Classes

struct  llvm::MachineSchedContext
 MachineSchedContext provides enough context from the MachineScheduler pass for the target to instantiate a scheduler. More...
 
class  llvm::MachineSchedRegistry
 MachineSchedRegistry provides a selection of available machine instruction schedulers. More...
 
struct  llvm::MachineSchedPolicy
 Define a generic scheduling policy for targets that don't provide their own MachineSchedStrategy. More...
 
class  llvm::MachineSchedStrategy
 MachineSchedStrategy - Interface to the scheduling algorithm used by ScheduleDAGMI. More...
 
class  llvm::ScheduleDAGMI
 ScheduleDAGMI is an implementation of ScheduleDAGInstrs that simply schedules machine instructions according to the given MachineSchedStrategy without much extra book-keeping. More...
 
class  llvm::ScheduleDAGMILive
 ScheduleDAGMILive is an implementation of ScheduleDAGInstrs that schedules machine instructions while updating LiveIntervals and tracking regpressure. More...
 
class  llvm::ReadyQueue
 Helpers for implementing custom MachineSchedStrategy classes. More...
 
struct  llvm::SchedRemainder
 Summarize the unscheduled region. More...
 
class  llvm::SchedBoundary
 Each Scheduling boundary is associated with ready queues. More...
 
class  llvm::GenericSchedulerBase
 Base class for GenericScheduler. More...
 
struct  llvm::GenericSchedulerBase::CandPolicy
 Policy for scheduling the next instruction in the candidate's zone. More...
 
struct  llvm::GenericSchedulerBase::SchedResourceDelta
 Status of an instruction's critical resource consumption. More...
 
struct  llvm::GenericSchedulerBase::SchedCandidate
 Store the state used by GenericScheduler heuristics, required for the lifetime of one invocation of pickNode(). More...
 
class  llvm::GenericScheduler
 GenericScheduler shrinks the unscheduled zone using heuristics to balance the schedule. More...
 
class  llvm::PostGenericScheduler
 PostGenericScheduler - Interface to the scheduling algorithm used by ScheduleDAGMI. More...
