Subject: [PATCH] gdb/testsuite: fix gdb.threads/linux-dp.exp regex
Date: Fri, 7 Oct 2022 15:21:04 +0100 [thread overview]
Message-ID: <20221007142104.261240-1-lancelot.six@amd.com> (raw)
On ubuntu 22.04 with debug the libc6-dbg package installed, I have the
following failure:
where
#0 print_philosopher (n=3, left=33 '!', right=33 '!') at .../gdb/testsuite/gdb.threads/linux-dp.c:105
#1 0x000055555555576a in philosopher (data=0x55555555937c) at .../gdb/testsuite/gdb.threads/linux-dp.c:148
#2 0x00007ffff7e11b43 in start_thread (arg=<optimized out>) at ./nptl/pthread_create.c:442
#3 0x00007ffff7ea3a00 in clone3 () at ../sysdeps/unix/sysv/linux/x86_64/clone3.S:81
(gdb) FAIL: gdb.threads/linux-dp.exp: first thread-specific breakpoint hit
The regex for this test accounts for different situations (with /
without debug symbol) but assumes that if debug info is present the
backtrace shows execution under pthread_create. However, for the
implementation under test, we are under start_thread.
Update the regex to accept start_thread.
Tested on Ubuntu-22.04 x86_64 with and without libc6-dbg debug symbols
available.
