Author: mgorny Date: Mon Jun 17 02:49:05 2019 New Revision: 363536 URL: http://llvm.org/viewvc/llvm-project?rev=363536&view=rev Log: [lldb] [test] Skip watchpoint tests on NetBSD if userdbregs is disabled
Skip watchpoint tests if security.models.extensions.user_set_dbregs is disabled. This indicates that unprivileged processes are not allowed to write to debug registers which is a prerequisite for using hardware watchpoints.
