LLVM-Makefiles

This is a set of GNU-makefiles for building LLVM / Clang on Windows using either MSVC's cl or clang-cl itself (edit Common.Windows and set USE_CLANG_CL = 0 or 1).

The reason I made these makefiles, was the utter slow build method the official CMake based method provided.
Using cl -MP ... to build is approximately 3 times faster than the generated Nmake Makefiles.

Besides, I do not know Cmake that well (and feel little motivated to learn that ugly syntax). Also, the obfuscated generated Makefiles Cmake generates makes it really hard to understand how it builds things.

Using GNU-make in dry-run mode (make -f Makefile.Windows -n), it is clearer what would be created without actually doing anything.

To use these Makefiles, select the Download ZIP button: screenshot

E.g. if the downloaded files ends up in c:\Users\John-Doe\Downloads, do:

  cd /D c:\Users\John-Doe\Downloads
  unzip.exe LLVM-Makefiles-master.zip

Then move all of the extracted LLVM-Makefiles-master\*.Windows files to your (for example) c:\MyProjects\LLVM-Project directory. And where you start GNU-make:

 c:\MyProjects\LLVM-Project> make -f Makefile.Windows
