    maybe, but I have a strong feeling they know about those holes.

    Besides, this has made me reGoogle sh*t about LTO.

    So it sent me back to "GCC Internals Manual", which I either didn't see before...
  2. No. AFAIK they need easily testable small...

    No. AFAIK they need easily testable small example that exhibits the error. This means that I was expected to sit down, understand what's going on and reduce bazillion files to one of a few lines.

    Few more things, worth pointing out:

    1. LTO was experimented with before gcc-4.6, it was introduced with 4.6 and by first 4.7 it was declared as pretty complete, practically ready.

    From IIRC...
  4. Nope. That's exactly the environment that it...

    Nope. That's exactly the environment that it should do best in - where there are many small things getting compiled into many bigger and those bigger being recomplied now and then. Since LTO can see...
  5. I've used freshest gcc I could find. Last few gcc...

    I've used freshest gcc I could find. Last few gcc bumps in gentoo were mine, since I couldn't wait for an official ebuild. I recompiled everything so many times.

    And even with gcc-4.8.2 and...

    So when RAID-4/5/6/etc subsystem uses SSE to calculate Q syndrome, this means that whole that time on that core interrupts are disabled ?

    IIRC x86 has some trick that enables it to save extr<a...

    1. Nope. AFAIK you are talking about -fwhole program, that was just meant as an experiment or uverture of LTO.

    Loading all sources and processing them as one is precisely what LTO is trying to...
  8. 1. kernel, glibc and other non-standard packages...

    1. kernel, glibc and other non-standard packages are not that insignificant. Kernel doesn't link to anything outside in userland ( except perhaps that one link for getting accurate time, but that's...
  9. To all the people that have to avoid sugar and on...

    To all the people that have to avoid sugar and on periodic insuline shots (aka "diabetics") I say that I just downed large Coke over enormous piece of pie. And now I feel just fine.

    Also, I could...
  10. I'm not sure I would want that thing in kernel...

    I'm not sure I would want that thing in kernel just yet.

    kernel is a thin layer of code anyway. There is not much potential for sizeable speed gains there, even if LTO would work much better than...
  11. Mailbox Hardware Support

    I am configuring 3.14 right now and have stumbled in "Device Drivers" onto "Mailbox Hardware Support".

    It is described as a special FIFO system for sending messages on board between different...

    Meh, like usual. A few slight improvements on a synthetic test, with other results all over the place.

    Significant info would be how well is -flto optimisation performing and how many bugs were...
  13. I'd say it depends. For many applications I don't...

    I'd say it depends. For many applications I don't really need crypto everywhere, just on sensitive data.

    AES hardware is fine but it has its limits. Also, it means that data must go through CPU...
  14. how is crypto within fs meant to work ?

    I mean, is it meant to cryptoprotect whole FS or on dir and file basis ?
  15. I use it on my SDHC cards and USB sticks and I...

    I use it on my SDHC cards and USB sticks and I like it.

    Only thing missing is GRUB2's abiility to boot from it...

    +1

    This crippled my machine without warning. Those things renew my hate for Gentoo now and then, but on this particular instance I've had to sift through systemd's documentation and so have...

    So, how is this so much leaner than systemd ?

    And even if it is leaner in the sense of few kb of program image, why should this matter on anything even resembling useable machine with useable...

    Where do you see that complexity & bloat ?

    I see it as quite lean solution.
  19. Could you elaborate on that ? What exactly is so...

    Could you elaborate on that ? What exactly is so crappy in systemd ?

    I've installed it on gentoo a few days ago and am just making my way through the documentation.

    From what I have seen, I...

    You don't understand. 64-bit arch is not silver bullet in such energy conscious design. As said, 64-bit models will come out, but there will be niche for beefed-up 32-bit models within some...
