1383 if no unwind descriptor is found.
1385 * tm-hppa.h (NUM_REGS): Bump to 128 registers.
1386 (REGISTER_NAMES): Add entries for "right-half" of FP registers.
1387 (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs
1388 differently. All registers are four bytes.
1389 (REGISTER_BYTES, REGISTER_BYTE): Simplify now that all registers are
1391 (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.
1393 * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
1394 registers as both single and double values (fetching 2nd 32bit half
1395 as necessary). Annotate each register printed with its precision.
1397 * paread.c (read_unwind_info): Fix off-by-one error.

1405 * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
1406 regarding using the PC--using the PC is necessary and all the
1407 FIXME comments in the world won't make it go away.
1409 * valops.c (value_at, value_at_lazy): Give error if we dereference
1411 * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
1412 * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.
1414 * stabsread.c (patch_block_stabs): Add comment about what happens
1415 if the definition is in another compilation unit from the stab.

1421 * main.c (complete_command): New command, from Rick Sladkey
1422 <jrs@world.std.com>.
1423 (symbol_completion_function): Don't declare rl_point and
1424 rl_line_buffer; they are now declared in readline.h.
1425 (show_commands): Don't declare history_base; it is declared in
1427 * command.c (lookup_cmd): Don't delete trailing whitespace.
1428 Reverts change of 14 May 1989.
1430 Wed Mar 23 16:14:52 1994 Stu Grossman (grossman at cygnus.com)
1432 * minsyms.c (prim_record_minimal_symbol): Move section deduction
1433 code from prim_record_minimal_symbol_and_info() to here. Callers
1434 of the latter can legitimately supply a section number of -1.
1436 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1438 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
1439 member functions have an element in args for a (nonexistent) this
1442 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1444 * config/pa/tm-hppao.h (NO_PC_SPACE_QUEUE_RESTORE): Define.
1446 * hppa-tdep.c (hppa_pop_frame): Do not restore the PC space
1447 queue if NO_PC_SPACE_QUEUE_RESTORE is defined.
1449 * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
1450 for the structure's type. All callers changed.
1452 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
1453 for each structure argument rather than assuming it's either
1454 true or false for all structure arguments.
1456 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
1457 on the length structure passed, not the compiler used.
1459 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
1460 argument for the structure's type.
1462 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1464 * values.c (set_internalvar): Don't set var->value until we are

1472 * symmisc.c (maintenance_check_symtabs): New function to check
1473 consistency of psymtabs and symtabs.
1474 * symtab.h (maintenance_check_symtabs): Add prototype.
1475 * maint.c: Add new `maint check-symtabs' command.
1476 * config/i386/tm-i386aix.h, config/i386/tm-sun386.h,
1477 config/i386/tm-symmetry.h (REGISTER_CONVERT_TO_RAW): Fix typo.

1482 * config/i386/xm-symmetry.h: Add missing #endif.
1483 * config/i386/nm-symmetry.h (NO_PTRACE_H): Add for Dynix.
1484 * config/i386/symmetry.mt (TDEPFILES): Add i386-tdep.o.
1485 * config/i386/symmetry.mh (NAT_FILE, NATDEPFILES): Add.

