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.
README for GNU development tools This directory contains various GNU compilers, assemblers, linkers, debuggers, etc., plus their support routines, definitions, and documentation. If you are receiving this as part of a GDB release, see the file gdb/README. If with a binutils release, see binutils/README; if with a libg++ release, see libg++/README, etc. That'll give you info about this package -- supported targets, how to use it, how to report bugs, etc. It is now possible to automatically configure and build a variety of tools with one command. To build all of the tools contained herein, run the ``configure'' script here, e.g.: ./configure make To install them (by default in /usr/local/bin, /usr/local/lib, etc), then do: make install (If the configure script can't determine your type of computer, give it the name as an argument, for instance ``./configure sun4''. You can use the script ``config.sub'' to test whether a name is recognized; if it is, config.sub translates it to a triplet specifying CPU, vendor, and OS.) If you have more than one compiler on your system, it is often best to explicitly set CC in the environment before running configure, and to also set CC when running make. For example (assuming sh/bash/ksh): CC=gcc ./configure make A similar example using csh: setenv CC gcc ./configure make Much of the code and documentation enclosed is copyright by the Free Software Foundation, Inc. See the file COPYING or COPYING.LIB in the various directories, for a description of the GNU General Public License terms under which you can copy the files. REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info on where and how to report problems.
