Summary: clang should warn if a class and its subclass have a
method with the same signature but no "virtual" in
base class
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: normal
Priority: P
Component: C++
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: nicolasweber at gmx.de
CC: llvmbugs at cs.uiuc.edu, dgregor at apple.com
Consider
class A {
public:
void f() {}
};
class B : public A {
public:
void f() {}
};
It is likely that B::m is supposed to be an override of A::m, but "virtual" is
missing. We should add this warning and check how noisy it is. If it's not
noisy, it should be added to the -Wall group.
