--- Comment #9 from Jakub Jelinek <jakub at gcc dot gnu.org> --- (In reply to Matthias Kretz from comment #8) > There seems to be a similar bug for vpsrlw and vpsllw. Do you need a > testcase? (It's hard to hit the bug... just had one occur on a Travis CI > build) I don't see how that is possible. Do you have at least objdump with the instructions (e.g. which exact operand it is), and what gcc options were used?
