--- Comment #4 from Martin Jambor <jamborm at gcc dot gnu.org> --- Created attachment 57397 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=57397&action=edit -fopt-info-vec before/after comparison (In reply to Richard Biener from comment #3) > A compare before/after the patch of -fopt-info-vec output might show the few > cases that are affected by the patch. I Hope I have not messed anything up. I have added -fopt-info-vec right after -fprofile-use into the spec config and then grepped the output for ':[^:]*:[^:]*: optimized'. Then I sorted (because the build was parallel) and compared the output and it seems there are quite a few *fewer* instances of vectorization happening.
