391 * main.c (defined_command): Lower-case the user's
392 new command before entering it. Needed because
393 command lookup is case-insensitive (and also lower-cases).

500 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
502 More C++ improvements (pointers to members, qualified names).
503 * c-exp.y: Support exp.type::name and exp->type::name
504 syntaxes. (Unfortunately, doesn't work for static members.)
505 * c-exp.y, eval.c: Make type::~type work better.
506 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
507 value_static_field by value_struct_elt_for_reference.
508 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
509 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
510 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
511 for OP_SCOPE operand; no point in it now that we use lazy
512 reading of values, and use "reference to member" objects.
513 * gdbtypes.h: Clarify comment.
514 * valops.c: Change value_struct_elt_for_address to return
515 a reference (or variable), rather than a pointer. Change
516 the name to value_struct_elt_for_reference to reflect this.
517 Returning a reference instead of a address provides a
518 generalization, since we can use the routine for both
519 class::name as well as &class::name.
520 Also, recurse to handle multiple inheritance properly.
521 * valprint.c: Moved code to print pointer-to-members
522 to new function point_class_member. This allows a
523 "reference-to-member" to be printed using the same code.
524 * valprint.c (type_print_varspec_prefix): Avoid printing
525 "struct " for domains of class-member types.
526 * valops.c (search_struct_field): Inline code for simplified
527 version of value_static_field (which can then be deleted).
528 * value.h: Rename value_struct_elt_for_address to
529 value_struct_elt_for_reference. Delete value_static_field.
530 * values.c: Remove no longer used function value_static_field.

539 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
540 Pass pointer to struct objfile rather than pointer to sym_fns.
541 Change references inside each function accordingly. Allocate any
542 symbol file specific info in the per-objfile memory region.
543 * dbxread.c (free_and_init_header_files): Break function into
544 free_header_files(), called from dbx_symfile_finish(), and
545 init_header_files(), called from dbx_new_init().
546 * dbxread.c (dbx_new_init): Move deallocation things to new
547 dbx_symfile_finish function.
548 * elfread.c (elf_new_init): Call buildsym_new_init().
549 * objfiles.c (free_objfile): Call the appropriate symfile_finish()
550 routine for the objfile before deallocating other stuff.
551 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
552 * symfile.h: Move struct sym_fns to before struct objfile def.
553 Add sym_finish function pointer and change prototypes of other
554 function pointers to reflect passing struct objfile pointer rather
555 than struct sym_fns pointer.
556 * symfile.c: Remove now obsolete symtab_fns pointer.
557 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
558 locates the correct sym_fns struct for the given objfile.
559 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
560 for better support of mapped symbol tables.
561 * symfile.c (symbol_file_command): Remove obsolete code using
563 * symfile.h: Remove duplicate declarations for symfile_objfile,
564 entry_point, and object_files.
565 * target.c (target_info): Compare symfile_objfile to NULL.
566 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
567 aixcoff_symfile_finish().

822 message back on, after cleaning up BFD.
824 * breakpoint.c (breakpoint_re_set): Removed (at least for now)

828 * defs.h: Put back declarations of malloc and realloc,
829 but protected by #ifndef MALLOC_INCOMPATIBLE.
830 * objfiles.c: Undo previous change: Use malloc/realloc
831 for objfile malloc/realloc fields (but add a cast).
832 * xcoffexec.c: Suppress an error message (for now).
834 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
836 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
837 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
838 * buildsym.c: Use smash_to_pointer_type() to handle forward type
840 * xcoffread.c: Modifications to C_DECL storage class handling, and
841 introduction of an old smash_to_pointer_type() routine.
843 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
844 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
845 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
846 parameters have been modified.
848 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
849 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
850 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
851 and fetch_inferior_registers() always fetched all the registers
852 resulting valid register values at hand all the time. Pushing a dummy
853 frame did not require validating all register values first. After
854 putting the above mechanism into action, we didn't have valid registers
855 values always ready. Thus, all registers need to be fetched before
856 pushing a dummy frame now.

