--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Why the
+ if (TREE_CODE (*op1_p) == INTEGER_CST)
+ *op1_p = fold_convert (unsigned_type_node, *op1_p);
+ else
+ *op1_p = build1 (NOP_EXPR, unsigned_type_node, *op1_p);
? Just change the convert to fold_convert... I hope the FE ensures that the
shift count has a sane type (some integral one).
