1379 (set_demangling_style, set_demangling_command): Use savestring not
1380 strdup. We were not dealing properly with a NULL return from

1394 Fri Mar 25 10:14:03 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1396 * hppa-tdep.c (skip_prologue): Do nothing if not at the beginning
1398 (skip_trampoline_code): Rewrite and add support for argument

1403 if no unwind descriptor is found.
1405 * tm-hppa.h (NUM_REGS): Bump to 128 registers.
1406 (REGISTER_NAMES): Add entries for "right-half" of FP registers.
1407 (REGISTER_RAW_SIZE, MAX_REGISTER_RAW_SIZE): Do not treat FP regs
1408 differently. All registers are four bytes.
1409 (REGISTER_BYTES, REGISTER_BYTE): Simplify now that all registers are
1411 (REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.
1413 * hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
1414 registers as both single and double values (fetching 2nd 32bit half
1415 as necessary). Annotate each register printed with its precision.
1417 * paread.c (read_unwind_info): Fix off-by-one error.

1425 * config/mips/tm-mips.h (SETUP_ARBITRARY_FRAME): Revise comment
1426 regarding using the PC--using the PC is necessary and all the
1427 FIXME comments in the world won't make it go away.
1429 * valops.c (value_at, value_at_lazy): Give error if we dereference
1431 * gdbtypes.h: Fix comments regarding TYPE_CODE_VOID.
1432 * stabsread.c: Use 1, not 0, for TYPE_LENGTH of void types.
1434 * stabsread.c (patch_block_stabs): Add comment about what happens
1435 if the definition is in another compilation unit from the stab.
1437 * dbxread.c (end_psymtab): Add comment about empty psymtabs.
1439 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1441 * main.c (complete_command): New command, from Rick Sladkey
1442 <jrs@world.std.com>.
1443 (symbol_completion_function): Don't declare rl_point and
1444 rl_line_buffer; they are now declared in readline.h.
1445 (show_commands): Don't declare history_base; it is declared in
1447 * command.c (lookup_cmd): Don't delete trailing whitespace.
1448 Reverts change of 14 May 1989.
1450 Wed Mar 23 16:14:52 1994 Stu Grossman (grossman at cygnus.com)
1452 * minsyms.c (prim_record_minimal_symbol): Move section deduction
1453 code from prim_record_minimal_symbol_and_info() to here. Callers
1454 of the latter can legitimately supply a section number of -1.
1456 Wed Mar 23 07:50:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1458 * gdbtypes.h, gdbtypes.c: Add comments regarding whether static
1459 member functions have an element in args for a (nonexistent) this
1462 Tue Mar 22 20:12:53 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
1464 * config/pa/tm-hppao.h (NO_PC_SPACE_QUEUE_RESTORE): Define.

1467 queue if NO_PC_SPACE_QUEUE_RESTORE is defined.
1469 * stabsread.c (REG_STRUCT_HAS_ADDR): Accept additional argument
1470 for the structure's type. All callers changed.
1472 * valops.c (call_function_by_hand): Check REG_STRUCT_HAS_ADDR
1473 for each structure argument rather than assuming it's either
1474 true or false for all structure arguments.
1476 * config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
1477 on the length structure passed, not the compiler used.
1479 * config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
1480 argument for the structure's type.
1482 Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1484 * values.c (set_internalvar): Don't set var->value until we are

1492 * symmisc.c (maintenance_check_symtabs): New function to check
1493 consistency of psymtabs and symtabs.
1494 * symtab.h (maintenance_check_symtabs): Add prototype.
1495 * maint.c: Add new `maint check-symtabs' command.
1496 * config/i386/tm-i386aix.h, config/i386/tm-sun386.h,
1497 config/i386/tm-symmetry.h (REGISTER_CONVERT_TO_RAW): Fix typo.

1502 * config/i386/xm-symmetry.h: Add missing #endif.
1503 * config/i386/nm-symmetry.h (NO_PTRACE_H): Add for Dynix.
1504 * config/i386/symmetry.mt (TDEPFILES): Add i386-tdep.o.
1505 * config/i386/symmetry.mh (NAT_FILE, NATDEPFILES): Add.

