1 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
3 * stack.c (frame_info): Demangle the function name in `info stack'.
6 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
8 * eval.c (evaluate_subexp_for_address): Don't use
9 TYPE_POINTER_TYPE directly (it might be zero if this type has
10 never had a pointer created before); use lookup_pointer_type.
11 * symtab.c (lookup_method_type): Arguments were swapped in all
12 callers, so fix it here. I'm amazed this worked at all!
14 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
16 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
17 "bss" rather than "data" symbols, but which still conflict.
20 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
21 * core.c (core_files_info): Shorten output.
22 * exec.c (exec_files_info): Ditto.
23 (build_section_table): Ignore zero-length sections.
24 * language.c, printcmd.c: Lint.
25 * language.h (get_frame_language): Declare.
26 * saber.suppress: update.
27 * stack.c (find_relative_frame): Remove complex code that was
28 #if 0'd, stick with simple code. Lint.
29 * saber.suppress: Update a bit.
30 * symfile.c (add_symbol_file_command): Add "?" to question.
31 * utils.c (parse_escape): Avoid \a due to bdead compilers.
32 * value.h: Declare typedef_print.
34 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
37 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
38 (Reported by Mark Peek <mark@imagen.com>.)
40 * solib.c (solib_map_sections): Relocate all sections, even
41 though only the text section's size is tracked. Mark ld_text
42 for eventual elimination as we generalize to N sections.
44 * infrun.c (wait_for_inferior): Don't check if the PC is in a
45 call_dummy if we were stopped by a random signal that is being
46 passed to the program. This produced wierd results when calling
47 functions in the inferior and signals (e.g. SIGALRM) were in use.
49 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
51 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
52 Bugfix from Paul Eggert <eggert@twinsun.com>.
53 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
54 * valprint.c (print_floating): Print 9 digits for IEEE floats.

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

191 (read_dbx_symtab, case N_DEFD): Ignore.
192 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
193 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.
194 #if 0 out its uses, though, since they set a dead value.
195 * coffread.c (end_symtab): Use allocate_symtab.
196 (process_coff_symbol): #if 0'd for functions and params as above.
197 (read_enum_type): Recognize Modula-2 BOOLEAN.
198 * symtab.c (add_param_to_type): #if 0'd function to add a
199 parameter type to a function type's field list.

207 * breakpoint.c (breakpoint_cond_eval): Use new value_true to test
208 breakpoint condition language-independently.
210 * parse.c: New file with the common code remains of expread.y.
211 * parser-defs.h: New file with common declarations from expread.y.
212 * c-exp.y: New file with the C parser from expread.y, and other
213 language-specific information.
214 * m2-exp.y: New file with the Modula-2 parser and etc.
215 * expread.y, expread.tab.c: Remove.
216 * breakpoint.c, eval.c, printcmd.c, expression.h: Use
217 parse_expression and parse_exp_1 rather than parse_c_expression
220 * symtab.h (enum languages): Move to defs.h.
221 (enum type_code): Add TYPE_CODE_CHAR and TYPE_CODE_BOOL.

270 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
272 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
273 entries are enclosed herein. Not all of these changes
274 have been merged into the master GDB sources -- check the
275 ChangeLog above here for the merge log.
277 Mon Jun 3 17:05:45 EDT 1991
279 m2-exp.y Created. Tested outside of GDB for a few days. Proper
280 operators were added, C specific operators and tokens
281 removed. yylex() revamped to some extent. Still things
282 missing from the grammar, such as sets.
283 Tested for two weeks in GDB v3.5.
285 Tue Jun 11 17:23:48 EDT 1991
287 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
288 so they are built-in. Sort of a hack.
290 Fri Jun 14 12:53:51 EDT 1991
292 m2-exp.y Added range checking for numeric constants. Any numeric
293 constant is assumed to be of builtin type INTEGER unless:
294 (1) it is octal or hexadecimal, in which case it is a
295 CARDINAL; (2) it is too big to fit into an INTEGER, in
296 which case it is a CARDINAL.
297 eval.c Added simple range checking for +, -, and * on integers.
298 Doesn't work very well for *, since 6 * 1,000,000,000 =
299 1,705,032,704, which fails the simple test of result >=
300 first_operand, no matter in what order the operands are.
302 Tue Jun 18 14:11:30 EDT 1991
304 Broke the parser into parts, one containing the C grammar and the other
305 containing code to be shared by all of the grammars.
307 The following files no longer exist:
312 The following files were added:
314 c-exp.y (The C grammar)
315 m2-exp.y (The Modula-2 grammar)
316 parser-code.c (Code that is shared by the above grammar)
320 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
321 now necessary to use the Bison compiler compiler, since it
322 will generate function/variable prefixes other than yy.
324 Tue Jun 18 16:47:49 EDT 1991
326 symtab.[ch] Added the external variable working_lang, than holds the
327 value of the current working language.
328 Added the ennumerated type language_mode, with the values
329 language_auto and language_manual, the former meaning that
330 GDB sets working_lang as needed, and the latter meaning
331 that the value of working_lang is totally under user
333 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
334 REAL, BOOLEAN and CHAR. Also added the type codes
335 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
336 utils.c Added set_language_command and show_language_command to
337 implement the GDB support commands "set language" and
339 expression.h A number of identifiers were added to the type exp_opcode
340 to facilitate Modula-2 builtin functions, integer
341 division, and array indexing.
343 Wed Jun 19 13:25:58 EDT 1991
345 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
346 if the language specified by working_lang requires the use
347 of strict typing of expressions. Eventually, even this
348 will be able to be changed by the user.
349 Added the macro RANGE_CHECK, which evaluates to non-zero
350 if the language specified by working_lang requires the
351 checking of a value against the domain of its type.
352 Eventually, even this will be able to be changed by the
354 language.[ch] Predicates involving types (simple_type, ordered_type,
355 same_type, integral_type, numeric_type, character_type,
356 boolean_type, float_type) are added. These predicates are
357 based on the current value of working_lang, and are handy
360 Wed Jun 19 15:39:34 EDT 1991
362 eval.c Added the function type_array_rank which computes the rank
364 valarith.c Added the funtion value_bool, which when given a integer
365 value.h value (ie. struct value *) as an argument, it returns a
366 boolean value (ie. struct value *) true if that integer
367 is non-zero, and a boolean value false otherwise.
368 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
369 will print out properly.
371 Wed Jun 19 16:36:34 EDT 1991
373 valops.c Added the function value_capitalize, which returns it
374 value.h argument capitalized if its argument is a lowercase
375 letter, or the argument unchanged if its argument is not a
377 valarith.c Added the function range_check_p, which returns non-zero
378 value.h if its value argument is between the integral bounds upper
380 Added the function range_check_enum_p, which makes sure
381 that its value argument is a valid member of the domain of
383 Added the function range_check_range_p, which makes sure
384 its value argument lies between the upper and lower bounds
385 of its type argument, which must be a ranged type.
386 Added the function check_array_index, which range and type
387 checks an index of an array.
388 Added the function value_multi_subscript, which computes
389 array[idx1,idx2...idxN], given a value array and an array
390 of values representing indicies.
391 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
392 unpack_long to work with TYPE_CODE_BOOL and
395 Wed Jun 19 18:04:08 EDT 1991
397 symtab.c Stored pervasive types in a structure and make
398 lookup_pervasive_type() a lookup function that was based
399 on working_lang. If lookup_pervasive_type() returned
400 non-zero, then that value was returned (a fix, since
401 before it simply wouldn't return the pervasive type.)
402 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
403 non-zero if the language specified by working_lang means
404 "conversion" when it says "cast".
405 valops.c Added the function value_real_cast(), which performs a
406 value.h *cast*, not a *conversion*, which is what value_cast()
407 does when it can. In particular,
408 value_cast(<float_type>,4) = 4.0, while
409 value_real_cast(<float_type>,4) = some mess.
410 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
411 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
412 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
413 and MIN on integral types. *NOTE*: These are currently
414 hardcoded to work only if there are 8 bits per storage
416 eval.c Made logical functions call value_bool to return a
417 properly typed boolean value, based on working_lang.
419 Thu Jun 20 11:55:27 EDT 1991
421 valprint.c Types now print out in a Modula-2 fashion. This works for
422 the cases when the type is printed out step-by-step, that
423 is, it doesn't work when the name of a structured type
424 (which includes the keyword "struct", etc.) is simply
426 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
427 since type specifications in C and Modula-2 are very
428 different. The C printing of a type is very recursive,
429 whereas in Modula-2 it is generally very simple. C has
430 type prefixes and suffixes, which have no real analogue in
431 Modula-2. Maybe type_print() should call a language
432 specific type printer. This is also advantageous if we
433 compile GDB to exclude some of the languages. We'll just
434 leave those functions out.
436 Thu Jun 20 16:57:10 EDT 1991
438 dbxread.c When reading the complete symbol table in (via
439 psymtab_to_symtab()), the number and types of function
440 arguments are added to a function type. define_symbol()
441 calls add_param_to_type() to accomplish this.
442 Assumption: when we come across a function definition
443 (N_FUN symbol with an 'f' or 'F' in the name), its
444 arguments will appear before another function definition.
445 When a function is found, a pointer to its type is placed
446 in the global in_function_type. Changes that
447 add_param_to_type() makes are to this global.
448 valprint.c The type of a function now includes (for Modula-2) the
449 types of its parameters.
450 eval.c Type checking and a check for the proper number of
451 arguments is now done for function calls. Not sure of the
452 impact this has on C++ member function yet.
454 Thu Jun 20 19:58:48 EDT 1991
456 valprint.c Rewrote the type printer. Broke it into two language
457 specific parts, adding the functions type_print_m2() and
459 An unfortunate consequence is this: if you debugging a C
460 program in Modula-2 mode (why?), info types does not work
461 well with regular expressions, since the types are printed
462 out in Modula-2 terminology, but stored in C terminology.
463 language.[ch] Added the functions new_type_last(), type_keyword(), and
464 type_sep() to aid in the printing of typedefs.
465 symtab.c Made the printing of typedefs as language independent as
466 possible through calls to new_type_last(), type_keyword(),
469 Fri Jun 21 11:50:26 EDT 1991
471 dbxread.c Check all incoming ennumerated types. If it looks like
472 Modula-2's BOOLEAN type, then change the type_code of the
473 type to TYPE_CODE_BOOL so we can process it as a boolean
475 valprint.c Replaced some of the 0x%x with calls to sprintf and
476 hexformat() in val_print().
477 language.[ch] Added the function hex_to_string(), which converts its
478 integral argument to a hexadecimal number (format is
479 language based) and returns the result as a string.
481 Mon Jun 24 12:25:07 EDT 1991
483 valprint.c Some functions call type_print_1() directly, instead of
484 value.h using type_print(), so they can specify where (column) to
485 print things. Since type_print() takes care of language
486 dependence, that needs to be called first. Added a
487 parameter depth to type_print() (so it is now like
488 type_print_1). Changed type_print to type_print_at, and
489 made type_print a macro that passes a depth argument of
491 symmisc.c Changed all calls to type_print_1 to calls to
493 Makefile.dist Made it possible to build GDB for a specific set of
494 depend languages. Do this by passing a definition for the macro
495 LANGS to make. LANGS should be a string containing a
496 space-separated list of language names (ie. LANGS="c m2").
497 The default is to build all languages. Note that grammar
498 files must follow the naming convention of <lang>-exp.y.
499 gdb.lang This holds the current value of the LANGS macro. It is
500 examined every time make is called, and is updated if
502 eval.c Added #ifdef _LANG_<lang> to these files.
503 expread.c Still need to add them to dbxread.c and coffread.c.
511 Mon Jun 24 16:33:11 EDT 1991
513 language.[ch] Added the functions hexformat_pre() and
514 hex_to_string_pre(), which take a prefix argument to
515 include in the format string. Thus, hexformat_pre("08") will
516 return "0x08x" (if the working language is language_c).
517 Made hexformat() and hex_to_string() calls to the above
518 with "" as the prefix argument.

