Subject: x86: Use x constraint on KL patterns
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ede5f5224d55b84b9f186b288164df9c06fd85e7;p=test_jj.git

x86: Use x constraint on KL patterns

Since KL instructions have no AVX512 version, replace the "v" register
constraint with the "x" register constraint.

	PR target/105058
	* config/i386/sse.md (loadiwkey): Replace "v" with "x".
	(aes<aesklvariant>u8): Likewise.
