Kevin Buettner 76fb44f49a * i386-linux-nat.c (fill_gregset): Fix botched regcache_collect()
conversion for I386_LINUX_ORIG_EAX_REGNUM.
2001-11-18 21:38:59 +00:00
Kevin Buettner 8a40674599 * i386-linux-nat.c (fill_gregset): Use regcache_collect() instead
of accessing registers[] directly.
2001-11-18 01:19:47 +00:00
Kevin Buettner 7dd945fa27 * i386-linux-nat.c (fill_gregset): Don't invoke read_register_gen()
when fetching ORIG_EAX.
2001-11-17 23:53:16 +00:00
Mark Kettenis 3fb1c83804 * i386-linux-nat.c (GETREGS_SUPPLIES, supply_gregset,
fill_gregset): Add support for "orig_eax" register.
2001-11-04 14:30:42 +00:00

Kevin Buettner 39f770628a Phase 1 of the ptid_t changes. 2001-05-04 04:15:33 +00:00
Mark Kettenis 7bf0983e94 * i386-linux-nat.c (i386_linux_dr_get): Change type of return
value to `unsigned long'.  Change type of `value' to `unsigned
long'.

long'.

`unsigned long'.

Mark Kettenis b9511b9a9a * i386-linux-nat.c (i386_linux_dr_get): Return 0 if ptrace call
fails instead of calling perror_with_name.  This should fix
debugging remote i386 targets with a native Linux/x86 GDB.  Add

	* 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.

	Conditionalize on HAVE_PTRACE_GETREGS.  Define stubs if
	HAVE_PTRACE_GETREGS isn't defined.

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.
