We are likely to keep the llvm 3.4 port in FreeBSD for a while after 3.5 is released.  We've only removed the llvm 3.1 port a couple of months ago.  A few things still depend on LLVM 3.2, a few more on LLVM 3.3, so they're going to stay for a bit too.  The lack of any vague nods in the direction of API stability or deprecation mechanisms mean that there's always a moderate lag (2 years seems about normal) between an LLVM release being superseded and all dependent projects being upgraded (or, in some cases, abandoned).

This means that, if you have the time do to it, keeping the 3.4.x branch alive would likely be valuable.
