Detailed Description

A value that is used outside the VPlan.

The operand of the user needs to be added to the associated LCSSA phi node.

◆ fixPhi()

void VPLiveOut::fixPhi	(	VPlan &	Plan,
		VPTransformState &	State
	)

Fixup the wrapped LCSSA phi node in the unique exit block.

This simply means we need to add the appropriate incoming value from the middle block as exiting edges from the scalar epilogue loop (if present) are already in place, and we exit the vector loop exclusively to the middle block.

Returns true if the VPLiveOut uses scalars of operand Op.
