        PR middle-end/34070
        * fold-const.c (fold_binary): If testing for non-negative
        operands with tree_expr_nonnegative_warnv_p make sure to
        use op0 which has all (sign) conversions retained.

        * gcc.c-torture/execute/pr34070-1.c: New testcase.
        * gcc.c-torture/execute/pr34070-2.c: Likewise.

Added:
    trunk/gcc/testsuite/gcc.c-torture/execute/pr34070-1.c
