<div>
<pre>In the following code clang will complain about deprecated enumerator:
// clang++ -std=c++11 input.cpp
enum X {
a = 1,
b [[deprecated]] = 2,
};
int foo(X x) {
switch(x) {
case a:
return 10;
case b: // complains that 'b' is deprecated
return 15;
}
return 20;
}
However, removing 'case b' will cause clang to complain about enumeration value
unhandled in the switch.
Maybe we should consider silencing the deprecation warnings in that case?</pre>
