; This test contains two cast instructions that cannot be eliminated. If the
; input of the "test" function is negative, it should be correctly converted
; to a 32 bit version of the number with all upper 16 bits clear (ushort->uint
; involves no sign extension). Optimizing this to a single cast is invalid!
