; This test really wants to check that the resultant "cond_true" block only 
; has a single store in it, and that cond_true55 only has code to materialize 
; the constant and do a store.  We do *not* want something like this:
;
;LBB1_3: @cond_true
;        add r8, r0, r6
;        str r10, [r8, #+4]
