Bug #: 53711
Summary: Wunused-function should warn for functions in the
unnamed namespace
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: enhancement
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
Wunused-function currently only warns for functions that are declared as static
that are never used / defined. It should also warn about functions placed in
the unnamed namespace, such as:
namespace {
void f();
}
Such functions have similar mechanics to static functions. In particular, they
can only be referenced in the translation unit, so the compiler knows for
certain that if the function is not used in this translation unit, it is not
used.
