Public Member Functions | |
EntryStage (SourceMgr &SM) | |
bool | isAvailable (const InstRef &IR) const override |
Returns true if it can execute IR during this cycle. | |
bool | hasWorkToComplete () const override |
Returns true if some instructions are still executing this stage. | |
Error | execute (InstRef &IR) override |
The primary action that this stage performs on instruction IR. | |
Error | cycleStart () override |
Called once at the start of each cycle. | |
Error | cycleResume () override |
Called after the pipeline is resumed from pausing state. | |
Error | cycleEnd () override |
Called once at the end of each cycle. | |
