commit b297581acb66f80b513996c1580158b0fb12d469
Author: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
Date:   Mon Jan 14 17:54:44 2019 -0200

    Add XFAIL_ROUNDING_IBM128_LIBGCC to more fma() tests
    
    Ignore 16 errors in math/test-ldouble-fma and 4 errors in
    math/test-ildouble-fma when IBM 128-bit long double used.
    These errors are caused by spurious overflows from libgcc.
    
            * math/libm-test-fma.inc (fma_test_data): Set
            XFAIL_ROUNDING_IBM128_LIBGCC to more tests.
