Joseph Myers b55b28e657 Allow spurious underflow / inexact for ldbl-128ibm. A large number of the test-ldouble failures seen for ldbl-128ibm are spurious "underflow" and "inexact" exceptions. These arise from such exceptions in the underlying arithmetic; unlike other spurious exceptions from that arithmetic, they do not in general relate to cases where the returned result is also substantially inaccurate, are not so readily avoidable by appropriately conditional libgcc patches, and are widespread enough to be hard to handle through individual XFAILing of the affected tests. Thus, this patch documents relaxed accuracy goals for libm functions for IBM long double and makes libm-test.inc reflect these spurious exceptions in ldbl-128ibm arithmetic and always allow them in ldbl-128ibm testing (while still not allowing these exceptions to be missing where required to be present). Tested for powerpc. * manual/math.texi (Errors in Math Functions): Document relaxed accuracy goals for IBM long double. * math/libm-test.inc (test_exceptions): Always allow spurious "underflow" and "inexact" exceptions for IBM long double.		10 years ago
