1 Fri Oct 4 16:47:32 1991 Roland H. Pesch (pesch at cygnus.com)
3 * doc/Makefile: make TEXINPUTS include . everywhere
5 Fri Oct 4 00:35:56 1991 John Gilmore (gnu at cygnus.com)
7 * coffread.c, dbxread.c, symfile.c, symmisc.c, symtab.h: Remove
8 vestiges of typevectors, which were for symsegs and are no longer
9 used. (From a question by Eliot Dresselhaus
10 <dresselh@RFT30.nas.nasa.gov>).
12 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
14 * dbxread.c, coffread.c: static-ize functions that were
15 gratuitiously external. (From Fred Fish.)
17 * c-exp.y: sym->class to SYMBOL_CLASS (sym).
19 * dbxread.c (dbx_lookup_type): Keep doubling size of typevector
20 until it is large enough.
22 * dbxread.c (read_type): Handle error case slightly better.
23 Make complaint message not C++-specific.
25 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
27 * infrun.c (wait_for_inferior): Fix step/next so that you only
28 stop at the beginning of a new line. This fixes various problems
29 with for loops, nested if-else's and switch statements.
31 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
33 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
34 between symtabs and psymtabs become ordinary error()s.
36 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
37 properly, making "end pc" correct in shared lib psymtabs.
38 (From Guy Harris <guy@auspex.com>.)
40 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
42 * dbxread.c: Enable, but soften, const_vol_complaint.
43 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
44 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
45 should be file-scope, not global.
46 (read_struct_type): Remove ancient multiple-inheritance warning.
47 (read_range_type): Check base type, complain & patch if undefined.
48 * stack.c (frame_info): Demangle the function name in `info stack'.
51 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
53 * eval.c (evaluate_subexp_for_address): Don't use
54 TYPE_POINTER_TYPE directly (it might be zero if this type has
55 never had a pointer created before); use lookup_pointer_type.
56 * symtab.c (lookup_method_type): Arguments were swapped in all
57 callers, so fix it here. I'm amazed this worked at all!
59 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
61 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
62 "bss" rather than "data" symbols, but which still conflict.
65 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
66 * core.c (core_files_info): Shorten output.
67 * exec.c (exec_files_info): Ditto.
68 (build_section_table): Ignore zero-length sections.
69 * language.c, printcmd.c: Lint.
70 * language.h (get_frame_language): Declare.
71 * saber.suppress: update.
72 * stack.c (find_relative_frame): Remove complex code that was
73 #if 0'd, stick with simple code. Lint.
74 * saber.suppress: Update a bit.
75 * symfile.c (add_symbol_file_command): Add "?" to question.
76 * utils.c (parse_escape): Avoid \a due to bdead compilers.
77 * value.h: Declare typedef_print.
79 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
82 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
83 (Reported by Mark Peek <mark@imagen.com>.)
85 * solib.c (solib_map_sections): Relocate all sections, even
86 though only the text section's size is tracked. Mark ld_text
87 for eventual elimination as we generalize to N sections.
89 * infrun.c (wait_for_inferior): Don't check if the PC is in a
90 call_dummy if we were stopped by a random signal that is being
91 passed to the program. This produced wierd results when calling
92 functions in the inferior and signals (e.g. SIGALRM) were in use.
94 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
96 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
97 Bugfix from Paul Eggert <eggert@twinsun.com>.
98 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
99 * valprint.c (print_floating): Print 9 digits for IEEE floats.

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

239 #if 0 out its uses, though, since they set a dead value.
240 * coffread.c (end_symtab): Use allocate_symtab.
241 (process_coff_symbol): #if 0'd for functions and params as above.
242 (read_enum_type): Recognize Modula-2 BOOLEAN.
243 * symtab.c (add_param_to_type): #if 0'd function to add a

255 * parse.c: New file with the common code remains of expread.y.
256 * parser-defs.h: New file with common declarations from expread.y.

281 * expression.h (enum exp_opcode): Add Modula-2 specific opcodes.
282 * expprint.c: Look up expression opcodes in language-specific

315 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
317 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
318 entries are enclosed herein. Not all of these changes
319 have been merged into the master GDB sources -- check the
320 ChangeLog above here for the merge log.
322 Mon Jun 3 17:05:45 EDT 1991
324 m2-exp.y Created. Tested outside of GDB for a few days. Proper
325 operators were added, C specific operators and tokens
326 removed. yylex() revamped to some extent. Still things
327 missing from the grammar, such as sets.
328 Tested for two weeks in GDB v3.5.
330 Tue Jun 11 17:23:48 EDT 1991
332 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
333 so they are built-in. Sort of a hack.
335 Fri Jun 14 12:53:51 EDT 1991
337 m2-exp.y Added range checking for numeric constants. Any numeric
338 constant is assumed to be of builtin type INTEGER unless:
339 (1) it is octal or hexadecimal, in which case it is a
340 CARDINAL; (2) it is too big to fit into an INTEGER, in
341 which case it is a CARDINAL.
342 eval.c Added simple range checking for +, -, and * on integers.
343 Doesn't work very well for *, since 6 * 1,000,000,000 =
344 1,705,032,704, which fails the simple test of result >=
345 first_operand, no matter in what order the operands are.
347 Tue Jun 18 14:11:30 EDT 1991
349 Broke the parser into parts, one containing the C grammar and the other
350 containing code to be shared by all of the grammars.
352 The following files no longer exist:
357 The following files were added:
359 c-exp.y (The C grammar)
360 m2-exp.y (The Modula-2 grammar)
361 parser-code.c (Code that is shared by the above grammar)
365 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
366 now necessary to use the Bison compiler compiler, since it
367 will generate function/variable prefixes other than yy.
369 Tue Jun 18 16:47:49 EDT 1991
371 symtab.[ch] Added the external variable working_lang, than holds the
372 value of the current working language.
373 Added the ennumerated type language_mode, with the values
374 language_auto and language_manual, the former meaning that
375 GDB sets working_lang as needed, and the latter meaning
376 that the value of working_lang is totally under user
378 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
379 REAL, BOOLEAN and CHAR. Also added the type codes
380 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
381 utils.c Added set_language_command and show_language_command to
382 implement the GDB support commands "set language" and
384 expression.h A number of identifiers were added to the type exp_opcode
385 to facilitate Modula-2 builtin functions, integer
386 division, and array indexing.
388 Wed Jun 19 13:25:58 EDT 1991
390 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
391 if the language specified by working_lang requires the use
392 of strict typing of expressions. Eventually, even this
393 will be able to be changed by the user.
394 Added the macro RANGE_CHECK, which evaluates to non-zero
395 if the language specified by working_lang requires the
396 checking of a value against the domain of its type.
397 Eventually, even this will be able to be changed by the
399 language.[ch] Predicates involving types (simple_type, ordered_type,
400 same_type, integral_type, numeric_type, character_type,
401 boolean_type, float_type) are added. These predicates are
402 based on the current value of working_lang, and are handy
405 Wed Jun 19 15:39:34 EDT 1991
407 eval.c Added the function type_array_rank which computes the rank
409 valarith.c Added the funtion value_bool, which when given a integer
410 value.h value (ie. struct value *) as an argument, it returns a
411 boolean value (ie. struct value *) true if that integer
412 is non-zero, and a boolean value false otherwise.
413 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
414 will print out properly.
416 Wed Jun 19 16:36:34 EDT 1991
418 valops.c Added the function value_capitalize, which returns it
419 value.h argument capitalized if its argument is a lowercase
420 letter, or the argument unchanged if its argument is not a
422 valarith.c Added the function range_check_p, which returns non-zero
423 value.h if its value argument is between the integral bounds upper
425 Added the function range_check_enum_p, which makes sure
426 that its value argument is a valid member of the domain of
428 Added the function range_check_range_p, which makes sure
429 its value argument lies between the upper and lower bounds
430 of its type argument, which must be a ranged type.
431 Added the function check_array_index, which range and type
432 checks an index of an array.
433 Added the function value_multi_subscript, which computes
434 array[idx1,idx2...idxN], given a value array and an array
435 of values representing indicies.
436 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
437 unpack_long to work with TYPE_CODE_BOOL and
440 Wed Jun 19 18:04:08 EDT 1991
442 symtab.c Stored pervasive types in a structure and make
443 lookup_pervasive_type() a lookup function that was based
444 on working_lang. If lookup_pervasive_type() returned
445 non-zero, then that value was returned (a fix, since
446 before it simply wouldn't return the pervasive type.)
447 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
448 non-zero if the language specified by working_lang means
449 "conversion" when it says "cast".
450 valops.c Added the function value_real_cast(), which performs a
451 value.h *cast*, not a *conversion*, which is what value_cast()
452 does when it can. In particular,
453 value_cast(<float_type>,4) = 4.0, while
454 value_real_cast(<float_type>,4) = some mess.
455 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
456 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
457 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
458 and MIN on integral types. *NOTE*: These are currently
459 hardcoded to work only if there are 8 bits per storage
461 eval.c Made logical functions call value_bool to return a
462 properly typed boolean value, based on working_lang.
464 Thu Jun 20 11:55:27 EDT 1991
466 valprint.c Types now print out in a Modula-2 fashion. This works for
467 the cases when the type is printed out step-by-step, that
468 is, it doesn't work when the name of a structured type
469 (which includes the keyword "struct", etc.) is simply
471 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
472 since type specifications in C and Modula-2 are very
473 different. The C printing of a type is very recursive,
474 whereas in Modula-2 it is generally very simple. C has
475 type prefixes and suffixes, which have no real analogue in
476 Modula-2. Maybe type_print() should call a language
477 specific type printer. This is also advantageous if we
478 compile GDB to exclude some of the languages. We'll just
479 leave those functions out.
481 Thu Jun 20 16:57:10 EDT 1991
483 dbxread.c When reading the complete symbol table in (via
484 psymtab_to_symtab()), the number and types of function
485 arguments are added to a function type. define_symbol()
486 calls add_param_to_type() to accomplish this.
487 Assumption: when we come across a function definition
488 (N_FUN symbol with an 'f' or 'F' in the name), its
489 arguments will appear before another function definition.
490 When a function is found, a pointer to its type is placed
491 in the global in_function_type. Changes that
492 add_param_to_type() makes are to this global.
493 valprint.c The type of a function now includes (for Modula-2) the
494 types of its parameters.
495 eval.c Type checking and a check for the proper number of
496 arguments is now done for function calls. Not sure of the
497 impact this has on C++ member function yet.
499 Thu Jun 20 19:58:48 EDT 1991
501 valprint.c Rewrote the type printer. Broke it into two language
502 specific parts, adding the functions type_print_m2() and
504 An unfortunate consequence is this: if you debugging a C
505 program in Modula-2 mode (why?), info types does not work
506 well with regular expressions, since the types are printed
507 out in Modula-2 terminology, but stored in C terminology.
508 language.[ch] Added the functions new_type_last(), type_keyword(), and
509 type_sep() to aid in the printing of typedefs.
510 symtab.c Made the printing of typedefs as language independent as
511 possible through calls to new_type_last(), type_keyword(),
514 Fri Jun 21 11:50:26 EDT 1991
516 dbxread.c Check all incoming ennumerated types. If it looks like
517 Modula-2's BOOLEAN type, then change the type_code of the
518 type to TYPE_CODE_BOOL so we can process it as a boolean
520 valprint.c Replaced some of the 0x%x with calls to sprintf and
521 hexformat() in val_print().
522 language.[ch] Added the function hex_to_string(), which converts its
523 integral argument to a hexadecimal number (format is
524 language based) and returns the result as a string.
526 Mon Jun 24 12:25:07 EDT 1991
528 valprint.c Some functions call type_print_1() directly, instead of
529 value.h using type_print(), so they can specify where (column) to
530 print things. Since type_print() takes care of language
531 dependence, that needs to be called first. Added a
532 parameter depth to type_print() (so it is now like
533 type_print_1). Changed type_print to type_print_at, and
534 made type_print a macro that passes a depth argument of
536 symmisc.c Changed all calls to type_print_1 to calls to
538 Makefile.dist Made it possible to build GDB for a specific set of
539 depend languages. Do this by passing a definition for the macro
540 LANGS to make. LANGS should be a string containing a
541 space-separated list of language names (ie. LANGS="c m2").
542 The default is to build all languages. Note that grammar
543 files must follow the naming convention of <lang>-exp.y.
544 gdb.lang This holds the current value of the LANGS macro. It is
545 examined every time make is called, and is updated if
547 eval.c Added #ifdef _LANG_<lang> to these files.
548 expread.c Still need to add them to dbxread.c and coffread.c.
556 Mon Jun 24 16:33:11 EDT 1991
558 language.[ch] Added the functions hexformat_pre() and
559 hex_to_string_pre(), which take a prefix argument to
560 include in the format string. Thus, hexformat_pre("08") will
561 return "0x08x" (if the working language is language_c).
562 Made hexformat() and hex_to_string() calls to the above
563 with "" as the prefix argument.
565 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
566 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
567 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
568 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
569 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
570 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
571 valprint.c, vax-pinsn.c
573 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
574 calls to hexformat() and hex_to_string(). Format strings without
575 the leading "0x" were ignored.
577 depend Updated to take the above into account.
580 Tue Jun 25 15:27:18 EDT 1991
582 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
583 and type_check_t to keep track of the current state of
584 range and type checking.
585 main.c Added the variables range_mode, range_check, type_mode,
586 and type_check to record the current state of range and
587 type checking. Added initialization code to main().
588 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
592 Tue Jun 25 17:57:08 EDT 1991
594 dbxread.c process_one_symbol() updates the variable (enum language)
595 source_lang based on the extension of the filename
596 contained in the N_SO sybmol that started this symtab.
597 When end_symtab() is called, the value of source_lang is
598 put into the language field.
599 stack.c select_frame() sets working_lang (and possibly type_check
600 and range_check) to the language field of the symtab
601 associated with the frame that is selected if working_mode
602 is language_auto. If working_mode is language_manual, a
603 warning is printed and working_lang is not set.
604 language.c Added the function set_type_range(), which sets the value of
605 type_check and range_check (if their modes call for
606 automatic setting) based on the current value of
607 working_lang. A non-zero argument will cause the current
608 settings to be output.
611 Wed Jun 26 14:51:40 EDT 1991
613 eval.c Added range checks on assignment.
614 m2-exp.y Added the grammar for sets to the language. Currently,
615 these do not do anything except print an error message.
617 Wed Jun 26 17:01:04 EDT 1991
619 m2-exp.y Added the ability for parse_number() to parse negative
620 numbers. A global flag is set upon encountering a unary
621 minus. This was done to make, for example, 1 parse as a
622 CARDINAL, and not as an integer, per Wirth's examples in
623 Programming in Modula-2 ed.4.
624 valprint.c Added support for "set radix 2" by then setting
625 output_format to 't'.
626 eval.c Implemented range checking on subrange types. Added calls
627 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
628 Implemented MIN and MAX for ennumerated types. The
629 minimum value of an ennumerated type is defined by Wirth
630 as the first identifier, and the maximum as the last.
631 m2-exp.y Made octal numbers ending with "B" be characters and those
632 ending with "C" be numbers, per Wirth's book. (p. 34)
634 Thu Jun 27 14:11:52 EDT 1991
636 stack.c select_frame() now only sets working_lang, it does not
637 notify the user. If working_mode is language_manual, then
638 a warning is issued once.
639 main.c At the end of each call to execute_command(), working_lang
640 is checked against the local static (enum language)
641 current. If they differ and working_mode is
642 language_auto, the new settings of language, type and
643 range checking are printed out.
644 stack.c Modified frame_info() to include the language of the
645 current frame in the output of "info frame".
646 language.[ch] Added the function language_str() which returns the name
647 of the current language.
649 Fri Jun 28 15:33:14 EDT 1991
651 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
652 the language. INCL and DECL currently cause an error,
653 since sets are not implemented yet. INC and DEC are
654 implemented as PREINCREMENT/PREDECREMENT with one
655 argument, and as ASSIGN_MODIFY with two arguments.
656 eval.c Added type checking to the above cases.
657 value.h Added not_lval_constant to the lval_type ennumerated type.
658 not_lval_constant means that the value is a constant
659 value; that is 3 or 'a' or TRUE, not as in a constant
660 identifier. This is used to help coerce numbers such as 3
661 to either signed or unsigned numbers.
662 valops.c Added the function value_coerce_constants() which coerces
663 constant integers as following: if one is a constant and
664 the other is not, the constant's type is set to the type
665 of the other argument. If both are constants and one is
666 signed, the other is converted to a signed constant.
668 Sat Jun 29 17:26:29 EDT 1991
670 valarith.c Added a better range checker. It now checks range
671 (successfully) on integral operations [+-] (signed and
672 unsigned) for any C sized type. Still does not work well
674 int_in_size() returns an integer that is coerced to fit into
675 specified number of bytes.
677 Mon Jul 1 13:04:14 EDT 1991
679 language.[ch] Added the function binop_result_type(), which returns the
680 builtin (struct type *) type that would be the result of a
681 binop on the two values V1 and V2.
683 Wed Jul 3 19:22:53 EDT 1991
685 source.c Extended source_info() to include the source language in
686 the output from "info source".
688 Fri Jul 5 13:48:52 EDT 1991
690 utils.c Moved the support functions for the GDB set/show commands
691 dealing with language into language.c.
692 language.c Added the function language_info(), which displays info
693 about the current working language, type and range check
694 settings. Called via the GDB command "info language".
695 Added an initialization routine _initialize_language(),
696 that sets defaults for the language, type and range
697 variables and sets up the new GDB commands.
698 main.c Language setup moved to language.c.
701 Mon Jul 8 10:10:22 EDT 1991
703 valarith.c Debugged the range checker for arithmetic. Still does not
704 work for multiplication very well.
706 Mon Jul 8 12:40:37 EDT 1991
708 language.[ch] Added the function value_true() which returns non-zero if
709 its argument represents a boolean true value.
710 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
711 check the truth of an expression.
713 Thu Jul 11 12:51:34 EDT 1991
715 language.[ch] Added the predicate structured_type(), which returns
716 non-zero if the argument is a structured type.
717 Added the predicate pointer_type(), which returns non-zero
718 if the argument is a pointer type.
719 eval.c Added the ability to do addition and substraction on
720 pointers and integers. This case simply bypasses the
723 Thu Jul 11 14:41:42 EDT 1991
726 Added the symbol N_DEFD (0x4a) which is a definition
727 module dependency that is used by the GNU Modula-2
728 compiler and the linker. It is not important to GDB,
729 except that [dbx|coff|mips]read.c should ignore these
732 Fri Jul 12 16:07:00 EDT 1991
734 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
735 0 in val_print(). Also added statements to the else part
736 to coerce type (argument to val_print) to a pointer type
737 if it is an "array of unspecified length".
