That is, make CHECK-DAG skip matches that overlap the matches of any preceding consecutive CHECK-DAG directives. This change makes CHECK-DAG more consistent with other directives, and there is evidence it makes CHECK-DAG more intuitive and less error-prone. See the RFC discussion starting at: http://lists.llvm.org/pipermail/llvm-dev/2018-May/123010.html Moreover, this behavior enables CHECK-DAG groups for unordered, non-unique strings or patterns. For example, it is useful for verifying output or logs from a parallel program, such as the OpenMP runtime. This patch also implements the command-line option -allow-deprecated-dag-overlap, which reverts CHECK-DAG to the old overlapping behavior. This option should not be used in new tests. It is meant only for the existing tests that are broken by this change and that need time to update. See the following bugzilla issue for tracking of such tests: https://bugs.llvm.org/show_bug.cgi?id=37532 Patches to add -allow-deprecated-dag-overlap to those tests will follow immediately.
