symbols do not live in the shared library transfer table.
* ch-exp.y (decode_integer_value, match_character_literal,
match_bitstring_literal): Guard tolower calls with isupper,
tolower on old BSD systems blindly subtracts a constant.

changes to make it compile (it doesn't link yet).
* buildsym.c (start_subfile, patch_subfile_names), demangle.c
(set_demangling_style, set_demangling_command): Use savestring not
strdup. We were not dealing properly with a NULL return from
strdup, and were not declaring strdup (the system header may or
may not have it).

types can be stub types.
* config/i386/ptx.mh (XDEPFILES): Add coredep.o. Delete infptrace.o.

the same size.
(REGISTER_VIRTUAL_TYPE): Use builtin_type_float for all FP regs.
* hppa-tdep.c (pa_print_fp_reg): Update to print even numbered FP
registers as both single and double values (fetching 2nd 32bit half

for each structure argument rather than assuming it's either
true or false for all structure arguments.
* config/pa/tm-hppa.h (REG_STRUCT_HAS_ADDR): Depend only
on the length structure passed, not the compiler used.
* config/sparc/tm-sparc.h (REG_STRUCT_HAS_ADDR): Accept additional
argument for the structure's type.
Tue Mar 22 15:28:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* values.c (set_internalvar): Don't set var->value until we are
sure there won't be an error().

Mon Mar 21 11:02:51 1994 Stu Grossman (grossman at cygnus.com)
* alpha-tdep.c: Gobs of changes (many imported from mips-tdep) to
improve remote debugging efficiency. Also fixed problems with
doing function calls for programs with no entry points.
* infcmd.c (run_stack_dummy): Use CALL_DUMMY_ADDRESS instead of
entry_point_address.
* inferior.h (PC_IN_CALL_DUMMY): ditto.
* mdebugread.c (parse_symbol, parse_procedure, parse_external,
parse_lines): Pass section_offsets info to these routines so that
we can relocate symbol table entries upon readin.
* (psymtab_to_symtab_1): Set symtab->primary to tell
objfile_relocate to do relocations for our symbols.
* (ecoff_relocate_efi): New routine to relocate adr field of PDRs
(which hang off of the symbol table).

instead of 4.
* sp64-tdep.c (target_ptr_bit, set_target_ptr_bit): Deleted,
can no longer set this at run time.
* config/sparc/sp64.mt (SIMFILES): Use remote-sim.o now.
(TM_CLIBS): Define to -lm, the simulator uses the sqrt() function.
* config/sparc/tm-sp64.h (FPS_REGNUM, CPS_REGNUM): Define (so
sparc-tdep.c compiles).
(TARGET_PTR_BIT): Must be a constant now, fix at 64.
Sat Mar 19 08:51:12 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* config/m68k/{cisco.mt,tm-cisco.h}: New files.
* Makefile.in (ALLPARAM, ALLCONFIG): Add them.
* configure.in: Recognize m68*-cisco*-*.
* Makefile.in (TAGS): Use variables directly, rather than using
find, to locate TM_FILE, XM_FILE, and NAT_FILE. This is faster
and means that these filenames no longer need be unique across all
the config/* directories.
* configure.in: Put the config/*/ into TM_FILE, etc.
* m68k-stub.c (computeSignal): Return SIGFPE, not SIGURG, for chk
and trapv exceptions.
* target.h (struct section_table), objfiles.h (struct obj_section):
Change name of field sec_ptr to the_bfd_section. More mnemonic
and avoids the (sort of, for the ptx compiler) name clash with
the name of the typedef.
* exec.c, xcoffexec.c, sparc-tdep.c, rs6000-nat.c, osfsolib.c,
solib.c, irix5-nat.c, objfiles.c, remote.c: Change users.

prim_record_minimal_symbol.
Callers: Pass it.
* regex.c (EXTEND_BUFFER): Adjust pointers within buffer by
computing their offset from the start of the old buffer and adding
to the new buffer, rather than by assuming we can add the
difference between the old buffer and the new buffer (it might not
fit in an int). Merge in cosmetic differences from emacs regex.c
version of this macro.
Wed Mar 16 15:28:54 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* Makefile.in (install-only): Fix use of program_transform_name.
Wed Mar 16 07:18:43 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* printcmd.c: Remove "set print fast-symbolic-addr off" command.
The bug which it worked around was fixed on 25 Feb 94 in coffread.c,
so I'm nuking the command.
* symtab.c (find_addr_symbol): Comment out, no longer used.
* main.c (main): Don't init_source_path for the -cd argument. Now
that source_path doesn't contain the current_directory from when
GDB started up, init_source_path is no longer useful (and is
harmful because it clobbers a source_path set in $HOME/.gdbinit).
* TODO: Remove item about line numbers being off. It is useless
and confusing without a reproducible test case (it mentions
proceed(), but I was able to step through proceed without trouble).
Tue Mar 15 13:39:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)

corrupt.
* xcoffread.c (read_xcoff_symtab): Use mst_solib_trampoline instead
of mst_unknown.

ieee-float.h to floatformat.h.
* valprint.c (val_print_string): Ignore error if the error
happened after a terminating '\0'.
* c-valprint.c (c_val_print): Never add 1 to return value from
val_print_string; just return what it returns.
* target.h (enum target_signal): Add TARGET_SIGNAL_FIRST, for
looping through all of the enums.
* infrun.c (signals_info): Use it.
Fri Mar 11 08:08:50 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* main.c (main): When printing warning about bad baud rate, don't
use warning(); it relies on current_target which isn't set up yet.
* breakpoint.c (_initialize_breakpoint): Update docstring for
tbreak to match what the code actually does. Don't mention tbreak
in docstrings for "enable once" or "enable breakpoints once".
Thu Mar 10 08:52:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* symfile.h (ADD_PSYMBOL_VT_TO_LIST): Don't put a semicolon after
while (0). That defeats the whole purpose of using do . . . while (0).
* mdebugread.c (parse_partial_symbols): Don't use ?: expression as
list for ADD_PSYMBOL_TO_LIST; the macro takes its address and
using a ?: expression as an lvalue is not portable.
* stabsread.c (define_symbol): If REG_STRUCT_HAS_ADDR, also
convert a LOC_ARG to a LOC_REF_ARG. Update code which combines
'p' and 'r' symbol descriptors into a single symbol to look for a
LOC_REF_ARG.
* README, config/sparc/tm-sparc.h: Update comments.
Wed Mar 9 21:43:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* mdebugread.c (parse_type): Do not complain for types with
an `indexNil' aux index, these are simply undefined types.
Remove indexNil check from caller of parse_type.
* mdebugread.c (parse_partial_symbols): Do not enter
stGlobal, scCommon symbols into the minimal symbol table, their
value is the size of the common, not its address.
Handle scInit, scFini, scPData and scXData sections.
Use minimal symbol type mst_file_* for stLabel symbols, instead of
mst_*.
Enter stProc symbols into the global_psymbols list once, not into
the static_psymbols_list.
Get rid of dummy psymtab if it is empty, to allow proper detection
of stripped executables.
* mdebugread.c (cross_ref): Allow cross references to Fortran
common blocks.
Wed Mar 9 15:23:19 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* stabsread.c (common_block_end, fix_common_block): Stash the

capping_global and capping_static. Fix comments regarding
N_SO_ADDRESS_MAYBE_MISSING to match the real name of the macro.

we don't end up with commons.
* parse.c: Define these variables.

which performs one (the check_sigtramp2 one) of the functions

use of the step_resume_breakpoint, make it still use the
step_resume_breakpoint, use the through_sigtramp_breakpoint, or
operate on both.
Deal with BPSTAT_WHAT_THROUGH_SIGTRAMP return from bpstat_what.
When setting the frame address of the step resume breakpoint, set
it to the address for frame *before* the call instruction is
executed, not after.

