This dot prefix is what exactly, is it an expectation of XCOFF in general? Seems like only some symbols will have it.

You say "for demangle" but it's not clear where that happens or if you mean remove it so that some other thing later can do it. If it does happen in this function perhaps clarify:
```
// Remove the dot prefix so that we can demangle it.
```
Now the link between action and purpose is clearer.
