First of all sorry for my inactivity, I will finally have time from now. Lukas, thanks for all the resources you posted, I will go through all of them, they seem really helpful. I looked at the generated binary on bull and found the op codes from the isa file. My idea is that I could set up a very basic sample kernel and generate a binary for it. (I guess I would copy the code from "opencl_build_kernel_save" (common-opencl.c) to do this.) Then I could check the isa and make a very little change in the binary based on it. If this works, I could work out a way that would allow us to change arbitrary isa code in the binary. To achieve this I would have to understand the whole structure of the binary and the way it is loaded. Do you think my approach is doable, or am I missing something important?
