Chen Yang updated HARMONY-5398:
-------------------------------

    Description: Current JIT cannot apply the array copy optimization as in non-generational
mode, but relies on current array_copy implementation in harmonyvm, which results in poor
performance. In order to achieve better performance, inlined array copy optimization in JIT
is preferred, at least for those non reference array.   (was: Current JIT cannot apply the
array copy optimization as in non-generational mode, but relies on current array_copy implementation
in harmonyvm, which results in poor performance. In order to achieve better performance, inlined
array copy optimization is preferred, at least for those non reference array. )
    Environment: All supported environment  (was: All affected version)
        Summary: Enable array copy optimization for generational mode in JIT  (was: Enable
array copy optimization in generational mode)