738 valops.c Added the function value_m2_string(), which returns a
739 (value) value which is a constant string, whose type is
740 (ARRAY [0..n] OF CHAR). The length field of the type
741 structure is set to zero, so it will be interpreted as an
742 "array of unspecified length".
743 stack.c Moved the language/frame mismatch check to
744 main.c:execute_command().
745 main.c The working language is recorded each time
746 execute_command() is executed. If working lang has
747 changed during its execution, then the new
748 language/type/range info is printed out for the user. If
749 the working language does not match the language of the
750 frame, a warning is issued.
752 Sat Jul 13 16:16:39 EDT 1991
754 eval.c Moved all the type-checking stuff for operators to
755 language.[ch] language.c. This is so we can keep language-specific
756 stuff (like for what type operators are defined) in
758 language.[ch] Added the function binop_type_check(), which checks to see
759 if its two (value) arguments are type-compatible with its
760 opcode argument. The opcode should represent an operation
761 involving an operator. Also added the macro function
762 unop_type_check, which calls binop_type_check with a
763 NULL second argument.
764 expprint.c Added Modula-2 operators to the op_print_tab, so info
765 expression.h break works correctly. Also added "op_string", which
766 returns the string corresponding to the (enum exp_opcode)
767 opcode that is its argument.
770 Sat Jul 13 18:26:18 EDT 1991
772 coffread.c Added code to record the type of function arguments with
773 each paricular function. Code is very similar to that
775 dbxread.c Moved add_param_to_type() to symtab.c
776 symtab.[ch] Added function add_param_to_type() from dbxread.c
778 *** NOTE: The above additions have not been tested.
780 Mon Jul 15 12:50:47 EDT 1991
782 langauge.[ch] Added the functions type_error and range_error, which work
783 like error() except if the type/range mode is set to
784 *_mode_warn, then they do not do a return_to_top_level(),
785 but merely print a warning.
786 Also changed [set|show]_[type|range]_command() to support
787 the new "warn" feature.
789 Thu Jul 18 17:50:54 EDT 1991
791 mipsread.c Added code to record the type of function arguments with
792 each particular function. Code is very similar to that
795 *** NOTE: The above additions have not been tested.
797 Fri Jul 19 11:19:10 EDT 1991
799 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
800 UMIN_OF_SIZE, which when given a size of a numeric type,
801 return the maximum and minimum value it can hold. UMAX...
802 and UMIN... return the result for unsigned types.
803 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
804 struct types. They call above macros.
805 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
806 avoid a name conlict with the above.
807 c-exp.y Added range checking on numeric constants in
808 parse_number() for completeness.
809 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
810 return 0 if working_lang is not language_c.
812 Thu Aug 8 14:17:22 EDT 1991
816 breakpoint.c Documentation strings of some commands changed to
817 eliminate the references to the C language where
820 Tue Aug 13 15:48:03 EDT 1991
822 m2-exp.y Added qualified identifiers to the grammar. The semantics
823 are slightly different from those of the GDB operator ::
825 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
826 type_exp, where type_exp is any valid type expression.
828 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
829 printcmd.c Modified ptype_command() so it actually parses the input
830 (necessary for type expressions with scope qualifiers).
831 Added the function ptype_eval() which expects an
832 expression composed of one OP_TYPE element.
833 *.[ch] Replaced all occurences of parse_c_expression with
835 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
837 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
839 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
841 Small fixes from Peter Schauer:
843 * infrun.c (child_attach): Lint.
844 * solib.c (find_solib): Handle shared libs version 2.
846 Small fixes from David Wood:
848 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
852 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
853 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
855 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
856 chars_per_line is at maximum (user typed `set width 0'). Fix
857 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
859 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
861 * coredep.c: include ptrace.h where necessary.
862 * mipsread.c(parse_lines): fix unsigned char problem that was
863 messing up line numbers on SGI's and possibly other MIPS based
865 * infrun.c (child_create_inferior): use better test to check
866 return val from setpgrp().
867 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
868 for sgi/irix support.
870 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
872 * mipsread.c (parse_symbol): Put non-static procedures
875 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
877 Patch together `text_start' and `text_end' for 29K port.
879 * exec.c (exec_command): If NEED_TEXT_START_END, define the
880 variables and set them based on the exec file.
881 * am29k-tdep.c: declare text_start.
882 * valops.c (call_function_by_hand): declare text_end.
884 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
885 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
886 because machines that do this will also have to know to
887 set NEED_TEXT_START_END. Besides, it was a redundant way to
889 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
890 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
893 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
895 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
897 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
898 Pass MUNCH_DEFINE to munch whenever we run it.
899 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
900 format string; use 0x%x instead.
901 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
902 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
903 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
904 * inflow.c: Handle `short' process group IDs.
905 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
906 and check for ptrace errors.
907 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
908 (coff_symfile_init): Initialize text_bfd_scnum.
909 (read_coff_symtab): Use it to find the text [and absolute?] sections.
910 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
911 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
912 Merge target arm case with other "easy" cases. Add target
913 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
914 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
916 * minimon.h, remote-adapt.c, remote-mm.c: Add.
917 * munch: Cope with RT/PC putting fns in data segment.
918 Restore ability to override `nm' by specifying MUNCH_NM.
919 * xconfig/rtbsd, xconfig/ultra3: New host systems.
920 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
921 and remote-adapt. Remove encapsulated coff #define's (the
922 support should go in BFD, and gdb shouldn't know or care).
923 * tconfig/a29k-kern: Same, but for remote kernel debugging.
924 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
925 * tm-29k.h: Update BADMAG (though it should go away).
926 Allow the register definitions to be overridden in another
927 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
928 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
929 DUMMY_SAVE_GR96, for handling kernel calling conventions
930 that use GR64+ rather than GR96+.
931 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
932 remote debugging of Ultra3 kernel. Includes tm-29k.h and
933 overrides various things.
935 * remote-mm.c (mm_attach, mm_wait): Handle attach like
936 child_attach does, making a clean stop in the newly attached
940 * coffread.c: Make coffread independent of any particular
941 variant of COFF. Avoid #include-ing any particular one except
942 internalcoff.h. BFD now passes key values for symbol reading
943 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
944 and the symbol masks and shifts); use them.
945 Remove obsolete end_of_text_addr.
947 * exec.c: Remove unused include files.
949 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
951 * Makefile.in (documentation targets): Pass $(M4).
952 Bugfix from eggert@twinsun.com (Paul Eggert).
954 * stack.c (down_silently_command): Check for stack existence.
956 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
958 * Makefile.in (VERSION): Update to 4.0.3.
960 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
962 * core.c (core_file_command): Print frame at coredump with
963 its level number, by calling print_stack_frame.
964 * frame.h: Add selected_frame_level, print_stack_frame.
965 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
966 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
967 Change print_sel_frame and print_selected_frame callers to
970 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
971 * symfile.c (free_named_symtabs): Ditto.
972 * main.c (main): wrap_here needs an arg.
973 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
974 (solib_add): Avoid noise.
975 (solib_create_inferior_hook): Lint.
976 (sharedlibrary_command): Move dont_repeat to here.
977 * utils.c (error): Call wrap_here to force buffered output.
979 Small patches from Peter Schauer:
981 * coffread.c (start_symtab): Free any existing line_vector before
983 (read_coff_symtab): Ditto for type_vector.
985 * source.c (lines_to_list): New variable, replacing function.
986 (all uses): Use as variable.
987 (_initialize_source): Add 'set listsize' and 'show listsize'.
988 * utils.c (lines_to_list): Remove function.
989 * stack.c (print_frame_info): Use as variable.
990 * defs.h (lines_to_list): Remove declaration.
992 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
994 * breakpoint.c (insert_breakpoints): Restore warning about
995 the program might be running in another process, but only for
996 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
997 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
999 * utils.c (error): if error_pre_print is set, print the string
1001 * main.c (main, print_gnu_advertisement, print_gdb_version):
1002 Reformat legalese so it always prints, but acts as an "I'm here"
1003 message while symbols are being read. If any errors occur,
1004 print a few newlines to set off the message and start it at the
1005 left margin. Remove mention of "help" command, and don't yak
1006 about symbol reading.
1007 (catch_errors): Error string is now printed first in case of
1009 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
1010 suggest the "help" command.
1012 * Makefile.in (VERSION): Set to 4.0.2.
1014 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
1016 * .gdbinit: Remove useless "rr" command. Set complaints
1017 to 1 for people debugging gdb.
1019 * breakpoint.c, remote-vx.c: Reword strings printed by
1020 catch_errors callers.
1022 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1024 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1025 (Fix from kenc@viewlogic.com.)
1027 Fix some infrastructure to be able to cope with host and target
1028 machines with different sized basic types (ints, ptrs, etc).
1029 (Idea from pierre@la.tce.com (Pierre Willard).)
1031 * values.c (value_from_longest): Rename from value_from_long.
1032 Handle pointer types as well as integers, so that targets with
1033 different pointer sizes from the host can be accomodated.
1034 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1035 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1036 uses of value_from_long to value_from_longest.
1037 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1038 the correct pointer type to value_from_long{est}.
1040 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1042 * remote-vx.c: Remove obsolete code for calling functions via
1043 vxworks kludge interface (it referenced value_from_long).
1045 * valops.c (value_string): Find malloc with lookup_misc_func, not
1048 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1050 Make writing to files work properly. (Fixes to BFD are also needed.)
1052 * core.c (core_open): Open file ourselves, read or r/w, depending on
1053 write_files. Use bfd_fdopenr.
1054 * gdbcore.h (write_files): New variable.
1055 * exec.c (write_files): Define variable, add set&show for it.
1056 (exec_file_command): Use write_files to open for read or r/write.
1058 Make shared library reading happen automatically. These changes
1059 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1061 * inferior.h (stop_soon_quietly): Add to exported variables.
1062 * infrun.c (child_create_inferior): call solib hook, if defined.
1063 (child_attach): call solib hook, if defined.
1064 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1065 (find_solib): Use lookup_misc_func rather than hand-rolled.
1066 (symbol_add_stub): New stub for catch_errors.
1067 (solib_add): Avoid output if !from_tty. Catch errors rather
1068 than just calling symbol_file_add and bombing.
1069 (solib_create_inferior_hook): Interface with the target process
1070 to let it read and alloc shared libs, then figure out what it did.
1072 * core.c (validate_files): Fix typo, soften warning.
1073 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1075 * utils.c (fputs_demangled): Avoid duplicate printing if
1076 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1078 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1079 (Fix from pierre@la.tce.com (Pierre Willard).)
1081 * main.c (catch_errors): Change argument to a char * from an int,
1082 since a char * can point to a struct full of glop, but an int
1083 is not guaranteed to be able to hold a pointer.
1084 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1085 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1086 * core.c (core_open, solib_add_stub): Adapt.
1087 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1089 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1091 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1092 by adding .NOEXPORT target.
1094 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1098 * Makefile.in (VERSION): Roll to 4.0.
1099 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1101 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1103 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1106 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1109 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1111 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1112 reflect above name change
1114 * WHATS.NEW: correct pointer to refcard.
1116 * doc/gdb.texinfo: update New Features, Installing
1118 * doc/gdbint.texinfo: add short description of configure +template
1120 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1122 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1124 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1126 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1127 tar file, add dependencies for referenced doc files.
1129 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1131 * coffread.c, symfile.c, stack.c: saberized.
1133 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1135 * doc/refcard.tex: permuted Essential Commands sec
1137 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1139 set/show symbol-reloading
1140 default set complaints 0
1142 RET-repeat disabled after prompted long displays
1143 processID (attach) interpretation of 2nd GDB cmdline arg
1145 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1147 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1148 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1149 breakpoint.c, main.c: lint.
1151 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1153 Install new configuration scheme for GDB and friends.
1155 * config.sub: Translate ordinary names to three-part names.
1156 * configure: Use three-part names internally.
1157 * configure.in: Translate three-part names to filenames.
1159 * README, WHATS.NEW: Update for gdb-4.0.
1160 * Makefile.in: Roll VERSION to 3.99.
1162 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1164 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1165 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1166 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1167 to single structures rather than arrays; when passing
1168 their address, use &. This avoids trouble with bdead compilers.
1169 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1170 instead. This avoids portability headaches.
1171 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1173 * source.c (open_source_file): Avoid ANSI const bdeath by
1174 skipping declaration and then casting result value.
1175 * tm-hp300bsd.h: Clarify comment.
1176 * utils.c (strstr): Result is const char *; ANSI bdeath.
1177 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1178 since system include file defines it differently from "defs.h",
1179 though the two are equivalent for our purposes.
1180 * tconfig/hp300bsd: Add m68k-tdep.o.
1182 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1184 * tconfig/sun*4: Remove warnings about system assembler.
1186 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1188 * mcheck.c: Avoid warning about undeclared abort fn.
1189 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1190 it causes recursive calls to error() when used in cleanups.
1191 To do so requires that we make it a function, so we do.
1192 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1193 * utils.c (do_cleanups): Remove the current cleanup from the
1194 chain *before* calling it, in case error() is called from it.
1195 The result won't be pretty, but won't be an infinite loop either.
1197 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1199 * dbxread.c (read_struct_type): Grok anon structs for C++.
1200 (vb_name, vptr_name): Null terminate these strings.
1202 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1204 Minor bug fixes from BSD Net2 gdb:
1206 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1207 returns 0, there is no previous frame.
1208 * breakpoint.c (commands_command): If !from_tty, don't call
1209 input_from_terminal_p().
1210 * dbxread.c (record_misc_function): Speed up slightly.
1211 (compare_psymbols): Ditto.
1212 * infcmd.c (do_registers_info): Take a second argument to
1213 determine whether to print float registers. "info registers"
1214 does not do so anymore. "info all-registers" does, now.
1215 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1217 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1218 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1222 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1223 executing_breakpoint_commands if we are interrupted by error.
1224 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1225 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1226 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1227 catch_errors() so we can setup the frame regardless of whether
1228 the shared libs work.
1229 * ieee-float.c (double_to_ieee_extended): Get exponent from
1230 right place in little-endian systems. From John Carey.
1232 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1234 * main.c: Remove unused terminating_signals and catch_termination().
1235 (long_options): Terminate with a zero element.
1236 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1237 (gdb_readline): Make call-compatible with readline.
1238 (init_signals): Improve comments re vfork vs. signal.
1240 * utils.c (prompt_for_continue): Use new gdb_readline().
1241 If we prompt for continuation, we don't let CR repeat the previous
1242 command, once we get back to a prompt. It's too easy to keep
1243 hitting CR, expecting "--more--" prompts, and have some long
1244 command start repeating on you.
1246 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1248 * blockframe.c (frameless_look_for_prologue): Speed up by
1249 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1250 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1251 Define two variants, one faster.
1252 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1253 and return zero, rather than giving an error.
1254 (setup_arbitrary_frame): Initialize the PC in the new frame.
1255 (skip_prologue): Add a second arg saying whether we're just
1256 checking for a frameless function or not.
1258 * core.c (core_open, core_close, core_xfer_memory): Move
1259 section table pointers and bfd* into the target_ops.
1260 (core_open): Allow errors in shared lib reading, etc.
1261 (core_files_info): Describe shared library sections.
1263 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1264 exec_files_info, set_section_command): Move section table
1265 pointers and bfd* into the target_ops.
1266 (add_to_section_table): Add BFD to section table.
1268 * target.c (target_xfer_memory, target_info): Pass target to
1269 xfer_memory and target_info functions.
1272 * gdbcore.h: Move struct section_table.
1273 * target.h: New home of struct section_table.
1275 * solib.c (solib_add): New argument is the target_ops whose
1276 section list is to be added to, if any. Reallocate the
1277 sections in that target to add any that come from shared libs.
1278 (throughout) so_sections renamed to sections.
1279 (solib_xfer_memory): Deleted.
1280 * tm-sunos.h (SOLIB_ADD): Add target argument.
1281 (SOLIB_XFER_MEMORY): Delete.
1283 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1284 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1285 from target_ops. It's the same on all targets. Add two section
1286 pointers to target_ops.
1288 * stack.c (find_relative_frame): Dump ancient algorithm for
1289 "down", just use handy "next" pointers.
1290 (frame_command): Don't error if there is no stack; let user
1293 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1294 modifies static state in the parent process; new_tty itself
1295 runs in the child and modifies the child's file descriptors
1296 to match the saved static state.
1297 * infrun.c (child_create_inferior): Call new_tty_prefork,
1300 * infptrace.c (child_xfer_memory): Add ignored target arg.
1301 * remote-eb.c (eb_xfer_inferior_memory): ''
1302 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1303 * remote-vx.c (vx_xfer_memory): ''
1304 * remote.c (remote_xfer_memory): ''. Rename from
1305 remote_xfer_inferior_memory.
1307 * main.c (main): Only try to attach "corefile" argument if
1308 it starts with a digit.
1310 * symfile.c (symbol_reloading): New "set/show" variable.
1311 (symbol_file_add): Shorten message about symbol reading.
1312 (add_symbol_file_command): Merge with add_syms_addr_command,
1313 since this should work on all targets now.
1314 (stop_whining): Default to zero, to shut up complaints
1315 about bad symbol tables on many systems.
1316 (free_named_symtabs): Just exit unless symbol_reloading.
1318 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1319 and add comment explaining shared library screw.
1321 * source.c: #if defined => #ifdef.
1323 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1325 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1327 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1329 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1330 (doc/Makefile knows how to make one for local config)
1332 * Makefile.in: use doc/Makefile for doc targets
1334 * doc/Makefile: GDB documentation now has its own Makefile
1335 doc/refcard.tex: renamed from "gdbrc.tex"
1336 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1337 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1340 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1342 * values.c (baseclass_addr): When reading target memory, use the
1343 length of the basetype, not the upper type. We've only malloc'd
1344 enough space for the basetype, leading to errors in free().
1346 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1347 ends up as a function specially, since we know the actual type of
1348 the pointed-to address. This (somewhat) fixes display of
1349 expressions that include misc_function_vector names. Try `cond 1
1350 !strcmp("a","b")' then `i b'.
1352 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1353 The child can be proceeded from inside wait_for_inferior in
1354 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1355 getting skipped in that case.
1357 * expprint.c (print_subexp): Use filtered output, since the
1358 subroutines we call use it, otherwise the output is horribly
1359 mangled, since output of wrappable stuff comes out late.
1361 * Makefile.in: Bump VERSION to 3.98.1
1363 * infrun.c (child_create_process): Use execlp to find the
1364 shell to exec our target program. This requires some fiddling
1365 with `environ' since there is no execlpe().
1367 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1369 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1370 Minor rearrangement of refcard permits two new make targets--
1371 gdbrc.dvi DVI output for refcard, using CM fonts
1372 gdbrc.ps PostScript refcard, using PS fonts
1374 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1378 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1379 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1381 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1383 * doc/gdb.texinfo: last changes for release.
1384 Minor typo and formatting fixes; incorporated most fixes remaining from
1385 filed mail commenting on earlier drafts.
