1 Fri Sep 20 15:00:57 1991 Per Bothner (bothner at cygnus.com)
3 * mcheck.c: Add __ONEFILE kludge to allow compilation by non-ANSI
4 compilers (which may lack stddef.h).
6 Fri Sep 20 13:29:42 1991 John Gilmore (gnu at cygnus.com)
8 * dbxread.c (read_dbx_symtab, process_one_symbol): N_FN and
9 N_WARNING are the same except for the N_EXT bit, so just use their
10 values alone, rather than OR-ing them with N_EXT.
12 Fri Sep 20 12:27:55 1991 Stu Grossman (grossman at cygnus.com)
14 * mipsread.c (parse_lines): Deal with negative extended line
17 * c-exp.y, m2-exp.y: #define yyerrflag and yynerrs to avoid
18 global symbol conflicts.
20 Fri Sep 20 02:28:15 1991 John Gilmore (gnu at cygnus.com)
22 * .gdbinit: Move 'set complaints' to top, so it runs even in
23 case we aren't debugging GDB.
24 * language.c (_initialize_language): Fix type check and range
25 check documentation strings.
26 * utils.c (!HAVE_VPRINTF): Define vfprintf as a function, so
27 language.c can use it. (Though language.c should really not be
28 handling warnings/errors the way it does, FIXME.)
29 * symtab.c (lookup_primitive_type): const lint.
31 Bugfix from Peter Schauer:
32 * source.c (lines_to_list): Make signed, to avoid comparison
33 going unsigned and complaining that -3 is too high for 21 lines.
34 * stack.c (lines_to_list): Ditto.
36 Thu Sep 19 23:33:41 1991 John Gilmore (gnu at cygnus.com)
38 * Makefile.in (HFILES): Add minimon.h.
39 (VERSION): Roll version number to 4.0.95.
40 (gdb.tar.Z, make-proto-gdb.dir, setup-to-dist, gdb-XXX.tar.Z):
41 New rules for building distributions. Normal distribution
42 is built by doing `make -f Makefile.in gdb.tar.Z' in the directory
43 one level up from here; it calls make-proto-gdb.dir to build a
44 directory `proto-gdb' which is an image of the release. The old
45 `gdb.tar.Z' rule still works too.
46 * config.sub, configure: Roll in latest from ..
48 Thu Sep 19 17:41:24 1991 Roland H. Pesch (pesch at cygnus.com)
50 * doc/gdbint.texinfo: Reorder contents; reorganize new-host,
51 new-target, and new-config chapters; fix minor typos; come closer
52 to usual GNU markup conventions for @file @samp @code @var.
54 Thu Sep 19 17:04:12 1991 Per Bothner (bothner at cygnus.com)
56 Patches from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>:
57 * mipsread.c (parse_partial_symbols): Enter the name of all
58 structs/unions... into the psymtab so we can access them if the
59 symtab is not read in.
60 * mips-tdep.c: Remove some unneded (?) #includes.
61 * xconfig/dec3100: Add HAVE_STRSTR.
63 Thu Sep 19 15:14:23 1991 John Gilmore (gnu at cygnus.com)
65 * Makefile.in: Circumvent Sun Make bug on *-exp.tab.o.
66 * c-exp.y, m2-exp.y: Lint.
67 * m2-exp.y: Avoid using yytname[] which is a Bison-ism.

69 * mipsread.c (_initialize_mipsread): Avoid using
70 builtin_type_void at initialize time.
71 (mipscoff_symfile_read): use it now.
73 Wed Sep 18 15:55:51 1991 John Gilmore (gnu at cygnus.com)
75 Merge multiple-language support, and partial Modula-2 support,
76 from Andrew Beers <beers@cs.buffalo.edu>.
78 * i387-tdep.c: New file, consolidates most 80387 support,

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

173 Tue Sep 17 08:37:41 1991 John Gilmore (gnu at cygint.cygnus.com)
175 Add Andrew Beers' changes for Modula-2 support. His ChangeLog
176 entries are enclosed herein:
178 Mon Jun 3 17:05:45 EDT 1991
180 m2-exp.y Created. Tested outside of GDB for a few days. Proper
181 operators were added, C specific operators and tokens
182 removed. yylex() revamped to some extent. Still things
183 missing from the grammar, such as sets.
184 Tested for two weeks in GDB v3.5.
186 Tue Jun 11 17:23:48 EDT 1991
188 m2-exp.y Added boolean constants TRUE and FALSE to the grammar
189 so they are built-in. Sort of a hack.
191 Fri Jun 14 12:53:51 EDT 1991
193 m2-exp.y Added range checking for numeric constants. Any numeric
194 constant is assumed to be of builtin type INTEGER unless:
195 (1) it is octal or hexadecimal, in which case it is a
196 CARDINAL; (2) it is too big to fit into an INTEGER, in
197 which case it is a CARDINAL.
198 eval.c Added simple range checking for +, -, and * on integers.
199 Doesn't work very well for *, since 6 * 1,000,000,000 =
200 1,705,032,704, which fails the simple test of result >=
201 first_operand, no matter in what order the operands are.
203 Tue Jun 18 14:11:30 EDT 1991
205 Broke the parser into parts, one containing the C grammar and the other
206 containing code to be shared by all of the grammars.
208 The following files no longer exist:
213 The following files were added:
215 c-exp.y (The C grammar)
216 m2-exp.y (The Modula-2 grammar)
217 parser-code.c (Code that is shared by the above grammar)
221 Makefile.dist Changed to reflect the above dependencies. NOTE: It is
222 now necessary to use the Bison compiler compiler, since it
223 will generate function/variable prefixes other than yy.
225 Tue Jun 18 16:47:49 EDT 1991
227 symtab.[ch] Added the external variable working_lang, than holds the
228 value of the current working language.
229 Added the ennumerated type language_mode, with the values
230 language_auto and language_manual, the former meaning that
231 GDB sets working_lang as needed, and the latter meaning
232 that the value of working_lang is totally under user
234 symtab.[ch] Added the Modula-2 pervasive types INTEGER, CARDINAL,
235 REAL, BOOLEAN and CHAR. Also added the type codes
236 TYPE_CODE_BOOL and TYPE_CODE_CHAR.
237 utils.c Added set_language_command and show_language_command to
238 implement the GDB support commands "set language" and
240 expression.h A number of identifiers were added to the type exp_opcode
241 to facilitate Modula-2 builtin functions, integer
242 division, and array indexing.
244 Wed Jun 19 13:25:58 EDT 1991
246 language.h Added the macro STRICT_TYPE, which evaluates to non-zero
247 if the language specified by working_lang requires the use
248 of strict typing of expressions. Eventually, even this
249 will be able to be changed by the user.
250 Added the macro RANGE_CHECK, which evaluates to non-zero
251 if the language specified by working_lang requires the
252 checking of a value against the domain of its type.
253 Eventually, even this will be able to be changed by the
255 language.[ch] Predicates involving types (simple_type, ordered_type,
256 same_type, integral_type, numeric_type, character_type,
257 boolean_type, float_type) are added. These predicates are
258 based on the current value of working_lang, and are handy
261 Wed Jun 19 15:39:34 EDT 1991
263 eval.c Added the function type_array_rank which computes the rank
265 valarith.c Added the funtion value_bool, which when given a integer
266 value.h value (ie. struct value *) as an argument, it returns a
267 boolean value (ie. struct value *) true if that integer
268 is non-zero, and a boolean value false otherwise.
269 valprint.c Added cases for TYPE_CODE_BOOL, so Modula-2 BOOLEAN values
270 will print out properly.
272 Wed Jun 19 16:36:34 EDT 1991
274 valops.c Added the function value_capitalize, which returns it
275 value.h argument capitalized if its argument is a lowercase
276 letter, or the argument unchanged if its argument is not a
278 valarith.c Added the function range_check_p, which returns non-zero
279 value.h if its value argument is between the integral bounds upper
281 Added the function range_check_enum_p, which makes sure
282 that its value argument is a valid member of the domain of
284 Added the function range_check_range_p, which makes sure
285 its value argument lies between the upper and lower bounds
286 of its type argument, which must be a ranged type.
287 Added the function check_array_index, which range and type
288 checks an index of an array.
289 Added the function value_multi_subscript, which computes
290 array[idx1,idx2...idxN], given a value array and an array
291 of values representing indicies.
292 values.c Changed value_from_long to work with TYPE_CODE_CHAR and
293 unpack_long to work with TYPE_CODE_BOOL and
296 Wed Jun 19 18:04:08 EDT 1991
298 symtab.c Stored pervasive types in a structure and make
299 lookup_pervasive_type() a lookup function that was based
300 on working_lang. If lookup_pervasive_type() returned
301 non-zero, then that value was returned (a fix, since
302 before it simply wouldn't return the pervasive type.)
303 language.h Added the macro CAST_IS_CONVERSION, which evaluates to
304 non-zero if the language specified by working_lang means
305 "conversion" when it says "cast".
306 valops.c Added the function value_real_cast(), which performs a
307 value.h *cast*, not a *conversion*, which is what value_cast()
308 does when it can. In particular,
309 value_cast(<float_type>,4) = 4.0, while
310 value_real_cast(<float_type>,4) = some mess.
311 eval.c Modula-2 builtin functions implemented: ABS, CAP, CHR,
312 parser-code.c FLOAT, HIGH, MAX, MIN, ODD, ORD, TRUNC, and VAL.
313 expression.h Added macros MAX_OF_TYPE and MIN_OF_TYPE to work with MAX
314 and MIN on integral types. *NOTE*: These are currently
315 hardcoded to work only if there are 8 bits per storage
317 eval.c Made logical functions call value_bool to return a
318 properly typed boolean value, based on working_lang.
320 Thu Jun 20 11:55:27 EDT 1991
322 valprint.c Types now print out in a Modula-2 fashion. This works for
323 the cases when the type is printed out step-by-step, that
324 is, it doesn't work when the name of a structured type
325 (which includes the keyword "struct", etc.) is simply
327 FIXME: Perhaps this is bad. Parts of it seem to kludgey,
328 since type specifications in C and Modula-2 are very
329 different. The C printing of a type is very recursive,
330 whereas in Modula-2 it is generally very simple. C has
331 type prefixes and suffixes, which have no real analogue in
332 Modula-2. Maybe type_print() should call a language
333 specific type printer. This is also advantageous if we
334 compile GDB to exclude some of the languages. We'll just
335 leave those functions out.
337 Thu Jun 20 16:57:10 EDT 1991
339 dbxread.c When reading the complete symbol table in (via
340 psymtab_to_symtab()), the number and types of function
341 arguments are added to a function type. define_symbol()
342 calls add_param_to_type() to accomplish this.
343 Assumption: when we come across a function definition
344 (N_FUN symbol with an 'f' or 'F' in the name), its
345 arguments will appear before another function definition.
346 When a function is found, a pointer to its type is placed
347 in the global in_function_type. Changes that
348 add_param_to_type() makes are to this global.
349 valprint.c The type of a function now includes (for Modula-2) the
350 types of its parameters.
351 eval.c Type checking and a check for the proper number of
352 arguments is now done for function calls. Not sure of the
353 impact this has on C++ member function yet.
355 Thu Jun 20 19:58:48 EDT 1991
357 valprint.c Rewrote the type printer. Broke it into two language
358 specific parts, adding the functions type_print_m2() and
360 An unfortunate consequence is this: if you debugging a C
361 program in Modula-2 mode (why?), info types does not work
362 well with regular expressions, since the types are printed
363 out in Modula-2 terminology, but stored in C terminology.
364 language.[ch] Added the functions new_type_last(), type_keyword(), and
365 type_sep() to aid in the printing of typedefs.
366 symtab.c Made the printing of typedefs as language independent as
367 possible through calls to new_type_last(), type_keyword(),
370 Fri Jun 21 11:50:26 EDT 1991
372 dbxread.c Check all incoming ennumerated types. If it looks like
373 Modula-2's BOOLEAN type, then change the type_code of the
374 type to TYPE_CODE_BOOL so we can process it as a boolean
376 valprint.c Replaced some of the 0x%x with calls to sprintf and
377 hexformat() in val_print().
378 language.[ch] Added the function hex_to_string(), which converts its
379 integral argument to a hexadecimal number (format is
380 language based) and returns the result as a string.
382 Mon Jun 24 12:25:07 EDT 1991
384 valprint.c Some functions call type_print_1() directly, instead of
385 value.h using type_print(), so they can specify where (column) to
386 print things. Since type_print() takes care of language
387 dependence, that needs to be called first. Added a
388 parameter depth to type_print() (so it is now like
389 type_print_1). Changed type_print to type_print_at, and
390 made type_print a macro that passes a depth argument of
392 symmisc.c Changed all calls to type_print_1 to calls to
394 Makefile.dist Made it possible to build GDB for a specific set of
395 depend languages. Do this by passing a definition for the macro
396 LANGS to make. LANGS should be a string containing a
397 space-separated list of language names (ie. LANGS="c m2").
398 The default is to build all languages. Note that grammar
399 files must follow the naming convention of <lang>-exp.y.
400 gdb.lang This holds the current value of the LANGS macro. It is
401 examined every time make is called, and is updated if
403 eval.c Added #ifdef _LANG_<lang> to these files.
404 expread.c Still need to add them to dbxread.c and coffread.c.
412 Mon Jun 24 16:33:11 EDT 1991
414 language.[ch] Added the functions hexformat_pre() and
415 hex_to_string_pre(), which take a prefix argument to
416 include in the format string. Thus, hexformat_pre("08") will
417 return "0x08x" (if the working language is language_c).
418 Made hexformat() and hex_to_string() calls to the above
419 with "" as the prefix argument.
421 am29k-pinsn.c, arm-pinsn.c, breakpoint.c, convex-tdep.c, exec.c, core.c,
422 dbxread.c, i386-pinsn.c, i386-stub.c, i386-xdep.c, i960-pinsn.c,
423 infcmd.c, inflow.c, m68k-pinsn.c, m68k-stub.c, m88k-pinsn.c,
424 mips-pinsn.c, mips-tdep.c, ns32k-pinsn.c, printcmd.c, pyr-pinsn.c,
425 pyr-tdep.c, pyr-xdep.c, remote-vx.c, remote.c, solib.c, source.c,
426 stack.c, sun386-xdep.c, symfile.c, symm-xdep.c, symmisc.c, tahoe-pinsn.c,
427 valprint.c, vax-pinsn.c
429 Changed all occurences of 0x%[0-9]*l*x in printf format strings to
430 calls to hexformat() and hex_to_string(). Format strings without
431 the leading "0x" were ignored.
433 depend Updated to take the above into account.
436 Tue Jun 25 15:27:18 EDT 1991
438 symtab.h Added the types range_mode_t, range_check_t, type_mode_t,
439 and type_check_t to keep track of the current state of
440 range and type checking.
441 main.c Added the variables range_mode, range_check, type_mode,
442 and type_check to record the current state of range and
443 type checking. Added initialization code to main().
444 language.h Changed the macros STRICT_TYPE and RANGE_CHECK to examine
448 Tue Jun 25 17:57:08 EDT 1991
450 dbxread.c process_one_symbol() updates the variable (enum language)
451 source_lang based on the extension of the filename
452 contained in the N_SO sybmol that started this symtab.
453 When end_symtab() is called, the value of source_lang is
454 put into the language field.
455 stack.c select_frame() sets working_lang (and possibly type_check
456 and range_check) to the language field of the symtab
457 associated with the frame that is selected if working_mode
458 is language_auto. If working_mode is language_manual, a
459 warning is printed and working_lang is not set.
460 language.c Added the function set_type_range(), which sets the value of
461 type_check and range_check (if their modes call for
462 automatic setting) based on the current value of
463 working_lang. A non-zero argument will cause the current
464 settings to be output.
467 Wed Jun 26 14:51:40 EDT 1991
469 eval.c Added range checks on assignment.
470 m2-exp.y Added the grammar for sets to the language. Currently,
471 these do not do anything except print an error message.
473 Wed Jun 26 17:01:04 EDT 1991
475 m2-exp.y Added the ability for parse_number() to parse negative
476 numbers. A global flag is set upon encountering a unary
477 minus. This was done to make, for example, 1 parse as a
478 CARDINAL, and not as an integer, per Wirth's examples in
479 Programming in Modula-2 ed.4.
480 valprint.c Added support for "set radix 2" by then setting
481 output_format to 't'.
482 eval.c Implemented range checking on subrange types. Added calls
483 to range_check_range_p for BINOP_ASSIGN and BINOP_VAL.
484 Implemented MIN and MAX for ennumerated types. The
485 minimum value of an ennumerated type is defined by Wirth
486 as the first identifier, and the maximum as the last.
487 m2-exp.y Made octal numbers ending with "B" be characters and those
488 ending with "C" be numbers, per Wirth's book. (p. 34)
490 Thu Jun 27 14:11:52 EDT 1991
492 stack.c select_frame() now only sets working_lang, it does not
493 notify the user. If working_mode is language_manual, then
494 a warning is issued once.
495 main.c At the end of each call to execute_command(), working_lang
496 is checked against the local static (enum language)
497 current. If they differ and working_mode is
498 language_auto, the new settings of language, type and
499 range checking are printed out.
500 stack.c Modified frame_info() to include the language of the
501 current frame in the output of "info frame".
502 language.[ch] Added the function language_str() which returns the name
503 of the current language.
505 Fri Jun 28 15:33:14 EDT 1991
507 m2-exp.y Added the built-in procedures INC, INCL, DEC, and DECL to
508 the language. INCL and DECL currently cause an error,
509 since sets are not implemented yet. INC and DEC are
510 implemented as PREINCREMENT/PREDECREMENT with one
511 argument, and as ASSIGN_MODIFY with two arguments.
512 eval.c Added type checking to the above cases.
513 value.h Added not_lval_constant to the lval_type ennumerated type.
514 not_lval_constant means that the value is a constant
515 value; that is 3 or 'a' or TRUE, not as in a constant
516 identifier. This is used to help coerce numbers such as 3
517 to either signed or unsigned numbers.
518 valops.c Added the function value_coerce_constants() which coerces
519 constant integers as following: if one is a constant and
520 the other is not, the constant's type is set to the type
521 of the other argument. If both are constants and one is
522 signed, the other is converted to a signed constant.
524 Sat Jun 29 17:26:29 EDT 1991
526 valarith.c Added a better range checker. It now checks range
527 (successfully) on integral operations [+-] (signed and
528 unsigned) for any C sized type. Still does not work well
530 int_in_size() returns an integer that is coerced to fit into
531 specified number of bytes.
533 Mon Jul 1 13:04:14 EDT 1991
535 language.[ch] Added the function binop_result_type(), which returns the
536 builtin (struct type *) type that would be the result of a
537 binop on the two values V1 and V2.
539 Wed Jul 3 19:22:53 EDT 1991
541 source.c Extended source_info() to include the source language in
542 the output from "info source".
544 Fri Jul 5 13:48:52 EDT 1991
546 utils.c Moved the support functions for the GDB set/show commands
547 dealing with language into language.c.
548 language.c Added the function language_info(), which displays info
549 about the current working language, type and range check
550 settings. Called via the GDB command "info language".
551 Added an initialization routine _initialize_language(),
552 that sets defaults for the language, type and range
553 variables and sets up the new GDB commands.
554 main.c Language setup moved to language.c.
557 Mon Jul 8 10:10:22 EDT 1991
559 valarith.c Debugged the range checker for arithmetic. Still does not
560 work for multiplication very well.
562 Mon Jul 8 12:40:37 EDT 1991
564 language.[ch] Added the function value_true() which returns non-zero if
565 its argument represents a boolean true value.
566 breakpoint.c Changed breakpoint_cond_eval() to call value_true() to
567 check the truth of an expression.
569 Thu Jul 11 12:51:34 EDT 1991
571 language.[ch] Added the predicate structured_type(), which returns
572 non-zero if the argument is a structured type.
573 Added the predicate pointer_type(), which returns non-zero
574 if the argument is a pointer type.
575 eval.c Added the ability to do addition and substraction on
576 pointers and integers. This case simply bypasses the
579 Thu Jul 11 14:41:42 EDT 1991
582 Added the symbol N_DEFD (0x4a) which is a definition
583 module dependency that is used by the GNU Modula-2
584 compiler and the linker. It is not important to GDB,
585 except that [dbx|coff|mips]read.c should ignore these
588 Fri Jul 12 16:07:00 EDT 1991
590 valprint.c Changed the TYPE_LENGTH(type) >= 0 to TYPE_LENGTH(type) >
591 0 in val_print(). Also added statements to the else part
592 to coerce type (argument to val_print) to a pointer type
593 if it is an "array of unspecified length".
594 valops.c Added the function value_m2_string(), which returns a
595 (value) value which is a constant string, whose type is
596 (ARRAY [0..n] OF CHAR). The length field of the type
597 structure is set to zero, so it will be interpreted as an
598 "array of unspecified length".
599 stack.c Moved the language/frame mismatch check to
600 main.c:execute_command().
601 main.c The working language is recorded each time
602 execute_command() is executed. If working lang has
603 changed during its execution, then the new
604 language/type/range info is printed out for the user. If
605 the working language does not match the language of the
606 frame, a warning is issued.
608 Sat Jul 13 16:16:39 EDT 1991
610 eval.c Moved all the type-checking stuff for operators to
611 language.[ch] language.c. This is so we can keep language-specific
612 stuff (like for what type operators are defined) in
614 language.[ch] Added the function binop_type_check(), which checks to see
615 if its two (value) arguments are type-compatible with its
616 opcode argument. The opcode should represent an operation
617 involving an operator. Also added the macro function
618 unop_type_check, which calls binop_type_check with a
619 NULL second argument.
620 expprint.c Added Modula-2 operators to the op_print_tab, so info
621 expression.h break works correctly. Also added "op_string", which
622 returns the string corresponding to the (enum exp_opcode)
623 opcode that is its argument.
626 Sat Jul 13 18:26:18 EDT 1991
628 coffread.c Added code to record the type of function arguments with
629 each paricular function. Code is very similar to that
631 dbxread.c Moved add_param_to_type() to symtab.c
632 symtab.[ch] Added function add_param_to_type() from dbxread.c
634 *** NOTE: The above additions have not been tested.
636 Mon Jul 15 12:50:47 EDT 1991
638 langauge.[ch] Added the functions type_error and range_error, which work
639 like error() except if the type/range mode is set to
640 *_mode_warn, then they do not do a return_to_top_level(),
641 but merely print a warning.
642 Also changed [set|show]_[type|range]_command() to support
643 the new "warn" feature.
645 Thu Jul 18 17:50:54 EDT 1991
647 mipsread.c Added code to record the type of function arguments with
648 each particular function. Code is very similar to that
651 *** NOTE: The above additions have not been tested.
653 Fri Jul 19 11:19:10 EDT 1991
655 defs.h Added macros MAX_OF_SIZE, MIN_OF_SIZE, UMAX_OF_SIZE, and
656 UMIN_OF_SIZE, which when given a size of a numeric type,
657 return the maximum and minimum value it can hold. UMAX...
658 and UMIN... return the result for unsigned types.
659 symtab.h Added the macros MAX_OF_TYPE and MIN_OF_TYPE to operate on
660 struct types. They call above macros.
661 dbxread.c Renamed the MAX and MIN_OF_TYPE macros to ..._OF_CTYPE to
662 avoid a name conlict with the above.
663 c-exp.y Added range checking on numeric constants in
664 parse_number() for completeness.
665 valarith.c Made binop_user_defined_p() and unop_user_defined_p()
666 return 0 if working_lang is not language_c.
668 Thu Aug 8 14:17:22 EDT 1991
672 breakpoint.c Documentation strings of some commands changed to
673 eliminate the references to the C language where
676 Tue Aug 13 15:48:03 EDT 1991
678 m2-exp.y Added qualified identifiers to the grammar. The semantics
679 are slightly different from those of the GDB operator ::
681 m2-exp.y Added a rule to each grammar of the form: start ::= exp |
682 type_exp, where type_exp is any valid type expression.
684 eval.c Added the opcode OP_TYPE, and an error case in eval.c.
685 printcmd.c Modified ptype_command() so it actually parses the input
686 (necessary for type expressions with scope qualifiers).
687 Added the function ptype_eval() which expects an
688 expression composed of one OP_TYPE element.
689 *.[ch] Replaced all occurences of parse_c_expression with
691 *.[ch] Replaced all occurences of parse_c_1 with parse_exp_1
693 [End of ChangeLog entries from Andrew Beers for Modula-2 support.]
695 Mon Sep 16 17:19:46 1991 John Gilmore (gnu at cygnus.com)
697 Small fixes from Peter Schauer:
699 * infrun.c (child_attach): Lint.
700 * solib.c (find_solib): Handle shared libs version 2.
702 Small fixes from David Wood:
704 * xm-ultra3.h (SYS_SIGLIST_MISSING): Typo.
708 * remote-vx.c: Move <stdio.h> to top, for FILE. Fix from
709 John S <basrai%kanga.dnet@c3po.sm-alc.af.mil>.
711 * utils.c (wrap_here): Avoid wrap action of fputs_filtered if
712 chars_per_line is at maximum (user typed `set width 0'). Fix
713 from Andreas Schwab <schwab@ls5.informatik.uni-dortmund.de>.
715 Tue Sep 17 17:31:04 1991 Stu Grossman (grossman at cygnus.com)
717 * coredep.c: include ptrace.h where necessary.
718 * mipsread.c(parse_lines): fix unsigned char problem that was
719 messing up line numbers on SGI's and possibly other MIPS based
721 * infrun.c (child_create_inferior): use better test to check
722 return val from setpgrp().
723 * tm-irix3.h, xm-irix3.h, tconfig/irix3, xconfig/irix3: add these
724 for sgi/irix support.
726 Wed Sep 18 04:33:31 1991 Per Bothner (bothner at cygnus.com)
728 * mipsread.c (parse_symbol): Put non-static procedures
731 Fri Sep 13 00:14:52 1991 John Gilmore (gnu at cygnus.com)
733 Patch together `text_start' and `text_end' for 29K port.
735 * exec.c (exec_command): If NEED_TEXT_START_END, define the
736 variables and set them based on the exec file.
737 * am29k-tdep.c: declare text_start.
738 * valops.c (call_function_by_hand): declare text_end.
740 * inferior.h: Eliminate CANNOT_EXECUTE_STACK in favor of
741 defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
742 because machines that do this will also have to know to
743 set NEED_TEXT_START_END. Besides, it was a redundant way to
745 * tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
746 CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
749 Thu Sep 12 00:22:24 1991 John Gilmore (gnu at cygint.cygnus.com)
751 AMD 29000 changes from David Wood <wood@david.ultra.nyu.edu>:
753 * Makefile.in (CLIBS): Put XM_CLIBS and TM_CLIBS at end.
