Subject: LoongArch: Drop vcond{,u} expanders.
X-Git-Tag: basepoints/gcc-16~6675
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0498f8bda1d08b8ed8100d759917792baf2da15f;p=thirdparty%2Fgcc.git

LoongArch: Drop vcond{,u} expanders.

Optabs vcond{,u} will be removed for GCC 15.  Since regtest shows no
fallout, dropping the expanders, now.

gcc/ChangeLog:

	PR target/114189
	* config/loongarch/lasx.md (vcondu<LASX:mode><ILASX:mode>): Delete.
	(vcond<LASX:mode><LASX_2:mode>): Likewise.
	* config/loongarch/lsx.md (vcondu<LSX:mode><ILSX:mode>): Likewise.
	(vcond<LSX:mode><LSX_2:mode>): Likewise.
