Changes in DejaGnu 1.6.2 mean that our testsuite will no longer run. This is because of some confusion over how the gdb.exp file is handled. The gdb.exp file is really the tool init file, which is loaded from within the DejaGnu core, and it should not be loaded directly from any other file in the testsuite. DejaGnu tries to prevent the same library being loaded twice by remembering the names of library files as they are loaded. Until recently loading the tool init file in DejaGnu was very similar to loading a library file, as a result, loading the gdb.exp tool init file simply recorded 'gdb.exp' as having been loaded, future attempts to load 'gdb.exp' as a library would then be ignored (as the file was marked as already loaded). DejaGnu has now changed so that it supports having both a tool init file and a library with the same name, something that was not possible before. What this means however is that when the core loads the 'gdb.exp' tool init file it no longer marks the library 'gdb.exp' as having been loaded. When we then execute 'load_lib gdb.exp' we then try to reload the 'gdb.exp' file. Unfortunately our gdb.exp file can only be loaded once. It use of 'rename cd builtin_cd' means that a second attempt to load this file will fail. This was discussed on the DejaGnu list here: http://lists.gnu.org/archive/html/dejagnu/2019-03/msg00000.html and the suggested advice is that, unless we have some real requirement to load the tool init file twice, we should remove calls to 'load_lib gdb.exp' and rely on DejaGnu to load the file for us, which is what this patch does. I've tested with native X86-64/GNU Linux and see no regressions. gdb/testsuite/ChangeLog: * config/default.exp: Remove 'load_lib gdb.exp'. * config/monitor.exp: Likewise. * config/sid.exp: Likewise. * config/sim.exp: Likewise. * config/slite.exp: Likewise. * config/unix.exp: Likewise. * gdb.base/default.exp: Remove unhelpful comment.

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.
