Gather operations that required implicit multiplication of the index vector (because of gather into an array of structure) will now do a more efficient vector multiplication or, if possible, use a larger stride in the gather instruction to avoid the multiplication (see #214) |
 |
Internal code cleanup (removal of dead code) to hit fewer compilation corner cases/errors. |

Buildsystem fixes for i686 and libmvec. |
