1 Fri Sep 20 15:46:00 1991 Roland H. Pesch (pesch at cygnus.com)
3 * doc/Makefile: generate aux version-no file doc/gdbVN.m4
4 from main Makefile.in version definition
5 doc/gdb.texinfo: use version recorded in doc/gdbVN.m4 for current
7 Makefile.in (setup-to-dist): generate doc/gdbVN.m4
9 * doc/gdb.texinfo: merge new language-switching and lang-specific
12 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
14 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
15 compilers (which may lack stddef.h).
17 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
19 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
20 N_WARNING are the same except for the N_EXT bit, so just use their
21 values alone, rather than OR-ing them with N_EXT.
23 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
25 * mipsread.c (parse_lines): Deal with negative extended line
28 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
29 global symbol conflicts.
31 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
33 * .gdbinit: Move 'set complaints' to top, so it runs even in
34 case we aren't debugging GDB.
35 * language.c (_initialize_language): Fix type check and range
36 check documentation strings.
37 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
38 language.c can use it. (Though language.c should really not be
39 handling warnings/errors the way it does, FIXME.)
40 * symtab.c (lookup_primitive_type): const lint.
42 Bugfix from Peter Schauer:
43 * source.c (lines_to_list): Make signed, to avoid comparison
44 going unsigned and complaining that -3 is too high for 21 lines.
45 * stack.c (lines_to_list): Ditto.
47 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
49 * Makefile.in (HFILES): Add minimon.h.
50 (VERSION): Roll version number to 4.0.95.
51 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
52 New rules for building distributions. Normal distribution
53 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
54 one level up from here; it calls make-proto-gdb.dir to build a
55 directory `proto-gdb' which is an image of the release. The old
56 `gdb.tar.Z' rule still works too.
57 * config.sub, configure: Roll in latest from ..
59 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
61 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
62 new-target, and new-config chapters; fix minor typos; come closer
63 to usual GNU markup conventions for @file @samp @code @var.
65 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
67 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
68 * mipsread.c (parse_partial_symbols): Enter the name of all
69 structs/unions... into the psymtab so we can access them if the
70 symtab is not read in.
71 * mips-tdep.c: Remove some unneded (?) #includes.
72 * xconfig/dec3100: Add HAVE_STRSTR.
74 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
76 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
77 * c-exp.y, m2-exp.y: Lint.
78 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
79 * valprint.c (val_print_fields): Check for stub type.
80 * mipsread.c (_initialize_mipsread): Avoid using
81 builtin_type_void at initialize time.
82 (mipscoff_symfile_read): use it now.
84 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
86 Merge multiple-language support, and partial Modula-2 support,
87 from Andrew Beers <beers@cs.buffalo.edu>.
89 * i387-tdep.c: New file, consolidates most 80387 support,
90 and eliminates host dependency on double<->extended conversions.
91 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

104 (read_dbx_symtab, case N_DEFD): Ignore.
105 (read_enum_type): Recognize FALSE/TRUE enum as Modula-2 BOOLEAN.
106 (read_range_type): Rename MAX_OF_TYPE to MAX_OF_C_TYPE, etc.

108 * coffread.c (end_symtab): Use allocate_symtab.
109 (process_coff_symbol): #if 0'd for functions and params as above.
110 (read_enum_type): Recognize Modula-2 BOOLEAN.
111 * symtab.c (add_param_to_type): #if 0'd function to add a
112 parameter type to a function type's field list.

184 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
186 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
187 entries are enclosed herein:
189 Mon Jun 3 17:05:45 EDT 1991
191 m2-exp.y Created. Tested outside of GDB for a few days. Proper
192 operators were added, C specific operators and tokens
193 removed. yylex() revamped to some extent. Still things
194 missing from the grammar, such as sets.
195 Tested for two weeks in GDB v3.5.
197 Tue Jun 11 17:23:48 EDT 1991
199 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
200 so they are built-in. Sort of a hack.
202 Fri Jun 14 12:53:51 EDT 1991
204 m2-exp.y Added range checking for numeric constants. Any numeric
205 constant is assumed to be of builtin type INTEGER unless:
206 (1) it is octal or hexadecimal, in which case it is a
207 CARDINAL; (2) it is too big to fit into an INTEGER, in
208 which case it is a CARDINAL.
209 eval.c Added simple range checking for +, -, and * on integers.
210 Doesn't work very well for *, since 6 * 1,000,000,000 =
211 1,705,032,704, which fails the simple test of result >=
212 first_operand, no matter in what order the operands are.
214 Tue Jun 18 14:11:30 EDT 1991
216 Broke the parser into parts, one containing the C grammar and the other
217 containing code to be shared by all of the grammars.
219 The following files no longer exist:
224 The following files were added:
226 c-exp.y (The C grammar)
227 m2-exp.y (The Modula-2 grammar)
228 parser-code.c (Code that is shared by the above grammar)
232 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
233 now necessary to use the Bison compiler compiler, since it
234 will generate function/variable prefixes other than yy.
236 Tue Jun 18 16:47:49 EDT 1991
238 symtab.[ch] Added the external variable working_lang, than holds the
239 value of the current working language.
240 Added the ennumerated type language_mode, with the values
241 language_auto and language_manual, the former meaning that
242 GDB sets working_lang as needed, and the latter meaning
243 that the value of working_lang is totally under user
245 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
246 REAL, BOOLEAN and CHAR. Also added the type codes
247 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
248 utils.c Added set_language_command and show_language_command to
249 implement the GDB support commands "set language" and
251 expression.h A number of identifiers were added to the type exp_opcode
252 to facilitate Modula-2 builtin functions, integer
253 division, and array indexing.
255 Wed Jun 19 13:25:58 EDT 1991
257 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
258 if the language specified by working_lang requires the use
259 of strict typing of expressions. Eventually, even this
260 will be able to be changed by the user.
261 Added the macro RANGE_CHECK, which evaluates to non-zero
262 if the language specified by working_lang requires the
263 checking of a value against the domain of its type.
264 Eventually, even this will be able to be changed by the
266 language.[ch] Predicates involving types (simple_type, ordered_type,
267 same_type, integral_type, numeric_type, character_type,
268 boolean_type, float_type) are added. These predicates are
269 based on the current value of working_lang, and are handy
272 Wed Jun 19 15:39:34 EDT 1991
274 eval.c Added the function type_array_rank which computes the rank
276 valarith.c Added the funtion value_bool, which when given a integer
277 value.h value (ie. struct value *) as an argument, it returns a
278 boolean value (ie. struct value *) true if that integer
279 is non-zero, and a boolean value false otherwise.
280 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
281 will print out properly.
283 Wed Jun 19 16:36:34 EDT 1991
285 valops.c Added the function value_capitalize, which returns it
286 value.h argument capitalized if its argument is a lowercase
287 letter, or the argument unchanged if its argument is not a
289 valarith.c Added the function range_check_p, which returns non-zero
290 value.h if its value argument is between the integral bounds upper
292 Added the function range_check_enum_p, which makes sure
293 that its value argument is a valid member of the domain of
295 Added the function range_check_range_p, which makes sure
296 its value argument lies between the upper and lower bounds
297 of its type argument, which must be a ranged type.
298 Added the function check_array_index, which range and type
299 checks an index of an array.
300 Added the function value_multi_subscript, which computes
301 array[idx1,idx2...idxN], given a value array and an array
302 of values representing indicies.
303 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
304 unpack_long to work with TYPE_CODE_BOOL and
307 Wed Jun 19 18:04:08 EDT 1991
309 symtab.c Stored pervasive types in a structure and make
310 lookup_pervasive_type() a lookup function that was based
311 on working_lang. If lookup_pervasive_type() returned
312 non-zero, then that value was returned (a fix, since
313 before it simply wouldn't return the pervasive type.)
314 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
315 non-zero if the language specified by working_lang means
316 "conversion" when it says "cast".
317 valops.c Added the function value_real_cast(), which performs a
318 value.h *cast*, not a *conversion*, which is what value_cast()
319 does when it can. In particular,
320 value_cast(<float_type>,4) = 4.0, while
321 value_real_cast(<float_type>,4) = some mess.
322 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
323 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
324 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
325 and MIN on integral types. *NOTE*: These are currently
326 hardcoded to work only if there are 8 bits per storage
328 eval.c Made logical functions call value_bool to return a
329 properly typed boolean value, based on working_lang.
331 Thu Jun 20 11:55:27 EDT 1991
333 valprint.c Types now print out in a Modula-2 fashion. This works for
334 the cases when the type is printed out step-by-step, that
335 is, it doesn't work when the name of a structured type
336 (which includes the keyword "struct", etc.) is simply
338 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
339 since type specifications in C and Modula-2 are very
340 different. The C printing of a type is very recursive,
341 whereas in Modula-2 it is generally very simple. C has
342 type prefixes and suffixes, which have no real analogue in
343 Modula-2. Maybe type_print() should call a language
344 specific type printer. This is also advantageous if we
345 compile GDB to exclude some of the languages. We'll just
346 leave those functions out.
348 Thu Jun 20 16:57:10 EDT 1991
350 dbxread.c When reading the complete symbol table in (via
351 psymtab_to_symtab()), the number and types of function
352 arguments are added to a function type. define_symbol()
353 calls add_param_to_type() to accomplish this.
354 Assumption: when we come across a function definition
355 (N_FUN symbol with an 'f' or 'F' in the name), its
356 arguments will appear before another function definition.
357 When a function is found, a pointer to its type is placed
358 in the global in_function_type. Changes that
359 add_param_to_type() makes are to this global.
360 valprint.c The type of a function now includes (for Modula-2) the
361 types of its parameters.
362 eval.c Type checking and a check for the proper number of
363 arguments is now done for function calls. Not sure of the
364 impact this has on C++ member function yet.
366 Thu Jun 20 19:58:48 EDT 1991
368 valprint.c Rewrote the type printer. Broke it into two language
369 specific parts, adding the functions type_print_m2() and
371 An unfortunate consequence is this: if you debugging a C
372 program in Modula-2 mode (why?), info types does not work
373 well with regular expressions, since the types are printed
374 out in Modula-2 terminology, but stored in C terminology.
375 language.[ch] Added the functions new_type_last(), type_keyword(), and
376 type_sep() to aid in the printing of typedefs.
377 symtab.c Made the printing of typedefs as language independent as
378 possible through calls to new_type_last(), type_keyword(),
381 Fri Jun 21 11:50:26 EDT 1991
383 dbxread.c Check all incoming ennumerated types. If it looks like
384 Modula-2's BOOLEAN type, then change the type_code of the
385 type to TYPE_CODE_BOOL so we can process it as a boolean
387 valprint.c Replaced some of the 0x%x with calls to sprintf and
388 hexformat() in val_print().
389 language.[ch] Added the function hex_to_string(), which converts its
390 integral argument to a hexadecimal number (format is
391 language based) and returns the result as a string.
393 Mon Jun 24 12:25:07 EDT 1991
395 valprint.c Some functions call type_print_1() directly, instead of
396 value.h using type_print(), so they can specify where (column) to
397 print things. Since type_print() takes care of language
398 dependence, that needs to be called first. Added a
399 parameter depth to type_print() (so it is now like
400 type_print_1). Changed type_print to type_print_at, and
401 made type_print a macro that passes a depth argument of
403 symmisc.c Changed all calls to type_print_1 to calls to
405 Makefile.dist Made it possible to build GDB for a specific set of
406 depend languages. Do this by passing a definition for the macro
407 LANGS to make. LANGS should be a string containing a
408 space-separated list of language names (ie. LANGS="c m2").
409 The default is to build all languages. Note that grammar
410 files must follow the naming convention of <lang>-exp.y.
411 gdb.lang This holds the current value of the LANGS macro. It is
412 examined every time make is called, and is updated if
414 eval.c Added #ifdef _LANG_<lang> to these files.
415 expread.c Still need to add them to dbxread.c and coffread.c.
423 Mon Jun 24 16:33:11 EDT 1991
425 language.[ch] Added the functions hexformat_pre() and
426 hex_to_string_pre(), which take a prefix argument to
427 include in the format string. Thus, hexformat_pre("08") will
428 return "0x08x" (if the working language is language_c).
429 Made hexformat() and hex_to_string() calls to the above
430 with "" as the prefix argument.
432 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
433 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
434 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
435 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
436 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
437 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
438 valprint.c, vax-pinsn.c
440 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
441 calls to hexformat() and hex_to_string(). Format strings without
442 the leading "0x" were ignored.
444 depend Updated to take the above into account.
447 Tue Jun 25 15:27:18 EDT 1991
449 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
450 and type_check_t to keep track of the current state of
451 range and type checking.
452 main.c Added the variables range_mode, range_check, type_mode,
453 and type_check to record the current state of range and
454 type checking. Added initialization code to main().
455 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
459 Tue Jun 25 17:57:08 EDT 1991
461 dbxread.c process_one_symbol() updates the variable (enum language)
462 source_lang based on the extension of the filename
463 contained in the N_SO sybmol that started this symtab.
464 When end_symtab() is called, the value of source_lang is
465 put into the language field.
466 stack.c select_frame() sets working_lang (and possibly type_check
467 and range_check) to the language field of the symtab
468 associated with the frame that is selected if working_mode
469 is language_auto. If working_mode is language_manual, a
470 warning is printed and working_lang is not set.
471 language.c Added the function set_type_range(), which sets the value of
472 type_check and range_check (if their modes call for
473 automatic setting) based on the current value of
474 working_lang. A non-zero argument will cause the current
475 settings to be output.
478 Wed Jun 26 14:51:40 EDT 1991
480 eval.c Added range checks on assignment.
481 m2-exp.y Added the grammar for sets to the language. Currently,
482 these do not do anything except print an error message.
484 Wed Jun 26 17:01:04 EDT 1991
486 m2-exp.y Added the ability for parse_number() to parse negative
487 numbers. A global flag is set upon encountering a unary
488 minus. This was done to make, for example, 1 parse as a
489 CARDINAL, and not as an integer, per Wirth's examples in
490 Programming in Modula-2 ed.4.
491 valprint.c Added support for "set radix 2" by then setting
492 output_format to 't'.
493 eval.c Implemented range checking on subrange types. Added calls
494 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
495 Implemented MIN and MAX for ennumerated types. The
496 minimum value of an ennumerated type is defined by Wirth
497 as the first identifier, and the maximum as the last.
498 m2-exp.y Made octal numbers ending with "B" be characters and those
499 ending with "C" be numbers, per Wirth's book. (p. 34)
501 Thu Jun 27 14:11:52 EDT 1991
503 stack.c select_frame() now only sets working_lang, it does not
504 notify the user. If working_mode is language_manual, then
505 a warning is issued once.
506 main.c At the end of each call to execute_command(), working_lang
507 is checked against the local static (enum language)
508 current. If they differ and working_mode is
509 language_auto, the new settings of language, type and
510 range checking are printed out.
511 stack.c Modified frame_info() to include the language of the
512 current frame in the output of "info frame".
513 language.[ch] Added the function language_str() which returns the name
514 of the current language.
516 Fri Jun 28 15:33:14 EDT 1991
518 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
519 the language. INCL and DECL currently cause an error,
520 since sets are not implemented yet. INC and DEC are
521 implemented as PREINCREMENT/PREDECREMENT with one
522 argument, and as ASSIGN_MODIFY with two arguments.
523 eval.c Added type checking to the above cases.
524 value.h Added not_lval_constant to the lval_type ennumerated type.
525 not_lval_constant means that the value is a constant
526 value; that is 3 or 'a' or TRUE, not as in a constant
527 identifier. This is used to help coerce numbers such as 3
528 to either signed or unsigned numbers.
529 valops.c Added the function value_coerce_constants() which coerces
530 constant integers as following: if one is a constant and
531 the other is not, the constant's type is set to the type
532 of the other argument. If both are constants and one is
533 signed, the other is converted to a signed constant.
535 Sat Jun 29 17:26:29 EDT 1991
537 valarith.c Added a better range checker. It now checks range
538 (successfully) on integral operations [+-] (signed and
539 unsigned) for any C sized type. Still does not work well
541 int_in_size() returns an integer that is coerced to fit into
542 specified number of bytes.
544 Mon Jul 1 13:04:14 EDT 1991
546 language.[ch] Added the function binop_result_type(), which returns the
547 builtin (struct type *) type that would be the result of a
548 binop on the two values V1 and V2.
550 Wed Jul 3 19:22:53 EDT 1991
552 source.c Extended source_info() to include the source language in
553 the output from "info source".
555 Fri Jul 5 13:48:52 EDT 1991
557 utils.c Moved the support functions for the GDB set/show commands
558 dealing with language into language.c.
559 language.c Added the function language_info(), which displays info
560 about the current working language, type and range check
561 settings. Called via the GDB command "info language".
562 Added an initialization routine _initialize_language(),
563 that sets defaults for the language, type and range
564 variables and sets up the new GDB commands.
565 main.c Language setup moved to language.c.
568 Mon Jul 8 10:10:22 EDT 1991
570 valarith.c Debugged the range checker for arithmetic. Still does not
571 work for multiplication very well.
573 Mon Jul 8 12:40:37 EDT 1991
575 language.[ch] Added the function value_true() which returns non-zero if
576 its argument represents a boolean true value.
577 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
578 check the truth of an expression.
580 Thu Jul 11 12:51:34 EDT 1991
582 language.[ch] Added the predicate structured_type(), which returns
583 non-zero if the argument is a structured type.
584 Added the predicate pointer_type(), which returns non-zero
585 if the argument is a pointer type.
586 eval.c Added the ability to do addition and substraction on
587 pointers and integers. This case simply bypasses the
590 Thu Jul 11 14:41:42 EDT 1991
593 Added the symbol N_DEFD (0x4a) which is a definition
594 module dependency that is used by the GNU Modula-2
595 compiler and the linker. It is not important to GDB,
596 except that [dbx|coff|mips]read.c should ignore these
599 Fri Jul 12 16:07:00 EDT 1991
601 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
602 0 in val_print(). Also added statements to the else part
603 to coerce type (argument to val_print) to a pointer type
604 if it is an "array of unspecified length".
605 valops.c Added the function value_m2_string(), which returns a
606 (value) value which is a constant string, whose type is
607 (ARRAY [0..n] OF CHAR). The length field of the type
608 structure is set to zero, so it will be interpreted as an
609 "array of unspecified length".
610 stack.c Moved the language/frame mismatch check to
611 main.c:execute_command().
612 main.c The working language is recorded each time
613 execute_command() is executed. If working lang has
614 changed during its execution, then the new
615 language/type/range info is printed out for the user. If
616 the working language does not match the language of the
617 frame, a warning is issued.
619 Sat Jul 13 16:16:39 EDT 1991
621 eval.c Moved all the type-checking stuff for operators to
622 language.[ch] language.c. This is so we can keep language-specific
623 stuff (like for what type operators are defined) in
625 language.[ch] Added the function binop_type_check(), which checks to see
626 if its two (value) arguments are type-compatible with its
627 opcode argument. The opcode should represent an operation
628 involving an operator. Also added the macro function
629 unop_type_check, which calls binop_type_check with a
630 NULL second argument.
631 expprint.c Added Modula-2 operators to the op_print_tab, so info
632 expression.h break works correctly. Also added "op_string", which
633 returns the string corresponding to the (enum exp_opcode)
634 opcode that is its argument.
