2015-04-18	math: fix pow(+-0,-inf) not to raise divbyzero flag	Szabolcs Nagy	-1/+1
	this reverts the commit f29fea00b5bc72d4b8abccba2bb1e312684d1fce which was based on a bug in C99 and POSIX and did not match IEEE-754 http://www.open-std.org/jtc1/sc22/wg14/www/docs/n1515.pdf
2015-03-11	math: add dummy implementations of 128 bit long double functions	Szabolcs Nagy	-1/+6
	This is in preparation for the aarch64 port only to have the long double math symbols available on ld128 platforms. The implementations should be fixed up later once we have proper tests for these functions. Added bigendian handling for ld128 bit manipulations too.
2012-03-27	math: fix a regression in powl and do some cleanups	nsz	-12/+11
	previously a division was accidentally turned into integer div (w = -i/NXT;) instead of long double div (w = -i; w /= NXT;)
2012-03-20	clean up powl.c	nsz	-92/+47
	fix special cases, use multiplication instead of scalbnl
2012-03-19	use scalbn or *2.0 instead of ldexp, fix fmal	nsz	-51/+52
	Some code assumed ldexp(x, 1) is faster than 2.0*x, but ldexp is a wrapper around scalbn which uses multiplications inside, so this optimization is wrong. This commit also fixes fmal which accidentally used ldexp instead of ldexpl loosing precision. There are various additional changes from the work-in-progress const cleanups.
2012-03-18	fix loads of missing const in new libm, and some global vars (?!) in powl	Rich Felker	-8/+8

2012-03-13	first commit of the new libm!	Rich Felker	-0/+562
	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.
