From 6f1e26aa560fef1cc1b97939fee83feabbf0d3aa Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Mon, 3 Apr 2023 03:47:46 +0200 Subject: [PATCH] [gdb/testsuite] Add make-check-all.sh Directory gdb/testsuite/boards contains a number of host/target boards, which run a test-case (or test-cases) in a different way. The benefits of using these boards are: - improving test coverage of gdb, - making the testsuite more robust, and - making sure the test-cases work for non-native and remote setups, if possible. Each board is slightly different, and developers need to learn how to use each one, what parameters to pass and how, and which ones can be used in combination with each other. This is a threshold to start using them. And then there quite a few, so I suppose typically only a few will be used by each developer. Add script gdb/testsuite/make-check-all.sh, that's intended to function as a drop-in replacement of make check, while excercising all host/target boards in gdb/testsuite/boards. An example of make-check-all.sh for one test-case is: ... $ ~/gdb/src/gdb/testsuite/make-check-all.sh gdb.base/advance.exp LOCAL: # of expected passes 8 TARGET BOARD: cc-with-gdb-index # of expected passes 8 ... HOST BOARD: local-remote-host-notty, TARGET BOARD: remote-stdio-gdbserver # of expected passes 8 HOST/TARGET BOARD: local-remote-host-native # of expected passes 8 ... Shell-checked and tested on x86_64-linux. --- gdb/testsuite/make-check-all.sh | 323 ++++++++++++++++++++++++++++++++ 1 file changed, 323 insertions(+) create mode 100755 gdb/testsuite/make-check-all.sh diff --git a/gdb/testsuite/make-check-all.sh b/gdb/testsuite/make-check-all.sh new file mode 100755 index 00000000000..d54f9aaae2c --- /dev/null +++ b/gdb/testsuite/make-check-all.sh @@ -0,0 +1,323 @@ +#!/bin/bash + +# Copyright (C) 2023 Free Software Foundation, Inc. +# This program is free software; you can redistribute it and/or modify +# it under the terms of the GNU General Public License as published by +# the Free Software Foundation; either version 3 of the License, or +# (at your option) any later version. +# +# This program is distributed in the hope that it will be useful, +# but WITHOUT ANY WARRANTY; without even the implied warranty of +# MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