637 Sat Jul 13 18:26:18 EDT 1991
639 coffread.c Added code to record the type of function arguments with
640 each paricular function. Code is very similar to that
642 dbxread.c Moved add_param_to_type() to symtab.c
643 symtab.[ch] Added function add_param_to_type() from dbxread.c
645 *** NOTE: The above additions have not been tested.
647 Mon Jul 15 12:50:47 EDT 1991
649 langauge.[ch] Added the functions type_error and range_error, which work
650 like error() except if the type/range mode is set to
651 *_mode_warn, then they do not do a return_to_top_level(),
652 but merely print a warning.
653 Also changed [set|show]_[type|range]_command() to support
654 the new "warn" feature.
656 Thu Jul 18 17:50:54 EDT 1991
658 mipsread.c Added code to record the type of function arguments with
659 each particular function. Code is very similar to that
662 *** NOTE: The above additions have not been tested.
664 Fri Jul 19 11:19:10 EDT 1991
666 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
667 UMIN_OF_SIZE, which when given a size of a numeric type,
668 return the maximum and minimum value it can hold. UMAX...
669 and UMIN... return the result for unsigned types.
670 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
671 struct types. They call above macros.
672 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
673 avoid a name conlict with the above.
674 c-exp.y Added range checking on numeric constants in
675 parse_number() for completeness.
676 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
677 return 0 if working_lang is not language_c.
679 Thu Aug 8 14:17:22 EDT 1991
683 breakpoint.c Documentation strings of some commands changed to
684 eliminate the references to the C language where
687 Tue Aug 13 15:48:03 EDT 1991
689 m2-exp.y Added qualified identifiers to the grammar. The semantics
690 are slightly different from those of the GDB operator ::
692 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
693 type_exp, where type_exp is any valid type expression.
695 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
696 printcmd.c Modified ptype_command() so it actually parses the input
697 (necessary for type expressions with scope qualifiers).
698 Added the function ptype_eval() which expects an
699 expression composed of one OP_TYPE element.
700 *.[ch] Replaced all occurences of parse_c_expression with
702 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
704 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
706 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
708 Small fixes from Peter Schauer:
710 * infrun.c (child_attach): Lint.
711 * solib.c (find_solib): Handle shared libs version 2.
713 Small fixes from David Wood:
715 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
719 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
720 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
722 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
723 chars_per_line is at maximum (user typed `set width 0'). Fix
724 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
726 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
728 * coredep.c: include ptrace.h where necessary.
729 * mipsread.c(parse_lines): fix unsigned char problem that was
730 messing up line numbers on SGI's and possibly other MIPS based
732 * infrun.c (child_create_inferior): use better test to check
733 return val from setpgrp().
734 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
735 for sgi/irix support.
737 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
739 * mipsread.c (parse_symbol): Put non-static procedures
742 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
744 Patch together `text_start' and `text_end' for 29K port.
746 * exec.c (exec_command): If NEED_TEXT_START_END, define the
747 variables and set them based on the exec file.
748 * am29k-tdep.c: declare text_start.
749 * valops.c (call_function_by_hand): declare text_end.
751 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
752 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
753 because machines that do this will also have to know to
754 set NEED_TEXT_START_END. Besides, it was a redundant way to
756 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
757 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
760 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
762 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
764 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
765 Pass MUNCH_DEFINE to munch whenever we run it.
766 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
767 format string; use 0x%x instead.
768 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
769 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
770 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
771 * inflow.c: Handle `short' process group IDs.
772 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
773 and check for ptrace errors.
774 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
775 (coff_symfile_init): Initialize text_bfd_scnum.
776 (read_coff_symtab): Use it to find the text [and absolute?] sections.
777 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
778 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
779 Merge target arm case with other "easy" cases. Add target
780 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
781 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
783 * minimon.h, remote-adapt.c, remote-mm.c: Add.
784 * munch: Cope with RT/PC putting fns in data segment.
785 Restore ability to override `nm' by specifying MUNCH_NM.
786 * xconfig/rtbsd, xconfig/ultra3: New host systems.
787 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
788 and remote-adapt. Remove encapsulated coff #define's (the
789 support should go in BFD, and gdb shouldn't know or care).
790 * tconfig/a29k-kern: Same, but for remote kernel debugging.
791 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
792 * tm-29k.h: Update BADMAG (though it should go away).
793 Allow the register definitions to be overridden in another
794 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
795 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
796 DUMMY_SAVE_GR96, for handling kernel calling conventions
797 that use GR64+ rather than GR96+.
798 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
799 remote debugging of Ultra3 kernel. Includes tm-29k.h and
800 overrides various things.
802 * remote-mm.c (mm_attach, mm_wait): Handle attach like
803 child_attach does, making a clean stop in the newly attached
807 * coffread.c: Make coffread independent of any particular
808 variant of COFF. Avoid #include-ing any particular one except
809 internalcoff.h. BFD now passes key values for symbol reading
810 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
811 and the symbol masks and shifts); use them.
812 Remove obsolete end_of_text_addr.
814 * exec.c: Remove unused include files.
816 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
818 * Makefile.in (documentation targets): Pass $(M4).
819 Bugfix from eggert@twinsun.com (Paul Eggert).
821 * stack.c (down_silently_command): Check for stack existence.
823 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
825 * Makefile.in (VERSION): Update to 4.0.3.
827 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
829 * core.c (core_file_command): Print frame at coredump with
830 its level number, by calling print_stack_frame.
831 * frame.h: Add selected_frame_level, print_stack_frame.
832 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
833 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
834 Change print_sel_frame and print_selected_frame callers to
837 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
838 * symfile.c (free_named_symtabs): Ditto.
839 * main.c (main): wrap_here needs an arg.
840 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
841 (solib_add): Avoid noise.
842 (solib_create_inferior_hook): Lint.
843 (sharedlibrary_command): Move dont_repeat to here.
844 * utils.c (error): Call wrap_here to force buffered output.
846 Small patches from Peter Schauer:
848 * coffread.c (start_symtab): Free any existing line_vector before
850 (read_coff_symtab): Ditto for type_vector.
852 * source.c (lines_to_list): New variable, replacing function.
853 (all uses): Use as variable.
854 (_initialize_source): Add 'set listsize' and 'show listsize'.
855 * utils.c (lines_to_list): Remove function.
856 * stack.c (print_frame_info): Use as variable.
857 * defs.h (lines_to_list): Remove declaration.
859 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
861 * breakpoint.c (insert_breakpoints): Restore warning about
862 the program might be running in another process, but only for
863 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
864 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
866 * utils.c (error): if error_pre_print is set, print the string
868 * main.c (main, print_gnu_advertisement, print_gdb_version):
869 Reformat legalese so it always prints, but acts as an "I'm here"
870 message while symbols are being read. If any errors occur,
871 print a few newlines to set off the message and start it at the
872 left margin. Remove mention of "help" command, and don't yak
873 about symbol reading.
874 (catch_errors): Error string is now printed first in case of
876 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
877 suggest the "help" command.
879 * Makefile.in (VERSION): Set to 4.0.2.
881 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
883 * .gdbinit: Remove useless "rr" command. Set complaints
884 to 1 for people debugging gdb.
886 * breakpoint.c, remote-vx.c: Reword strings printed by
887 catch_errors callers.
889 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
891 * WHATS.NEW: "history write -> history save". Doc "write on/off".
892 (Fix from kenc@viewlogic.com.)
894 Fix some infrastructure to be able to cope with host and target
895 machines with different sized basic types (ints, ptrs, etc).
896 (Idea from pierre@la.tce.com (Pierre Willard).)
898 * values.c (value_from_longest): Rename from value_from_long.
899 Handle pointer types as well as integers, so that targets with
900 different pointer sizes from the host can be accomodated.
901 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
902 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
903 uses of value_from_long to value_from_longest.
904 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
905 the correct pointer type to value_from_long{est}.
907 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
909 * remote-vx.c: Remove obsolete code for calling functions via
910 vxworks kludge interface (it referenced value_from_long).
912 * valops.c (value_string): Find malloc with lookup_misc_func, not
915 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
917 Make writing to files work properly. (Fixes to BFD are also needed.)
919 * core.c (core_open): Open file ourselves, read or r/w, depending on
920 write_files. Use bfd_fdopenr.
921 * gdbcore.h (write_files): New variable.
922 * exec.c (write_files): Define variable, add set&show for it.
923 (exec_file_command): Use write_files to open for read or r/write.
925 Make shared library reading happen automatically. These changes
926 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
928 * inferior.h (stop_soon_quietly): Add to exported variables.
929 * infrun.c (child_create_inferior): call solib hook, if defined.
930 (child_attach): call solib hook, if defined.
931 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
932 (find_solib): Use lookup_misc_func rather than hand-rolled.
933 (symbol_add_stub): New stub for catch_errors.
934 (solib_add): Avoid output if !from_tty. Catch errors rather
935 than just calling symbol_file_add and bombing.
936 (solib_create_inferior_hook): Interface with the target process
937 to let it read and alloc shared libs, then figure out what it did.
939 * core.c (validate_files): Fix typo, soften warning.
940 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
942 * utils.c (fputs_demangled): Avoid duplicate printing if
943 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
945 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
946 (Fix from pierre@la.tce.com (Pierre Willard).)
948 * main.c (catch_errors): Change argument to a char * from an int,
949 since a char * can point to a struct full of glop, but an int
950 is not guaranteed to be able to hold a pointer.
951 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
952 breakpoint_re_set_one, breakpoint_re_set): Adapt.
953 * core.c (core_open, solib_add_stub): Adapt.
954 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
956 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
958 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
959 by adding .NOEXPORT target.
961 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
965 * Makefile.in (VERSION): Roll to 4.0.
966 (gdb.tar.Z): Make refcard.ps as well, for shipment.
968 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
970 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
973 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
976 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
978 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
979 reflect above name change
981 * WHATS.NEW: correct pointer to refcard.
983 * doc/gdb.texinfo: update New Features, Installing
985 * doc/gdbint.texinfo: add short description of configure +template
987 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
989 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
991 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
993 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
994 tar file, add dependencies for referenced doc files.
996 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
998 * coffread.c, symfile.c, stack.c: saberized.
1000 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1002 * doc/refcard.tex: permuted Essential Commands sec
1004 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
1006 set/show symbol-reloading
1007 default set complaints 0
1009 RET-repeat disabled after prompted long displays
1010 processID (attach) interpretation of 2nd GDB cmdline arg
1012 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1014 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1015 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1016 breakpoint.c, main.c: lint.
1018 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1020 Install new configuration scheme for GDB and friends.
1022 * config.sub: Translate ordinary names to three-part names.
1023 * configure: Use three-part names internally.
1024 * configure.in: Translate three-part names to filenames.
1026 * README, WHATS.NEW: Update for gdb-4.0.
1027 * Makefile.in: Roll VERSION to 3.99.
1029 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1031 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1032 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1033 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1034 to single structures rather than arrays; when passing
1035 their address, use &. This avoids trouble with bdead compilers.
1036 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1037 instead. This avoids portability headaches.
1038 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1040 * source.c (open_source_file): Avoid ANSI const bdeath by
1041 skipping declaration and then casting result value.
1042 * tm-hp300bsd.h: Clarify comment.
1043 * utils.c (strstr): Result is const char *; ANSI bdeath.
1044 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1045 since system include file defines it differently from "defs.h",
1046 though the two are equivalent for our purposes.
1047 * tconfig/hp300bsd: Add m68k-tdep.o.
1049 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1051 * tconfig/sun*4: Remove warnings about system assembler.
1053 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1055 * mcheck.c: Avoid warning about undeclared abort fn.
1056 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1057 it causes recursive calls to error() when used in cleanups.
1058 To do so requires that we make it a function, so we do.
1059 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1060 * utils.c (do_cleanups): Remove the current cleanup from the
1061 chain *before* calling it, in case error() is called from it.
1062 The result won't be pretty, but won't be an infinite loop either.
1064 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1066 * dbxread.c (read_struct_type): Grok anon structs for C++.
1067 (vb_name, vptr_name): Null terminate these strings.
1069 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1071 Minor bug fixes from BSD Net2 gdb:
1073 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1074 returns 0, there is no previous frame.
1075 * breakpoint.c (commands_command): If !from_tty, don't call
1076 input_from_terminal_p().
1077 * dbxread.c (record_misc_function): Speed up slightly.
1078 (compare_psymbols): Ditto.
1079 * infcmd.c (do_registers_info): Take a second argument to
1080 determine whether to print float registers. "info registers"
1081 does not do so anymore. "info all-registers" does, now.
1082 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1084 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1085 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1089 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1090 executing_breakpoint_commands if we are interrupted by error.
1091 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1092 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1093 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1094 catch_errors() so we can setup the frame regardless of whether
1095 the shared libs work.
1096 * ieee-float.c (double_to_ieee_extended): Get exponent from
1097 right place in little-endian systems. From John Carey.
1099 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1101 * main.c: Remove unused terminating_signals and catch_termination().
1102 (long_options): Terminate with a zero element.
1103 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1104 (gdb_readline): Make call-compatible with readline.
1105 (init_signals): Improve comments re vfork vs. signal.
1107 * utils.c (prompt_for_continue): Use new gdb_readline().
1108 If we prompt for continuation, we don't let CR repeat the previous
1109 command, once we get back to a prompt. It's too easy to keep
1110 hitting CR, expecting "--more--" prompts, and have some long
1111 command start repeating on you.
1113 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1115 * blockframe.c (frameless_look_for_prologue): Speed up by
1116 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1117 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1118 Define two variants, one faster.
1119 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1120 and return zero, rather than giving an error.
1121 (setup_arbitrary_frame): Initialize the PC in the new frame.
1122 (skip_prologue): Add a second arg saying whether we're just
1123 checking for a frameless function or not.
1125 * core.c (core_open, core_close, core_xfer_memory): Move
1126 section table pointers and bfd* into the target_ops.
1127 (core_open): Allow errors in shared lib reading, etc.
1128 (core_files_info): Describe shared library sections.
1130 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1131 exec_files_info, set_section_command): Move section table
1132 pointers and bfd* into the target_ops.
1133 (add_to_section_table): Add BFD to section table.
1135 * target.c (target_xfer_memory, target_info): Pass target to
1136 xfer_memory and target_info functions.
1139 * gdbcore.h: Move struct section_table.
1140 * target.h: New home of struct section_table.
1142 * solib.c (solib_add): New argument is the target_ops whose
1143 section list is to be added to, if any. Reallocate the
1144 sections in that target to add any that come from shared libs.
1145 (throughout) so_sections renamed to sections.
1146 (solib_xfer_memory): Deleted.
1147 * tm-sunos.h (SOLIB_ADD): Add target argument.
1148 (SOLIB_XFER_MEMORY): Delete.
1150 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1151 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1152 from target_ops. It's the same on all targets. Add two section
1153 pointers to target_ops.
1155 * stack.c (find_relative_frame): Dump ancient algorithm for
1156 "down", just use handy "next" pointers.
1157 (frame_command): Don't error if there is no stack; let user
1160 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1161 modifies static state in the parent process; new_tty itself
1162 runs in the child and modifies the child's file descriptors
1163 to match the saved static state.
1164 * infrun.c (child_create_inferior): Call new_tty_prefork,
1167 * infptrace.c (child_xfer_memory): Add ignored target arg.
1168 * remote-eb.c (eb_xfer_inferior_memory): ''
1169 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1170 * remote-vx.c (vx_xfer_memory): ''
1171 * remote.c (remote_xfer_memory): ''. Rename from
1172 remote_xfer_inferior_memory.
1174 * main.c (main): Only try to attach "corefile" argument if
1175 it starts with a digit.
1177 * symfile.c (symbol_reloading): New "set/show" variable.
1178 (symbol_file_add): Shorten message about symbol reading.
1179 (add_symbol_file_command): Merge with add_syms_addr_command,
1180 since this should work on all targets now.
1181 (stop_whining): Default to zero, to shut up complaints
1182 about bad symbol tables on many systems.
1183 (free_named_symtabs): Just exit unless symbol_reloading.
1185 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1186 and add comment explaining shared library screw.
1188 * source.c: #if defined => #ifdef.
1190 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1192 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1194 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1196 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1197 (doc/Makefile knows how to make one for local config)
1199 * Makefile.in: use doc/Makefile for doc targets
1201 * doc/Makefile: GDB documentation now has its own Makefile
1202 doc/refcard.tex: renamed from "gdbrc.tex"
1203 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1204 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1207 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1209 * values.c (baseclass_addr): When reading target memory, use the
1210 length of the basetype, not the upper type. We've only malloc'd
1211 enough space for the basetype, leading to errors in free().
1213 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1214 ends up as a function specially, since we know the actual type of
1215 the pointed-to address. This (somewhat) fixes display of
1216 expressions that include misc_function_vector names. Try `cond 1
1217 !strcmp("a","b")' then `i b'.
1219 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1220 The child can be proceeded from inside wait_for_inferior in
1221 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1222 getting skipped in that case.
1224 * expprint.c (print_subexp): Use filtered output, since the
1225 subroutines we call use it, otherwise the output is horribly
1226 mangled, since output of wrappable stuff comes out late.
1228 * Makefile.in: Bump VERSION to 3.98.1
1230 * infrun.c (child_create_process): Use execlp to find the
1231 shell to exec our target program. This requires some fiddling
1232 with `environ' since there is no execlpe().
1234 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1236 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1237 Minor rearrangement of refcard permits two new make targets--
1238 gdbrc.dvi DVI output for refcard, using CM fonts
1239 gdbrc.ps PostScript refcard, using PS fonts
1241 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1245 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1246 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1248 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1250 * doc/gdb.texinfo: last changes for release.
1251 Minor typo and formatting fixes; incorporated most fixes remaining from
1252 filed mail commenting on earlier drafts.
1254 Added warnings: pipes don't work in run command;
1255 conditions are converse of assertions;
1256 step over fn without debug info goes to next fn;
1257 vars may have "wrong" values near fn entrance, exit
1259 Added example from Kingston on printing repeated nonadjacent values
1261 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1262 shell mode for signals
1264 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1265 doesn't sound so much like its parent "Stopping and Continuing"; also
1266 moved entries on continue to top of section, so they don't get lost.
1268 Improved installation directions in appendix, added manual formatting
1271 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1273 * configure.in: Remove xm.h and tm.h even if we aren't linking
1274 new ones, so "./configure sun4; ./configure none" does the right
1275 thing. Assume that alldeps.mak and depend are already built in
1276 srcdir, and avoid running "make" (particularly "make depend",
1277 which involves "gcc") from inside configure. Build Makefile
1278 directly rather than building Makefile.conf first.
1279 * configure: Regenerate with above changes.
1280 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1281 to 3.98. Revise gdb.tar.Z procedure to produce a file
1282 called gdb-$(VERSION).tar.Z but which unpacks into a
1283 directory called "gdb". Move non-source files out of
1284 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1285 (depend): Don't try to do "gcc expread.y".
1286 (expread.o): Update dependencies by hand.
1288 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1291 Fixed a variety of small typos that prevented info from formatting
1292 cleanly; altered too-long heading for GPL Appendix, as discussed
1293 w/RMS; Changed date on cover to July 91.
1295 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1298 (1) Applied some fixes due to comments from Larry Breed (easier ones
1299 through chapsec 5.2)
1300 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1301 it's broken in latest texinfo
1302 (3) Introduced *some* use of [] for optional arguments, where
1303 explanation is not simpler by listing cmd w arg and cmd w/out arg
1304 separately. Still not using @deffn.