528 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
529 calls to hexformat() and hex_to_string(). Format strings without
530 the leading "0x" were ignored.
532 depend Updated to take the above into account.
535 Tue Jun 25 15:27:18 EDT 1991
537 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
538 and type_check_t to keep track of the current state of
539 range and type checking.
540 main.c Added the variables range_mode, range_check, type_mode,
541 and type_check to record the current state of range and
542 type checking. Added initialization code to main().
543 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
547 Tue Jun 25 17:57:08 EDT 1991
549 dbxread.c process_one_symbol() updates the variable (enum language)
550 source_lang based on the extension of the filename
551 contained in the N_SO sybmol that started this symtab.
552 When end_symtab() is called, the value of source_lang is
553 put into the language field.
554 stack.c select_frame() sets working_lang (and possibly type_check
555 and range_check) to the language field of the symtab
556 associated with the frame that is selected if working_mode
557 is language_auto. If working_mode is language_manual, a
558 warning is printed and working_lang is not set.
559 language.c Added the function set_type_range(), which sets the value of
560 type_check and range_check (if their modes call for
561 automatic setting) based on the current value of
562 working_lang. A non-zero argument will cause the current
563 settings to be output.
566 Wed Jun 26 14:51:40 EDT 1991
568 eval.c Added range checks on assignment.
569 m2-exp.y Added the grammar for sets to the language. Currently,
570 these do not do anything except print an error message.
572 Wed Jun 26 17:01:04 EDT 1991
574 m2-exp.y Added the ability for parse_number() to parse negative
575 numbers. A global flag is set upon encountering a unary
576 minus. This was done to make, for example, 1 parse as a
577 CARDINAL, and not as an integer, per Wirth's examples in
578 Programming in Modula-2 ed.4.
579 valprint.c Added support for "set radix 2" by then setting
580 output_format to 't'.
581 eval.c Implemented range checking on subrange types. Added calls
582 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
583 Implemented MIN and MAX for ennumerated types. The
584 minimum value of an ennumerated type is defined by Wirth
585 as the first identifier, and the maximum as the last.
586 m2-exp.y Made octal numbers ending with "B" be characters and those
587 ending with "C" be numbers, per Wirth's book. (p. 34)
589 Thu Jun 27 14:11:52 EDT 1991
591 stack.c select_frame() now only sets working_lang, it does not
592 notify the user. If working_mode is language_manual, then
593 a warning is issued once.
594 main.c At the end of each call to execute_command(), working_lang
595 is checked against the local static (enum language)
596 current. If they differ and working_mode is
597 language_auto, the new settings of language, type and
598 range checking are printed out.
599 stack.c Modified frame_info() to include the language of the
600 current frame in the output of "info frame".
601 language.[ch] Added the function language_str() which returns the name
602 of the current language.
604 Fri Jun 28 15:33:14 EDT 1991
606 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
607 the language. INCL and DECL currently cause an error,
608 since sets are not implemented yet. INC and DEC are
609 implemented as PREINCREMENT/PREDECREMENT with one
610 argument, and as ASSIGN_MODIFY with two arguments.
611 eval.c Added type checking to the above cases.
612 value.h Added not_lval_constant to the lval_type ennumerated type.
613 not_lval_constant means that the value is a constant
614 value; that is 3 or 'a' or TRUE, not as in a constant
615 identifier. This is used to help coerce numbers such as 3
616 to either signed or unsigned numbers.
617 valops.c Added the function value_coerce_constants() which coerces
618 constant integers as following: if one is a constant and
619 the other is not, the constant's type is set to the type
620 of the other argument. If both are constants and one is
621 signed, the other is converted to a signed constant.
623 Sat Jun 29 17:26:29 EDT 1991
625 valarith.c Added a better range checker. It now checks range
626 (successfully) on integral operations [+-] (signed and
627 unsigned) for any C sized type. Still does not work well
629 int_in_size() returns an integer that is coerced to fit into
630 specified number of bytes.
632 Mon Jul 1 13:04:14 EDT 1991
634 language.[ch] Added the function binop_result_type(), which returns the
635 builtin (struct type *) type that would be the result of a
636 binop on the two values V1 and V2.
638 Wed Jul 3 19:22:53 EDT 1991
640 source.c Extended source_info() to include the source language in
641 the output from "info source".
643 Fri Jul 5 13:48:52 EDT 1991
645 utils.c Moved the support functions for the GDB set/show commands
646 dealing with language into language.c.
647 language.c Added the function language_info(), which displays info
648 about the current working language, type and range check
649 settings. Called via the GDB command "info language".
650 Added an initialization routine _initialize_language(),
651 that sets defaults for the language, type and range
652 variables and sets up the new GDB commands.
653 main.c Language setup moved to language.c.
656 Mon Jul 8 10:10:22 EDT 1991
658 valarith.c Debugged the range checker for arithmetic. Still does not
659 work for multiplication very well.
661 Mon Jul 8 12:40:37 EDT 1991
663 language.[ch] Added the function value_true() which returns non-zero if
664 its argument represents a boolean true value.
665 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
666 check the truth of an expression.
668 Thu Jul 11 12:51:34 EDT 1991
670 language.[ch] Added the predicate structured_type(), which returns
671 non-zero if the argument is a structured type.
672 Added the predicate pointer_type(), which returns non-zero
673 if the argument is a pointer type.
674 eval.c Added the ability to do addition and substraction on
675 pointers and integers. This case simply bypasses the
678 Thu Jul 11 14:41:42 EDT 1991
681 Added the symbol N_DEFD (0x4a) which is a definition
682 module dependency that is used by the GNU Modula-2
683 compiler and the linker. It is not important to GDB,
684 except that [dbx|coff|mips]read.c should ignore these
687 Fri Jul 12 16:07:00 EDT 1991
689 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
690 0 in val_print(). Also added statements to the else part
691 to coerce type (argument to val_print) to a pointer type
692 if it is an "array of unspecified length".
693 valops.c Added the function value_m2_string(), which returns a
694 (value) value which is a constant string, whose type is
695 (ARRAY [0..n] OF CHAR). The length field of the type
696 structure is set to zero, so it will be interpreted as an
697 "array of unspecified length".
698 stack.c Moved the language/frame mismatch check to
699 main.c:execute_command().
700 main.c The working language is recorded each time
701 execute_command() is executed. If working lang has
702 changed during its execution, then the new
703 language/type/range info is printed out for the user. If
704 the working language does not match the language of the
705 frame, a warning is issued.
707 Sat Jul 13 16:16:39 EDT 1991
709 eval.c Moved all the type-checking stuff for operators to
710 language.[ch] language.c. This is so we can keep language-specific
711 stuff (like for what type operators are defined) in
713 language.[ch] Added the function binop_type_check(), which checks to see
714 if its two (value) arguments are type-compatible with its
715 opcode argument. The opcode should represent an operation
716 involving an operator. Also added the macro function
717 unop_type_check, which calls binop_type_check with a
718 NULL second argument.
719 expprint.c Added Modula-2 operators to the op_print_tab, so info
720 expression.h break works correctly. Also added "op_string", which
721 returns the string corresponding to the (enum exp_opcode)
722 opcode that is its argument.
725 Sat Jul 13 18:26:18 EDT 1991
727 coffread.c Added code to record the type of function arguments with
728 each paricular function. Code is very similar to that
730 dbxread.c Moved add_param_to_type() to symtab.c
731 symtab.[ch] Added function add_param_to_type() from dbxread.c
733 *** NOTE: The above additions have not been tested.
735 Mon Jul 15 12:50:47 EDT 1991
737 langauge.[ch] Added the functions type_error and range_error, which work
738 like error() except if the type/range mode is set to
739 *_mode_warn, then they do not do a return_to_top_level(),
740 but merely print a warning.
741 Also changed [set|show]_[type|range]_command() to support
742 the new "warn" feature.
744 Thu Jul 18 17:50:54 EDT 1991
746 mipsread.c Added code to record the type of function arguments with
747 each particular function. Code is very similar to that
750 *** NOTE: The above additions have not been tested.
752 Fri Jul 19 11:19:10 EDT 1991
754 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
755 UMIN_OF_SIZE, which when given a size of a numeric type,
756 return the maximum and minimum value it can hold. UMAX...
757 and UMIN... return the result for unsigned types.
758 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
759 struct types. They call above macros.
760 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
761 avoid a name conlict with the above.
762 c-exp.y Added range checking on numeric constants in
763 parse_number() for completeness.
764 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
765 return 0 if working_lang is not language_c.
767 Thu Aug 8 14:17:22 EDT 1991
771 breakpoint.c Documentation strings of some commands changed to
772 eliminate the references to the C language where
775 Tue Aug 13 15:48:03 EDT 1991
777 m2-exp.y Added qualified identifiers to the grammar. The semantics
778 are slightly different from those of the GDB operator ::
780 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
781 type_exp, where type_exp is any valid type expression.
783 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
784 printcmd.c Modified ptype_command() so it actually parses the input
785 (necessary for type expressions with scope qualifiers).
786 Added the function ptype_eval() which expects an
787 expression composed of one OP_TYPE element.
788 *.[ch] Replaced all occurences of parse_c_expression with
790 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
792 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
794 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
796 Small fixes from Peter Schauer:
798 * infrun.c (child_attach): Lint.
799 * solib.c (find_solib): Handle shared libs version 2.
801 Small fixes from David Wood:
803 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
807 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
808 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
810 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
811 chars_per_line is at maximum (user typed `set width 0'). Fix
812 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
814 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
816 * coredep.c: include ptrace.h where necessary.
817 * mipsread.c(parse_lines): fix unsigned char problem that was
818 messing up line numbers on SGI's and possibly other MIPS based
820 * infrun.c (child_create_inferior): use better test to check
821 return val from setpgrp().
822 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
823 for sgi/irix support.
825 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
827 * mipsread.c (parse_symbol): Put non-static procedures
830 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
832 Patch together `text_start' and `text_end' for 29K port.
834 * exec.c (exec_command): If NEED_TEXT_START_END, define the
835 variables and set them based on the exec file.
836 * am29k-tdep.c: declare text_start.
837 * valops.c (call_function_by_hand): declare text_end.
839 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
840 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
841 because machines that do this will also have to know to
842 set NEED_TEXT_START_END. Besides, it was a redundant way to
844 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
845 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
848 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
850 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
852 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
853 Pass MUNCH_DEFINE to munch whenever we run it.
854 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
855 format string; use 0x%x instead.
856 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
857 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
858 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
859 * inflow.c: Handle `short' process group IDs.
860 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
861 and check for ptrace errors.
862 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
863 (coff_symfile_init): Initialize text_bfd_scnum.
864 (read_coff_symtab): Use it to find the text [and absolute?] sections.
865 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
866 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
867 Merge target arm case with other "easy" cases. Add target
868 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
869 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
871 * minimon.h, remote-adapt.c, remote-mm.c: Add.
872 * munch: Cope with RT/PC putting fns in data segment.
873 Restore ability to override `nm' by specifying MUNCH_NM.
874 * xconfig/rtbsd, xconfig/ultra3: New host systems.
875 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
876 and remote-adapt. Remove encapsulated coff #define's (the
877 support should go in BFD, and gdb shouldn't know or care).
878 * tconfig/a29k-kern: Same, but for remote kernel debugging.
879 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
880 * tm-29k.h: Update BADMAG (though it should go away).
881 Allow the register definitions to be overridden in another
882 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
883 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
884 DUMMY_SAVE_GR96, for handling kernel calling conventions
885 that use GR64+ rather than GR96+.
886 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
887 remote debugging of Ultra3 kernel. Includes tm-29k.h and
888 overrides various things.
890 * remote-mm.c (mm_attach, mm_wait): Handle attach like
891 child_attach does, making a clean stop in the newly attached
895 * coffread.c: Make coffread independent of any particular
896 variant of COFF. Avoid #include-ing any particular one except
897 internalcoff.h. BFD now passes key values for symbol reading
898 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
899 and the symbol masks and shifts); use them.
900 Remove obsolete end_of_text_addr.
902 * exec.c: Remove unused include files.
904 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
906 * Makefile.in (documentation targets): Pass $(M4).
907 Bugfix from eggert@twinsun.com (Paul Eggert).
909 * stack.c (down_silently_command): Check for stack existence.
911 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
913 * Makefile.in (VERSION): Update to 4.0.3.
915 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
917 * core.c (core_file_command): Print frame at coredump with
918 its level number, by calling print_stack_frame.
919 * frame.h: Add selected_frame_level, print_stack_frame.
920 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
921 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
922 Change print_sel_frame and print_selected_frame callers to
925 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
926 * symfile.c (free_named_symtabs): Ditto.
927 * main.c (main): wrap_here needs an arg.
928 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
929 (solib_add): Avoid noise.
930 (solib_create_inferior_hook): Lint.
931 (sharedlibrary_command): Move dont_repeat to here.
932 * utils.c (error): Call wrap_here to force buffered output.
934 Small patches from Peter Schauer:
936 * coffread.c (start_symtab): Free any existing line_vector before
938 (read_coff_symtab): Ditto for type_vector.
940 * source.c (lines_to_list): New variable, replacing function.
941 (all uses): Use as variable.
942 (_initialize_source): Add 'set listsize' and 'show listsize'.
943 * utils.c (lines_to_list): Remove function.
944 * stack.c (print_frame_info): Use as variable.
945 * defs.h (lines_to_list): Remove declaration.
947 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
949 * breakpoint.c (insert_breakpoints): Restore warning about
950 the program might be running in another process, but only for
951 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
952 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
954 * utils.c (error): if error_pre_print is set, print the string
956 * main.c (main, print_gnu_advertisement, print_gdb_version):
957 Reformat legalese so it always prints, but acts as an "I'm here"
958 message while symbols are being read. If any errors occur,
959 print a few newlines to set off the message and start it at the
960 left margin. Remove mention of "help" command, and don't yak
961 about symbol reading.
962 (catch_errors): Error string is now printed first in case of
964 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
965 suggest the "help" command.
967 * Makefile.in (VERSION): Set to 4.0.2.
969 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
971 * .gdbinit: Remove useless "rr" command. Set complaints
972 to 1 for people debugging gdb.
974 * breakpoint.c, remote-vx.c: Reword strings printed by
975 catch_errors callers.
977 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
979 * WHATS.NEW: "history write -> history save". Doc "write on/off".
980 (Fix from kenc@viewlogic.com.)
982 Fix some infrastructure to be able to cope with host and target
983 machines with different sized basic types (ints, ptrs, etc).
984 (Idea from pierre@la.tce.com (Pierre Willard).)
986 * values.c (value_from_longest): Rename from value_from_long.
987 Handle pointer types as well as integers, so that targets with
988 different pointer sizes from the host can be accomodated.
989 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
990 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
991 uses of value_from_long to value_from_longest.
992 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
993 the correct pointer type to value_from_long{est}.
995 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
997 * remote-vx.c: Remove obsolete code for calling functions via
998 vxworks kludge interface (it referenced value_from_long).
1000 * valops.c (value_string): Find malloc with lookup_misc_func, not
1003 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1005 Make writing to files work properly. (Fixes to BFD are also needed.)
1007 * core.c (core_open): Open file ourselves, read or r/w, depending on
1008 write_files. Use bfd_fdopenr.
1009 * gdbcore.h (write_files): New variable.
1010 * exec.c (write_files): Define variable, add set&show for it.
1011 (exec_file_command): Use write_files to open for read or r/write.
1013 Make shared library reading happen automatically. These changes
1014 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1016 * inferior.h (stop_soon_quietly): Add to exported variables.
1017 * infrun.c (child_create_inferior): call solib hook, if defined.
1018 (child_attach): call solib hook, if defined.
1019 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1020 (find_solib): Use lookup_misc_func rather than hand-rolled.
1021 (symbol_add_stub): New stub for catch_errors.
1022 (solib_add): Avoid output if !from_tty. Catch errors rather
1023 than just calling symbol_file_add and bombing.
1024 (solib_create_inferior_hook): Interface with the target process
1025 to let it read and alloc shared libs, then figure out what it did.
1027 * core.c (validate_files): Fix typo, soften warning.
1028 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1030 * utils.c (fputs_demangled): Avoid duplicate printing if
1031 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1033 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1034 (Fix from pierre@la.tce.com (Pierre Willard).)
1036 * main.c (catch_errors): Change argument to a char * from an int,
1037 since a char * can point to a struct full of glop, but an int
1038 is not guaranteed to be able to hold a pointer.
1039 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1040 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1041 * core.c (core_open, solib_add_stub): Adapt.
1042 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1044 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1046 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1047 by adding .NOEXPORT target.
1049 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1053 * Makefile.in (VERSION): Roll to 4.0.
1054 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1056 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1058 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1061 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1064 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1066 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1067 reflect above name change
1069 * WHATS.NEW: correct pointer to refcard.
1071 * doc/gdb.texinfo: update New Features, Installing
1073 * doc/gdbint.texinfo: add short description of configure +template
1075 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1077 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1079 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1081 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1082 tar file, add dependencies for referenced doc files.
1084 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1086 * coffread.c, symfile.c, stack.c: saberized.
1088 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1090 * doc/refcard.tex: permuted Essential Commands sec
1092 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1094 set/show symbol-reloading
1095 default set complaints 0
1097 RET-repeat disabled after prompted long displays
1098 processID (attach) interpretation of 2nd GDB cmdline arg
1100 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1102 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1103 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1104 breakpoint.c, main.c: lint.
1106 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1108 Install new configuration scheme for GDB and friends.
1110 * config.sub: Translate ordinary names to three-part names.
1111 * configure: Use three-part names internally.
1112 * configure.in: Translate three-part names to filenames.
1114 * README, WHATS.NEW: Update for gdb-4.0.
1115 * Makefile.in: Roll VERSION to 3.99.
1117 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1119 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1120 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1121 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1122 to single structures rather than arrays; when passing
1123 their address, use &. This avoids trouble with bdead compilers.
1124 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1125 instead. This avoids portability headaches.
1126 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1128 * source.c (open_source_file): Avoid ANSI const bdeath by
1129 skipping declaration and then casting result value.
1130 * tm-hp300bsd.h: Clarify comment.
1131 * utils.c (strstr): Result is const char *; ANSI bdeath.
1132 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1133 since system include file defines it differently from "defs.h",
1134 though the two are equivalent for our purposes.
1135 * tconfig/hp300bsd: Add m68k-tdep.o.
1137 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1139 * tconfig/sun*4: Remove warnings about system assembler.
1141 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1143 * mcheck.c: Avoid warning about undeclared abort fn.
1144 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1145 it causes recursive calls to error() when used in cleanups.
1146 To do so requires that we make it a function, so we do.
1147 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1148 * utils.c (do_cleanups): Remove the current cleanup from the
1149 chain *before* calling it, in case error() is called from it.
1150 The result won't be pretty, but won't be an infinite loop either.
1152 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1154 * dbxread.c (read_struct_type): Grok anon structs for C++.
1155 (vb_name, vptr_name): Null terminate these strings.
1157 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1159 Minor bug fixes from BSD Net2 gdb:
1161 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1162 returns 0, there is no previous frame.
1163 * breakpoint.c (commands_command): If !from_tty, don't call
1164 input_from_terminal_p().
1165 * dbxread.c (record_misc_function): Speed up slightly.
1166 (compare_psymbols): Ditto.
1167 * infcmd.c (do_registers_info): Take a second argument to
1168 determine whether to print float registers. "info registers"
1169 does not do so anymore. "info all-registers" does, now.
