176 The Planning Process and VPlan Roadmap
179 Transforming the Loop Vectorizer to use VPlan follows a staged approach. First,
180 VPlan is used to record the final vectorization decisions, and to execute them:
182 decisions taken inside basic-blocks. Next, VPlan will be used also as the basis
184 VPlan-to-VPlan algorithms. Finally, VPlan will support the planning process
198 In order for VPlan to support making instruction-level decisions and analyses,
