* math: support platforms with limited FP rounding or exception supportChris Metcalf2012-05-171-0/+4
| | | | | | | | | | | For some tests, just claim that fetestexcept() always returns true, so the rest of the test can be compiled. For libm-test, provide known bogus values for unsupported rounding modes, so fesetround() will return failure. Elsewhere, just add some #ifdefs to avoid code that uses particular FP exceptions if the exceptions aren't supported.
* Fix FPU context handling in getcontext on x86-64.Ulrich Drepper2011-04-171-0/+48
fnstenv on x86-64 seems to clear the state. Work around.
