It has been tested mostly on x86-64, but it contains generic optimizations for all targets. It should bring even more improvements on RISC hosts, as it avoid long sequence of instructions for constant loading. > it seems that not many people are interested in sparc(64) emulation speed > or on vacation :) > or the emulation is just perfect in par with a real sun4u (i don't own one > so i can't test) The point is that emulation has a cost, and it's quite difficult to to lower it and thus improve the emulation speed. For what I have been able to see, the sparc (but also mips and sh4) targets would benefit from MMU emulation improvements. But that's not easy to do either.
