            Bug ID: 45161
           Summary: Please add a warning for potentially throwing code in
                    noexcept function
           Product: clang
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
          Assignee: unassignedclangbugs at nondot.org
          Reporter: rafael at espindo.la

Clang warns for

void foo() noexcept {
    throw 42;
}

But even -Weverything will not produce a warning for

static void bar() {
    throw 42;
}
void foo() noexcept {
    bar();
}

It would be quite convenient to have such a warning to help make a codebase
"noexcept correct". Having an extra warning for "could have been marked
noexcept" would also be useful.