1489 * hppa-tdep.c (hppa_fix_call_dummy): Use value_ptr.
1490 (hppa_push_arguments): Likewise.
1492 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
1494 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
1495 improve remote debugging efficiency. Also fixed problems with
1496 doing function calls for programs with no entry points.
1497 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
1498 entry_point_address.
1499 * inferior.h (PC_IN_CALL_DUMMY): ditto.
1500 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
1501 parse_lines): Pass section_offsets info to these routines so that
1502 we can relocate symbol table entries upon readin.
1503 * (psymtab_to_symtab_1): Set symtab->primary to tell
1504 objfile_relocate to do relocations for our symbols.
1505 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
1506 (which hang off of the symbol table).
1507 * Use prim_record_minimal_symbols_and_info instead of
1508 prim_record_minimal_symbols to supply section info to make minimal
1509 symbol relocations work.
1510 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
1511 -1, try to deduce it from ms_type.
1512 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
1513 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
1514 add code to relocate objfile->sections data structure.
1515 * remote.c (get_offsets): Use new protocol message to acquire
1516 section offsets from the target.
1517 * (remote_wait): Get rid of relocation stuff. That's all handled
1518 by objfile_relocate now.
1519 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
1520 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
1522 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
1524 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
1526 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
1528 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
1529 can no longer set this at run time.
1530 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
1531 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
1532 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
1533 sparc-tdep.c compiles).
1534 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
1536 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1538 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
1539 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
1540 * configure.in: Recognize m68*-cisco*-*.
1542 * Makefile.in (TAGS): Use variables directly, rather than using
1543 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
1544 and means that these filenames no longer need be unique across all
1545 the config/* directories.
1546 * configure.in: Put the config/*/ into TM_FILE, etc.
1548 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
1549 and trapv exceptions.
1551 * target.h (struct section_table), objfiles.h (struct obj_section):
1552 Change name of field sec_ptr to the_bfd_section. More mnemonic
1553 and avoids the (sort of, for the ptx compiler) name clash with
1554 the name of the typedef.
1555 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
1556 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
1558 * utils.c: Include readline.h.
1559 * Makefile.in (utils.o): Add dependency.
1561 * remote.c (getpkt): Add support for run-length encoding.
1563 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1565 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
1567 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1569 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
1570 prim_record_minimal_symbol.
1573 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
1574 computing their offset from the start of the old buffer and adding
1575 to the new buffer, rather than by assuming we can add the
1576 difference between the old buffer and the new buffer (it might not
1577 fit in an int). Merge in cosmetic differences from emacs regex.c
1578 version of this macro.
1580 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1582 * Makefile.in (install-only): Fix use of program_transform_name.
1584 Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1586 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
1587 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
1588 so I'm nuking the command.
1589 * symtab.c (find_addr_symbol): Comment out, no longer used.
1591 * main.c (main): Don't init_source_path for the -cd argument. Now
1592 that source_path doesn't contain the current_directory from when
1593 GDB started up, init_source_path is no longer useful (and is
1594 harmful because it clobbers a source_path set in $HOME/.gdbinit).
1596 * TODO: Remove item about line numbers being off. It is useless
1597 and confusing without a reproducible test case (it mentions
1598 proceed(), but I was able to step through proceed without trouble).
1600 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1602 For Sunos 4.x targets, enable gdb to set breakpoints in shared
1603 library functions before the executable is run. Retrieve dynamic
1604 symbols from stripped executables.
1605 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
1606 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
1607 symtab.c (list_symbols): Handle mst_solib_trampoline.
1608 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
1609 for all targets, remove IBM6000_TARGET dependencies.
1610 * dbxread.c (read_dbx_dynamic_symtab): New function.
1611 * dbxread.c (dbx_symfile_read): Use it.
1612 * dbxread.c (SET_NAMESTRING): Set namestring to
1613 "<bad string table index>" instead of "foo" if the string index is
1615 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
1617 * symtab.c (list_symbols): Take from_tty as parameter and pass it
1618 to break_command. Handle mst_file_* minimal symbol types.
1619 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
1621 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)
1623 * c-exp.y(yylex): fix potential memory overflow.
1625 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1627 * environ.c (set_in_environ): Eliminate special handling of PATH and
1629 * putenv.c: Removed, conflicts with system declaration of
1630 putenv on RS/6000 running AIX 3.2.5, and above change makes it
1632 * Makefile.in: Change accordingly.
1633 * procfs.c (procfs_create_inferior): Change comment accordingly.
1635 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)
1637 * rs6000-tdep.c: Change value to value_ptr.
1639 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1641 * i386m3-nat.c: Include floatformat.h.
1642 (get_i387_state): Use memset not bzero.
1646 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
1647 ieee-float.h to floatformat.h.
1649 * valprint.c (val_print_string): Ignore error if the error
1650 happened after a terminating '\0'.
1652 * c-valprint.c (c_val_print): Never add 1 to return value from
1653 val_print_string; just return what it returns.
1655 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
1656 looping through all of the enums.
1657 * infrun.c (signals_info): Use it.
1659 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1661 * main.c (main): When printing warning about bad baud rate, don't
1662 use warning(); it relies on current_target which isn't set up yet.
1664 * breakpoint.c (_initialize_breakpoint): Update docstring for
1665 tbreak to match what the code actually does. Don't mention tbreak
1666 in docstrings for "enable once" or "enable breakpoints once".
1668 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1670 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
1671 while (0). That defeats the whole purpose of using do . . . while (0).
1672 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
1673 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
1674 using a ?: expression as an lvalue is not portable.
1676 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
1677 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
1678 'p' and 'r' symbol descriptors into a single symbol to look for a
1680 * README, config/sparc/tm-sparc.h: Update comments.
1682 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1684 * mdebugread.c (parse_type): Do not complain for types with
1685 an `indexNil' aux index, these are simply undefined types.
1686 Remove indexNil check from caller of parse_type.
1687 * mdebugread.c (parse_partial_symbols): Do not enter
1688 stGlobal, scCommon symbols into the minimal symbol table, their
1689 value is the size of the common, not its address.
1690 Handle scInit, scFini, scPData and scXData sections.
1691 Use minimal symbol type mst_file_* for stLabel symbols, instead of
1693 Enter stProc symbols into the global_psymbols list once, not into
1694 the static_psymbols_list.
1695 Get rid of dummy psymtab if it is empty, to allow proper detection
1696 of stripped executables.
1697 * mdebugread.c (cross_ref): Allow cross references to Fortran
1700 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1702 * stabsread.c (common_block_end, fix_common_block): Stash the
1703 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
1704 as to not assume that a pointer fits in an enum.
1706 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
1708 * os9kread.c (fill_sym): check compiler verion number for pre-
1710 * os9kread.c (os9k_process_one_symbol): address of symbol is
1711 relative to section not module.
1712 * stabsread.c (define_symbol): add symbol type 's' as local
1714 * remote-os9k.c: add command 'set monitor_log' to turn on or off
1716 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
1717 * remote-os9k.c: fix bug in 'set remotebaud' function.
1718 * remote-os9k.c (rombug_link): minimize checking so to improve
1720 * symfile.c (symbol_file_command): check if failed to link, also make
1721 the command be able to accept more than one filenames.
1722 * target.c (target_link): check if failed to link with rombug.
1723 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
1725 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1727 * remote-es.c (es1800_child_ops): Don't declare it static.

