Subject: [PATCH 0/9] LoongArch: Use builtins with GCC >= 13
Date: Wed, 23 Nov 2022 10:38:48 +0800 [thread overview]
Message-ID: <20221123023851.751187-1-tangxiaolin@loongson.cn> (raw)
Patch 0001-0007:
GCC 13, LoongArch support builtins for {,l,ll}rint, logb,
use these built-ins instead of generic function implementation.
Patch 0008:
GCC 13, LoongArch support ___builtin_scalbn{,f} with -fno-math-errno,
but only "libm" can use -fno-math-errno in GLIBC, and scalbn is in libc
instead of libm because __printf_fp calls it. So inline assembler of
the scalbn functions is a better choice for LoongArch.
Patch 0009: Add LoongArch support for scalb[f].