here. (supply_val, hms_fetch_register, hms_store_register): Cope
with H8/500 names too. (hms_fetch_register): Take out REGISTER_TYPE.
* sh-tdep.c (show_regs, initialize_sh_tdep): New command to print
all registers in a compact way.
Fri Feb 4 07:41:13 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* config/rs6000/tm-rs6000.h: Declare rs6000_struct_return_address
as CORE_ADDR to match definition in rs6000-tdep.c.
Fri Feb 4 01:14:20 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* dwarfread.c (process_dies): Skip nested TAG_compile_unit DIEs.
* dwarfread.c (add_partial_symbol): Do not enter opaque aggregate
definitions into the psymtab.
Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* m68k-stub.c: Treat mc68332 like mc68020 most places. Provide
a special exceptionSize for the 68332.
* remote-udi.c (udi_attach): If no arguments, print error.
Thu Feb 3 17:34:05 1994 Fred Fish (fnf@cygnus.com)
* Makefile.in (VERSION): Bump to 4.12.1
* NEWS, README: Update to match 4.12 release.
Thu Feb 3 12:38:58 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* command.c (empty_sfunc): New function.
(add_set_cmd): Use it instead of not_just_help_class_command.
(not_just_help_class_command): Change calling convention back to
what it was before yesterday's change.
* stabsread.c (read_sun_builtin_type): Skip the semicolon at the end
of the type if present.
Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* printcmd.c (decode_format): Don't blithely set the size for
an address to 'w'. Make it 'g' or 'h', depending on TARGET_PTR_BIT.
* defs.h: Just typedef CORE_ADDR to bfd_vma. Include bfd.h.
If BFD64, make a LONGEST a BFD_HOST_64_BIT.
* defs.h (longest_to_int): Don't depend on CC_HAS_LONG_LONG; instead
always just check against INT_MIN and INT_MAX (this also fixes things
if sizeof (long) > sizeof (int), e.g. Alpha).
* config/pa/tm-hppa.h, config/i386/sun386.h, config/rs6000/tm-rs6000.h:
Don't define LONGEST or BUILTIN_TYPE_LONGEST.
* gdbtypes.h: Remove BUILTIN_TYPE_LONGEST and
BUILTIN_TYPE_UNSIGNED_LONGEST.
* language.h, c-lang.c, ch-lang.c, m2-lang.c, language.c: Remove
longest_int and longest_unsigned_int.
* value.h (struct value): Just align to LONGEST, rather than worrying
about CC_HAS_LONG_LONG.
* valarith.c (value_binop): Figure out type ourself based on
sizeof (LONGEST) rather than relying on BUILTIN_TYPE_LONGEST. The
point is that we don't depend on CC_HAS_LONG_LONG anymore.
* valprint.c (val_print_type_code_int): Just call
extract_unsigned_integer directly, rather than going through
unpack_long.
* printcmd.c (decode_format): Remove code which would sometimes
change 'g' size to 'w' for integers. print_scalar_formatted handles
printing huge integers well enough, thank you.
* command.c (add_set_cmd, not_just_help_class_command): Change
to make this the sfunc, not cfunc, since that is how we call it.
* command.h: Comment difference between sfunc and cfunc.
* demangle.c (set_demangling_command): Add third arg since that
is how it is called.
(_initialize_demangler): Use sfunc, not cfunc, for
set_demangling_command, since that is how it is called.
Remove show_demangling_command; it has no effect.
* command.c (shell_escape): Report errors correctly (with error
message from strerror).
Wed Feb 2 14:35:41 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* xcoffread.c (read_xcoff_symtab): Change CSECT_LEN to use
x_scnlen.l rather than x_scnlen to match corresponding change in
coff/internal.h.
Wed Feb 2 11:16:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* gdbtypes.h, ch-typeprint.c, ch-valprint.c:
Change comments regarding TYPE_CODE_BOOL.
* language.c (boolean_type): Always return 1 for TYPE_CODE_BOOL,
regardless of the language.
(value_true): Just call value_logical_not regardless of language.
* coffread.c (coff_read_enum_type), stabsread.c (read_enum_type):
Remove #if 0'd code which makes some enums TYPE_CODE_BOOL.
* language.h: Improve comment for la_builtin_type_vector.
* m2-lang.c (_initialize_m2_language): Don't add any fields to
builtin_type_m2_bool.
Tue Feb 1 17:13:32 1994 Kevin Buettner (kev@cujo.geg.mot.com)
* config/m88k/{tm-delta88.h,tm-delta88v4.h}, m88k-tdep.c:
Define IN_SIGTRAMP and backtrace correctly through signal handlers.
Tue Feb 1 22:13:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* procfs.c (wait_fd): Handle EINTR error return from PIOCWSTOP ioctl
by restarting the ioctl.
Tue Feb 1 16:16:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* target.h (target_wait): Add comment about calling
return_to_top_level.
Tue Feb 1 12:21:00 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* coffread.c (read_one_sym): bfd_coff_swap_aux_in now takes
additional arguments.
* xcoffread.c (read_xcoff_symtab, read_symbol_lineno): Likewise.
Mon Jan 31 16:10:41 1994 Stu Grossman (grossman at cygnus.com)
* sparc-stub.c: Remove unnecessary #include of memory.h.
Mon Jan 31 12:12:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* mips-tdep.c: Remove code which sets saved_regs from
init_extra_frame_info and put it in new function mips_find_saved_regs.
(READ_FRAME_REG): Remove macro and replace uses with the expansion.
* mips-tdep.c, config/mips/tm-mips.h: When examining ->saved_regs,
check if it is NULL and call mips_find_saved_regs if so.
* remote-mips.c: Use unfiltered, not filtered, output most places.
* blockframe.c (get_prev_frame_info): Detect and stop an infinite
backtrace. Revise comments.
Mon Jan 31 09:40:33 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* mdebugread.c (parse_procedure): Remove _sigtramp kludges for
alpha and irix. The _sigtramp case has to be handled properly
in the tdep files if we have no ecoff debugging info.
* alpha-tdep.c (alpha_frame_saved_pc, alpha_frame_chain),
mips-tdep.c (mips_frame_saved_pc): Handle signal handler frames
without PC_REGNUM kludge.
* mdebugread.c (fixup_sigtramp), mips-tdep.c (read_next_frame_reg):
Clean up handling of mips sigtramp frames, improve comments.
Sat Jan 29 23:25:57 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
* paread.c (read_unwind_info): Fix typo.
* paread.c (pa_symtab_read): Update the "check_strange_names"
filter to match GCC's current output. Filter out section symbols
(which the HP linker sometimes puts in the wrong place).
Sat Jan 29 07:44:59 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* serial.h (SERIAL_SET_TTY_STATE): Comment return value.
* Makefile.in (TAGS): Just echo one line, rather than the whole thing.
* Makefile.in: Remove all references to sparcly-nat.c.
* Makefile.in (HFILES_NO_SRCDIR): Include dcache.h remote-utils.h
remote-sim.h directly, rather than via $(remote_utils_h). This avoids
duplicating serial.h and target.h.
* Makefile.in: Don't set M_INSTALL and M_UNINSTALL. These variables
are not used anywhere (a 5 Oct 1993 change removed the uses).
* config/m68k/monitor.mt (TDEPFILE): Add remote-es.o.
* config/m68k/es1800.mt: Add comment.
* remote-es.c: Extensive changes to update to current conventions.
* ser-unix.c (wait_for, hardwire_readchar) [HAVE_TERMIO, HAVE_TERMIOS]:
If the timeout is too big to fit in c_cc[VTIME], then do multiple reads
to achieve the desired timeout.
* serial.h (serial_t): Add field timeout_remaining.
Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* c-exp.y (yylex): Reenable nested type code.
Fri Jan 28 15:40:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* a29k-tdep.c (examine_tag): Add comment regarding argcount.
* remote-mips.c (mips_ops): Fix docstring.
* remote-bug.c (bug_ops): Remove spurious newline from docstring.
* config/m68k/tm-monitor.h: Changes to bring this into accordance
with the old tm-m68k-em.h:
(GDBINIT_FILENAME, DEFAULT_PROMPT): Remove.
(HAVE_68881): Don't undefine; HAVE_68881 is obsolete.
(REGISTER_NAMES): Don't muck with it; what tm-m68k.h has is fine.
Add FIXME regarding GET_LONGJMP_TARGET.
* remote-udi.c (udi_close, udi_detach, udi_kill): Add comments.
* infptrace.c (kill_inferior): Add comments.
* main.c (quit_command): Call target_close after we kill or
detach.
