1 Thu Oct 3 09:33:26 1991 John Gilmore (gnu at cygnus.com)
3 * dbxread.c (read_type): Handle error case slightly better.
4 Make complaint message not C++-specific.
6 Wed Oct 2 17:21:07 1991 Stu Grossman (grossman at cygnus.com)
8 * infrun.c (wait_for_inferior): Fix step/next so that you only
9 stop at the beginning of a new line. This fixes various problems
10 with for loops, nested if-else's and switch statements.
12 Tue Oct 1 06:33:55 1991 John Gilmore (gnu at cygnus.com)
14 * symtab.c (lookup_symtab_1, lookup_symbol): "fatal" errors
15 between symtabs and psymtabs become ordinary error()s.
17 * dbxread.c (read_dbx_symtab): Relocate end_of_text_addr
18 properly, making "end pc" correct in shared lib psymtabs.
19 (From Guy Harris <guy@auspex.com>.)
21 Mon Sep 30 13:15:31 1991 John Gilmore (gnu at cygnus.com)
23 * dbxread.c: Enable, but soften, const_vol_complaint.
24 (read_dbx_symtab): N_STSYM and N_LCSYM define static vars.
25 Ditto Gould N_NBSTS and N_NBLCS. Also, all types in the psymtab
26 should be file-scope, not global.
27 (read_struct_type): Remove ancient multiple-inheritance warning.
28 (read_range_type): Check base type, complain & patch if undefined.
29 * stack.c (frame_info): Demangle the function name in `info stack'.
32 Sat Sep 28 10:02:33 1991 John Gilmore (gnu at cygnus.com)
34 * eval.c (evaluate_subexp_for_address): Don't use
35 TYPE_POINTER_TYPE directly (it might be zero if this type has
36 never had a pointer created before); use lookup_pointer_type.
37 * symtab.c (lookup_method_type): Arguments were swapped in all
38 callers, so fix it here. I'm amazed this worked at all!
40 Fri Sep 27 18:09:31 1991 John Gilmore (gnu at cygnus.com)
42 * c-exp.y, m2-exp.y: Define more yysymbols that happen to be
43 "bss" rather than "data" symbols, but which still conflict.
46 * coffread.c (coff_symfile_read): Use xmalloc, not malloc.
47 * core.c (core_files_info): Shorten output.
48 * exec.c (exec_files_info): Ditto.
49 (build_section_table): Ignore zero-length sections.
50 * language.c, printcmd.c: Lint.
51 * language.h (get_frame_language): Declare.
52 * saber.suppress: update.
53 * stack.c (find_relative_frame): Remove complex code that was
54 #if 0'd, stick with simple code. Lint.
55 * saber.suppress: Update a bit.
56 * symfile.c (add_symbol_file_command): Add "?" to question.
57 * utils.c (parse_escape): Avoid \a due to bdead compilers.
58 * value.h: Declare typedef_print.
60 * valprint.c (val_print, type_print_base): TYPE_CODE_RANGE less
63 * nindy-tdep.c (nindy_frame_chain_valid): Use lookup_misc_func.
64 (Reported by Mark Peek <mark@imagen.com>.)
66 * solib.c (solib_map_sections): Relocate all sections, even
67 though only the text section's size is tracked. Mark ld_text
68 for eventual elimination as we generalize to N sections.
70 * infrun.c (wait_for_inferior): Don't check if the PC is in a
71 call_dummy if we were stopped by a random signal that is being
72 passed to the program. This produced wierd results when calling
73 functions in the inferior and signals (e.g. SIGALRM) were in use.
75 Tue Sep 24 18:05:30 1991 John Gilmore (gnu at cygnus.com)
77 * infrun.c (IN_SIGTRAMP): Not parenthesized properly.
78 Bugfix from Paul Eggert <eggert@twinsun.com>.
79 * tm-ultra3.h (IN_SIGTRAMP): Ditto.
80 * valprint.c (print_floating): Print 9 digits for IEEE floats.

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

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

296 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
298 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
299 entries are enclosed herein. Not all of these changes
300 have been merged into the master GDB sources -- check the
301 ChangeLog above here for the merge log.
303 Mon Jun 3 17:05:45 EDT 1991
305 m2-exp.y Created. Tested outside of GDB for a few days. Proper
306 operators were added, C specific operators and tokens
307 removed. yylex() revamped to some extent. Still things
308 missing from the grammar, such as sets.
309 Tested for two weeks in GDB v3.5.
311 Tue Jun 11 17:23:48 EDT 1991
313 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
314 so they are built-in. Sort of a hack.
316 Fri Jun 14 12:53:51 EDT 1991
318 m2-exp.y Added range checking for numeric constants. Any numeric
319 constant is assumed to be of builtin type INTEGER unless:
320 (1) it is octal or hexadecimal, in which case it is a
321 CARDINAL; (2) it is too big to fit into an INTEGER, in
322 which case it is a CARDINAL.
323 eval.c Added simple range checking for +, -, and * on integers.
324 Doesn't work very well for *, since 6 * 1,000,000,000 =
325 1,705,032,704, which fails the simple test of result >=
326 first_operand, no matter in what order the operands are.
328 Tue Jun 18 14:11:30 EDT 1991
330 Broke the parser into parts, one containing the C grammar and the other
331 containing code to be shared by all of the grammars.
333 The following files no longer exist:
338 The following files were added:
340 c-exp.y (The C grammar)
341 m2-exp.y (The Modula-2 grammar)
342 parser-code.c (Code that is shared by the above grammar)
346 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
347 now necessary to use the Bison compiler compiler, since it
348 will generate function/variable prefixes other than yy.
350 Tue Jun 18 16:47:49 EDT 1991
352 symtab.[ch] Added the external variable working_lang, than holds the
353 value of the current working language.
354 Added the ennumerated type language_mode, with the values
355 language_auto and language_manual, the former meaning that
356 GDB sets working_lang as needed, and the latter meaning
357 that the value of working_lang is totally under user
359 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
360 REAL, BOOLEAN and CHAR. Also added the type codes
361 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
362 utils.c Added set_language_command and show_language_command to
363 implement the GDB support commands "set language" and
365 expression.h A number of identifiers were added to the type exp_opcode
366 to facilitate Modula-2 builtin functions, integer
367 division, and array indexing.
369 Wed Jun 19 13:25:58 EDT 1991
371 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
372 if the language specified by working_lang requires the use
373 of strict typing of expressions. Eventually, even this
374 will be able to be changed by the user.
375 Added the macro RANGE_CHECK, which evaluates to non-zero
376 if the language specified by working_lang requires the
377 checking of a value against the domain of its type.
378 Eventually, even this will be able to be changed by the
380 language.[ch] Predicates involving types (simple_type, ordered_type,
381 same_type, integral_type, numeric_type, character_type,
382 boolean_type, float_type) are added. These predicates are
383 based on the current value of working_lang, and are handy
386 Wed Jun 19 15:39:34 EDT 1991
388 eval.c Added the function type_array_rank which computes the rank
390 valarith.c Added the funtion value_bool, which when given a integer
391 value.h value (ie. struct value *) as an argument, it returns a
392 boolean value (ie. struct value *) true if that integer
393 is non-zero, and a boolean value false otherwise.
394 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
395 will print out properly.
397 Wed Jun 19 16:36:34 EDT 1991
399 valops.c Added the function value_capitalize, which returns it
400 value.h argument capitalized if its argument is a lowercase
401 letter, or the argument unchanged if its argument is not a
403 valarith.c Added the function range_check_p, which returns non-zero
404 value.h if its value argument is between the integral bounds upper
406 Added the function range_check_enum_p, which makes sure
407 that its value argument is a valid member of the domain of
409 Added the function range_check_range_p, which makes sure
410 its value argument lies between the upper and lower bounds
411 of its type argument, which must be a ranged type.
412 Added the function check_array_index, which range and type
413 checks an index of an array.
414 Added the function value_multi_subscript, which computes
415 array[idx1,idx2...idxN], given a value array and an array
416 of values representing indicies.
417 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
418 unpack_long to work with TYPE_CODE_BOOL and
421 Wed Jun 19 18:04:08 EDT 1991
423 symtab.c Stored pervasive types in a structure and make
424 lookup_pervasive_type() a lookup function that was based
425 on working_lang. If lookup_pervasive_type() returned
426 non-zero, then that value was returned (a fix, since
427 before it simply wouldn't return the pervasive type.)
428 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
429 non-zero if the language specified by working_lang means
430 "conversion" when it says "cast".
431 valops.c Added the function value_real_cast(), which performs a
432 value.h *cast*, not a *conversion*, which is what value_cast()
433 does when it can. In particular,
434 value_cast(<float_type>,4) = 4.0, while
435 value_real_cast(<float_type>,4) = some mess.
436 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
437 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
438 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
439 and MIN on integral types. *NOTE*: These are currently
440 hardcoded to work only if there are 8 bits per storage
442 eval.c Made logical functions call value_bool to return a
443 properly typed boolean value, based on working_lang.
445 Thu Jun 20 11:55:27 EDT 1991
447 valprint.c Types now print out in a Modula-2 fashion. This works for
448 the cases when the type is printed out step-by-step, that
449 is, it doesn't work when the name of a structured type
450 (which includes the keyword "struct", etc.) is simply
452 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
453 since type specifications in C and Modula-2 are very
454 different. The C printing of a type is very recursive,
455 whereas in Modula-2 it is generally very simple. C has
456 type prefixes and suffixes, which have no real analogue in
457 Modula-2. Maybe type_print() should call a language
458 specific type printer. This is also advantageous if we
459 compile GDB to exclude some of the languages. We'll just
460 leave those functions out.
462 Thu Jun 20 16:57:10 EDT 1991
464 dbxread.c When reading the complete symbol table in (via
465 psymtab_to_symtab()), the number and types of function
466 arguments are added to a function type. define_symbol()
467 calls add_param_to_type() to accomplish this.
468 Assumption: when we come across a function definition
469 (N_FUN symbol with an 'f' or 'F' in the name), its
470 arguments will appear before another function definition.
471 When a function is found, a pointer to its type is placed
472 in the global in_function_type. Changes that
473 add_param_to_type() makes are to this global.
474 valprint.c The type of a function now includes (for Modula-2) the
475 types of its parameters.
476 eval.c Type checking and a check for the proper number of
477 arguments is now done for function calls. Not sure of the
478 impact this has on C++ member function yet.
480 Thu Jun 20 19:58:48 EDT 1991
482 valprint.c Rewrote the type printer. Broke it into two language
483 specific parts, adding the functions type_print_m2() and
485 An unfortunate consequence is this: if you debugging a C
486 program in Modula-2 mode (why?), info types does not work
487 well with regular expressions, since the types are printed
488 out in Modula-2 terminology, but stored in C terminology.
489 language.[ch] Added the functions new_type_last(), type_keyword(), and
490 type_sep() to aid in the printing of typedefs.
491 symtab.c Made the printing of typedefs as language independent as
492 possible through calls to new_type_last(), type_keyword(),
495 Fri Jun 21 11:50:26 EDT 1991
497 dbxread.c Check all incoming ennumerated types. If it looks like
498 Modula-2's BOOLEAN type, then change the type_code of the
499 type to TYPE_CODE_BOOL so we can process it as a boolean
501 valprint.c Replaced some of the 0x%x with calls to sprintf and
502 hexformat() in val_print().
503 language.[ch] Added the function hex_to_string(), which converts its
504 integral argument to a hexadecimal number (format is
505 language based) and returns the result as a string.
507 Mon Jun 24 12:25:07 EDT 1991
509 valprint.c Some functions call type_print_1() directly, instead of
510 value.h using type_print(), so they can specify where (column) to
511 print things. Since type_print() takes care of language
512 dependence, that needs to be called first. Added a
513 parameter depth to type_print() (so it is now like
514 type_print_1). Changed type_print to type_print_at, and
515 made type_print a macro that passes a depth argument of
517 symmisc.c Changed all calls to type_print_1 to calls to
519 Makefile.dist Made it possible to build GDB for a specific set of
520 depend languages. Do this by passing a definition for the macro
521 LANGS to make. LANGS should be a string containing a
522 space-separated list of language names (ie. LANGS="c m2").
523 The default is to build all languages. Note that grammar
524 files must follow the naming convention of <lang>-exp.y.
525 gdb.lang This holds the current value of the LANGS macro. It is
526 examined every time make is called, and is updated if
528 eval.c Added #ifdef _LANG_<lang> to these files.
529 expread.c Still need to add them to dbxread.c and coffread.c.
537 Mon Jun 24 16:33:11 EDT 1991
539 language.[ch] Added the functions hexformat_pre() and
540 hex_to_string_pre(), which take a prefix argument to
541 include in the format string. Thus, hexformat_pre("08") will
542 return "0x08x" (if the working language is language_c).
543 Made hexformat() and hex_to_string() calls to the above
544 with "" as the prefix argument.
546 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
547 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
548 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
549 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
550 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
551 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
552 valprint.c, vax-pinsn.c
554 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
555 calls to hexformat() and hex_to_string(). Format strings without
556 the leading "0x" were ignored.
558 depend Updated to take the above into account.
561 Tue Jun 25 15:27:18 EDT 1991
563 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
564 and type_check_t to keep track of the current state of
565 range and type checking.
566 main.c Added the variables range_mode, range_check, type_mode,
567 and type_check to record the current state of range and
568 type checking. Added initialization code to main().
569 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
573 Tue Jun 25 17:57:08 EDT 1991
575 dbxread.c process_one_symbol() updates the variable (enum language)
576 source_lang based on the extension of the filename
577 contained in the N_SO sybmol that started this symtab.
578 When end_symtab() is called, the value of source_lang is
579 put into the language field.
580 stack.c select_frame() sets working_lang (and possibly type_check
581 and range_check) to the language field of the symtab
582 associated with the frame that is selected if working_mode
583 is language_auto. If working_mode is language_manual, a
584 warning is printed and working_lang is not set.
585 language.c Added the function set_type_range(), which sets the value of
586 type_check and range_check (if their modes call for
587 automatic setting) based on the current value of
588 working_lang. A non-zero argument will cause the current
589 settings to be output.
592 Wed Jun 26 14:51:40 EDT 1991
594 eval.c Added range checks on assignment.
595 m2-exp.y Added the grammar for sets to the language. Currently,
596 these do not do anything except print an error message.
598 Wed Jun 26 17:01:04 EDT 1991
600 m2-exp.y Added the ability for parse_number() to parse negative
601 numbers. A global flag is set upon encountering a unary
602 minus. This was done to make, for example, 1 parse as a
603 CARDINAL, and not as an integer, per Wirth's examples in
604 Programming in Modula-2 ed.4.
605 valprint.c Added support for "set radix 2" by then setting
606 output_format to 't'.
607 eval.c Implemented range checking on subrange types. Added calls
608 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
609 Implemented MIN and MAX for ennumerated types. The
610 minimum value of an ennumerated type is defined by Wirth
611 as the first identifier, and the maximum as the last.
612 m2-exp.y Made octal numbers ending with "B" be characters and those
613 ending with "C" be numbers, per Wirth's book. (p. 34)
615 Thu Jun 27 14:11:52 EDT 1991
617 stack.c select_frame() now only sets working_lang, it does not
618 notify the user. If working_mode is language_manual, then
619 a warning is issued once.
620 main.c At the end of each call to execute_command(), working_lang
621 is checked against the local static (enum language)
622 current. If they differ and working_mode is
623 language_auto, the new settings of language, type and
624 range checking are printed out.
625 stack.c Modified frame_info() to include the language of the
626 current frame in the output of "info frame".
627 language.[ch] Added the function language_str() which returns the name
628 of the current language.
630 Fri Jun 28 15:33:14 EDT 1991
632 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
633 the language. INCL and DECL currently cause an error,
634 since sets are not implemented yet. INC and DEC are
635 implemented as PREINCREMENT/PREDECREMENT with one
636 argument, and as ASSIGN_MODIFY with two arguments.
637 eval.c Added type checking to the above cases.
638 value.h Added not_lval_constant to the lval_type ennumerated type.
639 not_lval_constant means that the value is a constant
640 value; that is 3 or 'a' or TRUE, not as in a constant
641 identifier. This is used to help coerce numbers such as 3
642 to either signed or unsigned numbers.
643 valops.c Added the function value_coerce_constants() which coerces
644 constant integers as following: if one is a constant and
645 the other is not, the constant's type is set to the type
646 of the other argument. If both are constants and one is
647 signed, the other is converted to a signed constant.
649 Sat Jun 29 17:26:29 EDT 1991
651 valarith.c Added a better range checker. It now checks range
652 (successfully) on integral operations [+-] (signed and
653 unsigned) for any C sized type. Still does not work well
655 int_in_size() returns an integer that is coerced to fit into
656 specified number of bytes.
658 Mon Jul 1 13:04:14 EDT 1991
660 language.[ch] Added the function binop_result_type(), which returns the
661 builtin (struct type *) type that would be the result of a
662 binop on the two values V1 and V2.
664 Wed Jul 3 19:22:53 EDT 1991
666 source.c Extended source_info() to include the source language in
667 the output from "info source".
669 Fri Jul 5 13:48:52 EDT 1991
671 utils.c Moved the support functions for the GDB set/show commands
672 dealing with language into language.c.
673 language.c Added the function language_info(), which displays info
674 about the current working language, type and range check
675 settings. Called via the GDB command "info language".
676 Added an initialization routine _initialize_language(),
677 that sets defaults for the language, type and range
678 variables and sets up the new GDB commands.
679 main.c Language setup moved to language.c.
682 Mon Jul 8 10:10:22 EDT 1991
684 valarith.c Debugged the range checker for arithmetic. Still does not
685 work for multiplication very well.
687 Mon Jul 8 12:40:37 EDT 1991
689 language.[ch] Added the function value_true() which returns non-zero if
690 its argument represents a boolean true value.
691 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
692 check the truth of an expression.
694 Thu Jul 11 12:51:34 EDT 1991
696 language.[ch] Added the predicate structured_type(), which returns
697 non-zero if the argument is a structured type.
698 Added the predicate pointer_type(), which returns non-zero
699 if the argument is a pointer type.
700 eval.c Added the ability to do addition and substraction on
701 pointers and integers. This case simply bypasses the
704 Thu Jul 11 14:41:42 EDT 1991
707 Added the symbol N_DEFD (0x4a) which is a definition
708 module dependency that is used by the GNU Modula-2
709 compiler and the linker. It is not important to GDB,
710 except that [dbx|coff|mips]read.c should ignore these
713 Fri Jul 12 16:07:00 EDT 1991
715 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
716 0 in val_print(). Also added statements to the else part
717 to coerce type (argument to val_print) to a pointer type
718 if it is an "array of unspecified length".
719 valops.c Added the function value_m2_string(), which returns a
720 (value) value which is a constant string, whose type is
721 (ARRAY [0..n] OF CHAR). The length field of the type
722 structure is set to zero, so it will be interpreted as an
723 "array of unspecified length".
724 stack.c Moved the language/frame mismatch check to
725 main.c:execute_command().
