        * config/i386/i386.c (ix86_expand_floorceildf_32): In ceil
        compensation use x2 += 1 instead of x2 -= -1 and when honoring
        signed zeros, do another copysign after the compensation.

        * gcc.target/i386/fpprec-1.c (x): Add 6 new constants.
        (expect_round, expect_rint, expect_floor, expect_ceil, expect_trunc):
        Add expected results for them.
