Commen= t # 1 on bug 10586= 9 from Jan Vesely 
What is the clang/llvm version? I cannot reproduce using clang=
-5.0.1:
$ cat foo.cl=20
#pragma OPENCL EXTENSION cl_khr_fp64: enable

kernel void PulseWave(global float* buffer, size_t num_harmonics,
        float duty_cycle)
{
        size_t index =3D get_global_id(0);
        float phase =3D buffer[index];
        float sample =3D duty_cycle;
        float precompute1 =3D (phase - duty_cycle / 2.0) * 2.0 * M_PI;
        for (size_t i =3D 1; i <=3D num_harmonics; ++i)
        {
                float harmonic =3D 2.0 / (i * M_PI) * sin(M_PI * i * duty_c=
ycle)
*
                        cos(i * precompute1);
                sample +=3D harmonic;
        }
        buffer[index] =3D sample * 2.0 - 1.0;
}
