Subject: [PATCH] Automatically enable CRC instructions on supported ARMv8-A
|
||
|
|
CPUs.

|
||
|
|
|
||
|
|
* 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.
