already defined.

Fix single-stepping out of signal trampolines.
	* config/i386/nm-linux.h (CHILD_RESUME): Define.
	* i386-linux-nat.c (child_resume): New function.

Jim Blandy e7ee86a99a * i386-linux-nat.c: No need to #include "frame.h" any more.

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.

Jim Blandy 17f9defb0b * i386-linux-nat.c (i386_linux_saved_pc_after_call): Lost in the
merge; reinstated.

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.

* i386-linux-nat.c (supply_fpregset): Mask off the reserved bits
	in *FPREGSETP.
	(convert_to_fpregset): Don't touch the reserved bits in *FPREGSETP.

Mark Kettenis f60300e72c 2000-03-05 Mark Kettenis <kettenis@gnu.org>
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.

Mark Kettenis 04cd15b61d 2000-01-29 Mark Kettenis <kettenis@gnu.org>
* 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.
	(convert_to_fpregset, convert_to_xfpregset): Likewise.
	(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.
