continuec (sm4 - asm)

  • Article

Conditionally continues execution at the beginning of the current loop.

continuec{_z|_nz} src0.select_component
Term Description
src0
 [in] The component against which to test the condition.

Remarks

continuec can be used only inside a loop or endloop.

The following example shows how to use the continuec instruction.

                loop
                    if_na r0.x
                        break
                    endif
                    continuec_z r1.x  // if all bits of r1.x are zero then
                                      // continue at beginning of loop.
                    ...
                    continuec_nz r3.y // if any bit in r3.y is set then
                                      // continue at beginning of loop.

                    ...
                endloop

The token format contains the offset of the corresponding loop instruction in the Shader as a convenience.
