ff5a090fb4 * Support code for enabling the new style linker for PA ELF.
* elfcode.h (swap_symbol_in, swap_symbol_out): Externalize.
	(elf_compute_section_file_positions): Pass link_info to
	the begin_write_processing hook.
	(bfd_elf_write_object_contents): Pass NULL for new link_info
	argument to final_write_processing hook.
	(elf_link_output_sym): Accept new "input_section" argument for
	the symbols's input section.  All callers changed.  Call the
	link_output_symbol_hook if it's defined.
	(elf_bfd_final_link): Call the final_write_processing hook if
	it's defined.
	* libelf.h (elf_backend_link_output_symbol_hook): Declare.
	(elf_backend_begin_write_processing): Add new "info" argument.
	(elf_backend_final_write_processing): Likewise.
	* elf32-target.h (elf_backend_link_output_symbol_hook): Provide
	a default definition.
	(elf32_bed): Add elf_backend_link_output_symbol_hook.
	* elf64-target.h: Likewise.

	* Major rework of the PA ELF code.  Uses the new style BFD
	linker, major cleanups.
	* hppa_stubs.h: Rewrite from scratch.  Much smaller and simpler.
	* elf32-hppa.h: Delete all symbol extension related code.
	(hppa_look_for_stubs_in_section): Delete decl.
	(elf32_hppa_size_stubs, elf32_hppa_build_stubs): New decls.
	* elf32-hppa.c: Symbol extension stuff moved form elf32-hppa.h
	into elf32-hppa.c.  Do not include aout64.h.
	(typdef hppa_stub_type): Delete.
	(elf32_hppa_stub_name_list_struct): Delete.
	(elf32_hppa_stub_description_struct): Delete.

	(hppa_elf_stub_finish, hppa_elf_stub_reloc): Delete.
	(hppa_elf_arg_reloc_needed): Renamed.  Simplify.
	(hppa_elf_build_linker_stub, hppa_elf_create_stub_sec): Delete.

	(elf32_hppa_backend_section_from_bfd_section): Delete.
	(NEW_INSTRUCTION): Delete.
	(CURRENT_STUB_OFFSET): Delete.
	(elf32_hppa_relocate_section): New function.
	(elf32_hppa_bfd_final_link_relocate): New function.
	(elf32_hppa_size_symext): New function.

	(elf32_hppa_size_stubs): New function.
	(linker, stub and argument hash tables): Add appropriate
	structures, definitions and functions to implement all three
	hash tables.
	(hppa_elf_relocate_insn): Don't need argument location information
	in this function.
	(add_entry_to_symext_chain): Accept a symbol's argument location
	information rather than the symbol itself.  All callers changed.
	(hppa_elf_gen_reloc_type): Simplify.
	(hppa_elf_set_section_contents): Stub section is no longer special.
	(hppa_elf_reloc): Greatly simplify.

3e80841e27 * elf32-hppa.c (hppa_elf_reloc): Remove DEFUN crud. Remove code
which is either commented out or ifdef'd out.  Add, update and
	clean comments.  Fix various indention and spacing problems.  Handle
	problems related to using "ble" to jump to a stub rather than "bl"
	(%r31 is trashed by "ble", but not by "bl").
	(NEW_INSTRUCTION): Put inside curly braces.
	(CURRENT_STUB_OFFSET): Fix indention problems.
	(hppa_elf_build_arg_reloc_stub): Fix indention and spacing problems.
	Add, update and clean comments.  Handle "ble" %r31 lossage problems.
	(hppa_elf_build_long_branch_stub): Likewise.
	(hppa_look_for_stubs_in_section): Likewise.
	(hppa_elf_stub_check): Remove obsolete function.

	* hppa_stubs.h: Add new instructions to deal with %r31 lossage
	problems.  Delete unused instructions.

3bca03362f elfcode.h (FILE_ALIGN_: Renamed from EALIGN, to avoid conflict with Ultrix
header files.

Also, lots of changes for PA elf and som support from Utah; see ChangeLog
for details.

e2a422b84c Merged in changes from Jeff Law and Pete Hoogenboom at Utah for PA ELF
support.  Compiles, not particularly well tested.  See ChangeLog for details.
