The DWARF v5 Spec describes a (slightly) new format for V5 .dwp files. This patch updates GDB to allow it to read/process .dwp files in the new DWARF v5 format, while continuing to be able to read/process .dwp files in the older V1 & V2 formats (older, pre-standard formats). The two major differences between the V2 and the V5 format are: - The inclusion of DWARF-v5-specific sections: .debug_loclists.dwo .debug_rnglists.dwo - The .dwp section identifier encodings have changed. The table below shows the old & new encodings. Notice the re-purposing of 5, 7 & 8 in particular. Val DW4 section DW4 section id DW5 section DW5 section id --- ----------------- -------------- ----------------- -------------- 1 .debug_info.dwo DW_SECT_INFO .debug_info.dwo DW_SECT_INFO 2 .debug_types.dwo DW_SECT_TYPES -- reserved 3 .debug_abbrev.dwo DW_SECT_ABBREV .debug_abbrev.dwo DW_SECT_ABBREV 4 .debug_line.dwo DW_SECT_LINE .debug_line.dwo DW_SECT_LINE 5 .debug_loc.dwo DW_SECT_LOC .debug_loclists.dwo DW_SECT_LOCLISTS 6 .debug_str_offsets.dwo .debug_str_offsets.dwo DW_SECT_STR_OFFSETS DW_SECT_STR_OFFSETS 7 .debug_macinfo.dwo DW_SECT_MACINFO .debug_macro.dwo DW_SECT_MACRO 8 .debug_macro.dwo DW_SECT_MACRO .debug_rnglists.dwo DW_SECT_RNGLISTS |

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.
