2011-10-15Optimize expUlrich Drepper7-154/+122
Add __exp*_finite optimizations and rewrite some wrappers.
2011-10-12Optimize libmUlrich Drepper94-2638/+1459
libm is now somewhat integrated with gcc's -ffinite-math-only option and lots of the wrapper functions have been optimized.

2011-09-07Check for finite/infinity parms in IBM Long Double 128 fmal( )Ulrich Drepper1-0/+39
This patch addresses some IBM Long Double 128 fmal () test-ldouble.out and test-ildoubl.out failures. If the ‘x’ and ‘y’ parameters are finite values and ‘z’ is infinity, the result of fmal () should be ‘z’ not NaN. Conflicts: ChangeLog

2009-08-24Add ceil implementation for 64-bit machines.Ulrich Drepper1-0/+67
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.
2009-05-29Fix errno for boundary conditions in 128-bit long double.Ulrich Drepper4-4/+32
Similar to the changes which went already in for the other formats, follow POSIX rules for errno.

After the last addition to the math test suite PPC routines haven't been adjusted so far.
