	* elf32-spu.g (struct spu_elf_params, enum _ovly_flavour): New.
	(spu_elf_setup): Declare.
	(spu_elf_create_sections, spu_elf_size_stubs): Update prototype.
	(spu_elf_build_stubs, spu_elf_check_vma): Likewise.
	* elf32-spu.c (struct spu_link_hash_table): Add "params". Remove
	various other fields now in "params".  Adjust code throughout.
	(struct call_info, struct function_info): Move earlier in file.
	(struct spu_elf_stack_info): Likewise.
	(spu_elf_setup): New function.
	(spu_elf_create_sections): Remove args other than "info".
	(spu_elf_size_stubs, spu_elf_build_stubs, spu_elf_check_vma): Likewise.
	(maybe_needs_stubs): Remove "output_bfd" arg.  Adjust all calls.
	(interesting_section): Similarly with "obfd" arg.
	(needs_ovl_stub): Adjust output_section test.
	(allocate_spuear_stubs): Likewise.
	(OVL_STUB_SIZE): Don't define.
	(ovl_stub_size): New function, use in place of OVL_STUB_SIZE.
	(build_stub): Test params->ovly_flavour rather than OVL_STUB_SIZE.
	(spu_elf_auto_overlay): Remove args other than "info".  Make use
	of size returned from spu_elf_load_ovl_mgr.
	(spu_elf_stack_analysis): Remove args other than "info".
	(spu_elf_relocate_section): Tidy setting of "ea".
ld/
	* emultempl/spuelf.em (params): New var, used instead of various others.
	Adjust use throughout file.
	(spu_after_open): Call spu_elf_setup.
	(spu_place_special_section): Tidy.
	(spu_elf_load_ovl_mgr): Return total size of sections loaded.  Move
	code setting overlay section alignment to..
	(spu_before_allocation): ..here.
