My GCM doesn't take 20% of my compile times last I checked but even so, V8 is gonna be in a special camp because they're comparing against a compiler that doesn't do much code motion. LLVM does a lot of code motion so that "20%" is still being paid by LLVM during their hoisting and local scheduling passes.
