[LLVMdev] Vector splitting vs widening
...0x23467e0, 0x23469e0, 0x23436a0 [ID=0]
Split node result: 0x2348620: v2f32 = extract_subvector 0x23435a0, 0x2346de0 [ID=0]
Widen node result 0: 0x2348820: v2i1 = setcc 0x2346ee0, 0x2348620, 0x23436a0 [ID=0]
llc: lib/CodeGen/SelectionDAG/LegalizeTypes.h:599: llvm::SDValue llvm::DAGTypeLegalizer::GetWidenedVector(llvm::SDValue): Assertion `WidenedOp.getNode() && "Operand wasn't widened?"' failed.
The problem is essentially the following: there are no vector f32 types (yet), so the <v4i1> = setcc <v4f32> node needs to be split and scalarized. The operand splitting seems...
