1411 space to the end of the string.
1412 * NEWS: Document this change.
1413 * .gdbinit: Add a space to the "set prompt" command.
1415 Fri Mar 25 12:40:41 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1417 * m3-nat.c, i386m3-nat.c, config/i386/i386m3.mh: Many minor

1420 * buildsym.c (start_subfile, patch_subfile_names), demangle.c
1421 (set_demangling_style, set_demangling_command): Use savestring not

1436 Fri Mar 25 10:14:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1438 * hppa-tdep.c (skip_prologue): Do nothing if not at the beginning
1440 (skip_trampoline_code): Rewrite and add support for argument
1441 relocation stubs stubs, import/export stubs, calls through
1442 "_sr4export" and cascaded trampolines.

1445 if no unwind descriptor is found.
1447 * tm-hppa.h (NUM_REGS): Bump to 128 registers.
1448 (REGISTER_NAMES): Add entries for "right-half" of FP registers.
1449 (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs

1453 (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.
1455 * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
1456 registers as both single and double values (fetching 2nd 32bit half
1457 as necessary). Annotate each register printed with its precision.
1459 * paread.c (read_unwind_info): Fix off-by-one error.

1467 * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
1468 regarding using the PC--using the PC is necessary and all the
1469 FIXME comments in the world won't make it go away.
1471 * valops.c (value_at, value_at_lazy): Give error if we dereference
1473 * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
1474 * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.
1476 * stabsread.c (patch_block_stabs): Add comment about what happens
1477 if the definition is in another compilation unit from the stab.
1479 * dbxread.c (end_psymtab): Add comment about empty psymtabs.

1483 * main.c (complete_command): New command, from Rick Sladkey
1484 <jrs@world.std.com>.
1485 (symbol_completion_function): Don't declare rl_point and
1486 rl_line_buffer; they are now declared in readline.h.
1487 (show_commands): Don't declare history_base; it is declared in
1489 * command.c (lookup_cmd): Don't delete trailing whitespace.
1490 Reverts change of 14 May 1989.
1492 Wed Mar 23 16:14:52 1994 Stu Grossman (grossman at cygnus.com)
1494 * minsyms.c (prim_record_minimal_symbol): Move section deduction
1495 code from prim_record_minimal_symbol_and_info() to here. Callers
1496 of the latter can legitimately supply a section number of -1.
1498 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1500 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
1501 member functions have an element in args for a (nonexistent) this
1504 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1506 * config/pa/tm-hppao.h (NO_PC_SPACE_QUEUE_RESTORE): Define.

1509 queue if NO_PC_SPACE_QUEUE_RESTORE is defined.
1511 * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
1512 for the structure's type. All callers changed.
1514 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
1515 for each structure argument rather than assuming it's either
1516 true or false for all structure arguments.
1518 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
1519 on the length structure passed, not the compiler used.
1521 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
1522 argument for the structure's type.
1524 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1526 * values.c (set_internalvar): Don't set var->value until we are

1535 consistency of psymtabs and symtabs.
1536 * symtab.h (maintenance_check_symtabs): Add prototype.
1537 * maint.c: Add new `maint check-symtabs' command.
1538 * config/i386/tm-i386aix.h, config/i386/tm-sun386.h,
1539 config/i386/tm-symmetry.h (REGISTER_CONVERT_TO_RAW): Fix typo.

1546 * config/i386/symmetry.mt (TDEPFILES): Add i386-tdep.o.
1547 * config/i386/symmetry.mh (NAT_FILE, NATDEPFILES): Add.

1554 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
1556 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
1557 improve remote debugging efficiency. Also fixed problems with
1558 doing function calls for programs with no entry points.
1559 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
1560 entry_point_address.
1561 * inferior.h (PC_IN_CALL_DUMMY): ditto.
1562 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
1563 parse_lines): Pass section_offsets info to these routines so that
1564 we can relocate symbol table entries upon readin.
1565 * (psymtab_to_symtab_1): Set symtab->primary to tell
1566 objfile_relocate to do relocations for our symbols.
1567 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
1568 (which hang off of the symbol table).
1569 * Use prim_record_minimal_symbols_and_info instead of
1570 prim_record_minimal_symbols to supply section info to make minimal
1571 symbol relocations work.
1572 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
1573 -1, try to deduce it from ms_type.
1574 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
1575 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
1576 add code to relocate objfile->sections data structure.
1577 * remote.c (get_offsets): Use new protocol message to acquire
1578 section offsets from the target.
1579 * (remote_wait): Get rid of relocation stuff. That's all handled
1580 by objfile_relocate now.
1581 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
1582 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
1584 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
1586 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
1588 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
1590 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
1591 can no longer set this at run time.
1592 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
1593 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
1594 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
1595 sparc-tdep.c compiles).
1596 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
1598 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1600 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
1601 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
1602 * configure.in: Recognize m68*-cisco*-*.
1604 * Makefile.in (TAGS): Use variables directly, rather than using
1605 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
1606 and means that these filenames no longer need be unique across all
1607 the config/* directories.
1608 * configure.in: Put the config/*/ into TM_FILE, etc.
1610 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
1611 and trapv exceptions.
1613 * target.h (struct section_table), objfiles.h (struct obj_section):
1614 Change name of field sec_ptr to the_bfd_section. More mnemonic
1615 and avoids the (sort of, for the ptx compiler) name clash with
1616 the name of the typedef.
1617 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
1618 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
1620 * utils.c: Include readline.h.
1621 * Makefile.in (utils.o): Add dependency.
1623 * remote.c (getpkt): Add support for run-length encoding.
1625 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1627 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
1629 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1631 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
1632 prim_record_minimal_symbol.
1635 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
1636 computing their offset from the start of the old buffer and adding
1637 to the new buffer, rather than by assuming we can add the
1638 difference between the old buffer and the new buffer (it might not
1639 fit in an int). Merge in cosmetic differences from emacs regex.c
1640 version of this macro.
1642 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1644 * Makefile.in (install-only): Fix use of program_transform_name.

