[Bug rtl-optimization/22563] [3.4/4.0/4.1 Regression] performance regression for gcc newer than 2.95



------- Comment #8 from hubicka at gcc dot gnu dot org  2005-11-03 22:54 -------
Actually the code 4.1 in comment #5 should execute faster on true i686. It is
longer and will trigger partial memory stalls on later chips.