1170 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1172 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1173 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1177 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1178 executing_breakpoint_commands if we are interrupted by error.
1179 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1180 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1181 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1182 catch_errors() so we can setup the frame regardless of whether
1183 the shared libs work.
1184 * ieee-float.c (double_to_ieee_extended): Get exponent from
1185 right place in little-endian systems. From John Carey.
1187 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1189 * main.c: Remove unused terminating_signals and catch_termination().
1190 (long_options): Terminate with a zero element.
1191 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1192 (gdb_readline): Make call-compatible with readline.
1193 (init_signals): Improve comments re vfork vs. signal.
1195 * utils.c (prompt_for_continue): Use new gdb_readline().
1196 If we prompt for continuation, we don't let CR repeat the previous
1197 command, once we get back to a prompt. It's too easy to keep
1198 hitting CR, expecting "--more--" prompts, and have some long
1199 command start repeating on you.
1201 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1203 * blockframe.c (frameless_look_for_prologue): Speed up by
1204 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1205 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1206 Define two variants, one faster.
1207 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1208 and return zero, rather than giving an error.
1209 (setup_arbitrary_frame): Initialize the PC in the new frame.
1210 (skip_prologue): Add a second arg saying whether we're just
1211 checking for a frameless function or not.
1213 * core.c (core_open, core_close, core_xfer_memory): Move
1214 section table pointers and bfd* into the target_ops.
1215 (core_open): Allow errors in shared lib reading, etc.
1216 (core_files_info): Describe shared library sections.
1218 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1219 exec_files_info, set_section_command): Move section table
1220 pointers and bfd* into the target_ops.
1221 (add_to_section_table): Add BFD to section table.
1223 * target.c (target_xfer_memory, target_info): Pass target to
1224 xfer_memory and target_info functions.
1227 * gdbcore.h: Move struct section_table.
1228 * target.h: New home of struct section_table.
1230 * solib.c (solib_add): New argument is the target_ops whose
1231 section list is to be added to, if any. Reallocate the
1232 sections in that target to add any that come from shared libs.
1233 (throughout) so_sections renamed to sections.
1234 (solib_xfer_memory): Deleted.
1235 * tm-sunos.h (SOLIB_ADD): Add target argument.
1236 (SOLIB_XFER_MEMORY): Delete.
1238 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1239 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1240 from target_ops. It's the same on all targets. Add two section
1241 pointers to target_ops.
1243 * stack.c (find_relative_frame): Dump ancient algorithm for
1244 "down", just use handy "next" pointers.
1245 (frame_command): Don't error if there is no stack; let user
1248 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1249 modifies static state in the parent process; new_tty itself
1250 runs in the child and modifies the child's file descriptors
1251 to match the saved static state.
1252 * infrun.c (child_create_inferior): Call new_tty_prefork,
1255 * infptrace.c (child_xfer_memory): Add ignored target arg.
1256 * remote-eb.c (eb_xfer_inferior_memory): ''
1257 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1258 * remote-vx.c (vx_xfer_memory): ''
1259 * remote.c (remote_xfer_memory): ''. Rename from
1260 remote_xfer_inferior_memory.
1262 * main.c (main): Only try to attach "corefile" argument if
1263 it starts with a digit.
1265 * symfile.c (symbol_reloading): New "set/show" variable.
1266 (symbol_file_add): Shorten message about symbol reading.
1267 (add_symbol_file_command): Merge with add_syms_addr_command,
1268 since this should work on all targets now.
1269 (stop_whining): Default to zero, to shut up complaints
1270 about bad symbol tables on many systems.
1271 (free_named_symtabs): Just exit unless symbol_reloading.
1273 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1274 and add comment explaining shared library screw.
1276 * source.c: #if defined => #ifdef.
1278 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1280 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1282 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1284 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1285 (doc/Makefile knows how to make one for local config)
1287 * Makefile.in: use doc/Makefile for doc targets
1289 * doc/Makefile: GDB documentation now has its own Makefile
1290 doc/refcard.tex: renamed from "gdbrc.tex"
1291 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1292 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1295 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1297 * values.c (baseclass_addr): When reading target memory, use the
1298 length of the basetype, not the upper type. We've only malloc'd
1299 enough space for the basetype, leading to errors in free().
1301 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1302 ends up as a function specially, since we know the actual type of
1303 the pointed-to address. This (somewhat) fixes display of
1304 expressions that include misc_function_vector names. Try `cond 1
1305 !strcmp("a","b")' then `i b'.
1307 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1308 The child can be proceeded from inside wait_for_inferior in
1309 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1310 getting skipped in that case.
1312 * expprint.c (print_subexp): Use filtered output, since the
1313 subroutines we call use it, otherwise the output is horribly
1314 mangled, since output of wrappable stuff comes out late.
1316 * Makefile.in: Bump VERSION to 3.98.1
1318 * infrun.c (child_create_process): Use execlp to find the
1319 shell to exec our target program. This requires some fiddling
1320 with `environ' since there is no execlpe().
1322 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1324 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1325 Minor rearrangement of refcard permits two new make targets--
1326 gdbrc.dvi DVI output for refcard, using CM fonts
1327 gdbrc.ps PostScript refcard, using PS fonts
1329 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1333 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1334 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1336 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1338 * doc/gdb.texinfo: last changes for release.
1339 Minor typo and formatting fixes; incorporated most fixes remaining from
1340 filed mail commenting on earlier drafts.
1342 Added warnings: pipes don't work in run command;
1343 conditions are converse of assertions;
1344 step over fn without debug info goes to next fn;
1345 vars may have "wrong" values near fn entrance, exit
1347 Added example from Kingston on printing repeated nonadjacent values
1349 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1350 shell mode for signals
1352 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1353 doesn't sound so much like its parent "Stopping and Continuing"; also
1354 moved entries on continue to top of section, so they don't get lost.
1356 Improved installation directions in appendix, added manual formatting
1359 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1361 * configure.in: Remove xm.h and tm.h even if we aren't linking
1362 new ones, so "./configure sun4; ./configure none" does the right
1363 thing. Assume that alldeps.mak and depend are already built in
1364 srcdir, and avoid running "make" (particularly "make depend",
1365 which involves "gcc") from inside configure. Build Makefile
1366 directly rather than building Makefile.conf first.
1367 * configure: Regenerate with above changes.
1368 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1369 to 3.98. Revise gdb.tar.Z procedure to produce a file
1370 called gdb-$(VERSION).tar.Z but which unpacks into a
1371 directory called "gdb". Move non-source files out of
1372 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1373 (depend): Don't try to do "gcc expread.y".
1374 (expread.o): Update dependencies by hand.
1376 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1379 Fixed a variety of small typos that prevented info from formatting
1380 cleanly; altered too-long heading for GPL Appendix, as discussed
1381 w/RMS; Changed date on cover to July 91.
1383 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1386 (1) Applied some fixes due to comments from Larry Breed (easier ones
1387 through chapsec 5.2)
1388 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1389 it's broken in latest texinfo
1390 (3) Introduced *some* use of [] for optional arguments, where
1391 explanation is not simpler by listing cmd w arg and cmd w/out arg
1392 separately. Still not using @deffn.
1393 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1394 couple of headings are too long. Need patches to texinfo or revision
1397 * Partial update to README (which still needs work for this
1398 release!): (1) use of configure corrected for new script,
1399 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1401 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1403 * symtab.c (lookup_symbol): Don't complain right off about
1404 no debug symbols; use the misc function vector first.
1405 (list_symbols): Use misc function vector to find symbols
1406 that don't have debug info, and print them.
1407 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1408 PC range doesn't match symtab PC range, as it does on the
1409 MIPS because our symtab reading isn't perfect.
1411 * dbxread.c (dbx_symfile_read): Make warning about
1412 "no debug symbols" slightly nicer.
1414 * source.c (select_source_symtab): If "main" symbol exists,
1415 but decode_line_spec can't find line info, don't just return
1416 a zero; try other source symtabs or give an error.
1418 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1419 their low addresses first, then rip through fixing high addrs.
1421 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1422 <runene@ifi.uio.no>.
1423 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1425 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1427 * Minor, mostly mechanical, cleanup of doc subdir for clean
1428 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1429 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1431 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1433 Mostly MIPS and general symbol-reading fixups.
1435 * doc/gdbint.texinfo: Add documentation on symbol-reading
1438 * mipsread.c: Remove kludges around #include "ecoff.h".
1439 Remove redefinitions of a_magic, etc, no longer used.
1440 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1441 Fix global overview comments to match symfile.c protocol.
1442 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1443 (mipscoff_symfile_read): Eliminate unused code. Avoid
1444 sorting all the symtabs, when all we have read here is psymtabs.
1445 The symtabs are sorted as they are created anyway. Tell
1446 condense_misc_bunches whether we're mainline.
1447 (psymtab_to_symtab_1): Pass filename when recursing, to make
1448 stack trace more informative.
1449 (parse_partial_symbols): Assume cur_hdr as argument.
1450 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1451 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1452 the TYPE_NAME of char *, since that's done in symfile.c.
1453 (free_numargs, parse_symbol, add_symbol, add_block,
1454 shrink_linetable): Declare these fns void.
1455 (upgrade_type): Convert tree of if's to switch. Clean up
1456 bogus "off == 0" handling with a complaint. Avoid setting
1457 field bitpos and bitsize of array with lower and upper bounds.
1458 Check specified bitsize of elements against their actual type's
1459 bitsize, and complain if different. Complain about unknown
1461 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1462 (psymtab_to_symtab_1): Print names of subsidiary files that
1463 are being read in. FIXME, we read far too many files. This code
1464 is not the problem, the problem is in parse_fdr where the psymtabs
1466 (cross_ref): Result should indicate that we used one aux entry
1467 normally, or two if we encountered a "next" entry. This used
1468 to leave the caller pointing at the wrong aux entry.
1469 (add_symbol): If overflowed cur_block, reallocate it larger,
1470 chase all pointers to it, and complain(), rather than clobber memory.
1471 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1472 (new_field): Only allocate one field initially, not two.
1473 Pull ++ out of macro argument. Simplify.
1474 (_initialize_mipsread): Avoid initialization of importd
1475 global_psymbols and static_psymbols.
1477 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1478 to properly set pst->symtab; avoid searching for it.
1479 (symfile_fns): Improve comments, add a FIXME.
1480 * dbxread.c: Update comments to reflect symfile protocol.
1481 (read_ofile_symtab, end_symtab): Return the symtab.
1482 (psymtab_to_symtab_1): Set pst->symtab.
1484 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1485 whether we're mainline.
1487 * symfile.h (sym_fns): Remove unused sym_discard member.
1488 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1490 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1491 the environment variable is not.
1492 * infcmd.c (finish_command): Use filtered printfs.
1493 * cplus-dem.c: Add struct tags to a few unnamed structs.
1494 * valops.c (value_coerce_array): Improve comments.
1495 * valprint.c (type_print_varspec_suffix): Print array size only
1496 if greater than zero.
1497 * m88k-tdep.c: Shift some lines left by one space, that had
1498 apparently been trashed at some point.
1499 * TODO: More things to do, a few got done.
1501 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1503 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1504 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1506 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1507 * expread.y, findvar.c, symmisc.c: Ditto.
1508 * printcmd.c (address_info): Update printed forms of LOC_
1509 symbols. Elim LOC_EXTERNAL.
1510 (print_frame_args): Keep track of param stack offsets before
1511 re-looking up to find the local register param is kept in.
1513 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1514 Further integration of mipsread into gdb. Eliminate unused
1515 routines, duplicate declarations. Handle static symbols in
1516 psymtabs as well as external symbols. When reading symtabs,
1517 insert symbols into the correct block (global, static, or a local
1519 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1521 (mipscoff_symfile_read): Don't call select_source_symtab.
1522 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1523 rather than SYMBOL_VALUE.
1524 (parse_external): Comment clobbering of top_stack.
1525 (parse_partial_symbols): Update comments. Allocate and parse
1526 static symbols as well as external symbols. FIXME, enum values
1527 are not handled in this pass, but should be. Inline new_psymbol.
1528 Use SYMBOL_VALUE_ADDRESS.
1529 (psymtab_to_symtab_1): Read symbols into global static block
1530 by default (until enter some function's local block context).
1531 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1532 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1534 * source.c (select_source_symtab): Select a source symtab
1535 from either the symtabs or, failing that, the psymtabs.
1536 (list_command): Update error message.
1537 (forward_search_command, reverse_search_command): Use getc, not
1538 fgetc, for speed. FIXME, add comment about buffers that die if
1539 overrun by long line.
1541 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1542 by an entire word, which is not portable, if we have a 32-bit
1543 field. (Code in dbxread.c already turns such bitfields, if
1544 aligned, into ordinary ints, but fixing this will help for other
1545 symbol formats and for future changes.)
1546 * core.c (core_open): Handle ANSI const brain death.
1547 * utils.c (vprintf): Fix varargs typo.
1549 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1551 * findvar.c (find_var_value): Handle &function better.
1552 * TODO: Document work needed on &fn and &array.
1553 * printcmd.c (print_address_symbolic): New arg is the prefix
1554 to print if a name is printed.
1555 (print_address_demangle): Honor "set print address" now.
1556 Use new arg above to improve spacing of output.
1557 * valprint.c (val_print): When printing function pointers,
1558 print symbolic form too.
1559 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1561 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1563 * core.c (memory_error): Reword error msg to mislead less.
1565 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1567 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1568 parse_partial_symbols): Use newer BFD internals (external_filehdr
1569 and external_aouthdr), byte-swap the fields that we care about
1570 before using them, and make the file header data local to
1571 read_the_mips_symtab rather than global.
1573 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1575 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1576 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1578 * main.c (command_line_input): Flush stdout and stderr
1579 before every call to readline. This reportedly fixes a bug
1580 that comes up in Sys V running emacs-gdb and/or xxgdb,
1581 when stdin/out are pipes or sockets.
1583 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1585 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1586 Avoid declaring Makefile dependencies, because GNU Make stupidly
1587 tries to update it if we do.
1589 * coffread.c: Revise for minor changes to bfd internal coff
1592 * configure: If -template= is given a relative path, make it
1593 absolute before recurring in subdirectories.
1595 * configure, configure.in, Makefile.in: Install "configure" script
1596 as replacement for config.gdb.
1597 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1598 * README: Update for configure, mostly. FIXME.
1600 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1601 target config files that they are for the host. When the lines
1602 get copied into the Makefile, this makes it more obvious what's
1605 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1607 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1608 tabs, which end up in the disassembler output inadvertently.
1610 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1612 Make it compile cleanly in an ANSI GCC2 environment.
1614 * blockframe.c: <stdio.h>
1615 * cplus-dem.c: free takes a void *, ifdef __STDC__
1616 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1618 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1619 * stddef.h, stdlib.h: Remove these files.
1620 * symtab.c: Avoid declaring qsort, close.
1621 * symfile.c: Avoid declaring close.
1622 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1623 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1625 Assorted other changes.
1626 * dbxread.c: include "libaout.h", not "liba.out.h".
1627 * printcmd.c (print_frame_args): Set recurse properly for
1628 indentation of struct and array parameters.
1629 * valops.c (value_cast): Allow cast to void.
1630 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1631 single_step() in a target-independent fashion.
1632 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1633 set up to be ready to continue. This makes us target independent.
1634 * infptrace.c (child_resume): Remove call to single_step; now
1635 can single step a SPARC target of any kind.
1637 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1639 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1640 docn into separate sections---basically chapters, plus two loose
1641 pieces that can be configured to go in different places. This
1642 allows GNU m4 to preprocess the manual without coredumping.
1644 * Makefile.dist: tell TeX where to find texinfo.
1646 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1648 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1649 the new target "rdl-apps.texinfo" which captures the Makefile
1650 variable that records where to find the Readline libraries.
1652 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1654 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1655 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1656 * defs.h (const, volatile): Only define if not already defined.
1657 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1659 * README: Update for release 3.95.
1660 * config.gdb: Don't create readline dir in subdir builds.
1661 * main.c: Include with "..." form for non-system include files,
1662 so "gcc -MM" for "make depend" works.
1663 Include readline files with "...h" rather than <readline/...h>.
1664 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1666 * coffread.c: Undo minor damage done by Rich Pixley. Use
1667 different internal and external representations of COFF
1668 data structures. Use new BFD routines for swapping them in and
1670 * symfile.c (free_named_symtabs): Avoid freeing file names that
1671 are null or empty. Old i960 tools seem to produce files that
1672 claim to have empty names, causing each successive file read
1673 to blow away the previous one.
1674 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1675 Move deferred_stores to top of file, but don't separate its
1676 #define's from its variable. Add commentary.
1677 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1678 favor of keeping the (working) config.gdb. Move readline
1681 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1683 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1685 * infptrace.c (fetch_registers): no result, since now void.
1686 * tconfig/news: target depends on m68k-tdep too.
1688 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1690 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1693 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1694 applied various small fixes due to or inspired by RMS comments
1696 * doc/gdb.texinfo: finished using all RMS comments, save those for
1697 appendices on readline and cmd history (which are in other source
1700 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1702 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1703 chapter 9; (2) documented 'break' command's menu mode for
1704 overloaded names, in response to hgs problem report C++ p-31
1706 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1708 * doc/gdb.texinfo: (1) better introductory example; (2) more
1709 consistent use of @code, @samp, @file, @kbd throughout; small
1710 cleanups to first three nodes; (3) new "Contributors" node;
1711 (4) Appendix, Renamed Commands; (5) divert specialized startup
1712 instructions to "Targets" chapter for generic manuals, while
1713 leaving them up front for manuals specific to specialized
1714 environments; (6) apply fixes from RMS comments through chapter 4.
1716 * pretex.m4: modify explanatory text slightly (and redefine
1717 "regexp") to keep GNU m4 from complaining. (It still crashes
1718 later, but one step at a time...)
1720 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1722 * readline/readline.c (update_line): Avoid dereferencing a pointer
1723 before comparing it to its bounds. Saber caught this.
1724 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1725 and only set PC if tgetstr returned non-null. Saber caught this.
1727 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1729 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1730 stuff for config manual) here where it counts; updated
1731 to use new subdir structure (gdb/doc/).
1733 * Makefile: generated from above via
1737 * gdbint.texinfo: added instructions on generating gdb.info* files
1738 locally for release. These are ordinary info
1739 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1740 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1741 to generate these, so we distribute them already formatted.
1743 * gdb.texinfo: included full Info node and menu crud (as generated
1744 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1746 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1747 put in comments-for-future gdb.info target (one day makeinfo will
1750 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1752 * gdb.texinfo: Updated to include new or old undocumented
1753 commands, at least the following (perhaps some others I forgot to
1754 record): info f, info float, info path, info program, info s, info
1755 set, info source, info terminal, info types, info user, set/show
1757 Also covered all recent GDB command renames for v4.
1759 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1761 * mipsread.c: Rather than keeping count of how many symtabs
1762 and psymtabs we have, for sorting purposes, count them when
1763 we need to sort. This fixes bug in rereading of symbol tables.
1765 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1767 * infcmd.c: renamed "info path" to "show paths"

