Simdutf Can Now Be Used Without libc++ or libc++abi
2 days ago
- Simdutf can now be compiled without dependencies on libc++ or libc++abi, as demonstrated by a recent pull request.
- Removing libc++ dependencies enhances portability, simplifies cross-compilation, reduces binary size, and eases static linking.
- The removal involved two parts: libc++ (standard library) replaced via a custom stl_compat.h header, and libc++abi (ABI) addressed by replacing function-local statics and providing a shim for pure virtual functions.
- Extensive validation included running test suites and benchmarks in both normal and NO_LIBCXX modes, and verifying Ghostty's UTF-8 decoding performance remained unaffected.
- The contributor manually reviewed the entire diff, wrote a detailed PR description, and disclosed AI assistance while ensuring full human oversight.
- The Ghostty PR to use the new simdutf build has been merged, while the simdutf PR remains under review with positive initial feedback.
