endrep (Vertex Shader)

End of a repeat block.

Syntax

Remarks

Vertex shader versions	1_1	2_0	2_x	2_sw	3_0	3_sw
endrep		x	x	x	x	x

• rep uses integer registers (i#).
• endrep must follow the last instruction of a repeat block.
• The endrep offset must be greater than the rep instruction offset.
• Repeat loops cannot be nested.
• Repeat loops are allowed to be either completely inside an if block or completely surrounding it, no straddling is allowed.
• rep consumes one vertex shader instruction slot but must be used with endrep, which consumes another.
• The maximum loop iteration count is 255.

This instruction works as shown here.

LoopInterationCount = LoopIterationCount - 1;
if (LoopIterationCount > 0)
    Continue execution at the StartLoopOffset
