1 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
3 * language.c (_initialize_language): Fix type check and range
4 check documentation strings.
5 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
6 language.c can use it. (Though language.c should really not be
7 handling warnings/errors the way it does, FIXME.)
8 * symtab.c (lookup_primitive_type): const lint.
10 Bugfix from Peter Schauer:
11 * source.c (lines_to_list): Make signed, to avoid comparison
12 going unsigned and complaining that -3 is too high for 21 lines.
13 * stack.c (lines_to_list): Ditto.
15 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
17 * Makefile.in (HFILES): Add minimon.h.
18 (VERSION): Roll version number to 4.0.95.
19 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
20 New rules for building distributions. Normal distribution
21 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
22 one level up from here; it calls make-proto-gdb.dir to build a
23 directory `proto-gdb' which is an image of the release. The old
24 `gdb.tar.Z' rule still works too.
25 * config.sub, configure: Roll in latest from ..
27 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
29 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
30 new-target, and new-config chapters; fix minor typos; come closer
31 to usual GNU markup conventions for @file @samp @code @var.
33 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
35 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
36 * mipsread.c (parse_partial_symbols): Enter the name of all
37 structs/unions... into the psymtab so we can access them if the
38 symtab is not read in.
39 * mips-tdep.c: Remove some unneded (?) #includes.
40 * xconfig/dec3100: Add HAVE_STRSTR.
42 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
44 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
45 * c-exp.y, m2-exp.y: Lint.
46 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.
47 * valprint.c (val_print_fields): Check for stub type.
48 * mipsread.c (_initialize_mipsread): Avoid using
49 builtin_type_void at initialize time.
50 (mipscoff_symfile_read): use it now.
52 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
54 Merge multiple-language support, and partial Modula-2 support,
55 from Andrew Beers <beers@cs.buffalo.edu>.
57 * i387-tdep.c: New file, consolidates most 80387 support,
58 and eliminates host dependency on double<->extended conversions.
59 * i386-xdep.c, symm-xdep.c: Remove most 387 support.

76 * coffread.c (end_symtab): Use allocate_symtab.
77 (process_coff_symbol): #if 0'd for functions and params as above.
78 (read_enum_type): Recognize Modula-2 BOOLEAN.
79 * symtab.c (add_param_to_type): #if 0'd function to add a

152 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
154 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
155 entries are enclosed herein:
157 Mon Jun 3 17:05:45 EDT 1991
159 m2-exp.y Created. Tested outside of GDB for a few days. Proper
160 operators were added, C specific operators and tokens
161 removed. yylex() revamped to some extent. Still things
162 missing from the grammar, such as sets.
163 Tested for two weeks in GDB v3.5.
165 Tue Jun 11 17:23:48 EDT 1991
167 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
168 so they are built-in. Sort of a hack.
170 Fri Jun 14 12:53:51 EDT 1991
172 m2-exp.y Added range checking for numeric constants. Any numeric
173 constant is assumed to be of builtin type INTEGER unless:
174 (1) it is octal or hexadecimal, in which case it is a
175 CARDINAL; (2) it is too big to fit into an INTEGER, in
176 which case it is a CARDINAL.
177 eval.c Added simple range checking for +, -, and * on integers.
178 Doesn't work very well for *, since 6 * 1,000,000,000 =
179 1,705,032,704, which fails the simple test of result >=
180 first_operand, no matter in what order the operands are.
182 Tue Jun 18 14:11:30 EDT 1991
184 Broke the parser into parts, one containing the C grammar and the other
185 containing code to be shared by all of the grammars.
187 The following files no longer exist:
192 The following files were added:
194 c-exp.y (The C grammar)
195 m2-exp.y (The Modula-2 grammar)
196 parser-code.c (Code that is shared by the above grammar)
200 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
201 now necessary to use the Bison compiler compiler, since it
202 will generate function/variable prefixes other than yy.
204 Tue Jun 18 16:47:49 EDT 1991
206 symtab.[ch] Added the external variable working_lang, than holds the
207 value of the current working language.
208 Added the ennumerated type language_mode, with the values
209 language_auto and language_manual, the former meaning that
210 GDB sets working_lang as needed, and the latter meaning
211 that the value of working_lang is totally under user
213 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
214 REAL, BOOLEAN and CHAR. Also added the type codes
215 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
216 utils.c Added set_language_command and show_language_command to
217 implement the GDB support commands "set language" and
219 expression.h A number of identifiers were added to the type exp_opcode
220 to facilitate Modula-2 builtin functions, integer
221 division, and array indexing.
223 Wed Jun 19 13:25:58 EDT 1991
225 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
226 if the language specified by working_lang requires the use
227 of strict typing of expressions. Eventually, even this
228 will be able to be changed by the user.
229 Added the macro RANGE_CHECK, which evaluates to non-zero
230 if the language specified by working_lang requires the
231 checking of a value against the domain of its type.
232 Eventually, even this will be able to be changed by the
234 language.[ch] Predicates involving types (simple_type, ordered_type,
235 same_type, integral_type, numeric_type, character_type,
236 boolean_type, float_type) are added. These predicates are
237 based on the current value of working_lang, and are handy
240 Wed Jun 19 15:39:34 EDT 1991
242 eval.c Added the function type_array_rank which computes the rank
244 valarith.c Added the funtion value_bool, which when given a integer
245 value.h value (ie. struct value *) as an argument, it returns a
246 boolean value (ie. struct value *) true if that integer
247 is non-zero, and a boolean value false otherwise.
248 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
249 will print out properly.
251 Wed Jun 19 16:36:34 EDT 1991
253 valops.c Added the function value_capitalize, which returns it
254 value.h argument capitalized if its argument is a lowercase
255 letter, or the argument unchanged if its argument is not a
257 valarith.c Added the function range_check_p, which returns non-zero
258 value.h if its value argument is between the integral bounds upper
260 Added the function range_check_enum_p, which makes sure
261 that its value argument is a valid member of the domain of
263 Added the function range_check_range_p, which makes sure
264 its value argument lies between the upper and lower bounds
265 of its type argument, which must be a ranged type.
266 Added the function check_array_index, which range and type
267 checks an index of an array.
268 Added the function value_multi_subscript, which computes
269 array[idx1,idx2...idxN], given a value array and an array
270 of values representing indicies.
271 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
272 unpack_long to work with TYPE_CODE_BOOL and
275 Wed Jun 19 18:04:08 EDT 1991
277 symtab.c Stored pervasive types in a structure and make
278 lookup_pervasive_type() a lookup function that was based
279 on working_lang. If lookup_pervasive_type() returned
280 non-zero, then that value was returned (a fix, since
281 before it simply wouldn't return the pervasive type.)
282 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
283 non-zero if the language specified by working_lang means
284 "conversion" when it says "cast".
285 valops.c Added the function value_real_cast(), which performs a
286 value.h *cast*, not a *conversion*, which is what value_cast()
287 does when it can. In particular,
288 value_cast(<float_type>,4) = 4.0, while
289 value_real_cast(<float_type>,4) = some mess.
290 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
291 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
292 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
293 and MIN on integral types. *NOTE*: These are currently
294 hardcoded to work only if there are 8 bits per storage
296 eval.c Made logical functions call value_bool to return a
297 properly typed boolean value, based on working_lang.
299 Thu Jun 20 11:55:27 EDT 1991
301 valprint.c Types now print out in a Modula-2 fashion. This works for
302 the cases when the type is printed out step-by-step, that
303 is, it doesn't work when the name of a structured type
304 (which includes the keyword "struct", etc.) is simply
306 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
307 since type specifications in C and Modula-2 are very
308 different. The C printing of a type is very recursive,
309 whereas in Modula-2 it is generally very simple. C has
310 type prefixes and suffixes, which have no real analogue in
311 Modula-2. Maybe type_print() should call a language
312 specific type printer. This is also advantageous if we
313 compile GDB to exclude some of the languages. We'll just
314 leave those functions out.
316 Thu Jun 20 16:57:10 EDT 1991
318 dbxread.c When reading the complete symbol table in (via
319 psymtab_to_symtab()), the number and types of function
320 arguments are added to a function type. define_symbol()
321 calls add_param_to_type() to accomplish this.
322 Assumption: when we come across a function definition
323 (N_FUN symbol with an 'f' or 'F' in the name), its
324 arguments will appear before another function definition.
325 When a function is found, a pointer to its type is placed
326 in the global in_function_type. Changes that
327 add_param_to_type() makes are to this global.
328 valprint.c The type of a function now includes (for Modula-2) the
329 types of its parameters.
330 eval.c Type checking and a check for the proper number of
331 arguments is now done for function calls. Not sure of the
332 impact this has on C++ member function yet.
334 Thu Jun 20 19:58:48 EDT 1991
336 valprint.c Rewrote the type printer. Broke it into two language
337 specific parts, adding the functions type_print_m2() and
339 An unfortunate consequence is this: if you debugging a C
340 program in Modula-2 mode (why?), info types does not work
341 well with regular expressions, since the types are printed
342 out in Modula-2 terminology, but stored in C terminology.
343 language.[ch] Added the functions new_type_last(), type_keyword(), and
344 type_sep() to aid in the printing of typedefs.
345 symtab.c Made the printing of typedefs as language independent as
346 possible through calls to new_type_last(), type_keyword(),
349 Fri Jun 21 11:50:26 EDT 1991
351 dbxread.c Check all incoming ennumerated types. If it looks like
352 Modula-2's BOOLEAN type, then change the type_code of the
353 type to TYPE_CODE_BOOL so we can process it as a boolean
355 valprint.c Replaced some of the 0x%x with calls to sprintf and
356 hexformat() in val_print().
357 language.[ch] Added the function hex_to_string(), which converts its
358 integral argument to a hexadecimal number (format is
359 language based) and returns the result as a string.
361 Mon Jun 24 12:25:07 EDT 1991
363 valprint.c Some functions call type_print_1() directly, instead of
364 value.h using type_print(), so they can specify where (column) to
365 print things. Since type_print() takes care of language
366 dependence, that needs to be called first. Added a
367 parameter depth to type_print() (so it is now like
368 type_print_1). Changed type_print to type_print_at, and
369 made type_print a macro that passes a depth argument of
371 symmisc.c Changed all calls to type_print_1 to calls to
373 Makefile.dist Made it possible to build GDB for a specific set of
374 depend languages. Do this by passing a definition for the macro
375 LANGS to make. LANGS should be a string containing a
376 space-separated list of language names (ie. LANGS="c m2").
377 The default is to build all languages. Note that grammar
378 files must follow the naming convention of <lang>-exp.y.
379 gdb.lang This holds the current value of the LANGS macro. It is
380 examined every time make is called, and is updated if
382 eval.c Added #ifdef _LANG_<lang> to these files.
383 expread.c Still need to add them to dbxread.c and coffread.c.
391 Mon Jun 24 16:33:11 EDT 1991
393 language.[ch] Added the functions hexformat_pre() and
394 hex_to_string_pre(), which take a prefix argument to
395 include in the format string. Thus, hexformat_pre("08") will
396 return "0x08x" (if the working language is language_c).
397 Made hexformat() and hex_to_string() calls to the above
398 with "" as the prefix argument.
400 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
401 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
402 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
403 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
404 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
405 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
406 valprint.c, vax-pinsn.c
408 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
409 calls to hexformat() and hex_to_string(). Format strings without
410 the leading "0x" were ignored.
412 depend Updated to take the above into account.
415 Tue Jun 25 15:27:18 EDT 1991
417 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
418 and type_check_t to keep track of the current state of
419 range and type checking.
420 main.c Added the variables range_mode, range_check, type_mode,
421 and type_check to record the current state of range and
422 type checking. Added initialization code to main().
423 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
427 Tue Jun 25 17:57:08 EDT 1991
429 dbxread.c process_one_symbol() updates the variable (enum language)
430 source_lang based on the extension of the filename
431 contained in the N_SO sybmol that started this symtab.
432 When end_symtab() is called, the value of source_lang is
433 put into the language field.
434 stack.c select_frame() sets working_lang (and possibly type_check
435 and range_check) to the language field of the symtab
436 associated with the frame that is selected if working_mode
437 is language_auto. If working_mode is language_manual, a
438 warning is printed and working_lang is not set.
439 language.c Added the function set_type_range(), which sets the value of
440 type_check and range_check (if their modes call for
441 automatic setting) based on the current value of
442 working_lang. A non-zero argument will cause the current
443 settings to be output.
446 Wed Jun 26 14:51:40 EDT 1991
448 eval.c Added range checks on assignment.
449 m2-exp.y Added the grammar for sets to the language. Currently,
450 these do not do anything except print an error message.
452 Wed Jun 26 17:01:04 EDT 1991
454 m2-exp.y Added the ability for parse_number() to parse negative
455 numbers. A global flag is set upon encountering a unary
456 minus. This was done to make, for example, 1 parse as a
457 CARDINAL, and not as an integer, per Wirth's examples in
458 Programming in Modula-2 ed.4.
459 valprint.c Added support for "set radix 2" by then setting
460 output_format to 't'.
461 eval.c Implemented range checking on subrange types. Added calls
462 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
463 Implemented MIN and MAX for ennumerated types. The
464 minimum value of an ennumerated type is defined by Wirth
465 as the first identifier, and the maximum as the last.
466 m2-exp.y Made octal numbers ending with "B" be characters and those
467 ending with "C" be numbers, per Wirth's book. (p. 34)
469 Thu Jun 27 14:11:52 EDT 1991
471 stack.c select_frame() now only sets working_lang, it does not
472 notify the user. If working_mode is language_manual, then
473 a warning is issued once.
474 main.c At the end of each call to execute_command(), working_lang
475 is checked against the local static (enum language)
476 current. If they differ and working_mode is
477 language_auto, the new settings of language, type and
478 range checking are printed out.
479 stack.c Modified frame_info() to include the language of the
480 current frame in the output of "info frame".
481 language.[ch] Added the function language_str() which returns the name
482 of the current language.
484 Fri Jun 28 15:33:14 EDT 1991
486 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
487 the language. INCL and DECL currently cause an error,
488 since sets are not implemented yet. INC and DEC are
489 implemented as PREINCREMENT/PREDECREMENT with one
490 argument, and as ASSIGN_MODIFY with two arguments.
491 eval.c Added type checking to the above cases.
492 value.h Added not_lval_constant to the lval_type ennumerated type.
493 not_lval_constant means that the value is a constant
494 value; that is 3 or 'a' or TRUE, not as in a constant
495 identifier. This is used to help coerce numbers such as 3
496 to either signed or unsigned numbers.
497 valops.c Added the function value_coerce_constants() which coerces
498 constant integers as following: if one is a constant and
499 the other is not, the constant's type is set to the type
500 of the other argument. If both are constants and one is
501 signed, the other is converted to a signed constant.
503 Sat Jun 29 17:26:29 EDT 1991
505 valarith.c Added a better range checker. It now checks range
506 (successfully) on integral operations [+-] (signed and
507 unsigned) for any C sized type. Still does not work well
509 int_in_size() returns an integer that is coerced to fit into
510 specified number of bytes.
512 Mon Jul 1 13:04:14 EDT 1991
514 language.[ch] Added the function binop_result_type(), which returns the
515 builtin (struct type *) type that would be the result of a
516 binop on the two values V1 and V2.
518 Wed Jul 3 19:22:53 EDT 1991
520 source.c Extended source_info() to include the source language in
521 the output from "info source".
523 Fri Jul 5 13:48:52 EDT 1991
525 utils.c Moved the support functions for the GDB set/show commands
526 dealing with language into language.c.
527 language.c Added the function language_info(), which displays info
528 about the current working language, type and range check
529 settings. Called via the GDB command "info language".
530 Added an initialization routine _initialize_language(),
531 that sets defaults for the language, type and range
532 variables and sets up the new GDB commands.
533 main.c Language setup moved to language.c.
536 Mon Jul 8 10:10:22 EDT 1991
538 valarith.c Debugged the range checker for arithmetic. Still does not
539 work for multiplication very well.
541 Mon Jul 8 12:40:37 EDT 1991
543 language.[ch] Added the function value_true() which returns non-zero if
544 its argument represents a boolean true value.
545 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
546 check the truth of an expression.
548 Thu Jul 11 12:51:34 EDT 1991
550 language.[ch] Added the predicate structured_type(), which returns
551 non-zero if the argument is a structured type.
552 Added the predicate pointer_type(), which returns non-zero
553 if the argument is a pointer type.
554 eval.c Added the ability to do addition and substraction on
555 pointers and integers. This case simply bypasses the
558 Thu Jul 11 14:41:42 EDT 1991
561 Added the symbol N_DEFD (0x4a) which is a definition
562 module dependency that is used by the GNU Modula-2
563 compiler and the linker. It is not important to GDB,
564 except that [dbx|coff|mips]read.c should ignore these
567 Fri Jul 12 16:07:00 EDT 1991
569 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
570 0 in val_print(). Also added statements to the else part
571 to coerce type (argument to val_print) to a pointer type
572 if it is an "array of unspecified length".
573 valops.c Added the function value_m2_string(), which returns a
574 (value) value which is a constant string, whose type is
575 (ARRAY [0..n] OF CHAR). The length field of the type
576 structure is set to zero, so it will be interpreted as an
577 "array of unspecified length".
578 stack.c Moved the language/frame mismatch check to
579 main.c:execute_command().
580 main.c The working language is recorded each time
581 execute_command() is executed. If working lang has
582 changed during its execution, then the new
583 language/type/range info is printed out for the user. If
584 the working language does not match the language of the
585 frame, a warning is issued.
587 Sat Jul 13 16:16:39 EDT 1991
589 eval.c Moved all the type-checking stuff for operators to
590 language.[ch] language.c. This is so we can keep language-specific
591 stuff (like for what type operators are defined) in
593 language.[ch] Added the function binop_type_check(), which checks to see
594 if its two (value) arguments are type-compatible with its
595 opcode argument. The opcode should represent an operation
596 involving an operator. Also added the macro function
597 unop_type_check, which calls binop_type_check with a
598 NULL second argument.
599 expprint.c Added Modula-2 operators to the op_print_tab, so info
600 expression.h break works correctly. Also added "op_string", which
601 returns the string corresponding to the (enum exp_opcode)
602 opcode that is its argument.
605 Sat Jul 13 18:26:18 EDT 1991
607 coffread.c Added code to record the type of function arguments with
608 each paricular function. Code is very similar to that
610 dbxread.c Moved add_param_to_type() to symtab.c
611 symtab.[ch] Added function add_param_to_type() from dbxread.c
613 *** NOTE: The above additions have not been tested.
615 Mon Jul 15 12:50:47 EDT 1991
617 langauge.[ch] Added the functions type_error and range_error, which work
618 like error() except if the type/range mode is set to
619 *_mode_warn, then they do not do a return_to_top_level(),
620 but merely print a warning.
621 Also changed [set|show]_[type|range]_command() to support
622 the new "warn" feature.
624 Thu Jul 18 17:50:54 EDT 1991
626 mipsread.c Added code to record the type of function arguments with
627 each particular function. Code is very similar to that
630 *** NOTE: The above additions have not been tested.
632 Fri Jul 19 11:19:10 EDT 1991
634 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
635 UMIN_OF_SIZE, which when given a size of a numeric type,
636 return the maximum and minimum value it can hold. UMAX...
637 and UMIN... return the result for unsigned types.
638 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
639 struct types. They call above macros.
640 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
641 avoid a name conlict with the above.
642 c-exp.y Added range checking on numeric constants in
643 parse_number() for completeness.
644 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
645 return 0 if working_lang is not language_c.