1648 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
1649 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
1650 so I'm nuking the command.
1651 * symtab.c (find_addr_symbol): Comment out, no longer used.
1653 * main.c (main): Don't init_source_path for the -cd argument. Now
1654 that source_path doesn't contain the current_directory from when
1655 GDB started up, init_source_path is no longer useful (and is
1656 harmful because it clobbers a source_path set in $HOME/.gdbinit).
1658 * TODO: Remove item about line numbers being off. It is useless
1659 and confusing without a reproducible test case (it mentions
1660 proceed(), but I was able to step through proceed without trouble).
1662 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1664 For Sunos 4.x targets, enable gdb to set breakpoints in shared
1665 library functions before the executable is run. Retrieve dynamic
1666 symbols from stripped executables.
1667 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
1668 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
1669 symtab.c (list_symbols): Handle mst_solib_trampoline.
1670 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
1671 for all targets, remove IBM6000_TARGET dependencies.
1672 * dbxread.c (read_dbx_dynamic_symtab): New function.
1673 * dbxread.c (dbx_symfile_read): Use it.
1674 * dbxread.c (SET_NAMESTRING): Set namestring to
1675 "<bad string table index>" instead of "foo" if the string index is
1677 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
1679 * symtab.c (list_symbols): Take from_tty as parameter and pass it
1680 to break_command. Handle mst_file_* minimal symbol types.
1681 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
1683 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)
1685 * c-exp.y(yylex): fix potential memory overflow.
1687 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1689 * environ.c (set_in_environ): Eliminate special handling of PATH and
1691 * putenv.c: Removed, conflicts with system declaration of
1692 putenv on RS/6000 running AIX 3.2.5, and above change makes it
1694 * Makefile.in: Change accordingly.
1695 * procfs.c (procfs_create_inferior): Change comment accordingly.
1697 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)
1699 * rs6000-tdep.c: Change value to value_ptr.
1701 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1703 * i386m3-nat.c: Include floatformat.h.
1704 (get_i387_state): Use memset not bzero.
1708 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
1709 ieee-float.h to floatformat.h.
1711 * valprint.c (val_print_string): Ignore error if the error
1712 happened after a terminating '\0'.
1714 * c-valprint.c (c_val_print): Never add 1 to return value from
1715 val_print_string; just return what it returns.
1717 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
1718 looping through all of the enums.
1719 * infrun.c (signals_info): Use it.
1721 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1723 * main.c (main): When printing warning about bad baud rate, don't
1724 use warning(); it relies on current_target which isn't set up yet.
1726 * breakpoint.c (_initialize_breakpoint): Update docstring for
1727 tbreak to match what the code actually does. Don't mention tbreak
1728 in docstrings for "enable once" or "enable breakpoints once".
1730 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1732 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
1733 while (0). That defeats the whole purpose of using do . . . while (0).
1734 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
1735 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
1736 using a ?: expression as an lvalue is not portable.
1738 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
1739 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
1740 'p' and 'r' symbol descriptors into a single symbol to look for a
1742 * README, config/sparc/tm-sparc.h: Update comments.
1744 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1746 * mdebugread.c (parse_type): Do not complain for types with
1747 an `indexNil' aux index, these are simply undefined types.
1748 Remove indexNil check from caller of parse_type.
1749 * mdebugread.c (parse_partial_symbols): Do not enter
1750 stGlobal, scCommon symbols into the minimal symbol table, their
1751 value is the size of the common, not its address.
1752 Handle scInit, scFini, scPData and scXData sections.
1753 Use minimal symbol type mst_file_* for stLabel symbols, instead of
1755 Enter stProc symbols into the global_psymbols list once, not into
1756 the static_psymbols_list.
1757 Get rid of dummy psymtab if it is empty, to allow proper detection
1758 of stripped executables.
1759 * mdebugread.c (cross_ref): Allow cross references to Fortran
1762 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1764 * stabsread.c (common_block_end, fix_common_block): Stash the
1765 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
1766 as to not assume that a pointer fits in an enum.
1768 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
1770 * os9kread.c (fill_sym): check compiler verion number for pre-
1772 * os9kread.c (os9k_process_one_symbol): address of symbol is
1773 relative to section not module.
1774 * stabsread.c (define_symbol): add symbol type 's' as local
1776 * remote-os9k.c: add command 'set monitor_log' to turn on or off
1778 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
1779 * remote-os9k.c: fix bug in 'set remotebaud' function.
1780 * remote-os9k.c (rombug_link): minimize checking so to improve
1782 * symfile.c (symbol_file_command): check if failed to link, also make
1783 the command be able to accept more than one filenames.
1784 * target.c (target_link): check if failed to link with rombug.
1785 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
1787 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1789 * remote-es.c (es1800_child_ops): Don't declare it static.