1387 Added warnings: pipes don't work in run command;
1388 conditions are converse of assertions;
1389 step over fn without debug info goes to next fn;
1390 vars may have "wrong" values near fn entrance, exit
1392 Added example from Kingston on printing repeated nonadjacent values
1394 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1395 shell mode for signals
1397 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1398 doesn't sound so much like its parent "Stopping and Continuing"; also
1399 moved entries on continue to top of section, so they don't get lost.
1401 Improved installation directions in appendix, added manual formatting
1404 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1406 * configure.in: Remove xm.h and tm.h even if we aren't linking
1407 new ones, so "./configure sun4; ./configure none" does the right
1408 thing. Assume that alldeps.mak and depend are already built in
1409 srcdir, and avoid running "make" (particularly "make depend",
1410 which involves "gcc") from inside configure. Build Makefile
1411 directly rather than building Makefile.conf first.
1412 * configure: Regenerate with above changes.
1413 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1414 to 3.98. Revise gdb.tar.Z procedure to produce a file
1415 called gdb-$(VERSION).tar.Z but which unpacks into a
1416 directory called "gdb". Move non-source files out of
1417 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1418 (depend): Don't try to do "gcc expread.y".
1419 (expread.o): Update dependencies by hand.
1421 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1424 Fixed a variety of small typos that prevented info from formatting
1425 cleanly; altered too-long heading for GPL Appendix, as discussed
1426 w/RMS; Changed date on cover to July 91.
1428 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1431 (1) Applied some fixes due to comments from Larry Breed (easier ones
1432 through chapsec 5.2)
1433 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1434 it's broken in latest texinfo
1435 (3) Introduced *some* use of [] for optional arguments, where
1436 explanation is not simpler by listing cmd w arg and cmd w/out arg
1437 separately. Still not using @deffn.
1438 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1439 couple of headings are too long. Need patches to texinfo or revision
1442 * Partial update to README (which still needs work for this
1443 release!): (1) use of configure corrected for new script,
1444 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1446 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1448 * symtab.c (lookup_symbol): Don't complain right off about
1449 no debug symbols; use the misc function vector first.
1450 (list_symbols): Use misc function vector to find symbols
1451 that don't have debug info, and print them.
1452 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1453 PC range doesn't match symtab PC range, as it does on the
1454 MIPS because our symtab reading isn't perfect.
1456 * dbxread.c (dbx_symfile_read): Make warning about
1457 "no debug symbols" slightly nicer.
1459 * source.c (select_source_symtab): If "main" symbol exists,
1460 but decode_line_spec can't find line info, don't just return
1461 a zero; try other source symtabs or give an error.
1463 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1464 their low addresses first, then rip through fixing high addrs.
1466 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1467 <runene@ifi.uio.no>.
1468 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1470 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1472 * Minor, mostly mechanical, cleanup of doc subdir for clean
1473 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1474 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1476 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1478 Mostly MIPS and general symbol-reading fixups.
1480 * doc/gdbint.texinfo: Add documentation on symbol-reading
1483 * mipsread.c: Remove kludges around #include "ecoff.h".
1484 Remove redefinitions of a_magic, etc, no longer used.
1485 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1486 Fix global overview comments to match symfile.c protocol.
1487 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1488 (mipscoff_symfile_read): Eliminate unused code. Avoid
1489 sorting all the symtabs, when all we have read here is psymtabs.
1490 The symtabs are sorted as they are created anyway. Tell
1491 condense_misc_bunches whether we're mainline.
1492 (psymtab_to_symtab_1): Pass filename when recursing, to make
1493 stack trace more informative.
1494 (parse_partial_symbols): Assume cur_hdr as argument.
1495 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1496 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1497 the TYPE_NAME of char *, since that's done in symfile.c.
1498 (free_numargs, parse_symbol, add_symbol, add_block,
1499 shrink_linetable): Declare these fns void.
1500 (upgrade_type): Convert tree of if's to switch. Clean up
1501 bogus "off == 0" handling with a complaint. Avoid setting
1502 field bitpos and bitsize of array with lower and upper bounds.
1503 Check specified bitsize of elements against their actual type's
1504 bitsize, and complain if different. Complain about unknown
1506 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1507 (psymtab_to_symtab_1): Print names of subsidiary files that
1508 are being read in. FIXME, we read far too many files. This code
1509 is not the problem, the problem is in parse_fdr where the psymtabs
1511 (cross_ref): Result should indicate that we used one aux entry
1512 normally, or two if we encountered a "next" entry. This used
1513 to leave the caller pointing at the wrong aux entry.
1514 (add_symbol): If overflowed cur_block, reallocate it larger,
1515 chase all pointers to it, and complain(), rather than clobber memory.
1516 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1517 (new_field): Only allocate one field initially, not two.
1518 Pull ++ out of macro argument. Simplify.
1519 (_initialize_mipsread): Avoid initialization of importd
1520 global_psymbols and static_psymbols.
1522 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1523 to properly set pst->symtab; avoid searching for it.
1524 (symfile_fns): Improve comments, add a FIXME.
1525 * dbxread.c: Update comments to reflect symfile protocol.
1526 (read_ofile_symtab, end_symtab): Return the symtab.
1527 (psymtab_to_symtab_1): Set pst->symtab.
1529 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1530 whether we're mainline.
1532 * symfile.h (sym_fns): Remove unused sym_discard member.
1533 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1535 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1536 the environment variable is not.
1537 * infcmd.c (finish_command): Use filtered printfs.
1538 * cplus-dem.c: Add struct tags to a few unnamed structs.
1539 * valops.c (value_coerce_array): Improve comments.
1540 * valprint.c (type_print_varspec_suffix): Print array size only
1541 if greater than zero.
1542 * m88k-tdep.c: Shift some lines left by one space, that had
1543 apparently been trashed at some point.
1544 * TODO: More things to do, a few got done.
1546 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1548 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1549 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1551 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1552 * expread.y, findvar.c, symmisc.c: Ditto.
1553 * printcmd.c (address_info): Update printed forms of LOC_
1554 symbols. Elim LOC_EXTERNAL.
1555 (print_frame_args): Keep track of param stack offsets before
1556 re-looking up to find the local register param is kept in.
1558 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1559 Further integration of mipsread into gdb. Eliminate unused
1560 routines, duplicate declarations. Handle static symbols in
1561 psymtabs as well as external symbols. When reading symtabs,
1562 insert symbols into the correct block (global, static, or a local
1564 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1566 (mipscoff_symfile_read): Don't call select_source_symtab.
1567 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1568 rather than SYMBOL_VALUE.
1569 (parse_external): Comment clobbering of top_stack.
1570 (parse_partial_symbols): Update comments. Allocate and parse
1571 static symbols as well as external symbols. FIXME, enum values
1572 are not handled in this pass, but should be. Inline new_psymbol.
1573 Use SYMBOL_VALUE_ADDRESS.
1574 (psymtab_to_symtab_1): Read symbols into global static block
1575 by default (until enter some function's local block context).
1576 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1577 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1579 * source.c (select_source_symtab): Select a source symtab
1580 from either the symtabs or, failing that, the psymtabs.
1581 (list_command): Update error message.
1582 (forward_search_command, reverse_search_command): Use getc, not
1583 fgetc, for speed. FIXME, add comment about buffers that die if
1584 overrun by long line.
1586 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1587 by an entire word, which is not portable, if we have a 32-bit
1588 field. (Code in dbxread.c already turns such bitfields, if
1589 aligned, into ordinary ints, but fixing this will help for other
1590 symbol formats and for future changes.)
1591 * core.c (core_open): Handle ANSI const brain death.
1592 * utils.c (vprintf): Fix varargs typo.
1594 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1596 * findvar.c (find_var_value): Handle &function better.
1597 * TODO: Document work needed on &fn and &array.
1598 * printcmd.c (print_address_symbolic): New arg is the prefix
1599 to print if a name is printed.
1600 (print_address_demangle): Honor "set print address" now.
1601 Use new arg above to improve spacing of output.
1602 * valprint.c (val_print): When printing function pointers,
1603 print symbolic form too.
1604 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1606 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1608 * core.c (memory_error): Reword error msg to mislead less.
1610 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1612 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1613 parse_partial_symbols): Use newer BFD internals (external_filehdr
1614 and external_aouthdr), byte-swap the fields that we care about
1615 before using them, and make the file header data local to
1616 read_the_mips_symtab rather than global.
1618 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1620 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1621 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1623 * main.c (command_line_input): Flush stdout and stderr
1624 before every call to readline. This reportedly fixes a bug
1625 that comes up in Sys V running emacs-gdb and/or xxgdb,
1626 when stdin/out are pipes or sockets.
1628 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1630 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1631 Avoid declaring Makefile dependencies, because GNU Make stupidly
1632 tries to update it if we do.
1634 * coffread.c: Revise for minor changes to bfd internal coff
1637 * configure: If -template= is given a relative path, make it
1638 absolute before recurring in subdirectories.
1640 * configure, configure.in, Makefile.in: Install "configure" script
1641 as replacement for config.gdb.
1642 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1643 * README: Update for configure, mostly. FIXME.
1645 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1646 target config files that they are for the host. When the lines
1647 get copied into the Makefile, this makes it more obvious what's
1650 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1652 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1653 tabs, which end up in the disassembler output inadvertently.
1655 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1657 Make it compile cleanly in an ANSI GCC2 environment.
1659 * blockframe.c: <stdio.h>
1660 * cplus-dem.c: free takes a void *, ifdef __STDC__
1661 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1663 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1664 * stddef.h, stdlib.h: Remove these files.
1665 * symtab.c: Avoid declaring qsort, close.
1666 * symfile.c: Avoid declaring close.
1667 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1668 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1670 Assorted other changes.
1671 * dbxread.c: include "libaout.h", not "liba.out.h".
1672 * printcmd.c (print_frame_args): Set recurse properly for
1673 indentation of struct and array parameters.
1674 * valops.c (value_cast): Allow cast to void.
1675 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1676 single_step() in a target-independent fashion.
1677 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1678 set up to be ready to continue. This makes us target independent.
1679 * infptrace.c (child_resume): Remove call to single_step; now
1680 can single step a SPARC target of any kind.
1682 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1684 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1685 docn into separate sections---basically chapters, plus two loose
1686 pieces that can be configured to go in different places. This
1687 allows GNU m4 to preprocess the manual without coredumping.
1689 * Makefile.dist: tell TeX where to find texinfo.
1691 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1693 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1694 the new target "rdl-apps.texinfo" which captures the Makefile
1695 variable that records where to find the Readline libraries.
1697 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1699 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1700 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1701 * defs.h (const, volatile): Only define if not already defined.
1702 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1704 * README: Update for release 3.95.
1705 * config.gdb: Don't create readline dir in subdir builds.
1706 * main.c: Include with "..." form for non-system include files,
1707 so "gcc -MM" for "make depend" works.
1708 Include readline files with "...h" rather than <readline/...h>.
1709 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1711 * coffread.c: Undo minor damage done by Rich Pixley. Use
1712 different internal and external representations of COFF
1713 data structures. Use new BFD routines for swapping them in and
1715 * symfile.c (free_named_symtabs): Avoid freeing file names that
1716 are null or empty. Old i960 tools seem to produce files that
1717 claim to have empty names, causing each successive file read
1718 to blow away the previous one.
1719 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1720 Move deferred_stores to top of file, but don't separate its
1721 #define's from its variable. Add commentary.
1722 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1723 favor of keeping the (working) config.gdb. Move readline
1726 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1728 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1730 * infptrace.c (fetch_registers): no result, since now void.
1731 * tconfig/news: target depends on m68k-tdep too.
1733 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1735 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1738 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1739 applied various small fixes due to or inspired by RMS comments
1741 * doc/gdb.texinfo: finished using all RMS comments, save those for
1742 appendices on readline and cmd history (which are in other source
1745 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1747 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1748 chapter 9; (2) documented 'break' command's menu mode for
1749 overloaded names, in response to hgs problem report C++ p-31
1751 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1753 * doc/gdb.texinfo: (1) better introductory example; (2) more
1754 consistent use of @code, @samp, @file, @kbd throughout; small
1755 cleanups to first three nodes; (3) new "Contributors" node;
1756 (4) Appendix, Renamed Commands; (5) divert specialized startup
1757 instructions to "Targets" chapter for generic manuals, while
1758 leaving them up front for manuals specific to specialized
1759 environments; (6) apply fixes from RMS comments through chapter 4.
1761 * pretex.m4: modify explanatory text slightly (and redefine
1762 "regexp") to keep GNU m4 from complaining. (It still crashes
1763 later, but one step at a time...)
1765 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1767 * readline/readline.c (update_line): Avoid dereferencing a pointer
1768 before comparing it to its bounds. Saber caught this.
1769 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1770 and only set PC if tgetstr returned non-null. Saber caught this.
1772 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1774 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1775 stuff for config manual) here where it counts; updated
1776 to use new subdir structure (gdb/doc/).
1778 * Makefile: generated from above via
1782 * gdbint.texinfo: added instructions on generating gdb.info* files
1783 locally for release. These are ordinary info
1784 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1785 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1786 to generate these, so we distribute them already formatted.
1788 * gdb.texinfo: included full Info node and menu crud (as generated
1789 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1791 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1792 put in comments-for-future gdb.info target (one day makeinfo will
1795 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1797 * gdb.texinfo: Updated to include new or old undocumented
1798 commands, at least the following (perhaps some others I forgot to
1799 record): info f, info float, info path, info program, info s, info
1800 set, info source, info terminal, info types, info user, set/show
1802 Also covered all recent GDB command renames for v4.
1804 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1806 * mipsread.c: Rather than keeping count of how many symtabs
1807 and psymtabs we have, for sorting purposes, count them when
1808 we need to sort. This fixes bug in rereading of symbol tables.
1810 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1812 * infcmd.c: renamed "info path" to "show paths"
1813 * gdbrc.tex: documented above.

1823 Fix up "saber_gdb" to work again.
1824 * saber.suppress: Update.
1826 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1827 symtab.h, target.c, target.h: Lint.
1828 * core.c: setup and select frame after reading shared libs,
1829 else reading shared libs will clobber them. Lint.
1830 * utils.c (error): Force out any buffered wrap text.
1832 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1834 * remote.c: Remove decls of memory_insert_breakpoint
1835 and memory_remove_breakpoint, no longer used. (Suggestion of
1838 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1839 to make it easier to interface to "configure"'d libraries.
1841 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1843 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1844 aliases for set/show print.
1846 Thu May 2 11:22:02 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1900 * coffread.c [TDESC]: Move setting of debug_info from
1901 coff_symfile_read to find_linenos and make it work with BFD.
1903 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1905 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1907 * utils.c (strsave): Make arg const char* not char*.
1909 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1930 Mips bringup and general cleanup
1932 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1933 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1934 (This still doesn't seem to make MIPS bkpts work.)
1935 * mipsread.c: Remove dup "Reading symbol data..." msg.
1936 (symbol_file_command, add_file_command): Remove, obsol.
1937 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1938 Wrap output appropriately.

1940 selected_frame rather than target_has_stack or coredumping.
1941 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1942 enums appropriately.
1944 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1948 * cplus-dem.c: Include defs.h and param.h.
1949 Makefile.dist: Don't hack in the "param.h".
1950 param.h: Don't include defs.h.
1952 * expread.y: Use a union to deal with the fact that type_stack
1953 can have both ints and enum type_pieces in it.
1954 ({push,pop}_type_int): New functions.
1956 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1968 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1969 copying.awk, solib.c, inflow.c, symmisc.c
1970 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1971 Use {value_as,unpack}_pointer (added to values.c)
1972 not {value_as,unpack}_long on CORE_ADDR's.
1973 Use longest_to_int (added to defs.h) instead of cast to int.
1974 Remove from_tty arg to mod_path.
1975 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1976 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2450 be renamed to "set section xxx yyy" FIXME) which sets the
2451 base address of a section of the exec file, overriding the
2452 virtual address that BFD reports.
2454 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2456 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2457 load symbols at any address while examining an exec file.
2459 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2461 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2462 for printing the float info is host-dependent, not
2463 target-dependent. FIXME.
2464 * i386-pinsn.c: Move #includes to top, remove useless ones.
2465 * i386-tdep.c: Don't bother including <.../reg.h> since we
2466 don't use it (and it doesn't exist on host systems).
2468 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2469 Convert negative numbers properly.
2470 (ieee_test): Make numbers really random; fix format arg.
2472 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2473 * core.c (core_detach): Unpush core_ops, which might not be on
2474 top. We used to just pop the top, which broke things. Don't
2475 need dont_repeat() any more.
2476 (core_file_command): Psst! Don't repeat it.
2477 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2478 * expprint.c (print_subexp): Avoid switch fallthru on
2479 BINOP_ASSIGN_MODIFY, so we can print += and such.
2480 * frame.h: Fix typo.
2481 * inflow.c (kill_command): After killing inferior, print our
2482 current frame in the core file, if we have one.
2483 (generic_mourn_inferior): When inferior dies, either select
2484 the current frame (in the new target, e.g. core file), or
2485 set both the current and selected frames to NULL.
2487 Changes from Peter Schauer.
2489 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2491 * Make all file names fit in 14 characters (sigh and damn!):
2492 mv hp300hpux-xdep.c hp300ux-xdep.c
2493 mv symmetry-xdep.c symm-xdep.c
2494 mv symmetry-tdep.c symm-tdep.c
2495 mv convex-opcode.h convx-opcode.h
2496 mv tm-vxworks960.h tm-vx960.h
2497 mv tm-vxworks68.h tm-vx68.h
2498 mv Makefile.srcdir Makefile.sdir
2499 mv gdb-int.texinfo gdbint.texinfo
2500 mv remote-sa.m68k.shar rem-m68k.shar
2501 mv remote-multi.shar rem-multi.shar
2502 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2503 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2504 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2507 * command.c (user_info_1, user_info): New command for listing
2508 the user-defined commands.
2510 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2512 * dbxread.c (really_free_pendings): Clear file_symbols
2513 and global_symbols after freeing them; otherwise, running
2514 this function twice (if it appears twice on the cleanup
2515 chain), we try to free things twice.
2517 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2518 based on text_addr (the address of text in core), not on addr (the
2519 offset between text in the .o file and in core). This change
2520 is from Peter Schauer.
2522 * main.c: Define ALL_CLEANUPS as a cast of zero.
2523 (return_to_top_level): Use it.
2524 (main): Do all cleanups after each command run as part
2525 of the gdb startup sequence. Also do all cleanups before
2526 entering the command loop, and every time we exit the command
2527 loop and reenter. Before, the cleanups from the startup sequence
2528 were being left undone until the first error!
2529 (command_loop): Rename do_nothing cleanup to command_loop_marker
2530 so we can see it easily when examining the cleanup chain.
2531 (init_signals): Add another do_nothing for signal handling.
2532 (quit_command): Only try to kill target if it has execution.
