Godbolt is such an amazing tool, and amazing that it's free. For a random example from a few days ago, I wanted to understand how Rust compiles various approaches to doing pairwise addition between a f64 vector and a f32 vector: https://godbolt.org/z/9envsT https://godbolt.org/z/9envsT. Profiling can tell me which is fastest, but godbolt is really helpful for understanding why. (Fun fact I learned recently, after years of using it: Godbolt is named after its creator, Matt Godbolt [0]). [0] https://xania.org/MattGodbolt https://xania.org/MattGodbolt

Indeed, with such a splendid last name, it must take considerable humility to avoid naming all of his projects and even variables with it. I doubt I would be able to resist.

  "As you can see, step 3 of the Godbolt algorithm increments the fourth Godbolt variable by the gradient of the Godbolt network's Godbolt matrix..."

It is not named after him, at least now: the tool is called Compiler Explorer. The thing is that he originally served it from its domain so people use both interchangeably.

    It's on https://compiler-explorer.com/ https://compiler-explorer.com/ too. But it's too long to type, and so many weblinks point at godbolt.org that I've long since accepted that while its name is definitely "Compiler Explorer", folks will call it "godbolt" and type that into their browser. It's shorter and frankly when life gifts you a surname like mine, why not accept it? :)

      for fun it's also on godbo.lt

  And you can get stickers! No other sticker has quite the cachet of a Godbolt sticker.