1305 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1306 couple of headings are too long. Need patches to texinfo or revision
1309 * Partial update to README (which still needs work for this
1310 release!): (1) use of configure corrected for new script,
1311 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1313 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1315 * symtab.c (lookup_symbol): Don't complain right off about
1316 no debug symbols; use the misc function vector first.
1317 (list_symbols): Use misc function vector to find symbols
1318 that don't have debug info, and print them.
1319 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1320 PC range doesn't match symtab PC range, as it does on the
1321 MIPS because our symtab reading isn't perfect.
1323 * dbxread.c (dbx_symfile_read): Make warning about
1324 "no debug symbols" slightly nicer.
1326 * source.c (select_source_symtab): If "main" symbol exists,
1327 but decode_line_spec can't find line info, don't just return
1328 a zero; try other source symtabs or give an error.
1330 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1331 their low addresses first, then rip through fixing high addrs.
1333 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1334 <runene@ifi.uio.no>.
1335 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1337 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1339 * Minor, mostly mechanical, cleanup of doc subdir for clean
1340 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1341 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1343 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1345 Mostly MIPS and general symbol-reading fixups.
1347 * doc/gdbint.texinfo: Add documentation on symbol-reading
1350 * mipsread.c: Remove kludges around #include "ecoff.h".
1351 Remove redefinitions of a_magic, etc, no longer used.
1352 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1353 Fix global overview comments to match symfile.c protocol.
1354 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1355 (mipscoff_symfile_read): Eliminate unused code. Avoid
1356 sorting all the symtabs, when all we have read here is psymtabs.
1357 The symtabs are sorted as they are created anyway. Tell
1358 condense_misc_bunches whether we're mainline.
1359 (psymtab_to_symtab_1): Pass filename when recursing, to make
1360 stack trace more informative.
1361 (parse_partial_symbols): Assume cur_hdr as argument.
1362 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1363 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1364 the TYPE_NAME of char *, since that's done in symfile.c.
1365 (free_numargs, parse_symbol, add_symbol, add_block,
1366 shrink_linetable): Declare these fns void.
1367 (upgrade_type): Convert tree of if's to switch. Clean up
1368 bogus "off == 0" handling with a complaint. Avoid setting
1369 field bitpos and bitsize of array with lower and upper bounds.
1370 Check specified bitsize of elements against their actual type's
1371 bitsize, and complain if different. Complain about unknown
1373 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1374 (psymtab_to_symtab_1): Print names of subsidiary files that
1375 are being read in. FIXME, we read far too many files. This code
1376 is not the problem, the problem is in parse_fdr where the psymtabs
1378 (cross_ref): Result should indicate that we used one aux entry
1379 normally, or two if we encountered a "next" entry. This used
1380 to leave the caller pointing at the wrong aux entry.
1381 (add_symbol): If overflowed cur_block, reallocate it larger,
1382 chase all pointers to it, and complain(), rather than clobber memory.
1383 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1384 (new_field): Only allocate one field initially, not two.
1385 Pull ++ out of macro argument. Simplify.
1386 (_initialize_mipsread): Avoid initialization of importd
1387 global_psymbols and static_psymbols.
1389 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1390 to properly set pst->symtab; avoid searching for it.
1391 (symfile_fns): Improve comments, add a FIXME.
1392 * dbxread.c: Update comments to reflect symfile protocol.
1393 (read_ofile_symtab, end_symtab): Return the symtab.
1394 (psymtab_to_symtab_1): Set pst->symtab.
1396 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1397 whether we're mainline.
1399 * symfile.h (sym_fns): Remove unused sym_discard member.
1400 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1402 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1403 the environment variable is not.
1404 * infcmd.c (finish_command): Use filtered printfs.
1405 * cplus-dem.c: Add struct tags to a few unnamed structs.
1406 * valops.c (value_coerce_array): Improve comments.
1407 * valprint.c (type_print_varspec_suffix): Print array size only
1408 if greater than zero.
1409 * m88k-tdep.c: Shift some lines left by one space, that had
1410 apparently been trashed at some point.
1411 * TODO: More things to do, a few got done.
1413 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1415 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1416 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1418 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1419 * expread.y, findvar.c, symmisc.c: Ditto.
1420 * printcmd.c (address_info): Update printed forms of LOC_
1421 symbols. Elim LOC_EXTERNAL.
1422 (print_frame_args): Keep track of param stack offsets before
1423 re-looking up to find the local register param is kept in.
1425 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1426 Further integration of mipsread into gdb. Eliminate unused
1427 routines, duplicate declarations. Handle static symbols in
1428 psymtabs as well as external symbols. When reading symtabs,
1429 insert symbols into the correct block (global, static, or a local
1431 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1433 (mipscoff_symfile_read): Don't call select_source_symtab.
1434 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1435 rather than SYMBOL_VALUE.
1436 (parse_external): Comment clobbering of top_stack.
1437 (parse_partial_symbols): Update comments. Allocate and parse
1438 static symbols as well as external symbols. FIXME, enum values
1439 are not handled in this pass, but should be. Inline new_psymbol.
1440 Use SYMBOL_VALUE_ADDRESS.
1441 (psymtab_to_symtab_1): Read symbols into global static block
1442 by default (until enter some function's local block context).
1443 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1444 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1446 * source.c (select_source_symtab): Select a source symtab
1447 from either the symtabs or, failing that, the psymtabs.
1448 (list_command): Update error message.
1449 (forward_search_command, reverse_search_command): Use getc, not
1450 fgetc, for speed. FIXME, add comment about buffers that die if
1451 overrun by long line.
1453 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1454 by an entire word, which is not portable, if we have a 32-bit
1455 field. (Code in dbxread.c already turns such bitfields, if
1456 aligned, into ordinary ints, but fixing this will help for other
1457 symbol formats and for future changes.)
1458 * core.c (core_open): Handle ANSI const brain death.
1459 * utils.c (vprintf): Fix varargs typo.
1461 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1463 * findvar.c (find_var_value): Handle &function better.
1464 * TODO: Document work needed on &fn and &array.
1465 * printcmd.c (print_address_symbolic): New arg is the prefix
1466 to print if a name is printed.
1467 (print_address_demangle): Honor "set print address" now.
1468 Use new arg above to improve spacing of output.
1469 * valprint.c (val_print): When printing function pointers,
1470 print symbolic form too.
1471 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1473 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1475 * core.c (memory_error): Reword error msg to mislead less.
1477 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1479 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1480 parse_partial_symbols): Use newer BFD internals (external_filehdr
1481 and external_aouthdr), byte-swap the fields that we care about
1482 before using them, and make the file header data local to
1483 read_the_mips_symtab rather than global.
1485 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1488 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1490 * main.c (command_line_input): Flush stdout and stderr
1491 before every call to readline. This reportedly fixes a bug
1492 that comes up in Sys V running emacs-gdb and/or xxgdb,
1493 when stdin/out are pipes or sockets.
1495 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1497 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1498 Avoid declaring Makefile dependencies, because GNU Make stupidly
1499 tries to update it if we do.
1501 * coffread.c: Revise for minor changes to bfd internal coff
1504 * configure: If -template= is given a relative path, make it
1505 absolute before recurring in subdirectories.
1507 * configure, configure.in, Makefile.in: Install "configure" script
1508 as replacement for config.gdb.
1509 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1510 * README: Update for configure, mostly. FIXME.
1512 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1513 target config files that they are for the host. When the lines
1514 get copied into the Makefile, this makes it more obvious what's
1517 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1519 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1520 tabs, which end up in the disassembler output inadvertently.
1522 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1524 Make it compile cleanly in an ANSI GCC2 environment.
1526 * blockframe.c: <stdio.h>
1527 * cplus-dem.c: free takes a void *, ifdef __STDC__
1528 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1530 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1531 * stddef.h, stdlib.h: Remove these files.
1532 * symtab.c: Avoid declaring qsort, close.
1533 * symfile.c: Avoid declaring close.
1534 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1535 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1537 Assorted other changes.
1538 * dbxread.c: include "libaout.h", not "liba.out.h".
1539 * printcmd.c (print_frame_args): Set recurse properly for
1540 indentation of struct and array parameters.
1541 * valops.c (value_cast): Allow cast to void.
1542 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1543 single_step() in a target-independent fashion.
1544 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1545 set up to be ready to continue. This makes us target independent.
1546 * infptrace.c (child_resume): Remove call to single_step; now
1547 can single step a SPARC target of any kind.
1549 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1551 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1552 docn into separate sections---basically chapters, plus two loose
1553 pieces that can be configured to go in different places. This
1554 allows GNU m4 to preprocess the manual without coredumping.
1556 * Makefile.dist: tell TeX where to find texinfo.
1558 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1560 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1561 the new target "rdl-apps.texinfo" which captures the Makefile
1562 variable that records where to find the Readline libraries.
1564 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1566 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

1568 * defs.h (const, volatile): Only define if not already defined.
1569 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1571 * README: Update for release 3.95.
1572 * config.gdb: Don't create readline dir in subdir builds.
1573 * main.c: Include with "..." form for non-system include files,
1574 so "gcc -MM" for "make depend" works.
1575 Include readline files with "...h" rather than <readline/...h>.
1576 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1578 * coffread.c: Undo minor damage done by Rich Pixley. Use
1579 different internal and external representations of COFF
1580 data structures. Use new BFD routines for swapping them in and
1582 * symfile.c (free_named_symtabs): Avoid freeing file names that
1583 are null or empty. Old i960 tools seem to produce files that
1584 claim to have empty names, causing each successive file read
1585 to blow away the previous one.
1586 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1587 Move deferred_stores to top of file, but don't separate its
1588 #define's from its variable. Add commentary.
1589 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1590 favor of keeping the (working) config.gdb. Move readline
1593 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1595 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1597 * infptrace.c (fetch_registers): no result, since now void.
1598 * tconfig/news: target depends on m68k-tdep too.
1600 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1602 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1605 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1606 applied various small fixes due to or inspired by RMS comments
1608 * doc/gdb.texinfo: finished using all RMS comments, save those for
1609 appendices on readline and cmd history (which are in other source
1612 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1614 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1615 chapter 9; (2) documented 'break' command's menu mode for
1616 overloaded names, in response to hgs problem report C++ p-31
1618 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1620 * doc/gdb.texinfo: (1) better introductory example; (2) more
1621 consistent use of @code, @samp, @file, @kbd throughout; small
1622 cleanups to first three nodes; (3) new "Contributors" node;
1623 (4) Appendix, Renamed Commands; (5) divert specialized startup
1624 instructions to "Targets" chapter for generic manuals, while
1625 leaving them up front for manuals specific to specialized
1626 environments; (6) apply fixes from RMS comments through chapter 4.
1628 * pretex.m4: modify explanatory text slightly (and redefine
1629 "regexp") to keep GNU m4 from complaining. (It still crashes
1630 later, but one step at a time...)
1632 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1634 * readline/readline.c (update_line): Avoid dereferencing a pointer
1635 before comparing it to its bounds. Saber caught this.
1636 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1637 and only set PC if tgetstr returned non-null. Saber caught this.
1639 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1641 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1642 stuff for config manual) here where it counts; updated
1643 to use new subdir structure (gdb/doc/).
1645 * Makefile: generated from above via
1649 * gdbint.texinfo: added instructions on generating gdb.info* files
1650 locally for release. These are ordinary info
1651 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1652 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1653 to generate these, so we distribute them already formatted.
1655 * gdb.texinfo: included full Info node and menu crud (as generated
1656 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1658 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1659 put in comments-for-future gdb.info target (one day makeinfo will
1662 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1664 * gdb.texinfo: Updated to include new or old undocumented
1665 commands, at least the following (perhaps some others I forgot to
1666 record): info f, info float, info path, info program, info s, info
1667 set, info source, info terminal, info types, info user, set/show
1669 Also covered all recent GDB command renames for v4.
1671 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1673 * mipsread.c: Rather than keeping count of how many symtabs
1674 and psymtabs we have, for sorting purposes, count them when
1675 we need to sort. This fixes bug in rereading of symbol tables.
1677 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1679 * infcmd.c: renamed "info path" to "show paths"

1694 symtab.h, target.c, target.h: Lint.
1695 * core.c: setup and select frame after reading shared libs,
1696 else reading shared libs will clobber them. Lint.
1697 * utils.c (error): Force out any buffered wrap text.
1699 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1701 * remote.c: Remove decls of memory_insert_breakpoint
1702 and memory_remove_breakpoint, no longer used. (Suggestion of
1705 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1706 to make it easier to interface to "configure"'d libraries.
1708 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1710 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1711 aliases for set/show print.

2260 been read in, particularly for VxWorks.
2262 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2263 to the main file, as well as to include files. Also, put global
2264 functions into the global psymtab, to make "i fun" work.
2265 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2266 new psymtab for it has been read.
2267 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2268 a file, once a new symtab has been read for it.
2269 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2270 looks harder to determine the top-level block before it's been
2271 queued to the psymtab list.
2273 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2274 If we have wiped out any old symbol tables, clean up at end of
2276 (symbol_file_command): Don't reference symfile_fns if it's zero.
2278 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2279 defines for the blocks of a blockvector that contain global and
2280 file-static symbols and the first of the smaller scope contours.
2281 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2282 decode_line_1, make_symbol_completion_list): Use the above.
2283 * coffread.c (end_symtab, patch_opaque_types): Ditto.

2289 * symtab.c (list_symbols): Process the first symbol of the
2290 static psymbols list.
2291 (types_info): Restore this function from its untimely #if 0.
2292 It's not perfect, but it is better than nothing.
2293 (_initialize_symtab): Restore "info types".

2297 * m68k-stub.c: Remote stub for 680x0's, created from

2304 * symmisc.c (free_named_symtab): Make it work, in its current

2307 free_named_symtab and print warning if we blew user's state.
2308 * symfile.h: free_named_symtab now returns an int.
2310 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2312 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2313 is the first symbol read, even if not mainline.
2314 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2315 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2316 (set_section_command): New command ("section xxx yyy" -- should
2317 be renamed to "set section xxx yyy" FIXME) which sets the
2318 base address of a section of the exec file, overriding the
2319 virtual address that BFD reports.
2321 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2323 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2324 load symbols at any address while examining an exec file.
2326 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2328 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2329 for printing the float info is host-dependent, not
2330 target-dependent. FIXME.
2331 * i386-pinsn.c: Move #includes to top, remove useless ones.
2332 * i386-tdep.c: Don't bother including <.../reg.h> since we
2333 don't use it (and it doesn't exist on host systems).
2335 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2336 Convert negative numbers properly.
2337 (ieee_test): Make numbers really random; fix format arg.
2339 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2340 * core.c (core_detach): Unpush core_ops, which might not be on
2341 top. We used to just pop the top, which broke things. Don't
2342 need dont_repeat() any more.
2343 (core_file_command): Psst! Don't repeat it.
2344 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2345 * expprint.c (print_subexp): Avoid switch fallthru on
2346 BINOP_ASSIGN_MODIFY, so we can print += and such.
2347 * frame.h: Fix typo.
2348 * inflow.c (kill_command): After killing inferior, print our
2349 current frame in the core file, if we have one.
2350 (generic_mourn_inferior): When inferior dies, either select
2351 the current frame (in the new target, e.g. core file), or
2352 set both the current and selected frames to NULL.
2354 Changes from Peter Schauer.
2356 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2358 * Make all file names fit in 14 characters (sigh and damn!):
2359 mv hp300hpux-xdep.c hp300ux-xdep.c
2360 mv symmetry-xdep.c symm-xdep.c
2361 mv symmetry-tdep.c symm-tdep.c
2362 mv convex-opcode.h convx-opcode.h
2363 mv tm-vxworks960.h tm-vx960.h
2364 mv tm-vxworks68.h tm-vx68.h
2365 mv Makefile.srcdir Makefile.sdir
2366 mv gdb-int.texinfo gdbint.texinfo
2367 mv remote-sa.m68k.shar rem-m68k.shar
2368 mv remote-multi.shar rem-multi.shar
2369 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2370 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2371 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2374 * command.c (user_info_1, user_info): New command for listing
2375 the user-defined commands.
2377 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2379 * dbxread.c (really_free_pendings): Clear file_symbols
2380 and global_symbols after freeing them; otherwise, running
2381 this function twice (if it appears twice on the cleanup
2382 chain), we try to free things twice.
2384 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2385 based on text_addr (the address of text in core), not on addr (the
2386 offset between text in the .o file and in core). This change
2387 is from Peter Schauer.
2389 * main.c: Define ALL_CLEANUPS as a cast of zero.
2390 (return_to_top_level): Use it.
2391 (main): Do all cleanups after each command run as part
2392 of the gdb startup sequence. Also do all cleanups before
2393 entering the command loop, and every time we exit the command
2394 loop and reenter. Before, the cleanups from the startup sequence
2395 were being left undone until the first error!
2396 (command_loop): Rename do_nothing cleanup to command_loop_marker
2397 so we can see it easily when examining the cleanup chain.
2398 (init_signals): Add another do_nothing for signal handling.
2399 (quit_command): Only try to kill target if it has execution.
2400 Problems in the target stack got us into a state where
2401 inferior_pid was nonzero but none of the targets had execution.
2402 In this state you couldn't exit gdb.
2404 * dbxread.c: Two changes from Peter Schauer.
2405 (echo_command): Fflush output after an echo command.
2406 (show_history): Pass all args to cmd_show_list.
2408 * utils.c (init_malloc): Call mtrace to turn on tracing
2409 if the environment variable MALLOC_TRACE is set to a file name.
2410 * mtrace.c: Add source file which provides a log of every malloc,
2411 free, and realloc to a trace file.
2412 * mtrace.awk: Add source file which analyzes the trace file.
2413 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2414 (VERSION): Roll to 3.94.3.
2416 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2417 (check_duplicates): Don't bother with watchpoints.
2418 (set_raw_breakpoint): Comment about danger of this routine.
2419 (watch_command): Parse and eval all args before calling
2422 * solib.c (find_solib): Avoid error in referencing memory to
2423 see if any more shared libraries have been added. This is
2424 particularly useful if the target has terminated. Bug reported
2427 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2428 in bringing up 3.94.2 on the Sun-3.
2430 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2431 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2432 expression (in scope) before reenabling watchpoint.
2433 * signame.c (init_sigs): Add missing declaration of i, fix
2434 sys_siglist declaration.
2435 * source.c (list_command): Fixed range computation to use
2437 * stack.c (backtrace_command): Do not allow command if target has
2438 no stack, print informative error message.
2439 * target.c (target_command): Do not write into command line
2440 because this fails if the target command is used in a user defined
2441 command. [This change was enhanced by gnu to support any-
2442 unique-prefix matching on target names.]
2443 * valops.c (value_struct_elt): Avoid infinite loop on an
2444 erroneous attempt to print the member of function (try p main.p).
2446 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2448 * expread.y (name_no_typename): Avoid reduce/reduce errors
2449 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2450 Since the GDB parser really doesn't use name_no_typename in a
2451 name-only context, the parser can't tell the diff between
2452 names and numbers here. Avoid allowing a name_no_typename
2453 to be a NAME_OR_*INT to resolve the conflict.
2455 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2457 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2459 * valprint.c (val_print_fields): bitfield printing didn't handle
2460 byte order. Indirect through a few more fns to cope.
