Mark the next instruction as having a label index.

|---|
where # identifies the label number.
For vs_2_0, and vs_2_x, the label number must be between between 0 and 15.
For vs_2_sw, vs_3_0 and vs_3_sw, the label number must be between between 0 and 2047.
| Vertex shader versions | 1_1 | 2_0 | 2_x | 2_sw | 3_0 | 3_sw |
|---|---|---|---|---|---|---|
| label | x | x | x | x | x |
This instruction defines a label located at the next shader instruction. The label instruction can only be present directly after a ret instruction (which defines the end of the previous subroutine or main program).
