nit: This comment seems to be out of sync with other architecture ports, is that
on purpose?

The original comment was wrong, I meant to update all other architectures to be
like this but missed some - done now.

       ebx,  // address of first argument
       edi   // the target callable to be call
   };
   data->InitializePlatformSpecific(arraysize(registers), registers);
 }