2462 * values.c (modify_field): also cope with byte order.
2464 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2466 Cleanup for release 3.94.2:
2468 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2469 include files. Roll version to 3.94.2.
2471 * coffread.c (init_stringtab): Read length into unsigned char
2472 array before swapping; don't assume 32-bit longs.
2474 * target.c (target_info): Don't bother with get_sym_file, just use
2475 the symfile global variable.
2476 * symtab.h, symfile.c (get_sym_file): Delete it.
2478 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2479 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2480 (read_type): Replace one more error() with complain().
2482 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2484 * i960-tdep.c: Fix copyright attribution.
2486 * config.gdb: Quote all backquotes in doublequotes. You can
2487 quote me on that. BSD 4.4 shell found this one.
2489 * infptrace.c (throughout): The third argument to ptrace is an
2492 * infrun.c (wait_for_inferior): When program has terminated, we
2493 have to call target_terminal_ours before we pop that target off
2494 the stack (e.g. before a call to target_kill or
2495 target_mourn_inferior). This fixes problem where a program
2496 terminates, then GDB stops for (tty output) and you have to type
2497 "fg" to the shell to resume it. FIXME: This code for what to
2498 do after termination really should be in normal_stop instead.
2500 * gdbcore.h (read_memory_check): Change declaration; it changed
2503 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2504 4.4 prereleases, this avoids a bug in their sgtty compatability
2506 * remote.c: Use terminal.h rather than hand-rolling the same.
2508 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2509 * utils.c (strsave, strstr): Fix arg types.
2510 * valprint.c (val_print): lint
2512 MIPS symbol table support from Per Bothner:
2514 * symfile.c (symtab_fns): Remove initializer table that needs to
2515 be hacked for each new symbol file format supported.
2516 (add_symtab_fns): New function, chains symbol table
2517 handlers into the global list.
2518 (symfile_init): Search this list.
2519 * symfile.h: Add next pointer, declare add_symtab_fns.
2520 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2521 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2523 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2524 symbol *). Thus, we no longer need the hack to trash
2525 pst->filename. Good, since that hack confused code in symfile.c!
2527 (reorder_symtabs, destroy_all_symtabs): Removed static
2528 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2529 Instead, the latter now uses a temporary array (stack-allocated
2530 from an obstack, and then freed).
2532 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2533 haven't been set in the outermost stBlock of a procedure. This was
2534 a problem with f77 binaries on Ultrix 4.?.
2536 (new_symtab, new_symbol, new_type): Continue changing code to use
2537 obstacks more and otherwise conform to dbxread internal style.
2538 Made the free_code of symtabs be free_linetable (as in dbxread)
2539 instead of free_contents. This implies memory leaks when reading
2540 a new symbol table, until the conversion is finished. Did change
2541 (struct symbol) and (struct type) to be allocated on the
2542 symbol_obstack. Blocks and blockvectors are among the things
2545 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2546 tested much, but it solved one problem (reported by Meissner), and
2547 cleans up some other things. The problem happened when an
2548 included file contains actual code (functions) and not just
2549 definitions. The mips coff is a little inconvenient there, since
2550 it may cause a procedure to be mapped to the wrong psymtab.
2552 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2553 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2554 this will need work for the new core paradigm.
2556 Opcode patches from the net:
2558 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2559 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2560 missing altogether - they are added here. From Bruce Bauman.
2561 * mips-opcode.h: The low mask for C0 instructions was too small.
2562 From Garrett Lau. I modified the fix to check the entire 32-bit
2565 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2568 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2570 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2572 * dbxread.c (read_type): Pointer subtraction (value_sub in
2573 valarith.c) sometimes failed because the types of the
2574 pointers being subtracted were not identical.
2575 These differed because dbxread.c was allocating pointer types
2576 using dbx_alloc_type+smash_to_pointer_type instead of
2577 lookup_pointer_type. I failed to find a justification for the
2578 former, so I changed it to use the latter. Similarly, I
2579 replaced smash_to_function_type by lookup_function_type,
2580 and smash_to_reference_type by lookup_reference_type.
2582 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2583 _initialize_mipsread): corresponding changes.
2585 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2587 * source.c (mod_path): Do tilde_expand on each component of the path,
2588 rather than on the (list of) paths as a whole.
2589 (print_source_lines): Set first_line_listed in addition to
2590 current_source_symtab and current_source_line. If the source was
2591 not findable, after a "dir" command to fix the problem,
2592 a "list" would get the wrong lines.
2594 While I was there... (gnu):
2596 * dbxread.c (read_type): Change error to complaint.
2598 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2600 First attempt at detailed understanding of symbol table memory alloc.
2602 * dbxread.c (dbx_symfile_read): Free our string table if we
2603 aren't the mainline. Free the "info" struct since we're done with
2605 (init_psymbol_list): Free any previously allocated psymbol lists.
2606 (): FIXME: Should realloc-down the psymbol lists when done reading
2607 the main symbol file?
2609 * symmisc.c (free_symtab): Free fullname field too.
2611 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2612 (REGISTER_ADDR): Make result type unsigned int.
2614 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2615 define REGEX must also define REGEX1 (its dependency).
2617 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2619 * tconfig/i960: No longer works, points you at vxworks960 or
2622 * xgdb.c, XGDB-README: Remove file. Users can get the much
2624 * Makefile.dist: Remove all trace of xgdb.
2626 * breakpoint.c (breakpoint_1): Pass demangle arg to
2627 print_address_symbolic.
2628 (clear_breakpoints): Remove unused function.
2629 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2630 (breakpoint_re_set): Use catch_errors to do them all anyway.
2632 * gdb-int.texinfo (Host versus Target): Add section on what is
2633 a "host" feature versus what is a "target" feature.
2635 * infcmd.c (path_command, path_info): Handle the PATH variable
2636 (object search path) as conveniently as the source search path.
2637 * environ.c (set_in_environ): Set some vars in GDB's environment,
2638 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2639 * source.c (mod_path): New function, from guts of
2640 directory_command, modifies a path. Used by path_command.
2641 (directory_command): Call it.
2642 * defs.h (strsave): Declare.
2644 * utils.c (sevenbit_strings): Add new printing option.
2645 (printchar): Use it.
2646 (strsave): Provide this handy helper routine.
2647 (set_width_command): Rename set_screen_width_command.
2648 (_initialize_utils): "set screen-width" => "set width";
2649 "set screen-height" => "set height"; add sevenbit-strings.
2651 * infcmd.c (do_registers_info): Print floating point registers
2652 in raw hex as well as float format, regardless of whether it is
2653 a "virtual" convertible register.
2654 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2655 regs as a double, just in case it's being used that way.
2656 * values.c (unpack_long): Comment on array/function coercion.
2657 (unpack_double): Argument is in target byte order now. For
2658 integer arguments, just call unpack_long and float the result.
2659 * m68k-tdep.c: include defs.h for "const" handling.
2660 * remote-nindy.c: Use ieee-float stuff.
2661 (nindy_fetch_registers): Unpack double regs to host double, then
2663 (nindy_store_registers): Pack extendeds to host double, flip
2664 around by misusing unpack_double, send as target double.
2666 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2667 zero, as when stopped at the first instruction of a process.
2669 * blockframe.c: Fix filename in comment (param.h => tm.h).
2670 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2671 * tm-68k.h: Fix typos.
2673 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2675 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2677 * coredep.c (fetch_core_registers): Pass end-address of register
2678 section to register_addr as expected. Don't call supply_register
2679 if we'd just pass it garbage.
2681 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2683 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2685 * target.c (push_target, target_info): Cast enums to int for < or
2688 * stack.c (print_frame_info): Identify source file & line
2689 even if we can't print it.
2691 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2693 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2695 Clean up IEEE floating point support.
2697 * ieee-float.h: New file.
2698 * ieee-float.c: Write real routines to convert between host
2699 doubles and various target IEEE extendeds.
2700 * m68k-xdep.c: Eliminate assembler code for extended floats.
2701 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2702 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2703 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2704 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2705 double_to_ieee_extended.
2706 * i960-tdep.c: Define ext_format_i960.
2707 * m68k-tdep.c: Define ext_format_68881.
2708 * sparc-tdep.c: Define ext_format_sparc, though unused.
2709 * Makefile.dist (HFILES): Add ieee-float.h.
2710 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2713 Obsolete the "coffstrip" program in favor of using BFD's strip.
2715 * nindy-share/coffstrip.c: Remove file.
2716 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2717 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2718 * tconfig/nindy960: Remove reference to coffstrip.o.
2720 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2722 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2724 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2725 * dbxread.c: Remove static symfile_bfd.
2726 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2728 * inftarg.c (child_detach): Pop the child_ops vector if the
2729 detach is successful.
2730 * remote-nindy.c (nindy_create_inferior): Don't push a new
2731 nindy_ops since nindy uses the same one for execution and memory
2733 * core.c (core_ops): Use child_attach and child_create_inferior
2734 rather than default attach and create_inferior functions.
2736 Handle floating point registers in core files.
2738 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2739 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2740 This version untested since BFD doesn't yet support sun3 core
2742 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2743 conventions. Fix comments and style. This version has not
2744 been compiled yet, since we have no HP inhouse.
2745 * core.c (get_core_registers): Look for two sections, ".reg"
2746 and ".reg2", and pass both to fetch_core_registers sequentially.
2748 Revise directory path yet again.
2750 * source.c (forget_cached_source_info): Not static any more.
2751 (init_source_path): New default source path is "$cdir:$cwd".
2752 (dir_command): Handle variable arguments ($cdir, $cwd).
2753 (source_info): Print "Compilation directory" rather than
2754 "Originally compiled in" to remind people of $cdir.
2755 (openp): If the path contains $cwd, use current directory.
2756 (open_source_file): If compilation directory is known, replace
2757 first $cdir in path with the compilation directory.
2758 (print_source_lines): Even if we can't print the lines, set the
2759 current symtab and line for future commands like "info source" or
2760 "breakpoint". Also, error message now contains the file name,
2761 line number, and file access error message.
2762 (_initialize_source): Fix help text to describe changes.
2763 * main.c (cd_command): Forget cached source info when we chdir.
2764 * utils.c (strstr): Add simple implementation.
2766 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2768 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2769 Byte-swap COFF symbol tables if necessary when reading them in.
2770 Use complain() to replace error message in one spot. Needs
2771 corresponding change in bfd/coff-code.h to make some symbol
2772 swapping routines non-static.
2774 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2776 Merge changes from Eirik Fuller, for UTek.
2778 * defs.h (errno): Add declaration.
2779 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2780 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2781 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2782 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2783 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2784 declarations of errno.
2786 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2788 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2789 <rpc/rpc.h> and <rpc/types.h>.
2791 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2793 * i960-tdep.c (examine_prologue): Add new argument limit,
2794 which stops the scan at the end of the prologue, or at the PC.
2795 This fixes a problem where it walks down into the code for the
2796 user's statements if that code looks like function prologues.
2797 Mark Fox and I have been bouncing this code back and forth, making
2798 small changes to it. Callers changed to match.
2800 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2802 Cleanup for gdb-3.94 release final:
2804 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2805 the .c files from vx-share and nindy-share, from the various
2806 macros, since they are not found via ALLDEPFILES.
2807 (SFILES): Add tm-i960.h.
2808 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2809 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2811 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2812 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2814 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2816 * am29k-tdep.c: Add contribution line.
2817 (examine_prologue): Cache information about function prologues in
2818 the misc-function-vector to avoid lots of references over the
2819 serial line while examining instructions.
2821 * core.c (core_close): New function made from cleanup_core.
2823 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2824 remote-vx.c, remote.c, target.c, target.h,
2825 Update target_ops vector to add attach, close, and load entries.
2826 Use add_syms_addr_command, not add_file_addr_command, for
2827 add_file. Break out close routine from existing code.
2829 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2830 they are in an obstack.
2831 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2833 (define_symbol): Add symbol type parameter; change callers;
2834 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2835 it to influence the symbol class on the i960.
2836 (define_symbol): Swap LOC_CONST's into target byte order.
2838 * exec.c (exec_close): New function.
2839 (exec_file_command): Call it.
2841 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2842 Fix byte order of frame pointer.
2843 (read_var_value): Result of 0 if var's value can't be found,
2844 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2845 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2846 (locate_var_value): Use read_var_value and use its lazy address
2847 as the location of the var's value. Lint.
2849 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2852 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2853 obsolete Intel versions in favor of vxgdb versions.
2854 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2855 code dealing with byte order of values, which Intel did in host byte
2856 order rather than gdb-4's target byte order.
2857 (i960_frame_chain_valid): Move to nindy-tdep.c.
2858 (examine_prologue, skip_prologue, frame_find_saved_regs,
2859 frame_args_address, leafproc_return, saved_pc_after_call,
2860 pop_frame): Add vxgdb versions from Mark Fox.
2861 (examine_prologue, frame_struct_result_address): Add code
2862 to deal with the saved value of G13 (struct return address
2864 (frame_args_address): Modify Mark's version to prefer the
2865 saved value over the current value in the topmost frame.
2866 Cache result in the frame info to avoid performance hair in
2868 (print_fault): Add gdb960 code for printing faults.
2869 (_initialize_i960): Actually call check_host.
2871 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2872 add stub routines. FIXME, these currently just return zero!
2874 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2875 (attach_command): Call target_attach, not target_open, now.
2877 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2878 (child_attach): Rename from child_open.
2879 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2880 don't confuse it with a zero step_resume_break_address.
2882 * inftarg.c (child_detach): Eliminate inferior_pid test.
2883 (child_files_info): Clean up message a bit.
2884 (child_ops): Use child_attach, not child_open, to attach.
2886 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2887 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2888 findvar.c to here, since it depends on the contents of the
2889 shadow_contents of breakpoints, but keep if #if 0 since it is
2892 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2895 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2896 (ptype_command, display_command): Eliminate have_inferior_p and
2897 have_core_file_p in favor of target_has_stack or
2898 target_has_execution.
2899 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2900 code for actually finding the values of arguments, though we still
2901 keep track of the maximum stack offset for use in printing unnamed
2902 arguments. Handle missing FRAME_ARGS_ADDRESS.
2904 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2905 (struct nindy_regs): Define registers passed to/from nindy.
2906 (nindy_fetch_registers, nindy_store-registers): Translate between
2907 nindy and GDB formats for the registers.
2908 (dcache_init): Statically allocate the cache, since it was being
2909 allocated by a malloc that was never freed anyway.
2910 (nindy_create_inferior): Error, not core dump, if no exec file.
2911 (nindy_before_main_loop): Use target_load, not target_add_file.
2913 * remote-vx.c (net_load): Specify large timeout for load
2914 requests. Allow user to break out with INTERRUPT.
2915 (net_break): Remove useless code, clean up. Change callers.
2916 (parse-args, skip_white_space, find_white_space): Clean up arg
2917 parsing to cope with quoted strings.
2918 (net_wait, net_quit): Never call error, just return status.
2919 (vx_read_register, vx_write_register): Cleanup status checking.
2920 #ifdef the code based on which CPU we are using (960 or 68k),
2921 FIXME, this should be completely general but it isn't yet.
2922 (vx_xfer_memory, vx_resume): Cleanup status checking.
2923 (vx_run_files_info): Improve message.
2924 (vx_load_command): Renamed from vx_add_file_command. Allow load
2926 (net_ptrace): Remove unused routine.
2927 (vx_wait): Adopt code from vxgdb960 to cope with broken
2928 connections to target machine and prompt to disconnect. Remove
2929 debug printouts. Map some EVENT_'s to SIGnals.
2930 (add_symbol_stub, vx_open): Print names of object files we found,
2931 and "ok" if we read their symbols OK. Clarify output in general.
2932 (vx_attach, vx_detach, vx_kill): Add these commands.
2933 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2934 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2935 "info files" output, and create_inferior, since we already have
2938 * stack.c (frame_info): Replace Frame_unknown with 0.
2939 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2940 (return_command): Pop until the PC matches as well as the FP,
2941 so it works even if the FP is shared with another function,
2942 as in "frameless" or "leaf" procedures.
2944 * symfile.c (load_command): renamed from add_file_target_command.
2945 (add_syms_addr_command): renamed from add_file_addr_command.
2946 (add_syms_command): Stub to call target_add_syms.
2947 (_initialize_symfile): Change command names and descriptions,
2948 add-file => add-syms, and load from alias to its own command.
2950 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2951 maybe_kill_then_create_inferior): Default for attempts to start
2952 a process, if one is already running, is to ask about killing
2953 it and retry if yes.
2954 (upstack_create_inferior): #if-0 it, strata obsolete it.
2955 (push_target, unpush_target, pop_target): to_close() a target
2956 before unstacking it.
2957 (target_info): Renamed from target_files_info.
2958 (_initialize_targets): Rename "i files" as "i target", accessible
2961 * target.h: Improve comments about the target_ vectored routines.
2963 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2964 Convert commenting style to standard GNU style.
2965 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2966 (SKIP_PROLOGUE): No longer a no-op.
2967 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2968 (*_REGNUM): Sort register numbers.
2969 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2970 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2971 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2972 are now 10 byte extendeds, not 8 byte doubles.
2973 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2974 for nindy versus vxworks targets. FIXME, this should possibly go
2975 in the target vector.
2976 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2977 frame_saved_regs and arg pointer with each frame.
2978 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2979 (FRAME_ARGS_ADDRESS): Use cached result.
2980 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2981 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2982 (PRINT_RAMDON_SIGNAL): Call print_fault.
2983 (POP_FRAME): Now works.
2985 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2986 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2987 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2988 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2991 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2992 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2994 * valarith.c (value_subscripted_rvalue): Avoid handling
2995 floats and doubles specially; it gave alignment errors. Lint.
2997 * valops.c (value_of_variable, value_of_this): Error if unknown
3000 * valprint.c (print_floating): Bcopy rather than pointer-deref,
3001 to avoid alignment problems.
3002 (value_print): Handle unknown value address.
3003 (cplus_val_print): Two args are ignored; remove them. Change caller.
3004 (val_print): Use unpack_long rather than pointer-deref.
3007 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
3008 to avoid alignment problems.
3009 (value_being_returned): Error if return value unknown.
3010 (set_return_value): Add bogosity warning, FIXME. *
3012 * TODO: A woman's work is never done.
3014 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3015 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3016 Add ieee-float.o to OBS.
3017 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3018 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3019 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3021 Changes to generalize the VxWorks RPC protocol slightly, to handle
3022 i960 as well as 68000.
3024 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3025 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3026 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3027 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3028 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3029 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3030 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3031 so they will move in target byte order rather than network
3032 byte order (happens to be the same).
3034 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3036 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3038 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3041 Add contribution lines to various files, showing where they
3044 * breakpoint.c (break_insn, check_break_insn_size,
3045 read_memory_nobpt): Remove to mem-break.c.
3047 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3050 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3051 entry has bad register number. This change is not
3052 tested in this release, FIXME.
3054 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3057 * value.h: Force value's contents field to be aligned to hold
3058 at least a double or a long long (if supported). This avoids
3059 doing bcopy's in and out of the contents field.
3061 (step_1): Avoid coredump under obscure circumstances when we
3064 * symtab.h (misc_info): Add field to misc function vector for
3065 any kind of cached information the target code desires. AMD
3066 29000 uses this to avoid repeating examine_function_prologue's.
