From acb787b032ea5a84e8a5e94de0b0bf97523f8b47 Mon Sep 17 00:00:00 2001 From: Matthew Wahab Date: Thu, 19 Nov 2015 09:12:49 +0000 Subject: [PATCH] [AArch64] Add ARMv8.2 command line option and feature flag. ARMv8.2 is an architectural extension of ARMv8. This patch adds an architecture feature macro for ARMv8.2 to the binutils AArch64 target with GAS command line option -march=armv8.2-a. gas/ 2015-11-19 Matthew Wahab * config/tc-aarch64.c (aarch64_archs): Add "armv8.2-a". * doc/c-aarch64.texi (-march): Likewise. include/opcode/ 2015-11-19 Matthew Wahab * aarch64.h (AARCH64_FEATURE_V8_2): New.