1735 * dbxread.c: New variable lowest_text_address.
1736 (record_minimal_symbol, read_dbx_symtab): Set it.
1737 (read_dbx_symtab): Use lowest_text_address + text_size instead of
1738 end_of_text_address.
1739 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
1741 * dbxread.c (end_psymtab): Remove old and commented out
1742 capping_global and capping_static. Fix comments regarding
1743 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
1745 * parser-defs.h: Add "extern" to start of variable declarations so
1746 we don't end up with commons.
1747 * parse.c: Define these variables.
1749 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it
1752 Mon Mar 7 13:00:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

1756 Sun Mar 6 17:36:53 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1758 * solib.c (elf_locate_base): New function to locate the address
1759 of the dynamic linker's runtime structure in the dynamic info section.
1760 * solib.c (locate_base): Use it instead of iterating over the list
1761 of mapped address segments.
1762 * solib.c (look_for_base, bfd_lookup_symbol): Removed, no longer
1765 Fri Mar 4 09:50:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1784 * ch-exp.y (match_simple_name_string): Accept '_' as well as an
1785 alphabetic character as the start of a name.
1787 * sparclite/Makefile.in (all install): Build and install aload.
1789 * configure.in: Accept i[34]86-*-*sysv32 because that is what
1790 config.guess and config.sub produce.
1792 * mips-tdep.c: Change value to value_ptr.
1794 Wed Mar 2 09:17:55 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1796 * breakpoint.c, breakpoint.h, c-valprint.c, ch-valprint.c,
1797 cp-valprint.c, eval.c, expprint.c, findvar.c, language.c,

1809 I386_REGNO_TO_SYMMETRY check in case it is needed for Dynix
1811 * config/i386/nm-symmetry.h: Change KERNEL_U_ADDR. Move
1812 stuff from PTRACE_READ_REGS, PTRACE_WRITE_REGS macros to
1813 symm-nat.c. Define CHILD_WAIT and declare child_wait().
1814 * config/i386/tm-symmetry.h: Remove call function stuff; stuff in
1815 tm-i386v.h is apparently OK.
1816 * config/i386/xm-symmetry.h [_SEQUENT_]: Define HAVE_TERMIOS not
1817 HAVE_TERMIO. Define MEM_FNS_DECLARED, NEED_POSIX_SETPGID, and
1820 Wed Mar 2 11:31:08 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)

1929 just print the error message rather than calling error(). Don't
1930 access *(bufptr-1) if bufptr points to the start of the buffer.
1931 When looking for '\0', don't increment bufptr and addr if bufptr
1932 started out already at limit. If an error happens on fetching the
1933 first character, don't print the string.

1973 if we hit a bp_through_sigtramp breakpoint. Remove kludge which
1974 ignored bs->stop for a bp_step_resume breakpoint.
1975 * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
1976 which performs one (the check_sigtramp2 one) of the functions
1977 which had been handled by the step_resume_breakpoint. For each
1978 use of the step_resume_breakpoint, make it still use the
1979 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
1981 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
1982 When setting the frame address of the step resume breakpoint, set
1983 it to the address for frame *before* the call instruction is
1984 executed, not after.
1986 * mips-tdep.c (mips_print_register): Print integers using
1987 print_scalar_formatted rather than duplicating all the

1990 read_register and then putting it back in target format with

1994 #if 0 unused include of opcode/mips.h.
1996 * symfile.h: Don't declare arguments for coff_getfilename.
1998 * defs.h: Revert Kung change regarding FORCE_LONG_LONG.

2047 set up the global offset table pointer in pic compiled code.
2048 * config/mips/tm-mips.h (FIX_CALL_DUMMY): For big endian targets,
2049 error() on TYPE_CODE_FLT arguments whose size is greater than 8,
2050 swap all other TYPE_CODE_FLT arguments as mips_push_arguments
2051 ensures that floats are promoted to doubles before they are pushed

2059 access & cache stuff) to use new ASI access macros in sparclite.h.
2060 Also make it easy to access second serial port.

