Constructor Detail

ConvertLIRtoMIR.DoBURS

private ConvertLIRtoMIR.DoBURS()
Method Detail

getName

public String getName()
Specified by:
getName in class CompilerPhase
Returns:
a String which is the name of the phase.

newExecution

public CompilerPhase newExecution(IR ir)
Description copied from class: CompilerPhase
This method is called immediately before performPhase. Phases that do not need to create a new instance for each execution may override this method to return this, but this must be done carefully! Classes that don't override this method need to override getClassConstructor.

Overrides:
newExecution in class CompilerPhase
Parameters:
ir - the IR that is about to be passed to performPhase
Returns:
an opt compiler phase on which performPhase may be invoked.

reportAdditionalStats

public void reportAdditionalStats()
Description copied from class: CompilerPhase
Called when printing a measure compilation report to enable a phase to report additional phase-specific statistics.

Overrides:
reportAdditionalStats in class CompilerPhase

verify

public void verify(IR ir)
Description copied from class: CompilerPhase
Verify the IR. Written as a non-final virtual method to allow late stages in the compilation pipeline (eg ConvertMIR2MC) to skip verification.

Overrides:
verify in class CompilerPhase
Parameters:
ir - the IR to verify

perform

public void perform(IR ir)
Description copied from class: CompilerPhase
This is the method that actually does the work of the phase.

Specified by:
perform in class CompilerPhase
Parameters:
ir - the IR on which to apply the phase