1781 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1782 symtab.h, target.c, target.h: Lint.
1783 * core.c: setup and select frame after reading shared libs,
1784 else reading shared libs will clobber them. Lint.
1785 * utils.c (error): Force out any buffered wrap text.
1787 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1789 * remote.c: Remove decls of memory_insert_breakpoint
1790 and memory_remove_breakpoint, no longer used. (Suggestion of
1793 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1794 to make it easier to interface to "configure"'d libraries.
1796 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1798 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1799 aliases for set/show print.

1851 dc_dcontext_t not int.
1853 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1855 * coffread.c [TDESC]: Move setting of debug_info from
1856 coff_symfile_read to find_linenos and make it work with BFD.
1858 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1860 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1862 * utils.c (strsave): Make arg const char* not char*.
1864 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1888 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1889 (This still doesn't seem to make MIPS bkpts work.)
1890 * mipsread.c: Remove dup "Reading symbol data..." msg.
1891 (symbol_file_command, add_file_command): Remove, obsol.
1892 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1893 Wrap output appropriately.

1895 selected_frame rather than target_has_stack or coredumping.
1896 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1897 enums appropriately.
1899 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1901 * signame.c: Include defs.h and param.h.
1903 * cplus-dem.c: Include defs.h and param.h.
1904 Makefile.dist: Don't hack in the "param.h".
1905 param.h: Don't include defs.h.

1908 can have both ints and enum type_pieces in it.
1909 ({push,pop}_type_int): New functions.
1911 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1923 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1924 copying.awk, solib.c, inflow.c, symmisc.c
1925 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1926 Use {value_as,unpack}_pointer (added to values.c)
1927 not {value_as,unpack}_long on CORE_ADDR's.
1928 Use longest_to_int (added to defs.h) instead of cast to int.
1929 Remove from_tty arg to mod_path.
1930 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1931 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

1969 * xm-tahoe.h: Remove USE_OLD_TTY (not needed now that terminal.h
1970 includes sgtty.h before sys/ioctl.h).
1972 Sun Apr 28 22:04:47 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1974 * param-no-tm.h: Make BITS_BIG_ENDIAN defined to 0/1, not defined
1975 or not defined. Don't define it based on TARGET_BYTE_ORDER if

2404 (set_section_command): New command ("section xxx yyy" -- should
2405 be renamed to "set section xxx yyy" FIXME) which sets the

