getBot()

DGNode * llvm::sandboxir::SchedBundle::getBot

(

)

const

\Returns the bundle node that comes after the others in program order.

Definition at line 36 of file Scheduler.cpp.

References llvm::sandboxir::Instruction::comesBefore(), llvm::drop_begin(), llvm::sandboxir::DGNode::getInstruction(), and N.

getTop()

DGNode * llvm::sandboxir::SchedBundle::getTop

(

)

const

\Returns the bundle node that comes before the others in program order.

Definition at line 27 of file Scheduler.cpp.

References llvm::drop_begin(), llvm::sandboxir::DGNode::getInstruction(), and N.

isSingleton()

bool llvm::sandboxir::SchedBundle::isSingleton ( ) const

inline

Singleton bundles are created when scheduling instructions temporarily to fill in the schedule until we schedule the vector bundle.

These are non-vector bundles containing just a single instruction.

operator=()

SchedBundle & llvm::sandboxir::SchedBundle::operator= ( const SchedBundle & Other )

delete

Copy Assignment (unimplemented).

References llvm::Other, and SchedBundle().

ready()

bool llvm::sandboxir::SchedBundle::ready ( SchedDirection Dir ) const

inline

\Returns true if all nodes in the bundle are ready.
