Nobody is proposing that LLVM moves off cmake, and nobody is proposing anything that's causing people using cmake more work. At the LLVM conference, I gave a lightning talk [1] about using GN [2] to build LLVM and clang. cmake is great for many use cases, but in my opinion local day-to-day development isn't one of them. So I wrote GN build files for LLVM and clang, enough to make ninja check-llvm check-clang_ _check-lld build everything needed for these three test suites and that all tests pass. This works on Linux, Mac, Win hosts targeting X86, ARM, AArch64. You can see them at [3].

I'm in favor of including the gn build files. Aside: build of gn itself failed for me on Ubuntu 14, link errors related to unsupported relocations, AFAICT this is just an incompatibility between the Debian filesystem downloaded and Ubuntu 14. Could you provide a release tarball of gn for a couple of key platforms? We provide prebuilts for GN now, see https://gn.googlesource.com/gn/#getting-started

Oh, I see, that works well. Thanks!