2205 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
2206 rather than trying to shove an int into a pointer and back out
2207 again. This avoids compiler warnings.
2209 * defs.h (alloca): Declare as void *, not char *, on hpux.
2210 Don't prototype it, just declare the return type.

2248 declaration because some compilers don't like arguments whose
2249 names are the same as types.
2250 * remote.c (remote_xfer_memory): Cast "myaddr" to unsigned char *
2251 before passing it to remote_*_bytes.
2253 Fri Feb 4 15:53:18 1994 Steve Chamberlain (sac@cygnus.com)
2255 * h8500-tdep.c (saved_pc_after_call): The size of the
2256 pc is memory model dependent. (segmented_command,
2257 unsegmented_command, _initialize_h8500_tdep): New commands to
2258 change memory model.
2259 * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
2261 * remote-hms.c (hms_load): Remove breakpoints when loaded.
2262 (hms_wait): Use new status structure
2263 (hms_open): Push the target here. (hms_before_main_loop): Not
2264 here. (supply_val, hms_fetch_register, hms_store_register): Cope
2265 with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
2266 * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
2267 all registers in a compact way.
2269 Fri Feb 4 07:41:13 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2271 * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
2272 as CORE_ADDR to match definition in rs6000-tdep.c.
2274 Fri Feb 4 01:14:20 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2276 * dwarfread.c (process_dies): Skip nested TAG_compile_unit DIEs.
2277 * dwarfread.c (add_partial_symbol): Do not enter opaque aggregate
2278 definitions into the psymtab.
2280 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2282 * m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
2283 a special exceptionSize for the 68332.
2285 * remote-udi.c (udi_attach): If no arguments, print error.
2287 Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
2289 * Makefile.in (VERSION): Bump to 4.12.1
2290 * NEWS, README: Update to match 4.12 release.
2292 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2294 * command.c (empty_sfunc): New function.
2295 (add_set_cmd): Use it instead of not_just_help_class_command.
2296 (not_just_help_class_command): Change calling convention back to
2297 what it was before yesterday's change.
2299 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
2300 of the type if present.
2302 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2304 * printcmd.c (decode_format): Don't blithely set the size for
2305 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
2307 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
2308 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
2309 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
2310 always just check against INT_MIN and INT_MAX (this also fixes things
2311 if sizeof (long) > sizeof (int), e.g. Alpha).
2312 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
2313 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
2314 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
2315 BUILTIN_TYPE_UNSIGNED_LONGEST.
2316 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
2317 longest_int and longest_unsigned_int.
2318 * value.h (struct value): Just align to LONGEST, rather than worrying
2319 about CC_HAS_LONG_LONG.
2320 * valarith.c (value_binop): Figure out type ourself based on
2321 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
2322 point is that we don't depend on CC_HAS_LONG_LONG anymore.
2323 * valprint.c (val_print_type_code_int): Just call
2324 extract_unsigned_integer directly, rather than going through
2326 * printcmd.c (decode_format): Remove code which would sometimes
2327 change 'g' size to 'w' for integers. print_scalar_formatted handles
2328 printing huge integers well enough, thank you.
2330 * command.c (add_set_cmd, not_just_help_class_command): Change
2331 to make this the sfunc, not cfunc, since that is how we call it.
2332 * command.h: Comment difference between sfunc and cfunc.
2333 * demangle.c (set_demangling_command): Add third arg since that
2334 is how it is called.
2335 (_initialize_demangler): Use sfunc, not cfunc, for
2336 set_demangling_command, since that is how it is called.
2337 Remove show_demangling_command; it has no effect.
2339 * command.c (shell_escape): Report errors correctly (with error
2340 message from strerror).
2342 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2344 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
2345 x_scnlen.l rather than x_scnlen to match corresponding change in
2348 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2350 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
2351 Change comments regarding TYPE_CODE_BOOL.
2352 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
2353 regardless of the language.
2354 (value_true): Just call value_logical_not regardless of language.
2355 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
2356 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
2357 * language.h: Improve comment for la_builtin_type_vector.
2358 * m2-lang.c (_initialize_m2_language): Don't add any fields to
2359 builtin_type_m2_bool.
2361 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
2363 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
2364 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
2366 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2368 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
2369 by restarting the ioctl.
2371 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2373 * target.h (target_wait): Add comment about calling
2374 return_to_top_level.
2376 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2378 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
2379 additional arguments.
2380 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
2382 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
2384 * sparc-stub.c: Remove unnecessary #include of memory.h.
2386 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2388 * mips-tdep.c: Remove code which sets saved_regs from
2389 init_extra_frame_info and put it in new function mips_find_saved_regs.
2390 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
2391 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
2392 check if it is NULL and call mips_find_saved_regs if so.
2394 * remote-mips.c: Use unfiltered, not filtered, output most places.
2396 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
2397 backtrace. Revise comments.
2399 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2401 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
