yes, does look like a new cat4 instruction.. I guess if you have a simple shader that triggers the instruction, and the rest of the disassembled shader, it shouldn't be too hard to figure out what it is.

The result I tried.
OPC_RSQH = _OPC(4, 9),
OPC_LOG2H = _OPC(4, 10),
OPC_EXP2H = _OPC(4, 11),
but I don't know what is sinpb2?
from freedreno.
rsqh/log2h/exp2h... wonder if those are for half-precision (mediump)? What happens if you try to use highp?
sinpb2, not really sure.. I'd have to see how it is used (ie. asm dump vs glsl)
