acts as an "I'm here"
1041 message while symbols are being read. If any errors occur,
1042 print a few newlines to set off the message and start it at the
1043 left margin. Remove mention of "help" command, and don't yak
1044 about symbol reading.
1045 (catch_errors): Error string is now printed first in case of
1047 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1048 suggest the "help" command.
1050 * Makefile.in (VERSION): Set to 4.0.2.
1052 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1054 * .gdbinit: Remove useless "rr" command. Set complaints
1055 to 1 for people debugging gdb.
1057 * breakpoint.c, remote-vx.c: Reword strings printed by
1058 catch_errors callers.
1060 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1062 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1063 (Fix from kenc@viewlogic.com.)
1065 Fix some infrastructure to be able to cope with host and target
1066 machines with different sized basic types (ints, ptrs, etc).
1067 (Idea from pierre@la.tce.com (Pierre Willard).)
1069 * values.c (value_from_longest): Rename from value_from_long.
1070 Handle pointer types as well as integers, so that targets with
1071 different pointer sizes from the host can be accomodated.
1072 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1073 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1074 uses of value_from_long to value_from_longest.
1075 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1076 the correct pointer type to value_from_long{est}.
1078 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1080 * remote-vx.c: Remove obsolete code for calling functions via
1081 vxworks kludge interface (it referenced value_from_long).
1083 * valops.c (value_string): Find malloc with lookup_misc_func, not
1086 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1088 Make writing to files work properly. (Fixes to BFD are also needed.)
1090 * core.c (core_open): Open file ourselves, read or r/w, depending on
1091 write_files. Use bfd_fdopenr.
1092 * gdbcore.h (write_files): New variable.
1093 * exec.c (write_files): Define variable, add set&show for it.
1094 (exec_file_command): Use write_files to open for read or r/write.
1096 Make shared library reading happen automatically. These changes
1097 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1099 * inferior.h (stop_soon_quietly): Add to exported variables.
1100 * infrun.c (child_create_inferior): call solib hook, if defined.
1101 (child_attach): call solib hook, if defined.
1102 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1103 (find_solib): Use lookup_misc_func rather than hand-rolled.
1104 (symbol_add_stub): New stub for catch_errors.
1105 (solib_add): Avoid output if !from_tty. Catch errors rather
1106 than just calling symbol_file_add and bombing.
1107 (solib_create_inferior_hook): Interface with the target process
1108 to let it read and alloc shared libs, then figure out what it did.
1110 * core.c (validate_files): Fix typo, soften warning.
1111 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1113 * utils.c (fputs_demangled): Avoid duplicate printing if
1114 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1116 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1117 (Fix from pierre@la.tce.com (Pierre Willard).)
1119 * main.c (catch_errors): Change argument to a char * from an int,
1120 since a char * can point to a struct full of glop, but an int
1121 is not guaranteed to be able to hold a pointer.
1122 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1123 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1124 * core.c (core_open, solib_add_stub): Adapt.
1125 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1127 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1129 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1130 by adding .NOEXPORT target.
1132 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1136 * Makefile.in (VERSION): Roll to 4.0.
1137 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1139 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1141 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1144 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1147 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1149 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1150 reflect above name change
1152 * WHATS.NEW: correct pointer to refcard.
1154 * doc/gdb.texinfo: update New Features, Installing
1156 * doc/gdbint.texinfo: add short description of configure +template
1158 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1160 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1162 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1164 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1165 tar file, add dependencies for referenced doc files.
1167 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1169 * coffread.c, symfile.c, stack.c: saberized.
1171 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1173 * doc/refcard.tex: permuted Essential Commands sec
1175 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1177 set/show symbol-reloading
1178 default set complaints 0
1180 RET-repeat disabled after prompted long displays
1181 processID (attach) interpretation of 2nd GDB cmdline arg
1183 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1185 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1186 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1187 breakpoint.c, main.c: lint.
1189 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1191 Install new configuration scheme for GDB and friends.
1193 * config.sub: Translate ordinary names to three-part names.
1194 * configure: Use three-part names internally.
1195 * configure.in: Translate three-part names to filenames.
1197 * README, WHATS.NEW: Update for gdb-4.0.
1198 * Makefile.in: Roll VERSION to 3.99.
1200 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1202 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1203 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1204 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1205 to single structures rather than arrays; when passing
1206 their address, use &. This avoids trouble with bdead compilers.
1207 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1208 instead. This avoids portability headaches.
1209 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1211 * source.c (open_source_file): Avoid ANSI const bdeath by
1212 skipping declaration and then casting result value.
1213 * tm-hp300bsd.h: Clarify comment.
1214 * utils.c (strstr): Result is const char *; ANSI bdeath.
1215 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1216 since system include file defines it differently from "defs.h",
1217 though the two are equivalent for our purposes.
1218 * tconfig/hp300bsd: Add m68k-tdep.o.
1220 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1222 * tconfig/sun*4: Remove warnings about system assembler.
1224 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1226 * mcheck.c: Avoid warning about undeclared abort fn.
1227 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1228 it causes recursive calls to error() when used in cleanups.
1229 To do so requires that we make it a function, so we do.
1230 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1231 * utils.c (do_cleanups): Remove the current cleanup from the
1232 chain *before* calling it, in case error() is called from it.
1233 The result won't be pretty, but won't be an infinite loop either.
1235 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1237 * dbxread.c (read_struct_type): Grok anon structs for C++.
1238 (vb_name, vptr_name): Null terminate these strings.
1240 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1242 Minor bug fixes from BSD Net2 gdb:
1244 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1245 returns 0, there is no previous frame.
1246 * breakpoint.c (commands_command): If !from_tty, don't call
1247 input_from_terminal_p().
1248 * dbxread.c (record_misc_function): Speed up slightly.
1249 (compare_psymbols): Ditto.
1250 * infcmd.c (do_registers_info): Take a second argument to
1251 determine whether to print float registers. "info registers"
1252 does not do so anymore. "info all-registers" does, now.
1253 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1255 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1256 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1260 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1261 executing_breakpoint_commands if we are interrupted by error.
1262 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1263 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1264 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1265 catch_errors() so we can setup the frame regardless of whether
1266 the shared libs work.
1267 * ieee-float.c (double_to_ieee_extended): Get exponent from
1268 right place in little-endian systems. From John Carey.
1270 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1272 * main.c: Remove unused terminating_signals and catch_termination().
1273 (long_options): Terminate with a zero element.
1274 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1275 (gdb_readline): Make call-compatible with readline.
1276 (init_signals): Improve comments re vfork vs. signal.
1278 * utils.c (prompt_for_continue): Use new gdb_readline().
1279 If we prompt for continuation, we don't let CR repeat the previous
1280 command, once we get back to a prompt. It's too easy to keep
1281 hitting CR, expecting "--more--" prompts, and have some long
1282 command start repeating on you.
1284 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1286 * blockframe.c (frameless_look_for_prologue): Speed up by
1287 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1288 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1289 Define two variants, one faster.
1290 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1291 and return zero, rather than giving an error.
1292 (setup_arbitrary_frame): Initialize the PC in the new frame.
1293 (skip_prologue): Add a second arg saying whether we're just
1294 checking for a frameless function or not.
1296 * core.c (core_open, core_close, core_xfer_memory): Move
1297 section table pointers and bfd* into the target_ops.
1298 (core_open): Allow errors in shared lib reading, etc.
1299 (core_files_info): Describe shared library sections.
1301 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1302 exec_files_info, set_section_command): Move section table
1303 pointers and bfd* into the target_ops.
1304 (add_to_section_table): Add BFD to section table.
1306 * target.c (target_xfer_memory, target_info): Pass target to
1307 xfer_memory and target_info functions.
1310 * gdbcore.h: Move struct section_table.
1311 * target.h: New home of struct section_table.
1313 * solib.c (solib_add): New argument is the target_ops whose
1314 section list is to be added to, if any. Reallocate the
1315 sections in that target to add any that come from shared libs.
1316 (throughout) so_sections renamed to sections.
1317 (solib_xfer_memory): Deleted.
1318 * tm-sunos.h (SOLIB_ADD): Add target argument.
1319 (SOLIB_XFER_MEMORY): Delete.
1321 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1322 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1323 from target_ops. It's the same on all targets. Add two section
1324 pointers to target_ops.
1326 * stack.c (find_relative_frame): Dump ancient algorithm for
1327 "down", just use handy "next" pointers.
1328 (frame_command): Don't error if there is no stack; let user
1331 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1332 modifies static state in the parent process; new_tty itself
1333 runs in the child and modifies the child's file descriptors
1334 to match the saved static state.
1335 * infrun.c (child_create_inferior): Call new_tty_prefork,
1338 * infptrace.c (child_xfer_memory): Add ignored target arg.
1339 * remote-eb.c (eb_xfer_inferior_memory): ''
1340 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1341 * remote-vx.c (vx_xfer_memory): ''
1342 * remote.c (remote_xfer_memory): ''. Rename from
1343 remote_xfer_inferior_memory.
1345 * main.c (main): Only try to attach "corefile" argument if
1346 it starts with a digit.
1348 * symfile.c (symbol_reloading): New "set/show" variable.
1349 (symbol_file_add): Shorten message about symbol reading.
1350 (add_symbol_file_command): Merge with add_syms_addr_command,
1351 since this should work on all targets now.
1352 (stop_whining): Default to zero, to shut up complaints
1353 about bad symbol tables on many systems.
1354 (free_named_symtabs): Just exit unless symbol_reloading.
1356 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1357 and add comment explaining shared library screw.
1359 * source.c: #if defined => #ifdef.
1361 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1363 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1365 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1367 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1368 (doc/Makefile knows how to make one for local config)
1370 * Makefile.in: use doc/Makefile for doc targets
1372 * doc/Makefile: GDB documentation now has its own Makefile
1373 doc/refcard.tex: renamed from "gdbrc.tex"
1374 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1375 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1378 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1380 * values.c (baseclass_addr): When reading target memory, use the
1381 length of the basetype, not the upper type. We've only malloc'd
1382 enough space for the basetype, leading to errors in free().
1384 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1385 ends up as a function specially, since we know the actual type of
1386 the pointed-to address. This (somewhat) fixes display of
1387 expressions that include misc_function_vector names. Try `cond 1
1388 !strcmp("a","b")' then `i b'.
1390 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1391 The child can be proceeded from inside wait_for_inferior in
1392 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1393 getting skipped in that case.
1395 * expprint.c (print_subexp): Use filtered output, since the
1396 subroutines we call use it, otherwise the output is horribly
1397 mangled, since output of wrappable stuff comes out late.
1399 * Makefile.in: Bump VERSION to 3.98.1
1401 * infrun.c (child_create_process): Use execlp to find the
1402 shell to exec our target program. This requires some fiddling
1403 with `environ' since there is no execlpe().
1405 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1407 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1408 Minor rearrangement of refcard permits two new make targets--
1409 gdbrc.dvi DVI output for refcard, using CM fonts
1410 gdbrc.ps PostScript refcard, using PS fonts
1412 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1416 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1417 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1419 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1421 * doc/gdb.texinfo: last changes for release.
1422 Minor typo and formatting fixes; incorporated most fixes remaining from
1423 filed mail commenting on earlier drafts.
1425 Added warnings: pipes don't work in run command;
1426 conditions are converse of assertions;
1427 step over fn without debug info goes to next fn;
1428 vars may have "wrong" values near fn entrance, exit
1430 Added example from Kingston on printing repeated nonadjacent values
1432 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1433 shell mode for signals
1435 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1436 doesn't sound so much like its parent "Stopping and Continuing"; also
1437 moved entries on continue to top of section, so they don't get lost.
1439 Improved installation directions in appendix, added manual formatting
1442 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1444 * configure.in: Remove xm.h and tm.h even if we aren't linking
1445 new ones, so "./configure sun4; ./configure none" does the right
1446 thing. Assume that alldeps.mak and depend are already built in
1447 srcdir, and avoid running "make" (particularly "make depend",
1448 which involves "gcc") from inside configure. Build Makefile
1449 directly rather than building Makefile.conf first.
1450 * configure: Regenerate with above changes.
1451 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1452 to 3.98. Revise gdb.tar.Z procedure to produce a file
1453 called gdb-$(VERSION).tar.Z but which unpacks into a
1454 directory called "gdb". Move non-source files out of
1455 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1456 (depend): Don't try to do "gcc expread.y".
1457 (expread.o): Update dependencies by hand.
1459 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1462 Fixed a variety of small typos that prevented info from formatting
1463 cleanly; altered too-long heading for GPL Appendix, as discussed
1464 w/RMS; Changed date on cover to July 91.
1466 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1469 (1) Applied some fixes due to comments from Larry Breed (easier ones
1470 through chapsec 5.2)
1471 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1472 it's broken in latest texinfo
1473 (3) Introduced *some* use of [] for optional arguments, where
1474 explanation is not simpler by listing cmd w arg and cmd w/out arg
1475 separately. Still not using @deffn.
1476 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1477 couple of headings are too long. Need patches to texinfo or revision
1480 * Partial update to README (which still needs work for this
1481 release!): (1) use of configure corrected for new script,
1482 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1484 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 * symtab.c (lookup_symbol): Don't complain right off about
1487 no debug symbols; use the misc function vector first.
1488 (list_symbols): Use misc function vector to find symbols
1489 that don't have debug info, and print them.
1490 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1491 PC range doesn't match symtab PC range, as it does on the
1492 MIPS because our symtab reading isn't perfect.
1494 * dbxread.c (dbx_symfile_read): Make warning about
1495 "no debug symbols" slightly nicer.
1497 * source.c (select_source_symtab): If "main" symbol exists,
1498 but decode_line_spec can't find line info, don't just return
1499 a zero; try other source symtabs or give an error.
1501 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1502 their low addresses first, then rip through fixing high addrs.
1504 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1505 <runene@ifi.uio.no>.
1506 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1508 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1510 * Minor, mostly mechanical, cleanup of doc subdir for clean
1511 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1512 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1514 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1516 Mostly MIPS and general symbol-reading fixups.
1518 * doc/gdbint.texinfo: Add documentation on symbol-reading
1521 * mipsread.c: Remove kludges around #include "ecoff.h".
1522 Remove redefinitions of a_magic, etc, no longer used.
1523 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1524 Fix global overview comments to match symfile.c protocol.
1525 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1526 (mipscoff_symfile_read): Eliminate unused code. Avoid
1527 sorting all the symtabs, when all we have read here is psymtabs.
1528 The symtabs are sorted as they are created anyway. Tell
1529 condense_misc_bunches whether we're mainline.
1530 (psymtab_to_symtab_1): Pass filename when recursing, to make
1531 stack trace more informative.
1532 (parse_partial_symbols): Assume cur_hdr as argument.
1533 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1534 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1535 the TYPE_NAME of char *, since that's done in symfile.c.
1536 (free_numargs, parse_symbol, add_symbol, add_block,
1537 shrink_linetable): Declare these fns void.
1538 (upgrade_type): Convert tree of if's to switch. Clean up
1539 bogus "off == 0" handling with a complaint. Avoid setting
1540 field bitpos and bitsize of array with lower and upper bounds.
1541 Check specified bitsize of elements against their actual type's
1542 bitsize, and complain if different. Complain about unknown
1544 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1545 (psymtab_to_symtab_1): Print names of subsidiary files that
1546 are being read in. FIXME, we read far too many files. This code
1547 is not the problem, the problem is in parse_fdr where the psymtabs
1549 (cross_ref): Result should indicate that we used one aux entry
1550 normally, or two if we encountered a "next" entry. This used
1551 to leave the caller pointing at the wrong aux entry.
1552 (add_symbol): If overflowed cur_block, reallocate it larger,
1553 chase all pointers to it, and complain(), rather than clobber memory.
1554 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1555 (new_field): Only allocate one field initially, not two.
