This PR uses the existing lifetime analysis for the `capture_by` attribute. The analysis is behind `-Wdangling-capture` warning and is disabled by default for now. Once it is found to be stable, it will be default enabled. Planned followup: - add implicit inference of this attribute on STL container methods like `std::vector::push_back`. - (consider) warning if capturing `X` cannot capture anything. It should be a reference, pointer or a view type. - refactoring temporary visitors and other related handlers. - start discussing `__global` vs `global` in the annotation in a separate PR. --------- Co-authored-by: Boaz Brickner <brickner@google.com>
C language Family Front-end
Welcome to Clang.
This is a compiler front-end for the C family of languages (C, 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 websites. Here are some pointers:
