bfd/ * elf32-spu.c (struct spu_link_hash_table): Add init, line_size_log2, num_lines_log2. (struct got_entry): Add br_addr. (struct call_info): Add priority. (struct function_info): Add lr_store and sp_adjust. (spu_elf_setup): Init line_size_log2 and num_lines_log2. (spu_elf_find_overlays): For soft-icache, mark any section within cache area as an overlay, and check that no other overlays exist. Look up icache overlay manager entry sym. (BRA_STUBS, BRA, BRASL): Define. (enum _stub_type): Replace ovl_stub with call_ovl_stub and br*_ovl_stub. (needs_ovl_stub): Adjust for soft-icache. Return priority encoded in branch insn. (count_stub, build_stub): Support soft-icache. (build_spuear_stubs, process_stubs): Adjust build_stub call. (spu_elf_size_stubs): Size soft-icache stubs. (overlay_index): New function. (spu_elf_build_stubs): Make static. Support soft-icache. (spu_elf_check_vma): Don't turn off auto_overlay if soft-icache. (find_function_stack_adjust): Save lr store and stack adjust insn offsets. (maybe_insert_function): Adjust find_function_stack_adjust call. (mark_functions_via_relocs): Retrieve priority. (remove_cycles): Only warn about pruned arcs when stack_analysis. (sort_calls): Sort by priority first. (mark_overlay_section): Ignore .ovl.init. (sum_stack): Only print when stack_analysis. (print_one_overlay_section): New function, extracted from.. (spu_elf_auto_overlay): ..here. Support soft-icache overlays. (spu_elf_stack_analysis): Only print when htab->stack_analysis. (spu_elf_final_link): Call spu_elf_stack_analysis for lrlive analysis. Call spu_elf_build_stubs. (spu_elf_relocate_section): For soft-icache encode overlay index into addresses. (spu_elf_output_symbol_hook): Support soft-icache. (spu_elf_modify_program_headers: Likewise. * elf32-spu.h (struct spu_elf_params): Add lrlive_analysis. Rename num_regions to num_lines. Add line_size and max_branch. (enum _ovly_flavour): Add ovly_soft_icache. (spu_elf_build_stubs): Delete. gas/ * config/tc-spu.c (md_pseudo_table): Add "brinfo". (brinfo): New var. (md_assemble): Poke brinfo into branch instructions. (spu_brinfo): New function. (md_apply_fix): Don't assume insn fields start off at zero, mask them to remove possible brinfo. ld/ * emultempl/spuelf.em (params): Init new fields. (num_lines_set, line_size_set, icache_mgr, icache_mgr_stream): New vars. (spu_place_special_section): Adjust placement for soft-icache. Pad soft-icache section to a fixed size. Clear addr_tree. (spu_elf_load_ovl_mgr): Support soft-icache. Map overlay manager sections a little more intelligently. (gld${EMULATION_NAME}_finish): Don't call spu_elf_build_stubs. (OPTION_SPU_NUM_LINES): Rename from OPTION_SPU_NUM_REGIONS. (OPTION_SPU_SOFT_ICACHE, OPTION_SPU_LINE_SIZE): Define. (OPTION_SPU_LRLIVE): Define. (PARSE_AND_LIST_LONGOPTS): Add new soft-icache options. (PARSE_AND_LIST_OPTIONS): Likewise.

(spu_icache.o_c): Add rule to build. (CLEANFILES): Zap temp files. (EXTRA_DIST): Add spu_icache.o_c. * Makefile.in: Regenerate. ld/testsuite/ * ld-spu/ovl.d: Allow for absolute branches in stubs. * ld-spu/ovl2.d: Likewise.

bfd/ * elf32-spu.h (struct spu_elf_params): ovly_flavour now only 1 bit. Add compact_stub. (emum _ovly_flavour): Delete ovly_compact, ovly_none. * elf32-spu.c (struct spu_link_hash_table): Replace ovly_load and ovly_return fields with ovly_entry[2]. Adjust all users.
