    XMLWordPrintable

Details

    • b20

    Description

      Following "indexVector" can be implemented with vector instructions on most of the platforms.
      Adding hotspot intrinsifaction implementation benefits some APIs like "VectorMask.indexInRange".

      // FIXME @IntrinsicCandidate
          public static
          <V extends Vector<E>,
           E,
           S extends VectorSpecies<E>>
          V indexVector(Class<? extends V> vClass, Class<E> eClass,
                        int length,
                        V v, int step, S s,
                        IndexOperation<V, S> defaultImpl) {
              assert isNonCapturingLambda(defaultImpl) : defaultImpl;
              return defaultImpl.index(v, step, s);
          }
