Subject: LoongArch: Change loongarch_expand_vec_cmp()'s return type from bool to void.
X-Git-Tag: basepoints/gcc-15~576
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=1938d9d2bb8ecf84d2aa3c3ef2fb78ec19433057;p=thirdparty%2Fgcc.git

LoongArch: Change loongarch_expand_vec_cmp()'s return type from bool to void.

This function is always return true at the end of function implementation,
so the return value is useless.

gcc/ChangeLog:

	* config/loongarch/lasx.md (vec_cmp<mode><mode256_i>): Remove checking
	of loongarch_expand_vec_cmp()'s return value.
	(vec_cmpu<ILASX:mode><mode256_i>): Ditto.
	* config/loongarch/lsx.md (vec_cmp<mode><mode_i>): Ditto.
	(vec_cmpu<ILSX:mode><mode_i>): Ditto.
	* config/loongarch/loongarch-protos.h
	(loongarch_expand_vec_cmp): Change loongarch_expand_vec_cmp()'s return
	type from bool to void.
	* config/loongarch/loongarch.cc (loongarch_expand_vec_cmp): Ditto.
