  • Constructor Details

    • AbstractCOptimizer

      public AbstractCOptimizer()
      Create a C AST optimizer.

  • Method Details

    • getMasterOptimizer

      public ICMasterOptimizer getMasterOptimizer()
      Description copied from interface: IOptimizer
      Retrieve the optional master optimizer that manages this optimizer.
      Specified by:
      getMasterOptimizer in interface IOptimizer<ICMethod>
      Overrides:
      getMasterOptimizer in class AbstractOptimizer<ICMethod>
      Returns:
      optional reference

    • getMasterOptimizerSafe

      protected ICMasterOptimizer getMasterOptimizerSafe()
      Safely retrieve a master optimizer. If getMasterOptimizer() provides one, it is returned. Else, an empty immutable generic MO is provided.
      Returns:
      never null

    • performOnTarget

      public final int performOnTarget(ICMethod m)
      Description copied from interface: IOptimizer
      Perform the optimization pass.
      Specified by:
      performOnTarget in interface IOptimizer<ICMethod>
      Parameters:
      m - target to optimize
      Returns:
      the number of optimizations performed; if negative, an error has occurred and the optimizing process should be aborted

    • perform

      protected abstract int perform()
      Perform the optimizer-specific work.
      Returns:
      the number of optimizations performed