754 Pass MUNCH_DEFINE to munch whenever we run it.
755 * am29k-pinsn.c (print_insn): Handle NOP specially. Avoid %#x
756 format string; use 0x%x instead.
757 * am29k-tdep.c: Use DUMMY_SAVE_GREGS and RETURN_REGNUM.
758 * ultra-xdep.c, xm-ultra.h: New files for Ultracomputer host system.
759 * xm-rtbsd.h: New host support for RT/PC running BSD Unix.
760 * inflow.c: Handle `short' process group IDs.
761 * infptrace.c (fetch_register): Support CANNOT_FETCH_REGISTER,
762 and check for ptrace errors.
763 * coffread.c (SDB_REG_TO_REGNUM): Define if not already.
764 (coff_symfile_init): Initialize text_bfd_scnum.
765 (read_coff_symtab): Use it to find the text [and absolute?] sections.
766 * ../config.sub: Add vendor nyu and os "sym[1-9]*".
767 * configure.in: Add hosts rtpc-*-* and a29k-*-*.
768 Merge target arm case with other "easy" cases. Add target
769 cases a29k-*-none (rehack of am29k), a29k-*-kern (remote to
770 Ultracomputer kernel), and a29k-*-sym1 (ultracomputer OS's user
772 * minimon.h, remote-adapt.c, remote-mm.c: Add.
773 * munch: Cope with RT/PC putting fns in data segment.
774 Restore ability to override `nm' by specifying MUNCH_NM.
775 * xconfig/rtbsd, xconfig/ultra3: New host systems.
776 * tconfig/a29k: Rename from tconfig/am29k. Add remote-mm
777 and remote-adapt. Remove encapsulated coff #define's (the
778 support should go in BFD, and gdb shouldn't know or care).
779 * tconfig/a29k-kern: Same, but for remote kernel debugging.
780 * tconfig/ultra3: For debugging user processes on Ultra3/Sym1.
781 * tm-29k.h: Update BADMAG (though it should go away).
782 Allow the register definitions to be overridden in another
783 tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
784 RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
785 DUMMY_SAVE_GR96, for handling kernel calling conventions
786 that use GR64+ rather than GR96+.
787 * tm-ultra3.h: New file, for use on Ultra3 Unix as well as for
788 remote debugging of Ultra3 kernel. Includes tm-29k.h and
789 overrides various things.
791 * remote-mm.c (mm_attach, mm_wait): Handle attach like
792 child_attach does, making a clean stop in the newly attached
796 * coffread.c: Make coffread independent of any particular
797 variant of COFF. Avoid #include-ing any particular one except
798 internalcoff.h. BFD now passes key values for symbol reading
799 as part of its coff_data structure (LINESZ, SYMESZ, AUXESZ,
800 and the symbol masks and shifts); use them.
801 Remove obsolete end_of_text_addr.
803 * exec.c: Remove unused include files.
805 Wed Sep 11 19:38:44 1991 John Gilmore (gnu at cygint.cygnus.com)
807 * Makefile.in (documentation targets): Pass $(M4).
808 Bugfix from eggert@twinsun.com (Paul Eggert).
810 * stack.c (down_silently_command): Check for stack existence.
812 Tue Sep 10 23:08:29 1991 John Gilmore (gnu at cygint.cygnus.com)
814 * Makefile.in (VERSION): Update to 4.0.3.
816 Tue Sep 10 09:19:29 1991 John Gilmore (gnu at cygint.cygnus.com)
818 * core.c (core_file_command): Print frame at coredump with
819 its level number, by calling print_stack_frame.
820 * frame.h: Add selected_frame_level, print_stack_frame.
821 * frame.h, stack.c: Remove print_sel_frame, print_selected_frame.
822 * convex-tdep.c, convex-xdep.c, infcmd.c, inflow.c, infrun.c:
823 Change print_sel_frame and print_selected_frame callers to
826 * dbxread.c (read_ofile_symtab): Avoid empty else clause.
827 * symfile.c (free_named_symtabs): Ditto.
828 * main.c (main): wrap_here needs an arg.
829 * solib.c (find_solib): Avoid memory access if _DYNAMIC is zero.
830 (solib_add): Avoid noise.
831 (solib_create_inferior_hook): Lint.
832 (sharedlibrary_command): Move dont_repeat to here.
833 * utils.c (error): Call wrap_here to force buffered output.
835 Small patches from Peter Schauer:
837 * coffread.c (start_symtab): Free any existing line_vector before
839 (read_coff_symtab): Ditto for type_vector.
841 * source.c (lines_to_list): New variable, replacing function.
842 (all uses): Use as variable.
843 (_initialize_source): Add 'set listsize' and 'show listsize'.
844 * utils.c (lines_to_list): Remove function.
845 * stack.c (print_frame_info): Use as variable.
846 * defs.h (lines_to_list): Remove declaration.
848 Mon Sep 9 13:45:57 1991 John Gilmore (gnu at cygint.cygnus.com)
850 * breakpoint.c (insert_breakpoints): Restore warning about
851 the program might be running in another process, but only for
852 systems with this brain death (#ifdef ONE_PROCESS_WRITETEXT).
853 * xm-hp300bsd.h, xm-mips.h, xm-vax.h: Define it.
855 * utils.c (error): if error_pre_print is set, print the string
857 * main.c (main, print_gnu_advertisement, print_gdb_version):
858 Reformat legalese so it always prints, but acts as an "I'm here"
859 message while symbols are being read. If any errors occur,
860 print a few newlines to set off the message and start it at the
861 left margin. Remove mention of "help" command, and don't yak
862 about symbol reading.
863 (catch_errors): Error string is now printed first in case of
865 * command.c (undef_cmd_error, lookup_cmd): On undefined command,
866 suggest the "help" command.
868 * Makefile.in (VERSION): Set to 4.0.2.
870 Thu Sep 5 23:49:48 1991 John Gilmore (gnu at cygint.cygnus.com)
872 * .gdbinit: Remove useless "rr" command. Set complaints
873 to 1 for people debugging gdb.
875 * breakpoint.c, remote-vx.c: Reword strings printed by
876 catch_errors callers.
878 Wed Sep 4 11:07:50 1991 John Gilmore (gnu at cygint.cygnus.com)
880 * WHATS.NEW: "history write -> history save". Doc "write on/off".
881 (Fix from kenc@viewlogic.com.)
883 Fix some infrastructure to be able to cope with host and target
884 machines with different sized basic types (ints, ptrs, etc).
885 (Idea from pierre@la.tce.com (Pierre Willard).)
887 * values.c (value_from_longest): Rename from value_from_long.
888 Handle pointer types as well as integers, so that targets with
889 different pointer sizes from the host can be accomodated.
890 * breakpoint.c, convex-tdep.c, eval.c, expprint.c, printcmd.c,
891 valarith.c, valops.c, valprint.c, value.h, values.c: Rename
892 uses of value_from_long to value_from_longest.
893 * eval.c, findvar.c, printcmd.c, valarith.c, valops.c: Pass
894 the correct pointer type to value_from_long{est}.
896 * doc/gdb.texinfo ($_, $__): Describe types of these variables.
898 * remote-vx.c: Remove obsolete code for calling functions via
899 vxworks kludge interface (it referenced value_from_long).
901 * valops.c (value_string): Find malloc with lookup_misc_func, not
904 Tue Sep 3 18:37:46 1991 John Gilmore (gnu at cygint.cygnus.com)
906 Make writing to files work properly. (Fixes to BFD are also needed.)
908 * core.c (core_open): Open file ourselves, read or r/w, depending on
909 write_files. Use bfd_fdopenr.
910 * gdbcore.h (write_files): New variable.
911 * exec.c (write_files): Define variable, add set&show for it.
912 (exec_file_command): Use write_files to open for read or r/write.
914 Make shared library reading happen automatically. These changes
915 are mostly from Peter Schauer <pes@regent.e-technik.tu-muenchen.de>.
917 * inferior.h (stop_soon_quietly): Add to exported variables.
918 * infrun.c (child_create_inferior): call solib hook, if defined.
919 (child_attach): call solib hook, if defined.
920 * solib.c: Include inferior.h. Add from_tty to so_list as kludge.
921 (find_solib): Use lookup_misc_func rather than hand-rolled.
922 (symbol_add_stub): New stub for catch_errors.
923 (solib_add): Avoid output if !from_tty. Catch errors rather
924 than just calling symbol_file_add and bombing.
925 (solib_create_inferior_hook): Interface with the target process
926 to let it read and alloc shared libs, then figure out what it did.
928 * core.c (validate_files): Fix typo, soften warning.
929 (Fix from Hiroto Kagotani <kagotani@cs.titech.ac.jp>.)
931 * utils.c (fputs_demangled): Avoid duplicate printing if
932 demangling is off. (Fix from J.T. Conklin <jtc@cayenne.com>.)
934 * infrun.c (proceed): Cast -1 to (CORE_ADDR) before comparing.
935 (Fix from pierre@la.tce.com (Pierre Willard).)
937 * main.c (catch_errors): Change argument to a char * from an int,
938 since a char * can point to a struct full of glop, but an int
939 is not guaranteed to be able to hold a pointer.
940 * breakpoint.c (breakpoint_cond_eval, bpstat_stop_status,
941 breakpoint_re_set_one, breakpoint_re_set): Adapt.
942 * core.c (core_open, solib_add_stub): Adapt.
943 * remote-vx.c (symbol_stub, add_symbol_stub, callers): Adapt.
945 Wed Aug 28 18:18:05 1991 John Gilmore (gnu at cygint.cygnus.com)
947 * Makefile.in: Update VERSION to 4.0.1. Evade GNU Make bug
948 by adding .NOEXPORT target.
950 Fri Aug 23 17:14:25 1991 John Gilmore (gnu at cygint.cygnus.com)
954 * Makefile.in (VERSION): Roll to 4.0.
955 (gdb.tar.Z): Make refcard.ps as well, for shipment.
957 Fri Aug 23 14:07:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
959 * doc/gdb.texinfo: minor rewordings, crossref to ptype from print,
962 * doc/Makefile, Makefile.in: generate "gdb-all.texi" rather than
965 * doc/rdl-apps.texi: renamed from rdl-apps.texinfo
967 * Makefile.in, doc/Makefile, doc/.Sanitize, doc/gdb.texinfo:
968 reflect above name change
970 * WHATS.NEW: correct pointer to refcard.
972 * doc/gdb.texinfo: update New Features, Installing
974 * doc/gdbint.texinfo: add short description of configure +template
976 Fri Aug 23 11:46:08 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
978 * doc/gdb.texinfo: update, fix bugs in "Installing" appendix
980 Fri Aug 23 01:02:00 1991 John Gilmore (gnu at cygint.cygnus.com)
982 * Makefile.in: Add config.sub, make doc/rdl-apps.texinfo for
983 tar file, add dependencies for referenced doc files.
985 Thu Aug 22 22:17:06 1991 Stu Grossman (grossman at cygint.cygnus.com)
987 * coffread.c, symfile.c, stack.c: saberized.
989 Thu Aug 22 16:20:27 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
991 * doc/refcard.tex: permuted Essential Commands sec
993 * doc/gdb.texinfo: new C++ chapter; revised installation appendix;
995 set/show symbol-reloading
996 default set complaints 0
998 RET-repeat disabled after prompted long displays
999 processID (attach) interpretation of 2nd GDB cmdline arg
1001 Thu Aug 22 14:05:47 1991 Stu Grossman (grossman at cygint.cygnus.com)
1003 * expread.y, coffread.c, dbxread.c, target.c, mem-break.c,
1004 cplus-dem.c, values.c, valprint.c, symfile.c, remote.c,
1005 breakpoint.c, main.c: lint.
1007 Thu Aug 22 02:02:26 1991 John Gilmore (gnu at cygint.cygnus.com)
1009 Install new configuration scheme for GDB and friends.
1011 * config.sub: Translate ordinary names to three-part names.
1012 * configure: Use three-part names internally.
1013 * configure.in: Translate three-part names to filenames.
1015 * README, WHATS.NEW: Update for gdb-4.0.
1016 * Makefile.in: Roll VERSION to 3.99.
1018 Wed Aug 21 18:21:09 1991 John Gilmore (gnu at cygint.cygnus.com)
1020 * infptrace.c (KERNEL_U_ADDR_BSD): Include a.out.gnu.h.
1021 * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
1022 tm-m68k.h, remote-nindy.c: Change ext_format_XXX structs
1023 to single structures rather than arrays; when passing
1024 their address, use &. This avoids trouble with bdead compilers.
1025 * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
1026 instead. This avoids portability headaches.
1027 * mips-tdep.c (mips_do_registers_info): Only print FP regs if
1029 * source.c (open_source_file): Avoid ANSI const bdeath by
1030 skipping declaration and then casting result value.
1031 * tm-hp300bsd.h: Clarify comment.
1032 * utils.c (strstr): Result is const char *; ANSI bdeath.
1033 * xm-hp300bsd.h: Define HOST_BYTE_ORDER. Redefine INT_MIN,
1034 since system include file defines it differently from "defs.h",
1035 though the two are equivalent for our purposes.
1036 * tconfig/hp300bsd: Add m68k-tdep.o.
1038 Tue Aug 20 16:01:11 1991 John Gilmore (gnu at cygint.cygnus.com)
1040 * tconfig/sun*4: Remove warnings about system assembler.
1042 Mon Aug 19 13:44:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1044 * mcheck.c: Avoid warning about undeclared abort fn.
1045 * tm-sparc.h (PC_ADJUST): Avoid calling error() from this;
1046 it causes recursive calls to error() when used in cleanups.
1047 To do so requires that we make it a function, so we do.
1048 * sparc-tdep.c (sparc_pc_adjust): New implem of PC_ADJUST.
1049 * utils.c (do_cleanups): Remove the current cleanup from the
1050 chain *before* calling it, in case error() is called from it.
1051 The result won't be pretty, but won't be an infinite loop either.
1053 Mon Aug 19 00:41:04 1991 Michael Tiemann (tiemann at cygint.cygnus.com)
1055 * dbxread.c (read_struct_type): Grok anon structs for C++.
1056 (vb_name, vptr_name): Null terminate these strings.
1058 Fri Aug 16 08:31:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1060 Minor bug fixes from BSD Net2 gdb:
1062 * blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE
1063 returns 0, there is no previous frame.
1064 * breakpoint.c (commands_command): If !from_tty, don't call
1065 input_from_terminal_p().
1066 * dbxread.c (record_misc_function): Speed up slightly.
1067 (compare_psymbols): Ditto.
1068 * infcmd.c (do_registers_info): Take a second argument to
1069 determine whether to print float registers. "info registers"
1070 does not do so anymore. "info all-registers" does, now.
1071 * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second
1073 * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg.
1074 * inflow.c (initialize_inflow): Set tflags_ours correctly.
1078 * breakpoint.c (bpstat_do_actions): Use a cleanup to restore
1079 executing_breakpoint_commands if we are interrupted by error.
1080 * coffread.c (init_lineno): Avoid problem with zero-sized linetab
1081 versus malloc/free. From: john@labtam.labtam.oz.au (John Carey).
1082 * core.c (solib_add_stub, core_open): Call SOLIB_ADD inside a
1083 catch_errors() so we can setup the frame regardless of whether
1084 the shared libs work.
1085 * ieee-float.c (double_to_ieee_extended): Get exponent from
1086 right place in little-endian systems. From John Carey.
1088 Thu Aug 15 18:43:57 1991 John Gilmore (gnu at cygint.cygnus.com)
1090 * main.c: Remove unused terminating_signals and catch_termination().
1091 (long_options): Terminate with a zero element.
1092 [Bugfix from Atsuo Kawaguchi <atsuo@hark86.harl.hitachi.co.jp>.]
1093 (gdb_readline): Make call-compatible with readline.
1094 (init_signals): Improve comments re vfork vs. signal.
1096 * utils.c (prompt_for_continue): Use new gdb_readline().
1097 If we prompt for continuation, we don't let CR repeat the previous
1098 command, once we get back to a prompt. It's too easy to keep
1099 hitting CR, expecting "--more--" prompts, and have some long
1100 command start repeating on you.
1102 Tue Aug 13 16:17:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1104 * blockframe.c (frameless_look_for_prologue): Speed up by
1105 calling SKIP_PROLOGUE_FRAMELESS_P if it's defined.
1106 * tm-sparc.h (SKIP_PROLOGUE, SKIP_PROLOGUE_FRAMELESS_P):
1107 Define two variants, one faster.
1108 * sparc-tdep.c (sparc_frame_chain): Use target_read_memory
1109 and return zero, rather than giving an error.
1110 (setup_arbitrary_frame): Initialize the PC in the new frame.
1111 (skip_prologue): Add a second arg saying whether we're just
1112 checking for a frameless function or not.
1114 * core.c (core_open, core_close, core_xfer_memory): Move
1115 section table pointers and bfd* into the target_ops.
1116 (core_open): Allow errors in shared lib reading, etc.
1117 (core_files_info): Describe shared library sections.
1119 * exec.c (exec_open, exec_close, exec_xfer_memory, xfer_memory,
1120 exec_files_info, set_section_command): Move section table
1121 pointers and bfd* into the target_ops.
1122 (add_to_section_table): Add BFD to section table.
1124 * target.c (target_xfer_memory, target_info): Pass target to
1125 xfer_memory and target_info functions.
1128 * gdbcore.h: Move struct section_table.
1129 * target.h: New home of struct section_table.
1131 * solib.c (solib_add): New argument is the target_ops whose
1132 section list is to be added to, if any. Reallocate the
1133 sections in that target to add any that come from shared libs.
1134 (throughout) so_sections renamed to sections.
1135 (solib_xfer_memory): Deleted.
1136 * tm-sunos.h (SOLIB_ADD): Add target argument.
1137 (SOLIB_XFER_MEMORY): Delete.
1139 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
1140 remote-vx.c, remote.c, target.c, target.h: Remove add_syms vector
1141 from target_ops. It's the same on all targets. Add two section
1142 pointers to target_ops.
1144 * stack.c (find_relative_frame): Dump ancient algorithm for
1145 "down", just use handy "next" pointers.
1146 (frame_command): Don't error if there is no stack; let user
1149 * inflow.c (new_tty_prefork, new_tty): New prefork routine
1150 modifies static state in the parent process; new_tty itself
1151 runs in the child and modifies the child's file descriptors
1152 to match the saved static state.
1153 * infrun.c (child_create_inferior): Call new_tty_prefork,
1156 * infptrace.c (child_xfer_memory): Add ignored target arg.
1157 * remote-eb.c (eb_xfer_inferior_memory): ''
1158 * remote-nindy.c (nindy_xfer_inferior_memory): ''
1159 * remote-vx.c (vx_xfer_memory): ''
1160 * remote.c (remote_xfer_memory): ''. Rename from
1161 remote_xfer_inferior_memory.
1163 * main.c (main): Only try to attach "corefile" argument if
1164 it starts with a digit.
1166 * symfile.c (symbol_reloading): New "set/show" variable.
1167 (symbol_file_add): Shorten message about symbol reading.
1168 (add_symbol_file_command): Merge with add_syms_addr_command,
1169 since this should work on all targets now.
1170 (stop_whining): Default to zero, to shut up complaints
1171 about bad symbol tables on many systems.
1172 (free_named_symtabs): Just exit unless symbol_reloading.
1174 * xm-sun3os4.h, xm-sun4os4.h: Define BROKEN_LARGE_ALLOCA,
1175 and add comment explaining shared library screw.
1177 * source.c: #if defined => #ifdef.
1179 Thu Aug 8 12:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
1181 * doc/gdbint.texinfo: Improve doc on porting to new OS's.
1183 Tue Aug 6 17:16:15 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1185 * doc/rdl-apps.texinfo: provide default readline-appendix finder
1186 (doc/Makefile knows how to make one for local config)
1188 * Makefile.in: use doc/Makefile for doc targets
1190 * doc/Makefile: GDB documentation now has its own Makefile
1191 doc/refcard.tex: renamed from "gdbrc.tex"
1192 doc/.Sanitize: add Makefile; recognize renamed refcard.tex
1193 doc/gdbint.texinfo: add markup in "Cleanups" chapter
1196 Fri Aug 2 00:13:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1198 * values.c (baseclass_addr): When reading target memory, use the
1199 length of the basetype, not the upper type. We've only malloc'd
1200 enough space for the basetype, leading to errors in free().
1202 * expprint.c (print_subexp): Print UNOP_MEMVAL of an OP_LONG that
1203 ends up as a function specially, since we know the actual type of
1204 the pointed-to address. This (somewhat) fixes display of
1205 expressions that include misc_function_vector names. Try `cond 1
1206 !strcmp("a","b")' then `i b'.
1208 * infrun.c: Move DO_DEFERRED_STORES from proceed() to resume().
1209 The child can be proceeded from inside wait_for_inferior in
1210 evaluating breakpoint conditions, and DO_DEFERRED_STORES was
1211 getting skipped in that case.
1213 * expprint.c (print_subexp): Use filtered output, since the
1214 subroutines we call use it, otherwise the output is horribly
1215 mangled, since output of wrappable stuff comes out late.
1217 * Makefile.in: Bump VERSION to 3.98.1
1219 * infrun.c (child_create_process): Use execlp to find the
1220 shell to exec our target program. This requires some fiddling
1221 with `environ' since there is no execlpe().
1223 Thu Aug 1 15:35:17 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1225 * Makefile.in, doc/gdbrc.tex, doc/rc-* (new files):
1226 Minor rearrangement of refcard permits two new make targets--
1227 gdbrc.dvi DVI output for refcard, using CM fonts
1228 gdbrc.ps PostScript refcard, using PS fonts
1230 Wed Jul 31 16:46:21 1991 John Gilmore (gnu at cygint.cygnus.com)
1234 * TODO, Projects, WHATS.NEW, README: Update for gdb-3.98.
1235 * Makefile.in (gdb-all.texinfo): Avoid touching file if M4 dies.
1237 Wed Jul 31 16:35:58 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1239 * doc/gdb.texinfo: last changes for release.
1240 Minor typo and formatting fixes; incorporated most fixes remaining from
1241 filed mail commenting on earlier drafts.
1243 Added warnings: pipes don't work in run command;
1244 conditions are converse of assertions;
1245 step over fn without debug info goes to next fn;
1246 vars may have "wrong" values near fn entrance, exit
1248 Added example from Kingston on printing repeated nonadjacent values
1250 Added explicit mention that in Emacs gdb mode C-c and C-z are like
1251 shell mode for signals
1253 Renamed "Stepping and Continuing" to "Continuing and Stepping" so it
1254 doesn't sound so much like its parent "Stopping and Continuing"; also
1255 moved entries on continue to top of section, so they don't get lost.
1257 Improved installation directions in appendix, added manual formatting
1260 Tue Jul 30 17:26:39 1991 John Gilmore (gnu at cygint.cygnus.com)
1262 * configure.in: Remove xm.h and tm.h even if we aren't linking
1263 new ones, so "./configure sun4; ./configure none" does the right
1264 thing. Assume that alldeps.mak and depend are already built in
1265 srcdir, and avoid running "make" (particularly "make depend",
1266 which involves "gcc") from inside configure. Build Makefile
1267 directly rather than building Makefile.conf first.
1268 * configure: Regenerate with above changes.
1269 * Makefile.in: Use $(BISON) to find bison. Roll VERSION
1270 to 3.98. Revise gdb.tar.Z procedure to produce a file
1271 called gdb-$(VERSION).tar.Z but which unpacks into a
1272 directory called "gdb". Move non-source files out of
1273 $(SFILES_SUBDIR). Pretty up alldeps.mak with comments.
1274 (depend): Don't try to do "gcc expread.y".
1275 (expread.o): Update dependencies by hand.
1277 Mon Jul 29 15:21:09 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1280 Fixed a variety of small typos that prevented info from formatting
1281 cleanly; altered too-long heading for GPL Appendix, as discussed
1282 w/RMS; Changed date on cover to July 91.
1284 Fri Jul 26 13:20:02 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1287 (1) Applied some fixes due to comments from Larry Breed (easier ones
1288 through chapsec 5.2)
1289 (2) Eliminated use of @footnote---had my doubts about it anyways, and
1290 it's broken in latest texinfo
1291 (3) Introduced *some* use of [] for optional arguments, where
1292 explanation is not simpler by listing cmd w arg and cmd w/out arg
1293 separately. Still not using @deffn.
1294 (4) Dropped in GPL-2. NOTE: one of GPL-2 or texinfo is broken; a
1295 couple of headings are too long. Need patches to texinfo or revision
1298 * Partial update to README (which still needs work for this
1299 release!): (1) use of configure corrected for new script,
1300 (2) "make gdb.dvi" and "make gdb.info" mentioned.
1302 Wed Jul 24 06:44:02 1991 John Gilmore (gnu at cygint.cygnus.com)
1304 * symtab.c (lookup_symbol): Don't complain right off about
1305 no debug symbols; use the misc function vector first.
1306 (list_symbols): Use misc function vector to find symbols
1307 that don't have debug info, and print them.
1308 (find_pc_symtab): Temporarily avoid fatal() when psymtab
1309 PC range doesn't match symtab PC range, as it does on the
1310 MIPS because our symtab reading isn't perfect.
1312 * dbxread.c (dbx_symfile_read): Make warning about
1313 "no debug symbols" slightly nicer.
1315 * source.c (select_source_symtab): If "main" symbol exists,
1316 but decode_line_spec can't find line info, don't just return
1317 a zero; try other source symtabs or give an error.
1319 * mipsread.c (parse_partial_symbols): Sort the psymtabs by
1320 their low addresses first, then rip through fixing high addrs.
1322 * ns32k-opcode.h (sfsr): Bugfix from Rune Nerg}rd,
1323 <runene@ifi.uio.no>.
1324 (NS32K_SVC_IMMED_OPERANDS): Reverse the #ifndef.
1326 Tue Jul 23 18:52:43 1991 Roland H. Pesch (pesch at cygint.cygnus.com)
1328 * Minor, mostly mechanical, cleanup of doc subdir for clean
1329 makeinfo'ing and TeXing; also ensured gdb-all.texinfo (post-m4)
1330 and gdb.info (post- texinfo2 makeinfo) generated for distribution.
1332 Sun Jul 21 03:54:52 1991 John Gilmore (gnu at cygint.cygnus.com)
1334 Mostly MIPS and general symbol-reading fixups.
1336 * doc/gdbint.texinfo: Add documentation on symbol-reading
1339 * mipsread.c: Remove kludges around #include "ecoff.h".
