Why Do Peephole Optimizations Work?
Read OriginalThis technical article delves into peephole optimizations in modern compilers, explaining their transition from localized instruction sequences to SSA-based IRs like LLVM. It discusses the correctness criteria for such optimizations, arguing for refinement—making code more specific—rather than strict behavioral equivalence, and uses De Morgan's law as a concrete example.
