* math/libm-test.inc (fma_test_towardzero) [TEST_LDOUBLE &&
LDBL_MANT_DIG == 106]: Disable some tests.
(fma_test_downward) [TEST_LDOUBLE && LDBL_MANT_DIG == 106]:
Likewise.
(fma_test_upward) [TEST_LDOUBLE && LDBL_MANT_DIG == 106]:
Likewise.
[BZ #14871]
* sysdeps/ieee754/ldbl-128ibm/s_atanl.c (__atanl): Return the
input for small inputs. Return +/- pi/2 for large inputs.
