Nicholas Nethercote reports on Rust compiler performance optimizations from his first month at Hexcat, focusing on improved span compression that reduces interning from 20-40% to ~1% in incremental builds. The new scheme also allows inline storage of the context field, reducing instruction counts by over 3% in best cases.
Background
Nicholas Nethercote is a well-known compiler performance engineer who has contributed extensively to Rust's compilation speed. He recently joined Hexcat to work full-time on Rust compiler performance.
