a5ccdad1fc * elfcode.h (elf_object_p): Rather than looking through an array
of architectures, get the ELF EM_xxx code from the backend
	information.  Let the generic ELF target match any EM_xxx code not
	matched by another ELF target.  Call elf_backend_object_p to let
	the backend do more checks and set global information.
	* libelf.h (struct elf_backend_data): Added elf_machine_code and
	elf_backend_object_p fields.
	(struct bfd_elf_arch_map): Removed.
	(bfd_elf_arch_map, bfd_elf_arch_map_size): Don't declare.
	* elf32-target.h, elf64-target.h: Initialize elf_machine_code
	field with ELF_MACHINE_CODE.  Initialize elf_backend_object_p
	field with elf_backend_object_p (if it is defined).
	* elf32-gen.c, elf32-hppa.c, elf32-i386.c, elf32-i860.c,
	elf32-m68k.c, elf32-m88k.c, elf32-mips.c, elf32-sparc.c,
	elf64-gen.c (ELF_MACHINE_CODE): Defined.
	* elf32-mips.c: Include ecoffswap.h to get ECOFF swapping
	routines.
	(mips_elf_object_p): Set the right machine number.
	(mips_elf_ecoff_debug_swap): Defined.
	(elf_backend_object_p): Defined to be mips_elf_object_p.
	(elf_backend_ecoff_debug_swap): Defined to be
	mips_elf_ecoff_debug_swap.
	* elf.c (bfd_elf_arch_map, bfd_elf_arch_map_size): Removed.

	* elf32-mips.c (elf_mips_howto_table): Don't complain on overflow
	for R_MIPS_26.  Correct overflow detection requires matching the
	upper four bits of the destination against the PC.  From Ted Lemon
	<mellon@pepper.ncd.com>.

	* elf32-hppa.c (elf_hppa_reloc_type_lookup): Return type
	should point to const data.

7218bb04b2 From Jeff Law and Pete Hoogenboom at Utah:
* elf32-hppa.h (hppa_elf_stub_finish): Add prototype.
(ELF32_HPPA_R_ARG_RELOC): Renamed without the ELF32 prefix
and moved into libhppa.h.  All references changed.
(ELF32_HPPA_R_CONSTANT, ELF32_HPPA_R_ADDEND): Likewise.
(get_opcode and opcode defines): Move into libhppa.h
* elf32-hppa.c (hppa_elf_insn2fmt): Rename and move info libhppa.h.
* libhppa.h (HPPA_R_*): Moved here.  Reformatted slightly to make for easier
reading.
(get_opcode): Moved here.  FIXME! this really should be a C function
inside the opcode library!
(bfd_hppa_insn2fmt): Likewise.

* targets.c (target_vector): Enable elf32-hppa vector.

* elf32-hppa.c (hppa_elf_get_section_contents): Add new comments and clarify
existing comments.  Do not use DEFUN to declare this function.  Fix numerous
indention problems.  Correctly handle cases where symbol extension section may
need to be read from disk, read from memory, or built then read from memory.

* elf32-hppa.h: Reformat with gnu-indent and hand fix numerous
formatting and indention problems gnu-indent can not handle.
Clarify some comments about relocation types.  Comment basic
relocation "classes".  Group PARAM declarations together.
(HPPA_SXT_{NULL, SYMNDX, RG_RELOC}): Make members of a new
enumerated type rather than #defines.

d9ad93bce5 More patches from Jeff Law, plus a little cleanup of my own.
These changes separate PA-SOM support from PA-ELF support.
A sun4-x-hppaosf assembler can now be built.

* elf32-hppa.c (elf_hppa_howto_table): Now static.
(symext_rootP, symext_lastP, global_value, GOT_value, global_symbol,
global_sym_defined, symextn_contents, symextn_contents_real_size,
elf_hppa_stub_rootP, elf32_hppa_symextn_map, elf32_hppa_symextn_map_size): Rely
on default initialization.
(hppa_elf_gen_reloc_type): Macro "UNDEFINED" doesn't need a trailing semicolon.
(hppa_look_for_stubs_in_section): Introduce temporaries to make code more
readable in 80 columns.

* libhppa.h (all functions): Now inline under GNU C.

* elf32-hppa.c (AR_WARN): Give argument which caused the invalid argument
relocation.
(AR_UNIMP): Delete unused macro.
(hppa_elf_set_section_contents): Always return a value.
(elf32_hppa_backend_table_processing): Likewise.
(elf32_hppa_backend_section_processing: Likewise.

* som.c: New file containing SOM specific code extracted from hppa.c

* som.h: New file containing SOM specific code extracted from libhppa.h

* hppa.c: Deleted.

* libhppa.h: Delete SOM specific code.  Add generic PA code which can be shared
by both SOM and ELF backends.

* Makefile.in: Replace hppa.c with som.c.  elf32-hppa.o depends on libhppa.h
now.

* configure.in (hppa_vec): Needs som.o module instead of hppa.o.

* elf32-hppa.c: Include libhppa.h.  Do not define BYTES_IN_WORD.

* elf32-hppa.h (hppa_reloc_field_selector_type): Delete now lives in libhppa.h.
(hppa_reloc_field_selector_type_alt): Likewise.

* elf32-hppa.c (hppa_elf_relocate_unwind_table): Delete unused variables.
(elf_hppa_reloc_type_lookup): Likewise.
(elf_hppa_tc_make_sections): Likewise.
(hppa_elf_arg_reloc_needed_p): Likewise.
(hppa_elf_build_long_branch_stub): Likewise.
(elf_reloc_map): Delete, no longer used.
(elf_hppa_reloc_map): Likewise.
(elf32_hppa_symextn_map_max_size): Likewise.
(elf32_hppa_get_sym_extn): Abort if type is bogus.

* elf32-hppa.c (elf32_hppa_backend_fake_sections): Add processing
of the .hppa_unwind section.