1556 Pull ++ out of macro argument. Simplify.
1557 (_initialize_mipsread): Avoid initialization of importd
1558 global_psymbols and static_psymbols.
1560 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1561 to properly set pst->symtab; avoid searching for it.
1562 (symfile_fns): Improve comments, add a FIXME.
1563 * dbxread.c: Update comments to reflect symfile protocol.
1564 (read_ofile_symtab, end_symtab): Return the symtab.
1565 (psymtab_to_symtab_1): Set pst->symtab.
1567 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1568 whether we're mainline.
1570 * symfile.h (sym_fns): Remove unused sym_discard member.
1571 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1573 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1574 the environment variable is not.
1575 * infcmd.c (finish_command): Use filtered printfs.
1576 * cplus-dem.c: Add struct tags to a few unnamed structs.
1577 * valops.c (value_coerce_array): Improve comments.
1578 * valprint.c (type_print_varspec_suffix): Print array size only
1579 if greater than zero.
1580 * m88k-tdep.c: Shift some lines left by one space, that had
1581 apparently been trashed at some point.
1582 * TODO: More things to do, a few got done.
1584 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1586 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1587 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1589 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1590 * expread.y, findvar.c, symmisc.c: Ditto.
1591 * printcmd.c (address_info): Update printed forms of LOC_
1592 symbols. Elim LOC_EXTERNAL.
1593 (print_frame_args): Keep track of param stack offsets before
1594 re-looking up to find the local register param is kept in.
1596 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1597 Further integration of mipsread into gdb. Eliminate unused
1598 routines, duplicate declarations. Handle static symbols in
1599 psymtabs as well as external symbols. When reading symtabs,
1600 insert symbols into the correct block (global, static, or a local
1602 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1604 (mipscoff_symfile_read): Don't call select_source_symtab.
1605 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1606 rather than SYMBOL_VALUE.
1607 (parse_external): Comment clobbering of top_stack.
1608 (parse_partial_symbols): Update comments. Allocate and parse
1609 static symbols as well as external symbols. FIXME, enum values
1610 are not handled in this pass, but should be. Inline new_psymbol.
1611 Use SYMBOL_VALUE_ADDRESS.
1612 (psymtab_to_symtab_1): Read symbols into global static block
1613 by default (until enter some function's local block context).
1614 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1615 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1617 * source.c (select_source_symtab): Select a source symtab
1618 from either the symtabs or, failing that, the psymtabs.
1619 (list_command): Update error message.
1620 (forward_search_command, reverse_search_command): Use getc, not
1621 fgetc, for speed. FIXME, add comment about buffers that die if
1622 overrun by long line.
1624 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1625 by an entire word, which is not portable, if we have a 32-bit
1626 field. (Code in dbxread.c already turns such bitfields, if
1627 aligned, into ordinary ints, but fixing this will help for other
1628 symbol formats and for future changes.)
1629 * core.c (core_open): Handle ANSI const brain death.
1630 * utils.c (vprintf): Fix varargs typo.
1632 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1634 * findvar.c (find_var_value): Handle &function better.
1635 * TODO: Document work needed on &fn and &array.
1636 * printcmd.c (print_address_symbolic): New arg is the prefix
1637 to print if a name is printed.
1638 (print_address_demangle): Honor "set print address" now.
1639 Use new arg above to improve spacing of output.
1640 * valprint.c (val_print): When printing function pointers,
1641 print symbolic form too.
1642 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1644 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1646 * core.c (memory_error): Reword error msg to mislead less.
1648 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1650 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1651 parse_partial_symbols): Use newer BFD internals (external_filehdr
1652 and external_aouthdr), byte-swap the fields that we care about
1653 before using them, and make the file header data local to
1654 read_the_mips_symtab rather than global.
1656 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1658 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1659 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1661 * main.c (command_line_input): Flush stdout and stderr
1662 before every call to readline. This reportedly fixes a bug
1663 that comes up in Sys V running emacs-gdb and/or xxgdb,
1664 when stdin/out are pipes or sockets.
1666 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1668 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1669 Avoid declaring Makefile dependencies, because GNU Make stupidly
1670 tries to update it if we do.
1672 * coffread.c: Revise for minor changes to bfd internal coff
1675 * configure: If -template= is given a relative path, make it
1676 absolute before recurring in subdirectories.
1678 * configure, configure.in, Makefile.in: Install "configure" script
1679 as replacement for config.gdb.
1680 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1681 * README: Update for configure, mostly. FIXME.
1683 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1684 target config files that they are for the host. When the lines
1685 get copied into the Makefile, this makes it more obvious what's
1688 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1690 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1691 tabs, which end up in the disassembler output inadvertently.
1693 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1695 Make it compile cleanly in an ANSI GCC2 environment.
1697 * blockframe.c: <stdio.h>
1698 * cplus-dem.c: free takes a void *, ifdef __STDC__
1699 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1701 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1702 * stddef.h, stdlib.h: Remove these files.
1703 * symtab.c: Avoid declaring qsort, close.
1704 * symfile.c: Avoid declaring close.
1705 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1706 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1708 Assorted other changes.
1709 * dbxread.c: include "libaout.h", not "liba.out.h".
1710 * printcmd.c (print_frame_args): Set recurse properly for
1711 indentation of struct and array parameters.
1712 * valops.c (value_cast): Allow cast to void.
1713 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1714 single_step() in a target-independent fashion.
1715 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1716 set up to be ready to continue. This makes us target independent.
1717 * infptrace.c (child_resume): Remove call to single_step; now
1718 can single step a SPARC target of any kind.
1720 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1722 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1723 docn into separate sections---basically chapters, plus two loose
1724 pieces that can be configured to go in different places. This
1725 allows GNU m4 to preprocess the manual without coredumping.
1727 * Makefile.dist: tell TeX where to find texinfo.
1729 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1731 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1732 the new target "rdl-apps.texinfo" which captures the Makefile
1733 variable that records where to find the Readline libraries.
1735 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1737 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1738 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1739 * defs.h (const, volatile): Only define if not already defined.
1740 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1742 * README: Update for release 3.95.
1743 * config.gdb: Don't create readline dir in subdir builds.
1744 * main.c: Include with "..." form for non-system include files,
1745 so "gcc -MM" for "make depend" works.
1746 Include readline files with "...h" rather than <readline/...h>.
1747 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1749 * coffread.c: Undo minor damage done by Rich Pixley. Use
1750 different internal and external representations of COFF
1751 data structures. Use new BFD routines for swapping them in and
1753 * symfile.c (free_named_symtabs): Avoid freeing file names that
1754 are null or empty. Old i960 tools seem to produce files that
1755 claim to have empty names, causing each successive file read
1756 to blow away the previous one.
1757 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1758 Move deferred_stores to top of file, but don't separate its
1759 #define's from its variable. Add commentary.
1760 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1761 favor of keeping the (working) config.gdb. Move readline
1764 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1766 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1768 * infptrace.c (fetch_registers): no result, since now void.
1769 * tconfig/news: target depends on m68k-tdep too.
1771 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1773 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1776 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1777 applied various small fixes due to or inspired by RMS comments
1779 * doc/gdb.texinfo: finished using all RMS comments, save those for
1780 appendices on readline and cmd history (which are in other source
1783 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1785 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1786 chapter 9; (2) documented 'break' command's menu mode for
1787 overloaded names, in response to hgs problem report C++ p-31
1789 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1791 * doc/gdb.texinfo: (1) better introductory example; (2) more
1792 consistent use of @code, @samp, @file, @kbd throughout; small
1793 cleanups to first three nodes; (3) new "Contributors" node;
1794 (4) Appendix, Renamed Commands; (5) divert specialized startup
1795 instructions to "Targets" chapter for generic manuals, while
1796 leaving them up front for manuals specific to specialized
1797 environments; (6) apply fixes from RMS comments through chapter 4.
1799 * pretex.m4: modify explanatory text slightly (and redefine
1800 "regexp") to keep GNU m4 from complaining. (It still crashes
1801 later, but one step at a time...)
1803 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1805 * readline/readline.c (update_line): Avoid dereferencing a pointer
1806 before comparing it to its bounds. Saber caught this.
1807 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1808 and only set PC if tgetstr returned non-null. Saber caught this.
1810 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1812 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1813 stuff for config manual) here where it counts; updated
1814 to use new subdir structure (gdb/doc/).
1816 * Makefile: generated from above via
1820 * gdbint.texinfo: added instructions on generating gdb.info* files
1821 locally for release. These are ordinary info
1822 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1823 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1824 to generate these, so we distribute them already formatted.
1826 * gdb.texinfo: included full Info node and menu crud (as generated
1827 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1829 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1830 put in comments-for-future gdb.info target (one day makeinfo will
1833 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1835 * gdb.texinfo: Updated to include new or old undocumented
1836 commands, at least the following (perhaps some others I forgot to
1837 record): info f, info float, info path, info program, info s, info
1838 set, info source, info terminal, info types, info user, set/show
1840 Also covered all recent GDB command renames for v4.
1842 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1844 * mipsread.c: Rather than keeping count of how many symtabs
1845 and psymtabs we have, for sorting purposes, count them when
1846 we need to sort. This fixes bug in rereading of symbol tables.
1848 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1850 * infcmd.c: renamed "info path" to "show paths"
1851 * gdbrc.tex: documented above.
1853 Wed May 8 04:51:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1855 * remote.c: Fix comments.
1856 * utils.c (error): Force out any pending wrap output.
1858 Sat May 4 11:11:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1860 * Makefile.dist: Roll VERSION to 3.95.
1861 Fix up "saber_gdb" to work again.
1862 * saber.suppress: Update.
1864 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1865 symtab.h, target.c, target.h: Lint.
1866 * core.c: setup and select frame after reading shared libs,
1867 else reading shared libs will clobber them. Lint.
1868 * utils.c (error): Force out any buffered wrap text.
1870 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1872 * remote.c: Remove decls of memory_insert_breakpoint
1873 and memory_remove_breakpoint, no longer used. (Suggestion of
1876 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1877 to make it easier to interface to "configure"'d libraries.
1879 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1881 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1882 aliases for set/show print.
1884 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1924 * {x,t}config/m88k ({X,T}DEPFILES): Add missing files.
1926 * mtrace.c: Don't typedef things like size_t, just #define them.
1928 * coffread.c [TDESC]: #if 0 out references to coffsyn.
1930 * symtab.h (struct symtab): Include EXTRA_SYMTAB_INFO.
1931 tm-88k.h: Define EXTRA_SYMTAB_INFO.

1934 dc_dcontext_t not int.
1936 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1938 * coffread.c [TDESC]: Move setting of debug_info from
1939 coff_symfile_read to find_linenos and make it work with BFD.
1941 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1943 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1945 * utils.c (strsave): Make arg const char* not char*.
1947 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1966 Thu May 2 17:53:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1968 Mips bringup and general cleanup
1970 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1971 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1972 (This still doesn't seem to make MIPS bkpts work.)
1973 * mipsread.c: Remove dup "Reading symbol data..." msg.
1974 (symbol_file_command, add_file_command): Remove, obsol.
1975 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1976 Wrap output appropriately.
1977 * stack.c (locals_info, catch_info, args_info): Check
1978 selected_frame rather than target_has_stack or coredumping.
1979 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1980 enums appropriately.
1982 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1984 * signame.c: Include defs.h and param.h.

2450 defines for the blocks of a blockvector that contain global and
2451 file-static symbols and the first of the smaller scope contours.
2452 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2453 decode_line_1, make_symbol_completion_list): Use the above.
2454 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2455 * dbxread.c (end_symtab): Ditto.
2456 * expread.y (block): Ditto.
2457 * mipsread.c (throughout): Ditto.
2458 * symmisc.c (free_named_symtabs): Ditto.
2460 * symtab.c (list_symbols): Process the first symbol of the
2461 static psymbols list.
2462 (types_info): Restore this function from its untimely #if 0.
2463 It's not perfect, but it is better than nothing.
2464 (_initialize_symtab): Restore "info types".
2466 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2468 * m68k-stub.c: Remote stub for 680x0's, created from
2469 rem-m68k.shar (which is removed).
2470 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2471 Remove RCS log stuff now that we use CVS and it blows our diffs.
2473 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2475 * symmisc.c (free_named_symtab): Make it work, in its current
2476 kludgy fashion. Change result to indicate if we blew away bkpts.
2477 * dbxread.c (end_symtab): Accumulate result from
2478 free_named_symtab and print warning if we blew user's state.
2479 * symfile.h: free_named_symtab now returns an int.
2481 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2483 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2484 is the first symbol read, even if not mainline.
2485 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2486 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2487 (set_section_command): New command ("section xxx yyy" -- should
2488 be renamed to "set section xxx yyy" FIXME) which sets the
2489 base address of a section of the exec file, overriding the
2490 virtual address that BFD reports.
2492 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2494 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2495 load symbols at any address while examining an exec file.
2497 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2499 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2500 for printing the float info is host-dependent, not
2501 target-dependent. FIXME.
2502 * i386-pinsn.c: Move #includes to top, remove useless ones.
2503 * i386-tdep.c: Don't bother including <.../reg.h> since we
2504 don't use it (and it doesn't exist on host systems).
2506 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2507 Convert negative numbers properly.
2508 (ieee_test): Make numbers really random; fix format arg.
2510 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2511 * core.c (core_detach): Unpush core_ops, which might not be on
2512 top. We used to just pop the top, which broke things. Don't
2513 need dont_repeat() any more.
2514 (core_file_command): Psst! Don't repeat it.
2515 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2516 * expprint.c (print_subexp): Avoid switch fallthru on
2517 BINOP_ASSIGN_MODIFY, so we can print += and such.
2518 * frame.h: Fix typo.
2519 * inflow.c (kill_command): After killing inferior, print our
2520 current frame in the core file, if we have one.
2521 (generic_mourn_inferior): When inferior dies, either select
2522 the current frame (in the new target, e.g. core file), or
2523 set both the current and selected frames to NULL.
2525 Changes from Peter Schauer.
2527 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2529 * Make all file names fit in 14 characters (sigh and damn!):
2530 mv hp300hpux-xdep.c hp300ux-xdep.c
2531 mv symmetry-xdep.c symm-xdep.c
2532 mv symmetry-tdep.c symm-tdep.c
2533 mv convex-opcode.h convx-opcode.h
2534 mv tm-vxworks960.h tm-vx960.h
2535 mv tm-vxworks68.h tm-vx68.h
2536 mv Makefile.srcdir Makefile.sdir
2537 mv gdb-int.texinfo gdbint.texinfo
2538 mv remote-sa.m68k.shar rem-m68k.shar
2539 mv remote-multi.shar rem-multi.shar
2540 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2541 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2542 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2545 * command.c (user_info_1, user_info): New command for listing
2546 the user-defined commands.
2548 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2550 * dbxread.c (really_free_pendings): Clear file_symbols
2551 and global_symbols after freeing them; otherwise, running
2552 this function twice (if it appears twice on the cleanup
2553 chain), we try to free things twice.
2555 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2556 based on text_addr (the address of text in core), not on addr (the
2557 offset between text in the .o file and in core). This change
2558 is from Peter Schauer.
2560 * main.c: Define ALL_CLEANUPS as a cast of zero.
2561 (return_to_top_level): Use it.
2562 (main): Do all cleanups after each command run as part
2563 of the gdb startup sequence. Also do all cleanups before
2564 entering the command loop, and every time we exit the command
2565 loop and reenter. Before, the cleanups from the startup sequence
2566 were being left undone until the first error!
2567 (command_loop): Rename do_nothing cleanup to command_loop_marker
2568 so we can see it easily when examining the cleanup chain.
2569 (init_signals): Add another do_nothing for signal handling.
2570 (quit_command): Only try to kill target if it has execution.
2571 Problems in the target stack got us into a state where
2572 inferior_pid was nonzero but none of the targets had execution.
2573 In this state you couldn't exit gdb.
2575 * dbxread.c: Two changes from Peter Schauer.
