I figured as much; my question was more along the lines of, if the OpenCL compiler (I use the one from the Windows Catalyst 11.7 drivers) complains about it being unused, will it still "behave a certain way" then, or will t1 just be removed and the desired behaviour doesn't happen.

Whatever, just answers this if you feel like it, I don't want to steal more of your time. Thanks again for such a great miner.