647 Thu Aug 8 14:17:22 EDT 1991
651 breakpoint.c Documentation strings of some commands changed to
652 eliminate the references to the C language where
655 Tue Aug 13 15:48:03 EDT 1991
657 m2-exp.y Added qualified identifiers to the grammar. The semantics
658 are slightly different from those of the GDB operator ::
660 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
661 type_exp, where type_exp is any valid type expression.
663 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
664 printcmd.c Modified ptype_command() so it actually parses the input
665 (necessary for type expressions with scope qualifiers).
666 Added the function ptype_eval() which expects an
667 expression composed of one OP_TYPE element.
668 *.[ch] Replaced all occurences of parse_c_expression with
670 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
672 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
674 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
676 Small fixes from Peter Schauer:
678 * infrun.c (child_attach): Lint.
679 * solib.c (find_solib): Handle shared libs version 2.
681 Small fixes from David Wood:
683 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
687 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
688 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
690 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
691 chars_per_line is at maximum (user typed `set width 0'). Fix
692 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
694 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
696 * coredep.c: include ptrace.h where necessary.
697 * mipsread.c(parse_lines): fix unsigned char problem that was
698 messing up line numbers on SGI's and possibly other MIPS based
700 * infrun.c (child_create_inferior): use better test to check
701 return val from setpgrp().
702 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
703 for sgi/irix support.
705 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
707 * mipsread.c (parse_symbol): Put non-static procedures
710 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
712 Patch together `text_start' and `text_end' for 29K port.
714 * exec.c (exec_command): If NEED_TEXT_START_END, define the
715 variables and set them based on the exec file.
716 * am29k-tdep.c: declare text_start.
717 * valops.c (call_function_by_hand): declare text_end.
719 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
720 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
721 because machines that do this will also have to know to
722 set NEED_TEXT_START_END. Besides, it was a redundant way to
724 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
725 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
728 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
730 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
732 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
733 Pass MUNCH_DEFINE to munch whenever we run it.
734 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
735 format string; use 0x%x instead.
736 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
737 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
738 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
739 * inflow.c: Handle `short' process group IDs.
740 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
741 and check for ptrace errors.
742 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
743 (coff_symfile_init): Initialize text_bfd_scnum.
744 (read_coff_symtab): Use it to find the text [and absolute?] sections.
745 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
746 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
747 Merge target arm case with other "easy" cases. Add target
748 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
749 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
751 * minimon.h, remote-adapt.c, remote-mm.c: Add.
752 * munch: Cope with RT/PC putting fns in data segment.
753 Restore ability to override `nm' by specifying MUNCH_NM.
754 * xconfig/rtbsd, xconfig/ultra3: New host systems.
755 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
756 and remote-adapt. Remove encapsulated coff #define's (the
757 support should go in BFD, and gdb shouldn't know or care).
758 * tconfig/a29k-kern: Same, but for remote kernel debugging.
759 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
760 * tm-29k.h: Update BADMAG (though it should go away).
761 Allow the register definitions to be overridden in another
762 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
763 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
764 DUMMY_SAVE_GR96, for handling kernel calling conventions
765 that use GR64+ rather than GR96+.
766 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
767 remote debugging of Ultra3 kernel. Includes tm-29k.h and
768 overrides various things.
770 * remote-mm.c (mm_attach, mm_wait): Handle attach like
771 child_attach does, making a clean stop in the newly attached
775 * coffread.c: Make coffread independent of any particular
776 variant of COFF. Avoid #include-ing any particular one except
777 internalcoff.h. BFD now passes key values for symbol reading
778 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
779 and the symbol masks and shifts); use them.
780 Remove obsolete end_of_text_addr.
782 * exec.c: Remove unused include files.
784 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
786 * Makefile.in (documentation targets): Pass $(M4).
787 Bugfix from eggert@twinsun.com (Paul Eggert).
789 * stack.c (down_silently_command): Check for stack existence.
791 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
793 * Makefile.in (VERSION): Update to 4.0.3.
795 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
797 * core.c (core_file_command): Print frame at coredump with
798 its level number, by calling print_stack_frame.
799 * frame.h: Add selected_frame_level, print_stack_frame.
800 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
801 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
802 Change print_sel_frame and print_selected_frame callers to
805 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
806 * symfile.c (free_named_symtabs): Ditto.
807 * main.c (main): wrap_here needs an arg.
808 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
809 (solib_add): Avoid noise.
810 (solib_create_inferior_hook): Lint.
811 (sharedlibrary_command): Move dont_repeat to here.
812 * utils.c (error): Call wrap_here to force buffered output.
814 Small patches from Peter Schauer:
816 * coffread.c (start_symtab): Free any existing line_vector before
818 (read_coff_symtab): Ditto for type_vector.
820 * source.c (lines_to_list): New variable, replacing function.
821 (all uses): Use as variable.
822 (_initialize_source): Add 'set listsize' and 'show listsize'.
823 * utils.c (lines_to_list): Remove function.
824 * stack.c (print_frame_info): Use as variable.
825 * defs.h (lines_to_list): Remove declaration.
827 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
829 * breakpoint.c (insert_breakpoints): Restore warning about
830 the program might be running in another process, but only for
831 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
832 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
834 * utils.c (error): if error_pre_print is set, print the string
836 * main.c (main, print_gnu_advertisement, print_gdb_version):
837 Reformat legalese so it always prints, but acts as an "I'm here"
838 message while symbols are being read. If any errors occur,
839 print a few newlines to set off the message and start it at the
840 left margin. Remove mention of "help" command, and don't yak
841 about symbol reading.
842 (catch_errors): Error string is now printed first in case of
844 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
845 suggest the "help" command.
847 * Makefile.in (VERSION): Set to 4.0.2.
849 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
851 * .gdbinit: Remove useless "rr" command. Set complaints
852 to 1 for people debugging gdb.
854 * breakpoint.c, remote-vx.c: Reword strings printed by
855 catch_errors callers.
857 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
859 * WHATS.NEW: "history write -> history save". Doc "write on/off".
860 (Fix from kenc@viewlogic.com.)
862 Fix some infrastructure to be able to cope with host and target
863 machines with different sized basic types (ints, ptrs, etc).
864 (Idea from pierre@la.tce.com (Pierre Willard).)
866 * values.c (value_from_longest): Rename from value_from_long.
867 Handle pointer types as well as integers, so that targets with
868 different pointer sizes from the host can be accomodated.
869 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
870 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
871 uses of value_from_long to value_from_longest.
872 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
873 the correct pointer type to value_from_long{est}.
875 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
877 * remote-vx.c: Remove obsolete code for calling functions via
878 vxworks kludge interface (it referenced value_from_long).
880 * valops.c (value_string): Find malloc with lookup_misc_func, not
883 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
885 Make writing to files work properly. (Fixes to BFD are also needed.)
887 * core.c (core_open): Open file ourselves, read or r/w, depending on
888 write_files. Use bfd_fdopenr.
889 * gdbcore.h (write_files): New variable.
890 * exec.c (write_files): Define variable, add set&show for it.
891 (exec_file_command): Use write_files to open for read or r/write.
893 Make shared library reading happen automatically. These changes
894 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
896 * inferior.h (stop_soon_quietly): Add to exported variables.
897 * infrun.c (child_create_inferior): call solib hook, if defined.
898 (child_attach): call solib hook, if defined.
899 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
900 (find_solib): Use lookup_misc_func rather than hand-rolled.
901 (symbol_add_stub): New stub for catch_errors.
902 (solib_add): Avoid output if !from_tty. Catch errors rather
903 than just calling symbol_file_add and bombing.
904 (solib_create_inferior_hook): Interface with the target process
905 to let it read and alloc shared libs, then figure out what it did.
907 * core.c (validate_files): Fix typo, soften warning.
908 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
910 * utils.c (fputs_demangled): Avoid duplicate printing if
911 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
913 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
914 (Fix from pierre@la.tce.com (Pierre Willard).)
916 * main.c (catch_errors): Change argument to a char * from an int,
917 since a char * can point to a struct full of glop, but an int
918 is not guaranteed to be able to hold a pointer.
919 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
920 breakpoint_re_set_one, breakpoint_re_set): Adapt.
921 * core.c (core_open, solib_add_stub): Adapt.
922 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
924 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
926 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
927 by adding .NOEXPORT target.
929 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
933 * Makefile.in (VERSION): Roll to 4.0.
934 (gdb.tar.Z): Make refcard.ps as well, for shipment.
936 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
938 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
941 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
944 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
946 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
947 reflect above name change
949 * WHATS.NEW: correct pointer to refcard.
951 * doc/gdb.texinfo: update New Features, Installing
953 * doc/gdbint.texinfo: add short description of configure +template
955 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
957 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
959 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
961 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
962 tar file, add dependencies for referenced doc files.
964 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
966 * coffread.c, symfile.c, stack.c: saberized.
968 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
970 * doc/refcard.tex: permuted Essential Commands sec
972 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
974 set/show symbol-reloading
975 default set complaints 0
977 RET-repeat disabled after prompted long displays
978 processID (attach) interpretation of 2nd GDB cmdline arg
980 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
982 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
983 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
984 breakpoint.c, main.c: lint.
986 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
988 Install new configuration scheme for GDB and friends.
990 * config.sub: Translate ordinary names to three-part names.
991 * configure: Use three-part names internally.
992 * configure.in: Translate three-part names to filenames.
994 * README, WHATS.NEW: Update for gdb-4.0.
995 * Makefile.in: Roll VERSION to 3.99.
997 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
999 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1000 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1001 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1002 to single structures rather than arrays; when passing
1003 their address, use &. This avoids trouble with bdead compilers.
1004 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1005 instead. This avoids portability headaches.
1006 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1008 * source.c (open_source_file): Avoid ANSI const bdeath by
1009 skipping declaration and then casting result value.
1010 * tm-hp300bsd.h: Clarify comment.
1011 * utils.c (strstr): Result is const char *; ANSI bdeath.
1012 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1013 since system include file defines it differently from "defs.h",
1014 though the two are equivalent for our purposes.
1015 * tconfig/hp300bsd: Add m68k-tdep.o.
1017 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1019 * tconfig/sun*4: Remove warnings about system assembler.
1021 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1023 * mcheck.c: Avoid warning about undeclared abort fn.
1024 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1025 it causes recursive calls to error() when used in cleanups.
1026 To do so requires that we make it a function, so we do.
1027 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1028 * utils.c (do_cleanups): Remove the current cleanup from the
1029 chain *before* calling it, in case error() is called from it.
1030 The result won't be pretty, but won't be an infinite loop either.
1032 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1034 * dbxread.c (read_struct_type): Grok anon structs for C++.
1035 (vb_name, vptr_name): Null terminate these strings.
1037 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1039 Minor bug fixes from BSD Net2 gdb:
1041 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1042 returns 0, there is no previous frame.
1043 * breakpoint.c (commands_command): If !from_tty, don't call
1044 input_from_terminal_p().
1045 * dbxread.c (record_misc_function): Speed up slightly.
1046 (compare_psymbols): Ditto.
1047 * infcmd.c (do_registers_info): Take a second argument to
1048 determine whether to print float registers. "info registers"
1049 does not do so anymore. "info all-registers" does, now.
1050 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1052 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1053 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1057 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1058 executing_breakpoint_commands if we are interrupted by error.
1059 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1060 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1061 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1062 catch_errors() so we can setup the frame regardless of whether
1063 the shared libs work.
1064 * ieee-float.c (double_to_ieee_extended): Get exponent from
1065 right place in little-endian systems. From John Carey.
1067 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1069 * main.c: Remove unused terminating_signals and catch_termination().
1070 (long_options): Terminate with a zero element.
1071 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1072 (gdb_readline): Make call-compatible with readline.
1073 (init_signals): Improve comments re vfork vs. signal.
1075 * utils.c (prompt_for_continue): Use new gdb_readline().
1076 If we prompt for continuation, we don't let CR repeat the previous
1077 command, once we get back to a prompt. It's too easy to keep
1078 hitting CR, expecting "--more--" prompts, and have some long
1079 command start repeating on you.
1081 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1083 * blockframe.c (frameless_look_for_prologue): Speed up by
1084 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1085 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1086 Define two variants, one faster.
1087 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1088 and return zero, rather than giving an error.
1089 (setup_arbitrary_frame): Initialize the PC in the new frame.
1090 (skip_prologue): Add a second arg saying whether we're just
1091 checking for a frameless function or not.
1093 * core.c (core_open, core_close, core_xfer_memory): Move
1094 section table pointers and bfd* into the target_ops.
1095 (core_open): Allow errors in shared lib reading, etc.
1096 (core_files_info): Describe shared library sections.
1098 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1099 exec_files_info, set_section_command): Move section table
1100 pointers and bfd* into the target_ops.
1101 (add_to_section_table): Add BFD to section table.
1103 * target.c (target_xfer_memory, target_info): Pass target to
1104 xfer_memory and target_info functions.
1107 * gdbcore.h: Move struct section_table.
1108 * target.h: New home of struct section_table.
1110 * solib.c (solib_add): New argument is the target_ops whose
1111 section list is to be added to, if any. Reallocate the
1112 sections in that target to add any that come from shared libs.
1113 (throughout) so_sections renamed to sections.
1114 (solib_xfer_memory): Deleted.
1115 * tm-sunos.h (SOLIB_ADD): Add target argument.
1116 (SOLIB_XFER_MEMORY): Delete.
1118 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1119 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1120 from target_ops. It's the same on all targets. Add two section
1121 pointers to target_ops.
1123 * stack.c (find_relative_frame): Dump ancient algorithm for
1124 "down", just use handy "next" pointers.
1125 (frame_command): Don't error if there is no stack; let user
1128 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1129 modifies static state in the parent process; new_tty itself
1130 runs in the child and modifies the child's file descriptors
1131 to match the saved static state.
1132 * infrun.c (child_create_inferior): Call new_tty_prefork,
1135 * infptrace.c (child_xfer_memory): Add ignored target arg.
1136 * remote-eb.c (eb_xfer_inferior_memory): ''
1137 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1138 * remote-vx.c (vx_xfer_memory): ''
1139 * remote.c (remote_xfer_memory): ''. Rename from
1140 remote_xfer_inferior_memory.
1142 * main.c (main): Only try to attach "corefile" argument if
1143 it starts with a digit.
1145 * symfile.c (symbol_reloading): New "set/show" variable.
1146 (symbol_file_add): Shorten message about symbol reading.
1147 (add_symbol_file_command): Merge with add_syms_addr_command,
1148 since this should work on all targets now.
1149 (stop_whining): Default to zero, to shut up complaints
1150 about bad symbol tables on many systems.
1151 (free_named_symtabs): Just exit unless symbol_reloading.
1153 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1154 and add comment explaining shared library screw.
1156 * source.c: #if defined => #ifdef.
1158 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1160 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1162 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1164 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1165 (doc/Makefile knows how to make one for local config)
1167 * Makefile.in: use doc/Makefile for doc targets
1169 * doc/Makefile: GDB documentation now has its own Makefile
1170 doc/refcard.tex: renamed from "gdbrc.tex"
1171 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1172 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1175 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1177 * values.c (baseclass_addr): When reading target memory, use the
1178 length of the basetype, not the upper type. We've only malloc'd
1179 enough space for the basetype, leading to errors in free().
1181 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1182 ends up as a function specially, since we know the actual type of
1183 the pointed-to address. This (somewhat) fixes display of
1184 expressions that include misc_function_vector names. Try `cond 1
1185 !strcmp("a","b")' then `i b'.
1187 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1188 The child can be proceeded from inside wait_for_inferior in
1189 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1190 getting skipped in that case.
1192 * expprint.c (print_subexp): Use filtered output, since the
1193 subroutines we call use it, otherwise the output is horribly
1194 mangled, since output of wrappable stuff comes out late.
1196 * Makefile.in: Bump VERSION to 3.98.1
1198 * infrun.c (child_create_process): Use execlp to find the
1199 shell to exec our target program. This requires some fiddling
1200 with `environ' since there is no execlpe().
1202 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1204 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1205 Minor rearrangement of refcard permits two new make targets--
1206 gdbrc.dvi DVI output for refcard, using CM fonts
1207 gdbrc.ps PostScript refcard, using PS fonts
1209 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1213 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1214 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1216 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1218 * doc/gdb.texinfo: last changes for release.
1219 Minor typo and formatting fixes; incorporated most fixes remaining from
1220 filed mail commenting on earlier drafts.
1222 Added warnings: pipes don't work in run command;
1223 conditions are converse of assertions;
1224 step over fn without debug info goes to next fn;
1225 vars may have "wrong" values near fn entrance, exit
1227 Added example from Kingston on printing repeated nonadjacent values
1229 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1230 shell mode for signals
1232 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1233 doesn't sound so much like its parent "Stopping and Continuing"; also
1234 moved entries on continue to top of section, so they don't get lost.
1236 Improved installation directions in appendix, added manual formatting
1239 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1241 * configure.in: Remove xm.h and tm.h even if we aren't linking
1242 new ones, so "./configure sun4; ./configure none" does the right
1243 thing. Assume that alldeps.mak and depend are already built in
1244 srcdir, and avoid running "make" (particularly "make depend",
1245 which involves "gcc") from inside configure. Build Makefile
1246 directly rather than building Makefile.conf first.
1247 * configure: Regenerate with above changes.
1248 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1249 to 3.98. Revise gdb.tar.Z procedure to produce a file
1250 called gdb-$(VERSION).tar.Z but which unpacks into a
1251 directory called "gdb". Move non-source files out of
1252 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1253 (depend): Don't try to do "gcc expread.y".
1254 (expread.o): Update dependencies by hand.
1256 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1259 Fixed a variety of small typos that prevented info from formatting
1260 cleanly; altered too-long heading for GPL Appendix, as discussed
1261 w/RMS; Changed date on cover to July 91.
1263 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1266 (1) Applied some fixes due to comments from Larry Breed (easier ones
1267 through chapsec 5.2)
1268 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1269 it's broken in latest texinfo
1270 (3) Introduced *some* use of [] for optional arguments, where
1271 explanation is not simpler by listing cmd w arg and cmd w/out arg
1272 separately. Still not using @deffn.
1273 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1274 couple of headings are too long. Need patches to texinfo or revision
1277 * Partial update to README (which still needs work for this
1278 release!): (1) use of configure corrected for new script,
1279 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1281 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1283 * symtab.c (lookup_symbol): Don't complain right off about
1284 no debug symbols; use the misc function vector first.
1285 (list_symbols): Use misc function vector to find symbols
1286 that don't have debug info, and print them.
1287 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1288 PC range doesn't match symtab PC range, as it does on the
1289 MIPS because our symtab reading isn't perfect.
1291 * dbxread.c (dbx_symfile_read): Make warning about
1292 "no debug symbols" slightly nicer.
1294 * source.c (select_source_symtab): If "main" symbol exists,
1295 but decode_line_spec can't find line info, don't just return
1296 a zero; try other source symtabs or give an error.
1298 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1299 their low addresses first, then rip through fixing high addrs.
1301 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1302 <runene@ifi.uio.no>.
1303 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1305 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1307 * Minor, mostly mechanical, cleanup of doc subdir for clean
1308 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1309 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1311 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1313 Mostly MIPS and general symbol-reading fixups.
1315 * doc/gdbint.texinfo: Add documentation on symbol-reading
1318 * mipsread.c: Remove kludges around #include "ecoff.h".
1319 Remove redefinitions of a_magic, etc, no longer used.
1320 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1321 Fix global overview comments to match symfile.c protocol.
