Description Andrew Pinski 2007-07-09 03:25:59 UTC 
Testcase:
float _Complex quantum_cexp(float phi)
{
  return __builtin_cos(phi) + 1i * __builtin_sin(phi);
}

--- CUT ----
We should able to change cos/sin here into cosf/sinf (and then into cexpfi).
This shows up in libquantum (which is part of SPEC 2k6 but the sources I am using to test are the open soruce ones and not the SPEC 2k6 ones).
Comment 1 Richard Biener 2007-07-09 09:36:31 UTC 
Confirmed.
Comment 2 Andrew Pinski 2014-12-01 05:12:23 UTC 
This testcase has been fixed so closing as such.
