--- Comment #2 from mcccs at gmx dot com ---
Nor does the following use bfcvt:

void convert1(int a, int b, int c, int d, __bf16 *x) {
    x[0] = (__bf16)a;
    x[1] = (__bf16)b;
    x[2] = (__bf16)c;
    x[3] = (__bf16)d;
}

void convert1(float a, float b, float c, float d, __bf16 *x) {
    x[0] = (__bf16)a;
    x[1] = (__bf16)b;
    x[2] = (__bf16)c;
    x[3] = (__bf16)d;
}

This seems to be a bug?
