Constructor Detail

TreeCode

protected TreeCode(HMethod newMethod,
                   Tree tree,
                   Frame topframe,
                   TreeDerivation treeDerivation)

Method Detail

getTreeDerivation

public TreeDerivation getTreeDerivation()

Specified by:

getTreeDerivation in class Code

clone

public HCodeAndMaps<Tree> clone(HMethod newMethod,
                                Frame frame)

Clone this code representation. The clone has its own copy of the tree structure.

Specified by:

clone in class Code

getName

public String getName()

Return the name of this code view.

Specified by:

getName in class Code

Returns:

the string "tree".

isCanonical

public boolean isCanonical()

Description copied from class: Code

Returns true if this codeview is a canonical representation

Specified by:

isCanonical in class Code

Returns:

false

getGrapher

public CFGrapher<Tree> getGrapher()

CFGrapher not valid for non-canonical trees.

Overrides:

getGrapher in class Code

Returns:

null

getUseDefer

public UseDefer<Tree> getUseDefer()

UseDefer not valid for non-canonical trees.

Overrides:

getUseDefer in class Code

Returns:

null

recomputeEdges

public void recomputeEdges()

This operation is not supported in non-canonical tree forms.

Throws:

UnsupportedOperationException - always.

codeFactory

public static HCodeFactory codeFactory(HCodeFactory hcf,
                                       Frame frame)

Returns a code factory for TreeCode, given a code factory for LowQuadNoSSA or LowQuadSSI.
effects: if hcf is a code factory for LowQuadNoSSA or LowQuadSSI, then creates and returns a code factory for TreeCode. Else passes hcf to LowQuadSSI.codeFactory(), and reattempts to create a code factory for TreeCode from the code factory returned by LowQuadSSI.

LowQuadSSI.codeFactory(HCodeFactory)

codeFactory

public static HCodeFactory codeFactory(Frame frame)

Return a code factory for TreeCode, using the default code factory for LowQuadSSI
