--- Comment #16 from Andrew Pinski <pinskia at gcc dot gnu.org> 2012-01-05 00:35:27 UTC --- (In reply to comment #6) > OTOH, loop optimizer should detect invariant loads and move them out of the > loop. Just for someone else looking into this bug and thinking the last part of comment #6 was answered: It does move them out of the loop. Then the RA comes along and moves them back into the loop because of register pressure.
