binutils-gdb/bfd/libbfd-in.h
Ian Lance Taylor f1cca64780 Support for link_order types which generate relocs in order to 
support -Ur in the linker.
	* linker.c (generic_link_add_symbol_list): Remove bitsize argument
	from call to _bfd_generic_link_add_one_symbol.
	(_bfd_generic_link_add_one_symbol): Remove bitsize argument.
	Don't pass bitsize to constructor call back.  Pass BFD_RELOC_CTOR
	instead of bitsize to add_to_set call back.
	(_bfd_generic_final_link): Account for link_order relocs when
	allocating space for relocations.  Handle them in link_order loop.
	(_bfd_generic_reloc_link_order): New function.
	(_bfd_default_link_order): If a reloc_link_order is seen here,
	abort.
	(_bfd_count_link_order_relocs): New function.
	* libbfd-in.h (_bfd_generic_link_add_one_symbol): Remove bitsize
	argument from declaration.
	(_bfd_generic_reloc_link_order): Declare.
	(_bfd_count_link_order_relocs): Declare.
	* libbfd.h: Rebuilt.
	* aoutx.h (aout_link_add_symbols): Remove bitsize argument from
	call to _bfd_generic_link_add_one_symbol.
	(NAME(aout,final_link)): Account for link_order relocs when
	allocating space for relocations.  Handle them after handling all
	input BFDs.
	(aout_link_reloc_link_order): New function.
	* ecoff.c (ecoff_link_add_externals): Remove bitsize argument from
	call to _bfd_generic_link_add_one_symbol.
	(ecoff_bfd_final_link): Account for link_order relocs when
	allocating space for relocations.  Handle them in link_order loop.
	(ecoff_link_write_external): Set the storage class of a defined
	linker created symbol based on the section it is in.  Correct
	bfd_link_hash_weak case to use .sc rather than .st.
	(ecoff_reloc_link_order): New function.
	* coff-alpha.c (alpha_bfd_reloc_type_lookup): Handle
	BFD_RELOC_CTOR.
	* coff-mips.c (mips_bfd_reloc_type_lookup): Likewise.
