------- Additional Comments From bonzini at gcc dot gnu dot org 2005-04-26 17:35 ------- Another thing that CSE does is promoting paradoxical subregs to regs. On PowerPC at least, recursive calls of fold_rtx are almost ineffective except for this. Such promotion helps because equiv_constant does not look into subregs.