1322 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1323 (mipscoff_symfile_read): Eliminate unused code. Avoid
1324 sorting all the symtabs, when all we have read here is psymtabs.
1325 The symtabs are sorted as they are created anyway. Tell
1326 condense_misc_bunches whether we're mainline.
1327 (psymtab_to_symtab_1): Pass filename when recursing, to make
1328 stack trace more informative.
1329 (parse_partial_symbols): Assume cur_hdr as argument.
1330 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1331 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1332 the TYPE_NAME of char *, since that's done in symfile.c.
1333 (free_numargs, parse_symbol, add_symbol, add_block,
1334 shrink_linetable): Declare these fns void.
1335 (upgrade_type): Convert tree of if's to switch. Clean up
1336 bogus "off == 0" handling with a complaint. Avoid setting
1337 field bitpos and bitsize of array with lower and upper bounds.
1338 Check specified bitsize of elements against their actual type's
1339 bitsize, and complain if different. Complain about unknown
1341 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1342 (psymtab_to_symtab_1): Print names of subsidiary files that
1343 are being read in. FIXME, we read far too many files. This code
1344 is not the problem, the problem is in parse_fdr where the psymtabs
1346 (cross_ref): Result should indicate that we used one aux entry
1347 normally, or two if we encountered a "next" entry. This used
1348 to leave the caller pointing at the wrong aux entry.
1349 (add_symbol): If overflowed cur_block, reallocate it larger,
1350 chase all pointers to it, and complain(), rather than clobber memory.
1351 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1352 (new_field): Only allocate one field initially, not two.
1353 Pull ++ out of macro argument. Simplify.
1354 (_initialize_mipsread): Avoid initialization of importd
1355 global_psymbols and static_psymbols.
1357 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1358 to properly set pst->symtab; avoid searching for it.
1359 (symfile_fns): Improve comments, add a FIXME.
1360 * dbxread.c: Update comments to reflect symfile protocol.
1361 (read_ofile_symtab, end_symtab): Return the symtab.
1362 (psymtab_to_symtab_1): Set pst->symtab.
1364 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1365 whether we're mainline.
1367 * symfile.h (sym_fns): Remove unused sym_discard member.
1368 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1370 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1371 the environment variable is not.
1372 * infcmd.c (finish_command): Use filtered printfs.
1373 * cplus-dem.c: Add struct tags to a few unnamed structs.
1374 * valops.c (value_coerce_array): Improve comments.
1375 * valprint.c (type_print_varspec_suffix): Print array size only
1376 if greater than zero.
1377 * m88k-tdep.c: Shift some lines left by one space, that had
1378 apparently been trashed at some point.
1379 * TODO: More things to do, a few got done.
1381 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1383 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1384 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1386 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1387 * expread.y, findvar.c, symmisc.c: Ditto.
1388 * printcmd.c (address_info): Update printed forms of LOC_
1389 symbols. Elim LOC_EXTERNAL.
1390 (print_frame_args): Keep track of param stack offsets before
1391 re-looking up to find the local register param is kept in.
1393 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1394 Further integration of mipsread into gdb. Eliminate unused
1395 routines, duplicate declarations. Handle static symbols in
1396 psymtabs as well as external symbols. When reading symtabs,
1397 insert symbols into the correct block (global, static, or a local
1399 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1401 (mipscoff_symfile_read): Don't call select_source_symtab.
1402 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1403 rather than SYMBOL_VALUE.
1404 (parse_external): Comment clobbering of top_stack.
1405 (parse_partial_symbols): Update comments. Allocate and parse
1406 static symbols as well as external symbols. FIXME, enum values
1407 are not handled in this pass, but should be. Inline new_psymbol.
1408 Use SYMBOL_VALUE_ADDRESS.
1409 (psymtab_to_symtab_1): Read symbols into global static block
1410 by default (until enter some function's local block context).
1411 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1412 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1414 * source.c (select_source_symtab): Select a source symtab
1415 from either the symtabs or, failing that, the psymtabs.
1416 (list_command): Update error message.
1417 (forward_search_command, reverse_search_command): Use getc, not
1418 fgetc, for speed. FIXME, add comment about buffers that die if
1419 overrun by long line.
1421 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1422 by an entire word, which is not portable, if we have a 32-bit
1423 field. (Code in dbxread.c already turns such bitfields, if
1424 aligned, into ordinary ints, but fixing this will help for other
1425 symbol formats and for future changes.)
1426 * core.c (core_open): Handle ANSI const brain death.
1427 * utils.c (vprintf): Fix varargs typo.
1429 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1431 * findvar.c (find_var_value): Handle &function better.
1432 * TODO: Document work needed on &fn and &array.
1433 * printcmd.c (print_address_symbolic): New arg is the prefix
1434 to print if a name is printed.
1435 (print_address_demangle): Honor "set print address" now.
1436 Use new arg above to improve spacing of output.
1437 * valprint.c (val_print): When printing function pointers,
1438 print symbolic form too.
1439 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1441 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1443 * core.c (memory_error): Reword error msg to mislead less.
1445 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1447 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1448 parse_partial_symbols): Use newer BFD internals (external_filehdr
1449 and external_aouthdr), byte-swap the fields that we care about
1450 before using them, and make the file header data local to
1451 read_the_mips_symtab rather than global.
1453 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1455 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1456 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1458 * main.c (command_line_input): Flush stdout and stderr
1459 before every call to readline. This reportedly fixes a bug
1460 that comes up in Sys V running emacs-gdb and/or xxgdb,
1461 when stdin/out are pipes or sockets.
1463 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1465 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1466 Avoid declaring Makefile dependencies, because GNU Make stupidly
1467 tries to update it if we do.
1469 * coffread.c: Revise for minor changes to bfd internal coff
1472 * configure: If -template= is given a relative path, make it
1473 absolute before recurring in subdirectories.
1475 * configure, configure.in, Makefile.in: Install "configure" script
1476 as replacement for config.gdb.
1477 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1478 * README: Update for configure, mostly. FIXME.
1480 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1481 target config files that they are for the host. When the lines
1482 get copied into the Makefile, this makes it more obvious what's
1485 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1487 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1488 tabs, which end up in the disassembler output inadvertently.
1490 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1492 Make it compile cleanly in an ANSI GCC2 environment.
1494 * blockframe.c: <stdio.h>
1495 * cplus-dem.c: free takes a void *, ifdef __STDC__
1496 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1498 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1499 * stddef.h, stdlib.h: Remove these files.
1500 * symtab.c: Avoid declaring qsort, close.
1501 * symfile.c: Avoid declaring close.
1502 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1503 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1505 Assorted other changes.
1506 * dbxread.c: include "libaout.h", not "liba.out.h".
1507 * printcmd.c (print_frame_args): Set recurse properly for
1508 indentation of struct and array parameters.
1509 * valops.c (value_cast): Allow cast to void.
1510 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1511 single_step() in a target-independent fashion.
1512 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1513 set up to be ready to continue. This makes us target independent.
1514 * infptrace.c (child_resume): Remove call to single_step; now
1515 can single step a SPARC target of any kind.
1517 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1519 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1520 docn into separate sections---basically chapters, plus two loose
1521 pieces that can be configured to go in different places. This
1522 allows GNU m4 to preprocess the manual without coredumping.
1524 * Makefile.dist: tell TeX where to find texinfo.
1526 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1528 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1529 the new target "rdl-apps.texinfo" which captures the Makefile
1530 variable that records where to find the Readline libraries.
1532 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1534 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".
1535 * tm-tahoe.h (FIX_CALL_DUMMY): Ignore more parameters.
1536 * defs.h (const, volatile): Only define if not already defined.
1537 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1539 * README: Update for release 3.95.
1540 * config.gdb: Don't create readline dir in subdir builds.
1541 * main.c: Include with "..." form for non-system include files,
1542 so "gcc -MM" for "make depend" works.
1543 Include readline files with "...h" rather than <readline/...h>.
1544 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1546 * coffread.c: Undo minor damage done by Rich Pixley. Use
1547 different internal and external representations of COFF
1548 data structures. Use new BFD routines for swapping them in and
1550 * symfile.c (free_named_symtabs): Avoid freeing file names that
1551 are null or empty. Old i960 tools seem to produce files that
1552 claim to have empty names, causing each successive file read
1553 to blow away the previous one.
1554 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1555 Move deferred_stores to top of file, but don't separate its
1556 #define's from its variable. Add commentary.
1557 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1558 favor of keeping the (working) config.gdb. Move readline
1561 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1563 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1565 * infptrace.c (fetch_registers): no result, since now void.
1566 * tconfig/news: target depends on m68k-tdep too.
1568 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1570 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1573 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1574 applied various small fixes due to or inspired by RMS comments
1576 * doc/gdb.texinfo: finished using all RMS comments, save those for
1577 appendices on readline and cmd history (which are in other source
1580 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1582 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1583 chapter 9; (2) documented 'break' command's menu mode for
1584 overloaded names, in response to hgs problem report C++ p-31
1586 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1588 * doc/gdb.texinfo: (1) better introductory example; (2) more
1589 consistent use of @code, @samp, @file, @kbd throughout; small
1590 cleanups to first three nodes; (3) new "Contributors" node;
1591 (4) Appendix, Renamed Commands; (5) divert specialized startup
1592 instructions to "Targets" chapter for generic manuals, while
1593 leaving them up front for manuals specific to specialized
1594 environments; (6) apply fixes from RMS comments through chapter 4.
1596 * pretex.m4: modify explanatory text slightly (and redefine
1597 "regexp") to keep GNU m4 from complaining. (It still crashes
1598 later, but one step at a time...)
1600 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1602 * readline/readline.c (update_line): Avoid dereferencing a pointer
1603 before comparing it to its bounds. Saber caught this.
1604 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1605 and only set PC if tgetstr returned non-null. Saber caught this.
1607 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1609 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1610 stuff for config manual) here where it counts; updated
1611 to use new subdir structure (gdb/doc/).
1613 * Makefile: generated from above via
1617 * gdbint.texinfo: added instructions on generating gdb.info* files
1618 locally for release. These are ordinary info
1619 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1620 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1621 to generate these, so we distribute them already formatted.
1623 * gdb.texinfo: included full Info node and menu crud (as generated
1624 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1626 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1627 put in comments-for-future gdb.info target (one day makeinfo will
1630 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1632 * gdb.texinfo: Updated to include new or old undocumented
1633 commands, at least the following (perhaps some others I forgot to
1634 record): info f, info float, info path, info program, info s, info
1635 set, info source, info terminal, info types, info user, set/show
1637 Also covered all recent GDB command renames for v4.
1639 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1641 * mipsread.c: Rather than keeping count of how many symtabs
1642 and psymtabs we have, for sorting purposes, count them when
1643 we need to sort. This fixes bug in rereading of symbol tables.
1645 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1647 * infcmd.c: renamed "info path" to "show paths"

1662 symtab.h, target.c, target.h: Lint.
1663 * core.c: setup and select frame after reading shared libs,
1664 else reading shared libs will clobber them. Lint.
1665 * utils.c (error): Force out any buffered wrap text.
1667 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1669 * remote.c: Remove decls of memory_insert_breakpoint
1670 and memory_remove_breakpoint, no longer used. (Suggestion of
1673 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1674 to make it easier to interface to "configure"'d libraries.
1676 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1678 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1679 aliases for set/show print.

2190 (add_target): Call add_cmd and mess with targetlist->doc.
2191 core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
2192 remote-vx.68.c, inftarg.c, remote.c: Add doc field to target struct.

2222 command is add-symbols.
2223 * target.c (dummy_target): Permit add_syms_addr_command.
2225 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2227 Permit symbols to be superseded when new symbol files have
2228 been read in, particularly for VxWorks.
2230 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2231 to the main file, as well as to include files. Also, put global
2232 functions into the global psymtab, to make "i fun" work.
2233 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2234 new psymtab for it has been read.
2235 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2236 a file, once a new symtab has been read for it.
2237 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2238 looks harder to determine the top-level block before it's been
2239 queued to the psymtab list.
2241 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2242 If we have wiped out any old symbol tables, clean up at end of
2244 (symbol_file_command): Don't reference symfile_fns if it's zero.
2246 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2247 defines for the blocks of a blockvector that contain global and
2248 file-static symbols and the first of the smaller scope contours.
2249 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2250 decode_line_1, make_symbol_completion_list): Use the above.
2251 * coffread.c (end_symtab, patch_opaque_types): Ditto.
2252 * dbxread.c (end_symtab): Ditto.
2253 * expread.y (block): Ditto.
2254 * mipsread.c (throughout): Ditto.
2255 * symmisc.c (free_named_symtabs): Ditto.
2257 * symtab.c (list_symbols): Process the first symbol of the
2258 static psymbols list.
2259 (types_info): Restore this function from its untimely #if 0.
2260 It's not perfect, but it is better than nothing.
2261 (_initialize_symtab): Restore "info types".
2263 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2265 * m68k-stub.c: Remote stub for 680x0's, created from
2266 rem-m68k.shar (which is removed).
2267 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2268 Remove RCS log stuff now that we use CVS and it blows our diffs.
2270 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2272 * symmisc.c (free_named_symtab): Make it work, in its current
2273 kludgy fashion. Change result to indicate if we blew away bkpts.
2274 * dbxread.c (end_symtab): Accumulate result from
2275 free_named_symtab and print warning if we blew user's state.
2276 * symfile.h: free_named_symtab now returns an int.
2278 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2280 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2281 is the first symbol read, even if not mainline.
2282 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2283 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2284 (set_section_command): New command ("section xxx yyy" -- should
2285 be renamed to "set section xxx yyy" FIXME) which sets the
2286 base address of a section of the exec file, overriding the
2287 virtual address that BFD reports.
2289 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2291 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2292 load symbols at any address while examining an exec file.
2294 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2296 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2297 for printing the float info is host-dependent, not
2298 target-dependent. FIXME.
2299 * i386-pinsn.c: Move #includes to top, remove useless ones.
2300 * i386-tdep.c: Don't bother including <.../reg.h> since we
2301 don't use it (and it doesn't exist on host systems).
2303 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2304 Convert negative numbers properly.
2305 (ieee_test): Make numbers really random; fix format arg.
2307 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2308 * core.c (core_detach): Unpush core_ops, which might not be on
2309 top. We used to just pop the top, which broke things. Don't
2310 need dont_repeat() any more.
2311 (core_file_command): Psst! Don't repeat it.
2312 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2313 * expprint.c (print_subexp): Avoid switch fallthru on
2314 BINOP_ASSIGN_MODIFY, so we can print += and such.
2315 * frame.h: Fix typo.
2316 * inflow.c (kill_command): After killing inferior, print our
2317 current frame in the core file, if we have one.
2318 (generic_mourn_inferior): When inferior dies, either select
2319 the current frame (in the new target, e.g. core file), or
2320 set both the current and selected frames to NULL.
2322 Changes from Peter Schauer.
2324 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2326 * Make all file names fit in 14 characters (sigh and damn!):
2327 mv hp300hpux-xdep.c hp300ux-xdep.c
2328 mv symmetry-xdep.c symm-xdep.c
2329 mv symmetry-tdep.c symm-tdep.c
2330 mv convex-opcode.h convx-opcode.h
2331 mv tm-vxworks960.h tm-vx960.h
2332 mv tm-vxworks68.h tm-vx68.h
2333 mv Makefile.srcdir Makefile.sdir
2334 mv gdb-int.texinfo gdbint.texinfo
2335 mv remote-sa.m68k.shar rem-m68k.shar
2336 mv remote-multi.shar rem-multi.shar
2337 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2338 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2339 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2342 * command.c (user_info_1, user_info): New command for listing
2343 the user-defined commands.
2345 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2347 * dbxread.c (really_free_pendings): Clear file_symbols
2348 and global_symbols after freeing them; otherwise, running
2349 this function twice (if it appears twice on the cleanup
2350 chain), we try to free things twice.
2352 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2353 based on text_addr (the address of text in core), not on addr (the
2354 offset between text in the .o file and in core). This change
2355 is from Peter Schauer.
2357 * main.c: Define ALL_CLEANUPS as a cast of zero.
2358 (return_to_top_level): Use it.
2359 (main): Do all cleanups after each command run as part
2360 of the gdb startup sequence. Also do all cleanups before
2361 entering the command loop, and every time we exit the command
2362 loop and reenter. Before, the cleanups from the startup sequence
2363 were being left undone until the first error!
2364 (command_loop): Rename do_nothing cleanup to command_loop_marker
2365 so we can see it easily when examining the cleanup chain.
2366 (init_signals): Add another do_nothing for signal handling.
2367 (quit_command): Only try to kill target if it has execution.
2368 Problems in the target stack got us into a state where
2369 inferior_pid was nonzero but none of the targets had execution.
2370 In this state you couldn't exit gdb.
2372 * dbxread.c: Two changes from Peter Schauer.
2373 (echo_command): Fflush output after an echo command.
2374 (show_history): Pass all args to cmd_show_list.
2376 * utils.c (init_malloc): Call mtrace to turn on tracing
2377 if the environment variable MALLOC_TRACE is set to a file name.
2378 * mtrace.c: Add source file which provides a log of every malloc,
2379 free, and realloc to a trace file.
2380 * mtrace.awk: Add source file which analyzes the trace file.
2381 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2382 (VERSION): Roll to 3.94.3.
2384 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2385 (check_duplicates): Don't bother with watchpoints.
2386 (set_raw_breakpoint): Comment about danger of this routine.
2387 (watch_command): Parse and eval all args before calling
2390 * solib.c (find_solib): Avoid error in referencing memory to
2391 see if any more shared libraries have been added. This is
2392 particularly useful if the target has terminated. Bug reported
2395 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2396 in bringing up 3.94.2 on the Sun-3.
2398 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2399 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2400 expression (in scope) before reenabling watchpoint.
2401 * signame.c (init_sigs): Add missing declaration of i, fix
2402 sys_siglist declaration.
2403 * source.c (list_command): Fixed range computation to use
2405 * stack.c (backtrace_command): Do not allow command if target has
2406 no stack, print informative error message.
2407 * target.c (target_command): Do not write into command line
2408 because this fails if the target command is used in a user defined
2409 command. [This change was enhanced by gnu to support any-
2410 unique-prefix matching on target names.]
2411 * valops.c (value_struct_elt): Avoid infinite loop on an
2412 erroneous attempt to print the member of function (try p main.p).
2414 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2416 * expread.y (name_no_typename): Avoid reduce/reduce errors
2417 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2418 Since the GDB parser really doesn't use name_no_typename in a
2419 name-only context, the parser can't tell the diff between
2420 names and numbers here. Avoid allowing a name_no_typename
2421 to be a NAME_OR_*INT to resolve the conflict.
2423 Sun Mar 31 20:12:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2425 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2427 * valprint.c (val_print_fields): bitfield printing didn't handle
2428 byte order. Indirect through a few more fns to cope.
2430 * values.c (modify_field): also cope with byte order.
2432 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2434 Cleanup for release 3.94.2:
2436 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2437 include files. Roll version to 3.94.2.
2439 * coffread.c (init_stringtab): Read length into unsigned char
2440 array before swapping; don't assume 32-bit longs.
2442 * target.c (target_info): Don't bother with get_sym_file, just use
2443 the symfile global variable.
2444 * symtab.h, symfile.c (get_sym_file): Delete it.
2446 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2447 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2448 (read_type): Replace one more error() with complain().
2450 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2452 * i960-tdep.c: Fix copyright attribution.
2454 * config.gdb: Quote all backquotes in doublequotes. You can
2455 quote me on that. BSD 4.4 shell found this one.
2457 * infptrace.c (throughout): The third argument to ptrace is an
2460 * infrun.c (wait_for_inferior): When program has terminated, we
2461 have to call target_terminal_ours before we pop that target off
2462 the stack (e.g. before a call to target_kill or
2463 target_mourn_inferior). This fixes problem where a program
2464 terminates, then GDB stops for (tty output) and you have to type
2465 "fg" to the shell to resume it. FIXME: This code for what to
2466 do after termination really should be in normal_stop instead.
2468 * gdbcore.h (read_memory_check): Change declaration; it changed
2471 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2472 4.4 prereleases, this avoids a bug in their sgtty compatability
2474 * remote.c: Use terminal.h rather than hand-rolling the same.
2476 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2477 * utils.c (strsave, strstr): Fix arg types.
2478 * valprint.c (val_print): lint
2480 MIPS symbol table support from Per Bothner:
2482 * symfile.c (symtab_fns): Remove initializer table that needs to
2483 be hacked for each new symbol file format supported.
2484 (add_symtab_fns): New function, chains symbol table
2485 handlers into the global list.
2486 (symfile_init): Search this list.
2487 * symfile.h: Add next pointer, declare add_symtab_fns.
2488 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2489 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2491 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2492 symbol *). Thus, we no longer need the hack to trash
2493 pst->filename. Good, since that hack confused code in symfile.c!
2495 (reorder_symtabs, destroy_all_symtabs): Removed static
2496 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2497 Instead, the latter now uses a temporary array (stack-allocated
2498 from an obstack, and then freed).
2500 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2501 haven't been set in the outermost stBlock of a procedure. This was
2502 a problem with f77 binaries on Ultrix 4.?.
2504 (new_symtab, new_symbol, new_type): Continue changing code to use
2505 obstacks more and otherwise conform to dbxread internal style.
2506 Made the free_code of symtabs be free_linetable (as in dbxread)
2507 instead of free_contents. This implies memory leaks when reading
2508 a new symbol table, until the conversion is finished. Did change
2509 (struct symbol) and (struct type) to be allocated on the
2510 symbol_obstack. Blocks and blockvectors are among the things
2513 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2514 tested much, but it solved one problem (reported by Meissner), and
2515 cleans up some other things. The problem happened when an
2516 included file contains actual code (functions) and not just
2517 definitions. The mips coff is a little inconvenient there, since
2518 it may cause a procedure to be mapped to the wrong psymtab.
2520 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2521 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2522 this will need work for the new core paradigm.
2524 Opcode patches from the net:
2526 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2527 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2528 missing altogether - they are added here. From Bruce Bauman.
2529 * mips-opcode.h: The low mask for C0 instructions was too small.
2530 From Garrett Lau. I modified the fix to check the entire 32-bit
2533 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2536 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2538 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2540 * dbxread.c (read_type): Pointer subtraction (value_sub in
2541 valarith.c) sometimes failed because the types of the
2542 pointers being subtracted were not identical.
2543 These differed because dbxread.c was allocating pointer types
2544 using dbx_alloc_type+smash_to_pointer_type instead of
2545 lookup_pointer_type. I failed to find a justification for the
2546 former, so I changed it to use the latter. Similarly, I
2547 replaced smash_to_function_type by lookup_function_type,
2548 and smash_to_reference_type by lookup_reference_type.
2550 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2551 _initialize_mipsread): corresponding changes.
2553 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2555 * source.c (mod_path): Do tilde_expand on each component of the path,
2556 rather than on the (list of) paths as a whole.
2557 (print_source_lines): Set first_line_listed in addition to
2558 current_source_symtab and current_source_line. If the source was
2559 not findable, after a "dir" command to fix the problem,
2560 a "list" would get the wrong lines.
2562 While I was there... (gnu):
2564 * dbxread.c (read_type): Change error to complaint.
2566 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2568 First attempt at detailed understanding of symbol table memory alloc.
2570 * dbxread.c (dbx_symfile_read): Free our string table if we
2571 aren't the mainline. Free the "info" struct since we're done with
2573 (init_psymbol_list): Free any previously allocated psymbol lists.
2574 (): FIXME: Should realloc-down the psymbol lists when done reading
2575 the main symbol file?
2577 * symmisc.c (free_symtab): Free fullname field too.
2579 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2580 (REGISTER_ADDR): Make result type unsigned int.
2582 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2583 define REGEX must also define REGEX1 (its dependency).
2585 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2587 * tconfig/i960: No longer works, points you at vxworks960 or
2590 * xgdb.c, XGDB-README: Remove file. Users can get the much
2592 * Makefile.dist: Remove all trace of xgdb.
2594 * breakpoint.c (breakpoint_1): Pass demangle arg to
2595 print_address_symbolic.
2596 (clear_breakpoints): Remove unused function.
2597 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2598 (breakpoint_re_set): Use catch_errors to do them all anyway.
2600 * gdb-int.texinfo (Host versus Target): Add section on what is
2601 a "host" feature versus what is a "target" feature.
2603 * infcmd.c (path_command, path_info): Handle the PATH variable
2604 (object search path) as conveniently as the source search path.
2605 * environ.c (set_in_environ): Set some vars in GDB's environment,
2606 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2607 * source.c (mod_path): New function, from guts of
2608 directory_command, modifies a path. Used by path_command.
2609 (directory_command): Call it.
2610 * defs.h (strsave): Declare.
2612 * utils.c (sevenbit_strings): Add new printing option.
2613 (printchar): Use it.
2614 (strsave): Provide this handy helper routine.
2615 (set_width_command): Rename set_screen_width_command.
2616 (_initialize_utils): "set screen-width" => "set width";
2617 "set screen-height" => "set height"; add sevenbit-strings.
2619 * infcmd.c (do_registers_info): Print floating point registers
2620 in raw hex as well as float format, regardless of whether it is
2621 a "virtual" convertible register.
2622 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2623 regs as a double, just in case it's being used that way.
2624 * values.c (unpack_long): Comment on array/function coercion.
2625 (unpack_double): Argument is in target byte order now. For
2626 integer arguments, just call unpack_long and float the result.
2627 * m68k-tdep.c: include defs.h for "const" handling.
2628 * remote-nindy.c: Use ieee-float stuff.
2629 (nindy_fetch_registers): Unpack double regs to host double, then
2631 (nindy_store_registers): Pack extendeds to host double, flip
2632 around by misusing unpack_double, send as target double.
2634 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2635 zero, as when stopped at the first instruction of a process.
2637 * blockframe.c: Fix filename in comment (param.h => tm.h).
2638 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2639 * tm-68k.h: Fix typos.
2641 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2643 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2645 * coredep.c (fetch_core_registers): Pass end-address of register
2646 section to register_addr as expected. Don't call supply_register
2647 if we'd just pass it garbage.
2649 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2651 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2653 * target.c (push_target, target_info): Cast enums to int for < or
2656 * stack.c (print_frame_info): Identify source file & line
2657 even if we can't print it.
2659 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2661 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2663 Clean up IEEE floating point support.
2665 * ieee-float.h: New file.
2666 * ieee-float.c: Write real routines to convert between host
2667 doubles and various target IEEE extendeds.
2668 * m68k-xdep.c: Eliminate assembler code for extended floats.
2669 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2670 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2671 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2672 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2673 double_to_ieee_extended.
2674 * i960-tdep.c: Define ext_format_i960.
2675 * m68k-tdep.c: Define ext_format_68881.
2676 * sparc-tdep.c: Define ext_format_sparc, though unused.
2677 * Makefile.dist (HFILES): Add ieee-float.h.
2678 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2681 Obsolete the "coffstrip" program in favor of using BFD's strip.
2683 * nindy-share/coffstrip.c: Remove file.
2684 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2685 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2686 * tconfig/nindy960: Remove reference to coffstrip.o.
2688 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2690 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2692 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2693 * dbxread.c: Remove static symfile_bfd.
2694 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2696 * inftarg.c (child_detach): Pop the child_ops vector if the
2697 detach is successful.
2698 * remote-nindy.c (nindy_create_inferior): Don't push a new
2699 nindy_ops since nindy uses the same one for execution and memory
2701 * core.c (core_ops): Use child_attach and child_create_inferior
2702 rather than default attach and create_inferior functions.
2704 Handle floating point registers in core files.
2706 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2707 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2708 This version untested since BFD doesn't yet support sun3 core
2710 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2711 conventions. Fix comments and style. This version has not
2712 been compiled yet, since we have no HP inhouse.
2713 * core.c (get_core_registers): Look for two sections, ".reg"
2714 and ".reg2", and pass both to fetch_core_registers sequentially.
2716 Revise directory path yet again.
2718 * source.c (forget_cached_source_info): Not static any more.
2719 (init_source_path): New default source path is "$cdir:$cwd".
2720 (dir_command): Handle variable arguments ($cdir, $cwd).
2721 (source_info): Print "Compilation directory" rather than
2722 "Originally compiled in" to remind people of $cdir.
2723 (openp): If the path contains $cwd, use current directory.
2724 (open_source_file): If compilation directory is known, replace
2725 first $cdir in path with the compilation directory.
2726 (print_source_lines): Even if we can't print the lines, set the
2727 current symtab and line for future commands like "info source" or
2728 "breakpoint". Also, error message now contains the file name,
2729 line number, and file access error message.
2730 (_initialize_source): Fix help text to describe changes.
2731 * main.c (cd_command): Forget cached source info when we chdir.
2732 * utils.c (strstr): Add simple implementation.
2734 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2736 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2737 Byte-swap COFF symbol tables if necessary when reading them in.
2738 Use complain() to replace error message in one spot. Needs
2739 corresponding change in bfd/coff-code.h to make some symbol
2740 swapping routines non-static.
2742 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2744 Merge changes from Eirik Fuller, for UTek.
2746 * defs.h (errno): Add declaration.
2747 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2748 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2749 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2750 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2751 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2752 declarations of errno.
2754 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2756 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2757 <rpc/rpc.h> and <rpc/types.h>.
2759 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2761 * i960-tdep.c (examine_prologue): Add new argument limit,
2762 which stops the scan at the end of the prologue, or at the PC.
2763 This fixes a problem where it walks down into the code for the
2764 user's statements if that code looks like function prologues.
2765 Mark Fox and I have been bouncing this code back and forth, making
2766 small changes to it. Callers changed to match.
2768 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2770 Cleanup for gdb-3.94 release final:
2772 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2773 the .c files from vx-share and nindy-share, from the various
2774 macros, since they are not found via ALLDEPFILES.
2775 (SFILES): Add tm-i960.h.
2776 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2777 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2779 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2780 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2782 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2784 * am29k-tdep.c: Add contribution line.
2785 (examine_prologue): Cache information about function prologues in
2786 the misc-function-vector to avoid lots of references over the
2787 serial line while examining instructions.
2789 * core.c (core_close): New function made from cleanup_core.
2791 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2792 remote-vx.c, remote.c, target.c, target.h,
2793 Update target_ops vector to add attach, close, and load entries.
2794 Use add_syms_addr_command, not add_file_addr_command, for
2795 add_file. Break out close routine from existing code.
2797 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2798 they are in an obstack.
2799 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2801 (define_symbol): Add symbol type parameter; change callers;
2802 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2803 it to influence the symbol class on the i960.
2804 (define_symbol): Swap LOC_CONST's into target byte order.
2806 * exec.c (exec_close): New function.
2807 (exec_file_command): Call it.
2809 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2810 Fix byte order of frame pointer.
2811 (read_var_value): Result of 0 if var's value can't be found,
2812 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2813 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2814 (locate_var_value): Use read_var_value and use its lazy address
2815 as the location of the var's value. Lint.
2817 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2820 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2821 obsolete Intel versions in favor of vxgdb versions.
2822 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2823 code dealing with byte order of values, which Intel did in host byte
2824 order rather than gdb-4's target byte order.
2825 (i960_frame_chain_valid): Move to nindy-tdep.c.
2826 (examine_prologue, skip_prologue, frame_find_saved_regs,
2827 frame_args_address, leafproc_return, saved_pc_after_call,
2828 pop_frame): Add vxgdb versions from Mark Fox.
2829 (examine_prologue, frame_struct_result_address): Add code
2830 to deal with the saved value of G13 (struct return address
2832 (frame_args_address): Modify Mark's version to prefer the
2833 saved value over the current value in the topmost frame.
2834 Cache result in the frame info to avoid performance hair in
2836 (print_fault): Add gdb960 code for printing faults.
2837 (_initialize_i960): Actually call check_host.
2839 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2840 add stub routines. FIXME, these currently just return zero!
2842 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2843 (attach_command): Call target_attach, not target_open, now.
2845 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2846 (child_attach): Rename from child_open.
2847 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2848 don't confuse it with a zero step_resume_break_address.
2850 * inftarg.c (child_detach): Eliminate inferior_pid test.
2851 (child_files_info): Clean up message a bit.
2852 (child_ops): Use child_attach, not child_open, to attach.
2854 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2855 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2856 findvar.c to here, since it depends on the contents of the
2857 shadow_contents of breakpoints, but keep if #if 0 since it is
2860 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2863 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2864 (ptype_command, display_command): Eliminate have_inferior_p and
2865 have_core_file_p in favor of target_has_stack or
2866 target_has_execution.
2867 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2868 code for actually finding the values of arguments, though we still
2869 keep track of the maximum stack offset for use in printing unnamed
2870 arguments. Handle missing FRAME_ARGS_ADDRESS.
2872 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2873 (struct nindy_regs): Define registers passed to/from nindy.
2874 (nindy_fetch_registers, nindy_store-registers): Translate between
2875 nindy and GDB formats for the registers.
2876 (dcache_init): Statically allocate the cache, since it was being
2877 allocated by a malloc that was never freed anyway.
2878 (nindy_create_inferior): Error, not core dump, if no exec file.
2879 (nindy_before_main_loop): Use target_load, not target_add_file.
2881 * remote-vx.c (net_load): Specify large timeout for load
2882 requests. Allow user to break out with INTERRUPT.
2883 (net_break): Remove useless code, clean up. Change callers.
2884 (parse-args, skip_white_space, find_white_space): Clean up arg
2885 parsing to cope with quoted strings.
2886 (net_wait, net_quit): Never call error, just return status.
2887 (vx_read_register, vx_write_register): Cleanup status checking.
2888 #ifdef the code based on which CPU we are using (960 or 68k),
2889 FIXME, this should be completely general but it isn't yet.
2890 (vx_xfer_memory, vx_resume): Cleanup status checking.
2891 (vx_run_files_info): Improve message.
2892 (vx_load_command): Renamed from vx_add_file_command. Allow load
2894 (net_ptrace): Remove unused routine.
2895 (vx_wait): Adopt code from vxgdb960 to cope with broken
2896 connections to target machine and prompt to disconnect. Remove
2897 debug printouts. Map some EVENT_'s to SIGnals.
2898 (add_symbol_stub, vx_open): Print names of object files we found,
2899 and "ok" if we read their symbols OK. Clarify output in general.
2900 (vx_attach, vx_detach, vx_kill): Add these commands.
2901 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2902 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2903 "info files" output, and create_inferior, since we already have
2906 * stack.c (frame_info): Replace Frame_unknown with 0.
2907 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2908 (return_command): Pop until the PC matches as well as the FP,
2909 so it works even if the FP is shared with another function,
2910 as in "frameless" or "leaf" procedures.
2912 * symfile.c (load_command): renamed from add_file_target_command.
2913 (add_syms_addr_command): renamed from add_file_addr_command.
2914 (add_syms_command): Stub to call target_add_syms.
2915 (_initialize_symfile): Change command names and descriptions,
2916 add-file => add-syms, and load from alias to its own command.
2918 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2919 maybe_kill_then_create_inferior): Default for attempts to start
2920 a process, if one is already running, is to ask about killing
2921 it and retry if yes.
2922 (upstack_create_inferior): #if-0 it, strata obsolete it.
2923 (push_target, unpush_target, pop_target): to_close() a target
2924 before unstacking it.
2925 (target_info): Renamed from target_files_info.
2926 (_initialize_targets): Rename "i files" as "i target", accessible
2929 * target.h: Improve comments about the target_ vectored routines.
2931 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2932 Convert commenting style to standard GNU style.
2933 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2934 (SKIP_PROLOGUE): No longer a no-op.
2935 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2936 (*_REGNUM): Sort register numbers.
2937 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2938 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2939 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2940 are now 10 byte extendeds, not 8 byte doubles.
2941 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2942 for nindy versus vxworks targets. FIXME, this should possibly go
2943 in the target vector.
2944 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2945 frame_saved_regs and arg pointer with each frame.
2946 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2947 (FRAME_ARGS_ADDRESS): Use cached result.
2948 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2949 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2950 (PRINT_RAMDON_SIGNAL): Call print_fault.
2951 (POP_FRAME): Now works.
2953 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2954 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2955 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2956 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2959 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2960 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2962 * valarith.c (value_subscripted_rvalue): Avoid handling
2963 floats and doubles specially; it gave alignment errors. Lint.
2965 * valops.c (value_of_variable, value_of_this): Error if unknown
2968 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2969 to avoid alignment problems.
2970 (value_print): Handle unknown value address.
2971 (cplus_val_print): Two args are ignored; remove them. Change caller.
2972 (val_print): Use unpack_long rather than pointer-deref.
2975 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2976 to avoid alignment problems.
2977 (value_being_returned): Error if return value unknown.
2978 (set_return_value): Add bogosity warning, FIXME. *
2980 * TODO: A woman's work is never done.
2982 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
2983 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
2984 Add ieee-float.o to OBS.
2985 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
2986 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
2987 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
2989 Changes to generalize the VxWorks RPC protocol slightly, to handle
2990 i960 as well as 68000.
2992 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
2993 * vx-share/reg.h: Produce i960 regs #ifdef I80960
2994 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
2995 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
2996 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
2997 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
2998 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
2999 so they will move in target byte order rather than network
3000 byte order (happens to be the same).
3002 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3004 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3006 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3009 Add contribution lines to various files, showing where they
3012 * breakpoint.c (break_insn, check_break_insn_size,
3013 read_memory_nobpt): Remove to mem-break.c.
3015 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3018 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3019 entry has bad register number. This change is not
3020 tested in this release, FIXME.
3022 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3025 * value.h: Force value's contents field to be aligned to hold
3026 at least a double or a long long (if supported). This avoids
3027 doing bcopy's in and out of the contents field.
3029 (step_1): Avoid coredump under obscure circumstances when we
3032 * symtab.h (misc_info): Add field to misc function vector for
3033 any kind of cached information the target code desires. AMD
3034 29000 uses this to avoid repeating examine_function_prologue's.
3036 * coffread.c: Lint. Remove static symfile, read_section_header.
3037 core.c (have_core_file_p): Lint: remove.
3038 expprint.c (print_subexp): Lint.
3039 infptrace.c, valops.c, valprint.c: lint.
3041 Roll in changes from vxgdb-5.0.1:
3043 * symtab.h: Comment byte order of each address class. Add
3044 LOC_LOCAL_ARG for frame-relative args (960).
3045 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3046 symtab.c, symmisc.c: ditto.
3048 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3050 * remote.c (remote_resume): Error if resume with a signal.
3052 * symfile.c (prim_record_misc_function): Clear misc_info.
3053 (fill_in_vptr_fieldno): Check stub type of arg.
3055 * valops.c (value_cast): Avoid looking up names of types whose
3056 name we don't know, to prevent coredump. Sun CC produces typedef
3057 rtx and the name of *rtx is zero...
3059 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3061 Roll in changes from final AMD 29000 port (Tiemann).
3063 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3064 for ../include/a.out.encap.h. This might not work now that BFD
3065 is separately compiled. Instead, BFD support for encap will have
3066 to translate machine type 29k into the right COFF_MAGIC.
3068 * infcmd.c: Remove references to inferior_pid that aren't used
3069 in actual ptrace calls; use target_has_execution, etc.
3070 (have_inferior_p): Remove function.
3071 (program_info): Print target info rather than "process number";
3072 avoid gratuitous messages unless from_tty.
3073 (run_stack_dummy, finish_command): Set proceed_to_finish.
3074 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3075 main.c: Lint. Lose have_inferior_p().
3076 inferior.h (have_inferior_p): Remove, lint.
3077 (proceed_to_finish): Add flag to ask that all regs be saved
3078 by normal_stop, for the few commands that need it, speeding up
3079 serial I/O. Add comments to stop_registers.
3081 * remote-eb.c: Remove newline from breakpoint message we grep
3082 for. Never time out when running the user program.
3086 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3088 Roll in changes from vxgdb-5.0.1:
3090 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3091 symbol in its raw form, we are processing an unlinked ".o" file.
3092 See if the target environment has assigned it an address, using
3093 target_lookup_symbol (VxWorks does), and enter it into the symtab
3096 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3097 68k versions for a simpler version that assumes zero FP at bottom.
3098 Fixes bug of truncated stack reports.
3100 * target.h (target_lookup_symbol): Define this routine's args
3101 and result, finally.
3103 * target.c (nosymbol): Default routine for target_lookup_symbol.
3104 (target_default): Default lookup_symbol and call_function too.
3105 (files_info): Only print has_all_memory warning if a non-dummy
3108 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3109 vx_convert_from_virtual): If target does not have floating point,
3110 zero register "values", and avoid doing cross-net conversions.
3111 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3112 (vx_open): Rearrange code that attaches to target and reads
3113 symbols for all loaded modules, to work if some of the modules
3114 are not accessible. Add symbol_stub() and add_symbol_stub()
3115 as callbacks from catch_errors(). Allow connect attempt to be
3116 interrupted painlessly with ^C (FIXME, there are still some bugs
3117 if the interrupt happens during symbol reading.). Print
3118 final message with puts_filtered, since symbol messages are
3123 * main.c (catch_errors): Only print errstring if non-null.
3124 (command_loop): Avoid an ioctl per command to test ISATTY.
3126 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3127 (vx_xfer_memory): Return correct result!
3128 (vx_files_info): Indicate whether target has float or not.
3129 (vx_lookup_symbol): Complain, not error, if target gone.
3130 (vx_open): Print "Connected" msg before disabling immediate-quit.
3131 [FIXME: lookup_symbol and vx_open changes need testing.]
3133 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3134 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3135 contributor lines and update copyrights to 1991.
3137 Changes from an attempted H-PUX host port:
3139 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3140 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3141 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3142 * remote-vx.c: include <sys/time.h> for HPUX.
3143 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3144 "core_file_command" routine to BFD regime. May not work yet.
3146 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3148 * xgdb.c: Replace X10 version with some VJ version.
3149 (FIXME: Its copyright assignment is not on record.)
3150 * xgdb.c: Update include files to X11R4 (Xaw crud).
3151 (xgdb_display_source, create_text_widget): fix call to
3152 get_filename_and_charpos. Rewack source window stuff for X11R4
3153 (gleaned from include files, and "nm's" of binary libraries, since
3154 I had no doc available).
3155 (append_selection, append_selection_word): Disable with FIXME
3156 since R4 changed interface here.
3157 (create_buttons): Add back the old set of buttons.
3158 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3160 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3161 Roll VERSION to 3.94 (not yet final though).
3163 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3165 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3166 obstack_int_grow, obstack_int_grow_fast): Eliminate
3167 cast on left of assignment, which gives MIPS cc fits and is
3170 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3171 F_ALIAS. Use printf, not fprintf, when not passing a file
3173 (compare_opcodes): Check that identical instructions have
3174 identical opcodes, complain otherwise.
3176 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3177 was reported by Roland McGrath.
3178 (unimp): Only match if exactly zero instruction. (Roland)
3179 (branches and traps): Generate all variations of these
3180 instructions with macros, based on a single call that defines
3181 each condition name and its binary representation.
3182 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3184 * valprint.c (val_print_fields): Take, and use, format parameter.
3185 This means that "p/x struct" again prints the elements in the
3186 desired format. Changed callers.
3188 * stack.c (frame_info): Use filtered output, and indicate wrap
3189 points. Remove kludgy formatting designed to avoid line wrap.
3191 * utils.c (wrap_here): If the line is already full (because
3192 we had printed a long indent or long wrapped string), do an
3193 immediate newline-and-indent.
3195 * m68k-pinsn.c (print_insn_arg): Bugfix from
3196 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3197 instruction is incorrectly disassembled as bkpt #8.
3199 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3200 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3201 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3202 and then will dump core (sometimes). I traced it back to an
3203 uninitialized symfile_name in psymtab_to_symtab.
3204 (const_vol_complaint): Add quotes to message.
3205 (define_symbol): Only believe line number if gcc_compiled.
3206 Avoid allocating symbol if we will not return it.
3208 Add target strata support so that newly established targets go
3209 into their right place in the target stack (e.g. a new exec file
3210 doesn't wipe out the ability to access the running process).
3212 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3213 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3214 and initialize it properly in all the targets.
3216 * target.h: Document strata. Change return type of push_target.
3218 * target.c (nomemory): new function for dummy memory access.
3219 (tcomplain): Rename complain, now also used in symfile.c.
3220 (push_target): Push targets within strata. New return value shows
3221 whether new target is on top of stack or not. Always keep dummy
3223 (target_files_info): Ignore dummy target.
3225 * core.c (core_open): Warn user, and skip accessing file, if the
3226 core target is not the topmost target in the stack.
3227 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3230 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3231 target_ops, it doesn't belong there since we have no regs there.
3232 Change name of target from machine => memory to clarify.
3234 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3236 * Freeze version 3.93 for release.
3238 * Makefile.dist: Handle vx-share and nindy-share subdirs
3239 properly when building gdb.tar.Z.
3241 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3242 printed in various places, so I could change just one copy.
3244 * dbxread.c, coffread.c: Change references to bfd->iostream
3245 to cast to FILE *, now that BFD avoids needing types defined
3246 in other header files.
3248 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3250 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3251 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3252 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3253 (actually gcc -Wall).
3255 * dbxread.c: Remove first_global_sym, last_global_sym, since
3256 they are never referenced.
3258 * defs.h (baud_rate): Declare.
3259 main.c: Define it, and add the -b option to set it.
3261 * gdb-int.texinfo: Add text on how to define a new host or target
3262 architecture, prompted by Per Bothner's questions about MIPS
3265 * gdb.texinfo: Document "complaints". Change doc of -q since
3266 gdb no longer prints the copyright and blurb if you specify a file
3267 name to be debugged (just like Emacs). Add doc for Nindy-specific
3268 command line flags for specifying target serial port and such.
3269 Update copyright to 1991.
3271 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3272 has taken over for us the job of ripping up executable files. The
3273 crud caused Per Bothner's port to not compile.
3275 * infrun.c (normal_stop): Avoid printing "Program exited
3276 normally" if we are in batch mode. This allows a GDB which
3277 executes a program on a target system, to behave like a Unix
3278 command (input from stdin, output to stdout, no extraneous
3281 * main.c (main): Allow additional machine-dependent command line
3282 options to be specified with the ADDITIONAL_OPTIONS,
3283 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3284 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3285 processing to occur just before the main loop with
3286 BEFORE_MAIN_LOOP_HOOK.
3287 (main): If a "core file" argument is specified, and it is not a
3288 core file, try it as a process ID to attach.
3289 (symbol_completion_function): Attempt to cope with
3290 "show screen-" TAB, not very successfully. This needs more work,
3292 (batch_file): New function, returns whether we are reading
3293 commands from an interactive tty on stdin, or from somewhere else.
3294 Called by normal_stop since it doesn't get from_tty passed down
3295 to it like many commands do.
3297 * remote-nindy.c: Handle command line options for nindy
3299 (nindy_before_main_loop): Prompt user for tty name if they
3300 don't specify it before getting to the interactive command loop.
3302 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3303 and -r command line options. Also add hook before main loop
3304 to make it easy to specify a tty.
3306 * TODO: More things to do, one done.
3308 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3310 * dbxread.c: Make complaint() calls pass pointer, not struct.
3311 Add complaints about badly formatted C++ type information
3312 (const/volatile indicator, and parse errors resulting in
3313 error_type). Fix C++ virtual member fn comment.
3314 (read_struct_type): Avoid bumping pointer if we got a parse
3315 error; this prevents our walking beyond the end of a string.
3316 Terminate loop on null char as well as semicolon.
3317 (process_one_symbol): Fix the LBRAC fix so that it uses the
3318 last previous SLINE, FUN, or SO record's PC address. C++ debug
3319 symbols did not have SLINE records in a useful order compared
3320 to the LBRAC records.
3321 (define_symbol): Handle "catch" records.
3323 * symtab.c (check_stub_type): Added new complain
3324 `stub_noname_complain' and added a consistency check to
3325 keep the debugger from crashing when finishing from an
3326 exception frame. A real fix will be needed later.
3328 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3330 * infcmd.c (attach_command): Make global.
3332 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3333 but make them easy to comment out. Perhaps later they should
3334 be enabled by what CPU you configure for? FIXME.
3335 (VERSION): Roll to 3.93.
3336 (pinsn.o): Remove rule for obsolete file.
3337 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3339 Run down a problem that manifested by printing the wrong function
3340 name in stack traces of read_ofile_symtab. Turned out that the
3341 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3342 the LBRAC symbol with an address in the *data* segment, which
3343 blew our binary search through the blocks.
3345 * dbxread.c: Use the complain() facility consistently to bitch
3346 about problems in the symbol file we are reading.
3347 (finish_block): Add code to check the nesting of the blocks;
3348 complain and Procrust them to fit if wrong.
3349 (make_blockvector): Check the order of the blocks, complain
3350 [but don't cope] if wrong.
3351 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3352 symbols to be sure their PC value is greater than the last SLINE
3353 (line number) symbol we've seen, complaining and adopting the
3354 SLINE PC value if wrong.
3356 * symfile.h (struct complaint, complaint_root, complain,
3357 clear_complaints): Add.
3358 * symfile.c (complain, complaint_root, clear_complaints): Add
3359 facility to deal with non-fatal complaints and to regularize their
3361 (symbol_file_add): Clear complaint counters to allow new complaints.
3362 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3364 * dbxread.c (dbx_symfile_read): Remember the address and size
3365 of the string table for the main symbol file, so we won't read it
3367 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3368 to avoid reading the string table yet again. Lint.
3369 (throughout): Improve filtered output, including word wrap.
3370 (read_range_type): Improve Bothner's fix to handle other types too.
3372 * utils.c: Improve line wrap implementation. Handle unlimited
3373 width by making chars_per_line unsigned.
3374 (puts_filtered): New, easy, function.
3376 * defs.h (puts_filtered): add.
3378 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3379 call the identical sort_symtab_syms() in symfile.c instead.
3381 * expread.y: Suggest the `file' command rather than `symbol-file'.
3383 * command.h (enum var_types): Add zinteger for seroable
3385 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3386 nested if's into a switch.
3388 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3389 we did not stop because of a breakpoint (it must have been for
3390 some other reason, like a "stepi"), so don't print anything.
3392 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3393 doesn't include <sys/types.h>, old SunOS's require it for
3396 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3398 A test port of gdb-3.92.6 to the Sony NEWS.
3401 Don't normally link in remote- or vx stuff.
3402 Some of it doesn't compile, and it wastes space for 99% of the users.
3403 Remove reference to no-longer-used HAVE_VPRINTF.
3404 Fixed BFD_DEP typo to BFD_DIR.
3406 Fix cast in arg to bfd_h_getlong.
3407 Make char *prefix be const.
3408 Fix how certain range types are mapped into builtin unsigned int types.
3410 Remove 2 #includes. They cause errors (on Sony, at least),
3411 and aren't needed (they wern't in earlier versions).
3413 print_address_symbolic should never demangle labels
3414 (since it prints *assembler-level* labels).
3416 [This was superseded by the change to printcmd below.]
3419 Add some "volatile" return types to avoid warnings.
3420 If MISSING_VPRINTF add vprintf function and not just macro
3421 (since vprintf is used in printcmd.c).
3423 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3424 (The latter isn't grokked by some PCC-based compilers.)
3426 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3428 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3429 * nindy-share/coffstrip.c
3430 Added some forward declarations (otherwise, gcc complains
3431 about implicit extern redefined as static).
3433 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3435 Changes inspired by Per Bothner:
3436 * printcmd.c (print_address_symbolic): Take additional parameter
3437 specifying whether to demangle.
3438 (print_address): Pass in asm_demangle to control demangling.
3439 (print_address_demangle): New fn, takes explicit arg to control
3441 * utils.c: Add new vars demangle and asm_demangle, and let them
3443 (fputs_demangled): If !demangle, just print the argument.
3444 (fprint_symbol): If !demangle, just print raw symbol.
3445 * valprint.c (val_print): Call print_address_demangle rather than
3446 print_address, to cause demangling to depend on the global
3447 rather than assembler-level demangling setting.
3448 * WHATS.NEW, gdb.texinfo: Document.
3450 * main.c (show_command): Show all settings if no arg.
3451 (initialize_main): Make "info set" the same as naked "show".
3452 * command.c (cmd_show_list): Handle prefix commands in the
3453 list, and print the name of the setting as well as its English
3454 description and value.
3456 Allow gdb functions to specify where a line should wrap if it
3457 exceeds the size of a terminal line. Use it to make the output
3459 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3460 of the right size when screen width changes.
3461 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3462 (wrap_here): New fn, indicates a point in the output where we
3463 should wrap the line rather than just letting it overflow at a
3465 (fputs_filtered): Implement wrapping.
3466 (n_spaces): New fn, returns a pointer to N spaces.
3467 (print_spaces_filtered): Use n_spaces.
3468 * defs.h (n_spaces): Declare.
3469 * stack.c (print_frame_info): Wrap with 4-space indent after
3470 fn name and before filename and line number.
3471 * printcmd.c (print_frame_args): Wrap with 4-space indent
3472 before each argument name is printed.
3473 * valprint.c (value_print): Wrap with no indentation before
3475 (val_print_fields): Wrap with indentation relative to nesting
3476 level before each field name.
3477 (val_print): Wrap with nesting indentation before array elements.
3478 * command.c (do_setshow_command): Avoid extra newlines,
3479 wrap with 4-space indent around values printed, end with period.
3480 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3482 * breakpoint.c (breakpoint_1): Implement addressprint for
3483 "info breakpoints" display. Change file name and line number
3484 format to " at file:nnn" rather than " (file line nnn)".
3485 * gdb.texinfo: Document.
3488 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3490 Frozen for gdb-3.92.6 release.
3492 README, WHATS.NEW: Update for 3.92.6 release.
3494 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3495 coffread.o from configs since it is now built by default.
3496 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3497 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3498 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3499 from configs since it is now built by default.
3501 Makefile.dist: Update for release 3.92.6. Handle files that
3502 have been moved to ../include, ../getopt, or ../bfd. Add
3503 saber.suppress and tests directory. Add config.status to
3504 the release (it will say "none").
3506 coredep.c: Minor formatting fixes.
3508 These changes were made in early December but only checked in now:
3509 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3510 nindy-share/nindy.c: lint
3511 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3512 register values coming back from the target; we store values
3513 in target byte order everywhere.
3515 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3517 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3519 * valprint.c (cplus_val_print, val_print_fields): New functions,
3520 which print C++ objects. They conspire to avoid printing a
3521 virtual base class more than once, following all the twists and
3522 turns of C++ virtual base rules.
3523 (val_print): Call the above rather than do it by hand.
3525 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3526 symbol file, not for added files like shared libs. This really
3527 needs to be generalized to a timestamp per file.
3529 * core.c (cleanup_core): Avoid coredump if no core file.
3531 * config.gdb: Accept -host or -target in place of +host or
3534 * coffread.c (find_linenos): Avoid desupported BFD interface
3535 to line numbers. We still read them manually rather than using
3536 BFD's "generic" features.
3538 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3540 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3542 * Makefile.dist: Eliminate use of $< in explicit targets.
3544 * readline/Makefile: Use $< rather than $*.c, which does not
3545 include the VPATH in GNU Make.
3547 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3548 copies of tconfig/i960, added for global configuration
3549 compatability. All i960 versions can read both coff and b.out.
3551 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3552 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3555 * TODO: Think of more things to do.
3557 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3559 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3560 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3561 64-bit float conversion.
3563 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3564 equivalent to sun?os4 so global config works.
3566 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3568 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3570 * main.c: Only declare linesize once; declare pagesize not at
3571 all, since it is never used.
3572 (main): Clear newly allocated line before it is used.
3574 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3576 Further stabilization for the Intel 960.
3578 * Makefile.dist: Parameterize the location of the "include"
3579 and "bfd" directories, as well as "getopt". Add symfile.c.
3580 Link in both dbxread and coffread. Fix up "make depend" to
3581 rewack the locations of include, bfd, and getopt in its output.
3583 * README: Document moving include files, improve some of
3586 * coffread.c: Move common code out to symfile.c. Change
3587 symbol_file_command style interface to use new *_symfile_init
3588 and *_symfile_read interface under BFD. Use BFD internal
3589 info to locate line table, symbols, etc.
3591 * core.c (core_fetch_registers): Rename to get_core_registers
3592 to avoid confusion with fetch_core_registers.
3593 (register_addr): Move to coredep.c, which is already machine
3594 dependent. This leaves core.c pretty clean of dependencies.
3596 * coredep.c (register_addr): Accept this routine from core.c.
3598 * dbxread.c: Move common code (with coffread.c, etc) into new
3599 symfile.c. Each psymtab now contains a pointer to the
3600 format-dependent function that knows how to read it in. Make
3602 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3603 (process_one_symbol): Add code to complain about a "compiler bug
3604 we muzzle here", if we actually see it.
3606 * eval.c (evaluate_subexp): Insert missing "break" statements
3607 in code that determines whether a variable is an lvalue in
3608 memory, register, or whatever. I detected this via a compiler
3609 bug in which it *almost* mashed out the whole switch statement.
3611 * gdb-int.texinfo: Add minor sections on configuring gdb for
3612 release, and about the README file.
3614 * infcmd.c (registers_info): Fix formatting somewhat. Still
3615 not as pretty as before, but it handles byte swapping.
3617 * remote-nindy.c: If data cache routines are interrupted while
3618 waiting for the remote end, be sure that any uninitialized cache
3619 blocks are on the free list, not on the valid list!
3621 * symfile.h: Flesh out this header file with all the various
3622 routines and variables that have been merged in from dbxread.c
3623 coffread.c, and symtab.c to symfile.c.
3625 * symfile.c: New file, containing code common to dbxread.c,
3626 coffread.c, and some code from symtab.c. All generic code for
3627 reading symbol files should be in here now.
3628 (unrecord_misc_function): Remove unused function.
3630 * symtab.h: Remove file-reading things to symfile.h.
3632 * symtab.c: Remove file-reading things to symfile.c.
3634 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3635 to decode i960 fault types.
3637 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3638 target.c: Change type of the "resume" function from int to void,
3639 since its result was never used.