726 main.c The working language is recorded each time
727 execute_command() is executed. If working lang has
728 changed during its execution, then the new
729 language/type/range info is printed out for the user. If
730 the working language does not match the language of the
731 frame, a warning is issued.
733 Sat Jul 13 16:16:39 EDT 1991
735 eval.c Moved all the type-checking stuff for operators to
736 language.[ch] language.c. This is so we can keep language-specific
737 stuff (like for what type operators are defined) in
739 language.[ch] Added the function binop_type_check(), which checks to see
740 if its two (value) arguments are type-compatible with its
741 opcode argument. The opcode should represent an operation
742 involving an operator. Also added the macro function
743 unop_type_check, which calls binop_type_check with a
744 NULL second argument.
745 expprint.c Added Modula-2 operators to the op_print_tab, so info
746 expression.h break works correctly. Also added "op_string", which
747 returns the string corresponding to the (enum exp_opcode)
748 opcode that is its argument.
751 Sat Jul 13 18:26:18 EDT 1991
753 coffread.c Added code to record the type of function arguments with
754 each paricular function. Code is very similar to that
756 dbxread.c Moved add_param_to_type() to symtab.c
757 symtab.[ch] Added function add_param_to_type() from dbxread.c
759 *** NOTE: The above additions have not been tested.
761 Mon Jul 15 12:50:47 EDT 1991
763 langauge.[ch] Added the functions type_error and range_error, which work
764 like error() except if the type/range mode is set to
765 *_mode_warn, then they do not do a return_to_top_level(),
766 but merely print a warning.
767 Also changed [set|show]_[type|range]_command() to support
768 the new "warn" feature.
770 Thu Jul 18 17:50:54 EDT 1991
772 mipsread.c Added code to record the type of function arguments with
773 each particular function. Code is very similar to that
776 *** NOTE: The above additions have not been tested.
778 Fri Jul 19 11:19:10 EDT 1991
780 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
781 UMIN_OF_SIZE, which when given a size of a numeric type,
782 return the maximum and minimum value it can hold. UMAX...
783 and UMIN... return the result for unsigned types.
784 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
785 struct types. They call above macros.
786 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
787 avoid a name conlict with the above.
788 c-exp.y Added range checking on numeric constants in
789 parse_number() for completeness.
790 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
791 return 0 if working_lang is not language_c.
793 Thu Aug 8 14:17:22 EDT 1991
797 breakpoint.c Documentation strings of some commands changed to
798 eliminate the references to the C language where
801 Tue Aug 13 15:48:03 EDT 1991
803 m2-exp.y Added qualified identifiers to the grammar. The semantics
804 are slightly different from those of the GDB operator ::
806 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
807 type_exp, where type_exp is any valid type expression.
809 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
810 printcmd.c Modified ptype_command() so it actually parses the input
811 (necessary for type expressions with scope qualifiers).
812 Added the function ptype_eval() which expects an
813 expression composed of one OP_TYPE element.
814 *.[ch] Replaced all occurences of parse_c_expression with
816 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
818 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
820 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
822 Small fixes from Peter Schauer:
824 * infrun.c (child_attach): Lint.
825 * solib.c (find_solib): Handle shared libs version 2.
827 Small fixes from David Wood:
829 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
833 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
834 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
836 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
837 chars_per_line is at maximum (user typed `set width 0'). Fix
838 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
840 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
842 * coredep.c: include ptrace.h where necessary.
843 * mipsread.c(parse_lines): fix unsigned char problem that was
844 messing up line numbers on SGI's and possibly other MIPS based
846 * infrun.c (child_create_inferior): use better test to check
847 return val from setpgrp().
848 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
849 for sgi/irix support.
851 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
853 * mipsread.c (parse_symbol): Put non-static procedures
856 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
858 Patch together `text_start' and `text_end' for 29K port.
860 * exec.c (exec_command): If NEED_TEXT_START_END, define the
861 variables and set them based on the exec file.
862 * am29k-tdep.c: declare text_start.
863 * valops.c (call_function_by_hand): declare text_end.
865 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
866 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
867 because machines that do this will also have to know to
868 set NEED_TEXT_START_END. Besides, it was a redundant way to
870 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
871 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
874 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
876 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
878 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
879 Pass MUNCH_DEFINE to munch whenever we run it.
880 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
881 format string; use 0x%x instead.
882 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
883 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
884 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
885 * inflow.c: Handle `short' process group IDs.
886 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
887 and check for ptrace errors.
888 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
889 (coff_symfile_init): Initialize text_bfd_scnum.
890 (read_coff_symtab): Use it to find the text [and absolute?] sections.
891 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
892 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
893 Merge target arm case with other "easy" cases. Add target
894 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
895 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
897 * minimon.h, remote-adapt.c, remote-mm.c: Add.
898 * munch: Cope with RT/PC putting fns in data segment.
899 Restore ability to override `nm' by specifying MUNCH_NM.
900 * xconfig/rtbsd, xconfig/ultra3: New host systems.
901 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
902 and remote-adapt. Remove encapsulated coff #define's (the
903 support should go in BFD, and gdb shouldn't know or care).
904 * tconfig/a29k-kern: Same, but for remote kernel debugging.
905 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
906 * tm-29k.h: Update BADMAG (though it should go away).
907 Allow the register definitions to be overridden in another
908 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
909 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
910 DUMMY_SAVE_GR96, for handling kernel calling conventions
911 that use GR64+ rather than GR96+.
912 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
913 remote debugging of Ultra3 kernel. Includes tm-29k.h and
914 overrides various things.
916 * remote-mm.c (mm_attach, mm_wait): Handle attach like
917 child_attach does, making a clean stop in the newly attached
921 * coffread.c: Make coffread independent of any particular
922 variant of COFF. Avoid #include-ing any particular one except
923 internalcoff.h. BFD now passes key values for symbol reading
924 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
925 and the symbol masks and shifts); use them.
926 Remove obsolete end_of_text_addr.
928 * exec.c: Remove unused include files.
930 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
932 * Makefile.in (documentation targets): Pass $(M4).
933 Bugfix from eggert@twinsun.com (Paul Eggert).
935 * stack.c (down_silently_command): Check for stack existence.
937 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
939 * Makefile.in (VERSION): Update to 4.0.3.
941 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
943 * core.c (core_file_command): Print frame at coredump with
944 its level number, by calling print_stack_frame.
945 * frame.h: Add selected_frame_level, print_stack_frame.
946 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
947 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
948 Change print_sel_frame and print_selected_frame callers to
951 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
952 * symfile.c (free_named_symtabs): Ditto.
953 * main.c (main): wrap_here needs an arg.
954 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
955 (solib_add): Avoid noise.
956 (solib_create_inferior_hook): Lint.
957 (sharedlibrary_command): Move dont_repeat to here.
958 * utils.c (error): Call wrap_here to force buffered output.
960 Small patches from Peter Schauer:
962 * coffread.c (start_symtab): Free any existing line_vector before
964 (read_coff_symtab): Ditto for type_vector.
966 * source.c (lines_to_list): New variable, replacing function.
967 (all uses): Use as variable.
968 (_initialize_source): Add 'set listsize' and 'show listsize'.
969 * utils.c (lines_to_list): Remove function.
970 * stack.c (print_frame_info): Use as variable.
971 * defs.h (lines_to_list): Remove declaration.
973 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
975 * breakpoint.c (insert_breakpoints): Restore warning about
976 the program might be running in another process, but only for
977 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
978 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
980 * utils.c (error): if error_pre_print is set, print the string
982 * main.c (main, print_gnu_advertisement, print_gdb_version):
983 Reformat legalese so it always prints, but acts as an "I'm here"
984 message while symbols are being read. If any errors occur,
985 print a few newlines to set off the message and start it at the
986 left margin. Remove mention of "help" command, and don't yak
987 about symbol reading.
988 (catch_errors): Error string is now printed first in case of
990 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
991 suggest the "help" command.
993 * Makefile.in (VERSION): Set to 4.0.2.
995 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
997 * .gdbinit: Remove useless "rr" command. Set complaints
998 to 1 for people debugging gdb.
1000 * breakpoint.c, remote-vx.c: Reword strings printed by
1001 catch_errors callers.
1003 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
1005 * WHATS.NEW: "history write -> history save". Doc "write on/off".
1006 (Fix from kenc@viewlogic.com.)
1008 Fix some infrastructure to be able to cope with host and target
1009 machines with different sized basic types (ints, ptrs, etc).
1010 (Idea from pierre@la.tce.com (Pierre Willard).)
1012 * values.c (value_from_longest): Rename from value_from_long.
1013 Handle pointer types as well as integers, so that targets with
1014 different pointer sizes from the host can be accomodated.
1015 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
1016 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
1017 uses of value_from_long to value_from_longest.
1018 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
1019 the correct pointer type to value_from_long{est}.
1021 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
1023 * remote-vx.c: Remove obsolete code for calling functions via
1024 vxworks kludge interface (it referenced value_from_long).
1026 * valops.c (value_string): Find malloc with lookup_misc_func, not
1029 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1031 Make writing to files work properly. (Fixes to BFD are also needed.)
1033 * core.c (core_open): Open file ourselves, read or r/w, depending on
1034 write_files. Use bfd_fdopenr.
1035 * gdbcore.h (write_files): New variable.
1036 * exec.c (write_files): Define variable, add set&show for it.
1037 (exec_file_command): Use write_files to open for read or r/write.
1039 Make shared library reading happen automatically. These changes
1040 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
1042 * inferior.h (stop_soon_quietly): Add to exported variables.
1043 * infrun.c (child_create_inferior): call solib hook, if defined.
1044 (child_attach): call solib hook, if defined.
1045 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
1046 (find_solib): Use lookup_misc_func rather than hand-rolled.
1047 (symbol_add_stub): New stub for catch_errors.
1048 (solib_add): Avoid output if !from_tty. Catch errors rather
1049 than just calling symbol_file_add and bombing.
1050 (solib_create_inferior_hook): Interface with the target process
1051 to let it read and alloc shared libs, then figure out what it did.
1053 * core.c (validate_files): Fix typo, soften warning.
1054 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
1056 * utils.c (fputs_demangled): Avoid duplicate printing if
1057 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
1059 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
1060 (Fix from pierre@la.tce.com (Pierre Willard).)
1062 * main.c (catch_errors): Change argument to a char * from an int,
1063 since a char * can point to a struct full of glop, but an int
1064 is not guaranteed to be able to hold a pointer.
1065 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
1066 breakpoint_re_set_one, breakpoint_re_set): Adapt.
1067 * core.c (core_open, solib_add_stub): Adapt.
1068 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
1070 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1072 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
1073 by adding .NOEXPORT target.
1075 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
1079 * Makefile.in (VERSION): Roll to 4.0.
1080 (gdb.tar.Z): Make refcard.ps as well, for shipment.
1082 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1084 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
1087 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
1090 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
1092 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
1093 reflect above name change
1095 * WHATS.NEW: correct pointer to refcard.
1097 * doc/gdb.texinfo: update New Features, Installing
1099 * doc/gdbint.texinfo: add short description of configure +template
1101 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1103 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
1105 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
1107 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
1108 tar file, add dependencies for referenced doc files.
1110 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
1112 * coffread.c, symfile.c, stack.c: saberized.
1114 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1116 * doc/refcard.tex: permuted Essential Commands sec
1118 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1120 set/show symbol-reloading
1121 default set complaints 0
1123 RET-repeat disabled after prompted long displays
1124 processID (attach) interpretation of 2nd GDB cmdline arg
1126 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1128 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1129 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1130 breakpoint.c, main.c: lint.
1132 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1134 Install new configuration scheme for GDB and friends.
1136 * config.sub: Translate ordinary names to three-part names.
1137 * configure: Use three-part names internally.
1138 * configure.in: Translate three-part names to filenames.
1140 * README, WHATS.NEW: Update for gdb-4.0.
1141 * Makefile.in: Roll VERSION to 3.99.
1143 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1145 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1146 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1147 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1148 to single structures rather than arrays; when passing
1149 their address, use &. This avoids trouble with bdead compilers.
1150 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1151 instead. This avoids portability headaches.
1152 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1154 * source.c (open_source_file): Avoid ANSI const bdeath by
1155 skipping declaration and then casting result value.
1156 * tm-hp300bsd.h: Clarify comment.
1157 * utils.c (strstr): Result is const char *; ANSI bdeath.
1158 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1159 since system include file defines it differently from "defs.h",
1160 though the two are equivalent for our purposes.
1161 * tconfig/hp300bsd: Add m68k-tdep.o.
1163 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1165 * tconfig/sun*4: Remove warnings about system assembler.
1167 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1169 * mcheck.c: Avoid warning about undeclared abort fn.
1170 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1171 it causes recursive calls to error() when used in cleanups.
1172 To do so requires that we make it a function, so we do.
1173 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1174 * utils.c (do_cleanups): Remove the current cleanup from the
1175 chain *before* calling it, in case error() is called from it.
1176 The result won't be pretty, but won't be an infinite loop either.
1178 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1180 * dbxread.c (read_struct_type): Grok anon structs for C++.
1181 (vb_name, vptr_name): Null terminate these strings.
1183 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1185 Minor bug fixes from BSD Net2 gdb:
1187 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1188 returns 0, there is no previous frame.
1189 * breakpoint.c (commands_command): If !from_tty, don't call
1190 input_from_terminal_p().
1191 * dbxread.c (record_misc_function): Speed up slightly.
1192 (compare_psymbols): Ditto.
1193 * infcmd.c (do_registers_info): Take a second argument to
1194 determine whether to print float registers. "info registers"
1195 does not do so anymore. "info all-registers" does, now.
1196 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1198 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1199 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1203 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1204 executing_breakpoint_commands if we are interrupted by error.
1205 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1206 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1207 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1208 catch_errors() so we can setup the frame regardless of whether
1209 the shared libs work.
1210 * ieee-float.c (double_to_ieee_extended): Get exponent from
1211 right place in little-endian systems. From John Carey.
1213 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1215 * main.c: Remove unused terminating_signals and catch_termination().
1216 (long_options): Terminate with a zero element.
1217 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1218 (gdb_readline): Make call-compatible with readline.
1219 (init_signals): Improve comments re vfork vs. signal.
1221 * utils.c (prompt_for_continue): Use new gdb_readline().
1222 If we prompt for continuation, we don't let CR repeat the previous
1223 command, once we get back to a prompt. It's too easy to keep
1224 hitting CR, expecting "--more--" prompts, and have some long
1225 command start repeating on you.
1227 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1229 * blockframe.c (frameless_look_for_prologue): Speed up by
1230 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1231 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1232 Define two variants, one faster.
1233 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1234 and return zero, rather than giving an error.
1235 (setup_arbitrary_frame): Initialize the PC in the new frame.
1236 (skip_prologue): Add a second arg saying whether we're just
1237 checking for a frameless function or not.
1239 * core.c (core_open, core_close, core_xfer_memory): Move
1240 section table pointers and bfd* into the target_ops.
1241 (core_open): Allow errors in shared lib reading, etc.
1242 (core_files_info): Describe shared library sections.
1244 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1245 exec_files_info, set_section_command): Move section table
1246 pointers and bfd* into the target_ops.
1247 (add_to_section_table): Add BFD to section table.
1249 * target.c (target_xfer_memory, target_info): Pass target to
1250 xfer_memory and target_info functions.
1253 * gdbcore.h: Move struct section_table.
1254 * target.h: New home of struct section_table.
1256 * solib.c (solib_add): New argument is the target_ops whose
1257 section list is to be added to, if any. Reallocate the
1258 sections in that target to add any that come from shared libs.
1259 (throughout) so_sections renamed to sections.
1260 (solib_xfer_memory): Deleted.
1261 * tm-sunos.h (SOLIB_ADD): Add target argument.
1262 (SOLIB_XFER_MEMORY): Delete.
1264 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1265 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1266 from target_ops. It's the same on all targets. Add two section
1267 pointers to target_ops.
1269 * stack.c (find_relative_frame): Dump ancient algorithm for
1270 "down", just use handy "next" pointers.
1271 (frame_command): Don't error if there is no stack; let user
1274 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1275 modifies static state in the parent process; new_tty itself
1276 runs in the child and modifies the child's file descriptors
1277 to match the saved static state.
1278 * infrun.c (child_create_inferior): Call new_tty_prefork,
1281 * infptrace.c (child_xfer_memory): Add ignored target arg.
1282 * remote-eb.c (eb_xfer_inferior_memory): ''
1283 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1284 * remote-vx.c (vx_xfer_memory): ''
1285 * remote.c (remote_xfer_memory): ''. Rename from
1286 remote_xfer_inferior_memory.
1288 * main.c (main): Only try to attach "corefile" argument if
1289 it starts with a digit.
1291 * symfile.c (symbol_reloading): New "set/show" variable.
1292 (symbol_file_add): Shorten message about symbol reading.
1293 (add_symbol_file_command): Merge with add_syms_addr_command,
1294 since this should work on all targets now.
1295 (stop_whining): Default to zero, to shut up complaints
1296 about bad symbol tables on many systems.
1297 (free_named_symtabs): Just exit unless symbol_reloading.
1299 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1300 and add comment explaining shared library screw.
1302 * source.c: #if defined => #ifdef.
1304 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1306 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1308 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1310 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1311 (doc/Makefile knows how to make one for local config)
1313 * Makefile.in: use doc/Makefile for doc targets
1315 * doc/Makefile: GDB documentation now has its own Makefile
1316 doc/refcard.tex: renamed from "gdbrc.tex"
1317 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1318 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1321 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1323 * values.c (baseclass_addr): When reading target memory, use the
1324 length of the basetype, not the upper type. We've only malloc'd
1325 enough space for the basetype, leading to errors in free().
1327 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1328 ends up as a function specially, since we know the actual type of
1329 the pointed-to address. This (somewhat) fixes display of
1330 expressions that include misc_function_vector names. Try `cond 1
1331 !strcmp("a","b")' then `i b'.
1333 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1334 The child can be proceeded from inside wait_for_inferior in
1335 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1336 getting skipped in that case.
1338 * expprint.c (print_subexp): Use filtered output, since the
1339 subroutines we call use it, otherwise the output is horribly
1340 mangled, since output of wrappable stuff comes out late.
1342 * Makefile.in: Bump VERSION to 3.98.1
1344 * infrun.c (child_create_process): Use execlp to find the
1345 shell to exec our target program. This requires some fiddling
1346 with `environ' since there is no execlpe().
1348 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1350 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1351 Minor rearrangement of refcard permits two new make targets--
1352 gdbrc.dvi DVI output for refcard, using CM fonts
1353 gdbrc.ps PostScript refcard, using PS fonts
1355 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1359 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1360 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1362 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1364 * doc/gdb.texinfo: last changes for release.
1365 Minor typo and formatting fixes; incorporated most fixes remaining from
1366 filed mail commenting on earlier drafts.
1368 Added warnings: pipes don't work in run command;
1369 conditions are converse of assertions;
1370 step over fn without debug info goes to next fn;
1371 vars may have "wrong" values near fn entrance, exit
1373 Added example from Kingston on printing repeated nonadjacent values
1375 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1376 shell mode for signals
1378 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1379 doesn't sound so much like its parent "Stopping and Continuing"; also
1380 moved entries on continue to top of section, so they don't get lost.
