Rust to C Compiler Update: 96% Core Test Coverage!
2025-04-12
Significant progress has been made on a Rust to C compiler project, achieving a 95.9% core test pass rate and culminating in a presentation at Rust Week. The post details fixes for 128-bit integer intrinsics, checked arithmetic, and subslicing bugs. Improvements in C compiler compatibility are also discussed, along with a move towards a more memory-efficient internal IR. Challenges such as difficulties obtaining compilers for certain platforms are acknowledged, but the author remains committed to increasing C99 compliance and broader platform support. Future plans include completing a deep dive into Rust panics and developing a memory profiler.