3641 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3643 * main.c: Replace "stupid" with "caution"; you now "set caution
3646 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3648 * infcmd.c (do_registers_info): Call val_print to deal with the
3649 byte order of the registers being printed. FIXME, this makes
3650 the formatting of the output uglier.
3652 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3653 defined, call it for signals the debugger doesn't itself use.
3654 The i960 uses this for more detailed fault information.
3656 * remote.c (remote_open): If arg is null, print help rather than
3659 * sparc-xdep.c (register_valid): Avoid declaring size, since
3660 various modules will think of various sizes depending on the
3661 architecture of their tm-file. FIXME, we need protection against
3662 actually entering one of those modules, which would clobber
3663 storage if not for the target architecture compiled into gdb.
3665 * stack.c (up_command, down_command): Always print the frame
3667 (up_silently_command, down_silently_command): New commands
3670 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3672 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3673 more parameters than it used to.
3675 * findvar.c (registers): Increase slop to 256 bytes, which should
3676 protect us against even most RISC machines with large register
3678 (locate_var_value): Move declaration inside related ifdef.
3680 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3681 throughout, to avoid throwing away buffered input from the board.
3682 (nindy_wait): Supply_register takes addr_of_value, not value.
3683 (i960_print_fault): Renamed from i80960_fault.
3684 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3685 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3687 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3688 we can set the PC in the call to proceed(). Unpush nindy_ops
3689 before pushing it on top, to avoid message to user. Eliminate
3690 commentary from Unix machines that just misleads here.
3691 (reset_command): Fix error message to suggest target command.
3693 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3695 Release 3.92.5 as frozen.
3697 Stabilize the merged release...with help from lint, Saber C,
3700 Everywhere: Add include files needed to declare return types
3701 of functions called.
3703 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3705 * breakpoint.h: Add undeclared breakpoint functions, and some
3706 functions for display handling since I couldn't think of a better
3709 * breakpoint.c (insert_breakpoints): Make code for disabling
3710 shared library bkpts more likely to work. It's used when we
3711 rerun a program and stop before the shared library has been
3713 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3714 cast from pointer, so it squeezes through catch_errors.
3715 (bpstat_stop_status): Fix logic broken some time ago. We now
3716 always create a bpstat if the stop address matches a breakpoint,
3717 even if we don't stop there -- just like the old code used to do
3718 before I got my fingers into it (sigh).
3719 (breakpoint_1): Print "ignore count" after "stop only if"
3720 condition, since that's how it actually works.
3721 (mention): Handle watchpoints as well as breakpoints.
3722 (watch_command): use set_raw_breakpoint and mention to do most
3723 of the work (and initialize all the fields!). Only pass one
3724 arg to parse_c_expression, since that's all it takes.
3726 * command.c (not_just_help_class_command): Rename arg to args
3727 since we ignore "unused argument" warnings on vars named "args".
3728 inflow.c (child_terminal_info): ditto.
3729 infptrace.c (kill_inferior): ditto
3730 main.c (catch_errors, version_info, quit_command, pwd_command,
3731 source_command, dump_me_command, editing_info,
3732 set_history_size_command, set_history, show_history,
3734 stack.c (locals_info): ditto
3735 target.c (target_files_info): ditto
3736 valprint.c (set_input_radix, set_output_radix): ditto
3738 * core.c: Remove old variables for handling core and exec file
3739 sections (data_start, data_end, stack_start, stack_end,
3740 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3741 text_end, exec_data_start, exec_data_end, text_offset,
3742 exec_data_offset, data_offset, stack_offset). They're
3743 superseded the more general build_section_table and
3745 (get_exec_file): Mention the `file' command.
3746 (read_memory_check): Rename to memory_error, and only call it
3747 in the case of an actual error.
3748 (read_memory, write_memory): call memory_error.
3749 (core_fetch_registers): Register section name is ".reg".
3751 coredep.c: Remove a bunch of crud now that all this file does
3752 is pull the registers out of a core file.
3753 (fetch_core_registers): Rewrite to actually work, I hope.
3755 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3756 Replace index() with strchr(). Remove all the pre-BFD macro
3757 definitions for accessing the symbol file.
3758 (struct dbx_symfile_info): Encapsulate the information that
3759 dbx_symfile_init needs to pass to dbx_symfile_read in this
3762 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3763 dbx_symfile_discard): Rearrange symbol file reading to divide
3764 the format-specific part from the format-independent part,
3765 leaving the format-independent part such as file name expansion
3766 and opening in symtab.c. This replaces
3767 partial_symbol_file_open and partial_symbol_file_read.
3768 Symbol_file_read, add_file, add_file_target_command,
3769 add_file_addr_command move to symtab.c. Pass an explicit
3770 "mainline" flag for when reading the main symbol table, rather
3771 than relying on the offset address to be zero or nonzero.
3773 (dbx_symfile_read): Don't allow void *'s to be printed as
3775 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3776 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3777 macro" debug version really work.
3778 (read_dbx_symtab): Remove unref'd parameter inclink.
3779 Avoid swapping N_SLINE symbols, for speed.
3780 Merge N_TEXT!N_EXT case with the other external symbol
3781 definitions' case. Add comments.
3782 (start_psymtab): Allocate the symfile name in the psymtab on
3783 the psymbol_obstack, rather than using the caller's storage.
3784 (end_psymtab): Only allocate a dependencies list if there are
3786 (psymtab_to_symtab_2): Use BFD when reopening file to read
3787 its symbols for real.
3788 (read_struct_type): Add FIXME comments where it needs work
3790 (read_huge_number): Add FIXME about overflows.
3791 (read_range_type): Add FIXME about comparing a long to 1<<32.
3793 * coffread.c: Minor changes to move things closer to the new
3794 regime with symtab.c and dbxread.c Major work is still needed
3797 * exec.c (exec_file_command): Remove old variables (see core.c
3799 (xfer_memory): If memory transfer is right at the end of a
3800 section, don't lose.
3802 * findvar.c (get_saved_register): If value is in a real
3803 register, LVAL is lval_register, not lval_memory.
3805 frame.h: Declare print_sel_frame and record_selected_frame.
3807 gdb-int.texinfo: New file, for GDB internals documentation.
3808 Very simple, unformatted doc of cleanups is there for now.
3810 gdbcore.h: Remove obsolete variables that described a.out
3811 section addresses and offsets. (See core.c above.)
3812 Declare fetch_core_registers and registers_fetched.
3814 getopt.c: Declare char *alloca(); even on SPARC.
3816 infcmd.c (run_command): Call target_kill rather than
3818 (step_command, next_command, stepi_command, nexti_command):
3819 Declare from_tty parameter even though we don't use it.
3820 (run_stack_dummy): argument BUFFER is a char array, not
3821 a pointer to REGISTER_TYPE.
3822 (finish_command): using_struct_return needed a value *,
3823 not a struct symbol *.
3825 * infptrace.c (child_xfer_memory): To avoid dependency on
3826 where sections are in memory, try PT_WRITE_D and if that fails,
3827 try PT_WRITE_I. Most Unixes don't care which you use.
3829 * infrun.c (step_resume_break_shadow): Change to array to
3830 match other breakpoint shadow storage.
3831 (clear_proceed_status): Pass address of bpstat to
3832 bpstat_clear, not the bpstat itself.
3833 (child_create_inferior): FIXME comment about if the child
3835 (start_inferior): Remove old function.
3836 (child_open): Use target_kill rather than kill_inferior.
3837 (wait_for_inferior): Ditto.
3838 (insert_step_breakpoint, remote_step_breakpoint): Use
3839 new step_resume_break_shadow.
3841 * inftarg.c (child_wait): If all child processes die,
3842 pretend that the one being waited for exited with signal 42.
3844 * main.c (command_line_input): When scanning for comments,
3845 don't coredump on unclosed quotes.
3846 (quit_command): Use target_kill rther than kill_inferior.
3847 (_initialize_main): Rename class_user from "user" to
3850 * printcmd.c (print_command_1): Initialize "fmt" if no format
3851 is specified by the user.
3852 (print_frame_args): Only add to args_printed if we are
3853 actually fetching args from the stack (avoiding undefined
3855 (_initialize_printcmd): Remove bogus \{ from string.
3857 * remote-eb.c (eb_open): Avoid coredump on no argument.
3859 * remote-nindy.c: Bring out of Intel environment into new
3860 target environment. Remove all conditional compilation on
3861 I80960. Massive hacking throughout.
3862 (nindy_xfer_inferior_memory): New routine stolen from
3864 (nindy_create_inferior): New routine pieced together, probably
3865 not quite working yet.
3866 (nindy_ops): New target_ops struct for nindy.
3868 * remote-vx.c: Use write_memory rather than target_write_memory
3869 to get error checking.
3870 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3872 (vx_create_inferior): Use target_terminal_ours...
3874 * signame.c (_initialize_signame): Always initialize, since
3875 we need the table for things other than psignal.
3877 * solib.c (solib_add): Use symbol_file_add, not add_file.
3878 (solib_address): Return boolean result rather than struct
3879 pointer which nobody else knows the type of.
3881 * sparc-tdep.c, valops.c: Use write_memory rather than
3882 target_write_memory, to get error checking.
3884 * stack.c (locals_info, catch_info, args_info,
3885 get_selected_block, frame_command, up_command): Use
3886 target_has_stack, rather than have_inferior_p or
3889 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3891 * symfile.h: New file, defining the interface between the
3892 generic and object-file-specific symbol reading code.
3894 * symtab.c: Move generic symbol-reading interface to symtab.c,
3895 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3896 table to map BFD targets to symbol-reading modules in GDB.
3897 Change index to strchr.
3898 (lookup_struct_elt_type): Use error() rather than hand-made
3899 simulations thereof.
3900 (lookup_partial_symbol): Speedup slightly when length == 0.
3901 (symbol_file_add): New function.
3902 (symbol_file_command): Call it.
3903 (symfile_open, symfile_init): New function.
3904 (add_file_target_command, add_file_addr_command): moved from
3907 * target.c (target_command): use target_kill.
3909 * target.h (target_files_info): Don't declare, never called
3912 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3913 files to determine stack end address.
3915 * valarith.c (value_x_binop, value_x_unop): Change error message
3916 to be more useful. Pass proper argument to value_struct_elt.
3918 * valops.c (value_assign): FIXME comment that long long
3919 bitfields will break here.
3921 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3922 Update `make saber_gdb' to work better.
3924 * TODO: A woman's work is never done.
3926 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3927 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3928 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3929 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3930 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3931 valops.c, valprint.c, exec.c: Lint.
3934 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3936 Continuing Intel 960 port merge of GDB.
3938 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3939 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3940 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3941 Wack over "make depend" so it handles files in subdirectories
3942 vx-share, nindy-share, bfd, and in the current directory.
3944 * blockframe.c (get_prev_frame_info): Remove fatal error
3945 if stack not defined.
3947 * core.c (core_open, core_detach): New functions that handle
3948 the old "core-file" command as "target core" and "detach" instead.
3949 (core_file_command): Call them.
3950 (core_xfer_memory): Use common routine xfer_memory.
3952 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3953 dbxread now uses bfd for everything but symbol reading itself.
3954 BFD internals are used to drag out the relevant file offsets.
3955 (partial_symbol_file_open): Change args all around for BFD.
3957 * symtab.c: Rename "value" to "val" everywhere, so we can
3959 (symbol_file_command): New command, moved from dbxread.c
3960 and coffread.c. It uses BFD to read the file, then vectors
3961 based on its type, to dbx or coff symbol readers.
3962 * symtab.h: Extern a few vars for symbol_file_command.
3964 * target.h: Breakpoint takes a char * save area, not a char **.
3966 * valprint.c (val_print): When unpacking bitfields, offset
3967 the address in gdb of the value, if it is declared with a shorter
3968 type. Remove the last "runtime kludge test" of host byte order.
3970 * utils.c: Remove old my_bfd_read routine.
3972 * stack.c (frame_info): Use target_has_stack. Print program counter
3973 register's actual name rather than "pc", since it's called the
3974 "ip" (instruction pointer) on the i960 (sigh).
3976 * target.c (target_command): Add command for selecting a target
3977 type and calling its open routine. This is used for initiating
3978 communication with a particular target, in a generic way.
3980 * tm-i960.h: Update for modern gdb. Remove semicolons from
3981 various macros. Handle reading struct return convention, and
3982 error-out attempts to return structs with the "return" command.
3983 Be sure gdb doesn't think we know how to call functions in the
3986 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
3987 to i960_xxx in lower case.
3988 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
3989 not being defined yet.
3991 * remote.c (remote_open): Call start_remote to initialize
3992 wait_for_inferior during open.
3993 (remote_xfer_inferior_memory): Return length written rather
3996 * remote-vx.c (target_command -> vx_open): Use new generic
3998 * remote-eb.c, inftarg.c, exec.c: ditto.
4000 * infrun.c: Fix comments.
4001 (attach_program -> child_open): Use new generic target command.
4002 (wait_for_inferior): Clear saved register values before target_wait,
4003 so target_wait can set some of them if convenient.
4005 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4006 Return success indicator, not void.
4007 (child_xfer_memory): Avoid fetching initial word if we'll
4008 overwrite it anyway.
4010 * infcmd.c (attach_command): Use new generic target open routine.
4011 (_initialize_infcmd): Update doc on attach and detach commands.
4012 (do_registers_info): Merge in a byte-order problem as a FIXME
4015 * findvar.c (find_saved_register): Avoid problem in current frame.
4016 (read_relative_register): Ditto.
4017 (write_register): Convert byte order on the way out.
4019 * exec.c (file_command): Add.
4020 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4021 (xfer_memory): Common function between core_xfer_memory and
4023 (exec_xfer_memory): Use it.
4025 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4027 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4028 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4029 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4031 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4033 Merge Intel 960 port of gdb, continuing...
4035 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4036 symbol_file_command): Pass from_tty arg to hush 'em up.
4038 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4039 Add magic numbers for 960 COFF format.
4041 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4043 Merge Intel 960 port of gdb, from Intel "1.2" release.
4045 CHANGE_LOG entries from their port, which was based on
4048 Thu Sep 6 11:02:22 PDT 1990
4049 Remove temp file if download is interrupted.
4051 Wed Aug 1 09:08:33 PDT 1990
4052 Now uses binary protocol to talk to NINDY.
4053 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4054 Times out after 5 seconds when trying to talk to NINDY.
4056 Tue May 29 12:54:49 PDT 1990
4057 Added variable baud rate (-b switch).
4058 Source code reorganization.
4060 Thu Apr 26 11:09:55 PDT 1990
4061 More cleanup of batch mode; specifically, execute "-s", "-e", and
4062 "-se" switches as soon as they are encountered on the invocation line.
4064 Fri Apr 20 13:47:15 PDT 1990
4067 Thu Apr 19 09:54:28 PDT 1990
4068 Add 'reset' command.
4070 Wed Apr 18 09:48:07 PDT 1990
4071 After opening remote tty, wait for 1 second to go by without input
4072 from it before trying to talk to NINDY (fixes problems with the
4073 Heurikon HK80/V960E).
4075 Mon Apr 4 16:33:05 PDT 1990
4076 Some output was not being suppressed in 'batch' mode.
4078 Thu Mar 22 15:31:11 PST 1990
4079 Ask user if old symbol table should be deleted when new file is
4082 Allow user to run a program downloaded before gdb960 was brought up.
4084 Correct "exec-file" help message for i80960 context.
4086 Correct bug in calculating user space address: could occasionally
4087 corrupt user program.
4089 Make sure to zero low-order bits in rip's because of bug in 960CA
4090 A-step part: could cause operation faults when "next"ing across
4093 Correct bug that made it impossible to get source line numbers for
4094 code loaded at addresses higher than 0x7fffffff.
4096 Wed Jan 10 12:43:22 PST 1990
4097 Open remote tty for exclusive use.
4099 Fri Jan 5 12:14:42 PST 1990
4100 Correct disassembly (CA manual was right after all):
4101 opcode for sysctl is 0x659
4103 Mon Oct 23 12:03:04 PDT 1989
4104 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4106 Mon Oct 16 14:15:09 PDT 1989
4107 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4109 Mon Oct 2 15:56:31 PDT 1989
4111 Added 960CA disassembly support.
4113 To simplify maintenance:
4114 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4116 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4117 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4118 - made disassembly interface identical to that in gdmp960.
4122 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4124 * target.h: Allow targets to stack. Add target_has_memory,
4125 _registers, etc. Restructure memory access and "info files"
4126 to walk the target stack.
4127 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4128 target.c: Change tables to match target.h.
4129 * inflow.c (child_mourn_inferior): pop child_ops.
4130 (generic_mourn_inferior): Use new has_stack flag.
4131 * infptrace.c (child_xfer_memory): New memory regime.
4132 * inftarg.c (child_files_info): New "info files" regime.
4133 * remote-eb.c: New memory regime, new info files.
4134 * remote-vx.c: New memory regime, new info files. Now use
4135 separate targets for VxWorks attachment to machine, and
4136 actually running a process under VxWorks, since one has
4137 stack & execution & regs and the other doesn't.
4138 * remote.c: New memory regime, new info files.
4139 * sparc-xdep.c (fetch_core-registers): New memory regime.
4140 * target.c: New routines and support for stacked targets,
4141 new memory regime, new info files regime.
4144 Generalize section handling for an arbitrary number of sections,
4145 including use of the new BFD (binary file) library.
4146 * gdbcore.h: Add struct section_table.
4147 * exec.c (build_section_table): Iterate all sections and
4148 record what gdb needs to know about them.
4149 (exec_command): Use it.
4150 (exec_xfer_memory): Use the table.
4151 (exec_files_info): Print the table.
4152 * core.c (core_file_command, core_xfer_memory, core_files_info):
4154 * source.c (find_source_lines): Use bfd_get_mtime.
4155 * dbxread.c: Quick changes to make it compile with new BFD.
4156 * utils.c (error): Avoid using bfd_error in generic routines.
4158 * core.c (core_fetch_registers): Get from the ".regs" section of
4160 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4162 * inferior.h (attach_flag): Export.
4163 * infcmd.c (run_command): use new target_create_inferior.
4164 * infrun.c (child_create_inferior): Don't return result.
4165 * Makefile.dist (VERSION): 3.91.4.
4167 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4169 * breakpoint.c (bpstat_num): Handle breakpoints which have
4170 since been deleted, such as temporary breakpoints.
4171 infcmd.c (program_info): ditto.
4173 * core.c (core_file_command): Display the frame where the core
4178 * remote-vx.c (target_command): Merge in target command from
4179 targ-vx.c. A few other cleanups.
4181 * TODO, Projects: Lots more stuff to do...
4183 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4185 Massive changes to wall off the remote-debugging interface
4186 behind a function vector. The port to handle VxWorks targets
4187 is also part of this.
4189 All files: Replace references to renamed functions,
4190 remove references to remote_debugging, remove references to
4191 have_include_file, have_core_file in favor of target_has_stack,
4192 target_has_memory, etc.
4194 * Modularize the breakpoint interface.
4195 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4196 a breakpoint instruction.
4197 breakpoint.c: struct breakpoint's shadow_contents now sized as
4199 (insert_breakpoints): Vector to target to install breakpoints.
4200 (remove_breakpoints): Vector to target here too.
4201 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4202 sparc-tdep.c (single_step): Use new breakpoint interface for
4203 the single-step breakpoints.
4204 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4205 New file, contains routines to insert and remove breakpoints by
4206 reading out the old contents and later replacing them. This is
4207 how ptrace breakpoints work, and many remote systems as well.
