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).

Summary: Missed changing of sin into sinf (likewise for cos to
cosf)