859 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
860 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
861 the starting address (actual frame address) of a frame.
862 * rs6000-tdep.c: modifications to function_frame_info() to see if
863 function reserves a frame pointer register (alloca register)
864 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
865 FRAME_LOCALS_ADDRESS has been updated to support debugging of
866 functions with alloca() calls.
868 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
870 * xm-sysv4.h: Provide definitions/prototypes for host environment
871 functions for which no definitions or prototypes are provided in
872 any currently included gdb or host environment header files.
873 For SVR4, this currently includes malloc and realloc, which cannot
874 be portably prototyped in any gdb include file.
876 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
878 * buildsym.h: Remove obsolete variable file_stabs.
880 * Makefile.in: Move place where configure merges in host-
881 and target-dependent fragments later, so the latter
882 can override (say) GNU_MALLOC.
883 * config/mh-rs6000: Use system malloc. Otherwise, I
884 ended up with *two* incompatible versions of malloc
885 (functions in libc would call the malloc in libc).
886 I assume this is a shared library problem.
888 * remote.c: Fix (presumed) typo.
889 * objfiles.c: Use xmalloc/xrealloc instead of
890 malloc/realloc (since the latter are no longer declared).
892 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
893 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
894 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
895 handle individual registers.
896 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
897 correctly in case it wasn't cached yet. (A problem showed up
898 after fetching individual registers.)
899 * buildsym.c: Disable type_synonym_name's type name overwriting
900 in cases it is unnecesary. rs6000 portation doesn't use
901 type_synonym_name, and it used to nullify type names
902 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
903 type's name as soon as space for that type is allocated.
904 * xcoffread.c: ignore a section's lineno information if it is
905 not `.text'. (In rs6000 bfd portation integration, skipping over
906 `.pad' sections are ignored since it was in machine independent
907 part of the code. Thus, a problem of fake sections with invalid
908 lineno information arised.)
910 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
911 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
912 * rs6000-tdep.c: make function_frame_info() work whether or not
913 reading from a core file.
914 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
916 * infrun.c. main.c, printcmd.c. symtab.c:
917 More changes from IBM for rs6000.
920 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
922 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
923 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
924 Merge in changes (mostly from IBM) for RS6000.
925 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
926 More changes from IBM for RS6000. These are in machine-
927 independent code, and probably could do with some cleaning
928 up. The most questionable of these are #ifdef IBM6000.
929 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
930 to single_step() (for consistency with rs6000 and i860).
931 * utils.c: Allow the 1st arg to xrealloc to be NULL
932 (in which case do malloc). This removes the need for
933 some tests in xcoff code (and perhaps other places?).
934 * coffread.c: Removed variables last_source_file,
935 type_vector, and type_vector_length as these are now
936 defined by buildsym.[ch].
937 * defs.h: Remove prototypes for malloc and realloc, since
938 these should only be used to implement xmalloc and xrealloc,
939 and they conflict with <stdlib.h> in AIX - where they
940 return void* even when __STDC__ isn't defined. Sigh.
941 * munch: Recognize *initialize* in data as well as text
942 (AIX uses data). Also, incorporate a patch from Garrett
943 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
944 much more sensible, by only trying to match the name of
945 the initialize_foo function, and not the junk before it.
947 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
949 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
950 unless symbol table indicates that something has changed.
952 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
954 * remote.c: Make it work for embedded MIPS. Increase buffer
955 size, and use throughout. Round buffer size up if too many regs.
956 Support baud rate setting and try for an 8-bit path. If
957 interrupted while waiting for target, send a ^C down the wire.
958 Avoid single-byte reads.
959 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
961 * mips-xdep.h: Avoid the embedded regs when on Unix.
963 * mipsread.c: Byte-swap the symbol table structures, using
964 routines from ecoff.c, to read a symbol table written in any
965 of the four possible byte orders.
966 * configure.in (mips-big-* target): Same as Sony News.
967 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.
968 * ecoff.c: New file for symbol swapping routines.

