Subject: [AArch64] Define the macro __ARM_FP16_ARGS
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7bfa6b3f699a1e2810ae75c7f0c5485d71eaf324;p=clang

[AArch64] Define the macro __ARM_FP16_ARGS

The ACLE (ARM C Language Extensions) 2.0 defines that the predefined macro
__ARM_FP16_ARGS should be defined if __fp16 can be used as an argument and
result.

The support for __fp16 to be used as an argument and result is already
implemented for AArch64 so this change is just adding the missing macro.
