2012-03-17move nonstandard gamma() etc. to _GNU_SOURCE onlyRich Felker-4/+4
it's not even provided in the library at the moment, but could easily be provided with weak aliases if desired.
2012-03-17c++ seems to want some casts in the float representation-access macrosRich Felker-2/+2
2012-03-15in math.h make lgamma_r and non-double bessel _GNU_SOURCE onlynsz-20/+18
long double and float bessel functions are no longer xsi extensions
2012-03-15efficient sincos based on sin and cosnsz-0/+4
2012-03-13first commit of the new libm!Rich Felker-9/+64
thanks to the hard work of Szabolcs Nagy (nsz), identifying the best (from correctness and license standpoint) implementations from freebsd and openbsd and cleaning them up! musl should now fully support c99 float and long double math functions, and has near-complete complex math support. tgmath should also work (fully on gcc-compatible compilers, and mostly on any c99 compiler). based largely on commit 0376d44a890fea261506f1fc63833e7a686dca19 from nsz's libm git repo, with some additions (dummy versions of a few missing long double complex functions, etc.) by me. various cleanups still need to be made, including re-adding (if they're correct) some asm functions that were dropped.
2012-03-02fix nan/infinity macros in math.h, etc.Rich Felker-6/+8
the previous version not only failed to work in c++, but also failed to produce constant expressions, making the macros useless as initializers for objects of static storage duration. gcc 3.3 and later have builtins for these, which sadly seem to be the most "portable" solution. the alternative definitions produce exceptions (for NAN) and compiler warnings (for INFINITY) on newer versions of gcc.

thanks to Peter Mazinger (psm) for pointing many of these issues out and submitting a patch on which this commit is loosely based
