This adds a new "-dwarf-5" switch to "save gdb-index" that makes it generate index files with DWARF-5 .debug_names/.debug_str sections instead of GDB's own .gdb_index. We should probably add a command line option to contrib/gdb-add-index.sh (incl. cc-with-tweaks.sh) for the new -dwarf-5 GDB option, and a new target board to make it more convenient to exercise this. To be done later. gdb/ChangeLog 2017-12-08 Jan Kratochvil <jan.kratochvil@redhat.com> Pedro Alves <palves@redhat.com> * contrib/gdb-add-index.sh (index): Rename to ... (index4): ... here. (index5, debugstr, debugstrmerge, debugstrerr): New variables. Support also .debug_names and .debug_str. * dwarf2read.c: Include cmath, set, list. (INDEX_SUFFIX): Rename to ... (INDEX4_SUFFIX): ... here. (INDEX5_SUFFIX, DEBUG_STR_SUFFIX): New. (file_write(FILE *, const void *, size_t)): New. (file_write(FILE *, const std::vector<Elem, Alloc> &)): New. (data_buf::append_unsigned_leb128, data_buf::empty): New. (data_buf::file_write): Use ::file_write. (data_buf::c_str, dwarf5_djb_hash, debug_names) (check_dwarf64_offsets): New. (psyms_seen_size, write_gdbindex): New from write_psymtabs_to_index code. (dwarf5_gdb_augmentation, write_debug_names, assert_file_size) (enum dw_index_kind): New. (write_psymtabs_to_index): New parameter index_kind. Support filename_str and out_file_str. Move code to write_gdbindex, possibly call write_debug_names. (save_gdb_index_command): New parameter -dwarf-5. (_initialize_dwarf2_read): Document the new parameter -dwarf-5. gdb/doc/ChangeLog 2017-12-08 Jan Kratochvil <jan.kratochvil@redhat.com> * gdb.texinfo (Index Files): Document .debug_names and -dwarf-5. -- gdb/contrib/gdb-add-index.sh | 53 ++ gdb/doc/gdb.texinfo | 24 + gdb/dwarf2read.c | 919 ++++++++++++++++++++++++++++++++++++++++-- 3 files changed, 935 insertions(+), 61 deletions(-) |

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.