2402 alpha and irix. The _sigtramp case has to be handled properly
2403 in the tdep files if we have no ecoff debugging info.
2404 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
2405 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
2406 without PC_REGNUM kludge.
2407 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
2408 Clean up handling of mips sigtramp frames, improve comments.
2410 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2412 * paread.c (read_unwind_info): Fix typo.
2414 * paread.c (pa_symtab_read): Update the "check_strange_names"
2415 filter to match GCC's current output. Filter out section symbols
2416 (which the HP linker sometimes puts in the wrong place).
2418 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2420 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
2422 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
2424 * Makefile.in: Remove all references to sparcly-nat.c.
2426 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
2427 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
2428 duplicating serial.h and target.h.
2430 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
2431 are not used anywhere (a 5 Oct 1993 change removed the uses).
2433 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
2434 * config/m68k/es1800.mt: Add comment.
2435 * remote-es.c: Extensive changes to update to current conventions.
2437 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
2438 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
2439 to achieve the desired timeout.
2440 * serial.h (serial_t): Add field timeout_remaining.
2442 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2444 * c-exp.y (yylex): Reenable nested type code.
2446 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2448 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
2450 * remote-mips.c (mips_ops): Fix docstring.
2452 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
2454 * config/m68k/tm-monitor.h: Changes to bring this into accordance
2455 with the old tm-m68k-em.h:
2456 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
2457 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
2458 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
2459 Add FIXME regarding GET_LONGJMP_TARGET.
2461 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
2462 * infptrace.c (kill_inferior): Add comments.
2463 * main.c (quit_command): Call target_close after we kill or
2465 * remote-udi.c (udi_close): Don't error() if QUITTING.
2467 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
2469 * configure.in: Make m68k-coff and aout add monitor support in
2470 addition to the standard serial support.
2472 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2474 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
2477 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2479 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
2480 * elfread.c (record_minimal_symbol_and_info),
2481 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
2483 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2485 * i386-stub.c: Add ".text" right before "mem_fault:".
2487 * main.c (baud_rate): Add FIXME comment about printing -1 value.
2489 * remote-utils.c (usage): Fix message to be accurate and conform
2490 more closely to normal conventions.
2492 * remote-utils.c (gr_files_info): Have the exec_bfd test control
2493 whether to show information about exec_bfd, and not control whether
2494 to show information about device and speed.
2496 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
2497 usage message, don't dump core.
2499 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
2500 for variable size array.
2501 (bug_fetch_register, bug_store_register): Rename "value" to
2502 "fpreg_buf" because some compilers don't like variables whose
2503 names are the same as types.
2504 (bug_store_register): Use a cast when converting char * to
2507 * symmisc.c (maintenance_print_symbols): Don't refer to the name
2508 of the command in error message (the text was referring to the old
2509 name of the command).
2511 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
2513 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
2514 full details on structure elements without names. This partially
2515 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
2516 of those changes was accidental.
2518 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
2519 defined, make it an error to specify a single argument which is not
2522 * Makefile.in (version.c), main.c (print_gdb_version): Use
2523 host_alias and target_alias, not host_canonical and
2524 target_canonical, to print configuration.
2526 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2528 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
2529 of builtin_type_long. It is necessary to get a type which is
2530 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
2532 Fix many sins which will come up in 32 bit x 64 bit GDB, and
2533 various miscellaneous things discovered in the process:
2534 * printcmd.c, defs.h (print_address_numeric): New function.
2535 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
2536 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
2537 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
2538 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
2540 * utils.c, defs.h (gdb_print_address): New function.
2541 * expprint (dump_expression), gdbtypes.h: Use it.
2542 * breakpoint.c (describe_other_breakpoints),
2543 symmisc.c (dump_symtab, print_symbol):
2544 Use filtered not unfiltered I/O.
2545 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
2546 just run gdb under a debugger for this (and it had problems with
2547 printing addresses, how to print b->shadow, etc.).
2548 * buildsym.c (make_blockvector), core.c (memory_error),
2549 exec.c (print_section_info), maint.c (print_section_table),
2550 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
2551 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
2552 Add comments saying code is broken. Marked with "FIXME-32x64".
2553 * dbxread.c (process_one_symbol), partial-stab.h (default),
2554 remote-vx.c (vx_run_files_info):
2555 Don't cast int being passed to local_hex_string.
2556 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
2557 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
2559 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
2561 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
2562 * source.c: Include <sys/types.h> regardless of USG.
2564 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2566 * valops.c (value_assign): Set `type' after coercing toval.
