I couldn't easily find a way to get it to generate the pow instruction, no.

Test pow.shader_test doesn't pass on my machine, on both video cards. On the NVIDIA card I need at least 3 ULPs of allowance to have it pass, on the Intel card 2 ULPs are enough. I would suggest to allow 3 ULPs, to avoid spurious errors. On another computer with an AMD video card the test runs just fine. Giovanni.
