        * c-convert.c (convert) [INTEGER_TYPE]: Drop ARG.  Don't pass ARG to
        ubsan_instrument_float_cast.  Fold EXPR.  Use NULL_TREE instead of
        NULL.

        * convert.c (convert_to_integer_1): Adjust call to
        ubsan_instrument_float_cast.  Use NULL_TREE instead of NULL.
        * ubsan.c (ubsan_instrument_float_cast): Drop the ARG parameter.  Use
        EXPR instead of ARG.
        * ubsan.h (ubsan_instrument_float_cast): Adjust declaration.

        * gcc.dg/ubsan/float-cast-overflow-atomic.c: New test.
