------- Comment #9 from rguenth at gcc dot gnu dot org 2008-10-15 21:47 ------- IMHO the fix for the tuplification bug(!) is to strip the ADDR_EXPR that is always present on op0 in split_constant_offset_1 so:
case ADDR_EXPR: { tree base, poffset; HOST_WIDE_INT pbitsize, pbitpos; enum machine_mode pmode; int punsignedp, pvolatilep; op0 = TREE_OPERAND (op0, 0); if (!handled_component_p (op0)) return false; -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=37573
