Yeah, I was also thinking that the use of a particular relocation makes it more
brittle. I think it is nice to check that func_exit is used without an argument
(unlike `__cyg_profile_func_enter_bare`). This can be done with the
`CHECK-NEXT` on the line that follows. Though I did not notice this kind of
parameter passing is already checked in
`llvm/test/Transforms/EntryExitInstrumenter/mcount.ll`, hence now I am not sure
how much value there is in this check.
I would not probably regret removing the line, but I'd like to try one more
thing:
```
; CHECK: {{.*}} %rdi
; CHECK-NEXT: callq __cyg_profile_func_exit
```
Will it blend?
