; This testcase was written to demonstrate an instruction-selection problem,
; however it also happens to expose a limitation in the DAGCombiner's
; expression reassociation which causes it to miss opportunities for
; constant folding due to the intermediate adds having multiple uses.
; The Reassociate pass has similar limitations. If these limitations are
; fixed, the test commands above will need to be updated to expect fewer
; lea instructions.
