* gdb.base/long_long.exp: Correct test suite failure when printing
a long long value as a double on ARM platforms.
ARM doubles use a hybrid endian format. It is not strictly little or big
endian. It is little endian with the words swapped.
* minsyms.c: #include <ctype.h>, for msymbol_hash_iw.
(compact_minimal_symbols): Added `objfile' argument.
Put symbols in the objfile's hash table.
(install_minimal_symbols): Put symbols in the objfile's demangled
hash table.
(lookup_minimal_symbol): Use hash table to find symbol in
objfile.
(msymbol_hash_iw, msymbol_hash, add_minsym_to_hash_table): New
functions.
(prim_record_minimal_symbol_and_info): Initialize the
hash link fields of the new minimal symbol.

`demangled_hash_next'.
(msymbol_hash_iw, msymbol_hash, add_minsym_to_hash_table): Declare.
* objfiles.h (MINIMAL_SYMBOL_HASH_SIZE): New define.
(struct objfile): New fields `msymbol_hash',
`msymbol_demangled_hash'.
* mi-cmds.h: Export mi_cmd_data_write_register_values.
* mi-cmds.c (mi_cmds): Implement data-write-register-values with
mi_cmd_data_write_register_values.
* mi-main.c (mi_cmd_data_write_register_values): New
function. Write a value into a register.
* mi-disassemble.exp: Don't assume numbers for the offset
values. They can be different depending on the architecture.
* mi-watch.exp (test_watchpoint_triggering): In same cases the
type can be 'hw wathcpoint' not just 'watchpoint'. Adjust for that.
* basics.c (callee4): Make the function return something,
otherwise the return value is undefined.
Allow GDB to run on Linux 2.0 again.
* config.in: Add HAVE_PTRACE_GETREGS.
* configure.in: Check if <sys/ptrace.h> defines PTRACE_GETREGS.
* configure: Regenerated.
* config/i386/nm-linux.h (CANNOT_FETCH_REGISTER,
CANNOT_STORE_REGISTER): New defines.
* i386-linux-nat.c (have_ptrace_getregs): New variable.
(PTRACE_XFER_TYPE, CANNOT_FETCH_REGISTER, fetch_register,
old_fetch_inferior_registers, CANNOT_STORE_REGISTER,
store_register, old_store_inferior_registers): Copied over from
`inptrace.c' as a temporary measure.
(fetch_regs, store_regs, fetch_fpregs, store_fpregs):
Conditionalize on HAVE_PTRACE_GETREGS. Define stubs if
HAVE_PTRACE_GETREGS isn't defined.
(fetch_regs): Reset `have_ptrace_getregs' if ptrace call fails
with EIO.
(fetch_inferior_registers, store_inferior_registers): Fall back on
the method use in `infptrace.c' (by calling
old_fetch_inferior_registers and old_store_inferior_registers) if
`have_ptrace_getregs' isn't set.
* i386-linux-nat.c: Use elf_gregset_t and elf_fpregset_t instead
of gregset_t and fpregset_t. Those are the only names that are
guaranteed to specify the right types for all supported Linux
systems out there.
Various doc fixes and gratitious local variable renames, all in an
attempt to stress similarities between the code and unify the
terminology used. Use ISO-C all over.
(regmap): Remove trailing comma.
(FPREG_ADDR): Renamed from FPREGSET_T_FPREG_ADDR.
(convert_to_gregset): Make static. Remove GDB_REGS argument. It
is unnecessary and wasn't used anyway. All callers changed.

(fetch_regs, store_regs): Remove unused variable `regno'.
(fill_fpregs): If REGNO is not -1, only update the specified
register.
(fetch_core_registers): Renamed from
i386_linux_fetch_core_registers. There is no need for a unique
name since the function is static anyway.
(linux_elf_core_fns): Renamed from i386_linux_nat_core_functions
since it is more descriptive.
Fix support for Linux/i386 signal trampolines. The old approach
didn't work for Linux 2.2 and beyond, and didn't work with recent
versions of the GNU C library.
* i386-tdep.c (LINUX_RT_SIGTRAMP_INSN0, LINUX_RT_SIGTRAMP_OFFSET0,
LINUX_RT_SIGTRAMP_INSN1, LINUX_RT_SIGTRAMP_OFFSET1): New defines.

(i386_linux_in_sigtramp): New function.
(i386_linux_sigcontext_addr): New function. Recognize the names
of the signal tranmpolines used by recent versions of the GNU C
library, and add support for RT signals.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET): New
defines. Moved here from config/i386/tm-linux.h.
(i386_linux_sigtramp_saved_pc, i386_linux_sigtramp_saved_sp):
Reimplement in terms of i386_linux_sigcontext_addr.

* event-loop.h: Eliminate uses of PTR, use 'void *' instead.
* event-top.c: Ditto.
* config/arm/linux.mh (NATDEPFILES): Removed core-regset.o.
Not used. Required to get GDB to build on glibc 2.1.3.
* config/arm/tm-linux.h (LOWEST_PC): Undefine LOWEST_PC
before redefining. Gets rid of compiler warning.
* arm-linux-nat.c (fetch_nw_fpe_*):
Renamed to fetch_nwfpe_* to use the same naming convention
as in the Linux kernel. Modified prototype to get rid of
unused parameters.
(store_nw_fpe_*): Renamed to store_nwfpe_* to use the same
naming convention as in the Linux kernel. Fixed calls to
fetch_nwfpe_*.
(store_fpregs): Fixed calls to store_nwfpe_*. Removed
unused variable.
* gnu-nat.c: Include "gdbthread.h". Include <hurd.h>.
Reorder headers a bit. Overall cleanup and minor reformatting.
(MIG_SERVER_DIED): Remove define.
(proc_update_sc): Add braces to silence compiler warning.