1382 Improved installation directions in appendix, added manual formatting
1385 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1387 * configure.in: Remove xm.h and tm.h even if we aren't linking
1388 new ones, so "./configure sun4; ./configure none" does the right
1389 thing. Assume that alldeps.mak and depend are already built in
1390 srcdir, and avoid running "make" (particularly "make depend",
1391 which involves "gcc") from inside configure. Build Makefile
1392 directly rather than building Makefile.conf first.
1393 * configure: Regenerate with above changes.
1394 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1395 to 3.98. Revise gdb.tar.Z procedure to produce a file
1396 called gdb-$(VERSION).tar.Z but which unpacks into a
1397 directory called "gdb". Move non-source files out of
1398 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1399 (depend): Don't try to do "gcc expread.y".
1400 (expread.o): Update dependencies by hand.
1402 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1405 Fixed a variety of small typos that prevented info from formatting
1406 cleanly; altered too-long heading for GPL Appendix, as discussed
1407 w/RMS; Changed date on cover to July 91.
1409 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1412 (1) Applied some fixes due to comments from Larry Breed (easier ones
1413 through chapsec 5.2)
1414 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1415 it's broken in latest texinfo
1416 (3) Introduced *some* use of [] for optional arguments, where
1417 explanation is not simpler by listing cmd w arg and cmd w/out arg
1418 separately. Still not using @deffn.
1419 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1420 couple of headings are too long. Need patches to texinfo or revision
1423 * Partial update to README (which still needs work for this
1424 release!): (1) use of configure corrected for new script,
1425 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1427 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1429 * symtab.c (lookup_symbol): Don't complain right off about
1430 no debug symbols; use the misc function vector first.
1431 (list_symbols): Use misc function vector to find symbols
1432 that don't have debug info, and print them.
1433 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1434 PC range doesn't match symtab PC range, as it does on the
1435 MIPS because our symtab reading isn't perfect.
1437 * dbxread.c (dbx_symfile_read): Make warning about
1438 "no debug symbols" slightly nicer.
1440 * source.c (select_source_symtab): If "main" symbol exists,
1441 but decode_line_spec can't find line info, don't just return
1442 a zero; try other source symtabs or give an error.
1444 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1445 their low addresses first, then rip through fixing high addrs.
1447 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1448 <runene@ifi.uio.no>.
1449 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1451 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1453 * Minor, mostly mechanical, cleanup of doc subdir for clean
1454 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1455 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1457 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1459 Mostly MIPS and general symbol-reading fixups.
1461 * doc/gdbint.texinfo: Add documentation on symbol-reading
1464 * mipsread.c: Remove kludges around #include "ecoff.h".
1465 Remove redefinitions of a_magic, etc, no longer used.
1466 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1467 Fix global overview comments to match symfile.c protocol.
1468 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1469 (mipscoff_symfile_read): Eliminate unused code. Avoid
1470 sorting all the symtabs, when all we have read here is psymtabs.
1471 The symtabs are sorted as they are created anyway. Tell
1472 condense_misc_bunches whether we're mainline.
1473 (psymtab_to_symtab_1): Pass filename when recursing, to make
1474 stack trace more informative.
1475 (parse_partial_symbols): Assume cur_hdr as argument.
1476 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1477 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1478 the TYPE_NAME of char *, since that's done in symfile.c.
1479 (free_numargs, parse_symbol, add_symbol, add_block,
1480 shrink_linetable): Declare these fns void.
1481 (upgrade_type): Convert tree of if's to switch. Clean up
1482 bogus "off == 0" handling with a complaint. Avoid setting
1483 field bitpos and bitsize of array with lower and upper bounds.
1484 Check specified bitsize of elements against their actual type's
1485 bitsize, and complain if different. Complain about unknown
1487 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1488 (psymtab_to_symtab_1): Print names of subsidiary files that
1489 are being read in. FIXME, we read far too many files. This code
1490 is not the problem, the problem is in parse_fdr where the psymtabs
1492 (cross_ref): Result should indicate that we used one aux entry
1493 normally, or two if we encountered a "next" entry. This used
1494 to leave the caller pointing at the wrong aux entry.
1495 (add_symbol): If overflowed cur_block, reallocate it larger,
1496 chase all pointers to it, and complain(), rather than clobber memory.
1497 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1498 (new_field): Only allocate one field initially, not two.
1499 Pull ++ out of macro argument. Simplify.
1500 (_initialize_mipsread): Avoid initialization of importd
1501 global_psymbols and static_psymbols.
1503 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1504 to properly set pst->symtab; avoid searching for it.
1505 (symfile_fns): Improve comments, add a FIXME.
1506 * dbxread.c: Update comments to reflect symfile protocol.
1507 (read_ofile_symtab, end_symtab): Return the symtab.
1508 (psymtab_to_symtab_1): Set pst->symtab.
1510 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1511 whether we're mainline.
1513 * symfile.h (sym_fns): Remove unused sym_discard member.
1514 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1516 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1517 the environment variable is not.
1518 * infcmd.c (finish_command): Use filtered printfs.
1519 * cplus-dem.c: Add struct tags to a few unnamed structs.
1520 * valops.c (value_coerce_array): Improve comments.
1521 * valprint.c (type_print_varspec_suffix): Print array size only
1522 if greater than zero.
1523 * m88k-tdep.c: Shift some lines left by one space, that had
1524 apparently been trashed at some point.
1525 * TODO: More things to do, a few got done.
1527 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1529 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1530 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1532 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1533 * expread.y, findvar.c, symmisc.c: Ditto.
1534 * printcmd.c (address_info): Update printed forms of LOC_
1535 symbols. Elim LOC_EXTERNAL.
1536 (print_frame_args): Keep track of param stack offsets before
1537 re-looking up to find the local register param is kept in.
1539 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1540 Further integration of mipsread into gdb. Eliminate unused
1541 routines, duplicate declarations. Handle static symbols in
1542 psymtabs as well as external symbols. When reading symtabs,
1543 insert symbols into the correct block (global, static, or a local
1545 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1547 (mipscoff_symfile_read): Don't call select_source_symtab.
1548 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1549 rather than SYMBOL_VALUE.
1550 (parse_external): Comment clobbering of top_stack.
1551 (parse_partial_symbols): Update comments. Allocate and parse
1552 static symbols as well as external symbols. FIXME, enum values
1553 are not handled in this pass, but should be. Inline new_psymbol.
1554 Use SYMBOL_VALUE_ADDRESS.
1555 (psymtab_to_symtab_1): Read symbols into global static block
1556 by default (until enter some function's local block context).
1557 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1558 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1560 * source.c (select_source_symtab): Select a source symtab
1561 from either the symtabs or, failing that, the psymtabs.
1562 (list_command): Update error message.
1563 (forward_search_command, reverse_search_command): Use getc, not
1564 fgetc, for speed. FIXME, add comment about buffers that die if
1565 overrun by long line.
1567 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1568 by an entire word, which is not portable, if we have a 32-bit
1569 field. (Code in dbxread.c already turns such bitfields, if
1570 aligned, into ordinary ints, but fixing this will help for other
1571 symbol formats and for future changes.)
1572 * core.c (core_open): Handle ANSI const brain death.
1573 * utils.c (vprintf): Fix varargs typo.
1575 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1577 * findvar.c (find_var_value): Handle &function better.
1578 * TODO: Document work needed on &fn and &array.
1579 * printcmd.c (print_address_symbolic): New arg is the prefix
1580 to print if a name is printed.
1581 (print_address_demangle): Honor "set print address" now.
1582 Use new arg above to improve spacing of output.
1583 * valprint.c (val_print): When printing function pointers,
1584 print symbolic form too.
1585 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1587 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1589 * core.c (memory_error): Reword error msg to mislead less.
1591 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1593 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1594 parse_partial_symbols): Use newer BFD internals (external_filehdr
1595 and external_aouthdr), byte-swap the fields that we care about
1596 before using them, and make the file header data local to
1597 read_the_mips_symtab rather than global.
1599 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1601 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1602 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1604 * main.c (command_line_input): Flush stdout and stderr
1605 before every call to readline. This reportedly fixes a bug
1606 that comes up in Sys V running emacs-gdb and/or xxgdb,
1607 when stdin/out are pipes or sockets.
1609 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1611 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1612 Avoid declaring Makefile dependencies, because GNU Make stupidly
1613 tries to update it if we do.
1615 * coffread.c: Revise for minor changes to bfd internal coff
1618 * configure: If -template= is given a relative path, make it
1619 absolute before recurring in subdirectories.
1621 * configure, configure.in, Makefile.in: Install "configure" script
1622 as replacement for config.gdb.
1623 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1624 * README: Update for configure, mostly. FIXME.
1626 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1627 target config files that they are for the host. When the lines
1628 get copied into the Makefile, this makes it more obvious what's
1631 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1633 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1634 tabs, which end up in the disassembler output inadvertently.
1636 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1638 Make it compile cleanly in an ANSI GCC2 environment.
1640 * blockframe.c: <stdio.h>
1641 * cplus-dem.c: free takes a void *, ifdef __STDC__
1642 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1644 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1645 * stddef.h, stdlib.h: Remove these files.
1646 * symtab.c: Avoid declaring qsort, close.
1647 * symfile.c: Avoid declaring close.
1648 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1649 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1651 Assorted other changes.
1652 * dbxread.c: include "libaout.h", not "liba.out.h".
1653 * printcmd.c (print_frame_args): Set recurse properly for
1654 indentation of struct and array parameters.
1655 * valops.c (value_cast): Allow cast to void.
1656 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1657 single_step() in a target-independent fashion.
1658 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1659 set up to be ready to continue. This makes us target independent.
1660 * infptrace.c (child_resume): Remove call to single_step; now
1661 can single step a SPARC target of any kind.
1663 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1665 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1666 docn into separate sections---basically chapters, plus two loose
1667 pieces that can be configured to go in different places. This
1668 allows GNU m4 to preprocess the manual without coredumping.
1670 * Makefile.dist: tell TeX where to find texinfo.
1672 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1674 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1675 the new target "rdl-apps.texinfo" which captures the Makefile
1676 variable that records where to find the Readline libraries.
1678 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1680 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1681 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1682 * defs.h (const, volatile): Only define if not already defined.
1683 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1685 * README: Update for release 3.95.
1686 * config.gdb: Don't create readline dir in subdir builds.
1687 * main.c: Include with "..." form for non-system include files,
1688 so "gcc -MM" for "make depend" works.
1689 Include readline files with "...h" rather than <readline/...h>.
1690 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1692 * coffread.c: Undo minor damage done by Rich Pixley. Use
1693 different internal and external representations of COFF
1694 data structures. Use new BFD routines for swapping them in and
1696 * symfile.c (free_named_symtabs): Avoid freeing file names that
1697 are null or empty. Old i960 tools seem to produce files that
1698 claim to have empty names, causing each successive file read
1699 to blow away the previous one.
1700 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1701 Move deferred_stores to top of file, but don't separate its
1702 #define's from its variable. Add commentary.
1703 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1704 favor of keeping the (working) config.gdb. Move readline
1707 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1709 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1711 * infptrace.c (fetch_registers): no result, since now void.
1712 * tconfig/news: target depends on m68k-tdep too.
1714 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1716 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1719 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1720 applied various small fixes due to or inspired by RMS comments
1722 * doc/gdb.texinfo: finished using all RMS comments, save those for
1723 appendices on readline and cmd history (which are in other source
1726 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1728 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1729 chapter 9; (2) documented 'break' command's menu mode for
1730 overloaded names, in response to hgs problem report C++ p-31
1732 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1734 * doc/gdb.texinfo: (1) better introductory example; (2) more
1735 consistent use of @code, @samp, @file, @kbd throughout; small
1736 cleanups to first three nodes; (3) new "Contributors" node;
1737 (4) Appendix, Renamed Commands; (5) divert specialized startup
1738 instructions to "Targets" chapter for generic manuals, while
1739 leaving them up front for manuals specific to specialized
1740 environments; (6) apply fixes from RMS comments through chapter 4.
1742 * pretex.m4: modify explanatory text slightly (and redefine
1743 "regexp") to keep GNU m4 from complaining. (It still crashes
1744 later, but one step at a time...)
1746 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1748 * readline/readline.c (update_line): Avoid dereferencing a pointer
1749 before comparing it to its bounds. Saber caught this.
1750 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1751 and only set PC if tgetstr returned non-null. Saber caught this.
1753 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1755 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1756 stuff for config manual) here where it counts; updated
1757 to use new subdir structure (gdb/doc/).
1759 * Makefile: generated from above via
1763 * gdbint.texinfo: added instructions on generating gdb.info* files
1764 locally for release. These are ordinary info
1765 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1766 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1767 to generate these, so we distribute them already formatted.
1769 * gdb.texinfo: included full Info node and menu crud (as generated
1770 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1772 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1773 put in comments-for-future gdb.info target (one day makeinfo will
1776 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1778 * gdb.texinfo: Updated to include new or old undocumented
1779 commands, at least the following (perhaps some others I forgot to
1780 record): info f, info float, info path, info program, info s, info
1781 set, info source, info terminal, info types, info user, set/show
1783 Also covered all recent GDB command renames for v4.
1785 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1787 * mipsread.c: Rather than keeping count of how many symtabs
1788 and psymtabs we have, for sorting purposes, count them when
1789 we need to sort. This fixes bug in rereading of symbol tables.
1791 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1793 * infcmd.c: renamed "info path" to "show paths"

1804 Fix up "saber_gdb" to work again.
1805 * saber.suppress: Update.
1807 * coffread.c, exec.c, infptrace.c, inftarg.c, remote.c, solib.c,
1808 symtab.h, target.c, target.h: Lint.
1809 * core.c: setup and select frame after reading shared libs,
1810 else reading shared libs will clobber them. Lint.
1811 * utils.c (error): Force out any buffered wrap text.
1813 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1815 * remote.c: Remove decls of memory_insert_breakpoint
1816 and memory_remove_breakpoint, no longer used. (Suggestion of
1819 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1820 to make it easier to interface to "configure"'d libraries.
1822 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1824 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1825 aliases for set/show print.

1877 dc_dcontext_t not int.
1879 * coffread.c [TDESC]: Use system include files not <intel-coff.h>.
1881 * coffread.c [TDESC]: Move setting of debug_info from
1882 coff_symfile_read to find_linenos and make it work with BFD.
1884 * cplus-dem.c [__STDC__]: Make x{m,re}alloc return void*.
1886 * signame.c: Cast const char* to char* when assigning to sys_siglist.
1888 * utils.c (strsave): Make arg const char* not char*.
1890 * infrun.c (wait_for_inferior) [SHIFT_INSN_REGS]: Use

1911 Mips bringup and general cleanup
1913 * cplus-dem.c: Move CPLUS_MARKER define to after defs.h.
1914 * infptrace.c (PT_WRITE_D, PT_READ_D): Use correct values.
1915 (This still doesn't seem to make MIPS bkpts work.)
1916 * mipsread.c: Remove dup "Reading symbol data..." msg.
1917 (symbol_file_command, add_file_command): Remove, obsol.
1918 * printcmd.c (ptype_command): Say "an enum" rather than "a enum".
1919 Wrap output appropriately.

1921 selected_frame rather than target_has_stack or coredumping.
1922 * valprint.c (type_print_varspec_suffix): Wrap "ptype" output of
1923 enums appropriately.
1925 Wed May 1 14:10:22 1991 Jim Kingdon (kingdon at cygint.cygnus.com)
1927 * signame.c: Include defs.h and param.h.
1929 * cplus-dem.c: Include defs.h and param.h.
1930 Makefile.dist: Don't hack in the "param.h".
1931 param.h: Don't include defs.h.
1933 * expread.y: Use a union to deal with the fact that type_stack
1934 can have both ints and enum type_pieces in it.
1935 ({push,pop}_type_int): New functions.
1937 Tue Apr 30 13:18:58 1991 Jim Kingdon (kingdon at cygint.cygnus.com)

1949 symtab.c, cplus-dem.c, value.h, expread.y, valprint.c,
1950 copying.awk, solib.c, inflow.c, symmisc.c
1951 : Lint. Use read_memory not read_memory_integer on CORE_ADDR's.
1952 Use {value_as,unpack}_pointer (added to values.c)
1953 not {value_as,unpack}_long on CORE_ADDR's.
1954 Use longest_to_int (added to defs.h) instead of cast to int.
1955 Remove from_tty arg to mod_path.
1956 Put symfile_bfd in {coff,dbx}read.c not symfile.h.
1957 Use OP_NULL instead of 0 where dummy enum exp_opcode needed.

2445 * i386-pinsn.c: Move #includes to top, remove useless ones.
2446 * i386-tdep.c: Don't bother including <.../reg.h> since we
2447 don't use it (and it doesn't exist on host systems).
2449 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2450 Convert negative numbers properly.
2451 (ieee_test): Make numbers really random; fix format arg.
2453 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2454 * core.c (core_detach): Unpush core_ops, which might not be on
2455 top. We used to just pop the top, which broke things. Don't
2456 need dont_repeat() any more.
2457 (core_file_command): Psst! Don't repeat it.
2458 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2459 * expprint.c (print_subexp): Avoid switch fallthru on
2460 BINOP_ASSIGN_MODIFY, so we can print += and such.
2461 * frame.h: Fix typo.
2462 * inflow.c (kill_command): After killing inferior, print our
2463 current frame in the core file, if we have one.
2464 (generic_mourn_inferior): When inferior dies, either select
2465 the current frame (in the new target, e.g. core file), or
2466 set both the current and selected frames to NULL.
2468 Changes from Peter Schauer.
2470 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2472 * Make all file names fit in 14 characters (sigh and damn!):

2481 mv remote-sa.m68k.shar rem-m68k.shar
2482 mv remote-multi.shar rem-multi.shar
2483 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2484 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2485 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2488 * command.c (user_info_1, user_info): New command for listing
2489 the user-defined commands.
2491 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2493 * dbxread.c (really_free_pendings): Clear file_symbols
2494 and global_symbols after freeing them; otherwise, running
2495 this function twice (if it appears twice on the cleanup
2496 chain), we try to free things twice.
2498 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2499 based on text_addr (the address of text in core), not on addr (the
2500 offset between text in the .o file and in core). This change
2501 is from Peter Schauer.
2503 * main.c: Define ALL_CLEANUPS as a cast of zero.
2504 (return_to_top_level): Use it.
2505 (main): Do all cleanups after each command run as part
2506 of the gdb startup sequence. Also do all cleanups before
2507 entering the command loop, and every time we exit the command
2508 loop and reenter. Before, the cleanups from the startup sequence
2509 were being left undone until the first error!
2510 (command_loop): Rename do_nothing cleanup to command_loop_marker
2511 so we can see it easily when examining the cleanup chain.
2512 (init_signals): Add another do_nothing for signal handling.
2513 (quit_command): Only try to kill target if it has execution.
2514 Problems in the target stack got us into a state where
2515 inferior_pid was nonzero but none of the targets had execution.
