Introduce the `reentrant_capability` attribute, which may be specified alongside the `capability(..)` attribute to denote that the defined capability type is reentrant. Marking a capability as reentrant means that acquiring the same capability multiple times is safe, and does not produce warnings on attempted re-acquisition. The most significant changes required are plumbing to propagate if the attribute is present to a CapabilityExpr, and introducing ReentrancyDepth to the LockableFactEntry class.
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:
