------- Comment #2 from matz at gcc dot gnu dot org 2007-10-09 17:41 ------- I think this happens because gcc 4.3.x doesn't have fold_rtx_mem() and friends anymore since the introduction of fwprop.c. It formerly used to also lookup the address of the given MEMs, and hence perform this substitution. Now nothing looks at the address anymore (in cse). I don't yet know why fwprop doesn't do that. Paolo?