2516 In this state you couldn't exit gdb.
2518 * dbxread.c: Two changes from Peter Schauer.
2519 (echo_command): Fflush output after an echo command.
2520 (show_history): Pass all args to cmd_show_list.
2522 * utils.c (init_malloc): Call mtrace to turn on tracing
2523 if the environment variable MALLOC_TRACE is set to a file name.
2524 * mtrace.c: Add source file which provides a log of every malloc,
2525 free, and realloc to a trace file.
2526 * mtrace.awk: Add source file which analyzes the trace file.
2527 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2528 (VERSION): Roll to 3.94.3.
2530 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2531 (check_duplicates): Don't bother with watchpoints.
2532 (set_raw_breakpoint): Comment about danger of this routine.
2533 (watch_command): Parse and eval all args before calling
2536 * solib.c (find_solib): Avoid error in referencing memory to
2537 see if any more shared libraries have been added. This is
2538 particularly useful if the target has terminated. Bug reported
2541 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2542 in bringing up 3.94.2 on the Sun-3.
2544 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2545 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2546 expression (in scope) before reenabling watchpoint.
2547 * signame.c (init_sigs): Add missing declaration of i, fix
2548 sys_siglist declaration.
2549 * source.c (list_command): Fixed range computation to use
2551 * stack.c (backtrace_command): Do not allow command if target has
2552 no stack, print informative error message.
2553 * target.c (target_command): Do not write into command line
2554 because this fails if the target command is used in a user defined
2555 command. [This change was enhanced by gnu to support any-
2556 unique-prefix matching on target names.]
2557 * valops.c (value_struct_elt): Avoid infinite loop on an
2558 erroneous attempt to print the member of function (try p main.p).
2560 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2562 * expread.y (name_no_typename): Avoid reduce/reduce errors
2563 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2564 Since the GDB parser really doesn't use name_no_typename in a
2565 name-only context, the parser can't tell the diff between
2566 names and numbers here. Avoid allowing a name_no_typename
2567 to be a NAME_OR_*INT to resolve the conflict.
2569 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2571 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2573 * valprint.c (val_print_fields): bitfield printing didn't handle
2574 byte order. Indirect through a few more fns to cope.
2576 * values.c (modify_field): also cope with byte order.
2578 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2580 Cleanup for release 3.94.2:
2582 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2583 include files. Roll version to 3.94.2.
2585 * coffread.c (init_stringtab): Read length into unsigned char
2586 array before swapping; don't assume 32-bit longs.
2588 * target.c (target_info): Don't bother with get_sym_file, just use
2589 the symfile global variable.
2590 * symtab.h, symfile.c (get_sym_file): Delete it.
2592 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2593 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2594 (read_type): Replace one more error() with complain().
2596 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2598 * i960-tdep.c: Fix copyright attribution.
2600 * config.gdb: Quote all backquotes in doublequotes. You can
2601 quote me on that. BSD 4.4 shell found this one.
2603 * infptrace.c (throughout): The third argument to ptrace is an
2606 * infrun.c (wait_for_inferior): When program has terminated, we
2607 have to call target_terminal_ours before we pop that target off
2608 the stack (e.g. before a call to target_kill or
2609 target_mourn_inferior). This fixes problem where a program
2610 terminates, then GDB stops for (tty output) and you have to type
2611 "fg" to the shell to resume it. FIXME: This code for what to
2612 do after termination really should be in normal_stop instead.
2614 * gdbcore.h (read_memory_check): Change declaration; it changed
2617 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2618 4.4 prereleases, this avoids a bug in their sgtty compatability
2620 * remote.c: Use terminal.h rather than hand-rolling the same.
2622 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2623 * utils.c (strsave, strstr): Fix arg types.
2624 * valprint.c (val_print): lint
2626 MIPS symbol table support from Per Bothner:
2628 * symfile.c (symtab_fns): Remove initializer table that needs to
2629 be hacked for each new symbol file format supported.
2630 (add_symtab_fns): New function, chains symbol table
2631 handlers into the global list.
2632 (symfile_init): Search this list.
2633 * symfile.h: Add next pointer, declare add_symtab_fns.
2634 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2635 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2637 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2638 symbol *). Thus, we no longer need the hack to trash
2639 pst->filename. Good, since that hack confused code in symfile.c!
2641 (reorder_symtabs, destroy_all_symtabs): Removed static
2642 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2643 Instead, the latter now uses a temporary array (stack-allocated
2644 from an obstack, and then freed).
2646 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2647 haven't been set in the outermost stBlock of a procedure. This was
2648 a problem with f77 binaries on Ultrix 4.?.
2650 (new_symtab, new_symbol, new_type): Continue changing code to use
2651 obstacks more and otherwise conform to dbxread internal style.
2652 Made the free_code of symtabs be free_linetable (as in dbxread)
2653 instead of free_contents. This implies memory leaks when reading
2654 a new symbol table, until the conversion is finished. Did change
2655 (struct symbol) and (struct type) to be allocated on the
2656 symbol_obstack. Blocks and blockvectors are among the things
2659 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2660 tested much, but it solved one problem (reported by Meissner), and
2661 cleans up some other things. The problem happened when an
2662 included file contains actual code (functions) and not just
2663 definitions. The mips coff is a little inconvenient there, since
2664 it may cause a procedure to be mapped to the wrong psymtab.
2666 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2667 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2668 this will need work for the new core paradigm.
2670 Opcode patches from the net:
2672 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2673 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2674 missing altogether - they are added here. From Bruce Bauman.
2675 * mips-opcode.h: The low mask for C0 instructions was too small.
2676 From Garrett Lau. I modified the fix to check the entire 32-bit
2679 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2682 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2684 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2686 * dbxread.c (read_type): Pointer subtraction (value_sub in
2687 valarith.c) sometimes failed because the types of the
2688 pointers being subtracted were not identical.
2689 These differed because dbxread.c was allocating pointer types
2690 using dbx_alloc_type+smash_to_pointer_type instead of
2691 lookup_pointer_type. I failed to find a justification for the
2692 former, so I changed it to use the latter. Similarly, I
2693 replaced smash_to_function_type by lookup_function_type,
2694 and smash_to_reference_type by lookup_reference_type.
2696 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2697 _initialize_mipsread): corresponding changes.
2699 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2701 * source.c (mod_path): Do tilde_expand on each component of the path,
2702 rather than on the (list of) paths as a whole.
2703 (print_source_lines): Set first_line_listed in addition to
2704 current_source_symtab and current_source_line. If the source was
2705 not findable, after a "dir" command to fix the problem,
2706 a "list" would get the wrong lines.
2708 While I was there... (gnu):
2710 * dbxread.c (read_type): Change error to complaint.
2712 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2714 First attempt at detailed understanding of symbol table memory alloc.
2716 * dbxread.c (dbx_symfile_read): Free our string table if we
2717 aren't the mainline. Free the "info" struct since we're done with
2719 (init_psymbol_list): Free any previously allocated psymbol lists.
2720 (): FIXME: Should realloc-down the psymbol lists when done reading
2721 the main symbol file?
2723 * symmisc.c (free_symtab): Free fullname field too.
2725 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2726 (REGISTER_ADDR): Make result type unsigned int.
2728 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2729 define REGEX must also define REGEX1 (its dependency).
2731 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2733 * tconfig/i960: No longer works, points you at vxworks960 or
2736 * xgdb.c, XGDB-README: Remove file. Users can get the much
2738 * Makefile.dist: Remove all trace of xgdb.
2740 * breakpoint.c (breakpoint_1): Pass demangle arg to
2741 print_address_symbolic.
2742 (clear_breakpoints): Remove unused function.
2743 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2744 (breakpoint_re_set): Use catch_errors to do them all anyway.
2746 * gdb-int.texinfo (Host versus Target): Add section on what is
2747 a "host" feature versus what is a "target" feature.
2749 * infcmd.c (path_command, path_info): Handle the PATH variable
2750 (object search path) as conveniently as the source search path.
2751 * environ.c (set_in_environ): Set some vars in GDB's environment,
2752 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2753 * source.c (mod_path): New function, from guts of
2754 directory_command, modifies a path. Used by path_command.
2755 (directory_command): Call it.
2756 * defs.h (strsave): Declare.
2758 * utils.c (sevenbit_strings): Add new printing option.
2759 (printchar): Use it.
2760 (strsave): Provide this handy helper routine.
2761 (set_width_command): Rename set_screen_width_command.
2762 (_initialize_utils): "set screen-width" => "set width";
2763 "set screen-height" => "set height"; add sevenbit-strings.
2765 * infcmd.c (do_registers_info): Print floating point registers
2766 in raw hex as well as float format, regardless of whether it is
2767 a "virtual" convertible register.
2768 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2769 regs as a double, just in case it's being used that way.
2770 * values.c (unpack_long): Comment on array/function coercion.
2771 (unpack_double): Argument is in target byte order now. For
2772 integer arguments, just call unpack_long and float the result.
2773 * m68k-tdep.c: include defs.h for "const" handling.
2774 * remote-nindy.c: Use ieee-float stuff.
2775 (nindy_fetch_registers): Unpack double regs to host double, then
2777 (nindy_store_registers): Pack extendeds to host double, flip
2778 around by misusing unpack_double, send as target double.
2780 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2781 zero, as when stopped at the first instruction of a process.
2783 * blockframe.c: Fix filename in comment (param.h => tm.h).
2784 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2785 * tm-68k.h: Fix typos.
2787 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2789 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2791 * coredep.c (fetch_core_registers): Pass end-address of register
2792 section to register_addr as expected. Don't call supply_register
2793 if we'd just pass it garbage.
2795 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2797 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2799 * target.c (push_target, target_info): Cast enums to int for < or
2802 * stack.c (print_frame_info): Identify source file & line
2803 even if we can't print it.
2805 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2807 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2809 Clean up IEEE floating point support.
2811 * ieee-float.h: New file.
2812 * ieee-float.c: Write real routines to convert between host
2813 doubles and various target IEEE extendeds.
2814 * m68k-xdep.c: Eliminate assembler code for extended floats.
2815 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2816 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2817 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2818 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2819 double_to_ieee_extended.
2820 * i960-tdep.c: Define ext_format_i960.
2821 * m68k-tdep.c: Define ext_format_68881.
2822 * sparc-tdep.c: Define ext_format_sparc, though unused.
2823 * Makefile.dist (HFILES): Add ieee-float.h.
2824 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2827 Obsolete the "coffstrip" program in favor of using BFD's strip.
2829 * nindy-share/coffstrip.c: Remove file.
2830 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2831 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2832 * tconfig/nindy960: Remove reference to coffstrip.o.
2834 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2836 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2838 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2839 * dbxread.c: Remove static symfile_bfd.
2840 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2842 * inftarg.c (child_detach): Pop the child_ops vector if the
2843 detach is successful.
2844 * remote-nindy.c (nindy_create_inferior): Don't push a new
2845 nindy_ops since nindy uses the same one for execution and memory
2847 * core.c (core_ops): Use child_attach and child_create_inferior
2848 rather than default attach and create_inferior functions.
2850 Handle floating point registers in core files.
2852 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2853 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2854 This version untested since BFD doesn't yet support sun3 core
2856 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2857 conventions. Fix comments and style. This version has not
2858 been compiled yet, since we have no HP inhouse.
2859 * core.c (get_core_registers): Look for two sections, ".reg"
2860 and ".reg2", and pass both to fetch_core_registers sequentially.
2862 Revise directory path yet again.
2864 * source.c (forget_cached_source_info): Not static any more.
2865 (init_source_path): New default source path is "$cdir:$cwd".
2866 (dir_command): Handle variable arguments ($cdir, $cwd).
2867 (source_info): Print "Compilation directory" rather than
2868 "Originally compiled in" to remind people of $cdir.
2869 (openp): If the path contains $cwd, use current directory.
2870 (open_source_file): If compilation directory is known, replace
2871 first $cdir in path with the compilation directory.
2872 (print_source_lines): Even if we can't print the lines, set the
2873 current symtab and line for future commands like "info source" or
2874 "breakpoint". Also, error message now contains the file name,
2875 line number, and file access error message.
2876 (_initialize_source): Fix help text to describe changes.
2877 * main.c (cd_command): Forget cached source info when we chdir.
2878 * utils.c (strstr): Add simple implementation.
2880 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2882 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2883 Byte-swap COFF symbol tables if necessary when reading them in.
2884 Use complain() to replace error message in one spot. Needs
2885 corresponding change in bfd/coff-code.h to make some symbol
2886 swapping routines non-static.
2888 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2890 Merge changes from Eirik Fuller, for UTek.
2892 * defs.h (errno): Add declaration.
2893 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2894 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2895 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2896 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2897 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2898 declarations of errno.
2900 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2902 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2903 <rpc/rpc.h> and <rpc/types.h>.
2905 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2907 * i960-tdep.c (examine_prologue): Add new argument limit,
2908 which stops the scan at the end of the prologue, or at the PC.
2909 This fixes a problem where it walks down into the code for the
2910 user's statements if that code looks like function prologues.
2911 Mark Fox and I have been bouncing this code back and forth, making
2912 small changes to it. Callers changed to match.
2914 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2916 Cleanup for gdb-3.94 release final:
2918 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2919 the .c files from vx-share and nindy-share, from the various
2920 macros, since they are not found via ALLDEPFILES.
2921 (SFILES): Add tm-i960.h.
2922 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2923 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2925 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2926 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2928 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2930 * am29k-tdep.c: Add contribution line.
2931 (examine_prologue): Cache information about function prologues in
2932 the misc-function-vector to avoid lots of references over the
2933 serial line while examining instructions.
2935 * core.c (core_close): New function made from cleanup_core.
2937 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2938 remote-vx.c, remote.c, target.c, target.h,
2939 Update target_ops vector to add attach, close, and load entries.
2940 Use add_syms_addr_command, not add_file_addr_command, for
2941 add_file. Break out close routine from existing code.
2943 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2944 they are in an obstack.
2945 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2947 (define_symbol): Add symbol type parameter; change callers;
2948 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2949 it to influence the symbol class on the i960.
2950 (define_symbol): Swap LOC_CONST's into target byte order.
2952 * exec.c (exec_close): New function.
2953 (exec_file_command): Call it.
2955 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2956 Fix byte order of frame pointer.
2957 (read_var_value): Result of 0 if var's value can't be found,
2958 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2959 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2960 (locate_var_value): Use read_var_value and use its lazy address
2961 as the location of the var's value. Lint.
2963 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2966 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2967 obsolete Intel versions in favor of vxgdb versions.
2968 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2969 code dealing with byte order of values, which Intel did in host byte
2970 order rather than gdb-4's target byte order.
2971 (i960_frame_chain_valid): Move to nindy-tdep.c.
2972 (examine_prologue, skip_prologue, frame_find_saved_regs,
2973 frame_args_address, leafproc_return, saved_pc_after_call,
2974 pop_frame): Add vxgdb versions from Mark Fox.
2975 (examine_prologue, frame_struct_result_address): Add code
2976 to deal with the saved value of G13 (struct return address
2978 (frame_args_address): Modify Mark's version to prefer the
2979 saved value over the current value in the topmost frame.
2980 Cache result in the frame info to avoid performance hair in
2982 (print_fault): Add gdb960 code for printing faults.
2983 (_initialize_i960): Actually call check_host.
2985 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2986 add stub routines. FIXME, these currently just return zero!
2988 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2989 (attach_command): Call target_attach, not target_open, now.
2991 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2992 (child_attach): Rename from child_open.
2993 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2994 don't confuse it with a zero step_resume_break_address.
2996 * inftarg.c (child_detach): Eliminate inferior_pid test.
2997 (child_files_info): Clean up message a bit.
2998 (child_ops): Use child_attach, not child_open, to attach.
3000 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
3001 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
3002 findvar.c to here, since it depends on the contents of the
3003 shadow_contents of breakpoints, but keep if #if 0 since it is
3006 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
3009 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
3010 (ptype_command, display_command): Eliminate have_inferior_p and
3011 have_core_file_p in favor of target_has_stack or
3012 target_has_execution.
3013 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
3014 code for actually finding the values of arguments, though we still
3015 keep track of the maximum stack offset for use in printing unnamed
3016 arguments. Handle missing FRAME_ARGS_ADDRESS.
3018 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
3019 (struct nindy_regs): Define registers passed to/from nindy.
3020 (nindy_fetch_registers, nindy_store-registers): Translate between
3021 nindy and GDB formats for the registers.
3022 (dcache_init): Statically allocate the cache, since it was being
3023 allocated by a malloc that was never freed anyway.
3024 (nindy_create_inferior): Error, not core dump, if no exec file.
3025 (nindy_before_main_loop): Use target_load, not target_add_file.
3027 * remote-vx.c (net_load): Specify large timeout for load
3028 requests. Allow user to break out with INTERRUPT.
3029 (net_break): Remove useless code, clean up. Change callers.
3030 (parse-args, skip_white_space, find_white_space): Clean up arg
3031 parsing to cope with quoted strings.
3032 (net_wait, net_quit): Never call error, just return status.
3033 (vx_read_register, vx_write_register): Cleanup status checking.
3034 #ifdef the code based on which CPU we are using (960 or 68k),
3035 FIXME, this should be completely general but it isn't yet.
3036 (vx_xfer_memory, vx_resume): Cleanup status checking.
3037 (vx_run_files_info): Improve message.
3038 (vx_load_command): Renamed from vx_add_file_command. Allow load
3040 (net_ptrace): Remove unused routine.
3041 (vx_wait): Adopt code from vxgdb960 to cope with broken
3042 connections to target machine and prompt to disconnect. Remove
3043 debug printouts. Map some EVENT_'s to SIGnals.
3044 (add_symbol_stub, vx_open): Print names of object files we found,
3045 and "ok" if we read their symbols OK. Clarify output in general.
3046 (vx_attach, vx_detach, vx_kill): Add these commands.
3047 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
3048 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
3049 "info files" output, and create_inferior, since we already have
3052 * stack.c (frame_info): Replace Frame_unknown with 0.
3053 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
3054 (return_command): Pop until the PC matches as well as the FP,
3055 so it works even if the FP is shared with another function,
3056 as in "frameless" or "leaf" procedures.
3058 * symfile.c (load_command): renamed from add_file_target_command.
3059 (add_syms_addr_command): renamed from add_file_addr_command.
3060 (add_syms_command): Stub to call target_add_syms.
3061 (_initialize_symfile): Change command names and descriptions,
3062 add-file => add-syms, and load from alias to its own command.
3064 * target.c (kill_or_be_killed, maybe_kill_then_attach,
3065 maybe_kill_then_create_inferior): Default for attempts to start
3066 a process, if one is already running, is to ask about killing
3067 it and retry if yes.
3068 (upstack_create_inferior): #if-0 it, strata obsolete it.
3069 (push_target, unpush_target, pop_target): to_close() a target
3070 before unstacking it.
3071 (target_info): Renamed from target_files_info.
3072 (_initialize_targets): Rename "i files" as "i target", accessible
3075 * target.h: Improve comments about the target_ vectored routines.
