and P_LINK_W.
(P_PEA_FP, P_MOVL_SP_FP): New macros.
(P_MOVL, P_LEAL, P_MOVML): Macros renamed from P_MOV_L, P_LEA_L and
P_MOVM_L.
(altos_skip_prologue, isi_skip_prologue): Use P_* macros, not octal
constants.
(delta68_in_sigtramp): New function.
(delta68_frame_args_address, delta68_frame_saved_pc): Ditto.
(m68k_skip_prologue): Use P_* macros, not hex constants.
(m68k_find_saved_regs): Do not expect a fixed sequence of register save
instructions, but accept them in any order; use P_* macros, not octal
or hex constants; recognize also `fmovemx to (fp + displacement)' and
`moveml to (fp + displacement)'.
* m68/tm-delta68.h (IN_SIGTRAMP): New macro.
(FRAME_SAVED_PC, FRAME_ARGS_ADDRESS): Ditto.
* config/i386/tm-i386aix.h (I386_AIX_TARGET): Remove.

Remove
* i386-tdep.c (LOW_RETURN_REGNUM, HIGH_RETURN_REGNUM): New defines.
(i386_extract_return_value): Rewritten. Correctly support all
floating-point types and large integer types on targets that use
the standard i386 GDB register layout and return floating-point
values in the FPU.

i386_linux_sigtramp_saved_sp): Deleted. Folks rightly pointed
out that these are target-dependent, and useful in non-native
configurations. Moved to...
* i386-linux-tdep.c: ... Here, a new file.
* Makefile.in (ALLDEPFILES): Add i386-linux-tdep.c.
(i386-linux-tdep.o): New rule.
(i386-linux-nat.o): We no longer depend on frame.h.
* config/i386/linux.mt (TDEPFILES): Add i386-linux-tdep.o.
* event-loop.c (top-level) [NO_FD_SET]: Deprecate this branch.
Print an error at compile time if we are to use select, but FD_SET
is not available.
(SELECT_MASK, NBBY, FD_SETSIZE, NFDBITS, MASK_SIZE): Define only
if HAVE_POLL is not defined and NO_FD_SET *is* defined.
(create_file_handler) [!HAVE_POLL]: Use FD_SET and FD_CLR.
(delete_file_handler) [!HAVE_POLL]: Use FD_CLR and FD_ISSET.
(gdb_wait_for_event) [!HAVE_POLL]: Copy fd_set sets directly
instead of using memcpy and memset. Use FD_ISSET.

Linux-specific signal trampoline detection, and should be moved to...

* config/i386/tm-linux.h (I386_LINUX_SIGTRAMP): No need to define
this any more, since we're not enabling OS-specific code in a
OS-independent file.
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.

(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.
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.
(linux_rt_sigtramp_code): New variable.
(LINUX_RT_SIGTRAMP_LEN): New define.
(i386_linux_rt_sigtramp_start): New function. Detect start of
signal trampolines for RT signals.
(i386_linux_sigtramp): Removed.
(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.
* config/i386/tm-linux.h (LINUX_SIGCONTEXT_SIZE): Removed.
(LINUX_SIGCONTEXT_PC_OFFSET, LINUX_SIGCONTEXT_SP_OFFSET):
Moved to i386-tdep.c.
(IN_SIGTRAMP): Redefine to call i386_linux_in_sigtramp.
* 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.
Make cross-compilation for the Hurd more friendly.