2576 (echo_command): Fflush output after an echo command.
2577 (show_history): Pass all args to cmd_show_list.
2579 * utils.c (init_malloc): Call mtrace to turn on tracing
2580 if the environment variable MALLOC_TRACE is set to a file name.
2581 * mtrace.c: Add source file which provides a log of every malloc,
2582 free, and realloc to a trace file.
2583 * mtrace.awk: Add source file which analyzes the trace file.
2584 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2585 (VERSION): Roll to 3.94.3.
2587 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2588 (check_duplicates): Don't bother with watchpoints.
2589 (set_raw_breakpoint): Comment about danger of this routine.
2590 (watch_command): Parse and eval all args before calling
2593 * solib.c (find_solib): Avoid error in referencing memory to
2594 see if any more shared libraries have been added. This is
2595 particularly useful if the target has terminated. Bug reported
2598 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2599 in bringing up 3.94.2 on the Sun-3.
2601 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2602 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2603 expression (in scope) before reenabling watchpoint.
2604 * signame.c (init_sigs): Add missing declaration of i, fix
2605 sys_siglist declaration.
2606 * source.c (list_command): Fixed range computation to use
2608 * stack.c (backtrace_command): Do not allow command if target has
2609 no stack, print informative error message.
2610 * target.c (target_command): Do not write into command line
2611 because this fails if the target command is used in a user defined
2612 command. [This change was enhanced by gnu to support any-
2613 unique-prefix matching on target names.]
2614 * valops.c (value_struct_elt): Avoid infinite loop on an
2615 erroneous attempt to print the member of function (try p main.p).
2617 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2619 * expread.y (name_no_typename): Avoid reduce/reduce errors
2620 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2621 Since the GDB parser really doesn't use name_no_typename in a
2622 name-only context, the parser can't tell the diff between
2623 names and numbers here. Avoid allowing a name_no_typename
2624 to be a NAME_OR_*INT to resolve the conflict.
2626 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2628 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2630 * valprint.c (val_print_fields): bitfield printing didn't handle
2631 byte order. Indirect through a few more fns to cope.
2633 * values.c (modify_field): also cope with byte order.
2635 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2637 Cleanup for release 3.94.2:
2639 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2640 include files. Roll version to 3.94.2.
2642 * coffread.c (init_stringtab): Read length into unsigned char
2643 array before swapping; don't assume 32-bit longs.
2645 * target.c (target_info): Don't bother with get_sym_file, just use
2646 the symfile global variable.
2647 * symtab.h, symfile.c (get_sym_file): Delete it.
2649 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2650 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2651 (read_type): Replace one more error() with complain().
2653 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2655 * i960-tdep.c: Fix copyright attribution.
2657 * config.gdb: Quote all backquotes in doublequotes. You can
2658 quote me on that. BSD 4.4 shell found this one.
2660 * infptrace.c (throughout): The third argument to ptrace is an
2663 * infrun.c (wait_for_inferior): When program has terminated, we
2664 have to call target_terminal_ours before we pop that target off
2665 the stack (e.g. before a call to target_kill or
2666 target_mourn_inferior). This fixes problem where a program
2667 terminates, then GDB stops for (tty output) and you have to type
2668 "fg" to the shell to resume it. FIXME: This code for what to
2669 do after termination really should be in normal_stop instead.
2671 * gdbcore.h (read_memory_check): Change declaration; it changed
2674 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2675 4.4 prereleases, this avoids a bug in their sgtty compatability
2677 * remote.c: Use terminal.h rather than hand-rolling the same.
2679 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2680 * utils.c (strsave, strstr): Fix arg types.
2681 * valprint.c (val_print): lint
2683 MIPS symbol table support from Per Bothner:
2685 * symfile.c (symtab_fns): Remove initializer table that needs to
2686 be hacked for each new symbol file format supported.
2687 (add_symtab_fns): New function, chains symbol table
2688 handlers into the global list.
2689 (symfile_init): Search this list.
2690 * symfile.h: Add next pointer, declare add_symtab_fns.
2691 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2692 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2694 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2695 symbol *). Thus, we no longer need the hack to trash
2696 pst->filename. Good, since that hack confused code in symfile.c!
2698 (reorder_symtabs, destroy_all_symtabs): Removed static
2699 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2700 Instead, the latter now uses a temporary array (stack-allocated
2701 from an obstack, and then freed).
2703 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2704 haven't been set in the outermost stBlock of a procedure. This was
2705 a problem with f77 binaries on Ultrix 4.?.
2707 (new_symtab, new_symbol, new_type): Continue changing code to use
2708 obstacks more and otherwise conform to dbxread internal style.
2709 Made the free_code of symtabs be free_linetable (as in dbxread)
2710 instead of free_contents. This implies memory leaks when reading
2711 a new symbol table, until the conversion is finished. Did change
2712 (struct symbol) and (struct type) to be allocated on the
2713 symbol_obstack. Blocks and blockvectors are among the things
2716 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2717 tested much, but it solved one problem (reported by Meissner), and
2718 cleans up some other things. The problem happened when an
2719 included file contains actual code (functions) and not just
2720 definitions. The mips coff is a little inconvenient there, since
2721 it may cause a procedure to be mapped to the wrong psymtab.
2723 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2724 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2725 this will need work for the new core paradigm.
2727 Opcode patches from the net:
2729 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2730 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2731 missing altogether - they are added here. From Bruce Bauman.
2732 * mips-opcode.h: The low mask for C0 instructions was too small.
2733 From Garrett Lau. I modified the fix to check the entire 32-bit
2736 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2739 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2741 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2743 * dbxread.c (read_type): Pointer subtraction (value_sub in
2744 valarith.c) sometimes failed because the types of the
2745 pointers being subtracted were not identical.
2746 These differed because dbxread.c was allocating pointer types
2747 using dbx_alloc_type+smash_to_pointer_type instead of
2748 lookup_pointer_type. I failed to find a justification for the
2749 former, so I changed it to use the latter. Similarly, I
2750 replaced smash_to_function_type by lookup_function_type,
2751 and smash_to_reference_type by lookup_reference_type.
2753 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2754 _initialize_mipsread): corresponding changes.
2756 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2758 * source.c (mod_path): Do tilde_expand on each component of the path,
2759 rather than on the (list of) paths as a whole.
2760 (print_source_lines): Set first_line_listed in addition to
2761 current_source_symtab and current_source_line. If the source was
2762 not findable, after a "dir" command to fix the problem,
2763 a "list" would get the wrong lines.
2765 While I was there... (gnu):
2767 * dbxread.c (read_type): Change error to complaint.
2769 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2771 First attempt at detailed understanding of symbol table memory alloc.
2773 * dbxread.c (dbx_symfile_read): Free our string table if we
2774 aren't the mainline. Free the "info" struct since we're done with
2776 (init_psymbol_list): Free any previously allocated psymbol lists.
2777 (): FIXME: Should realloc-down the psymbol lists when done reading
2778 the main symbol file?
2780 * symmisc.c (free_symtab): Free fullname field too.
2782 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2783 (REGISTER_ADDR): Make result type unsigned int.
2785 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2786 define REGEX must also define REGEX1 (its dependency).
2788 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2790 * tconfig/i960: No longer works, points you at vxworks960 or
2793 * xgdb.c, XGDB-README: Remove file. Users can get the much
2795 * Makefile.dist: Remove all trace of xgdb.
2797 * breakpoint.c (breakpoint_1): Pass demangle arg to
2798 print_address_symbolic.
2799 (clear_breakpoints): Remove unused function.
2800 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2801 (breakpoint_re_set): Use catch_errors to do them all anyway.
2803 * gdb-int.texinfo (Host versus Target): Add section on what is
2804 a "host" feature versus what is a "target" feature.
2806 * infcmd.c (path_command, path_info): Handle the PATH variable
2807 (object search path) as conveniently as the source search path.
2808 * environ.c (set_in_environ): Set some vars in GDB's environment,
2809 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2810 * source.c (mod_path): New function, from guts of
2811 directory_command, modifies a path. Used by path_command.
2812 (directory_command): Call it.
2813 * defs.h (strsave): Declare.
2815 * utils.c (sevenbit_strings): Add new printing option.
2816 (printchar): Use it.
2817 (strsave): Provide this handy helper routine.
2818 (set_width_command): Rename set_screen_width_command.
2819 (_initialize_utils): "set screen-width" => "set width";
2820 "set screen-height" => "set height"; add sevenbit-strings.
2822 * infcmd.c (do_registers_info): Print floating point registers
2823 in raw hex as well as float format, regardless of whether it is
2824 a "virtual" convertible register.
2825 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2826 regs as a double, just in case it's being used that way.
2827 * values.c (unpack_long): Comment on array/function coercion.
2828 (unpack_double): Argument is in target byte order now. For
2829 integer arguments, just call unpack_long and float the result.
2830 * m68k-tdep.c: include defs.h for "const" handling.
2831 * remote-nindy.c: Use ieee-float stuff.
2832 (nindy_fetch_registers): Unpack double regs to host double, then
2834 (nindy_store_registers): Pack extendeds to host double, flip
2835 around by misusing unpack_double, send as target double.
2837 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2838 zero, as when stopped at the first instruction of a process.
2840 * blockframe.c: Fix filename in comment (param.h => tm.h).
2841 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2842 * tm-68k.h: Fix typos.
2844 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2846 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2848 * coredep.c (fetch_core_registers): Pass end-address of register
2849 section to register_addr as expected. Don't call supply_register
2850 if we'd just pass it garbage.
2852 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2854 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2856 * target.c (push_target, target_info): Cast enums to int for < or
2859 * stack.c (print_frame_info): Identify source file & line
2860 even if we can't print it.
2862 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2864 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2866 Clean up IEEE floating point support.
2868 * ieee-float.h: New file.
2869 * ieee-float.c: Write real routines to convert between host
2870 doubles and various target IEEE extendeds.
2871 * m68k-xdep.c: Eliminate assembler code for extended floats.
2872 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2873 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2874 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2875 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2876 double_to_ieee_extended.
2877 * i960-tdep.c: Define ext_format_i960.
2878 * m68k-tdep.c: Define ext_format_68881.
2879 * sparc-tdep.c: Define ext_format_sparc, though unused.
2880 * Makefile.dist (HFILES): Add ieee-float.h.
2881 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2884 Obsolete the "coffstrip" program in favor of using BFD's strip.
2886 * nindy-share/coffstrip.c: Remove file.
2887 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2888 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2889 * tconfig/nindy960: Remove reference to coffstrip.o.
2891 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2893 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2895 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2896 * dbxread.c: Remove static symfile_bfd.
2897 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2899 * inftarg.c (child_detach): Pop the child_ops vector if the
2900 detach is successful.
2901 * remote-nindy.c (nindy_create_inferior): Don't push a new
2902 nindy_ops since nindy uses the same one for execution and memory
2904 * core.c (core_ops): Use child_attach and child_create_inferior
2905 rather than default attach and create_inferior functions.
2907 Handle floating point registers in core files.
2909 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2910 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2911 This version untested since BFD doesn't yet support sun3 core
2913 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2914 conventions. Fix comments and style. This version has not
2915 been compiled yet, since we have no HP inhouse.
2916 * core.c (get_core_registers): Look for two sections, ".reg"
2917 and ".reg2", and pass both to fetch_core_registers sequentially.
2919 Revise directory path yet again.
2921 * source.c (forget_cached_source_info): Not static any more.
2922 (init_source_path): New default source path is "$cdir:$cwd".
2923 (dir_command): Handle variable arguments ($cdir, $cwd).
2924 (source_info): Print "Compilation directory" rather than
2925 "Originally compiled in" to remind people of $cdir.
2926 (openp): If the path contains $cwd, use current directory.
2927 (open_source_file): If compilation directory is known, replace
2928 first $cdir in path with the compilation directory.
2929 (print_source_lines): Even if we can't print the lines, set the
2930 current symtab and line for future commands like "info source" or
2931 "breakpoint". Also, error message now contains the file name,
2932 line number, and file access error message.
2933 (_initialize_source): Fix help text to describe changes.
2934 * main.c (cd_command): Forget cached source info when we chdir.
2935 * utils.c (strstr): Add simple implementation.
2937 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2939 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2940 Byte-swap COFF symbol tables if necessary when reading them in.
2941 Use complain() to replace error message in one spot. Needs
2942 corresponding change in bfd/coff-code.h to make some symbol
2943 swapping routines non-static.
2945 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2947 Merge changes from Eirik Fuller, for UTek.
2949 * defs.h (errno): Add declaration.
2950 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2951 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2952 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2953 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2954 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2955 declarations of errno.
2957 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2959 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2960 <rpc/rpc.h> and <rpc/types.h>.
2962 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2964 * i960-tdep.c (examine_prologue): Add new argument limit,
2965 which stops the scan at the end of the prologue, or at the PC.
2966 This fixes a problem where it walks down into the code for the
2967 user's statements if that code looks like function prologues.
2968 Mark Fox and I have been bouncing this code back and forth, making
2969 small changes to it. Callers changed to match.
2971 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2973 Cleanup for gdb-3.94 release final:
2975 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2976 the .c files from vx-share and nindy-share, from the various
2977 macros, since they are not found via ALLDEPFILES.
2978 (SFILES): Add tm-i960.h.
2979 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2980 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2982 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2983 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2985 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2987 * am29k-tdep.c: Add contribution line.
2988 (examine_prologue): Cache information about function prologues in
2989 the misc-function-vector to avoid lots of references over the
2990 serial line while examining instructions.
2992 * core.c (core_close): New function made from cleanup_core.
2994 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2995 remote-vx.c, remote.c, target.c, target.h,
2996 Update target_ops vector to add attach, close, and load entries.
2997 Use add_syms_addr_command, not add_file_addr_command, for
2998 add_file. Break out close routine from existing code.
3000 * dbxread.c (really_free_pendings): Don't free pending_blocks;
3001 they are in an obstack.
3002 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
3004 (define_symbol): Add symbol type parameter; change callers;
3005 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
3006 it to influence the symbol class on the i960.
3007 (define_symbol): Swap LOC_CONST's into target byte order.
3009 * exec.c (exec_close): New function.
3010 (exec_file_command): Call it.
3012 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
3013 Fix byte order of frame pointer.
3014 (read_var_value): Result of 0 if var's value can't be found,
3015 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
3016 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
3017 (locate_var_value): Use read_var_value and use its lazy address
3018 as the location of the var's value. Lint.
3020 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
3023 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
3024 obsolete Intel versions in favor of vxgdb versions.
3025 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
3026 code dealing with byte order of values, which Intel did in host byte
3027 order rather than gdb-4's target byte order.
3028 (i960_frame_chain_valid): Move to nindy-tdep.c.
3029 (examine_prologue, skip_prologue, frame_find_saved_regs,
3030 frame_args_address, leafproc_return, saved_pc_after_call,
3031 pop_frame): Add vxgdb versions from Mark Fox.
3032 (examine_prologue, frame_struct_result_address): Add code
3033 to deal with the saved value of G13 (struct return address
3035 (frame_args_address): Modify Mark's version to prefer the
3036 saved value over the current value in the topmost frame.
3037 Cache result in the frame info to avoid performance hair in
3039 (print_fault): Add gdb960 code for printing faults.
3040 (_initialize_i960): Actually call check_host.
3042 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3043 add stub routines. FIXME, these currently just return zero!
3045 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3046 (attach_command): Call target_attach, not target_open, now.
3048 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3049 (child_attach): Rename from child_open.
3050 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3051 don't confuse it with a zero step_resume_break_address.
3053 * inftarg.c (child_detach): Eliminate inferior_pid test.
3054 (child_files_info): Clean up message a bit.
3055 (child_ops): Use child_attach, not child_open, to attach.
