call (Pixel Shader)

Performs a function call to the instruction marked with the provided label index.

Syntax

Where:

• label is a label number.

Remarks

This instruction does the following:

1. Push address of the next instruction to the return address stack.
2. Continue execution from the instruction marked by the label.

Only forward calls are allowed. This means that the location of the label inside the pixel shader should be after the call instruction referencing it.

Nested calls are not allowed for ps_2_x or ps_2_sw.

Nested calls are allowed for ps_3_0 and ps_3_sw.
