This is a proposed patch to enhance FileSystem.h to add functionality (getting and setting permission bits and mapping an unmapping files). This implementation follows the N3365 proposal regarding permission bits. This functionality is needed for my next patch which will implement llvm/include/Support/FileOutputBuffer.h which is needed by lld. -------------- next part -------------- A

Actually I was wrong. The Windows and UNIX implementation disagree on this point. I'm going to change it to match
