1352 Wed Mar 25 14:55:48 1992 Per Bothner (bothner@cygnus.com)
1354 * command.c, main.c (various places): Use ctype.h macros
1355 (such as isupper(x)), instead of hard-wiring in ASCII-isms
1356 (such as (x >= 'A' && x <= 'Z')).
1357 (There are still more of these in other files.)
1358 * main.c (defined_command): Lower-case the user's
1359 new command before entering it. Needed because
1360 command lookup is case-insensitive (and also lower-cases).
1361 (Based on Metin's earlier patch.)
1363 Tue Mar 24 23:27:01 1992 K. Richard Pixley (rich@cygnus.com)
1365 * config/irix4.mh: new file.

1382 flags to disable use of GNU malloc/mmalloc.
1383 * munch: Change SYSV rule to allow .text before the label,
1384 as well as after, to work for AIX.
1385 * gdbtypes.h: Minor clarifiction.
1387 Tue Mar 24 07:26:19 1992 Michael Tiemann (tiemann@cygnus.com)
1389 * buildsym.c (read_struct_type): Handle cretinous dbx symbol name
1390 continuation in yet another place (between method declarations).
1392 Mon Mar 23 23:01:41 1992 Stu Grossman (grossman at cygnus.com)
1394 * mips-tdep.c: include symfile.h and objfiles.h to fix
1397 Mon Mar 23 15:49:14 1992 Per Bothner (bothner@cygnus.com)
1399 * valops.c (value_struct_elt_for_reference): Added 'offset'
1400 parameter to handle multiple inheritance.
1401 * eval.c, value.h: Update accordingly.

1457 * partial-stab.h: Use new per-objfile entry info.
1458 * symfile.h (struct objfile): Removed, moved to objfiles.h.

1467 Thu Mar 19 18:49:45 1992 Per Bothner (bothner@cygnus.com)
1469 More C++ improvements (pointers to members, qualified names).
1470 * c-exp.y: Support exp.type::name and exp->type::name
1471 syntaxes. (Unfortunately, doesn't work for static members.)
1472 * c-exp.y, eval.c: Make type::~type work better.
1473 * eval.c (evaluate_subexp: OP_SCOPE): Replace use of
1474 value_static_field by value_struct_elt_for_reference.
1475 * eval.c (evaluate_subexp): Merge code for STRUCTOP_MEMBER
1476 and STRUCTOP_MPTR; cast arg1 to domain-type of arg2.
1477 * eval.c (evaluate_subexp): Remove special case for UNOP_ADDR
1478 for OP_SCOPE operand; no point in it now that we use lazy
1479 reading of values, and use "reference to member" objects.
1480 * gdbtypes.h: Clarify comment.
1481 * valops.c: Change value_struct_elt_for_address to return
1482 a reference (or variable), rather than a pointer. Change
1483 the name to value_struct_elt_for_reference to reflect this.
1484 Returning a reference instead of a address provides a
1485 generalization, since we can use the routine for both
1486 class::name as well as &class::name.
1487 Also, recurse to handle multiple inheritance properly.
1488 * valprint.c: Moved code to print pointer-to-members
1489 to new function point_class_member. This allows a
1490 "reference-to-member" to be printed using the same code.

1494 version of value_static_field (which can then be deleted).
1495 * value.h: Rename value_struct_elt_for_address to
1496 value_struct_elt_for_reference. Delete value_static_field.
1497 * values.c: Remove no longer used function value_static_field.

1506 elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
1507 Pass pointer to struct objfile rather than pointer to sym_fns.
1508 Change references inside each function accordingly. Allocate any
1509 symbol file specific info in the per-objfile memory region.
1510 * dbxread.c (free_and_init_header_files): Break function into
1511 free_header_files(), called from dbx_symfile_finish(), and
1512 init_header_files(), called from dbx_new_init().
1513 * dbxread.c (dbx_new_init): Move deallocation things to new
1514 dbx_symfile_finish function.
1515 * elfread.c (elf_new_init): Call buildsym_new_init().

