--- Comment #7 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2011-07-29 11:49:30 UTC --- With this milestone the work for better support for widening multiplication is finished -- fir the case when MUL instruction is available. Similar work for the case when no hardware multiplier is available needs still to be done. The preferred approach in that case is to do the extension explicitely in libgcc prior to the multiplication. Respective code was already included in libgcc but dead because no one calls it up to now.
