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