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. |