1340 Remove redefinitions of a_magic, etc, no longer used.
1341 (parse_symbol, ): Convert "Internal:" printfs to complain()ts.
1342 Fix global overview comments to match symfile.c protocol.
1343 (mipscoff_new_init): Eliminate cur_hdr if we have one.
1344 (mipscoff_symfile_read): Eliminate unused code. Avoid
1345 sorting all the symtabs, when all we have read here is psymtabs.
1346 The symtabs are sorted as they are created anyway. Tell
1347 condense_misc_bunches whether we're mainline.
1348 (psymtab_to_symtab_1): Pass filename when recursing, to make
1349 stack trace more informative.
1350 (parse_partial_symbols): Assume cur_hdr as argument.
1351 (read_mips_symtab): Don't clobber cur_hdr, so it can be freed.
1352 Pass cur_hdr implicitly to parse_partial_symbols. Avoid checking
1353 the TYPE_NAME of char *, since that's done in symfile.c.
1354 (free_numargs, parse_symbol, add_symbol, add_block,
1355 shrink_linetable): Declare these fns void.
1356 (upgrade_type): Convert tree of if's to switch. Clean up
1357 bogus "off == 0" handling with a complaint. Avoid setting
1358 field bitpos and bitsize of array with lower and upper bounds.
1359 Check specified bitsize of elements against their actual type's
1360 bitsize, and complain if different. Complain about unknown
1362 (parse_fdr): Don't assume sizeof(char *) == sizeof (struct *).
1363 (psymtab_to_symtab_1): Print names of subsidiary files that
1364 are being read in. FIXME, we read far too many files. This code
1365 is not the problem, the problem is in parse_fdr where the psymtabs
1367 (cross_ref): Result should indicate that we used one aux entry
1368 normally, or two if we encountered a "next" entry. This used
1369 to leave the caller pointing at the wrong aux entry.
1370 (add_symbol): If overflowed cur_block, reallocate it larger,
1371 chase all pointers to it, and complain(), rather than clobber memory.
1372 (shrink_block): Use xrealloc rather than xmalloc-and-copy.
1373 (new_field): Only allocate one field initially, not two.
1374 Pull ++ out of macro argument. Simplify.
1375 (_initialize_mipsread): Avoid initialization of importd
1376 global_psymbols and static_psymbols.
1378 * symfile.c (psymtab_to_symtab): Depend on XXX_psymtab_to_symtab
1379 to properly set pst->symtab; avoid searching for it.
1380 (symfile_fns): Improve comments, add a FIXME.
1381 * dbxread.c: Update comments to reflect symfile protocol.
1382 (read_ofile_symtab, end_symtab): Return the symtab.
1383 (psymtab_to_symtab_1): Set pst->symtab.
1385 * coffread.c (coff_symfile_read): tell condense_misc_bunches
1386 whether we're mainline.
1388 * symfile.h (sym_fns): Remove unused sym_discard member.
1389 * coffread.c, mipsread.c, dbxread.c: Remove XXX_symfile_discard.
1391 * mtrace.c (mtrace): Take effect if mallwatch is set, even if
1392 the environment variable is not.
1393 * infcmd.c (finish_command): Use filtered printfs.
1394 * cplus-dem.c: Add struct tags to a few unnamed structs.
1395 * valops.c (value_coerce_array): Improve comments.
1396 * valprint.c (type_print_varspec_suffix): Print array size only
1397 if greater than zero.
1398 * m88k-tdep.c: Shift some lines left by one space, that had
1399 apparently been trashed at some point.
1400 * TODO: More things to do, a few got done.
1402 Thu Jul 18 22:46:05 1991 John Gilmore (gnu at cygint.cygnus.com)
1404 * symtab.h (LOC_EXTERNAL): Eliminate in favor of LOC_STATIC.
1405 (ldsymoff, ldsymlen, globals_offset, statics_offset): Improve
1407 * dbxread.c (read_dbx_symtab): LOC_EXTERNAL -> LOC_STATIC.
1408 * expread.y, findvar.c, symmisc.c: Ditto.
1409 * printcmd.c (address_info): Update printed forms of LOC_
1410 symbols. Elim LOC_EXTERNAL.
1411 (print_frame_args): Keep track of param stack offsets before
1412 re-looking up to find the local register param is kept in.
1414 * mipsread.c: Use <symconst.h> and <sym.h> rather than <syms.h>.
1415 Further integration of mipsread into gdb. Eliminate unused
1416 routines, duplicate declarations. Handle static symbols in
1417 psymtabs as well as external symbols. When reading symtabs,
1418 insert symbols into the correct block (global, static, or a local
1420 (read_mips_symtab, parse_partial_symbols): Don't pass useless
1422 (mipscoff_symfile_read): Don't call select_source_symtab.
1423 (parse_symbol): Use SYMBOL_VALUE_ADDRESS where appropriate,
1424 rather than SYMBOL_VALUE.
1425 (parse_external): Comment clobbering of top_stack.
1426 (parse_partial_symbols): Update comments. Allocate and parse
1427 static symbols as well as external symbols. FIXME, enum values
1428 are not handled in this pass, but should be. Inline new_psymbol.
1429 Use SYMBOL_VALUE_ADDRESS.
1430 (psymtab_to_symtab_1): Read symbols into global static block
1431 by default (until enter some function's local block context).
1432 (sort_blocks): Clean up STATIC_BLOCK as well as GLOBAL_BLOCK.
1433 (destroy_all_symtabs, new_psymbol): Eliminate, unused.
1435 * source.c (select_source_symtab): Select a source symtab
1436 from either the symtabs or, failing that, the psymtabs.
1437 (list_command): Update error message.
1438 (forward_search_command, reverse_search_command): Use getc, not
1439 fgetc, for speed. FIXME, add comment about buffers that die if
1440 overrun by long line.
1442 * values.c (unpack_field_as_long, modify_field): Avoid shifting
1443 by an entire word, which is not portable, if we have a 32-bit
1444 field. (Code in dbxread.c already turns such bitfields, if
1445 aligned, into ordinary ints, but fixing this will help for other
1446 symbol formats and for future changes.)
1447 * core.c (core_open): Handle ANSI const brain death.
1448 * utils.c (vprintf): Fix varargs typo.
1450 Sun Jul 14 00:42:53 1991 John Gilmore (gnu at cygint.cygnus.com)
1452 * findvar.c (find_var_value): Handle &function better.
1453 * TODO: Document work needed on &fn and &array.
1454 * printcmd.c (print_address_symbolic): New arg is the prefix
1455 to print if a name is printed.
1456 (print_address_demangle): Honor "set print address" now.
1457 Use new arg above to improve spacing of output.
1458 * valprint.c (val_print): When printing function pointers,
1459 print symbolic form too.
1460 * breakpoint.c (breakpoint_1): Use new print_address_symbolic.
1462 Mon Jul 8 19:02:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1464 * core.c (memory_error): Reword error msg to mislead less.
1466 * mips-pinsn.c (print_insn_arg 'd'): Print $ with reg name.
1468 * mipsread.c (read_mips_symtab, read_the_mips_symtab,
1469 parse_partial_symbols): Use newer BFD internals (external_filehdr
1470 and external_aouthdr), byte-swap the fields that we care about
1471 before using them, and make the file header data local to
1472 read_the_mips_symtab rather than global.
1474 Sat Jul 6 01:34:15 1991 John Gilmore (gnu at cygint.cygnus.com)
1476 * ns32k-opcode.h (movmw, movmd): Fix opcodes. Bug fix
1477 from Rune Nerg}rd <runene@ifi.uio.no> on 5 Jul 1991.
1479 * main.c (command_line_input): Flush stdout and stderr
1480 before every call to readline. This reportedly fixes a bug
1481 that comes up in Sys V running emacs-gdb and/or xxgdb,
1482 when stdin/out are pipes or sockets.
1484 Thu Jul 4 14:47:06 1991 John Gilmore (gnu at cygint.cygnus.com)
1486 * configure.in, Makefile.in: Avoid rebuilding "depend" as much.
1487 Avoid declaring Makefile dependencies, because GNU Make stupidly
1488 tries to update it if we do.
1490 * coffread.c: Revise for minor changes to bfd internal coff
1493 * configure: If -template= is given a relative path, make it
1494 absolute before recurring in subdirectories.
1496 * configure, configure.in, Makefile.in: Install "configure" script
1497 as replacement for config.gdb.
1498 * config.gdb, Makefile.dist, Makefile.sdir: Remove
1499 * README: Update for configure, mostly. FIXME.
1501 * Add dec3100 as equivalent to littlemips. Indicate in all host &
1502 target config files that they are for the host. When the lines
1503 get copied into the Makefile, this makes it more obvious what's
1506 Mon Jun 24 23:49:07 1991 John Gilmore (gnu at cygint.cygnus.com)
1508 * sparc-opcode.h (trap opcodes): Avoid leading spaces or
1509 tabs, which end up in the disassembler output inadvertently.
1511 Wed May 29 23:01:03 1991 John Gilmore (gnu at cygint.cygnus.com)
1513 Make it compile cleanly in an ANSI GCC2 environment.
1515 * blockframe.c: <stdio.h>
1516 * cplus-dem.c: free takes a void *, ifdef __STDC__
1517 * dbxread.c (read_huge_number): avoid gcc2 bug hoisting calc of
1519 * defs.h (alloca): Avoid doing anything if alloca already def'd.
1520 * stddef.h, stdlib.h: Remove these files.
1521 * symtab.c: Avoid declaring qsort, close.
1522 * symfile.c: Avoid declaring close.
1523 * utils.c (vprintf): Declare "ap" arg as proper va_alist.
1524 * sparc-tdep.c: Avoid including lots of Sun-host-specific files.
1526 Assorted other changes.
1527 * dbxread.c: include "libaout.h", not "liba.out.h".
1528 * printcmd.c (print_frame_args): Set recurse properly for
1529 indentation of struct and array parameters.
1530 * valops.c (value_cast): Allow cast to void.
1531 * infrun.c (resume): If NO_SINGLE_STEP, call machine dependent
1532 single_step() in a target-independent fashion.
1533 * sparc-tdep.c (single_step): Don't call ptrace ourselves, just
1534 set up to be ready to continue. This makes us target independent.
1535 * infptrace.c (child_resume): Remove call to single_step; now
1536 can single step a SPARC target of any kind.
1538 Wed May 22 18:18:24 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1540 * Makefile.dist, doc/gdb.texinfo, doc/*-m4.texinfo: split up GDB
1541 docn into separate sections---basically chapters, plus two loose
1542 pieces that can be configured to go in different places. This
1543 allows GNU m4 to preprocess the manual without coredumping.
1545 * Makefile.dist: tell TeX where to find texinfo.
1547 Mon May 20 12:15:04 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1549 * Makefile.dist, doc/gdb.texinfo: respectively create, and use,
1550 the new target "rdl-apps.texinfo" which captures the Makefile
1551 variable that records where to find the Readline libraries.
1553 Sun May 19 05:36:59 1991 John Gilmore (gnu at cygint.cygnus.com)
1555 * tahoe-pinsn.c: #include "tahoe-opcode.h", not "opcode.h".

1557 * defs.h (const, volatile): Only define if not already defined.
1558 * Makefile.dist (gdb.tar.Z): Create doc subdir w/out CVS/RCS crud.
1560 * README: Update for release 3.95.
1561 * config.gdb: Don't create readline dir in subdir builds.
1562 * main.c: Include with "..." form for non-system include files,
1563 so "gcc -MM" for "make depend" works.
1564 Include readline files with "...h" rather than <readline/...h>.
1565 * mipsread.c: Include "ecoff.h" rather than "intel-coff.h".
1567 * coffread.c: Undo minor damage done by Rich Pixley. Use
1568 different internal and external representations of COFF
1569 data structures. Use new BFD routines for swapping them in and
1571 * symfile.c (free_named_symtabs): Avoid freeing file names that
1572 are null or empty. Old i960 tools seem to produce files that
1573 claim to have empty names, causing each successive file read
1574 to blow away the previous one.
1575 * sparc-xdep.c (deferred_stores): Repair minor damage by Rich.
1576 Move deferred_stores to top of file, but don't separate its
1577 #define's from its variable. Add commentary.
1578 * Makefile.dist: Fix Rich damage; undo "configure" changes in
1579 favor of keeping the (working) config.gdb. Move readline
1582 Fri May 17 12:49:56 1991 Per Bothner (via gnu at cygint.cygnus.com)
1584 * dbxread.c (read_struct_type): Try to handle g++ version 1 MI
1586 * infptrace.c (fetch_registers): no result, since now void.
1587 * tconfig/news: target depends on m68k-tdep too.
1589 Fri May 17 14:40:14 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1591 * Makefile.dist: added readline/inc-*.texinfo to dependencies for
1594 * readline/inc-history.texinfo, readline/inc-readline.texinfo:
1595 applied various small fixes due to or inspired by RMS comments
1597 * doc/gdb.texinfo: finished using all RMS comments, save those for
1598 appendices on readline and cmd history (which are in other source
1601 Thu May 16 18:06:05 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1603 * doc/gdb.texinfo: (1) Updated w/ref to RMS comments through
1604 chapter 9; (2) documented 'break' command's menu mode for
1605 overloaded names, in response to hgs problem report C++ p-31
1607 Wed May 15 11:02:48 1991 Roland H. Pesch (pesch at fowanton.cygnus.com)
1609 * doc/gdb.texinfo: (1) better introductory example; (2) more
1610 consistent use of @code, @samp, @file, @kbd throughout; small
1611 cleanups to first three nodes; (3) new "Contributors" node;
1612 (4) Appendix, Renamed Commands; (5) divert specialized startup
1613 instructions to "Targets" chapter for generic manuals, while
1614 leaving them up front for manuals specific to specialized
1615 environments; (6) apply fixes from RMS comments through chapter 4.
1617 * pretex.m4: modify explanatory text slightly (and redefine
1618 "regexp") to keep GNU m4 from complaining. (It still crashes
1619 later, but one step at a time...)
1621 Wed May 15 10:32:12 1991 John Gilmore (gnu at cygint.cygnus.com)
1623 * readline/readline.c (update_line): Avoid dereferencing a pointer
1624 before comparing it to its bounds. Saber caught this.
1625 (init_terminal_io): Don't set BC from the "pc=" termcap variable,
1626 and only set PC if tgetstr returned non-null. Saber caught this.
1628 Tue May 14 16:29:53 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1630 * Makefile.dist: put gdb.dvi stuff (updated to use M4 preprocessor
1631 stuff for config manual) here where it counts; updated
1632 to use new subdir structure (gdb/doc/).
1634 * Makefile: generated from above via
1638 * gdbint.texinfo: added instructions on generating gdb.info* files
1639 locally for release. These are ordinary info
1640 files, formatted from gdb.texinfo (via gdb-all.texinfo, see
1641 Makefile)---but due to use of texinfo 2, can't count on makeinfo
1642 to generate these, so we distribute them already formatted.
1644 * gdb.texinfo: included full Info node and menu crud (as generated
1645 by C-u M-x texinfo-master-menu using the texinfo-2 elisp code).
1647 * Makefile: updated "gdb.dvi" target to use M4 preprocessor;
1648 put in comments-for-future gdb.info target (one day makeinfo will
1651 Tue May 14 13:51:36 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1653 * gdb.texinfo: Updated to include new or old undocumented
1654 commands, at least the following (perhaps some others I forgot to
1655 record): info f, info float, info path, info program, info s, info
1656 set, info source, info terminal, info types, info user, set/show
1658 Also covered all recent GDB command renames for v4.
1660 Mon May 13 14:57:46 1991 John Gilmore (gnu at cygint.cygnus.com)
1662 * mipsread.c: Rather than keeping count of how many symtabs
1663 and psymtabs we have, for sorting purposes, count them when
1664 we need to sort. This fixes bug in rereading of symbol tables.
1666 Fri May 10 15:43:33 PDT 1991 Roland Pesch (pesch at cygint.cygnus.com)
1668 * infcmd.c: renamed "info path" to "show paths"

1683 symtab.h, target.c, target.h: Lint.
1684 * core.c: setup and select frame after reading shared libs,
1685 else reading shared libs will clobber them. Lint.
1686 * utils.c (error): Force out any buffered wrap text.
1688 Fri May 3 22:01:56 1991 John Gilmore (gnu at cygint.cygnus.com)
1690 * remote.c: Remove decls of memory_insert_breakpoint
1691 and memory_remove_breakpoint, no longer used. (Suggestion of
1694 * Makefile.dist: use ${subdir} in paths of BFD and LIBIBERTY,
1695 to make it easier to interface to "configure"'d libraries.
1697 Fri May 3 13:10:01 PDT 1991 Roland Pesch (pesch at fowanton.cygnus.com)
1699 * valprint.c: introduce "set p", "set pr", "show p" and "show pr" as
1700 aliases for set/show print.

2246 Sat Apr 13 14:46:07 1991 John Gilmore (gnu at cygint.cygnus.com)
2248 Permit symbols to be superseded when new symbol files have
2249 been read in, particularly for VxWorks.
2251 * dbxread.c (read_dbx_symtab): Allow N_SOL to cleanly take us back
2252 to the main file, as well as to include files. Also, put global
2253 functions into the global psymtab, to make "i fun" work.
2254 (end_psymtab): Free named symtabs and psymtabs for a file, once a
2255 new psymtab for it has been read.
2256 * coffread.c (end_psymtab): Free named symtabs and psymtabs for
2257 a file, once a new symtab has been read for it.
2258 * mipsread.c: FIXME. We need to do the same for MIPS, but it
2259 looks harder to determine the top-level block before it's been
2260 queued to the psymtab list.
2262 * symfile.c (symbol_file_add): Use filtered printing and wrap it.
2263 If we have wiped out any old symbol tables, clean up at end of
2265 (symbol_file_command): Don't reference symfile_fns if it's zero.
2267 * symtab.h (GLOBAL_BLOCK, STATIC_BLOCK, FIRST_LOCAL_BLOCK): New
2268 defines for the blocks of a blockvector that contain global and
2269 file-static symbols and the first of the smaller scope contours.
2270 * symtab.c (lookup_symbol, find_pc_symtab, find_pc_line,
2271 decode_line_1, make_symbol_completion_list): Use the above.
2272 * coffread.c (end_symtab, patch_opaque_types): Ditto.

2278 * symtab.c (list_symbols): Process the first symbol of the
2279 static psymbols list.
2280 (types_info): Restore this function from its untimely #if 0.
2281 It's not perfect, but it is better than nothing.
2282 (_initialize_symtab): Restore "info types".
2284 Thu Apr 11 05:23:19 1991 John Gilmore (gnu at cygint.cygnus.com)
2286 * m68k-stub.c: Remote stub for 680x0's, created from
2287 rem-m68k.shar (which is removed).
2288 * nindy-share/{Makefile,Onindy.c,blout.h,env.h,nindy.c,ttyflush.c}:
2289 Remove RCS log stuff now that we use CVS and it blows our diffs.
2291 Wed Apr 10 14:18:06 1991 John Gilmore (gnu at cygint.cygnus.com)
2293 * symmisc.c (free_named_symtab): Make it work, in its current
2294 kludgy fashion. Change result to indicate if we blew away bkpts.
2295 * dbxread.c (end_symtab): Accumulate result from
2296 free_named_symtab and print warning if we blew user's state.
2297 * symfile.h: free_named_symtab now returns an int.
2299 Mon Apr 8 23:57:43 1991 John Gilmore (gnu at cygint.cygnus.com)
2301 * dbxread.c (dbx_symfile_read): Initialize psymbol list if this
2302 is the first symbol read, even if not mainline.
2303 (dbx_psymtab_to_symtab): symfile might be zero, cope.
2304 * exec.c (exec_ops): Add_syms_addr is valid in our tvec.
2305 (set_section_command): New command ("section xxx yyy" -- should
2306 be renamed to "set section xxx yyy" FIXME) which sets the
2307 base address of a section of the exec file, overriding the
2308 virtual address that BFD reports.
2310 Fri Apr 5 17:14:39 1991 John Gilmore (gnu at cygint.cygnus.com)
2312 * exec.c: Add add_syms_addr_command to exec_ops, so you can
2313 load symbols at any address while examining an exec file.
2315 Thu Apr 4 10:09:35 1991 John Gilmore (gnu at cygint.cygnus.com)
2317 * tm-i386v.h (FLOAT_INFO): Don't define it, since the code
2318 for printing the float info is host-dependent, not
2319 target-dependent. FIXME.
2320 * i386-pinsn.c: Move #includes to top, remove useless ones.
2321 * i386-tdep.c: Don't bother including <.../reg.h> since we
2322 don't use it (and it doesn't exist on host systems).
2324 * ieee-float.c (ieee_extended_to_double): Convert NaN to Inf.
2325 Convert negative numbers properly.
2326 (ieee_test): Make numbers really random; fix format arg.
2328 * infcmd.c (attach_command, detach_command): Don't repeat on CR.
2329 * core.c (core_detach): Unpush core_ops, which might not be on
2330 top. We used to just pop the top, which broke things. Don't
2331 need dont_repeat() any more.
2332 (core_file_command): Psst! Don't repeat it.
2333 * remote-nindy.c (nindy_detach): Don't need dont_repeat() now.
2334 * expprint.c (print_subexp): Avoid switch fallthru on
2335 BINOP_ASSIGN_MODIFY, so we can print += and such.
2336 * frame.h: Fix typo.
2337 * inflow.c (kill_command): After killing inferior, print our
2338 current frame in the core file, if we have one.
2339 (generic_mourn_inferior): When inferior dies, either select
2340 the current frame (in the new target, e.g. core file), or
2341 set both the current and selected frames to NULL.
2343 Changes from Peter Schauer.
2345 * infptrace.c: Avoid <sys/ptrace.h> on USG.
2347 * Make all file names fit in 14 characters (sigh and damn!):
2348 mv hp300hpux-xdep.c hp300ux-xdep.c
2349 mv symmetry-xdep.c symm-xdep.c
2350 mv symmetry-tdep.c symm-tdep.c
2351 mv convex-opcode.h convx-opcode.h
2352 mv tm-vxworks960.h tm-vx960.h
2353 mv tm-vxworks68.h tm-vx68.h
2354 mv Makefile.srcdir Makefile.sdir
2355 mv gdb-int.texinfo gdbint.texinfo
2356 mv remote-sa.m68k.shar rem-m68k.shar
2357 mv remote-multi.shar rem-multi.shar
2358 * Makefile.dist, README, config.gdb, convex-pinsn.c,
2359 tconfig/symmetry, tconfig/vxworks960, tconfig/vxworks68,
2360 xconfig/hp300hpux, xconfig/symmetry: Change names to shorter
2363 * command.c (user_info_1, user_info): New command for listing
2364 the user-defined commands.
2366 Wed Apr 3 15:00:26 1991 John Gilmore (gnu at cygint.cygnus.com)
2368 * dbxread.c (really_free_pendings): Clear file_symbols
2369 and global_symbols after freeing them; otherwise, running
2370 this function twice (if it appears twice on the cleanup
2371 chain), we try to free things twice.
2373 * dbxread.c (read_dbx_symtab): Calculate end_of_text_addr
2374 based on text_addr (the address of text in core), not on addr (the
2375 offset between text in the .o file and in core). This change
2376 is from Peter Schauer.
2378 * main.c: Define ALL_CLEANUPS as a cast of zero.
2379 (return_to_top_level): Use it.
2380 (main): Do all cleanups after each command run as part
2381 of the gdb startup sequence. Also do all cleanups before
2382 entering the command loop, and every time we exit the command
2383 loop and reenter. Before, the cleanups from the startup sequence
2384 were being left undone until the first error!
2385 (command_loop): Rename do_nothing cleanup to command_loop_marker
2386 so we can see it easily when examining the cleanup chain.
2387 (init_signals): Add another do_nothing for signal handling.
2388 (quit_command): Only try to kill target if it has execution.
2389 Problems in the target stack got us into a state where
2390 inferior_pid was nonzero but none of the targets had execution.
2391 In this state you couldn't exit gdb.
2393 * dbxread.c: Two changes from Peter Schauer.
2394 (echo_command): Fflush output after an echo command.
2395 (show_history): Pass all args to cmd_show_list.
2397 * utils.c (init_malloc): Call mtrace to turn on tracing
2398 if the environment variable MALLOC_TRACE is set to a file name.
2399 * mtrace.c: Add source file which provides a log of every malloc,
2400 free, and realloc to a trace file.
2401 * mtrace.awk: Add source file which analyzes the trace file.
2402 * Makefile.dist (GNU_MALLOC, MALLOCSRC): Add mtrace.{c,o,awk}.
2403 (VERSION): Roll to 3.94.3.
2405 * breakpoint.c (breakpoint_1): Add a space to "i watch" output.
2406 (check_duplicates): Don't bother with watchpoints.
2407 (set_raw_breakpoint): Comment about danger of this routine.
2408 (watch_command): Parse and eval all args before calling
2411 * solib.c (find_solib): Avoid error in referencing memory to
2412 see if any more shared libraries have been added. This is
2413 particularly useful if the target has terminated. Bug reported
2416 Changes from Peter Schauer <pesrem@regent.e-technik.tu-muenchen.de>
2417 in bringing up 3.94.2 on the Sun-3.
2419 * Makefile.dist: Include CFLAGS in rule for cplus-dem.o.
2420 * breakpoint.c (enable_breakpoint): Check for valid watchpoint
2421 expression (in scope) before reenabling watchpoint.
2422 * signame.c (init_sigs): Add missing declaration of i, fix
2423 sys_siglist declaration.
2424 * source.c (list_command): Fixed range computation to use
2426 * stack.c (backtrace_command): Do not allow command if target has
2427 no stack, print informative error message.
2428 * target.c (target_command): Do not write into command line
2429 because this fails if the target command is used in a user defined
2430 command. [This change was enhanced by gnu to support any-
2431 unique-prefix matching on target names.]
2432 * valops.c (value_struct_elt): Avoid infinite loop on an
2433 erroneous attempt to print the member of function (try p main.p).
2435 Mon Apr 1 17:05:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2437 * expread.y (name_no_typename): Avoid reduce/reduce errors
2438 caused by ambiguity in handling NAME_OR_INT and NAME_OR_UINT.
2439 Since the GDB parser really doesn't use name_no_typename in a
2440 name-only context, the parser can't tell the diff between
2441 names and numbers here. Avoid allowing a name_no_typename
2442 to be a NAME_OR_*INT to resolve the conflict.

2446 Bugfixes from Mark Fox (markf@wrs.com) (test=testField.c):
2448 * valprint.c (val_print_fields): bitfield printing didn't handle
2449 byte order. Indirect through a few more fns to cope.
