This class represents the scheduled code. The main data structure is a map from scheduled cycle to instructions. During scheduling, the data structure explicitly represents all stages/iterations. When the algorithm finshes, the schedule is collapsed into a single stage, which represents instructions from different loop iterations.
Synopsis
Declared in <llvm/CodeGen/MachinePipeliner.h>
class SMSchedule;Description
The SMS algorithm allows negative values for cycles, so the first cycle in the schedule is the smallest cycle value.

Constructor |
Return the cycle for a scheduled instruction. This function normalizes the first cycle to be 0. |
|
Return the last cycle in the finalized schedule. |
|
Return the first cycle in the completed schedule. This can be a negative value. |
|
Return the initiation interval for this schedule. |
|
Return the instructions that are scheduled at the specified cycle. |
|
Return the maximum stage count needed for this schedule. |
|
Return true if the instruction is scheduled at the specified stage. |
|
Set the initiation interval for this schedule. |
|
Return the stage for a scheduled instruction. Return ‐1 if the instruction has not been scheduled. |
