/* This header file is internal to BFD. It describes the internal

structures and functions used by the BFD generic linker, in case

any of the more specific linkers want to use or call them. Note

|
that some functions, such as _bfd_generic_link_hash_table_create,

|
are declared in libbfd.h, because they are expected to be widely
|
|
used. The functions and structures in this file will probably only

be used by a few files besides linker.c itself. In fact, this file

is not particularly complete; I have only put in the interfaces I

actually needed. */
