 I meant "section symbols for LINK_ONCE_DISCARD sections only".  I suppose
I wasn't clear enough.  Due to the way these sections are handled, they
are not quite local, indeed.  Marking these symbols as global would allow
them to be looked up in the global symbol hash.

 There are no symbols within LINK_ONCE_DISCARD sections, normally.  They
carry a single template each when built by the c++ compiler.  Only the
section symbol gets referenced from them.
