2018-09-12	reduce spurious inclusion of libc.h	Rich Felker	-1/+0
	libc.h was intended to be a header for access to global libc state and related interfaces, but ended up included all over the place because it was the way to get the weak_alias macro. most of the inclusions removed here are places where weak_alias was needed. a few were recently introduced for hidden. some go all the way back to when libc.h defined CANCELPT_BEGIN and _END, and all (wrongly implemented) cancellation points had to include it. remaining spurious users are mostly callers of the LOCK/UNLOCK macros and files that use the LFS64 macro to define the awful *64 aliases. in a few places, new inclusion of libc.h is added because several internal headers no longer implicitly include libc.h. declarations for __lockfile and __unlockfile are moved from libc.h to stdio_impl.h so that the latter does not need libc.h. putting them in libc.h made no sense at all, since the macros in stdio_impl.h are needed to use them correctly anyway.
2018-09-12	move lgamma-related internal declarations to libm.h	Rich Felker	-6/+0

2015-03-11	math: add dummy implementations of 128 bit long double functions	Szabolcs Nagy	-2/+8
	This is in preparation for the aarch64 port only to have the long double math symbols available on ld128 platforms. The implementations should be fixed up later once we have proper tests for these functions. Added bigendian handling for ld128 bit manipulations too.
2013-11-21	math: lgamma cleanup (simpler sin(pi*x) for the negative case)	Szabolcs Nagy	-60/+28
	* simplify sin_pi(x) (don't care about inexact here, the result is inexact anyway, and x is not so small to underflow) * in lgammal add the previously removed special case for x==1 and x==2 (to fix the sign of zero in downward rounding mode) * only define lgammal on supported long double platforms * change tgamma so the generated code is a bit smaller
2013-10-04	math: remove a useless assignment in lgammal found by clang analyzer	Szabolcs Nagy	-2/+2
	the issue was reported by Alexander Monakov
2013-09-05	math: remove libc.h include from libm.h	Szabolcs Nagy	-0/+1
	libc.h is only for weak_alias so include it directly where it is used
2013-09-05	math: fix remaining old long double code (erfl, fmal, lgammal, scalbnl)	Szabolcs Nagy	-28/+17
	in lgammal don't handle 1 and 2 specially, in fma use the new ldshape union instead of ld80 one.
2012-03-27	math: remove comment about aliasing lgamma as gamma	nsz	-0/+2
	It is probably not worth supporting gamma. (it was already deprecated in 4.3BSD)
2012-03-19	code cleanup of named constants	nsz	-26/+22
	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).
2012-03-16	other side of the signgam namespace fix: use the internal name	Rich Felker	-1/+3

2012-03-16	fix namespace issues for lgamma, etc.	Rich Felker	-8/+10
	standard functions cannot depend on nonstandard symbols
2012-03-15	in math.h make lgamma_r and non-double bessel _GNU_SOURCE only	nsz	-0/+1
	long double and float bessel functions are no longer xsi extensions
2012-03-13	first commit of the new libm!	Rich Felker	-0/+393
	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.
