  • Artykuł

Moves the point of execution to the instruction after the next endloop or endswitch.

break

 

Remarks

The token format contains the offset of the corresponding endloop or endswitch instruction in the Shader as a convenience.

The following example shows the break instruction.

                loop
                    // example of termination condition
                    if_nz r0.x
                        break
                    endif
                    ...
                endloop

This instruction must appear within a loop/endloop or in a case in a switch/endswitch.

This instruction applies to the following shader stages:

Vertex Shader Geometry Shader Pixel Shader
