ScheduleHazardRecognizer::HazardType SPUHazardRecognizer::getHazardType

(

SUnit *

SU

)

[virtual]

Return the pipeline hazard type encountered or generated by this instruction. Currently returns NoHazard.

Returns:

NoHazard

void SPUHazardRecognizer::EmitInstruction

(

SUnit *

)

[virtual]

EmitInstruction - This callback is invoked when an instruction is emitted, to advance the hazard state.

Reimplemented from llvm::ScheduleHazardRecognizer.

Definition at line 126 of file SPUHazardRecognizers.cpp.

void SPUHazardRecognizer::AdvanceCycle

(

)

[virtual]

AdvanceCycle - This callback is invoked when no instructions can be issued on this cycle without a hazard. This should increment the internal state of the hazard recognizer so that previously "Hazard" instructions will now not be hazards.

Reimplemented from llvm::ScheduleHazardRecognizer.

Definition at line 130 of file SPUHazardRecognizers.cpp.

void SPUHazardRecognizer::EmitNoop

(

)

[virtual]

EmitNoop - This callback is invoked when a noop was added to the instruction stream.

Reimplemented from llvm::ScheduleHazardRecognizer.

Definition at line 135 of file SPUHazardRecognizers.cpp.