2533 Problems in the target stack got us into a state where
2534 inferior_pid was nonzero but none of the targets had execution.
2535 In this state you couldn't exit gdb.
2537 * dbxread.c: Two changes from Peter Schauer.
2538 (echo_command): Fflush output after an echo command.
2539 (show_history): Pass all args to cmd_show_list.
2541 * utils.c (init_malloc): Call mtrace to turn on tracing
2542 if the environment variable MALLOC_TRACE is set to a file name.
2543 * mtrace.c: Add source file which provides a log of every malloc,
2544 free, and realloc to a trace file.
2545 * mtrace.awk: Add source file which analyzes the trace file.
2546 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2547 (VERSION): Roll to 3.94.3.
2549 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2550 (check_duplicates): Don't bother with watchpoints.
2551 (set_raw_breakpoint): Comment about danger of this routine.
2552 (watch_command): Parse and eval all args before calling
2555 * solib.c (find_solib): Avoid error in referencing memory to
2556 see if any more shared libraries have been added. This is
2557 particularly useful if the target has terminated. Bug reported
2560 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2561 in bringing up 3.94.2 on the Sun-3.
2563 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2564 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2565 expression (in scope) before reenabling watchpoint.
2566 * signame.c (init_sigs): Add missing declaration of i, fix
2567 sys_siglist declaration.
2568 * source.c (list_command): Fixed range computation to use
2570 * stack.c (backtrace_command): Do not allow command if target has
2571 no stack, print informative error message.
2572 * target.c (target_command): Do not write into command line
2573 because this fails if the target command is used in a user defined
2574 command. [This change was enhanced by gnu to support any-
2575 unique-prefix matching on target names.]
2576 * valops.c (value_struct_elt): Avoid infinite loop on an
2577 erroneous attempt to print the member of function (try p main.p).
2579 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2581 * expread.y (name_no_typename): Avoid reduce/reduce errors
2582 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2583 Since the GDB parser really doesn't use name_no_typename in a
2584 name-only context, the parser can't tell the diff between
2585 names and numbers here. Avoid allowing a name_no_typename
2586 to be a NAME_OR_*INT to resolve the conflict.
2588 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2590 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2592 * valprint.c (val_print_fields): bitfield printing didn't handle
2593 byte order. Indirect through a few more fns to cope.
2595 * values.c (modify_field): also cope with byte order.
2597 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2599 Cleanup for release 3.94.2:
2601 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2602 include files. Roll version to 3.94.2.
2604 * coffread.c (init_stringtab): Read length into unsigned char
2605 array before swapping; don't assume 32-bit longs.
2607 * target.c (target_info): Don't bother with get_sym_file, just use
2608 the symfile global variable.
2609 * symtab.h, symfile.c (get_sym_file): Delete it.
2611 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2612 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2613 (read_type): Replace one more error() with complain().
2615 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2617 * i960-tdep.c: Fix copyright attribution.
2619 * config.gdb: Quote all backquotes in doublequotes. You can
2620 quote me on that. BSD 4.4 shell found this one.
2622 * infptrace.c (throughout): The third argument to ptrace is an
2625 * infrun.c (wait_for_inferior): When program has terminated, we
2626 have to call target_terminal_ours before we pop that target off
2627 the stack (e.g. before a call to target_kill or
2628 target_mourn_inferior). This fixes problem where a program
2629 terminates, then GDB stops for (tty output) and you have to type
2630 "fg" to the shell to resume it. FIXME: This code for what to
2631 do after termination really should be in normal_stop instead.
2633 * gdbcore.h (read_memory_check): Change declaration; it changed
2636 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2637 4.4 prereleases, this avoids a bug in their sgtty compatability
2639 * remote.c: Use terminal.h rather than hand-rolling the same.
2641 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2642 * utils.c (strsave, strstr): Fix arg types.
2643 * valprint.c (val_print): lint
2645 MIPS symbol table support from Per Bothner:
2647 * symfile.c (symtab_fns): Remove initializer table that needs to
2648 be hacked for each new symbol file format supported.
2649 (add_symtab_fns): New function, chains symbol table
2650 handlers into the global list.
2651 (symfile_init): Search this list.
2652 * symfile.h: Add next pointer, declare add_symtab_fns.
2653 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2654 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2656 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2657 symbol *). Thus, we no longer need the hack to trash
2658 pst->filename. Good, since that hack confused code in symfile.c!
2660 (reorder_symtabs, destroy_all_symtabs): Removed static
2661 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2662 Instead, the latter now uses a temporary array (stack-allocated
2663 from an obstack, and then freed).
2665 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2666 haven't been set in the outermost stBlock of a procedure. This was
2667 a problem with f77 binaries on Ultrix 4.?.
2669 (new_symtab, new_symbol, new_type): Continue changing code to use
2670 obstacks more and otherwise conform to dbxread internal style.
2671 Made the free_code of symtabs be free_linetable (as in dbxread)
2672 instead of free_contents. This implies memory leaks when reading
2673 a new symbol table, until the conversion is finished. Did change
2674 (struct symbol) and (struct type) to be allocated on the
2675 symbol_obstack. Blocks and blockvectors are among the things
2678 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2679 tested much, but it solved one problem (reported by Meissner), and
2680 cleans up some other things. The problem happened when an
2681 included file contains actual code (functions) and not just
2682 definitions. The mips coff is a little inconvenient there, since
2683 it may cause a procedure to be mapped to the wrong psymtab.
2685 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2686 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2687 this will need work for the new core paradigm.
2689 Opcode patches from the net:
2691 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2692 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2693 missing altogether - they are added here. From Bruce Bauman.
2694 * mips-opcode.h: The low mask for C0 instructions was too small.
2695 From Garrett Lau. I modified the fix to check the entire 32-bit
2698 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2701 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2703 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2705 * dbxread.c (read_type): Pointer subtraction (value_sub in
2706 valarith.c) sometimes failed because the types of the
2707 pointers being subtracted were not identical.
2708 These differed because dbxread.c was allocating pointer types
2709 using dbx_alloc_type+smash_to_pointer_type instead of
2710 lookup_pointer_type. I failed to find a justification for the
2711 former, so I changed it to use the latter. Similarly, I
2712 replaced smash_to_function_type by lookup_function_type,
2713 and smash_to_reference_type by lookup_reference_type.
2715 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2716 _initialize_mipsread): corresponding changes.
2718 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2720 * source.c (mod_path): Do tilde_expand on each component of the path,
2721 rather than on the (list of) paths as a whole.
2722 (print_source_lines): Set first_line_listed in addition to
2723 current_source_symtab and current_source_line. If the source was
2724 not findable, after a "dir" command to fix the problem,
2725 a "list" would get the wrong lines.
2727 While I was there... (gnu):
2729 * dbxread.c (read_type): Change error to complaint.
2731 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2733 First attempt at detailed understanding of symbol table memory alloc.
2735 * dbxread.c (dbx_symfile_read): Free our string table if we
2736 aren't the mainline. Free the "info" struct since we're done with
2738 (init_psymbol_list): Free any previously allocated psymbol lists.
2739 (): FIXME: Should realloc-down the psymbol lists when done reading
2740 the main symbol file?
2742 * symmisc.c (free_symtab): Free fullname field too.
2744 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2745 (REGISTER_ADDR): Make result type unsigned int.
2747 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2748 define REGEX must also define REGEX1 (its dependency).
2750 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2752 * tconfig/i960: No longer works, points you at vxworks960 or
2755 * xgdb.c, XGDB-README: Remove file. Users can get the much
2757 * Makefile.dist: Remove all trace of xgdb.
2759 * breakpoint.c (breakpoint_1): Pass demangle arg to
2760 print_address_symbolic.
2761 (clear_breakpoints): Remove unused function.
2762 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2763 (breakpoint_re_set): Use catch_errors to do them all anyway.
2765 * gdb-int.texinfo (Host versus Target): Add section on what is
2766 a "host" feature versus what is a "target" feature.
2768 * infcmd.c (path_command, path_info): Handle the PATH variable
2769 (object search path) as conveniently as the source search path.
2770 * environ.c (set_in_environ): Set some vars in GDB's environment,
2771 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2772 * source.c (mod_path): New function, from guts of
2773 directory_command, modifies a path. Used by path_command.
2774 (directory_command): Call it.
2775 * defs.h (strsave): Declare.
2777 * utils.c (sevenbit_strings): Add new printing option.
2778 (printchar): Use it.
2779 (strsave): Provide this handy helper routine.
2780 (set_width_command): Rename set_screen_width_command.
2781 (_initialize_utils): "set screen-width" => "set width";
2782 "set screen-height" => "set height"; add sevenbit-strings.
2784 * infcmd.c (do_registers_info): Print floating point registers
2785 in raw hex as well as float format, regardless of whether it is
2786 a "virtual" convertible register.
2787 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2788 regs as a double, just in case it's being used that way.
2789 * values.c (unpack_long): Comment on array/function coercion.
2790 (unpack_double): Argument is in target byte order now. For
2791 integer arguments, just call unpack_long and float the result.
2792 * m68k-tdep.c: include defs.h for "const" handling.
2793 * remote-nindy.c: Use ieee-float stuff.
2794 (nindy_fetch_registers): Unpack double regs to host double, then
2796 (nindy_store_registers): Pack extendeds to host double, flip
2797 around by misusing unpack_double, send as target double.
2799 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2800 zero, as when stopped at the first instruction of a process.
2802 * blockframe.c: Fix filename in comment (param.h => tm.h).
2803 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2804 * tm-68k.h: Fix typos.
2806 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2808 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2810 * coredep.c (fetch_core_registers): Pass end-address of register
2811 section to register_addr as expected. Don't call supply_register
2812 if we'd just pass it garbage.
2814 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2816 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2818 * target.c (push_target, target_info): Cast enums to int for < or
2821 * stack.c (print_frame_info): Identify source file & line
2822 even if we can't print it.
2824 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2826 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2828 Clean up IEEE floating point support.
2830 * ieee-float.h: New file.
2831 * ieee-float.c: Write real routines to convert between host
2832 doubles and various target IEEE extendeds.
2833 * m68k-xdep.c: Eliminate assembler code for extended floats.
2834 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2835 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2836 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2837 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2838 double_to_ieee_extended.
2839 * i960-tdep.c: Define ext_format_i960.
2840 * m68k-tdep.c: Define ext_format_68881.
2841 * sparc-tdep.c: Define ext_format_sparc, though unused.
2842 * Makefile.dist (HFILES): Add ieee-float.h.
2843 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2846 Obsolete the "coffstrip" program in favor of using BFD's strip.
2848 * nindy-share/coffstrip.c: Remove file.
2849 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2850 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2851 * tconfig/nindy960: Remove reference to coffstrip.o.
2853 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2855 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2857 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2858 * dbxread.c: Remove static symfile_bfd.
2859 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2861 * inftarg.c (child_detach): Pop the child_ops vector if the
2862 detach is successful.
2863 * remote-nindy.c (nindy_create_inferior): Don't push a new
2864 nindy_ops since nindy uses the same one for execution and memory
2866 * core.c (core_ops): Use child_attach and child_create_inferior
2867 rather than default attach and create_inferior functions.
2869 Handle floating point registers in core files.
2871 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2872 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2873 This version untested since BFD doesn't yet support sun3 core
2875 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2876 conventions. Fix comments and style. This version has not
2877 been compiled yet, since we have no HP inhouse.
2878 * core.c (get_core_registers): Look for two sections, ".reg"
2879 and ".reg2", and pass both to fetch_core_registers sequentially.
2881 Revise directory path yet again.
2883 * source.c (forget_cached_source_info): Not static any more.
2884 (init_source_path): New default source path is "$cdir:$cwd".
2885 (dir_command): Handle variable arguments ($cdir, $cwd).
2886 (source_info): Print "Compilation directory" rather than
2887 "Originally compiled in" to remind people of $cdir.
2888 (openp): If the path contains $cwd, use current directory.
2889 (open_source_file): If compilation directory is known, replace
2890 first $cdir in path with the compilation directory.
2891 (print_source_lines): Even if we can't print the lines, set the
2892 current symtab and line for future commands like "info source" or
2893 "breakpoint". Also, error message now contains the file name,
2894 line number, and file access error message.
2895 (_initialize_source): Fix help text to describe changes.
2896 * main.c (cd_command): Forget cached source info when we chdir.
2897 * utils.c (strstr): Add simple implementation.
2899 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2901 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2902 Byte-swap COFF symbol tables if necessary when reading them in.
2903 Use complain() to replace error message in one spot. Needs
2904 corresponding change in bfd/coff-code.h to make some symbol
2905 swapping routines non-static.
2907 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2909 Merge changes from Eirik Fuller, for UTek.
2911 * defs.h (errno): Add declaration.
2912 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2913 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2914 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2915 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2916 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2917 declarations of errno.
2919 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2921 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2922 <rpc/rpc.h> and <rpc/types.h>.
2924 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2926 * i960-tdep.c (examine_prologue): Add new argument limit,
2927 which stops the scan at the end of the prologue, or at the PC.
2928 This fixes a problem where it walks down into the code for the
2929 user's statements if that code looks like function prologues.
2930 Mark Fox and I have been bouncing this code back and forth, making
2931 small changes to it. Callers changed to match.
2933 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2935 Cleanup for gdb-3.94 release final:
2937 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2938 the .c files from vx-share and nindy-share, from the various
2939 macros, since they are not found via ALLDEPFILES.
2940 (SFILES): Add tm-i960.h.
2941 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2942 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2944 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2945 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2947 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2949 * am29k-tdep.c: Add contribution line.
2950 (examine_prologue): Cache information about function prologues in
2951 the misc-function-vector to avoid lots of references over the
2952 serial line while examining instructions.
2954 * core.c (core_close): New function made from cleanup_core.
2956 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2957 remote-vx.c, remote.c, target.c, target.h,
2958 Update target_ops vector to add attach, close, and load entries.
2959 Use add_syms_addr_command, not add_file_addr_command, for
2960 add_file. Break out close routine from existing code.
2962 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2963 they are in an obstack.
2964 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2966 (define_symbol): Add symbol type parameter; change callers;
2967 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2968 it to influence the symbol class on the i960.
2969 (define_symbol): Swap LOC_CONST's into target byte order.
2971 * exec.c (exec_close): New function.
2972 (exec_file_command): Call it.
2974 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2975 Fix byte order of frame pointer.
2976 (read_var_value): Result of 0 if var's value can't be found,
2977 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2978 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2979 (locate_var_value): Use read_var_value and use its lazy address
2980 as the location of the var's value. Lint.
2982 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2985 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2986 obsolete Intel versions in favor of vxgdb versions.
2987 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2988 code dealing with byte order of values, which Intel did in host byte
2989 order rather than gdb-4's target byte order.
2990 (i960_frame_chain_valid): Move to nindy-tdep.c.
2991 (examine_prologue, skip_prologue, frame_find_saved_regs,
2992 frame_args_address, leafproc_return, saved_pc_after_call,
2993 pop_frame): Add vxgdb versions from Mark Fox.
2994 (examine_prologue, frame_struct_result_address): Add code
2995 to deal with the saved value of G13 (struct return address
2997 (frame_args_address): Modify Mark's version to prefer the
2998 saved value over the current value in the topmost frame.
2999 Cache result in the frame info to avoid performance hair in
3001 (print_fault): Add gdb960 code for printing faults.
3002 (_initialize_i960): Actually call check_host.
3004 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
3005 add stub routines. FIXME, these currently just return zero!
3007 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
3008 (attach_command): Call target_attach, not target_open, now.
3010 * infrun.c (normal_stop): Make global, not static, for vx_attach.
3011 (child_attach): Rename from child_open.
3012 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
3013 don't confuse it with a zero step_resume_break_address.
3015 * inftarg.c (child_detach): Eliminate inferior_pid test.
3016 (child_files_info): Clean up message a bit.
3017 (child_ops): Use child_attach, not child_open, to attach.
3019 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3020 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3021 findvar.c to here, since it depends on the contents of the
3022 shadow_contents of breakpoints, but keep if #if 0 since it is
3025 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3028 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3029 (ptype_command, display_command): Eliminate have_inferior_p and
3030 have_core_file_p in favor of target_has_stack or
3031 target_has_execution.
3032 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3033 code for actually finding the values of arguments, though we still
3034 keep track of the maximum stack offset for use in printing unnamed
3035 arguments. Handle missing FRAME_ARGS_ADDRESS.
3037 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3038 (struct nindy_regs): Define registers passed to/from nindy.
3039 (nindy_fetch_registers, nindy_store-registers): Translate between
3040 nindy and GDB formats for the registers.
3041 (dcache_init): Statically allocate the cache, since it was being
3042 allocated by a malloc that was never freed anyway.
3043 (nindy_create_inferior): Error, not core dump, if no exec file.
3044 (nindy_before_main_loop): Use target_load, not target_add_file.
3046 * remote-vx.c (net_load): Specify large timeout for load
3047 requests. Allow user to break out with INTERRUPT.
3048 (net_break): Remove useless code, clean up. Change callers.
3049 (parse-args, skip_white_space, find_white_space): Clean up arg
3050 parsing to cope with quoted strings.
3051 (net_wait, net_quit): Never call error, just return status.
3052 (vx_read_register, vx_write_register): Cleanup status checking.
3053 #ifdef the code based on which CPU we are using (960 or 68k),
3054 FIXME, this should be completely general but it isn't yet.
3055 (vx_xfer_memory, vx_resume): Cleanup status checking.
3056 (vx_run_files_info): Improve message.
3057 (vx_load_command): Renamed from vx_add_file_command. Allow load
3059 (net_ptrace): Remove unused routine.
3060 (vx_wait): Adopt code from vxgdb960 to cope with broken
3061 connections to target machine and prompt to disconnect. Remove
3062 debug printouts. Map some EVENT_'s to SIGnals.
3063 (add_symbol_stub, vx_open): Print names of object files we found,
3064 and "ok" if we read their symbols OK. Clarify output in general.
3065 (vx_attach, vx_detach, vx_kill): Add these commands.
3066 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3067 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3068 "info files" output, and create_inferior, since we already have
3071 * stack.c (frame_info): Replace Frame_unknown with 0.
3072 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3073 (return_command): Pop until the PC matches as well as the FP,
3074 so it works even if the FP is shared with another function,
3075 as in "frameless" or "leaf" procedures.
3077 * symfile.c (load_command): renamed from add_file_target_command.
3078 (add_syms_addr_command): renamed from add_file_addr_command.
3079 (add_syms_command): Stub to call target_add_syms.
3080 (_initialize_symfile): Change command names and descriptions,
3081 add-file => add-syms, and load from alias to its own command.
3083 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3084 maybe_kill_then_create_inferior): Default for attempts to start
3085 a process, if one is already running, is to ask about killing
3086 it and retry if yes.
3087 (upstack_create_inferior): #if-0 it, strata obsolete it.
