To do useful work, we want the machine to capture as long a sequence as possible.
WebJun 25, 2024 · In modern compilers it’s called “Peephole Optimizations”. Roughly speaking, compilers search for certain patterns and replace them with corresponding simplified expressions. In this blog post I’ll list some of them which I found in LLVM, GCC and .NET Core (CoreCLR) sources.