2567 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
2568 Use extract_unsigned_integer to get the address of a reference.
2570 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2572 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
2573 AIX can use ? instead of \ for continuation. Deal with it.
2575 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
2576 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
2577 the HP compiler in ANSI mode doesn't like.
2579 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
2580 based on USG, rather than defining HAVE_SIGSETMASK to an
2581 expression containing defined. Having a macro used in #if expand
2582 to an expression containing "defined" is undefined according to
2583 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
2586 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
2588 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2589 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
2591 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
2593 * ch-exp.y (match_string_literal): Allow a zero-length string.
2594 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
2596 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2598 * i386aix-nat.c (i386_float_info): Reverse order of registers before
2599 passing them to print_387_status.
2600 (print_387_status): Don't subtract top from 7 before using it.
2601 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
2602 from 7; the above explains it.
2604 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2606 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
2607 pointer value when fixing up the frame at the start of a function.
2609 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
2611 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
2612 Sparc from the stack.
2614 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2616 * remote-mips.c (mips_initialize): Clear mips_initializing via
2617 cleanup chain, not directly.
2619 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
2620 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
2621 munging the timeout due to the limited range of c_cc[VTIME].
2623 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
2624 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
2625 m3-nat.c (m3_create_inferior): Pass it.
2626 * procfs.c: Remove ptrace function. It was declared in a way which
2627 conflicted with the prototype in unistd.h on Solaris.
2629 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2631 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
2632 in the sigcontext if it is a signal trampoline frame.
2633 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
2634 Define for Solaris2.
2636 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
2638 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
2639 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
2640 tm-sparc.h so they can be overridden if necessary.
2642 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
2644 * lynx-nat.c: Add Sparc support.
2645 * sparcly-nat.c: Remove. It's useless.
2646 * config/sparc/nm-sparclynx.h: Rewrite.
2647 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
2649 * config/sparc/tm-sparclynx.h: Rewrite.
2651 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2653 * rs6000-pinsn.c: Use the new disassembler in the opcodes
2654 directory. Old code was discarded, since the new opcode table has
2657 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
2659 * Makefile.in (realclean): Remove info files per make-stds.texi.
2661 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2663 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
2664 if N_SO_ADDRESS_MAYBE_MISSING is defined.
2665 * config/sparc/tm-sun4sol2.h: Define it.
2667 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2669 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
2670 if we did not find a symbol.
2672 Fri Jan 21 08:20:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2674 * infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
2677 * hppab-nat.c (call_ptrace): Delete redundant function.
2678 (kill_inferior, attach, detach, child_resume): Likewise.
2679 (child_xfer_memory): Likewise.
2681 * hppah-nat.c (call_ptrace): Delete redundant function.
2682 (kill_inferior, attach, detach, child_resume): Likewise.
2684 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
2686 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
2688 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
2690 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
2691 (CHILD_XFER_MEMORY): Define.
2692 (PT_*): Define so that generic infptrace.c code can be used.
2694 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2696 * xcoffread.c (xcoff_symfile_read): Make second parameter a
2697 struct section_offsets *, not a (nonexistent) struct section_offset *.
2699 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
2700 internal_xcoff_symtab, not an array of one of them. Change lots of
2701 "main_aux" to "&main_aux" and so on.
2703 * coffread.c, xcoffread.c: Include <coff/internal.h>
2706 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2708 * coffread.c (coff_getfilename): Make it not static.
2710 * xcoffread.c (read_xcoff_symtab): complain() not abort().
2712 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
2713 a completely gratuitous difference between xcoffread.c and coffread.c).
2715 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2717 * infrun.c (wait_for_inferior): Don't set frame for
2718 step_resume_breakpoint for IN_SIGTRAMP cases.
2720 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
2721 breakpoint.c (bpstat_what): Move step_resume from its own field of
2722 the struct bpstat_what into the main_action. Make it override
2723 other breakpoints. This is a conservative change in the sense
2724 that before the step resume breakpoint was a breakpoint.c
2725 breakpoint, hitting the step resume breakpoint overrode even
2726 calling bpstat_stop_status.
2728 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2730 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
2731 in case execution was stopped in the called function.
2732 * stack.c (print_frame_info, frame_info): If backtracing through
2733 a call dummy, handle the starting source line number on a line
2734 boundary like backtracing through sigtramp.
2735 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
2736 for call dummy frame right. Remove old test for dummy frame,
2737 it has been unused at least since gdb-3.5.
2738 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
2741 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