3057 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3058 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3059 findvar.c to here, since it depends on the contents of the
3060 shadow_contents of breakpoints, but keep if #if 0 since it is
3063 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3066 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3067 (ptype_command, display_command): Eliminate have_inferior_p and
3068 have_core_file_p in favor of target_has_stack or
3069 target_has_execution.
3070 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3071 code for actually finding the values of arguments, though we still
3072 keep track of the maximum stack offset for use in printing unnamed
3073 arguments. Handle missing FRAME_ARGS_ADDRESS.
3075 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3076 (struct nindy_regs): Define registers passed to/from nindy.
3077 (nindy_fetch_registers, nindy_store-registers): Translate between
3078 nindy and GDB formats for the registers.
3079 (dcache_init): Statically allocate the cache, since it was being
3080 allocated by a malloc that was never freed anyway.
3081 (nindy_create_inferior): Error, not core dump, if no exec file.
3082 (nindy_before_main_loop): Use target_load, not target_add_file.
3084 * remote-vx.c (net_load): Specify large timeout for load
3085 requests. Allow user to break out with INTERRUPT.
3086 (net_break): Remove useless code, clean up. Change callers.
3087 (parse-args, skip_white_space, find_white_space): Clean up arg
3088 parsing to cope with quoted strings.
3089 (net_wait, net_quit): Never call error, just return status.
3090 (vx_read_register, vx_write_register): Cleanup status checking.
3091 #ifdef the code based on which CPU we are using (960 or 68k),
3092 FIXME, this should be completely general but it isn't yet.
3093 (vx_xfer_memory, vx_resume): Cleanup status checking.
3094 (vx_run_files_info): Improve message.
3095 (vx_load_command): Renamed from vx_add_file_command. Allow load
3097 (net_ptrace): Remove unused routine.
3098 (vx_wait): Adopt code from vxgdb960 to cope with broken
3099 connections to target machine and prompt to disconnect. Remove
3100 debug printouts. Map some EVENT_'s to SIGnals.
3101 (add_symbol_stub, vx_open): Print names of object files we found,
3102 and "ok" if we read their symbols OK. Clarify output in general.
3103 (vx_attach, vx_detach, vx_kill): Add these commands.
3104 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3105 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3106 "info files" output, and create_inferior, since we already have
3109 * stack.c (frame_info): Replace Frame_unknown with 0.
3110 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3111 (return_command): Pop until the PC matches as well as the FP,
3112 so it works even if the FP is shared with another function,
3113 as in "frameless" or "leaf" procedures.
3115 * symfile.c (load_command): renamed from add_file_target_command.
3116 (add_syms_addr_command): renamed from add_file_addr_command.
3117 (add_syms_command): Stub to call target_add_syms.
3118 (_initialize_symfile): Change command names and descriptions,
3119 add-file => add-syms, and load from alias to its own command.
3121 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3122 maybe_kill_then_create_inferior): Default for attempts to start
3123 a process, if one is already running, is to ask about killing
3124 it and retry if yes.
3125 (upstack_create_inferior): #if-0 it, strata obsolete it.
3126 (push_target, unpush_target, pop_target): to_close() a target
3127 before unstacking it.
3128 (target_info): Renamed from target_files_info.
3129 (_initialize_targets): Rename "i files" as "i target", accessible
3132 * target.h: Improve comments about the target_ vectored routines.
3134 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3135 Convert commenting style to standard GNU style.
3136 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3137 (SKIP_PROLOGUE): No longer a no-op.
3138 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3139 (*_REGNUM): Sort register numbers.
3140 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3141 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3142 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3143 are now 10 byte extendeds, not 8 byte doubles.
3144 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3145 for nindy versus vxworks targets. FIXME, this should possibly go
3146 in the target vector.
3147 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3148 frame_saved_regs and arg pointer with each frame.
3149 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3150 (FRAME_ARGS_ADDRESS): Use cached result.
3151 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3152 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3153 (PRINT_RAMDON_SIGNAL): Call print_fault.
3154 (POP_FRAME): Now works.
3156 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3157 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3158 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3159 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3162 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3163 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3165 * valarith.c (value_subscripted_rvalue): Avoid handling
3166 floats and doubles specially; it gave alignment errors. Lint.
3168 * valops.c (value_of_variable, value_of_this): Error if unknown
3171 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3172 to avoid alignment problems.
3173 (value_print): Handle unknown value address.
3174 (cplus_val_print): Two args are ignored; remove them. Change caller.
3175 (val_print): Use unpack_long rather than pointer-deref.
3178 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3179 to avoid alignment problems.
3180 (value_being_returned): Error if return value unknown.
3181 (set_return_value): Add bogosity warning, FIXME. *
3183 * TODO: A woman's work is never done.
3185 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3186 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3187 Add ieee-float.o to OBS.
3188 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3189 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3190 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3192 Changes to generalize the VxWorks RPC protocol slightly, to handle
3193 i960 as well as 68000.
3195 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3196 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3197 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3198 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3199 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3200 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3201 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3202 so they will move in target byte order rather than network
3203 byte order (happens to be the same).
3205 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3207 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3209 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3212 Add contribution lines to various files, showing where they
3215 * breakpoint.c (break_insn, check_break_insn_size,
3216 read_memory_nobpt): Remove to mem-break.c.
3218 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3221 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3222 entry has bad register number. This change is not
3223 tested in this release, FIXME.
3225 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3228 * value.h: Force value's contents field to be aligned to hold
3229 at least a double or a long long (if supported). This avoids
3230 doing bcopy's in and out of the contents field.
3232 (step_1): Avoid coredump under obscure circumstances when we
3235 * symtab.h (misc_info): Add field to misc function vector for
3236 any kind of cached information the target code desires. AMD
3237 29000 uses this to avoid repeating examine_function_prologue's.
3239 * coffread.c: Lint. Remove static symfile, read_section_header.
3240 core.c (have_core_file_p): Lint: remove.
3241 expprint.c (print_subexp): Lint.
3242 infptrace.c, valops.c, valprint.c: lint.
3244 Roll in changes from vxgdb-5.0.1:
3246 * symtab.h: Comment byte order of each address class. Add
3247 LOC_LOCAL_ARG for frame-relative args (960).
3248 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3249 symtab.c, symmisc.c: ditto.
3251 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3253 * remote.c (remote_resume): Error if resume with a signal.
3255 * symfile.c (prim_record_misc_function): Clear misc_info.
3256 (fill_in_vptr_fieldno): Check stub type of arg.
3258 * valops.c (value_cast): Avoid looking up names of types whose
3259 name we don't know, to prevent coredump. Sun CC produces typedef
3260 rtx and the name of *rtx is zero...
3262 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3264 Roll in changes from final AMD 29000 port (Tiemann).
3266 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3267 for ../include/a.out.encap.h. This might not work now that BFD
3268 is separately compiled. Instead, BFD support for encap will have
3269 to translate machine type 29k into the right COFF_MAGIC.
3271 * infcmd.c: Remove references to inferior_pid that aren't used
3272 in actual ptrace calls; use target_has_execution, etc.
3273 (have_inferior_p): Remove function.
3274 (program_info): Print target info rather than "process number";
3275 avoid gratuitous messages unless from_tty.
3276 (run_stack_dummy, finish_command): Set proceed_to_finish.
3277 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3278 main.c: Lint. Lose have_inferior_p().
3279 inferior.h (have_inferior_p): Remove, lint.
3280 (proceed_to_finish): Add flag to ask that all regs be saved
3281 by normal_stop, for the few commands that need it, speeding up
3282 serial I/O. Add comments to stop_registers.
3284 * remote-eb.c: Remove newline from breakpoint message we grep
3285 for. Never time out when running the user program.
3289 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3291 Roll in changes from vxgdb-5.0.1:
3293 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3294 symbol in its raw form, we are processing an unlinked ".o" file.
3295 See if the target environment has assigned it an address, using
3296 target_lookup_symbol (VxWorks does), and enter it into the symtab
3299 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3300 68k versions for a simpler version that assumes zero FP at bottom.
3301 Fixes bug of truncated stack reports.
3303 * target.h (target_lookup_symbol): Define this routine's args
3304 and result, finally.
3306 * target.c (nosymbol): Default routine for target_lookup_symbol.
3307 (target_default): Default lookup_symbol and call_function too.
3308 (files_info): Only print has_all_memory warning if a non-dummy
3311 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3312 vx_convert_from_virtual): If target does not have floating point,
3313 zero register "values", and avoid doing cross-net conversions.
3314 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3315 (vx_open): Rearrange code that attaches to target and reads
3316 symbols for all loaded modules, to work if some of the modules
3317 are not accessible. Add symbol_stub() and add_symbol_stub()
3318 as callbacks from catch_errors(). Allow connect attempt to be
3319 interrupted painlessly with ^C (FIXME, there are still some bugs
3320 if the interrupt happens during symbol reading.). Print
3321 final message with puts_filtered, since symbol messages are
3326 * main.c (catch_errors): Only print errstring if non-null.
3327 (command_loop): Avoid an ioctl per command to test ISATTY.
3329 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3330 (vx_xfer_memory): Return correct result!
3331 (vx_files_info): Indicate whether target has float or not.
3332 (vx_lookup_symbol): Complain, not error, if target gone.
3333 (vx_open): Print "Connected" msg before disabling immediate-quit.
3334 [FIXME: lookup_symbol and vx_open changes need testing.]
3336 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3337 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3338 contributor lines and update copyrights to 1991.
3340 Changes from an attempted H-PUX host port:
3342 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3343 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3344 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3345 * remote-vx.c: include <sys/time.h> for HPUX.
3346 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3347 "core_file_command" routine to BFD regime. May not work yet.
3349 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3351 * xgdb.c: Replace X10 version with some VJ version.
3352 (FIXME: Its copyright assignment is not on record.)
3353 * xgdb.c: Update include files to X11R4 (Xaw crud).
3354 (xgdb_display_source, create_text_widget): fix call to
3355 get_filename_and_charpos. Rewack source window stuff for X11R4
3356 (gleaned from include files, and "nm's" of binary libraries, since
3357 I had no doc available).
3358 (append_selection, append_selection_word): Disable with FIXME
3359 since R4 changed interface here.
3360 (create_buttons): Add back the old set of buttons.
3361 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3363 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3364 Roll VERSION to 3.94 (not yet final though).
3366 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3368 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3369 obstack_int_grow, obstack_int_grow_fast): Eliminate
3370 cast on left of assignment, which gives MIPS cc fits and is
3373 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3374 F_ALIAS. Use printf, not fprintf, when not passing a file
3376 (compare_opcodes): Check that identical instructions have
3377 identical opcodes, complain otherwise.
3379 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3380 was reported by Roland McGrath.
3381 (unimp): Only match if exactly zero instruction. (Roland)
3382 (branches and traps): Generate all variations of these
3383 instructions with macros, based on a single call that defines
3384 each condition name and its binary representation.
3385 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3387 * valprint.c (val_print_fields): Take, and use, format parameter.
3388 This means that "p/x struct" again prints the elements in the
3389 desired format. Changed callers.
3391 * stack.c (frame_info): Use filtered output, and indicate wrap
3392 points. Remove kludgy formatting designed to avoid line wrap.
3394 * utils.c (wrap_here): If the line is already full (because
3395 we had printed a long indent or long wrapped string), do an
3396 immediate newline-and-indent.
3398 * m68k-pinsn.c (print_insn_arg): Bugfix from
3399 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3400 instruction is incorrectly disassembled as bkpt #8.
3402 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3403 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3404 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3405 and then will dump core (sometimes). I traced it back to an
3406 uninitialized symfile_name in psymtab_to_symtab.
3407 (const_vol_complaint): Add quotes to message.
3408 (define_symbol): Only believe line number if gcc_compiled.
3409 Avoid allocating symbol if we will not return it.
3411 Add target strata support so that newly established targets go
3412 into their right place in the target stack (e.g. a new exec file
3413 doesn't wipe out the ability to access the running process).
3415 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3416 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3417 and initialize it properly in all the targets.
3419 * target.h: Document strata. Change return type of push_target.
3421 * target.c (nomemory): new function for dummy memory access.
3422 (tcomplain): Rename complain, now also used in symfile.c.
3423 (push_target): Push targets within strata. New return value shows
3424 whether new target is on top of stack or not. Always keep dummy
3426 (target_files_info): Ignore dummy target.
3428 * core.c (core_open): Warn user, and skip accessing file, if the
3429 core target is not the topmost target in the stack.
3430 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3433 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3434 target_ops, it doesn't belong there since we have no regs there.
3435 Change name of target from machine => memory to clarify.
3437 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3439 * Freeze version 3.93 for release.
3441 * Makefile.dist: Handle vx-share and nindy-share subdirs
3442 properly when building gdb.tar.Z.
3444 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3445 printed in various places, so I could change just one copy.
3447 * dbxread.c, coffread.c: Change references to bfd->iostream
3448 to cast to FILE *, now that BFD avoids needing types defined
3449 in other header files.
3451 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3453 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3454 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3455 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3456 (actually gcc -Wall).
3458 * dbxread.c: Remove first_global_sym, last_global_sym, since
3459 they are never referenced.
3461 * defs.h (baud_rate): Declare.
3462 main.c: Define it, and add the -b option to set it.
3464 * gdb-int.texinfo: Add text on how to define a new host or target
3465 architecture, prompted by Per Bothner's questions about MIPS
3468 * gdb.texinfo: Document "complaints". Change doc of -q since
3469 gdb no longer prints the copyright and blurb if you specify a file
3470 name to be debugged (just like Emacs). Add doc for Nindy-specific
3471 command line flags for specifying target serial port and such.
3472 Update copyright to 1991.
3474 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3475 has taken over for us the job of ripping up executable files. The
3476 crud caused Per Bothner's port to not compile.
3478 * infrun.c (normal_stop): Avoid printing "Program exited
3479 normally" if we are in batch mode. This allows a GDB which
3480 executes a program on a target system, to behave like a Unix
3481 command (input from stdin, output to stdout, no extraneous
3484 * main.c (main): Allow additional machine-dependent command line
3485 options to be specified with the ADDITIONAL_OPTIONS,
3486 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3487 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3488 processing to occur just before the main loop with
3489 BEFORE_MAIN_LOOP_HOOK.
3490 (main): If a "core file" argument is specified, and it is not a
3491 core file, try it as a process ID to attach.
3492 (symbol_completion_function): Attempt to cope with
3493 "show screen-" TAB, not very successfully. This needs more work,
3495 (batch_file): New function, returns whether we are reading
3496 commands from an interactive tty on stdin, or from somewhere else.
3497 Called by normal_stop since it doesn't get from_tty passed down
3498 to it like many commands do.
3500 * remote-nindy.c: Handle command line options for nindy
3502 (nindy_before_main_loop): Prompt user for tty name if they
3503 don't specify it before getting to the interactive command loop.
3505 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3506 and -r command line options. Also add hook before main loop
3507 to make it easy to specify a tty.
3509 * TODO: More things to do, one done.
3511 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3513 * dbxread.c: Make complaint() calls pass pointer, not struct.
3514 Add complaints about badly formatted C++ type information
3515 (const/volatile indicator, and parse errors resulting in
3516 error_type). Fix C++ virtual member fn comment.
3517 (read_struct_type): Avoid bumping pointer if we got a parse
3518 error; this prevents our walking beyond the end of a string.
3519 Terminate loop on null char as well as semicolon.
3520 (process_one_symbol): Fix the LBRAC fix so that it uses the
3521 last previous SLINE, FUN, or SO record's PC address. C++ debug
3522 symbols did not have SLINE records in a useful order compared
3523 to the LBRAC records.
3524 (define_symbol): Handle "catch" records.
3526 * symtab.c (check_stub_type): Added new complain
3527 `stub_noname_complain' and added a consistency check to
3528 keep the debugger from crashing when finishing from an
3529 exception frame. A real fix will be needed later.
3531 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3533 * infcmd.c (attach_command): Make global.
3535 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3536 but make them easy to comment out. Perhaps later they should
3537 be enabled by what CPU you configure for? FIXME.
