------- Additional Comments From steven at gcc dot gnu dot org 2005-07-08 15:30 ------- Bug 19581 is about store motion that only loop.c currently does. Bug 19078 reports on a few tuning issues with BIV splitting in the unroller. Bug 11707 is about the lack of a constant propagation pass after loop2. Basically the question is here how late or early loop unrolling should happen.
