* 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.
(spu_before_allocation): Warn on --auto-overlay and existing overlays.
(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_AUTO_OVERLAY, OPTION_SPU_AUTO_RELINK,
OPTION_SPU_OVERLAY_RODATA, OPTION_SPU_FIXED_SPACE,
OPTION_SPU_RESERVED_SPACE, OPTION_SPU_NO_AUTO_OVERLAY): Define.
(PARSE_AND_LIST_LONGOPTS): Add entries for new options.
(PARSE_AND_LIST_OPTIONS): Likewise.
(PARSE_AND_LIST_ARGS_CASES): Likewise.
(LDEMUL_CHOOSE_TARGET): Define.