3538 (VERSION): Roll to 3.93.
3539 (pinsn.o): Remove rule for obsolete file.
3540 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3542 Run down a problem that manifested by printing the wrong function
3543 name in stack traces of read_ofile_symtab. Turned out that the
3544 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3545 the LBRAC symbol with an address in the *data* segment, which
3546 blew our binary search through the blocks.
3548 * dbxread.c: Use the complain() facility consistently to bitch
3549 about problems in the symbol file we are reading.
3550 (finish_block): Add code to check the nesting of the blocks;
3551 complain and Procrust them to fit if wrong.
3552 (make_blockvector): Check the order of the blocks, complain
3553 [but don't cope] if wrong.
3554 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3555 symbols to be sure their PC value is greater than the last SLINE
3556 (line number) symbol we've seen, complaining and adopting the
3557 SLINE PC value if wrong.
3559 * symfile.h (struct complaint, complaint_root, complain,
3560 clear_complaints): Add.
3561 * symfile.c (complain, complaint_root, clear_complaints): Add
3562 facility to deal with non-fatal complaints and to regularize their
3564 (symbol_file_add): Clear complaint counters to allow new complaints.
3565 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3567 * dbxread.c (dbx_symfile_read): Remember the address and size
3568 of the string table for the main symbol file, so we won't read it
3570 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3571 to avoid reading the string table yet again. Lint.
3572 (throughout): Improve filtered output, including word wrap.
3573 (read_range_type): Improve Bothner's fix to handle other types too.
3575 * utils.c: Improve line wrap implementation. Handle unlimited
3576 width by making chars_per_line unsigned.
3577 (puts_filtered): New, easy, function.
3579 * defs.h (puts_filtered): add.
3581 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3582 call the identical sort_symtab_syms() in symfile.c instead.
3584 * expread.y: Suggest the `file' command rather than `symbol-file'.
3586 * command.h (enum var_types): Add zinteger for seroable
3588 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3589 nested if's into a switch.
3591 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3592 we did not stop because of a breakpoint (it must have been for
3593 some other reason, like a "stepi"), so don't print anything.
3595 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3596 doesn't include <sys/types.h>, old SunOS's require it for
3599 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3601 A test port of gdb-3.92.6 to the Sony NEWS.
3604 Don't normally link in remote- or vx stuff.
3605 Some of it doesn't compile, and it wastes space for 99% of the users.
3606 Remove reference to no-longer-used HAVE_VPRINTF.
3607 Fixed BFD_DEP typo to BFD_DIR.
3609 Fix cast in arg to bfd_h_getlong.
3610 Make char *prefix be const.
3611 Fix how certain range types are mapped into builtin unsigned int types.
3613 Remove 2 #includes. They cause errors (on Sony, at least),
3614 and aren't needed (they wern't in earlier versions).
3616 print_address_symbolic should never demangle labels
3617 (since it prints *assembler-level* labels).
3619 [This was superseded by the change to printcmd below.]
3622 Add some "volatile" return types to avoid warnings.
3623 If MISSING_VPRINTF add vprintf function and not just macro
3624 (since vprintf is used in printcmd.c).
3626 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3627 (The latter isn't grokked by some PCC-based compilers.)
3629 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3631 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3632 * nindy-share/coffstrip.c
3633 Added some forward declarations (otherwise, gcc complains
3634 about implicit extern redefined as static).
3636 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3638 Changes inspired by Per Bothner:
3639 * printcmd.c (print_address_symbolic): Take additional parameter
3640 specifying whether to demangle.
3641 (print_address): Pass in asm_demangle to control demangling.
3642 (print_address_demangle): New fn, takes explicit arg to control
3644 * utils.c: Add new vars demangle and asm_demangle, and let them
3646 (fputs_demangled): If !demangle, just print the argument.
3647 (fprint_symbol): If !demangle, just print raw symbol.
3648 * valprint.c (val_print): Call print_address_demangle rather than
3649 print_address, to cause demangling to depend on the global
3650 rather than assembler-level demangling setting.
3651 * WHATS.NEW, gdb.texinfo: Document.
3653 * main.c (show_command): Show all settings if no arg.
3654 (initialize_main): Make "info set" the same as naked "show".
3655 * command.c (cmd_show_list): Handle prefix commands in the
3656 list, and print the name of the setting as well as its English
3657 description and value.
3659 Allow gdb functions to specify where a line should wrap if it
3660 exceeds the size of a terminal line. Use it to make the output
3662 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3663 of the right size when screen width changes.
3664 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3665 (wrap_here): New fn, indicates a point in the output where we
3666 should wrap the line rather than just letting it overflow at a
3668 (fputs_filtered): Implement wrapping.
3669 (n_spaces): New fn, returns a pointer to N spaces.
3670 (print_spaces_filtered): Use n_spaces.
3671 * defs.h (n_spaces): Declare.
3672 * stack.c (print_frame_info): Wrap with 4-space indent after
3673 fn name and before filename and line number.
3674 * printcmd.c (print_frame_args): Wrap with 4-space indent
3675 before each argument name is printed.
3676 * valprint.c (value_print): Wrap with no indentation before
3678 (val_print_fields): Wrap with indentation relative to nesting
3679 level before each field name.
3680 (val_print): Wrap with nesting indentation before array elements.
3681 * command.c (do_setshow_command): Avoid extra newlines,
3682 wrap with 4-space indent around values printed, end with period.
3683 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3685 * breakpoint.c (breakpoint_1): Implement addressprint for
3686 "info breakpoints" display. Change file name and line number
3687 format to " at file:nnn" rather than " (file line nnn)".
3688 * gdb.texinfo: Document.
3691 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3693 Frozen for gdb-3.92.6 release.
3695 README, WHATS.NEW: Update for 3.92.6 release.
3697 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3698 coffread.o from configs since it is now built by default.
3699 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3700 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3701 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3702 from configs since it is now built by default.
3704 Makefile.dist: Update for release 3.92.6. Handle files that
3705 have been moved to ../include, ../getopt, or ../bfd. Add
3706 saber.suppress and tests directory. Add config.status to
3707 the release (it will say "none").
3709 coredep.c: Minor formatting fixes.
3711 These changes were made in early December but only checked in now:
3712 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3713 nindy-share/nindy.c: lint
3714 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3715 register values coming back from the target; we store values
3716 in target byte order everywhere.
3718 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3720 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3722 * valprint.c (cplus_val_print, val_print_fields): New functions,
3723 which print C++ objects. They conspire to avoid printing a
3724 virtual base class more than once, following all the twists and
3725 turns of C++ virtual base rules.
3726 (val_print): Call the above rather than do it by hand.
3728 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3729 symbol file, not for added files like shared libs. This really
3730 needs to be generalized to a timestamp per file.
3732 * core.c (cleanup_core): Avoid coredump if no core file.
3734 * config.gdb: Accept -host or -target in place of +host or
3737 * coffread.c (find_linenos): Avoid desupported BFD interface
3738 to line numbers. We still read them manually rather than using
3739 BFD's "generic" features.
3741 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3743 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3745 * Makefile.dist: Eliminate use of $< in explicit targets.
3747 * readline/Makefile: Use $< rather than $*.c, which does not
3748 include the VPATH in GNU Make.
3750 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3751 copies of tconfig/i960, added for global configuration
3752 compatability. All i960 versions can read both coff and b.out.
3754 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3755 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3758 * TODO: Think of more things to do.
3760 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3762 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3763 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3764 64-bit float conversion.
3766 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3767 equivalent to sun?os4 so global config works.
3769 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3771 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3773 * main.c: Only declare linesize once; declare pagesize not at
3774 all, since it is never used.
3775 (main): Clear newly allocated line before it is used.
3777 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3779 Further stabilization for the Intel 960.
3781 * Makefile.dist: Parameterize the location of the "include"
3782 and "bfd" directories, as well as "getopt". Add symfile.c.
3783 Link in both dbxread and coffread. Fix up "make depend" to
3784 rewack the locations of include, bfd, and getopt in its output.
3786 * README: Document moving include files, improve some of
3789 * coffread.c: Move common code out to symfile.c. Change
3790 symbol_file_command style interface to use new *_symfile_init
3791 and *_symfile_read interface under BFD. Use BFD internal
3792 info to locate line table, symbols, etc.
3794 * core.c (core_fetch_registers): Rename to get_core_registers
3795 to avoid confusion with fetch_core_registers.
3796 (register_addr): Move to coredep.c, which is already machine
3797 dependent. This leaves core.c pretty clean of dependencies.
3799 * coredep.c (register_addr): Accept this routine from core.c.
3801 * dbxread.c: Move common code (with coffread.c, etc) into new
3802 symfile.c. Each psymtab now contains a pointer to the
3803 format-dependent function that knows how to read it in. Make
3805 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3806 (process_one_symbol): Add code to complain about a "compiler bug
3807 we muzzle here", if we actually see it.
3809 * eval.c (evaluate_subexp): Insert missing "break" statements
3810 in code that determines whether a variable is an lvalue in
3811 memory, register, or whatever. I detected this via a compiler
3812 bug in which it *almost* mashed out the whole switch statement.
3814 * gdb-int.texinfo: Add minor sections on configuring gdb for
3815 release, and about the README file.
3817 * infcmd.c (registers_info): Fix formatting somewhat. Still
3818 not as pretty as before, but it handles byte swapping.
3820 * remote-nindy.c: If data cache routines are interrupted while
3821 waiting for the remote end, be sure that any uninitialized cache
3822 blocks are on the free list, not on the valid list!
3824 * symfile.h: Flesh out this header file with all the various
3825 routines and variables that have been merged in from dbxread.c
3826 coffread.c, and symtab.c to symfile.c.
3828 * symfile.c: New file, containing code common to dbxread.c,
3829 coffread.c, and some code from symtab.c. All generic code for
3830 reading symbol files should be in here now.
3831 (unrecord_misc_function): Remove unused function.
3833 * symtab.h: Remove file-reading things to symfile.h.
3835 * symtab.c: Remove file-reading things to symfile.c.
3837 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3838 to decode i960 fault types.
3840 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3841 target.c: Change type of the "resume" function from int to void,
3842 since its result was never used.
3844 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3846 * main.c: Replace "stupid" with "caution"; you now "set caution
3849 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3851 * infcmd.c (do_registers_info): Call val_print to deal with the
3852 byte order of the registers being printed. FIXME, this makes
3853 the formatting of the output uglier.
3855 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3856 defined, call it for signals the debugger doesn't itself use.
3857 The i960 uses this for more detailed fault information.
3859 * remote.c (remote_open): If arg is null, print help rather than
3862 * sparc-xdep.c (register_valid): Avoid declaring size, since
3863 various modules will think of various sizes depending on the
3864 architecture of their tm-file. FIXME, we need protection against
3865 actually entering one of those modules, which would clobber
3866 storage if not for the target architecture compiled into gdb.
3868 * stack.c (up_command, down_command): Always print the frame
3870 (up_silently_command, down_silently_command): New commands
3873 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3875 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3876 more parameters than it used to.
3878 * findvar.c (registers): Increase slop to 256 bytes, which should
3879 protect us against even most RISC machines with large register
3881 (locate_var_value): Move declaration inside related ifdef.
3883 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3884 throughout, to avoid throwing away buffered input from the board.
3885 (nindy_wait): Supply_register takes addr_of_value, not value.
3886 (i960_print_fault): Renamed from i80960_fault.
3887 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3888 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3890 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3891 we can set the PC in the call to proceed(). Unpush nindy_ops
3892 before pushing it on top, to avoid message to user. Eliminate
3893 commentary from Unix machines that just misleads here.
3894 (reset_command): Fix error message to suggest target command.
3896 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3898 Release 3.92.5 as frozen.
3900 Stabilize the merged release...with help from lint, Saber C,
3903 Everywhere: Add include files needed to declare return types
3904 of functions called.
3906 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3908 * breakpoint.h: Add undeclared breakpoint functions, and some
3909 functions for display handling since I couldn't think of a better
3912 * breakpoint.c (insert_breakpoints): Make code for disabling
3913 shared library bkpts more likely to work. It's used when we
3914 rerun a program and stop before the shared library has been
3916 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3917 cast from pointer, so it squeezes through catch_errors.
3918 (bpstat_stop_status): Fix logic broken some time ago. We now
3919 always create a bpstat if the stop address matches a breakpoint,
3920 even if we don't stop there -- just like the old code used to do
3921 before I got my fingers into it (sigh).
3922 (breakpoint_1): Print "ignore count" after "stop only if"
3923 condition, since that's how it actually works.
3924 (mention): Handle watchpoints as well as breakpoints.
3925 (watch_command): use set_raw_breakpoint and mention to do most
3926 of the work (and initialize all the fields!). Only pass one
3927 arg to parse_c_expression, since that's all it takes.
3929 * command.c (not_just_help_class_command): Rename arg to args
3930 since we ignore "unused argument" warnings on vars named "args".
3931 inflow.c (child_terminal_info): ditto.
3932 infptrace.c (kill_inferior): ditto
3933 main.c (catch_errors, version_info, quit_command, pwd_command,
3934 source_command, dump_me_command, editing_info,
3935 set_history_size_command, set_history, show_history,
3937 stack.c (locals_info): ditto
3938 target.c (target_files_info): ditto
3939 valprint.c (set_input_radix, set_output_radix): ditto
3941 * core.c: Remove old variables for handling core and exec file
3942 sections (data_start, data_end, stack_start, stack_end,
3943 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3944 text_end, exec_data_start, exec_data_end, text_offset,
3945 exec_data_offset, data_offset, stack_offset). They're
3946 superseded the more general build_section_table and
3948 (get_exec_file): Mention the `file' command.
3949 (read_memory_check): Rename to memory_error, and only call it
3950 in the case of an actual error.
3951 (read_memory, write_memory): call memory_error.
3952 (core_fetch_registers): Register section name is ".reg".
3954 coredep.c: Remove a bunch of crud now that all this file does
3955 is pull the registers out of a core file.
3956 (fetch_core_registers): Rewrite to actually work, I hope.
3958 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3959 Replace index() with strchr(). Remove all the pre-BFD macro
3960 definitions for accessing the symbol file.
3961 (struct dbx_symfile_info): Encapsulate the information that
3962 dbx_symfile_init needs to pass to dbx_symfile_read in this
3965 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3966 dbx_symfile_discard): Rearrange symbol file reading to divide
3967 the format-specific part from the format-independent part,
3968 leaving the format-independent part such as file name expansion
3969 and opening in symtab.c. This replaces
3970 partial_symbol_file_open and partial_symbol_file_read.
3971 Symbol_file_read, add_file, add_file_target_command,
3972 add_file_addr_command move to symtab.c. Pass an explicit
3973 "mainline" flag for when reading the main symbol table, rather
3974 than relying on the offset address to be zero or nonzero.
3976 (dbx_symfile_read): Don't allow void *'s to be printed as
3978 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3979 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3980 macro" debug version really work.
3981 (read_dbx_symtab): Remove unref'd parameter inclink.
3982 Avoid swapping N_SLINE symbols, for speed.
3983 Merge N_TEXT!N_EXT case with the other external symbol
3984 definitions' case. Add comments.
3985 (start_psymtab): Allocate the symfile name in the psymtab on
3986 the psymbol_obstack, rather than using the caller's storage.
3987 (end_psymtab): Only allocate a dependencies list if there are
3989 (psymtab_to_symtab_2): Use BFD when reopening file to read
3990 its symbols for real.
3991 (read_struct_type): Add FIXME comments where it needs work
3993 (read_huge_number): Add FIXME about overflows.
3994 (read_range_type): Add FIXME about comparing a long to 1<<32.
3996 * coffread.c: Minor changes to move things closer to the new
3997 regime with symtab.c and dbxread.c Major work is still needed
4000 * exec.c (exec_file_command): Remove old variables (see core.c
4002 (xfer_memory): If memory transfer is right at the end of a
4003 section, don't lose.