2745 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2747 * infrun.c (signals_info), target.c (target_signal_from_name):
2748 Use ugly casts to avoid enumvar < enumvar or enumvar++.
2750 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2752 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
2753 * inflow.c (terminal_ours_1): When discussing how to deal with the
2754 tty state, make note of query() as well as readline.

2757 signals for which stop and print are cleared by default.
2759 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2765 (UNWIND_ENTRY_SIZE, STUB_UNWIND_ENTRY_SIZE): New defines.
2766 * hppa-tdep.c (rp_saved): Use additional information provided
2767 by linker stub unwind descriptors.
2768 (frameless_function_invocation): Likewise.
2769 (frame_chain_valid): Likewise.
2770 * paread.c (compare_unwind_entries): New function for sorting
2771 unwind table entries.
2772 (read_unwind_info): Rewrite to remove dependency on host endianness.
2773 Read in data from the $UNWIND_END$ subspace which contains linker
2774 stub unwind descriptors. Merge that data into the basic unwind
2777 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
2779 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2781 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
2782 from either the symbol name or the auxent.
2783 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
2786 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
2788 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
2790 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2792 * README: Update notes for alpha port.
2794 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2796 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
2797 for operation fault, constraint fault, and type fault.
2799 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2801 * Makefile.in (init.c): Add comment explaining formatting conventions.
2803 * c-exp.y (parse_number): Assign to temporary between the right
2804 shifts, to work around a bug in the SCO compiler.
2806 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
2807 Add various files which were added to GDB recently.
2809 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
2812 * Makefile.in: Add mostlyclean target.
2814 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2818 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
2820 * main.c (show_commands): Make return type of extern
2821 history_get be HIST_ENTRY, rather than struct _hist_entry.
2822 (The latter loses with the upcoming merged readline.)
2824 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2826 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
2827 const char *, not char *.
2829 * symtab.h (struct symbol): Make section short, not unsigned short.
2831 * symtab.c (lookup_symbol): Add comment about QUIT here.
2833 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
2835 * c-exp.y (parse_number): Check for overflow regardless of range
2836 checking. Fix overflow check to use unsigned LONGEST, not
2839 * c-exp.y (parse_number): Make it so that integer constants are
2840 builtin_type_long_long if builtin_type_long isn't big enough or if
2841 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
2843 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
2844 Print our "()" first, then recurse for the target type.
2846 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2848 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
2850 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
2852 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2854 * utils.c (request_quit): Re-establish signal handler regardless
2857 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
2859 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2861 * i960-tdep.c: Include target.h.
2863 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
2865 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
2867 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2869 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
2870 changes (status -> ourstatus; declare status, etc.).
2871 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
2873 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2875 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
2877 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2879 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
2881 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2883 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
2885 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2887 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
2889 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2891 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
2892 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
2894 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
2897 Add search to target vector (#if 0'd until after 4.12):
2898 * target.h (to_search, target_search): Add.
2899 * gdbcore.h, core.c (generic_search): Add.
2900 * remote.c (remote_search): Add.
2901 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
2904 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
2905 is on, call find_pc_function rather than relying just on the minimal
2906 symbols (probably only matters for symbol readers which don't put
2907 statics in the minimal symbols, but changing this strikes me as
2908 not conservative enough).
2909 Initialize name_location in all cases.
2910 If no symbol and no msymbol, don't print anything symbolic.
2912 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2914 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2916 * printcmd.c (print_address_symbolic): Make it search the
2917 symtabs for variables as well as functions. Add `set print
2918 fast-symbolic-addr' and default it to fast (the old way).
2919 Print line numbers for data items as well as functions.
2921 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2922 address, if a symbol is found (take two more args pointing to
2923 where to store these results).
2925 * symtab.h (find_addr_symbol): Add prototype.
2927 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2929 * objfiles.h: Fix comments to reflect the fact that the phrase
2930 "top of stack" always refers to where the pushing and popping takes
2931 place, regardless of whether it is at the highest or lowest address.
2933 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2935 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2936 compiler generated tag names.
2937 * mdebugread.c (parse_type): Handle cross references to qualified
2939 * valops.c (value_struct_elt): Improve error message if the
2940 address of a method is requested from an object instance.
2941 * valops.c (search_struct_method): Make name_matched non-static
2942 to get it initialized correctly.
2943 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
2944 exclude segment register which are not writable on newer SCO versions.
2946 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2948 * go32-xdep.c: Remove unused function uerror.
2949 (sigsetmask): Declare return type. Declare argument (to match the
2950 way it is called). Explicitly return 0.
2952 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
2954 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
2955 partial_symbol): Shrink the storage sizes of symbols, by making
2956 enums into 1-byte bitfields when compiled __GNUC__, moving all the
2957 enums and small ints to the end of each struct to improve
2958 alignment, and switching the section number from int to unsigned
2961 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
2963 * symtab.c (find_addr_symbol): New routine that will find the nearest
2964 symbol associated with an address. It does so by exhaustive
2965 search of the symtabs, so it's slow but complete.
2967 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
2969 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
2970 to [0,0] rather than [0, end of first source file]. This avoids
2971 problems with other parts of GDB looking for linetables in the
2972 _globals_ symtab. Eliminate variables num_object_files and
2973 first_object_file_end.
2975 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2977 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
2978 (pop_frame): Restore PC2 and LR0 from dummy frames.
2979 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
2980 (setup_arbitrary_frame): Handle 3 args and set up real frames.
2981 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
2982 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
2983 (SETUP_ARBITRARY_FRAME): Define.
2985 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2987 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
2989 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2991 * remote-udi.c (udi_resume): Correct prototype.
2993 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2995 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
2996 hppa_frame_find_saved_regs.
2997 * hppa-tdep.c (dig_fp_from_stack): Delete function.
2998 (prologue_inst_adjust_sp): New function.
2999 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
3000 (skip_prologue): Completely rewrite to use unwind information.
3001 (hppa_frame_find_saved_regs): Likewise.
3003 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3005 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
3006 to convert a signal number with appropriate bounds checking.
3008 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
3010 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3012 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
3013 print a newline to end the display anyway.
3015 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
3016 coprocessor status regs) when popping a frame. This fixes
3017 float exceptions that occur after calling inferior functions.
3019 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
3020 Read and write the fsr (float status register) to/from the child
3021 process along with the float regs. Remove Peter Schauer's change
3022 of May 24 '93, which has higher overhead and doesn't solve the
3023 real problem (which was that FSR wasn't being set).
3025 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
3027 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
3028 stack overflow check isn't right after the register stack
3029 adjustment instruction. Metaware R2.3u compiler moves other
3030 things in front of it. This fix isn't perfect but is what's
3033 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3035 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
3037 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
3038 character filenames.
3039 * configure.in: Change accordingly.
3041 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
3043 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
3044 _filtered io routines from these two files.
3046 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3048 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
3049 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
3050 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
3052 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
3054 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3056 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
3057 printing to gdb_stderr.
3059 * remote-udi.c (udi_kill): Don't close the connection, just set
3060 inferior_pid to zero.
3061 (udi_mourn): Call remove_breakpoints.
3063 * remote-udi.c: Remove obsolete need_artificial_traps comment.
3065 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
3067 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3069 * symtab.c (lookup_symbol): Don't try adding .c to the name.
3071 * remote-bug.c: At the start of each section, reset srec_frame
3074 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
3075 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
3076 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
3077 code which looks for those two waitkinds. Use switch statement.
3078 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
3079 CHILD_SPECIAL_WAITSTATUS.
3081 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
3082 * Move target_signal_from_host, target_signal_to_host, and
3083 store_waitstatus from inftarg.c to target.c. procfs needs them.
3084 * target.c: Include "wait.h" and <signal.h>.
3085 * target.h, infrun.c (proceed), proceed callers: Pass new code
3086 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
3087 enums being treated as unsigned and is cleaner.
3088 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
3090 * infcmd.c (signal_command), infrun.c (signals_info):
3091 Don't allow user to specify numeric equivalent of
3092 TARGET_SIGNAL_DEFAULT.
3094 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
3096 * config/alpha/alpha-netware.mt: New target support for Alpha
3098 * configure.in: Add alpha-*-netware* target.

