--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Yeah, -1U / 11 is 390451572, not 0.
11149         /* Convert -A / -B to A / B when the type is signed and overflow
is
11150            undefined.  */
11151         if ((!INTEGRAL_TYPE_P (type) || TYPE_OVERFLOW_UNDEFINED (type))
11152             && TREE_CODE (op0) == NEGATE_EXPR
11153             && negate_expr_p (op1))
needs to be adjusted the way Marc said.
