[llvm-commits] [llvm] r42264 - in /llvm/trunk: lib/CodeGen/SelectionDAG/LegalizeDAG.cpp test/CodeGen/X86/extractelement-from-arg.ll

New Revision: 42264

URL: http://llvm.org/viewvc/llvm-project?rev=42264&view=rev
Log:
Use the correct result value type instead of using getValueType(0)
in ExpandEXTRACT_VECTOR_ELT and SplitVectorOp. This fixes an abort
in the included testcase.
