LLVM 3.9.1 was just released. It’s time to build the new LLVM/Clang with MinGW. I managed to build the following things successfully: LLVM: the base for everything else Clang: C++ and C compilers, libClang, clang-format Clang Tools Extra: mostly because it contains clang-tidy LLD: the LLVM linker; haven’t played around with it yet, but it builds ;-) These do not build, even after some coercion: OpenMP: generally supports Windows, but not MinGW libc++: from what I could gather from the doc...