4005 * findvar.c (get_saved_register): If value is in a real
4006 register, LVAL is lval_register, not lval_memory.
4008 frame.h: Declare print_sel_frame and record_selected_frame.
4010 gdb-int.texinfo: New file, for GDB internals documentation.
4011 Very simple, unformatted doc of cleanups is there for now.
4013 gdbcore.h: Remove obsolete variables that described a.out
4014 section addresses and offsets. (See core.c above.)
4015 Declare fetch_core_registers and registers_fetched.
4017 getopt.c: Declare char *alloca(); even on SPARC.
4019 infcmd.c (run_command): Call target_kill rather than
4021 (step_command, next_command, stepi_command, nexti_command):
4022 Declare from_tty parameter even though we don't use it.
4023 (run_stack_dummy): argument BUFFER is a char array, not
4024 a pointer to REGISTER_TYPE.
4025 (finish_command): using_struct_return needed a value *,
4026 not a struct symbol *.
4028 * infptrace.c (child_xfer_memory): To avoid dependency on
4029 where sections are in memory, try PT_WRITE_D and if that fails,
4030 try PT_WRITE_I. Most Unixes don't care which you use.
4032 * infrun.c (step_resume_break_shadow): Change to array to
4033 match other breakpoint shadow storage.
4034 (clear_proceed_status): Pass address of bpstat to
4035 bpstat_clear, not the bpstat itself.
4036 (child_create_inferior): FIXME comment about if the child
4038 (start_inferior): Remove old function.
4039 (child_open): Use target_kill rather than kill_inferior.
4040 (wait_for_inferior): Ditto.
4041 (insert_step_breakpoint, remote_step_breakpoint): Use
4042 new step_resume_break_shadow.
4044 * inftarg.c (child_wait): If all child processes die,
4045 pretend that the one being waited for exited with signal 42.
4047 * main.c (command_line_input): When scanning for comments,
4048 don't coredump on unclosed quotes.
4049 (quit_command): Use target_kill rther than kill_inferior.
4050 (_initialize_main): Rename class_user from "user" to
4053 * printcmd.c (print_command_1): Initialize "fmt" if no format
4054 is specified by the user.
4055 (print_frame_args): Only add to args_printed if we are
4056 actually fetching args from the stack (avoiding undefined
4058 (_initialize_printcmd): Remove bogus \{ from string.
4060 * remote-eb.c (eb_open): Avoid coredump on no argument.
4062 * remote-nindy.c: Bring out of Intel environment into new
4063 target environment. Remove all conditional compilation on
4064 I80960. Massive hacking throughout.
4065 (nindy_xfer_inferior_memory): New routine stolen from
4067 (nindy_create_inferior): New routine pieced together, probably
4068 not quite working yet.
4069 (nindy_ops): New target_ops struct for nindy.
4071 * remote-vx.c: Use write_memory rather than target_write_memory
4072 to get error checking.
4073 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4075 (vx_create_inferior): Use target_terminal_ours...
4077 * signame.c (_initialize_signame): Always initialize, since
4078 we need the table for things other than psignal.
4080 * solib.c (solib_add): Use symbol_file_add, not add_file.
4081 (solib_address): Return boolean result rather than struct
4082 pointer which nobody else knows the type of.
4084 * sparc-tdep.c, valops.c: Use write_memory rather than
4085 target_write_memory, to get error checking.
4087 * stack.c (locals_info, catch_info, args_info,
4088 get_selected_block, frame_command, up_command): Use
4089 target_has_stack, rather than have_inferior_p or
4092 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4094 * symfile.h: New file, defining the interface between the
4095 generic and object-file-specific symbol reading code.
4097 * symtab.c: Move generic symbol-reading interface to symtab.c,
4098 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4099 table to map BFD targets to symbol-reading modules in GDB.
4100 Change index to strchr.
4101 (lookup_struct_elt_type): Use error() rather than hand-made
4102 simulations thereof.
4103 (lookup_partial_symbol): Speedup slightly when length == 0.
4104 (symbol_file_add): New function.
4105 (symbol_file_command): Call it.
4106 (symfile_open, symfile_init): New function.
4107 (add_file_target_command, add_file_addr_command): moved from
4110 * target.c (target_command): use target_kill.
4112 * target.h (target_files_info): Don't declare, never called
4115 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4116 files to determine stack end address.
4118 * valarith.c (value_x_binop, value_x_unop): Change error message
4119 to be more useful. Pass proper argument to value_struct_elt.
4121 * valops.c (value_assign): FIXME comment that long long
4122 bitfields will break here.
4124 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4125 Update `make saber_gdb' to work better.
4127 * TODO: A woman's work is never done.
4129 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4130 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4131 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4132 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4133 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4134 valops.c, valprint.c, exec.c: Lint.
4137 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4139 Continuing Intel 960 port merge of GDB.
4141 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4142 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4143 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4144 Wack over "make depend" so it handles files in subdirectories
4145 vx-share, nindy-share, bfd, and in the current directory.
4147 * blockframe.c (get_prev_frame_info): Remove fatal error
4148 if stack not defined.
4150 * core.c (core_open, core_detach): New functions that handle
4151 the old "core-file" command as "target core" and "detach" instead.
4152 (core_file_command): Call them.
4153 (core_xfer_memory): Use common routine xfer_memory.
4155 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4156 dbxread now uses bfd for everything but symbol reading itself.
4157 BFD internals are used to drag out the relevant file offsets.
4158 (partial_symbol_file_open): Change args all around for BFD.
4160 * symtab.c: Rename "value" to "val" everywhere, so we can
4162 (symbol_file_command): New command, moved from dbxread.c
4163 and coffread.c. It uses BFD to read the file, then vectors
4164 based on its type, to dbx or coff symbol readers.
4165 * symtab.h: Extern a few vars for symbol_file_command.
4167 * target.h: Breakpoint takes a char * save area, not a char **.
4169 * valprint.c (val_print): When unpacking bitfields, offset
4170 the address in gdb of the value, if it is declared with a shorter
4171 type. Remove the last "runtime kludge test" of host byte order.
4173 * utils.c: Remove old my_bfd_read routine.
4175 * stack.c (frame_info): Use target_has_stack. Print program counter
4176 register's actual name rather than "pc", since it's called the
4177 "ip" (instruction pointer) on the i960 (sigh).
4179 * target.c (target_command): Add command for selecting a target
4180 type and calling its open routine. This is used for initiating
4181 communication with a particular target, in a generic way.
4183 * tm-i960.h: Update for modern gdb. Remove semicolons from
4184 various macros. Handle reading struct return convention, and
4185 error-out attempts to return structs with the "return" command.
4186 Be sure gdb doesn't think we know how to call functions in the
4189 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4190 to i960_xxx in lower case.
4191 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4192 not being defined yet.
4194 * remote.c (remote_open): Call start_remote to initialize
4195 wait_for_inferior during open.
4196 (remote_xfer_inferior_memory): Return length written rather
4199 * remote-vx.c (target_command -> vx_open): Use new generic
4201 * remote-eb.c, inftarg.c, exec.c: ditto.
4203 * infrun.c: Fix comments.
4204 (attach_program -> child_open): Use new generic target command.
4205 (wait_for_inferior): Clear saved register values before target_wait,
4206 so target_wait can set some of them if convenient.
4208 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4209 Return success indicator, not void.
4210 (child_xfer_memory): Avoid fetching initial word if we'll
4211 overwrite it anyway.
4213 * infcmd.c (attach_command): Use new generic target open routine.
4214 (_initialize_infcmd): Update doc on attach and detach commands.
4215 (do_registers_info): Merge in a byte-order problem as a FIXME
4218 * findvar.c (find_saved_register): Avoid problem in current frame.
4219 (read_relative_register): Ditto.
4220 (write_register): Convert byte order on the way out.
4222 * exec.c (file_command): Add.
4223 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4224 (xfer_memory): Common function between core_xfer_memory and
4226 (exec_xfer_memory): Use it.
4228 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4230 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4231 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4232 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4234 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4236 Merge Intel 960 port of gdb, continuing...
4238 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4239 symbol_file_command): Pass from_tty arg to hush 'em up.
4241 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4242 Add magic numbers for 960 COFF format.
4244 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4246 Merge Intel 960 port of gdb, from Intel "1.2" release.
4248 CHANGE_LOG entries from their port, which was based on
4251 Thu Sep 6 11:02:22 PDT 1990
4252 Remove temp file if download is interrupted.
4254 Wed Aug 1 09:08:33 PDT 1990
4255 Now uses binary protocol to talk to NINDY.
4256 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4257 Times out after 5 seconds when trying to talk to NINDY.
4259 Tue May 29 12:54:49 PDT 1990
4260 Added variable baud rate (-b switch).
4261 Source code reorganization.
4263 Thu Apr 26 11:09:55 PDT 1990
4264 More cleanup of batch mode; specifically, execute "-s", "-e", and
4265 "-se" switches as soon as they are encountered on the invocation line.
4267 Fri Apr 20 13:47:15 PDT 1990
4270 Thu Apr 19 09:54:28 PDT 1990
4271 Add 'reset' command.
4273 Wed Apr 18 09:48:07 PDT 1990
4274 After opening remote tty, wait for 1 second to go by without input
4275 from it before trying to talk to NINDY (fixes problems with the
4276 Heurikon HK80/V960E).
4278 Mon Apr 4 16:33:05 PDT 1990
4279 Some output was not being suppressed in 'batch' mode.
4281 Thu Mar 22 15:31:11 PST 1990
4282 Ask user if old symbol table should be deleted when new file is
4285 Allow user to run a program downloaded before gdb960 was brought up.
4287 Correct "exec-file" help message for i80960 context.
4289 Correct bug in calculating user space address: could occasionally
4290 corrupt user program.
4292 Make sure to zero low-order bits in rip's because of bug in 960CA
4293 A-step part: could cause operation faults when "next"ing across
4296 Correct bug that made it impossible to get source line numbers for
4297 code loaded at addresses higher than 0x7fffffff.
4299 Wed Jan 10 12:43:22 PST 1990
4300 Open remote tty for exclusive use.
4302 Fri Jan 5 12:14:42 PST 1990
4303 Correct disassembly (CA manual was right after all):
4304 opcode for sysctl is 0x659
4306 Mon Oct 23 12:03:04 PDT 1989
4307 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4309 Mon Oct 16 14:15:09 PDT 1989
4310 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4312 Mon Oct 2 15:56:31 PDT 1989
4314 Added 960CA disassembly support.
4316 To simplify maintenance:
4317 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4319 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4320 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4321 - made disassembly interface identical to that in gdmp960.
4325 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4327 * target.h: Allow targets to stack. Add target_has_memory,
4328 _registers, etc. Restructure memory access and "info files"
4329 to walk the target stack.
4330 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4331 target.c: Change tables to match target.h.
4332 * inflow.c (child_mourn_inferior): pop child_ops.
4333 (generic_mourn_inferior): Use new has_stack flag.

4336 * remote-eb.c: New memory regime, new info files.
4337 * remote-vx.c: New memory regime, new info files. Now use
4338 separate targets for VxWorks attachment to machine, and
4339 actually running a process under VxWorks, since one has
4340 stack & execution & regs and the other doesn't.
4341 * remote.c: New memory regime, new info files.
4342 * sparc-xdep.c (fetch_core-registers): New memory regime.
4343 * target.c: New routines and support for stacked targets,
4344 new memory regime, new info files regime.
4347 Generalize section handling for an arbitrary number of sections,
4348 including use of the new BFD (binary file) library.
4349 * gdbcore.h: Add struct section_table.
4350 * exec.c (build_section_table): Iterate all sections and
4351 record what gdb needs to know about them.
4352 (exec_command): Use it.

4357 * source.c (find_source_lines): Use bfd_get_mtime.
4358 * dbxread.c: Quick changes to make it compile with new BFD.
4359 * utils.c (error): Avoid using bfd_error in generic routines.
4361 * core.c (core_fetch_registers): Get from the ".regs" section of
4363 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4365 * inferior.h (attach_flag): Export.
4366 * infcmd.c (run_command): use new target_create_inferior.
4367 * infrun.c (child_create_inferior): Don't return result.

4370 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4372 * breakpoint.c (bpstat_num): Handle breakpoints which have
4373 since been deleted, such as temporary breakpoints.
4374 infcmd.c (program_info): ditto.
4376 * core.c (core_file_command): Display the frame where the core
4381 * remote-vx.c (target_command): Merge in target command from
4382 targ-vx.c. A few other cleanups.
4384 * TODO, Projects: Lots more stuff to do...
4386 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4388 Massive changes to wall off the remote-debugging interface
4389 behind a function vector. The port to handle VxWorks targets
4390 is also part of this.
4392 All files: Replace references to renamed functions,
4393 remove references to remote_debugging, remove references to
4394 have_include_file, have_core_file in favor of target_has_stack,
4395 target_has_memory, etc.
4397 * Modularize the breakpoint interface.
4398 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4399 a breakpoint instruction.
4400 breakpoint.c: struct breakpoint's shadow_contents now sized as
4402 (insert_breakpoints): Vector to target to install breakpoints.
4403 (remove_breakpoints): Vector to target here too.
4404 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4405 sparc-tdep.c (single_step): Use new breakpoint interface for
4406 the single-step breakpoints.
4407 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4408 New file, contains routines to insert and remove breakpoints by
4409 reading out the old contents and later replacing them. This is
4410 how ptrace breakpoints work, and many remote systems as well.
4412 * tm-vxworks68.h: New config file, overrides a few things for
4413 Wind River's preferences.
4415 * target.h: New file, for transfer vector used to talk to the
4416 inferior (child, attached, core, exec, remote, etc). All accesses
4417 to the thing being debugged should come through these vectors.
4418 target.c: New file, routines to handle transfer vector.
4419 (various files): Add transfer vectors XXX_ops for the various
4420 targets and pseudo-targets (core files, etc) we support.
4422 * breakpoint.c (bpstat_stop_status): Further explorations of
4423 watchpoints and why things don't work all the time.
4424 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4426 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4427 the local gdbinit if it doesn't already have it.
4429 * core.c (core_ops): add and install.
4430 Allow core debugging without exec file.
4432 * dbxread.c (free_and_init_header_files): Merge two fns.
4433 (end_symtab): Free named symbol table when a new version comes in.
4434 (read_dbx_symtab): Relocate all kinds of symbols with base
4435 address. First step toward handling different text, data, bss
4437 (add_file_addr_command): Renamed add_file_command.
4438 (add_file_command): Vector to remote handler.
4439 Add "load" as an alias for "add-file" command.
4441 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4442 non-returning functions.
4444 * exec.c: Add exec_ops, and push it as a target when an exec
4447 * infcmd.c (run_command): Pass executable file name and arg list
4448 separately when starting an inferior. Permit "run" when no exec
4449 file is specified, for VxWorks.
4450 (detach_command): Move to child_detach in inftarg.c.
4452 * inftarg.c: New file. Unix-child-specific routines, and the
4453 child_ops structure.
4455 * inferior.h (registers): Export "registers" as the way for
4456 target dependent register handlers to find gdb's local copy of
4457 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4458 since it is now used by places that want wait_for_inferior to
4459 handle the grunge but want to see every trap from the inferior.
4461 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4462 Eliminate remote_debugging hooks in terminal handling.
4464 * infrun.c: Replace start_inferior with child_create_inferior.
4465 Move all the hair of Unix shells and ptrace idiosyncracies into
4466 child_create_inferior, so remote handlers don't have to deal.
4467 Remove running_in_shell. Rename stop_after_attach to
4468 stop_soon_quietly, and use it in a few other places where we want
4469 to just call wait_for_inferior and get control back on the first
4470 trap. trap_expected now never takes a value > 1.