1797 * dbxread.c: New variable lowest_text_address.
1798 (record_minimal_symbol, read_dbx_symtab): Set it.
1799 (read_dbx_symtab): Use lowest_text_address + text_size instead of
1800 end_of_text_address.
1801 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
1803 * dbxread.c (end_psymtab): Remove old and commented out
1804 capping_global and capping_static. Fix comments regarding
1805 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
1807 * parser-defs.h: Add "extern" to start of variable declarations so
1808 we don't end up with commons.
1809 * parse.c: Define these variables.
1811 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it
1814 Mon Mar 7 13:00:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1816 * alpha-tdep.c: Change value to value_ptr.
1818 Sun Mar 6 17:36:53 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1820 * solib.c (elf_locate_base): New function to locate the address
1821 of the dynamic linker's runtime structure in the dynamic info section.
1822 * solib.c (locate_base): Use it instead of iterating over the list
1823 of mapped address segments.
1824 * solib.c (look_for_base, bfd_lookup_symbol): Removed, no longer
1827 Fri Mar 4 09:50:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1993 When looking for '\0', don't increment bufptr and addr if bufptr
1994 started out already at limit. If an error happens on fetching the
1995 first character, don't print the string.

2038 which performs one (the check_sigtramp2 one) of the functions
2039 which had been handled by the step_resume_breakpoint. For each
2040 use of the step_resume_breakpoint, make it still use the
2041 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
2043 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
2044 When setting the frame address of the step resume breakpoint, set
2045 it to the address for frame *before* the call instruction is
2046 executed, not after.

2052 read_register and then putting it back in target format with

2056 #if 0 unused include of opcode/mips.h.
2058 * symfile.h: Don't declare arguments for coff_getfilename.

2121 access & cache stuff) to use new ASI access macros in sparclite.h.
2122 Also make it easy to access second serial port.

