glibc/math/libm-test-fma.inc
Tulio Magno Quites Machado Filho b297581acb 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.

Signed-off-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>
