SubsPtrTransformation(HirRoot pHirRoot)

メソッドの概要

java.util.ArrayList	listUpPtrNodes(HIR pHir) listUpPtrNodes makes an array-list of pointer expressions taking the form (contents (add (decay ) (exp ) ) ) in pHir in the order of pre-visiting depth-first order.
java.util.ArrayList	listUpSubsNodes(HIR pHir) listUpSubsNodes makes an array-list of Subs nodes in pHir in the order of pre-visiting depth-first order.
boolean	ptrToSubsTransformation(HIR pHir, java.util.Map pPtrSubsCorrespondence) ptrToSubsTrasnsformation Transform pointer expression in pHir to subscript expression if the pointer expression is recorded in pPtrSubsCorrespondence or it is an expression representing simple subscripted expression.
boolean	subsToPtrTrasnsformation(HIR pHir, java.util.Map pPtrSubsCorrespondence) subsToPtrTrasnsformation Transform subscripted expression in pHir to pointer expression and record its correspondence to pPtrSubsCorrespondence.

メソッドの詳細

listUpSubsNodes

public java.util.ArrayList listUpSubsNodes(HIR pHir)

listUpSubsNodes makes an array-list of Subs nodes in pHir in the order of pre-visiting depth-first order.

パラメータ:

pHir - the subtree to be searched (usually HIR-body of subprogram).

戻り値:

the array-list of Subs nodes.

subsToPtrTrasnsformation

public boolean subsToPtrTrasnsformation(HIR pHir,
                                        java.util.Map pPtrSubsCorrespondence)

subsToPtrTrasnsformation Transform subscripted expression in pHir to pointer expression and record its correspondence to pPtrSubsCorrespondence.

パラメータ:

pHir - HIR subtree to be transformed.

pPtrSubsCorrespondence - record the Subs-Ptr correspondence.

戻り値:

true if some expression is transformed, false if no expression is transformed.

ptrToSubsTransformation

public boolean ptrToSubsTransformation(HIR pHir,
                                       java.util.Map pPtrSubsCorrespondence)

ptrToSubsTrasnsformation Transform pointer expression in pHir to subscript expression if the pointer expression is recorded in pPtrSubsCorrespondence or it is an expression representing simple subscripted expression.

パラメータ:

pHir - HIR subtree to be transformed.

pPtrSubsCorrespondence - show the Subs-Ptr correspondence.

戻り値:

true if some expression is transformed, false if no expression is transformed.

listUpPtrNodes

public java.util.ArrayList listUpPtrNodes(HIR pHir)

listUpPtrNodes makes an array-list of pointer expressions taking the form (contents (add (decay ) (exp ) ) ) in pHir in the order of pre-visiting depth-first order.

パラメータ:

pHir - the subtree to be searched (usually HIR-body of subprogram).

戻り値:

the array-list of contents-nodes.