1517 routine for the objfile before deallocating other stuff.
1518 * sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
1519 * symfile.h: Move struct sym_fns to before struct objfile def.
1520 Add sym_finish function pointer and change prototypes of other
1521 function pointers to reflect passing struct objfile pointer rather
1522 than struct sym_fns pointer.
1523 * symfile.c: Remove now obsolete symtab_fns pointer.
1524 * symfile.c (symfile_init): Renamed to find_sym_fns, and now only
1525 locates the correct sym_fns struct for the given objfile.
1526 * symfile.c (syms_from_objfile, symbol_file_add): Restructured
1527 for better support of mapped symbol tables.
1528 * symfile.c (symbol_file_command): Remove obsolete code using
1530 * symfile.h: Remove duplicate declarations for symfile_objfile,
1531 entry_point, and object_files.
1532 * target.c (target_info): Compare symfile_objfile to NULL.
1533 * xcoffread.c (aixcoff_new_init): Move deallocation stuff to
1534 aixcoff_symfile_finish().

1548 * values.c (value_static_field): Allow evaluation of
1549 CLASS::METHOD, returning a function pointer.

1747 * config.sub configure.in config/.Sanitize config/mh-irix4
1748 gdb/.Sanitize gdb/configure.in gdb/mips-tdep.c gdb/mipsread.c
1749 gdb/procfs.c gdb/signame.h gdb/tm-irix3.h gdb/tm-mips.h
1750 gdb/xm-irix4.h gdb/config/.Sanitize gdb/config/mt-irix3
1751 gdb/config/mh-irix4 texinfo/configure.in: Port to SGI Irix-4.x.
1753 Wed Mar 4 11:56:42 1992 Fred Fish (fnf@cygnus.com)
1755 * defs.h, utils.c: xrealloc takes PTR as first arg.
1756 * defs.h: Reword confusing comment about ANSI prototypes.
1757 * defs.h: Some minor whitespace changes.
1758 * infrun.c (wait_for_inferior): Compare int tmp to int 0,
1759 not NULL, which can be (void *).
1760 * tm-amix.h, tm-i386v4.h: Add defines for setjmp/longjmp handling.
1761 * tm-i386v.h (SP_ARG0): Define
1762 * xm-sysv4.h: Back out of change for missing prototypes.
1763 * i386-tdep.c (get_longjmp_target): Add function.
1765 Wed Mar 4 05:46:11 1992 K. Richard Pixley (rich@rtl.cygnus.com)
1767 * Makefile.in: install man page too.
1769 Tue Mar 3 15:11:52 1992 Michael Tiemann (tiemann@cygnus.com)
1771 * All GDB files that #include defs.h: Removed stdio.h.
1772 (defs.h): #include stdio.h.
1774 Mon Mar 2 23:00:12 1992 Steve Chamberlain (sac@thepub.cygnus.com)
1776 * gdbtypes.c (lookup_pointer_type): initialize the TYPE_LENGTH of
1777 a ptype to reflect the setting of TARGET_PTR_BIT. Set the
1778 TYPE_FLAGS of a ptype to TYPE_FLAG_UNSIGNED.
1779 * tm-h8300.h, h8300-tdep.c, remote-hms.c: personal checkpoint
1780 * printcmd.c (print_address): if ADDR_BITS_REMOVE is defined, use
1781 it before printing out the hex shape of an address.
1783 Sun Mar 1 17:41:09 1992 Per Bothner (bothner@cygnus.com)
1785 * rs6000-xdep.c (frame_initial_stack_address): Move
1786 code to set frame->cache_fsr into new separate function
1787 frame_get_cacahe_fsr. This allows fixing a fatal error.
1788 * xcoffexec.c: Turn previously suppressed error
1789 message back on, after cleaning up BFD.
1791 * breakpoint.c (breakpoint_re_set): Removed (at least for now)
1792 printing of blank line, since it cases printing of an
1793 extra blank line. Is this intended? It does mess up
1795 * defs.h: Put back declarations of malloc and realloc,
1796 but protected by #ifndef MALLOC_INCOMPATIBLE.
1797 * objfiles.c: Undo previous change: Use malloc/realloc
1798 for objfile malloc/realloc fields (but add a cast).
1799 * xcoffexec.c: Suppress an error message (for now).
1801 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
1803 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1804 [Mail dated Fri, 21 Feb 92 13:14:54 -0800]
1805 * buildsym.c: Use smash_to_pointer_type() to handle forward type
1807 * xcoffread.c: Modifications to C_DECL storage class handling, and
1808 introduction of an old smash_to_pointer_type() routine.
1810 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1811 [Mail dated Thu, 20 Feb 92 13:57:16 -0800]
1812 * rs6000-xdep.c, rs6000-tdep.c, tm-rs6000.h: function_frame_info()
1813 parameters have been modified.
1815 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1816 [Mail dated Thu, 20 Feb 92 10:10:05 -0800]
1817 * rs6000-tdep.c: Before Feb 5 92, register_valid[] array was not used,
1818 and fetch_inferior_registers() always fetched all the registers
1819 resulting valid register values at hand all the time. Pushing a dummy
1820 frame did not require validating all register values first. After
1821 putting the above mechanism into action, we didn't have valid registers
1822 values always ready. Thus, all registers need to be fetched before
1823 pushing a dummy frame now.
1825 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1826 [Mail dated Thu, 13 Feb 92 16:22:44 -0800]
1827 * rs6000-xdep.c: frame_initial_stack_address() function to calculate
1828 the starting address (actual frame address) of a frame.
1829 * rs6000-tdep.c: modifications to function_frame_info() to see if
1830 function reserves a frame pointer register (alloca register)
1831 * tm-rs6000.h: EXTRA_FRAME_INFO, FRAME_ARGS_ADDRESS and
1832 FRAME_LOCALS_ADDRESS has been updated to support debugging of
1833 functions with alloca() calls.
1835 Sun Mar 1 13:13:39 1992 Fred Fish (fnf@cygnus.com)
1837 * xm-sysv4.h: Provide definitions/prototypes for host environment
1838 functions for which no definitions or prototypes are provided in
1839 any currently included gdb or host environment header files.
1840 For SVR4, this currently includes malloc and realloc, which cannot
1841 be portably prototyped in any gdb include file.
1843 Sat Feb 29 14:43:02 1992 Per Bothner (bothner@cygnus.com)
1845 * buildsym.h: Remove obsolete variable file_stabs.
1847 * Makefile.in: Move place where configure merges in host-
1848 and target-dependent fragments later, so the latter
1849 can override (say) GNU_MALLOC.
1850 * config/mh-rs6000: Use system malloc. Otherwise, I
1851 ended up with *two* incompatible versions of malloc
1852 (functions in libc would call the malloc in libc).
1853 I assume this is a shared library problem.
1855 * remote.c: Fix (presumed) typo.
1856 * objfiles.c: Use xmalloc/xrealloc instead of