1509 * hppa-tdep.c (hppa_fix_call_dummy): Use value_ptr.
1510 (hppa_push_arguments): Likewise.
1512 Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
1514 * alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
1515 improve remote debugging efficiency. Also fixed problems with
1516 doing function calls for programs with no entry points.
1517 * infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
1518 entry_point_address.
1519 * inferior.h (PC_IN_CALL_DUMMY): ditto.
1520 * mdebugread.c (parse_symbol, parse_procedure, parse_external,
1521 parse_lines): Pass section_offsets info to these routines so that
1522 we can relocate symbol table entries upon readin.
1523 * (psymtab_to_symtab_1): Set symtab->primary to tell
1524 objfile_relocate to do relocations for our symbols.
1525 * (ecoff_relocate_efi): New routine to relocate adr field of PDRs
1526 (which hang off of the symbol table).
1527 * Use prim_record_minimal_symbols_and_info instead of
1528 prim_record_minimal_symbols to supply section info to make minimal
1529 symbol relocations work.
1530 * minsyms.c (prim_record_minimal_symbols_and_info): If section is
1531 -1, try to deduce it from ms_type.
1532 * objfiles.c (objfile_relocate): Use ALL_OBJFILE_SYMTABS where
1533 appropriate. Handle relocation of MIPS_EFI symbols special. Also,
1534 add code to relocate objfile->sections data structure.
1535 * remote.c (get_offsets): Use new protocol message to acquire
1536 section offsets from the target.
1537 * (remote_wait): Get rid of relocation stuff. That's all handled
1538 by objfile_relocate now.
1539 * config/alpha/alpha-nw.mt (TM_FILE): Use tm-alphanw.h.
1540 * config/alpha/tm-alpha.h: Define CALL_DUMMY_ADDRESS, and
1542 * config/alpha/tm-alphanw.h: DECR_PC_AFTER_BREAK=0, VM_MIN_ADDRESS=0.
1544 Sun Mar 20 15:21:57 1994 Doug Evans (dje@cygnus.com)
1546 * sparc-tdep.c (sparc_frame_find_save_regs): Use REGISTER_RAW_SIZE
1548 * sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
1549 can no longer set this at run time.
1550 * config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
1551 (TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
1552 * config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
1553 sparc-tdep.c compiles).
1554 (TARGET_PTR_BIT): Must be a constant now, fix at 64.
1556 Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1558 * config/m68k/{cisco.mt,tm-cisco.h}: New files.
1559 * Makefile.in (ALLPARAM, ALLCONFIG): Add them.
1560 * configure.in: Recognize m68*-cisco*-*.
1562 * Makefile.in (TAGS): Use variables directly, rather than using
1563 find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
1564 and means that these filenames no longer need be unique across all
1565 the config/* directories.
1566 * configure.in: Put the config/*/ into TM_FILE, etc.
1568 * m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
1569 and trapv exceptions.
1571 * target.h (struct section_table), objfiles.h (struct obj_section):
1572 Change name of field sec_ptr to the_bfd_section. More mnemonic
1573 and avoids the (sort of, for the ptx compiler) name clash with
1574 the name of the typedef.
1575 * exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
1576 solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.
1578 * utils.c: Include readline.h.
1579 * Makefile.in (utils.o): Add dependency.
1581 * remote.c (getpkt): Add support for run-length encoding.
1583 Fri Mar 18 19:11:15 1994 Steve Chamberlain (sac@jonny.cygnus.com)
1585 * utils.c (prompt_for_continue): Call readline, not gdb_readline.
1587 Fri Mar 18 10:25:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1589 * dstread.c (record_minimal_symbol): New arg objfile. Pass it to
1590 prim_record_minimal_symbol.
1593 * regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
1594 computing their offset from the start of the old buffer and adding
1595 to the new buffer, rather than by assuming we can add the
1596 difference between the old buffer and the new buffer (it might not
1597 fit in an int). Merge in cosmetic differences from emacs regex.c
1598 version of this macro.
1600 Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
1602 * Makefile.in (install-only): Fix use of program_transform_name.
1604 Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1606 * printcmd.c: Remove "set print fast-symbolic-addr off" command.
1607 The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
1608 so I'm nuking the command.
1609 * symtab.c (find_addr_symbol): Comment out, no longer used.
1611 * main.c (main): Don't init_source_path for the -cd argument. Now
1612 that source_path doesn't contain the current_directory from when
1613 GDB started up, init_source_path is no longer useful (and is
1614 harmful because it clobbers a source_path set in $HOME/.gdbinit).
1616 * TODO: Remove item about line numbers being off. It is useless
1617 and confusing without a reproducible test case (it mentions
1618 proceed(), but I was able to step through proceed without trouble).
1620 Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1622 For Sunos 4.x targets, enable gdb to set breakpoints in shared
1623 library functions before the executable is run. Retrieve dynamic
1624 symbols from stripped executables.
1625 * symtab.h (minimal_symbol_type): Add mst_solib_trampoline type.
1626 * parse.c (write_exp_msymbol), symmisc.c (dump_msymbols),
1627 symtab.c (list_symbols): Handle mst_solib_trampoline.
1628 * minsyms.c (lookup_minimal_symbol): Handle mst_solib_trampoline
1629 for all targets, remove IBM6000_TARGET dependencies.
1630 * dbxread.c (read_dbx_dynamic_symtab): New function.
1631 * dbxread.c (dbx_symfile_read): Use it.
1632 * dbxread.c (SET_NAMESTRING): Set namestring to
1633 "<bad string table index>" instead of "foo" if the string index is
1635 * xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
1637 * symtab.c (list_symbols): Take from_tty as parameter and pass it
1638 to break_command. Handle mst_file_* minimal symbol types.
1639 * config/i386/tm-i386bsd.h: Give just macro name, not args, to #undef.
1641 Tue Mar 15 11:40:43 1994 Kung Hsu (kung@mexican.cygnus.com)
1643 * c-exp.y(yylex): fix potential memory overflow.
1645 Tue Mar 15 10:33:28 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1647 * environ.c (set_in_environ): Eliminate special handling of PATH and
1649 * putenv.c: Removed, conflicts with system declaration of
1650 putenv on RS/6000 running AIX 3.2.5, and above change makes it
1652 * Makefile.in: Change accordingly.
1653 * procfs.c (procfs_create_inferior): Change comment accordingly.
1655 Tue Mar 15 10:05:27 1994 Jim Kingdon (kingdon@cygnus.com)
1657 * rs6000-tdep.c: Change value to value_ptr.
1659 Sun Mar 13 09:45:51 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1661 * i386m3-nat.c: Include floatformat.h.
1662 (get_i387_state): Use memset not bzero.
1666 * Makefile.in: Enable commented out getopt_h, bfd_h, etc. Change
1667 ieee-float.h to floatformat.h.
1669 * valprint.c (val_print_string): Ignore error if the error
1670 happened after a terminating '\0'.
1672 * c-valprint.c (c_val_print): Never add 1 to return value from
1673 val_print_string; just return what it returns.
1675 * target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
1676 looping through all of the enums.
1677 * infrun.c (signals_info): Use it.
1679 Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1681 * main.c (main): When printing warning about bad baud rate, don't
1682 use warning(); it relies on current_target which isn't set up yet.
1684 * breakpoint.c (_initialize_breakpoint): Update docstring for
1685 tbreak to match what the code actually does. Don't mention tbreak
1686 in docstrings for "enable once" or "enable breakpoints once".
1688 Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1690 * symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
1691 while (0). That defeats the whole purpose of using do . . . while (0).
1692 * mdebugread.c (parse_partial_symbols): Don't use ?: expression as
1693 list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
1694 using a ?: expression as an lvalue is not portable.
1696 * stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
1697 convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
1698 'p' and 'r' symbol descriptors into a single symbol to look for a
1700 * README, config/sparc/tm-sparc.h: Update comments.
1702 Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1704 * mdebugread.c (parse_type): Do not complain for types with
1705 an `indexNil' aux index, these are simply undefined types.
1706 Remove indexNil check from caller of parse_type.
1707 * mdebugread.c (parse_partial_symbols): Do not enter
1708 stGlobal, scCommon symbols into the minimal symbol table, their
1709 value is the size of the common, not its address.
1710 Handle scInit, scFini, scPData and scXData sections.
1711 Use minimal symbol type mst_file_* for stLabel symbols, instead of
1713 Enter stProc symbols into the global_psymbols list once, not into
1714 the static_psymbols_list.
1715 Get rid of dummy psymtab if it is empty, to allow proper detection
1716 of stripped executables.
1717 * mdebugread.c (cross_ref): Allow cross references to Fortran
1720 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1722 * stabsread.c (common_block_end, fix_common_block): Stash the
1723 struct pending * in the SYMBOL_TYPE, not the SYMBOL_NAMESPACE, so
1724 as to not assume that a pointer fits in an enum.
1726 Wed Mar 9 18:56:36 1994 Kung Hsu (kung@mexican.cygnus.com)
1728 * os9kread.c (fill_sym): check compiler verion number for pre-
1730 * os9kread.c (os9k_process_one_symbol): address of symbol is
1731 relative to section not module.
1732 * stabsread.c (define_symbol): add symbol type 's' as local
1734 * remote-os9k.c: add command 'set monitor_log' to turn on or off
1736 * remote-os9k.c: fix bug in delete breakpoint, single step trace.
1737 * remote-os9k.c: fix bug in 'set remotebaud' function.
1738 * remote-os9k.c (rombug_link): minimize checking so to improve
1740 * symfile.c (symbol_file_command): check if failed to link, also make
1741 the command be able to accept more than one filenames.
1742 * target.c (target_link): check if failed to link with rombug.
1743 * config/i386/tm-i386os9k.h : add #define DECR_PC_AFTER_BREAK 0.
1745 Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
1747 * remote-es.c (es1800_child_ops): Don't declare it static.

