Hi all,

This is a simple patch to add more conditional macros defined ACLE 2.0.

aarch64-none-elf target is tested on the model, no new issues.

Is this Okay for trunk?


gcc/ChangeLog:

2014-11-17  Renlin Li  <Renlin.Li@arm.com>

     * config/aarch64/aarch64.h (TARGET_CPU_CPP_BUILTINS): Define 
__ARM_FP_FAST,
     __ARM_FEATURE_FMA, __ARM_FP, __ARM_FEATURE_NUMERIC_MAXMIN, 
__ARM_NEON_FP.
