<pre>bool g();
enum r { no , yes};
r test(r res) {
res = (res == no) ? yes : res = no;
bool t = t = g();
return res ;
}
This should warn. GCC catches it, Clang not.
-std=c++17
int r(int a) {
return a++ << a++;
}
This one is defined with C++17. Expression E1 is sequenced before the
expression E2, but Clang produces incorrect warnings.</pre>
