Bug ID: 45165
Summary: -Wdocumentation has false positives in template
members of variadic template classes
Product: clang
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected], [email protected],

Running the following code with -fsyntax-only -Wdocumentation:
template<typename... Args>
struct X {
/// @param args Arguments.
template<typename T>
static int f(T t, Args... args) { return 1; }
};
void call() {
X<>::f(1);
}
produces the warning
<source>:3:16: warning: parameter 'args' not found in the function declaration
[-Wdocumentation]
/// @param args Arguments.
^~~~
<source>:3:16: note: did you mean 't'?
/// @param args Arguments.
^~~~
t
That's likely because the template parameter pack is empty, so in X<> the
method doesn't take any "args".
