pow - Power

pow     dest, src0{ .x | .y | .z | .w}, src1{ .x | .y | .z | .w}

Name	Registers
dest	A temporary register.
src0	A temporary register, input register, or floating-point constant register.r. Must specify any one of { .x | .y | .z | .w } as the component.
src1	A temporary register, input register, or floating-point constant register.r. Must specify any one of { .x | .y | .z | .w } as the component.

Cannot specify the same register for src1 and dest.

Finds the src1 power of src0 and stores the result in dest.

tmp = src0{ .x | .y | .z | .w} ^ src1{ .x | .y | .z | .w}
dest.x = tmp
dest.y = tmp
dest.z = tmp
dest.w = tmp

log     dest.z, src0{ .x | .y | .z | .w}
mul     dest.z, dest.z, src1{ .x | .y | .z | .w}
exp     dest,   dest.z
