My concern is - a large fraction of our tests, not just those in this file. rely on the default std version (I suspect setting it to c++98 will reveal that). I don't think maintaining this information alongside each test and plumbing it through every test helper is reasonable. If we want to be robust to changes in this flag, I think need to make at least TestTU do the right thing by default. Unfortunately the most obvious way to do that (adding `-std-default`) won't work. - there's no buildbot coverage of these configurations, so I'm not sure how we'll keep them clean. Given there's no obvious alternative and the patch is small, it seems OK to land this (with a suitable comment), but it's hard for us to commit to maintaining it e.g. - if we add non-C++ testcases in SymbolCollectorTests and need to remove the arg - for other values of `CLANG_DEFAULT_STD_CXX` - as more tests are added in the future CHANGES SINCE LAST ACTION https://reviews.llvm.org/D60539/new/ https://reviews.llvm.org/D60539 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
