[ARM] Add command line option for RAS extension.
This patch adds the architecture extension "+ras" to enable RAS
support. It is enabled by default for -march=armv8.2-a and available but
disabled by default for armv8-a and armv8.1-a.
gas/
* config/tc-arm.c (arm_ext_v8_2): Rename to arm_ext_ras.
(arm_ext_ras): Renamed from arm_ext_v8_2.
(insns): Update for arm_ext_v8_2 renaming.
(arm_extensions): Add "ras".
* doc/c-arm.texi (ARM Options): Add an entry for "ras".
* testsuite/gas/arm/armv8-a+ras.d: New.
* testsuite/gas/arm/armv8_2-a.d: Add explicit command line
options.
include/
* opcode/arm.h (ARM_EXT2_RAS): New. Also align preceding
entries.
(ARM_AEXT_V8_2A): Add ARM_EXT2_RAS.
opcodes/
* arm-dis.c (arm_opcodes): Replace ARM_EXT_V8_2A with
ARM_EXT_RAS in relevant entries.