973 all-breakpoints' command.
974 * (get_number): Allow users to enter negative breakpoint numbers.
975 * (breakpoint_1): Reformat display of 'info break' to show new
977 * (create_longjmp_breakpoint, breakpoint_re_set,
978 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
979 symfile.c (syms_from_objfile): Re-do
980 insertion of longjmp breakpoints. Move all code into
981 breakpoint_re_set, and call that instead of
982 create_longjmp_breakpoint in symfile.c.
984 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
986 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.
987 * breakpoint.c (breakpoint_re_set): Use ALL_BREAKPOINTS_SAFE.
988 * symtab.c (find_pc_symtab): Handle having no objfiles.

990 * objfiles.c (free_all_objfiles): Add.
991 * symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE): Add.
992 * symfile.c (symbol_file_command): free all objfiles when
993 specifying a new symbol file.
994 (reread_symbols): Stat the file name, don't fstat the descriptor.
996 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
998 * Makefile.in, configure.in: removed traces of namesubdir,
999 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1000 copyrights to '92, changed some from Cygnus to FSF.

1010 * Makefile.in (VERSION): Roll to gdb-4.4.4.
1012 * symfile.c (symbol_file_command): strcmp => !strcmp.
1013 * breakpoint.h: Move prototypes to follow enum definition they need.
1014 * breakpoint.c, infrun.c: Lint.
1015 * printcmd.c: Use `enum enable' rather than `enum
1017 * mipsread.c: First pass at making it compile with the new
1018 objfile changes. Probably seriously broken still, but it
1021 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)

1028 types instead of using magic breakpoint numbers.

1039 * minsyms.c (install_minimal_symbols): Add bunches to any
1040 existing minsyms in the objfile. Avoid extra mallocation
1041 by working directly in the obstack. Remove ignored `mainline' parm.

1043 xcoffread.c: Change all callers.
1044 * FIXME: We should be able to eliminate MAINLINE from all the
1045 symbol readers now, with a small bit of work.
1047 * valops.c, value.h: Lint.
1048 * remote-vx.c: Add missing break; statement. Bugfix by

1414 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
1415 Remove to_call_function and target_call_function, since it
1416 always calls the same thing (call_function_by_hand).
1417 * core.c, exec.c, solib.c: Rename target_ops sections =>
1419 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,
1420 target.h: target_kill takes no args.
1421 * language.c (language_info): Scaffolding to allow briefer
1422 messages when the current language changes. FIXME.
1423 * xm-amix.h, xm-i386v4.h, xm-stratus.h: Define NORETURN to avoid
1424 complaints about volatile functions.
1425 * xm-sysv4.h (HAVE_MMAP): Define.
1427 Thu Feb 20 09:04:18 1992 Fred Fish (fnf at cygnus.com)

1436 * m2-exp.y: Remove unused CONST; Rename OR and AND.
1437 * utils.c: Avoid declaring malloc and realloc. Lint.

1440 Mon Feb 17 07:13:27 1992 Fred Fish (fnf at cygnus.com)
1442 * dwarfread.c (process_dies): Add case to handle TAG_pointer_type
1443 DIE's. Add new function read_tag_pointer_type() to read them.
1445 * dwarfread.c (dwarf_read_array_type, read_subroutine_type):
1446 When creating a new user defined type, check to see if a partial
1447 type already exists, and if so, bash it to fit.
1449 Fri Feb 14 19:00:17 1992 John Gilmore (gnu at cygnus.com)
1451 * coffread.c (decode_base_type): Pass long, not union.

