> Can you please elaborate on "include embedded bitcasts of the function type"? It's a consequence of the AlwaysInliner where the callee gets replaced by the alias to a function, ie. @func_alias gets replaced by @func in the inline-calls.ll test.
Something like this where the alias changes the type from the original function:


```
@add1alias3 = alias float (float), bitcast (i32 (i32)* @add1 to float(float)*)
```
