Hello, I've recently run into an unknown bit in Tesla shaders, and was hoping you could shed some light on it. I believe they're related to clamping of some sort. Here are 2 examples (from diff shaders): a0000401 cc054780 cvt rpi f32 $r0 f32 $r2 [unknown: 00000000 00010000] a000060d 8c014780 cvt rni s32 $r3 f32 $r3 [unknown: 00000000 00010000] [This is intel-style syntax, cvt = convert/move, rni/rpi = rounding mode stuff, hope that clears up the syntax...] The destination register tends to go to a texture-related instruction input, in some cases the layer (which is why I...