2252 (it was inconsistent and namespace-wrong) to NM_M3_H.
2253 * m3-nat.c (mach_really_wait): Change parameter name to ourstatus.
2254 (m3_open): New function.
2256 * TODO: Update Mach section.
2258 * Makefile.in: Remove "rapp" stuff; it is superseded by gdbserver.
2260 Sun Feb 6 13:26:21 1994 Per Bothner (bothner@kalessin.cygnus.com)
2262 * printcmd.c (printf_command): Add missing single-letter
2263 backslash-escape sequences, and improve error message.
2265 Sun Feb 6 06:55:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2267 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
2268 rather than trying to shove an int into a pointer and back out
2269 again. This avoids compiler warnings.
2271 * defs.h (alloca): Declare as void *, not char *, on hpux.
2272 Don't prototype it, just declare the return type.
2274 Sun Feb 6 03:25:41 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2276 * config/i386/tm-sun386.h, config/i386/tm-symmetry.h
2277 (REGISTER_CONVERT_TO_RAW): Add missing backslash.
2279 Sat Feb 5 08:03:41 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2281 * remote-mips.c (mips_fetch_registers): If regno is FP_REGNUM or
2282 ZERO_REGNUM, just read it as zero without talking to the board.
2284 * config/i386/tm-i386aix.h (REGISTER_CONVERT_TO_RAW): Add missing
2286 * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
2287 to store_floating, not nonexistent variable len.
2289 * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):
2291 (mips_store_word): Change calling convention to return errors, and
2292 to provide old contents if the caller wants it.
2293 (mips_xfer_memory): Deal with errors from mips_store_word.
2294 * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT
2295 define now that remote-mips.c doesn't use BREAKPOINT.
2297 * remote-mips.c (mips_create_inferior): Call warning if arguments
2298 specified, and then execute "set args" command. Call error, not
2299 mips_error, if executable file not specified.
2301 * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
2304 * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast
2307 Sat Feb 5 05:27:05 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2309 * value.h (print_longest): Rename "value" to "val" in prototype
2310 declaration because some compilers don't like arguments whose
2311 names are the same as types.
2312 * remote.c (remote_xfer_memory): Cast "myaddr" to unsigned char *
2313 before passing it to remote_*_bytes.
2315 Fri Feb 4 15:53:18 1994 Steve Chamberlain (sac@cygnus.com)
2317 * h8500-tdep.c (saved_pc_after_call): The size of the
2318 pc is memory model dependent. (segmented_command,
2319 unsegmented_command, _initialize_h8500_tdep): New commands to
2320 change memory model.
2321 * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
2323 * remote-hms.c (hms_load): Remove breakpoints when loaded.
2324 (hms_wait): Use new status structure
2325 (hms_open): Push the target here. (hms_before_main_loop): Not
2326 here. (supply_val, hms_fetch_register, hms_store_register): Cope
2327 with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
2328 * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
2329 all registers in a compact way.
2331 Fri Feb 4 07:41:13 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2333 * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
2334 as CORE_ADDR to match definition in rs6000-tdep.c.
2336 Fri Feb 4 01:14:20 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2338 * dwarfread.c (process_dies): Skip nested TAG_compile_unit DIEs.
2339 * dwarfread.c (add_partial_symbol): Do not enter opaque aggregate
2340 definitions into the psymtab.
2342 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2344 * m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
2345 a special exceptionSize for the 68332.
2347 * remote-udi.c (udi_attach): If no arguments, print error.
2349 Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
2351 * Makefile.in (VERSION): Bump to 4.12.1
2352 * NEWS, README: Update to match 4.12 release.
2354 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2356 * command.c (empty_sfunc): New function.
2357 (add_set_cmd): Use it instead of not_just_help_class_command.
2358 (not_just_help_class_command): Change calling convention back to
2359 what it was before yesterday's change.
2361 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
2362 of the type if present.
2364 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2366 * printcmd.c (decode_format): Don't blithely set the size for
2367 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
2369 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
2370 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
2371 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
2372 always just check against INT_MIN and INT_MAX (this also fixes things
2373 if sizeof (long) > sizeof (int), e.g. Alpha).
2374 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
2375 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
2376 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
2377 BUILTIN_TYPE_UNSIGNED_LONGEST.
2378 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
2379 longest_int and longest_unsigned_int.
2380 * value.h (struct value): Just align to LONGEST, rather than worrying
2381 about CC_HAS_LONG_LONG.
2382 * valarith.c (value_binop): Figure out type ourself based on
2383 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
2384 point is that we don't depend on CC_HAS_LONG_LONG anymore.
2385 * valprint.c (val_print_type_code_int): Just call
2386 extract_unsigned_integer directly, rather than going through
2388 * printcmd.c (decode_format): Remove code which would sometimes
2389 change 'g' size to 'w' for integers. print_scalar_formatted handles
2390 printing huge integers well enough, thank you.
2392 * command.c (add_set_cmd, not_just_help_class_command): Change
2393 to make this the sfunc, not cfunc, since that is how we call it.
2394 * command.h: Comment difference between sfunc and cfunc.
2395 * demangle.c (set_demangling_command): Add third arg since that
2396 is how it is called.
2397 (_initialize_demangler): Use sfunc, not cfunc, for
2398 set_demangling_command, since that is how it is called.
2399 Remove show_demangling_command; it has no effect.
2401 * command.c (shell_escape): Report errors correctly (with error
2402 message from strerror).
2404 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2406 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
2407 x_scnlen.l rather than x_scnlen to match corresponding change in
2410 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2412 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
2413 Change comments regarding TYPE_CODE_BOOL.
2414 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
2415 regardless of the language.
2416 (value_true): Just call value_logical_not regardless of language.
2417 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
2418 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
2419 * language.h: Improve comment for la_builtin_type_vector.
2420 * m2-lang.c (_initialize_m2_language): Don't add any fields to
2421 builtin_type_m2_bool.
2423 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
2425 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
2426 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
2428 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2430 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
2431 by restarting the ioctl.
2433 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2435 * target.h (target_wait): Add comment about calling
2436 return_to_top_level.
2438 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2440 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
2441 additional arguments.
2442 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
2444 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
2446 * sparc-stub.c: Remove unnecessary #include of memory.h.
2448 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2450 * mips-tdep.c: Remove code which sets saved_regs from
2451 init_extra_frame_info and put it in new function mips_find_saved_regs.
2452 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
2453 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
2454 check if it is NULL and call mips_find_saved_regs if so.
2456 * remote-mips.c: Use unfiltered, not filtered, output most places.
2458 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
2459 backtrace. Revise comments.
2461 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2463 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
2464 alpha and irix. The _sigtramp case has to be handled properly
2465 in the tdep files if we have no ecoff debugging info.
2466 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
2467 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
2468 without PC_REGNUM kludge.
2469 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
