reduced test case from linux/drivers/ata/pata_optidma.c
Building ARM Linux (4.4-rc8) allmodconfig with clang-3.9-trunk, I seem to get
the same assertion in about a dozen files that use hardcoded I/O port numbers:
clang: /home/arnd/git/llvm/include/llvm/CodeGen/SelectionDAGNodes.h:632: const
llvm::SDValue& llvm::SDNode::getOperand(unsigned int) const: Assertion `Num <
NumOperands && "Invalid child # of SDNode!"' failed.
