2012-10-18Comment on slow compilation of math/test-tgmath2.cMarkus Trippelsdorf1-0/+3
The math/test-tgmath2.c testcase uses very long lines (>3 million), so it may take a while to compile it. See: http://llvm.org/bugs/show_bug.cgi?id=14106 and http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54402

2012-05-17math: support platforms with limited FP rounding or exception supportChris Metcalf5-0/+40
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.
2012-05-10Add a missing #include.Roland McGrath1-0/+1
2012-05-10Fix for logb/logbf/logbl (bugs 13954/13955/13956)Adhemerval Zanella1-0/+16
POSIX 2008 states that if the input for 'logb[f|l]' is a subnormal number it should be treated as if it were normalized. This means the implementation should calculate the log2 of the mantissa and add it to the subnormal exponent (-126 for float and -1022 for double and IBM long double). This patch takes care of that.

2012-05-02Use -frounding-math for math testsuiteAndreas Jaeger1-6/+8
We should tell GCC that we manipulate the rounding mode and therefore add -frounding-math to these files that call fesetround.
