Along the way, I learned about a modern compiler infrastructure named LLVM, which is a target-independent optimizer and code generator that has been used as a part of many compilers for different programming languages like Rust, Zig, or Haskell. While diving into LLVM’s aggressive optimization features, I have a humbling realizati...
