commit 1253bc18ea989a3365d1409577c9045f8a399e06

    Change rs6000_const_f32_to_i32 return type.
    
    The function rs6000_const_f32_to_i32 called REAL_VALUE_TO_TARGET_SINGLE
    with a long long type and returns it.  This patch changes the type to long
    which is the proper type for REAL_VALUE_TO_TARGET_SINGLE.

            * config/rs6000/altivec.md (xxspltiw_v4sf): Change local variable
            value to to long.

            return type to long.
