this may be difficult, unfortunately. Some time ago, I tried to get an
answer to the question which macOS versions are supposed to be supported
by upstream LLVM and got nothing, despite the massive involvement of
Apple in the project. Still, it's certainly worth a try.
As a datapoint, both recent libsanitizer imports broke Solaris 11.3
bootstrap, which is still supported by GCC, but never was by LLVM. In
the first case, I managed to get a patch in to fix that (and a
non-trivial one at that), in the current case I even created the
breakage myself by (again) forgetting that upstream eventually gets
imported into GCC with its wider range of supported Solaris versions.
