; 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.