3088 (push_target, unpush_target, pop_target): to_close() a target
3089 before unstacking it.
3090 (target_info): Renamed from target_files_info.
3091 (_initialize_targets): Rename "i files" as "i target", accessible
3094 * target.h: Improve comments about the target_ vectored routines.
3096 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3097 Convert commenting style to standard GNU style.
3098 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3099 (SKIP_PROLOGUE): No longer a no-op.
3100 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3101 (*_REGNUM): Sort register numbers.
3102 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3103 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3104 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3105 are now 10 byte extendeds, not 8 byte doubles.
3106 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3107 for nindy versus vxworks targets. FIXME, this should possibly go
3108 in the target vector.
3109 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3110 frame_saved_regs and arg pointer with each frame.
3111 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3112 (FRAME_ARGS_ADDRESS): Use cached result.
3113 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3114 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3115 (PRINT_RAMDON_SIGNAL): Call print_fault.
3116 (POP_FRAME): Now works.
3118 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3119 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3120 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3121 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3124 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3125 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3127 * valarith.c (value_subscripted_rvalue): Avoid handling
3128 floats and doubles specially; it gave alignment errors. Lint.
3130 * valops.c (value_of_variable, value_of_this): Error if unknown
3133 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3134 to avoid alignment problems.
3135 (value_print): Handle unknown value address.
3136 (cplus_val_print): Two args are ignored; remove them. Change caller.
3137 (val_print): Use unpack_long rather than pointer-deref.
3140 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3141 to avoid alignment problems.
3142 (value_being_returned): Error if return value unknown.
3143 (set_return_value): Add bogosity warning, FIXME. *
3145 * TODO: A woman's work is never done.
3147 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3148 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3149 Add ieee-float.o to OBS.
3150 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3151 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3152 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3154 Changes to generalize the VxWorks RPC protocol slightly, to handle
3155 i960 as well as 68000.
3157 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3158 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3159 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3160 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3161 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3162 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3163 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3164 so they will move in target byte order rather than network
3165 byte order (happens to be the same).
3167 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3169 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3171 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3174 Add contribution lines to various files, showing where they
3177 * breakpoint.c (break_insn, check_break_insn_size,
3178 read_memory_nobpt): Remove to mem-break.c.
3180 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3183 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3184 entry has bad register number. This change is not
3185 tested in this release, FIXME.
3187 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3190 * value.h: Force value's contents field to be aligned to hold
3191 at least a double or a long long (if supported). This avoids
3192 doing bcopy's in and out of the contents field.
3194 (step_1): Avoid coredump under obscure circumstances when we
3197 * symtab.h (misc_info): Add field to misc function vector for
3198 any kind of cached information the target code desires. AMD
3199 29000 uses this to avoid repeating examine_function_prologue's.
3201 * coffread.c: Lint. Remove static symfile, read_section_header.
3202 core.c (have_core_file_p): Lint: remove.
3203 expprint.c (print_subexp): Lint.
3204 infptrace.c, valops.c, valprint.c: lint.
3206 Roll in changes from vxgdb-5.0.1:
3208 * symtab.h: Comment byte order of each address class. Add
3209 LOC_LOCAL_ARG for frame-relative args (960).
3210 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3211 symtab.c, symmisc.c: ditto.
3213 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3215 * remote.c (remote_resume): Error if resume with a signal.
3217 * symfile.c (prim_record_misc_function): Clear misc_info.
3218 (fill_in_vptr_fieldno): Check stub type of arg.
3220 * valops.c (value_cast): Avoid looking up names of types whose
3221 name we don't know, to prevent coredump. Sun CC produces typedef
3222 rtx and the name of *rtx is zero...
3224 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3226 Roll in changes from final AMD 29000 port (Tiemann).
3228 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3229 for ../include/a.out.encap.h. This might not work now that BFD
3230 is separately compiled. Instead, BFD support for encap will have
3231 to translate machine type 29k into the right COFF_MAGIC.
3233 * infcmd.c: Remove references to inferior_pid that aren't used
3234 in actual ptrace calls; use target_has_execution, etc.
3235 (have_inferior_p): Remove function.
3236 (program_info): Print target info rather than "process number";
3237 avoid gratuitous messages unless from_tty.
3238 (run_stack_dummy, finish_command): Set proceed_to_finish.
3239 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3240 main.c: Lint. Lose have_inferior_p().
3241 inferior.h (have_inferior_p): Remove, lint.
3242 (proceed_to_finish): Add flag to ask that all regs be saved
3243 by normal_stop, for the few commands that need it, speeding up
3244 serial I/O. Add comments to stop_registers.
3246 * remote-eb.c: Remove newline from breakpoint message we grep
3247 for. Never time out when running the user program.
3251 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3253 Roll in changes from vxgdb-5.0.1:
3255 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3256 symbol in its raw form, we are processing an unlinked ".o" file.
3257 See if the target environment has assigned it an address, using
3258 target_lookup_symbol (VxWorks does), and enter it into the symtab
3261 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3262 68k versions for a simpler version that assumes zero FP at bottom.
3263 Fixes bug of truncated stack reports.
3265 * target.h (target_lookup_symbol): Define this routine's args
3266 and result, finally.
3268 * target.c (nosymbol): Default routine for target_lookup_symbol.
3269 (target_default): Default lookup_symbol and call_function too.
3270 (files_info): Only print has_all_memory warning if a non-dummy
3273 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3274 vx_convert_from_virtual): If target does not have floating point,
3275 zero register "values", and avoid doing cross-net conversions.
3276 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3277 (vx_open): Rearrange code that attaches to target and reads
3278 symbols for all loaded modules, to work if some of the modules
3279 are not accessible. Add symbol_stub() and add_symbol_stub()
3280 as callbacks from catch_errors(). Allow connect attempt to be
3281 interrupted painlessly with ^C (FIXME, there are still some bugs
3282 if the interrupt happens during symbol reading.). Print
3283 final message with puts_filtered, since symbol messages are
3288 * main.c (catch_errors): Only print errstring if non-null.
3289 (command_loop): Avoid an ioctl per command to test ISATTY.
3291 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3292 (vx_xfer_memory): Return correct result!
3293 (vx_files_info): Indicate whether target has float or not.
3294 (vx_lookup_symbol): Complain, not error, if target gone.
3295 (vx_open): Print "Connected" msg before disabling immediate-quit.
3296 [FIXME: lookup_symbol and vx_open changes need testing.]
3298 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3299 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3300 contributor lines and update copyrights to 1991.
3302 Changes from an attempted H-PUX host port:
3304 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3305 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3306 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3307 * remote-vx.c: include <sys/time.h> for HPUX.
3308 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3309 "core_file_command" routine to BFD regime. May not work yet.
3311 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3313 * xgdb.c: Replace X10 version with some VJ version.
3314 (FIXME: Its copyright assignment is not on record.)
3315 * xgdb.c: Update include files to X11R4 (Xaw crud).
3316 (xgdb_display_source, create_text_widget): fix call to
3317 get_filename_and_charpos. Rewack source window stuff for X11R4
3318 (gleaned from include files, and "nm's" of binary libraries, since
3319 I had no doc available).
3320 (append_selection, append_selection_word): Disable with FIXME
3321 since R4 changed interface here.
3322 (create_buttons): Add back the old set of buttons.
3323 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3325 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3326 Roll VERSION to 3.94 (not yet final though).
3328 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3330 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3331 obstack_int_grow, obstack_int_grow_fast): Eliminate
3332 cast on left of assignment, which gives MIPS cc fits and is
3335 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3336 F_ALIAS. Use printf, not fprintf, when not passing a file
3338 (compare_opcodes): Check that identical instructions have
3339 identical opcodes, complain otherwise.
3341 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3342 was reported by Roland McGrath.
3343 (unimp): Only match if exactly zero instruction. (Roland)
3344 (branches and traps): Generate all variations of these
3345 instructions with macros, based on a single call that defines
3346 each condition name and its binary representation.
3347 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3349 * valprint.c (val_print_fields): Take, and use, format parameter.
3350 This means that "p/x struct" again prints the elements in the
3351 desired format. Changed callers.
3353 * stack.c (frame_info): Use filtered output, and indicate wrap
3354 points. Remove kludgy formatting designed to avoid line wrap.
3356 * utils.c (wrap_here): If the line is already full (because
3357 we had printed a long indent or long wrapped string), do an
3358 immediate newline-and-indent.
3360 * m68k-pinsn.c (print_insn_arg): Bugfix from
3361 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3362 instruction is incorrectly disassembled as bkpt #8.
3364 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3365 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3366 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3367 and then will dump core (sometimes). I traced it back to an
3368 uninitialized symfile_name in psymtab_to_symtab.
3369 (const_vol_complaint): Add quotes to message.
3370 (define_symbol): Only believe line number if gcc_compiled.
3371 Avoid allocating symbol if we will not return it.
3373 Add target strata support so that newly established targets go
3374 into their right place in the target stack (e.g. a new exec file
3375 doesn't wipe out the ability to access the running process).
3377 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3378 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3379 and initialize it properly in all the targets.
3381 * target.h: Document strata. Change return type of push_target.
3383 * target.c (nomemory): new function for dummy memory access.
3384 (tcomplain): Rename complain, now also used in symfile.c.
3385 (push_target): Push targets within strata. New return value shows
3386 whether new target is on top of stack or not. Always keep dummy
3388 (target_files_info): Ignore dummy target.
3390 * core.c (core_open): Warn user, and skip accessing file, if the
3391 core target is not the topmost target in the stack.
3392 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3395 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3396 target_ops, it doesn't belong there since we have no regs there.
3397 Change name of target from machine => memory to clarify.
3399 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3401 * Freeze version 3.93 for release.
3403 * Makefile.dist: Handle vx-share and nindy-share subdirs
3404 properly when building gdb.tar.Z.
3406 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3407 printed in various places, so I could change just one copy.
3409 * dbxread.c, coffread.c: Change references to bfd->iostream
3410 to cast to FILE *, now that BFD avoids needing types defined
3411 in other header files.
3413 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3415 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3416 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3417 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3418 (actually gcc -Wall).
3420 * dbxread.c: Remove first_global_sym, last_global_sym, since
3421 they are never referenced.
3423 * defs.h (baud_rate): Declare.
3424 main.c: Define it, and add the -b option to set it.
3426 * gdb-int.texinfo: Add text on how to define a new host or target
3427 architecture, prompted by Per Bothner's questions about MIPS
3430 * gdb.texinfo: Document "complaints". Change doc of -q since
3431 gdb no longer prints the copyright and blurb if you specify a file
3432 name to be debugged (just like Emacs). Add doc for Nindy-specific
3433 command line flags for specifying target serial port and such.
3434 Update copyright to 1991.
3436 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3437 has taken over for us the job of ripping up executable files. The
3438 crud caused Per Bothner's port to not compile.
3440 * infrun.c (normal_stop): Avoid printing "Program exited
3441 normally" if we are in batch mode. This allows a GDB which
3442 executes a program on a target system, to behave like a Unix
3443 command (input from stdin, output to stdout, no extraneous
3446 * main.c (main): Allow additional machine-dependent command line
3447 options to be specified with the ADDITIONAL_OPTIONS,
3448 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3449 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3450 processing to occur just before the main loop with
3451 BEFORE_MAIN_LOOP_HOOK.
3452 (main): If a "core file" argument is specified, and it is not a
3453 core file, try it as a process ID to attach.
3454 (symbol_completion_function): Attempt to cope with
3455 "show screen-" TAB, not very successfully. This needs more work,
3457 (batch_file): New function, returns whether we are reading
3458 commands from an interactive tty on stdin, or from somewhere else.
3459 Called by normal_stop since it doesn't get from_tty passed down
3460 to it like many commands do.
3462 * remote-nindy.c: Handle command line options for nindy
3464 (nindy_before_main_loop): Prompt user for tty name if they
3465 don't specify it before getting to the interactive command loop.
3467 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3468 and -r command line options. Also add hook before main loop
3469 to make it easy to specify a tty.
3471 * TODO: More things to do, one done.
3473 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3475 * dbxread.c: Make complaint() calls pass pointer, not struct.
3476 Add complaints about badly formatted C++ type information
3477 (const/volatile indicator, and parse errors resulting in
3478 error_type). Fix C++ virtual member fn comment.
3479 (read_struct_type): Avoid bumping pointer if we got a parse
3480 error; this prevents our walking beyond the end of a string.
3481 Terminate loop on null char as well as semicolon.
3482 (process_one_symbol): Fix the LBRAC fix so that it uses the
3483 last previous SLINE, FUN, or SO record's PC address. C++ debug
3484 symbols did not have SLINE records in a useful order compared
3485 to the LBRAC records.
3486 (define_symbol): Handle "catch" records.
3488 * symtab.c (check_stub_type): Added new complain
3489 `stub_noname_complain' and added a consistency check to
3490 keep the debugger from crashing when finishing from an
3491 exception frame. A real fix will be needed later.
3493 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3495 * infcmd.c (attach_command): Make global.
3497 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3498 but make them easy to comment out. Perhaps later they should
3499 be enabled by what CPU you configure for? FIXME.
3500 (VERSION): Roll to 3.93.
3501 (pinsn.o): Remove rule for obsolete file.
3502 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3504 Run down a problem that manifested by printing the wrong function
3505 name in stack traces of read_ofile_symtab. Turned out that the
3506 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3507 the LBRAC symbol with an address in the *data* segment, which
3508 blew our binary search through the blocks.
3510 * dbxread.c: Use the complain() facility consistently to bitch
3511 about problems in the symbol file we are reading.
3512 (finish_block): Add code to check the nesting of the blocks;
3513 complain and Procrust them to fit if wrong.
3514 (make_blockvector): Check the order of the blocks, complain
3515 [but don't cope] if wrong.
3516 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3517 symbols to be sure their PC value is greater than the last SLINE
3518 (line number) symbol we've seen, complaining and adopting the
3519 SLINE PC value if wrong.
3521 * symfile.h (struct complaint, complaint_root, complain,
3522 clear_complaints): Add.
3523 * symfile.c (complain, complaint_root, clear_complaints): Add
3524 facility to deal with non-fatal complaints and to regularize their
3526 (symbol_file_add): Clear complaint counters to allow new complaints.
3527 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3529 * dbxread.c (dbx_symfile_read): Remember the address and size
3530 of the string table for the main symbol file, so we won't read it
3532 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3533 to avoid reading the string table yet again. Lint.
3534 (throughout): Improve filtered output, including word wrap.
3535 (read_range_type): Improve Bothner's fix to handle other types too.
3537 * utils.c: Improve line wrap implementation. Handle unlimited
3538 width by making chars_per_line unsigned.
3539 (puts_filtered): New, easy, function.
3541 * defs.h (puts_filtered): add.
3543 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3544 call the identical sort_symtab_syms() in symfile.c instead.
3546 * expread.y: Suggest the `file' command rather than `symbol-file'.
3548 * command.h (enum var_types): Add zinteger for seroable
3550 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3551 nested if's into a switch.
3553 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3554 we did not stop because of a breakpoint (it must have been for
3555 some other reason, like a "stepi"), so don't print anything.
3557 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3558 doesn't include <sys/types.h>, old SunOS's require it for
3561 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3563 A test port of gdb-3.92.6 to the Sony NEWS.
3566 Don't normally link in remote- or vx stuff.
3567 Some of it doesn't compile, and it wastes space for 99% of the users.
3568 Remove reference to no-longer-used HAVE_VPRINTF.
3569 Fixed BFD_DEP typo to BFD_DIR.
3571 Fix cast in arg to bfd_h_getlong.
3572 Make char *prefix be const.
3573 Fix how certain range types are mapped into builtin unsigned int types.
3575 Remove 2 #includes. They cause errors (on Sony, at least),
3576 and aren't needed (they wern't in earlier versions).
3578 print_address_symbolic should never demangle labels
3579 (since it prints *assembler-level* labels).
3581 [This was superseded by the change to printcmd below.]
3584 Add some "volatile" return types to avoid warnings.
3585 If MISSING_VPRINTF add vprintf function and not just macro
3586 (since vprintf is used in printcmd.c).
3588 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3589 (The latter isn't grokked by some PCC-based compilers.)
3591 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3593 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3594 * nindy-share/coffstrip.c
3595 Added some forward declarations (otherwise, gcc complains
3596 about implicit extern redefined as static).
3598 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3600 Changes inspired by Per Bothner:
3601 * printcmd.c (print_address_symbolic): Take additional parameter
3602 specifying whether to demangle.
3603 (print_address): Pass in asm_demangle to control demangling.
3604 (print_address_demangle): New fn, takes explicit arg to control
3606 * utils.c: Add new vars demangle and asm_demangle, and let them
3608 (fputs_demangled): If !demangle, just print the argument.
3609 (fprint_symbol): If !demangle, just print raw symbol.
3610 * valprint.c (val_print): Call print_address_demangle rather than
3611 print_address, to cause demangling to depend on the global
3612 rather than assembler-level demangling setting.
3613 * WHATS.NEW, gdb.texinfo: Document.
3615 * main.c (show_command): Show all settings if no arg.
3616 (initialize_main): Make "info set" the same as naked "show".
3617 * command.c (cmd_show_list): Handle prefix commands in the
3618 list, and print the name of the setting as well as its English
3619 description and value.
3621 Allow gdb functions to specify where a line should wrap if it
3622 exceeds the size of a terminal line. Use it to make the output
3624 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3625 of the right size when screen width changes.
3626 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3627 (wrap_here): New fn, indicates a point in the output where we
3628 should wrap the line rather than just letting it overflow at a
3630 (fputs_filtered): Implement wrapping.
3631 (n_spaces): New fn, returns a pointer to N spaces.
3632 (print_spaces_filtered): Use n_spaces.
3633 * defs.h (n_spaces): Declare.
3634 * stack.c (print_frame_info): Wrap with 4-space indent after
3635 fn name and before filename and line number.
3636 * printcmd.c (print_frame_args): Wrap with 4-space indent
3637 before each argument name is printed.
3638 * valprint.c (value_print): Wrap with no indentation before
3640 (val_print_fields): Wrap with indentation relative to nesting
3641 level before each field name.
3642 (val_print): Wrap with nesting indentation before array elements.
3643 * command.c (do_setshow_command): Avoid extra newlines,
3644 wrap with 4-space indent around values printed, end with period.
3645 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3647 * breakpoint.c (breakpoint_1): Implement addressprint for
3648 "info breakpoints" display. Change file name and line number
3649 format to " at file:nnn" rather than " (file line nnn)".
3650 * gdb.texinfo: Document.
3653 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3655 Frozen for gdb-3.92.6 release.
3657 README, WHATS.NEW: Update for 3.92.6 release.
3659 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3660 coffread.o from configs since it is now built by default.
3661 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3662 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3663 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3664 from configs since it is now built by default.
3666 Makefile.dist: Update for release 3.92.6. Handle files that
3667 have been moved to ../include, ../getopt, or ../bfd. Add
3668 saber.suppress and tests directory. Add config.status to
3669 the release (it will say "none").
