Examples with PromotionInfo cx2x.translator.transformation.claw.parallelize.PromotionInfo used on opensource projects

Example 1 with PromotionInfo

use of cx2x.translator.transformation.claw.parallelize.PromotionInfo in project claw-compiler by C2SM-RCM.

the class TransformationHelper method promoteField.

/**
   * Promote a field with the information stored in the defined dimensions.
   *
   * @param fieldId   Id of the field as defined in the symbol table.
   * @param update    If true, update current type otherwise, create a type from
   *                  scratch.
   * @param assumed   If true, generate assumed dimension range, otherwise, use
   *                  the information in the defined dimension.
   * @param overIndex Over clause to be used for promotion.
   * @param xcodeml   Current XcodeML program unit in which the element will be
   *                  created.
   * @param overPos   Force behavior as if over clause is present.
   * @throws IllegalTransformationException If type cannot be found.
