Replaced with RecursiveASTVisitor. ================ Comment at: clang-tools-extra/test/clang-tidy/checkers/performance/unnecessary-copy-on-last-use.cpp:1 +// RUN: %check_clang_tidy %s -std=c++17 performance-unnecessary-copy-on-last-use %t +// RUN: %check_clang_tidy %s -std=c++11 performance-unnecessary-copy-on-last-use %t ---------------- njames93 wrote: > Running this check explicitly in c++11/17 implies you expect different > diagnostics, if so you can use the `--check-suffixes` flag to enable checking > configurations. Search for other tests which use that if you're unsure Not necessarily, I just want the check to work with c++11 and after the changes to the language after c++17 (e.g. guaranteed copy elision).
