Commenting out the indicated line allows the vectorization to happen, but other simple replacements for that line don't allow vectorization (for example 'zr = r2'). No comment is written to the .vect file indicating why vectorization failed. -- Summary: Simple loop doesn't get vectorized Product: gcc Version: lno Status: UNCONFIRMED Severity: normal Priority: P2 Component: tree-optimization AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: tjw at omnigroup dot com CC: gcc-bugs at gcc dot gnu dot org GCC build triplet: powerpc-apple-darwin7.4.0 GCC host triplet: powerpc-apple-darwin7.4.0 GCC target triplet: powerpc-apple-darwin7.4.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16048
