Hi Lauro,
This was caused by my fix for PR1529.
I'm currently considering the following patch, which fixes your attached
test case:
Index: lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp
===================================================================
RCS file: /var/cvs/llvm/llvm/lib/CodeGen/SelectionDAG/SelectionDAGISel.cpp,v

MVT::ValueType ElementVT;
NumRegisters = TLI.getVectorTypeBreakdown(VT, ElementVT, RegisterVT);
} else {
- RegisterVT = TLI.getTypeToTransformTo(VT);
+ RegisterVT = VT;
+ while (!TLI.isTypeLegal(RegisterVT))
+ RegisterVT = TLI.getTypeToTransformTo(RegisterVT);
NumRegisters = TLI.getNumRegisters(VT);
}
I'm looking to see if I can find a cleaner way to solve this.
