gcc/
* config/arm/elf.h: Use __ARM_ARCH_ISA_THUMB and __ARM_ARCH_ISA_ARM to
decide whether to prevent some libgcc routines being included for some
multilibs rather than __ARM_ARCH_6M__ and add comment to indicate the
link between this condition and the one in
libgcc/config/arm/lib1func.S.
gcc/testsuite/
* lib/target-supports.exp (check_effective_target_arm_cortex_m): Use
__ARM_ARCH_ISA_ARM to test for Cortex-M devices.
libgcc/
* config/arm/bpabi-v6m.S: Clarify what architectures is the
implementation suitable for.
* config/arm/lib1funcs.S (__prefer_thumb__): Define among other cases
for all Thumb-1 only targets.
(NOT_ISA_TARGET_32BIT): Define for Thumb-1 only targets.
(THUMB_LDIV0): Test for NOT_ISA_TARGET_32BIT rather than
__ARM_ARCH_6M__.
(EQUIV): Likewise.
(ARM_FUNC_ALIAS): Likewise.
(umodsi3): Add check to __ARM_ARCH_ISA_THUMB != 1 to guard the idiv
version.
(modsi3): Likewise.
(clzsi2): Test for NOT_ISA_TARGET_32BIT rather than __ARM_ARCH_6M__.
(clzdi2): Likewise.
(ctzsi2): Likewise.
(L_interwork_call_via_rX): Test for __ARM_ARCH_ISA_ARM rather than
__ARM_ARCH_6M__ in guard for checking whether it is defined.
(final includes): Test for NOT_ISA_TARGET_32BIT rather than
__ARM_ARCH_6M__ and add comment to indicate the connection between
this condition and the one in gcc/config/arm/elf.h.
* config/arm/libunwind.S: Test for __ARM_ARCH_ISA_THUMB and
__ARM_ARCH_ISA_ARM rather than __ARM_ARCH_6M__.
* config/arm/t-softfp: Likewise.
