◆ DEBUG_TYPE
| #define DEBUG_TYPE "pipeliner" |
Definition at line 22 of file ModuloSchedule.cpp.
Function Documentation
◆ createDedicatedExit()
|
static |
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()
|
static |
Return the Phi register value that comes from the incoming block.
Definition at line 56 of file ModuloSchedule.cpp.
References Register.
◆ getLoopPhiReg()
|
static |
Return the Phi register value that comes the loop block.
Definition at line 64 of file ModuloSchedule.cpp.
References Register.
◆ getLoopPhiUser()
|
static |
Return a phi if Reg is referenced by the phi.
canApply() guarantees that at most only one such phi exists.

◆ getPhiRegs()
|
static |
Return the register values for the operands of a Phi instruction.
This function assume the instruction is a Phi.
