I've got a draft fix in my libclc repo on fdo.o. I've tested for regressions on Cedar (successfully), and I will test on SI with your 64-bit load patch asap (hopefully tonight, but we'll see).

I took a look at your libclc fix, and I realized that we can't use address space qualifiers in common code, because addrspace(1) may not mean global address space on all targets.

I think you might find that the optimizers are good enough to turn a .cl implementation into optimal code, but if not we may be have to move the LLVM IR implementations into target specific code.
