Subject: [PATCH] [ARC] Add builtins for identifying floating point support
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=756b23a81c539aec9f8108cb8d6a6313aef02a99;p=gcc.git

[PATCH] [ARC] Add builtins for identifying floating point support

Currently for hard float we need to check for
 __ARC_FPU_SP__ || __ARC_FPU_DP__ and for soft float inverse of that.
So define single convenience macros for either cases.

	* config/arc/arc-c.c (arc_cpu_cpp_builtins): Add
          __arc_hard_float__, __ARC_HARD_FLOAT__,
          __arc_soft_float__, __ARC_SOFT_FLOAT__
