◆ DEBUG_TYPE

#define DEBUG_TYPE   "loop-vectorize"
  1. PlainCFGBuilder class: builds a plain VPBasicBlock-based CFG that faithfully represents the CFG in the incoming IR. A VPRegionBlock (Top Region) is created to enclose and serve as parent of all the VPBasicBlocks in the plain CFG. NOTE: At this point, there is a direct correspondence between all the VPBasicBlocks created for the initial plain CFG and the incoming BasicBlocks. However, this might change in the future.
