From 108e60844c6c517895011f46b74db6b10273be56 Mon Sep 17 00:00:00 2001 From: Tom de Vries Date: Thu, 23 Sep 2021 22:42:10 +0200 Subject: [PATCH] [gdb/testsuite] Handle failing probe detection in gdb.base/break-probes.exp When running test-case gdb.base/break-probes.exp on ubuntu 18.04.5, we have: ... (gdb) bt^M #0 0x00007ffff7dd6e12 in ?? () from /lib64/ld-linux-x86-64.so.2^M #1 0x00007ffff7dedf50 in ?? () from /lib64/ld-linux-x86-64.so.2^M #2 0x00007ffff7dd5128 in ??

()^M (gdb) FAIL: gdb.base/break-probes.exp: ensure using probes ... The test-case intends to emit an UNTESTED in this case, but fails to do so because it tries to do it in a regexp clause in a gdb_test_multiple, which doesn't trigger. Instead, a default clause triggers which produces the FAIL. Also the use of UNTESTED is not appropriate, and we should use UNSUPPORTED instead. Fix this by silencing the FAIL, and emitting an UNSUPPORTED after the gdb_test_multiple: ... if { ! $using_probes } { + unsupported "probes not present on this system" return -1 } ...
