Hi, namespace has nothing to do with the issue,
The problem can be summarized as follows:
if you have a declaration of the template function without always_inline and
the definition with, the instationation does not get always_inline.
Take this testcase:
template <class T>
const T& min(const T& a, const T& b);
template <class T>
inline __attribute__ ((always_inline)) const T&
min(const T& a, const T& b)
{
return a < b ? a : b;
}
int main()
{
int a, b;
return min(a, b);
}
We don't inline min into main if we remove the declaration, we do.
