There is some additional clean up that could be done to remove prefetch read/write intrinsics hooked up to older versions of Unsafe: do_intrinsic(_prefetchRead, sun_misc_Unsafe, prefetchRead_name, prefetch_signature, F_RN) \ do_name( prefetchRead_name, "prefetchRead") \ do_intrinsic(_prefetchWrite, sun_misc_Unsafe, prefetchWrite_name, prefetch_signature, F_RN) \ do_name( prefetchWrite_name, "prefetchWrite") \ do_intrinsic(_prefetchReadStatic, sun_misc_Unsafe, prefetchReadStatic_name, prefetch_signature, F_SN) \ do_name( prefetchReadStatic_name, "prefetchReadStatic") \ do_intrinsic(_prefetchWriteStatic, sun_misc_Unsafe, prefetchWriteStatic_name, prefetch_signature, F_SN) \ do_name( prefetchWriteStatic_name, "prefetchWriteStatic") \ That will also require updates in various other files. I presume these prefetch methods are never used throughout the runtime? Paul.
