Member Function Documentation

◆ initialize()

void R600SchedStrategy::initialize ( ScheduleDAGMI DAG)
overridevirtual

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

Implements llvm::MachineSchedStrategy.

Definition at line 27 of file R600MachineScheduler.cpp.

References assert(), llvm::R600Subtarget::getTexVTXClauseSize(), llvm::AMDGPUSubtarget::hasCaymanISA(), llvm::ScheduleDAGMI::hasVRegLiveness(), and llvm::ARM_MB::ST.

◆ pickNode()

SUnit * R600SchedStrategy::pickNode ( bool IsTopNode)
overridevirtual

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 57 of file R600MachineScheduler.cpp.

◆ releaseBottomNode()

void R600SchedStrategy::releaseBottomNode ( SUnit SU)
overridevirtual

◆ releaseTopNode()

void R600SchedStrategy::releaseTopNode ( SUnit SU)
overridevirtual

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

Implements llvm::MachineSchedStrategy.

Definition at line 192 of file R600MachineScheduler.cpp.

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

◆ schedNode()

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

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

Implements llvm::MachineSchedStrategy.

Definition at line 144 of file R600MachineScheduler.cpp.
