  1. Your enthusiasm is appreciated, but it's good to...

    Your enthusiasm is appreciated, but it's good to be honest here.

    Apart from OpenMP support, GCC has polyhedral optimizations in graphite which are not yet part of LLVM. In theory this is a...
  2. The network in the building where the server is...

    The network in the building where the server is located (which I am guessing is some university campus somewhere) is down.
    People are aware of it but nothing can be done until the building network...
  3. Modules are already part of Clang. They are...

    Modules are already part of Clang. They are (thank Apple for this...) on track, as far as I can tell, to be part of C++14.
  4. I think it's a reasonable assumption. It's the...

    I think it's a reasonable assumption. It's the way I would bet.
    Apple has SPECIFICALLY stated that Swift code right now is in a state of flux, and they make no promises about backward compatibility....

    Please do share with us the details of this bizarre conspiracy..
    What exactly are the proprietary extensions Apple has added to LLVM?
  6. I agree those will be interesting, but the title...

    I agree those will be interesting, but the title does SAY that it's a GPU test...

    (Personally I'd call it a GL gaming test...

    Apple's first priority for the GPU is how it handles the visual...

    The point is that, for historical reasons, the GPU has been treated as a kind of weird peripheral, not as a kind of CPU that just happens to use a different ISA from the main CPU. Suppose you have a...

    No, he means back-ends. The whole point is that the front-end is language specific, and generates IR. a "neutral" middle part optimizes the IR. Then a back-end generates CPU specific machine...

    What EXACTLY are you claiming?
    Which of
    (a) Dart, RUN ON A BROWSER THAT SUPPORTS NATIVE DART is faster than JS or
    (b) Dart, COMPILED TO JS, is faster than JS?

    If (a), presumably that's only...
  11. I have no idea why you are so angry. Or for that...

    I have no idea why you are so angry. Or for that matter where you got your numbers from.

    Let's LOOK at the numbers:
    iPad Air at 1.4GHz. Geekbench single core rating is 1371:...
  12. To add to the (remarkably few) facts in this...

    To add to the (remarkably few) facts in this thread, x32 buys you about 10% in performance over x64. That's not bad, especially in contexts like phone and tablet where large address spaces are...
  13. I don't know what benchmarks you're looking at,...

    I don't know what benchmarks you're looking at, but the statements above strike me as very wrong.
    A more accurate claim, IMHO, would be that (averaged over a range of code) the Apple A7 has about...
  14. I don't think this tells us anything we didn't...

    I don't think this tells us anything we didn't know, primarily that AVX2 support is not yet ready for primetime. I expect the AVX2 cost metrics are far from accurate, hence the occasional regression...
  15. The problem with moving OpenGL forward is...

    The problem with moving OpenGL forward is POLITICAL as much as technical. There is a substantial contingent within Khronos for whom backwards compatibility matters more than anything else.
    THIS,...

    Apple has SAID NOTHING about the future plans for Metal. All they have said is that TODAY it supports only the A8. Obviously come September it will also support the A8. Who knows what happens after...
  17. I think you don't have a clue about the actual...

    I think you don't have a clue about the actual economics of the situation. I've no idea how you define "wide adoption" but ALREADY Crytek, Unity, Electronic Arts, and Epic Games have all announced...
  18. For Christ's sake, this "theorizing" is totally...

    For Christ's sake, this "theorizing" is totally retarded.
    The reason Apple is not releasing Swift as open-source today is absolutely obvious --- the syntax IS NOT YET FROZEN.
    Apple have said this...

    Oh for crying out loud. That's like asking for proof that the sky is blue. Reading anything by Matt Dillon makes this obvious.

    Go to the damn Dragonfly page. Let's look at eg:...

    Thanks for the tech update. I follow LLVM closely, but I only get to learn what's really happening in GCC from these sorts of posts.
    To my mind the real benefit from code reordering is not so much...
