SETCC Test case
When performing vector comparisons, the R600/SI back-end is tripping over an
LLVM assertion due to what appears to be an incorrectly lowered SETCC
operation:
llc:
/home/awatry/src/llvm/lib/CodeGen/SelectionDAG/LegalizeIntegerTypes.cpp:522:
llvm::SDValue llvm::DAGTypeLegalizer::PromoteIntRes_SETCC(llvm::SDNode*):
Assertion `SVT.isVector() == N->getOperand(0).getValueType().isVector() &&
"Vector compare must return a vector result!"' failed.
Test case is attached.
Note that this test case just verifies that the assembly compiles and doesn't
presume any specific expected output.
SETCC will need to be fixed in order for a number of OpenCL comparisons and
piglit tests to pass.</pre>
