Bug ID: 15240
Summary: duplicate warning about deprecated destructor
Product: clang
Version: trunk
Hardware: PC
OS: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
This code:
struct B {
~B() __attribute__((deprecated));
};
struct X : public B { };
void test() {
X *x = new X;
delete x;
}
produces:
$ clang y.cc
y.cc:5:8: warning: '~B' is deprecated [-Wdeprecated-declarations]
struct X : public B { };
^
y.cc:2:3: note: '~B' declared here
~B() __attribute__((deprecated));
^
y.cc:5:8: warning: '~B' is deprecated [-Wdeprecated-declarations]
struct X : public B { };
^
y.cc:2:3: note: '~B' declared here
~B() __attribute__((deprecated));
^
2 warnings generated.
The issue is that the diagnostic is emitted from
MarkBaseAndMemberDestructorsReferenced, which is called twice, once from
SetCtorInitializers and once from DefineImplicitDestructor.