2442 Changes from Peter Schauer.
2444 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2446 * Make all file names fit in 14 characters (sigh and damn!):
2447 mv hp300hpux-xdep.c hp300ux-xdep.c
2448 mv symmetry-xdep.c symm-xdep.c
2449 mv symmetry-tdep.c symm-tdep.c
2450 mv convex-opcode.h convx-opcode.h
2451 mv tm-vxworks960.h tm-vx960.h
2452 mv tm-vxworks68.h tm-vx68.h
2453 mv Makefile.srcdir Makefile.sdir
2454 mv gdb-int.texinfo gdbint.texinfo
2455 mv remote-sa.m68k.shar rem-m68k.shar
2456 mv remote-multi.shar rem-multi.shar
2457 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2458 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2459 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2462 * command.c (user_info_1, user_info): New command for listing
2463 the user-defined commands.
2465 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2467 * dbxread.c (really_free_pendings): Clear file_symbols
2468 and global_symbols after freeing them; otherwise, running
2469 this function twice (if it appears twice on the cleanup
2470 chain), we try to free things twice.
2472 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2473 based on text_addr (the address of text in core), not on addr (the
2474 offset between text in the .o file and in core). This change
2475 is from Peter Schauer.
2477 * main.c: Define ALL_CLEANUPS as a cast of zero.
2478 (return_to_top_level): Use it.
2479 (main): Do all cleanups after each command run as part
2480 of the gdb startup sequence. Also do all cleanups before
2481 entering the command loop, and every time we exit the command
2482 loop and reenter. Before, the cleanups from the startup sequence
2483 were being left undone until the first error!
2484 (command_loop): Rename do_nothing cleanup to command_loop_marker
2485 so we can see it easily when examining the cleanup chain.
2486 (init_signals): Add another do_nothing for signal handling.
2487 (quit_command): Only try to kill target if it has execution.
2488 Problems in the target stack got us into a state where
2489 inferior_pid was nonzero but none of the targets had execution.
2490 In this state you couldn't exit gdb.
2492 * dbxread.c: Two changes from Peter Schauer.
2493 (echo_command): Fflush output after an echo command.
2494 (show_history): Pass all args to cmd_show_list.
2496 * utils.c (init_malloc): Call mtrace to turn on tracing
2497 if the environment variable MALLOC_TRACE is set to a file name.
2498 * mtrace.c: Add source file which provides a log of every malloc,
2499 free, and realloc to a trace file.
2500 * mtrace.awk: Add source file which analyzes the trace file.
2501 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2502 (VERSION): Roll to 3.94.3.
2504 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2505 (check_duplicates): Don't bother with watchpoints.
2506 (set_raw_breakpoint): Comment about danger of this routine.
2507 (watch_command): Parse and eval all args before calling
2510 * solib.c (find_solib): Avoid error in referencing memory to
2511 see if any more shared libraries have been added. This is
2512 particularly useful if the target has terminated. Bug reported
2515 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2516 in bringing up 3.94.2 on the Sun-3.
2518 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2519 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2520 expression (in scope) before reenabling watchpoint.
2521 * signame.c (init_sigs): Add missing declaration of i, fix
2522 sys_siglist declaration.
2523 * source.c (list_command): Fixed range computation to use
2525 * stack.c (backtrace_command): Do not allow command if target has
2526 no stack, print informative error message.
2527 * target.c (target_command): Do not write into command line
2528 because this fails if the target command is used in a user defined
2529 command. [This change was enhanced by gnu to support any-
2530 unique-prefix matching on target names.]
2531 * valops.c (value_struct_elt): Avoid infinite loop on an
2532 erroneous attempt to print the member of function (try p main.p).
2534 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2536 * expread.y (name_no_typename): Avoid reduce/reduce errors
2537 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2538 Since the GDB parser really doesn't use name_no_typename in a
2539 name-only context, the parser can't tell the diff between
2540 names and numbers here. Avoid allowing a name_no_typename
2541 to be a NAME_OR_*INT to resolve the conflict.
2543 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2545 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2547 * valprint.c (val_print_fields): bitfield printing didn't handle
2548 byte order. Indirect through a few more fns to cope.
2550 * values.c (modify_field): also cope with byte order.
2552 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2554 Cleanup for release 3.94.2:
2556 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2557 include files. Roll version to 3.94.2.
2559 * coffread.c (init_stringtab): Read length into unsigned char
2560 array before swapping; don't assume 32-bit longs.
2562 * target.c (target_info): Don't bother with get_sym_file, just use
2563 the symfile global variable.
2564 * symtab.h, symfile.c (get_sym_file): Delete it.
2566 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2567 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2568 (read_type): Replace one more error() with complain().
2570 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2572 * i960-tdep.c: Fix copyright attribution.
2574 * config.gdb: Quote all backquotes in doublequotes. You can
2575 quote me on that. BSD 4.4 shell found this one.
2577 * infptrace.c (throughout): The third argument to ptrace is an
2580 * infrun.c (wait_for_inferior): When program has terminated, we
2581 have to call target_terminal_ours before we pop that target off
2582 the stack (e.g. before a call to target_kill or
2583 target_mourn_inferior). This fixes problem where a program
2584 terminates, then GDB stops for (tty output) and you have to type
2585 "fg" to the shell to resume it. FIXME: This code for what to
2586 do after termination really should be in normal_stop instead.
2588 * gdbcore.h (read_memory_check): Change declaration; it changed
2591 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2592 4.4 prereleases, this avoids a bug in their sgtty compatability
2594 * remote.c: Use terminal.h rather than hand-rolling the same.
2596 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2597 * utils.c (strsave, strstr): Fix arg types.
2598 * valprint.c (val_print): lint
2600 MIPS symbol table support from Per Bothner:
2602 * symfile.c (symtab_fns): Remove initializer table that needs to
2603 be hacked for each new symbol file format supported.
2604 (add_symtab_fns): New function, chains symbol table
2605 handlers into the global list.
2606 (symfile_init): Search this list.
2607 * symfile.h: Add next pointer, declare add_symtab_fns.
2608 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2609 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2611 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2612 symbol *). Thus, we no longer need the hack to trash
2613 pst->filename. Good, since that hack confused code in symfile.c!
2615 (reorder_symtabs, destroy_all_symtabs): Removed static
2616 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2617 Instead, the latter now uses a temporary array (stack-allocated
2618 from an obstack, and then freed).
2620 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2621 haven't been set in the outermost stBlock of a procedure. This was
2622 a problem with f77 binaries on Ultrix 4.?.
2624 (new_symtab, new_symbol, new_type): Continue changing code to use
2625 obstacks more and otherwise conform to dbxread internal style.
2626 Made the free_code of symtabs be free_linetable (as in dbxread)
2627 instead of free_contents. This implies memory leaks when reading
2628 a new symbol table, until the conversion is finished. Did change
2629 (struct symbol) and (struct type) to be allocated on the
2630 symbol_obstack. Blocks and blockvectors are among the things
2633 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2634 tested much, but it solved one problem (reported by Meissner), and
2635 cleans up some other things. The problem happened when an
2636 included file contains actual code (functions) and not just
2637 definitions. The mips coff is a little inconvenient there, since
2638 it may cause a procedure to be mapped to the wrong psymtab.
2640 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2641 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2642 this will need work for the new core paradigm.
2644 Opcode patches from the net:
2646 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2647 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2648 missing altogether - they are added here. From Bruce Bauman.
2649 * mips-opcode.h: The low mask for C0 instructions was too small.
2650 From Garrett Lau. I modified the fix to check the entire 32-bit
2653 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2656 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2658 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2660 * dbxread.c (read_type): Pointer subtraction (value_sub in
2661 valarith.c) sometimes failed because the types of the
2662 pointers being subtracted were not identical.
2663 These differed because dbxread.c was allocating pointer types
2664 using dbx_alloc_type+smash_to_pointer_type instead of
2665 lookup_pointer_type. I failed to find a justification for the
2666 former, so I changed it to use the latter. Similarly, I
2667 replaced smash_to_function_type by lookup_function_type,
2668 and smash_to_reference_type by lookup_reference_type.
2670 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2671 _initialize_mipsread): corresponding changes.
2673 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2675 * source.c (mod_path): Do tilde_expand on each component of the path,
2676 rather than on the (list of) paths as a whole.
2677 (print_source_lines): Set first_line_listed in addition to
2678 current_source_symtab and current_source_line. If the source was
2679 not findable, after a "dir" command to fix the problem,
2680 a "list" would get the wrong lines.
2682 While I was there... (gnu):
2684 * dbxread.c (read_type): Change error to complaint.
2686 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2688 First attempt at detailed understanding of symbol table memory alloc.
2690 * dbxread.c (dbx_symfile_read): Free our string table if we
2691 aren't the mainline. Free the "info" struct since we're done with
2693 (init_psymbol_list): Free any previously allocated psymbol lists.
2694 (): FIXME: Should realloc-down the psymbol lists when done reading
2695 the main symbol file?
2697 * symmisc.c (free_symtab): Free fullname field too.
2699 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2700 (REGISTER_ADDR): Make result type unsigned int.
2702 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2703 define REGEX must also define REGEX1 (its dependency).
2705 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2707 * tconfig/i960: No longer works, points you at vxworks960 or
2710 * xgdb.c, XGDB-README: Remove file. Users can get the much
2712 * Makefile.dist: Remove all trace of xgdb.
2714 * breakpoint.c (breakpoint_1): Pass demangle arg to
2715 print_address_symbolic.
2716 (clear_breakpoints): Remove unused function.
2717 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2718 (breakpoint_re_set): Use catch_errors to do them all anyway.
2720 * gdb-int.texinfo (Host versus Target): Add section on what is
2721 a "host" feature versus what is a "target" feature.
2723 * infcmd.c (path_command, path_info): Handle the PATH variable
2724 (object search path) as conveniently as the source search path.
2725 * environ.c (set_in_environ): Set some vars in GDB's environment,
2726 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2727 * source.c (mod_path): New function, from guts of
2728 directory_command, modifies a path. Used by path_command.
2729 (directory_command): Call it.
2730 * defs.h (strsave): Declare.
2732 * utils.c (sevenbit_strings): Add new printing option.
2733 (printchar): Use it.
2734 (strsave): Provide this handy helper routine.
2735 (set_width_command): Rename set_screen_width_command.
2736 (_initialize_utils): "set screen-width" => "set width";
2737 "set screen-height" => "set height"; add sevenbit-strings.
2739 * infcmd.c (do_registers_info): Print floating point registers
2740 in raw hex as well as float format, regardless of whether it is
2741 a "virtual" convertible register.
2742 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2743 regs as a double, just in case it's being used that way.
2744 * values.c (unpack_long): Comment on array/function coercion.
2745 (unpack_double): Argument is in target byte order now. For
2746 integer arguments, just call unpack_long and float the result.
2747 * m68k-tdep.c: include defs.h for "const" handling.
2748 * remote-nindy.c: Use ieee-float stuff.
2749 (nindy_fetch_registers): Unpack double regs to host double, then
2751 (nindy_store_registers): Pack extendeds to host double, flip
2752 around by misusing unpack_double, send as target double.
2754 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2755 zero, as when stopped at the first instruction of a process.
2757 * blockframe.c: Fix filename in comment (param.h => tm.h).
2758 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2759 * tm-68k.h: Fix typos.
2761 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2763 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2765 * coredep.c (fetch_core_registers): Pass end-address of register
2766 section to register_addr as expected. Don't call supply_register
2767 if we'd just pass it garbage.
2769 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2771 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2773 * target.c (push_target, target_info): Cast enums to int for < or
2776 * stack.c (print_frame_info): Identify source file & line
2777 even if we can't print it.
2779 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2781 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2783 Clean up IEEE floating point support.
2785 * ieee-float.h: New file.
2786 * ieee-float.c: Write real routines to convert between host
2787 doubles and various target IEEE extendeds.
2788 * m68k-xdep.c: Eliminate assembler code for extended floats.
2789 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2790 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2791 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2792 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2793 double_to_ieee_extended.
2794 * i960-tdep.c: Define ext_format_i960.
2795 * m68k-tdep.c: Define ext_format_68881.
2796 * sparc-tdep.c: Define ext_format_sparc, though unused.
2797 * Makefile.dist (HFILES): Add ieee-float.h.
2798 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2801 Obsolete the "coffstrip" program in favor of using BFD's strip.
2803 * nindy-share/coffstrip.c: Remove file.
2804 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2805 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2806 * tconfig/nindy960: Remove reference to coffstrip.o.
2808 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2810 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2812 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2813 * dbxread.c: Remove static symfile_bfd.
2814 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2816 * inftarg.c (child_detach): Pop the child_ops vector if the
2817 detach is successful.
2818 * remote-nindy.c (nindy_create_inferior): Don't push a new
2819 nindy_ops since nindy uses the same one for execution and memory
2821 * core.c (core_ops): Use child_attach and child_create_inferior
2822 rather than default attach and create_inferior functions.
2824 Handle floating point registers in core files.
2826 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2827 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2828 This version untested since BFD doesn't yet support sun3 core
2830 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2831 conventions. Fix comments and style. This version has not
2832 been compiled yet, since we have no HP inhouse.
2833 * core.c (get_core_registers): Look for two sections, ".reg"
2834 and ".reg2", and pass both to fetch_core_registers sequentially.
2836 Revise directory path yet again.
2838 * source.c (forget_cached_source_info): Not static any more.
2839 (init_source_path): New default source path is "$cdir:$cwd".
2840 (dir_command): Handle variable arguments ($cdir, $cwd).
2841 (source_info): Print "Compilation directory" rather than
2842 "Originally compiled in" to remind people of $cdir.
2843 (openp): If the path contains $cwd, use current directory.
2844 (open_source_file): If compilation directory is known, replace
2845 first $cdir in path with the compilation directory.
2846 (print_source_lines): Even if we can't print the lines, set the
2847 current symtab and line for future commands like "info source" or
2848 "breakpoint". Also, error message now contains the file name,
2849 line number, and file access error message.
2850 (_initialize_source): Fix help text to describe changes.
2851 * main.c (cd_command): Forget cached source info when we chdir.
2852 * utils.c (strstr): Add simple implementation.
2854 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2856 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2857 Byte-swap COFF symbol tables if necessary when reading them in.
2858 Use complain() to replace error message in one spot. Needs
2859 corresponding change in bfd/coff-code.h to make some symbol
2860 swapping routines non-static.
2862 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2864 Merge changes from Eirik Fuller, for UTek.
2866 * defs.h (errno): Add declaration.
2867 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2868 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2869 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2870 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2871 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2872 declarations of errno.
2874 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2876 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2877 <rpc/rpc.h> and <rpc/types.h>.
2879 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2881 * i960-tdep.c (examine_prologue): Add new argument limit,
2882 which stops the scan at the end of the prologue, or at the PC.
2883 This fixes a problem where it walks down into the code for the
2884 user's statements if that code looks like function prologues.
2885 Mark Fox and I have been bouncing this code back and forth, making
2886 small changes to it. Callers changed to match.
2888 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2890 Cleanup for gdb-3.94 release final:
2892 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2893 the .c files from vx-share and nindy-share, from the various
2894 macros, since they are not found via ALLDEPFILES.
2895 (SFILES): Add tm-i960.h.
2896 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2897 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2899 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2900 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2902 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2904 * am29k-tdep.c: Add contribution line.
2905 (examine_prologue): Cache information about function prologues in
2906 the misc-function-vector to avoid lots of references over the
2907 serial line while examining instructions.
2909 * core.c (core_close): New function made from cleanup_core.
2911 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2912 remote-vx.c, remote.c, target.c, target.h,
2913 Update target_ops vector to add attach, close, and load entries.
2914 Use add_syms_addr_command, not add_file_addr_command, for
2915 add_file. Break out close routine from existing code.
2917 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2918 they are in an obstack.
2919 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2921 (define_symbol): Add symbol type parameter; change callers;
2922 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2923 it to influence the symbol class on the i960.
2924 (define_symbol): Swap LOC_CONST's into target byte order.
2926 * exec.c (exec_close): New function.
2927 (exec_file_command): Call it.
2929 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2930 Fix byte order of frame pointer.
2931 (read_var_value): Result of 0 if var's value can't be found,
2932 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2933 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2934 (locate_var_value): Use read_var_value and use its lazy address
2935 as the location of the var's value. Lint.
2937 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2940 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2941 obsolete Intel versions in favor of vxgdb versions.
2942 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2943 code dealing with byte order of values, which Intel did in host byte
2944 order rather than gdb-4's target byte order.
2945 (i960_frame_chain_valid): Move to nindy-tdep.c.
2946 (examine_prologue, skip_prologue, frame_find_saved_regs,
2947 frame_args_address, leafproc_return, saved_pc_after_call,
2948 pop_frame): Add vxgdb versions from Mark Fox.
2949 (examine_prologue, frame_struct_result_address): Add code
2950 to deal with the saved value of G13 (struct return address
2952 (frame_args_address): Modify Mark's version to prefer the
2953 saved value over the current value in the topmost frame.
2954 Cache result in the frame info to avoid performance hair in
2956 (print_fault): Add gdb960 code for printing faults.
2957 (_initialize_i960): Actually call check_host.
2959 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2960 add stub routines. FIXME, these currently just return zero!
2962 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2963 (attach_command): Call target_attach, not target_open, now.
2965 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2966 (child_attach): Rename from child_open.
2967 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2968 don't confuse it with a zero step_resume_break_address.
2970 * inftarg.c (child_detach): Eliminate inferior_pid test.
2971 (child_files_info): Clean up message a bit.
2972 (child_ops): Use child_attach, not child_open, to attach.
2974 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2975 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2976 findvar.c to here, since it depends on the contents of the
2977 shadow_contents of breakpoints, but keep if #if 0 since it is
2980 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2983 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2984 (ptype_command, display_command): Eliminate have_inferior_p and
2985 have_core_file_p in favor of target_has_stack or
2986 target_has_execution.
2987 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2988 code for actually finding the values of arguments, though we still
2989 keep track of the maximum stack offset for use in printing unnamed
2990 arguments. Handle missing FRAME_ARGS_ADDRESS.
2992 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2993 (struct nindy_regs): Define registers passed to/from nindy.
2994 (nindy_fetch_registers, nindy_store-registers): Translate between
2995 nindy and GDB formats for the registers.
2996 (dcache_init): Statically allocate the cache, since it was being
2997 allocated by a malloc that was never freed anyway.
2998 (nindy_create_inferior): Error, not core dump, if no exec file.
2999 (nindy_before_main_loop): Use target_load, not target_add_file.
3001 * remote-vx.c (net_load): Specify large timeout for load
3002 requests. Allow user to break out with INTERRUPT.
3003 (net_break): Remove useless code, clean up. Change callers.
3004 (parse-args, skip_white_space, find_white_space): Clean up arg
3005 parsing to cope with quoted strings.
3006 (net_wait, net_quit): Never call error, just return status.
3007 (vx_read_register, vx_write_register): Cleanup status checking.
3008 #ifdef the code based on which CPU we are using (960 or 68k),
3009 FIXME, this should be completely general but it isn't yet.
3010 (vx_xfer_memory, vx_resume): Cleanup status checking.
3011 (vx_run_files_info): Improve message.
3012 (vx_load_command): Renamed from vx_add_file_command. Allow load
3014 (net_ptrace): Remove unused routine.
3015 (vx_wait): Adopt code from vxgdb960 to cope with broken
3016 connections to target machine and prompt to disconnect. Remove
3017 debug printouts. Map some EVENT_'s to SIGnals.
3018 (add_symbol_stub, vx_open): Print names of object files we found,
3019 and "ok" if we read their symbols OK. Clarify output in general.
3020 (vx_attach, vx_detach, vx_kill): Add these commands.
3021 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3022 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3023 "info files" output, and create_inferior, since we already have
3026 * stack.c (frame_info): Replace Frame_unknown with 0.
3027 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3028 (return_command): Pop until the PC matches as well as the FP,
3029 so it works even if the FP is shared with another function,
3030 as in "frameless" or "leaf" procedures.
3032 * symfile.c (load_command): renamed from add_file_target_command.
3033 (add_syms_addr_command): renamed from add_file_addr_command.
3034 (add_syms_command): Stub to call target_add_syms.
3035 (_initialize_symfile): Change command names and descriptions,
3036 add-file => add-syms, and load from alias to its own command.
3038 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3039 maybe_kill_then_create_inferior): Default for attempts to start
3040 a process, if one is already running, is to ask about killing
3041 it and retry if yes.
3042 (upstack_create_inferior): #if-0 it, strata obsolete it.
3043 (push_target, unpush_target, pop_target): to_close() a target
3044 before unstacking it.
3045 (target_info): Renamed from target_files_info.
3046 (_initialize_targets): Rename "i files" as "i target", accessible
3049 * target.h: Improve comments about the target_ vectored routines.
3051 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3052 Convert commenting style to standard GNU style.
3053 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3054 (SKIP_PROLOGUE): No longer a no-op.
3055 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3056 (*_REGNUM): Sort register numbers.
3057 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3058 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3059 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3060 are now 10 byte extendeds, not 8 byte doubles.
3061 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3062 for nindy versus vxworks targets. FIXME, this should possibly go
3063 in the target vector.
3064 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3065 frame_saved_regs and arg pointer with each frame.
3066 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3067 (FRAME_ARGS_ADDRESS): Use cached result.
3068 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3069 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3070 (PRINT_RAMDON_SIGNAL): Call print_fault.
3071 (POP_FRAME): Now works.
3073 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3074 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3075 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3076 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3079 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3080 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3082 * valarith.c (value_subscripted_rvalue): Avoid handling
3083 floats and doubles specially; it gave alignment errors. Lint.
3085 * valops.c (value_of_variable, value_of_this): Error if unknown
3088 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3089 to avoid alignment problems.
3090 (value_print): Handle unknown value address.
3091 (cplus_val_print): Two args are ignored; remove them. Change caller.
3092 (val_print): Use unpack_long rather than pointer-deref.
3095 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3096 to avoid alignment problems.
3097 (value_being_returned): Error if return value unknown.
3098 (set_return_value): Add bogosity warning, FIXME. *
3100 * TODO: A woman's work is never done.
3102 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3103 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3104 Add ieee-float.o to OBS.
3105 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3106 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3107 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3109 Changes to generalize the VxWorks RPC protocol slightly, to handle
3110 i960 as well as 68000.
3112 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3113 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3114 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3115 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3116 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3117 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3118 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3119 so they will move in target byte order rather than network
3120 byte order (happens to be the same).
3122 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3124 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3126 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3129 Add contribution lines to various files, showing where they
3132 * breakpoint.c (break_insn, check_break_insn_size,
3133 read_memory_nobpt): Remove to mem-break.c.
3135 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3138 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3139 entry has bad register number. This change is not
3140 tested in this release, FIXME.
3142 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3145 * value.h: Force value's contents field to be aligned to hold
3146 at least a double or a long long (if supported). This avoids
3147 doing bcopy's in and out of the contents field.
3149 (step_1): Avoid coredump under obscure circumstances when we
3152 * symtab.h (misc_info): Add field to misc function vector for
3153 any kind of cached information the target code desires. AMD
3154 29000 uses this to avoid repeating examine_function_prologue's.
3156 * coffread.c: Lint. Remove static symfile, read_section_header.
3157 core.c (have_core_file_p): Lint: remove.
3158 expprint.c (print_subexp): Lint.
3159 infptrace.c, valops.c, valprint.c: lint.
3161 Roll in changes from vxgdb-5.0.1:
3163 * symtab.h: Comment byte order of each address class. Add
3164 LOC_LOCAL_ARG for frame-relative args (960).
3165 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3166 symtab.c, symmisc.c: ditto.
3168 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3170 * remote.c (remote_resume): Error if resume with a signal.