4209 * tm-vxworks68.h: New config file, overrides a few things for
4210 Wind River's preferences.
4212 * target.h: New file, for transfer vector used to talk to the
4213 inferior (child, attached, core, exec, remote, etc). All accesses
4214 to the thing being debugged should come through these vectors.
4215 target.c: New file, routines to handle transfer vector.
4216 (various files): Add transfer vectors XXX_ops for the various
4217 targets and pseudo-targets (core files, etc) we support.
4219 * breakpoint.c (bpstat_stop_status): Further explorations of
4220 watchpoints and why things don't work all the time.
4221 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4223 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4224 the local gdbinit if it doesn't already have it.
4226 * core.c (core_ops): add and install.
4227 Allow core debugging without exec file.
4229 * dbxread.c (free_and_init_header_files): Merge two fns.
4230 (end_symtab): Free named symbol table when a new version comes in.
4231 (read_dbx_symtab): Relocate all kinds of symbols with base
4232 address. First step toward handling different text, data, bss
4234 (add_file_addr_command): Renamed add_file_command.
4235 (add_file_command): Vector to remote handler.
4236 Add "load" as an alias for "add-file" command.
4238 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4239 non-returning functions.
4241 * exec.c: Add exec_ops, and push it as a target when an exec
4244 * infcmd.c (run_command): Pass executable file name and arg list
4245 separately when starting an inferior. Permit "run" when no exec
4246 file is specified, for VxWorks.
4247 (detach_command): Move to child_detach in inftarg.c.
4249 * inftarg.c: New file. Unix-child-specific routines, and the
4250 child_ops structure.
4252 * inferior.h (registers): Export "registers" as the way for
4253 target dependent register handlers to find gdb's local copy of
4254 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4255 since it is now used by places that want wait_for_inferior to
4256 handle the grunge but want to see every trap from the inferior.
4258 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4259 Eliminate remote_debugging hooks in terminal handling.
4261 * infrun.c: Replace start_inferior with child_create_inferior.
4262 Move all the hair of Unix shells and ptrace idiosyncracies into
4263 child_create_inferior, so remote handlers don't have to deal.
4264 Remove running_in_shell. Rename stop_after_attach to
4265 stop_soon_quietly, and use it in a few other places where we want
4266 to just call wait_for_inferior and get control back on the first
4267 trap. trap_expected now never takes a value > 1.
4268 (init_wait_for_inferior): Initialize static vars when a new
4271 main.c (gdbinit): Add new hook for .gdbinit file name, let
4272 it be overridden by config files as GDBINIT_FILENAME.
4273 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4274 Both of these are used for VxWorks gdb.
4276 mcheck.c: rename include file "gmalloc.c" to avoid problems
4277 with system include file "malloc.c".
4279 param-no-tm.h: New include file, same as param.h but does not
4280 include the default "tm.h" file. This is used in files where
4281 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4283 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4285 remote-vx.c: New file, VxWorks remote debugging support. Uses
4286 RPC routines that are shared with the target system, in directory
4289 remote.c: Vectorize remote interface.
4291 source.c: Globalize source_path, and make an alias "l" for "list"
4292 since we now have the "load" command.
4294 sparc-xdep.c: Use new param-no-tm.h.
4296 symmisc.c (free_named_symtab): Add new function from Wind River.
4297 However, ifdef it out for now while we think about what it should
4300 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4302 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4303 non-Unix-children handle this with their own code in the target
4306 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4307 source and target lists. Add vx-share to default list of include
4308 directories. Add new files to src and target lists: mem-break,
4309 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4310 ${srcdir} versions of munch and createtags are used.
4312 * valops.c (find_function_addr): Split out of call_function.
4313 (call_function_by_hand): Rename call_function; this function
4314 calls functions in the target by laboriously patching the target
4315 word-by-word with the right stack, args, regs, etc.
4318 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4320 Handle AMD 29000 a bit better.
4322 * remote-eb.c (readchar): Mask received char log to make it readable.
4323 (remote_start): Pass arguments down to executing program.
4324 Make startaddr unsigned.
4325 infrun.c (start_inferior): Accept args, pass them to
4327 infcmd.c (run_command): Pass args down to start_inferior.
4329 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4330 the target object file format.
4331 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4333 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4334 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4336 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4338 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4339 * TODO: We did a few things, we have more to do though.
4341 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4342 * inflow.c (inferior_died): Clear deferred stores.
4344 * Debug problems with dummy frames and calls to the inferior.
4345 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4346 * sparc-tdep.c (do_restore_insn): Simplify.
4347 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4348 (sparc_push_dummy_frame): Simplify and fix what we push.
4349 (sparc_pop_frame): Slightly more hair here, deciding whether
4350 we are restoring a saved PC or returning to a return address in %i7.
4351 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4353 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4354 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4355 * obstack.h (chunkfun): ditto.
4356 * defs.h (xmalloc, xrealloc): ditto
4358 * utils.c (quit): Grab the terminal from the child if necessary.
4360 * inflow.c (term_status_command): Rename to term_info, change
4363 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4364 (is_delayed_branch): Speed up.
4365 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4366 Still missing some float ops, and needs testing.
4368 * Support for input and output radixes other than base 10
4369 * defs.h (input_radix, output_radix): Declare.
4370 * expread.y (yyparse, parse_number): Handle changes of input
4371 radix, and ambiguous names-or-numbers in radixes >10.
4372 * printcmd.c (print_scalar_formatted): Print formatted hex
4373 numbers in varying column widths.
4374 * valprint.c (val_print): Use output_format to print scalar ints.
4375 (set_input_radix, set_output_radix, set_radix): Create.
4376 (set_output_radix): Set output_format from output_radix.
4377 (_initialize_valprint): add `set radix' but leave the others off.
4379 * main.c (execute_command): Let stupid questions be turned off.
4380 (_initialize_main): Handle "set stupidity", etc.
4382 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4383 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4385 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4387 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4388 bfd stuff is still screwed up, but with some manual work, it
4391 * breakpoint.c (bpstat_do_actions): Start over if a command
4392 proceeds the inferior, since the inferior will have stopped and
4393 will need to have its new stop-actions taken care of.
4395 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4396 compiler fits, simplify it.
4398 * gdb.texinfo (directory command): Doc new dir command.
4399 source.c (directory_command): "dir" now puts things on the front
4400 of the path, moves dups up front, and handles multiple names
4401 on the command line, inserting each one in order. It also
4402 blows away cached line and full_filename info.
4404 * stack.c (backtrace_command): Skip "more stack frames follow"
4407 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4408 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4409 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4410 The only odd one was Gould NP1, which had defined vprintf to
4413 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4414 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4415 variable, inspect_it.
4416 valprint.c (print_string, val_print): Use the global inspect_it
4417 to indicate whether to print in Epoch style or normal style.
4419 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4421 * printcmd.c (call_command): add an alias for the "print" command
4422 which runs expressions and doesn't print the result if void.
4423 (print_command_1): implement it.
4425 * command.c: Remove #if 0'd code. Initialize all the fields
4426 in add_cmd (). Rename do_nothing_command to
4427 not_just_help_class_command, and make it externally visible.
4428 command.h: add user_commands to struct.
4429 * main.c (define_command): Don't overload c->function with a char
4430 string as well as a function pointer.
4432 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4433 calling convention of value_struct_elt () that got dropped in
4436 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4437 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4439 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4441 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4442 until a good time (e.g. when we are about to run the child),
4443 saving ptrace calls.
4444 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4445 * tm-sparc.h: define DO_DEFERRED_STORES.
4447 * sparc-xdep.c (store_inferior_registers): when storing float
4448 registers, don't store stack regs too. When storing the SP,
4449 however, DO store the stack regs too. This fixes a bug in which
4450 the dummy frame is not recognized when a call_function finishes,
4451 because its frame pointer (in the stack regs) was never
4453 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4454 even though we don't know how to read them from an inferior.
4455 valops.c (call_function): Comment about storing SP.
4457 * infrun.c (save_inferior_status): Save away the original bpstat
4458 chain so it can be restored later. Install the copied version for
4459 use by whoever saved the status. It will be blow away by
4460 restore_inferior_status, and the original chain restored. This is
4461 important for people who have pointers into the original.
4463 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4464 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4465 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4468 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4470 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4471 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4472 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4474 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4476 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4477 Store the baseclasses in a type struct starting from array element
4478 0 rather than from the unusual array element 1.
4480 dbxread.c: the above.
4481 (virtual_context): Add
4482 Read new debug information about which virtual function table
4483 a virtual function is from, and store it in fn_field.fcontext.
4485 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4486 TYPE_FN_FIELD_STATIC_P.
4488 symtab.c: the above.
4489 valops.c: the above. Handle pointer casts of object *'s.
4490 (search_struct_method): Add.
4491 (value_struct_elt): First arg is now a pointer to a value, and is
4494 valprint.c: the above.
4495 values.c (value_virtual_fn_field): Add type arg. Handle
4496 offsetting to the proper object when calling virtual fns.
4498 (baseclass_addr): Add valuep arg.
4500 * README: Document the current state of BFD config (missing).
4501 * TODO, ChangeLog, Makefile.dist: Roll version.
4502 * WHATS.NEW: Add summary of changes since 3.5.
4504 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4506 * dbxread.c (read_struct_type): Clear bit vectors whenever
4508 symtab.c (B_CLRALL): define.
4510 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4511 using == rather than =. Huh... This fixes the dreaded problem
4512 wherein builtin_type_int becomes TYPE_CODE_FLT.
4514 * core.c (info_files): Show the inferior pid.
4516 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4517 already knows how to look in the source directory.
4519 * Remove psymtab hair from many places. Remove duplicated code
4520 for searching symbol tables. Hide psymtabs from most places.
4521 Make it fast to get from a psymtab to its symtab.
4523 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4524 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4525 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4526 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4527 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4528 new symtab completely. New psymtabs get symtab pointer
4529 initialized to zero. Remove MI warning printf.
4530 symtab.h: Comments. Add psymtab to symtab pointer.
4531 (PSYMTAB_TO_SYMTAB): New macro.
4532 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4533 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4535 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4537 (print_frame_info): Avoid special-casing symbols that have not yet
4540 * source.c (open_source_file): Quick path if we have already
4541 located the source file by its full name.
4543 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4544 find_pc_psymtab. When a name is found in the misc function
4545 vector, search the symbol table for its mangled name, not the
4546 name that the user typed.
4548 * bfd.h: Fix missing comment terminators, make #endifs match.
4550 * valarith.c (value_less): Handle unsigned int comparisons.
4551 Add FIXME about pointer compares, which assume host and target
4552 pointers are the same.
4554 * command.c (do_nothing_command): lint
4555 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4556 fix comments on debug symbol format for visibility. Actually set
4557 visibility of symbols.
4558 main.c (echo_command): lint; use <readline/history.h>.
4559 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4560 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4561 pointing past end of allocated memory; saber complains.
4562 obstack.h: Declare the external functions that we use.
4563 valarith.h: use <string.h>
4564 solib.c (solib_add): lint.
4566 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4568 * main.c (initialize_main): Default info_verbose to off, now that
4569 symbol reading is fast.
4570 (quit_command): Avoid clobbering exec_bfd while quitting.
4572 * Initial BFD (binary file diddling library) merger:
4573 coffread.c: Change AOUTHDR to struct exe_hdr.
4575 core.c: initialize initialized data at compile time.
4576 (core_file_command): Move from coredep.c, convert to bfd.
4577 (xfer_core_file): Convert to bfd.
4578 exec.c (exec_file_command): use bfd routines.
4580 mips-tdep.c: Remove exec_file_command and friends.
4583 * coredep.c: (fetch_core_registers) Convert core_file_command to
4584 fetch_core_registers.
4585 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4587 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4588 (my_bfd_read): More bogosity, which I don't think we call.
4589 (program_name): Remove this atrocity asap!
4591 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4594 values.c: allocate_repeat_value was not clearing the
4595 optimized_out field.
4596 (value_static_field): minor stylistic fix (wrong macro was used).
4597 valops.c (value_struct_elt_for_address): didn't work for C++
4600 * signame.c (_initialize_signame): Initialize signal names once.
4602 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4603 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4604 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4606 * remote-eb.c: Support user-settable baud rates on the serial port.
4608 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4610 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4612 * tconfig/sun3os4: Remove warning about native assembler,
4613 since it also occurs in the xconfig file.
4615 * findvar.c (registers): Allocate some slop after `registers'
4616 to prevent stray accesses from trashing the next variable.
4618 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4619 on the sun-3, by changing the #ifdef from `sun3' (which is not
4620 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4621 vars, which happened to follow `registers' in the executable.
4623 * readline/history.c (history_search): Heed gcc-2's advice
4624 and parenthesize && inside ||).
4626 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4627 tm-29k.c: Insert FSF copyright headers.
4629 * remote-eb.c: Better comments.
4631 * Makefile.dist: Update to 3.91.6.
4632 * TODO: note PREPARE_TO_STORE problem.
4634 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4636 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4638 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4640 * infrun.c (wait_for_inferior, at end): Don't set up
4641 prev_* if the inferior no longer exists.
4643 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4644 CANNOT_EXECUTE_STACK.
4645 valops.c (call_function): Use it.
4647 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4649 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4650 infrun.c (wait_for_inferior, 2 places): Use it.
4652 * values.c (value_being_returned): Only use
4653 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4655 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4656 right thing for remote-eb.c.
4658 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4659 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4661 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4662 (FRAME_FIND_SAVED_REGS).
4664 * findvar.c ({fetch,store}_registers): Check for
4665 REMOTE_{FETCH_STORE}_REGISTER macro.
4667 * findvar.c (get_saved_register): Add argument lval and
4668 change meaning of argument addr.
4669 findvar.c: Change calls to get_saved_register to reflect
4670 new calling convention.
4671 valops.c (value_assign): Use get_saved_register instead of
4672 find_saved_register.
4674 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4676 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4677 an (uninitialized) pointer to one. Use "&" when passing it
4680 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4682 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4685 * coffread.c (symbol_file_command): Put semicolon after
4687 Put safe_to_init_tdesc_context in #if defined (TDESC).
4688 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4689 coffread.c: #include <sys/stat.h>.
4690 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4691 Add missing ')' in check for "lc%" and friends. Remove
4693 Declare read_one_sym() at top of file.
4694 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4695 MC68WRMAGIC can have the same value without causing a duplicate
4698 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4700 * Allow a Makefile to be built without building the
4701 tm and xm file links that screw up builds in subdirectories.
4702 This is done with `config.gdb none', then you can do things
4703 like `make gdb.tar.Z'.
4704 * tconfig/none: Config file for no target system
4705 * xconfig/none: Config file for no host system
4706 * config.gdb: If no TM or XM files are called out by the
4707 host or target file, don't make links for them.
4709 * cplus-dem.c: Add documentation.
4711 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4712 simple error, so the user's gdb doesn't crash due to some object
4713 file problem (e.g. somebody is rebuilding the file out from under
4716 * printcmd.c (print_address_symbolic): demangle the symbol.
4718 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4719 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4720 (alldeps.mak): sort and uniq all results from this; duplicates
4721 hose gdb.tar.Z link building. Remove RCS files from
4722 tconfig and xconfig. Add config files for sun386. Add
4723 a few odd files to OTHERS and HFILES.
4725 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4727 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4728 Roll version number to 3.91.5. Make lint work in bindir.
4730 * README: Document cross-debugging and new file structure.
4732 * blockframe.c: Lint. Include "value.h" to declare read_register.
4733 (find_pc_partial_function): remove duplicate line.
4735 * command.h: Lint. Declare error_no_arg and dont_repeat.
4737 * tm-news.h: Remove inadvertently duplicated stuff.
4739 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4740 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4742 * config.gdb: Allow `config.gdb host target' form. Clean
4743 up previous change that printed bogus messages when you just said
4746 * core.c: #include "command.h" for lint.
4749 * main.c: Remove some casts of enums. Lint.
4756 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4758 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4759 read it from memory. This will allow us to save ptrace calls
4760 eventually. Changed caller single_step too.
4762 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4763 that we aren't going to use, saving many ptrace calls, especially
4764 when watchpointing or single stepping. Use some #define's for
4766 (store_inferior_registers): Ditto.
4767 (core_file_command): Use some #define's for constants.
4769 * tm-sparc.h: Add #define's for some register numbers, so we
4770 can eliminate the use of random constants in sparc-xdep.c.
4772 * stack.c (frame_command, print_frame_info, up_command,
4773 down_command) Remove frame_changed, since it
4774 causes a bug and doesn't seem to do anything useful. In some
4775 places it was used as a flag, in others as a stack level (?).
4777 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4778 default is to use the portable (vprintf) version rather than the
4780 * xm-news.h (MISSING_VPRINTF): Add.
4782 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4784 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4786 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4787 about linking debugged programs -Bstatic in the sun?os4 config
4788 files in tconfig and xconfig subdirectories.
4790 * main.c (main): Remove unreached exit(0) now that we exit
4793 * Create TODO file for online bug list. There are too many
4794 "little" bugs to keep track of on paper.
4796 * Change Projects file to refer to bug-gdb@cygnus.com
4797 rather than kingdon@ai.
4799 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4801 * Makefile.dist (VERSION): 3.91.4 now.
4803 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4804 (condense_misc_bunches): Add sanity check that misc_count is
4805 the same as the number of symbols in the bunch.
4807 * coffread.c: rename init_misc_bunches. Pass an argument
4808 to condense_misc_bunches (a zero).
4810 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4811 every time we are called; don't rely on our caller to do it.
4812 (add_file): Remove call to init_misc_bunches.
4814 * mipsread.c: Only warn, don't error, if unknown symbol types.
4815 This keeps an old gdb from falling on its face if it sees newly
4816 extended symbol info. Rename init_misc_bunches.
4818 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4820 * Merge in changes from Per Bothner for DECstations and other
4821 MIPS stuff. The rest is Bothner speaking:
4823 The next message is a merger of Alessando Forin's mips port with
4824 mine. I've tried to use my good if biased judgment to get
4825 the best of both. It *does* need testing.
4827 Some of the changes are general, *not* mips-specific.
4830 Didn't believe in little-endian bit order.
4831 There are still inconsistencies about whether flags
4832 like BITS_BIG_ENDIAN are integer (#if ...) or
4833 boolean (#ifdef ...). I tried to paper over them.
4835 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4836 Moved some misc_function code that was common to
4837 {dbx,coff,mips}read.c to symtab.c.
4838 In the process, I think I cleaned things up a bit.
4839 At the same time, moved obsavestring and obconcat to symtab.c.
4842 Removed obsolete condense_addl_misc_bunches (use
4843 condense_misc_bunches(1) instead).
4846 Needed to include <sys/dir>, at least on DECstations.
4848 valops.c, mips-tdep.c, tm-mips.h:
4849 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4850 conventions (when STACK_ALIGN is insufficient).
4851 Needed on mips, where doubles need 8-byte alignment,
4852 but ints only need 4.
4855 Removed cruft that was not being used.
4856 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4859 Print $ before register-names (I think that makes things a little
4861 Never print two instructions, even if one delays.
4862 Removed hex-disassemble set_cmd. (This is not mips-specific,
4863 so I think the argument is whether it is generally worthwhile or not.
4864 I'm inclined to think not, given how easy it is to
4865 convert between radixes in gdb.)
4868 This is basically Alessando's code.
4869 It doesn't use obstacks; I changed it to use obstacks
4870 in a few minor places where using malloc causes a
4871 memory leak. (Probably, more places could/should be changed.)
