2013-09-05	math: long double inverse trigonometric cleanup (acosl, asinl, atanl, atan2l)	Szabolcs Nagy	-28/+22
	* added ld128 support from freebsd fdlibm (untested) * using new ldshape union instead of IEEEl2bits * inexact status flag is not supported
2013-08-15	math: clean up atan2.c	Szabolcs Nagy	-23/+13
	* remove volatile hacks * don't care about inexact flag for now (removed all the +-tiny) * fix atanl to raise underflow properly * remove signed int arithmetics * use pi/2 instead of pi_o_2 (gcc generates the same code, which is not correct, but it does not matter: we mainly care about nearest rounding)
2012-12-16	math: use 0x1p-120f and 0x1p120f for tiny and huge values	Szabolcs Nagy	-11/+11
	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)
2012-12-11	math: clean up inverse trigonometric functions	Szabolcs Nagy	-21/+19
	modifications: * avoid unsigned->signed conversions * removed various volatile hacks * use FORCE_EVAL when evaluating only for side-effects * factor out R() rational approximation instead of manual inline * __invtrigl.h now only provides __invtrigl_R, __pio2_hi and __pio2_lo * use 2pio2_hi, 2pio2_lo instead of pi_hi, pi_lo otherwise the logic is not changed, long double versions will need a revisit when a genaral long double cleanup happens
2012-11-14	math: ld80 invtrig cleanups	Szabolcs Nagy	-17/+15
	keeping only commonly used data in invtrigl
2012-03-19	code cleanup of named constants	nsz	-3/+2
	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).
2012-03-19	remove long double const workarounds	nsz	-9/+1
	Some long double consts were stored in two doubles as a workaround for x86_64 and i386 with the following comment: /* Long double constants are slow on these arches, and broken on i386. */ This is most likely old gcc bug related to the default x87 fpu precision setting (it's double instead of double extended on BSD).
2012-03-18	fix loads of missing const in new libm, and some global vars (?!) in powl	Rich Felker	-2/+2

2012-03-13	first commit of the new libm!	Rich Felker	-0/+114
	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.
