I can imagine how conflicting summary names in unittests binary would cause pain. Having an exaggeratedly unique name which would inspire other test authors to follow seems good enough for now. We can enforce uniqueness later if this becomes a problem. https://github.com/llvm/llvm-project/pull/180021 _______________________________________________ cfe-commits mailing list [email protected] https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
