Remove `ContentCache::getBuffer`, which always returned a dereferenceable `MemoryBuffer*` and had a `bool*Invalid` out parameter, and replace it with: - `ContentCache::getBufferOrNone`, which returns `Optional<MemoryBufferRef>`. This is the new API that consumers should use. Later it could be renamed to `getBuffer`, but intentionally using a different name to root out any unexpected callers. - `ContentCache::getBufferPointer`, which returns `MemoryBuffer*` with "optional" semantics. This is `private` to avoid growing callers and `SourceManager` has temporarily been made a `friend` to access it. Later paches will update the transitive callers to not need a raw pointer, and eventually this will be deleted. No functionality change intended here.

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
