Subject: [PATCH] LoongArch: Use __builtin_{fmax,fmaxf,fmin,fminf} with GCC >= 13
Date: Sat, 20 Aug 2022 16:43:44 +0800 [thread overview]
Message-ID: <9146983bcb2dc77fea7ab361f96005b1ce6dc698.camel@xry111.site> (raw)
GCC 13 compiles these built-ins to {fmax,fmin}.{s/d} instruction, use
them instead of the generic implementation.
Link: https://gcc.gnu.org/r13-2085
