The information I've been able to find mostly discusses Linux support
for XLC 16. Any information about "some C++14 features"? I haven't
found any detail on that.
I am working toward being able to target this for JDK 12, but realize
that might not be reachable. Windows is already there, because of
VS2017 support. There are a couple of minor patches needed for gcc
and clang based builds; Linux-x64 and MacOSX-x64 have had a fair
amount of ad hoc testing. We (Oracle) only switched over the
Solaris/sparc builds to the necessary compiler version (Oracle Studio
12.6) very recently, and there are some issues still to be dealt with
there. And the currently used XLC is just not up to the change.
