Method Detail

newExecution

public CompilerPhase newExecution(IR ir)

Return this instance of this phase. This phase contains no per-compilation instance fields.

Overrides:

newExecution in class CompilerPhase

Parameters:

ir - not used

Returns:

this

shouldPerform

public final boolean shouldPerform(OptOptions options)

Should this phase perform?

Perform only if global code placement or global common subexpression elimination are performed.

Overrides:

shouldPerform in class CompilerPhase

Parameters:

options - the compiler options for the compilation

Returns:

true if the phase should be performed

getName

public final String getName()

Return the name of the phase

Specified by:

getName in class CompilerPhase

Returns:

a String which is the name of the phase.

perform

public final 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