1857 malloc/realloc (since the latter are no longer declared).
1859 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1860 [Mail dated Thu, 6 Feb 1992 10:22:02 -0800]
1861 * rs6000-xdep.c: Improvements to fetch_inferior_registers() to
1862 handle individual registers.
1863 * tm-rs6000.h: Fix SAVED_PC_AFTER_CALL macro to handle pc value
1864 correctly in case it wasn't cached yet. (A problem showed up
1865 after fetching individual registers.)
1866 * buildsym.c: Disable type_synonym_name's type name overwriting
1867 in cases it is unnecesary. rs6000 portation doesn't use
1868 type_synonym_name, and it used to nullify type names
1869 * xcoffread.c: to handle g++'s typename abbreviation, fill in a
1870 type's name as soon as space for that type is allocated.
1871 * xcoffread.c: ignore a section's lineno information if it is
1872 not `.text'. (In rs6000 bfd portation integration, skipping over
1873 `.pad' sections are ignored since it was in machine independent
1874 part of the code. Thus, a problem of fake sections with invalid
1875 lineno information arised.)
1877 Changes from metin@ibmpa.awdpa.ibm.com (Metin G. Ozisik)
1878 [Mail dated Thu, 6 Feb 1992 13:26:22 -0800]
1879 * rs6000-tdep.c: make function_frame_info() work whether or not
1880 reading from a core file.
1881 * tm-rs6000.h: Implementation of FRAME_FIND_SAVED_REGS macro.
1883 * infrun.c. main.c, printcmd.c. symtab.c:
1884 More changes from IBM for rs6000.
1887 Thu Feb 27 22:57:19 1992 Per Bothner (bothner@cygnus.com)
1889 * rs6k-opcode.h, tm-rs6000.h, xm-rs6000.h, rs6000-tdep.c,
1890 rs6000-xdep.c, xcoffexec.c, xcoffread.c:
1891 Merge in changes (mostly from IBM) for RS6000.
1892 * breakpoint.c, buildsym.c, infptrace.c, stack.c, symtab.c:
1893 More changes from IBM for RS6000. These are in machine-
1894 independent code, and probably could do with some cleaning
1895 up. The most questionable of these are #ifdef IBM6000.
1896 * infrun.c, sparc-tdep.c: Pass a parameter (signal number)
1897 to single_step() (for consistency with rs6000 and i860).
1898 * utils.c: Allow the 1st arg to xrealloc to be NULL
1899 (in which case do malloc). This removes the need for
1900 some tests in xcoff code (and perhaps other places?).
1901 * coffread.c: Removed variables last_source_file,
1902 type_vector, and type_vector_length as these are now
1903 defined by buildsym.[ch].
1904 * defs.h: Remove prototypes for malloc and realloc, since
1905 these should only be used to implement xmalloc and xrealloc,
1906 and they conflict with <stdlib.h> in AIX - where they
1907 return void* even when __STDC__ isn't defined. Sigh.
1908 * munch: Recognize *initialize* in data as well as text
1909 (AIX uses data). Also, incorporate a patch from Garrett
1910 Wollman <wollman@uvm-gen.uvm.edu> to make the sed script
1911 much more sensible, by only trying to match the name of
1912 the initialize_foo function, and not the junk before it.
1914 Thu Feb 27 20:07:43 1992 Stu Grossman (grossman at cygnus.com)
1916 * breakpoint.c (breakpoint_re_set_one): Don't reset breakpoint
1917 unless symbol table indicates that something has changed.
1919 Thu Feb 27 11:48:47 1992 John Gilmore (gnu at cygnus.com)
1921 * remote.c: Make it work for embedded MIPS. Increase buffer
1922 size, and use throughout. Round buffer size up if too many regs.
1923 Support baud rate setting and try for an 8-bit path. If
1924 interrupted while waiting for target, send a ^C down the wire.
1925 Avoid single-byte reads.
1926 * tm-mips.h: Add more embedded-system registers to REGISTER_NAMES
1928 * mips-xdep.h: Avoid the embedded regs when on Unix.
1930 * mipsread.c: Byte-swap the symbol table structures, using
1931 routines from ecoff.c, to read a symbol table written in any
1932 of the four possible byte orders.
1933 * configure.in (mips-big-* target): Same as Sony News.
1934 * config/mt-bigmips, config/mt-littlemips: Add ecoff.o.
1935 * ecoff.c: New file for symbol swapping routines.
1937 Thu Feb 27 09:26:38 1992 Stu Grossman (grossman at cygnus.com)
1939 * breakpoint.c (all_breakpoints_info, breakpoint_1): Add 'info
1940 all-breakpoints' command.
1941 * (get_number): Allow users to enter negative breakpoint numbers.
1942 * (breakpoint_1): Reformat display of 'info break' to show new
1944 * (create_longjmp_breakpoint, breakpoint_re_set,
1945 breakpoint_re_set_one, enable/disable_longjmp_breakpoint),
1946 symfile.c (syms_from_objfile): Re-do
1947 insertion of longjmp breakpoints. Move all code into
1948 breakpoint_re_set, and call that instead of
1949 create_longjmp_breakpoint in symfile.c.
1951 Thu Feb 27 06:11:05 1992 John Gilmore (gnu at cygnus.com)
1953 * breakpoint.h (ALL_BREAKPOINTS_SAFE): Add.
1954 * breakpoint.c (breakpoint_re_set): Use ALL_BREAKPOINTS_SAFE.
1955 * symtab.c (find_pc_symtab): Handle having no objfiles.
1956 * infcmd.c: Fix comment.
1957 * objfiles.c (free_all_objfiles): Add.
1958 * symfile.h (ALL_OBJFILES, ALL_OBJFILES_SAFE): Add.
1959 * symfile.c (symbol_file_command): free all objfiles when
1960 specifying a new symbol file.
1961 (reread_symbols): Stat the file name, don't fstat the descriptor.
1963 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
1965 * Makefile.in, configure.in: removed traces of namesubdir,
1966 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
1967 copyrights to '92, changed some from Cygnus to FSF.
1969 Tue Feb 25 19:31:19 1992 Stu Grossman (grossman at cygnus.com)
1971 * dbxread.c (end_psymtab): Delete empty psymtabs.
1972 * symfile.c (allocate_psymtab): Recycle empty psymtabs.
1973 * symfile.h (struct objfile): Add free_psymtabs.
1975 Sat Feb 22 02:00:32 1992 John Gilmore (gnu at cygnus.com)
1977 * Makefile.in (VERSION): Roll to gdb-4.4.4.
1979 * symfile.c (symbol_file_command): strcmp => !strcmp.
1980 * breakpoint.h: Move prototypes to follow enum definition they need.
1981 * breakpoint.c, infrun.c: Lint.
1982 * printcmd.c: Use `enum enable' rather than `enum
1984 * mipsread.c: First pass at making it compile with the new
1985 objfile changes. Probably seriously broken still, but it
1988 Sat Feb 22 00:56:39 1992 Stu Grossman (grossman at cygnus.com)
1990 * infrun.c, infcmd.c, breakpoint.c, main.c, symfile.c,

