Summary: Many methods in Sema take a `bool Diagnose` parameter. Examples of such methods include `Sema::FindDeallocationFunction` and `Sema::SpecialMemberIsTrivial`. Calling these methods with `Diagnose = false` allows callers to, for instance, check for the existence of a deallocation function, without that check resulting in error diagnostics being emitted if no matching deallocation function exists. Add a similar `bool Diagnose` to the `Sema::FindAllocationFunctions` method, so that checks for the existence of allocation functions can be made without triggering error diagnostics. This allows `SemaCoroutine.cpp`, in its implementation of the Coroutines TS, to check for the existence of a particular `operator new` overload, but then without error fall back to a default `operator new` if no matching overload exists.

//===----------------------------------------------------------------------===// // 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/
