Wow - we're on Hacker News again! Hello all, and thanks for the link and discussion! While we're here, we recently made some stats public: https://stats.compiler-explorer.com/ https://stats.compiler-explorer.com/ (spot the Hacker News spike!) General stuff: we're always looking for help; everything's open source on GH: https://github.com/compiler-explorer/ https://github.com/compiler-explorer/ (the base project, our cloud setup, all our build scripts, etc). The most valuable way to help us is with issues and PRs, or hang out on our Discord (https://discord.gg/zNNgyRKh https://discord.gg/zNNgyRKh). Then spread the word, and last we welcome sponsors on GH (https://github.com/sponsors/mattgodbolt https://github.com/sponsors/mattgodbolt) or Patreon (https://www.patreon.com/mattgodbolt https://www.patreon.com/mattgodbolt).

  Surprisingly accessible description of common optimizations; a useful survey for beginning compiler writers.

  He has a Patreon acct. For a few bucks, he will send you authentic Godbolt stickers for your laptop lids, for the ultimate in geek cred.

Thank you for making one of the coolest tools I found in the web in years.

Hi Matt. Thank you for such an excellent project. I'm pretty sure you already know of sharplab.io. A lot of us C# devs prefer it over Compiler Explorer for a bunch of reasons, but the main one is really the speed. My guess is that Sharplab gets it speed because it hooks directly into the JIT compiler itself. There is no overhead from touching disk or the linker.

  IIRC with .NET 7 we will be able to improve this as we can now dump the jit-generated assembly from official builds. .NET 7 will be officially released in a month or so. Currently C#/F#/VB support in Compiler Explorer relies on prejitting which has various issues.

  Confused, how is this related to C++ compilers? Edit: Oh wow I didn't realize the website does other languages, thanks!

    Godbolt does more than C++. I often share Java byte code snippets from there

      I wish it could also do the machine code version like on .NET languages. Maybe there is a way to plug hsdis into the workflow. EDIT: Actually there is already a ticket discussing this, https://github.com/compiler-explorer/compiler-explorer/issues/1364 https://github.com/compiler-explorer/compiler-explorer/issue...
