binutils-gdb modified for the FreeChainXenon project
![]() When running test-case gdb.cp/cpexprs-debug-types.exp with target board cc-with-debug-names on a system with gcc 12.1.1 (defaulting to dwarf 5), I run into: ... (gdb) file cpexprs-debug-types^M Reading symbols from cpexprs-debug-types...^M warning: Section .debug_aranges in cpexprs-debug-types has duplicate \ debug_info_offset 0x0, ignoring .debug_aranges.^M gdb/dwarf2/read.h:309: internal-error: set_length: \ Assertion `m_length == length' failed.^M ... The exec contains a .debug_names section, which gdb rejects due to .debug_names containing a list of TUs, while the exec doesn't contain a .debug_types section (which is what you'd expect for dwarf 4). Gdb then falls back onto the cooked index, which calls create_all_comp_units to create all_comp_units. However, the failed index reading left some elements in all_comp_units, so we end up with duplicates in all_comp_units, which causes the misleading complaint and the assert. Fix this by: - asserting at the start of create_all_comp_units that all_comp_units is empty, as we do in create_cus_from_index and create_cus_from_debug_names, and - cleaning up all_comp_units when failing in dwarf2_read_debug_names. Add a similar cleanup in dwarf2_read_gdb_index. Tested on x86_64-linux. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=29381 |

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.
