2020-08-05	math: new software sqrtl	Szabolcs Nagy	-1/+253
	same approach as in sqrt. sqrtl was broken on aarch64, riscv64 and s390x targets because of missing quad precision support and on m68k-sf because of missing ld80 sqrtl. this implementation is written for quad precision and then edited to make it work for both m68k and x86 style ld80 formats too, but it is not expected to be optimal for them. note: using fp instructions for the initial estimate when such instructions are available (e.g. double prec sqrt or rsqrt) is avoided because of fenv correctness.
2013-09-05	math: long double fix (use ldshape union)	Szabolcs Nagy	-3/+1
	* use new ldshape union consistently * add ld128 support to frexpl * simplify sqrtl comment (ld64 is not just arm)
2012-04-30	add C stub for sqrtl (already implemented in asm on i386 and x86_64)	Rich Felker	-0/+9

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