4471 (init_wait_for_inferior): Initialize static vars when a new
4474 main.c (gdbinit): Add new hook for .gdbinit file name, let
4475 it be overridden by config files as GDBINIT_FILENAME.
4476 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4477 Both of these are used for VxWorks gdb.
4479 mcheck.c: rename include file "gmalloc.c" to avoid problems
4480 with system include file "malloc.c".
4482 param-no-tm.h: New include file, same as param.h but does not
4483 include the default "tm.h" file. This is used in files where
4484 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4486 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4488 remote-vx.c: New file, VxWorks remote debugging support. Uses
4489 RPC routines that are shared with the target system, in directory
4492 remote.c: Vectorize remote interface.
4494 source.c: Globalize source_path, and make an alias "l" for "list"
4495 since we now have the "load" command.
4497 sparc-xdep.c: Use new param-no-tm.h.
4499 symmisc.c (free_named_symtab): Add new function from Wind River.
4500 However, ifdef it out for now while we think about what it should
4503 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4505 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4506 non-Unix-children handle this with their own code in the target
4509 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4510 source and target lists. Add vx-share to default list of include
4511 directories. Add new files to src and target lists: mem-break,
4512 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4513 ${srcdir} versions of munch and createtags are used.
4515 * valops.c (find_function_addr): Split out of call_function.
4516 (call_function_by_hand): Rename call_function; this function
4517 calls functions in the target by laboriously patching the target
4518 word-by-word with the right stack, args, regs, etc.
4521 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4523 Handle AMD 29000 a bit better.
4525 * remote-eb.c (readchar): Mask received char log to make it readable.
4526 (remote_start): Pass arguments down to executing program.
4527 Make startaddr unsigned.
4528 infrun.c (start_inferior): Accept args, pass them to
4530 infcmd.c (run_command): Pass args down to start_inferior.
4532 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4533 the target object file format.
4534 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4536 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4537 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4539 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4541 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4542 * TODO: We did a few things, we have more to do though.
4544 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4545 * inflow.c (inferior_died): Clear deferred stores.
4547 * Debug problems with dummy frames and calls to the inferior.
4548 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4549 * sparc-tdep.c (do_restore_insn): Simplify.
4550 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4551 (sparc_push_dummy_frame): Simplify and fix what we push.
4552 (sparc_pop_frame): Slightly more hair here, deciding whether
4553 we are restoring a saved PC or returning to a return address in %i7.
4554 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4556 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4557 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4558 * obstack.h (chunkfun): ditto.
4559 * defs.h (xmalloc, xrealloc): ditto
4561 * utils.c (quit): Grab the terminal from the child if necessary.
4563 * inflow.c (term_status_command): Rename to term_info, change
4566 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4567 (is_delayed_branch): Speed up.
4568 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4569 Still missing some float ops, and needs testing.
4571 * Support for input and output radixes other than base 10
4572 * defs.h (input_radix, output_radix): Declare.
4573 * expread.y (yyparse, parse_number): Handle changes of input
4574 radix, and ambiguous names-or-numbers in radixes >10.
4575 * printcmd.c (print_scalar_formatted): Print formatted hex
4576 numbers in varying column widths.
4577 * valprint.c (val_print): Use output_format to print scalar ints.
4578 (set_input_radix, set_output_radix, set_radix): Create.
4579 (set_output_radix): Set output_format from output_radix.
4580 (_initialize_valprint): add `set radix' but leave the others off.
4582 * main.c (execute_command): Let stupid questions be turned off.
4583 (_initialize_main): Handle "set stupidity", etc.
4585 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4586 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4588 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4590 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4591 bfd stuff is still screwed up, but with some manual work, it
4594 * breakpoint.c (bpstat_do_actions): Start over if a command
4595 proceeds the inferior, since the inferior will have stopped and
4596 will need to have its new stop-actions taken care of.
4598 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4599 compiler fits, simplify it.
4601 * gdb.texinfo (directory command): Doc new dir command.
4602 source.c (directory_command): "dir" now puts things on the front
4603 of the path, moves dups up front, and handles multiple names
4604 on the command line, inserting each one in order. It also
4605 blows away cached line and full_filename info.
4607 * stack.c (backtrace_command): Skip "more stack frames follow"
4610 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4611 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4612 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4613 The only odd one was Gould NP1, which had defined vprintf to
4616 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4617 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4618 variable, inspect_it.
4619 valprint.c (print_string, val_print): Use the global inspect_it
4620 to indicate whether to print in Epoch style or normal style.
4622 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4624 * printcmd.c (call_command): add an alias for the "print" command
4625 which runs expressions and doesn't print the result if void.
4626 (print_command_1): implement it.
4628 * command.c: Remove #if 0'd code. Initialize all the fields
4629 in add_cmd (). Rename do_nothing_command to
4630 not_just_help_class_command, and make it externally visible.
4631 command.h: add user_commands to struct.
4632 * main.c (define_command): Don't overload c->function with a char
4633 string as well as a function pointer.
4635 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4636 calling convention of value_struct_elt () that got dropped in
4639 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4640 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4642 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4644 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4645 until a good time (e.g. when we are about to run the child),
4646 saving ptrace calls.
4647 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4648 * tm-sparc.h: define DO_DEFERRED_STORES.
4650 * sparc-xdep.c (store_inferior_registers): when storing float
4651 registers, don't store stack regs too. When storing the SP,
4652 however, DO store the stack regs too. This fixes a bug in which
4653 the dummy frame is not recognized when a call_function finishes,
4654 because its frame pointer (in the stack regs) was never
4656 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4657 even though we don't know how to read them from an inferior.
4658 valops.c (call_function): Comment about storing SP.
4660 * infrun.c (save_inferior_status): Save away the original bpstat
4661 chain so it can be restored later. Install the copied version for
4662 use by whoever saved the status. It will be blow away by
4663 restore_inferior_status, and the original chain restored. This is
4664 important for people who have pointers into the original.
4666 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4667 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4668 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4671 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4673 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4674 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4675 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4677 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4679 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4680 Store the baseclasses in a type struct starting from array element
4681 0 rather than from the unusual array element 1.
4683 dbxread.c: the above.
4684 (virtual_context): Add
4685 Read new debug information about which virtual function table
4686 a virtual function is from, and store it in fn_field.fcontext.
4688 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4689 TYPE_FN_FIELD_STATIC_P.
4691 symtab.c: the above.
4692 valops.c: the above. Handle pointer casts of object *'s.
4693 (search_struct_method): Add.
4694 (value_struct_elt): First arg is now a pointer to a value, and is
4697 valprint.c: the above.
4698 values.c (value_virtual_fn_field): Add type arg. Handle
4699 offsetting to the proper object when calling virtual fns.
4701 (baseclass_addr): Add valuep arg.
4703 * README: Document the current state of BFD config (missing).
4704 * TODO, ChangeLog, Makefile.dist: Roll version.
4705 * WHATS.NEW: Add summary of changes since 3.5.
4707 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4709 * dbxread.c (read_struct_type): Clear bit vectors whenever
4711 symtab.c (B_CLRALL): define.
4713 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4714 using == rather than =. Huh... This fixes the dreaded problem
4715 wherein builtin_type_int becomes TYPE_CODE_FLT.
4717 * core.c (info_files): Show the inferior pid.
4719 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4720 already knows how to look in the source directory.
4722 * Remove psymtab hair from many places. Remove duplicated code
4723 for searching symbol tables. Hide psymtabs from most places.
4724 Make it fast to get from a psymtab to its symtab.
4726 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4727 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4728 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4729 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4730 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4731 new symtab completely. New psymtabs get symtab pointer
4732 initialized to zero. Remove MI warning printf.
4733 symtab.h: Comments. Add psymtab to symtab pointer.
4734 (PSYMTAB_TO_SYMTAB): New macro.
4735 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4736 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4738 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4740 (print_frame_info): Avoid special-casing symbols that have not yet
4743 * source.c (open_source_file): Quick path if we have already
4744 located the source file by its full name.
4746 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4747 find_pc_psymtab. When a name is found in the misc function
4748 vector, search the symbol table for its mangled name, not the
4749 name that the user typed.
4751 * bfd.h: Fix missing comment terminators, make #endifs match.
4753 * valarith.c (value_less): Handle unsigned int comparisons.
4754 Add FIXME about pointer compares, which assume host and target
4755 pointers are the same.
4757 * command.c (do_nothing_command): lint
4758 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4759 fix comments on debug symbol format for visibility. Actually set
4760 visibility of symbols.
4761 main.c (echo_command): lint; use <readline/history.h>.
4762 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4763 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4764 pointing past end of allocated memory; saber complains.
4765 obstack.h: Declare the external functions that we use.
4766 valarith.h: use <string.h>
4767 solib.c (solib_add): lint.
4769 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4771 * main.c (initialize_main): Default info_verbose to off, now that
4772 symbol reading is fast.
4773 (quit_command): Avoid clobbering exec_bfd while quitting.
4775 * Initial BFD (binary file diddling library) merger:
4776 coffread.c: Change AOUTHDR to struct exe_hdr.
4778 core.c: initialize initialized data at compile time.
4779 (core_file_command): Move from coredep.c, convert to bfd.
4780 (xfer_core_file): Convert to bfd.
4781 exec.c (exec_file_command): use bfd routines.
4783 mips-tdep.c: Remove exec_file_command and friends.
4786 * coredep.c: (fetch_core_registers) Convert core_file_command to
4787 fetch_core_registers.
4788 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4790 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4791 (my_bfd_read): More bogosity, which I don't think we call.
4792 (program_name): Remove this atrocity asap!
4794 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4797 values.c: allocate_repeat_value was not clearing the
4798 optimized_out field.
4799 (value_static_field): minor stylistic fix (wrong macro was used).
4800 valops.c (value_struct_elt_for_address): didn't work for C++
4803 * signame.c (_initialize_signame): Initialize signal names once.
4805 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4806 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4807 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4809 * remote-eb.c: Support user-settable baud rates on the serial port.
4811 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4813 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4815 * tconfig/sun3os4: Remove warning about native assembler,
4816 since it also occurs in the xconfig file.
4818 * findvar.c (registers): Allocate some slop after `registers'
4819 to prevent stray accesses from trashing the next variable.
4821 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4822 on the sun-3, by changing the #ifdef from `sun3' (which is not
4823 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4824 vars, which happened to follow `registers' in the executable.
4826 * readline/history.c (history_search): Heed gcc-2's advice
4827 and parenthesize && inside ||).
4829 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4830 tm-29k.c: Insert FSF copyright headers.
4832 * remote-eb.c: Better comments.
4834 * Makefile.dist: Update to 3.91.6.
4835 * TODO: note PREPARE_TO_STORE problem.
4837 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4839 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4841 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4843 * infrun.c (wait_for_inferior, at end): Don't set up
4844 prev_* if the inferior no longer exists.
4846 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4847 CANNOT_EXECUTE_STACK.
4848 valops.c (call_function): Use it.
4850 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4852 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4853 infrun.c (wait_for_inferior, 2 places): Use it.
4855 * values.c (value_being_returned): Only use
4856 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4858 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4859 right thing for remote-eb.c.
4861 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4862 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4864 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4865 (FRAME_FIND_SAVED_REGS).
4867 * findvar.c ({fetch,store}_registers): Check for
4868 REMOTE_{FETCH_STORE}_REGISTER macro.
4870 * findvar.c (get_saved_register): Add argument lval and
4871 change meaning of argument addr.
4872 findvar.c: Change calls to get_saved_register to reflect
4873 new calling convention.
4874 valops.c (value_assign): Use get_saved_register instead of
4875 find_saved_register.
4877 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4879 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4880 an (uninitialized) pointer to one. Use "&" when passing it
4883 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4885 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4888 * coffread.c (symbol_file_command): Put semicolon after
4890 Put safe_to_init_tdesc_context in #if defined (TDESC).
4891 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4892 coffread.c: #include <sys/stat.h>.
4893 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4894 Add missing ')' in check for "lc%" and friends. Remove
4896 Declare read_one_sym() at top of file.
4897 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4898 MC68WRMAGIC can have the same value without causing a duplicate
4901 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4903 * Allow a Makefile to be built without building the
4904 tm and xm file links that screw up builds in subdirectories.
4905 This is done with `config.gdb none', then you can do things
4906 like `make gdb.tar.Z'.
4907 * tconfig/none: Config file for no target system
4908 * xconfig/none: Config file for no host system
4909 * config.gdb: If no TM or XM files are called out by the
4910 host or target file, don't make links for them.
4912 * cplus-dem.c: Add documentation.
4914 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4915 simple error, so the user's gdb doesn't crash due to some object
4916 file problem (e.g. somebody is rebuilding the file out from under
4919 * printcmd.c (print_address_symbolic): demangle the symbol.
4921 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4922 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4923 (alldeps.mak): sort and uniq all results from this; duplicates
4924 hose gdb.tar.Z link building. Remove RCS files from
4925 tconfig and xconfig. Add config files for sun386. Add
4926 a few odd files to OTHERS and HFILES.
4928 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4930 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4931 Roll version number to 3.91.5. Make lint work in bindir.
4933 * README: Document cross-debugging and new file structure.
4935 * blockframe.c: Lint. Include "value.h" to declare read_register.
4936 (find_pc_partial_function): remove duplicate line.
4938 * command.h: Lint. Declare error_no_arg and dont_repeat.
4940 * tm-news.h: Remove inadvertently duplicated stuff.
4942 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4943 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4945 * config.gdb: Allow `config.gdb host target' form. Clean
4946 up previous change that printed bogus messages when you just said
4949 * core.c: #include "command.h" for lint.
4952 * main.c: Remove some casts of enums. Lint.
4959 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4961 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4962 read it from memory. This will allow us to save ptrace calls
4963 eventually. Changed caller single_step too.
4965 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4966 that we aren't going to use, saving many ptrace calls, especially
4967 when watchpointing or single stepping. Use some #define's for
4969 (store_inferior_registers): Ditto.
4970 (core_file_command): Use some #define's for constants.
4972 * tm-sparc.h: Add #define's for some register numbers, so we
4973 can eliminate the use of random constants in sparc-xdep.c.
4975 * stack.c (frame_command, print_frame_info, up_command,
4976 down_command) Remove frame_changed, since it
4977 causes a bug and doesn't seem to do anything useful. In some
4978 places it was used as a flag, in others as a stack level (?).
4980 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4981 default is to use the portable (vprintf) version rather than the
4983 * xm-news.h (MISSING_VPRINTF): Add.
4985 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4987 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4989 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4990 about linking debugged programs -Bstatic in the sun?os4 config
4991 files in tconfig and xconfig subdirectories.
4993 * main.c (main): Remove unreached exit(0) now that we exit
4996 * Create TODO file for online bug list. There are too many
4997 "little" bugs to keep track of on paper.
4999 * Change Projects file to refer to bug-gdb@cygnus.com
5000 rather than kingdon@ai.
5002 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
5004 * Makefile.dist (VERSION): 3.91.4 now.
5006 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
5007 (condense_misc_bunches): Add sanity check that misc_count is
5008 the same as the number of symbols in the bunch.
5010 * coffread.c: rename init_misc_bunches. Pass an argument
5011 to condense_misc_bunches (a zero).
5013 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
5014 every time we are called; don't rely on our caller to do it.
5015 (add_file): Remove call to init_misc_bunches.
5017 * mipsread.c: Only warn, don't error, if unknown symbol types.
5018 This keeps an old gdb from falling on its face if it sees newly
5019 extended symbol info. Rename init_misc_bunches.
5021 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
5023 * Merge in changes from Per Bothner for DECstations and other
5024 MIPS stuff. The rest is Bothner speaking:
5026 The next message is a merger of Alessando Forin's mips port with
5027 mine. I've tried to use my good if biased judgment to get
5028 the best of both. It *does* need testing.
5030 Some of the changes are general, *not* mips-specific.
5033 Didn't believe in little-endian bit order.
5034 There are still inconsistencies about whether flags
5035 like BITS_BIG_ENDIAN are integer (#if ...) or
5036 boolean (#ifdef ...). I tried to paper over them.
