- Subject: [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__
