These tests exercise the infrun.c:proceed code that needs to know to start new step overs (along with switch_back_to_stepped_thread, etc.). That code is tricky to get right in the multitude of possible combinations (at least): (native | remote) X (all-stop | all-stop-but-target-always-in-non-stop) X (displaced-stepping | in-line step-over). The first two above are properties of the target, but the different step-over-breakpoint methods should work with any target that supports them. This patch makes sure we always test both methods on all targets. Tested on x86-64 Fedora 20. gdb/testsuite/ChangeLog: 2015-04-10 Pedro Alves <palves@redhat.com> * gdb.threads/step-over-lands-on-breakpoint.exp (do_test): New procedure, factored out from ... (top level): ... here. Add "set displaced-stepping" testing axis. * gdb.threads/step-over-trips-on-watchpoint.exp (do_test): New parameter "displaced". Use it. (top level): Use foreach and add "set displaced-stepping" testing axis.