3671 coredep.c: Minor formatting fixes.
3673 These changes were made in early December but only checked in now:
3674 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3675 nindy-share/nindy.c: lint
3676 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3677 register values coming back from the target; we store values
3678 in target byte order everywhere.
3680 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3682 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3684 * valprint.c (cplus_val_print, val_print_fields): New functions,
3685 which print C++ objects. They conspire to avoid printing a
3686 virtual base class more than once, following all the twists and
3687 turns of C++ virtual base rules.
3688 (val_print): Call the above rather than do it by hand.
3690 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3691 symbol file, not for added files like shared libs. This really
3692 needs to be generalized to a timestamp per file.
3694 * core.c (cleanup_core): Avoid coredump if no core file.
3696 * config.gdb: Accept -host or -target in place of +host or
3699 * coffread.c (find_linenos): Avoid desupported BFD interface
3700 to line numbers. We still read them manually rather than using
3701 BFD's "generic" features.
3703 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3705 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3707 * Makefile.dist: Eliminate use of $< in explicit targets.
3709 * readline/Makefile: Use $< rather than $*.c, which does not
3710 include the VPATH in GNU Make.
3712 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3713 copies of tconfig/i960, added for global configuration
3714 compatability. All i960 versions can read both coff and b.out.
3716 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3717 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3720 * TODO: Think of more things to do.
3722 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3724 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3725 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3726 64-bit float conversion.
3728 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3729 equivalent to sun?os4 so global config works.
3731 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3733 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3735 * main.c: Only declare linesize once; declare pagesize not at
3736 all, since it is never used.
3737 (main): Clear newly allocated line before it is used.
3739 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3741 Further stabilization for the Intel 960.
3743 * Makefile.dist: Parameterize the location of the "include"
3744 and "bfd" directories, as well as "getopt". Add symfile.c.
3745 Link in both dbxread and coffread. Fix up "make depend" to
3746 rewack the locations of include, bfd, and getopt in its output.
3748 * README: Document moving include files, improve some of
3751 * coffread.c: Move common code out to symfile.c. Change
3752 symbol_file_command style interface to use new *_symfile_init
3753 and *_symfile_read interface under BFD. Use BFD internal
3754 info to locate line table, symbols, etc.
3756 * core.c (core_fetch_registers): Rename to get_core_registers
3757 to avoid confusion with fetch_core_registers.
3758 (register_addr): Move to coredep.c, which is already machine
3759 dependent. This leaves core.c pretty clean of dependencies.
3761 * coredep.c (register_addr): Accept this routine from core.c.
3763 * dbxread.c: Move common code (with coffread.c, etc) into new
3764 symfile.c. Each psymtab now contains a pointer to the
3765 format-dependent function that knows how to read it in. Make
3767 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3768 (process_one_symbol): Add code to complain about a "compiler bug
3769 we muzzle here", if we actually see it.
3771 * eval.c (evaluate_subexp): Insert missing "break" statements
3772 in code that determines whether a variable is an lvalue in
3773 memory, register, or whatever. I detected this via a compiler
3774 bug in which it *almost* mashed out the whole switch statement.
3776 * gdb-int.texinfo: Add minor sections on configuring gdb for
3777 release, and about the README file.
3779 * infcmd.c (registers_info): Fix formatting somewhat. Still
3780 not as pretty as before, but it handles byte swapping.
3782 * remote-nindy.c: If data cache routines are interrupted while
3783 waiting for the remote end, be sure that any uninitialized cache
3784 blocks are on the free list, not on the valid list!
3786 * symfile.h: Flesh out this header file with all the various
3787 routines and variables that have been merged in from dbxread.c
3788 coffread.c, and symtab.c to symfile.c.
3790 * symfile.c: New file, containing code common to dbxread.c,
3791 coffread.c, and some code from symtab.c. All generic code for
3792 reading symbol files should be in here now.
3793 (unrecord_misc_function): Remove unused function.
3795 * symtab.h: Remove file-reading things to symfile.h.
3797 * symtab.c: Remove file-reading things to symfile.c.
3799 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3800 to decode i960 fault types.
3802 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3803 target.c: Change type of the "resume" function from int to void,
3804 since its result was never used.
3806 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3808 * main.c: Replace "stupid" with "caution"; you now "set caution
3811 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3813 * infcmd.c (do_registers_info): Call val_print to deal with the
3814 byte order of the registers being printed. FIXME, this makes
3815 the formatting of the output uglier.
3817 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3818 defined, call it for signals the debugger doesn't itself use.
3819 The i960 uses this for more detailed fault information.
3821 * remote.c (remote_open): If arg is null, print help rather than
3824 * sparc-xdep.c (register_valid): Avoid declaring size, since
3825 various modules will think of various sizes depending on the
3826 architecture of their tm-file. FIXME, we need protection against
3827 actually entering one of those modules, which would clobber
3828 storage if not for the target architecture compiled into gdb.
3830 * stack.c (up_command, down_command): Always print the frame
3832 (up_silently_command, down_silently_command): New commands
3835 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3837 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3838 more parameters than it used to.
3840 * findvar.c (registers): Increase slop to 256 bytes, which should
3841 protect us against even most RISC machines with large register
3843 (locate_var_value): Move declaration inside related ifdef.
3845 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3846 throughout, to avoid throwing away buffered input from the board.
3847 (nindy_wait): Supply_register takes addr_of_value, not value.
3848 (i960_print_fault): Renamed from i80960_fault.
3849 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3850 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3852 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3853 we can set the PC in the call to proceed(). Unpush nindy_ops
3854 before pushing it on top, to avoid message to user. Eliminate
3855 commentary from Unix machines that just misleads here.
3856 (reset_command): Fix error message to suggest target command.
3858 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3860 Release 3.92.5 as frozen.
3862 Stabilize the merged release...with help from lint, Saber C,
3865 Everywhere: Add include files needed to declare return types
3866 of functions called.
3868 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3870 * breakpoint.h: Add undeclared breakpoint functions, and some
3871 functions for display handling since I couldn't think of a better
3874 * breakpoint.c (insert_breakpoints): Make code for disabling
3875 shared library bkpts more likely to work. It's used when we
3876 rerun a program and stop before the shared library has been
3878 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3879 cast from pointer, so it squeezes through catch_errors.
3880 (bpstat_stop_status): Fix logic broken some time ago. We now
3881 always create a bpstat if the stop address matches a breakpoint,
3882 even if we don't stop there -- just like the old code used to do
3883 before I got my fingers into it (sigh).
3884 (breakpoint_1): Print "ignore count" after "stop only if"
3885 condition, since that's how it actually works.
3886 (mention): Handle watchpoints as well as breakpoints.
3887 (watch_command): use set_raw_breakpoint and mention to do most
3888 of the work (and initialize all the fields!). Only pass one
3889 arg to parse_c_expression, since that's all it takes.
3891 * command.c (not_just_help_class_command): Rename arg to args
3892 since we ignore "unused argument" warnings on vars named "args".
3893 inflow.c (child_terminal_info): ditto.
3894 infptrace.c (kill_inferior): ditto
3895 main.c (catch_errors, version_info, quit_command, pwd_command,
3896 source_command, dump_me_command, editing_info,
3897 set_history_size_command, set_history, show_history,
3899 stack.c (locals_info): ditto
3900 target.c (target_files_info): ditto
3901 valprint.c (set_input_radix, set_output_radix): ditto
3903 * core.c: Remove old variables for handling core and exec file
3904 sections (data_start, data_end, stack_start, stack_end,
3905 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3906 text_end, exec_data_start, exec_data_end, text_offset,
3907 exec_data_offset, data_offset, stack_offset). They're
3908 superseded the more general build_section_table and
3910 (get_exec_file): Mention the `file' command.
3911 (read_memory_check): Rename to memory_error, and only call it
3912 in the case of an actual error.
3913 (read_memory, write_memory): call memory_error.
3914 (core_fetch_registers): Register section name is ".reg".
3916 coredep.c: Remove a bunch of crud now that all this file does
3917 is pull the registers out of a core file.
3918 (fetch_core_registers): Rewrite to actually work, I hope.
3920 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3921 Replace index() with strchr(). Remove all the pre-BFD macro
3922 definitions for accessing the symbol file.
3923 (struct dbx_symfile_info): Encapsulate the information that
3924 dbx_symfile_init needs to pass to dbx_symfile_read in this
3927 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3928 dbx_symfile_discard): Rearrange symbol file reading to divide
3929 the format-specific part from the format-independent part,
3930 leaving the format-independent part such as file name expansion
3931 and opening in symtab.c. This replaces
3932 partial_symbol_file_open and partial_symbol_file_read.
3933 Symbol_file_read, add_file, add_file_target_command,
3934 add_file_addr_command move to symtab.c. Pass an explicit
3935 "mainline" flag for when reading the main symbol table, rather
3936 than relying on the offset address to be zero or nonzero.
3938 (dbx_symfile_read): Don't allow void *'s to be printed as
3940 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3941 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3942 macro" debug version really work.
3943 (read_dbx_symtab): Remove unref'd parameter inclink.
3944 Avoid swapping N_SLINE symbols, for speed.
3945 Merge N_TEXT!N_EXT case with the other external symbol
3946 definitions' case. Add comments.
3947 (start_psymtab): Allocate the symfile name in the psymtab on
3948 the psymbol_obstack, rather than using the caller's storage.
3949 (end_psymtab): Only allocate a dependencies list if there are
3951 (psymtab_to_symtab_2): Use BFD when reopening file to read
3952 its symbols for real.
3953 (read_struct_type): Add FIXME comments where it needs work
3955 (read_huge_number): Add FIXME about overflows.
3956 (read_range_type): Add FIXME about comparing a long to 1<<32.
3958 * coffread.c: Minor changes to move things closer to the new
3959 regime with symtab.c and dbxread.c Major work is still needed
3962 * exec.c (exec_file_command): Remove old variables (see core.c
3964 (xfer_memory): If memory transfer is right at the end of a
3965 section, don't lose.
3967 * findvar.c (get_saved_register): If value is in a real
3968 register, LVAL is lval_register, not lval_memory.
3970 frame.h: Declare print_sel_frame and record_selected_frame.
3972 gdb-int.texinfo: New file, for GDB internals documentation.
3973 Very simple, unformatted doc of cleanups is there for now.
3975 gdbcore.h: Remove obsolete variables that described a.out
3976 section addresses and offsets. (See core.c above.)
3977 Declare fetch_core_registers and registers_fetched.
3979 getopt.c: Declare char *alloca(); even on SPARC.
3981 infcmd.c (run_command): Call target_kill rather than
3983 (step_command, next_command, stepi_command, nexti_command):
3984 Declare from_tty parameter even though we don't use it.
3985 (run_stack_dummy): argument BUFFER is a char array, not
3986 a pointer to REGISTER_TYPE.
3987 (finish_command): using_struct_return needed a value *,
3988 not a struct symbol *.
3990 * infptrace.c (child_xfer_memory): To avoid dependency on
3991 where sections are in memory, try PT_WRITE_D and if that fails,
3992 try PT_WRITE_I. Most Unixes don't care which you use.
3994 * infrun.c (step_resume_break_shadow): Change to array to
3995 match other breakpoint shadow storage.
3996 (clear_proceed_status): Pass address of bpstat to
3997 bpstat_clear, not the bpstat itself.
3998 (child_create_inferior): FIXME comment about if the child
4000 (start_inferior): Remove old function.
4001 (child_open): Use target_kill rather than kill_inferior.
4002 (wait_for_inferior): Ditto.
4003 (insert_step_breakpoint, remote_step_breakpoint): Use
4004 new step_resume_break_shadow.
4006 * inftarg.c (child_wait): If all child processes die,
4007 pretend that the one being waited for exited with signal 42.
4009 * main.c (command_line_input): When scanning for comments,
4010 don't coredump on unclosed quotes.
4011 (quit_command): Use target_kill rther than kill_inferior.
4012 (_initialize_main): Rename class_user from "user" to
4015 * printcmd.c (print_command_1): Initialize "fmt" if no format
4016 is specified by the user.
4017 (print_frame_args): Only add to args_printed if we are
4018 actually fetching args from the stack (avoiding undefined
4020 (_initialize_printcmd): Remove bogus \{ from string.
4022 * remote-eb.c (eb_open): Avoid coredump on no argument.
4024 * remote-nindy.c: Bring out of Intel environment into new
4025 target environment. Remove all conditional compilation on
4026 I80960. Massive hacking throughout.
4027 (nindy_xfer_inferior_memory): New routine stolen from
4029 (nindy_create_inferior): New routine pieced together, probably
4030 not quite working yet.
4031 (nindy_ops): New target_ops struct for nindy.
4033 * remote-vx.c: Use write_memory rather than target_write_memory
4034 to get error checking.
4035 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4037 (vx_create_inferior): Use target_terminal_ours...
4039 * signame.c (_initialize_signame): Always initialize, since
4040 we need the table for things other than psignal.
4042 * solib.c (solib_add): Use symbol_file_add, not add_file.
4043 (solib_address): Return boolean result rather than struct
4044 pointer which nobody else knows the type of.
4046 * sparc-tdep.c, valops.c: Use write_memory rather than
4047 target_write_memory, to get error checking.
4049 * stack.c (locals_info, catch_info, args_info,
4050 get_selected_block, frame_command, up_command): Use
4051 target_has_stack, rather than have_inferior_p or
4054 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4056 * symfile.h: New file, defining the interface between the
4057 generic and object-file-specific symbol reading code.
4059 * symtab.c: Move generic symbol-reading interface to symtab.c,
4060 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4061 table to map BFD targets to symbol-reading modules in GDB.
4062 Change index to strchr.
4063 (lookup_struct_elt_type): Use error() rather than hand-made
4064 simulations thereof.
4065 (lookup_partial_symbol): Speedup slightly when length == 0.
4066 (symbol_file_add): New function.
4067 (symbol_file_command): Call it.
4068 (symfile_open, symfile_init): New function.
4069 (add_file_target_command, add_file_addr_command): moved from
4072 * target.c (target_command): use target_kill.
4074 * target.h (target_files_info): Don't declare, never called
4077 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4078 files to determine stack end address.
4080 * valarith.c (value_x_binop, value_x_unop): Change error message
4081 to be more useful. Pass proper argument to value_struct_elt.
4083 * valops.c (value_assign): FIXME comment that long long
4084 bitfields will break here.
4086 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4087 Update `make saber_gdb' to work better.
4089 * TODO: A woman's work is never done.
4091 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4092 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4093 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4094 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4095 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4096 valops.c, valprint.c, exec.c: Lint.
4099 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4101 Continuing Intel 960 port merge of GDB.
4103 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4104 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4105 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4106 Wack over "make depend" so it handles files in subdirectories
4107 vx-share, nindy-share, bfd, and in the current directory.
4109 * blockframe.c (get_prev_frame_info): Remove fatal error
4110 if stack not defined.
4112 * core.c (core_open, core_detach): New functions that handle
4113 the old "core-file" command as "target core" and "detach" instead.
4114 (core_file_command): Call them.
4115 (core_xfer_memory): Use common routine xfer_memory.
4117 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4118 dbxread now uses bfd for everything but symbol reading itself.
4119 BFD internals are used to drag out the relevant file offsets.
4120 (partial_symbol_file_open): Change args all around for BFD.
4122 * symtab.c: Rename "value" to "val" everywhere, so we can
4124 (symbol_file_command): New command, moved from dbxread.c
4125 and coffread.c. It uses BFD to read the file, then vectors
4126 based on its type, to dbx or coff symbol readers.
4127 * symtab.h: Extern a few vars for symbol_file_command.
4129 * target.h: Breakpoint takes a char * save area, not a char **.
4131 * valprint.c (val_print): When unpacking bitfields, offset
4132 the address in gdb of the value, if it is declared with a shorter
4133 type. Remove the last "runtime kludge test" of host byte order.
4135 * utils.c: Remove old my_bfd_read routine.
4137 * stack.c (frame_info): Use target_has_stack. Print program counter
4138 register's actual name rather than "pc", since it's called the
4139 "ip" (instruction pointer) on the i960 (sigh).
4141 * target.c (target_command): Add command for selecting a target
4142 type and calling its open routine. This is used for initiating
4143 communication with a particular target, in a generic way.
4145 * tm-i960.h: Update for modern gdb. Remove semicolons from
4146 various macros. Handle reading struct return convention, and
4147 error-out attempts to return structs with the "return" command.
4148 Be sure gdb doesn't think we know how to call functions in the
4151 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4152 to i960_xxx in lower case.
4153 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4154 not being defined yet.
4156 * remote.c (remote_open): Call start_remote to initialize
4157 wait_for_inferior during open.
4158 (remote_xfer_inferior_memory): Return length written rather
4161 * remote-vx.c (target_command -> vx_open): Use new generic
4163 * remote-eb.c, inftarg.c, exec.c: ditto.
4165 * infrun.c: Fix comments.
4166 (attach_program -> child_open): Use new generic target command.
4167 (wait_for_inferior): Clear saved register values before target_wait,
4168 so target_wait can set some of them if convenient.
4170 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4171 Return success indicator, not void.
4172 (child_xfer_memory): Avoid fetching initial word if we'll
4173 overwrite it anyway.
4175 * infcmd.c (attach_command): Use new generic target open routine.
4176 (_initialize_infcmd): Update doc on attach and detach commands.
4177 (do_registers_info): Merge in a byte-order problem as a FIXME
4180 * findvar.c (find_saved_register): Avoid problem in current frame.
4181 (read_relative_register): Ditto.
4182 (write_register): Convert byte order on the way out.
4184 * exec.c (file_command): Add.
4185 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4186 (xfer_memory): Common function between core_xfer_memory and
4188 (exec_xfer_memory): Use it.
4190 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4192 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4193 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4194 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4196 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4198 Merge Intel 960 port of gdb, continuing...
4200 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4201 symbol_file_command): Pass from_tty arg to hush 'em up.
4203 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4204 Add magic numbers for 960 COFF format.
4206 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4208 Merge Intel 960 port of gdb, from Intel "1.2" release.
4210 CHANGE_LOG entries from their port, which was based on
4213 Thu Sep 6 11:02:22 PDT 1990
4214 Remove temp file if download is interrupted.
4216 Wed Aug 1 09:08:33 PDT 1990
4217 Now uses binary protocol to talk to NINDY.
4218 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4219 Times out after 5 seconds when trying to talk to NINDY.
4221 Tue May 29 12:54:49 PDT 1990
4222 Added variable baud rate (-b switch).
4223 Source code reorganization.
4225 Thu Apr 26 11:09:55 PDT 1990
4226 More cleanup of batch mode; specifically, execute "-s", "-e", and
4227 "-se" switches as soon as they are encountered on the invocation line.
