i386_linux_sigtramp_saved_pc, LINUX_SIGCONTEXT_SP_OFFSET,
i386_linux_sigtramp_saved_sp): Deleted. These all implement
Linux-specific signal trampoline detection, and should be moved to...
* i386-linux-nat.c: ... here.
* 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.
* 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.
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.