2470 Clean up handling of mips sigtramp frames, improve comments.
2472 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2474 * paread.c (read_unwind_info): Fix typo.
2476 * paread.c (pa_symtab_read): Update the "check_strange_names"
2477 filter to match GCC's current output. Filter out section symbols
2478 (which the HP linker sometimes puts in the wrong place).
2480 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2482 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
2484 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
2486 * Makefile.in: Remove all references to sparcly-nat.c.
2488 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
2489 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
2490 duplicating serial.h and target.h.
2492 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
2493 are not used anywhere (a 5 Oct 1993 change removed the uses).
2495 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
2496 * config/m68k/es1800.mt: Add comment.
2497 * remote-es.c: Extensive changes to update to current conventions.
2499 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
2500 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
2501 to achieve the desired timeout.
2502 * serial.h (serial_t): Add field timeout_remaining.
2504 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2506 * c-exp.y (yylex): Reenable nested type code.
2508 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2510 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
2512 * remote-mips.c (mips_ops): Fix docstring.
2514 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
2516 * config/m68k/tm-monitor.h: Changes to bring this into accordance
2517 with the old tm-m68k-em.h:
2518 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
2519 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
2520 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
2521 Add FIXME regarding GET_LONGJMP_TARGET.
2523 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
2524 * infptrace.c (kill_inferior): Add comments.
2525 * main.c (quit_command): Call target_close after we kill or
2527 * remote-udi.c (udi_close): Don't error() if QUITTING.
2529 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
2531 * configure.in: Make m68k-coff and aout add monitor support in
2532 addition to the standard serial support.
2534 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2536 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
2539 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2541 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
2542 * elfread.c (record_minimal_symbol_and_info),
2543 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
2545 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2547 * i386-stub.c: Add ".text" right before "mem_fault:".
2549 * main.c (baud_rate): Add FIXME comment about printing -1 value.
2551 * remote-utils.c (usage): Fix message to be accurate and conform
2552 more closely to normal conventions.
2554 * remote-utils.c (gr_files_info): Have the exec_bfd test control
2555 whether to show information about exec_bfd, and not control whether
2556 to show information about device and speed.
2558 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
2559 usage message, don't dump core.
2561 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
2562 for variable size array.
2563 (bug_fetch_register, bug_store_register): Rename "value" to
2564 "fpreg_buf" because some compilers don't like variables whose
2565 names are the same as types.
2566 (bug_store_register): Use a cast when converting char * to
2569 * symmisc.c (maintenance_print_symbols): Don't refer to the name
2570 of the command in error message (the text was referring to the old
2571 name of the command).
2573 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
2575 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
2576 full details on structure elements without names. This partially
2577 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
2578 of those changes was accidental.
2580 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
2581 defined, make it an error to specify a single argument which is not
2584 * Makefile.in (version.c), main.c (print_gdb_version): Use
2585 host_alias and target_alias, not host_canonical and
2586 target_canonical, to print configuration.
2588 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2590 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
2591 of builtin_type_long. It is necessary to get a type which is
2592 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
2594 Fix many sins which will come up in 32 bit x 64 bit GDB, and
2595 various miscellaneous things discovered in the process:
2596 * printcmd.c, defs.h (print_address_numeric): New function.
2597 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
2598 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
2599 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
2600 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
2602 * utils.c, defs.h (gdb_print_address): New function.
2603 * expprint (dump_expression), gdbtypes.h: Use it.
2604 * breakpoint.c (describe_other_breakpoints),
2605 symmisc.c (dump_symtab, print_symbol):
2606 Use filtered not unfiltered I/O.
2607 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
2608 just run gdb under a debugger for this (and it had problems with
2609 printing addresses, how to print b->shadow, etc.).
2610 * buildsym.c (make_blockvector), core.c (memory_error),
2611 exec.c (print_section_info), maint.c (print_section_table),
2612 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
2613 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
2614 Add comments saying code is broken. Marked with "FIXME-32x64".
2615 * dbxread.c (process_one_symbol), partial-stab.h (default),
2616 remote-vx.c (vx_run_files_info):
2617 Don't cast int being passed to local_hex_string.
2618 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
2619 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
2621 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
2623 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
2624 * source.c: Include <sys/types.h> regardless of USG.
2626 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2628 * valops.c (value_assign): Set `type' after coercing toval.
2629 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
2630 Use extract_unsigned_integer to get the address of a reference.
2632 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2634 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
2635 AIX can use ? instead of \ for continuation. Deal with it.
2637 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
2638 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
2639 the HP compiler in ANSI mode doesn't like.
2641 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
2642 based on USG, rather than defining HAVE_SIGSETMASK to an
2643 expression containing defined. Having a macro used in #if expand
2644 to an expression containing "defined" is undefined according to
2645 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
2648 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
2650 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2651 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
2653 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
2655 * ch-exp.y (match_string_literal): Allow a zero-length string.
2656 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
2658 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2660 * i386aix-nat.c (i386_float_info): Reverse order of registers before
2661 passing them to print_387_status.
2662 (print_387_status): Don't subtract top from 7 before using it.
2663 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
2664 from 7; the above explains it.
2666 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2668 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
2669 pointer value when fixing up the frame at the start of a function.
2671 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
2673 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
2674 Sparc from the stack.
2676 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2678 * remote-mips.c (mips_initialize): Clear mips_initializing via
2679 cleanup chain, not directly.
2681 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
2682 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
2683 munging the timeout due to the limited range of c_cc[VTIME].
2685 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
2686 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
2687 m3-nat.c (m3_create_inferior): Pass it.
2688 * procfs.c: Remove ptrace function. It was declared in a way which
2689 conflicted with the prototype in unistd.h on Solaris.
2691 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2693 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
2694 in the sigcontext if it is a signal trampoline frame.

