From 29a4659015ca7044c2d425d32a0b828e0fbb5ac1 Mon Sep 17 00:00:00 2001 From: Richard Earnshaw Date: Wed, 7 Sep 2016 17:14:54 +0100 Subject: [PATCH] Automatically enable CRC instructions on supported ARMv8-A CPUs. 2016-09-07 Richard Earnshaw * opcode/arm.h (ARM_ARCH_V8A_CRC): New architecture. 2016-09-07 Richard Earnshaw * config/tc-arm.c ((arm_cpus): Use ARM_ARCH_V8A_CRC for all ARMv8-A CPUs except xgene1.
