*	math: add dummy implementations of 128 bit long double functions	Szabolcs Nagy	2015-03-11	1	-0/+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.
*	math: long double fix (use ldshape union)	Szabolcs Nagy	2013-09-05	1	-4/+1
\| \| \| \| \| \|	* use new ldshape union consistently * add ld128 support to frexpl * simplify sqrtl comment (ld64 is not just arm)
*	math: use 0x1p-120f and 0x1p120f for tiny and huge values	Szabolcs Nagy	2012-12-16	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	previously 0x1p-1000 and 0x1p1000 was used for raising inexact exception like x+tiny (when x is big) or x+huge (when x is small) the rational is that these float consts are large enough (0x1p-120 + 1 raises inexact even on ld128 which has 113 mant bits) and float consts maybe smaller or easier to load on some platforms (on i386 this reduced the object file size by 4bytes in some cases)
*	math: rewrite inverse hyperbolic functions to be simpler/smaller	Szabolcs Nagy	2012-12-11	1	-48/+24
\| \| \| \| \| \| \| \| \| \| \| \|	modifications: * avoid unsigned->signed integer conversion * do not handle special cases when they work correctly anyway * more strict threshold values (0x1p26 instead of 0x1p28 etc) * smaller code, cleaner branching logic * same precision as the old code: acosh(x) has up to 2ulp error in [1,1.125] asinh(x) has up to 1.6ulp error in [0.125,0.5], [-0.5,-0.125] atanh(x) has up to 1.7ulp error in [0.125,0.5], [-0.5,-0.125]
*	code cleanup of named constants	nsz	2012-03-19	1	-4/+3
\| \| \| \| \| \| \|	zero, one, two, half are replaced by const literals The policy was to use the f suffix for float consts (1.0f), but don't use suffix for long double consts (these consts can be exactly represented as double).
*	first commit of the new libm!	Rich Felker	2012-03-13	1	-0/+63
	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.