2696 Define for Solaris2.
2698 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
2700 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
2701 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
2702 tm-sparc.h so they can be overridden if necessary.
2704 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
2706 * lynx-nat.c: Add Sparc support.
2707 * sparcly-nat.c: Remove. It's useless.
2708 * config/sparc/nm-sparclynx.h: Rewrite.
2709 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
2711 * config/sparc/tm-sparclynx.h: Rewrite.

2715 * rs6000-pinsn.c: Use the new disassembler in the opcodes
2716 directory. Old code was discarded, since the new opcode table has

2721 * Makefile.in (realclean): Remove info files per make-stds.texi.
2723 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2725 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
2726 if N_SO_ADDRESS_MAYBE_MISSING is defined.
2727 * config/sparc/tm-sun4sol2.h: Define it.
2729 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2731 * printcmd.c (print_address_symbolic): Unconditionally use msymbol

2739 * hppab-nat.c (call_ptrace): Delete redundant function.
2740 (kill_inferior, attach, detach, child_resume): Likewise.
2741 (child_xfer_memory): Likewise.
2743 * hppah-nat.c (call_ptrace): Delete redundant function.
2744 (kill_inferior, attach, detach, child_resume): Likewise.
2746 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
2748 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
2750 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
2752 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
2753 (CHILD_XFER_MEMORY): Define.
2754 (PT_*): Define so that generic infptrace.c code can be used.
2756 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2758 * xcoffread.c (xcoff_symfile_read): Make second parameter a
2759 struct section_offsets *, not a (nonexistent) struct section_offset *.
2761 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
2762 internal_xcoff_symtab, not an array of one of them. Change lots of
2763 "main_aux" to "&main_aux" and so on.
2765 * coffread.c, xcoffread.c: Include <coff/internal.h>
2768 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2770 * coffread.c (coff_getfilename): Make it not static.
2772 * xcoffread.c (read_xcoff_symtab): complain() not abort().
2774 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
2775 a completely gratuitous difference between xcoffread.c and coffread.c).
2777 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2779 * infrun.c (wait_for_inferior): Don't set frame for
2780 step_resume_breakpoint for IN_SIGTRAMP cases.
2782 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
2783 breakpoint.c (bpstat_what): Move step_resume from its own field of
2784 the struct bpstat_what into the main_action. Make it override
2785 other breakpoints. This is a conservative change in the sense
2786 that before the step resume breakpoint was a breakpoint.c
2787 breakpoint, hitting the step resume breakpoint overrode even
2788 calling bpstat_stop_status.
2790 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2792 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
2793 in case execution was stopped in the called function.
2794 * stack.c (print_frame_info, frame_info): If backtracing through
2795 a call dummy, handle the starting source line number on a line
2796 boundary like backtracing through sigtramp.
2797 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
2798 for call dummy frame right. Remove old test for dummy frame,
2799 it has been unused at least since gdb-3.5.
2800 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
2803 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

2807 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2809 * infrun.c (signals_info), target.c (target_signal_from_name):
2810 Use ugly casts to avoid enumvar < enumvar or enumvar++.
2812 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2814 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
2815 * inflow.c (terminal_ours_1): When discussing how to deal with the
2816 tty state, make note of query() as well as readline.

2819 signals for which stop and print are cleared by default.
2821 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2823 * config/pa/tm-hppa.h (unwind_table_entry): Use one of the
2824 reserved fields to hold a stub unwind entry type. Fix typo.

