crs - Cross product

crs     dest{ .x | .y | .z | .xy | .xz | .yz | .xyz }, src0, src1

Name	Registers
dest	A temporary register. Requires any one of { .x | .y | .z | .xy | .xz | .yz | .xyz } as the mask.
src0	A temporary register, an input register, or a floating-point constant register. Swizzling not possible. Cannot specify anything other than the default mask { .xyzw }.
src1	A temporary register, an input register, or a floating-point constant register. Swizzling not possible. Cannot specify anything other than the default mask { .xyzw }.

Cannot specify the same register for src0 and dest.
Cannot specify the same register for src1 and dest.
You cannot specify a floating-point constant register for both src0 and src1.
You cannot specify input registers using different indices for src0 and src1 at the same time.

Stores the cross product of three components of src0 and src1 in dest.

dest.x = src0.y * src1.z - src0.z * src1.y
dest.y = src0.z * src1.x - src0.x * src1.z
dest.z = src0.x * src1.y - src0.y * src1.x
