Yeah, I do @musllibc, FOSS & infosec stuff. But now is not the time for a mostly-/only-tech Twitter feed.

      This is one of the small things that processor vendors can do to make the life of compiler developers (and anyone writing low level code) much easier. "Where's that ISA document again?" becomes "Let's use google to find the instruction." ... and there was much rejoicing.https://twitter.com/alastair_d_reid/status/1014604328466878464 …

      The Arm formal spec has been available for download for a while now - but now it is available as a web page: https://developer.arm.com/products/architecture/a-profile/docs/ddi0596/latest/a64-base-instructions-alphabetic-order/adc … https://twitter.com/maver/status/1014501893043834881 …

      If only they could do away with the hideous 10MB page full of frames and js crap that takes 30+ seconds to load and 5+ seconds to respond to clicks and figure out how static html works...

      If you want a local copy, download the tarball from https://developer.arm.com/products/architecture/a-profile/exploration-tools …, all the HTML is in there plus XML if you want instruction encodings, etc.

      I really just want the convenience of typing arm + the insn mnemotic in Google and having a clean, fast, uncluttered page with all the info come up.

      If I cared that much about ARM specifically, yes I could doctor a local copy, but the effort needed to do that for everything I occasionally need doesn't scale.

          Meh. I like my ISA specs executable, testable, usable for formal verification of hardware, ... (Oh, ok, I'll admit it, I do have a soft spot for the one-page processor specs of my youth too.)
