<div>
<pre>When the following test case is compiled with clang, the noinline attribute on
the "m" definition is silently ignored during the code generation for
Test<int>::m.
If one moves the definition of f below Test<T>::m or instantiates Test in f
with a different type than int, the noinline attribute on Test<int>::m is
properly honoured.
noinline is just an example, of course. The same thing happens e.g. with the
no_sanitize_address attribute.
GCC also seems to have this issue.
template <typename T>
struct Test {
void m();
};
void f() {
Test<int> t;
}
void e();
template <typename T>
__attribute__((noinline))
void Test<T>::m() {
e();
}
void test(Test<int> t) {
t.m();
}</pre>
