* elf.c (get_program_header_size): Always add a PT_GNU_RELRO
segment for -z relro.
(_bfd_elf_map_sections_to_segments): Make a PT_GNU_RELRO
segment only when needed.
changing a relocation's offset. Adjust call to translate_reloc. Do
not add a fix record for a DIFF reloc. For other relocs, only add a
fix record if the translated target is in a different object file;
otherwise, just update the relocation. Call pin_internal_relocs when
updating a reloc but not when adding a fix record.
(translate_reloc): Get the target section from a new argument, not
from the relocation. Change check for relaxable sections to an
assertion. Compute separate offset adjustments for the base symbol
and the addend, and set the new relocation's addend correctly. Return
the new target section.
params. Change symidx to a size_t. Don't access past end
of symbol buffer.
(resolve_symbol): Add isymbuf param and use instead of
finfo->internal_syms.
(eval_symbol, evaluate_complex_relocation_symbols): Likewise.
(elf_link_input_bfd): Don't read symbols specially for
evaluate_complex_relocation_symbols.
(spu_elf_link_hash_table_create): Init new field.
(spu_elf_size_stubs): Store sorted stub syms in new htab field
rather than local var.
(spu_elf_build_stubs): Iterate over htab stubs rather than
hash traversal.
(struct stubarr): Delete.
(allocate_spuear_stubs, populate_stubs, write_one_stub): Adjust.
(BFD32_LIBS_CFILES): Add arange-set.c.
(SOURCE_HFILES): Add arange-set.h
(dwarf2.lo): Add dependency upon arange-set.h.
(arange-set.lo): New target.
* Makefile.in: Regenerate.
* arange-set.c: New file.
* arange-set.h: New file.
* dwarf2.c: Include arange-set.h.
(struct dwarf2_debug) Add new fields comp_unit_count and comp_unit_arange_set.
(struct comp_unit) Replace field arange with a new field arange_set.
(dwarf2_arange_set_allocate, dwarf2_arange_set_deallocate,
(dwarf2_combine_arange_value, dwarf2_arange_set_new,
(dwarf2_arange_set_with_value_new, dwarf2_comp_unit_arange_add): New
functions to utilize arange set in dwarf2.c.
(arange_add): Formatting change for a line longer than 80 characters.
(decode_line_info): Replace call target arange_add with
(dwarf2_comp_unit_arange_add.
(read_rangelist_insert_arange_list,
(read_rangelist_comp_unit_arange_add): New functions used as callbacks
for read_rangelist.
(read_rangelist): Change interface to accept a callback and data to
allow caller to select the action peformed on a new range list read.
(scan_unit_for_symbols): Use new interface of read_rangelist.
(parse_comp_unit): Create an arange set for each new comp unit. Use new
interface of read_rangelist. Replace call to arange_add with that to
dwarf2_comp_unit_arange_add.
(comp_unit_contains_address): Replace sequential search with a call to
arange_set_lookup_address, which can handles large set efficiently.
(stash_copy_local_aranges, stash_maybe_enable_arange_set,
(stash_find_nearest_line_fast): New functions maintaining and using a
valued global arange set for all compilation units to speed up
bfd_dwarf2_find_nearest_line.
(find_line): Use global arange set. Replace sequential search over all
compilation units with a call to stash_find_nearest_line_fast. Add
book keeping to count number of compilation units. Replace empty
arange list test with a call to arange_set_empty_p.
specific SOM sections for stabs if the regular ones are not found.
* som.h (struct somdata): Add a line_info field, to be used by som_find_nearest_line.
* som.c (som_find_nearest_line): Implement using the bfd stabs function above.
