[LLVMdev] R600/SI build failure on Leopard (Use of C++11)

[Jeremy Huddleston Sequoia]

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.UpdateNodeOperands(Node, Ops.data(), Ops.size());

That fails with Leopard's libstdc++ STL which does not a data method for std::vector.  This method was added in C++11:
http://www.cplusplus.com/reference/vector/vector/

Is llvm-3.4 now requiring a C++11 runtime?  If not, can we solve this a different way?

Thanks,
Jeremy