2451 * values.c (modify_field): also cope with byte order.
2453 Sat Mar 23 10:02:21 1991 John Gilmore (gnu at cygint.cygnus.com)
2455 Cleanup for release 3.94.2:
2457 * Makefile.dist: Pull REMOTE_OBS. Fix saber includes for BFD
2458 include files. Roll version to 3.94.2.
2460 * coffread.c (init_stringtab): Read length into unsigned char
2461 array before swapping; don't assume 32-bit longs.
2463 * target.c (target_info): Don't bother with get_sym_file, just use
2464 the symfile global variable.
2465 * symtab.h, symfile.c (get_sym_file): Delete it.
2467 * dbxread.c (dbx_symfile_init): Don't depend on long == 4 bytes.
2468 (define_symbol): Set symbol line number to 0 if not gcc-compiled.
2469 (read_type): Replace one more error() with complain().
2471 * mipsread.c (parse_partial_symbols): Replace printf with complain.
2473 * i960-tdep.c: Fix copyright attribution.
2475 * config.gdb: Quote all backquotes in doublequotes. You can
2476 quote me on that. BSD 4.4 shell found this one.
2478 * infptrace.c (throughout): The third argument to ptrace is an
2481 * infrun.c (wait_for_inferior): When program has terminated, we
2482 have to call target_terminal_ours before we pop that target off
2483 the stack (e.g. before a call to target_kill or
2484 target_mourn_inferior). This fixes problem where a program
2485 terminates, then GDB stops for (tty output) and you have to type
2486 "fg" to the shell to resume it. FIXME: This code for what to
2487 do after termination really should be in normal_stop instead.
2489 * gdbcore.h (read_memory_check): Change declaration; it changed
2492 * terminal.h: Include <sgtty.h> before <sys/ioctl.h>, since in BSD
2493 4.4 prereleases, this avoids a bug in their sgtty compatability
2495 * remote.c: Use terminal.h rather than hand-rolling the same.
2497 * signame.c, signame.h (psignal): Arg is unsigned, not int.
2498 * utils.c (strsave, strstr): Fix arg types.
2499 * valprint.c (val_print): lint
2501 MIPS symbol table support from Per Bothner:
2503 * symfile.c (symtab_fns): Remove initializer table that needs to
2504 be hacked for each new symbol file format supported.
2505 (add_symtab_fns): New function, chains symbol table
2506 handlers into the global list.
2507 (symfile_init): Search this list.
2508 * symfile.h: Add next pointer, declare add_symtab_fns.
2509 * coffread.c (_initialize_coffread): Call add_symtab_fns.
2510 * dbxread.c (_initialize_dbxread): Call add_symtab_fns.
2512 * mipsread.c (psymtab_to_symtab_1): return void instead of (struct
2513 symbol *). Thus, we no longer need the hack to trash
2514 pst->filename. Good, since that hack confused code in symfile.c!
2516 (reorder_symtabs, destroy_all_symtabs): Removed static
2517 all_symtabs, which was used to qsort symtabs in reorder_symtabs.
2518 Instead, the latter now uses a temporary array (stack-allocated
2519 from an obstack, and then freed).
2521 (parse_symbol): Added a hack to fix up BLOCK_{START,END} if they
2522 haven't been set in the outermost stBlock of a procedure. This was
2523 a problem with f77 binaries on Ultrix 4.?.
2525 (new_symtab, new_symbol, new_type): Continue changing code to use
2526 obstacks more and otherwise conform to dbxread internal style.
2527 Made the free_code of symtabs be free_linetable (as in dbxread)
2528 instead of free_contents. This implies memory leaks when reading
2529 a new symbol table, until the conversion is finished. Did change
2530 (struct symbol) and (struct type) to be allocated on the
2531 symbol_obstack. Blocks and blockvectors are among the things
2534 * mipsread.c (parse_partial_symbols, parse_fdr): It hasn't been
2535 tested much, but it solved one problem (reported by Meissner), and
2536 cleans up some other things. The problem happened when an
2537 included file contains actual code (functions) and not just
2538 definitions. The mips coff is a little inconvenient there, since
2539 it may cause a procedure to be mapped to the wrong psymtab.
2541 * mips-tdep.c (heuristic_proc_desc): Minor cleanup.
2542 * mips-xdep.c (fetch_core_registers): Minor cleanup. FIXME,
2543 this will need work for the new core paradigm.
2545 Opcode patches from the net:
2547 * mips-opcode.h: fix incorrect disassembly of the mfc1, cfc1, and
2548 ctc1 instructions. Also, the cvt.d.w and cvt.s.w instructions were
2549 missing altogether - they are added here. From Bruce Bauman.
2550 * mips-opcode.h: The low mask for C0 instructions was too small.
2551 From Garrett Lau. I modified the fix to check the entire 32-bit
2554 * ns32k-opcode.h: Fix opcodes for deiw and deid. From Bruce
2557 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2559 Roll in changes from Per Bothner (Tue, 25 Sep 90 11:11:04):
2561 * dbxread.c (read_type): Pointer subtraction (value_sub in
2562 valarith.c) sometimes failed because the types of the
2563 pointers being subtracted were not identical.
2564 These differed because dbxread.c was allocating pointer types
2565 using dbx_alloc_type+smash_to_pointer_type instead of
2566 lookup_pointer_type. I failed to find a justification for the
2567 former, so I changed it to use the latter. Similarly, I
2568 replaced smash_to_function_type by lookup_function_type,
2569 and smash_to_reference_type by lookup_reference_type.
2571 * mipsread.c (parse_symbol, upgrade_type, parse_procedure,
2572 _initialize_mipsread): corresponding changes.
2574 * symtab.c (smash_to_{pointer,reference,function}_type): eliminate.
2576 * source.c (mod_path): Do tilde_expand on each component of the path,
2577 rather than on the (list of) paths as a whole.
2578 (print_source_lines): Set first_line_listed in addition to
2579 current_source_symtab and current_source_line. If the source was
2580 not findable, after a "dir" command to fix the problem,
2581 a "list" would get the wrong lines.
2583 While I was there... (gnu):
2585 * dbxread.c (read_type): Change error to complaint.
2587 Thu Mar 21 12:56:46 1991 John Gilmore (gnu at cygint.cygnus.com)
2589 First attempt at detailed understanding of symbol table memory alloc.
2591 * dbxread.c (dbx_symfile_read): Free our string table if we
2592 aren't the mainline. Free the "info" struct since we're done with
2594 (init_psymbol_list): Free any previously allocated psymbol lists.
2595 (): FIXME: Should realloc-down the psymbol lists when done reading
2596 the main symbol file?
2598 * symmisc.c (free_symtab): Free fullname field too.
2600 * xm-hp300hpux.h (USG): #undef then #define so Makefile can -D.
2601 (REGISTER_ADDR): Make result type unsigned int.
2603 * xconfig/{i386*,hp300hpux,altosgas,altos}: All config files that
2604 define REGEX must also define REGEX1 (its dependency).
2606 Tue Mar 19 21:28:57 1991 John Gilmore (gnu at cygint.cygnus.com)
2608 * tconfig/i960: No longer works, points you at vxworks960 or
2611 * xgdb.c, XGDB-README: Remove file. Users can get the much
2613 * Makefile.dist: Remove all trace of xgdb.
2615 * breakpoint.c (breakpoint_1): Pass demangle arg to
2616 print_address_symbolic.
2617 (clear_breakpoints): Remove unused function.
2618 (breakpoint_re_set_one): Guts of breakpoint_re_set.
2619 (breakpoint_re_set): Use catch_errors to do them all anyway.
2621 * gdb-int.texinfo (Host versus Target): Add section on what is
2622 a "host" feature versus what is a "target" feature.
2624 * infcmd.c (path_command, path_info): Handle the PATH variable
2625 (object search path) as conveniently as the source search path.
2626 * environ.c (set_in_environ): Set some vars in GDB's environment,
2627 in addition to the child's. PATH, G960BASE, G960BIN for starters.
2628 * source.c (mod_path): New function, from guts of
2629 directory_command, modifies a path. Used by path_command.
2630 (directory_command): Call it.
2631 * defs.h (strsave): Declare.
2633 * utils.c (sevenbit_strings): Add new printing option.
2634 (printchar): Use it.
2635 (strsave): Provide this handy helper routine.
2636 (set_width_command): Rename set_screen_width_command.
2637 (_initialize_utils): "set screen-width" => "set width";
2638 "set screen-height" => "set height"; add sevenbit-strings.
2640 * infcmd.c (do_registers_info): Print floating point registers
2641 in raw hex as well as float format, regardless of whether it is
2642 a "virtual" convertible register.
2643 * tm-sparc.h (PRINT_REGISTER_HOOK): Print every pair of float
2644 regs as a double, just in case it's being used that way.
2645 * values.c (unpack_long): Comment on array/function coercion.
2646 (unpack_double): Argument is in target byte order now. For
2647 integer arguments, just call unpack_long and float the result.
2648 * m68k-tdep.c: include defs.h for "const" handling.
2649 * remote-nindy.c: Use ieee-float stuff.
2650 (nindy_fetch_registers): Unpack double regs to host double, then
2652 (nindy_store_registers): Pack extendeds to host double, flip
2653 around by misusing unpack_double, send as target double.
2655 * tm-vxworks68.h (FRAME_CHAIN): Handle current frame pointer of
2656 zero, as when stopped at the first instruction of a process.
2658 * blockframe.c: Fix filename in comment (param.h => tm.h).
2659 * sparc-tdep.c (skip_prologue): More explicit nudging comments.
2660 * tm-68k.h: Fix typos.
2662 Fri Mar 15 01:09:34 1991 John Gilmore (gnu at cygint.cygnus.com)
2664 Changes from a bringup on the DEC Vax under Ultrix 4.0.
2666 * coredep.c (fetch_core_registers): Pass end-address of register
2667 section to register_addr as expected. Don't call supply_register
2668 if we'd just pass it garbage.
2670 * dbxread.c (read_dbx_symtab): Skip N_NSYMS on Ultrix.
2672 * exec.c (xfer_memory): Use boolean xfer_fn result, not int.
2674 * target.c (push_target, target_info): Cast enums to int for < or
2677 * stack.c (print_frame_info): Identify source file & line
2678 even if we can't print it.
2680 * xm-vax.h (MISSING_VPRINTF): No longer missing in Ultrix V4.0.
2682 Sat Mar 9 10:08:20 1991 John Gilmore (gnu at cygint.cygnus.com)
2684 Clean up IEEE floating point support.
2686 * ieee-float.h: New file.
2687 * ieee-float.c: Write real routines to convert between host
2688 doubles and various target IEEE extendeds.
2689 * m68k-xdep.c: Eliminate assembler code for extended floats.
2690 * xconfig/{3b1,altos,altosgas,hp300bsd,isi,news,news1000,sun2os3,
2691 sun2os4,sun3,sun3os3,sun3os4}: Eliminate use of m68k-xdep.o.
2692 * tm-i960.h, tm-68k.h (REGISTER_CONVERT_TO_VIRTUAL,
2693 REGISTER_CONVERT_TO_RAW): Use ieee_extended_to_double and
2694 double_to_ieee_extended.
2695 * i960-tdep.c: Define ext_format_i960.
2696 * m68k-tdep.c: Define ext_format_68881.
2697 * sparc-tdep.c: Define ext_format_sparc, though unused.
2698 * Makefile.dist (HFILES): Add ieee-float.h.
2699 * inftarg.c: #include "ieee-float.h" for the REGISTER_CONVERT
2702 Obsolete the "coffstrip" program in favor of using BFD's strip.
2704 * nindy-share/coffstrip.c: Remove file.
2705 * nindy-share/nindy.c (coffstrip): Routine to run bfd_strip.
2706 * Makefile.dist: Remove references to nindy-share/coffstrip.c.
2707 * tconfig/nindy960: Remove reference to coffstrip.o.
2709 * Makefile.dist: Roll version number to 3.94.1 (not yet final).
2711 Wed Mar 6 09:56:45 1991 John Gilmore (gnu at cygint.cygnus.com)
2713 * symfile.h: Add symfile_bfd, common between dbxread and coffread.
2714 * dbxread.c: Remove static symfile_bfd.
2715 * infcmd.c (do_registers_info): Add PRINT_REGISTER_HOOK, though
2717 * inftarg.c (child_detach): Pop the child_ops vector if the
2718 detach is successful.
2719 * remote-nindy.c (nindy_create_inferior): Don't push a new
2720 nindy_ops since nindy uses the same one for execution and memory
2722 * core.c (core_ops): Use child_attach and child_create_inferior
2723 rather than default attach and create_inferior functions.
2725 Handle floating point registers in core files.
2727 * sparc-xdep.c (fetch_core_registers): Rewrite for float support.
2728 * sun3-xdep.c (fetch_core_registers): Rewrite for float support.
2729 This version untested since BFD doesn't yet support sun3 core
2731 * hp300hpux-xdep.c: Rewrite fetch_core_registers to new calling
2732 conventions. Fix comments and style. This version has not
2733 been compiled yet, since we have no HP inhouse.
2734 * core.c (get_core_registers): Look for two sections, ".reg"
2735 and ".reg2", and pass both to fetch_core_registers sequentially.
2737 Revise directory path yet again.
2739 * source.c (forget_cached_source_info): Not static any more.
2740 (init_source_path): New default source path is "$cdir:$cwd".
2741 (dir_command): Handle variable arguments ($cdir, $cwd).
2742 (source_info): Print "Compilation directory" rather than
2743 "Originally compiled in" to remind people of $cdir.
2744 (openp): If the path contains $cwd, use current directory.
2745 (open_source_file): If compilation directory is known, replace
2746 first $cdir in path with the compilation directory.
2747 (print_source_lines): Even if we can't print the lines, set the
2748 current symtab and line for future commands like "info source" or
2749 "breakpoint". Also, error message now contains the file name,
2750 line number, and file access error message.
2751 (_initialize_source): Fix help text to describe changes.
2752 * main.c (cd_command): Forget cached source info when we chdir.
2753 * utils.c (strstr): Add simple implementation.
2755 Tue Mar 5 01:41:40 1991 John Gilmore (gnu at fowanton.cygnus.com)
2757 * coffread.c (read_one_sym, init_linetable, init_stringtab):
2758 Byte-swap COFF symbol tables if necessary when reading them in.
2759 Use complain() to replace error message in one spot. Needs
2760 corresponding change in bfd/coff-code.h to make some symbol
2761 swapping routines non-static.
2763 Mon Mar 4 00:53:40 1991 John Gilmore (gnu at cygint.cygnus.com)
2765 Merge changes from Eirik Fuller, for UTek.
2767 * defs.h (errno): Add declaration.
2768 * altos-xdep.c, arm-xdep.c, convex-xdep.c, gould-xdep.c,
2769 hp300hpux-xdep.c, infrun.c, inflow.c, infptrace.c, i386-tdep.c,
2770 i386-xdep.c, pyr-xdep.c, mips-xdep.c, remote-eb.c, remote-nindy.c,
2771 remote-vx.c, source.c, standalone.c, stuff.c, sun386-xdep.c,
2772 symmetry-tdep.c, symmetry-xdep.c, umax-xdep.c, utils.c: Eliminate
2773 declarations of errno.
2775 * remote-eb.c: Define B19200 and B38400 as EXTA and EXTB.
2777 * remote-vx.c: Include <sys/time.h> for UTek; Sun gets it via
2778 <rpc/rpc.h> and <rpc/types.h>.
2780 Sat Mar 2 15:47:55 1991 John Gilmore (gnu at cygint.cygnus.com)
2782 * i960-tdep.c (examine_prologue): Add new argument limit,
2783 which stops the scan at the end of the prologue, or at the PC.
2784 This fixes a problem where it walks down into the code for the
2785 user's statements if that code looks like function prologues.
2786 Mark Fox and I have been bouncing this code back and forth, making
2787 small changes to it. Callers changed to match.
2789 Tue Feb 26 01:47:07 1991 Cygnus John Gilmore (cygnus at yuba)
2791 Cleanup for gdb-3.94 release final:
2793 * Makefile.dist: Remove remote-vx.c, remote-nindy.c, and all
2794 the .c files from vx-share and nindy-share, from the various
2795 macros, since they are not found via ALLDEPFILES.
2796 (SFILES): Add tm-i960.h.
2797 (alldeps.mak rule): Break out ALLDEPFILES_MAINDIR and
2798 ALLDEPFILES_SUBDIR. List all the nindy and vxworks subdir files
2800 (TAGFILES_MAINDIR): Change ALLDEPFILES to ALLDEPFILES_MAINDIR.
2801 (gdb.tar.Z): Use ALLDEPFILES_SUBDIR as well as SFILES_SUBDIR.
2803 Mon Feb 25 16:02:35 1991 Cygnus John Gilmore (cygnus at oldman)
2805 * am29k-tdep.c: Add contribution line.
2806 (examine_prologue): Cache information about function prologues in
2807 the misc-function-vector to avoid lots of references over the
2808 serial line while examining instructions.
2810 * core.c (core_close): New function made from cleanup_core.
2812 * core.c, exec.c, inftarg.c, remote-eb.c, remote-nindy.c,
2813 remote-vx.c, remote.c, target.c, target.h,
2814 Update target_ops vector to add attach, close, and load entries.
2815 Use add_syms_addr_command, not add_file_addr_command, for
2816 add_file. Break out close routine from existing code.
2818 * dbxread.c (really_free_pendings): Don't free pending_blocks;
2819 they are in an obstack.
2820 (read_dbx_symtab): Relocate end_of_text_addr in the psymtab.
2822 (define_symbol): Add symbol type parameter; change callers;
2823 pass type parameter to DBX_PARM_SYMBOL_CLASS macro to allow
2824 it to influence the symbol class on the i960.
2825 (define_symbol): Swap LOC_CONST's into target byte order.
2827 * exec.c (exec_close): New function.
2828 (exec_file_command): Call it.
2830 * findvar.c (read_relative_register_raw_bytes): Doc byte order,
2831 Fix byte order of frame pointer.
2832 (read_var_value): Result of 0 if var's value can't be found,
2833 e.g. missing FRAME_ARGS_ADDRESS. Byte-swap LOC_CONST and
2834 LOC_LABEL values to target order. Add LOC_LOCAL_ARG.
2835 (locate_var_value): Use read_var_value and use its lazy address
2836 as the location of the var's value. Lint.
2838 * i960-pinsn.c (next_insn): Add routine from vxgdb for scanning
2841 * i960-tdep.c (arg_address, i960_frame_find_saved_regs): Remove
2842 obsolete Intel versions in favor of vxgdb versions.
2843 (check_host, byteswap, byteswap_val, reorder_val): Eliminate
2844 code dealing with byte order of values, which Intel did in host byte
2845 order rather than gdb-4's target byte order.
2846 (i960_frame_chain_valid): Move to nindy-tdep.c.
2847 (examine_prologue, skip_prologue, frame_find_saved_regs,
2848 frame_args_address, leafproc_return, saved_pc_after_call,
2849 pop_frame): Add vxgdb versions from Mark Fox.
2850 (examine_prologue, frame_struct_result_address): Add code
2851 to deal with the saved value of G13 (struct return address
2853 (frame_args_address): Modify Mark's version to prefer the
2854 saved value over the current value in the topmost frame.
2855 Cache result in the frame info to avoid performance hair in
2857 (print_fault): Add gdb960 code for printing faults.
2858 (_initialize_i960): Actually call check_host.
2860 * ieee-float.c (ieee_extended_to_double, ieee_double_to_extended):
2861 add stub routines. FIXME, these currently just return zero!
2863 * infcmd.c (program_info): Use PRINT_RANDOM_SIGNAL.
2864 (attach_command): Call target_attach, not target_open, now.
2866 * infrun.c (normal_stop): Make global, not static, for vx_attach.
2867 (child_attach): Rename from child_open.
2868 (wait_for_inferior): Use PRINT_RANDOM_SIGNAL. If stop_pc is zero,
2869 don't confuse it with a zero step_resume_break_address.
2871 * inftarg.c (child_detach): Eliminate inferior_pid test.
2872 (child_files_info): Clean up message a bit.
2873 (child_ops): Use child_attach, not child_open, to attach.
2875 * mem-break.c: #ifdef out the whole file if BREAKPOINT is not
2876 set (e.g. on VxWorks or NINDY). Move read_memory_nobpt from
2877 findvar.c to here, since it depends on the contents of the
2878 shadow_contents of breakpoints, but keep if #if 0 since it is
2881 * nindy-tdep.c: New file, contains nindy_frame_chain_valid, moved
2884 * printcmd.c (address_info): Handle LOC_LOCAL_ARG. Lint.
2885 (ptype_command, display_command): Eliminate have_inferior_p and
2886 have_core_file_p in favor of target_has_stack or
2887 target_has_execution.
2888 (print_frame_args): Handle LOC_LOCAL_ARG. Eliminate duplicate
2889 code for actually finding the values of arguments, though we still
2890 keep track of the maximum stack offset for use in printing unnamed
2891 arguments. Handle missing FRAME_ARGS_ADDRESS.
2893 * remote-nindy.c (i960_print_fault): Move to i960-tdep.c.
2894 (struct nindy_regs): Define registers passed to/from nindy.
2895 (nindy_fetch_registers, nindy_store-registers): Translate between
2896 nindy and GDB formats for the registers.
2897 (dcache_init): Statically allocate the cache, since it was being
2898 allocated by a malloc that was never freed anyway.
2899 (nindy_create_inferior): Error, not core dump, if no exec file.
2900 (nindy_before_main_loop): Use target_load, not target_add_file.
2902 * remote-vx.c (net_load): Specify large timeout for load
2903 requests. Allow user to break out with INTERRUPT.
2904 (net_break): Remove useless code, clean up. Change callers.
2905 (parse-args, skip_white_space, find_white_space): Clean up arg
2906 parsing to cope with quoted strings.
2907 (net_wait, net_quit): Never call error, just return status.
2908 (vx_read_register, vx_write_register): Cleanup status checking.
2909 #ifdef the code based on which CPU we are using (960 or 68k),
2910 FIXME, this should be completely general but it isn't yet.
2911 (vx_xfer_memory, vx_resume): Cleanup status checking.
2912 (vx_run_files_info): Improve message.
2913 (vx_load_command): Renamed from vx_add_file_command. Allow load
2915 (net_ptrace): Remove unused routine.
2916 (vx_wait): Adopt code from vxgdb960 to cope with broken
2917 connections to target machine and prompt to disconnect. Remove
2918 debug printouts. Map some EVENT_'s to SIGnals.
2919 (add_symbol_stub, vx_open): Print names of object files we found,
2920 and "ok" if we read their symbols OK. Clarify output in general.
2921 (vx_attach, vx_detach, vx_kill): Add these commands.
2922 (vx_convert_from_virtual, vx_convert_to_virtual): Simplify.
2923 (vx_run_ops): Turn off all_mem, to avoid spurious msg in the
2924 "info files" output, and create_inferior, since we already have
2927 * stack.c (frame_info): Replace Frame_unknown with 0.
2928 (print_frame_arg_vars): Handle LOC_LOCAL_ARG.
2929 (return_command): Pop until the PC matches as well as the FP,
2930 so it works even if the FP is shared with another function,
2931 as in "frameless" or "leaf" procedures.
2933 * symfile.c (load_command): renamed from add_file_target_command.
2934 (add_syms_addr_command): renamed from add_file_addr_command.
2935 (add_syms_command): Stub to call target_add_syms.
2936 (_initialize_symfile): Change command names and descriptions,
2937 add-file => add-syms, and load from alias to its own command.
2939 * target.c (kill_or_be_killed, maybe_kill_then_attach,
2940 maybe_kill_then_create_inferior): Default for attempts to start
2941 a process, if one is already running, is to ask about killing
2942 it and retry if yes.
2943 (upstack_create_inferior): #if-0 it, strata obsolete it.
2944 (push_target, unpush_target, pop_target): to_close() a target
2945 before unstacking it.
2946 (target_info): Renamed from target_files_info.
2947 (_initialize_targets): Rename "i files" as "i target", accessible
2950 * target.h: Improve comments about the target_ vectored routines.
2952 * tm-i960.h: Remove NINDY-specific stuff to tm-nindy960.h.
2953 Convert commenting style to standard GNU style.
2954 (DBX_PARM_SYMBOL_CLASS): allow LOC_LOCAL_ARG's to be recognized.
2955 (SKIP_PROLOGUE): No longer a no-op.
2956 (SAVED_PC_AFTER_CALL): Now handles leaf procedures.
2957 (*_REGNUM): Sort register numbers.
2958 (REGISTER_BYTES, REGISTER_BYTE, REGISTER_RAW_SIZE,
2959 MAX_REGISTER_RAW_SIZE, REGISTER_CONVERTIBLE,
2960 REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW): Float regs
2961 are now 10 byte extendeds, not 8 byte doubles.
2962 (FRAME_CHAIN_VALID): Make this config-dependent, since it differs
2963 for nindy versus vxworks targets. FIXME, this should possibly go
2964 in the target vector.
2965 (EXTRA_FRAME_INFO, INIT_EXTRA_FRAME_INFO): Cache both
2966 frame_saved_regs and arg pointer with each frame.
2967 (FRAMELESS_FUNCTION_INVOCATION): New leafproc support.
2968 (FRAME_ARGS_ADDRESS): Use cached result.
2969 (FRAME_ARGS_ADDRESS_CORRECT): New, avoids g14 guessing.
2970 (FRAME_FIND_SAVED_REGS): Change arg to subsidiary fn.
2971 (PRINT_RAMDON_SIGNAL): Call print_fault.
2972 (POP_FRAME): Now works.
2974 * tm-nindy960.h: Break this off tm-i960.h. NINDY-specific
2975 option parsing and startup; STACK_END_ADDR, FRAME_CHAIN_VALID,
2976 BREAKPOINT, and DECR_PC_AFTER_BREAK are here.
2977 (ADDITIONAL_OPTION_HANDLER): use target_load, not
2980 * tm-vxworks960.h: Break this off tm-i960.h. VxGDB specific
2981 startup; DECR_PC_AFTER_BREAK, and FRAME_CHAIN_VALID are here.
2983 * valarith.c (value_subscripted_rvalue): Avoid handling
2984 floats and doubles specially; it gave alignment errors. Lint.
2986 * valops.c (value_of_variable, value_of_this): Error if unknown
2989 * valprint.c (print_floating): Bcopy rather than pointer-deref,
2990 to avoid alignment problems.
2991 (value_print): Handle unknown value address.
2992 (cplus_val_print): Two args are ignored; remove them. Change caller.
2993 (val_print): Use unpack_long rather than pointer-deref.
