libgloss:
* arm/Makefile.in: Add newlib/libc/machine/arm to the include path if
newlib is present.
* arm/arm.h: Include acle-compat.h.
(THUMB_V7_V6M): Rename to ...
(PREFER_THUMB): This. Use ACLE macros __ARM_ARCH_ISA_ARM instead of
__ARM_ARCH_6M__ to decide whether to define it.
(THUMB1_ONLY): Define for Thumb-1 only targets.
(THUMB_V7M_V6M): Rename to ...
(THUMB_VXM): This. Defined based on __ARM_ARCH_ISA_ARM, excluding
ARMv7.
* arm/crt0.S: Use THUMB1_ONLY rather than __ARM_ARCH_6M__,
!__ARM_ARCH_ISA_ARM rather than THUMB_V7M_V6M for fp enabling, and
PREFER_THUMB rather than THUMB_V7_V6M. Rename other occurences of
THUMB_V7M_V6M to THUMB_VXM.
* arm/linux-crt0.c: Likewise.
* arm/redboot-crt0.S: Likewise.
* arm/swi.h: Likewise.
* arm/trap.S: Likewise.
newlib:
* libc/machine/arm/memcpy-stub.c: Use ACLE macros __ARM_ARCH_ISA_THUMB
and __ARM_ARCH_ISA_ARM to check for Thumb-2 only targets rather than
__ARM_ARCH and __ARM_ARCH_PROFILE.
* libc/machine/arm/memcpy.S: Likewise.
* libc/machine/arm/setjmp.S: Likewise for Thumb-1 only target and
include acle-compat.h.
* libc/machine/arm/strcmp.S: Likewise for Thumb-1 and Thumb-2 only
target and include acle-compat.h.
* libc/sys/arm/arm.h: Include acle-compat.h.
(THUMB_V7_V6M): Rename to ...
(PREFER_THUMB): This. Use ACLE macro __ARM_ARCH_ISA_ARM instead of
__ARM_ARCH_6M__ to decide whether to define it.
(THUMB1_ONLY): Define for Thumb-1 only targets.
(THUMB_V7M_V6M): Rename to ...
(THUMB_VXM): This. Defined based on __ARM_ARCH_ISA_ARM, excluding
ARMv7.
* libc/sys/arm/crt0.S: Use PREFER_THUMB rather than THUMB_V7_V6M and
rename THUMB_V7M_V6M into THUMB_VXM.
* libc/sys/arm/swi.h: Likewise.
This header was clearly copied from the common syscall.h and customized,
but the header comment is no longer accurate -- this isn't the general
file anymore.
* arm/configure.in: Revert previous fix and change host_makefile_frag
to calculate the absolute location of srcdir/../config/default.mh.
* arm/configure: Regenerated.
* arm/cpu-init/rdimon-aem.S: Disable for M class cores.
* arm/crt0.S: Don't call _rdimon_hw_init_hook for non-A class cores.
* arm/cpu-init/Makefile.in (CPU_INIT_OBJS): Use CFLAGS.
Thomas Klein <th.r.klein@web.de>
* arm/crt0.S: Manually set the target architecture
when compiling for Thumb1 on EABI targets.
Avoid v6-only Thumb-1 MOV instruction.

* arm/syscalls.c (_stat): Use _close
* arm/syscalls.c (struct poslog): Rename to...
(struct fdent): ... this.
(FILE_HANDLE_OFFSET): Remove.
(findslot): Return a struct fdent* if fd is valid, otherwise return NULL.
(newslot): New function.
(remap_handle): Remove.
(initialise_monitor_handles): Use stdout as fallback for stderr.
(wrap): Rename to...
(checkerror): ... this.
(_swiread): Use checkerror() for the return of SWI calls. Correct the use of r0.
(_read): Use findslot(). Return EBADF on bad handle.
(_swilseek): Call findslot(). Check for valid whence. Check for negative offset when using
SEEK_CUR, and check for overflow. Use checkerror(). Check *_Flen calls for errors.
(_swiwrite): Correct the use of r0.
(_write): Call findslot().
(_swiopen): Call findslot(). Check for valid flags. Use checkerror(). Call newslot().
Handle O_TRUNC, and O_WRONLY. Return index into openfiles[] for fd.
(_swiclose): Correct the use of r0.
(_close): Handle stderr == stdout case. Only reclaim handle if _swiclose succeeded.
(_getpid): Use __attribute__((unused)).
(_sbrk): Fix formatting.
(_swistat): New function.
(_stat): Call _swistat().
(_fstat): Call _swistat().
(_unlink): Correct the use of r0.
(isatty): Call finslot(). Correct the use of r0.
(_system): Call checkerror(). Correct the use of r0.
(_rename): Correct the use of r0.
* arm/Makefile.in: Add Linux syscall interface.
* arm/linux-crt0.S: New file.
* arm/linux-syscall.h: New file.
* arm/linux-syscalls0.S: New file.
* arm/linux-syscalls1.c: New file.
