Have you run this on any open source software to see how many results/violations show up? If yes, sharing the results will be useful. If not, then its a good exercise to run it on an open source software. You can even try running it on llvm itself.<div>

Hi Clang,<br>
<br>
The attached patch adds a C++ Checker to clang, it checks whether<br>
there are mistakes in override.<br>
<br>
The mistake mean things like this:<br>
<br>
class base {<br>
virtual void foo() const {/*...*/}<br>
};<br>
<br>
class child: public base {<br>
/* child::foo is probably meant to override base::foo but type<br>
signatures don't match<br>
perfectly */<br>
void foo() {}<br>
};<br>
<br>
and this:<br>
<br>
class base {<br>
void foo() const {}<br>
};<br>
<br>
class child: public base {<br>
/* child::foo is probably meant to override base::foo but<br>
that function is not virtual. */<br>
void foo() const {}<br>
};<br>
<br>
I implement this as a static analysis checker, because i think it's<br>
not too visible and not too fast.<br>
<br>
I will appreciate it if there are any advice about this patch.<br>
