Your code is fast – if you're lucky
A technical exploration of how modern compilers optimize branchless code, specifically within a Quicksort implementation. The article provides code snippets demonstrating how to structure sorting networks to improve performance.
Why it matters
Understanding compiler optimization and branchless programming is essential for developers working on high-performance computing and low-latency software.
Recently, while I was working on an optimized Quicksort implementation, I came across a rather interesting quirk. Modern compilers (especially Clang) optimize loops using fast, branch-free instructions - provided you use the right programming style.