* remote-udi.c (udi_close): Don't error() if QUITTING.
Fri Jan 28 11:55:52 1994 Rob Savoye (rob@darkstar.cygnus.com)
* configure.in: Make m68k-coff and aout add monitor support in
addition to the standard serial support.
Fri Jan 28 08:45:02 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* mdebugread.c (psymtab_to_symtab_1): Don't complain on stLabel with
index indexNil.
Fri Jan 28 10:40:34 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* config/pa/tm-hppa.h: Define macro SMASH_TEXT_ADDRESS.
* elfread.c (record_minimal_symbol_and_info),
dwarfread.c (process_dies), paread.c (pa_symtab_read): Use it.
Thu Jan 27 15:12:23 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* i386-stub.c: Add ".text" right before "mem_fault:".
* main.c (baud_rate): Add FIXME comment about printing -1 value.
* remote-utils.c (usage): Fix message to be accurate and conform
more closely to normal conventions.
* remote-utils.c (gr_files_info): Have the exec_bfd test control
whether to show information about exec_bfd, and not control whether
to show information about device and speed.
* remote-utils.c (gr_open): If sr_get_device returns NULL, give
usage message, don't dump core.
* remote-bug.c (bug_write_memory): Use alloca, not GCC extension
for variable size array.
(bug_fetch_register, bug_store_register): Rename "value" to
"fpreg_buf" because some compilers don't like variables whose
names are the same as types.
(bug_store_register): Use a cast when converting char * to
unsigned char *.
* symmisc.c (maintenance_print_symbols): Don't refer to the name
of the command in error message (the text was referring to the old
name of the command).
* symmisc.c (dump_symtab): Fix args to fprintf_filtered.
* c-typeprint.c (c_type_print_base): Have SHOW == 0 mean to print
full details on structure elements without names. This partially
reverts the changes of 1 Jul 1993 and 31 Aug 1993; I think this aspect
of those changes was accidental.
* stack.c (parse_frame_specification): If SETUP_ARBITRARY_FRAME is
defined, make it an error to specify a single argument which is not
a frame number.
* Makefile.in (version.c), main.c (print_gdb_version): Use
host_alias and target_alias, not host_canonical and
target_canonical, to print configuration.
Wed Jan 26 10:57:21 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* parse.c (write_exp_msymbol): Use new type msymbol_addr_type instead
of builtin_type_long. It is necessary to get a type which is
TARGET_PTR_BIT bits in size; builtin_type_long might not be big enough.
Fix many sins which will come up in 32 bit x 64 bit GDB, and
various miscellaneous things discovered in the process:
* printcmd.c, defs.h (print_address_numeric): New function.
* c-valprint.c (c_val_print), ch-valprint.c (chill_val_print)
breakpoint.c (describe_other_breakpoints, breakpoint_1, mention),
cp-valprint.c (cplus_print_value), infcmd.c (jump_command),
printcmd.c, stack.c, symfile.c, symmisc.c, valprint.c:
Use it.
* utils.c, defs.h (gdb_print_address): New function.
* expprint (dump_expression), gdbtypes.h: Use it.
* breakpoint.c (describe_other_breakpoints),
symmisc.c (dump_symtab, print_symbol):
Use filtered not unfiltered I/O.
(remove_breakpoints): Remove BREAKPOINT_DEBUG code. Might as well
just run gdb under a debugger for this (and it had problems with
printing addresses, how to print b->shadow, etc.).
* buildsym.c (make_blockvector), core.c (memory_error),
exec.c (print_section_info), maint.c (print_section_table),
mdebugread.c (parse_procedure), solib.c, source.c, symfile.c,
symmisc.c, symtab.c, valops.c, valprint.c, xcoffexec.c:
Add comments saying code is broken. Marked with "FIXME-32x64".
* dbxread.c (process_one_symbol), partial-stab.h (default),
remote-vx.c (vx_run_files_info):
Don't cast int being passed to local_hex_string.
* symmisc.c (print_symbol): Don't cast long being passed to %lx.
* symtab.h (general_symbol_info): Add comment about SYMBOL_VALUE
only being a long.
* symmisc.c (print_symbol): Print "offset" in message for LOC_ARG
and LOC_LOCAL.
* printcmd.c (print_address): Remove #if 0 code with ADDR_BITS_REMOVE.
* source.c: Include <sys/types.h> regardless of USG.
Tue Jan 25 12:58:26 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* valops.c (value_assign): Set `type' after coercing toval.
* c-valprint.c (c_val_print), ch-valprint.c (chill_val_print):
Use extract_unsigned_integer to get the address of a reference.
Tue Jan 25 11:31:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* stabsread.c (STABS_CONTINUE, error_type), partial-stab.h:
AIX can use ? instead of \ for continuation. Deal with it.
* paread.c (read_unwind_info): Just assign to objfile->obj_private,
not OBJ_UNWIND_INFO. Assigning to a cast is a GCC-ism which
the HP compiler in ANSI mode doesn't like.
* main.c: When defaulting HAVE_SIGSETMASK based on USG, just do it
based on USG, rather than defining HAVE_SIGSETMASK to an
expression containing defined. Having a macro used in #if expand
to an expression containing "defined" is undefined according to
ANSI, and the HP compiler in ANSI mode doesn't do what we wanted
it to.
Mon Jan 24 20:51:29 1994 John Gilmore (gnu@cygnus.com)
* sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
Clean up the changes of 11 Jan, as recommended by Peter Schauer.
Fri Jan 21 19:10:44 1994 Per Bothner (bothner@kalessin.cygnus.com)
* ch-exp.y (match_string_literal): Allow a zero-length string.
* ch-lang.c (chill_printstr): Don't print zero-length string funny.
Sat Jan 22 17:08:48 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* i386aix-nat.c (i386_float_info): Reverse order of registers before
passing them to print_387_status.
(print_387_status): Don't subtract top from 7 before using it.
* i387-tdep.c: Remove comment about AIX wanting "top" subtracted
from 7; the above explains it.
Sat Jan 22 20:25:11 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* mips-tdep.c (init_extra_frame_info): Use frame relative stack
pointer value when fixing up the frame at the start of a function.
Sat Jan 22 12:29:13 1994 Stu Grossman (grossman at cygnus.com)
* lynx-nat.c (fetch_core_registers): Load the I & L regs for the
Sparc from the stack.
Sat Jan 22 08:30:42 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* remote-mips.c (mips_initialize): Clear mips_initializing via
cleanup chain, not directly.
* ser-unix.c (wait_for) [HAVE_TERMIO, HAVE_TERMIOS]: Make a timeout
of -1 mean forever, like in the HAVE_SGTTY case. Warn if we are
munging the timeout due to the limited range of c_cc[VTIME].
* fork-child.c, inferior.h (fork_inferior): New argument shell_file.
* procfs.c (procfs_create_inferior), inftarg.c (child_create_inferior),
m3-nat.c (m3_create_inferior): Pass it.
* procfs.c: Remove ptrace function. It was declared in a way which
conflicted with the prototype in unistd.h on Solaris.
Sat Jan 22 01:37:40 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* sparc-tdep.c (frame_saved_pc): Get the pc from the saved pc
in the sigcontext if it is a signal trampoline frame.
* config/sparc/tm-sun4sol2.h (IN_SIGTRAMP, SIGCONTEXT_PC_OFFSET):
Define for Solaris2.
Sat Jan 22 00:34:47 1994 Stu Grossman (grossman at cygnus.com)
* sparc-tdep.c, lynx-nat.c, config/sparc/tm-sparc.h,
config/sparc/tm-sparclynx.h: Move defs of FRAME_SAVED_I0/L0 to
tm-sparc.h so they can be overridden if necessary.
Fri Jan 21 17:49:28 1994 Stu Grossman (grossman at cygnus.com)
* lynx-nat.c: Add Sparc support.
* sparcly-nat.c: Remove. It's useless.
* config/sparc/nm-sparclynx.h: Rewrite.
* config/sparc/sparclynx.mh (NATDEPFILES): Replace sparcly-nat.o
with lynx-nat.o
* config/sparc/tm-sparclynx.h: Rewrite.
Fri Jan 21 19:08:48 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* rs6000-pinsn.c: Use the new disassembler in the opcodes
directory. Old code was discarded, since the new opcode table has
a different format.
Fri Jan 21 14:28:30 1994 Fred Fish (fnf@cygnus.com)
* Makefile.in (realclean): Remove info files per make-stds.texi.
Fri Jan 21 12:47:53 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

