Bug #: 13890
Summary: Final abstract classes should generate warnings
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++11
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
class Animal {
virtual void print() const = 0;
};
class Dog final : public Animal {
};
In this code, i would expect a compiler warning as Dog is final, but is still
abstract as it didn't implement a print method. Its also possible to put final
on Animal itself which doesn't really make sense as then Animal is an abstract
class which cannot be implemented by anyone.
-Wall doesn't show anything for this test. -Weverything does, but the messages
aren't related to this:
cpp11.cpp:1:7: warning: 'Animal' has virtual functions but non-virtual
destructor [-Wnon-virtual-dtor]
class Animal {
^
cpp11.cpp:4:11: warning: 'final' keyword is incompatible with C++98
[-Wc++98-compat]
class Dog final : public Animal {
^
cpp11.cpp:4:7: warning: 'Dog' has virtual functions but non-virtual destructor
[-Wnon-virtual-dtor]
class Dog final : public Animal {
