When building with gcc with -gdwarf-5 ld tests (including ld-elf/dwarf.exp) fail because they try to read the .debug_ranges section. But DWARF5 introduces a new .debug_rnglists section that encodes the address ranges more efficiently. Implement reading the debug_rnglists in bfd/dwarf2.c. Which makes all tests pass again and fixes several gcc testsuite tests when defaulting to DWARF5. * dwarf2.c (struct dwarf2_debug_file): Add dwarf_rnglists_buffer and dwarf_rnglists_size fields. (dwarf_debug_sections): Add debug_rnglists. (dwarf_debug_section_enum): Likewise. (read_debug_rnglists): New function. (read_rangelist): New function to call either read_ranges or read_rnglists. Rename original function to... (read_ranges): ...this. (read_rnglists): New function.

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.