if N_SO_ADDRESS_MAYBE_MISSING is defined.
* config/sparc/tm-sun4sol2.h: Define it.
Thu Jan 20 15:04:24 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* printcmd.c (print_address_symbolic): Unconditionally use msymbol
if we did not find a symbol.
Fri Jan 21 08:20:18 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
* infptrace.c (child_xfer_memory): Only use if CHILD_XFER_MEMORY
is not defined.
* hppab-nat.c (call_ptrace): Delete redundant function.
(kill_inferior, attach, detach, child_resume): Likewise.
(child_xfer_memory): Likewise.
* hppah-nat.c (call_ptrace): Delete redundant function.
(kill_inferior, attach, detach, child_resume): Likewise.
* config/pa/hppabsd.mh (NATDEPFILES): Add infptrace.o.
* config/pa/hppahpux.mh (NATDEPFILES): Add infptrace.o.
* config/pa/nm-hppab.h (FETCH_INFERIOR_REGISTERS): Define.
* config/pa/nm-hppah.h (FETCH_INFERIOR_REGISTERS): define.
(CHILD_XFER_MEMORY): Define.
(PT_*): Define so that generic infptrace.c code can be used.
Fri Jan 21 09:23:33 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* xcoffread.c (xcoff_symfile_read): Make second parameter a
struct section_offsets *, not a (nonexistent) struct section_offset *.
* xcoffread.c (read_xcoff_symtab): Make main_aux just a union
internal_xcoff_symtab, not an array of one of them. Change lots of
"main_aux" to "&main_aux" and so on.
* coffread.c, xcoffread.c: Include <coff/internal.h>
before "symfile.h".
Thu Jan 20 17:30:55 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* coffread.c (coff_getfilename): Make it not static.
* xcoffread.c (read_xcoff_symtab): complain() not abort().
* xcoffread.c (struct coff_symbol): Rename c_nsyms to c_naux (removes
a completely gratuitous difference between xcoffread.c and coffread.c).
Wed Jan 19 15:09:44 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* infrun.c (wait_for_inferior): Don't set frame for
step_resume_breakpoint for IN_SIGTRAMP cases.
* infrun.c (wait_for_inferior), breakpoint.h (struct bpstat_what),
breakpoint.c (bpstat_what): Move step_resume from its own field of
the struct bpstat_what into the main_action. Make it override
other breakpoints. This is a conservative change in the sense
that before the step resume breakpoint was a breakpoint.c
breakpoint, hitting the step resume breakpoint overrode even
calling bpstat_stop_status.
Wed Jan 19 12:40:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (normal_stop): Set stop_pc after popping the dummy frame
in case execution was stopped in the called function.

