Thanks everyone.
I was able to compile it using the instructions Jose sent from this page:
http://mesa3d.org/llvmpipe.html.
However, I believe there's a typo in that page. In the text I've pasted
below, the highlighted RELEASE should be DEBUG.
Thanks again,
Shervin
For Windows you will need to build LLVM from source with MSVC or MINGW
(either natively or through cross compilers) and CMake, and set the LLVM
environment variable to the directory you installed it to. LLVM will be
statically linked, so when building on MSVC it needs to be built with a
matching CRT as Mesa, and you'll need to pass -DLLVM_USE_CRT_RELEASE=MTd
for debug and checked builds, -DLLVM_USE_CRT_RELEASE=MTd for profile and
release builds. You can build only the x86 target by passing
-DLLVM_TARGETS_TO_BUILD=X86 to cmake.
