*	math: fix rare underflow issue in fma	Szabolcs Nagy	2013-10-07	1	-2/+14
\| \| \| \| \|	the issue is described in commits 1e5eb73545ca6cfe8b918798835aaf6e07af5beb and ffd8ac2dd50f99c3c83d7d9d845df9874ec3e7d5
*	math: fix remaining old long double code (erfl, fmal, lgammal, scalbnl)	Szabolcs Nagy	2013-09-05	1	-14/+16
\| \| \| \| \|	in lgammal don't handle 1 and 2 specially, in fma use the new ldshape union instead of ld80 one.
*	math: add fma TODO comments about the underflow issue	Szabolcs Nagy	2013-05-19	1	-0/+2
\| \| \| \| \| \| \| \| \|	The underflow exception is not raised correctly in some cornercases (see previous fma commit), added comments with examples for fmaf, fmal and non-x86 fma. In fmaf store the result before returning so it has the correct precision when FLT_EVAL_METHOD!=0
*	math: use '#pragma STDC FENV_ACCESS ON' when fenv is accessed	Szabolcs Nagy	2012-11-13	1	-0/+1

*	use scalbn or *2.0 instead of ldexp, fix fmal	nsz	2012-03-19	1	-6/+6
\| \| \| \| \| \| \| \| \| \| \| \| \|	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.
*	fmal bug fix: nan input should not raise exception	nsz	2012-03-19	1	-4/+4

*	make fma and lrint functions build without full fenv support	Rich Felker	2012-03-16	1	-2/+12
\| \| \| \| \| \| \| \|	this is necessary to support archs where fenv is incomplete or unavailable (presently arm). fma, fmal, and the lrint family should work perfectly fine with this change; fmaf is slightly broken with respect to rounding as it depends on non-default rounding modes to do its work.
*	first commit of the new libm!	Rich Felker	2012-03-13	1	-0/+266
	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.
