A compiler-optimization study shows signed 32-bit division by constants can often use a 33-bit multiplier without compilers' extra correction step, shortening the dependency chain on 64-bit systems. Benchmarks on Intel and Apple processors report lower latency for affected divisors and a branchless fastmod update.
