| # If we're compiling for MSVC then we, like most other distribution builders, |
| # switch to clang as the compiler. This'll allow us eventually to enable LTO |
| # amongst LLVM and rustc. Note that we only do this on MSVC as I don't think |
| # clang has an output mode compatible with MinGW that we need. If it does we |
| # should switch to clang for MinGW as well! |

| # Note that the LLVM installer is an NSIS installer |

| # Original downloaded here came from |
| # http://releases.llvm.org/7.0.0/LLVM-7.0.0-win64.exe |
| # That installer was run through `wine` on Linux and then the resulting |
| # installation directory (found in `$HOME/.wine/drive_c/Program Files/LLVM`) was |
| # packaged up into a tarball. We've had issues otherwise that the installer will |
| # randomly hang, provide not a lot of useful information, pollute global state, |
| # etc. In general the tarball is just more confined and easier to deal with when |
| # working with various CI environments. |
