[PATCH] D27248: [clang-tidy] Do not trigger unnecessary-value-param check on methods marked as final

[Felix Berger via Phabricator via cfe-commits]

flx added inline comments.


================
Comment at: test/clang-tidy/performance-unnecessary-value-param.cpp:276
+// Virtual method overrides of dependent types cannot be recognized unless they
+// are marked as override or final. Test that check is not triggered on methods
+// marked with override or final.

I filed https://llvm.org/bugs/show_bug.cgi?id=31236 to keep track of fixing the check for this case as well.
