--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> --- I thought graphite is done only after bitint lowering. At that point, there should be just <= MAX_FIXED_MODE_SIZE BITINT_TYPEs around in the IL, with the exception of loading SSA_NAMEs from memory in order to pass them to function calls, or undefined SSA_NAMEs, or usually TREE_ADDRESSABLE PARM_DECLs being converted to something else. Would be probably wise to punt on graphite optimizations on loops which have those larger SSA_NAMEs anywhere in the loop bodies. That said, ub4_0_17(D) is unsigned _BitInt(4).
