Subject: [PATCH v2 2/3] LoongArch: Change loongarch_expand_vec_cmp()'s return type from bool to void.
Date: Fri, 15 Mar 2024 09:30:26 +0800	[thread overview]
Message-ID: <20240315013027.183888-3-panchenghui@loongson.cn> (raw)
In-Reply-To: <20240315013027.183888-1-panchenghui@loongson.cn>

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.