2829 by linker stub unwind descriptors.
2830 (frameless_function_invocation): Likewise.
2831 (frame_chain_valid): Likewise.
2832 * paread.c (compare_unwind_entries): New function for sorting
2833 unwind table entries.
2834 (read_unwind_info): Rewrite to remove dependency on host endianness.
2835 Read in data from the $UNWIND_END$ subspace which contains linker
2836 stub unwind descriptors. Merge that data into the basic unwind
2839 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
2841 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2843 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
2844 from either the symbol name or the auxent.
2845 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
2848 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
2850 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
2852 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2854 * README: Update notes for alpha port.
2856 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2858 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
2859 for operation fault, constraint fault, and type fault.
2861 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2863 * Makefile.in (init.c): Add comment explaining formatting conventions.
2865 * c-exp.y (parse_number): Assign to temporary between the right
2866 shifts, to work around a bug in the SCO compiler.
2868 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
2869 Add various files which were added to GDB recently.
2871 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
2874 * Makefile.in: Add mostlyclean target.
2876 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2880 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
2882 * main.c (show_commands): Make return type of extern
2883 history_get be HIST_ENTRY, rather than struct _hist_entry.
2884 (The latter loses with the upcoming merged readline.)
2886 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2888 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
2889 const char *, not char *.
2891 * symtab.h (struct symbol): Make section short, not unsigned short.
2893 * symtab.c (lookup_symbol): Add comment about QUIT here.
2895 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
2897 * c-exp.y (parse_number): Check for overflow regardless of range
2898 checking. Fix overflow check to use unsigned LONGEST, not
2901 * c-exp.y (parse_number): Make it so that integer constants are
2902 builtin_type_long_long if builtin_type_long isn't big enough or if
2903 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
2905 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
2906 Print our "()" first, then recurse for the target type.
2908 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2910 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
2912 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
2914 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2916 * utils.c (request_quit): Re-establish signal handler regardless
2919 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
2921 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2923 * i960-tdep.c: Include target.h.
2925 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
2927 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
2929 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2931 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
2932 changes (status -> ourstatus; declare status, etc.).
2933 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
2935 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2937 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
2939 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2941 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
2943 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2945 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
2947 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2949 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
2951 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2953 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
2954 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
2956 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
2959 Add search to target vector (#if 0'd until after 4.12):
2960 * target.h (to_search, target_search): Add.
2961 * gdbcore.h, core.c (generic_search): Add.
2962 * remote.c (remote_search): Add.
2963 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
2966 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
2967 is on, call find_pc_function rather than relying just on the minimal
2968 symbols (probably only matters for symbol readers which don't put
2969 statics in the minimal symbols, but changing this strikes me as
2970 not conservative enough).
2971 Initialize name_location in all cases.
2972 If no symbol and no msymbol, don't print anything symbolic.
2974 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2976 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2978 * printcmd.c (print_address_symbolic): Make it search the
2979 symtabs for variables as well as functions. Add `set print
2980 fast-symbolic-addr' and default it to fast (the old way).
2981 Print line numbers for data items as well as functions.
2983 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2984 address, if a symbol is found (take two more args pointing to
2985 where to store these results).
2987 * symtab.h (find_addr_symbol): Add prototype.
2989 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2991 * objfiles.h: Fix comments to reflect the fact that the phrase
2992 "top of stack" always refers to where the pushing and popping takes
2993 place, regardless of whether it is at the highest or lowest address.
2995 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2997 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2998 compiler generated tag names.
2999 * mdebugread.c (parse_type): Handle cross references to qualified
3001 * valops.c (value_struct_elt): Improve error message if the
3002 address of a method is requested from an object instance.
3003 * valops.c (search_struct_method): Make name_matched non-static
3004 to get it initialized correctly.
3005 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
3006 exclude segment register which are not writable on newer SCO versions.
3008 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3010 * go32-xdep.c: Remove unused function uerror.
3011 (sigsetmask): Declare return type. Declare argument (to match the
3012 way it is called). Explicitly return 0.
3014 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
3016 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
3017 partial_symbol): Shrink the storage sizes of symbols, by making
3018 enums into 1-byte bitfields when compiled __GNUC__, moving all the
3019 enums and small ints to the end of each struct to improve
3020 alignment, and switching the section number from int to unsigned
3023 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
3025 * symtab.c (find_addr_symbol): New routine that will find the nearest
3026 symbol associated with an address. It does so by exhaustive
3027 search of the symtabs, so it's slow but complete.
3029 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
3031 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
3032 to [0,0] rather than [0, end of first source file]. This avoids
3033 problems with other parts of GDB looking for linetables in the