1992 mips-tdep.h, tm-sun3.h, tm-68k.h, m68k-tdep.h: Add support for
1993 stepping (and nexting) through longjmp(). Also, cleanup
1994 breakpoint handling quite a bit by creating explicit breakpoint
1995 types instead of using magic breakpoint numbers.
1996 Makefile.in: Update version to 4.4.3
1998 Sat Feb 22 00:08:50 1992 John Gilmore (gnu at cygnus.com)
2000 * buildsym.c, dwarfread.c, gdbtypes.c, inflow.c, main.c,
2001 minsyms.c, printcmd.c, remote.c, saber.suppress: Saberlint.
2002 * symmisc.c, xcoffread.c: Move debug functions to symmisc.c.
2004 * xm-sun3os4.h, xm-sun4os4.h: Enable HAVE_MMAP.
2006 * minsyms.c (install_minimal_symbols): Add bunches to any
2007 existing minsyms in the objfile. Avoid extra mallocation
2008 by working directly in the obstack. Remove ignored `mainline' parm.
2009 * coffread.c, dbxread.c, elfread.c, mipsread.c, solib.c, symtab.h,
2010 xcoffread.c: Change all callers.
2011 * FIXME: We should be able to eliminate MAINLINE from all the
2012 symbol readers now, with a small bit of work.
2014 * valops.c, value.h: Lint.
2015 * remote-vx.c: Add missing break; statement. Bugfix by
2016 Michael Sclafani, <sclafani@src.dec.com>.

