*	math: remove STRICT_ASSIGN macro	Szabolcs Nagy	2013-09-06	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	gcc did not always drop excess precision according to c99 at assignments before version 4.5 even if -std=c99 was requested which caused badly broken mathematical functions on i386 when FLT_EVAL_METHOD!=0 but STRICT_ASSIGN was not used consistently and it is worked around for old compilers with -ffloat-store so it is no longer needed the new convention is to get the compiler respect c99 semantics and when excess precision is not harmful use float_t or double_t or to specialize code using FLT_EVAL_METHOD
*	math: fix underflow in exp*.c and long double handling in exp2l	Szabolcs Nagy	2013-09-05	1	-11/+10
\| \| \| \| \| \| \| \| \| \| \| \|	* don't care about inexact flag * use double_t and float_t (faster, smaller, more precise on x86) * exp: underflow when result is zero or subnormal and not -inf * exp2: underflow when result is zero or subnormal and not exact * expm1: underflow when result is zero or subnormal * expl: don't underflow on -inf * exp2: fix incorrect comment * expm1: simplify special case handling and overflow properly * expm1: cleanup final scaling and fix negative left shift ub (twopk)
*	math: expf.c cleanup	Szabolcs Nagy	2012-11-18	1	-9/+11
\| \| \| \| \| \|	similar to exp.c cleanup: use scalbnf, don't return excess precision, drop some optimizatoins. exp.c was changed to be more consistent with expf.c code.
*	math: exp.c clean up	Szabolcs Nagy	2012-11-17	1	-72/+49
\| \| \| \| \| \| \|	overflow and underflow was incorrect when the result was not stored. an optimization for the 0.5ln2 < \|x\| < 1.5ln2 domain was removed. did various cleanups around static constants and made the comments consistent with the code.
*	code cleanup of named constants	nsz	2012-03-19	1	-5/+4
\| \| \| \| \| \| \|	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).
*	fix loads of missing const in new libm, and some global vars (?!) in powl	Rich Felker	2012-03-18	1	-1/+1

*	first commit of the new libm!	Rich Felker	2012-03-13	1	-0/+157
	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.
