This functionality is subsumed by DataBufferLLVM, which is also more efficient since it will try to mmap. However, we don't yet support mmaping writable private sections, and in some cases we were using ReadFileContents and then modifying the buffer. To address that I've added a flag to the DataBufferLLVM methods that allow you to map privately, which disables the mmaping path entirely. Eventually we should teach DataBufferLLVM to use mmap with writable private, but that is orthogonal to this effort. Differential Revision: https://reviews.llvm.org/D30622 llvm-svn: 297095