2381 target.c, target.h, valarith.c, valops.c, value.h, xcoffexec.c:
2382 Remove to_call_function and target_call_function, since it
2383 always calls the same thing (call_function_by_hand).
2384 * core.c, exec.c, solib.c: Rename target_ops sections =>
2386 * infcmd.c, inflow.c, infptrace.c, infrun.c, main.c, target.c,

2418 * coffread.c (decode_base_type): Pass long, not union.

2455 * mipsread.c (parse_partial_symbols): Handle dependencies
2456 between partial symbol tables (when not doing stabs-in-ecoff).
2457 (This used to be handled by parse_fdr, but parse_fdr was
2458 incompatible with handling stabs-in-ecoff, so the code
2459 was re-written to not use parse_fdr. Unfortunately,
2460 the logic to handle dependencies was overlooked.)
2462 Thu Feb 6 11:51:39 1992 Steve Chamberlain (sac at rtl.cygnus.com)
2464 * coffread.c (read_enum_type): Use the size of a target int when
2466 * defs.h: added new #define for TARGET_PTR_BIT, defaults to size
2468 * h8300-tdep.c, remote-hms.c, tm-h8300.h: too many changes to count
2469 * symtab.c (lookup_reference_type, lookup_ptr_type): use
2470 TARGET_PTR_BIT to determine size of a pointer
2471 * values.c (unpack_long): when unpacking a REF or a PTR don't

