The stmt is "_27 = BIT_FIELD_REF <vect__2.16_92, 32, POLY_INT_CST [96, 128]>". So "tree_to_uhwi (TREE_OPERAND (rhs1, 2))" failed. I plan to add a judgement before to make sure both TREE_OPERAND (rhs1, 1) and TREE_OPERAND (rhs1, 2) are INTEGER_CST. ^ permalink raw reply [flat|nested] 4+ messages in thread
