2011-10-12Optimize libmUlrich Drepper102-2753/+2418
libm is now somewhat integrated with gcc's -ffinite-math-only option and lots of the wrapper functions have been optimized.

2009-08-25Fix generic fdiml.Joseph Myers1-2/+2
2009-08-24Add ceil implementation for 64-bit machines.Ulrich Drepper1-0/+19
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.