2474 Wed Feb 5 22:29:59 1992 John Gilmore (gnu at cygnus.com)
2476 * mipsread.c (parse_symbol): Avoid clobbering enum pointer when
2477 looking at its members. Improve guess between struct and union,
2478 only assuming union if multiple members have offsets of zero.
2480 Tue Feb 4 18:05:44 1992 Per Bothner (bothner at cygnus.com)
2482 * mipsread.c: Use (FP0_REGNUM-32) instead of magic number 6.
2483 (This is just for clarity - and one day permitting us to
2484 change FP0_REGNUM from 38 to 32, which would make more sense.)
2485 * tm-mips.h: Added STAB_REG_TO_REGNUM macro, so that
2486 register numbers in stabs-in-ecoff get handled correctly.
2488 Sat Feb 1 04:45:10 1992 Stu Grossman (grossman at cygnus.com)
2490 * xm-vax.h, xm-vaxult.h, xm-vaxbsd.h, config/mh-vaxult,

2501 * main.c (print_gdb_version): Update copyright notice.
2503 Sat Feb 1 01:43:11 1992 Per Bothner (bothner at cygnus.com)
2505 * mipsread.c: Prepend "struct " to the names of structure
2506 types, and similarly for enums and unions. (This used
2507 to be done, but got lost in the re-write to "guess" the
2508 difference between enum/struct/union.)
2509 Also, guess that a tag is an enum if the first member
2512 Fri Jan 31 21:45:51 1992 Stu Grossman (grossman at cygnus.com)
2514 * xm-vax.h: #ifndef ultrix around #include of endian.h and

2521 * README, WHATS.NEW: Update for gdb-4.4.
2523 * symfile.c (reread_symbols): Whenever we reread one object
2524 file's symbols, we must restart the scan, because the object_files
2525 chain has been permuted.
2527 * exec.c (exec_files_info): Split out into print_section_info.
2528 Print BFD filename of each section if it's not the default one.