1470 number for double pseudo-registers.
1472 Fri Feb 7 07:56:05 1992 John Gilmore (gnu at cygnus.com)
1474 * buildsym.c (read_struct_type): Avoid double-bump of parse ptr

1476 <mccanne@horse.ee.lbl.gov>.
1478 * exec.c (set_section_name): Pass arg to exec_files_info;
1479 only call it if interactive. From Francis Kauth <fk@tv.tv.tek.com>.
1481 Thu Feb 6 17:41:32 1992 John Gilmore (gnu at cygnus.com)
1483 * main.c (print_gdb_version): Copyright msg: only this year.
1484 (cd_command): Avoid changing current_directory on error.
1486 Thu Feb 6 15:14:01 1992 Per Bothner (bothner at cygnus.com)
1488 * mipsread.c (parse_partial_symbols): Handle dependencies
1489 between partial symbol tables (when not doing stabs-in-ecoff).
1490 (This used to be handled by parse_fdr, but parse_fdr was
1491 incompatible with handling stabs-in-ecoff, so the code
1492 was re-written to not use parse_fdr. Unfortunately,
1493 the logic to handle dependencies was overlooked.)
1495 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
1497 * coffread.c (read_enum_type): Use the size of a target int when
1499 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
1501 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
1502 * symtab.c (lookup_reference_type, lookup_ptr_type): use
1503 TARGET_PTR_BIT to determine size of a pointer
1504 * values.c (unpack_long): when unpacking a REF or a PTR don't
1505 assume the size of the type.
1507 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
1509 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
1510 looking at its members. Improve guess between struct and union,
1511 only assuming union if multiple members have offsets of zero.
1513 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
1515 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
1516 (This is just for clarity - and one day permitting us to
1517 change FP0_REGNUM from 38 to 32, which would make more sense.)
1518 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
1519 register numbers in stabs-in-ecoff get handled correctly.
1521 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
1523 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,
1524 config/mh-vaxbsd, configure.in: Split up config stuff for Vaxen
1525 into BSD and Ultrix.
1527 Sat Feb 1 04:39:41 1992 John Gilmore (gnu at cygnus.com)
1529 * dbxread.c (dbx_symfile_init): Call malloc, not xmalloc.
1531 Sat Feb 1 04:15:41 1992 Stu Grossman (grossman at cygnus.com)
1533 * Makefile.in: Increment version to 4.4.1.
1534 * main.c (print_gdb_version): Update copyright notice.
1536 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
1538 * mipsread.c: Prepend "struct " to the names of structure
1539 types, and similarly for enums and unions. (This used
1540 to be done, but got lost in the re-write to "guess" the
1541 difference between enum/struct/union.)
1542 Also, guess that a tag is an enum if the first member
1545 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
1547 * xm-vax.h: #ifndef ultrix around #include of endian.h and
1550 Fri Jan 31 00:05:01 1992 John Gilmore (gnu at cygnus.com)
1552 * Projects: Patching executables is done.
1553 * Makefile.in (VERSION): Roll to gdb-4.4.
1554 * README, WHATS.NEW: Update for gdb-4.4.
1556 * symfile.c (reread_symbols): Whenever we reread one object
1557 file's symbols, we must restart the scan, because the object_files
1558 chain has been permuted.
1560 * exec.c (exec_files_info): Split out into print_section_info.
1561 Print BFD filename of each section if it's not the default one.
1562 * core.c (core_files_info): Call print_section_info.
1564 * xm-vax.h: Include a few system header files whose definitions
1565 must precede defs.h.
1566 * language.c, language.h: Make some things const.
1567 * expression.h, main.c: const spreads like ooze.
1569 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
1570 since BREAKPOINT values can be >0x80.
1572 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
1574 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
1576 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
1578 * sparc-pinsn.c: Remove kludge for preferring architectures.
1579 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
1580 and forever. Add `add' instruction to the set that get checked
1581 for a preceding `sethi' in order to print an absolute address.
1582 Corresponding changes in ../include/opcode/sparc.h needed
1583 to eliminate garbage instructions.
1585 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
1587 * mipsread.c (parse_partial_symbols): Make sure partial
1588 symbols are created for external symbols (as used to be
1589 the case). This is a bit of a pain with the mips-coff.
1590 It uses a table which points to all of the external
1591 symbols belonging to a particular FDR or psymtab.
1592 Once we've generated this table, we might as well save
1593 it, and then use it in psymtab_to_symtab_1 to find
1594 the symbols to pass to parse_external().
