X-Git-Tag: basepoints/gcc-14~490
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=acff89c7d7b3af3553a4fb878b2fd767dd27d830;p=thirdparty%2Fgcc.git

i386: Robustify vec perm blend functions for TARGET_MMX_WITH_SSE

8-byte modes should be processed only for TARGET_MMX_WITH_SSE.

gcc/ChangeLog:

	* config/i386/i386-expand.cc (expand_vec_perm_pblendv):
	Handle 8-byte modes only with TARGET_MMX_WITH_SSE.
	(expand_vec_perm_2perm_pblendv): Ditto.
