Compiling code below (g++ -O5 -c) fails with the error message below.
This is the major source of performance loss since it leaves silly functions
like this called zillions of times w/out inlining.

Any workaround ?

Yuri

---- code ----
template<typename T> __attribute__ ((__always_inline__)) T f(const T j) { return
(j); }

int x(int j) {
  int r;
  r = f(j);
  return (r);
}

---- error message ----
i.C:2: sorry, unimplemented: inlining failed in call to 'T f(T) [with T = int]':
function not inlinable
i.C:6: sorry, unimplemented: called from here

actually this one is fixed in 4.0, problem though is that 4.0 isn't usable yet