2996 (unpack_long, unpack_double): Use bcopy rather than pointer-deref
2997 to avoid alignment problems.
2998 (value_being_returned): Error if return value unknown.
2999 (set_return_value): Add bogosity warning, FIXME. *
3001 * TODO: A woman's work is never done.
3003 * Makefile.dist: Distribute REMOTE_OBS into tconfig files.
3004 Separate INCLUDE_CFLAGS for use with lint. Add LINTFILES.
3005 Add ieee-float.o to OBS.
3006 * tconfig/{nindy960,vxworks68,vxworks960}: Include the desired
3007 REMOTE_OBS remote-interface files in the TDEPFILES and TM_FILE.
3008 * tconfig/i960: FIXME. Half-merge, produce warning if config'd.
3010 Changes to generalize the VxWorks RPC protocol slightly, to handle
3011 i960 as well as 68000.
3013 * vx-share/dbgRpcLib.h (VX_SOURCE_STEP): Add.
3014 * vx-share/reg.h: Produce i960 regs #ifdef I80960
3015 * vx-share/xdr_ptrace.c: Skip FPA registers if 960.
3016 * vx-share/xdr_rdb.h: Add SOURCE_STEP struct and xdr decl.
3017 * vx-share/xdr_rdb.c: Add xdr_SOURCE_STEP routine.
3018 * vx-share/xdr_regs.c: Add xdr_regs, xdr_fp_status, xdr_ext_fp
3019 for i960. Change xdr_vectors to xdr_opaques for 68k registers,
3020 so they will move in target byte order rather than network
3021 byte order (happens to be the same).
3023 Mon Feb 25 03:41:44 1991 John Gilmore (gnu at cygint.cygnus.com)
3025 * tm-convex.h (END_OF_TEXT_DEFAULT): Remove #if 0'd block.
3027 Sun Feb 24 00:55:53 1991 John Gilmore (gnu at cygint.cygnus.com)
3030 Add contribution lines to various files, showing where they
3033 * breakpoint.c (break_insn, check_break_insn_size,
3034 read_memory_nobpt): Remove to mem-break.c.
3036 * xm-*.h, param-no-tm.h, tm-29k.h, valprint.c: Change BYTE_ORDER to
3039 * tm-29k.h (STAB_REG_TO_REGNUM): Warn user if symbol table
3040 entry has bad register number. This change is not
3041 tested in this release, FIXME.
3043 * frame.h: Eliminate Frame_unknown in favor of a simple zero.
3046 * value.h: Force value's contents field to be aligned to hold
3047 at least a double or a long long (if supported). This avoids
3048 doing bcopy's in and out of the contents field.
3050 (step_1): Avoid coredump under obscure circumstances when we
3053 * symtab.h (misc_info): Add field to misc function vector for
3054 any kind of cached information the target code desires. AMD
3055 29000 uses this to avoid repeating examine_function_prologue's.
3057 * coffread.c: Lint. Remove static symfile, read_section_header.
3058 core.c (have_core_file_p): Lint: remove.
3059 expprint.c (print_subexp): Lint.
3060 infptrace.c, valops.c, valprint.c: lint.
3062 Roll in changes from vxgdb-5.0.1:
3064 * symtab.h: Comment byte order of each address class. Add
3065 LOC_LOCAL_ARG for frame-relative args (960).
3066 expread.y: Use LOC_LOCAL_ARG where LOC_ARG is used.
3067 symtab.c, symmisc.c: ditto.
3069 * infrun.c (init_wait_for_inferior): Clear stop_signal.
3071 * remote.c (remote_resume): Error if resume with a signal.
3073 * symfile.c (prim_record_misc_function): Clear misc_info.
3074 (fill_in_vptr_fieldno): Check stub type of arg.
3076 * valops.c (value_cast): Avoid looking up names of types whose
3077 name we don't know, to prevent coredump. Sun CC produces typedef
3078 rtx and the name of *rtx is zero...
3080 Mon Feb 18 21:16:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3082 Roll in changes from final AMD 29000 port (Tiemann).
3084 tconfig/am29k: Add COFF_ENCAPSULATE and TARGET=TARGET_AM29K
3085 for ../include/a.out.encap.h. This might not work now that BFD
3086 is separately compiled. Instead, BFD support for encap will have
3087 to translate machine type 29k into the right COFF_MAGIC.
3089 * infcmd.c: Remove references to inferior_pid that aren't used
3090 in actual ptrace calls; use target_has_execution, etc.
3091 (have_inferior_p): Remove function.
3092 (program_info): Print target info rather than "process number";
3093 avoid gratuitous messages unless from_tty.
3094 (run_stack_dummy, finish_command): Set proceed_to_finish.
3095 infrun.c: Remove inferior_pid refs. Decl & init proceed_to_finish.
3096 main.c: Lint. Lose have_inferior_p().
3097 inferior.h (have_inferior_p): Remove, lint.
3098 (proceed_to_finish): Add flag to ask that all regs be saved
3099 by normal_stop, for the few commands that need it, speeding up
3100 serial I/O. Add comments to stop_registers.
3102 * remote-eb.c: Remove newline from breakpoint message we grep
3103 for. Never time out when running the user program.
3107 Wed Feb 13 15:34:40 1991 John Gilmore (gnu at cygint.cygnus.com)
3109 Roll in changes from vxgdb-5.0.1:
3111 * dbxread.c (read_dbx_symtab): If we encounter a "FORTRAN COMMON"
3112 symbol in its raw form, we are processing an unlinked ".o" file.
3113 See if the target environment has assigned it an address, using
3114 target_lookup_symbol (VxWorks does), and enter it into the symtab
3117 * tm-vxworks.h (FRAME_CHAIN, FRAME_CHAIN_VALID): Override usual
3118 68k versions for a simpler version that assumes zero FP at bottom.
3119 Fixes bug of truncated stack reports.
3121 * target.h (target_lookup_symbol): Define this routine's args
3122 and result, finally.
3124 * target.c (nosymbol): Default routine for target_lookup_symbol.
3125 (target_default): Default lookup_symbol and call_function too.
3126 (files_info): Only print has_all_memory warning if a non-dummy
3129 * remote-vx.c (vx_read_register, vx_convert_to_virtual,
3130 vx_convert_from_virtual): If target does not have floating point,
3131 zero register "values", and avoid doing cross-net conversions.
3132 (vx_lookup_symbol): Rename net_lookup_symbol, add to vectors.
3133 (vx_open): Rearrange code that attaches to target and reads
3134 symbols for all loaded modules, to work if some of the modules
3135 are not accessible. Add symbol_stub() and add_symbol_stub()
3136 as callbacks from catch_errors(). Allow connect attempt to be
3137 interrupted painlessly with ^C (FIXME, there are still some bugs
3138 if the interrupt happens during symbol reading.). Print
3139 final message with puts_filtered, since symbol messages are
3144 * main.c (catch_errors): Only print errstring if non-null.
3145 (command_loop): Avoid an ioctl per command to test ISATTY.
3147 * remote-vx.c (net_load): make static; avoid sophomoric msg.
3148 (vx_xfer_memory): Return correct result!
3149 (vx_files_info): Indicate whether target has float or not.
3150 (vx_lookup_symbol): Complain, not error, if target gone.
3151 (vx_open): Print "Connected" msg before disabling immediate-quit.
3152 [FIXME: lookup_symbol and vx_open changes need testing.]
3154 target.c, remote-eb.c, inftarg.c, am29k-opcode.h, target.h,
3155 tm-29k.h, tmm-vxworks68.h, symfile.c, gdb-int.texinfo: Add
3156 contributor lines and update copyrights to 1991.
3158 Changes from an attempted H-PUX host port:
3160 * infptrace.c (PT_ATTACH, PT_DETACH): Handle HP/UX, which
3161 defines PT_ATTACH and PT_DETACH but not PT_KILL.
3162 * remote-eb.c (eb_open): Misplaced endif kills sysv H/PUX.
3163 * remote-vx.c: include <sys/time.h> for HPUX.
3164 * hp300hpux-xdep.c (fetch_core_registers): Rewrite old
3165 "core_file_command" routine to BFD regime. May not work yet.
3167 Attempted port of "gdb-3.4 Van Jacobson xgdb" to modern gdb.
3169 * xgdb.c: Replace X10 version with some VJ version.
3170 (FIXME: Its copyright assignment is not on record.)
3171 * xgdb.c: Update include files to X11R4 (Xaw crud).
3172 (xgdb_display_source, create_text_widget): fix call to
3173 get_filename_and_charpos. Rewack source window stuff for X11R4
3174 (gleaned from include files, and "nm's" of binary libraries, since
3175 I had no doc available).
3176 (append_selection, append_selection_word): Disable with FIXME
3177 since R4 changed interface here.
3178 (create_buttons): Add back the old set of buttons.
3179 (xgdb_create_window): Fix call to XtInitialize (&argc not argc).
3181 * Makefile.dist (xgdb, xgdb-init.c): Update for X11R4 on Suns.
3182 Roll VERSION to 3.94 (not yet final though).
3184 Sat Feb 9 09:46:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3186 * obstack.h (obstack_ptr_grow, obstack_ptr_grow_fast,
3187 obstack_int_grow, obstack_int_grow_fast): Eliminate
3188 cast on left of assignment, which gives MIPS cc fits and is
3191 * sparc-pinsn.c (print_insn): Eliminate 'set' test, subsumed by
3192 F_ALIAS. Use printf, not fprintf, when not passing a file
3194 (compare_opcodes): Check that identical instructions have
3195 identical opcodes, complain otherwise.
3197 * sparc-opcode.h (st %fsr): Fix opcode "lose" mask. This
3198 was reported by Roland McGrath.
3199 (unimp): Only match if exactly zero instruction. (Roland)
3200 (branches and traps): Generate all variations of these
3201 instructions with macros, based on a single call that defines
3202 each condition name and its binary representation.
3203 (set): Turn on alias bit, to avoid test in sparc-pinsn.c.
3205 * valprint.c (val_print_fields): Take, and use, format parameter.
3206 This means that "p/x struct" again prints the elements in the
3207 desired format. Changed callers.
3209 * stack.c (frame_info): Use filtered output, and indicate wrap
3210 points. Remove kludgy formatting designed to avoid line wrap.
3212 * utils.c (wrap_here): If the line is already full (because
3213 we had printed a long indent or long wrapped string), do an
3214 immediate newline-and-indent.
3216 * m68k-pinsn.c (print_insn_arg): Bugfix from
3217 ntmtv!thompson@ames.arc.nasa.gov (Mike Thompson): 'bkpt #0'
3218 instruction is incorrectly disassembled as bkpt #8.
3220 * dbxread.c (end_psymtab): Bugfix from Peter Schauer
3221 <pesrem@regent.e-technik.tu-muenchen.de>: If you want to set a
3222 breakpoint in a *.y file gdb will say Reading in symbols for *.y...
3223 and then will dump core (sometimes). I traced it back to an
3224 uninitialized symfile_name in psymtab_to_symtab.
3225 (const_vol_complaint): Add quotes to message.
3226 (define_symbol): Only believe line number if gcc_compiled.
3227 Avoid allocating symbol if we will not return it.
3229 Add target strata support so that newly established targets go
3230 into their right place in the target stack (e.g. a new exec file
3231 doesn't wipe out the ability to access the running process).
3233 * target.h, core.c, exec.c, inftarg.c, remote-eb.c,
3234 remote-nindy.c, remote-vx.c, remote.c, target.c: Add to_stratum
3235 and initialize it properly in all the targets.
3237 * target.h: Document strata. Change return type of push_target.
3239 * target.c (nomemory): new function for dummy memory access.
3240 (tcomplain): Rename complain, now also used in symfile.c.
3241 (push_target): Push targets within strata. New return value shows
3242 whether new target is on top of stack or not. Always keep dummy
3244 (target_files_info): Ignore dummy target.
3246 * core.c (core_open): Warn user, and skip accessing file, if the
3247 core target is not the topmost target in the stack.
3248 * remote-nindy.c (nindy_create_inferior): Avoid unpush_target, now
3251 * remote-vx.c: Remove vx_prepare_to_store from vxworks memory
3252 target_ops, it doesn't belong there since we have no regs there.
3253 Change name of target from machine => memory to clarify.
3255 Thu Feb 7 16:32:09 1991 John Gilmore (gnu at spiff.cygnus.com)
3257 * Freeze version 3.93 for release.
3259 * Makefile.dist: Handle vx-share and nindy-share subdirs
3260 properly when building gdb.tar.Z.
3262 * symtab.c: lint; add no_symtab_msg to consolidate the messages
3263 printed in various places, so I could change just one copy.
3265 * dbxread.c, coffread.c: Change references to bfd->iostream
3266 to cast to FILE *, now that BFD avoids needing types defined
3267 in other header files.
3269 Tue Feb 5 21:39:35 1991 John Gilmore (gnu at cygint.cygnus.com)
3271 * command.c, dbxread.c, expprint.c, infcmd.c, infptrace.c,
3272 infrun.c, printcmd.c, remote-nindy.c, source.c, sparc-tdep.c,
3273 sparc-xdep.c, symfile.h, symmisc.c, utils.c, valprint.c: Lint
3274 (actually gcc -Wall).
3276 * dbxread.c: Remove first_global_sym, last_global_sym, since
3277 they are never referenced.
3279 * defs.h (baud_rate): Declare.
3280 main.c: Define it, and add the -b option to set it.
3282 * gdb-int.texinfo: Add text on how to define a new host or target
3283 architecture, prompted by Per Bothner's questions about MIPS
3286 * gdb.texinfo: Document "complaints". Change doc of -q since
3287 gdb no longer prints the copyright and blurb if you specify a file
3288 name to be debugged (just like Emacs). Add doc for Nindy-specific
3289 command line flags for specifying target serial port and such.
3290 Update copyright to 1991.
3292 * gdbcore.h: Remove a large mass of now-useless crud, since BFD
3293 has taken over for us the job of ripping up executable files. The
3294 crud caused Per Bothner's port to not compile.
3296 * infrun.c (normal_stop): Avoid printing "Program exited
3297 normally" if we are in batch mode. This allows a GDB which
3298 executes a program on a target system, to behave like a Unix
3299 command (input from stdin, output to stdout, no extraneous
3302 * main.c (main): Allow additional machine-dependent command line
3303 options to be specified with the ADDITIONAL_OPTIONS,
3304 ADDITIONAL_OPTION_CASES, ADDITIONAL_OPTION_HELP, and
3305 ADDITIONAL_OPTION_HANDLER macros. Also allow machine-dependent
3306 processing to occur just before the main loop with
3307 BEFORE_MAIN_LOOP_HOOK.
3308 (main): If a "core file" argument is specified, and it is not a
3309 core file, try it as a process ID to attach.
3310 (symbol_completion_function): Attempt to cope with
3311 "show screen-" TAB, not very successfully. This needs more work,
3313 (batch_file): New function, returns whether we are reading
3314 commands from an interactive tty on stdin, or from somewhere else.
3315 Called by normal_stop since it doesn't get from_tty passed down
3316 to it like many commands do.
3318 * remote-nindy.c: Handle command line options for nindy
3320 (nindy_before_main_loop): Prompt user for tty name if they
3321 don't specify it before getting to the interactive command loop.
3323 * tm-i960.c: Add ADDITIONAL_OPTIONS, etc, to handle -O, -brk,
3324 and -r command line options. Also add hook before main loop
3325 to make it easy to specify a tty.
3327 * TODO: More things to do, one done.
3329 Mon Feb 4 23:57:39 1991 John Gilmore and Mike Tiemann (at cygint.cygnus.com)
3331 * dbxread.c: Make complaint() calls pass pointer, not struct.
3332 Add complaints about badly formatted C++ type information
3333 (const/volatile indicator, and parse errors resulting in
3334 error_type). Fix C++ virtual member fn comment.
3335 (read_struct_type): Avoid bumping pointer if we got a parse
3336 error; this prevents our walking beyond the end of a string.
3337 Terminate loop on null char as well as semicolon.
3338 (process_one_symbol): Fix the LBRAC fix so that it uses the
3339 last previous SLINE, FUN, or SO record's PC address. C++ debug
3340 symbols did not have SLINE records in a useful order compared
3341 to the LBRAC records.
3342 (define_symbol): Handle "catch" records.
3344 * symtab.c (check_stub_type): Added new complain
3345 `stub_noname_complain' and added a consistency check to
3346 keep the debugger from crashing when finishing from an
3347 exception frame. A real fix will be needed later.
3349 Sat Feb 2 10:43:05 1991 John Gilmore (gnu at cygint.cygnus.com)
3351 * infcmd.c (attach_command): Make global.
3353 * Makefile.dist (REMOTE_OBS): Make these compile by default,
3354 but make them easy to comment out. Perhaps later they should
3355 be enabled by what CPU you configure for? FIXME.
3356 (VERSION): Roll to 3.93.
3357 (pinsn.o): Remove rule for obsolete file.
3358 (dbxread.o,coffread.o,mipsread.o): Use ${srcdir} explicitly.
3360 Run down a problem that manifested by printing the wrong function
3361 name in stack traces of read_ofile_symtab. Turned out that the
3362 problem was the SunOS 4.1.1 (and previous) C compiler outputs
3363 the LBRAC symbol with an address in the *data* segment, which
3364 blew our binary search through the blocks.
3366 * dbxread.c: Use the complain() facility consistently to bitch
3367 about problems in the symbol file we are reading.
3368 (finish_block): Add code to check the nesting of the blocks;
3369 complain and Procrust them to fit if wrong.
3370 (make_blockvector): Check the order of the blocks, complain
3371 [but don't cope] if wrong.
3372 (process_one_symbol): ifndef SUN_FIXED_LBRAC_BUG, check LBRAC
3373 symbols to be sure their PC value is greater than the last SLINE
3374 (line number) symbol we've seen, complaining and adopting the
3375 SLINE PC value if wrong.
3377 * symfile.h (struct complaint, complaint_root, complain,
3378 clear_complaints): Add.
3379 * symfile.c (complain, complaint_root, clear_complaints): Add
3380 facility to deal with non-fatal complaints and to regularize their
3382 (symbol_file_add): Clear complaint counters to allow new complaints.
3383 (initialize_symfile): Add 'set complaints' and 'show complaints'.
3385 * dbxread.c (dbx_symfile_read): Remember the address and size
3386 of the string table for the main symbol file, so we won't read it
3388 (dbx_psymtab_to_symtab): Fix the check for main symbol file,
3389 to avoid reading the string table yet again. Lint.
3390 (throughout): Improve filtered output, including word wrap.
3391 (read_range_type): Improve Bothner's fix to handle other types too.
3393 * utils.c: Improve line wrap implementation. Handle unlimited
3394 width by making chars_per_line unsigned.
3395 (puts_filtered): New, easy, function.
3397 * defs.h (puts_filtered): add.
3399 * mipsread.c (compare_symbols, sort_symtab): Remove these fns,
3400 call the identical sort_symtab_syms() in symfile.c instead.
3402 * expread.y: Suggest the `file' command rather than `symbol-file'.
3404 * command.h (enum var_types): Add zinteger for seroable
3406 * command.c (do_setshow_command): Handle var_zinteger. Restructure
3407 nested if's into a switch.
3409 * breakpoint.c (bpstat_print): If bpstat "print" flag is not set,
3410 we did not stop because of a breakpoint (it must have been for
3411 some other reason, like a "stepi"), so don't print anything.
3413 * symtab.c: Include <sys/types.h> all the time. Now that BFD
3414 doesn't include <sys/types.h>, old SunOS's require it for
3417 Sat Feb 2 10:39:15 1991 Per Bothner (bothner@cs.wisc.edu)
3419 A test port of gdb-3.92.6 to the Sony NEWS.
3422 Don't normally link in remote- or vx stuff.
3423 Some of it doesn't compile, and it wastes space for 99% of the users.
3424 Remove reference to no-longer-used HAVE_VPRINTF.
3425 Fixed BFD_DEP typo to BFD_DIR.
3427 Fix cast in arg to bfd_h_getlong.
3428 Make char *prefix be const.
3429 Fix how certain range types are mapped into builtin unsigned int types.
3431 Remove 2 #includes. They cause errors (on Sony, at least),
3432 and aren't needed (they wern't in earlier versions).
3434 print_address_symbolic should never demangle labels
3435 (since it prints *assembler-level* labels).
3437 [This was superseded by the change to printcmd below.]
3440 Add some "volatile" return types to avoid warnings.
3441 If MISSING_VPRINTF add vprintf function and not just macro
3442 (since vprintf is used in printcmd.c).
3444 Unless __GNUC__, use obstack_grow instead of obstack_ptr_grow.
3445 (The latter isn't grokked by some PCC-based compilers.)
3447 [This change is in abeyance, we prefer to fix obstack_ptr_grow.]
3449 Make chunk size of dont_print_obstack 32*4 instead of default 4096.
3450 * nindy-share/coffstrip.c
3451 Added some forward declarations (otherwise, gcc complains
3452 about implicit extern redefined as static).
3454 Sun Jan 20 02:38:19 1991 John Gilmore (gnu at cygint.cygnus.com)
3456 Changes inspired by Per Bothner:
3457 * printcmd.c (print_address_symbolic): Take additional parameter
3458 specifying whether to demangle.
3459 (print_address): Pass in asm_demangle to control demangling.
3460 (print_address_demangle): New fn, takes explicit arg to control
3462 * utils.c: Add new vars demangle and asm_demangle, and let them
3464 (fputs_demangled): If !demangle, just print the argument.
3465 (fprint_symbol): If !demangle, just print raw symbol.
3466 * valprint.c (val_print): Call print_address_demangle rather than
3467 print_address, to cause demangling to depend on the global
3468 rather than assembler-level demangling setting.
3469 * WHATS.NEW, gdb.texinfo: Document.
3471 * main.c (show_command): Show all settings if no arg.
3472 (initialize_main): Make "info set" the same as naked "show".
3473 * command.c (cmd_show_list): Handle prefix commands in the
3474 list, and print the name of the setting as well as its English
3475 description and value.
3477 Allow gdb functions to specify where a line should wrap if it
3478 exceeds the size of a terminal line. Use it to make the output
3480 * utils.c (set_screen_width_command): New fn, mallocs a buffer
3481 of the right size when screen width changes.
3482 (set_screensize_command, screensize_info): Remove #if 0'd fns.
3483 (wrap_here): New fn, indicates a point in the output where we
3484 should wrap the line rather than just letting it overflow at a
3486 (fputs_filtered): Implement wrapping.
3487 (n_spaces): New fn, returns a pointer to N spaces.
3488 (print_spaces_filtered): Use n_spaces.
3489 * defs.h (n_spaces): Declare.
3490 * stack.c (print_frame_info): Wrap with 4-space indent after
3491 fn name and before filename and line number.
3492 * printcmd.c (print_frame_args): Wrap with 4-space indent
3493 before each argument name is printed.
3494 * valprint.c (value_print): Wrap with no indentation before
3496 (val_print_fields): Wrap with indentation relative to nesting
3497 level before each field name.
3498 (val_print): Wrap with nesting indentation before array elements.
3499 * command.c (do_setshow_command): Avoid extra newlines,
3500 wrap with 4-space indent around values printed, end with period.
3501 * WHATS.NEW, gdb.texinfo, gdb-int.texinfo: Document.
3503 * breakpoint.c (breakpoint_1): Implement addressprint for
3504 "info breakpoints" display. Change file name and line number
3505 format to " at file:nnn" rather than " (file line nnn)".
3506 * gdb.texinfo: Document.
3509 Fri Jan 18 07:21:25 1991 John Gilmore (gnu at cygint.cygnus.com)
3511 Frozen for gdb-3.92.6 release.
3513 README, WHATS.NEW: Update for 3.92.6 release.
3515 tconfig/{altos, i386v, i386v32, m88k, umax}: Eliminate
3516 coffread.o from configs since it is now built by default.
3517 tconfig/{3b1, altosgas, arm, convex, hp300bsd, hp300hpux,
3518 i386v-g, i386v32-g, isi, merlin, news, news1000, np1, pn,
3519 pyramid, symmetry, vax, vxworks68}: Eliminate dbxread.o
3520 from configs since it is now built by default.
3522 Makefile.dist: Update for release 3.92.6. Handle files that
3523 have been moved to ../include, ../getopt, or ../bfd. Add
3524 saber.suppress and tests directory. Add config.status to
3525 the release (it will say "none").
3527 coredep.c: Minor formatting fixes.
3529 These changes were made in early December but only checked in now:
3530 * nindy-share/Onindy.c, nindy-share/coffstrip.c,
3531 nindy-share/nindy.c: lint
3532 * nindy-share/nindy.c (ninStopWhy): Don't byteswap the
3533 register values coming back from the target; we store values
3534 in target byte order everywhere.
3536 Wed Jan 16 19:01:37 1991 John Gilmore (gnu at cygint.cygnus.com)
3538 * am29k-opcode.h, am29k-pinsn.c: Add 29050 opcodes.
3540 * valprint.c (cplus_val_print, val_print_fields): New functions,
3541 which print C++ objects. They conspire to avoid printing a
3542 virtual base class more than once, following all the twists and
3543 turns of C++ virtual base rules.
3544 (val_print): Call the above rather than do it by hand.
3546 * symfile.c (symbol_file_add): Only reset symfile_mtime for main
3547 symbol file, not for added files like shared libs. This really
3548 needs to be generalized to a timestamp per file.
3550 * core.c (cleanup_core): Avoid coredump if no core file.
3552 * config.gdb: Accept -host or -target in place of +host or
3555 * coffread.c (find_linenos): Avoid desupported BFD interface
3556 to line numbers. We still read them manually rather than using
3557 BFD's "generic" features.
3559 * gdbrc.tex, threecol.tex: Add GDB reference card and its
3561 Makefile.dist: Add refcard to OTHERS list for creating tar files.
3563 * Makefile.dist: Eliminate use of $< in explicit targets.
3565 * readline/Makefile: Use $< rather than $*.c, which does not
3566 include the VPATH in GNU Make.
3568 * tconfig/i960-bout, tconfig/i960-coff: These are identical
3569 copies of tconfig/i960, added for global configuration
3570 compatability. All i960 versions can read both coff and b.out.
3572 * tm-88k.h: Fix multiline macro that lacked \'s. Remove
3573 COFF_FORMAT and COFF_CHECK_X_ZEROES since these are now handled
3576 * TODO: Think of more things to do.
3578 Wed Jan 2 19:09:29 1991 John Gilmore (gnu at spiff.cygnus.com)
3580 tconfig/{am29k,i960,sun2*,sun3*,sun4*}: Eliminate config
3581 of sdb versus dbx debug symbols. Add kludge for 68881 80-bit to
3582 64-bit float conversion.
