[ARM] Add feature check for ARMv8.1 AdvSIMD instructions.
gas/
2016-03-04 Matthew Wahab <matthew.wahab@arm.com>
* config/gas/tc-arm.c (fpu_neon_ext_v8_1): Restrict to the ARMv8.1 RDMA
feature.
(record_feature_use): New.
(mark_feature_used): Use record_feature_use.
(do_neon_qrdmlah): New.
(insns): Use do_neon_qrdmlah for vqrdmlah and vqrdmlsh and
variants.
(arm_extensions): Put into alphabetical order. Re-indent "simd"
and "rdma" entries. Fix the incorrect merge value for "+rdma".
* testsuite/gas/arm/armv8-a+rdma-warning.d: New.
* testsuite/gas/arm/armv8-a+rdma.d: Add assembler command line options.
Make source file explicit.
* testsuite/gas/arm/armv8-a+rdma.l: New.
* testsuite/gas/arm/armv8-a+rdma.s: Remove .arch and .arch_extension
directives. Fix white-space.
* testsuite/gas/arm/armv8_1-a+simd.d: New.
include/opcode
2016-03-04 Matthew Wahab <matthew.wahab@arm.com>
* arm.h (ARM_ARCH_V8_1A): Add FPU_NEON_EXT_RDMA.
(ARM_CPU_HAS_FEATURE): Add comment.