3102 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
3104 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3106 * target.h: Add enum target_waitkind, enum target_signal, and
3107 struct target_waitstatus. Change status argument to target_wait to
3108 be struct target_waitstatus * instead of int *.
3109 * target.h, infrun.c, all targets: Change type of signal arguments
3110 to resume(), proceed(), and target_resume() from int to enum
3112 * All targets (*_wait, *_resume): Change accordingly.
3113 * infcmd.c (program_info, signal_command), throughout infrun.c,
3114 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
3115 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
3116 signal code stuff right with the new signals would be non-trivial).
3117 * inferior.h (stop_signal): Make it enum target_signal not int.
3118 * target.c, target.h (target_signal_to_string, target_signal_to_name,
3119 target_signal_from_name): New functions.
3120 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
3121 store_waitstatus): New functions.
3122 * procfs.c (procfs_notice_signals): Use them.
3123 * i960-tdep.c (i960_fault_to_signal): New function, to replace
3125 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
3127 * objfiles.c (build_objfile_section_table): Don't abort() if
3128 objfile->sections is already set.
3130 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
3131 to match recent change to exec.c.
3135 * main.c (print_gdb_version): Change year to 1994.
3137 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
3138 * Makefile.in (NONSRC): Add ChangeLog-93.
3140 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3142 * stabsread.c (read_type): Allow defining several type numbers
3143 at once (e.g. "(1,2)=(3,4)="...).
3145 * stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
3147 * breakpoint.c (frame_in_dummy): Check PC as well as frame.
3149 Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)

3152 to process_one_symbol.
3153 * symtab.c (find_pc_psymbol): Search global_psymbols as well to
3154 avoid caching a bad endaddr in find_pc_partial_function.
3156 Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3158 * config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