3584 tconfig/sun4, tconfig/sun3, xconfig/sun4, xconfig/sun3: Make
3585 equivalent to sun?os4 so global config works.
3587 Wed Jan 2 18:20:51 1991 John Gilmore (gnu at spiff.cygnus.com)
3589 Fix from Eberhard Mattes <mattes@azu.informatik.uni-stuttgart.de>
3591 * main.c: Only declare linesize once; declare pagesize not at
3592 all, since it is never used.
3593 (main): Clear newly allocated line before it is used.
3595 Fri Dec 28 00:13:42 1990 John Gilmore (gnu at cygint)
3597 Further stabilization for the Intel 960.
3599 * Makefile.dist: Parameterize the location of the "include"
3600 and "bfd" directories, as well as "getopt". Add symfile.c.
3601 Link in both dbxread and coffread. Fix up "make depend" to
3602 rewack the locations of include, bfd, and getopt in its output.
3604 * README: Document moving include files, improve some of
3607 * coffread.c: Move common code out to symfile.c. Change
3608 symbol_file_command style interface to use new *_symfile_init
3609 and *_symfile_read interface under BFD. Use BFD internal
3610 info to locate line table, symbols, etc.
3612 * core.c (core_fetch_registers): Rename to get_core_registers
3613 to avoid confusion with fetch_core_registers.
3614 (register_addr): Move to coredep.c, which is already machine
3615 dependent. This leaves core.c pretty clean of dependencies.
3617 * coredep.c (register_addr): Accept this routine from core.c.
3619 * dbxread.c: Move common code (with coffread.c, etc) into new
3620 symfile.c. Each psymtab now contains a pointer to the
3621 format-dependent function that knows how to read it in. Make
3623 (dbx_psymtab_to_symtab): Renamed from psymtab_to_symtab_2.
3624 (process_one_symbol): Add code to complain about a "compiler bug
3625 we muzzle here", if we actually see it.
3627 * eval.c (evaluate_subexp): Insert missing "break" statements
3628 in code that determines whether a variable is an lvalue in
3629 memory, register, or whatever. I detected this via a compiler
3630 bug in which it *almost* mashed out the whole switch statement.
3632 * gdb-int.texinfo: Add minor sections on configuring gdb for
3633 release, and about the README file.
3635 * infcmd.c (registers_info): Fix formatting somewhat. Still
3636 not as pretty as before, but it handles byte swapping.
3638 * remote-nindy.c: If data cache routines are interrupted while
3639 waiting for the remote end, be sure that any uninitialized cache
3640 blocks are on the free list, not on the valid list!
3642 * symfile.h: Flesh out this header file with all the various
3643 routines and variables that have been merged in from dbxread.c
3644 coffread.c, and symtab.c to symfile.c.
3646 * symfile.c: New file, containing code common to dbxread.c,
3647 coffread.c, and some code from symtab.c. All generic code for
3648 reading symbol files should be in here now.
3649 (unrecord_misc_function): Remove unused function.
3651 * symtab.h: Remove file-reading things to symfile.h.
3653 * symtab.c: Remove file-reading things to symfile.c.
3655 * tm-i960.h: Fix FRAME_CHAIN types; define PRINT_RANDOM_SIGNAL
3656 to decode i960 fault types.
3658 * target.h, remote.c, remote-eb.c, remote-vx.c, remote-nindy.c,
3659 target.c: Change type of the "resume" function from int to void,
3660 since its result was never used.
3662 Sat Dec 22 02:51:40 1990 John Gilmore (gnu at cygint)
3664 * main.c: Replace "stupid" with "caution"; you now "set caution
3667 * printcmd.c (print_scalar_formatted): Fix typo in 'g' format
3669 * infcmd.c (do_registers_info): Call val_print to deal with the
3670 byte order of the registers being printed. FIXME, this makes
3671 the formatting of the output uglier.
3673 * infcmd.c (wait_for_inferior): If PRINT_RANDOM_SIGNAL is
3674 defined, call it for signals the debugger doesn't itself use.
3675 The i960 uses this for more detailed fault information.
3677 * remote.c (remote_open): If arg is null, print help rather than
3680 * sparc-xdep.c (register_valid): Avoid declaring size, since
3681 various modules will think of various sizes depending on the
3682 architecture of their tm-file. FIXME, we need protection against
3683 actually entering one of those modules, which would clobber
3684 storage if not for the target architecture compiled into gdb.
3686 * stack.c (up_command, down_command): Always print the frame
3688 (up_silently_command, down_silently_command): New commands
3691 * i960-pinsn.c (reg), i960-tdep.c: Lint.
3693 * i960-tdep.c (i960_frame_chain_valid): Lookup_symbol now takes
3694 more parameters than it used to.
3696 * findvar.c (registers): Increase slop to 256 bytes, which should
3697 protect us against even most RISC machines with large register
3699 (locate_var_value): Move declaration inside related ifdef.
3701 * remote-nindy.c (): Use TIOCSETN rather than TIOCSETP
3702 throughout, to avoid throwing away buffered input from the board.
3703 (nindy_wait): Supply_register takes addr_of_value, not value.
3704 (i960_print_fault): Renamed from i80960_fault.
3705 (nindy_fetch_registers): Avoid have_regs stuff, just get them.
3706 (nindy_store_registers): Avoid regs_changed stuff, just stuff
3708 (nindy_create_inferior): Don't bother to write PC_REGNUM since
3709 we can set the PC in the call to proceed(). Unpush nindy_ops
3710 before pushing it on top, to avoid message to user. Eliminate
3711 commentary from Unix machines that just misleads here.
3712 (reset_command): Fix error message to suggest target command.
3714 Wed Dec 19 11:03:56 1990 John Gilmore (gnu at cygint)
3716 Release 3.92.5 as frozen.
3718 Stabilize the merged release...with help from lint, Saber C,
3721 Everywhere: Add include files needed to declare return types
3722 of functions called.
3724 * gdb.texinfo: Roland Pesch is documenting gdb, glory be!
3726 * breakpoint.h: Add undeclared breakpoint functions, and some
3727 functions for display handling since I couldn't think of a better
3730 * breakpoint.c (insert_breakpoints): Make code for disabling
3731 shared library bkpts more likely to work. It's used when we
3732 rerun a program and stop before the shared library has been
3734 (breakpoint_cond_eval, bpstat_stop_status): Pass arg as int,
3735 cast from pointer, so it squeezes through catch_errors.
3736 (bpstat_stop_status): Fix logic broken some time ago. We now
3737 always create a bpstat if the stop address matches a breakpoint,
3738 even if we don't stop there -- just like the old code used to do
3739 before I got my fingers into it (sigh).
3740 (breakpoint_1): Print "ignore count" after "stop only if"
3741 condition, since that's how it actually works.
3742 (mention): Handle watchpoints as well as breakpoints.
3743 (watch_command): use set_raw_breakpoint and mention to do most
3744 of the work (and initialize all the fields!). Only pass one
3745 arg to parse_c_expression, since that's all it takes.
3747 * command.c (not_just_help_class_command): Rename arg to args
3748 since we ignore "unused argument" warnings on vars named "args".
3749 inflow.c (child_terminal_info): ditto.
3750 infptrace.c (kill_inferior): ditto
3751 main.c (catch_errors, version_info, quit_command, pwd_command,
3752 source_command, dump_me_command, editing_info,
3753 set_history_size_command, set_history, show_history,
3755 stack.c (locals_info): ditto
3756 target.c (target_files_info): ditto
3757 valprint.c (set_input_radix, set_output_radix): ditto
3759 * core.c: Remove old variables for handling core and exec file
3760 sections (data_start, data_end, stack_start, stack_end,
3761 reg_stack_start, reg_stack_end, reg_stack_offset, text_start,
3762 text_end, exec_data_start, exec_data_end, text_offset,
3763 exec_data_offset, data_offset, stack_offset). They're
3764 superseded the more general build_section_table and
3766 (get_exec_file): Mention the `file' command.
3767 (read_memory_check): Rename to memory_error, and only call it
3768 in the case of an actual error.
3769 (read_memory, write_memory): call memory_error.
3770 (core_fetch_registers): Register section name is ".reg".
3772 coredep.c: Remove a bunch of crud now that all this file does
3773 is pull the registers out of a core file.
3774 (fetch_core_registers): Rewrite to actually work, I hope.
3776 dbxread.c: Use a.out.gnu.h, not system a.out, now.
3777 Replace index() with strchr(). Remove all the pre-BFD macro
3778 definitions for accessing the symbol file.
3779 (struct dbx_symfile_info): Encapsulate the information that
3780 dbx_symfile_init needs to pass to dbx_symfile_read in this
3783 (dbx_new_init, dbx_symfile_init, dbx_symfile_read,
3784 dbx_symfile_discard): Rearrange symbol file reading to divide
3785 the format-specific part from the format-independent part,
3786 leaving the format-independent part such as file name expansion
3787 and opening in symtab.c. This replaces
3788 partial_symbol_file_open and partial_symbol_file_read.
3789 Symbol_file_read, add_file, add_file_target_command,
3790 add_file_addr_command move to symtab.c. Pass an explicit
3791 "mainline" flag for when reading the main symbol table, rather
3792 than relying on the offset address to be zero or nonzero.
3794 (dbx_symfile_read): Don't allow void *'s to be printed as
3796 (SWAP_SYMBOL): Use bfd routines to byte-swap the symbols.
3797 (ADD_PSYMBOL_TO_LIST): Make the "function call rather than
3798 macro" debug version really work.
3799 (read_dbx_symtab): Remove unref'd parameter inclink.
3800 Avoid swapping N_SLINE symbols, for speed.
3801 Merge N_TEXT!N_EXT case with the other external symbol
3802 definitions' case. Add comments.
3803 (start_psymtab): Allocate the symfile name in the psymtab on
3804 the psymbol_obstack, rather than using the caller's storage.
3805 (end_psymtab): Only allocate a dependencies list if there are
3807 (psymtab_to_symtab_2): Use BFD when reopening file to read
3808 its symbols for real.
3809 (read_struct_type): Add FIXME comments where it needs work
3811 (read_huge_number): Add FIXME about overflows.
3812 (read_range_type): Add FIXME about comparing a long to 1<<32.
3814 * coffread.c: Minor changes to move things closer to the new
3815 regime with symtab.c and dbxread.c Major work is still needed
3818 * exec.c (exec_file_command): Remove old variables (see core.c
3820 (xfer_memory): If memory transfer is right at the end of a
3821 section, don't lose.
3823 * findvar.c (get_saved_register): If value is in a real
3824 register, LVAL is lval_register, not lval_memory.
3826 frame.h: Declare print_sel_frame and record_selected_frame.
3828 gdb-int.texinfo: New file, for GDB internals documentation.
3829 Very simple, unformatted doc of cleanups is there for now.
3831 gdbcore.h: Remove obsolete variables that described a.out
3832 section addresses and offsets. (See core.c above.)
3833 Declare fetch_core_registers and registers_fetched.
3835 getopt.c: Declare char *alloca(); even on SPARC.
3837 infcmd.c (run_command): Call target_kill rather than
3839 (step_command, next_command, stepi_command, nexti_command):
3840 Declare from_tty parameter even though we don't use it.
3841 (run_stack_dummy): argument BUFFER is a char array, not
3842 a pointer to REGISTER_TYPE.
3843 (finish_command): using_struct_return needed a value *,
3844 not a struct symbol *.
3846 * infptrace.c (child_xfer_memory): To avoid dependency on
3847 where sections are in memory, try PT_WRITE_D and if that fails,
3848 try PT_WRITE_I. Most Unixes don't care which you use.
3850 * infrun.c (step_resume_break_shadow): Change to array to
3851 match other breakpoint shadow storage.
3852 (clear_proceed_status): Pass address of bpstat to
3853 bpstat_clear, not the bpstat itself.
3854 (child_create_inferior): FIXME comment about if the child
3856 (start_inferior): Remove old function.
3857 (child_open): Use target_kill rather than kill_inferior.
3858 (wait_for_inferior): Ditto.
3859 (insert_step_breakpoint, remote_step_breakpoint): Use
3860 new step_resume_break_shadow.
3862 * inftarg.c (child_wait): If all child processes die,
3863 pretend that the one being waited for exited with signal 42.
3865 * main.c (command_line_input): When scanning for comments,
3866 don't coredump on unclosed quotes.
3867 (quit_command): Use target_kill rther than kill_inferior.
3868 (_initialize_main): Rename class_user from "user" to
3871 * printcmd.c (print_command_1): Initialize "fmt" if no format
3872 is specified by the user.
3873 (print_frame_args): Only add to args_printed if we are
3874 actually fetching args from the stack (avoiding undefined
3876 (_initialize_printcmd): Remove bogus \{ from string.
3878 * remote-eb.c (eb_open): Avoid coredump on no argument.
3880 * remote-nindy.c: Bring out of Intel environment into new
3881 target environment. Remove all conditional compilation on
3882 I80960. Massive hacking throughout.
3883 (nindy_xfer_inferior_memory): New routine stolen from
3885 (nindy_create_inferior): New routine pieced together, probably
3886 not quite working yet.
3887 (nindy_ops): New target_ops struct for nindy.
3889 * remote-vx.c: Use write_memory rather than target_write_memory
3890 to get error checking.
3891 (vx_add_file_command, vx_open): Use symbol_file_add rather than
3893 (vx_create_inferior): Use target_terminal_ours...
3895 * signame.c (_initialize_signame): Always initialize, since
3896 we need the table for things other than psignal.
3898 * solib.c (solib_add): Use symbol_file_add, not add_file.
3899 (solib_address): Return boolean result rather than struct
3900 pointer which nobody else knows the type of.
3902 * sparc-tdep.c, valops.c: Use write_memory rather than
3903 target_write_memory, to get error checking.
3905 * stack.c (locals_info, catch_info, args_info,
3906 get_selected_block, frame_command, up_command): Use
3907 target_has_stack, rather than have_inferior_p or
3910 * sun3-xdep.c (fetch_core_registers): Rewrite for new BFD regime.
3912 * symfile.h: New file, defining the interface between the
3913 generic and object-file-specific symbol reading code.
3915 * symtab.c: Move generic symbol-reading interface to symtab.c,
3916 from dbxread.c, coffread.c, mipsread.c, etc. Add symtab_fns
3917 table to map BFD targets to symbol-reading modules in GDB.
3918 Change index to strchr.
3919 (lookup_struct_elt_type): Use error() rather than hand-made
3920 simulations thereof.
3921 (lookup_partial_symbol): Speedup slightly when length == 0.
3922 (symbol_file_add): New function.
3923 (symbol_file_command): Call it.
3924 (symfile_open, symfile_init): New function.
3925 (add_file_target_command, add_file_addr_command): moved from
3928 * target.c (target_command): use target_kill.
3930 * target.h (target_files_info): Don't declare, never called
3933 * tm-sun2.h, tm-sun3.h (STACK_END_ADDR): Use system include
3934 files to determine stack end address.
3936 * valarith.c (value_x_binop, value_x_unop): Change error message
3937 to be more useful. Pass proper argument to value_struct_elt.
3939 * valops.c (value_assign): FIXME comment that long long
3940 bitfields will break here.
3942 * Makefile.dist: Add symfile.h, remote-nindy.c, remote-eb.c.
3943 Update `make saber_gdb' to work better.
3945 * TODO: A woman's work is never done.
3947 * cplus-dem.c, environ.c, inferior.h, infrun.c, inftarg.c,
3948 main.c, obstack.c, printcmd.c, remote-eb.c, remote-nindy.c,
3949 remote-vx.c, remote.c, solib.c, source.c, sparc-pinsn.c,
3950 sparc-tdep.c, sparc-xdep.c, symmisc.c, symtab.c, symtab.h
3951 target.c, terminal.h, tm-sparc.h, tm-sunos.h, utils.c,
3952 valops.c, valprint.c, exec.c: Lint.
3955 Wed Dec 12 23:44:15 1990 John Gilmore (gnu at cygnus.com)
3957 Continuing Intel 960 port merge of GDB.
3959 * Makefile.dist: Merge i960 "nindy-share" files. Rename
3960 malloc.h to gmalloc.h to avoid name conflicts in /usr/include.
3961 Don't ship gdb.dvi in tar file. Link gdb with init.o, not init.c.
3962 Wack over "make depend" so it handles files in subdirectories
3963 vx-share, nindy-share, bfd, and in the current directory.
3965 * blockframe.c (get_prev_frame_info): Remove fatal error
3966 if stack not defined.
3968 * core.c (core_open, core_detach): New functions that handle
3969 the old "core-file" command as "target core" and "detach" instead.
3970 (core_file_command): Call them.
3971 (core_xfer_memory): Use common routine xfer_memory.
3973 * dbxread.c: Include a.out.gnu.h, not system a.out.h.
3974 dbxread now uses bfd for everything but symbol reading itself.
3975 BFD internals are used to drag out the relevant file offsets.
3976 (partial_symbol_file_open): Change args all around for BFD.
3978 * symtab.c: Rename "value" to "val" everywhere, so we can
3980 (symbol_file_command): New command, moved from dbxread.c
3981 and coffread.c. It uses BFD to read the file, then vectors
3982 based on its type, to dbx or coff symbol readers.
3983 * symtab.h: Extern a few vars for symbol_file_command.
3985 * target.h: Breakpoint takes a char * save area, not a char **.
3987 * valprint.c (val_print): When unpacking bitfields, offset
3988 the address in gdb of the value, if it is declared with a shorter
3989 type. Remove the last "runtime kludge test" of host byte order.
3991 * utils.c: Remove old my_bfd_read routine.
3993 * stack.c (frame_info): Use target_has_stack. Print program counter
3994 register's actual name rather than "pc", since it's called the
3995 "ip" (instruction pointer) on the i960 (sigh).
3997 * target.c (target_command): Add command for selecting a target
3998 type and calling its open routine. This is used for initiating
3999 communication with a particular target, in a generic way.
4001 * tm-i960.h: Update for modern gdb. Remove semicolons from
4002 various macros. Handle reading struct return convention, and
4003 error-out attempts to return structs with the "return" command.
4004 Be sure gdb doesn't think we know how to call functions in the
4007 * i960-tdep.c: Rename FRAME_CHAIN_VALID and FRAME_FIND_SAVED_REGS
4008 to i960_xxx in lower case.
4009 (arg_address): Circumvent errors due to LOC_ARG_BLOCK
4010 not being defined yet.
4012 * remote.c (remote_open): Call start_remote to initialize
4013 wait_for_inferior during open.
4014 (remote_xfer_inferior_memory): Return length written rather
4017 * remote-vx.c (target_command -> vx_open): Use new generic
4019 * remote-eb.c, inftarg.c, exec.c: ditto.
4021 * infrun.c: Fix comments.
4022 (attach_program -> child_open): Use new generic target command.
4023 (wait_for_inferior): Clear saved register values before target_wait,
4024 so target_wait can set some of them if convenient.
4026 * infptrace.c (fetch_inferior_registers, store_inferior_registers):
4027 Return success indicator, not void.
4028 (child_xfer_memory): Avoid fetching initial word if we'll
4029 overwrite it anyway.
4031 * infcmd.c (attach_command): Use new generic target open routine.
4032 (_initialize_infcmd): Update doc on attach and detach commands.
4033 (do_registers_info): Merge in a byte-order problem as a FIXME
4036 * findvar.c (find_saved_register): Avoid problem in current frame.
4037 (read_relative_register): Ditto.
4038 (write_register): Convert byte order on the way out.
4040 * exec.c (file_command): Add.
4041 (add_to_section_table, exec_command): Use new bfd_map_over_sections.
4042 (xfer_memory): Common function between core_xfer_memory and
4044 (exec_xfer_memory): Use it.
4046 * pn-opcode.h: Document that a "PN" is a Gould PowerNode.
4048 * breakpoint.c, breakpoint.h, symtab.h, value.h, frame.h, utils.c,
4049 valops.c, stack.c, target.c, sparc-xdep.c, source.c, printcmd.c,
4050 infcmd.c, i960-pinsn.c, eval.c, defs.h: lint and gcc -Wall.
4052 Sun Dec 2 16:45:06 1990 John Gilmore (gnu at cygnus.com)
4054 Merge Intel 960 port of gdb, continuing...
4056 * dbxread.c (partial_symbol_file_open, partial_symbol_file_read,
4057 symbol_file_command): Pass from_tty arg to hush 'em up.
4059 * coffread.c (symbol_file_command): Avoid output if from_tty != 1.
4060 Add magic numbers for 960 COFF format.
4062 Fri Nov 30 09:18:20 1990 John Gilmore (gnu at cygnus.com)
4064 Merge Intel 960 port of gdb, from Intel "1.2" release.
4066 CHANGE_LOG entries from their port, which was based on
4069 Thu Sep 6 11:02:22 PDT 1990
4070 Remove temp file if download is interrupted.
4072 Wed Aug 1 09:08:33 PDT 1990
4073 Now uses binary protocol to talk to NINDY.
4074 Old hex protocol (NINDY 2.13 and older) supported with -O switch.
4075 Times out after 5 seconds when trying to talk to NINDY.
4077 Tue May 29 12:54:49 PDT 1990
4078 Added variable baud rate (-b switch).
4079 Source code reorganization.
4081 Thu Apr 26 11:09:55 PDT 1990
4082 More cleanup of batch mode; specifically, execute "-s", "-e", and
4083 "-se" switches as soon as they are encountered on the invocation line.
4085 Fri Apr 20 13:47:15 PDT 1990
4088 Thu Apr 19 09:54:28 PDT 1990
4089 Add 'reset' command.
4091 Wed Apr 18 09:48:07 PDT 1990
4092 After opening remote tty, wait for 1 second to go by without input
4093 from it before trying to talk to NINDY (fixes problems with the
4094 Heurikon HK80/V960E).
4096 Mon Apr 4 16:33:05 PDT 1990
4097 Some output was not being suppressed in 'batch' mode.
4099 Thu Mar 22 15:31:11 PST 1990
4100 Ask user if old symbol table should be deleted when new file is
4103 Allow user to run a program downloaded before gdb960 was brought up.
4105 Correct "exec-file" help message for i80960 context.
4107 Correct bug in calculating user space address: could occasionally
4108 corrupt user program.
4110 Make sure to zero low-order bits in rip's because of bug in 960CA
4111 A-step part: could cause operation faults when "next"ing across
4114 Correct bug that made it impossible to get source line numbers for
4115 code loaded at addresses higher than 0x7fffffff.
4117 Wed Jan 10 12:43:22 PST 1990
4118 Open remote tty for exclusive use.
4120 Fri Jan 5 12:14:42 PST 1990
4121 Correct disassembly (CA manual was right after all):
4122 opcode for sysctl is 0x659
4124 Mon Oct 23 12:03:04 PDT 1989
4125 Use G960BASE and G960BIN environment variables to find 'sx' utility.
4127 Mon Oct 16 14:15:09 PDT 1989
4128 "sfr0"-"sfr31" should have been named "sf0"-"sf31"
4130 Mon Oct 2 15:56:31 PDT 1989
4132 Added 960CA disassembly support.
4134 To simplify maintenance:
4135 - eliminated use of symblic links on pinsn.c: use i960-pinsn.c
4137 - eliminated opcode.h: incorporates tables into i960-pinsn.c
4138 - moved 960-specific routines from i960-pinsn.c to i960-md.c
4139 - made disassembly interface identical to that in gdmp960.
4143 Wed Nov 28 21:32:48 1990 John Gilmore (gnu at cygint)
4145 * target.h: Allow targets to stack. Add target_has_memory,
4146 _registers, etc. Restructure memory access and "info files"
4147 to walk the target stack.
4148 * exec.c, core.c, inftarg.c, remote.c, remote-vx.c, remote-eb.c,
4149 target.c: Change tables to match target.h.
4150 * inflow.c (child_mourn_inferior): pop child_ops.
4151 (generic_mourn_inferior): Use new has_stack flag.
4152 * infptrace.c (child_xfer_memory): New memory regime.
4153 * inftarg.c (child_files_info): New "info files" regime.
4154 * remote-eb.c: New memory regime, new info files.
4155 * remote-vx.c: New memory regime, new info files. Now use
4156 separate targets for VxWorks attachment to machine, and
4157 actually running a process under VxWorks, since one has
4158 stack & execution & regs and the other doesn't.
4159 * remote.c: New memory regime, new info files.
4160 * sparc-xdep.c (fetch_core-registers): New memory regime.
4161 * target.c: New routines and support for stacked targets,
4162 new memory regime, new info files regime.
4165 Generalize section handling for an arbitrary number of sections,
4166 including use of the new BFD (binary file) library.
4167 * gdbcore.h: Add struct section_table.
4168 * exec.c (build_section_table): Iterate all sections and
4169 record what gdb needs to know about them.
4170 (exec_command): Use it.
4171 (exec_xfer_memory): Use the table.
4172 (exec_files_info): Print the table.
4173 * core.c (core_file_command, core_xfer_memory, core_files_info):
4175 * source.c (find_source_lines): Use bfd_get_mtime.
4176 * dbxread.c: Quick changes to make it compile with new BFD.
4177 * utils.c (error): Avoid using bfd_error in generic routines.
4179 * core.c (core_fetch_registers): Get from the ".regs" section of
4181 * sparc-xdep.c (fetch_core_registers): Use the .regs info.
4183 * inferior.h (attach_flag): Export.
4184 * infcmd.c (run_command): use new target_create_inferior.
4185 * infrun.c (child_create_inferior): Don't return result.
4186 * Makefile.dist (VERSION): 3.91.4.
4188 Fri Nov 23 28:15:38 1990 John Gilmore (gnu at cygint)
4190 * breakpoint.c (bpstat_num): Handle breakpoints which have
4191 since been deleted, such as temporary breakpoints.
4192 infcmd.c (program_info): ditto.
4194 * core.c (core_file_command): Display the frame where the core
4199 * remote-vx.c (target_command): Merge in target command from
4200 targ-vx.c. A few other cleanups.
4202 * TODO, Projects: Lots more stuff to do...
4204 Fri Nov 23 18:15:38 1990 John Gilmore (gnu at cygint)
4206 Massive changes to wall off the remote-debugging interface
4207 behind a function vector. The port to handle VxWorks targets
4208 is also part of this.
4210 All files: Replace references to renamed functions,
4211 remove references to remote_debugging, remove references to
4212 have_include_file, have_core_file in favor of target_has_stack,
4213 target_has_memory, etc.
4215 * Modularize the breakpoint interface.
4216 breakpoint.h (BREAKPOINT_MAX): New define sets max length of
4217 a breakpoint instruction.