3034 _globals_ symtab. Eliminate variables num_object_files and
3035 first_object_file_end.
3037 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3039 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
3040 (pop_frame): Restore PC2 and LR0 from dummy frames.
3041 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
3042 (setup_arbitrary_frame): Handle 3 args and set up real frames.
3043 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
3044 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
3045 (SETUP_ARBITRARY_FRAME): Define.
3047 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3049 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
3051 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3053 * remote-udi.c (udi_resume): Correct prototype.
3055 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3057 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
3058 hppa_frame_find_saved_regs.
3059 * hppa-tdep.c (dig_fp_from_stack): Delete function.
3060 (prologue_inst_adjust_sp): New function.
3061 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
3062 (skip_prologue): Completely rewrite to use unwind information.
3063 (hppa_frame_find_saved_regs): Likewise.
3065 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3067 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
3068 to convert a signal number with appropriate bounds checking.
3070 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
3072 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3074 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
3075 print a newline to end the display anyway.
3077 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
3078 coprocessor status regs) when popping a frame. This fixes
3079 float exceptions that occur after calling inferior functions.
3081 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
3082 Read and write the fsr (float status register) to/from the child
3083 process along with the float regs. Remove Peter Schauer's change
3084 of May 24 '93, which has higher overhead and doesn't solve the
3085 real problem (which was that FSR wasn't being set).
3087 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
3089 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
3090 stack overflow check isn't right after the register stack
3091 adjustment instruction. Metaware R2.3u compiler moves other
3092 things in front of it. This fix isn't perfect but is what's
3095 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3097 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
3099 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
3100 character filenames.
3101 * configure.in: Change accordingly.
3103 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
3105 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
3106 _filtered io routines from these two files.
3108 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3110 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
3111 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
3112 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
3114 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
3116 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3118 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
3119 printing to gdb_stderr.
3121 * remote-udi.c (udi_kill): Don't close the connection, just set
3122 inferior_pid to zero.
3123 (udi_mourn): Call remove_breakpoints.
3125 * remote-udi.c: Remove obsolete need_artificial_traps comment.
3127 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
3129 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3131 * symtab.c (lookup_symbol): Don't try adding .c to the name.
3133 * remote-bug.c: At the start of each section, reset srec_frame
3136 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
3137 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
3138 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
3139 code which looks for those two waitkinds. Use switch statement.
3140 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
3141 CHILD_SPECIAL_WAITSTATUS.
3143 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
3144 * Move target_signal_from_host, target_signal_to_host, and
3145 store_waitstatus from inftarg.c to target.c. procfs needs them.
3146 * target.c: Include "wait.h" and <signal.h>.
3147 * target.h, infrun.c (proceed), proceed callers: Pass new code
3148 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
3149 enums being treated as unsigned and is cleaner.
3150 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
3152 * infcmd.c (signal_command), infrun.c (signals_info):
3153 Don't allow user to specify numeric equivalent of
3154 TARGET_SIGNAL_DEFAULT.
3156 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
3158 * config/alpha/alpha-netware.mt: New target support for Alpha
3160 * configure.in: Add alpha-*-netware* target.
3162 Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
3164 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
3166 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3168 * target.h: Add enum target_waitkind, enum target_signal, and
3169 struct target_waitstatus. Change status argument to target_wait to
3170 be struct target_waitstatus * instead of int *.
3171 * target.h, infrun.c, all targets: Change type of signal arguments
3172 to resume(), proceed(), and target_resume() from int to enum
3174 * All targets (*_wait, *_resume): Change accordingly.
3175 * infcmd.c (program_info, signal_command), throughout infrun.c,
3176 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
3177 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
3178 signal code stuff right with the new signals would be non-trivial).
3179 * inferior.h (stop_signal): Make it enum target_signal not int.
3180 * target.c, target.h (target_signal_to_string, target_signal_to_name,
3181 target_signal_from_name): New functions.
3182 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
3183 store_waitstatus): New functions.
3184 * procfs.c (procfs_notice_signals): Use them.
3185 * i960-tdep.c (i960_fault_to_signal): New function, to replace
3187 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
3189 * objfiles.c (build_objfile_section_table): Don't abort() if
3190 objfile->sections is already set.
3192 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
3193 to match recent change to exec.c.
3197 * main.c (print_gdb_version): Change year to 1994.
3199 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
3200 * Makefile.in (NONSRC): Add ChangeLog-93.
3202 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3204 * stabsread.c (read_type): Allow defining several type numbers
3205 at once (e.g. "(1,2)=(3,4)="...).
3207 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
3209 * breakpoint.c (frame_in_dummy): Check PC as well as frame.
3211 Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3213 * mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
3214 to process_one_symbol.
3215 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
3216 avoid caching a bad endaddr in find_pc_partial_function.
3218 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3220 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
3222 Sat Jan 1 04:35:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3224 * infrun.c (wait_for_inferior): Do not step or step resume past
3225 the end of a one-line function we just stepped into.
