        PR target/88188
        * config/rs6000/rs6000.c (ccr_bit): Return -1 instead of assertion
        failures.
        (print_operand): Use REG_P instead of GET_CODE == REG.
        <case 'D'>: Also check CR_REGNO_P (REGNO (x)).
        <case 't'>: Likewise.  Remove GET_MODE check.
        * config/rs6000/rs6000.md (scc patterns): Assert ccr_bit didn't
        return -1.

        * gcc.target/powerpc/pr88188-2.c: New test.
