------- Comment #21 from matz at gcc dot gnu dot org 2009-02-25 18:04 ------- The question if such transformation is or isn't worthwhile is independent from the issue at hand (which is about the validity in the light of the new memory model). If you find a clearly pessimizing but valid transformation create a bug report.
