--- Comment #2 from Ramana Radhakrishnan <ramana at gcc dot gnu.org> --- (In reply to Richard Earnshaw from comment #1) > Sounds like this might be confusion between weak definitions and weak > references. If we have a weak reference to the object, we cannot convert it > into a pc-relative expression, since that would mean we couldn't detect > NULL. However, if we have a non-weak reference to a weak object we can > replace that with a pc-relative addressing mode, _provided_ that we can > guarantee that the definition will appear in the same link unit (ie it's not > part of building a DSO).