3077 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
3078 Convert commenting style to standard GNU style.
3079 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
3080 (SKIP_PROLOGUE): No longer a no-op.
3081 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
3082 (*_REGNUM): Sort register numbers.
3083 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
3084 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
3085 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
3086 are now 10 byte extendeds, not 8 byte doubles.
3087 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
3088 for nindy versus vxworks targets. FIXME, this should possibly go
3089 in the target vector.
3090 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
3091 frame_saved_regs and arg pointer with each frame.
3092 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
3093 (FRAME_ARGS_ADDRESS): Use cached result.
3094 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
3095 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
3096 (PRINT_RAMDON_SIGNAL): Call print_fault.
3097 (POP_FRAME): Now works.
3099 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
3100 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
3101 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
3102 (ADDITIONAL_OPTION_HANDLER): use target_load, not
3105 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
3106 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
3108 * valarith.c (value_subscripted_rvalue): Avoid handling
3109 floats and doubles specially; it gave alignment errors. Lint.
3111 * valops.c (value_of_variable, value_of_this): Error if unknown
3114 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3115 to avoid alignment problems.
3116 (value_print): Handle unknown value address.
3117 (cplus_val_print): Two args are ignored; remove them. Change caller.
3118 (val_print): Use unpack_long rather than pointer-deref.
3121 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3122 to avoid alignment problems.
3123 (value_being_returned): Error if return value unknown.
3124 (set_return_value): Add bogosity warning, FIXME. *
3126 * TODO: A woman's work is never done.
3128 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3129 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3130 Add ieee-float.o to OBS.
3131 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3132 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3133 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3135 Changes to generalize the VxWorks RPC protocol slightly, to handle
3136 i960 as well as 68000.
3138 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3139 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3140 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3141 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3142 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3143 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3144 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3145 so they will move in target byte order rather than network
3146 byte order (happens to be the same).
3148 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3150 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3152 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3155 Add contribution lines to various files, showing where they
3158 * breakpoint.c (break_insn, check_break_insn_size,
3159 read_memory_nobpt): Remove to mem-break.c.
3161 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3164 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3165 entry has bad register number. This change is not
3166 tested in this release, FIXME.
3168 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3171 * value.h: Force value's contents field to be aligned to hold
3172 at least a double or a long long (if supported). This avoids
3173 doing bcopy's in and out of the contents field.
3175 (step_1): Avoid coredump under obscure circumstances when we
3178 * symtab.h (misc_info): Add field to misc function vector for
3179 any kind of cached information the target code desires. AMD
3180 29000 uses this to avoid repeating examine_function_prologue's.
3182 * coffread.c: Lint. Remove static symfile, read_section_header.
3183 core.c (have_core_file_p): Lint: remove.
3184 expprint.c (print_subexp): Lint.
3185 infptrace.c, valops.c, valprint.c: lint.
3187 Roll in changes from vxgdb-5.0.1:
3189 * symtab.h: Comment byte order of each address class. Add
3190 LOC_LOCAL_ARG for frame-relative args (960).
3191 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3192 symtab.c, symmisc.c: ditto.
3194 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3196 * remote.c (remote_resume): Error if resume with a signal.
3198 * symfile.c (prim_record_misc_function): Clear misc_info.
3199 (fill_in_vptr_fieldno): Check stub type of arg.
3201 * valops.c (value_cast): Avoid looking up names of types whose
3202 name we don't know, to prevent coredump. Sun CC produces typedef
3203 rtx and the name of *rtx is zero...
3205 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3207 Roll in changes from final AMD 29000 port (Tiemann).
3209 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3210 for ../include/a.out.encap.h. This might not work now that BFD
3211 is separately compiled. Instead, BFD support for encap will have
3212 to translate machine type 29k into the right COFF_MAGIC.
3214 * infcmd.c: Remove references to inferior_pid that aren't used
3215 in actual ptrace calls; use target_has_execution, etc.
3216 (have_inferior_p): Remove function.
3217 (program_info): Print target info rather than "process number";
3218 avoid gratuitous messages unless from_tty.
3219 (run_stack_dummy, finish_command): Set proceed_to_finish.
3220 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3221 main.c: Lint. Lose have_inferior_p().
3222 inferior.h (have_inferior_p): Remove, lint.
3223 (proceed_to_finish): Add flag to ask that all regs be saved
3224 by normal_stop, for the few commands that need it, speeding up
3225 serial I/O. Add comments to stop_registers.
3227 * remote-eb.c: Remove newline from breakpoint message we grep
3228 for. Never time out when running the user program.
3232 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3234 Roll in changes from vxgdb-5.0.1:
3236 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3237 symbol in its raw form, we are processing an unlinked ".o" file.
3238 See if the target environment has assigned it an address, using
3239 target_lookup_symbol (VxWorks does), and enter it into the symtab
3242 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3243 68k versions for a simpler version that assumes zero FP at bottom.
3244 Fixes bug of truncated stack reports.
3246 * target.h (target_lookup_symbol): Define this routine's args
3247 and result, finally.
3249 * target.c (nosymbol): Default routine for target_lookup_symbol.
3250 (target_default): Default lookup_symbol and call_function too.
3251 (files_info): Only print has_all_memory warning if a non-dummy
3254 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3255 vx_convert_from_virtual): If target does not have floating point,
3256 zero register "values", and avoid doing cross-net conversions.
3257 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3258 (vx_open): Rearrange code that attaches to target and reads
3259 symbols for all loaded modules, to work if some of the modules
3260 are not accessible. Add symbol_stub() and add_symbol_stub()
3261 as callbacks from catch_errors(). Allow connect attempt to be
3262 interrupted painlessly with ^C (FIXME, there are still some bugs
3263 if the interrupt happens during symbol reading.). Print
3264 final message with puts_filtered, since symbol messages are
3269 * main.c (catch_errors): Only print errstring if non-null.
3270 (command_loop): Avoid an ioctl per command to test ISATTY.
3272 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3273 (vx_xfer_memory): Return correct result!
3274 (vx_files_info): Indicate whether target has float or not.
3275 (vx_lookup_symbol): Complain, not error, if target gone.
3276 (vx_open): Print "Connected" msg before disabling immediate-quit.
3277 [FIXME: lookup_symbol and vx_open changes need testing.]
3279 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3280 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3281 contributor lines and update copyrights to 1991.
3283 Changes from an attempted H-PUX host port:
3285 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3286 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3287 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3288 * remote-vx.c: include <sys/time.h> for HPUX.
3289 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3290 "core_file_command" routine to BFD regime. May not work yet.
3292 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3294 * xgdb.c: Replace X10 version with some VJ version.
3295 (FIXME: Its copyright assignment is not on record.)
3296 * xgdb.c: Update include files to X11R4 (Xaw crud).
3297 (xgdb_display_source, create_text_widget): fix call to
3298 get_filename_and_charpos. Rewack source window stuff for X11R4
3299 (gleaned from include files, and "nm's" of binary libraries, since
3300 I had no doc available).
3301 (append_selection, append_selection_word): Disable with FIXME
3302 since R4 changed interface here.
3303 (create_buttons): Add back the old set of buttons.
3304 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3306 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3307 Roll VERSION to 3.94 (not yet final though).
3309 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3311 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3312 obstack_int_grow, obstack_int_grow_fast): Eliminate
3313 cast on left of assignment, which gives MIPS cc fits and is
3316 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3317 F_ALIAS. Use printf, not fprintf, when not passing a file
3319 (compare_opcodes): Check that identical instructions have
3320 identical opcodes, complain otherwise.
3322 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3323 was reported by Roland McGrath.
3324 (unimp): Only match if exactly zero instruction. (Roland)
3325 (branches and traps): Generate all variations of these
3326 instructions with macros, based on a single call that defines
3327 each condition name and its binary representation.
3328 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3330 * valprint.c (val_print_fields): Take, and use, format parameter.
3331 This means that "p/x struct" again prints the elements in the
3332 desired format. Changed callers.
3334 * stack.c (frame_info): Use filtered output, and indicate wrap
3335 points. Remove kludgy formatting designed to avoid line wrap.
3337 * utils.c (wrap_here): If the line is already full (because
3338 we had printed a long indent or long wrapped string), do an
3339 immediate newline-and-indent.
3341 * m68k-pinsn.c (print_insn_arg): Bugfix from
3342 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3343 instruction is incorrectly disassembled as bkpt #8.
3345 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3346 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3347 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3348 and then will dump core (sometimes). I traced it back to an
3349 uninitialized symfile_name in psymtab_to_symtab.
3350 (const_vol_complaint): Add quotes to message.
3351 (define_symbol): Only believe line number if gcc_compiled.
3352 Avoid allocating symbol if we will not return it.
3354 Add target strata support so that newly established targets go
3355 into their right place in the target stack (e.g. a new exec file
3356 doesn't wipe out the ability to access the running process).
3358 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3359 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3360 and initialize it properly in all the targets.
3362 * target.h: Document strata. Change return type of push_target.
3364 * target.c (nomemory): new function for dummy memory access.
3365 (tcomplain): Rename complain, now also used in symfile.c.
3366 (push_target): Push targets within strata. New return value shows
3367 whether new target is on top of stack or not. Always keep dummy
3369 (target_files_info): Ignore dummy target.
3371 * core.c (core_open): Warn user, and skip accessing file, if the
3372 core target is not the topmost target in the stack.
3373 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3376 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3377 target_ops, it doesn't belong there since we have no regs there.
3378 Change name of target from machine => memory to clarify.
3380 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3382 * Freeze version 3.93 for release.
3384 * Makefile.dist: Handle vx-share and nindy-share subdirs
3385 properly when building gdb.tar.Z.
3387 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3388 printed in various places, so I could change just one copy.
3390 * dbxread.c, coffread.c: Change references to bfd->iostream
3391 to cast to FILE *, now that BFD avoids needing types defined
3392 in other header files.
3394 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3396 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3397 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3398 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3399 (actually gcc -Wall).
3401 * dbxread.c: Remove first_global_sym, last_global_sym, since
3402 they are never referenced.
3404 * defs.h (baud_rate): Declare.
3405 main.c: Define it, and add the -b option to set it.
3407 * gdb-int.texinfo: Add text on how to define a new host or target
3408 architecture, prompted by Per Bothner's questions about MIPS
3411 * gdb.texinfo: Document "complaints". Change doc of -q since
3412 gdb no longer prints the copyright and blurb if you specify a file
3413 name to be debugged (just like Emacs). Add doc for Nindy-specific
3414 command line flags for specifying target serial port and such.
3415 Update copyright to 1991.
3417 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3418 has taken over for us the job of ripping up executable files. The
3419 crud caused Per Bothner's port to not compile.
3421 * infrun.c (normal_stop): Avoid printing "Program exited
3422 normally" if we are in batch mode. This allows a GDB which
3423 executes a program on a target system, to behave like a Unix
3424 command (input from stdin, output to stdout, no extraneous
3427 * main.c (main): Allow additional machine-dependent command line
3428 options to be specified with the ADDITIONAL_OPTIONS,
3429 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3430 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3431 processing to occur just before the main loop with
3432 BEFORE_MAIN_LOOP_HOOK.
3433 (main): If a "core file" argument is specified, and it is not a
3434 core file, try it as a process ID to attach.
3435 (symbol_completion_function): Attempt to cope with
3436 "show screen-" TAB, not very successfully. This needs more work,
3438 (batch_file): New function, returns whether we are reading
3439 commands from an interactive tty on stdin, or from somewhere else.
3440 Called by normal_stop since it doesn't get from_tty passed down
3441 to it like many commands do.
3443 * remote-nindy.c: Handle command line options for nindy
3445 (nindy_before_main_loop): Prompt user for tty name if they
3446 don't specify it before getting to the interactive command loop.
3448 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3449 and -r command line options. Also add hook before main loop
3450 to make it easy to specify a tty.
3452 * TODO: More things to do, one done.
3454 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3456 * dbxread.c: Make complaint() calls pass pointer, not struct.
3457 Add complaints about badly formatted C++ type information
3458 (const/volatile indicator, and parse errors resulting in
3459 error_type). Fix C++ virtual member fn comment.
3460 (read_struct_type): Avoid bumping pointer if we got a parse
3461 error; this prevents our walking beyond the end of a string.
3462 Terminate loop on null char as well as semicolon.
3463 (process_one_symbol): Fix the LBRAC fix so that it uses the
3464 last previous SLINE, FUN, or SO record's PC address. C++ debug
3465 symbols did not have SLINE records in a useful order compared
3466 to the LBRAC records.
3467 (define_symbol): Handle "catch" records.
3469 * symtab.c (check_stub_type): Added new complain
3470 `stub_noname_complain' and added a consistency check to
3471 keep the debugger from crashing when finishing from an
3472 exception frame. A real fix will be needed later.
3474 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3476 * infcmd.c (attach_command): Make global.
3478 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3479 but make them easy to comment out. Perhaps later they should
3480 be enabled by what CPU you configure for? FIXME.
3481 (VERSION): Roll to 3.93.
3482 (pinsn.o): Remove rule for obsolete file.
3483 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3485 Run down a problem that manifested by printing the wrong function
3486 name in stack traces of read_ofile_symtab. Turned out that the
3487 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3488 the LBRAC symbol with an address in the *data* segment, which
3489 blew our binary search through the blocks.
3491 * dbxread.c: Use the complain() facility consistently to bitch
3492 about problems in the symbol file we are reading.
3493 (finish_block): Add code to check the nesting of the blocks;
3494 complain and Procrust them to fit if wrong.
3495 (make_blockvector): Check the order of the blocks, complain
3496 [but don't cope] if wrong.
3497 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3498 symbols to be sure their PC value is greater than the last SLINE
3499 (line number) symbol we've seen, complaining and adopting the
3500 SLINE PC value if wrong.
3502 * symfile.h (struct complaint, complaint_root, complain,
3503 clear_complaints): Add.
3504 * symfile.c (complain, complaint_root, clear_complaints): Add
3505 facility to deal with non-fatal complaints and to regularize their
3507 (symbol_file_add): Clear complaint counters to allow new complaints.
3508 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3510 * dbxread.c (dbx_symfile_read): Remember the address and size
3511 of the string table for the main symbol file, so we won't read it
3513 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3514 to avoid reading the string table yet again. Lint.
3515 (throughout): Improve filtered output, including word wrap.
3516 (read_range_type): Improve Bothner's fix to handle other types too.
3518 * utils.c: Improve line wrap implementation. Handle unlimited
3519 width by making chars_per_line unsigned.
3520 (puts_filtered): New, easy, function.
3522 * defs.h (puts_filtered): add.
3524 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3525 call the identical sort_symtab_syms() in symfile.c instead.
3527 * expread.y: Suggest the `file' command rather than `symbol-file'.
3529 * command.h (enum var_types): Add zinteger for seroable
3531 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3532 nested if's into a switch.
3534 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3535 we did not stop because of a breakpoint (it must have been for
3536 some other reason, like a "stepi"), so don't print anything.
3538 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3539 doesn't include <sys/types.h>, old SunOS's require it for
3542 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3544 A test port of gdb-3.92.6 to the Sony NEWS.
3547 Don't normally link in remote- or vx stuff.
3548 Some of it doesn't compile, and it wastes space for 99% of the users.
3549 Remove reference to no-longer-used HAVE_VPRINTF.
3550 Fixed BFD_DEP typo to BFD_DIR.
3552 Fix cast in arg to bfd_h_getlong.
3553 Make char *prefix be const.
3554 Fix how certain range types are mapped into builtin unsigned int types.
3556 Remove 2 #includes. They cause errors (on Sony, at least),
3557 and aren't needed (they wern't in earlier versions).
3559 print_address_symbolic should never demangle labels
3560 (since it prints *assembler-level* labels).
3562 [This was superseded by the change to printcmd below.]
3565 Add some "volatile" return types to avoid warnings.
3566 If MISSING_VPRINTF add vprintf function and not just macro
3567 (since vprintf is used in printcmd.c).
3569 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3570 (The latter isn't grokked by some PCC-based compilers.)
3572 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3574 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3575 * nindy-share/coffstrip.c
3576 Added some forward declarations (otherwise, gcc complains
3577 about implicit extern redefined as static).
3579 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3581 Changes inspired by Per Bothner:
3582 * printcmd.c (print_address_symbolic): Take additional parameter
3583 specifying whether to demangle.
3584 (print_address): Pass in asm_demangle to control demangling.
3585 (print_address_demangle): New fn, takes explicit arg to control
3587 * utils.c: Add new vars demangle and asm_demangle, and let them
3589 (fputs_demangled): If !demangle, just print the argument.
3590 (fprint_symbol): If !demangle, just print raw symbol.
3591 * valprint.c (val_print): Call print_address_demangle rather than
3592 print_address, to cause demangling to depend on the global
3593 rather than assembler-level demangling setting.
3594 * WHATS.NEW, gdb.texinfo: Document.
3596 * main.c (show_command): Show all settings if no arg.
3597 (initialize_main): Make "info set" the same as naked "show".
3598 * command.c (cmd_show_list): Handle prefix commands in the
3599 list, and print the name of the setting as well as its English
3600 description and value.
3602 Allow gdb functions to specify where a line should wrap if it
3603 exceeds the size of a terminal line. Use it to make the output
3605 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3606 of the right size when screen width changes.
3607 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3608 (wrap_here): New fn, indicates a point in the output where we
3609 should wrap the line rather than just letting it overflow at a
3611 (fputs_filtered): Implement wrapping.
3612 (n_spaces): New fn, returns a pointer to N spaces.
3613 (print_spaces_filtered): Use n_spaces.
3614 * defs.h (n_spaces): Declare.
3615 * stack.c (print_frame_info): Wrap with 4-space indent after
3616 fn name and before filename and line number.
3617 * printcmd.c (print_frame_args): Wrap with 4-space indent
3618 before each argument name is printed.
3619 * valprint.c (value_print): Wrap with no indentation before
3621 (val_print_fields): Wrap with indentation relative to nesting
3622 level before each field name.
3623 (val_print): Wrap with nesting indentation before array elements.
3624 * command.c (do_setshow_command): Avoid extra newlines,
3625 wrap with 4-space indent around values printed, end with period.
3626 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3628 * breakpoint.c (breakpoint_1): Implement addressprint for
3629 "info breakpoints" display. Change file name and line number
3630 format to " at file:nnn" rather than " (file line nnn)".
3631 * gdb.texinfo: Document.
3634 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3636 Frozen for gdb-3.92.6 release.
3638 README, WHATS.NEW: Update for 3.92.6 release.
3640 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3641 coffread.o from configs since it is now built by default.
3642 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3643 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3644 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3645 from configs since it is now built by default.
3647 Makefile.dist: Update for release 3.92.6. Handle files that
3648 have been moved to ../include, ../getopt, or ../bfd. Add
3649 saber.suppress and tests directory. Add config.status to
3650 the release (it will say "none").
3652 coredep.c: Minor formatting fixes.
3654 These changes were made in early December but only checked in now:
3655 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3656 nindy-share/nindy.c: lint
3657 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3658 register values coming back from the target; we store values
3659 in target byte order everywhere.
