Sometimes the <<_bfd_link_add_symbols>> function must store
some information in the hash table entry to be used by the
- <<_bfd_final_link>> function. In such a case the <<creator>>

- hash table was created by an object file of the same format.

The <<_bfd_final_link>> routine must be prepared to handle a
hash entry without any extra information added by the
initialization function.
See <<ecoff_link_add_externals>> for an example of how to
- check the <<creator>> field before saving information (in this
+ check the output bfd before saving information (in this
