Class OpenAccContinuation

java.lang.Object

claw.shenron.transformation.Transformation

claw.wani.transformation.ClawTransformation

claw.wani.transformation.internal.OpenAccContinuation

public class OpenAccContinuation
extends ClawTransformation

 OpenACC line continuation transformation. The XcodeML/F pragma statement
 representation is an aggregated version of the pragma with all its continuation
 lines.
 As those directives are not handled by the CLAW XcodeML to XcodeML
 translator, they must be output in a correct way. This transformation divides
 the XcodeML representation back to a multi-line pragma definition.

 Example:
 The followings OpenACC directives in Fortran code:

   !$acc data &
   !$acc present (a,b,c,d,e,f,g)

 are represented in XcodeML with

 <FpragmaStatement>acc data present (a,b,c,d,e,f,g)</FpragmaStatement>

 Based on the defined max columns, the pragma statement will be splitted.

Constructor Detail

OpenAccContinuation

public OpenAccContinuation(ClawPragma directive)

Constructs a new OpenACC continuation triggered from a specific pragma.

Parameters:

directive - The directive that triggered the OpenACC continuation transformation.

Method Detail

analyze

public boolean analyze(XcodeProgram xcodeml,
                       Translator translator)

Check if the directive starts with the OpenACC prefix.

Specified by:

analyze in class Transformation

Parameters:

xcodeml - The XcodeML on which the transformations are applied.

translator - The translator used to applied the transformations.

Returns:

True the directive starts with the OpenACC prefix.

canBeTransformedWith

public boolean canBeTransformedWith(XcodeProgram xcodeml,
                                    Transformation other)

Description copied from class: Transformation

Check whether the current transformation can be transformed together with the given transformation. Useful only for dependent transformation.

Specified by:

canBeTransformedWith in class Transformation

Parameters:

xcodeml - The XcodeML on which the transformations are applied.

other - The other transformation part of the dependent transformation.

Returns:

Always false as independent transformation are applied one by one.

transform

public void transform(XcodeProgram xcodeml,
                      Translator translator,
                      Transformation transformation)
               throws IllegalTransformationException

Apply the OpenACC continuation transformation.

Specified by:

transform in class Transformation

Parameters:

xcodeml - The XcodeML on which the transformations are applied.

translator - The translator used to applied the transformations.

transformation - Not used in this transformation

Throws:

IllegalTransformationException - if the transformation cannot be applied.

abortOnFailedAnalysis

public boolean abortOnFailedAnalysis()

Description copied from class: Transformation

Tells whether the transformation should abort the translation if the analysis fails. Default behavior is to abort.

Overrides:

abortOnFailedAnalysis in class Transformation

Returns:

True if it aborts. False otherwise.
