--- Comment #6 from lvqcl.mail at gmail dot com --- (In reply to Richard Biener from comment #2) > With i?86 I can confirm your observation but I don't see it fixed on trunk. Sorry, the GCC 6.x compiler that I downloaded was built with --with-arch=core2 option, so it implicitely enables ssse3. That's why I incorrectly thought that the regression was fixed.