5038 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5039 Moved some misc_function code that was common to
5040 {dbx,coff,mips}read.c to symtab.c.
5041 In the process, I think I cleaned things up a bit.
5042 At the same time, moved obsavestring and obconcat to symtab.c.
5045 Removed obsolete condense_addl_misc_bunches (use
5046 condense_misc_bunches(1) instead).
5049 Needed to include <sys/dir>, at least on DECstations.
5051 valops.c, mips-tdep.c, tm-mips.h:
5052 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5053 conventions (when STACK_ALIGN is insufficient).
5054 Needed on mips, where doubles need 8-byte alignment,
5055 but ints only need 4.
5058 Removed cruft that was not being used.
5059 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5062 Print $ before register-names (I think that makes things a little
5064 Never print two instructions, even if one delays.
5065 Removed hex-disassemble set_cmd. (This is not mips-specific,
5066 so I think the argument is whether it is generally worthwhile or not.
5067 I'm inclined to think not, given how easy it is to
5068 convert between radixes in gdb.)
5071 This is basically Alessando's code.
5072 It doesn't use obstacks; I changed it to use obstacks
5073 in a few minor places where using malloc causes a
5074 memory leak. (Probably, more places could/should be changed.)
5075 I added record_misc_function where it was missing.
5076 In symbol_file_command and add_file_command, I tried
5077 to make the code consistent with more recent versions.
5078 Minor sylistic changes in parse_procedure.
5079 Make a .gdbinfo. psuedo-symbol point back to the real
5080 procedure symbol (using the isym field).
5083 This is basically from my port, but with a lot of details
5084 and a number of routines merged in from Alessando's version.
5085 I basically used my code "raw" backtrace (use heuristics
5086 from the actual code, rather than symbol table info) - though
5087 the idea is Alessandro's. I feel my code is a little cleaner
5088 here, particularly in being a little more flexible, such as being
5089 able to handle gcc-produced code (which it now can).
5090 It also doesn't do frame caching (which is not useful
5091 more recent gdb versions).
5092 I also used my code for push_/pop_dummy, more or less.
5093 I tried to incorporate AF's code for testing sigtramp
5094 while backtracing; I probably got it wrong.
5095 Added mips_print_register, which tries to scrunch as much
5096 information as possible on a screen...
5097 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5098 under mips-pinsn.c), I don't see anything mips-specific here,
5099 and I don't see it being all that useful anyway.
5102 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5103 Use more register names (rather than hard-cases numbers).
5105 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5107 * Hack up 3.90.11 changes:
5109 * Makefile.dist (depend): parameterize $(GCC).
5110 Add solib.c and solib.o.
5111 (readline): Fix vpath for both absolute or relative SRCDIR.
5113 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5114 Also, let the part I didn't understand at least compile so
5115 I can test the rest. FIXME.
5117 * dbxread.c: Fix thinko using strcmp.
5118 (init_psymbol_list): declare static.
5119 (partial_symbol_file_open): Comment cleanups better, avoid
5120 cleaning up the string table since the caller will do that.
5121 Move the stat for mod time into symbol_file_command, temporarily.
5122 (There should be a mod time for each symbol file, eventually,
5123 to control its rereading. FIXME.)
5125 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5126 SunOS, which gives error for shared libs otherwise. (From
5127 Schaefer, probably FIXME needs work for portability.)
5129 * solib.c: Move #include "param.h" to work.
5130 Lowercase all the Uppercase Letters In the Messages.
5131 (find_solib): Clean up inferior_so_name for debug printouts.
5132 Allow no argument, to mean all shared libraries.
5134 * symmisc.c: include param.h to get CLEAR_SOLIB.
5136 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5138 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5139 to 3.90.11. ChangeLog entries below are from this.
5141 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5145 * Makefile.dist (HFILES): Add tm-sunos.h.
5147 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5151 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5153 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5155 * sparc-opcode.h Added single-operand version of rett.
5157 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5159 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5160 Put parens around gcc_p in expansion.
5162 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5164 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5166 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5168 * Changes for Sun shared libraries:
5169 blockframe.c (find_pc_partial_function): If a non-text symbol
5170 is found, set *address = pc - FUNCTION_START_OFFSET.
5171 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5172 Disable breakpoints instead of giving an error.
5173 source.c (select_source_symtab): Initialize cs_pst.
5174 symmisc.c: Call CLEAR_SOLIB if defined.
5175 symtab.h: Make text{low,high} CORE_ADDR not int.
5176 (psymtab): New field addr.
5178 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5179 (record_misc_function): Give correct type for N_DATA symbols.
5180 (condense_misc_bunches): do "misc_function_count = j" regardless
5182 Take code which is shared between symbol_file_command and
5183 add_file_command and put it into partial_symbol_file_{open,read}.
5184 Split add_file_command into add_file_command and add_file.
5185 Make psymtab_to_symtab read in the string table if the file
5187 Two new parameters to read_dbx_symtab and start_psymtab.
5188 tm-sunos.h: New file.
5190 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5192 * infcmd.c: Change cont_command to continue_command and "cont"
5195 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5197 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5199 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5201 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5202 size 1,2,4,8 rather than size < 8.
5204 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5205 as necessary, not just once.
5207 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5209 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5211 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5213 * tm-news.h: Add CALL_DUMMY_*.
5215 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5217 * config.gdb: In list_host, list_target, use ${i}, not $i.
5219 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5221 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5223 * sparc-opcode.h: Change all store floating-point state register
5224 instructions to have the right match & lose fields.
5226 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5228 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5230 config.gdb: If srcdir != ., create readline directory and
5231 copy a makefile into it.
5233 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5234 consistency with POSIX.
5236 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5237 when we exit its exp_valid_block.
5239 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5241 * Makefile.dist: Bump version to 3.91.3.
5243 * Clean up handling of breakpoint commands (somewhat).
5244 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5246 inferior.h: Add breakpoint_proceeded to inferior status struct
5247 and globals; save it and restore it.
5248 (clear_breakpoint_commands): Cleanup, remove old #define.
5250 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5251 (save_inferior_status, restore_inferior_status): handle it also.
5252 (proceed): Remove earlier code that set breakpoint_proceeded.
5253 It is now set only in clear_proceed_status.
5254 (clear_proceed_status): Cleanup, use bpstat_clear rather
5255 than clear_breakpoint_commands. No callers need the stop_bpstat
5256 between clear_proceed_status and proceed.
5258 infcmd.c: Add breakpoint_proceeded definition and comment.
5259 (cont_command, jump_command, signal_command): Move call to
5260 clear_proceed_status right next to call to proceed.
5262 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5263 caller's argument while running down the chain of breakpoints.
5264 Use new variable "breakpoint_proceeded" to determine when
5265 a command that it executes moves the inferior past the
5267 (bpstat_clear): Handle NULL argument.
5268 (bpstat_clear_actions): Avoid useless call to
5269 breakpoint_auto_delete.
5270 (delete_breakpoint): Clean up bpstat's that are pointing to
5271 the deleted breakpoint from the stop_bpstat chain.
5272 (breakpoint_auto_delete): Simplify.
5274 * Clean up handling of EOF, error on stdin, etc. This was
5275 prompted by a network problem that caused gdb to go into an
5276 infinite loop filling up its malloc'd memory.
5278 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5279 not clear_breakpoints_commands, which is now gone.
5280 (main): If command_loop returns (e.g. from EOF on stdin), do
5281 a quit_command (looping back to command_loop if quit_command
5282 doesn't really quit).
5283 (command_loop): check result from command_line_input and
5284 exit if it returns NULL, rather than passing the NULL to
5286 (gdb_readline): Free malloc'd result space before returning
5289 * utils.c (query): Handle C-d to mean "yes", just as if the
5290 input was not a terminal. Also avoid infinite loop if EOF
5291 occurs in mid-input-line before newline. This allows
5292 query to be used at EOF on stdin with reasonable results.
5294 * infrun.c (proceed): Set breakpoint_proceeded.
5296 * values.c (value_as_long): Avoid infinite recursion for enums.
5297 (_initialize_values): Fix typo in help msg (kingdon).
5299 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5300 RL_LIB for linking. This allows -lreadline for linking
5301 and nothing for dependencies, once readline is a real library.
5303 * config.gdb: Jim Kingdon: give useful error message if the
5304 host or target type is not recognized.
5306 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5307 it just defines it. Dumb, but deal with it.
5309 * Jim Kingdon suggests:
5310 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5312 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5314 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5316 * Clean up Bothner's changes.
5318 * blockframe.c (clear_pc_function_cache): New function.
5319 * blockframe.c: remake cache_pc_function_* static.
5320 * dbxread.c (symbol_file_command): remove references to
5321 cache_pc_function_* variables.
5322 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5323 * printcmd.c: Avoid kludging a global variable (addressprint)
5324 to avoid printing the address of a string twice. Instead,
5325 pass the format letter 's' down low enough that it can be seen
5326 to avoid this problem.
5327 (print_formatted): Pass format arg to value_print.
5328 (restore_addressprint): Remove function.
5329 (do_examine): Avoid hacking addressprint, cleanups and such.
5330 (print_frame_args): Add a comment to a Bothner change.
5331 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5332 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5333 to wipe out the values cached in blockframe.c.
5334 * symtab.c (find_method): Add comment saying how big you must
5335 allocate to be "big enough". Per being terse again.
5336 * valprint.c (val_print): Handle format letter "s" to print
5337 strings without addresses. Add comment to vtbl printing code
5338 which casts with wild abandon. Rearrange reference-printing
5340 @0xaddr: value (print w/addressprint)
5341 value (print w/~addressprint)
5342 @0xaddr (parameter lists w/addressprint)
5343 or nothing (parameter lists w/o addressprint)
5345 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5347 * Merge more changes from Per Bothner:
5349 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5350 annoying) that I tried to improve it. Here are my suggestions.
5352 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5355 Do automatic de-reference when taking the address of a reference.
5357 Don't deref_ref when printing parameter lists.
5359 More attempts at treating refernences properly.
5361 In val_print, if deref_ref==0, don't print dangling " = ".
5363 Add COERCE_REF macro, which de-references an REF.
5365 * Merge changes from Per Bothner:
5367 * Fixed (Sony news)-specific configuration problems.
5368 * Fixed other problems with using vanilla pcc and libc (enum problems;
5369 assumption that vsprintf exists).
5370 * Some major speed-ups (finc_pc_partial_function now caches a match;
5371 parsing avoids duplicate symbol_lookup calls).
5372 * Changed handling of baseclasses (no longer use baseclasses field
5373 of struct type, use the first n_baseclasses fields instead).
5374 * Various minor changes/fixes, most C++-related.
5377 Cache the most previous match from find_pc_partial_function.
5378 (Save both low and high ends of matching function's pc range.)
5379 This speeds up the loop of infrun.c:wait_for_inferior quite
5380 a bit, and makes step/next commands much zippier.
5382 Added an enum->int cast (otherwise, some compilers barf).
5384 No longer set baseclass offset to 0, since multiple
5385 inheritance now mostly works.
5386 Added a number of casts, to shut up compiler warnings
5387 (after stabs where made enums, not ints).
5388 When discarding a symbol table (in symbol_file_command),
5389 must clear the cache introduced in blockframe.c.
5390 Don't convert $vtbl_ptr_type to vtbl any more.
5391 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5392 Mask off sign bit emitted by g++ for virtual table offset.
5393 Set voffset to -1 (not 1) for static member functions.
5395 Changed parsing/lexing of names to avoid doing symbol lookup twice
5396 (once when lexing to determine symbol class, once for real).
5397 Now only call symbol_lookup once. Fields of 'this' win especially big.
5399 Subpress printing addr twice in the case of 'x/s addr'.
5401 lookup_basetype_type is no longer used.
5402 Add find_methods as recursive helper function to decode_line_1.
5403 This allows multiple inheritance to work.
5404 Also, once one or more matches has been found, do not look in
5405 base-classes. (Baseclass methods would be overridden, anyway.)
5407 Removed baseclasses array in struct type.
5408 Instead of using baseclasses[i], use fields[i-1].
5409 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5410 Changed sign convention of voffset (previous was inconsistent).
5412 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5414 Used to assume existence of vsprintf. Re-written to not need it
5415 if HAVE_VPRINTF is undefined.
5417 typecmp was too pessimistic. Made it less so.
5419 Don't print space after address.
5420 If vtable points to a misc symbol (with 0 offset), print it,
5421 since that indicates the actual class of the object.
5422 Changed ype_print_derivation_info to use new inheritance
5423 scheme (without baseclasses vector).
5425 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5426 Also, changes needed because TYPE_BASECLASSES were removed.
5428 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5430 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5433 If there is no path set, and the symbols don't indicate what directory
5434 a file was compiled in, look in the current directory. But either
5435 a path or a known compilation directory will prevent this.
5438 Three independent bug fixes:
5439 * Remove the #if 0 block that breaks some stuff.
5440 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5441 adapt gdb to either SunOS 4.0.* or 4.1.
5442 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5445 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5448 (type_print) Demangle the name being printed.
5449 (type_print_base) Handle botched demangling without coredump (tiemann).
5452 (check_stub_method): Document routine.
5453 (tiemann) fix bug for no-arg functions
5454 Avoid clobbering beyond end of malloc'd storage.
5455 Terminate the argument list properly.
5457 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5459 * Changes merged by John Gilmore:
5462 In breakpoint_1, use new print_address_symbolic instead
5463 of find_pc_partial_function. (This forces use of assembler-level
5464 addresses, and avoids misleading non-mangled source-level names.)
5466 Generalize ansi argument such that -1 means skip arglist totally.
5467 Removed global variable print_ansi_qualifiers (which made
5468 code non-reentrant), in favor of extra explicit arguments
5469 to internal routines.
5471 Add new helper function print_address_symbolic.
5472 Use find_pc_misc_function instead of find_pc_partial_function
5473 (since we want assembler-level symbols here).
5475 Print unknown function as just "f (...)", not "f (...) (...)".
5476 Use new fputs_demangled explicitly.
5478 Fixed a typing violation (problem: value.h cannot be imported
5479 without renaming many variable in this file).
5480 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5481 decode_line_1: Moved forward some never-reached code.
5482 Made decode_line_2 skip function prologues correctly.
5484 fputs_filtered should not demangle by default.
5485 Add new fputs_demangled to demangle on demand..
5487 Change value_struct_elt to use value_primitive_field (using recursive
5488 utility function search_struct_field). This allows foo.bar to work
5489 for multiple inheritance (so far only for data fields).
5490 Change check_field in the same way (recursive helper function
5491 to support multiple inheritance).
5492 (Note: there are more of these problems that I haven't fixed.
5493 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5494 value_of_this: 'this' symbol name is now just "this", note "$this".
5496 Don't print static members.
5497 Avoid printing "members of <type>" if there are none.
5498 Simplified type_print_derivation_info by merging duplicate code.
5499 Remove useless blank lines in type_print_base (ptype command).
5501 Added declaration of new routine value_primitive_field.
5503 Added value_primitive_field which is generalized version of
5504 value_field that can handle multiple inheritance (non-zero offsets etc).
5505 Re-implemented value_field to call value_primitive_field.
5507 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5509 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5510 delete the whole environment. Karl Berry reported the bug.
5511 * source.c - fix openp to avoid //'s in filenames, which
5512 trigger an Emacs bug causing it to not be able to find files
5513 when running gdb in a window.
5514 * dbxread.c - zap the #if 0 that botches the add-file code.
5515 It seems to work a lot better without all the code commented out.

5532 to remove signle step breakpoint instructions.
5533 * main.c added "-epoch" flag and "int epoch_interface" to main.c

5538 format controls easier
5539 * wait.h added a couple of undef's because we were getting
5540 complaints about WSTOPSIG and WTERMSIG begin redefined.