a call dummy, handle the starting source line number on a line
boundary like backtracing through sigtramp.
* sparc-tdep.c (sparc_frame_find_saved_regs): Get frame address
for call dummy frame right. Remove old test for dummy frame,
it has been unused at least since gdb-3.5.
* sparc-tdep.c (sparc_push_dummy_frame): Set return address register
of the dummy frame.
Tue Jan 18 16:16:35 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

Tue Jan 18 14:09:25 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (signals_info), target.c (target_signal_from_name):
Use ugly casts to avoid enumvar < enumvar or enumvar++.
Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* ser-unix.c (hardwire_noflush_set_tty_state): Don't muck with ICANON.

tty state, make note of query() as well as readline.
* infrun.c (_initialize_infrun): Add TARGET_SIGNAL_POLL to list of
signals for which stop and print are cleared by default.
Mon Jan 17 20:00:51 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
* config/pa/tm-hppa.h (unwind_table_entry): Use one of the
reserved fields to hold a stub unwind entry type. Fix typo.
(stub_unwind_entry): New structure for raw stub unwind entries.
(stub_unwind_types): The types of stubs we may encounter.

(frame_chain_valid): Likewise.
* paread.c (compare_unwind_entries): New function for sorting
unwind table entries.
(read_unwind_info): Rewrite to remove dependency on host endianness.
Read in data from the $UNWIND_END$ subspace which contains linker
stub unwind descriptors. Merge that data into the basic unwind
table.
* hppab-nat.c (_initialize_kernel_u_addr): Delete unwanted functions.
Mon Jan 17 22:00:15 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* xcoffread.c (read_xcoff_symtab, case C_FILE): Accept the name
from either the symbol name or the auxent.
* coffread.c, symfile.h (coff_getfilename): Renamed from getfilename,
no longer static.
Mon Jan 17 13:35:01 1994 Fred Fish (fnf@cygnus.com)
* Makefile.in (ALLPARAM): Change irix5.h to nm-irix5.h.
Mon Jan 17 12:35:42 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* README: Update notes for alpha port.
Mon Jan 17 11:15:57 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* i960-tdep.c (i960_fault_to_signal): Return TARGET_SIGNAL_ILL
for operation fault, constraint fault, and type fault.
Sun Jan 16 12:46:01 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* Makefile.in (init.c): Add comment explaining formatting conventions.
* c-exp.y (parse_number): Assign to temporary between the right
shifts, to work around a bug in the SCO compiler.
* Makefile.in (ALLCONFIG, ALLPARAM, ALLDEPFILES, HFILES_NO_SRCDIR):
Add various files which were added to GDB recently.
* xcoffread.c (process_xcoff_symbol): Only change 'V' to 'S' if not
within_function.
* Makefile.in: Add mostlyclean target.
Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* Version 4.11.4.
Sat Jan 15 18:27:34 1994 Per Bothner (bothner@kalessin.cygnus.com)
* main.c (show_commands): Make return type of extern
history_get be HIST_ENTRY, rather than struct _hist_entry.
(The latter loses with the upcoming merged readline.)
Sat Jan 15 10:20:13 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* minsyms.c (prim_record_minimal_symbol_and_info): Make tempstring
const char *, not char *.
* symtab.h (struct symbol): Make section short, not unsigned short.
* symtab.c (lookup_symbol): Add comment about QUIT here.
* utils.c (fputs_unfiltered): Call fputs, not fputs_maybe_filtered.
* c-exp.y (parse_number): Check for overflow regardless of range
checking. Fix overflow check to use unsigned LONGEST, not
unsigned int.
* c-exp.y (parse_number): Make it so that integer constants are
builtin_type_long_long if builtin_type_long isn't big enough or if
an "LL" suffix is used. Properly handle "UL" or "LU" suffixes.
* c-typeprint.c (c_type_print_varspec_suffix, case TYPE_CODE_FUNC):
Print our "()" first, then recurse for the target type.
Fri Jan 14 21:55:39 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* remote-udi.c (udi_create_inferior): Quote empty execfile argument.
* gdbserver/low-lynx.c: Include <sys/wait.h> not "/usr/include/wait.h".
Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)

