------- Comment #6 from jakub at gcc dot gnu dot org 2009-02-10 20:48 ------- This would mean -Os vs. -O2 gives different __alignof__(long long) values, I think that's a bad idea. I think a new option to disable dynamic realignment or at least do that if estimated stack size is <= 64 bits would be better.