3172 * symfile.c (prim_record_misc_function): Clear misc_info.
3173 (fill_in_vptr_fieldno): Check stub type of arg.
3175 * valops.c (value_cast): Avoid looking up names of types whose
3176 name we don't know, to prevent coredump. Sun CC produces typedef
3177 rtx and the name of *rtx is zero...
3179 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3181 Roll in changes from final AMD 29000 port (Tiemann).
3183 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3184 for ../include/a.out.encap.h. This might not work now that BFD
3185 is separately compiled. Instead, BFD support for encap will have
3186 to translate machine type 29k into the right COFF_MAGIC.
3188 * infcmd.c: Remove references to inferior_pid that aren't used
3189 in actual ptrace calls; use target_has_execution, etc.
3190 (have_inferior_p): Remove function.
3191 (program_info): Print target info rather than "process number";
3192 avoid gratuitous messages unless from_tty.
3193 (run_stack_dummy, finish_command): Set proceed_to_finish.
3194 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3195 main.c: Lint. Lose have_inferior_p().
3196 inferior.h (have_inferior_p): Remove, lint.
3197 (proceed_to_finish): Add flag to ask that all regs be saved
3198 by normal_stop, for the few commands that need it, speeding up
3199 serial I/O. Add comments to stop_registers.
3201 * remote-eb.c: Remove newline from breakpoint message we grep
3202 for. Never time out when running the user program.
3206 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3208 Roll in changes from vxgdb-5.0.1:
3210 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3211 symbol in its raw form, we are processing an unlinked ".o" file.
3212 See if the target environment has assigned it an address, using
3213 target_lookup_symbol (VxWorks does), and enter it into the symtab
3216 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3217 68k versions for a simpler version that assumes zero FP at bottom.
3218 Fixes bug of truncated stack reports.
3220 * target.h (target_lookup_symbol): Define this routine's args
3221 and result, finally.
3223 * target.c (nosymbol): Default routine for target_lookup_symbol.
3224 (target_default): Default lookup_symbol and call_function too.
3225 (files_info): Only print has_all_memory warning if a non-dummy
3228 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3229 vx_convert_from_virtual): If target does not have floating point,
3230 zero register "values", and avoid doing cross-net conversions.
3231 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3232 (vx_open): Rearrange code that attaches to target and reads
3233 symbols for all loaded modules, to work if some of the modules
3234 are not accessible. Add symbol_stub() and add_symbol_stub()
3235 as callbacks from catch_errors(). Allow connect attempt to be
3236 interrupted painlessly with ^C (FIXME, there are still some bugs
3237 if the interrupt happens during symbol reading.). Print
3238 final message with puts_filtered, since symbol messages are
3243 * main.c (catch_errors): Only print errstring if non-null.
3244 (command_loop): Avoid an ioctl per command to test ISATTY.
3246 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3247 (vx_xfer_memory): Return correct result!
3248 (vx_files_info): Indicate whether target has float or not.
3249 (vx_lookup_symbol): Complain, not error, if target gone.
3250 (vx_open): Print "Connected" msg before disabling immediate-quit.
3251 [FIXME: lookup_symbol and vx_open changes need testing.]
3253 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3254 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3255 contributor lines and update copyrights to 1991.
3257 Changes from an attempted H-PUX host port:
3259 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3260 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3261 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3262 * remote-vx.c: include <sys/time.h> for HPUX.
3263 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3264 "core_file_command" routine to BFD regime. May not work yet.
3266 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3268 * xgdb.c: Replace X10 version with some VJ version.
3269 (FIXME: Its copyright assignment is not on record.)
3270 * xgdb.c: Update include files to X11R4 (Xaw crud).
3271 (xgdb_display_source, create_text_widget): fix call to
3272 get_filename_and_charpos. Rewack source window stuff for X11R4
3273 (gleaned from include files, and "nm's" of binary libraries, since
3274 I had no doc available).
3275 (append_selection, append_selection_word): Disable with FIXME
3276 since R4 changed interface here.
3277 (create_buttons): Add back the old set of buttons.
3278 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3280 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3281 Roll VERSION to 3.94 (not yet final though).
3283 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3285 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3286 obstack_int_grow, obstack_int_grow_fast): Eliminate
3287 cast on left of assignment, which gives MIPS cc fits and is
3290 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3291 F_ALIAS. Use printf, not fprintf, when not passing a file
3293 (compare_opcodes): Check that identical instructions have
3294 identical opcodes, complain otherwise.
3296 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3297 was reported by Roland McGrath.
3298 (unimp): Only match if exactly zero instruction. (Roland)
3299 (branches and traps): Generate all variations of these
3300 instructions with macros, based on a single call that defines
3301 each condition name and its binary representation.
3302 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3304 * valprint.c (val_print_fields): Take, and use, format parameter.
3305 This means that "p/x struct" again prints the elements in the
3306 desired format. Changed callers.
3308 * stack.c (frame_info): Use filtered output, and indicate wrap
3309 points. Remove kludgy formatting designed to avoid line wrap.
3311 * utils.c (wrap_here): If the line is already full (because
3312 we had printed a long indent or long wrapped string), do an
3313 immediate newline-and-indent.
3315 * m68k-pinsn.c (print_insn_arg): Bugfix from
3316 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3317 instruction is incorrectly disassembled as bkpt #8.
3319 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3320 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3321 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3322 and then will dump core (sometimes). I traced it back to an
3323 uninitialized symfile_name in psymtab_to_symtab.
3324 (const_vol_complaint): Add quotes to message.
3325 (define_symbol): Only believe line number if gcc_compiled.
3326 Avoid allocating symbol if we will not return it.
3328 Add target strata support so that newly established targets go
3329 into their right place in the target stack (e.g. a new exec file
3330 doesn't wipe out the ability to access the running process).
3332 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3333 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3334 and initialize it properly in all the targets.
3336 * target.h: Document strata. Change return type of push_target.
3338 * target.c (nomemory): new function for dummy memory access.
3339 (tcomplain): Rename complain, now also used in symfile.c.
3340 (push_target): Push targets within strata. New return value shows
3341 whether new target is on top of stack or not. Always keep dummy
3343 (target_files_info): Ignore dummy target.
3345 * core.c (core_open): Warn user, and skip accessing file, if the
3346 core target is not the topmost target in the stack.
3347 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3350 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3351 target_ops, it doesn't belong there since we have no regs there.
3352 Change name of target from machine => memory to clarify.
3354 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3356 * Freeze version 3.93 for release.
3358 * Makefile.dist: Handle vx-share and nindy-share subdirs
3359 properly when building gdb.tar.Z.
3361 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3362 printed in various places, so I could change just one copy.
3364 * dbxread.c, coffread.c: Change references to bfd->iostream
3365 to cast to FILE *, now that BFD avoids needing types defined
3366 in other header files.
3368 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3370 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3371 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3372 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3373 (actually gcc -Wall).
3375 * dbxread.c: Remove first_global_sym, last_global_sym, since
3376 they are never referenced.
3378 * defs.h (baud_rate): Declare.
3379 main.c: Define it, and add the -b option to set it.
3381 * gdb-int.texinfo: Add text on how to define a new host or target
3382 architecture, prompted by Per Bothner's questions about MIPS
3385 * gdb.texinfo: Document "complaints". Change doc of -q since
3386 gdb no longer prints the copyright and blurb if you specify a file
3387 name to be debugged (just like Emacs). Add doc for Nindy-specific
3388 command line flags for specifying target serial port and such.
3389 Update copyright to 1991.
3391 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3392 has taken over for us the job of ripping up executable files. The
3393 crud caused Per Bothner's port to not compile.
3395 * infrun.c (normal_stop): Avoid printing "Program exited
3396 normally" if we are in batch mode. This allows a GDB which
3397 executes a program on a target system, to behave like a Unix
3398 command (input from stdin, output to stdout, no extraneous
3401 * main.c (main): Allow additional machine-dependent command line
3402 options to be specified with the ADDITIONAL_OPTIONS,
3403 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3404 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3405 processing to occur just before the main loop with
3406 BEFORE_MAIN_LOOP_HOOK.
3407 (main): If a "core file" argument is specified, and it is not a
3408 core file, try it as a process ID to attach.
3409 (symbol_completion_function): Attempt to cope with
3410 "show screen-" TAB, not very successfully. This needs more work,
3412 (batch_file): New function, returns whether we are reading
3413 commands from an interactive tty on stdin, or from somewhere else.
3414 Called by normal_stop since it doesn't get from_tty passed down
3415 to it like many commands do.
3417 * remote-nindy.c: Handle command line options for nindy
3419 (nindy_before_main_loop): Prompt user for tty name if they
3420 don't specify it before getting to the interactive command loop.
3422 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3423 and -r command line options. Also add hook before main loop
3424 to make it easy to specify a tty.
3426 * TODO: More things to do, one done.
3428 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3430 * dbxread.c: Make complaint() calls pass pointer, not struct.
3431 Add complaints about badly formatted C++ type information
3432 (const/volatile indicator, and parse errors resulting in
3433 error_type). Fix C++ virtual member fn comment.
3434 (read_struct_type): Avoid bumping pointer if we got a parse
3435 error; this prevents our walking beyond the end of a string.
3436 Terminate loop on null char as well as semicolon.
3437 (process_one_symbol): Fix the LBRAC fix so that it uses the
3438 last previous SLINE, FUN, or SO record's PC address. C++ debug
3439 symbols did not have SLINE records in a useful order compared
3440 to the LBRAC records.
3441 (define_symbol): Handle "catch" records.
3443 * symtab.c (check_stub_type): Added new complain
3444 `stub_noname_complain' and added a consistency check to
3445 keep the debugger from crashing when finishing from an
3446 exception frame. A real fix will be needed later.
3448 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3450 * infcmd.c (attach_command): Make global.
3452 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3453 but make them easy to comment out. Perhaps later they should
3454 be enabled by what CPU you configure for? FIXME.
3455 (VERSION): Roll to 3.93.
3456 (pinsn.o): Remove rule for obsolete file.
3457 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3459 Run down a problem that manifested by printing the wrong function
3460 name in stack traces of read_ofile_symtab. Turned out that the
3461 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3462 the LBRAC symbol with an address in the *data* segment, which
3463 blew our binary search through the blocks.
3465 * dbxread.c: Use the complain() facility consistently to bitch
3466 about problems in the symbol file we are reading.
3467 (finish_block): Add code to check the nesting of the blocks;
3468 complain and Procrust them to fit if wrong.
3469 (make_blockvector): Check the order of the blocks, complain
3470 [but don't cope] if wrong.
3471 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3472 symbols to be sure their PC value is greater than the last SLINE
3473 (line number) symbol we've seen, complaining and adopting the
3474 SLINE PC value if wrong.
3476 * symfile.h (struct complaint, complaint_root, complain,
3477 clear_complaints): Add.
3478 * symfile.c (complain, complaint_root, clear_complaints): Add
3479 facility to deal with non-fatal complaints and to regularize their
3481 (symbol_file_add): Clear complaint counters to allow new complaints.
3482 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3484 * dbxread.c (dbx_symfile_read): Remember the address and size
3485 of the string table for the main symbol file, so we won't read it
3487 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3488 to avoid reading the string table yet again. Lint.
3489 (throughout): Improve filtered output, including word wrap.
3490 (read_range_type): Improve Bothner's fix to handle other types too.
3492 * utils.c: Improve line wrap implementation. Handle unlimited
3493 width by making chars_per_line unsigned.
3494 (puts_filtered): New, easy, function.
3496 * defs.h (puts_filtered): add.
3498 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3499 call the identical sort_symtab_syms() in symfile.c instead.
3501 * expread.y: Suggest the `file' command rather than `symbol-file'.
3503 * command.h (enum var_types): Add zinteger for seroable
3505 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3506 nested if's into a switch.
3508 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3509 we did not stop because of a breakpoint (it must have been for
3510 some other reason, like a "stepi"), so don't print anything.
3512 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3513 doesn't include <sys/types.h>, old SunOS's require it for
3516 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3518 A test port of gdb-3.92.6 to the Sony NEWS.
3521 Don't normally link in remote- or vx stuff.
3522 Some of it doesn't compile, and it wastes space for 99% of the users.
3523 Remove reference to no-longer-used HAVE_VPRINTF.
3524 Fixed BFD_DEP typo to BFD_DIR.
3526 Fix cast in arg to bfd_h_getlong.
3527 Make char *prefix be const.
3528 Fix how certain range types are mapped into builtin unsigned int types.
3530 Remove 2 #includes. They cause errors (on Sony, at least),
3531 and aren't needed (they wern't in earlier versions).
3533 print_address_symbolic should never demangle labels
3534 (since it prints *assembler-level* labels).
3536 [This was superseded by the change to printcmd below.]
3539 Add some "volatile" return types to avoid warnings.
3540 If MISSING_VPRINTF add vprintf function and not just macro
3541 (since vprintf is used in printcmd.c).
3543 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3544 (The latter isn't grokked by some PCC-based compilers.)
3546 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3548 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3549 * nindy-share/coffstrip.c
3550 Added some forward declarations (otherwise, gcc complains
3551 about implicit extern redefined as static).
3553 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3555 Changes inspired by Per Bothner:
3556 * printcmd.c (print_address_symbolic): Take additional parameter
3557 specifying whether to demangle.
3558 (print_address): Pass in asm_demangle to control demangling.
3559 (print_address_demangle): New fn, takes explicit arg to control
3561 * utils.c: Add new vars demangle and asm_demangle, and let them
3563 (fputs_demangled): If !demangle, just print the argument.
3564 (fprint_symbol): If !demangle, just print raw symbol.
3565 * valprint.c (val_print): Call print_address_demangle rather than
3566 print_address, to cause demangling to depend on the global
3567 rather than assembler-level demangling setting.
3568 * WHATS.NEW, gdb.texinfo: Document.
3570 * main.c (show_command): Show all settings if no arg.
3571 (initialize_main): Make "info set" the same as naked "show".
3572 * command.c (cmd_show_list): Handle prefix commands in the
3573 list, and print the name of the setting as well as its English
3574 description and value.
3576 Allow gdb functions to specify where a line should wrap if it
3577 exceeds the size of a terminal line. Use it to make the output
3579 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3580 of the right size when screen width changes.
3581 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3582 (wrap_here): New fn, indicates a point in the output where we
3583 should wrap the line rather than just letting it overflow at a
3585 (fputs_filtered): Implement wrapping.
3586 (n_spaces): New fn, returns a pointer to N spaces.
3587 (print_spaces_filtered): Use n_spaces.
3588 * defs.h (n_spaces): Declare.
3589 * stack.c (print_frame_info): Wrap with 4-space indent after
3590 fn name and before filename and line number.
3591 * printcmd.c (print_frame_args): Wrap with 4-space indent
3592 before each argument name is printed.
3593 * valprint.c (value_print): Wrap with no indentation before
3595 (val_print_fields): Wrap with indentation relative to nesting
3596 level before each field name.
3597 (val_print): Wrap with nesting indentation before array elements.
3598 * command.c (do_setshow_command): Avoid extra newlines,
3599 wrap with 4-space indent around values printed, end with period.
3600 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3602 * breakpoint.c (breakpoint_1): Implement addressprint for
3603 "info breakpoints" display. Change file name and line number
3604 format to " at file:nnn" rather than " (file line nnn)".
3605 * gdb.texinfo: Document.
3608 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3610 Frozen for gdb-3.92.6 release.
3612 README, WHATS.NEW: Update for 3.92.6 release.
3614 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3615 coffread.o from configs since it is now built by default.
3616 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3617 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3618 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3619 from configs since it is now built by default.
3621 Makefile.dist: Update for release 3.92.6. Handle files that
3622 have been moved to ../include, ../getopt, or ../bfd. Add
3623 saber.suppress and tests directory. Add config.status to
3624 the release (it will say "none").
3626 coredep.c: Minor formatting fixes.
3628 These changes were made in early December but only checked in now:
3629 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3630 nindy-share/nindy.c: lint
3631 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3632 register values coming back from the target; we store values
3633 in target byte order everywhere.
3635 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3637 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3639 * valprint.c (cplus_val_print, val_print_fields): New functions,
3640 which print C++ objects. They conspire to avoid printing a
3641 virtual base class more than once, following all the twists and
3642 turns of C++ virtual base rules.
3643 (val_print): Call the above rather than do it by hand.
3645 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3646 symbol file, not for added files like shared libs. This really
3647 needs to be generalized to a timestamp per file.
3649 * core.c (cleanup_core): Avoid coredump if no core file.
3651 * config.gdb: Accept -host or -target in place of +host or
3654 * coffread.c (find_linenos): Avoid desupported BFD interface
3655 to line numbers. We still read them manually rather than using
3656 BFD's "generic" features.
3658 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3660 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3662 * Makefile.dist: Eliminate use of $< in explicit targets.
3664 * readline/Makefile: Use $< rather than $*.c, which does not
3665 include the VPATH in GNU Make.
3667 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3668 copies of tconfig/i960, added for global configuration
3669 compatability. All i960 versions can read both coff and b.out.
3671 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3672 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3675 * TODO: Think of more things to do.
3677 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3679 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3680 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3681 64-bit float conversion.
3683 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3684 equivalent to sun?os4 so global config works.
3686 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3688 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3690 * main.c: Only declare linesize once; declare pagesize not at
3691 all, since it is never used.
3692 (main): Clear newly allocated line before it is used.
3694 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3696 Further stabilization for the Intel 960.
3698 * Makefile.dist: Parameterize the location of the "include"
3699 and "bfd" directories, as well as "getopt". Add symfile.c.
3700 Link in both dbxread and coffread. Fix up "make depend" to
3701 rewack the locations of include, bfd, and getopt in its output.
3703 * README: Document moving include files, improve some of
3706 * coffread.c: Move common code out to symfile.c. Change
3707 symbol_file_command style interface to use new *_symfile_init
3708 and *_symfile_read interface under BFD. Use BFD internal
3709 info to locate line table, symbols, etc.
3711 * core.c (core_fetch_registers): Rename to get_core_registers
3712 to avoid confusion with fetch_core_registers.
3713 (register_addr): Move to coredep.c, which is already machine
3714 dependent. This leaves core.c pretty clean of dependencies.
3716 * coredep.c (register_addr): Accept this routine from core.c.
3718 * dbxread.c: Move common code (with coffread.c, etc) into new
3719 symfile.c. Each psymtab now contains a pointer to the
3720 format-dependent function that knows how to read it in. Make
3722 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3723 (process_one_symbol): Add code to complain about a "compiler bug
3724 we muzzle here", if we actually see it.
3726 * eval.c (evaluate_subexp): Insert missing "break" statements
3727 in code that determines whether a variable is an lvalue in
3728 memory, register, or whatever. I detected this via a compiler
3729 bug in which it *almost* mashed out the whole switch statement.
3731 * gdb-int.texinfo: Add minor sections on configuring gdb for
3732 release, and about the README file.
3734 * infcmd.c (registers_info): Fix formatting somewhat. Still
3735 not as pretty as before, but it handles byte swapping.
3737 * remote-nindy.c: If data cache routines are interrupted while
3738 waiting for the remote end, be sure that any uninitialized cache
3739 blocks are on the free list, not on the valid list!
3741 * symfile.h: Flesh out this header file with all the various
3742 routines and variables that have been merged in from dbxread.c
3743 coffread.c, and symtab.c to symfile.c.
3745 * symfile.c: New file, containing code common to dbxread.c,
3746 coffread.c, and some code from symtab.c. All generic code for
3747 reading symbol files should be in here now.
3748 (unrecord_misc_function): Remove unused function.
3750 * symtab.h: Remove file-reading things to symfile.h.
3752 * symtab.c: Remove file-reading things to symfile.c.
3754 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3755 to decode i960 fault types.
3757 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3758 target.c: Change type of the "resume" function from int to void,
3759 since its result was never used.
3761 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3763 * main.c: Replace "stupid" with "caution"; you now "set caution
3766 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3768 * infcmd.c (do_registers_info): Call val_print to deal with the
3769 byte order of the registers being printed. FIXME, this makes
3770 the formatting of the output uglier.
3772 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3773 defined, call it for signals the debugger doesn't itself use.
3774 The i960 uses this for more detailed fault information.
3776 * remote.c (remote_open): If arg is null, print help rather than
3779 * sparc-xdep.c (register_valid): Avoid declaring size, since
3780 various modules will think of various sizes depending on the
3781 architecture of their tm-file. FIXME, we need protection against
3782 actually entering one of those modules, which would clobber
3783 storage if not for the target architecture compiled into gdb.
3785 * stack.c (up_command, down_command): Always print the frame
3787 (up_silently_command, down_silently_command): New commands
3790 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3792 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3793 more parameters than it used to.
3795 * findvar.c (registers): Increase slop to 256 bytes, which should
3796 protect us against even most RISC machines with large register
3798 (locate_var_value): Move declaration inside related ifdef.
3800 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3801 throughout, to avoid throwing away buffered input from the board.
3802 (nindy_wait): Supply_register takes addr_of_value, not value.
3803 (i960_print_fault): Renamed from i80960_fault.
3804 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3805 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3807 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3808 we can set the PC in the call to proceed(). Unpush nindy_ops
3809 before pushing it on top, to avoid message to user. Eliminate
3810 commentary from Unix machines that just misleads here.
3811 (reset_command): Fix error message to suggest target command.
3813 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3815 Release 3.92.5 as frozen.
3817 Stabilize the merged release...with help from lint, Saber C,
3820 Everywhere: Add include files needed to declare return types
3821 of functions called.
3823 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3825 * breakpoint.h: Add undeclared breakpoint functions, and some
3826 functions for display handling since I couldn't think of a better
3829 * breakpoint.c (insert_breakpoints): Make code for disabling
3830 shared library bkpts more likely to work. It's used when we
3831 rerun a program and stop before the shared library has been
3833 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3834 cast from pointer, so it squeezes through catch_errors.
3835 (bpstat_stop_status): Fix logic broken some time ago. We now
3836 always create a bpstat if the stop address matches a breakpoint,
3837 even if we don't stop there -- just like the old code used to do
3838 before I got my fingers into it (sigh).
3839 (breakpoint_1): Print "ignore count" after "stop only if"
3840 condition, since that's how it actually works.
3841 (mention): Handle watchpoints as well as breakpoints.
3842 (watch_command): use set_raw_breakpoint and mention to do most
3843 of the work (and initialize all the fields!). Only pass one
3844 arg to parse_c_expression, since that's all it takes.
3846 * command.c (not_just_help_class_command): Rename arg to args
3847 since we ignore "unused argument" warnings on vars named "args".
3848 inflow.c (child_terminal_info): ditto.
3849 infptrace.c (kill_inferior): ditto
3850 main.c (catch_errors, version_info, quit_command, pwd_command,
3851 source_command, dump_me_command, editing_info,
3852 set_history_size_command, set_history, show_history,
3854 stack.c (locals_info): ditto
3855 target.c (target_files_info): ditto
3856 valprint.c (set_input_radix, set_output_radix): ditto
3858 * core.c: Remove old variables for handling core and exec file
3859 sections (data_start, data_end, stack_start, stack_end,
3860 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3861 text_end, exec_data_start, exec_data_end, text_offset,
3862 exec_data_offset, data_offset, stack_offset). They're
3863 superseded the more general build_section_table and
3865 (get_exec_file): Mention the `file' command.
3866 (read_memory_check): Rename to memory_error, and only call it
3867 in the case of an actual error.
3868 (read_memory, write_memory): call memory_error.
3869 (core_fetch_registers): Register section name is ".reg".
3871 coredep.c: Remove a bunch of crud now that all this file does
3872 is pull the registers out of a core file.
3873 (fetch_core_registers): Rewrite to actually work, I hope.
3875 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3876 Replace index() with strchr(). Remove all the pre-BFD macro
3877 definitions for accessing the symbol file.
3878 (struct dbx_symfile_info): Encapsulate the information that
3879 dbx_symfile_init needs to pass to dbx_symfile_read in this
3882 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3883 dbx_symfile_discard): Rearrange symbol file reading to divide
3884 the format-specific part from the format-independent part,
3885 leaving the format-independent part such as file name expansion
3886 and opening in symtab.c. This replaces
3887 partial_symbol_file_open and partial_symbol_file_read.
3888 Symbol_file_read, add_file, add_file_target_command,
3889 add_file_addr_command move to symtab.c. Pass an explicit
3890 "mainline" flag for when reading the main symbol table, rather
3891 than relying on the offset address to be zero or nonzero.
3893 (dbx_symfile_read): Don't allow void *'s to be printed as
3895 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3896 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3897 macro" debug version really work.
3898 (read_dbx_symtab): Remove unref'd parameter inclink.
3899 Avoid swapping N_SLINE symbols, for speed.
3900 Merge N_TEXT!N_EXT case with the other external symbol
3901 definitions' case. Add comments.
3902 (start_psymtab): Allocate the symfile name in the psymtab on
3903 the psymbol_obstack, rather than using the caller's storage.
3904 (end_psymtab): Only allocate a dependencies list if there are
3906 (psymtab_to_symtab_2): Use BFD when reopening file to read
3907 its symbols for real.

