2015-02-08	math: fix __fpclassifyl(-0.0) for IEEE binary128	Szabolcs Nagy	1	-3/+2
	The sign bit was not cleared before checking for 0 so -0.0 was misclassified as FP_SUBNORMAL instead of FP_ZERO.
2014-10-08	always provide __fpclassifyl and __signbitl definitions	Rich Felker	1	-1/+4
	previously the external definitions of these functions were omitted on archs where long double is the same as double, since the code paths in the math.h macros which would call them are unreachable. however, even if they are unreachable, the definitions are still mandatory. omitting them is invalid C, and in the case of a non-optimizing compiler, will result in a link error.
2013-09-05	math: support invalid ld80 representations in fpclassify	Szabolcs Nagy	1	-2/+4
	apparently gnulib requires invalid long double representations to be handled correctly in printf so we classify them according to how the fpu treats them: bad inf is nan, bad nan is nan, bad normal is nan and bad subnormal/zero is minimal normal
2013-09-05	long double cleanup, initial commit	Szabolcs Nagy	1	-14/+14
	new ldshape union, ld128 support is kept, code that used the old ldshape union was rewritten (IEEEl2bits union of freebsd libm is not touched yet) ld80 __fpclassifyl no longer tries to handle invalid representation
2012-06-20	support ld80 pseudo-denormal invalid bit patterns; treat them as nan	Rich Felker	1	-2/+5
	this is silly, but it makes apps that read binary junk and interpret it as ld80 "safer", and it gets gnulib to stop replacing printf...
2012-03-13	first commit of the new libm!	Rich Felker	1	-13/+24
	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.
2011-06-30	fix error in previous ld80 fpclassify commit	Rich Felker	1	-1/+1

2011-06-30	catch invalid ld80 bit patterns and treat them as nan	Rich Felker	1	-2/+2
	this should not be necessary - the invalid bit patterns cannot be created except through type punning. however, some broken gnu software is passing them to printf and triggering dangerous stack-smashing, so let's catch them anyway...
2011-02-12	initial check-in, version 0.5.0v0.5.0	Rich Felker	1	-0/+16