4872 I added record_misc_function where it was missing.
4873 In symbol_file_command and add_file_command, I tried
4874 to make the code consistent with more recent versions.
4875 Minor sylistic changes in parse_procedure.
4876 Make a .gdbinfo. psuedo-symbol point back to the real
4877 procedure symbol (using the isym field).
4880 This is basically from my port, but with a lot of details
4881 and a number of routines merged in from Alessando's version.
4882 I basically used my code "raw" backtrace (use heuristics
4883 from the actual code, rather than symbol table info) - though
4884 the idea is Alessandro's. I feel my code is a little cleaner
4885 here, particularly in being a little more flexible, such as being
4886 able to handle gcc-produced code (which it now can).
4887 It also doesn't do frame caching (which is not useful
4888 more recent gdb versions).
4889 I also used my code for push_/pop_dummy, more or less.
4890 I tried to incorporate AF's code for testing sigtramp
4891 while backtracing; I probably got it wrong.
4892 Added mips_print_register, which tries to scrunch as much
4893 information as possible on a screen...
4894 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4895 under mips-pinsn.c), I don't see anything mips-specific here,
4896 and I don't see it being all that useful anyway.
4899 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4900 Use more register names (rather than hard-cases numbers).
4902 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4904 * Hack up 3.90.11 changes:
4906 * Makefile.dist (depend): parameterize $(GCC).
4907 Add solib.c and solib.o.
4908 (readline): Fix vpath for both absolute or relative SRCDIR.
4910 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4911 Also, let the part I didn't understand at least compile so
4912 I can test the rest. FIXME.
4914 * dbxread.c: Fix thinko using strcmp.
4915 (init_psymbol_list): declare static.
4916 (partial_symbol_file_open): Comment cleanups better, avoid
4917 cleaning up the string table since the caller will do that.
4918 Move the stat for mod time into symbol_file_command, temporarily.
4919 (There should be a mod time for each symbol file, eventually,
4920 to control its rereading. FIXME.)
4922 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4923 SunOS, which gives error for shared libs otherwise. (From
4924 Schaefer, probably FIXME needs work for portability.)
4926 * solib.c: Move #include "param.h" to work.
4927 Lowercase all the Uppercase Letters In the Messages.
4928 (find_solib): Clean up inferior_so_name for debug printouts.
4929 Allow no argument, to mean all shared libraries.
4931 * symmisc.c: include param.h to get CLEAR_SOLIB.
4933 Wed Sep 5 18:00:08 1990 John Gilmore (gnu at cygint)
4935 * Merge in Kingdon's changes from FSF: the diffs from 3.90.9
4936 to 3.90.11. ChangeLog entries below are from this.
4938 Wed Jun 13 09:17:39 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4942 * Makefile.dist (HFILES): Add tm-sunos.h.
4944 Tue Jun 12 16:15:26 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4948 * Makefile.dist (gdb.tar.Z): Change linking of config so it works.
4950 Thu Jun 7 16:22:27 EDT 1990 Jay Fenlason (hack@ai.mit.edu)
4952 * sparc-opcode.h Added single-operand version of rett.
4954 Mon Jun 4 18:12:31 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4956 * m-sparc.h (REG_STRUCT_HAS_ADDR, STRUCT_ARG_SYM_GARBAGE):
4957 Put parens around gcc_p in expansion.
4959 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4961 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4963 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4965 * Changes for Sun shared libraries:
4966 blockframe.c (find_pc_partial_function): If a non-text symbol
4967 is found, set *address = pc - FUNCTION_START_OFFSET.
4968 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4969 Disable breakpoints instead of giving an error.
4970 source.c (select_source_symtab): Initialize cs_pst.
4971 symmisc.c: Call CLEAR_SOLIB if defined.
4972 symtab.h: Make text{low,high} CORE_ADDR not int.
4973 (psymtab): New field addr.
4975 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4976 (record_misc_function): Give correct type for N_DATA symbols.
4977 (condense_misc_bunches): do "misc_function_count = j" regardless
4979 Take code which is shared between symbol_file_command and
4980 add_file_command and put it into partial_symbol_file_{open,read}.
4981 Split add_file_command into add_file_command and add_file.
4982 Make psymtab_to_symtab read in the string table if the file
4984 Two new parameters to read_dbx_symtab and start_psymtab.
4985 tm-sunos.h: New file.
4987 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4989 * infcmd.c: Change cont_command to continue_command and "cont"
4992 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4994 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
4996 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
4998 * values.c (USE_STRUCT_CONVENTION): Check for structures of
4999 size 1,2,4,8 rather than size < 8.
5001 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5002 as necessary, not just once.
5004 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5006 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5008 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5010 * tm-news.h: Add CALL_DUMMY_*.
5012 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5014 * config.gdb: In list_host, list_target, use ${i}, not $i.
5016 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5018 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5020 * sparc-opcode.h: Change all store floating-point state register
5021 instructions to have the right match & lose fields.
5023 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5025 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5027 config.gdb: If srcdir != ., create readline directory and
5028 copy a makefile into it.
5030 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5031 consistency with POSIX.
5033 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5034 when we exit its exp_valid_block.
5036 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5038 * Makefile.dist: Bump version to 3.91.3.
5040 * Clean up handling of breakpoint commands (somewhat).
5041 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5043 inferior.h: Add breakpoint_proceeded to inferior status struct
5044 and globals; save it and restore it.
5045 (clear_breakpoint_commands): Cleanup, remove old #define.
5047 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5048 (save_inferior_status, restore_inferior_status): handle it also.
5049 (proceed): Remove earlier code that set breakpoint_proceeded.
5050 It is now set only in clear_proceed_status.
5051 (clear_proceed_status): Cleanup, use bpstat_clear rather
5052 than clear_breakpoint_commands. No callers need the stop_bpstat
5053 between clear_proceed_status and proceed.
5055 infcmd.c: Add breakpoint_proceeded definition and comment.
5056 (cont_command, jump_command, signal_command): Move call to
5057 clear_proceed_status right next to call to proceed.
5059 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5060 caller's argument while running down the chain of breakpoints.
5061 Use new variable "breakpoint_proceeded" to determine when
5062 a command that it executes moves the inferior past the
5064 (bpstat_clear): Handle NULL argument.
5065 (bpstat_clear_actions): Avoid useless call to
5066 breakpoint_auto_delete.
5067 (delete_breakpoint): Clean up bpstat's that are pointing to
5068 the deleted breakpoint from the stop_bpstat chain.
5069 (breakpoint_auto_delete): Simplify.
5071 * Clean up handling of EOF, error on stdin, etc. This was
5072 prompted by a network problem that caused gdb to go into an
5073 infinite loop filling up its malloc'd memory.
5075 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5076 not clear_breakpoints_commands, which is now gone.
5077 (main): If command_loop returns (e.g. from EOF on stdin), do
5078 a quit_command (looping back to command_loop if quit_command
5079 doesn't really quit).
5080 (command_loop): check result from command_line_input and
5081 exit if it returns NULL, rather than passing the NULL to
5083 (gdb_readline): Free malloc'd result space before returning
5086 * utils.c (query): Handle C-d to mean "yes", just as if the
5087 input was not a terminal. Also avoid infinite loop if EOF
5088 occurs in mid-input-line before newline. This allows
5089 query to be used at EOF on stdin with reasonable results.
5091 * infrun.c (proceed): Set breakpoint_proceeded.
5093 * values.c (value_as_long): Avoid infinite recursion for enums.
5094 (_initialize_values): Fix typo in help msg (kingdon).
5096 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5097 RL_LIB for linking. This allows -lreadline for linking
5098 and nothing for dependencies, once readline is a real library.
5100 * config.gdb: Jim Kingdon: give useful error message if the
5101 host or target type is not recognized.
5103 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5104 it just defines it. Dumb, but deal with it.
5106 * Jim Kingdon suggests:
5107 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5109 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5111 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5113 * Clean up Bothner's changes.
5115 * blockframe.c (clear_pc_function_cache): New function.
5116 * blockframe.c: remake cache_pc_function_* static.
5117 * dbxread.c (symbol_file_command): remove references to
5118 cache_pc_function_* variables.
5119 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5120 * printcmd.c: Avoid kludging a global variable (addressprint)
5121 to avoid printing the address of a string twice. Instead,
5122 pass the format letter 's' down low enough that it can be seen
5123 to avoid this problem.
5124 (print_formatted): Pass format arg to value_print.
5125 (restore_addressprint): Remove function.
5126 (do_examine): Avoid hacking addressprint, cleanups and such.
5127 (print_frame_args): Add a comment to a Bothner change.
5128 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5129 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5130 to wipe out the values cached in blockframe.c.
5131 * symtab.c (find_method): Add comment saying how big you must
5132 allocate to be "big enough". Per being terse again.
5133 * valprint.c (val_print): Handle format letter "s" to print
5134 strings without addresses. Add comment to vtbl printing code
5135 which casts with wild abandon. Rearrange reference-printing
5137 @0xaddr: value (print w/addressprint)
5138 value (print w/~addressprint)
5139 @0xaddr (parameter lists w/addressprint)
5140 or nothing (parameter lists w/o addressprint)
5142 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5144 * Merge more changes from Per Bothner:
5146 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5147 annoying) that I tried to improve it. Here are my suggestions.
5149 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5152 Do automatic de-reference when taking the address of a reference.
5154 Don't deref_ref when printing parameter lists.
5156 More attempts at treating refernences properly.
5158 In val_print, if deref_ref==0, don't print dangling " = ".
5160 Add COERCE_REF macro, which de-references an REF.
5162 * Merge changes from Per Bothner:
5164 * Fixed (Sony news)-specific configuration problems.
5165 * Fixed other problems with using vanilla pcc and libc (enum problems;
5166 assumption that vsprintf exists).
5167 * Some major speed-ups (finc_pc_partial_function now caches a match;
5168 parsing avoids duplicate symbol_lookup calls).
5169 * Changed handling of baseclasses (no longer use baseclasses field
5170 of struct type, use the first n_baseclasses fields instead).
5171 * Various minor changes/fixes, most C++-related.
5174 Cache the most previous match from find_pc_partial_function.
5175 (Save both low and high ends of matching function's pc range.)
5176 This speeds up the loop of infrun.c:wait_for_inferior quite
5177 a bit, and makes step/next commands much zippier.
5179 Added an enum->int cast (otherwise, some compilers barf).
5181 No longer set baseclass offset to 0, since multiple
5182 inheritance now mostly works.
5183 Added a number of casts, to shut up compiler warnings
5184 (after stabs where made enums, not ints).
5185 When discarding a symbol table (in symbol_file_command),
5186 must clear the cache introduced in blockframe.c.
5187 Don't convert $vtbl_ptr_type to vtbl any more.
5188 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5189 Mask off sign bit emitted by g++ for virtual table offset.
5190 Set voffset to -1 (not 1) for static member functions.
5192 Changed parsing/lexing of names to avoid doing symbol lookup twice
5193 (once when lexing to determine symbol class, once for real).
5194 Now only call symbol_lookup once. Fields of 'this' win especially big.
5196 Subpress printing addr twice in the case of 'x/s addr'.
5198 lookup_basetype_type is no longer used.
5199 Add find_methods as recursive helper function to decode_line_1.
5200 This allows multiple inheritance to work.
5201 Also, once one or more matches has been found, do not look in
5202 base-classes. (Baseclass methods would be overridden, anyway.)
5204 Removed baseclasses array in struct type.
5205 Instead of using baseclasses[i], use fields[i-1].
5206 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5207 Changed sign convention of voffset (previous was inconsistent).
5209 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5211 Used to assume existence of vsprintf. Re-written to not need it
5212 if HAVE_VPRINTF is undefined.
5214 typecmp was too pessimistic. Made it less so.
5216 Don't print space after address.
5217 If vtable points to a misc symbol (with 0 offset), print it,
5218 since that indicates the actual class of the object.
5219 Changed ype_print_derivation_info to use new inheritance
5220 scheme (without baseclasses vector).
5222 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5223 Also, changes needed because TYPE_BASECLASSES were removed.
5225 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5227 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5230 If there is no path set, and the symbols don't indicate what directory
5231 a file was compiled in, look in the current directory. But either
5232 a path or a known compilation directory will prevent this.
5235 Three independent bug fixes:
5236 * Remove the #if 0 block that breaks some stuff.
5237 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5238 adapt gdb to either SunOS 4.0.* or 4.1.
5239 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5242 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5245 (type_print) Demangle the name being printed.
5246 (type_print_base) Handle botched demangling without coredump (tiemann).
5249 (check_stub_method): Document routine.
5250 (tiemann) fix bug for no-arg functions
5251 Avoid clobbering beyond end of malloc'd storage.
5252 Terminate the argument list properly.
5254 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5256 * Changes merged by John Gilmore:
5259 In breakpoint_1, use new print_address_symbolic instead
5260 of find_pc_partial_function. (This forces use of assembler-level
5261 addresses, and avoids misleading non-mangled source-level names.)
5263 Generalize ansi argument such that -1 means skip arglist totally.
5264 Removed global variable print_ansi_qualifiers (which made
5265 code non-reentrant), in favor of extra explicit arguments
5266 to internal routines.
5268 Add new helper function print_address_symbolic.
5269 Use find_pc_misc_function instead of find_pc_partial_function
5270 (since we want assembler-level symbols here).
5272 Print unknown function as just "f (...)", not "f (...) (...)".
5273 Use new fputs_demangled explicitly.
5275 Fixed a typing violation (problem: value.h cannot be imported
5276 without renaming many variable in this file).
5277 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5278 decode_line_1: Moved forward some never-reached code.
5279 Made decode_line_2 skip function prologues correctly.
5281 fputs_filtered should not demangle by default.
5282 Add new fputs_demangled to demangle on demand..
5284 Change value_struct_elt to use value_primitive_field (using recursive
5285 utility function search_struct_field). This allows foo.bar to work
5286 for multiple inheritance (so far only for data fields).
5287 Change check_field in the same way (recursive helper function
5288 to support multiple inheritance).
5289 (Note: there are more of these problems that I haven't fixed.
5290 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5291 value_of_this: 'this' symbol name is now just "this", note "$this".
5293 Don't print static members.
5294 Avoid printing "members of <type>" if there are none.
5295 Simplified type_print_derivation_info by merging duplicate code.
5296 Remove useless blank lines in type_print_base (ptype command).
5298 Added declaration of new routine value_primitive_field.
5300 Added value_primitive_field which is generalized version of
5301 value_field that can handle multiple inheritance (non-zero offsets etc).
5302 Re-implemented value_field to call value_primitive_field.
5304 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5306 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5307 delete the whole environment. Karl Berry reported the bug.
5308 * source.c - fix openp to avoid //'s in filenames, which
5309 trigger an Emacs bug causing it to not be able to find files
5310 when running gdb in a window.
5311 * dbxread.c - zap the #if 0 that botches the add-file code.
5312 It seems to work a lot better without all the code commented out.
5314 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5316 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5319 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5321 * Makefile - added a ${CFLAGS} to a couple of entries,
5322 added remote-sa.sparc.c
5323 * added remote.sa-sparc.c, a modification of remote.c
5324 which conducts a dialog directly with the SparcStation prom.
5325 * breakpoint.c, infrun.c, sparcdep.c added
5326 remote_insert_breakpoint(), and remote_remove_breakpoint()
5327 to breakpoint.c instead of directly writing breakpoint instructions.
5328 * sparcdep.c on remote_debugging,there is no need
5329 to remove signle step breakpoint instructions.
5330 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5332 * printcmd.c - epoch interface sends lisp expressions to open up
5333 epoch windows on inspection.
5334 * valprint.c - added arrayprint, and addressprint and made adding
5335 format controls easier
5336 * wait.h added a couple of undef's because we were getting
5337 complaints about WSTOPSIG and WTERMSIG begin redefined.
5340 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5342 * symtab.c (decode_line_1): Add support for handling method stubs
5343 in the type information.
5345 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5347 * values.c (baseclass_addr): Run loop from INDEX+1 to
5348 N_BASECLASSES; otherwise, we can still get into a loop.
5349 @@ This should be restructured to use a cleaner search strategy.
5351 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5353 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5354 abbreviation "Tt" for tags which have the same name as their
5357 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5359 * symtab.c (list_symbols): add ability to set breakpoints on all
5360 the functions which match a particular regular expression.
5362 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5364 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5365 should print ANSI qualifiers (such as `const' and `volatile').
5366 All callers changed to call with ANSI == 1, except from
5367 `check_method_stub', which uses old-style syntax.
5369 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5370 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5372 * values.c (check_stub_method): New function.
5374 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5376 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5377 * valprint (type_print_base): Ditto.
5379 * symtab.c (gdb_mangle_typename): New function.
5381 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5383 * breakpoint.c (catch_command): New function. Provides a
5384 mechanism to set breakpoints based on catch clauses.
5385 (disable_catch): Similar, but disables breakpoints on catch
5387 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5389 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5391 * blockframe.c (blockvector_for_pc): New function.
5392 * blockframe.c (block_for_pc): Changed to call
5393 `blockvector_for_pc' and get the block itself.
5395 * stack.c (catch_info): New function. Prints info about
5396 exceptions which can be caught in the current frame.
5397 * stack.c (print_frame_label_vars): New function. Similar to
5398 `print_frame_local_vars'.
5399 * stack.c (print_block_frame_labels): Prints out labels that are
5400 defined in this frame. These labels are exceptions that can be
5403 * dbxread.c: Updated to handle N_CATCH symtab types.
5405 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5407 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5408 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5409 when printing the type.
5411 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5413 * valprint.c (val_print): Use `baseclass_addr' to access the
5414 baseclasses pointed to via the derived class object at VALADDR.
5416 * values.c (baseclass_addr): New function. Casts derived pointers
5417 to baseclass pointers taking virtual baseclasses and multiple
5418 inheritance into account.
5420 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5424 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5426 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5427 exp_valid_block field correctly.
5429 * infrun.c (wait_for_inferior): When checking "don't even think
5430 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5431 also check step_resume_breakpoint.
5432 Insert breakpoints and continue (not step) if
5433 step_resume_break_address != NULL, even if another_trap.
5434 If trap_expected and we enter sigtramp, then set up a
5436 If trap_expected is set when we hit the step_resume_break,
5438 When calling resume and trap_expected says tell resume to step
5439 (2 places), also check step_resume_break_address.
5441 * infrun.c (wait_for_inferior): Don't set
5442 prev_{pc,sp,func_{start,name}} before calling wait ().
5443 Do set them after exiting loop.
5444 Move their declarations outside functions.
5445 (start_inferior): Initialize them.
5447 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5449 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5450 Restore old code which distinguishes between trap_expected and
5451 running_in_shell, just make the latter take any non-TRAP signal,
5454 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5456 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5457 xconfig/3b1 (CC,PINSN_CC): Define.
5459 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5463 * breakpoint.c (bpstat_stop_status),
5464 infrun.c (wait_for_inferior) [SHIFT_INST_REGS]: New code.
5466 * param.h, tm-88k.h: Define ADDR_BITS_*.
5467 infcmd.c (jump_command, read_pc), infrun.c (wait_for_inferior),
5468 printcmd.c (do_one_display): Use them.
5470 * utils.c: Split #ifdef USG into a USG_UTILS and a QUEUE_MISSING.
5471 xm-88k.h: Define USG_UTILS.
5473 Wed May 2 00:05:33 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5475 * printcmd.c (printf_command) [__INT_VARARGS_H]: New code.
5476 (printf_command): Add from_tty parameter.
5478 * valprint.c (value_print): Check VALUE_OPTIMIZED_OUT flag.
