Arria DSP block merge with fixed point in OpenCL

Hello, I have been trying to implement fixed point algorithms using opencl for an arria10. I am interested in this approach because I run out of DSP blocks when I used floating point so I fig...

And for completeness, I simply took the vector add example and changed it to a multiply while changing data types from floats to ints. Then I masked the bits according to the programming guide. This used a single DSP block as expected. When I changed to int2, this still used a single dsp block which is what led me to believe it worked. Previously with 16.1, this would have used 2 dsp blocks. I will do some more investigating as I ran out of time today.