4229 Fri Apr 20 13:47:15 PDT 1990
4232 Thu Apr 19 09:54:28 PDT 1990
4233 Add 'reset' command.
4235 Wed Apr 18 09:48:07 PDT 1990
4236 After opening remote tty, wait for 1 second to go by without input
4237 from it before trying to talk to NINDY (fixes problems with the
4238 Heurikon HK80/V960E).
4240 Mon Apr 4 16:33:05 PDT 1990
4241 Some output was not being suppressed in 'batch' mode.
4243 Thu Mar 22 15:31:11 PST 1990
4244 Ask user if old symbol table should be deleted when new file is
4247 Allow user to run a program downloaded before gdb960 was brought up.
4249 Correct "exec-file" help message for i80960 context.
4251 Correct bug in calculating user space address: could occasionally
4252 corrupt user program.
4254 Make sure to zero low-order bits in rip's because of bug in 960CA
4255 A-step part: could cause operation faults when "next"ing across
4258 Correct bug that made it impossible to get source line numbers for
4259 code loaded at addresses higher than 0x7fffffff.
4261 Wed Jan 10 12:43:22 PST 1990
4262 Open remote tty for exclusive use.
4264 Fri Jan 5 12:14:42 PST 1990
4265 Correct disassembly (CA manual was right after all):
4266 opcode for sysctl is 0x659
4268 Mon Oct 23 12:03:04 PDT 1989
4269 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4271 Mon Oct 16 14:15:09 PDT 1989
4272 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4274 Mon Oct 2 15:56:31 PDT 1989
4276 Added 960CA disassembly support.
4278 To simplify maintenance:
4279 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4281 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4282 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4283 - made disassembly interface identical to that in gdmp960.
4287 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4289 * target.h: Allow targets to stack. Add target_has_memory,
4290 _registers, etc. Restructure memory access and "info files"
4291 to walk the target stack.
4292 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4293 target.c: Change tables to match target.h.
4294 * inflow.c (child_mourn_inferior): pop child_ops.

4298 * remote-eb.c: New memory regime, new info files.
4299 * remote-vx.c: New memory regime, new info files. Now use
4300 separate targets for VxWorks attachment to machine, and
4301 actually running a process under VxWorks, since one has
4302 stack & execution & regs and the other doesn't.
4303 * remote.c: New memory regime, new info files.
4304 * sparc-xdep.c (fetch_core-registers): New memory regime.
4305 * target.c: New routines and support for stacked targets,
4306 new memory regime, new info files regime.

4310 including use of the new BFD (binary file) library.
4311 * gdbcore.h: Add struct section_table.
4312 * exec.c (build_section_table): Iterate all sections and
4313 record what gdb needs to know about them.

4320 * dbxread.c: Quick changes to make it compile with new BFD.
4321 * utils.c (error): Avoid using bfd_error in generic routines.
4323 * core.c (core_fetch_registers): Get from the ".regs" section of
4325 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4327 * inferior.h (attach_flag): Export.
4328 * infcmd.c (run_command): use new target_create_inferior.
4329 * infrun.c (child_create_inferior): Don't return result.

4335 since been deleted, such as temporary breakpoints.
4336 infcmd.c (program_info): ditto.
4338 * core.c (core_file_command): Display the frame where the core
4343 * remote-vx.c (target_command): Merge in target command from
4344 targ-vx.c. A few other cleanups.
4346 * TODO, Projects: Lots more stuff to do...
4348 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4350 Massive changes to wall off the remote-debugging interface
4351 behind a function vector. The port to handle VxWorks targets
4352 is also part of this.
4354 All files: Replace references to renamed functions,
4355 remove references to remote_debugging, remove references to
4356 have_include_file, have_core_file in favor of target_has_stack,
4357 target_has_memory, etc.
4359 * Modularize the breakpoint interface.
4360 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4361 a breakpoint instruction.
4362 breakpoint.c: struct breakpoint's shadow_contents now sized as
4364 (insert_breakpoints): Vector to target to install breakpoints.
4365 (remove_breakpoints): Vector to target here too.
4366 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4367 sparc-tdep.c (single_step): Use new breakpoint interface for
4368 the single-step breakpoints.
4369 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4370 New file, contains routines to insert and remove breakpoints by
4371 reading out the old contents and later replacing them. This is
4372 how ptrace breakpoints work, and many remote systems as well.
4374 * tm-vxworks68.h: New config file, overrides a few things for
4375 Wind River's preferences.
4377 * target.h: New file, for transfer vector used to talk to the
4378 inferior (child, attached, core, exec, remote, etc). All accesses
4379 to the thing being debugged should come through these vectors.
4380 target.c: New file, routines to handle transfer vector.
4381 (various files): Add transfer vectors XXX_ops for the various
4382 targets and pseudo-targets (core files, etc) we support.
4384 * breakpoint.c (bpstat_stop_status): Further explorations of
4385 watchpoints and why things don't work all the time.
4386 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4388 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4389 the local gdbinit if it doesn't already have it.
4391 * core.c (core_ops): add and install.
4392 Allow core debugging without exec file.
4394 * dbxread.c (free_and_init_header_files): Merge two fns.
4395 (end_symtab): Free named symbol table when a new version comes in.
4396 (read_dbx_symtab): Relocate all kinds of symbols with base
4397 address. First step toward handling different text, data, bss
4399 (add_file_addr_command): Renamed add_file_command.
4400 (add_file_command): Vector to remote handler.
4401 Add "load" as an alias for "add-file" command.
4403 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4404 non-returning functions.
4406 * exec.c: Add exec_ops, and push it as a target when an exec
4409 * infcmd.c (run_command): Pass executable file name and arg list
4410 separately when starting an inferior. Permit "run" when no exec
4411 file is specified, for VxWorks.
4412 (detach_command): Move to child_detach in inftarg.c.
4414 * inftarg.c: New file. Unix-child-specific routines, and the
4415 child_ops structure.
4417 * inferior.h (registers): Export "registers" as the way for
4418 target dependent register handlers to find gdb's local copy of
4419 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4420 since it is now used by places that want wait_for_inferior to
4421 handle the grunge but want to see every trap from the inferior.
4423 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4424 Eliminate remote_debugging hooks in terminal handling.
4426 * infrun.c: Replace start_inferior with child_create_inferior.
4427 Move all the hair of Unix shells and ptrace idiosyncracies into
4428 child_create_inferior, so remote handlers don't have to deal.
4429 Remove running_in_shell. Rename stop_after_attach to
4430 stop_soon_quietly, and use it in a few other places where we want
4431 to just call wait_for_inferior and get control back on the first
4432 trap. trap_expected now never takes a value > 1.
4433 (init_wait_for_inferior): Initialize static vars when a new
4436 main.c (gdbinit): Add new hook for .gdbinit file name, let
4437 it be overridden by config files as GDBINIT_FILENAME.
4438 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4439 Both of these are used for VxWorks gdb.
4441 mcheck.c: rename include file "gmalloc.c" to avoid problems
4442 with system include file "malloc.c".
4444 param-no-tm.h: New include file, same as param.h but does not
4445 include the default "tm.h" file. This is used in files where
4446 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4448 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4450 remote-vx.c: New file, VxWorks remote debugging support. Uses
4451 RPC routines that are shared with the target system, in directory
4454 remote.c: Vectorize remote interface.
4456 source.c: Globalize source_path, and make an alias "l" for "list"
4457 since we now have the "load" command.
4459 sparc-xdep.c: Use new param-no-tm.h.
4461 symmisc.c (free_named_symtab): Add new function from Wind River.
4462 However, ifdef it out for now while we think about what it should
4465 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4467 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4468 non-Unix-children handle this with their own code in the target
4471 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4472 source and target lists. Add vx-share to default list of include
4473 directories. Add new files to src and target lists: mem-break,
4474 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4475 ${srcdir} versions of munch and createtags are used.
4477 * valops.c (find_function_addr): Split out of call_function.
4478 (call_function_by_hand): Rename call_function; this function
4479 calls functions in the target by laboriously patching the target
4480 word-by-word with the right stack, args, regs, etc.
4483 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4485 Handle AMD 29000 a bit better.
4487 * remote-eb.c (readchar): Mask received char log to make it readable.
4488 (remote_start): Pass arguments down to executing program.
4489 Make startaddr unsigned.
4490 infrun.c (start_inferior): Accept args, pass them to
4492 infcmd.c (run_command): Pass args down to start_inferior.
4494 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4495 the target object file format.
4496 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4498 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4499 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4501 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4503 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4504 * TODO: We did a few things, we have more to do though.
4506 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4507 * inflow.c (inferior_died): Clear deferred stores.
4509 * Debug problems with dummy frames and calls to the inferior.
4510 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4511 * sparc-tdep.c (do_restore_insn): Simplify.
4512 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4513 (sparc_push_dummy_frame): Simplify and fix what we push.
4514 (sparc_pop_frame): Slightly more hair here, deciding whether
4515 we are restoring a saved PC or returning to a return address in %i7.
4516 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4518 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4519 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4520 * obstack.h (chunkfun): ditto.
4521 * defs.h (xmalloc, xrealloc): ditto
4523 * utils.c (quit): Grab the terminal from the child if necessary.
4525 * inflow.c (term_status_command): Rename to term_info, change
4528 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4529 (is_delayed_branch): Speed up.
4530 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4531 Still missing some float ops, and needs testing.
4533 * Support for input and output radixes other than base 10
4534 * defs.h (input_radix, output_radix): Declare.
4535 * expread.y (yyparse, parse_number): Handle changes of input
4536 radix, and ambiguous names-or-numbers in radixes >10.
4537 * printcmd.c (print_scalar_formatted): Print formatted hex
4538 numbers in varying column widths.
4539 * valprint.c (val_print): Use output_format to print scalar ints.
4540 (set_input_radix, set_output_radix, set_radix): Create.
4541 (set_output_radix): Set output_format from output_radix.
4542 (_initialize_valprint): add `set radix' but leave the others off.
4544 * main.c (execute_command): Let stupid questions be turned off.
4545 (_initialize_main): Handle "set stupidity", etc.
4547 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4548 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4550 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4552 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4553 bfd stuff is still screwed up, but with some manual work, it
4556 * breakpoint.c (bpstat_do_actions): Start over if a command
4557 proceeds the inferior, since the inferior will have stopped and
4558 will need to have its new stop-actions taken care of.
4560 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4561 compiler fits, simplify it.
4563 * gdb.texinfo (directory command): Doc new dir command.
4564 source.c (directory_command): "dir" now puts things on the front
4565 of the path, moves dups up front, and handles multiple names
4566 on the command line, inserting each one in order. It also
4567 blows away cached line and full_filename info.
4569 * stack.c (backtrace_command): Skip "more stack frames follow"
4572 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4573 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4574 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4575 The only odd one was Gould NP1, which had defined vprintf to
4578 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4579 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4580 variable, inspect_it.
4581 valprint.c (print_string, val_print): Use the global inspect_it
4582 to indicate whether to print in Epoch style or normal style.
4584 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4586 * printcmd.c (call_command): add an alias for the "print" command
4587 which runs expressions and doesn't print the result if void.
4588 (print_command_1): implement it.
4590 * command.c: Remove #if 0'd code. Initialize all the fields
4591 in add_cmd (). Rename do_nothing_command to
4592 not_just_help_class_command, and make it externally visible.
4593 command.h: add user_commands to struct.
4594 * main.c (define_command): Don't overload c->function with a char
4595 string as well as a function pointer.
4597 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4598 calling convention of value_struct_elt () that got dropped in
4601 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4602 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4604 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4606 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4607 until a good time (e.g. when we are about to run the child),
4608 saving ptrace calls.
4609 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4610 * tm-sparc.h: define DO_DEFERRED_STORES.
4612 * sparc-xdep.c (store_inferior_registers): when storing float
4613 registers, don't store stack regs too. When storing the SP,
4614 however, DO store the stack regs too. This fixes a bug in which
4615 the dummy frame is not recognized when a call_function finishes,
4616 because its frame pointer (in the stack regs) was never
4618 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4619 even though we don't know how to read them from an inferior.
4620 valops.c (call_function): Comment about storing SP.
4622 * infrun.c (save_inferior_status): Save away the original bpstat
4623 chain so it can be restored later. Install the copied version for
4624 use by whoever saved the status. It will be blow away by
4625 restore_inferior_status, and the original chain restored. This is
4626 important for people who have pointers into the original.
4628 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4629 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4630 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4633 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4635 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4636 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4637 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4639 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4641 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4642 Store the baseclasses in a type struct starting from array element
4643 0 rather than from the unusual array element 1.
4645 dbxread.c: the above.
4646 (virtual_context): Add
4647 Read new debug information about which virtual function table
4648 a virtual function is from, and store it in fn_field.fcontext.
4650 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4651 TYPE_FN_FIELD_STATIC_P.
4653 symtab.c: the above.
4654 valops.c: the above. Handle pointer casts of object *'s.
4655 (search_struct_method): Add.
4656 (value_struct_elt): First arg is now a pointer to a value, and is
4659 valprint.c: the above.
4660 values.c (value_virtual_fn_field): Add type arg. Handle
4661 offsetting to the proper object when calling virtual fns.
4663 (baseclass_addr): Add valuep arg.
4665 * README: Document the current state of BFD config (missing).
4666 * TODO, ChangeLog, Makefile.dist: Roll version.
4667 * WHATS.NEW: Add summary of changes since 3.5.
4669 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4671 * dbxread.c (read_struct_type): Clear bit vectors whenever
4673 symtab.c (B_CLRALL): define.
4675 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4676 using == rather than =. Huh... This fixes the dreaded problem
4677 wherein builtin_type_int becomes TYPE_CODE_FLT.
4679 * core.c (info_files): Show the inferior pid.
4681 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4682 already knows how to look in the source directory.
4684 * Remove psymtab hair from many places. Remove duplicated code
4685 for searching symbol tables. Hide psymtabs from most places.
4686 Make it fast to get from a psymtab to its symtab.
4688 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4689 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4690 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4691 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4692 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4693 new symtab completely. New psymtabs get symtab pointer
4694 initialized to zero. Remove MI warning printf.
4695 symtab.h: Comments. Add psymtab to symtab pointer.
4696 (PSYMTAB_TO_SYMTAB): New macro.
4697 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4698 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4700 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4702 (print_frame_info): Avoid special-casing symbols that have not yet
4705 * source.c (open_source_file): Quick path if we have already
4706 located the source file by its full name.
4708 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4709 find_pc_psymtab. When a name is found in the misc function
4710 vector, search the symbol table for its mangled name, not the
4711 name that the user typed.
4713 * bfd.h: Fix missing comment terminators, make #endifs match.
4715 * valarith.c (value_less): Handle unsigned int comparisons.
4716 Add FIXME about pointer compares, which assume host and target
4717 pointers are the same.
4719 * command.c (do_nothing_command): lint
4720 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4721 fix comments on debug symbol format for visibility. Actually set
4722 visibility of symbols.
4723 main.c (echo_command): lint; use <readline/history.h>.
4724 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4725 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4726 pointing past end of allocated memory; saber complains.
4727 obstack.h: Declare the external functions that we use.
4728 valarith.h: use <string.h>
4729 solib.c (solib_add): lint.
4731 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4733 * main.c (initialize_main): Default info_verbose to off, now that
4734 symbol reading is fast.
4735 (quit_command): Avoid clobbering exec_bfd while quitting.
4737 * Initial BFD (binary file diddling library) merger:
4738 coffread.c: Change AOUTHDR to struct exe_hdr.
4740 core.c: initialize initialized data at compile time.
4741 (core_file_command): Move from coredep.c, convert to bfd.
4742 (xfer_core_file): Convert to bfd.
4743 exec.c (exec_file_command): use bfd routines.
4745 mips-tdep.c: Remove exec_file_command and friends.
4748 * coredep.c: (fetch_core_registers) Convert core_file_command to
4749 fetch_core_registers.
4750 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4752 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4753 (my_bfd_read): More bogosity, which I don't think we call.
4754 (program_name): Remove this atrocity asap!
4756 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4759 values.c: allocate_repeat_value was not clearing the
4760 optimized_out field.
4761 (value_static_field): minor stylistic fix (wrong macro was used).
4762 valops.c (value_struct_elt_for_address): didn't work for C++
4765 * signame.c (_initialize_signame): Initialize signal names once.
4767 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4768 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4769 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4771 * remote-eb.c: Support user-settable baud rates on the serial port.
4773 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4775 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4777 * tconfig/sun3os4: Remove warning about native assembler,
4778 since it also occurs in the xconfig file.
4780 * findvar.c (registers): Allocate some slop after `registers'
4781 to prevent stray accesses from trashing the next variable.
4783 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4784 on the sun-3, by changing the #ifdef from `sun3' (which is not
4785 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4786 vars, which happened to follow `registers' in the executable.
4788 * readline/history.c (history_search): Heed gcc-2's advice
4789 and parenthesize && inside ||).
4791 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4792 tm-29k.c: Insert FSF copyright headers.
4794 * remote-eb.c: Better comments.
4796 * Makefile.dist: Update to 3.91.6.
4797 * TODO: note PREPARE_TO_STORE problem.
4799 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4801 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4803 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4805 * infrun.c (wait_for_inferior, at end): Don't set up
4806 prev_* if the inferior no longer exists.
4808 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4809 CANNOT_EXECUTE_STACK.
4810 valops.c (call_function): Use it.
4812 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4814 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4815 infrun.c (wait_for_inferior, 2 places): Use it.
4817 * values.c (value_being_returned): Only use
4818 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4820 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4821 right thing for remote-eb.c.
4823 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4824 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4826 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4827 (FRAME_FIND_SAVED_REGS).
4829 * findvar.c ({fetch,store}_registers): Check for
4830 REMOTE_{FETCH_STORE}_REGISTER macro.
4832 * findvar.c (get_saved_register): Add argument lval and
4833 change meaning of argument addr.
4834 findvar.c: Change calls to get_saved_register to reflect
4835 new calling convention.
4836 valops.c (value_assign): Use get_saved_register instead of
4837 find_saved_register.
4839 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4841 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4842 an (uninitialized) pointer to one. Use "&" when passing it
4845 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4847 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4850 * coffread.c (symbol_file_command): Put semicolon after
4852 Put safe_to_init_tdesc_context in #if defined (TDESC).
4853 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4854 coffread.c: #include <sys/stat.h>.
4855 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4856 Add missing ')' in check for "lc%" and friends. Remove
4858 Declare read_one_sym() at top of file.
4859 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4860 MC68WRMAGIC can have the same value without causing a duplicate
4863 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4865 * Allow a Makefile to be built without building the
4866 tm and xm file links that screw up builds in subdirectories.
4867 This is done with `config.gdb none', then you can do things
4868 like `make gdb.tar.Z'.
4869 * tconfig/none: Config file for no target system
4870 * xconfig/none: Config file for no host system
4871 * config.gdb: If no TM or XM files are called out by the
4872 host or target file, don't make links for them.
