| Subject: [PATCH] Automatically enable CRC instructions on supported ARMv8-A |
| CPUs. |
| |
| 2016-09-07 Richard Earnshaw <rearnsha@arm.com> |
| |
| * opcode/arm.h (ARM_ARCH_V8A_CRC): New architecture. |
| |
| 2016-09-07 Richard Earnshaw <rearnsha@arm.com> |
| |
| * config/tc-arm.c ((arm_cpus): Use ARM_ARCH_V8A_CRC for all |
| ARMv8-A CPUs except xgene1. |