4218 breakpoint.c: struct breakpoint's shadow_contents now sized as
4220 (insert_breakpoints): Vector to target to install breakpoints.
4221 (remove_breakpoints): Vector to target here too.
4222 Remove REMOTE_SA_SPARC kludges and other remote_debugging.
4223 sparc-tdep.c (single_step): Use new breakpoint interface for
4224 the single-step breakpoints.
4225 mem-break.c (memory_insert_breakpoint, memory_remove_breakpoint):
4226 New file, contains routines to insert and remove breakpoints by
4227 reading out the old contents and later replacing them. This is
4228 how ptrace breakpoints work, and many remote systems as well.
4230 * tm-vxworks68.h: New config file, overrides a few things for
4231 Wind River's preferences.
4233 * target.h: New file, for transfer vector used to talk to the
4234 inferior (child, attached, core, exec, remote, etc). All accesses
4235 to the thing being debugged should come through these vectors.
4236 target.c: New file, routines to handle transfer vector.
4237 (various files): Add transfer vectors XXX_ops for the various
4238 targets and pseudo-targets (core files, etc) we support.
4240 * breakpoint.c (bpstat_stop_status): Further explorations of
4241 watchpoints and why things don't work all the time.
4242 (bpstat_alloc): New fn to allocate a bpstat and chain it.
4244 * config.gdb: Only add "source ${srcdir}/.gdbinit" to
4245 the local gdbinit if it doesn't already have it.
4247 * core.c (core_ops): add and install.
4248 Allow core debugging without exec file.
4250 * dbxread.c (free_and_init_header_files): Merge two fns.
4251 (end_symtab): Free named symbol table when a new version comes in.
4252 (read_dbx_symtab): Relocate all kinds of symbols with base
4253 address. First step toward handling different text, data, bss
4255 (add_file_addr_command): Renamed add_file_command.
4256 (add_file_command): Vector to remote handler.
4257 Add "load" as an alias for "add-file" command.
4259 * defs.h: Allow "volatile" to be used in non-ANSI; use it for
4260 non-returning functions.
4262 * exec.c: Add exec_ops, and push it as a target when an exec
4265 * infcmd.c (run_command): Pass executable file name and arg list
4266 separately when starting an inferior. Permit "run" when no exec
4267 file is specified, for VxWorks.
4268 (detach_command): Move to child_detach in inftarg.c.
4270 * inftarg.c: New file. Unix-child-specific routines, and the
4271 child_ops structure.
4273 * inferior.h (registers): Export "registers" as the way for
4274 target dependent register handlers to find gdb's local copy of
4275 the registers. Rename "stop_after_attach" to "stop_soon_quietly"
4276 since it is now used by places that want wait_for_inferior to
4277 handle the grunge but want to see every trap from the inferior.
4279 * inflow.c (create_inferior): Pull out, and merge into infrun.c.
4280 Eliminate remote_debugging hooks in terminal handling.
4282 * infrun.c: Replace start_inferior with child_create_inferior.
4283 Move all the hair of Unix shells and ptrace idiosyncracies into
4284 child_create_inferior, so remote handlers don't have to deal.
4285 Remove running_in_shell. Rename stop_after_attach to
4286 stop_soon_quietly, and use it in a few other places where we want
4287 to just call wait_for_inferior and get control back on the first
4288 trap. trap_expected now never takes a value > 1.
4289 (init_wait_for_inferior): Initialize static vars when a new
4292 main.c (gdbinit): Add new hook for .gdbinit file name, let
4293 it be overridden by config files as GDBINIT_FILENAME.
4294 (DEFAULT_PROMPT): Add new hook for overriding (gdb) prompt.
4295 Both of these are used for VxWorks gdb.
4297 mcheck.c: rename include file "gmalloc.c" to avoid problems
4298 with system include file "malloc.c".
4300 param-no-tm.h: New include file, same as param.h but does not
4301 include the default "tm.h" file. This is used in files where
4302 the target is known, e.g. remote-eb.c or sparc-xdep.c.
4304 param.h: Now just a shell that includes tm.h and param-no-tm.h.
4306 remote-vx.c: New file, VxWorks remote debugging support. Uses
4307 RPC routines that are shared with the target system, in directory
4310 remote.c: Vectorize remote interface.
4312 source.c: Globalize source_path, and make an alias "l" for "list"
4313 since we now have the "load" command.
4315 sparc-xdep.c: Use new param-no-tm.h.
4317 symmisc.c (free_named_symtab): Add new function from Wind River.
4318 However, ifdef it out for now while we think about what it should
4321 tm-sun3.h, xm-sparc.h, xm-sun3.h, xm-symmetry.h: Move
4323 the xm- file, and change its name to CHILD_PREPARE_TO_STORE, since
4324 non-Unix-children handle this with their own code in the target
4327 Makefile.dist: Roll version to 3.92.3. Add vx-share stuff to
4328 source and target lists. Add vx-share to default list of include
4329 directories. Add new files to src and target lists: mem-break,
4330 target, inftarg, remote-eb, remote-vx, targ-vx. Be sure the
4331 ${srcdir} versions of munch and createtags are used.
4333 * valops.c (find_function_addr): Split out of call_function.
4334 (call_function_by_hand): Rename call_function; this function
4335 calls functions in the target by laboriously patching the target
4336 word-by-word with the right stack, args, regs, etc.
4339 Mon Nov 5 17:29:10 1990 John Gilmore (gnu at cygint)
4341 Handle AMD 29000 a bit better.
4343 * remote-eb.c (readchar): Mask received char log to make it readable.
4344 (remote_start): Pass arguments down to executing program.
4345 Make startaddr unsigned.
4346 infrun.c (start_inferior): Accept args, pass them to
4348 infcmd.c (run_command): Pass args down to start_inferior.
4350 * tconfig/am29k-aout, tconfig/am29k-coff: New files specifying
4351 the target object file format.
4352 tm-29k.h: Pay heed to COFF_ENCAPSULATE.
4354 * am29k-pinsn.c (print_insn): Print 0x on hex numbers in disassembly.
4355 am29k-tdep.c (examine_prologue): Better checking of function prefixes.
4357 Sun Oct 7 18:20:45 1990 John Gilmore (gnu at cygint)
4359 * Makefile.dist (VERSION): Roll version to 3.91.9 and freeze.
4360 * TODO: We did a few things, we have more to do though.
4362 * xm-sparc.h (CLEAR_DEFERRED_STORES): Define.
4363 * inflow.c (inferior_died): Clear deferred stores.
4365 * Debug problems with dummy frames and calls to the inferior.
4366 * tm-sparc.h (PUSH_DUMMY_FRAME, POP_FRAME): Move to sparc-tdep.c.
4367 * sparc-tdep.c (do_restore_insn): Simplify.
4368 (sparc_frame_find_saved_regs): Simplify and fix what we find.
4369 (sparc_push_dummy_frame): Simplify and fix what we push.
4370 (sparc_pop_frame): Slightly more hair here, deciding whether
4371 we are restoring a saved PC or returning to a return address in %i7.
4372 * sparc-xdep.c (read_inferior_registers): Debug if valid reg is read.
4374 * utils.c (xmalloc, xrealloc): Return type depends on __STDC__.
4375 * symtab.h (xmalloc): ditto, for obstack_chunk_alloc.
4376 * obstack.h (chunkfun): ditto.
4377 * defs.h (xmalloc, xrealloc): ditto
4379 * utils.c (quit): Grab the terminal from the child if necessary.
4381 * inflow.c (term_status_command): Rename to term_info, change
4384 * sparc-pinsn.c (print_insn): Disassembly prefers real instructions.
4385 (is_delayed_branch): Speed up.
4386 * sparc-opcode.h: Add ALIAS bit to aliases. Fix up opcode tables.
4387 Still missing some float ops, and needs testing.
4389 * Support for input and output radixes other than base 10
4390 * defs.h (input_radix, output_radix): Declare.
4391 * expread.y (yyparse, parse_number): Handle changes of input
4392 radix, and ambiguous names-or-numbers in radixes >10.
4393 * printcmd.c (print_scalar_formatted): Print formatted hex
4394 numbers in varying column widths.
4395 * valprint.c (val_print): Use output_format to print scalar ints.
4396 (set_input_radix, set_output_radix, set_radix): Create.
4397 (set_output_radix): Set output_format from output_radix.
4398 (_initialize_valprint): add `set radix' but leave the others off.
4400 * main.c (execute_command): Let stupid questions be turned off.
4401 (_initialize_main): Handle "set stupidity", etc.
4403 * main.c, inflow.c, inferior.h, frame.h, command.c, defs.h,
4404 sparc-pinsn.c, sparc-xdep.c, value.h, valops.c, values.c: Lint.
4406 Tue Oct 2 11:20:02 1990 John Gilmore (gnu at cygint)
4408 * TODO, Makefile.dist, ChangeLog: Freeze for 3.91.8 release.
4409 bfd stuff is still screwed up, but with some manual work, it
4412 * breakpoint.c (bpstat_do_actions): Start over if a command
4413 proceeds the inferior, since the inferior will have stopped and
4414 will need to have its new stop-actions taken care of.
4416 * dbxread.c (read_struct_type): Expression gives Sun3 4.0.3
4417 compiler fits, simplify it.
4419 * gdb.texinfo (directory command): Doc new dir command.
4420 source.c (directory_command): "dir" now puts things on the front
4421 of the path, moves dups up front, and handles multiple names
4422 on the command line, inserting each one in order. It also
4423 blows away cached line and full_filename info.
4425 * stack.c (backtrace_command): Skip "more stack frames follow"
4428 * Change #ifndef HAVE_VPRINTF to #define MISSING_VPRINTF in
4429 xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
4430 xm-np1.h, xm-pn.h, xm-pyr.h, xm-symmetry.h, xm-umax.h, xm-vax.h.
4431 The only odd one was Gould NP1, which had defined vprintf to
4434 * Merge Ted Goldstein <tedg@Eng.sun.com>'s changes for epoch.
4435 printcmd.c (print_command_1): Pass 'inspect' flag down as a global
4436 variable, inspect_it.
4437 valprint.c (print_string, val_print): Use the global inspect_it
4438 to indicate whether to print in Epoch style or normal style.
4440 Mon Oct 1 23:55:26 1990 John Gilmore (gnu at cygint)
4442 * printcmd.c (call_command): add an alias for the "print" command
4443 which runs expressions and doesn't print the result if void.
4444 (print_command_1): implement it.
4446 * command.c: Remove #if 0'd code. Initialize all the fields
4447 in add_cmd (). Rename do_nothing_command to
4448 not_just_help_class_command, and make it externally visible.
4449 command.h: add user_commands to struct.
4450 * main.c (define_command): Don't overload c->function with a char
4451 string as well as a function pointer.
4453 * eval.c (evaluate_subexp): Reinstall tiemann changes to
4454 calling convention of value_struct_elt () that got dropped in
4457 * tm-sparc.h (FRAME_FIND_SAVED_REGS): move to sparc-xdep.c.
4458 sparc-tdep.c (sparc_frame_find_saved_regs): ditto.
4460 * tm-sparc.h (POP_FRAME): replace some constants with defines.
4462 * sparc-xdep.c (store_inferior_registers): defer stores to regs
4463 until a good time (e.g. when we are about to run the child),
4464 saving ptrace calls.
4465 * infrun.c (proceed): handle DO_DEFERRED_STORES.
4466 * tm-sparc.h: define DO_DEFERRED_STORES.
4468 * sparc-xdep.c (store_inferior_registers): when storing float
4469 registers, don't store stack regs too. When storing the SP,
4470 however, DO store the stack regs too. This fixes a bug in which
4471 the dummy frame is not recognized when a call_function finishes,
4472 because its frame pointer (in the stack regs) was never
4474 (read_inferior_registers): Mark WIM and TBR and FPS and CPS valid
4475 even though we don't know how to read them from an inferior.
4476 valops.c (call_function): Comment about storing SP.
4478 * infrun.c (save_inferior_status): Save away the original bpstat
4479 chain so it can be restored later. Install the copied version for
4480 use by whoever saved the status. It will be blow away by
4481 restore_inferior_status, and the original chain restored. This is
4482 important for people who have pointers into the original.
4484 * breakpoint.c, command.h, copying.awk, dbxread.c, defs.h,
4485 findvar.c, frame.h, obstack.h, obstack.c, inflow.c, value.h,
4486 main.c, printcmd.c, sparc-tdep.c, symtab.c, valprint.c: lint
4489 Fri Sep 28 20:32:46 1990 John Gilmore (gnu at cygnus.com)
4491 * Makefile.dist: Roll version to 3.91.8. Add bfd.h and bfdconfig.h
4492 temporarily to the makefile. Add am29k-opcode.h and WHATS.NEW.
4493 Add stuff.c and kdb-start.c to the OTHERS list for tar files.
4495 Fri Sep 28 19:12:12 1990 John Gilmore (gnu at cygint)
4497 * Merge Mike Tiemann's multiple inheritance changes from Sun.
4498 Store the baseclasses in a type struct starting from array element
4499 0 rather than from the unusual array element 1.
4501 dbxread.c: the above.
4502 (virtual_context): Add
4503 Read new debug information about which virtual function table
4504 a virtual function is from, and store it in fn_field.fcontext.
4506 symtab.h: Add fcontextt. Fix baseclass indices. Typo in
4507 TYPE_FN_FIELD_STATIC_P.
4509 symtab.c: the above.
4510 valops.c: the above. Handle pointer casts of object *'s.
4511 (search_struct_method): Add.
4512 (value_struct_elt): First arg is now a pointer to a value, and is
4515 valprint.c: the above.
4516 values.c (value_virtual_fn_field): Add type arg. Handle
4517 offsetting to the proper object when calling virtual fns.
4519 (baseclass_addr): Add valuep arg.
4521 * README: Document the current state of BFD config (missing).
4522 * TODO, ChangeLog, Makefile.dist: Roll version.
4523 * WHATS.NEW: Add summary of changes since 3.5.
4525 Thu Sep 27 16:23:12 1990 John Gilmore (gnu at cygint)
4527 * dbxread.c (read_struct_type): Clear bit vectors whenever
4529 symtab.c (B_CLRALL): define.
4531 * tm-sparc.h (STORE_RETURN_VALUE): Avoid clobbering types by
4532 using == rather than =. Huh... This fixes the dreaded problem
4533 wherein builtin_type_int becomes TYPE_CODE_FLT.
4535 * core.c (info_files): Show the inferior pid.
4537 * config.gdb: Avoid putting "dir" command into .gdbinit. GDB
4538 already knows how to look in the source directory.
4540 * Remove psymtab hair from many places. Remove duplicated code
4541 for searching symbol tables. Hide psymtabs from most places.
4542 Make it fast to get from a psymtab to its symtab.
4544 blockframe.c (blockvector_for_pc): Remove psymtab hair.
4545 coffread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4546 mipsread.c (psymtab_to_symtab): Rename to psymtab_to_symtab2.
4547 dbxread.c: export psymtab_to_symtab, make it work if called N times.
4548 (psymtab_to_symtab): Rename to psymtab_to_symtab2. Initialize
4549 new symtab completely. New psymtabs get symtab pointer
4550 initialized to zero. Remove MI warning printf.
4551 symtab.h: Comments. Add psymtab to symtab pointer.
4552 (PSYMTAB_TO_SYMTAB): New macro.
4553 symtab.c: use PSYMTAB_TO_SYMTAB. Add psymtab_to_symtab and export it.
4554 source.c: use PSYMTAB_TO_SYMTAB. Remove symtab version and
4556 stack.c (backtrace_command): Avoid pre-pass to read symbols, if
4558 (print_frame_info): Avoid special-casing symbols that have not yet
4561 * source.c (open_source_file): Quick path if we have already
4562 located the source file by its full name.
4564 * symtab.c (lookup_symbol): Use find_pc_symtab rather than
4565 find_pc_psymtab. When a name is found in the misc function
4566 vector, search the symbol table for its mangled name, not the
4567 name that the user typed.
4569 * bfd.h: Fix missing comment terminators, make #endifs match.
4571 * valarith.c (value_less): Handle unsigned int comparisons.
4572 Add FIXME about pointer compares, which assume host and target
4573 pointers are the same.
4575 * command.c (do_nothing_command): lint
4576 dbxread.c: lint. Remove sort_syms. Document C++ visibility info,
4577 fix comments on debug symbol format for visibility. Actually set
4578 visibility of symbols.
4579 main.c (echo_command): lint; use <readline/history.h>.
4580 tm-sparc.h (FRAME_FIND_SAVED_REGS): lint
4581 obstack.h (_obstack_blank): Rearrange pointer math to avoid
4582 pointing past end of allocated memory; saber complains.
4583 obstack.h: Declare the external functions that we use.
4584 valarith.h: use <string.h>
4585 solib.c (solib_add): lint.
4587 Fri Sep 21 17:05:19 1990 John Gilmore (gnu at cygint)
4589 * main.c (initialize_main): Default info_verbose to off, now that
4590 symbol reading is fast.
4591 (quit_command): Avoid clobbering exec_bfd while quitting.
4593 * Initial BFD (binary file diddling library) merger:
4594 coffread.c: Change AOUTHDR to struct exe_hdr.
4596 core.c: initialize initialized data at compile time.
4597 (core_file_command): Move from coredep.c, convert to bfd.
4598 (xfer_core_file): Convert to bfd.
4599 exec.c (exec_file_command): use bfd routines.
4601 mips-tdep.c: Remove exec_file_command and friends.
4604 * coredep.c: (fetch_core_registers) Convert core_file_command to
4605 fetch_core_registers.
4606 mips-xdep.c, sparc-xdep.c, sun3-xdep.c: ditto.
4608 * utils.c: (error): Bogus crap, FIXME, to print bfd errors.
4609 (my_bfd_read): More bogosity, which I don't think we call.
4610 (program_name): Remove this atrocity asap!
4612 Wed Sep 19 13:36:41 1990 John Gilmore (gnu at cygint)
4615 values.c: allocate_repeat_value was not clearing the
4616 optimized_out field.
4617 (value_static_field): minor stylistic fix (wrong macro was used).
4618 valops.c (value_struct_elt_for_address): didn't work for C++
4621 * signame.c (_initialize_signame): Initialize signal names once.
4623 * breakpoint.h, command.c, copying.awk, defs.h, environ.c,
4624 exec.c, frame.h, infcmd.c, inferior.h, main.c, munch, sun3-xdep.c,
4625 symtab.h, tm-29k.h, valprint.c, value.h, values.c: Lint.
4627 * remote-eb.c: Support user-settable baud rates on the serial port.
4629 * tm-sun3.h (PREPARE_TO_STORE): fix typo.
4631 Fri Sep 14 13:28:29 1990 John Gilmore (gnu at cygint)
4633 * tconfig/sun3os4: Remove warning about native assembler,
4634 since it also occurs in the xconfig file.
4636 * findvar.c (registers): Allocate some slop after `registers'
4637 to prevent stray accesses from trashing the next variable.
4639 * tm-68k.h (REGISTER_BYTES): Allocate the right number of bytes
4640 on the sun-3, by changing the #ifdef from `sun3' (which is not
4641 defined by cc) to `sun'. Symptom was trashed builtin_type_XXX
4642 vars, which happened to follow `registers' in the executable.
4644 * readline/history.c (history_search): Heed gcc-2's advice
4645 and parenthesize && inside ||).
4647 * am29k-opcode.h, am29k-pinsn.c, am29k-tdep.c, remote-eb.c,
4648 tm-29k.c: Insert FSF copyright headers.
4650 * remote-eb.c: Better comments.
4652 * Makefile.dist: Update to 3.91.6.
4653 * TODO: note PREPARE_TO_STORE problem.
4655 Thu Sep 13 09:52:33 1990 Jim Kingdon (kingdon at cygint)
4657 * stack.c (frame_info): Only use FRAME_FIND_SAVED_REGS if defined.
4659 * remote.c: Wrap the whole file in #if !defined (SPECIAL_REMOTE).
4661 * infrun.c (wait_for_inferior, at end): Don't set up
4662 prev_* if the inferior no longer exists.
4664 * inferior.h (CALL_DUMMY_LOCATION): New macro, to replace
4665 CANNOT_EXECUTE_STACK.
4666 valops.c (call_function): Use it.
4668 * tm-convex.h: Add CALL_DUMMY_LENGTH for use by PC_IN_CALL_DUMMY.
4670 * inferior.h (PC_IN_CALL_DUMMY): New macro.
4671 infrun.c (wait_for_inferior, 2 places): Use it.
4673 * values.c (value_being_returned): Only use
4674 EXTRACT_STRUCT_VALUE_ADDRESS if defined.
4676 * Move PREPARE_TO_STORE from xm-sun3.h to tm-sun3.h to do the
4677 right thing for remote-eb.c.
4679 * sun3-xdep.c: Remove extraneous call to remote_store_registers.
4680 * sun386-xdep.c, hp300hpux-xdep.c, sparc-xdep.c: Ditto.
4682 * blockframe.c: Put get_frame_saved_regs inside #if !defined
4683 (FRAME_FIND_SAVED_REGS).
4685 * findvar.c ({fetch,store}_registers): Check for
4686 REMOTE_{FETCH_STORE}_REGISTER macro.
4688 * findvar.c (get_saved_register): Add argument lval and
4689 change meaning of argument addr.
4690 findvar.c: Change calls to get_saved_register to reflect
4691 new calling convention.
4692 valops.c (value_assign): Use get_saved_register instead of
4693 find_saved_register.
4695 Sun Sep 2 12:40:20 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4697 * coffread.c (read_one_sym): Make temp_aux an AUXENT, not
4698 an (uninitialized) pointer to one. Use "&" when passing it
4701 Fri Aug 31 22:57:54 1990 Jim Kingdon (kingdon at cygint.cygnus.com)
4703 * coffread.c (getfilename): Use DGUX x_offset and x_name if
4706 * coffread.c (symbol_file_command): Put semicolon after
4708 Put safe_to_init_tdesc_context in #if defined (TDESC).
4709 Put #ifdef TDESCs in 1st column for non-ANSI cpp's.
4710 coffread.c: #include <sys/stat.h>.
4711 (read_coff_symtab): Typo: in_source_files -> in_source_file.
4712 Add missing ')' in check for "lc%" and friends. Remove
4714 Declare read_one_sym() at top of file.
4715 (read_file_hdr): Put in extra #ifdefs so MC68MAGIC and
4716 MC68WRMAGIC can have the same value without causing a duplicate
4719 Thu Sep 13 15:55:36 1990 John Gilmore (gnu at cygint)
4721 * Allow a Makefile to be built without building the
4722 tm and xm file links that screw up builds in subdirectories.
4723 This is done with `config.gdb none', then you can do things
4724 like `make gdb.tar.Z'.
4725 * tconfig/none: Config file for no target system
4726 * xconfig/none: Config file for no host system
4727 * config.gdb: If no TM or XM files are called out by the
4728 host or target file, don't make links for them.
4730 * cplus-dem.c: Add documentation.
4732 * dbxread.c (read_ofile_symtab): Turn a fatal error into a
4733 simple error, so the user's gdb doesn't crash due to some object
4734 file problem (e.g. somebody is rebuilding the file out from under
4737 * printcmd.c (print_address_symbolic): demangle the symbol.
4739 * Makefile.dist (OTHERS): Remove tdesc-lib because it has
4740 Motorola copyrights in it. Make "make gdb.tar.Z" work.
4741 (alldeps.mak): sort and uniq all results from this; duplicates
4742 hose gdb.tar.Z link building. Remove RCS files from
4743 tconfig and xconfig. Add config files for sun386. Add
4744 a few odd files to OTHERS and HFILES.
4746 Mon Sep 10 21:20:24 1990 John Gilmore (gnu at cygint)
4748 * Makefile.dist: Pull solib.c to tconfig/sun?os4.
4749 Roll version number to 3.91.5. Make lint work in bindir.
4751 * README: Document cross-debugging and new file structure.
4753 * blockframe.c: Lint. Include "value.h" to declare read_register.
4754 (find_pc_partial_function): remove duplicate line.
4756 * command.h: Lint. Declare error_no_arg and dont_repeat.
4758 * tm-news.h: Remove inadvertently duplicated stuff.
4760 * mipsread.c: Remove cache_pc_function stuff, now done cleanly.
4761 Clean up usage of misc_function_type. Declare some CORE_ADDRs.
4763 * config.gdb: Allow `config.gdb host target' form. Clean
4764 up previous change that printed bogus messages when you just said
4767 * core.c: #include "command.h" for lint.
4770 * main.c: Remove some casts of enums. Lint.
4777 * printcmd.c (initialize_printcmd): Fix thinko in inspect cmd.
4779 * sparc-tdep.c (isannulled): Take instruction as parameter, don't
4780 read it from memory. This will allow us to save ptrace calls
4781 eventually. Changed caller single_step too.
4783 * sparc-xdep.c (fetch_inferior_registers): Avoid reading regs
4784 that we aren't going to use, saving many ptrace calls, especially
4785 when watchpointing or single stepping. Use some #define's for
4787 (store_inferior_registers): Ditto.
4788 (core_file_command): Use some #define's for constants.
4790 * tm-sparc.h: Add #define's for some register numbers, so we
4791 can eliminate the use of random constants in sparc-xdep.c.
4793 * stack.c (frame_command, print_frame_info, up_command,
4794 down_command) Remove frame_changed, since it
4795 causes a bug and doesn't seem to do anything useful. In some
4796 places it was used as a flag, in others as a stack level (?).
4798 * utils.c: Use MISSING_VPRINTF rather than HAVE_VPRINTF, so the
4799 default is to use the portable (vprintf) version rather than the
4801 * xm-news.h (MISSING_VPRINTF): Add.
4803 * valprint.c (val_print): Demangle fancy vtbl printouts. Lint.
4805 Sat Sep 8 00:24:12 1990 John Gilmore (gnu at cygint)
4807 * Remove stuff that forces -Bstatic linking of gdb, and warnings
4808 about linking debugged programs -Bstatic in the sun?os4 config
4809 files in tconfig and xconfig subdirectories.
4811 * main.c (main): Remove unreached exit(0) now that we exit
4814 * Create TODO file for online bug list. There are too many
4815 "little" bugs to keep track of on paper.
4817 * Change Projects file to refer to bug-gdb@cygnus.com
4818 rather than kingdon@ai.
4820 Fri Sep 7 23:35:15 1990 John Gilmore (gnu at cygint)
4822 * Makefile.dist (VERSION): 3.91.4 now.
4824 * symtab.c (init_misc_bunches): Rename from init_misc_functions.
4825 (condense_misc_bunches): Add sanity check that misc_count is
4826 the same as the number of symbols in the bunch.