Fri Jan 14 17:12:28 1994 Stan Shebs (shebs@andros.cygnus.com)
* lynx-nat.c (sys/wait.h): Don't use absolute pathname.
Fri Jan 14 11:06:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* lynx-nat.c (child_wait): Fix thinkos in struct target_waitstatus
changes (status -> ourstatus; declare status, etc.).
* config/nm-lynx.h: Fix child_wait prototype and include target.h.
Fri Jan 14 14:17:06 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* Makefile.in (ALLPARAM): Add config/nm-lynx.h.
Fri Jan 14 11:49:44 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* remote-mips.c (mips_request, mips_wait): Correct prototypes.
Fri Jan 14 11:37:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* config/i386/xm-linux.h: Define HAVE_TERMIOS.
Fri Jan 14 01:04:36 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* config/alpha/tm-alpha.h (CALL_DUMMY): Improve comment.
Thu Jan 13 10:32:38 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* remote-vx.c (vx_wait): Only call i960_fault_to_signal if I80960
is defined. Otherwise just report TARGET_SIGNAL_UNKNOWN.
* mips-tdep.c (mips_push_arguments): Byteswap struct_addr before
writing it.
Add search to target vector (#if 0'd until after 4.12):
* target.h (to_search, target_search): Add.
* gdbcore.h, core.c (generic_search): Add.
* remote.c (remote_search): Add.
* a29k-tdep.c (init_frame_info): Use target_search to find traceback
tag.
* printcmd.c (print_address_symbolic): If set print fast-symbolic-addr
is on, call find_pc_function rather than relying just on the minimal
symbols (probably only matters for symbol readers which don't put
statics in the minimal symbols, but changing this strikes me as
not conservative enough).
Initialize name_location in all cases.
If no symbol and no msymbol, don't print anything symbolic.
* a29k-tdep.c (push_dummy_frame): Add comment about saving lr0.
Wed Jan 12 20:53:16 1994 John Gilmore (gnu@cygnus.com)
* printcmd.c (print_address_symbolic): Make it search the
symtabs for variables as well as functions. Add `set print
fast-symbolic-addr' and default it to fast (the old way).
Print line numbers for data items as well as functions.
* symtab.c (find_addr_symbol): Return the symtab and the symbol
address, if a symbol is found (take two more args pointing to
where to store these results).
* symtab.h (find_addr_symbol): Add prototype.
Wed Jan 12 19:32:11 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* objfiles.h: Fix comments to reflect the fact that the phrase
"top of stack" always refers to where the pushing and popping takes
place, regardless of whether it is at the highest or lowest address.
Wed Jan 12 13:23:37 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* mdebugread.c (parse_symbol): Do not set TYPE_TAG_NAME for
compiler generated tag names.
* mdebugread.c (parse_type): Handle cross references to qualified
aggregate types.
* valops.c (value_struct_elt): Improve error message if the
address of a method is requested from an object instance.
* valops.c (search_struct_method): Make name_matched non-static
to get it initialized correctly.
* config/i386/nm-i386sco.h (CANNOT_STORE_REGISTER): Define to
exclude segment register which are not writable on newer SCO versions.
Wed Jan 12 14:44:45 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* go32-xdep.c: Remove unused function uerror.
(sigsetmask): Declare return type. Declare argument (to match the
way it is called). Explicitly return 0.
Wed Jan 12 01:44:25 1994 John Gilmore (gnu@cygnus.com)
* symtab.h (struct symbol, general_symbol_info, minimal_symbol,
partial_symbol): Shrink the storage sizes of symbols, by making
enums into 1-byte bitfields when compiled __GNUC__, moving all the
enums and small ints to the end of each struct to improve
alignment, and switching the section number from int to unsigned
short.
Wed Jan 12 00:16:26 1994 John Gilmore (gnu@cygnus.com)
* symtab.c (find_addr_symbol): New routine that will find the nearest
symbol associated with an address. It does so by exhaustive
search of the symtabs, so it's slow but complete.
Tue Jan 11 23:57:30 1994 John Gilmore (gnu@cygnus.com)
* coffread.c (read_coff_symtab): Set PC bounds of _globals_ symtab
to [0,0] rather than [0, end of first source file]. This avoids
problems with other parts of GDB looking for linetables in the
_globals_ symtab. Eliminate variables num_object_files and
first_object_file_end.
Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
* a29k-tdep.c (init_frame_info): Cast null arg to examine_tag.
(pop_frame): Restore PC2 and LR0 from dummy frames.
(push_dummy_frame): Save PC2 and LR0 into dummy frames.
(setup_arbitrary_frame): Handle 3 args and set up real frames.
* config/a29k/tm-a29k.h (FRAME_NUM_ARGS): Update comments.
(DUMMY_FRAME_RSIZE): Add 2 longwords for PC2 and LR0.
(SETUP_ARBITRARY_FRAME): Define.
Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* infrun.c, config/mips/tm-irix5.h: Remove #if 0'd AT_FUNCTION_START.
Tue Jan 11 14:27:03 1994 Ian Lance Taylor (ian@tweedledumb.cygnus.com)
* remote-udi.c (udi_resume): Correct prototype.
Tue Jan 11 11:10:30 1994 Jeffrey A. Law (law@snake.cs.utah.edu)
* config/pa/tm-hppa.h (FRAME_FIND_SAVED_REGS): Call
hppa_frame_find_saved_regs.
* hppa-tdep.c (dig_fp_from_stack): Delete function.
(prologue_inst_adjust_sp): New function.
(is_branch, inst_saves_gr, inst_saves_fr): New functions.
(skip_prologue): Completely rewrite to use unwind information.
(hppa_frame_find_saved_regs): Likewise.
Tue Jan 11 06:59:10 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* remote-mips.c (mips_wait): Use new function mips_signal_from_protocol
to convert a signal number with appropriate bounds checking.
* remote-mips.c (mips_wait): Fix typos (0x177 -> 0177, 0x377 -> 0377).
Tue Jan 11 00:53:46 1994 John Gilmore (gnu@cygnus.com)
* stack.c (frame_info): If FRAME_FIND_SAVED_REGS isn't defined,
