* elf32-spu.c: Include libiberty.h.
	(struct spu_link_hash_table): Add local_stire, overlay_fixed, reserved,
	non_ovly_stub, spu_elf_load_ovl_mgr, spu_elf_open_overlay_script,
	spu_elf_relink, auto_overlay fields.
	(AUTO_OVERLAY, AUTO_RELINK, OVERLAY_RODATA): Define.
	(needs_ovl_stub): Flip test so that call to non-function warning
	is emitted during relocate_section rather than earlier.
	(spu_elf_check_vma): Stash --auto-overlay parameters, and clear
	auto_overlay if no section exceeds local store.
	(struct call_info): Add count, max_depth, is_pasted fields.
	(struct function_info): Add rodata, last_caller, call_count,
	depth, new visit flags.
	(insert_callee): Increment call count.
	(copy_callee): New function.
	(mark_functions_via_relocs): Investigate all reloc types to count
	possible function pointer stubs for --auto-overlay.  Track
	last_caller and increment function call_count.
	(pasted_function): Insert a "call" into call info for pasted section.
	(remove_cycles): Track max depth of calls.  Don't emit call graph
	pruning warning for --auto-overlay.
	(build_call_tree): Don't transfer_calls for --auto-overlay.
	Adjust remove_cycles call.
	(sort_calls, sort_lib, sort_bfds): New functions.
	(struct _mos_param, struct _uos_param, struct _cl_param): New.
	(mark_overlay_section, unmark_overlay_section): New functions.
	(collect_lib_sectios, auto_ovl_lib_functions): New functions.
	(collect_overlays, find_pasted_call): New functions.
	(sum_stack): Deal with is_pasted "calls".  Exit before printing
	when --auto-overlay.
	(spu_elf_auto_overlay): New function.
	(spu_elf_final_link): Call spu_elf_auto_overlay.
	* elf32-spu.h (spu_elf_check_vma): Update prototype.
ld/
	* emultempl/spuelf.em (auto_overlay, auto_overlay_file,
	auto_overlay_fixed, auto_overlay_reserved, my_argc, my_argv): New vars.

	(struct tflist, clean_tmp): Move.
	(new_tmp_file): New function, extracted from..
	(embedded_spu_file): ..here.
	(spu_elf_open_overlay_script, spu_elf_relink): New function.
	(gld${EMULATION_NAME}_finish): Pass a bunch of --auto-overlay params.
	Warn on --auto-overlay and zero local store.
	(gld${EMULATION_NAME}_choose_target): New function to stash argv.

	OPTION_SPU_OVERLAY_RODATA, OPTION_SPU_FIXED_SPACE,
	OPTION_SPU_RESERVED_SPACE, OPTION_SPU_NO_AUTO_OVERLAY): Define.

47f6dab9a3 Rewrite SPU overlay handling code. Put overlay calls stubs in the
overlays where possible.  Use a faster call stub, or optionally at
	compile time, a more compact stub.  Double size of _ovly_buf_table
	so that low bit of _ovly_table.buf can be used as a "present" bit.
	Reserve an extra _ovly_table entry for index zero.
