------- Additional Comments From steven at gcc dot gnu dot org 2005-02-10 09:08 ------- The slowdown is probably some unfortunate icache effect - ccould be anything from alignment, the slightly larger instructions due to using r8 instead of rcx. I guess we should not care too much about such random effects that we cannot do anything about anyway. I'm going to see if it doesn't hurt on i686, and submit the patch if things look good.