print a newline to end the display anyway.
* sparc-tdep.c (sparc_pop_frame): Pop the fsr and csr (float and
coprocessor status regs) when popping a frame. This fixes
float exceptions that occur after calling inferior functions.
* sparc-nat.c (fetch_inferior_registers, store_inferior_registers):
Read and write the fsr (float status register) to/from the child
process along with the float regs. Remove Peter Schauer's change
of May 24 '93, which has higher overhead and doesn't solve the
real problem (which was that FSR wasn't being set).
Mon Jan 10 23:16:42 1994 John Gilmore (gnu@cygnus.com)
* a29k-tdep.c (examine_prologue): Don't worry if the ASGEQ
stack overflow check isn't right after the register stack
adjustment instruction. Metaware R2.3u compiler moves other
things in front of it. This fix isn't perfect but is what's
running.
Mon Jan 10 20:08:23 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* c-valprint.c (c_val_print): Treat TYPE_CODE_RANGE like TYPE_CODE_INT.
* config/alpha/alpha-netware.mt: Rename to alpha-nw.mt for 14
character filenames.
* configure.in: Change accordingly.
Mon Jan 10 15:48:36 1994 Tom Lord (lord@rtl.cygnus.com)
* m68k-stub.c, sparc-stub.c: removed spurious introduction of
_filtered io routines from these two files.
Fri Jan 7 12:42:45 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* config/i386/tm-i386v.h, config/m68k/tm-m68k.h, config/mips/tm-mips.h,
config/vax/tm-vax.h (CALL_DUMMY_BREAKPOINT_OFFSET): Define.
* mdebugread.c (parse_symbol): Handle enum sh.type produced by
DEC c89.
* mdebugread.c (add_line): Handle zero linenos produced by DEC c89.
Fri Jan 7 12:55:25 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* utils.c (print_sys_errmsg): Call gdb_flush (gdb_stdout) before
printing to gdb_stderr.
* remote-udi.c (udi_kill): Don't close the connection, just set
inferior_pid to zero.
(udi_mourn): Call remove_breakpoints.
* remote-udi.c: Remove obsolete need_artificial_traps comment.
* i386b-nat.c (sregmap): If sEAX, etc., not defined, use tEAX, etc.
Thu Jan 6 07:17:53 1994 Jim Kingdon (kingdon@deneb.cygnus.com)
* symtab.c (lookup_symbol): Don't try adding .c to the name.
* remote-bug.c: At the start of each section, reset srec_frame
back to 160.
* target.h: Add TARGET_WAITKIND_LOADED and TARGET_WAITKIND_SPURIOUS.
* target.c (store_waitstatus): Add CHILD_SPECIAL_WAITSTATUS hook.
* infrun.c (wait_for_inferior): Replace SIGTRAP_STOP_AFTER_LOAD with
code which looks for those two waitkinds. Use switch statement.
* config/rs6000/tm-rs6000.h: Replace SIGTRAP_STOP_AFTER_LOAD with
CHILD_SPECIAL_WAITSTATUS.
* procfs.c (procfs_wait): Fix argument name to match 4 Jan changes.
* Move target_signal_from_host, target_signal_to_host, and
store_waitstatus from inftarg.c to target.c. procfs needs them.
* target.c: Include "wait.h" and <signal.h>.
* target.h, infrun.c (proceed), proceed callers: Pass new code
TARGET_SIGNAL_DEFAULT instead of -1. This avoids problems with
enums being treated as unsigned and is cleaner.
* infrun.c (signals_info): Don't print TARGET_SIGNAL_DEFAULT or
TARGET_SIGNAL_0.
* infcmd.c (signal_command), infrun.c (signals_info):
Don't allow user to specify numeric equivalent of
TARGET_SIGNAL_DEFAULT.
Tue Jan 4 15:34:36 1994 Stu Grossman (grossman@cygnus.com)
* config/alpha/alpha-netware.mt: New target support for Alpha
running Netware.
* configure.in: Add alpha-*-netware* target.
Tue Jan 4 14:51:35 1994 Stan Shebs (shebs@andros.cygnus.com)
* remote-mips.c (mips_wait): Fix ref to TARGET_WAITKIND_STOPPED.
Tue Jan 4 09:47:14 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* target.h: Add enum target_waitkind, enum target_signal, and
struct target_waitstatus. Change status argument to target_wait to
be struct target_waitstatus * instead of int *.
* target.h, infrun.c, all targets: Change type of signal arguments
to resume(), proceed(), and target_resume() from int to enum
target_signal.
* All targets (*_wait, *_resume): Change accordingly.
* infcmd.c (program_info, signal_command), throughout infrun.c,
* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
signal code stuff right with the new signals would be non-trivial).
* inferior.h (stop_signal): Make it enum target_signal not int.
* target.c, target.h (target_signal_to_string, target_signal_to_name,
target_signal_from_name): New functions.
* inftarg.c, target.h (target_signal_to_host, target_signal_from_host,
store_waitstatus): New functions.
* procfs.c (procfs_notice_signals): Use them.
* i960-tdep.c (i960_fault_to_signal): New function, to replace
print_fault.
* config/i960/tm-i960.h: Don't define PRINT_RANDOM_SIGNAL.
* objfiles.c (build_objfile_section_table): Don't abort() if
objfile->sections is already set.
* objfiles.c (add_to_objfile_sections): Check SEC_ALLOC not SEC_LOAD
to match recent change to exec.c.
* Version 4.11.3.
* main.c (print_gdb_version): Change year to 1994.
* ChangeLog, ChangeLog-93: Split ChangeLog at 1994.
* Makefile.in (NONSRC): Add ChangeLog-93.
Mon Jan 3 11:57:29 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* stabsread.c (read_type): Allow defining several type numbers
at once (e.g. "(1,2)=(3,4)="...).
* stabsread.c (read_enum_type): Use TARGET_INT_BIT not sizeof (int).
* breakpoint.c (frame_in_dummy): Check PC as well as frame.
Mon Jan 3 02:47:03 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* mdebugread.c (psymtab_to_symtab_1): Only pass N_STAB symbols
to process_one_symbol.
* symtab.c (find_pc_psymbol): Search global_psymbols as well to
avoid caching a bad endaddr in find_pc_partial_function.
Sun Jan 2 21:41:17 1994 Jim Kingdon (kingdon@lioth.cygnus.com)
* config/m68k/tm-sun3.h: Don't define BELIEVE_PCC_PROMOTION.
Sat Jan 1 04:35:23 1994 Peter Schauer (pes@regent.e-technik.tu-muenchen.de)
* infrun.c (wait_for_inferior): Do not step or step resume past
the end of a one-line function we just stepped into.
