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. + * elf32-spu.c: (struct spu_link_hash_table): Delete a number of fields, + add new ones. + (struct got_entry): New. + (struct spu_stub_hash_entry): Delete. + (stub_hash_newfunc, spu_elf_link_hash_table_free): Delete. + (spu_elf_link_hash_table_create): Adjust for struct changes. + (spu_stub_name): Delete. + (spu_elf_find_overlays): Don't track sections from overlay regions. + Instead set ovl_buf number in spu elf section data. Error if + overlays in one region don't start at the same address. Adjust + for struct _spu_elf_section_data changes. + (SIZEOF_STUB1, SIZEOF_STUB2, ILA_79, ILA_78): Delete. + (OVL_STUB_SIZE, BRSL, LNOP, ILA): Define. + (needs_ovl_stub): Adjust for struct _spu_elf_section_data changes. + (enum _insn_type): New. + (count_stub, build_stub): New functions. + (allocate_spuear_stubs): Use count_stub. + (build_spuear_stubs): Use build_stub. + (populate_stubs, sort_stubs): Delete. + (process_stubs): New function. + (write_one_stub): Delete. + (spu_elf_size_stubs, spu_elf_build_stubs): Rewrite. + (alloc_stack_info): Adjust for struct _spu_elf_section_data changes. + (maybe_insert_function, check_function_ranges): Likewise. + (find_function, pasted_function, build_call_tree): Likewise. + (spu_elf_stack_analysis, spu_elf_modify_segment_map): Likewise. + (spu_elf_modify_program_headers): Likewise. + (interesting_section): Detect stub sections differently.
