+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.
