Subject: i386: Fix REDUC_SSE_SMINMAX_MODE mode conditions.
X-Git-Tag: misc/first-auto-changelog-9~134
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=d2fee90546d0f04595301af8f3786b8e1671814a;p=thirdparty%2Fgcc.git

i386: Fix REDUC_SSE_SMINMAX_MODE mode conditions.

V4SI, V8HI and V16QI modes of redux_<code>_scal_<mode> expander
expand with SSE2 instructions (PSRLDQ and PCMPGTx) so use
TARGET_SSE2 as relevant mode iterator codition.

	PR target/94494
	* config/i386/sse.md (REDUC_SSE_SMINMAX_MODE): Use TARGET_SSE2
	condition for V4SI, V8HI and V16QI modes.

testsuite/ChangeLog:

	PR target/94494
	* gcc.target/i386/pr94494.c: New test.
