cjdb added a comment.
I think this is a good diagnostic to add: it improves readability and eliminates ambiguities. My only request is that if there isn't already a FixIt hint, one be added, please.
================
Comment at: clang/test/Sema/parentheses.c:94
(void)(x + y > 0 ? 1 : 2); // no warning
(void)(x + (y > 0) ? 1 : 2); // expected-warning {{operator '?:' has lower precedence than '+'}} expected-note 2{{place parentheses}}
----------------
I think this should also warn.
