    Not only will it show you how C/C++/Rust, etc... language statements map to CPU instructions, but it can also show you how CPUs execute those instructions! There are advanced views that show the various pipeline stages, execution ports, etc...

    E.g.: https://godbolt.org/#g:!((g:!((g:!((h:codeEditor,i:(filename...

    The right-most tab should show you the CPU execution pipeline

  • Ask HN: Going low-level – what to learn next?
    5 projects | news.ycombinator.com | 4 Jun 2024
    What you're basically after is some "Tooling and Methodology" studies for embedded. You've got the basics, but now you need to learn some more tools and the methods that make those tools really useful to the embedded/low-level context.

    Some simple things you can do:

    * Get yourself a suitable embedded development system - I would recommend anything ESP32'ish that suits your fancy such as a Liligo or Watchy ESP32-based watch, or PineTime if thats more up your alley - and then write some little apps for it.

    * Get to know Godbolt with a great deal of intimacy, just as a general approach to understanding what is going on:

    https://godbolt.org/

    * Invest a little workbench time in some of the various embedded frameworks out there - platformio, FreeRTOS, etc. and, very important: learn the Tooling And Methodology techniques that these frameworks manifest.

    * Invest some workbench time in the RETRO Computing Scene. Seriously, you can still learn extremely valuable principles of tooling and methodology from an 8-bit retro system from the 80's. Get your favourite platform, get all its tools onboard, engage with its community - you will learn a lot of things that are still entirely relevant, in spite of the changes over the decades.

    * Get into the F/OSS tooling/methdology flow - find software projects that are interesting to you, find their repositories, learn to clone and build and test locally, and so on. There are so many fantastic projects out there for which low-level skills can be developed/fostered. Get onboard with something that interests you.

    Good luck!

    I would say the compiler explorer[0] fits the definition perfectly. It may seem like a straightforward piece of software, but it has immensely changed the way people discuss and share knowledge around compilers and performance optimization.

    I regularly feel the impact on the quality of forum discussions. There's a lot less speculation about if "call X gets inlined", or "Y gets vectorized". Bold claims can be supported or disproven quickly by sharing a link.

    And then you have tools like llvm-mca[1] or uiCA[2], if you don't mind going into the weeds.

    At least on android arm64, looks like a `dmb ishst` is emitted after the constructor, which allows future loads to not need an explicit barrier. Removing `final` from the field causes that barrier to not be emitted.

    You said You won't get "extreme performance" from C++ because it is buried under the weight of decades of compatibility hacks.

    Now your whole comment is about vector behavior. You haven't talked about what 'decades of compatibility hacks' are holding back performance. Whatever behavior you want from a vector is not a language limitation.

    You could write your own vector and be done with it, although I'm still not sure what you mean, since once you reserve capacity a vector still doubles capacity when you overrun it. The reason this is never a performance obstacle is that if you're going to use more memory anyway, you reserve more up front. This is what any normal programmer does and they move on.

    Show what you mean here:

    https://godbolt.org/

    I've never used ISPC. It's somewhat interesting although since it's Intel focused of course it's not actually portable.

    I guess now the goal posts are shifting. First it was that "C++ as a language has performance limitations" now it's "rust has a vector that has a function I want and also I want SIMD stuff that doesn't exist. It does exist? not like that!"

    Try to stay on track. You said there were "decades of compatibility hacks" holding back C++ performance then you went down a rabbit hole that has nothing to do with supporting that.
