--- Comment #5 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Well, the problem is that -r is the only case where we get LDPR_PREVAILING_DEF
or IRONLY and the resulting symbol may be removed from the unit later.
We would need a new LDPR_PREVAILING_DEF_FOR_NOW or something like that to
represent the incremental nature of linking here, or we need a global flag in
GCC saying if incremental linking is supposed tohappen or not.