2531 * xm-vax.h: Include a few system header files whose definitions
2532 must precede defs.h.
2533 * language.c, language.h: Make some things const.
2534 * expression.h, main.c: const spreads like ooze.
2536 * mem-break.c (break_insn, break_insn_size): Use unsigned chars,
2537 since BREAKPOINT values can be >0x80.
2539 Thu Jan 30 17:21:14 1992 Stu Grossman (grossman at cygnus.com)
2541 * infrun.c, xm-i386sco.h: SCO needs to use setpgid().
2543 Thu Jan 30 01:04:23 1992 John Gilmore (gnu at cygnus.com)
2545 * sparc-pinsn.c: Remove kludge for preferring architectures.
2546 Remove #ifdef's for SORT_NEEDED. We need to sort the table, now
2547 and forever. Add `add' instruction to the set that get checked
2548 for a preceding `sethi' in order to print an absolute address.
2549 Corresponding changes in ../include/opcode/sparc.h needed
2550 to eliminate garbage instructions.
2552 Wed Jan 29 19:24:34 1992 Per Bothner (bothner at cygnus.com)
2554 * mipsread.c (parse_partial_symbols): Make sure partial
2555 symbols are created for external symbols (as used to be
2556 the case). This is a bit of a pain with the mips-coff.
2557 It uses a table which points to all of the external
2558 symbols belonging to a particular FDR or psymtab.
2559 Once we've generated this table, we might as well save
2560 it, and then use it in psymtab_to_symtab_1 to find
2561 the symbols to pass to parse_external().
2562 * symfile.c, symfile.c: New function start_psymtab_common
2563 to share the common parts of allocating a new psymtab
2564 for dbxread, mipsread (and later dwarfread). Its code
2565 was pulled out from start_psymtab in dbxread.c.
2566 * dbxread.c (start_psymtab): Use start_psymtab_common().
2568 * valprint.c (val_print): If there is an error when trying
2569 to print a string, check to see if there really is a problem
2570 by reading just one character. If that works, assume
2573 Wed Jan 29 18:58:43 1992 Stu Grossman (grossman at cygnus.com)
2575 * sparc-pinsn.c (compare_opcodes): Make it prefer v6, v7,
2576 cypress, v8 mnemonics in that order.
2578 Tue Jan 28 17:32:13 1992 Per Bothner (bothner at cygnus.com)
2580 * sparc-pinsn.c: Put the qsort() back in.
2582 Mon Jan 27 18:51:03 1992 John Gilmore (gnu at cygnus.com)
2584 * findvar.c (read_register, write_register): Handle machines
2585 where REGISTER_TYPE is not the same size as "int".
2587 Handle debug symbols in dynamically loaded (relocated) code:
2589 * dbxread.c (read_ofile_symtab): Fix up N_CATCH better. Pass
2590 offset to process_one_symbol.
2591 (process_one_symbol): Take new offset parameter. Add it into
2592 appropriate symbol types to relocate symbols to loaded addresses.
2593 Handle all possible symbol types, and complain() about types that
2594 we don't expect to see.
2595 * mipsread.c (psymtab_to_symtab_1): Pass offset of zero to
2596 process_one_symbol (FIXME, should pass real offset).
2600 * breakpoint.c (resolve_sal_pc): Split out code to resolve a
2602 (set_breakpoint, break_command_1, until_break_command,
2603 catch_command_1, breakpoint_re_set_one): Use it.
2604 * symtab.h (resolve_sal_pc): Declare.
2605 * infcmd.c (jump_command): Use resolve_sal_pc.
2607 * source.c (list_command): Shorten "FILE, line N" to "FILE:N".
2609 * putenv.c (putenv): Avoid unportably casting pointers to unsigneds.
2611 * c-exp.y (yylex): `this' and `template' are only tokens in C++.
2613 * xm-convex.h, xm-hp300bsd.h, xm-isi.h, xm-merlin.h, xm-news.h,
2614 xm-np1.h, xm-pn.h, xm-pyr.h, xm-rtbsd.h, xm-symmetry.h, xm-umax.h:
2615 Remove MISSING_VPRINTF declaration, and superfluous "kgdb" defines.
2617 Mon Jan 27 15:46:21 1992 Stu Grossman (grossman at cygnus.com)
2619 * dbxread.c (process_one_symbol): Make a first cut at handling
2620 symbol tables generated by Sun's acc. (#ifdef'd out, FIXME.)
2622 * symtab.c (find_pc_line): Fix stepping into and out of #included
2625 Mon Jan 27 13:00:55 1992 Stu Grossman (grossman at cygnus.com)
2627 * Makefile.in (OPCODES): Remove OPCODES defs and refs. There is
2628 no longer any need to copy ../include/opcode/* into gdb.
2630 Mon Jan 27 12:30:38 1992 John Gilmore (gnu at cygnus.com)
2632 * ChangeLog, ChangeLog-9091: Split ChangeLog at 1992.
2634 Sun Jan 26 19:05:40 1992 Per Bothner (bothner at cygnus.com)
2636 * valprint.c (type_print_base, type_print_method_args):
2637 Print C++ constructor methods without bogus "return type."
2639 Sat Jan 25 15:57:59 1992 Fred Fish (fnf at cygnus.com)
2641 * infptrace.c (child_xfer_memory): Parameter "target" should
2642 be a pointer to a structure, not the entire structure.
2644 Fri Jan 24 01:30:27 1992 Fred Fish (fnf at cygnus.com)
2646 * depend: Convert the couple of references to ansidecl.h that
2647 used the local gdb version to use the ../include version.
2649 Thu Jan 23 22:24:43 1992 Fred Fish (fnf at cygnus.com)
2652 (child_xfer_memory): Takes pointer to a struct, not entire struct.
2653 (inferior_proc_init): Fix non-ANSI version of args.
2654 (attach): Call print_sys_errmsg with correct number of args.
2655 (mappingflags): Make static, does not need to be global.
2657 * i386-tdep.c (i386_frame_num_args): Takes a pointer to a struct
2658 not the entire struct itself.
2660 * valops.c (value_assign): Cast some args to modify_field() and
2661 {read,write}_register_bytes() correctly.
2663 * ansidecl.h: Removed, is duplicate of ../include/ansidecl.h
2665 * Makefile.in (MALLOCSRC): Removed reference to removed local
2668 * dwarfread.c (list_in_scope): Needs an initial value, use file
2671 Mon Jan 20 19:06:28 1992 Stu Grossman (grossman at cygnus.com)
2673 * main.c (main): Make option_index local to keep new getopt happy.
2674 main.c, solib.c, Makefile.in: Update copyright notices.
2676 Mon Jan 20 08:54:00 1992 Michael Tiemann (tiemann at cygnus.com)
2678 * cplus-dem.c (cplus_demangle): Correctly demangle destructors.
2680 Sat Jan 18 17:17:45 1992 Stu Grossman (grossman at cygnus.com)
2682 * Makefile.in (HFILES): Add partial-stab.h.
2684 Sat Jan 18 16:45:01 1992 Fred Fish (fnf at cygnus.com)
2686 * config/mh-stratus, config/mt-stratus, tm-stratus.h, xm-stratus.h:
2687 New files for stratus. Not complete enough to actually build
2688 on the Stratus machine; that awaits copyright assignment for
2691 * Makefile.in (USER_CFLAGS): Add macro specifically reserved
2692 for getting custom flags into CFLAGS when doing makes.
2694 * configure.in: Add config information for stratus.
2696 Thu Jan 16 00:51:46 1992 Fred Fish (fnf at cygnus.com)
2698 * dbxread.c (process_one_symbol): Pass address of structure

2708 * dwarfread.c (locval): Add offreg flag to indicate location
2709 values that are computed off a base register.
2711 * dwarfread.c (new_symbol): Rework TAG_global_variable and
2712 TAG_local_variable cases to account for static variables
2713 within function scopes.
2715 Tue Jan 14 12:28:52 1992 Stu Grossman (grossman at cygnus.com)
2717 * inflow.c: remove #include <sys/dir.h>. Not necessary, and
2718 doesn't exist on some systems.
2720 * infrun.c (wait_for_inferior!!!!): Prevent gdb from hanging when
2721 nexting over recursive function calls.
2723 * target.c (target_read_string): Create this routine to read null
2724 terminated strings from the target. It deals with running off the
2725 end of memory elegantly as well. solib.c (find_solib): Use
2726 target_read_string() to avoid problems with running off the end of
2729 * inflow.c (child_terminal_info): #ifdef TIOCPGRP around lines
2730 that reference pgrp_inferior.
2732 Mon Jan 13 14:57:11 1992 Per Bothner (bothner at cygnus.com)
2734 * tm-mips.h: Removed BLOCK_ADDRESS_ABSOLUTE, now that
2735 mips-tfile has been hacked to act more "traditionally."
2736 * dbxread.c: Fixed typo in comment.
2738 Sun Jan 12 13:08:36 1992 Per Bothner (bothner at cygnus.com)
2740 * mips-tdep.c (mips_skip_prologue): Add some number of
2741 'sw' instructions before 'addiu' adjusts the stack.
2743 Fri Jan 10 13:47:06 1992 Fred Fish (fnf at cygnus.com)
2745 * dwarfread.c (start_symtab, end_symtab, scopecount, openscope,
2746 freescope, buildblock closescope, record_line, add_symbol_to_list,
2747 gatherblocks, make_blockvector): Extensive changes to switch
2748 to generic symbol table building code in buildsym.c. Remove
2749 scope tree structures and functions, symbol table building
2750 functions, and lots of other small changes.
2752 * dwarfread.c: Add new macros GCC_PRODUCER and STREQN. Remove
2753 GCC_COMPILED_FLAG_SYMBOL and GCC2_COMPILED_FLAG_SYMBOL.
2755 Tue Jan 7 13:09:57 1992 Stu Grossman (grossman at cygnus.com)

2772 * Makefile.in: Change tm-svr4.h to tm-sysv4.h. Change xm-svr4.h
2773 to xm-sysv4.h. Split OPCODE_DIR into OPCODE_DIR1 and OPCODE_DIR2
2774 to reflect actual locations of opcode files, so TAGS target will
2777 * i386-tdep.c: Change an erroneous 'm68k' reference to 'i386'.
2779 * i386-tdep.c (supply_fpregset, fill_fpregset): Remove m68k
2782 * m68k-tdep.c (supply_fpregset, fill_fpregset): Fix array
2783 dereferencing to access the correct elements.
