Subject: [PATCH 3/3] gdb: testsuite: enhance gdb_attach to fix jit-elf.exp
Date: Wed, 16 Mar 2022 17:58:29 +0800 [thread overview]
Message-ID: <1647424709-23680-4-git-send-email-yangtiezhu@loongson.cn> (raw)
In-Reply-To: <1647424709-23680-1-git-send-email-yangtiezhu@loongson.cn>
If /proc/sys/kernel/yama/ptrace_scope is 1, when execute the following
command without superuser:
make check-gdb TESTS="gdb.base/jit-elf.exp"
we can see the following messages in gdb/testsuite/gdb.log:
(gdb) attach 1650108
Attaching to program: /home/yangtiezhu/build/gdb/testsuite/outputs/gdb.base/jit-elf/jit-elf-main, process 1650108
ptrace: Operation not permitted.
(gdb) FAIL: gdb.base/jit-elf.exp: attach: one_jit_test-2: break here 1: attach
handle the above case in gdb_attach, and then use gdb_attach to fix
the above issue.
