Can we host a prebuilt LLVM somewhere that we know works, and install that instead of installing the "real" LLVM? Alternatively, is there no PPA for llvm-3.4? Rust-CI demonstrates that travis is fine with adding a PPA and pulling from there, as that's how it gets the rust nightlies. |

LLVM advertises 3.4 PPAs as described here: http://llvm.org/apt/ I was unable to find them: https://travis-ci.org/alexcrichton/rust/builds/19665009 Hosting a prebuilt LLVM is possible, but it's the same difficulty of hosting a pre-built rust, which is currently in the works. |

I found a better solution, coming soon. |

It appears that LLVM has made another breaking change to our
PassWrapper.cppfile, causing our travis builds to break. This appears to be breaking more frequently than I had anticipated, which is unfortunate.I looked into installing and using LLVM 3.4 from their nightly repos (which is claimed to be stable), but apparently the llvm-3.4 package is missing from the repos, so it wasn't much of a success.
I'm curious what others' opinions on this are. I'm not a big fan of building LLVM all the time, but I also like having travis builds...
