2011-10-18Provide combined internal feholdexcept/fesetround interfaceUlrich Drepper
2011-10-18Start optimizing the use of the fenv interfaces in libm itselfUlrich Drepper
2011-10-15Optimize expUlrich Drepper
Add __exp*_finite optimizations and rewrite some wrappers.
2011-10-15Add parameter annotation to modfAndreas Jaeger
2011-10-12Optimize libmUlrich Drepper
libm is now somewhat integrated with gcc's -ffinite-math-only option and lots of the wrapper functions have been optimized.

2009-08-24Add ceil implementation for 64-bit machines.Ulrich Drepper
On 64-bit machines we should not split doubles into two 32 bit integer and handle the words separately. We have wide registers. This patch implements a 64-bit ceil version. Ideally all other functions will be converted over time.
