Uros, would you mind adding the testcase as well? I know it's small, but 
who knows what it's good for -- we got this case wrong once already, let's 
make sure we don't again. 
 
Thanks 
  Wolfgang

(In reply to comment #7)

No problem, this one should do the trick:

--cut here--
/* PR target/19236 */
/* { dg-do compile { target i?86-*-* } } */
/* { dg-options -ffast-math } */

extern float log1pf (float);
extern double log1p (double);  

float testf (float __x) { 
  return log1pf(1.0); 
}

double test (double __x) { 
  return log1p(1.0); 
}
--cut here--
