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?

Overrides:: shouldPerform in class CompilerPhase

Parameters:: options - the compiler options for the compilation
Returns:: true if SSA-based global code placement or SSA-based global common subexpression elimination are enabled

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