3910 (read_huge_number): Add FIXME about overflows.
3911 (read_range_type): Add FIXME about comparing a long to 1<<32.
3913 * coffread.c: Minor changes to move things closer to the new
3914 regime with symtab.c and dbxread.c Major work is still needed
3917 * exec.c (exec_file_command): Remove old variables (see core.c
3919 (xfer_memory): If memory transfer is right at the end of a
3920 section, don't lose.
3922 * findvar.c (get_saved_register): If value is in a real
3923 register, LVAL is lval_register, not lval_memory.
3925 frame.h: Declare print_sel_frame and record_selected_frame.
3927 gdb-int.texinfo: New file, for GDB internals documentation.
3928 Very simple, unformatted doc of cleanups is there for now.

3931 section addresses and offsets. (See core.c above.)
3932 Declare fetch_core_registers and registers_fetched.
3934 getopt.c: Declare char *alloca(); even on SPARC.
3936 infcmd.c (run_command): Call target_kill rather than
3938 (step_command, next_command, stepi_command, nexti_command):
3939 Declare from_tty parameter even though we don't use it.
3940 (run_stack_dummy): argument BUFFER is a char array, not
3941 a pointer to REGISTER_TYPE.
3942 (finish_command): using_struct_return needed a value *,
3943 not a struct symbol *.
3945 * infptrace.c (child_xfer_memory): To avoid dependency on
3946 where sections are in memory, try PT_WRITE_D and if that fails,
3947 try PT_WRITE_I. Most Unixes don't care which you use.
3949 * infrun.c (step_resume_break_shadow): Change to array to
3950 match other breakpoint shadow storage.
3951 (clear_proceed_status): Pass address of bpstat to
3952 bpstat_clear, not the bpstat itself.
3953 (child_create_inferior): FIXME comment about if the child
3955 (start_inferior): Remove old function.
3956 (child_open): Use target_kill rather than kill_inferior.
3957 (wait_for_inferior): Ditto.
3958 (insert_step_breakpoint, remote_step_breakpoint): Use
3959 new step_resume_break_shadow.
3961 * inftarg.c (child_wait): If all child processes die,
3962 pretend that the one being waited for exited with signal 42.
3964 * main.c (command_line_input): When scanning for comments,
3965 don't coredump on unclosed quotes.
3966 (quit_command): Use target_kill rther than kill_inferior.
3967 (_initialize_main): Rename class_user from "user" to
3970 * printcmd.c (print_command_1): Initialize "fmt" if no format
3971 is specified by the user.
3972 (print_frame_args): Only add to args_printed if we are
3973 actually fetching args from the stack (avoiding undefined
3975 (_initialize_printcmd): Remove bogus \{ from string.
3977 * remote-eb.c (eb_open): Avoid coredump on no argument.
3979 * remote-nindy.c: Bring out of Intel environment into new
3980 target environment. Remove all conditional compilation on
3981 I80960. Massive hacking throughout.
3982 (nindy_xfer_inferior_memory): New routine stolen from
3984 (nindy_create_inferior): New routine pieced together, probably
3985 not quite working yet.
3986 (nindy_ops): New target_ops struct for nindy.
3988 * remote-vx.c: Use write_memory rather than target_write_memory
3989 to get error checking.
3990 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3992 (vx_create_inferior): Use target_terminal_ours...
3994 * signame.c (_initialize_signame): Always initialize, since
3995 we need the table for things other than psignal.
3997 * solib.c (solib_add): Use symbol_file_add, not add_file.
3998 (solib_address): Return boolean result rather than struct
3999 pointer which nobody else knows the type of.
4001 * sparc-tdep.c, valops.c: Use write_memory rather than
4002 target_write_memory, to get error checking.
4004 * stack.c (locals_info, catch_info, args_info,
4005 get_selected_block, frame_command, up_command): Use
4006 target_has_stack, rather than have_inferior_p or
4009 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4011 * symfile.h: New file, defining the interface between the
4012 generic and object-file-specific symbol reading code.
4014 * symtab.c: Move generic symbol-reading interface to symtab.c,
4015 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4016 table to map BFD targets to symbol-reading modules in GDB.
4017 Change index to strchr.
4018 (lookup_struct_elt_type): Use error() rather than hand-made
4019 simulations thereof.
4020 (lookup_partial_symbol): Speedup slightly when length == 0.
4021 (symbol_file_add): New function.
4022 (symbol_file_command): Call it.
4023 (symfile_open, symfile_init): New function.
4024 (add_file_target_command, add_file_addr_command): moved from
4027 * target.c (target_command): use target_kill.
4029 * target.h (target_files_info): Don't declare, never called
4032 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4033 files to determine stack end address.
4035 * valarith.c (value_x_binop, value_x_unop): Change error message
4036 to be more useful. Pass proper argument to value_struct_elt.
4038 * valops.c (value_assign): FIXME comment that long long
4039 bitfields will break here.
4041 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4042 Update `make saber_gdb' to work better.
4044 * TODO: A woman's work is never done.
4046 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4047 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4048 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4049 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4050 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4051 valops.c, valprint.c, exec.c: Lint.
4054 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4056 Continuing Intel 960 port merge of GDB.
4058 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4059 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4060 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4061 Wack over "make depend" so it handles files in subdirectories
4062 vx-share, nindy-share, bfd, and in the current directory.
4064 * blockframe.c (get_prev_frame_info): Remove fatal error
4065 if stack not defined.
4067 * core.c (core_open, core_detach): New functions that handle
4068 the old "core-file" command as "target core" and "detach" instead.
4069 (core_file_command): Call them.
4070 (core_xfer_memory): Use common routine xfer_memory.
4072 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4073 dbxread now uses bfd for everything but symbol reading itself.
4074 BFD internals are used to drag out the relevant file offsets.
4075 (partial_symbol_file_open): Change args all around for BFD.
4077 * symtab.c: Rename "value" to "val" everywhere, so we can
4079 (symbol_file_command): New command, moved from dbxread.c
4080 and coffread.c. It uses BFD to read the file, then vectors
4081 based on its type, to dbx or coff symbol readers.
4082 * symtab.h: Extern a few vars for symbol_file_command.
4084 * target.h: Breakpoint takes a char * save area, not a char **.
4086 * valprint.c (val_print): When unpacking bitfields, offset
4087 the address in gdb of the value, if it is declared with a shorter
4088 type. Remove the last "runtime kludge test" of host byte order.
4090 * utils.c: Remove old my_bfd_read routine.
4092 * stack.c (frame_info): Use target_has_stack. Print program counter
4093 register's actual name rather than "pc", since it's called the
4094 "ip" (instruction pointer) on the i960 (sigh).
4096 * target.c (target_command): Add command for selecting a target
4097 type and calling its open routine. This is used for initiating
4098 communication with a particular target, in a generic way.
4100 * tm-i960.h: Update for modern gdb. Remove semicolons from
4101 various macros. Handle reading struct return convention, and
4102 error-out attempts to return structs with the "return" command.
4103 Be sure gdb doesn't think we know how to call functions in the
4106 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4107 to i960_xxx in lower case.
4108 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4109 not being defined yet.
4111 * remote.c (remote_open): Call start_remote to initialize
4112 wait_for_inferior during open.
4113 (remote_xfer_inferior_memory): Return length written rather
4116 * remote-vx.c (target_command -> vx_open): Use new generic
4118 * remote-eb.c, inftarg.c, exec.c: ditto.
4120 * infrun.c: Fix comments.
4121 (attach_program -> child_open): Use new generic target command.
4122 (wait_for_inferior): Clear saved register values before target_wait,
4123 so target_wait can set some of them if convenient.
4125 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4126 Return success indicator, not void.
4127 (child_xfer_memory): Avoid fetching initial word if we'll
4128 overwrite it anyway.
4130 * infcmd.c (attach_command): Use new generic target open routine.
4131 (_initialize_infcmd): Update doc on attach and detach commands.
4132 (do_registers_info): Merge in a byte-order problem as a FIXME
4135 * findvar.c (find_saved_register): Avoid problem in current frame.
4136 (read_relative_register): Ditto.
4137 (write_register): Convert byte order on the way out.
4139 * exec.c (file_command): Add.
4140 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4141 (xfer_memory): Common function between core_xfer_memory and
4143 (exec_xfer_memory): Use it.
4145 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4147 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4148 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4149 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4151 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4153 Merge Intel 960 port of gdb, continuing...
4155 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4156 symbol_file_command): Pass from_tty arg to hush 'em up.
4158 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4159 Add magic numbers for 960 COFF format.
4161 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4163 Merge Intel 960 port of gdb, from Intel "1.2" release.
4165 CHANGE_LOG entries from their port, which was based on
4168 Thu Sep 6 11:02:22 PDT 1990
4169 Remove temp file if download is interrupted.
4171 Wed Aug 1 09:08:33 PDT 1990
4172 Now uses binary protocol to talk to NINDY.
4173 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4174 Times out after 5 seconds when trying to talk to NINDY.
4176 Tue May 29 12:54:49 PDT 1990
4177 Added variable baud rate (-b switch).
4178 Source code reorganization.
4180 Thu Apr 26 11:09:55 PDT 1990
4181 More cleanup of batch mode; specifically, execute "-s", "-e", and
4182 "-se" switches as soon as they are encountered on the invocation line.
4184 Fri Apr 20 13:47:15 PDT 1990
4187 Thu Apr 19 09:54:28 PDT 1990
4188 Add 'reset' command.
4190 Wed Apr 18 09:48:07 PDT 1990
4191 After opening remote tty, wait for 1 second to go by without input
4192 from it before trying to talk to NINDY (fixes problems with the
4193 Heurikon HK80/V960E).
4195 Mon Apr 4 16:33:05 PDT 1990
4196 Some output was not being suppressed in 'batch' mode.
4198 Thu Mar 22 15:31:11 PST 1990
4199 Ask user if old symbol table should be deleted when new file is
4202 Allow user to run a program downloaded before gdb960 was brought up.
4204 Correct "exec-file" help message for i80960 context.
4206 Correct bug in calculating user space address: could occasionally
4207 corrupt user program.
4209 Make sure to zero low-order bits in rip's because of bug in 960CA
4210 A-step part: could cause operation faults when "next"ing across
4213 Correct bug that made it impossible to get source line numbers for
4214 code loaded at addresses higher than 0x7fffffff.
4216 Wed Jan 10 12:43:22 PST 1990
4217 Open remote tty for exclusive use.
4219 Fri Jan 5 12:14:42 PST 1990
4220 Correct disassembly (CA manual was right after all):
4221 opcode for sysctl is 0x659
4223 Mon Oct 23 12:03:04 PDT 1989
4224 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4226 Mon Oct 16 14:15:09 PDT 1989
4227 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4229 Mon Oct 2 15:56:31 PDT 1989
4231 Added 960CA disassembly support.
4233 To simplify maintenance:
4234 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4236 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4237 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4238 - made disassembly interface identical to that in gdmp960.
4242 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4244 * target.h: Allow targets to stack. Add target_has_memory,
4245 _registers, etc. Restructure memory access and "info files"
4246 to walk the target stack.
4247 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4248 target.c: Change tables to match target.h.
4249 * inflow.c (child_mourn_inferior): pop child_ops.
4250 (generic_mourn_inferior): Use new has_stack flag.
4251 * infptrace.c (child_xfer_memory): New memory regime.
4252 * inftarg.c (child_files_info): New "info files" regime.
4253 * remote-eb.c: New memory regime, new info files.
4254 * remote-vx.c: New memory regime, new info files. Now use
4255 separate targets for VxWorks attachment to machine, and
4256 actually running a process under VxWorks, since one has
4257 stack & execution & regs and the other doesn't.
4258 * remote.c: New memory regime, new info files.
4259 * sparc-xdep.c (fetch_core-registers): New memory regime.
4260 * target.c: New routines and support for stacked targets,
4261 new memory regime, new info files regime.
4264 Generalize section handling for an arbitrary number of sections,
4265 including use of the new BFD (binary file) library.
4266 * gdbcore.h: Add struct section_table.
4267 * exec.c (build_section_table): Iterate all sections and
4268 record what gdb needs to know about them.
4269 (exec_command): Use it.
4270 (exec_xfer_memory): Use the table.
4271 (exec_files_info): Print the table.
4272 * core.c (core_file_command, core_xfer_memory, core_files_info):
4274 * source.c (find_source_lines): Use bfd_get_mtime.
4275 * dbxread.c: Quick changes to make it compile with new BFD.
4276 * utils.c (error): Avoid using bfd_error in generic routines.
4278 * core.c (core_fetch_registers): Get from the ".regs" section of
4280 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4282 * inferior.h (attach_flag): Export.
4283 * infcmd.c (run_command): use new target_create_inferior.
4284 * infrun.c (child_create_inferior): Don't return result.
4285 * Makefile.dist (VERSION): 3.91.4.
4287 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4289 * breakpoint.c (bpstat_num): Handle breakpoints which have
4290 since been deleted, such as temporary breakpoints.
4291 infcmd.c (program_info): ditto.
4293 * core.c (core_file_command): Display the frame where the core
4298 * remote-vx.c (target_command): Merge in target command from
4299 targ-vx.c. A few other cleanups.
4301 * TODO, Projects: Lots more stuff to do...
4303 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4305 Massive changes to wall off the remote-debugging interface
4306 behind a function vector. The port to handle VxWorks targets
4307 is also part of this.
4309 All files: Replace references to renamed functions,
4310 remove references to remote_debugging, remove references to
4311 have_include_file, have_core_file in favor of target_has_stack,
4312 target_has_memory, etc.
4314 * Modularize the breakpoint interface.
4315 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4316 a breakpoint instruction.
4317 breakpoint.c: struct breakpoint's shadow_contents now sized as
4319 (insert_breakpoints): Vector to target to install breakpoints.
4320 (remove_breakpoints): Vector to target here too.
4321 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4322 sparc-tdep.c (single_step): Use new breakpoint interface for
4323 the single-step breakpoints.
4324 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4325 New file, contains routines to insert and remove breakpoints by
4326 reading out the old contents and later replacing them. This is
4327 how ptrace breakpoints work, and many remote systems as well.
4329 * tm-vxworks68.h: New config file, overrides a few things for
4330 Wind River's preferences.
4332 * target.h: New file, for transfer vector used to talk to the
4333 inferior (child, attached, core, exec, remote, etc). All accesses
4334 to the thing being debugged should come through these vectors.
4335 target.c: New file, routines to handle transfer vector.
4336 (various files): Add transfer vectors XXX_ops for the various
4337 targets and pseudo-targets (core files, etc) we support.
4339 * breakpoint.c (bpstat_stop_status): Further explorations of
4340 watchpoints and why things don't work all the time.
4341 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4343 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4344 the local gdbinit if it doesn't already have it.
4346 * core.c (core_ops): add and install.
4347 Allow core debugging without exec file.
4349 * dbxread.c (free_and_init_header_files): Merge two fns.
4350 (end_symtab): Free named symbol table when a new version comes in.
4351 (read_dbx_symtab): Relocate all kinds of symbols with base
4352 address. First step toward handling different text, data, bss
4354 (add_file_addr_command): Renamed add_file_command.
4355 (add_file_command): Vector to remote handler.
4356 Add "load" as an alias for "add-file" command.
4358 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4359 non-returning functions.
4361 * exec.c: Add exec_ops, and push it as a target when an exec
4364 * infcmd.c (run_command): Pass executable file name and arg list
4365 separately when starting an inferior. Permit "run" when no exec
4366 file is specified, for VxWorks.
4367 (detach_command): Move to child_detach in inftarg.c.
4369 * inftarg.c: New file. Unix-child-specific routines, and the
4370 child_ops structure.
4372 * inferior.h (registers): Export "registers" as the way for
4373 target dependent register handlers to find gdb's local copy of
4374 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4375 since it is now used by places that want wait_for_inferior to
4376 handle the grunge but want to see every trap from the inferior.
4378 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4379 Eliminate remote_debugging hooks in terminal handling.
4381 * infrun.c: Replace start_inferior with child_create_inferior.
4382 Move all the hair of Unix shells and ptrace idiosyncracies into
4383 child_create_inferior, so remote handlers don't have to deal.
4384 Remove running_in_shell. Rename stop_after_attach to
4385 stop_soon_quietly, and use it in a few other places where we want
4386 to just call wait_for_inferior and get control back on the first
4387 trap. trap_expected now never takes a value > 1.
4388 (init_wait_for_inferior): Initialize static vars when a new
4391 main.c (gdbinit): Add new hook for .gdbinit file name, let
4392 it be overridden by config files as GDBINIT_FILENAME.
4393 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4394 Both of these are used for VxWorks gdb.
4396 mcheck.c: rename include file "gmalloc.c" to avoid problems
4397 with system include file "malloc.c".
4399 param-no-tm.h: New include file, same as param.h but does not
4400 include the default "tm.h" file. This is used in files where
4401 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4403 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4405 remote-vx.c: New file, VxWorks remote debugging support. Uses
4406 RPC routines that are shared with the target system, in directory
4409 remote.c: Vectorize remote interface.
4411 source.c: Globalize source_path, and make an alias "l" for "list"
4412 since we now have the "load" command.
4414 sparc-xdep.c: Use new param-no-tm.h.
4416 symmisc.c (free_named_symtab): Add new function from Wind River.
4417 However, ifdef it out for now while we think about what it should
4420 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4422 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4423 non-Unix-children handle this with their own code in the target
4426 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4427 source and target lists. Add vx-share to default list of include
4428 directories. Add new files to src and target lists: mem-break,
4429 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4430 ${srcdir} versions of munch and createtags are used.
4432 * valops.c (find_function_addr): Split out of call_function.
4433 (call_function_by_hand): Rename call_function; this function
4434 calls functions in the target by laboriously patching the target
4435 word-by-word with the right stack, args, regs, etc.
4438 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4440 Handle AMD 29000 a bit better.
4442 * remote-eb.c (readchar): Mask received char log to make it readable.
4443 (remote_start): Pass arguments down to executing program.
4444 Make startaddr unsigned.
4445 infrun.c (start_inferior): Accept args, pass them to
4447 infcmd.c (run_command): Pass args down to start_inferior.
4449 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4450 the target object file format.
4451 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4453 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4454 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4456 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4458 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4459 * TODO: We did a few things, we have more to do though.

