Member Function Documentation

void R600SchedStrategy::initialize ( ScheduleDAGMI *  DAG )

virtual

Initialize the strategy after building the DAG for a new region.

Implements llvm::MachineSchedStrategy.

SUnit * R600SchedStrategy::pickNode ( bool &  IsTopNode )

virtual

Pick the next node to schedule, or return NULL. Set IsTopNode to true to schedule the node at the top of the unscheduled region. Otherwise it will be scheduled at the bottom.

Implements llvm::MachineSchedStrategy.

Definition at line 58 of file R600MachineScheduler.cpp.

void R600SchedStrategy::releaseBottomNode ( SUnit *  SU )

virtual

When all successor dependencies have been resolved, free this node for bottom-up scheduling.

Implements llvm::MachineSchedStrategy.

References llvm::dbgs(), DEBUG, llvm::SUnit::dump(), llvm::SUnit::getInstr(), and isPhysicalRegCopy().

void R600SchedStrategy::releaseTopNode ( SUnit *  SU )

virtual

When all predecessor dependencies have been resolved, free this node for top-down scheduling.

Implements llvm::MachineSchedStrategy.

Definition at line 189 of file R600MachineScheduler.cpp.

References llvm::dbgs(), DEBUG, and llvm::SUnit::dump().

void R600SchedStrategy::schedNode ( SUnit *  SU, bool  IsTopNode  )

virtual

Notify MachineSchedStrategy that ScheduleDAGMI has scheduled an instruction and updated scheduled/remaining flags in the DAG nodes.

Implements llvm::MachineSchedStrategy.

Definition at line 141 of file R600MachineScheduler.cpp.
