Subject: sincosl.c: Import from musl
X-Git-Tag: RELEASE-0.4~6
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=556819336cb66c5a40a33fe1c66a4fb8b355722a;p=unikraft%2Flibs%2Fnewlib.git

sincosl.c: Import from musl

Copied as is from the official musl git mirror
git://git.musl-libc.org/musl, commit 6fcb440d.

We only keep the non optimized definition since
all the long double math functions from newlib
are wrappers over double.
