================ Comment at: test/Parser/switch-recovery.cpp:108 expected-error {{no member named 'x' in the global namespace; did you mean simply 'x'?}} \ - expected-warning 2 {{expression result unused}} + expected-warning {{expression result unused}} 9:: :y; // expected-error {{expected ';' after expression}} \ ---------------- rsmith wrote: > Hmm, why do we only get one warning here? I'd expect one warning for the `8;` > and one for the `x;` (after applying the fixes from the errors). We get the one for the `8;` but the other one is a `TypoExpr` and it claims it's type dependent, and we don't warn on type dependent so we bail out pretty early in `Expr::isUnusedResultAWarning()`. ================ Comment at: test/SemaCXX/for-range-examples.cpp:181 for (+x : {1, 2, 3}) {} // expected-error {{undeclared identifier}} expected-error {{expected ';'}} - for (+y : {1, 2, 3}) {} // expected-error {{must declare a variable}} + for (+y : {1, 2, 3}) {} // expected-error {{must declare a variable}} expected-warning {{expression result unused}} } ---------------- rsmith wrote: > The new warnings here aren't ideal; do you know why they show up? Because the first part in a for loop can be an expression, but only if it's not a range-based for loop. However, I was able to do some lookahead to retain the old behavior here.