From: Thomas Zenker <thz@Lennartz-electronic.DE>
* rdi-share/hsys.c: to compile under 4.4BSD derived systems (FreeBSD,
NetBSD...) sys_errlist should not be declared in hsys.c.
NEED_SYSERRLIST is set already by configure, so we can use it.
* rdi-share/unixcomm.c: 4.4BSD derived systems define BSD, but are
posix compliant and we should not work with the old compatibility
stuff. Because of that I undef BSD in case of FBSD etc and include
sys/ioctl to get the flags.
* rdi-share/unixcomm.c: If the TIOCEXCL flags exists set serial line
for exclusive use.
* config/arm/tm-wince.h: New file.
* config/arm/wince.mt New file.

* config/mips/wince.mt New file.
* wince.c: New file.
* wince-stub.c: New file.
* wince-stub.h: New file.
* sh-tdep.c: Use correct register names for Windows CE.
(error_return, quit_return): Merge into catch_return pointer.
(return_to_top_level): Update comment. Longjmp to *catch_errors,
and communicate reason to catch_errors via setjmp return value.
(catch_errors): Always catch both quit and error, and if a catch
wasn't requested by caller, throw it to the next catch_error.
Replace dual longjmp buffer memcpy with single pointer change.
Add FIXME for possibly adding new interface to tell caller what
event was caught. Add extensive comments.
* defs.h (enum return_reason): Reserve 0 for use as initial
setjmp() return value.
(RETURN_MASK): New public macro to generate RETURN_MASK_* from
enum return_reason.
(RETURN_MASK_QUIT, RETURN_MASK_ERROR): Define using RETURN_MASK.
* infcmd.c (run_stack_dummy): Do not pop frame on random signal.
* valops.c (_initialize_valops): Add command "set unwindonsignal".
(hand_function_call): Test for unwind_on_signal and act accordingly.
documented.
Bring COERCE_FLOAT_TO_DOUBLE under gdbarch's control.
* valops.c (COERCE_FLOAT_TO_DOUBLE): Rework definition to be
more function-like.
(default_coerce_float_to_double, standard_coerce_float_to_double):
New functions.
(value_arg_coerce): Adjust for new definition.
* value.h (default_coerce_float_to_double,
standard_coerce_float_to_double): New declarations for the above.
* gdbarch.sh (coerce_float_to_double): New entry, replacing macro.
* gdbarch.c, gdbarch.h: Regenerated.
* tm-alpha.h, tm-fr30.h, tm-m32r.h, tm-mips.h, tm-hppa.h,
tm-rs6000.h, tm-sh.h, tm-sparc.h (COERCE_FLOAT_TO_DOUBLE): Change
definitions.
* mips-tdep.c (mips_coerce_float_to_double): Supply our own custom
function here.
(mips_gdbarch_init): Install that as our coerce_float_to_double
function.
* valops.c (COERCE_FLOAT_TO_DOUBLE): Rework definition to be
more function-like.
(default_coerce_float_to_double, standard_coerce_float_to_double):
New functions.
(value_arg_coerce): Adjust for new definition.
* value.h (default_coerce_float_to_double,
standard_coerce_float_to_double): New declarations for the above.
* gdbarch.sh (coerce_float_to_double): New entry, replacing macro.
* gdbarch.c, gdbarch.h: Regenerated.
* tm-alpha.h, tm-fr30.h, tm-m32r.h, tm-mips.h, tm-hppa.h,
tm-rs6000.h, tm-sh.h, tm-sparc.h (COERCE_FLOAT_TO_DOUBLE): Change
definitions.
* mips-tdep.c (mips_coerce_float_to_double): Supply our own custom
function here.
(mips_gdbarch_init): Install that as our coerce_float_to_double
function.
From Philippe De Muyter <phdm@macqel.be>
* event-loop.c (handle_file_event): In case of poll, enable
printing of informational message if an error/exception is
detected on the file descriptor.
* remote.c (remote_async_detach): Use target_mourn_inferior(), to
make sure that all is cleaned up after we disconnect from the
target.
(remote_detach): Ditto.
* target.c (do_target_signal_to_host): Do not use REALTIME_LO in
the conversion of the signal number. TARGET_SIGNAL_REALTIME_33 is
33 by definition, whereas REALTIME_LO might be 32 on systems that
have SIG32 such as Linux. Make sure that the signal number
returned is within the range specified by REALTIME_LO and
REALTIME_HI.
* arm-tdep.c (set_disassembly_flavor, arm_othernames,
_initialize_arm_tdep): Allows the user to choose between any of
the flavors available for the disassembly to be used in the "info
reg" command and elsewhere in gdb. It prevents having to maintain
this information in two places by using the data kept in the
opcodes directory.
* configure.in: Check for lwpid_t, psaddr_t, prgregset_t and
prfpregset_t in <sys/procfs.h>.
* config.in: Add HAVE_LWPID_T, HAVE_PSADDR_T, HAVE_PRGREGSET_T,
HAVE_PRFPREGSET_T.
* gdb_proc_service.h: Only provide typedefs for lwpid_t, psaddr_t,
prgregset_t and prfpregset_t if they are not already present.
* elfread.c (elf_symtab_read): Use offset for the section in which a
symbol resides, instead of .text section for calculating address of a
symbol.
Checked in by Jim Kingdon <kingdon@redhat.com>
* gnu-nat.c (proc_string): Make global.
(do_mach_notify_dead_name): Suppress dead name notifications if we
know that the task is dead.
1999-12-13 Mark Kettenis <kettenis@gnu.org>
* gnu-nat.c (inf_validate_task_sc): Get task info via proc server
instead of directly from the kernel. Add some hackery to make
sure that the info isn't influenced by suspension of the task in
the proc server itself.
