cxx-abi centralizes discussions and development surrounding the Itanium C++ ABI specification. The specification focuses on maintaining binary compatibility across different C++ compiler implementations. This project addresses ensuring code compiled with one compiler can interact with code compiled with another. It leverages a rigorous change process to carefully balance compatibility with necessary improvements and new features.
This repository provides a detailed specification for the Itanium C++ ABI, crucial for interoperability. It facilitates discussions on future ABI changes and bug fixes. The project employs a structured change process to manage proposals and ensure minimal impact on existing code.
- Binary Compatibility: Defines rules for ensuring code compiled with different compilers can work together.
- Future ABI Proposals: Allows for discussing and planning changes for future versions of the C++ ABI.
- Language Feature Implementation: Provides guidance on implementing new C++ language features with minimal backward impact.
- Bug Fixes: Facilitates the identification and resolution of bugs in the existing ABI specification.
- Exception Handling: Includes documentation on Compact Exception Tables for MIPS ABIs.
- Compiler Implementation: A resource for compilers to ensure interoperability.
- Community Collaboration: Provides a platform for open discussion and collaborative development.
The project is actively maintained with recent commits and ongoing discussions. The specification has a long history and benefits from a large community of contributors. The change process promotes careful consideration of proposed changes, fostering stability and reliability.
Developers and compiler implementers benefit from the cxx-abi repository by having a definitive guide to C++ ABI standards. It is valuable for ensuring interoperability between different C++ compilers and for planning future enhancements to the language. This resource is essential for anyone building systems that rely on binary compatibility in C++.