1755 * dbxread.c: New variable lowest_text_address.
1756 (record_minimal_symbol, read_dbx_symtab): Set it.
1757 (read_dbx_symtab): Use lowest_text_address + text_size instead of
1758 end_of_text_address.
1759 * config/gould/tm-pn.h: Add comment regarding END_OF_TEXT_DEFAULT.
1761 * dbxread.c (end_psymtab): Remove old and commented out
1762 capping_global and capping_static. Fix comments regarding
1763 N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.
1765 * parser-defs.h: Add "extern" to start of variable declarations so
1766 we don't end up with commons.
1767 * parse.c: Define these variables.
1769 * irix5-nat.c (find_solib): Cast o_path to CORE_ADDR when using it
1772 Mon Mar 7 13:00:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

1776 Sun Mar 6 17:36:53 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
1778 * solib.c (elf_locate_base): New function to locate the address
1779 of the dynamic linker's runtime structure in the dynamic info section.
1780 * solib.c (locate_base): Use it instead of iterating over the list
1781 of mapped address segments.
1782 * solib.c (look_for_base, bfd_lookup_symbol): Removed, no longer
1785 Fri Mar 4 09:50:47 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

1804 * ch-exp.y (match_simple_name_string): Accept '_' as well as an
1805 alphabetic character as the start of a name.
1807 * sparclite/Makefile.in (all install): Build and install aload.
1809 * configure.in: Accept i[34]86-*-*sysv32 because that is what
1810 config.guess and config.sub produce.
1812 * mips-tdep.c: Change value to value_ptr.
1814 Wed Mar 2 09:17:55 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
1816 * breakpoint.c, breakpoint.h, c-valprint.c, ch-valprint.c,
1817 cp-valprint.c, eval.c, expprint.c, findvar.c, language.c,

1903 files. Also call target_link() to get relocation infos.
1904 * target.c (target_link): new function to get relocation info when
1905 a symbol file is requested to load.
1906 * main.c (quit_command): take out 'inferior_pid != 0' condition,

1949 just print the error message rather than calling error(). Don't
1950 access *(bufptr-1) if bufptr points to the start of the buffer.
1951 When looking for '\0', don't increment bufptr and addr if bufptr
1952 started out already at limit. If an error happens on fetching the
1953 first character, don't print the string.

1992 * breakpoint.c (bpstat_what): Return BPSTAT_WHAT_THROUGH_SIGTRAMP
1993 if we hit a bp_through_sigtramp breakpoint. Remove kludge which
1994 ignored bs->stop for a bp_step_resume breakpoint.
1995 * infrun.c (wait_for_inferior): Make a through_sigtramp_breakpoint
1996 which performs one (the check_sigtramp2 one) of the functions
1997 which had been handled by the step_resume_breakpoint. For each
1998 use of the step_resume_breakpoint, make it still use the
1999 step_resume_breakpoint, use the through_sigtramp_breakpoint, or
2001 Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
2002 When setting the frame address of the step resume breakpoint, set
2003 it to the address for frame *before* the call instruction is
2004 executed, not after.
2006 * mips-tdep.c (mips_print_register): Print integers using
2007 print_scalar_formatted rather than duplicating all the

2009 (mips_push_dummy_frame): Use read_register_gen rather than using
2010 read_register and then putting it back in target format with
2011 store_unsigned_integer. If registers are more than 4 bytes, give
2012 an error rather than have some registers overwrite other
2014 #if 0 unused include of opcode/mips.h.
2016 * symfile.h: Don't declare arguments for coff_getfilename.
2018 * defs.h: Revert Kung change regarding FORCE_LONG_LONG.

