From 10c9892b66d56de0aab3fbaec3d59a0304dc0a21 Mon Sep 17 00:00:00 2001 From: Ramana Radhakrishnan Date: Thu, 17 Dec 2015 10:55:54 +0000 Subject: [Patch ARM] Fix build attributes for armv8-a in case of assembler files that contain no directives. There is currently a problem in the way in which we produce build attributes for simple assembler files that have armv8-a instructions. In these case we need to generate TAG_ISA_THUMB_Use to be Thumb-2 and set the architecture profile to be 'A' rather than not setting architecture profile to be 'A' and setting TAG_ISA_THUMB_Use to be Thumb-1. This is a pre-requisite for any v8-m patches that have been posted. arm-none-eabi gas testsuite run. no regressions. 2015-12-17 Ramana Radhakrishnan * gas/config/tc-arm.c (aeabi_set_public_attributes): Adjust TAG_ARCH_profile for armv8-a. * gas/testsuite/gas/arm/armv8a-automatic-hlt.d: New test. * gas/testsuite/gas/arm/armv8a-automatic-hlt.s: New test. * gas/testsuite/gas/arm/armv8a-automatic-lda.d: New test. * gas/testsuite/gas/arm/armv8a-automatic-lda.s: New test. --- include/opcode/arm.h | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'include') diff --git a/include/opcode/arm.h b/include/opcode/arm.h index 0814d80..daeb626 100644 --- a/include/opcode/arm.h +++ b/include/opcode/arm.h @@ -263,9 +263,10 @@ #define ARM_ANY ARM_FEATURE (-1, -1, 0) /* Any basic core. */ #define ARM_FEATURE_ALL ARM_FEATURE (-1, -1, -1)/* All CPU and FPU features. */ #define FPU_ANY_HARD ARM_FEATURE_COPROC (FPU_FPA | FPU_VFP_HARD | FPU_MAVERICK) -#define ARM_ARCH_THUMB2 ARM_FEATURE_CORE_LOW (ARM_EXT_V6T2 | ARM_EXT_V7 \ +#define ARM_ARCH_THUMB2 ARM_FEATURE_CORE_LOW (ARM_EXT_V6T2 | ARM_EXT_V7 \ | ARM_EXT_V7A | ARM_EXT_V7R \ - | ARM_EXT_V7M | ARM_EXT_DIV) + | ARM_EXT_V7M | ARM_EXT_DIV \ + | ARM_EXT_V8) /* v7-a+sec. */ #define ARM_ARCH_V7A_SEC ARM_FEATURE_CORE_LOW (ARM_AEXT_V7A | ARM_EXT_SEC) /* v7-a+mp+sec. */ -- cgit v1.1
