Julia's libm is https://github.com/JuliaMath/openlibm (or http://openlibm.org/)
The do try merging latest from freebsd (msun), although it seems not
the very latest.
(see e.g. https://github.com/JuliaMath/openlibm/pull/118)
I did try installing the master git branch of openlibm on FreeBSD 11.1
it builds and passes all tests they have.
Does it make sense to contribute there more tests (if any --- they seem to have
quite a list), to clear
suspicions about precision?
