Consider the attached testcase. We're having currently:
./llc bugpoint-reduced-simplified.bc -mattr=+neon
llc: /home/asl/proj/llvm/src/lib/Target/ARM/Thumb2InstrInfo.cpp:417: int
llvm::rewriteT2FrameIndex(llvm::MachineInstr&, unsigned int, unsigned int, int,
const llvm::ARMBaseInstrInfo&): Assertion `AddrMode == ARMII::AddrMode5'
failed.
Also, the same file yields infinite loop in the codegen in ARM mode
(-march=armv7-elf).