2067 set up the global offset table pointer in pic compiled code.
2068 * config/mips/tm-mips.h (FIX_CALL_DUMMY): For big endian targets,
2069 error() on TYPE_CODE_FLT arguments whose size is greater than 8,
2070 swap all other TYPE_CODE_FLT arguments as mips_push_arguments
2071 ensures that floats are promoted to doubles before they are pushed

2076 * sparclite/Makefile.in, sparclite/salib.c, sparclite/sparclite.h:
2077 Fixup cache_on and flush_i_cache so that they work for both the
2078 930 and 932 processors. Rewrite most low level funcs (uart
2079 access & cache stuff) to use new ASI access macros in sparclite.h.
2080 Also make it easy to access second serial port.

2201 try to call UDIDisconnect again. Print better message.
2202 (udi_kill): Just call UDIDisconnect ourselves, rather than doing
2204 (udi_create_inferior): If udi_session_id is negative, open a new
2205 TIP rather than giving an error.

2225 * corelow.c (solib_add_stub, core_open): Pass address of from_tty
2226 rather than trying to shove an int into a pointer and back out
2227 again. This avoids compiler warnings.
2229 * defs.h (alloca): Declare as void *, not char *, on hpux.
2230 Don't prototype it, just declare the return type.

2244 * i386-tdep.c (i386_extract_return_value): Pass TYPE_LENGTH (type)
2245 to store_floating, not nonexistent variable len.
2247 * remote-mips.c (mips_insert_breakpoint, mips_remove_breakpoint):
2249 (mips_store_word): Change calling convention to return errors, and
2250 to provide old contents if the caller wants it.
2251 (mips_xfer_memory): Deal with errors from mips_store_word.
2252 * config/mips/tm-idt.h, config/mips/tm-idtl.h: Remove BREAKPOINT
2253 define now that remote-mips.c doesn't use BREAKPOINT.
2255 * remote-mips.c (mips_create_inferior): Call warning if arguments
2256 specified, and then execute "set args" command. Call error, not
2257 mips_error, if executable file not specified.
2259 * remote-e7000.c: Replace "snoop" command (e7000_noecho) with
2262 * config/rs6000/tm-rs6000.h (STORE_STRUCT_RETURN): Don't cast
2265 Sat Feb 5 05:27:05 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2267 * value.h (print_longest): Rename "value" to "val" in prototype
2268 declaration because some compilers don't like arguments whose
2269 names are the same as types.
2270 * remote.c (remote_xfer_memory): Cast "myaddr" to unsigned char *
2271 before passing it to remote_*_bytes.
2273 Fri Feb 4 15:53:18 1994 Steve Chamberlain (sac@cygnus.com)
2275 * h8500-tdep.c (saved_pc_after_call): The size of the
2276 pc is memory model dependent. (segmented_command,
2277 unsegmented_command, _initialize_h8500_tdep): New commands to
2278 change memory model.
2279 * remote-e7000.c (_initialize_remote_e7000): Change name of snoop
2281 * remote-hms.c (hms_load): Remove breakpoints when loaded.
2282 (hms_wait): Use new status structure
2283 (hms_open): Push the target here. (hms_before_main_loop): Not
2284 here. (supply_val, hms_fetch_register, hms_store_register): Cope
2285 with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
2286 * sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
2287 all registers in a compact way.
2289 Fri Feb 4 07:41:13 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2291 * config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
2292 as CORE_ADDR to match definition in rs6000-tdep.c.
2294 Fri Feb 4 01:14:20 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2296 * dwarfread.c (process_dies): Skip nested TAG_compile_unit DIEs.
2297 * dwarfread.c (add_partial_symbol): Do not enter opaque aggregate
2298 definitions into the psymtab.
2300 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2302 * m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
2303 a special exceptionSize for the 68332.
2305 * remote-udi.c (udi_attach): If no arguments, print error.
2307 Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
2309 * Makefile.in (VERSION): Bump to 4.12.1
2310 * NEWS, README: Update to match 4.12 release.
2312 Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2314 * command.c (empty_sfunc): New function.
2315 (add_set_cmd): Use it instead of not_just_help_class_command.
2316 (not_just_help_class_command): Change calling convention back to
2317 what it was before yesterday's change.
2319 * stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
2320 of the type if present.
2322 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2324 * printcmd.c (decode_format): Don't blithely set the size for
2325 an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
2327 * defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
2328 If BFD64, make a LONGEST a BFD_HOST_64_BIT.
2329 * defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
2330 always just check against INT_MIN and INT_MAX (this also fixes things
2331 if sizeof (long) > sizeof (int), e.g. Alpha).
2332 * config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
2333 Don't define LONGEST or BUILTIN_TYPE_LONGEST.
2334 * gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
2335 BUILTIN_TYPE_UNSIGNED_LONGEST.
2336 * language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
2337 longest_int and longest_unsigned_int.
2338 * value.h (struct value): Just align to LONGEST, rather than worrying
2339 about CC_HAS_LONG_LONG.
2340 * valarith.c (value_binop): Figure out type ourself based on
2341 sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
2342 point is that we don't depend on CC_HAS_LONG_LONG anymore.
2343 * valprint.c (val_print_type_code_int): Just call
2344 extract_unsigned_integer directly, rather than going through
2346 * printcmd.c (decode_format): Remove code which would sometimes
2347 change 'g' size to 'w' for integers. print_scalar_formatted handles
2348 printing huge integers well enough, thank you.
2350 * command.c (add_set_cmd, not_just_help_class_command): Change
2351 to make this the sfunc, not cfunc, since that is how we call it.
2352 * command.h: Comment difference between sfunc and cfunc.
2353 * demangle.c (set_demangling_command): Add third arg since that
2354 is how it is called.
2355 (_initialize_demangler): Use sfunc, not cfunc, for
2356 set_demangling_command, since that is how it is called.
2357 Remove show_demangling_command; it has no effect.
2359 * command.c (shell_escape): Report errors correctly (with error
2360 message from strerror).
2362 Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2364 * xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
2365 x_scnlen.l rather than x_scnlen to match corresponding change in
2368 Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2370 * gdbtypes.h, ch-typeprint.c, ch-valprint.c:
2371 Change comments regarding TYPE_CODE_BOOL.
2372 * language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
2373 regardless of the language.
2374 (value_true): Just call value_logical_not regardless of language.
2375 * coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
2376 Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
2377 * language.h: Improve comment for la_builtin_type_vector.
2378 * m2-lang.c (_initialize_m2_language): Don't add any fields to
2379 builtin_type_m2_bool.
2381 Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
2383 * config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
2384 Define IN_SIGTRAMP and backtrace correctly through signal handlers.
2386 Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2388 * procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
2389 by restarting the ioctl.
2391 Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2393 * target.h (target_wait): Add comment about calling
2394 return_to_top_level.
2396 Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2398 * coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
2399 additional arguments.
2400 * xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
2402 Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
2404 * sparc-stub.c: Remove unnecessary #include of memory.h.
2406 Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2408 * mips-tdep.c: Remove code which sets saved_regs from
2409 init_extra_frame_info and put it in new function mips_find_saved_regs.
2410 (READ_FRAME_REG): Remove macro and replace uses with the expansion.
2411 * mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
2412 check if it is NULL and call mips_find_saved_regs if so.
2414 * remote-mips.c: Use unfiltered, not filtered, output most places.
2416 * blockframe.c (get_prev_frame_info): Detect and stop an infinite
2417 backtrace. Revise comments.
2419 Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2421 * mdebugread.c (parse_procedure): Remove _sigtramp kludges for
2422 alpha and irix. The _sigtramp case has to be handled properly
2423 in the tdep files if we have no ecoff debugging info.
2424 * alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
2425 mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
2426 without PC_REGNUM kludge.
2427 * mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
2428 Clean up handling of mips sigtramp frames, improve comments.
2430 Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
2432 * paread.c (read_unwind_info): Fix typo.
2434 * paread.c (pa_symtab_read): Update the "check_strange_names"
2435 filter to match GCC's current output. Filter out section symbols
2436 (which the HP linker sometimes puts in the wrong place).
2438 Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2440 * serial.h (SERIAL_SET_TTY_STATE): Comment return value.
2442 * Makefile.in (TAGS): Just echo one line, rather than the whole thing.
2444 * Makefile.in: Remove all references to sparcly-nat.c.
2446 * Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
2447 remote-sim.h directly, rather than via $(remote_utils_h). This avoids
2448 duplicating serial.h and target.h.
2450 * Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
2451 are not used anywhere (a 5 Oct 1993 change removed the uses).
2453 * config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
2454 * config/m68k/es1800.mt: Add comment.
2455 * remote-es.c: Extensive changes to update to current conventions.
2457 * ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
2458 If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
2459 to achieve the desired timeout.
2460 * serial.h (serial_t): Add field timeout_remaining.
2462 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2464 * c-exp.y (yylex): Reenable nested type code.
2466 Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2468 * a29k-tdep.c (examine_tag): Add comment regarding argcount.
2470 * remote-mips.c (mips_ops): Fix docstring.
2472 * remote-bug.c (bug_ops): Remove spurious newline from docstring.
2474 * config/m68k/tm-monitor.h: Changes to bring this into accordance
2475 with the old tm-m68k-em.h:
2476 (GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
2477 (HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
2478 (REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
2479 Add FIXME regarding GET_LONGJMP_TARGET.
2481 * remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
2482 * infptrace.c (kill_inferior): Add comments.
2483 * main.c (quit_command): Call target_close after we kill or
2485 * remote-udi.c (udi_close): Don't error() if QUITTING.
2487 Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
2489 * configure.in: Make m68k-coff and aout add monitor support in
2490 addition to the standard serial support.
2492 Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2494 * mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
2497 Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2499 * config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
2500 * elfread.c (record_minimal_symbol_and_info),
2501 dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
2503 Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2505 * i386-stub.c: Add ".text" right before "mem_fault:".
2507 * main.c (baud_rate): Add FIXME comment about printing -1 value.
2509 * remote-utils.c (usage): Fix message to be accurate and conform
2510 more closely to normal conventions.
2512 * remote-utils.c (gr_files_info): Have the exec_bfd test control
2513 whether to show information about exec_bfd, and not control whether
2514 to show information about device and speed.
2516 * remote-utils.c (gr_open): If sr_get_device returns NULL, give
2517 usage message, don't dump core.
2519 * remote-bug.c (bug_write_memory): Use alloca, not GCC extension
2520 for variable size array.
2521 (bug_fetch_register, bug_store_register): Rename "value" to
2522 "fpreg_buf" because some compilers don't like variables whose
2523 names are the same as types.
2524 (bug_store_register): Use a cast when converting char * to
2527 * symmisc.c (maintenance_print_symbols): Don't refer to the name
2528 of the command in error message (the text was referring to the old
2529 name of the command).
2531 * symmisc.c (dump_symtab): Fix args to fprintf_filtered.
2533 * c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
2534 full details on structure elements without names. This partially
2535 reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
2536 of those changes was accidental.
2538 * stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
2539 defined, make it an error to specify a single argument which is not
2542 * Makefile.in (version.c), main.c (print_gdb_version): Use
2543 host_alias and target_alias, not host_canonical and
2544 target_canonical, to print configuration.
2546 Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2548 * parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
2549 of builtin_type_long. It is necessary to get a type which is
2550 TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
2552 Fix many sins which will come up in 32 bit x 64 bit GDB, and
2553 various miscellaneous things discovered in the process:
2554 * printcmd.c, defs.h (print_address_numeric): New function.
2555 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
2556 breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
2557 cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
2558 printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
2560 * utils.c, defs.h (gdb_print_address): New function.
2561 * expprint (dump_expression), gdbtypes.h: Use it.
2562 * breakpoint.c (describe_other_breakpoints),
2563 symmisc.c (dump_symtab, print_symbol):
2564 Use filtered not unfiltered I/O.
2565 (remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
2566 just run gdb under a debugger for this (and it had problems with
2567 printing addresses, how to print b->shadow, etc.).
2568 * buildsym.c (make_blockvector), core.c (memory_error),
2569 exec.c (print_section_info), maint.c (print_section_table),
2570 mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
2571 symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
2572 Add comments saying code is broken. Marked with "FIXME-32x64".
2573 * dbxread.c (process_one_symbol), partial-stab.h (default),
2574 remote-vx.c (vx_run_files_info):
2575 Don't cast int being passed to local_hex_string.
2576 * symmisc.c (print_symbol): Don't cast long being passed to %lx.
2577 * symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
2579 * symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
2581 * printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
2582 * source.c: Include <sys/types.h> regardless of USG.
2584 Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2586 * valops.c (value_assign): Set `type' after coercing toval.
2587 * c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
2588 Use extract_unsigned_integer to get the address of a reference.
2590 Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2592 * stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
2593 AIX can use ? instead of \ for continuation. Deal with it.
2595 * paread.c (read_unwind_info): Just assign to objfile->obj_private,
2596 not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
2597 the HP compiler in ANSI mode doesn't like.
2599 * main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
2600 based on USG, rather than defining HAVE_SIGSETMASK to an
2601 expression containing defined. Having a macro used in #if expand
2602 to an expression containing "defined" is undefined according to
2603 ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
2606 Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
2608 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
2609 Clean up the changes of 11 Jan, as recommended by Peter Schauer.
2611 Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
2613 * ch-exp.y (match_string_literal): Allow a zero-length string.
2614 * ch-lang.c (chill_printstr): Don't print zero-length string funny.
2616 Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2618 * i386aix-nat.c (i386_float_info): Reverse order of registers before
2619 passing them to print_387_status.
2620 (print_387_status): Don't subtract top from 7 before using it.
2621 * i387-tdep.c: Remove comment about AIX wanting "top" subtracted
2622 from 7; the above explains it.
2624 Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2626 * mips-tdep.c (init_extra_frame_info): Use frame relative stack
2627 pointer value when fixing up the frame at the start of a function.
2629 Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
2631 * lynx-nat.c (fetch_core_registers): Load the I & L regs for the
2632 Sparc from the stack.
2634 Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2636 * remote-mips.c (mips_initialize): Clear mips_initializing via
2637 cleanup chain, not directly.
2639 * ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
2640 of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
2641 munging the timeout due to the limited range of c_cc[VTIME].
2643 * fork-child.c, inferior.h (fork_inferior): New argument shell_file.
2644 * procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
2645 m3-nat.c (m3_create_inferior): Pass it.
2646 * procfs.c: Remove ptrace function. It was declared in a way which
2647 conflicted with the prototype in unistd.h on Solaris.
2649 Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2651 * sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
2652 in the sigcontext if it is a signal trampoline frame.
2653 * config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
2654 Define for Solaris2.
2656 Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
2658 * sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
2659 config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
2660 tm-sparc.h so they can be overridden if necessary.
2662 Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
2664 * lynx-nat.c: Add Sparc support.
2665 * sparcly-nat.c: Remove. It's useless.
2666 * config/sparc/nm-sparclynx.h: Rewrite.
2667 * config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
2669 * config/sparc/tm-sparclynx.h: Rewrite.
2671 Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2673 * rs6000-pinsn.c: Use the new disassembler in the opcodes
2674 directory. Old code was discarded, since the new opcode table has
2677 Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
2679 * Makefile.in (realclean): Remove info files per make-stds.texi.
2681 Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2683 * dbxread.c (end_psymtab): Only patch psymtab textlow and texthigh
2684 if N_SO_ADDRESS_MAYBE_MISSING is defined.
2685 * config/sparc/tm-sun4sol2.h: Define it.
2687 Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2689 * printcmd.c (print_address_symbolic): Unconditionally use msymbol
2690 if we did not find a symbol.

