2016-08-30	math: fix 128bit long double inverse trigonometric functions	Szabolcs Nagy	-1/+1
	there was a copy paste error that could cause large ulp errors in atan2l, atanl, asinl and acosl on aarch64, mips64 and mipsn32. (the implementation is from freebsd fdlibm, but the tail end of the polynomial was wrong. 128 bit long double functions are not yet tested so this went undetected.)
2013-09-05	math: long double inverse trigonometric cleanup (acosl, asinl, atanl, atan2l)	Szabolcs Nagy	-1/+33
	* added ld128 support from freebsd fdlibm (untested) * using new ldshape union instead of IEEEl2bits * inexact status flag is not supported
2012-12-11	math: clean up inverse trigonometric functions	Szabolcs Nagy	-31/+10
	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	-36/+6
	keeping only commonly used data in invtrigl
2012-03-13	first commit of the new libm!	Rich Felker	-0/+82
	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.
