Subject: [PATCH] gdb/testsuite: XFAIL some gdb.base/fileio.exp
Date: Fri, 11 Aug 2023 12:21:34 +0200 [thread overview]
Message-ID: <20230811102134.2796842-1-blarsen@redhat.com> (raw)
Some gdb.base/fileio.exp tests expect the inferior to not have write
access to some files. If the test is being run as root, this is never
possible. This commit adds a way to identify if the user is root and
xfails the tests that expect no write access.
