This isn't the QPU, for which Broadcom released docs a little while ago; it's the main processor, which is a VC4 core. It's a rather elegant thing with two cores, 32 registers, a built-in DSP and an extremely nice instruction set; reverse eng...

It all just goes into the accumulator, X index, or Y index based on the specific instruction. So, my question is, when I'm defining my ins, outs and registers for these instructions, is it going to be a problem that