3661 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3663 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3665 * valprint.c (cplus_val_print, val_print_fields): New functions,
3666 which print C++ objects. They conspire to avoid printing a
3667 virtual base class more than once, following all the twists and
3668 turns of C++ virtual base rules.
3669 (val_print): Call the above rather than do it by hand.
3671 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3672 symbol file, not for added files like shared libs. This really
3673 needs to be generalized to a timestamp per file.
3675 * core.c (cleanup_core): Avoid coredump if no core file.
3677 * config.gdb: Accept -host or -target in place of +host or
3680 * coffread.c (find_linenos): Avoid desupported BFD interface
3681 to line numbers. We still read them manually rather than using
3682 BFD's "generic" features.
3684 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3686 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3688 * Makefile.dist: Eliminate use of $< in explicit targets.
3690 * readline/Makefile: Use $< rather than $*.c, which does not
3691 include the VPATH in GNU Make.
3693 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3694 copies of tconfig/i960, added for global configuration
3695 compatability. All i960 versions can read both coff and b.out.
3697 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3698 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3701 * TODO: Think of more things to do.
3703 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3705 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3706 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3707 64-bit float conversion.
3709 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3710 equivalent to sun?os4 so global config works.
3712 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3714 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3716 * main.c: Only declare linesize once; declare pagesize not at
3717 all, since it is never used.
3718 (main): Clear newly allocated line before it is used.
3720 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3722 Further stabilization for the Intel 960.
3724 * Makefile.dist: Parameterize the location of the "include"
3725 and "bfd" directories, as well as "getopt". Add symfile.c.
3726 Link in both dbxread and coffread. Fix up "make depend" to
3727 rewack the locations of include, bfd, and getopt in its output.
3729 * README: Document moving include files, improve some of
3732 * coffread.c: Move common code out to symfile.c. Change
3733 symbol_file_command style interface to use new *_symfile_init
3734 and *_symfile_read interface under BFD. Use BFD internal
3735 info to locate line table, symbols, etc.
3737 * core.c (core_fetch_registers): Rename to get_core_registers
3738 to avoid confusion with fetch_core_registers.
3739 (register_addr): Move to coredep.c, which is already machine
3740 dependent. This leaves core.c pretty clean of dependencies.
3742 * coredep.c (register_addr): Accept this routine from core.c.
3744 * dbxread.c: Move common code (with coffread.c, etc) into new
3745 symfile.c. Each psymtab now contains a pointer to the
3746 format-dependent function that knows how to read it in. Make
3748 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3749 (process_one_symbol): Add code to complain about a "compiler bug
3750 we muzzle here", if we actually see it.
3752 * eval.c (evaluate_subexp): Insert missing "break" statements
3753 in code that determines whether a variable is an lvalue in
3754 memory, register, or whatever. I detected this via a compiler
3755 bug in which it *almost* mashed out the whole switch statement.
3757 * gdb-int.texinfo: Add minor sections on configuring gdb for
3758 release, and about the README file.
3760 * infcmd.c (registers_info): Fix formatting somewhat. Still
3761 not as pretty as before, but it handles byte swapping.
3763 * remote-nindy.c: If data cache routines are interrupted while
3764 waiting for the remote end, be sure that any uninitialized cache
3765 blocks are on the free list, not on the valid list!
3767 * symfile.h: Flesh out this header file with all the various
3768 routines and variables that have been merged in from dbxread.c
3769 coffread.c, and symtab.c to symfile.c.
3771 * symfile.c: New file, containing code common to dbxread.c,
3772 coffread.c, and some code from symtab.c. All generic code for
3773 reading symbol files should be in here now.
3774 (unrecord_misc_function): Remove unused function.
3776 * symtab.h: Remove file-reading things to symfile.h.
3778 * symtab.c: Remove file-reading things to symfile.c.
3780 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3781 to decode i960 fault types.
3783 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3784 target.c: Change type of the "resume" function from int to void,
3785 since its result was never used.
3787 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3789 * main.c: Replace "stupid" with "caution"; you now "set caution
3792 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3794 * infcmd.c (do_registers_info): Call val_print to deal with the
3795 byte order of the registers being printed. FIXME, this makes
3796 the formatting of the output uglier.
3798 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3799 defined, call it for signals the debugger doesn't itself use.
3800 The i960 uses this for more detailed fault information.
3802 * remote.c (remote_open): If arg is null, print help rather than
3805 * sparc-xdep.c (register_valid): Avoid declaring size, since
3806 various modules will think of various sizes depending on the
3807 architecture of their tm-file. FIXME, we need protection against
3808 actually entering one of those modules, which would clobber
3809 storage if not for the target architecture compiled into gdb.
3811 * stack.c (up_command, down_command): Always print the frame
3813 (up_silently_command, down_silently_command): New commands
3816 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3818 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3819 more parameters than it used to.
3821 * findvar.c (registers): Increase slop to 256 bytes, which should
3822 protect us against even most RISC machines with large register
3824 (locate_var_value): Move declaration inside related ifdef.
3826 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3827 throughout, to avoid throwing away buffered input from the board.
3828 (nindy_wait): Supply_register takes addr_of_value, not value.
3829 (i960_print_fault): Renamed from i80960_fault.
3830 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3831 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3833 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3834 we can set the PC in the call to proceed(). Unpush nindy_ops
3835 before pushing it on top, to avoid message to user. Eliminate
3836 commentary from Unix machines that just misleads here.
3837 (reset_command): Fix error message to suggest target command.
3839 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3841 Release 3.92.5 as frozen.
3843 Stabilize the merged release...with help from lint, Saber C,
3846 Everywhere: Add include files needed to declare return types
3847 of functions called.
3849 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3851 * breakpoint.h: Add undeclared breakpoint functions, and some
3852 functions for display handling since I couldn't think of a better
3855 * breakpoint.c (insert_breakpoints): Make code for disabling
3856 shared library bkpts more likely to work. It's used when we
3857 rerun a program and stop before the shared library has been
3859 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3860 cast from pointer, so it squeezes through catch_errors.
3861 (bpstat_stop_status): Fix logic broken some time ago. We now
3862 always create a bpstat if the stop address matches a breakpoint,
3863 even if we don't stop there -- just like the old code used to do
3864 before I got my fingers into it (sigh).
3865 (breakpoint_1): Print "ignore count" after "stop only if"
3866 condition, since that's how it actually works.
3867 (mention): Handle watchpoints as well as breakpoints.
3868 (watch_command): use set_raw_breakpoint and mention to do most
3869 of the work (and initialize all the fields!). Only pass one
3870 arg to parse_c_expression, since that's all it takes.
3872 * command.c (not_just_help_class_command): Rename arg to args
3873 since we ignore "unused argument" warnings on vars named "args".
3874 inflow.c (child_terminal_info): ditto.
3875 infptrace.c (kill_inferior): ditto
3876 main.c (catch_errors, version_info, quit_command, pwd_command,
3877 source_command, dump_me_command, editing_info,
3878 set_history_size_command, set_history, show_history,
3880 stack.c (locals_info): ditto
3881 target.c (target_files_info): ditto
3882 valprint.c (set_input_radix, set_output_radix): ditto
3884 * core.c: Remove old variables for handling core and exec file
3885 sections (data_start, data_end, stack_start, stack_end,
3886 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3887 text_end, exec_data_start, exec_data_end, text_offset,
3888 exec_data_offset, data_offset, stack_offset). They're
3889 superseded the more general build_section_table and
3891 (get_exec_file): Mention the `file' command.
3892 (read_memory_check): Rename to memory_error, and only call it
3893 in the case of an actual error.
3894 (read_memory, write_memory): call memory_error.
3895 (core_fetch_registers): Register section name is ".reg".
3897 coredep.c: Remove a bunch of crud now that all this file does
3898 is pull the registers out of a core file.
3899 (fetch_core_registers): Rewrite to actually work, I hope.
3901 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3902 Replace index() with strchr(). Remove all the pre-BFD macro
3903 definitions for accessing the symbol file.
3904 (struct dbx_symfile_info): Encapsulate the information that
3905 dbx_symfile_init needs to pass to dbx_symfile_read in this
3908 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3909 dbx_symfile_discard): Rearrange symbol file reading to divide
3910 the format-specific part from the format-independent part,
3911 leaving the format-independent part such as file name expansion
3912 and opening in symtab.c. This replaces
3913 partial_symbol_file_open and partial_symbol_file_read.
3914 Symbol_file_read, add_file, add_file_target_command,
3915 add_file_addr_command move to symtab.c. Pass an explicit
3916 "mainline" flag for when reading the main symbol table, rather
3917 than relying on the offset address to be zero or nonzero.
3919 (dbx_symfile_read): Don't allow void *'s to be printed as
3921 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3922 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3923 macro" debug version really work.
3924 (read_dbx_symtab): Remove unref'd parameter inclink.
3925 Avoid swapping N_SLINE symbols, for speed.
3926 Merge N_TEXT!N_EXT case with the other external symbol
3927 definitions' case. Add comments.
3928 (start_psymtab): Allocate the symfile name in the psymtab on
3929 the psymbol_obstack, rather than using the caller's storage.
3930 (end_psymtab): Only allocate a dependencies list if there are
3932 (psymtab_to_symtab_2): Use BFD when reopening file to read
3933 its symbols for real.
3934 (read_struct_type): Add FIXME comments where it needs work
3936 (read_huge_number): Add FIXME about overflows.
3937 (read_range_type): Add FIXME about comparing a long to 1<<32.
3939 * coffread.c: Minor changes to move things closer to the new
3940 regime with symtab.c and dbxread.c Major work is still needed
3943 * exec.c (exec_file_command): Remove old variables (see core.c
3945 (xfer_memory): If memory transfer is right at the end of a
3946 section, don't lose.
3948 * findvar.c (get_saved_register): If value is in a real
3949 register, LVAL is lval_register, not lval_memory.
3951 frame.h: Declare print_sel_frame and record_selected_frame.
3953 gdb-int.texinfo: New file, for GDB internals documentation.
3954 Very simple, unformatted doc of cleanups is there for now.
3956 gdbcore.h: Remove obsolete variables that described a.out
3957 section addresses and offsets. (See core.c above.)
3958 Declare fetch_core_registers and registers_fetched.
3960 getopt.c: Declare char *alloca(); even on SPARC.
3962 infcmd.c (run_command): Call target_kill rather than
3964 (step_command, next_command, stepi_command, nexti_command):
3965 Declare from_tty parameter even though we don't use it.
3966 (run_stack_dummy): argument BUFFER is a char array, not
3967 a pointer to REGISTER_TYPE.
3968 (finish_command): using_struct_return needed a value *,
3969 not a struct symbol *.
3971 * infptrace.c (child_xfer_memory): To avoid dependency on
3972 where sections are in memory, try PT_WRITE_D and if that fails,
3973 try PT_WRITE_I. Most Unixes don't care which you use.
3975 * infrun.c (step_resume_break_shadow): Change to array to
3976 match other breakpoint shadow storage.
3977 (clear_proceed_status): Pass address of bpstat to
3978 bpstat_clear, not the bpstat itself.
3979 (child_create_inferior): FIXME comment about if the child
3981 (start_inferior): Remove old function.
3982 (child_open): Use target_kill rather than kill_inferior.
3983 (wait_for_inferior): Ditto.
3984 (insert_step_breakpoint, remote_step_breakpoint): Use
3985 new step_resume_break_shadow.
3987 * inftarg.c (child_wait): If all child processes die,
3988 pretend that the one being waited for exited with signal 42.
3990 * main.c (command_line_input): When scanning for comments,
3991 don't coredump on unclosed quotes.
3992 (quit_command): Use target_kill rther than kill_inferior.
3993 (_initialize_main): Rename class_user from "user" to
3996 * printcmd.c (print_command_1): Initialize "fmt" if no format
3997 is specified by the user.
3998 (print_frame_args): Only add to args_printed if we are
3999 actually fetching args from the stack (avoiding undefined
4001 (_initialize_printcmd): Remove bogus \{ from string.
4003 * remote-eb.c (eb_open): Avoid coredump on no argument.
4005 * remote-nindy.c: Bring out of Intel environment into new
4006 target environment. Remove all conditional compilation on
4007 I80960. Massive hacking throughout.
4008 (nindy_xfer_inferior_memory): New routine stolen from
4010 (nindy_create_inferior): New routine pieced together, probably
4011 not quite working yet.
4012 (nindy_ops): New target_ops struct for nindy.
4014 * remote-vx.c: Use write_memory rather than target_write_memory
4015 to get error checking.
4016 (vx_add_file_command, vx_open): Use symbol_file_add rather than
4018 (vx_create_inferior): Use target_terminal_ours...
4020 * signame.c (_initialize_signame): Always initialize, since
4021 we need the table for things other than psignal.
4023 * solib.c (solib_add): Use symbol_file_add, not add_file.
4024 (solib_address): Return boolean result rather than struct
4025 pointer which nobody else knows the type of.
4027 * sparc-tdep.c, valops.c: Use write_memory rather than
4028 target_write_memory, to get error checking.
4030 * stack.c (locals_info, catch_info, args_info,
4031 get_selected_block, frame_command, up_command): Use
4032 target_has_stack, rather than have_inferior_p or
4035 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
4037 * symfile.h: New file, defining the interface between the
4038 generic and object-file-specific symbol reading code.
4040 * symtab.c: Move generic symbol-reading interface to symtab.c,
4041 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
4042 table to map BFD targets to symbol-reading modules in GDB.
4043 Change index to strchr.
4044 (lookup_struct_elt_type): Use error() rather than hand-made
4045 simulations thereof.
4046 (lookup_partial_symbol): Speedup slightly when length == 0.
4047 (symbol_file_add): New function.
4048 (symbol_file_command): Call it.
4049 (symfile_open, symfile_init): New function.
4050 (add_file_target_command, add_file_addr_command): moved from
4053 * target.c (target_command): use target_kill.
4055 * target.h (target_files_info): Don't declare, never called
4058 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
4059 files to determine stack end address.
4061 * valarith.c (value_x_binop, value_x_unop): Change error message
4062 to be more useful. Pass proper argument to value_struct_elt.
4064 * valops.c (value_assign): FIXME comment that long long
4065 bitfields will break here.
4067 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
4068 Update `make saber_gdb' to work better.
4070 * TODO: A woman's work is never done.
4072 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
4073 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
4074 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
4075 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
4076 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
4077 valops.c, valprint.c, exec.c: Lint.
4080 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
4082 Continuing Intel 960 port merge of GDB.
4084 * Makefile.dist: Merge i960 "nindy-share" files. Rename
4085 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
4086 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
4087 Wack over "make depend" so it handles files in subdirectories
4088 vx-share, nindy-share, bfd, and in the current directory.
4090 * blockframe.c (get_prev_frame_info): Remove fatal error
4091 if stack not defined.
4093 * core.c (core_open, core_detach): New functions that handle
4094 the old "core-file" command as "target core" and "detach" instead.
4095 (core_file_command): Call them.
4096 (core_xfer_memory): Use common routine xfer_memory.
4098 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
4099 dbxread now uses bfd for everything but symbol reading itself.
4100 BFD internals are used to drag out the relevant file offsets.
4101 (partial_symbol_file_open): Change args all around for BFD.
4103 * symtab.c: Rename "value" to "val" everywhere, so we can
4105 (symbol_file_command): New command, moved from dbxread.c
4106 and coffread.c. It uses BFD to read the file, then vectors
4107 based on its type, to dbx or coff symbol readers.
4108 * symtab.h: Extern a few vars for symbol_file_command.
4110 * target.h: Breakpoint takes a char * save area, not a char **.
4112 * valprint.c (val_print): When unpacking bitfields, offset
4113 the address in gdb of the value, if it is declared with a shorter
4114 type. Remove the last "runtime kludge test" of host byte order.
4116 * utils.c: Remove old my_bfd_read routine.
4118 * stack.c (frame_info): Use target_has_stack. Print program counter
4119 register's actual name rather than "pc", since it's called the
4120 "ip" (instruction pointer) on the i960 (sigh).
4122 * target.c (target_command): Add command for selecting a target
4123 type and calling its open routine. This is used for initiating
4124 communication with a particular target, in a generic way.
4126 * tm-i960.h: Update for modern gdb. Remove semicolons from
4127 various macros. Handle reading struct return convention, and
4128 error-out attempts to return structs with the "return" command.
4129 Be sure gdb doesn't think we know how to call functions in the
4132 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4133 to i960_xxx in lower case.
4134 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4135 not being defined yet.
4137 * remote.c (remote_open): Call start_remote to initialize
4138 wait_for_inferior during open.
4139 (remote_xfer_inferior_memory): Return length written rather
4142 * remote-vx.c (target_command -> vx_open): Use new generic
4144 * remote-eb.c, inftarg.c, exec.c: ditto.
4146 * infrun.c: Fix comments.
4147 (attach_program -> child_open): Use new generic target command.
4148 (wait_for_inferior): Clear saved register values before target_wait,
4149 so target_wait can set some of them if convenient.
4151 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4152 Return success indicator, not void.
4153 (child_xfer_memory): Avoid fetching initial word if we'll
4154 overwrite it anyway.
4156 * infcmd.c (attach_command): Use new generic target open routine.
4157 (_initialize_infcmd): Update doc on attach and detach commands.
4158 (do_registers_info): Merge in a byte-order problem as a FIXME
4161 * findvar.c (find_saved_register): Avoid problem in current frame.
4162 (read_relative_register): Ditto.
4163 (write_register): Convert byte order on the way out.
4165 * exec.c (file_command): Add.
4166 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4167 (xfer_memory): Common function between core_xfer_memory and
4169 (exec_xfer_memory): Use it.
4171 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4173 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4174 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4175 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4177 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4179 Merge Intel 960 port of gdb, continuing...
4181 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4182 symbol_file_command): Pass from_tty arg to hush 'em up.
4184 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4185 Add magic numbers for 960 COFF format.
4187 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4189 Merge Intel 960 port of gdb, from Intel "1.2" release.
4191 CHANGE_LOG entries from their port, which was based on
4194 Thu Sep 6 11:02:22 PDT 1990
4195 Remove temp file if download is interrupted.
4197 Wed Aug 1 09:08:33 PDT 1990
4198 Now uses binary protocol to talk to NINDY.
4199 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4200 Times out after 5 seconds when trying to talk to NINDY.
4202 Tue May 29 12:54:49 PDT 1990
4203 Added variable baud rate (-b switch).
4204 Source code reorganization.
4206 Thu Apr 26 11:09:55 PDT 1990
4207 More cleanup of batch mode; specifically, execute "-s", "-e", and
4208 "-se" switches as soon as they are encountered on the invocation line.
4210 Fri Apr 20 13:47:15 PDT 1990
4213 Thu Apr 19 09:54:28 PDT 1990
4214 Add 'reset' command.
4216 Wed Apr 18 09:48:07 PDT 1990
4217 After opening remote tty, wait for 1 second to go by without input
4218 from it before trying to talk to NINDY (fixes problems with the
4219 Heurikon HK80/V960E).
4221 Mon Apr 4 16:33:05 PDT 1990
4222 Some output was not being suppressed in 'batch' mode.
4224 Thu Mar 22 15:31:11 PST 1990
4225 Ask user if old symbol table should be deleted when new file is
4228 Allow user to run a program downloaded before gdb960 was brought up.
4230 Correct "exec-file" help message for i80960 context.
4232 Correct bug in calculating user space address: could occasionally
4233 corrupt user program.
4235 Make sure to zero low-order bits in rip's because of bug in 960CA
4236 A-step part: could cause operation faults when "next"ing across
4239 Correct bug that made it impossible to get source line numbers for
4240 code loaded at addresses higher than 0x7fffffff.
4242 Wed Jan 10 12:43:22 PST 1990
4243 Open remote tty for exclusive use.
4245 Fri Jan 5 12:14:42 PST 1990
4246 Correct disassembly (CA manual was right after all):
4247 opcode for sysctl is 0x659
4249 Mon Oct 23 12:03:04 PDT 1989
4250 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4252 Mon Oct 16 14:15:09 PDT 1989
4253 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4255 Mon Oct 2 15:56:31 PDT 1989
4257 Added 960CA disassembly support.
4259 To simplify maintenance:
4260 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4262 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4263 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4264 - made disassembly interface identical to that in gdmp960.
4268 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4270 * target.h: Allow targets to stack. Add target_has_memory,
4271 _registers, etc. Restructure memory access and "info files"
4272 to walk the target stack.
4273 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4274 target.c: Change tables to match target.h.
4275 * inflow.c (child_mourn_inferior): pop child_ops.
4276 (generic_mourn_inferior): Use new has_stack flag.

4279 * remote-eb.c: New memory regime, new info files.
4280 * remote-vx.c: New memory regime, new info files. Now use
4281 separate targets for VxWorks attachment to machine, and
4282 actually running a process under VxWorks, since one has
4283 stack & execution & regs and the other doesn't.
4284 * remote.c: New memory regime, new info files.
4285 * sparc-xdep.c (fetch_core-registers): New memory regime.
4286 * target.c: New routines and support for stacked targets,
4287 new memory regime, new info files regime.
4290 Generalize section handling for an arbitrary number of sections,
4291 including use of the new BFD (binary file) library.
4292 * gdbcore.h: Add struct section_table.
4293 * exec.c (build_section_table): Iterate all sections and
4294 record what gdb needs to know about them.

4301 * dbxread.c: Quick changes to make it compile with new BFD.
4302 * utils.c (error): Avoid using bfd_error in generic routines.
4304 * core.c (core_fetch_registers): Get from the ".regs" section of
4306 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4308 * inferior.h (attach_flag): Export.
4309 * infcmd.c (run_command): use new target_create_inferior.
4310 * infrun.c (child_create_inferior): Don't return result.
4311 * Makefile.dist (VERSION): 3.91.4.
4313 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4315 * breakpoint.c (bpstat_num): Handle breakpoints which have
4316 since been deleted, such as temporary breakpoints.
4317 infcmd.c (program_info): ditto.
4319 * core.c (core_file_command): Display the frame where the core
4324 * remote-vx.c (target_command): Merge in target command from
4325 targ-vx.c. A few other cleanups.
4327 * TODO, Projects: Lots more stuff to do...
4329 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4331 Massive changes to wall off the remote-debugging interface
4332 behind a function vector. The port to handle VxWorks targets
4333 is also part of this.
4335 All files: Replace references to renamed functions,
4336 remove references to remote_debugging, remove references to
4337 have_include_file, have_core_file in favor of target_has_stack,
4338 target_has_memory, etc.
4340 * Modularize the breakpoint interface.
4341 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4342 a breakpoint instruction.
4343 breakpoint.c: struct breakpoint's shadow_contents now sized as
4345 (insert_breakpoints): Vector to target to install breakpoints.
4346 (remove_breakpoints): Vector to target here too.
4347 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4348 sparc-tdep.c (single_step): Use new breakpoint interface for
4349 the single-step breakpoints.
4350 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4351 New file, contains routines to insert and remove breakpoints by
4352 reading out the old contents and later replacing them. This is
4353 how ptrace breakpoints work, and many remote systems as well.
4355 * tm-vxworks68.h: New config file, overrides a few things for
4356 Wind River's preferences.
4358 * target.h: New file, for transfer vector used to talk to the
4359 inferior (child, attached, core, exec, remote, etc). All accesses
4360 to the thing being debugged should come through these vectors.
4361 target.c: New file, routines to handle transfer vector.
4362 (various files): Add transfer vectors XXX_ops for the various
4363 targets and pseudo-targets (core files, etc) we support.
4365 * breakpoint.c (bpstat_stop_status): Further explorations of
4366 watchpoints and why things don't work all the time.
4367 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4369 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4370 the local gdbinit if it doesn't already have it.
4372 * core.c (core_ops): add and install.
4373 Allow core debugging without exec file.
4375 * dbxread.c (free_and_init_header_files): Merge two fns.
4376 (end_symtab): Free named symbol table when a new version comes in.
4377 (read_dbx_symtab): Relocate all kinds of symbols with base
4378 address. First step toward handling different text, data, bss
4380 (add_file_addr_command): Renamed add_file_command.
4381 (add_file_command): Vector to remote handler.
4382 Add "load" as an alias for "add-file" command.
4384 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4385 non-returning functions.
4387 * exec.c: Add exec_ops, and push it as a target when an exec
4390 * infcmd.c (run_command): Pass executable file name and arg list
4391 separately when starting an inferior. Permit "run" when no exec
4392 file is specified, for VxWorks.
4393 (detach_command): Move to child_detach in inftarg.c.
4395 * inftarg.c: New file. Unix-child-specific routines, and the
4396 child_ops structure.
4398 * inferior.h (registers): Export "registers" as the way for
4399 target dependent register handlers to find gdb's local copy of
4400 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4401 since it is now used by places that want wait_for_inferior to
4402 handle the grunge but want to see every trap from the inferior.
4404 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4405 Eliminate remote_debugging hooks in terminal handling.
4407 * infrun.c: Replace start_inferior with child_create_inferior.
4408 Move all the hair of Unix shells and ptrace idiosyncracies into
4409 child_create_inferior, so remote handlers don't have to deal.
4410 Remove running_in_shell. Rename stop_after_attach to
4411 stop_soon_quietly, and use it in a few other places where we want
4412 to just call wait_for_inferior and get control back on the first
4413 trap. trap_expected now never takes a value > 1.
4414 (init_wait_for_inferior): Initialize static vars when a new
4417 main.c (gdbinit): Add new hook for .gdbinit file name, let
4418 it be overridden by config files as GDBINIT_FILENAME.
4419 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4420 Both of these are used for VxWorks gdb.
4422 mcheck.c: rename include file "gmalloc.c" to avoid problems
4423 with system include file "malloc.c".
4425 param-no-tm.h: New include file, same as param.h but does not
4426 include the default "tm.h" file. This is used in files where
4427 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4429 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4431 remote-vx.c: New file, VxWorks remote debugging support. Uses
4432 RPC routines that are shared with the target system, in directory
4435 remote.c: Vectorize remote interface.
4437 source.c: Globalize source_path, and make an alias "l" for "list"
4438 since we now have the "load" command.
4440 sparc-xdep.c: Use new param-no-tm.h.
4442 symmisc.c (free_named_symtab): Add new function from Wind River.
4443 However, ifdef it out for now while we think about what it should
4446 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4448 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4449 non-Unix-children handle this with their own code in the target
4452 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4453 source and target lists. Add vx-share to default list of include
4454 directories. Add new files to src and target lists: mem-break,
4455 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4456 ${srcdir} versions of munch and createtags are used.
4458 * valops.c (find_function_addr): Split out of call_function.
4459 (call_function_by_hand): Rename call_function; this function
4460 calls functions in the target by laboriously patching the target
4461 word-by-word with the right stack, args, regs, etc.
4464 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4466 Handle AMD 29000 a bit better.
4468 * remote-eb.c (readchar): Mask received char log to make it readable.
4469 (remote_start): Pass arguments down to executing program.
4470 Make startaddr unsigned.
4471 infrun.c (start_inferior): Accept args, pass them to
4473 infcmd.c (run_command): Pass args down to start_inferior.
4475 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4476 the target object file format.
4477 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4479 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4480 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4482 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4484 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4485 * TODO: We did a few things, we have more to do though.

4488 * inflow.c (inferior_died): Clear deferred stores.
4490 * Debug problems with dummy frames and calls to the inferior.
4491 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4492 * sparc-tdep.c (do_restore_insn): Simplify.
4493 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4494 (sparc_push_dummy_frame): Simplify and fix what we push.
4495 (sparc_pop_frame): Slightly more hair here, deciding whether
4496 we are restoring a saved PC or returning to a return address in %i7.
4497 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4499 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4500 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4501 * obstack.h (chunkfun): ditto.
4502 * defs.h (xmalloc, xrealloc): ditto
4504 * utils.c (quit): Grab the terminal from the child if necessary.
4506 * inflow.c (term_status_command): Rename to term_info, change
4509 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4510 (is_delayed_branch): Speed up.
4511 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4512 Still missing some float ops, and needs testing.
4514 * Support for input and output radixes other than base 10
4515 * defs.h (input_radix, output_radix): Declare.
4516 * expread.y (yyparse, parse_number): Handle changes of input
4517 radix, and ambiguous names-or-numbers in radixes >10.
4518 * printcmd.c (print_scalar_formatted): Print formatted hex
4519 numbers in varying column widths.
4520 * valprint.c (val_print): Use output_format to print scalar ints.
4521 (set_input_radix, set_output_radix, set_radix): Create.
4522 (set_output_radix): Set output_format from output_radix.
4523 (_initialize_valprint): add `set radix' but leave the others off.
4525 * main.c (execute_command): Let stupid questions be turned off.
4526 (_initialize_main): Handle "set stupidity", etc.
4528 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4529 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4531 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4533 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4534 bfd stuff is still screwed up, but with some manual work, it
4537 * breakpoint.c (bpstat_do_actions): Start over if a command
4538 proceeds the inferior, since the inferior will have stopped and
4539 will need to have its new stop-actions taken care of.
4541 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4542 compiler fits, simplify it.
4544 * gdb.texinfo (directory command): Doc new dir command.
4545 source.c (directory_command): "dir" now puts things on the front
4546 of the path, moves dups up front, and handles multiple names
4547 on the command line, inserting each one in order. It also
4548 blows away cached line and full_filename info.
4550 * stack.c (backtrace_command): Skip "more stack frames follow"
4553 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4554 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4555 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4556 The only odd one was Gould NP1, which had defined vprintf to
4559 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4560 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4561 variable, inspect_it.
4562 valprint.c (print_string, val_print): Use the global inspect_it
4563 to indicate whether to print in Epoch style or normal style.
4565 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4567 * printcmd.c (call_command): add an alias for the "print" command
4568 which runs expressions and doesn't print the result if void.
4569 (print_command_1): implement it.
4571 * command.c: Remove #if 0'd code. Initialize all the fields
4572 in add_cmd (). Rename do_nothing_command to
4573 not_just_help_class_command, and make it externally visible.
4574 command.h: add user_commands to struct.
4575 * main.c (define_command): Don't overload c->function with a char
4576 string as well as a function pointer.
4578 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4579 calling convention of value_struct_elt () that got dropped in
4582 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4583 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4585 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4587 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4588 until a good time (e.g. when we are about to run the child),
4589 saving ptrace calls.
4590 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4591 * tm-sparc.h: define DO_DEFERRED_STORES.
4593 * sparc-xdep.c (store_inferior_registers): when storing float
4594 registers, don't store stack regs too. When storing the SP,
4595 however, DO store the stack regs too. This fixes a bug in which
4596 the dummy frame is not recognized when a call_function finishes,
4597 because its frame pointer (in the stack regs) was never
4599 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4600 even though we don't know how to read them from an inferior.
4601 valops.c (call_function): Comment about storing SP.
4603 * infrun.c (save_inferior_status): Save away the original bpstat
4604 chain so it can be restored later. Install the copied version for
4605 use by whoever saved the status. It will be blow away by
4606 restore_inferior_status, and the original chain restored. This is
4607 important for people who have pointers into the original.
4609 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4610 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4611 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4614 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4616 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4617 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4618 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4620 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4622 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4623 Store the baseclasses in a type struct starting from array element
4624 0 rather than from the unusual array element 1.
4626 dbxread.c: the above.
4627 (virtual_context): Add
4628 Read new debug information about which virtual function table
4629 a virtual function is from, and store it in fn_field.fcontext.
4631 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4632 TYPE_FN_FIELD_STATIC_P.
4634 symtab.c: the above.
4635 valops.c: the above. Handle pointer casts of object *'s.
4636 (search_struct_method): Add.
4637 (value_struct_elt): First arg is now a pointer to a value, and is
4640 valprint.c: the above.
4641 values.c (value_virtual_fn_field): Add type arg. Handle
4642 offsetting to the proper object when calling virtual fns.
4644 (baseclass_addr): Add valuep arg.
4646 * README: Document the current state of BFD config (missing).
4647 * TODO, ChangeLog, Makefile.dist: Roll version.
4648 * WHATS.NEW: Add summary of changes since 3.5.
4650 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4652 * dbxread.c (read_struct_type): Clear bit vectors whenever
4654 symtab.c (B_CLRALL): define.
4656 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4657 using == rather than =. Huh... This fixes the dreaded problem
4658 wherein builtin_type_int becomes TYPE_CODE_FLT.
4660 * core.c (info_files): Show the inferior pid.
4662 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4663 already knows how to look in the source directory.
4665 * Remove psymtab hair from many places. Remove duplicated code
4666 for searching symbol tables. Hide psymtabs from most places.
4667 Make it fast to get from a psymtab to its symtab.
4669 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4670 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4671 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4672 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4673 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4674 new symtab completely. New psymtabs get symtab pointer
4675 initialized to zero. Remove MI warning printf.
4676 symtab.h: Comments. Add psymtab to symtab pointer.
4677 (PSYMTAB_TO_SYMTAB): New macro.
4678 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4679 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4681 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4683 (print_frame_info): Avoid special-casing symbols that have not yet
4686 * source.c (open_source_file): Quick path if we have already
4687 located the source file by its full name.
4689 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4690 find_pc_psymtab. When a name is found in the misc function
4691 vector, search the symbol table for its mangled name, not the
4692 name that the user typed.
4694 * bfd.h: Fix missing comment terminators, make #endifs match.
4696 * valarith.c (value_less): Handle unsigned int comparisons.
4697 Add FIXME about pointer compares, which assume host and target
4698 pointers are the same.
4700 * command.c (do_nothing_command): lint
4701 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4702 fix comments on debug symbol format for visibility. Actually set
4703 visibility of symbols.
4704 main.c (echo_command): lint; use <readline/history.h>.
4705 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4706 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4707 pointing past end of allocated memory; saber complains.
4708 obstack.h: Declare the external functions that we use.
4709 valarith.h: use <string.h>
4710 solib.c (solib_add): lint.
4712 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4714 * main.c (initialize_main): Default info_verbose to off, now that
4715 symbol reading is fast.
4716 (quit_command): Avoid clobbering exec_bfd while quitting.
4718 * Initial BFD (binary file diddling library) merger:
4719 coffread.c: Change AOUTHDR to struct exe_hdr.
4721 core.c: initialize initialized data at compile time.
4722 (core_file_command): Move from coredep.c, convert to bfd.
4723 (xfer_core_file): Convert to bfd.
4724 exec.c (exec_file_command): use bfd routines.
4726 mips-tdep.c: Remove exec_file_command and friends.
4729 * coredep.c: (fetch_core_registers) Convert core_file_command to
4730 fetch_core_registers.
4731 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4733 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4734 (my_bfd_read): More bogosity, which I don't think we call.
4735 (program_name): Remove this atrocity asap!
4737 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4740 values.c: allocate_repeat_value was not clearing the
4741 optimized_out field.
4742 (value_static_field): minor stylistic fix (wrong macro was used).
4743 valops.c (value_struct_elt_for_address): didn't work for C++
4746 * signame.c (_initialize_signame): Initialize signal names once.
4748 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4749 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4750 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4752 * remote-eb.c: Support user-settable baud rates on the serial port.
4754 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4756 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4758 * tconfig/sun3os4: Remove warning about native assembler,
4759 since it also occurs in the xconfig file.
4761 * findvar.c (registers): Allocate some slop after `registers'
4762 to prevent stray accesses from trashing the next variable.
4764 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4765 on the sun-3, by changing the #ifdef from `sun3' (which is not
4766 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4767 vars, which happened to follow `registers' in the executable.
4769 * readline/history.c (history_search): Heed gcc-2's advice
4770 and parenthesize && inside ||).
4772 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4773 tm-29k.c: Insert FSF copyright headers.
4775 * remote-eb.c: Better comments.
4777 * Makefile.dist: Update to 3.91.6.
4778 * TODO: note PREPARE_TO_STORE problem.
4780 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4782 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4784 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4786 * infrun.c (wait_for_inferior, at end): Don't set up
4787 prev_* if the inferior no longer exists.
4789 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4790 CANNOT_EXECUTE_STACK.
4791 valops.c (call_function): Use it.
4793 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4795 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4796 infrun.c (wait_for_inferior, 2 places): Use it.
4798 * values.c (value_being_returned): Only use
4799 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4801 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4802 right thing for remote-eb.c.
4804 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4805 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4807 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4808 (FRAME_FIND_SAVED_REGS).
4810 * findvar.c ({fetch,store}_registers): Check for
4811 REMOTE_{FETCH_STORE}_REGISTER macro.
4813 * findvar.c (get_saved_register): Add argument lval and
4814 change meaning of argument addr.
4815 findvar.c: Change calls to get_saved_register to reflect
4816 new calling convention.
4817 valops.c (value_assign): Use get_saved_register instead of
4818 find_saved_register.
4820 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4822 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4823 an (uninitialized) pointer to one. Use "&" when passing it
4826 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4828 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4831 * coffread.c (symbol_file_command): Put semicolon after
4833 Put safe_to_init_tdesc_context in #if defined (TDESC).
4834 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4835 coffread.c: #include <sys/stat.h>.
4836 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4837 Add missing ')' in check for "lc%" and friends. Remove
4839 Declare read_one_sym() at top of file.
4840 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4841 MC68WRMAGIC can have the same value without causing a duplicate
4844 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4846 * Allow a Makefile to be built without building the
4847 tm and xm file links that screw up builds in subdirectories.
4848 This is done with `config.gdb none', then you can do things
4849 like `make gdb.tar.Z'.
4850 * tconfig/none: Config file for no target system
4851 * xconfig/none: Config file for no host system
4852 * config.gdb: If no TM or XM files are called out by the
4853 host or target file, don't make links for them.
4855 * cplus-dem.c: Add documentation.
4857 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4858 simple error, so the user's gdb doesn't crash due to some object
4859 file problem (e.g. somebody is rebuilding the file out from under
4862 * printcmd.c (print_address_symbolic): demangle the symbol.