4874 * cplus-dem.c: Add documentation.
4876 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4877 simple error, so the user's gdb doesn't crash due to some object
4878 file problem (e.g. somebody is rebuilding the file out from under
4881 * printcmd.c (print_address_symbolic): demangle the symbol.
4883 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4884 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4885 (alldeps.mak): sort and uniq all results from this; duplicates
4886 hose gdb.tar.Z link building. Remove RCS files from
4887 tconfig and xconfig. Add config files for sun386. Add
4888 a few odd files to OTHERS and HFILES.
4890 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4892 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4893 Roll version number to 3.91.5. Make lint work in bindir.
4895 * README: Document cross-debugging and new file structure.
4897 * blockframe.c: Lint. Include "value.h" to declare read_register.
4898 (find_pc_partial_function): remove duplicate line.
4900 * command.h: Lint. Declare error_no_arg and dont_repeat.
4902 * tm-news.h: Remove inadvertently duplicated stuff.
4904 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4905 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4907 * config.gdb: Allow `config.gdb host target' form. Clean
4908 up previous change that printed bogus messages when you just said
4911 * core.c: #include "command.h" for lint.
4914 * main.c: Remove some casts of enums. Lint.
4921 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4923 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4924 read it from memory. This will allow us to save ptrace calls
4925 eventually. Changed caller single_step too.
4927 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4928 that we aren't going to use, saving many ptrace calls, especially
4929 when watchpointing or single stepping. Use some #define's for
4931 (store_inferior_registers): Ditto.
4932 (core_file_command): Use some #define's for constants.
4934 * tm-sparc.h: Add #define's for some register numbers, so we
4935 can eliminate the use of random constants in sparc-xdep.c.
4937 * stack.c (frame_command, print_frame_info, up_command,
4938 down_command) Remove frame_changed, since it
4939 causes a bug and doesn't seem to do anything useful. In some
4940 places it was used as a flag, in others as a stack level (?).
4942 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4943 default is to use the portable (vprintf) version rather than the
4945 * xm-news.h (MISSING_VPRINTF): Add.
4947 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4949 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4951 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4952 about linking debugged programs -Bstatic in the sun?os4 config
4953 files in tconfig and xconfig subdirectories.
4955 * main.c (main): Remove unreached exit(0) now that we exit
4958 * Create TODO file for online bug list. There are too many
4959 "little" bugs to keep track of on paper.
4961 * Change Projects file to refer to bug-gdb@cygnus.com
4962 rather than kingdon@ai.
4964 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4966 * Makefile.dist (VERSION): 3.91.4 now.
4968 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4969 (condense_misc_bunches): Add sanity check that misc_count is
4970 the same as the number of symbols in the bunch.
4972 * coffread.c: rename init_misc_bunches. Pass an argument
4973 to condense_misc_bunches (a zero).
4975 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4976 every time we are called; don't rely on our caller to do it.
4977 (add_file): Remove call to init_misc_bunches.
4979 * mipsread.c: Only warn, don't error, if unknown symbol types.
4980 This keeps an old gdb from falling on its face if it sees newly
4981 extended symbol info. Rename init_misc_bunches.
4983 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4985 * Merge in changes from Per Bothner for DECstations and other
4986 MIPS stuff. The rest is Bothner speaking:
4988 The next message is a merger of Alessando Forin's mips port with
4989 mine. I've tried to use my good if biased judgment to get
4990 the best of both. It *does* need testing.
4992 Some of the changes are general, *not* mips-specific.
4995 Didn't believe in little-endian bit order.
4996 There are still inconsistencies about whether flags
4997 like BITS_BIG_ENDIAN are integer (#if ...) or
4998 boolean (#ifdef ...). I tried to paper over them.
5000 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
5001 Moved some misc_function code that was common to
5002 {dbx,coff,mips}read.c to symtab.c.
5003 In the process, I think I cleaned things up a bit.
5004 At the same time, moved obsavestring and obconcat to symtab.c.
5007 Removed obsolete condense_addl_misc_bunches (use
5008 condense_misc_bunches(1) instead).
5011 Needed to include <sys/dir>, at least on DECstations.
5013 valops.c, mips-tdep.c, tm-mips.h:
5014 Added PUSH_ARGUMENTS macro to support funny argument-pushing
5015 conventions (when STACK_ALIGN is insufficient).
5016 Needed on mips, where doubles need 8-byte alignment,
5017 but ints only need 4.
5020 Removed cruft that was not being used.
5021 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5024 Print $ before register-names (I think that makes things a little
5026 Never print two instructions, even if one delays.
5027 Removed hex-disassemble set_cmd. (This is not mips-specific,
5028 so I think the argument is whether it is generally worthwhile or not.
5029 I'm inclined to think not, given how easy it is to
5030 convert between radixes in gdb.)
5033 This is basically Alessando's code.
5034 It doesn't use obstacks; I changed it to use obstacks
5035 in a few minor places where using malloc causes a
5036 memory leak. (Probably, more places could/should be changed.)
5037 I added record_misc_function where it was missing.
5038 In symbol_file_command and add_file_command, I tried
5039 to make the code consistent with more recent versions.
5040 Minor sylistic changes in parse_procedure.
5041 Make a .gdbinfo. psuedo-symbol point back to the real
5042 procedure symbol (using the isym field).
5045 This is basically from my port, but with a lot of details
5046 and a number of routines merged in from Alessando's version.
5047 I basically used my code "raw" backtrace (use heuristics
5048 from the actual code, rather than symbol table info) - though
5049 the idea is Alessandro's. I feel my code is a little cleaner
5050 here, particularly in being a little more flexible, such as being
5051 able to handle gcc-produced code (which it now can).
5052 It also doesn't do frame caching (which is not useful
5053 more recent gdb versions).
5054 I also used my code for push_/pop_dummy, more or less.
5055 I tried to incorporate AF's code for testing sigtramp
5056 while backtracing; I probably got it wrong.
5057 Added mips_print_register, which tries to scrunch as much
5058 information as possible on a screen...
5059 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5060 under mips-pinsn.c), I don't see anything mips-specific here,
5061 and I don't see it being all that useful anyway.
5064 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5065 Use more register names (rather than hard-cases numbers).
5067 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5069 * Hack up 3.90.11 changes:
5071 * Makefile.dist (depend): parameterize $(GCC).
5072 Add solib.c and solib.o.
5073 (readline): Fix vpath for both absolute or relative SRCDIR.
5075 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5076 Also, let the part I didn't understand at least compile so
5077 I can test the rest. FIXME.
5079 * dbxread.c: Fix thinko using strcmp.
5080 (init_psymbol_list): declare static.
5081 (partial_symbol_file_open): Comment cleanups better, avoid
5082 cleaning up the string table since the caller will do that.
5083 Move the stat for mod time into symbol_file_command, temporarily.
5084 (There should be a mod time for each symbol file, eventually,
5085 to control its rereading. FIXME.)
5087 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5088 SunOS, which gives error for shared libs otherwise. (From
5089 Schaefer, probably FIXME needs work for portability.)
5091 * solib.c: Move #include "param.h" to work.
5092 Lowercase all the Uppercase Letters In the Messages.
5093 (find_solib): Clean up inferior_so_name for debug printouts.
5094 Allow no argument, to mean all shared libraries.
5096 * symmisc.c: include param.h to get CLEAR_SOLIB.
5098 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5100 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5101 to 3.90.11. ChangeLog entries below are from this.
5103 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5107 * Makefile.dist (HFILES): Add tm-sunos.h.
5109 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5113 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5115 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5117 * sparc-opcode.h Added single-operand version of rett.
5119 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5121 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5122 Put parens around gcc_p in expansion.
5124 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5126 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5128 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5130 * Changes for Sun shared libraries:
5131 blockframe.c (find_pc_partial_function): If a non-text symbol
5132 is found, set *address = pc - FUNCTION_START_OFFSET.
5133 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5134 Disable breakpoints instead of giving an error.
5135 source.c (select_source_symtab): Initialize cs_pst.
5136 symmisc.c: Call CLEAR_SOLIB if defined.
5137 symtab.h: Make text{low,high} CORE_ADDR not int.
5138 (psymtab): New field addr.
5140 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5141 (record_misc_function): Give correct type for N_DATA symbols.
5142 (condense_misc_bunches): do "misc_function_count = j" regardless
5144 Take code which is shared between symbol_file_command and
5145 add_file_command and put it into partial_symbol_file_{open,read}.
5146 Split add_file_command into add_file_command and add_file.
5147 Make psymtab_to_symtab read in the string table if the file
5149 Two new parameters to read_dbx_symtab and start_psymtab.
5150 tm-sunos.h: New file.
5152 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5154 * infcmd.c: Change cont_command to continue_command and "cont"
5157 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5159 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5161 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5163 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5164 size 1,2,4,8 rather than size < 8.
5166 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5167 as necessary, not just once.
5169 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5171 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5173 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5175 * tm-news.h: Add CALL_DUMMY_*.
5177 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5179 * config.gdb: In list_host, list_target, use ${i}, not $i.
5181 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5183 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5185 * sparc-opcode.h: Change all store floating-point state register
5186 instructions to have the right match & lose fields.
5188 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5190 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5192 config.gdb: If srcdir != ., create readline directory and
5193 copy a makefile into it.
5195 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5196 consistency with POSIX.
5198 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5199 when we exit its exp_valid_block.
5201 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5203 * Makefile.dist: Bump version to 3.91.3.
5205 * Clean up handling of breakpoint commands (somewhat).
5206 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5208 inferior.h: Add breakpoint_proceeded to inferior status struct
5209 and globals; save it and restore it.
5210 (clear_breakpoint_commands): Cleanup, remove old #define.
5212 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5213 (save_inferior_status, restore_inferior_status): handle it also.
5214 (proceed): Remove earlier code that set breakpoint_proceeded.
5215 It is now set only in clear_proceed_status.
5216 (clear_proceed_status): Cleanup, use bpstat_clear rather
5217 than clear_breakpoint_commands. No callers need the stop_bpstat
5218 between clear_proceed_status and proceed.
5220 infcmd.c: Add breakpoint_proceeded definition and comment.
5221 (cont_command, jump_command, signal_command): Move call to
5222 clear_proceed_status right next to call to proceed.
5224 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5225 caller's argument while running down the chain of breakpoints.
5226 Use new variable "breakpoint_proceeded" to determine when
5227 a command that it executes moves the inferior past the
5229 (bpstat_clear): Handle NULL argument.
5230 (bpstat_clear_actions): Avoid useless call to
5231 breakpoint_auto_delete.
5232 (delete_breakpoint): Clean up bpstat's that are pointing to
5233 the deleted breakpoint from the stop_bpstat chain.
5234 (breakpoint_auto_delete): Simplify.
5236 * Clean up handling of EOF, error on stdin, etc. This was
5237 prompted by a network problem that caused gdb to go into an
5238 infinite loop filling up its malloc'd memory.
5240 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5241 not clear_breakpoints_commands, which is now gone.
5242 (main): If command_loop returns (e.g. from EOF on stdin), do
5243 a quit_command (looping back to command_loop if quit_command
5244 doesn't really quit).
5245 (command_loop): check result from command_line_input and
5246 exit if it returns NULL, rather than passing the NULL to
5248 (gdb_readline): Free malloc'd result space before returning
5251 * utils.c (query): Handle C-d to mean "yes", just as if the
5252 input was not a terminal. Also avoid infinite loop if EOF
5253 occurs in mid-input-line before newline. This allows
5254 query to be used at EOF on stdin with reasonable results.
5256 * infrun.c (proceed): Set breakpoint_proceeded.
5258 * values.c (value_as_long): Avoid infinite recursion for enums.
5259 (_initialize_values): Fix typo in help msg (kingdon).
5261 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5262 RL_LIB for linking. This allows -lreadline for linking
5263 and nothing for dependencies, once readline is a real library.
5265 * config.gdb: Jim Kingdon: give useful error message if the
5266 host or target type is not recognized.
5268 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5269 it just defines it. Dumb, but deal with it.
5271 * Jim Kingdon suggests:
5272 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5274 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5276 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5278 * Clean up Bothner's changes.
5280 * blockframe.c (clear_pc_function_cache): New function.
5281 * blockframe.c: remake cache_pc_function_* static.
5282 * dbxread.c (symbol_file_command): remove references to
5283 cache_pc_function_* variables.
5284 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5285 * printcmd.c: Avoid kludging a global variable (addressprint)
5286 to avoid printing the address of a string twice. Instead,
5287 pass the format letter 's' down low enough that it can be seen
5288 to avoid this problem.
5289 (print_formatted): Pass format arg to value_print.
5290 (restore_addressprint): Remove function.
5291 (do_examine): Avoid hacking addressprint, cleanups and such.
5292 (print_frame_args): Add a comment to a Bothner change.
5293 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5294 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5295 to wipe out the values cached in blockframe.c.
5296 * symtab.c (find_method): Add comment saying how big you must
5297 allocate to be "big enough". Per being terse again.
5298 * valprint.c (val_print): Handle format letter "s" to print
5299 strings without addresses. Add comment to vtbl printing code
5300 which casts with wild abandon. Rearrange reference-printing
5302 @0xaddr: value (print w/addressprint)
5303 value (print w/~addressprint)
5304 @0xaddr (parameter lists w/addressprint)
5305 or nothing (parameter lists w/o addressprint)
5307 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5309 * Merge more changes from Per Bothner:
5311 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5312 annoying) that I tried to improve it. Here are my suggestions.
5314 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5317 Do automatic de-reference when taking the address of a reference.
5319 Don't deref_ref when printing parameter lists.
5321 More attempts at treating refernences properly.
5323 In val_print, if deref_ref==0, don't print dangling " = ".
5325 Add COERCE_REF macro, which de-references an REF.
5327 * Merge changes from Per Bothner:
5329 * Fixed (Sony news)-specific configuration problems.
5330 * Fixed other problems with using vanilla pcc and libc (enum problems;
5331 assumption that vsprintf exists).
5332 * Some major speed-ups (finc_pc_partial_function now caches a match;
5333 parsing avoids duplicate symbol_lookup calls).
5334 * Changed handling of baseclasses (no longer use baseclasses field
5335 of struct type, use the first n_baseclasses fields instead).
5336 * Various minor changes/fixes, most C++-related.
5339 Cache the most previous match from find_pc_partial_function.
5340 (Save both low and high ends of matching function's pc range.)
5341 This speeds up the loop of infrun.c:wait_for_inferior quite
5342 a bit, and makes step/next commands much zippier.
5344 Added an enum->int cast (otherwise, some compilers barf).
5346 No longer set baseclass offset to 0, since multiple
5347 inheritance now mostly works.
5348 Added a number of casts, to shut up compiler warnings
5349 (after stabs where made enums, not ints).
5350 When discarding a symbol table (in symbol_file_command),
5351 must clear the cache introduced in blockframe.c.
5352 Don't convert $vtbl_ptr_type to vtbl any more.
5353 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5354 Mask off sign bit emitted by g++ for virtual table offset.
5355 Set voffset to -1 (not 1) for static member functions.
5357 Changed parsing/lexing of names to avoid doing symbol lookup twice
5358 (once when lexing to determine symbol class, once for real).
5359 Now only call symbol_lookup once. Fields of 'this' win especially big.
5361 Subpress printing addr twice in the case of 'x/s addr'.
5363 lookup_basetype_type is no longer used.
5364 Add find_methods as recursive helper function to decode_line_1.
5365 This allows multiple inheritance to work.
5366 Also, once one or more matches has been found, do not look in
5367 base-classes. (Baseclass methods would be overridden, anyway.)
5369 Removed baseclasses array in struct type.
5370 Instead of using baseclasses[i], use fields[i-1].
5371 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5372 Changed sign convention of voffset (previous was inconsistent).
5374 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5376 Used to assume existence of vsprintf. Re-written to not need it
5377 if HAVE_VPRINTF is undefined.
5379 typecmp was too pessimistic. Made it less so.
5381 Don't print space after address.
5382 If vtable points to a misc symbol (with 0 offset), print it,
5383 since that indicates the actual class of the object.
5384 Changed ype_print_derivation_info to use new inheritance
5385 scheme (without baseclasses vector).
5387 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5388 Also, changes needed because TYPE_BASECLASSES were removed.
5390 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5392 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5395 If there is no path set, and the symbols don't indicate what directory
5396 a file was compiled in, look in the current directory. But either
5397 a path or a known compilation directory will prevent this.
5400 Three independent bug fixes:
5401 * Remove the #if 0 block that breaks some stuff.
5402 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5403 adapt gdb to either SunOS 4.0.* or 4.1.
5404 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5407 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5410 (type_print) Demangle the name being printed.
5411 (type_print_base) Handle botched demangling without coredump (tiemann).
5414 (check_stub_method): Document routine.
5415 (tiemann) fix bug for no-arg functions
5416 Avoid clobbering beyond end of malloc'd storage.
5417 Terminate the argument list properly.
5419 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5421 * Changes merged by John Gilmore:
5424 In breakpoint_1, use new print_address_symbolic instead
5425 of find_pc_partial_function. (This forces use of assembler-level
5426 addresses, and avoids misleading non-mangled source-level names.)
5428 Generalize ansi argument such that -1 means skip arglist totally.
5429 Removed global variable print_ansi_qualifiers (which made
5430 code non-reentrant), in favor of extra explicit arguments
5431 to internal routines.
5433 Add new helper function print_address_symbolic.
5434 Use find_pc_misc_function instead of find_pc_partial_function
5435 (since we want assembler-level symbols here).
5437 Print unknown function as just "f (...)", not "f (...) (...)".
5438 Use new fputs_demangled explicitly.
5440 Fixed a typing violation (problem: value.h cannot be imported
5441 without renaming many variable in this file).
5442 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5443 decode_line_1: Moved forward some never-reached code.
5444 Made decode_line_2 skip function prologues correctly.
5446 fputs_filtered should not demangle by default.
5447 Add new fputs_demangled to demangle on demand..
5449 Change value_struct_elt to use value_primitive_field (using recursive
5450 utility function search_struct_field). This allows foo.bar to work
5451 for multiple inheritance (so far only for data fields).
5452 Change check_field in the same way (recursive helper function
5453 to support multiple inheritance).
5454 (Note: there are more of these problems that I haven't fixed.
5455 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5456 value_of_this: 'this' symbol name is now just "this", note "$this".
5458 Don't print static members.
5459 Avoid printing "members of <type>" if there are none.
5460 Simplified type_print_derivation_info by merging duplicate code.
5461 Remove useless blank lines in type_print_base (ptype command).
5463 Added declaration of new routine value_primitive_field.
5465 Added value_primitive_field which is generalized version of
5466 value_field that can handle multiple inheritance (non-zero offsets etc).
5467 Re-implemented value_field to call value_primitive_field.
5469 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5471 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5472 delete the whole environment. Karl Berry reported the bug.
5473 * source.c - fix openp to avoid //'s in filenames, which
