WG14 adopted the _ExtInt feature from Clang for C23, but renamed the type to be _BitInt. This patch does the vast majority of the work to rename _ExtInt to _BitInt, which accounts for most of its size. The new type is exposed in older C modes and all C++ modes as a conforming extension. However, there are functional changes worth calling out: * Deprecates _ExtInt with a fix-it to help users migrate to _BitInt. * Updates the mangling for the type. * Updates the documentation and adds a release note to warn users what is going on. * Adds new diagnostics for use of _BitInt to call out when it's used as a Clang extension or as a pre-C23 compatibility concern. * Adds new tests for the new diagnostic behaviors. I want to call out the ABI break specifically. We do not believe that this break will cause a significant imposition for early adopters of the feature, and so this is being done as a full break. If it turns out there are critical uses where recompilation is not an option for some reason, we can consider using ABI tags to ease the transition. |

//===----------------------------------------------------------------------===// // Clang Tools repository //===----------------------------------------------------------------------===// Welcome to the repository of extra Clang Tools. This repository holds tools that are developed as part of the LLVM compiler infrastructure project and the Clang frontend. These tools are kept in a separate "extra" repository to allow lighter weight checkouts of the core Clang codebase. This repository is only intended to be checked out inside of a full LLVM+Clang tree, and in the 'tools/extra' subdirectory of the Clang checkout. All discussion regarding Clang, Clang-based tools, and code in this repository should be held using the standard Clang mailing lists: http://lists.llvm.org/mailman/listinfo/cfe-dev Code review for this tree should take place on the standard Clang patch and commit lists: http://lists.llvm.org/mailman/listinfo/cfe-commits If you find a bug in these tools, please file it in the LLVM bug tracker: http://llvm.org/bugs/
