; Verify that pass 'Constant Hoisting' is not run on optnone functions.
; Without optnone, Pass 'Constant Hoisting' would firstly hoist
; constant 0xBEEBEEBEC, and then rebase the other constant
; (i.e. constant 0xBEEBEEBF4) with respect to the previous one.
; With optnone, we check that constants are not coalesced.