4864 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4865 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4866 (alldeps.mak): sort and uniq all results from this; duplicates
4867 hose gdb.tar.Z link building. Remove RCS files from
4868 tconfig and xconfig. Add config files for sun386. Add
4869 a few odd files to OTHERS and HFILES.
4871 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4873 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4874 Roll version number to 3.91.5. Make lint work in bindir.
4876 * README: Document cross-debugging and new file structure.
4878 * blockframe.c: Lint. Include "value.h" to declare read_register.
4879 (find_pc_partial_function): remove duplicate line.
4881 * command.h: Lint. Declare error_no_arg and dont_repeat.
4883 * tm-news.h: Remove inadvertently duplicated stuff.
4885 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4886 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4888 * config.gdb: Allow `config.gdb host target' form. Clean
4889 up previous change that printed bogus messages when you just said
4892 * core.c: #include "command.h" for lint.
4895 * main.c: Remove some casts of enums. Lint.
4902 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4904 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4905 read it from memory. This will allow us to save ptrace calls
4906 eventually. Changed caller single_step too.
4908 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4909 that we aren't going to use, saving many ptrace calls, especially
4910 when watchpointing or single stepping. Use some #define's for
4912 (store_inferior_registers): Ditto.
4913 (core_file_command): Use some #define's for constants.
4915 * tm-sparc.h: Add #define's for some register numbers, so we
4916 can eliminate the use of random constants in sparc-xdep.c.
4918 * stack.c (frame_command, print_frame_info, up_command,
4919 down_command) Remove frame_changed, since it
4920 causes a bug and doesn't seem to do anything useful. In some
4921 places it was used as a flag, in others as a stack level (?).
4923 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4924 default is to use the portable (vprintf) version rather than the
4926 * xm-news.h (MISSING_VPRINTF): Add.
4928 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4930 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4932 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4933 about linking debugged programs -Bstatic in the sun?os4 config
4934 files in tconfig and xconfig subdirectories.
4936 * main.c (main): Remove unreached exit(0) now that we exit
4939 * Create TODO file for online bug list. There are too many
4940 "little" bugs to keep track of on paper.
4942 * Change Projects file to refer to bug-gdb@cygnus.com
4943 rather than kingdon@ai.
4945 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4947 * Makefile.dist (VERSION): 3.91.4 now.
4949 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4950 (condense_misc_bunches): Add sanity check that misc_count is
4951 the same as the number of symbols in the bunch.
4953 * coffread.c: rename init_misc_bunches. Pass an argument
4954 to condense_misc_bunches (a zero).
4956 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4957 every time we are called; don't rely on our caller to do it.
4958 (add_file): Remove call to init_misc_bunches.
4960 * mipsread.c: Only warn, don't error, if unknown symbol types.
4961 This keeps an old gdb from falling on its face if it sees newly
4962 extended symbol info. Rename init_misc_bunches.
4964 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4966 * Merge in changes from Per Bothner for DECstations and other
4967 MIPS stuff. The rest is Bothner speaking:
4969 The next message is a merger of Alessando Forin's mips port with
4970 mine. I've tried to use my good if biased judgment to get
4971 the best of both. It *does* need testing.
4973 Some of the changes are general, *not* mips-specific.
4976 Didn't believe in little-endian bit order.
4977 There are still inconsistencies about whether flags
4978 like BITS_BIG_ENDIAN are integer (#if ...) or
4979 boolean (#ifdef ...). I tried to paper over them.
4981 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4982 Moved some misc_function code that was common to
4983 {dbx,coff,mips}read.c to symtab.c.
4984 In the process, I think I cleaned things up a bit.
4985 At the same time, moved obsavestring and obconcat to symtab.c.
4988 Removed obsolete condense_addl_misc_bunches (use
4989 condense_misc_bunches(1) instead).
4992 Needed to include <sys/dir>, at least on DECstations.
4994 valops.c, mips-tdep.c, tm-mips.h:
4995 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4996 conventions (when STACK_ALIGN is insufficient).
4997 Needed on mips, where doubles need 8-byte alignment,
4998 but ints only need 4.
5001 Removed cruft that was not being used.
5002 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
5005 Print $ before register-names (I think that makes things a little
5007 Never print two instructions, even if one delays.
5008 Removed hex-disassemble set_cmd. (This is not mips-specific,
5009 so I think the argument is whether it is generally worthwhile or not.
5010 I'm inclined to think not, given how easy it is to
5011 convert between radixes in gdb.)
5014 This is basically Alessando's code.
5015 It doesn't use obstacks; I changed it to use obstacks
5016 in a few minor places where using malloc causes a
5017 memory leak. (Probably, more places could/should be changed.)
5018 I added record_misc_function where it was missing.
5019 In symbol_file_command and add_file_command, I tried
5020 to make the code consistent with more recent versions.
5021 Minor sylistic changes in parse_procedure.
5022 Make a .gdbinfo. psuedo-symbol point back to the real
5023 procedure symbol (using the isym field).
5026 This is basically from my port, but with a lot of details
5027 and a number of routines merged in from Alessando's version.
5028 I basically used my code "raw" backtrace (use heuristics
5029 from the actual code, rather than symbol table info) - though
5030 the idea is Alessandro's. I feel my code is a little cleaner
5031 here, particularly in being a little more flexible, such as being
5032 able to handle gcc-produced code (which it now can).
5033 It also doesn't do frame caching (which is not useful
5034 more recent gdb versions).
5035 I also used my code for push_/pop_dummy, more or less.
5036 I tried to incorporate AF's code for testing sigtramp
5037 while backtracing; I probably got it wrong.
5038 Added mips_print_register, which tries to scrunch as much
5039 information as possible on a screen...
5040 Removed the skip-prologue set_cmd. As with hex-disassemble (see
5041 under mips-pinsn.c), I don't see anything mips-specific here,
5042 and I don't see it being all that useful anyway.
5045 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
5046 Use more register names (rather than hard-cases numbers).
5048 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
5050 * Hack up 3.90.11 changes:
5052 * Makefile.dist (depend): parameterize $(GCC).
5053 Add solib.c and solib.o.
5054 (readline): Fix vpath for both absolute or relative SRCDIR.
5056 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
5057 Also, let the part I didn't understand at least compile so
5058 I can test the rest. FIXME.
5060 * dbxread.c: Fix thinko using strcmp.
5061 (init_psymbol_list): declare static.
5062 (partial_symbol_file_open): Comment cleanups better, avoid
5063 cleaning up the string table since the caller will do that.
5064 Move the stat for mod time into symbol_file_command, temporarily.
5065 (There should be a mod time for each symbol file, eventually,
5066 to control its rereading. FIXME.)
5068 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
5069 SunOS, which gives error for shared libs otherwise. (From
5070 Schaefer, probably FIXME needs work for portability.)
5072 * solib.c: Move #include "param.h" to work.
5073 Lowercase all the Uppercase Letters In the Messages.
5074 (find_solib): Clean up inferior_so_name for debug printouts.
5075 Allow no argument, to mean all shared libraries.
5077 * symmisc.c: include param.h to get CLEAR_SOLIB.
5079 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
5081 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
5082 to 3.90.11. ChangeLog entries below are from this.
5084 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5088 * Makefile.dist (HFILES): Add tm-sunos.h.
5090 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5094 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
5096 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
5098 * sparc-opcode.h Added single-operand version of rett.
5100 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5102 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
5103 Put parens around gcc_p in expansion.
5105 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
5107 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
5109 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5111 * Changes for Sun shared libraries:
5112 blockframe.c (find_pc_partial_function): If a non-text symbol
5113 is found, set *address = pc - FUNCTION_START_OFFSET.
5114 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5115 Disable breakpoints instead of giving an error.
5116 source.c (select_source_symtab): Initialize cs_pst.
5117 symmisc.c: Call CLEAR_SOLIB if defined.
5118 symtab.h: Make text{low,high} CORE_ADDR not int.
5119 (psymtab): New field addr.
5121 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5122 (record_misc_function): Give correct type for N_DATA symbols.
5123 (condense_misc_bunches): do "misc_function_count = j" regardless
5125 Take code which is shared between symbol_file_command and
5126 add_file_command and put it into partial_symbol_file_{open,read}.
5127 Split add_file_command into add_file_command and add_file.
5128 Make psymtab_to_symtab read in the string table if the file
5130 Two new parameters to read_dbx_symtab and start_psymtab.
5131 tm-sunos.h: New file.
5133 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5135 * infcmd.c: Change cont_command to continue_command and "cont"
5138 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5140 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5142 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5144 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5145 size 1,2,4,8 rather than size < 8.
5147 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5148 as necessary, not just once.
5150 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5152 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5154 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5156 * tm-news.h: Add CALL_DUMMY_*.
5158 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5160 * config.gdb: In list_host, list_target, use ${i}, not $i.
5162 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5164 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5166 * sparc-opcode.h: Change all store floating-point state register
5167 instructions to have the right match & lose fields.
5169 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5171 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5173 config.gdb: If srcdir != ., create readline directory and
5174 copy a makefile into it.
5176 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5177 consistency with POSIX.
5179 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5180 when we exit its exp_valid_block.
5182 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5184 * Makefile.dist: Bump version to 3.91.3.
5186 * Clean up handling of breakpoint commands (somewhat).
5187 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5189 inferior.h: Add breakpoint_proceeded to inferior status struct
5190 and globals; save it and restore it.
5191 (clear_breakpoint_commands): Cleanup, remove old #define.
5193 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5194 (save_inferior_status, restore_inferior_status): handle it also.
5195 (proceed): Remove earlier code that set breakpoint_proceeded.
5196 It is now set only in clear_proceed_status.
5197 (clear_proceed_status): Cleanup, use bpstat_clear rather
5198 than clear_breakpoint_commands. No callers need the stop_bpstat
5199 between clear_proceed_status and proceed.
5201 infcmd.c: Add breakpoint_proceeded definition and comment.
5202 (cont_command, jump_command, signal_command): Move call to
5203 clear_proceed_status right next to call to proceed.
5205 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5206 caller's argument while running down the chain of breakpoints.
5207 Use new variable "breakpoint_proceeded" to determine when
5208 a command that it executes moves the inferior past the
5210 (bpstat_clear): Handle NULL argument.
5211 (bpstat_clear_actions): Avoid useless call to
5212 breakpoint_auto_delete.
5213 (delete_breakpoint): Clean up bpstat's that are pointing to
5214 the deleted breakpoint from the stop_bpstat chain.
5215 (breakpoint_auto_delete): Simplify.
5217 * Clean up handling of EOF, error on stdin, etc. This was
5218 prompted by a network problem that caused gdb to go into an
5219 infinite loop filling up its malloc'd memory.
5221 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5222 not clear_breakpoints_commands, which is now gone.
5223 (main): If command_loop returns (e.g. from EOF on stdin), do
5224 a quit_command (looping back to command_loop if quit_command
5225 doesn't really quit).
5226 (command_loop): check result from command_line_input and
5227 exit if it returns NULL, rather than passing the NULL to
5229 (gdb_readline): Free malloc'd result space before returning
5232 * utils.c (query): Handle C-d to mean "yes", just as if the
5233 input was not a terminal. Also avoid infinite loop if EOF
5234 occurs in mid-input-line before newline. This allows
5235 query to be used at EOF on stdin with reasonable results.
5237 * infrun.c (proceed): Set breakpoint_proceeded.
5239 * values.c (value_as_long): Avoid infinite recursion for enums.
5240 (_initialize_values): Fix typo in help msg (kingdon).
5242 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5243 RL_LIB for linking. This allows -lreadline for linking
5244 and nothing for dependencies, once readline is a real library.
5246 * config.gdb: Jim Kingdon: give useful error message if the
5247 host or target type is not recognized.
5249 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5250 it just defines it. Dumb, but deal with it.
5252 * Jim Kingdon suggests:
5253 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5255 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5257 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5259 * Clean up Bothner's changes.
5261 * blockframe.c (clear_pc_function_cache): New function.
5262 * blockframe.c: remake cache_pc_function_* static.
5263 * dbxread.c (symbol_file_command): remove references to
5264 cache_pc_function_* variables.
5265 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5266 * printcmd.c: Avoid kludging a global variable (addressprint)
5267 to avoid printing the address of a string twice. Instead,
5268 pass the format letter 's' down low enough that it can be seen
5269 to avoid this problem.
5270 (print_formatted): Pass format arg to value_print.
5271 (restore_addressprint): Remove function.
5272 (do_examine): Avoid hacking addressprint, cleanups and such.
5273 (print_frame_args): Add a comment to a Bothner change.
5274 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5275 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5276 to wipe out the values cached in blockframe.c.
5277 * symtab.c (find_method): Add comment saying how big you must
5278 allocate to be "big enough". Per being terse again.
5279 * valprint.c (val_print): Handle format letter "s" to print
5280 strings without addresses. Add comment to vtbl printing code
5281 which casts with wild abandon. Rearrange reference-printing
5283 @0xaddr: value (print w/addressprint)
5284 value (print w/~addressprint)
5285 @0xaddr (parameter lists w/addressprint)
5286 or nothing (parameter lists w/o addressprint)
5288 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5290 * Merge more changes from Per Bothner:
5292 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5293 annoying) that I tried to improve it. Here are my suggestions.
5295 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5298 Do automatic de-reference when taking the address of a reference.
5300 Don't deref_ref when printing parameter lists.
5302 More attempts at treating refernences properly.
5304 In val_print, if deref_ref==0, don't print dangling " = ".
5306 Add COERCE_REF macro, which de-references an REF.
5308 * Merge changes from Per Bothner:
5310 * Fixed (Sony news)-specific configuration problems.
5311 * Fixed other problems with using vanilla pcc and libc (enum problems;
5312 assumption that vsprintf exists).
5313 * Some major speed-ups (finc_pc_partial_function now caches a match;
5314 parsing avoids duplicate symbol_lookup calls).
5315 * Changed handling of baseclasses (no longer use baseclasses field
5316 of struct type, use the first n_baseclasses fields instead).
5317 * Various minor changes/fixes, most C++-related.
5320 Cache the most previous match from find_pc_partial_function.
5321 (Save both low and high ends of matching function's pc range.)
5322 This speeds up the loop of infrun.c:wait_for_inferior quite
5323 a bit, and makes step/next commands much zippier.
5325 Added an enum->int cast (otherwise, some compilers barf).
5327 No longer set baseclass offset to 0, since multiple
5328 inheritance now mostly works.
5329 Added a number of casts, to shut up compiler warnings
5330 (after stabs where made enums, not ints).
5331 When discarding a symbol table (in symbol_file_command),
5332 must clear the cache introduced in blockframe.c.
5333 Don't convert $vtbl_ptr_type to vtbl any more.
5334 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5335 Mask off sign bit emitted by g++ for virtual table offset.
5336 Set voffset to -1 (not 1) for static member functions.
5338 Changed parsing/lexing of names to avoid doing symbol lookup twice
5339 (once when lexing to determine symbol class, once for real).
5340 Now only call symbol_lookup once. Fields of 'this' win especially big.
5342 Subpress printing addr twice in the case of 'x/s addr'.
5344 lookup_basetype_type is no longer used.
5345 Add find_methods as recursive helper function to decode_line_1.
5346 This allows multiple inheritance to work.
5347 Also, once one or more matches has been found, do not look in
5348 base-classes. (Baseclass methods would be overridden, anyway.)
5350 Removed baseclasses array in struct type.
5351 Instead of using baseclasses[i], use fields[i-1].
5352 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5353 Changed sign convention of voffset (previous was inconsistent).
5355 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5357 Used to assume existence of vsprintf. Re-written to not need it
5358 if HAVE_VPRINTF is undefined.
5360 typecmp was too pessimistic. Made it less so.
5362 Don't print space after address.
5363 If vtable points to a misc symbol (with 0 offset), print it,
5364 since that indicates the actual class of the object.
5365 Changed ype_print_derivation_info to use new inheritance
5366 scheme (without baseclasses vector).
5368 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5369 Also, changes needed because TYPE_BASECLASSES were removed.
5371 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5373 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5376 If there is no path set, and the symbols don't indicate what directory
5377 a file was compiled in, look in the current directory. But either
5378 a path or a known compilation directory will prevent this.
5381 Three independent bug fixes:
5382 * Remove the #if 0 block that breaks some stuff.
5383 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5384 adapt gdb to either SunOS 4.0.* or 4.1.
5385 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5388 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5391 (type_print) Demangle the name being printed.
5392 (type_print_base) Handle botched demangling without coredump (tiemann).
5395 (check_stub_method): Document routine.
5396 (tiemann) fix bug for no-arg functions
5397 Avoid clobbering beyond end of malloc'd storage.
5398 Terminate the argument list properly.
5400 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5402 * Changes merged by John Gilmore:
5405 In breakpoint_1, use new print_address_symbolic instead
5406 of find_pc_partial_function. (This forces use of assembler-level
5407 addresses, and avoids misleading non-mangled source-level names.)
5409 Generalize ansi argument such that -1 means skip arglist totally.
5410 Removed global variable print_ansi_qualifiers (which made
5411 code non-reentrant), in favor of extra explicit arguments
5412 to internal routines.
5414 Add new helper function print_address_symbolic.
5415 Use find_pc_misc_function instead of find_pc_partial_function
5416 (since we want assembler-level symbols here).
5418 Print unknown function as just "f (...)", not "f (...) (...)".
5419 Use new fputs_demangled explicitly.
5421 Fixed a typing violation (problem: value.h cannot be imported
5422 without renaming many variable in this file).
5423 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5424 decode_line_1: Moved forward some never-reached code.
5425 Made decode_line_2 skip function prologues correctly.
5427 fputs_filtered should not demangle by default.
5428 Add new fputs_demangled to demangle on demand..
5430 Change value_struct_elt to use value_primitive_field (using recursive
5431 utility function search_struct_field). This allows foo.bar to work
5432 for multiple inheritance (so far only for data fields).
5433 Change check_field in the same way (recursive helper function
5434 to support multiple inheritance).
5435 (Note: there are more of these problems that I haven't fixed.
5436 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5437 value_of_this: 'this' symbol name is now just "this", note "$this".
5439 Don't print static members.
5440 Avoid printing "members of <type>" if there are none.
5441 Simplified type_print_derivation_info by merging duplicate code.
5442 Remove useless blank lines in type_print_base (ptype command).
5444 Added declaration of new routine value_primitive_field.
5446 Added value_primitive_field which is generalized version of
5447 value_field that can handle multiple inheritance (non-zero offsets etc).
5448 Re-implemented value_field to call value_primitive_field.
5450 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5452 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5453 delete the whole environment. Karl Berry reported the bug.
5454 * source.c - fix openp to avoid //'s in filenames, which
5455 trigger an Emacs bug causing it to not be able to find files
5456 when running gdb in a window.
5457 * dbxread.c - zap the #if 0 that botches the add-file code.
5458 It seems to work a lot better without all the code commented out.
5460 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5462 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5465 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5467 * Makefile - added a ${CFLAGS} to a couple of entries,
5468 added remote-sa.sparc.c
5469 * added remote.sa-sparc.c, a modification of remote.c
5470 which conducts a dialog directly with the SparcStation prom.
