2013-09-06	math: remove STRICT_ASSIGN macro	Szabolcs Nagy	1	-1/+1
	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
2013-09-05	math: fix underflow in exp*.c and long double handling in exp2l	Szabolcs Nagy	1	-20/+20
	* 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)
2012-11-17	math: cleanup exp2.c exp2f.c and exp2l.c	Szabolcs Nagy	1	-31/+22
	* old code relied on sign extension on right shift * exp2l ld64 wrapper was wrong * use scalbn instead of bithacks
2012-03-18	fix loads of missing const in new libm, and some global vars (?!) in powl	Rich Felker	1	-1/+1

2012-03-13	first commit of the new libm!	Rich Felker	1	-0/+384
	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.