2697 * hppab-nat.c (call_ptrace): Delete redundant function.
2698 (kill_inferior, attach, detach, child_resume): Likewise.
2699 (child_xfer_memory): Likewise.
2701 * hppah-nat.c (call_ptrace): Delete redundant function.
2702 (kill_inferior, attach, detach, child_resume): Likewise.
2704 * config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
2706 * config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
2708 * config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
2710 * config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
2711 (CHILD_XFER_MEMORY): Define.
2712 (PT_*): Define so that generic infptrace.c code can be used.
2714 Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2716 * xcoffread.c (xcoff_symfile_read): Make second parameter a
2717 struct section_offsets *, not a (nonexistent) struct section_offset *.
2719 * xcoffread.c (read_xcoff_symtab): Make main_aux just a union
2720 internal_xcoff_symtab, not an array of one of them. Change lots of
2721 "main_aux" to "&main_aux" and so on.
2723 * coffread.c, xcoffread.c: Include <coff/internal.h>
2726 Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2728 * coffread.c (coff_getfilename): Make it not static.
2730 * xcoffread.c (read_xcoff_symtab): complain() not abort().
2732 * xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
2733 a completely gratuitous difference between xcoffread.c and coffread.c).
2735 Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2737 * infrun.c (wait_for_inferior): Don't set frame for
2738 step_resume_breakpoint for IN_SIGTRAMP cases.
2740 * infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
2741 breakpoint.c (bpstat_what): Move step_resume from its own field of
2742 the struct bpstat_what into the main_action. Make it override
2743 other breakpoints. This is a conservative change in the sense
2744 that before the step resume breakpoint was a breakpoint.c
2745 breakpoint, hitting the step resume breakpoint overrode even
2746 calling bpstat_stop_status.
2748 Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2750 * infrun.c (normal_stop): Set stop_pc after popping the dummy frame
2751 in case execution was stopped in the called function.
2752 * stack.c (print_frame_info, frame_info): If backtracing through
2753 a call dummy, handle the starting source line number on a line
2754 boundary like backtracing through sigtramp.
2755 * sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
2756 for call dummy frame right. Remove old test for dummy frame,
2757 it has been unused at least since gdb-3.5.
2758 * sparc-tdep.c (sparc_push_dummy_frame): Set return address register
2761 Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

