    tree-optimization/119532 - ICE with fixed-point tail recursion

    The following disables tail recursion optimization when fixed-point
    types are involved as we cannot generate -1 for all fixed-point
    types.

            * tree-tailcall.cc (process_assignment): FAIL for fixed-point
            typed functions.

            * gcc.dg/torture/pr119532.c: New testcase.
