llvm ir file which reproduces the problem

-Mcpu=core2

The attached program gets the assertion failure

0x8268514: v1i8 = fp_to_sint 0x826815c
conversions: LegalizeDAG.cpp:6927:
llvm::SDValue<unnamed>::SelectionDAGLegalize::ScalarizeVectorOp(llvm::SDValue):
Assertion `0 && "Unknown vector operation in ScalarizeVectorOp!"' failed.

This also happens if fptosi is changed to fptoui.
