| ModuloSchedule (MachineFunction &MF, MachineLoop *Loop, std::vector< MachineInstr * > ScheduledInstrs, DenseMap< MachineInstr *, int > Cycle, DenseMap< MachineInstr *, int > Stage) | |
| Create a new ModuloSchedule. | |
| MachineLoop * | getLoop () const |
| Return the single-block loop being scheduled. | |
| int | getNumStages () const |

Represents a schedule for a single-block loop.
For every instruction we maintain a Cycle and Stage.
Definition at line 80 of file ModuloSchedule.h.
Create a new ModuloSchedule.
- ScheduledInstrs The new loop instructions, in total resequenced order.
- Cycle Cycle index for all instructions in ScheduledInstrs. Cycle does not need to start at zero. ScheduledInstrs must be partially ordered by Cycle.
- Stage Stage index for all instructions in ScheduleInstrs.
