I can now see how sloppy optimizations of AMD's drivers are...
They should be more aggressive with alloca promotion.

Code:
  // TODO: Have some sort of hint or other heuristics to guess occupancy based
  // on other factors..
  unsigned OccupancyHint
    = AMDGPU::getIntegerAttribute(F, "amdgpu-max-waves-per-eu", 0);
  if (OccupancyHint == 0)
    OccupancyHint = 7;

Code:
  // FIXME: There is no reason why we can't support larger arrays, we
  // are just being conservative for now.
  if (!AllocaTy ||
      AllocaTy->getElementType()->isVectorTy() ||
      AllocaTy->getNumElements() > 4 ||
      AllocaTy->getNumElements() < 2) {
    DEBUG(dbgs() << "  Cannot convert type to vector\n");
    return false;
  }

Oh, I'm right here. I was really focused on programming.
This LLVM thing is taking way too long, so I might take a break and work on the previous assembly version instead.

The new compiler for GCN is passing all the tests I created, but it seems to have some compatibility issues with GG's Equihash kernel. I hope I don't have to spend too much time rewriting the kernel...

It seems like I have to rewrite the whole kernel for the new compiler.
I had no idea LLVM would be so picky. Not a good indication for future AMD drivers.
I will take my time with this project and return to the old assembly version for now.
After wrestling with LLVM, GG's Equihash kernel looks so tiny...

Actually, I live not too far from AMD's headquarters. (It's commutable.)
Whether they want me or not is an entirely different question, though...

Now I think about it, the aforementioned incompatibility may have something to do with instruction alignments:

https://github.com/CLRX/CLRX-mirror/wiki/GcnTimings

None of this is officially documented, of course...

It must be the driver. Have you tried Crimson 16.9.2?

just FYI guys: running any of SGminer forks with CryptoNote on Win10 may produce 100% fan bug (occasionally fans jump to 100%) however it seems that single specific version: 16.11.4 fixes this problem.

EDIT: I'm talking Polaris cards here

indeed it does. there was no bois signature check in versions up to 16.12 (from 16.9.1?)

Hi Zawawa, something weird happening.

EDIT: nevermind, got it working, bat file issue...

On my two 6x RX470 rigs (Win 10), no issues running the miner.

However, on my rig with 2 R390X (Win 7 x64), when I launch the bat file, I see the yellow text appearing and it immediately goes to "Press a key to continue...". I don't get why it's not launching  Huh

Cheers
