claw.tatsu.primitive.Field

public final class Field
extends java.lang.Object

Primitive transformation and test applied to fields. This included: - Scalar and array promotion (promote). - Adaptation of scalar reference to array reference for promoted scalar. - Adaptation of allocate statement for promoted field. - Demote array reference to fewer dimension or scalar.

Method Detail

promote

public static void promote(PromotionInfo fieldInfo,
                           FfunctionDefinition fctDef,
                           XcodeProgram xcodeml)
                    throws IllegalTransformationException

Promote a field with the information stored in the defined dimensions.

Parameters:

fieldInfo - Promotion information. Must contains identifier and dimensions.

fctDef - Function definition node in which the promotion is performed.

xcodeml - Current XcodeML translation unit.

Throws:

IllegalTransformationException - If promotion information are not sufficient. If types cannot be found in typeTable.

adaptScalarRefToArrayRef

public static void adaptScalarRefToArrayRef(java.lang.String identifier,
                                            FfunctionDefinition fctDef,
                                            java.util.List<DimensionDefinition> dims,
                                            XcodeML xcodeml)

Adapt all the array references of the variable in the data clause in the current function/subroutine definition.

Parameters:

identifier - List of array identifiers that must be adapted.

fctDef - Function definition in which reference are changed.

dims - Dimension definition to use for array index generation.

xcodeml - Current XcodeML program unit in which the element will be created.

adaptAllocate

public static void adaptAllocate(PromotionInfo promotionInfo,
                                 Xnode parent,
                                 XcodeProgram xcodeml)

Adapt allocate statement with given dimension.

Parameters:

promotionInfo - Promotion information. Must contains identifier and dimensions.

parent - Root node from which allocate statements are looked for.

xcodeml - Current XcodeML translation unit.

demoteToScalar

public static void demoteToScalar(Xnode arrayRef)
                           throws IllegalTransformationException

Demote an array reference to a var reference.

Parameters:

arrayRef - The array reference to be modified.

Throws:

IllegalTransformationException - If node is null or not an FarrayRef.

demote

public static void demote(Xnode arrayRef,
                          java.util.List<java.lang.Integer> keptDimensions)
                   throws IllegalTransformationException

Demote an array reference to a reference with fewer dimensions.

Parameters:

arrayRef - The array reference to be modified.

keptDimensions - List of dimensions to be kept. Dimension index starts at 1.

Throws:

IllegalTransformationException - If node is null or not an FarrayRef.

reshape

public static void reshape(FfunctionDefinition fctDef,
                           ReshapeInfo reshapeInfo,
                           XcodeProgram xcodeml)
                    throws IllegalTransformationException

Reshape field in function definition.

Parameters:

fctDef - Function definition.

reshapeInfo - Reshape information.

xcodeml - Current XcodeML/F translation unit.

Throws:

IllegalTransformationException - If reshape cannot be done.

adaptArrayRef

public static void adaptArrayRef(PromotionInfo promotionInfo,
                                 Xnode parent,
                                 XcodeProgram xcodeml)
