Subject: Fix incorrect insn type to avoid ICE in memory attr auto-detection.
X-Git-Tag: basepoints/gcc-14~3386
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=916bec9a05ea522c81381e0c93590d46965d9c7b;p=thirdparty%2Fgcc.git

Fix incorrect insn type to avoid ICE in memory attr auto-detection.

Memory attribute auto detection will check operand 2 for type sselog,
and check operand 1 for type sselog1. For below 2 insns, there's no
operand 2. Change type to sselog1.

gcc/ChangeLog:

	PR target/107540
	* config/i386/sse.md (avx512f_movddup512<mask_name>): Change
	type from sselog to sselog1.
	(avx_movddup256<mask_name>): Ditto.

gcc/testsuite/ChangeLog:

	* gcc.target/i386/pr107540.c: New test.
