--- Comment #24 from Richard Earnshaw <rearnsha at gcc dot gnu.org> --- (In reply to David Binderman from comment #22) > Is the optimization still worthwhile some 12 years later ? Almost certainly. Vector operations have become much better than they were at the time the patch went in, so it's probably even more worthwhile.
