When running the included testcase in llvm test/CodeGen/X86/vshift_split.ll
using the arm backend:

llvm-as < test/CodeGen/X86/vshift_split.ll | llc -march=arm            
llc:
/usr/src/openembedded/overo/tmp/work/armv7a-angstrom-linux-gnueabi/llvm2.6-2.5+svnr20090511-r0/trunk/lib/Target/ARM/ARMISelLowering.cpp:1565:
llvm::SDValue ExpandSRx(llvm::SDNode*, llvm::SelectionDAG&, const
llvm::ARMSubtarget*): Assertion `N->getValueType(0) == MVT::i64 &&
(N->getOpcode() == ISD::SRL || N->getOpcode() == ISD::SRA) && "Unknown shift to
lower!"' failed.
Stack dump:
