Hi Tom, Matt, I'm working on a project that needs few coherent atomic operations (HSA mode: load, store, compare-and-swap) for std::atomic_uint in HCC. the attached patch implements atomic compare and swap for SI+ (untested). I tried to stay within what was available, but there are few issues that I was unsure how to address: 1.) it currently uses v2i32 for both input and output. This

Hi Christian, Ryan just reported to me that llvm-3.4 is no longer building on OS X Leopard (https://trac.macports.org/ticket/41548). It seems the issue is with a commit that you made back in April (referenced below) which added this to SIISelLowering.cpp: // Adjust the writemask in the node std::vector<SDValue> Ops; Ops.push_back(DAG.getTargetConstant(NewDmask, MVT::i32)); for (unsigned i = 1, e = Node->getNumOperands(); i != e; ++i) Ops.push_back(Node->getOperand(i)); Node = (MachineSDNode*)DAG.UpdateNodeOperand...

Hi, I've prepared patches for both LLVM and Clang to change the datalayout for R600. This may seem like a bold move, but I think it is warranted. R600/SI is a strange architecture in that it uses 64bit pointers but does not support 64 bit arithmetic except for load/store operations that roughly map onto getelementptr. The current datalayout for r600 includes n32:64, which is odd
