* Makefile.am (BFD32_LIBS): Add arange-set.lo.
(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.
