Even then, there are no attributes at the call site:
```
define dso_local void @call_func()() #1 !dbg !14 {
call void @func()(), !dbg !15
ret void, !dbg !16
}
```
On the other hand, if you add a `[[clang::always_inline]]` at the call site
(i.e. ` [[clang::always_inline]] func();`), you will get:
```
define dso_local void @call_func()() #1 !dbg !14 {
call void @func()() #4, !dbg !15
ret void, !dbg !16
}
attributes #4 = { alwaysinline }
```
This applies even to the existing `[[clang::always_inline]]`:
