> The Vector API toShuffle method can be optimized using existing vector > conversion intrinsic. > > The following changes are made: > 1) vector.toShuffle java implementation is changed to call > VectorSupport.convert. > 2) The conversion intrinsic (inline_vector_convert()) in vectorIntrinsics.cpp > is changed to allow shuffle as a destination type. > 3) The shuffle.toVector intrinsic (inline_vector_shuffle_to_vector()) in > vectorIntrinsics.cpp now explicitly generates conversion node instead of > performing conversion during unbox. This is to remove unnecessary boxing > during back to back vector.toShuffle and shuffle.toVector calls. > > Best Regards, > Sandhya
