+    FLOAT a[90], b[90], got;
+    CONST FLOAT expected[] =
+    { 0.0f, 0.0f, 17.0f, 222.0f, 1300.0f, 5050.0f, 15225.0f,

+    {
+        a[i] = (FLOAT)i;
+        b[i] = (FLOAT)i + 0.5f;
+    }
+
+/* D3DXSHDot computes by using order * order elements */
+    for (i = 0; i < 9; i++)
+    {
+        got = D3DXSHDot(i, a, b);
+        ok(relative_error(got, expected[i]) < admitted_error, "order
%d: expected %f, received %f\n", i, expected[i], got);
+    }
+
+    return;
+}

Making the "a" and "b" arrays 90 elements big doesn't make much sense.
If your D3DXSHDot implementation is correct, for the i = 8 case you
only need 8 * 8 = 64 elements. Also notice that the "expected" array
has 10 elements, while you use only 9.

Also please recheck formatting and whitespaces of this patch and patch 2/2.
