When building GDB with the following CFLAGS and CXXFLAGS as part of
configure line:
CFLAGS=-std=gnu11 CXXFLAGS=-std=gnu++11
Then run the selftest.exp, I see:
======
Running /home/lee/dev/binutils-gdb/gdb/testsuite/gdb.gdb/selftest.exp
...
FAIL: gdb.gdb/selftest.exp: run until breakpoint at captured_main
WARNING: Couldn't test self
=== gdb Summary ===
# of unexpected failures 1
/home/lee/dev/binutils-gdb/gdb/gdb version 13.0.50.20221206-git -nw -nx
-iex "set height 0" -iex "set width 0" -data-directory
/home/lee/dev/binutils-gdb/gdb/testsuite/../data-directory
======
It is the fact that when I use the previously mentioned CFLAGS and
CXXFLAGS as part of the configuration line, the default value (-O2 -g)
is overridden, then GDB has no debug information. When there's no debug
information, GDB should not run the testcase in selftest.exp.
The root cause of this FAIL is that the $gdb_file_cmd_debug_info didn't
get the right value ("nodebug") during the gdb_file_cmd procedure.
That's because in this commit,

Clean up "Reading symbols" output
It changed "no debugging..." to "No debugging..." which causes the above
problem. This patch only updates the corresponding pattern to fix this
issue.
With this patch applied, I see:

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.
