Summary: Annoying -Wunused-function
Product: clang
Version: trunk
Platform: PC
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
The following code:
namespace {
template<class T>
inline void char_less(T t1, T t2)
{ }
template<>
inline void char_less<char>(char t1, char t2)
{ }
}
Is triggered by -Wunused-function :
warning: unused function 'char_less' [-Wunused-function]
inline void char_less<char>(char t1, char t2)
Putting functions in unnamed namespaces is a common trick. While
-Wunused-function is not triggered by the templated function, it is triggered
by the specialization.