3068 * coffread.c: Lint. Remove static symfile, read_section_header.
3069 core.c (have_core_file_p): Lint: remove.
3070 expprint.c (print_subexp): Lint.
3071 infptrace.c, valops.c, valprint.c: lint.
3073 Roll in changes from vxgdb-5.0.1:
3075 * symtab.h: Comment byte order of each address class. Add
3076 LOC_LOCAL_ARG for frame-relative args (960).
3077 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3078 symtab.c, symmisc.c: ditto.
3080 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3082 * remote.c (remote_resume): Error if resume with a signal.
3084 * symfile.c (prim_record_misc_function): Clear misc_info.
3085 (fill_in_vptr_fieldno): Check stub type of arg.
3087 * valops.c (value_cast): Avoid looking up names of types whose
3088 name we don't know, to prevent coredump. Sun CC produces typedef
3089 rtx and the name of *rtx is zero...
3091 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3093 Roll in changes from final AMD 29000 port (Tiemann).
3095 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3096 for ../include/a.out.encap.h. This might not work now that BFD
3097 is separately compiled. Instead, BFD support for encap will have
3098 to translate machine type 29k into the right COFF_MAGIC.
3100 * infcmd.c: Remove references to inferior_pid that aren't used
3101 in actual ptrace calls; use target_has_execution, etc.
3102 (have_inferior_p): Remove function.
3103 (program_info): Print target info rather than "process number";
3104 avoid gratuitous messages unless from_tty.
3105 (run_stack_dummy, finish_command): Set proceed_to_finish.
3106 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3107 main.c: Lint. Lose have_inferior_p().
3108 inferior.h (have_inferior_p): Remove, lint.
3109 (proceed_to_finish): Add flag to ask that all regs be saved
3110 by normal_stop, for the few commands that need it, speeding up
3111 serial I/O. Add comments to stop_registers.
3113 * remote-eb.c: Remove newline from breakpoint message we grep
3114 for. Never time out when running the user program.
3118 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3120 Roll in changes from vxgdb-5.0.1:
3122 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3123 symbol in its raw form, we are processing an unlinked ".o" file.
3124 See if the target environment has assigned it an address, using
3125 target_lookup_symbol (VxWorks does), and enter it into the symtab
3128 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3129 68k versions for a simpler version that assumes zero FP at bottom.
3130 Fixes bug of truncated stack reports.
3132 * target.h (target_lookup_symbol): Define this routine's args
3133 and result, finally.
3135 * target.c (nosymbol): Default routine for target_lookup_symbol.
3136 (target_default): Default lookup_symbol and call_function too.
3137 (files_info): Only print has_all_memory warning if a non-dummy
3140 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3141 vx_convert_from_virtual): If target does not have floating point,
3142 zero register "values", and avoid doing cross-net conversions.
3143 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3144 (vx_open): Rearrange code that attaches to target and reads
3145 symbols for all loaded modules, to work if some of the modules
3146 are not accessible. Add symbol_stub() and add_symbol_stub()
3147 as callbacks from catch_errors(). Allow connect attempt to be
3148 interrupted painlessly with ^C (FIXME, there are still some bugs
3149 if the interrupt happens during symbol reading.). Print
3150 final message with puts_filtered, since symbol messages are
3155 * main.c (catch_errors): Only print errstring if non-null.
3156 (command_loop): Avoid an ioctl per command to test ISATTY.
3158 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3159 (vx_xfer_memory): Return correct result!
3160 (vx_files_info): Indicate whether target has float or not.
3161 (vx_lookup_symbol): Complain, not error, if target gone.
3162 (vx_open): Print "Connected" msg before disabling immediate-quit.
3163 [FIXME: lookup_symbol and vx_open changes need testing.]
3165 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3166 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3167 contributor lines and update copyrights to 1991.
3169 Changes from an attempted H-PUX host port:
3171 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3172 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3173 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3174 * remote-vx.c: include <sys/time.h> for HPUX.
3175 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3176 "core_file_command" routine to BFD regime. May not work yet.
3178 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3180 * xgdb.c: Replace X10 version with some VJ version.
3181 (FIXME: Its copyright assignment is not on record.)
3182 * xgdb.c: Update include files to X11R4 (Xaw crud).
3183 (xgdb_display_source, create_text_widget): fix call to
3184 get_filename_and_charpos. Rewack source window stuff for X11R4
3185 (gleaned from include files, and "nm's" of binary libraries, since
3186 I had no doc available).
3187 (append_selection, append_selection_word): Disable with FIXME
3188 since R4 changed interface here.
3189 (create_buttons): Add back the old set of buttons.
3190 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3192 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3193 Roll VERSION to 3.94 (not yet final though).
3195 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3197 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3198 obstack_int_grow, obstack_int_grow_fast): Eliminate
3199 cast on left of assignment, which gives MIPS cc fits and is
3202 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3203 F_ALIAS. Use printf, not fprintf, when not passing a file
3205 (compare_opcodes): Check that identical instructions have
3206 identical opcodes, complain otherwise.
3208 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3209 was reported by Roland McGrath.
3210 (unimp): Only match if exactly zero instruction. (Roland)
3211 (branches and traps): Generate all variations of these
3212 instructions with macros, based on a single call that defines
3213 each condition name and its binary representation.
3214 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3216 * valprint.c (val_print_fields): Take, and use, format parameter.
3217 This means that "p/x struct" again prints the elements in the
3218 desired format. Changed callers.
3220 * stack.c (frame_info): Use filtered output, and indicate wrap
3221 points. Remove kludgy formatting designed to avoid line wrap.
3223 * utils.c (wrap_here): If the line is already full (because
3224 we had printed a long indent or long wrapped string), do an
3225 immediate newline-and-indent.
3227 * m68k-pinsn.c (print_insn_arg): Bugfix from
3228 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3229 instruction is incorrectly disassembled as bkpt #8.
3231 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3232 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3233 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3234 and then will dump core (sometimes). I traced it back to an
3235 uninitialized symfile_name in psymtab_to_symtab.
3236 (const_vol_complaint): Add quotes to message.
3237 (define_symbol): Only believe line number if gcc_compiled.
3238 Avoid allocating symbol if we will not return it.
3240 Add target strata support so that newly established targets go
3241 into their right place in the target stack (e.g. a new exec file
3242 doesn't wipe out the ability to access the running process).
3244 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3245 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3246 and initialize it properly in all the targets.
3248 * target.h: Document strata. Change return type of push_target.
3250 * target.c (nomemory): new function for dummy memory access.
3251 (tcomplain): Rename complain, now also used in symfile.c.
3252 (push_target): Push targets within strata. New return value shows
3253 whether new target is on top of stack or not. Always keep dummy
3255 (target_files_info): Ignore dummy target.
3257 * core.c (core_open): Warn user, and skip accessing file, if the
3258 core target is not the topmost target in the stack.
3259 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3262 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3263 target_ops, it doesn't belong there since we have no regs there.
3264 Change name of target from machine => memory to clarify.
3266 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3268 * Freeze version 3.93 for release.
3270 * Makefile.dist: Handle vx-share and nindy-share subdirs
3271 properly when building gdb.tar.Z.
3273 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3274 printed in various places, so I could change just one copy.
3276 * dbxread.c, coffread.c: Change references to bfd->iostream
3277 to cast to FILE *, now that BFD avoids needing types defined
3278 in other header files.
3280 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3282 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3283 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3284 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3285 (actually gcc -Wall).
3287 * dbxread.c: Remove first_global_sym, last_global_sym, since
3288 they are never referenced.
3290 * defs.h (baud_rate): Declare.
3291 main.c: Define it, and add the -b option to set it.
3293 * gdb-int.texinfo: Add text on how to define a new host or target
3294 architecture, prompted by Per Bothner's questions about MIPS
3297 * gdb.texinfo: Document "complaints". Change doc of -q since
3298 gdb no longer prints the copyright and blurb if you specify a file
3299 name to be debugged (just like Emacs). Add doc for Nindy-specific
3300 command line flags for specifying target serial port and such.
3301 Update copyright to 1991.
3303 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3304 has taken over for us the job of ripping up executable files. The
3305 crud caused Per Bothner's port to not compile.
3307 * infrun.c (normal_stop): Avoid printing "Program exited
3308 normally" if we are in batch mode. This allows a GDB which
3309 executes a program on a target system, to behave like a Unix
3310 command (input from stdin, output to stdout, no extraneous
3313 * main.c (main): Allow additional machine-dependent command line
3314 options to be specified with the ADDITIONAL_OPTIONS,
3315 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3316 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3317 processing to occur just before the main loop with
3318 BEFORE_MAIN_LOOP_HOOK.
3319 (main): If a "core file" argument is specified, and it is not a
3320 core file, try it as a process ID to attach.
3321 (symbol_completion_function): Attempt to cope with
3322 "show screen-" TAB, not very successfully. This needs more work,
3324 (batch_file): New function, returns whether we are reading
3325 commands from an interactive tty on stdin, or from somewhere else.
3326 Called by normal_stop since it doesn't get from_tty passed down
3327 to it like many commands do.
3329 * remote-nindy.c: Handle command line options for nindy
3331 (nindy_before_main_loop): Prompt user for tty name if they
3332 don't specify it before getting to the interactive command loop.
3334 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3335 and -r command line options. Also add hook before main loop
3336 to make it easy to specify a tty.
3338 * TODO: More things to do, one done.
3340 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3342 * dbxread.c: Make complaint() calls pass pointer, not struct.
3343 Add complaints about badly formatted C++ type information
3344 (const/volatile indicator, and parse errors resulting in
3345 error_type). Fix C++ virtual member fn comment.
3346 (read_struct_type): Avoid bumping pointer if we got a parse
3347 error; this prevents our walking beyond the end of a string.
3348 Terminate loop on null char as well as semicolon.
3349 (process_one_symbol): Fix the LBRAC fix so that it uses the
3350 last previous SLINE, FUN, or SO record's PC address. C++ debug
3351 symbols did not have SLINE records in a useful order compared
3352 to the LBRAC records.
3353 (define_symbol): Handle "catch" records.
3355 * symtab.c (check_stub_type): Added new complain
3356 `stub_noname_complain' and added a consistency check to
3357 keep the debugger from crashing when finishing from an
3358 exception frame. A real fix will be needed later.
3360 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3362 * infcmd.c (attach_command): Make global.
3364 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3365 but make them easy to comment out. Perhaps later they should
3366 be enabled by what CPU you configure for? FIXME.
3367 (VERSION): Roll to 3.93.
3368 (pinsn.o): Remove rule for obsolete file.
3369 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3371 Run down a problem that manifested by printing the wrong function
3372 name in stack traces of read_ofile_symtab. Turned out that the
3373 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3374 the LBRAC symbol with an address in the *data* segment, which
3375 blew our binary search through the blocks.
3377 * dbxread.c: Use the complain() facility consistently to bitch
3378 about problems in the symbol file we are reading.
3379 (finish_block): Add code to check the nesting of the blocks;
3380 complain and Procrust them to fit if wrong.
3381 (make_blockvector): Check the order of the blocks, complain
3382 [but don't cope] if wrong.
3383 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3384 symbols to be sure their PC value is greater than the last SLINE
3385 (line number) symbol we've seen, complaining and adopting the
3386 SLINE PC value if wrong.
3388 * symfile.h (struct complaint, complaint_root, complain,
3389 clear_complaints): Add.
3390 * symfile.c (complain, complaint_root, clear_complaints): Add
3391 facility to deal with non-fatal complaints and to regularize their
3393 (symbol_file_add): Clear complaint counters to allow new complaints.
3394 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3396 * dbxread.c (dbx_symfile_read): Remember the address and size
3397 of the string table for the main symbol file, so we won't read it
3399 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3400 to avoid reading the string table yet again. Lint.
3401 (throughout): Improve filtered output, including word wrap.
3402 (read_range_type): Improve Bothner's fix to handle other types too.
3404 * utils.c: Improve line wrap implementation. Handle unlimited
3405 width by making chars_per_line unsigned.
3406 (puts_filtered): New, easy, function.
3408 * defs.h (puts_filtered): add.
3410 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3411 call the identical sort_symtab_syms() in symfile.c instead.
3413 * expread.y: Suggest the `file' command rather than `symbol-file'.
3415 * command.h (enum var_types): Add zinteger for seroable
3417 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3418 nested if's into a switch.
3420 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3421 we did not stop because of a breakpoint (it must have been for
3422 some other reason, like a "stepi"), so don't print anything.
3424 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3425 doesn't include <sys/types.h>, old SunOS's require it for
3428 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3430 A test port of gdb-3.92.6 to the Sony NEWS.
3433 Don't normally link in remote- or vx stuff.
3434 Some of it doesn't compile, and it wastes space for 99% of the users.
3435 Remove reference to no-longer-used HAVE_VPRINTF.
3436 Fixed BFD_DEP typo to BFD_DIR.
3438 Fix cast in arg to bfd_h_getlong.
3439 Make char *prefix be const.
3440 Fix how certain range types are mapped into builtin unsigned int types.
3442 Remove 2 #includes. They cause errors (on Sony, at least),
3443 and aren't needed (they wern't in earlier versions).
3445 print_address_symbolic should never demangle labels
3446 (since it prints *assembler-level* labels).
3448 [This was superseded by the change to printcmd below.]
3451 Add some "volatile" return types to avoid warnings.
3452 If MISSING_VPRINTF add vprintf function and not just macro
3453 (since vprintf is used in printcmd.c).
3455 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3456 (The latter isn't grokked by some PCC-based compilers.)
3458 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3460 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3461 * nindy-share/coffstrip.c
3462 Added some forward declarations (otherwise, gcc complains
3463 about implicit extern redefined as static).
3465 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3467 Changes inspired by Per Bothner:
3468 * printcmd.c (print_address_symbolic): Take additional parameter
3469 specifying whether to demangle.
3470 (print_address): Pass in asm_demangle to control demangling.
3471 (print_address_demangle): New fn, takes explicit arg to control
3473 * utils.c: Add new vars demangle and asm_demangle, and let them
3475 (fputs_demangled): If !demangle, just print the argument.
3476 (fprint_symbol): If !demangle, just print raw symbol.
3477 * valprint.c (val_print): Call print_address_demangle rather than
3478 print_address, to cause demangling to depend on the global
3479 rather than assembler-level demangling setting.
3480 * WHATS.NEW, gdb.texinfo: Document.
3482 * main.c (show_command): Show all settings if no arg.
3483 (initialize_main): Make "info set" the same as naked "show".
3484 * command.c (cmd_show_list): Handle prefix commands in the
3485 list, and print the name of the setting as well as its English
3486 description and value.
3488 Allow gdb functions to specify where a line should wrap if it
3489 exceeds the size of a terminal line. Use it to make the output
3491 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3492 of the right size when screen width changes.
3493 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3494 (wrap_here): New fn, indicates a point in the output where we
3495 should wrap the line rather than just letting it overflow at a
3497 (fputs_filtered): Implement wrapping.
3498 (n_spaces): New fn, returns a pointer to N spaces.
3499 (print_spaces_filtered): Use n_spaces.
3500 * defs.h (n_spaces): Declare.
3501 * stack.c (print_frame_info): Wrap with 4-space indent after
3502 fn name and before filename and line number.
3503 * printcmd.c (print_frame_args): Wrap with 4-space indent
3504 before each argument name is printed.
3505 * valprint.c (value_print): Wrap with no indentation before
3507 (val_print_fields): Wrap with indentation relative to nesting
3508 level before each field name.
3509 (val_print): Wrap with nesting indentation before array elements.
3510 * command.c (do_setshow_command): Avoid extra newlines,
3511 wrap with 4-space indent around values printed, end with period.
3512 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3514 * breakpoint.c (breakpoint_1): Implement addressprint for
3515 "info breakpoints" display. Change file name and line number
3516 format to " at file:nnn" rather than " (file line nnn)".
3517 * gdb.texinfo: Document.
3520 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3522 Frozen for gdb-3.92.6 release.
3524 README, WHATS.NEW: Update for 3.92.6 release.
3526 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3527 coffread.o from configs since it is now built by default.
3528 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3529 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3530 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3531 from configs since it is now built by default.
3533 Makefile.dist: Update for release 3.92.6. Handle files that
3534 have been moved to ../include, ../getopt, or ../bfd. Add
3535 saber.suppress and tests directory. Add config.status to
3536 the release (it will say "none").
3538 coredep.c: Minor formatting fixes.
3540 These changes were made in early December but only checked in now:
3541 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3542 nindy-share/nindy.c: lint
3543 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3544 register values coming back from the target; we store values
3545 in target byte order everywhere.
3547 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3549 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3551 * valprint.c (cplus_val_print, val_print_fields): New functions,
3552 which print C++ objects. They conspire to avoid printing a
3553 virtual base class more than once, following all the twists and
3554 turns of C++ virtual base rules.
3555 (val_print): Call the above rather than do it by hand.
3557 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3558 symbol file, not for added files like shared libs. This really
3559 needs to be generalized to a timestamp per file.
3561 * core.c (cleanup_core): Avoid coredump if no core file.
3563 * config.gdb: Accept -host or -target in place of +host or
3566 * coffread.c (find_linenos): Avoid desupported BFD interface
3567 to line numbers. We still read them manually rather than using
3568 BFD's "generic" features.
3570 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3572 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3574 * Makefile.dist: Eliminate use of $< in explicit targets.
3576 * readline/Makefile: Use $< rather than $*.c, which does not
3577 include the VPATH in GNU Make.
3579 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3580 copies of tconfig/i960, added for global configuration
3581 compatability. All i960 versions can read both coff and b.out.
3583 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3584 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3587 * TODO: Think of more things to do.
3589 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3591 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3592 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3593 64-bit float conversion.
3595 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3596 equivalent to sun?os4 so global config works.
3598 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3600 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3602 * main.c: Only declare linesize once; declare pagesize not at
3603 all, since it is never used.
3604 (main): Clear newly allocated line before it is used.
3606 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3608 Further stabilization for the Intel 960.
3610 * Makefile.dist: Parameterize the location of the "include"
3611 and "bfd" directories, as well as "getopt". Add symfile.c.
3612 Link in both dbxread and coffread. Fix up "make depend" to
3613 rewack the locations of include, bfd, and getopt in its output.
3615 * README: Document moving include files, improve some of
3618 * coffread.c: Move common code out to symfile.c. Change
3619 symbol_file_command style interface to use new *_symfile_init
3620 and *_symfile_read interface under BFD. Use BFD internal
3621 info to locate line table, symbols, etc.
3623 * core.c (core_fetch_registers): Rename to get_core_registers
3624 to avoid confusion with fetch_core_registers.
3625 (register_addr): Move to coredep.c, which is already machine
3626 dependent. This leaves core.c pretty clean of dependencies.
3628 * coredep.c (register_addr): Accept this routine from core.c.
3630 * dbxread.c: Move common code (with coffread.c, etc) into new
3631 symfile.c. Each psymtab now contains a pointer to the
3632 format-dependent function that knows how to read it in. Make
3634 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3635 (process_one_symbol): Add code to complain about a "compiler bug
3636 we muzzle here", if we actually see it.
3638 * eval.c (evaluate_subexp): Insert missing "break" statements
3639 in code that determines whether a variable is an lvalue in
3640 memory, register, or whatever. I detected this via a compiler
3641 bug in which it *almost* mashed out the whole switch statement.
