It is used in the NativeProcess/Thread plugins, but since those are new plugins only for AIX they dont need an #if AIX.

Thanks. Yes I see that the majority of existing calls are in, for example, lldb/source/Plugins/Process/Linux/NativeProcessLinux.cpp. And a lot are going via a Ptracewrapper that is also per platform.

This PosixFork is one of the few doing a direct call in generic code.

I am wondering if it should be `#if there is ptrace64` but I don't think so because this seems to be AIX specific. Even if it existed elsewhere I'd rather not silently use it without knowing how it behaves.
