2014-01-28	Add .gdb_index version 7 support.	Cary Coutant	1	-3/+4
	This patch adds support for .gdb_index version 7, which adds several flag bits to the symbol index. It also fixes a problem where it did not handle compressed debug sections correctly. Tested with a google/gcc-4_8 branch compiler, which supports the -ggnu-pubnames option to generate .debug_gnu_pubnames/pubtypes tables. (We will submit that patch to GCC when stage 1 reopens.) 2014-01-28 Cary Coutant <ccoutant@google.com> * gold/dwarf_reader.cc: include <utility> (for make_pair). (Dwarf_abbrev_table::do_read_abbrevs): Check for compressed debug sections. (Dwarf_ranges_table::read_ranges_table): Likewise. (Dwarf_pubnames_table::read_section): Check for GNU-style sections, and for compressed debug sections. (Dwarf_pubnames_table::read_header): Compute end address of table. (Dwarf_pubnames_table::next_name): Return flag_byte. Check for end of list by offset, not by offset == 0. (Dwarf_info_reader::do_read_string_table): Check for compressed debug sections. * gold/dwarf_reader.h (Dwarf_pubnames_table::Dwarf_pubnames_table): Initialize new data members. (Dwarf_pubnames_table::next_name): return flag_byte. (Dwarf_pubnames_table::end_of_table_): New data member. (Dwarf_pubnames_table::is_gnu_style_): New data member. * gold/gdb-index.cc (gdb_index_version): Update to version 7. (Gdb_index_info_reader::read_pubtable): Read flag_byte. (Gdb_index_info_reader::read_pubnames_and_pubtypes): Don't read skeleton type unit DIEs. (Gdb_index::add_symbol): Add flag_byte; adjust all callers. (Gdb_index::do_write): Write flag_byte. * gold/gdb-index.h (Gdb_index::add_symbol): Add flags parameter. (Gdb_index::Cu_vector): Store flags along with cu indexes. * gold/testsuite/gdb_index_test_3.sh: Allow versions 4-7. * gold/testsuite/gdb_index_test_comm.sh: Likewise.
