In commit 6423214f (testsuite: Don't use expect_background to reap gdbserver), we override gdb_exit in lib/gdbserver-support.exp, so that we can close gdbserver first. However, we don't close gdbserver in mi_gdb_exit. This makes a problem in my aarch64 mulit-arch testing, in which I run some mi tests, mi-watch.exp for example, in different variations (aarch64 and arm), Schedule of variations: junor0-2 junor0-2-arm/-marm junor0-2-arm/-mthumb When the test is done in the first variation (aarch64), test case is recompiled for arm, but GDBserver with aarch64 program is still running. When the second variation is started, GDB loads arm program, but GDBserver still loads aarch64 program because the old GDBserver process is using it. We'll get, 47-target-select remote junor0-2:2350^M &"warning: Selected architecture arm is not compatible with reported target architecture aarch64\n"^M &"warning: Architecture rejected target-supplied description\n" This patch fixes this problem by closing GDBserver in mi_gdb_exit. gdb/testsuite: 2016-09-22 Yao Qi <yao.qi@linaro.org> * lib/gdbserver-support.exp: Rename mi_gdb_exit. (gdb_exit): Rename it to ... (gdbserver_gdb_exit): ... Close GDBserver. (gdb_exit): New proc, call gdbserver_gdb_exit. (mi_gdb_exit): Likewise.

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.
