From 4d1464f294405a064d84e3d4f15c1ceff3639add Mon Sep 17 00:00:00 2001 From: Matthew Wahab Date: Tue, 7 Jun 2016 09:56:42 +0100 Subject: [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. --- gas/ChangeLog | 11 ++++++++ gas/config/tc-arm.c | 11 +++++--- gas/doc/c-arm.texi | 2 ++ gas/testsuite/gas/arm/armv8-a+ras.d | 55 +++++++++++++++++++++++++++++++++++++ gas/testsuite/gas/arm/armv8_2-a.d | 1 + 5 files changed, 76 insertions(+), 4 deletions(-) create mode 100644 gas/testsuite/gas/arm/armv8-a+ras.d (limited to 'gas') diff --git a/gas/ChangeLog b/gas/ChangeLog index ec30637..d41cd6d 100644 --- a/gas/ChangeLog +++ b/gas/ChangeLog @@ -1,3 +1,14 @@ +2016-06-07 Matthew Wahab + + * 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. + 2016-06-05 Trevor Saunders * itbl-parse.y (yyerror): Use modern argument declaration style. diff --git a/gas/config/tc-arm.c b/gas/config/tc-arm.c index d1114a1..5005343 100644 --- a/gas/config/tc-arm.c +++ b/gas/config/tc-arm.c @@ -223,8 +223,8 @@ static const arm_feature_set arm_ext_atomics = /* DSP instructions Tag_DSP_extension refers to. */ static const arm_feature_set arm_ext_dsp = ARM_FEATURE_CORE_LOW (ARM_EXT_V5E | ARM_EXT_V5ExP | ARM_EXT_V6_DSP);
