(expand_mult): ...here. (extract_high_half): New, split out from expand_mult_highpart. (expand_highpart_optab): Likewise. Don't clobber target prematurely. (expand_highpart): Evaluate the cost of a shift/add sequence, then see if any of the specialized optabs are cheaper. I still haven't identified the change that caused the linking.m error but possibly reverting Richard's change will fix it. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14663