2765 Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2767 * infrun.c (signals_info), target.c (target_signal_from_name):
2768 Use ugly casts to avoid enumvar < enumvar or enumvar++.
2770 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2772 * ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.
2773 * inflow.c (terminal_ours_1): When discussing how to deal with the
2774 tty state, make note of query() as well as readline.

2777 signals for which stop and print are cleared by default.
2779 Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)

2787 by linker stub unwind descriptors.
2788 (frameless_function_invocation): Likewise.
2789 (frame_chain_valid): Likewise.
2790 * paread.c (compare_unwind_entries): New function for sorting
2791 unwind table entries.
2792 (read_unwind_info): Rewrite to remove dependency on host endianness.
2793 Read in data from the $UNWIND_END$ subspace which contains linker
2794 stub unwind descriptors. Merge that data into the basic unwind
2797 * hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
2799 Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2801 * xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
2802 from either the symbol name or the auxent.
2803 * coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
2806 Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
2808 * Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
2810 Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2812 * README: Update notes for alpha port.
2814 Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2816 * i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
2817 for operation fault, constraint fault, and type fault.
2819 Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2821 * Makefile.in (init.c): Add comment explaining formatting conventions.
2823 * c-exp.y (parse_number): Assign to temporary between the right
2824 shifts, to work around a bug in the SCO compiler.
2826 * Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
2827 Add various files which were added to GDB recently.
2829 * xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
2832 * Makefile.in: Add mostlyclean target.
2834 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2838 Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
2840 * main.c (show_commands): Make return type of extern
2841 history_get be HIST_ENTRY, rather than struct _hist_entry.
2842 (The latter loses with the upcoming merged readline.)
2844 Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2846 * minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
2847 const char *, not char *.
2849 * symtab.h (struct symbol): Make section short, not unsigned short.
2851 * symtab.c (lookup_symbol): Add comment about QUIT here.
2853 * utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
2855 * c-exp.y (parse_number): Check for overflow regardless of range
2856 checking. Fix overflow check to use unsigned LONGEST, not
2859 * c-exp.y (parse_number): Make it so that integer constants are
2860 builtin_type_long_long if builtin_type_long isn't big enough or if
2861 an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
2863 * c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
2864 Print our "()" first, then recurse for the target type.
2866 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2868 * remote-udi.c (udi_create_inferior): Quote empty execfile argument.
2870 * gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
2872 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2874 * utils.c (request_quit): Re-establish signal handler regardless
2877 * config/mips/xm-irix4.h: Define HAVE_TERMIOS.
2879 Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2881 * i960-tdep.c: Include target.h.
2883 Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
2885 * lynx-nat.c (sys/wait.h): Don't use absolute pathname.
2887 Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
2889 * lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
2890 changes (status -> ourstatus; declare status, etc.).
2891 * config/nm-lynx.h: Fix child_wait prototype and include target.h.
2893 Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2895 * Makefile.in (ALLPARAM): Add config/nm-lynx.h.
2897 Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
2899 * remote-mips.c (mips_request, mips_wait): Correct prototypes.
2901 Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2903 * config/i386/xm-linux.h: Define HAVE_TERMIOS.
2905 Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2907 * config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
2909 Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2911 * remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
2912 is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
2914 * mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
2917 Add search to target vector (#if 0'd until after 4.12):
2918 * target.h (to_search, target_search): Add.
2919 * gdbcore.h, core.c (generic_search): Add.
2920 * remote.c (remote_search): Add.
2921 * a29k-tdep.c (init_frame_info): Use target_search to find traceback
2924 * printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
2925 is on, call find_pc_function rather than relying just on the minimal
2926 symbols (probably only matters for symbol readers which don't put
2927 statics in the minimal symbols, but changing this strikes me as
2928 not conservative enough).
2929 Initialize name_location in all cases.
2930 If no symbol and no msymbol, don't print anything symbolic.
2932 * a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
2934 Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
2936 * printcmd.c (print_address_symbolic): Make it search the
2937 symtabs for variables as well as functions. Add `set print
2938 fast-symbolic-addr' and default it to fast (the old way).
2939 Print line numbers for data items as well as functions.
2941 * symtab.c (find_addr_symbol): Return the symtab and the symbol
2942 address, if a symbol is found (take two more args pointing to
2943 where to store these results).
2945 * symtab.h (find_addr_symbol): Add prototype.
2947 Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2949 * objfiles.h: Fix comments to reflect the fact that the phrase
2950 "top of stack" always refers to where the pushing and popping takes
2951 place, regardless of whether it is at the highest or lowest address.
2953 Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
2955 * mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
2956 compiler generated tag names.
2957 * mdebugread.c (parse_type): Handle cross references to qualified
2959 * valops.c (value_struct_elt): Improve error message if the
2960 address of a method is requested from an object instance.
2961 * valops.c (search_struct_method): Make name_matched non-static
2962 to get it initialized correctly.
2963 * config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
2964 exclude segment register which are not writable on newer SCO versions.
2966 Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
2968 * go32-xdep.c: Remove unused function uerror.
2969 (sigsetmask): Declare return type. Declare argument (to match the
2970 way it is called). Explicitly return 0.
2972 Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
2974 * symtab.h (struct symbol, general_symbol_info, minimal_symbol,
2975 partial_symbol): Shrink the storage sizes of symbols, by making
