[PATCH] D52690: [clang-tidy] NFC use CHECK-NOTES in tests for misc-misplaced-const

[Jonas Toth via Phabricator via cfe-commits]

JonasToth added inline comments.


================
Comment at: test/clang-tidy/misc-misplaced-const.c:18
+  // CHECK-NOTES: :[[@LINE-1]]:12: warning: 'i3' declared with a const-qualified typedef type; results in the type being 'int *const' instead of 'const int *'
+  // CHECK-NOTES: :[[@LINE-14]]:14: note: typedef declared here

Another useful feature is that tests should be easy to create, read, and change.  In cases like this - where the benefit of the change is not obvious - I would leave the decision to the author of the check.