3643 * gdb-int.texinfo: Add minor sections on configuring gdb for
3644 release, and about the README file.
3646 * infcmd.c (registers_info): Fix formatting somewhat. Still
3647 not as pretty as before, but it handles byte swapping.
3649 * remote-nindy.c: If data cache routines are interrupted while
3650 waiting for the remote end, be sure that any uninitialized cache
3651 blocks are on the free list, not on the valid list!
3653 * symfile.h: Flesh out this header file with all the various
3654 routines and variables that have been merged in from dbxread.c
3655 coffread.c, and symtab.c to symfile.c.
3657 * symfile.c: New file, containing code common to dbxread.c,
3658 coffread.c, and some code from symtab.c. All generic code for
3659 reading symbol files should be in here now.
3660 (unrecord_misc_function): Remove unused function.
3662 * symtab.h: Remove file-reading things to symfile.h.
3664 * symtab.c: Remove file-reading things to symfile.c.
3666 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3667 to decode i960 fault types.
3669 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3670 target.c: Change type of the "resume" function from int to void,
3671 since its result was never used.
3673 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3675 * main.c: Replace "stupid" with "caution"; you now "set caution
3678 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3680 * infcmd.c (do_registers_info): Call val_print to deal with the
3681 byte order of the registers being printed. FIXME, this makes
3682 the formatting of the output uglier.
3684 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3685 defined, call it for signals the debugger doesn't itself use.
3686 The i960 uses this for more detailed fault information.
3688 * remote.c (remote_open): If arg is null, print help rather than
3691 * sparc-xdep.c (register_valid): Avoid declaring size, since
3692 various modules will think of various sizes depending on the
3693 architecture of their tm-file. FIXME, we need protection against
3694 actually entering one of those modules, which would clobber
3695 storage if not for the target architecture compiled into gdb.
3697 * stack.c (up_command, down_command): Always print the frame
3699 (up_silently_command, down_silently_command): New commands
3702 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3704 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3705 more parameters than it used to.
3707 * findvar.c (registers): Increase slop to 256 bytes, which should
3708 protect us against even most RISC machines with large register
3710 (locate_var_value): Move declaration inside related ifdef.
3712 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3713 throughout, to avoid throwing away buffered input from the board.
3714 (nindy_wait): Supply_register takes addr_of_value, not value.
3715 (i960_print_fault): Renamed from i80960_fault.
3716 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3717 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3719 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3720 we can set the PC in the call to proceed(). Unpush nindy_ops
3721 before pushing it on top, to avoid message to user. Eliminate
3722 commentary from Unix machines that just misleads here.
3723 (reset_command): Fix error message to suggest target command.
3725 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3727 Release 3.92.5 as frozen.
3729 Stabilize the merged release...with help from lint, Saber C,
3732 Everywhere: Add include files needed to declare return types
3733 of functions called.
3735 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3737 * breakpoint.h: Add undeclared breakpoint functions, and some
3738 functions for display handling since I couldn't think of a better
3741 * breakpoint.c (insert_breakpoints): Make code for disabling
3742 shared library bkpts more likely to work. It's used when we
3743 rerun a program and stop before the shared library has been
3745 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3746 cast from pointer, so it squeezes through catch_errors.
3747 (bpstat_stop_status): Fix logic broken some time ago. We now
3748 always create a bpstat if the stop address matches a breakpoint,
3749 even if we don't stop there -- just like the old code used to do
3750 before I got my fingers into it (sigh).
3751 (breakpoint_1): Print "ignore count" after "stop only if"
3752 condition, since that's how it actually works.
3753 (mention): Handle watchpoints as well as breakpoints.
3754 (watch_command): use set_raw_breakpoint and mention to do most
3755 of the work (and initialize all the fields!). Only pass one
3756 arg to parse_c_expression, since that's all it takes.
3758 * command.c (not_just_help_class_command): Rename arg to args
3759 since we ignore "unused argument" warnings on vars named "args".
3760 inflow.c (child_terminal_info): ditto.
3761 infptrace.c (kill_inferior): ditto
3762 main.c (catch_errors, version_info, quit_command, pwd_command,
3763 source_command, dump_me_command, editing_info,
3764 set_history_size_command, set_history, show_history,
3766 stack.c (locals_info): ditto
3767 target.c (target_files_info): ditto
3768 valprint.c (set_input_radix, set_output_radix): ditto
3770 * core.c: Remove old variables for handling core and exec file
3771 sections (data_start, data_end, stack_start, stack_end,
3772 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3773 text_end, exec_data_start, exec_data_end, text_offset,
3774 exec_data_offset, data_offset, stack_offset). They're
3775 superseded the more general build_section_table and
3777 (get_exec_file): Mention the `file' command.
3778 (read_memory_check): Rename to memory_error, and only call it
3779 in the case of an actual error.
3780 (read_memory, write_memory): call memory_error.
3781 (core_fetch_registers): Register section name is ".reg".
3783 coredep.c: Remove a bunch of crud now that all this file does
3784 is pull the registers out of a core file.
3785 (fetch_core_registers): Rewrite to actually work, I hope.
3787 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3788 Replace index() with strchr(). Remove all the pre-BFD macro
3789 definitions for accessing the symbol file.
3790 (struct dbx_symfile_info): Encapsulate the information that
3791 dbx_symfile_init needs to pass to dbx_symfile_read in this
3794 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3795 dbx_symfile_discard): Rearrange symbol file reading to divide
3796 the format-specific part from the format-independent part,
3797 leaving the format-independent part such as file name expansion
3798 and opening in symtab.c. This replaces
3799 partial_symbol_file_open and partial_symbol_file_read.
3800 Symbol_file_read, add_file, add_file_target_command,
3801 add_file_addr_command move to symtab.c. Pass an explicit
3802 "mainline" flag for when reading the main symbol table, rather
3803 than relying on the offset address to be zero or nonzero.
3805 (dbx_symfile_read): Don't allow void *'s to be printed as
3807 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3808 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3809 macro" debug version really work.
3810 (read_dbx_symtab): Remove unref'd parameter inclink.
3811 Avoid swapping N_SLINE symbols, for speed.
3812 Merge N_TEXT!N_EXT case with the other external symbol
3813 definitions' case. Add comments.
3814 (start_psymtab): Allocate the symfile name in the psymtab on
3815 the psymbol_obstack, rather than using the caller's storage.
3816 (end_psymtab): Only allocate a dependencies list if there are
3818 (psymtab_to_symtab_2): Use BFD when reopening file to read
3819 its symbols for real.
3820 (read_struct_type): Add FIXME comments where it needs work
3822 (read_huge_number): Add FIXME about overflows.
3823 (read_range_type): Add FIXME about comparing a long to 1<<32.
3825 * coffread.c: Minor changes to move things closer to the new
3826 regime with symtab.c and dbxread.c Major work is still needed
3829 * exec.c (exec_file_command): Remove old variables (see core.c
3831 (xfer_memory): If memory transfer is right at the end of a
3832 section, don't lose.
3834 * findvar.c (get_saved_register): If value is in a real
3835 register, LVAL is lval_register, not lval_memory.
3837 frame.h: Declare print_sel_frame and record_selected_frame.
3839 gdb-int.texinfo: New file, for GDB internals documentation.
3840 Very simple, unformatted doc of cleanups is there for now.
3842 gdbcore.h: Remove obsolete variables that described a.out
3843 section addresses and offsets. (See core.c above.)
3844 Declare fetch_core_registers and registers_fetched.
3846 getopt.c: Declare char *alloca(); even on SPARC.
3848 infcmd.c (run_command): Call target_kill rather than
3850 (step_command, next_command, stepi_command, nexti_command):
3851 Declare from_tty parameter even though we don't use it.
3852 (run_stack_dummy): argument BUFFER is a char array, not
3853 a pointer to REGISTER_TYPE.
3854 (finish_command): using_struct_return needed a value *,
3855 not a struct symbol *.
3857 * infptrace.c (child_xfer_memory): To avoid dependency on
3858 where sections are in memory, try PT_WRITE_D and if that fails,
3859 try PT_WRITE_I. Most Unixes don't care which you use.
3861 * infrun.c (step_resume_break_shadow): Change to array to
3862 match other breakpoint shadow storage.
3863 (clear_proceed_status): Pass address of bpstat to
3864 bpstat_clear, not the bpstat itself.
3865 (child_create_inferior): FIXME comment about if the child
3867 (start_inferior): Remove old function.
3868 (child_open): Use target_kill rather than kill_inferior.
3869 (wait_for_inferior): Ditto.
3870 (insert_step_breakpoint, remote_step_breakpoint): Use
3871 new step_resume_break_shadow.
3873 * inftarg.c (child_wait): If all child processes die,
3874 pretend that the one being waited for exited with signal 42.
3876 * main.c (command_line_input): When scanning for comments,
3877 don't coredump on unclosed quotes.
3878 (quit_command): Use target_kill rther than kill_inferior.
3879 (_initialize_main): Rename class_user from "user" to
3882 * printcmd.c (print_command_1): Initialize "fmt" if no format
3883 is specified by the user.
3884 (print_frame_args): Only add to args_printed if we are
3885 actually fetching args from the stack (avoiding undefined
3887 (_initialize_printcmd): Remove bogus \{ from string.
3889 * remote-eb.c (eb_open): Avoid coredump on no argument.
3891 * remote-nindy.c: Bring out of Intel environment into new
3892 target environment. Remove all conditional compilation on
3893 I80960. Massive hacking throughout.
3894 (nindy_xfer_inferior_memory): New routine stolen from
3896 (nindy_create_inferior): New routine pieced together, probably
3897 not quite working yet.
3898 (nindy_ops): New target_ops struct for nindy.
3900 * remote-vx.c: Use write_memory rather than target_write_memory
3901 to get error checking.
3902 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3904 (vx_create_inferior): Use target_terminal_ours...
3906 * signame.c (_initialize_signame): Always initialize, since
3907 we need the table for things other than psignal.
3909 * solib.c (solib_add): Use symbol_file_add, not add_file.
3910 (solib_address): Return boolean result rather than struct
3911 pointer which nobody else knows the type of.
3913 * sparc-tdep.c, valops.c: Use write_memory rather than
3914 target_write_memory, to get error checking.
3916 * stack.c (locals_info, catch_info, args_info,
3917 get_selected_block, frame_command, up_command): Use
3918 target_has_stack, rather than have_inferior_p or
3921 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3923 * symfile.h: New file, defining the interface between the
3924 generic and object-file-specific symbol reading code.
3926 * symtab.c: Move generic symbol-reading interface to symtab.c,
3927 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3928 table to map BFD targets to symbol-reading modules in GDB.
3929 Change index to strchr.
3930 (lookup_struct_elt_type): Use error() rather than hand-made
3931 simulations thereof.
3932 (lookup_partial_symbol): Speedup slightly when length == 0.
3933 (symbol_file_add): New function.
3934 (symbol_file_command): Call it.
3935 (symfile_open, symfile_init): New function.
3936 (add_file_target_command, add_file_addr_command): moved from
3939 * target.c (target_command): use target_kill.
3941 * target.h (target_files_info): Don't declare, never called
3944 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3945 files to determine stack end address.
3947 * valarith.c (value_x_binop, value_x_unop): Change error message
3948 to be more useful. Pass proper argument to value_struct_elt.
3950 * valops.c (value_assign): FIXME comment that long long
3951 bitfields will break here.
3953 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3954 Update `make saber_gdb' to work better.
3956 * TODO: A woman's work is never done.
3958 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3959 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3960 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3961 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3962 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3963 valops.c, valprint.c, exec.c: Lint.
3966 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3968 Continuing Intel 960 port merge of GDB.
3970 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3971 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3972 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3973 Wack over "make depend" so it handles files in subdirectories
3974 vx-share, nindy-share, bfd, and in the current directory.
3976 * blockframe.c (get_prev_frame_info): Remove fatal error
3977 if stack not defined.
3979 * core.c (core_open, core_detach): New functions that handle
3980 the old "core-file" command as "target core" and "detach" instead.
3981 (core_file_command): Call them.
3982 (core_xfer_memory): Use common routine xfer_memory.
3984 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3985 dbxread now uses bfd for everything but symbol reading itself.
3986 BFD internals are used to drag out the relevant file offsets.
3987 (partial_symbol_file_open): Change args all around for BFD.
3989 * symtab.c: Rename "value" to "val" everywhere, so we can
3991 (symbol_file_command): New command, moved from dbxread.c
3992 and coffread.c. It uses BFD to read the file, then vectors
3993 based on its type, to dbx or coff symbol readers.
3994 * symtab.h: Extern a few vars for symbol_file_command.
3996 * target.h: Breakpoint takes a char * save area, not a char **.
3998 * valprint.c (val_print): When unpacking bitfields, offset
3999 the address in gdb of the value, if it is declared with a shorter
4000 type. Remove the last "runtime kludge test" of host byte order.
4002 * utils.c: Remove old my_bfd_read routine.
4004 * stack.c (frame_info): Use target_has_stack. Print program counter
4005 register's actual name rather than "pc", since it's called the
4006 "ip" (instruction pointer) on the i960 (sigh).
4008 * target.c (target_command): Add command for selecting a target
4009 type and calling its open routine. This is used for initiating
4010 communication with a particular target, in a generic way.
4012 * tm-i960.h: Update for modern gdb. Remove semicolons from
4013 various macros. Handle reading struct return convention, and
4014 error-out attempts to return structs with the "return" command.
4015 Be sure gdb doesn't think we know how to call functions in the
4018 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4019 to i960_xxx in lower case.
4020 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4021 not being defined yet.
4023 * remote.c (remote_open): Call start_remote to initialize
4024 wait_for_inferior during open.
4025 (remote_xfer_inferior_memory): Return length written rather
4028 * remote-vx.c (target_command -> vx_open): Use new generic
4030 * remote-eb.c, inftarg.c, exec.c: ditto.
4032 * infrun.c: Fix comments.
4033 (attach_program -> child_open): Use new generic target command.
4034 (wait_for_inferior): Clear saved register values before target_wait,
4035 so target_wait can set some of them if convenient.
4037 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4038 Return success indicator, not void.
4039 (child_xfer_memory): Avoid fetching initial word if we'll
4040 overwrite it anyway.
4042 * infcmd.c (attach_command): Use new generic target open routine.
4043 (_initialize_infcmd): Update doc on attach and detach commands.
4044 (do_registers_info): Merge in a byte-order problem as a FIXME
4047 * findvar.c (find_saved_register): Avoid problem in current frame.
4048 (read_relative_register): Ditto.
4049 (write_register): Convert byte order on the way out.
4051 * exec.c (file_command): Add.
4052 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4053 (xfer_memory): Common function between core_xfer_memory and
4055 (exec_xfer_memory): Use it.
4057 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4059 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4060 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4061 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4063 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4065 Merge Intel 960 port of gdb, continuing...
4067 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4068 symbol_file_command): Pass from_tty arg to hush 'em up.
4070 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4071 Add magic numbers for 960 COFF format.
4073 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4075 Merge Intel 960 port of gdb, from Intel "1.2" release.
4077 CHANGE_LOG entries from their port, which was based on
4080 Thu Sep 6 11:02:22 PDT 1990
4081 Remove temp file if download is interrupted.
4083 Wed Aug 1 09:08:33 PDT 1990
4084 Now uses binary protocol to talk to NINDY.
4085 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4086 Times out after 5 seconds when trying to talk to NINDY.
4088 Tue May 29 12:54:49 PDT 1990
4089 Added variable baud rate (-b switch).
4090 Source code reorganization.
4092 Thu Apr 26 11:09:55 PDT 1990
4093 More cleanup of batch mode; specifically, execute "-s", "-e", and
4094 "-se" switches as soon as they are encountered on the invocation line.
4096 Fri Apr 20 13:47:15 PDT 1990
4099 Thu Apr 19 09:54:28 PDT 1990
4100 Add 'reset' command.
4102 Wed Apr 18 09:48:07 PDT 1990
4103 After opening remote tty, wait for 1 second to go by without input
4104 from it before trying to talk to NINDY (fixes problems with the
4105 Heurikon HK80/V960E).
4107 Mon Apr 4 16:33:05 PDT 1990
4108 Some output was not being suppressed in 'batch' mode.
4110 Thu Mar 22 15:31:11 PST 1990
4111 Ask user if old symbol table should be deleted when new file is
4114 Allow user to run a program downloaded before gdb960 was brought up.
4116 Correct "exec-file" help message for i80960 context.
4118 Correct bug in calculating user space address: could occasionally
4119 corrupt user program.
4121 Make sure to zero low-order bits in rip's because of bug in 960CA
4122 A-step part: could cause operation faults when "next"ing across
4125 Correct bug that made it impossible to get source line numbers for
4126 code loaded at addresses higher than 0x7fffffff.
4128 Wed Jan 10 12:43:22 PST 1990
4129 Open remote tty for exclusive use.
4131 Fri Jan 5 12:14:42 PST 1990
4132 Correct disassembly (CA manual was right after all):
4133 opcode for sysctl is 0x659
4135 Mon Oct 23 12:03:04 PDT 1989
4136 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4138 Mon Oct 16 14:15:09 PDT 1989
4139 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4141 Mon Oct 2 15:56:31 PDT 1989
4143 Added 960CA disassembly support.
4145 To simplify maintenance:
4146 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4148 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4149 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4150 - made disassembly interface identical to that in gdmp960.
4154 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4156 * target.h: Allow targets to stack. Add target_has_memory,
4157 _registers, etc. Restructure memory access and "info files"
4158 to walk the target stack.
4159 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4160 target.c: Change tables to match target.h.
4161 * inflow.c (child_mourn_inferior): pop child_ops.
4162 (generic_mourn_inferior): Use new has_stack flag.
4163 * infptrace.c (child_xfer_memory): New memory regime.
4164 * inftarg.c (child_files_info): New "info files" regime.
4165 * remote-eb.c: New memory regime, new info files.
4166 * remote-vx.c: New memory regime, new info files. Now use
4167 separate targets for VxWorks attachment to machine, and
4168 actually running a process under VxWorks, since one has
4169 stack & execution & regs and the other doesn't.
4170 * remote.c: New memory regime, new info files.
4171 * sparc-xdep.c (fetch_core-registers): New memory regime.
4172 * target.c: New routines and support for stacked targets,
4173 new memory regime, new info files regime.
4176 Generalize section handling for an arbitrary number of sections,
4177 including use of the new BFD (binary file) library.
4178 * gdbcore.h: Add struct section_table.
4179 * exec.c (build_section_table): Iterate all sections and
4180 record what gdb needs to know about them.
4181 (exec_command): Use it.
4182 (exec_xfer_memory): Use the table.
4183 (exec_files_info): Print the table.
4184 * core.c (core_file_command, core_xfer_memory, core_files_info):
4186 * source.c (find_source_lines): Use bfd_get_mtime.
4187 * dbxread.c: Quick changes to make it compile with new BFD.
4188 * utils.c (error): Avoid using bfd_error in generic routines.
4190 * core.c (core_fetch_registers): Get from the ".regs" section of
4192 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4194 * inferior.h (attach_flag): Export.
4195 * infcmd.c (run_command): use new target_create_inferior.
4196 * infrun.c (child_create_inferior): Don't return result.
4197 * Makefile.dist (VERSION): 3.91.4.
4199 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4201 * breakpoint.c (bpstat_num): Handle breakpoints which have
4202 since been deleted, such as temporary breakpoints.