2976 enums into 1-byte bitfields when compiled __GNUC__, moving all the
2977 enums and small ints to the end of each struct to improve
2978 alignment, and switching the section number from int to unsigned
2981 Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
2983 * symtab.c (find_addr_symbol): New routine that will find the nearest
2984 symbol associated with an address. It does so by exhaustive
2985 search of the symtabs, so it's slow but complete.
2987 Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
2989 * coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
2990 to [0,0] rather than [0, end of first source file]. This avoids
2991 problems with other parts of GDB looking for linetables in the
2992 _globals_ symtab. Eliminate variables num_object_files and
2993 first_object_file_end.
2995 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
2997 * a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
2998 (pop_frame): Restore PC2 and LR0 from dummy frames.
2999 (push_dummy_frame): Save PC2 and LR0 into dummy frames.
3000 (setup_arbitrary_frame): Handle 3 args and set up real frames.
3001 * config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
3002 (DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
3003 (SETUP_ARBITRARY_FRAME): Define.
3005 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3007 * infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
3009 Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
3011 * remote-udi.c (udi_resume): Correct prototype.
3013 Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
3015 * config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
3016 hppa_frame_find_saved_regs.
3017 * hppa-tdep.c (dig_fp_from_stack): Delete function.
3018 (prologue_inst_adjust_sp): New function.
3019 (is_branch, inst_saves_gr, inst_saves_fr): New functions.
3020 (skip_prologue): Completely rewrite to use unwind information.
3021 (hppa_frame_find_saved_regs): Likewise.
3023 Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3025 * remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
3026 to convert a signal number with appropriate bounds checking.
3028 * remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
3030 Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
3032 * stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
3033 print a newline to end the display anyway.
3035 * sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
3036 coprocessor status regs) when popping a frame. This fixes
3037 float exceptions that occur after calling inferior functions.
3039 * sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
3040 Read and write the fsr (float status register) to/from the child
3041 process along with the float regs. Remove Peter Schauer's change
3042 of May 24 '93, which has higher overhead and doesn't solve the
3043 real problem (which was that FSR wasn't being set).
3045 Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
3047 * a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
3048 stack overflow check isn't right after the register stack
3049 adjustment instruction. Metaware R2.3u compiler moves other
3050 things in front of it. This fix isn't perfect but is what's
3053 Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3055 * c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
3057 * config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
3058 character filenames.
3059 * configure.in: Change accordingly.
3061 Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
3063 * m68k-stub.c, sparc-stub.c: removed spurious introduction of
3064 _filtered io routines from these two files.
3066 Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
3068 * config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
3069 config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
3070 * mdebugread.c (parse_symbol): Handle enum sh.type produced by
3072 * mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
3074 Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3076 * utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
3077 printing to gdb_stderr.
3079 * remote-udi.c (udi_kill): Don't close the connection, just set
3080 inferior_pid to zero.
3081 (udi_mourn): Call remove_breakpoints.
3083 * remote-udi.c: Remove obsolete need_artificial_traps comment.
3085 * i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
3087 Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
3089 * symtab.c (lookup_symbol): Don't try adding .c to the name.
3091 * remote-bug.c: At the start of each section, reset srec_frame
3094 * target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
3095 * target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
3096 * infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
3097 code which looks for those two waitkinds. Use switch statement.
3098 * config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
3099 CHILD_SPECIAL_WAITSTATUS.
3101 * procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
3102 * Move target_signal_from_host, target_signal_to_host, and
3103 store_waitstatus from inftarg.c to target.c. procfs needs them.
3104 * target.c: Include "wait.h" and <signal.h>.
3105 * target.h, infrun.c (proceed), proceed callers: Pass new code
3106 TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
3107 enums being treated as unsigned and is cleaner.
3108 * infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
3110 * infcmd.c (signal_command), infrun.c (signals_info):
3111 Don't allow user to specify numeric equivalent of
3112 TARGET_SIGNAL_DEFAULT.
3114 Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
3116 * config/alpha/alpha-netware.mt: New target support for Alpha
3118 * configure.in: Add alpha-*-netware* target.

3122 * remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
3124 Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
3126 * target.h: Add enum target_waitkind, enum target_signal, and
3127 struct target_waitstatus. Change status argument to target_wait to
3128 be struct target_waitstatus * instead of int *.
3129 * target.h, infrun.c, all targets: Change type of signal arguments
3130 to resume(), proceed(), and target_resume() from int to enum
3132 * All targets (*_wait, *_resume): Change accordingly.
3133 * infcmd.c (program_info, signal_command), throughout infrun.c,
3134 * fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
3135 * convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
3136 signal code stuff right with the new signals would be non-trivial).
3137 * inferior.h (stop_signal): Make it enum target_signal not int.
3138 * target.c, target.h (target_signal_to_string, target_signal_to_name,
3139 target_signal_from_name): New functions.
3140 * inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
3141 store_waitstatus): New functions.
3142 * procfs.c (procfs_notice_signals): Use them.
3143 * i960-tdep.c (i960_fault_to_signal): New function, to replace
3145 * config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
3147 * objfiles.c (build_objfile_section_table): Don't abort() if
3148 objfile->sections is already set.
3150 * objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
3151 to match recent change to exec.c.
3155 * main.c (print_gdb_version): Change year to 1994.
3157 * ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
3158 * Makefile.in (NONSRC): Add ChangeLog-93.
3160 Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
