Add assembler support for ARMv8-M Mainline
2015-12-24 Thomas Preud'homme <thomas.preudhomme@arm.com>
bfd/
(tag_cpu_arch_combine): Adjust v4t_plus_v6_m and comb array to account
for new TAG_CPU_ARCH_V4T_PLUS_V6_M value. Deal with NULL values in
comb array.
binutils/
* readelf.c (arm_attr_tag_CPU_arch): Add ARMv8-M Mainline Tag_CPU_arch
value.
(arm_attr_tag_THUMB_ISA_use): Add ARMv8-M Mainline Tag_THUMB_ISA_use
value.
gas/
* config/tc-arm.c (arm_ext_m): Include ARMv8-M.
(arm_ext_v8m): New feature for ARMv8-M.
(arm_ext_atomics): New feature for ARMv8 atomics.
(do_tt): New encoding function for TT* instructions.
(insns): Add new entries for ARMv8-M specific instructions and
reorganize the ones shared by ARMv8-M Mainline and ARMv8-A.
(arm_archs): Define armv8-m.main architecture.
(cpu_arch_ver): Define ARM_ARCH_V8M_MAIN architecture version and
clarify the ordering rule.
(aeabi_set_public_attributes): Use TAG_CPU_ARCH_* macro to refer to
Tag_CPU_arch values for ARMv7e-M detection. Add logic to keep setting
Tag_CPU_arch to ARMv8-A for -march=all. Also set Tag_CPU_arch_profile
to 'A' if extension bit for atomic instructions is set, unless it is
ARMv8-M. Set Tag_THUMB_ISA_use to 3 for ARMv8-M. Set Tag_DIV_use to 0
for ARMv8-M Mainline.

(ARM_ARCH_V8M_MAIN): New architecture feature bitfield.
(ARM_ARCH_V8A_FP): Use ARM_EXT2_ATOMICS for features in second bitfield
and reindent.
(ARM_ARCH_V8A_SIMD): Likewise.
(ARM_ARCH_V8A_CRYPTOV1): Likewise.
(ARM_ARCH_V8_1A_FP): Use ARM_AEXT2_V8_1A to set second bitfield of
feature bits.

opcodes/
* arm-dis.c (arm_opcodes): Guard lda, ldab, ldaex, ldaexb, ldaexh, stl,
stlb, stlh, stlex, stlexb and stlexh by ARM_EXT2_ATOMICS instead of
ARM_EXT_V8.
(thumb32_opcodes): Add entries for wide ARMv8-M instructions.