4203 infcmd.c (program_info): ditto.
4205 * core.c (core_file_command): Display the frame where the core
4210 * remote-vx.c (target_command): Merge in target command from
4211 targ-vx.c. A few other cleanups.
4213 * TODO, Projects: Lots more stuff to do...
4215 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4217 Massive changes to wall off the remote-debugging interface
4218 behind a function vector. The port to handle VxWorks targets
4219 is also part of this.
4221 All files: Replace references to renamed functions,
4222 remove references to remote_debugging, remove references to
4223 have_include_file, have_core_file in favor of target_has_stack,
4224 target_has_memory, etc.
4226 * Modularize the breakpoint interface.
4227 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4228 a breakpoint instruction.
4229 breakpoint.c: struct breakpoint's shadow_contents now sized as
4231 (insert_breakpoints): Vector to target to install breakpoints.
4232 (remove_breakpoints): Vector to target here too.
4233 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4234 sparc-tdep.c (single_step): Use new breakpoint interface for
4235 the single-step breakpoints.
4236 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4237 New file, contains routines to insert and remove breakpoints by
4238 reading out the old contents and later replacing them. This is
4239 how ptrace breakpoints work, and many remote systems as well.
4241 * tm-vxworks68.h: New config file, overrides a few things for
4242 Wind River's preferences.
4244 * target.h: New file, for transfer vector used to talk to the
4245 inferior (child, attached, core, exec, remote, etc). All accesses
4246 to the thing being debugged should come through these vectors.
4247 target.c: New file, routines to handle transfer vector.
4248 (various files): Add transfer vectors XXX_ops for the various
4249 targets and pseudo-targets (core files, etc) we support.
4251 * breakpoint.c (bpstat_stop_status): Further explorations of
4252 watchpoints and why things don't work all the time.
4253 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4255 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4256 the local gdbinit if it doesn't already have it.
4258 * core.c (core_ops): add and install.
4259 Allow core debugging without exec file.
4261 * dbxread.c (free_and_init_header_files): Merge two fns.
4262 (end_symtab): Free named symbol table when a new version comes in.
4263 (read_dbx_symtab): Relocate all kinds of symbols with base
4264 address. First step toward handling different text, data, bss
4266 (add_file_addr_command): Renamed add_file_command.
4267 (add_file_command): Vector to remote handler.
4268 Add "load" as an alias for "add-file" command.
4270 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4271 non-returning functions.
4273 * exec.c: Add exec_ops, and push it as a target when an exec
4276 * infcmd.c (run_command): Pass executable file name and arg list
4277 separately when starting an inferior. Permit "run" when no exec
4278 file is specified, for VxWorks.
4279 (detach_command): Move to child_detach in inftarg.c.
4281 * inftarg.c: New file. Unix-child-specific routines, and the
4282 child_ops structure.
4284 * inferior.h (registers): Export "registers" as the way for
4285 target dependent register handlers to find gdb's local copy of
4286 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4287 since it is now used by places that want wait_for_inferior to
4288 handle the grunge but want to see every trap from the inferior.
4290 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4291 Eliminate remote_debugging hooks in terminal handling.
4293 * infrun.c: Replace start_inferior with child_create_inferior.
4294 Move all the hair of Unix shells and ptrace idiosyncracies into
4295 child_create_inferior, so remote handlers don't have to deal.
4296 Remove running_in_shell. Rename stop_after_attach to
4297 stop_soon_quietly, and use it in a few other places where we want
4298 to just call wait_for_inferior and get control back on the first
4299 trap. trap_expected now never takes a value > 1.
4300 (init_wait_for_inferior): Initialize static vars when a new
4303 main.c (gdbinit): Add new hook for .gdbinit file name, let
4304 it be overridden by config files as GDBINIT_FILENAME.
4305 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4306 Both of these are used for VxWorks gdb.
4308 mcheck.c: rename include file "gmalloc.c" to avoid problems
4309 with system include file "malloc.c".
4311 param-no-tm.h: New include file, same as param.h but does not
4312 include the default "tm.h" file. This is used in files where
4313 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4315 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4317 remote-vx.c: New file, VxWorks remote debugging support. Uses
4318 RPC routines that are shared with the target system, in directory
4321 remote.c: Vectorize remote interface.
4323 source.c: Globalize source_path, and make an alias "l" for "list"
4324 since we now have the "load" command.
4326 sparc-xdep.c: Use new param-no-tm.h.
4328 symmisc.c (free_named_symtab): Add new function from Wind River.
4329 However, ifdef it out for now while we think about what it should
4332 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4334 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4335 non-Unix-children handle this with their own code in the target
4338 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4339 source and target lists. Add vx-share to default list of include
4340 directories. Add new files to src and target lists: mem-break,
4341 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4342 ${srcdir} versions of munch and createtags are used.
4344 * valops.c (find_function_addr): Split out of call_function.
4345 (call_function_by_hand): Rename call_function; this function
4346 calls functions in the target by laboriously patching the target
4347 word-by-word with the right stack, args, regs, etc.
4350 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4352 Handle AMD 29000 a bit better.
4354 * remote-eb.c (readchar): Mask received char log to make it readable.
4355 (remote_start): Pass arguments down to executing program.
4356 Make startaddr unsigned.
4357 infrun.c (start_inferior): Accept args, pass them to
4359 infcmd.c (run_command): Pass args down to start_inferior.
4361 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4362 the target object file format.
4363 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4365 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4366 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4368 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4370 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4371 * TODO: We did a few things, we have more to do though.
4373 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4374 * inflow.c (inferior_died): Clear deferred stores.
4376 * Debug problems with dummy frames and calls to the inferior.
4377 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4378 * sparc-tdep.c (do_restore_insn): Simplify.
4379 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4380 (sparc_push_dummy_frame): Simplify and fix what we push.
4381 (sparc_pop_frame): Slightly more hair here, deciding whether
4382 we are restoring a saved PC or returning to a return address in %i7.
4383 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4385 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4386 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4387 * obstack.h (chunkfun): ditto.
4388 * defs.h (xmalloc, xrealloc): ditto
4390 * utils.c (quit): Grab the terminal from the child if necessary.
4392 * inflow.c (term_status_command): Rename to term_info, change
4395 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4396 (is_delayed_branch): Speed up.
4397 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4398 Still missing some float ops, and needs testing.
4400 * Support for input and output radixes other than base 10
4401 * defs.h (input_radix, output_radix): Declare.
4402 * expread.y (yyparse, parse_number): Handle changes of input
4403 radix, and ambiguous names-or-numbers in radixes >10.
4404 * printcmd.c (print_scalar_formatted): Print formatted hex
4405 numbers in varying column widths.
4406 * valprint.c (val_print): Use output_format to print scalar ints.
4407 (set_input_radix, set_output_radix, set_radix): Create.
4408 (set_output_radix): Set output_format from output_radix.
4409 (_initialize_valprint): add `set radix' but leave the others off.
4411 * main.c (execute_command): Let stupid questions be turned off.
4412 (_initialize_main): Handle "set stupidity", etc.
4414 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4415 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4417 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4419 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4420 bfd stuff is still screwed up, but with some manual work, it
4423 * breakpoint.c (bpstat_do_actions): Start over if a command
4424 proceeds the inferior, since the inferior will have stopped and
4425 will need to have its new stop-actions taken care of.
4427 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4428 compiler fits, simplify it.
4430 * gdb.texinfo (directory command): Doc new dir command.
4431 source.c (directory_command): "dir" now puts things on the front
4432 of the path, moves dups up front, and handles multiple names
4433 on the command line, inserting each one in order. It also
4434 blows away cached line and full_filename info.
4436 * stack.c (backtrace_command): Skip "more stack frames follow"
4439 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4440 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4441 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4442 The only odd one was Gould NP1, which had defined vprintf to
4445 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4446 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4447 variable, inspect_it.
4448 valprint.c (print_string, val_print): Use the global inspect_it
4449 to indicate whether to print in Epoch style or normal style.
4451 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4453 * printcmd.c (call_command): add an alias for the "print" command
4454 which runs expressions and doesn't print the result if void.
4455 (print_command_1): implement it.
4457 * command.c: Remove #if 0'd code. Initialize all the fields
4458 in add_cmd (). Rename do_nothing_command to
4459 not_just_help_class_command, and make it externally visible.
4460 command.h: add user_commands to struct.
4461 * main.c (define_command): Don't overload c->function with a char
4462 string as well as a function pointer.
4464 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4465 calling convention of value_struct_elt () that got dropped in
4468 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4469 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4471 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4473 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4474 until a good time (e.g. when we are about to run the child),
4475 saving ptrace calls.
4476 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4477 * tm-sparc.h: define DO_DEFERRED_STORES.
4479 * sparc-xdep.c (store_inferior_registers): when storing float
4480 registers, don't store stack regs too. When storing the SP,
4481 however, DO store the stack regs too. This fixes a bug in which
4482 the dummy frame is not recognized when a call_function finishes,
4483 because its frame pointer (in the stack regs) was never
4485 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4486 even though we don't know how to read them from an inferior.
4487 valops.c (call_function): Comment about storing SP.
4489 * infrun.c (save_inferior_status): Save away the original bpstat
4490 chain so it can be restored later. Install the copied version for
4491 use by whoever saved the status. It will be blow away by
4492 restore_inferior_status, and the original chain restored. This is
4493 important for people who have pointers into the original.
4495 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4496 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4497 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4500 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4502 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4503 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4504 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4506 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4508 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4509 Store the baseclasses in a type struct starting from array element
4510 0 rather than from the unusual array element 1.
4512 dbxread.c: the above.
4513 (virtual_context): Add
4514 Read new debug information about which virtual function table
4515 a virtual function is from, and store it in fn_field.fcontext.
4517 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4518 TYPE_FN_FIELD_STATIC_P.
4520 symtab.c: the above.
4521 valops.c: the above. Handle pointer casts of object *'s.
4522 (search_struct_method): Add.
4523 (value_struct_elt): First arg is now a pointer to a value, and is
4526 valprint.c: the above.
4527 values.c (value_virtual_fn_field): Add type arg. Handle
4528 offsetting to the proper object when calling virtual fns.
4530 (baseclass_addr): Add valuep arg.
4532 * README: Document the current state of BFD config (missing).
4533 * TODO, ChangeLog, Makefile.dist: Roll version.
4534 * WHATS.NEW: Add summary of changes since 3.5.
4536 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4538 * dbxread.c (read_struct_type): Clear bit vectors whenever
4540 symtab.c (B_CLRALL): define.
4542 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4543 using == rather than =. Huh... This fixes the dreaded problem
4544 wherein builtin_type_int becomes TYPE_CODE_FLT.
4546 * core.c (info_files): Show the inferior pid.
4548 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4549 already knows how to look in the source directory.
4551 * Remove psymtab hair from many places. Remove duplicated code
4552 for searching symbol tables. Hide psymtabs from most places.
4553 Make it fast to get from a psymtab to its symtab.
4555 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4556 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4557 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4558 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4559 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4560 new symtab completely. New psymtabs get symtab pointer
4561 initialized to zero. Remove MI warning printf.
4562 symtab.h: Comments. Add psymtab to symtab pointer.
4563 (PSYMTAB_TO_SYMTAB): New macro.
4564 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4565 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4567 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4569 (print_frame_info): Avoid special-casing symbols that have not yet
4572 * source.c (open_source_file): Quick path if we have already
4573 located the source file by its full name.
4575 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4576 find_pc_psymtab. When a name is found in the misc function
4577 vector, search the symbol table for its mangled name, not the
4578 name that the user typed.
4580 * bfd.h: Fix missing comment terminators, make #endifs match.
4582 * valarith.c (value_less): Handle unsigned int comparisons.
4583 Add FIXME about pointer compares, which assume host and target
4584 pointers are the same.
4586 * command.c (do_nothing_command): lint
4587 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4588 fix comments on debug symbol format for visibility. Actually set
4589 visibility of symbols.
4590 main.c (echo_command): lint; use <readline/history.h>.
4591 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4592 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4593 pointing past end of allocated memory; saber complains.
4594 obstack.h: Declare the external functions that we use.
4595 valarith.h: use <string.h>
4596 solib.c (solib_add): lint.
4598 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4600 * main.c (initialize_main): Default info_verbose to off, now that
4601 symbol reading is fast.
4602 (quit_command): Avoid clobbering exec_bfd while quitting.
4604 * Initial BFD (binary file diddling library) merger:
4605 coffread.c: Change AOUTHDR to struct exe_hdr.
4607 core.c: initialize initialized data at compile time.
4608 (core_file_command): Move from coredep.c, convert to bfd.
4609 (xfer_core_file): Convert to bfd.
4610 exec.c (exec_file_command): use bfd routines.
4612 mips-tdep.c: Remove exec_file_command and friends.
4615 * coredep.c: (fetch_core_registers) Convert core_file_command to
4616 fetch_core_registers.
4617 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4619 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4620 (my_bfd_read): More bogosity, which I don't think we call.
4621 (program_name): Remove this atrocity asap!
4623 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4626 values.c: allocate_repeat_value was not clearing the
4627 optimized_out field.
4628 (value_static_field): minor stylistic fix (wrong macro was used).
4629 valops.c (value_struct_elt_for_address): didn't work for C++
4632 * signame.c (_initialize_signame): Initialize signal names once.
4634 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4635 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4636 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4638 * remote-eb.c: Support user-settable baud rates on the serial port.
4640 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4642 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4644 * tconfig/sun3os4: Remove warning about native assembler,
4645 since it also occurs in the xconfig file.
4647 * findvar.c (registers): Allocate some slop after `registers'
4648 to prevent stray accesses from trashing the next variable.
4650 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4651 on the sun-3, by changing the #ifdef from `sun3' (which is not
4652 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4653 vars, which happened to follow `registers' in the executable.
4655 * readline/history.c (history_search): Heed gcc-2's advice
4656 and parenthesize && inside ||).
4658 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4659 tm-29k.c: Insert FSF copyright headers.
4661 * remote-eb.c: Better comments.
4663 * Makefile.dist: Update to 3.91.6.
4664 * TODO: note PREPARE_TO_STORE problem.
4666 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4668 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4670 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4672 * infrun.c (wait_for_inferior, at end): Don't set up
4673 prev_* if the inferior no longer exists.
4675 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4676 CANNOT_EXECUTE_STACK.
4677 valops.c (call_function): Use it.
4679 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4681 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4682 infrun.c (wait_for_inferior, 2 places): Use it.
4684 * values.c (value_being_returned): Only use
4685 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4687 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4688 right thing for remote-eb.c.
4690 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4691 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4693 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4694 (FRAME_FIND_SAVED_REGS).
4696 * findvar.c ({fetch,store}_registers): Check for
4697 REMOTE_{FETCH_STORE}_REGISTER macro.
4699 * findvar.c (get_saved_register): Add argument lval and
4700 change meaning of argument addr.
4701 findvar.c: Change calls to get_saved_register to reflect
4702 new calling convention.
4703 valops.c (value_assign): Use get_saved_register instead of
4704 find_saved_register.
4706 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4708 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4709 an (uninitialized) pointer to one. Use "&" when passing it
4712 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4714 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4717 * coffread.c (symbol_file_command): Put semicolon after
4719 Put safe_to_init_tdesc_context in #if defined (TDESC).
4720 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4721 coffread.c: #include <sys/stat.h>.
4722 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4723 Add missing ')' in check for "lc%" and friends. Remove
4725 Declare read_one_sym() at top of file.
4726 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4727 MC68WRMAGIC can have the same value without causing a duplicate
4730 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4732 * Allow a Makefile to be built without building the
4733 tm and xm file links that screw up builds in subdirectories.
4734 This is done with `config.gdb none', then you can do things
4735 like `make gdb.tar.Z'.
4736 * tconfig/none: Config file for no target system
4737 * xconfig/none: Config file for no host system
4738 * config.gdb: If no TM or XM files are called out by the
4739 host or target file, don't make links for them.
4741 * cplus-dem.c: Add documentation.
4743 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4744 simple error, so the user's gdb doesn't crash due to some object
4745 file problem (e.g. somebody is rebuilding the file out from under
4748 * printcmd.c (print_address_symbolic): demangle the symbol.
4750 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4751 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4752 (alldeps.mak): sort and uniq all results from this; duplicates
4753 hose gdb.tar.Z link building. Remove RCS files from
4754 tconfig and xconfig. Add config files for sun386. Add
4755 a few odd files to OTHERS and HFILES.
4757 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4759 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4760 Roll version number to 3.91.5. Make lint work in bindir.
4762 * README: Document cross-debugging and new file structure.
4764 * blockframe.c: Lint. Include "value.h" to declare read_register.
4765 (find_pc_partial_function): remove duplicate line.
4767 * command.h: Lint. Declare error_no_arg and dont_repeat.
4769 * tm-news.h: Remove inadvertently duplicated stuff.
4771 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4772 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4774 * config.gdb: Allow `config.gdb host target' form. Clean
4775 up previous change that printed bogus messages when you just said
4778 * core.c: #include "command.h" for lint.
4781 * main.c: Remove some casts of enums. Lint.
4788 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4790 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4791 read it from memory. This will allow us to save ptrace calls
4792 eventually. Changed caller single_step too.
4794 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4795 that we aren't going to use, saving many ptrace calls, especially
4796 when watchpointing or single stepping. Use some #define's for
4798 (store_inferior_registers): Ditto.
4799 (core_file_command): Use some #define's for constants.
4801 * tm-sparc.h: Add #define's for some register numbers, so we
4802 can eliminate the use of random constants in sparc-xdep.c.
4804 * stack.c (frame_command, print_frame_info, up_command,
4805 down_command) Remove frame_changed, since it
4806 causes a bug and doesn't seem to do anything useful. In some
4807 places it was used as a flag, in others as a stack level (?).
4809 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4810 default is to use the portable (vprintf) version rather than the
4812 * xm-news.h (MISSING_VPRINTF): Add.
4814 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4816 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4818 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4819 about linking debugged programs -Bstatic in the sun?os4 config
4820 files in tconfig and xconfig subdirectories.
4822 * main.c (main): Remove unreached exit(0) now that we exit
4825 * Create TODO file for online bug list. There are too many
4826 "little" bugs to keep track of on paper.
4828 * Change Projects file to refer to bug-gdb@cygnus.com
4829 rather than kingdon@ai.
4831 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4833 * Makefile.dist (VERSION): 3.91.4 now.
4835 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4836 (condense_misc_bunches): Add sanity check that misc_count is
4837 the same as the number of symbols in the bunch.
4839 * coffread.c: rename init_misc_bunches. Pass an argument
4840 to condense_misc_bunches (a zero).
4842 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4843 every time we are called; don't rely on our caller to do it.
4844 (add_file): Remove call to init_misc_bunches.
4846 * mipsread.c: Only warn, don't error, if unknown symbol types.
4847 This keeps an old gdb from falling on its face if it sees newly
4848 extended symbol info. Rename init_misc_bunches.
4850 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4852 * Merge in changes from Per Bothner for DECstations and other
4853 MIPS stuff. The rest is Bothner speaking:
4855 The next message is a merger of Alessando Forin's mips port with
4856 mine. I've tried to use my good if biased judgment to get
4857 the best of both. It *does* need testing.
