[llvm-dev] Help building llvm on freebsd 8.4

[Dimitry Andric via llvm-dev]

You cannot build any llvm or clang releases after 3.4 on FreeBSD 8.x natively, as it is not C++11 capable.  You need to use at least FreeBSD 10.x, which comes with clang 3.4.1 and libc++, providing C++11 support.

Also, please note that FreeBSD 8.x is officially EOLed as of August 1, 2015.

That said, you might have some success if you install a recent gcc port.  You will most likely have to manually apply https://svnweb.freebsd.org/base?view=revision&revision=297212 though, as I have not merged that back to FreeBSD 8.