1595 * symfile.c, symfile.c: New function start_psymtab_common
1596 to share the common parts of allocating a new psymtab
1597 for dbxread, mipsread (and later dwarfread). Its code
1598 was pulled out from start_psymtab in dbxread.c.
1599 * dbxread.c (start_psymtab): Use start_psymtab_common().
1601 * valprint.c (val_print): If there is an error when trying
1602 to print a string, check to see if there really is a problem
1603 by reading just one character. If that works, assume
1606 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
1608 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
1609 cypress, v8 mnemonics in that order.
1611 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
1613 * sparc-pinsn.c: Put the qsort() back in.
1615 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
1617 * findvar.c (read_register, write_register): Handle machines
1618 where REGISTER_TYPE is not the same size as "int".
1620 Handle debug symbols in dynamically loaded (relocated) code:
1622 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
1623 offset to process_one_symbol.
1624 (process_one_symbol): Take new offset parameter. Add it into
1625 appropriate symbol types to relocate symbols to loaded addresses.
1626 Handle all possible symbol types, and complain() about types that
1627 we don't expect to see.
1628 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
1629 process_one_symbol (FIXME, should pass real offset).
1633 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
1635 (set_breakpoint, break_command_1, until_break_command,
1636 catch_command_1, breakpoint_re_set_one): Use it.
1637 * symtab.h (resolve_sal_pc): Declare.
1638 * infcmd.c (jump_command): Use resolve_sal_pc.
1640 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
1642 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
1644 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
1646 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
1647 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
1648 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
1650 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
1652 * dbxread.c (process_one_symbol): Make a first cut at handling
1653 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
1655 * symtab.c (find_pc_line): Fix stepping into and out of #included
1658 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
1660 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
1661 no longer any need to copy ../include/opcode/* into gdb.
1663 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
1665 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
1667 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
1669 * valprint.c (type_print_base, type_print_method_args):
1670 Print C++ constructor methods without bogus "return type."
1672 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
1674 * infptrace.c (child_xfer_memory): Parameter "target" should
1675 be a pointer to a structure, not the entire structure.
1677 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
1679 * depend: Convert the couple of references to ansidecl.h that
1680 used the local gdb version to use the ../include version.
1682 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
1685 (child_xfer_memory): Takes pointer to a struct, not entire struct.
1686 (inferior_proc_init): Fix non-ANSI version of args.
1687 (attach): Call print_sys_errmsg with correct number of args.

1719 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
1720 New files for stratus. Not complete enough to actually build
1721 on the Stratus machine; that awaits copyright assignment for
1724 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
1725 for getting custom flags into CFLAGS when doing makes.
1727 * configure.in: Add config information for stratus.

1754 nexting over recursive function calls.
1756 * target.c (target_read_string): Create this routine to read null
1757 terminated strings from the target. It deals with running off the
1758 end of memory elegantly as well. solib.c (find_solib): Use
1759 target_read_string() to avoid problems with running off the end of
1762 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
1763 that reference pgrp_inferior.
1765 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)

1779 freescope, buildblock closescope, record_line, add_symbol_to_list,
1780 gatherblocks, make_blockvector): Extensive changes to switch
1781 to generic symbol table building code in buildsym.c. Remove
1782 scope tree structures and functions, symbol table building
1783 functions, and lots of other small changes.
1785 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove

1806 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
1807 to reflect actual locations of opcode files, so TAGS target will
1810 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
1812 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
1815 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
1816 dereferencing to access the correct elements.
