Bug #: 55001 Summary: Handle VEC_COND_EXPR in tree-vect-generic.c Classification: Unclassified Product: gcc Version: 4.8.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: middle-end AssignedTo: unassig...@gcc.gnu.org ReportedBy: gli...@gcc.gnu.org Created attachment 28497 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=28497 Old patch Hello, the code in tree-vect-generic.c to handle vector operations not provided by the target doesn't know VEC_COND_EXPR. That didn't matter when the vectorizer was the only producer, but front-ends are going to produce them as well any day now. Attaching the patch I was using when experimenting, but IIRC it wasn't in a state for submission, and its assumption that the first argument can't be an SSA_NAME or a constant is now wrong.
