◆ DEBUG_TYPE
#define DEBUG_TYPE "pipeliner"
◆ createDedicatedExit()
Create a dedicated exit for Loop.
Exit is the original exit for Loop. If it is already dedicated exit, return it. Otherwise, insert a new block between them and return the new block.

◆ getInitPhiReg()
Return the Phi register value that comes from the incoming block.

◆ getLoopPhiReg()
Return the Phi register value that comes the loop block.

◆ getLoopPhiUser()
Return a phi if Reg is referenced by the phi.
canApply() guarantees that at most only one such phi exists.
