; There's a curious case where blockaddress constants may refer to functions
; outside of the function they're used in. There's a special bitcode function
; code, FUNC_CODE_BLOCKADDR_USERS, used to signify that this is the case.
; The intent of this test is two-fold:
; 1. Ensure we produce BLOCKADDR_USERS bitcode function code on the first fn,
; @repro, since @fun and @fun2 both refer to @repro via blockaddress
; constants.
; 2. Ensure we can round-trip serializing+desearlizing such case.
; CHECK: <FUNCTION_BLOCK
; CHECK: <BLOCKADDR_USERS op0=2 op1=1
; CHECK: <FUNCTION_BLOCK
; CHECK: <FUNCTION_BLOCK