4462 * inflow.c (inferior_died): Clear deferred stores.
4464 * Debug problems with dummy frames and calls to the inferior.

4466 * sparc-tdep.c (do_restore_insn): Simplify.
4467 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4468 (sparc_push_dummy_frame): Simplify and fix what we push.
4469 (sparc_pop_frame): Slightly more hair here, deciding whether
4470 we are restoring a saved PC or returning to a return address in %i7.
4471 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4473 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4474 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4475 * obstack.h (chunkfun): ditto.
4476 * defs.h (xmalloc, xrealloc): ditto
4478 * utils.c (quit): Grab the terminal from the child if necessary.
4480 * inflow.c (term_status_command): Rename to term_info, change
4483 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4484 (is_delayed_branch): Speed up.
4485 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4486 Still missing some float ops, and needs testing.
4488 * Support for input and output radixes other than base 10
4489 * defs.h (input_radix, output_radix): Declare.
4490 * expread.y (yyparse, parse_number): Handle changes of input
4491 radix, and ambiguous names-or-numbers in radixes >10.
4492 * printcmd.c (print_scalar_formatted): Print formatted hex
4493 numbers in varying column widths.
4494 * valprint.c (val_print): Use output_format to print scalar ints.
4495 (set_input_radix, set_output_radix, set_radix): Create.
4496 (set_output_radix): Set output_format from output_radix.
4497 (_initialize_valprint): add `set radix' but leave the others off.
4499 * main.c (execute_command): Let stupid questions be turned off.
4500 (_initialize_main): Handle "set stupidity", etc.
4502 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4503 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4505 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4507 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4508 bfd stuff is still screwed up, but with some manual work, it
4511 * breakpoint.c (bpstat_do_actions): Start over if a command
4512 proceeds the inferior, since the inferior will have stopped and
4513 will need to have its new stop-actions taken care of.
4515 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4516 compiler fits, simplify it.
4518 * gdb.texinfo (directory command): Doc new dir command.
4519 source.c (directory_command): "dir" now puts things on the front
4520 of the path, moves dups up front, and handles multiple names
4521 on the command line, inserting each one in order. It also
4522 blows away cached line and full_filename info.
4524 * stack.c (backtrace_command): Skip "more stack frames follow"
4527 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4528 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4529 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4530 The only odd one was Gould NP1, which had defined vprintf to
4533 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4534 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4535 variable, inspect_it.
4536 valprint.c (print_string, val_print): Use the global inspect_it
4537 to indicate whether to print in Epoch style or normal style.
4539 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4541 * printcmd.c (call_command): add an alias for the "print" command
4542 which runs expressions and doesn't print the result if void.
4543 (print_command_1): implement it.
4545 * command.c: Remove #if 0'd code. Initialize all the fields
4546 in add_cmd (). Rename do_nothing_command to
4547 not_just_help_class_command, and make it externally visible.
4548 command.h: add user_commands to struct.
4549 * main.c (define_command): Don't overload c->function with a char
4550 string as well as a function pointer.
4552 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4553 calling convention of value_struct_elt () that got dropped in
4556 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4557 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4559 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4561 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4562 until a good time (e.g. when we are about to run the child),
4563 saving ptrace calls.
4564 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4565 * tm-sparc.h: define DO_DEFERRED_STORES.
4567 * sparc-xdep.c (store_inferior_registers): when storing float
4568 registers, don't store stack regs too. When storing the SP,
4569 however, DO store the stack regs too. This fixes a bug in which
4570 the dummy frame is not recognized when a call_function finishes,
4571 because its frame pointer (in the stack regs) was never
4573 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4574 even though we don't know how to read them from an inferior.
4575 valops.c (call_function): Comment about storing SP.
4577 * infrun.c (save_inferior_status): Save away the original bpstat
4578 chain so it can be restored later. Install the copied version for
4579 use by whoever saved the status. It will be blow away by
4580 restore_inferior_status, and the original chain restored. This is
4581 important for people who have pointers into the original.
4583 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4584 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4585 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4588 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4590 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4591 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4592 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4594 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4596 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4597 Store the baseclasses in a type struct starting from array element
4598 0 rather than from the unusual array element 1.
4600 dbxread.c: the above.
4601 (virtual_context): Add
4602 Read new debug information about which virtual function table
4603 a virtual function is from, and store it in fn_field.fcontext.
4605 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4606 TYPE_FN_FIELD_STATIC_P.
4608 symtab.c: the above.
4609 valops.c: the above. Handle pointer casts of object *'s.
4610 (search_struct_method): Add.
4611 (value_struct_elt): First arg is now a pointer to a value, and is
4614 valprint.c: the above.
4615 values.c (value_virtual_fn_field): Add type arg. Handle
4616 offsetting to the proper object when calling virtual fns.
4618 (baseclass_addr): Add valuep arg.
4620 * README: Document the current state of BFD config (missing).
4621 * TODO, ChangeLog, Makefile.dist: Roll version.
4622 * WHATS.NEW: Add summary of changes since 3.5.
4624 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4626 * dbxread.c (read_struct_type): Clear bit vectors whenever
4628 symtab.c (B_CLRALL): define.
4630 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4631 using == rather than =. Huh... This fixes the dreaded problem
4632 wherein builtin_type_int becomes TYPE_CODE_FLT.
4634 * core.c (info_files): Show the inferior pid.
4636 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4637 already knows how to look in the source directory.
4639 * Remove psymtab hair from many places. Remove duplicated code
4640 for searching symbol tables. Hide psymtabs from most places.
4641 Make it fast to get from a psymtab to its symtab.
4643 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4644 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4645 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4646 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4647 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4648 new symtab completely. New psymtabs get symtab pointer
4649 initialized to zero. Remove MI warning printf.
4650 symtab.h: Comments. Add psymtab to symtab pointer.
4651 (PSYMTAB_TO_SYMTAB): New macro.
4652 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4653 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4655 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4657 (print_frame_info): Avoid special-casing symbols that have not yet
4660 * source.c (open_source_file): Quick path if we have already
4661 located the source file by its full name.
4663 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4664 find_pc_psymtab. When a name is found in the misc function
4665 vector, search the symbol table for its mangled name, not the
4666 name that the user typed.
4668 * bfd.h: Fix missing comment terminators, make #endifs match.
4670 * valarith.c (value_less): Handle unsigned int comparisons.
4671 Add FIXME about pointer compares, which assume host and target
4672 pointers are the same.
4674 * command.c (do_nothing_command): lint
4675 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4676 fix comments on debug symbol format for visibility. Actually set
4677 visibility of symbols.
4678 main.c (echo_command): lint; use <readline/history.h>.
4679 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4680 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4681 pointing past end of allocated memory; saber complains.
4682 obstack.h: Declare the external functions that we use.
4683 valarith.h: use <string.h>
4684 solib.c (solib_add): lint.
4686 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4688 * main.c (initialize_main): Default info_verbose to off, now that
4689 symbol reading is fast.
4690 (quit_command): Avoid clobbering exec_bfd while quitting.
4692 * Initial BFD (binary file diddling library) merger:
4693 coffread.c: Change AOUTHDR to struct exe_hdr.
4695 core.c: initialize initialized data at compile time.
4696 (core_file_command): Move from coredep.c, convert to bfd.
4697 (xfer_core_file): Convert to bfd.
4698 exec.c (exec_file_command): use bfd routines.
4700 mips-tdep.c: Remove exec_file_command and friends.
4703 * coredep.c: (fetch_core_registers) Convert core_file_command to
4704 fetch_core_registers.
4705 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4707 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4708 (my_bfd_read): More bogosity, which I don't think we call.
4709 (program_name): Remove this atrocity asap!
4711 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4714 values.c: allocate_repeat_value was not clearing the
4715 optimized_out field.
4716 (value_static_field): minor stylistic fix (wrong macro was used).
4717 valops.c (value_struct_elt_for_address): didn't work for C++
4720 * signame.c (_initialize_signame): Initialize signal names once.
4722 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4723 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4724 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4726 * remote-eb.c: Support user-settable baud rates on the serial port.
4728 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4730 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4732 * tconfig/sun3os4: Remove warning about native assembler,
4733 since it also occurs in the xconfig file.
4735 * findvar.c (registers): Allocate some slop after `registers'
4736 to prevent stray accesses from trashing the next variable.
4738 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4739 on the sun-3, by changing the #ifdef from `sun3' (which is not
4740 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4741 vars, which happened to follow `registers' in the executable.
4743 * readline/history.c (history_search): Heed gcc-2's advice
4744 and parenthesize && inside ||).
4746 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4747 tm-29k.c: Insert FSF copyright headers.
4749 * remote-eb.c: Better comments.
4751 * Makefile.dist: Update to 3.91.6.
4752 * TODO: note PREPARE_TO_STORE problem.
4754 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4756 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4758 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4760 * infrun.c (wait_for_inferior, at end): Don't set up
4761 prev_* if the inferior no longer exists.
4763 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4764 CANNOT_EXECUTE_STACK.
4765 valops.c (call_function): Use it.
4767 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4769 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4770 infrun.c (wait_for_inferior, 2 places): Use it.
4772 * values.c (value_being_returned): Only use
4773 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4775 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4776 right thing for remote-eb.c.
4778 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4779 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4781 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4782 (FRAME_FIND_SAVED_REGS).
4784 * findvar.c ({fetch,store}_registers): Check for
4785 REMOTE_{FETCH_STORE}_REGISTER macro.
4787 * findvar.c (get_saved_register): Add argument lval and
4788 change meaning of argument addr.
4789 findvar.c: Change calls to get_saved_register to reflect
4790 new calling convention.
4791 valops.c (value_assign): Use get_saved_register instead of
4792 find_saved_register.
4794 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4796 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4797 an (uninitialized) pointer to one. Use "&" when passing it
4800 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4802 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4805 * coffread.c (symbol_file_command): Put semicolon after
4807 Put safe_to_init_tdesc_context in #if defined (TDESC).
4808 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4809 coffread.c: #include <sys/stat.h>.
4810 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4811 Add missing ')' in check for "lc%" and friends. Remove
4813 Declare read_one_sym() at top of file.
4814 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4815 MC68WRMAGIC can have the same value without causing a duplicate
4818 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4820 * Allow a Makefile to be built without building the
4821 tm and xm file links that screw up builds in subdirectories.
4822 This is done with `config.gdb none', then you can do things
4823 like `make gdb.tar.Z'.
4824 * tconfig/none: Config file for no target system
4825 * xconfig/none: Config file for no host system
4826 * config.gdb: If no TM or XM files are called out by the
4827 host or target file, don't make links for them.
4829 * cplus-dem.c: Add documentation.
4831 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4832 simple error, so the user's gdb doesn't crash due to some object
4833 file problem (e.g. somebody is rebuilding the file out from under
4836 * printcmd.c (print_address_symbolic): demangle the symbol.
4838 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4839 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4840 (alldeps.mak): sort and uniq all results from this; duplicates
4841 hose gdb.tar.Z link building. Remove RCS files from
4842 tconfig and xconfig. Add config files for sun386. Add
4843 a few odd files to OTHERS and HFILES.
4845 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4847 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4848 Roll version number to 3.91.5. Make lint work in bindir.
4850 * README: Document cross-debugging and new file structure.
4852 * blockframe.c: Lint. Include "value.h" to declare read_register.
4853 (find_pc_partial_function): remove duplicate line.
4855 * command.h: Lint. Declare error_no_arg and dont_repeat.
4857 * tm-news.h: Remove inadvertently duplicated stuff.
4859 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4860 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4862 * config.gdb: Allow `config.gdb host target' form. Clean
4863 up previous change that printed bogus messages when you just said
4866 * core.c: #include "command.h" for lint.
4869 * main.c: Remove some casts of enums. Lint.
4876 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4878 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4879 read it from memory. This will allow us to save ptrace calls
4880 eventually. Changed caller single_step too.
4882 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4883 that we aren't going to use, saving many ptrace calls, especially
4884 when watchpointing or single stepping. Use some #define's for
4886 (store_inferior_registers): Ditto.
4887 (core_file_command): Use some #define's for constants.
4889 * tm-sparc.h: Add #define's for some register numbers, so we
4890 can eliminate the use of random constants in sparc-xdep.c.
4892 * stack.c (frame_command, print_frame_info, up_command,
4893 down_command) Remove frame_changed, since it
4894 causes a bug and doesn't seem to do anything useful. In some
4895 places it was used as a flag, in others as a stack level (?).
4897 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4898 default is to use the portable (vprintf) version rather than the
4900 * xm-news.h (MISSING_VPRINTF): Add.
4902 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4904 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4906 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4907 about linking debugged programs -Bstatic in the sun?os4 config
4908 files in tconfig and xconfig subdirectories.
4910 * main.c (main): Remove unreached exit(0) now that we exit
4913 * Create TODO file for online bug list. There are too many
4914 "little" bugs to keep track of on paper.
4916 * Change Projects file to refer to bug-gdb@cygnus.com
4917 rather than kingdon@ai.
4919 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4921 * Makefile.dist (VERSION): 3.91.4 now.
4923 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4924 (condense_misc_bunches): Add sanity check that misc_count is
4925 the same as the number of symbols in the bunch.
4927 * coffread.c: rename init_misc_bunches. Pass an argument
4928 to condense_misc_bunches (a zero).
4930 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4931 every time we are called; don't rely on our caller to do it.
4932 (add_file): Remove call to init_misc_bunches.
4934 * mipsread.c: Only warn, don't error, if unknown symbol types.
4935 This keeps an old gdb from falling on its face if it sees newly
4936 extended symbol info. Rename init_misc_bunches.
4938 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4940 * Merge in changes from Per Bothner for DECstations and other
4941 MIPS stuff. The rest is Bothner speaking:
4943 The next message is a merger of Alessando Forin's mips port with
4944 mine. I've tried to use my good if biased judgment to get
4945 the best of both. It *does* need testing.
4947 Some of the changes are general, *not* mips-specific.
4950 Didn't believe in little-endian bit order.
4951 There are still inconsistencies about whether flags
4952 like BITS_BIG_ENDIAN are integer (#if ...) or
4953 boolean (#ifdef ...). I tried to paper over them.
4955 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4956 Moved some misc_function code that was common to
4957 {dbx,coff,mips}read.c to symtab.c.
4958 In the process, I think I cleaned things up a bit.
4959 At the same time, moved obsavestring and obconcat to symtab.c.
4962 Removed obsolete condense_addl_misc_bunches (use
4963 condense_misc_bunches(1) instead).
4966 Needed to include <sys/dir>, at least on DECstations.
4968 valops.c, mips-tdep.c, tm-mips.h:
4969 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4970 conventions (when STACK_ALIGN is insufficient).
4971 Needed on mips, where doubles need 8-byte alignment,
4972 but ints only need 4.
4975 Removed cruft that was not being used.
4976 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4979 Print $ before register-names (I think that makes things a little
4981 Never print two instructions, even if one delays.
4982 Removed hex-disassemble set_cmd. (This is not mips-specific,
4983 so I think the argument is whether it is generally worthwhile or not.
4984 I'm inclined to think not, given how easy it is to
4985 convert between radixes in gdb.)
4988 This is basically Alessando's code.
4989 It doesn't use obstacks; I changed it to use obstacks
4990 in a few minor places where using malloc causes a
4991 memory leak. (Probably, more places could/should be changed.)
4992 I added record_misc_function where it was missing.
4993 In symbol_file_command and add_file_command, I tried
4994 to make the code consistent with more recent versions.
4995 Minor sylistic changes in parse_procedure.
4996 Make a .gdbinfo. psuedo-symbol point back to the real
4997 procedure symbol (using the isym field).
5000 This is basically from my port, but with a lot of details
5001 and a number of routines merged in from Alessando's version.
5002 I basically used my code "raw" backtrace (use heuristics
5003 from the actual code, rather than symbol table info) - though
5004 the idea is Alessandro's. I feel my code is a little cleaner
5005 here, particularly in being a little more flexible, such as being
5006 able to handle gcc-produced code (which it now can).
5007 It also doesn't do frame caching (which is not useful
5008 more recent gdb versions).
5009 I also used my code for push_/pop_dummy, more or less.
5010 I tried to incorporate AF's code for testing sigtramp
5011 while backtracing; I probably got it wrong.
5012 Added mips_print_register, which tries to scrunch as much
5013 information as possible on a screen...
5014 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5015 under mips-pinsn.c), I don't see anything mips-specific here,
5016 and I don't see it being all that useful anyway.
5019 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5020 Use more register names (rather than hard-cases numbers).
5022 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5024 * Hack up 3.90.11 changes:
5026 * Makefile.dist (depend): parameterize $(GCC).
5027 Add solib.c and solib.o.
5028 (readline): Fix vpath for both absolute or relative SRCDIR.
5030 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5031 Also, let the part I didn't understand at least compile so
5032 I can test the rest. FIXME.
5034 * dbxread.c: Fix thinko using strcmp.
5035 (init_psymbol_list): declare static.
5036 (partial_symbol_file_open): Comment cleanups better, avoid
5037 cleaning up the string table since the caller will do that.
5038 Move the stat for mod time into symbol_file_command, temporarily.
5039 (There should be a mod time for each symbol file, eventually,
5040 to control its rereading. FIXME.)
5042 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5043 SunOS, which gives error for shared libs otherwise. (From
5044 Schaefer, probably FIXME needs work for portability.)
5046 * solib.c: Move #include "param.h" to work.
5047 Lowercase all the Uppercase Letters In the Messages.
5048 (find_solib): Clean up inferior_so_name for debug printouts.
5049 Allow no argument, to mean all shared libraries.
5051 * symmisc.c: include param.h to get CLEAR_SOLIB.
5053 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5055 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5056 to 3.90.11. ChangeLog entries below are from this.
5058 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5062 * Makefile.dist (HFILES): Add tm-sunos.h.
5064 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5068 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5070 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5072 * sparc-opcode.h Added single-operand version of rett.
5074 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5076 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5077 Put parens around gcc_p in expansion.
5079 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5081 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5083 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5085 * Changes for Sun shared libraries:
5086 blockframe.c (find_pc_partial_function): If a non-text symbol
5087 is found, set *address = pc - FUNCTION_START_OFFSET.
5088 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5089 Disable breakpoints instead of giving an error.
5090 source.c (select_source_symtab): Initialize cs_pst.
5091 symmisc.c: Call CLEAR_SOLIB if defined.
5092 symtab.h: Make text{low,high} CORE_ADDR not int.
5093 (psymtab): New field addr.
5095 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5096 (record_misc_function): Give correct type for N_DATA symbols.
5097 (condense_misc_bunches): do "misc_function_count = j" regardless
5099 Take code which is shared between symbol_file_command and
5100 add_file_command and put it into partial_symbol_file_{open,read}.
5101 Split add_file_command into add_file_command and add_file.
5102 Make psymtab_to_symtab read in the string table if the file
5104 Two new parameters to read_dbx_symtab and start_psymtab.
5105 tm-sunos.h: New file.
5107 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5109 * infcmd.c: Change cont_command to continue_command and "cont"
5112 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5114 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5116 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5118 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5119 size 1,2,4,8 rather than size < 8.
5121 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5122 as necessary, not just once.
5124 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5126 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5128 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5130 * tm-news.h: Add CALL_DUMMY_*.
5132 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5134 * config.gdb: In list_host, list_target, use ${i}, not $i.
5136 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5138 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5140 * sparc-opcode.h: Change all store floating-point state register
5141 instructions to have the right match & lose fields.
5143 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5145 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5147 config.gdb: If srcdir != ., create readline directory and
5148 copy a makefile into it.
5150 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5151 consistency with POSIX.
5153 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5154 when we exit its exp_valid_block.
5156 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5158 * Makefile.dist: Bump version to 3.91.3.
5160 * Clean up handling of breakpoint commands (somewhat).
5161 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5163 inferior.h: Add breakpoint_proceeded to inferior status struct
5164 and globals; save it and restore it.
5165 (clear_breakpoint_commands): Cleanup, remove old #define.
5167 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5168 (save_inferior_status, restore_inferior_status): handle it also.
5169 (proceed): Remove earlier code that set breakpoint_proceeded.
5170 It is now set only in clear_proceed_status.
5171 (clear_proceed_status): Cleanup, use bpstat_clear rather
5172 than clear_breakpoint_commands. No callers need the stop_bpstat
5173 between clear_proceed_status and proceed.
5175 infcmd.c: Add breakpoint_proceeded definition and comment.
5176 (cont_command, jump_command, signal_command): Move call to
5177 clear_proceed_status right next to call to proceed.
5179 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5180 caller's argument while running down the chain of breakpoints.
5181 Use new variable "breakpoint_proceeded" to determine when
5182 a command that it executes moves the inferior past the
5184 (bpstat_clear): Handle NULL argument.
5185 (bpstat_clear_actions): Avoid useless call to
5186 breakpoint_auto_delete.
5187 (delete_breakpoint): Clean up bpstat's that are pointing to
5188 the deleted breakpoint from the stop_bpstat chain.
5189 (breakpoint_auto_delete): Simplify.
5191 * Clean up handling of EOF, error on stdin, etc. This was
5192 prompted by a network problem that caused gdb to go into an
5193 infinite loop filling up its malloc'd memory.
5195 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5196 not clear_breakpoints_commands, which is now gone.
5197 (main): If command_loop returns (e.g. from EOF on stdin), do
5198 a quit_command (looping back to command_loop if quit_command
5199 doesn't really quit).
5200 (command_loop): check result from command_line_input and
5201 exit if it returns NULL, rather than passing the NULL to
5203 (gdb_readline): Free malloc'd result space before returning
5206 * utils.c (query): Handle C-d to mean "yes", just as if the
5207 input was not a terminal. Also avoid infinite loop if EOF
5208 occurs in mid-input-line before newline. This allows
5209 query to be used at EOF on stdin with reasonable results.
5211 * infrun.c (proceed): Set breakpoint_proceeded.
5213 * values.c (value_as_long): Avoid infinite recursion for enums.
5214 (_initialize_values): Fix typo in help msg (kingdon).
5216 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5217 RL_LIB for linking. This allows -lreadline for linking
5218 and nothing for dependencies, once readline is a real library.
5220 * config.gdb: Jim Kingdon: give useful error message if the
5221 host or target type is not recognized.
5223 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5224 it just defines it. Dumb, but deal with it.
5226 * Jim Kingdon suggests:
5227 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5229 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5231 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5233 * Clean up Bothner's changes.
5235 * blockframe.c (clear_pc_function_cache): New function.
5236 * blockframe.c: remake cache_pc_function_* static.
5237 * dbxread.c (symbol_file_command): remove references to
5238 cache_pc_function_* variables.
5239 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5240 * printcmd.c: Avoid kludging a global variable (addressprint)
5241 to avoid printing the address of a string twice. Instead,
5242 pass the format letter 's' down low enough that it can be seen
5243 to avoid this problem.
5244 (print_formatted): Pass format arg to value_print.
5245 (restore_addressprint): Remove function.
5246 (do_examine): Avoid hacking addressprint, cleanups and such.
5247 (print_frame_args): Add a comment to a Bothner change.
5248 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5249 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5250 to wipe out the values cached in blockframe.c.
5251 * symtab.c (find_method): Add comment saying how big you must
5252 allocate to be "big enough". Per being terse again.
5253 * valprint.c (val_print): Handle format letter "s" to print
5254 strings without addresses. Add comment to vtbl printing code
5255 which casts with wild abandon. Rearrange reference-printing
5257 @0xaddr: value (print w/addressprint)
5258 value (print w/~addressprint)
5259 @0xaddr (parameter lists w/addressprint)
5260 or nothing (parameter lists w/o addressprint)
5262 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5264 * Merge more changes from Per Bothner:
5266 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5267 annoying) that I tried to improve it. Here are my suggestions.
5269 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5272 Do automatic de-reference when taking the address of a reference.
5274 Don't deref_ref when printing parameter lists.
5276 More attempts at treating refernences properly.
5278 In val_print, if deref_ref==0, don't print dangling " = ".
5280 Add COERCE_REF macro, which de-references an REF.
5282 * Merge changes from Per Bothner:
5284 * Fixed (Sony news)-specific configuration problems.
5285 * Fixed other problems with using vanilla pcc and libc (enum problems;
5286 assumption that vsprintf exists).
5287 * Some major speed-ups (finc_pc_partial_function now caches a match;
5288 parsing avoids duplicate symbol_lookup calls).
5289 * Changed handling of baseclasses (no longer use baseclasses field
5290 of struct type, use the first n_baseclasses fields instead).
5291 * Various minor changes/fixes, most C++-related.
5294 Cache the most previous match from find_pc_partial_function.
5295 (Save both low and high ends of matching function's pc range.)
5296 This speeds up the loop of infrun.c:wait_for_inferior quite
5297 a bit, and makes step/next commands much zippier.
5299 Added an enum->int cast (otherwise, some compilers barf).
5301 No longer set baseclass offset to 0, since multiple
5302 inheritance now mostly works.
5303 Added a number of casts, to shut up compiler warnings
5304 (after stabs where made enums, not ints).
5305 When discarding a symbol table (in symbol_file_command),
5306 must clear the cache introduced in blockframe.c.
5307 Don't convert $vtbl_ptr_type to vtbl any more.
5308 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5309 Mask off sign bit emitted by g++ for virtual table offset.
5310 Set voffset to -1 (not 1) for static member functions.
5312 Changed parsing/lexing of names to avoid doing symbol lookup twice
5313 (once when lexing to determine symbol class, once for real).
5314 Now only call symbol_lookup once. Fields of 'this' win especially big.
5316 Subpress printing addr twice in the case of 'x/s addr'.
5318 lookup_basetype_type is no longer used.
5319 Add find_methods as recursive helper function to decode_line_1.
5320 This allows multiple inheritance to work.
5321 Also, once one or more matches has been found, do not look in
5322 base-classes. (Baseclass methods would be overridden, anyway.)
5324 Removed baseclasses array in struct type.
5325 Instead of using baseclasses[i], use fields[i-1].
5326 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5327 Changed sign convention of voffset (previous was inconsistent).
5329 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5331 Used to assume existence of vsprintf. Re-written to not need it
5332 if HAVE_VPRINTF is undefined.
5334 typecmp was too pessimistic. Made it less so.
5336 Don't print space after address.
5337 If vtable points to a misc symbol (with 0 offset), print it,
5338 since that indicates the actual class of the object.
5339 Changed ype_print_derivation_info to use new inheritance
5340 scheme (without baseclasses vector).
5342 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5343 Also, changes needed because TYPE_BASECLASSES were removed.
5345 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5347 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5350 If there is no path set, and the symbols don't indicate what directory
5351 a file was compiled in, look in the current directory. But either
5352 a path or a known compilation directory will prevent this.
5355 Three independent bug fixes:
5356 * Remove the #if 0 block that breaks some stuff.
5357 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5358 adapt gdb to either SunOS 4.0.* or 4.1.
5359 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5362 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5365 (type_print) Demangle the name being printed.
5366 (type_print_base) Handle botched demangling without coredump (tiemann).
5369 (check_stub_method): Document routine.
5370 (tiemann) fix bug for no-arg functions
5371 Avoid clobbering beyond end of malloc'd storage.
5372 Terminate the argument list properly.
5374 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5376 * Changes merged by John Gilmore:
5379 In breakpoint_1, use new print_address_symbolic instead
5380 of find_pc_partial_function. (This forces use of assembler-level
5381 addresses, and avoids misleading non-mangled source-level names.)
5383 Generalize ansi argument such that -1 means skip arglist totally.
5384 Removed global variable print_ansi_qualifiers (which made
5385 code non-reentrant), in favor of extra explicit arguments
5386 to internal routines.
5388 Add new helper function print_address_symbolic.
5389 Use find_pc_misc_function instead of find_pc_partial_function
5390 (since we want assembler-level symbols here).
5392 Print unknown function as just "f (...)", not "f (...) (...)".
5393 Use new fputs_demangled explicitly.
5395 Fixed a typing violation (problem: value.h cannot be imported
5396 without renaming many variable in this file).
5397 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5398 decode_line_1: Moved forward some never-reached code.
5399 Made decode_line_2 skip function prologues correctly.
5401 fputs_filtered should not demangle by default.
5402 Add new fputs_demangled to demangle on demand..
5404 Change value_struct_elt to use value_primitive_field (using recursive
5405 utility function search_struct_field). This allows foo.bar to work
5406 for multiple inheritance (so far only for data fields).
5407 Change check_field in the same way (recursive helper function
5408 to support multiple inheritance).
5409 (Note: there are more of these problems that I haven't fixed.
5410 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5411 value_of_this: 'this' symbol name is now just "this", note "$this".
5413 Don't print static members.
5414 Avoid printing "members of <type>" if there are none.
5415 Simplified type_print_derivation_info by merging duplicate code.
5416 Remove useless blank lines in type_print_base (ptype command).
5418 Added declaration of new routine value_primitive_field.
5420 Added value_primitive_field which is generalized version of
5421 value_field that can handle multiple inheritance (non-zero offsets etc).
5422 Re-implemented value_field to call value_primitive_field.
5424 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5426 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5427 delete the whole environment. Karl Berry reported the bug.
5428 * source.c - fix openp to avoid //'s in filenames, which
5429 trigger an Emacs bug causing it to not be able to find files
5430 when running gdb in a window.
5431 * dbxread.c - zap the #if 0 that botches the add-file code.
5432 It seems to work a lot better without all the code commented out.
5434 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5436 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5439 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5441 * Makefile - added a ${CFLAGS} to a couple of entries,
5442 added remote-sa.sparc.c
5443 * added remote.sa-sparc.c, a modification of remote.c
5444 which conducts a dialog directly with the SparcStation prom.
5445 * breakpoint.c, infrun.c, sparcdep.c added
5446 remote_insert_breakpoint(), and remote_remove_breakpoint()
5447 to breakpoint.c instead of directly writing breakpoint instructions.
5448 * sparcdep.c on remote_debugging,there is no need
5449 to remove signle step breakpoint instructions.
5450 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5452 * printcmd.c - epoch interface sends lisp expressions to open up
5453 epoch windows on inspection.
5454 * valprint.c - added arrayprint, and addressprint and made adding
5455 format controls easier
5456 * wait.h added a couple of undef's because we were getting
5457 complaints about WSTOPSIG and WTERMSIG begin redefined.
5460 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5462 * symtab.c (decode_line_1): Add support for handling method stubs
5463 in the type information.
5465 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5467 * values.c (baseclass_addr): Run loop from INDEX+1 to
5468 N_BASECLASSES; otherwise, we can still get into a loop.
