Looks like Sema uses "null" not only when referring to literals (see below).
Also, if we were referring to literals, we would use single quotes, no?
I suggest keeping as is for consistency with the wording that uses nil. I do
not see much difference between the two cases..
TestObject * _Nonnull returnsNilObjCInstanceDirectly() {
// The first warning is from Sema. The second is from the static analyzer.
return nil; // expected-warning {{null returned from function that
requires a non-null return value}}
// expected-warning@-1 {{nil returned from a function that is
expected to return a non-null value}}
}
