Set `performance-move-const-arg.CheckTriviallyCopyableMove` option to `false` because "trivially copyable" is too strict and give warning for e.g. `MixData` class: https://github.com/llvm/llvm-project/blob/1fbfa333f64bf714efa84db6b1075fc864d53bf8/clang-tools-extra/clang-tidy/bugprone/EasilySwappableParametersCheck.cpp#L389 Here: https://github.com/llvm/llvm-project/blob/1fbfa333f64bf714efa84db6b1075fc864d53bf8/clang-tools-extra/clang-tidy/bugprone/EasilySwappableParametersCheck.cpp#L504-L505 I find `std::move` here useful, WDYT? With option set to `true` (default) we get these more warnings which are only about trivially copyable types: ```diff diff --git a/clang-tools-extra/clang-tidy/bugprone/EasilySwappableParametersCheck.cpp b/clang-tools-extra/clang-tidy/bugprone/EasilySwappableParametersCheck.cpp index a179d4bf66b4..5217dd4a50b6 100644 --- a/clang-tools-extra/clang-tidy/bugprone/EasilySwappableParametersCheck.cpp +++ b/clang-tools-extra/clang-tidy/bugprone/EasilySwappableParametersCheck.cpp @@ -502,7 +502,7 @@ struct Mix { MixData Data;
