3 ; The generation of a constant vector in the selection step resulted in
4 ; a VSPLAT, which, deeper in the expression tree had an unrelated BITCAST.
5 ; That bitcast was erroneously removed by the constant vector selection
6 ; function, and caused a selection error due to a type mismatch.
8 ; Make sure this compiles successfully.
