This chagne just renames some sys::Path methods to ensure they are not misused. The Path documentation now divides methods into two dimensions: Path/Disk and accessor/mutator. Path accessors and mutators only operate on the Path object itself without making any disk accesses. Disk accessors and mutators will also access or modify the file system. Because of the potentially destructive nature of disk mutators, it was decided that all such methods should end in the work "Disk" to ensure the user recognizes that the change will occur on the file system. This patch makes that change. The method name changes are: makeReadable -> makeReadableOnDisk makeWriteable -> makeWriteableOnDisk makeExecutable -> makeExecutableOnDisk setStatusInfo -> setStatusInfoOnDisk createDirectory -> createDirectoryOnDisk createFile -> createFileOnDisk createTemporaryFile -> createTemporaryFileOnDisk destroy -> eraseFromDisk rename -> renamePathOnDisk These changes pass the Linux Deja Gnu tests. llvm-svn: 22354