4859 Some of the changes are general, *not* mips-specific.
4862 Didn't believe in little-endian bit order.
4863 There are still inconsistencies about whether flags
4864 like BITS_BIG_ENDIAN are integer (#if ...) or
4865 boolean (#ifdef ...). I tried to paper over them.
4867 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4868 Moved some misc_function code that was common to
4869 {dbx,coff,mips}read.c to symtab.c.
4870 In the process, I think I cleaned things up a bit.
4871 At the same time, moved obsavestring and obconcat to symtab.c.
4874 Removed obsolete condense_addl_misc_bunches (use
4875 condense_misc_bunches(1) instead).
4878 Needed to include <sys/dir>, at least on DECstations.
4880 valops.c, mips-tdep.c, tm-mips.h:
4881 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4882 conventions (when STACK_ALIGN is insufficient).
4883 Needed on mips, where doubles need 8-byte alignment,
4884 but ints only need 4.
4887 Removed cruft that was not being used.
4888 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4891 Print $ before register-names (I think that makes things a little
4893 Never print two instructions, even if one delays.
4894 Removed hex-disassemble set_cmd. (This is not mips-specific,
4895 so I think the argument is whether it is generally worthwhile or not.
4896 I'm inclined to think not, given how easy it is to
4897 convert between radixes in gdb.)
4900 This is basically Alessando's code.
4901 It doesn't use obstacks; I changed it to use obstacks
4902 in a few minor places where using malloc causes a
4903 memory leak. (Probably, more places could/should be changed.)
4904 I added record_misc_function where it was missing.
4905 In symbol_file_command and add_file_command, I tried
4906 to make the code consistent with more recent versions.
4907 Minor sylistic changes in parse_procedure.
4908 Make a .gdbinfo. psuedo-symbol point back to the real
4909 procedure symbol (using the isym field).
4912 This is basically from my port, but with a lot of details
4913 and a number of routines merged in from Alessando's version.
4914 I basically used my code "raw" backtrace (use heuristics
4915 from the actual code, rather than symbol table info) - though
4916 the idea is Alessandro's. I feel my code is a little cleaner
4917 here, particularly in being a little more flexible, such as being
4918 able to handle gcc-produced code (which it now can).
4919 It also doesn't do frame caching (which is not useful
4920 more recent gdb versions).
4921 I also used my code for push_/pop_dummy, more or less.
4922 I tried to incorporate AF's code for testing sigtramp
4923 while backtracing; I probably got it wrong.
4924 Added mips_print_register, which tries to scrunch as much
4925 information as possible on a screen...
4926 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4927 under mips-pinsn.c), I don't see anything mips-specific here,
4928 and I don't see it being all that useful anyway.
4931 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4932 Use more register names (rather than hard-cases numbers).
4934 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4936 * Hack up 3.90.11 changes:
4938 * Makefile.dist (depend): parameterize $(GCC).
4939 Add solib.c and solib.o.
4940 (readline): Fix vpath for both absolute or relative SRCDIR.
4942 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4943 Also, let the part I didn't understand at least compile so
4944 I can test the rest. FIXME.
4946 * dbxread.c: Fix thinko using strcmp.
4947 (init_psymbol_list): declare static.
4948 (partial_symbol_file_open): Comment cleanups better, avoid
4949 cleaning up the string table since the caller will do that.
4950 Move the stat for mod time into symbol_file_command, temporarily.
4951 (There should be a mod time for each symbol file, eventually,
4952 to control its rereading. FIXME.)
4954 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4955 SunOS, which gives error for shared libs otherwise. (From
4956 Schaefer, probably FIXME needs work for portability.)
4958 * solib.c: Move #include "param.h" to work.
4959 Lowercase all the Uppercase Letters In the Messages.
4960 (find_solib): Clean up inferior_so_name for debug printouts.
4961 Allow no argument, to mean all shared libraries.
4963 * symmisc.c: include param.h to get CLEAR_SOLIB.
4965 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4967 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4968 to 3.90.11. ChangeLog entries below are from this.
4970 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)

4976 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4980 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4982 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4984 * sparc-opcode.h Added single-operand version of rett.
4986 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4988 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4989 Put parens around gcc_p in expansion.
4991 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4993 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4995 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4997 * Changes for Sun shared libraries:
4998 blockframe.c (find_pc_partial_function): If a non-text symbol
4999 is found, set *address = pc - FUNCTION_START_OFFSET.
5000 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
5001 Disable breakpoints instead of giving an error.
5002 source.c (select_source_symtab): Initialize cs_pst.
5003 symmisc.c: Call CLEAR_SOLIB if defined.
5004 symtab.h: Make text{low,high} CORE_ADDR not int.
5005 (psymtab): New field addr.
5007 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
5008 (record_misc_function): Give correct type for N_DATA symbols.
5009 (condense_misc_bunches): do "misc_function_count = j" regardless
5011 Take code which is shared between symbol_file_command and
5012 add_file_command and put it into partial_symbol_file_{open,read}.
5013 Split add_file_command into add_file_command and add_file.
5014 Make psymtab_to_symtab read in the string table if the file
5016 Two new parameters to read_dbx_symtab and start_psymtab.
5017 tm-sunos.h: New file.
5019 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5021 * infcmd.c: Change cont_command to continue_command and "cont"
5024 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5026 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5028 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5030 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5031 size 1,2,4,8 rather than size < 8.
5033 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5034 as necessary, not just once.
5036 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5038 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5040 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5042 * tm-news.h: Add CALL_DUMMY_*.
5044 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5046 * config.gdb: In list_host, list_target, use ${i}, not $i.
5048 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5050 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5052 * sparc-opcode.h: Change all store floating-point state register
5053 instructions to have the right match & lose fields.
5055 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5057 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5059 config.gdb: If srcdir != ., create readline directory and
5060 copy a makefile into it.
5062 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5063 consistency with POSIX.
5065 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5066 when we exit its exp_valid_block.
5068 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5070 * Makefile.dist: Bump version to 3.91.3.
5072 * Clean up handling of breakpoint commands (somewhat).
5073 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5075 inferior.h: Add breakpoint_proceeded to inferior status struct
5076 and globals; save it and restore it.
5077 (clear_breakpoint_commands): Cleanup, remove old #define.
5079 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5080 (save_inferior_status, restore_inferior_status): handle it also.
5081 (proceed): Remove earlier code that set breakpoint_proceeded.
5082 It is now set only in clear_proceed_status.
5083 (clear_proceed_status): Cleanup, use bpstat_clear rather
5084 than clear_breakpoint_commands. No callers need the stop_bpstat
5085 between clear_proceed_status and proceed.
5087 infcmd.c: Add breakpoint_proceeded definition and comment.
5088 (cont_command, jump_command, signal_command): Move call to
5089 clear_proceed_status right next to call to proceed.
5091 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5092 caller's argument while running down the chain of breakpoints.
5093 Use new variable "breakpoint_proceeded" to determine when
5094 a command that it executes moves the inferior past the
5096 (bpstat_clear): Handle NULL argument.
5097 (bpstat_clear_actions): Avoid useless call to
5098 breakpoint_auto_delete.
5099 (delete_breakpoint): Clean up bpstat's that are pointing to
5100 the deleted breakpoint from the stop_bpstat chain.
5101 (breakpoint_auto_delete): Simplify.
5103 * Clean up handling of EOF, error on stdin, etc. This was
5104 prompted by a network problem that caused gdb to go into an
5105 infinite loop filling up its malloc'd memory.
5107 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5108 not clear_breakpoints_commands, which is now gone.
5109 (main): If command_loop returns (e.g. from EOF on stdin), do
5110 a quit_command (looping back to command_loop if quit_command
5111 doesn't really quit).
5112 (command_loop): check result from command_line_input and
5113 exit if it returns NULL, rather than passing the NULL to
5115 (gdb_readline): Free malloc'd result space before returning
5118 * utils.c (query): Handle C-d to mean "yes", just as if the
5119 input was not a terminal. Also avoid infinite loop if EOF
5120 occurs in mid-input-line before newline. This allows
5121 query to be used at EOF on stdin with reasonable results.
5123 * infrun.c (proceed): Set breakpoint_proceeded.
5125 * values.c (value_as_long): Avoid infinite recursion for enums.
5126 (_initialize_values): Fix typo in help msg (kingdon).
5128 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5129 RL_LIB for linking. This allows -lreadline for linking
5130 and nothing for dependencies, once readline is a real library.
5132 * config.gdb: Jim Kingdon: give useful error message if the
5133 host or target type is not recognized.
5135 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5136 it just defines it. Dumb, but deal with it.
5138 * Jim Kingdon suggests:
5139 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5141 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5143 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5145 * Clean up Bothner's changes.
5147 * blockframe.c (clear_pc_function_cache): New function.
5148 * blockframe.c: remake cache_pc_function_* static.
5149 * dbxread.c (symbol_file_command): remove references to
5150 cache_pc_function_* variables.
5151 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5152 * printcmd.c: Avoid kludging a global variable (addressprint)
5153 to avoid printing the address of a string twice. Instead,
5154 pass the format letter 's' down low enough that it can be seen
5155 to avoid this problem.
5156 (print_formatted): Pass format arg to value_print.
5157 (restore_addressprint): Remove function.
5158 (do_examine): Avoid hacking addressprint, cleanups and such.
5159 (print_frame_args): Add a comment to a Bothner change.
5160 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5161 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5162 to wipe out the values cached in blockframe.c.
5163 * symtab.c (find_method): Add comment saying how big you must
5164 allocate to be "big enough". Per being terse again.
5165 * valprint.c (val_print): Handle format letter "s" to print
5166 strings without addresses. Add comment to vtbl printing code
5167 which casts with wild abandon. Rearrange reference-printing
5169 @0xaddr: value (print w/addressprint)
5170 value (print w/~addressprint)
5171 @0xaddr (parameter lists w/addressprint)
5172 or nothing (parameter lists w/o addressprint)
5174 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5176 * Merge more changes from Per Bothner:
5178 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5179 annoying) that I tried to improve it. Here are my suggestions.
5181 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5184 Do automatic de-reference when taking the address of a reference.
5186 Don't deref_ref when printing parameter lists.
5188 More attempts at treating refernences properly.
5190 In val_print, if deref_ref==0, don't print dangling " = ".
5192 Add COERCE_REF macro, which de-references an REF.
5194 * Merge changes from Per Bothner:
5196 * Fixed (Sony news)-specific configuration problems.
5197 * Fixed other problems with using vanilla pcc and libc (enum problems;
5198 assumption that vsprintf exists).
5199 * Some major speed-ups (finc_pc_partial_function now caches a match;
5200 parsing avoids duplicate symbol_lookup calls).
5201 * Changed handling of baseclasses (no longer use baseclasses field
5202 of struct type, use the first n_baseclasses fields instead).
5203 * Various minor changes/fixes, most C++-related.
5206 Cache the most previous match from find_pc_partial_function.
5207 (Save both low and high ends of matching function's pc range.)
5208 This speeds up the loop of infrun.c:wait_for_inferior quite
5209 a bit, and makes step/next commands much zippier.
5211 Added an enum->int cast (otherwise, some compilers barf).
5213 No longer set baseclass offset to 0, since multiple
5214 inheritance now mostly works.
5215 Added a number of casts, to shut up compiler warnings
5216 (after stabs where made enums, not ints).
5217 When discarding a symbol table (in symbol_file_command),
5218 must clear the cache introduced in blockframe.c.
5219 Don't convert $vtbl_ptr_type to vtbl any more.
5220 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5221 Mask off sign bit emitted by g++ for virtual table offset.
5222 Set voffset to -1 (not 1) for static member functions.
5224 Changed parsing/lexing of names to avoid doing symbol lookup twice
5225 (once when lexing to determine symbol class, once for real).
5226 Now only call symbol_lookup once. Fields of 'this' win especially big.
5228 Subpress printing addr twice in the case of 'x/s addr'.
5230 lookup_basetype_type is no longer used.
5231 Add find_methods as recursive helper function to decode_line_1.
5232 This allows multiple inheritance to work.
5233 Also, once one or more matches has been found, do not look in
5234 base-classes. (Baseclass methods would be overridden, anyway.)
5236 Removed baseclasses array in struct type.
5237 Instead of using baseclasses[i], use fields[i-1].
5238 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5239 Changed sign convention of voffset (previous was inconsistent).
5241 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5243 Used to assume existence of vsprintf. Re-written to not need it
5244 if HAVE_VPRINTF is undefined.
5246 typecmp was too pessimistic. Made it less so.
5248 Don't print space after address.
5249 If vtable points to a misc symbol (with 0 offset), print it,
5250 since that indicates the actual class of the object.
5251 Changed ype_print_derivation_info to use new inheritance
5252 scheme (without baseclasses vector).
5254 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5255 Also, changes needed because TYPE_BASECLASSES were removed.
5257 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5259 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5262 If there is no path set, and the symbols don't indicate what directory
5263 a file was compiled in, look in the current directory. But either
5264 a path or a known compilation directory will prevent this.
5267 Three independent bug fixes:
5268 * Remove the #if 0 block that breaks some stuff.
5269 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5270 adapt gdb to either SunOS 4.0.* or 4.1.
5271 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5274 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5277 (type_print) Demangle the name being printed.
5278 (type_print_base) Handle botched demangling without coredump (tiemann).
5281 (check_stub_method): Document routine.
5282 (tiemann) fix bug for no-arg functions
5283 Avoid clobbering beyond end of malloc'd storage.
5284 Terminate the argument list properly.
5286 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5288 * Changes merged by John Gilmore:
5291 In breakpoint_1, use new print_address_symbolic instead
5292 of find_pc_partial_function. (This forces use of assembler-level
5293 addresses, and avoids misleading non-mangled source-level names.)
5295 Generalize ansi argument such that -1 means skip arglist totally.
5296 Removed global variable print_ansi_qualifiers (which made
5297 code non-reentrant), in favor of extra explicit arguments
5298 to internal routines.
5300 Add new helper function print_address_symbolic.
5301 Use find_pc_misc_function instead of find_pc_partial_function
5302 (since we want assembler-level symbols here).
5304 Print unknown function as just "f (...)", not "f (...) (...)".
5305 Use new fputs_demangled explicitly.
5307 Fixed a typing violation (problem: value.h cannot be imported
5308 without renaming many variable in this file).
5309 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5310 decode_line_1: Moved forward some never-reached code.
5311 Made decode_line_2 skip function prologues correctly.
5313 fputs_filtered should not demangle by default.
5314 Add new fputs_demangled to demangle on demand..
5316 Change value_struct_elt to use value_primitive_field (using recursive
5317 utility function search_struct_field). This allows foo.bar to work
5318 for multiple inheritance (so far only for data fields).
5319 Change check_field in the same way (recursive helper function
5320 to support multiple inheritance).
5321 (Note: there are more of these problems that I haven't fixed.
5322 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5323 value_of_this: 'this' symbol name is now just "this", note "$this".
5325 Don't print static members.
5326 Avoid printing "members of <type>" if there are none.
5327 Simplified type_print_derivation_info by merging duplicate code.
5328 Remove useless blank lines in type_print_base (ptype command).
5330 Added declaration of new routine value_primitive_field.
5332 Added value_primitive_field which is generalized version of
5333 value_field that can handle multiple inheritance (non-zero offsets etc).
5334 Re-implemented value_field to call value_primitive_field.
5336 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5338 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5339 delete the whole environment. Karl Berry reported the bug.
5340 * source.c - fix openp to avoid //'s in filenames, which
5341 trigger an Emacs bug causing it to not be able to find files
5342 when running gdb in a window.
5343 * dbxread.c - zap the #if 0 that botches the add-file code.
5344 It seems to work a lot better without all the code commented out.
5346 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5348 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5351 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5353 * Makefile - added a ${CFLAGS} to a couple of entries,
5354 added remote-sa.sparc.c
5355 * added remote.sa-sparc.c, a modification of remote.c
5356 which conducts a dialog directly with the SparcStation prom.
5357 * breakpoint.c, infrun.c, sparcdep.c added
5358 remote_insert_breakpoint(), and remote_remove_breakpoint()
5359 to breakpoint.c instead of directly writing breakpoint instructions.
5360 * sparcdep.c on remote_debugging,there is no need
5361 to remove signle step breakpoint instructions.
5362 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5364 * printcmd.c - epoch interface sends lisp expressions to open up
5365 epoch windows on inspection.
5366 * valprint.c - added arrayprint, and addressprint and made adding
5367 format controls easier
5368 * wait.h added a couple of undef's because we were getting
5369 complaints about WSTOPSIG and WTERMSIG begin redefined.
5372 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5374 * symtab.c (decode_line_1): Add support for handling method stubs
5375 in the type information.
5377 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5379 * values.c (baseclass_addr): Run loop from INDEX+1 to
5380 N_BASECLASSES; otherwise, we can still get into a loop.
5381 @@ This should be restructured to use a cleaner search strategy.
5383 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5385 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5386 abbreviation "Tt" for tags which have the same name as their
5389 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5391 * symtab.c (list_symbols): add ability to set breakpoints on all
5392 the functions which match a particular regular expression.
5394 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5396 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5397 should print ANSI qualifiers (such as `const' and `volatile').
5398 All callers changed to call with ANSI == 1, except from
5399 `check_method_stub', which uses old-style syntax.
5401 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5402 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5404 * values.c (check_stub_method): New function.
5406 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5408 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5409 * valprint (type_print_base): Ditto.
5411 * symtab.c (gdb_mangle_typename): New function.
5413 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5415 * breakpoint.c (catch_command): New function. Provides a
5416 mechanism to set breakpoints based on catch clauses.
5417 (disable_catch): Similar, but disables breakpoints on catch
5419 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5421 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5423 * blockframe.c (blockvector_for_pc): New function.
5424 * blockframe.c (block_for_pc): Changed to call
5425 `blockvector_for_pc' and get the block itself.
5427 * stack.c (catch_info): New function. Prints info about
5428 exceptions which can be caught in the current frame.
5429 * stack.c (print_frame_label_vars): New function. Similar to
5430 `print_frame_local_vars'.
5431 * stack.c (print_block_frame_labels): Prints out labels that are
5432 defined in this frame. These labels are exceptions that can be
5435 * dbxread.c: Updated to handle N_CATCH symtab types.
5437 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5439 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5440 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5441 when printing the type.
5443 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5445 * valprint.c (val_print): Use `baseclass_addr' to access the
5446 baseclasses pointed to via the derived class object at VALADDR.
5448 * values.c (baseclass_addr): New function. Casts derived pointers
5449 to baseclass pointers taking virtual baseclasses and multiple
5450 inheritance into account.
5452 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5456 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5458 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5459 exp_valid_block field correctly.
5461 * infrun.c (wait_for_inferior): When checking "don't even think
5462 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5463 also check step_resume_breakpoint.
5464 Insert breakpoints and continue (not step) if
5465 step_resume_break_address != NULL, even if another_trap.
5466 If trap_expected and we enter sigtramp, then set up a
5468 If trap_expected is set when we hit the step_resume_break,
5470 When calling resume and trap_expected says tell resume to step
5471 (2 places), also check step_resume_break_address.
5473 * infrun.c (wait_for_inferior): Don't set
5474 prev_{pc,sp,func_{start,name}} before calling wait ().
5475 Do set them after exiting loop.
5476 Move their declarations outside functions.
5477 (start_inferior): Initialize them.
5479 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5481 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5482 Restore old code which distinguishes between trap_expected and
