Hi! Amazing work! I see some 50 % speed ups in FlightGear and even more. While normally 3D clouds tear performance down to an unflyable stutter, with your branch I can fly in densly clouded conditions at usable framerates. I can now turn all shaders to maximum and enjoy the view. This makes a huge difference.
Unfortunately there's a downside as well: [ 4644.872676] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec [ 4644.872681] radeon 0000:01:00.0: GPU lockup (waiting for 0x00000000000a0c1d last fence id 0x00000000000a0c16) [ 4644.873727] radeon 0000:01:00.0: Saved 215 dwords of commands on ring 0.

Is there someting I can do to debug this? Or are problems like this already expected? In any case please keep up this work! Even though it might eventually be replaced by some llvm backend, this could make your users very happy in the mean time.