4828 * coffread.c: rename init_misc_bunches. Pass an argument
4829 to condense_misc_bunches (a zero).
4831 * dbxread.c (partial_symbol_file_read): Call init_misc_bunches
4832 every time we are called; don't rely on our caller to do it.
4833 (add_file): Remove call to init_misc_bunches.
4835 * mipsread.c: Only warn, don't error, if unknown symbol types.
4836 This keeps an old gdb from falling on its face if it sees newly
4837 extended symbol info. Rename init_misc_bunches.
4839 Fri Sep 7 22:58:15 1990 John Gilmore (gnu at cygint)
4841 * Merge in changes from Per Bothner for DECstations and other
4842 MIPS stuff. The rest is Bothner speaking:
4844 The next message is a merger of Alessando Forin's mips port with
4845 mine. I've tried to use my good if biased judgment to get
4846 the best of both. It *does* need testing.
4848 Some of the changes are general, *not* mips-specific.
4851 Didn't believe in little-endian bit order.
4852 There are still inconsistencies about whether flags
4853 like BITS_BIG_ENDIAN are integer (#if ...) or
4854 boolean (#ifdef ...). I tried to paper over them.
4856 dbxread.c,coffread.c,mipsread.c,symtab.c,symtab.h:
4857 Moved some misc_function code that was common to
4858 {dbx,coff,mips}read.c to symtab.c.
4859 In the process, I think I cleaned things up a bit.
4860 At the same time, moved obsavestring and obconcat to symtab.c.
4863 Removed obsolete condense_addl_misc_bunches (use
4864 condense_misc_bunches(1) instead).
4867 Needed to include <sys/dir>, at least on DECstations.
4869 valops.c, mips-tdep.c, tm-mips.h:
4870 Added PUSH_ARGUMENTS macro to support funny argument-pushing
4871 conventions (when STACK_ALIGN is insufficient).
4872 Needed on mips, where doubles need 8-byte alignment,
4873 but ints only need 4.
4876 Removed cruft that was not being used.
4877 Merged in many fixes (most from Frank Yellin, fy@lucid.com).
4880 Print $ before register-names (I think that makes things a little
4882 Never print two instructions, even if one delays.
4883 Removed hex-disassemble set_cmd. (This is not mips-specific,
4884 so I think the argument is whether it is generally worthwhile or not.
4885 I'm inclined to think not, given how easy it is to
4886 convert between radixes in gdb.)
4889 This is basically Alessando's code.
4890 It doesn't use obstacks; I changed it to use obstacks
4891 in a few minor places where using malloc causes a
4892 memory leak. (Probably, more places could/should be changed.)
4893 I added record_misc_function where it was missing.
4894 In symbol_file_command and add_file_command, I tried
4895 to make the code consistent with more recent versions.
4896 Minor sylistic changes in parse_procedure.
4897 Make a .gdbinfo. psuedo-symbol point back to the real
4898 procedure symbol (using the isym field).
4901 This is basically from my port, but with a lot of details
4902 and a number of routines merged in from Alessando's version.
4903 I basically used my code "raw" backtrace (use heuristics
4904 from the actual code, rather than symbol table info) - though
4905 the idea is Alessandro's. I feel my code is a little cleaner
4906 here, particularly in being a little more flexible, such as being
4907 able to handle gcc-produced code (which it now can).
4908 It also doesn't do frame caching (which is not useful
4909 more recent gdb versions).
4910 I also used my code for push_/pop_dummy, more or less.
4911 I tried to incorporate AF's code for testing sigtramp
4912 while backtracing; I probably got it wrong.
4913 Added mips_print_register, which tries to scrunch as much
4914 information as possible on a screen...
4915 Removed the skip-prologue set_cmd. As with hex-disassemble (see
4916 under mips-pinsn.c), I don't see anything mips-specific here,
4917 and I don't see it being all that useful anyway.
4920 Added a $fp psuedo-reg distinct from $fp (nice for gcc).
4921 Use more register names (rather than hard-cases numbers).
4923 Thu Sep 6 18:33:15 1990 John Gilmore (gnu at cygint)
4925 * Hack up 3.90.11 changes:
4927 * Makefile.dist (depend): parameterize $(GCC).
4928 Add solib.c and solib.o.
4929 (readline): Fix vpath for both absolute or relative SRCDIR.
4931 * blockframe.c: Fix from Schaefer@asc.slb.com for shared libs.
4932 Also, let the part I didn't understand at least compile so
4933 I can test the rest. FIXME.
4935 * dbxread.c: Fix thinko using strcmp.
4936 (init_psymbol_list): declare static.
4937 (partial_symbol_file_open): Comment cleanups better, avoid
4938 cleaning up the string table since the caller will do that.
4939 Move the stat for mod time into symbol_file_command, temporarily.
4940 (There should be a mod time for each symbol file, eventually,
4941 to control its rereading. FIXME.)
4943 * infptrace.c (PT_WRITE_D): use same value as PT_WRITE_I for
4944 SunOS, which gives error for shared libs otherwise. (From
4945 Schaefer, probably FIXME needs work for portability.)
4947 * solib.c: Move #include "param.h" to work.
4948 Lowercase all the Uppercase Letters In the Messages.
4949 (find_solib): Clean up inferior_so_name for debug printouts.
4950 Allow no argument, to mean all shared libraries.

4978 Put parens around gcc_p in expansion.
4980 Thu May 24 15:44:51 1990 Jim Kingdon (kingdon at mole.ai.mit.edu)
4982 * utils.c (lines_to_list): Return 10 if lines_per_page == 0.
4984 Wed May 23 16:36:04 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
4986 * Changes for Sun shared libraries:
4987 blockframe.c (find_pc_partial_function): If a non-text symbol
4988 is found, set *address = pc - FUNCTION_START_OFFSET.
4989 breakpoint.c (insert_breakpoints) [DISABLE_UNSETTABLE_BREAK]:
4990 Disable breakpoints instead of giving an error.
4991 source.c (select_source_symtab): Initialize cs_pst.
4992 symmisc.c: Call CLEAR_SOLIB if defined.
4993 symtab.h: Make text{low,high} CORE_ADDR not int.
4994 (psymtab): New field addr.
4996 dbxread.c: Move DECLARE_FILE_HEADERS outside functions.
4997 (record_misc_function): Give correct type for N_DATA symbols.
4998 (condense_misc_bunches): do "misc_function_count = j" regardless
5000 Take code which is shared between symbol_file_command and
5001 add_file_command and put it into partial_symbol_file_{open,read}.
5002 Split add_file_command into add_file_command and add_file.
5003 Make psymtab_to_symtab read in the string table if the file
5005 Two new parameters to read_dbx_symtab and start_psymtab.

5008 Tue May 22 17:43:03 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5010 * infcmd.c: Change cont_command to continue_command and "cont"
5013 Mon May 21 14:41:41 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5015 * breakpoint.c (enable_breakpoint): Get value of watchpoint.
5017 * defs.h [sparc]: Use <alloca.h> regardless of __GNUC__.
5019 * values.c (USE_STRUCT_CONVENTION): Check for structures of
5020 size 1,2,4,8 rather than size < 8.
5022 * dbxread.c (dbx_lookup_type): Do f->length *= 2 as many times
5023 as necessary, not just once.
5025 * sparc-opcode.h: Add a bunch of new opcodes which Sun as supports.
5027 Thu May 17 15:04:09 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5029 * {t,x}m-sun386.h, sun386-xdep.c, {x,t}config/sun386
5031 * tm-news.h: Add CALL_DUMMY_*.
5033 * tm-68k.h: Remove duplicate comment at FRAME_FIND_SAVED_REGS.
5035 * config.gdb: In list_host, list_target, use ${i}, not $i.
5037 Tue May 15 21:27:12 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5039 * source.c (find_source_lines) [BROKEN_LARGE_ALLOCA]: Use xmalloc.
5041 * sparc-opcode.h: Change all store floating-point state register
5042 instructions to have the right match & lose fields.
5044 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5046 * Makefile.dist: Move -I${srcdir} to GLOBAL_CFLAGS and pass
5048 config.gdb: If srcdir != ., create readline directory and
5049 copy a makefile into it.
5051 * wait.h, infrun.c: Change WRETCODE to WEXITSTATUS for
5052 consistency with POSIX.
5054 * breakpoint.c (bpstat_stop_status): Disable watchpoint
5055 when we exit its exp_valid_block.
5057 Tue Sep 4 11:46:46 1990 John Gilmore (gnu at cygint)
5059 * Makefile.dist: Bump version to 3.91.3.
5061 * Clean up handling of breakpoint commands (somewhat).
5062 Prompted by Tiemann bug report "cont 10" doesn't work any more.
5064 inferior.h: Add breakpoint_proceeded to inferior status struct
5065 and globals; save it and restore it.
5066 (clear_breakpoint_commands): Cleanup, remove old #define.
5068 infrun.c (clear_proceed_status): Set breakpoint_proceeded.
5069 (save_inferior_status, restore_inferior_status): handle it also.
5070 (proceed): Remove earlier code that set breakpoint_proceeded.
5071 It is now set only in clear_proceed_status.
5072 (clear_proceed_status): Cleanup, use bpstat_clear rather
5073 than clear_breakpoint_commands. No callers need the stop_bpstat
5074 between clear_proceed_status and proceed.
5076 infcmd.c: Add breakpoint_proceeded definition and comment.
5077 (cont_command, jump_command, signal_command): Move call to
5078 clear_proceed_status right next to call to proceed.
5080 breakpoint.c (bpstat_do_actions): Avoid clobbering our
5081 caller's argument while running down the chain of breakpoints.
5082 Use new variable "breakpoint_proceeded" to determine when
5083 a command that it executes moves the inferior past the
5085 (bpstat_clear): Handle NULL argument.
5086 (bpstat_clear_actions): Avoid useless call to
5087 breakpoint_auto_delete.
5088 (delete_breakpoint): Clean up bpstat's that are pointing to
5089 the deleted breakpoint from the stop_bpstat chain.
5090 (breakpoint_auto_delete): Simplify.
5092 * Clean up handling of EOF, error on stdin, etc. This was
5093 prompted by a network problem that caused gdb to go into an
5094 infinite loop filling up its malloc'd memory.
5096 main.c (return_to_top_level): Cleanup: call bpstat_clear_actions,
5097 not clear_breakpoints_commands, which is now gone.
5098 (main): If command_loop returns (e.g. from EOF on stdin), do
5099 a quit_command (looping back to command_loop if quit_command
5100 doesn't really quit).
5101 (command_loop): check result from command_line_input and
5102 exit if it returns NULL, rather than passing the NULL to
5104 (gdb_readline): Free malloc'd result space before returning
5107 * utils.c (query): Handle C-d to mean "yes", just as if the
5108 input was not a terminal. Also avoid infinite loop if EOF
5109 occurs in mid-input-line before newline. This allows
5110 query to be used at EOF on stdin with reasonable results.
5112 * infrun.c (proceed): Set breakpoint_proceeded.
5114 * values.c (value_as_long): Avoid infinite recursion for enums.
5115 (_initialize_values): Fix typo in help msg (kingdon).
5117 * Makefile.dist (RL_LIB): Use RL_LIB_DEP for dependencies,
5118 RL_LIB for linking. This allows -lreadline for linking
5119 and nothing for dependencies, once readline is a real library.
5121 * config.gdb: Jim Kingdon: give useful error message if the
5122 host or target type is not recognized.
5124 * defs.h (alloca): SPARC <alloca.h> does not declare alloca,
5125 it just defines it. Dumb, but deal with it.
5127 * Jim Kingdon suggests:
5128 in xconfig/sun3os4, CFLAGS should be XM_CFLAGS.
5130 Wed Aug 29 18:03:27 1990 John Gilmore (gnu at cygint)
5132 * Makefile.dist (VERSION): Bump version # to 3.91.2.
5134 * Clean up Bothner's changes.
5136 * blockframe.c (clear_pc_function_cache): New function.
5137 * blockframe.c: remake cache_pc_function_* static.
5138 * dbxread.c (symbol_file_command): remove references to
5139 cache_pc_function_* variables.
5140 * dbxread.c (read_struct_type): Use VOFFSET_STATIC.
5141 * printcmd.c: Avoid kludging a global variable (addressprint)
5142 to avoid printing the address of a string twice. Instead,
5143 pass the format letter 's' down low enough that it can be seen
5144 to avoid this problem.
5145 (print_formatted): Pass format arg to value_print.
5146 (restore_addressprint): Remove function.
5147 (do_examine): Avoid hacking addressprint, cleanups and such.
5148 (print_frame_args): Add a comment to a Bothner change.
5149 * symtab.h: define VOFFSET_STATIC and use it instead of "-1".
5150 * symmisc.c (free_all_symtabs): Call clear_pc_function_cache
5151 to wipe out the values cached in blockframe.c.
5152 * symtab.c (find_method): Add comment saying how big you must
5153 allocate to be "big enough". Per being terse again.
5154 * valprint.c (val_print): Handle format letter "s" to print
5155 strings without addresses. Add comment to vtbl printing code
5156 which casts with wild abandon. Rearrange reference-printing
5158 @0xaddr: value (print w/addressprint)
5159 value (print w/~addressprint)
5160 @0xaddr (parameter lists w/addressprint)
5161 or nothing (parameter lists w/o addressprint)
5163 Tue Aug 28 10:47:18 1990 John Gilmore (gnu at cygint)
5165 * Merge more changes from Per Bothner:
5167 Gdb's handling of TYPE_CODE_REF was so counter-C++ (and otherwise
5168 annoying) that I tried to improve it. Here are my suggestions.
5170 These patches all attempt to handle TYPE_CODE_REF (as in C++) better.
5173 Do automatic de-reference when taking the address of a reference.
5175 Don't deref_ref when printing parameter lists.
5177 More attempts at treating refernences properly.
5179 In val_print, if deref_ref==0, don't print dangling " = ".
5181 Add COERCE_REF macro, which de-references an REF.
5183 * Merge changes from Per Bothner:
5185 * Fixed (Sony news)-specific configuration problems.
5186 * Fixed other problems with using vanilla pcc and libc (enum problems;
5187 assumption that vsprintf exists).
5188 * Some major speed-ups (finc_pc_partial_function now caches a match;
5189 parsing avoids duplicate symbol_lookup calls).
5190 * Changed handling of baseclasses (no longer use baseclasses field
5191 of struct type, use the first n_baseclasses fields instead).
5192 * Various minor changes/fixes, most C++-related.
5195 Cache the most previous match from find_pc_partial_function.
5196 (Save both low and high ends of matching function's pc range.)
5197 This speeds up the loop of infrun.c:wait_for_inferior quite
5198 a bit, and makes step/next commands much zippier.
5200 Added an enum->int cast (otherwise, some compilers barf).
5202 No longer set baseclass offset to 0, since multiple
5203 inheritance now mostly works.
5204 Added a number of casts, to shut up compiler warnings
5205 (after stabs where made enums, not ints).
5206 When discarding a symbol table (in symbol_file_command),
5207 must clear the cache introduced in blockframe.c.
5208 Don't convert $vtbl_ptr_type to vtbl any more.
5209 Get rid of TYPE_BASECLASEES and baseclass_vec (see also symtab.h).
5210 Mask off sign bit emitted by g++ for virtual table offset.
5211 Set voffset to -1 (not 1) for static member functions.
5213 Changed parsing/lexing of names to avoid doing symbol lookup twice
5214 (once when lexing to determine symbol class, once for real).
5215 Now only call symbol_lookup once. Fields of 'this' win especially big.
5217 Subpress printing addr twice in the case of 'x/s addr'.
5219 lookup_basetype_type is no longer used.
5220 Add find_methods as recursive helper function to decode_line_1.
5221 This allows multiple inheritance to work.
5222 Also, once one or more matches has been found, do not look in
5223 base-classes. (Baseclass methods would be overridden, anyway.)
5225 Removed baseclasses array in struct type.
5226 Instead of using baseclasses[i], use fields[i-1].
5227 Added virtual_field_bits[i] to indicate if the i'th baseclass is virtual.
5228 Changed sign convention of voffset (previous was inconsistent).
5230 Some macros (CALL_DUMMY and relatives) were missing. Put them back.
5232 Used to assume existence of vsprintf. Re-written to not need it
5233 if HAVE_VPRINTF is undefined.
5235 typecmp was too pessimistic. Made it less so.
5237 Don't print space after address.
5238 If vtable points to a misc symbol (with 0 offset), print it,
5239 since that indicates the actual class of the object.
5240 Changed ype_print_derivation_info to use new inheritance
5241 scheme (without baseclasses vector).
5243 In value_primitive_field, fixed some bugs left over from previous set of fixes.
5244 Also, changes needed because TYPE_BASECLASSES were removed.
5246 REGISTER_U_ADDR didn't work for PC. Rewrote to use an array.
5248 Tue Aug 21 20:08:54 1990 John Gilmore (gnu at cygint)
5251 If there is no path set, and the symbols don't indicate what directory
5252 a file was compiled in, look in the current directory. But either
5253 a path or a known compilation directory will prevent this.
5256 Three independent bug fixes:
5257 * Remove the #if 0 block that breaks some stuff.
5258 * SunOS 4.1 fixed the promoted-parameter-wrong-addr bug in Sun C;
5259 adapt gdb to either SunOS 4.0.* or 4.1.
5260 * MAX_OF_TYPE and MIN_OF_TYPE thinko. By tedg@sun, I think.
5263 Instantiate the class T when looking for methods in it. (Tiemann@sun)
5266 (type_print) Demangle the name being printed.
5267 (type_print_base) Handle botched demangling without coredump (tiemann).
5270 (check_stub_method): Document routine.
5271 (tiemann) fix bug for no-arg functions
5272 Avoid clobbering beyond end of malloc'd storage.
5273 Terminate the argument list properly.
5275 Sat Aug 18 01:29:59 1990 Per Bothner (bothner@cs.wisc.edu)
5277 * Changes merged by John Gilmore:
5280 In breakpoint_1, use new print_address_symbolic instead
5281 of find_pc_partial_function. (This forces use of assembler-level
5282 addresses, and avoids misleading non-mangled source-level names.)
5284 Generalize ansi argument such that -1 means skip arglist totally.
5285 Removed global variable print_ansi_qualifiers (which made
5286 code non-reentrant), in favor of extra explicit arguments
5287 to internal routines.
5289 Add new helper function print_address_symbolic.
5290 Use find_pc_misc_function instead of find_pc_partial_function
5291 (since we want assembler-level symbols here).
5293 Print unknown function as just "f (...)", not "f (...) (...)".
5294 Use new fputs_demangled explicitly.
5296 Fixed a typing violation (problem: value.h cannot be imported
5297 without renaming many variable in this file).
5298 lookup_symbol: If no matching misc_func, look for a C++-mangled name.
5299 decode_line_1: Moved forward some never-reached code.
5300 Made decode_line_2 skip function prologues correctly.
5302 fputs_filtered should not demangle by default.
5303 Add new fputs_demangled to demangle on demand..
5305 Change value_struct_elt to use value_primitive_field (using recursive
5306 utility function search_struct_field). This allows foo.bar to work
5307 for multiple inheritance (so far only for data fields).
5308 Change check_field in the same way (recursive helper function
5309 to support multiple inheritance).
5310 (Note: there are more of these problems that I haven't fixed.
5311 Any code that says TYPE_BASECLASS (t, 1) is probably wrong.)
5312 value_of_this: 'this' symbol name is now just "this", note "$this".
5314 Don't print static members.
5315 Avoid printing "members of <type>" if there are none.
5316 Simplified type_print_derivation_info by merging duplicate code.
5317 Remove useless blank lines in type_print_base (ptype command).
5319 Added declaration of new routine value_primitive_field.
5321 Added value_primitive_field which is generalized version of
5322 value_field that can handle multiple inheritance (non-zero offsets etc).
5323 Re-implemented value_field to call value_primitive_field.
5325 Fri Aug 17 23:33:44 1990 John Gilmore (gnu at cygint)
5327 * infcmd.c -- insert else to avoid 'delete env' coredump when you
5328 delete the whole environment. Karl Berry reported the bug.
5329 * source.c - fix openp to avoid //'s in filenames, which
5330 trigger an Emacs bug causing it to not be able to find files
5331 when running gdb in a window.
5332 * dbxread.c - zap the #if 0 that botches the add-file code.
5333 It seems to work a lot better without all the code commented out.
5335 Fri Jul 20 16:58:46 1990 John Gilmore (gnu at cygnus.com)
5337 * Merge Tiemann's and Ted Goldstein's changes, detailed below,
5340 Tue Jul 17 19:34:33 1990 Ted Goldstein (tedg at golem)
5342 * Makefile - added a ${CFLAGS} to a couple of entries,
5343 added remote-sa.sparc.c
5344 * added remote.sa-sparc.c, a modification of remote.c
5345 which conducts a dialog directly with the SparcStation prom.
5346 * breakpoint.c, infrun.c, sparcdep.c added
5347 remote_insert_breakpoint(), and remote_remove_breakpoint()
5348 to breakpoint.c instead of directly writing breakpoint instructions.
5349 * sparcdep.c on remote_debugging,there is no need
5350 to remove signle step breakpoint instructions.
5351 * main.c added "-epoch" flag and "int epoch_interface" to main.c
5353 * printcmd.c - epoch interface sends lisp expressions to open up
5354 epoch windows on inspection.
5355 * valprint.c - added arrayprint, and addressprint and made adding
5356 format controls easier
5357 * wait.h added a couple of undef's because we were getting
5358 complaints about WSTOPSIG and WTERMSIG begin redefined.
5361 Wed Jul 4 05:27:51 1990 Michael Tiemann (tiemann at masham)
5363 * symtab.c (decode_line_1): Add support for handling method stubs
5364 in the type information.
5366 Tue Jul 3 09:39:18 1990 Michael Tiemann (tiemann at masham)
5368 * values.c (baseclass_addr): Run loop from INDEX+1 to
5369 N_BASECLASSES; otherwise, we can still get into a loop.
5370 @@ This should be restructured to use a cleaner search strategy.
5372 Sun Jul 1 12:28:51 1990 Michael Tiemann (tiemann at masham)
5374 * dbxread.c (define_symbol,read_type): Grok GNU C++'s new
5375 abbreviation "Tt" for tags which have the same name as their
5378 Fri Jun 29 01:03:46 1990 Michael Tiemann (tiemann at masham)
5380 * symtab.c (list_symbols): add ability to set breakpoints on all
5381 the functions which match a particular regular expression.
5383 Tue Jun 26 04:26:29 1990 Michael Tiemann (tiemann at masham)
5385 * cplus-dem.c (cplus_demangle): New parameter ANSI says whether we
5386 should print ANSI qualifiers (such as `const' and `volatile').
5387 All callers changed to call with ANSI == 1, except from
5388 `check_method_stub', which uses old-style syntax.
5390 * symseg.h (struct fn_field): Remove unneccessary `args' field.
5391 * symtab.h (TYPE_FN_FIELD_ARGS): Redefined.
5393 * values.c (check_stub_method): New function.
5395 * cplus-dem.c (do_type): Handle "long long" (encoded as 'x').
5397 * dbxread.c (read_type): Handle new GNU C++ method type stubs.
5398 * valprint (type_print_base): Ditto.
5400 * symtab.c (gdb_mangle_typename): New function.
5402 Tue Jun 5 00:18:43 1990 Michael Tiemann (tiemann at gzilla)
5404 * breakpoint.c (catch_command): New function. Provides a
5405 mechanism to set breakpoints based on catch clauses.
5406 (disable_catch): Similar, but disables breakpoints on catch
5408 (delete_catch): Similar, but deleted breakpoints on catch clauses.
5410 Sun Jun 3 22:54:08 1990 Michael Tiemann (tiemann at gzilla)
5412 * blockframe.c (blockvector_for_pc): New function.
5413 * blockframe.c (block_for_pc): Changed to call
5414 `blockvector_for_pc' and get the block itself.
5416 * stack.c (catch_info): New function. Prints info about
5417 exceptions which can be caught in the current frame.
5418 * stack.c (print_frame_label_vars): New function. Similar to
5419 `print_frame_local_vars'.
5420 * stack.c (print_block_frame_labels): Prints out labels that are
5421 defined in this frame. These labels are exceptions that can be
5424 * dbxread.c: Updated to handle N_CATCH symtab types.
5426 Thu May 3 22:10:00 1990 Michael Tiemann (tiemann at teacake)
5428 * valprint.c (everywhere): TYPE_NAME (TYPE) no longer comes in the
5429 form "struct ..." for GNU C++. Don't flush any part of TYPE_NAME
5430 when printing the type.
5432 Wed May 2 22:43:04 1990 Michael Tiemann (tiemann at teacake)
5434 * valprint.c (val_print): Use `baseclass_addr' to access the
5435 baseclasses pointed to via the derived class object at VALADDR.
5437 * values.c (baseclass_addr): New function. Casts derived pointers
5438 to baseclass pointers taking virtual baseclasses and multiple
5439 inheritance into account.
5441 Sat May 5 12:39:18 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5445 Fri May 4 12:12:55 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5447 * breakpoint.c (watch_command, bpstat_stop_status): Deal with
5448 exp_valid_block field correctly.
5450 * infrun.c (wait_for_inferior): When checking "don't even think
5451 about breakpoints" if stop_signal == SIGTRAP && trap_expected,
5452 also check step_resume_breakpoint.
5453 Insert breakpoints and continue (not step) if
5454 step_resume_break_address != NULL, even if another_trap.
5455 If trap_expected and we enter sigtramp, then set up a
5457 If trap_expected is set when we hit the step_resume_break,
5459 When calling resume and trap_expected says tell resume to step
5460 (2 places), also check step_resume_break_address.
5462 * infrun.c (wait_for_inferior): Don't set
5463 prev_{pc,sp,func_{start,name}} before calling wait ().
5464 Do set them after exiting loop.
5465 Move their declarations outside functions.
5466 (start_inferior): Initialize them.
5468 Thu May 3 00:15:11 1990 Jim Kingdon (kingdon at pogo.ai.mit.edu)
5470 * infrun.c (wait_for_inferior, after check for trap_expected > 1):
5471 Restore old code which distinguishes between trap_expected and
5472 running_in_shell, just make the latter take any non-TRAP signal,
5475 * values.c (allocate_value): Zero VALUE_OPTIMIZED_OUT flag.
5477 * Makefile.dist (pinsn.o): Use PINSN_CC to compile.
5478 xconfig/3b1 (CC,PINSN_CC): Define.
5480 * xconfig/altos, altos-dep.c: Rename altos-dep.c to altos-xdep.c.
5484 * breakpoint.c (bpstat_stop_status),
