Comment # 1 on bug 72785 from 
Hm, I did think there would be some interest.

So but because the error had something to do with "llvm.SI.loop" and it said it
was in the "search" function there is only this one loop that can be the
trouble maker:

#pragma unroll
for (uint i=0; i<4; i++) 
...

So I removed that by manually unrolling it.
And indeed it gets a little further.
But then I get this error:

0x7fa839ae8160: i32 = ExternalSymbol'__muldi3'
Undefined function
UNREACHABLE executed at AMDGPUISelLowering.h:89!

With pyrit like in bug #64600 I get the same error, so... are the patches still
not in llvm 198401?

I guess I'll try with
http://cgit.freedesktop.org/~tstellar/llvm/log/?h=master-testing-si then.
