I built all of LLVM projects and ran the regression tests on Windows using Visual Studio, which are mentioned in http://clang.llvm.org/get_started.html.

1. Check out LLVM/Clang;
2. Run CMake to generate the Visual Studio solution and project files: % mkdir build % cd build % cmake -G "Visual Studio 12" ..\llvm An LLVM.sln file is created  in the build directory.
3. Open LLVM.sln in Visual Studio and build the "ALL_BUILD" project to build everything.
4. Build “check-all” project to run the regression tests. The report.cpp test failed during this step.
