Unsafe.{get,put}-X-Unaligned performance (original) (raw)

Also,

static boolean unaligned() { 595 if (unalignedKnown) 596 return unaligned; 597 unaligned = unsafe.unalignedAccess();

598 unalignedKnown = true; 599 return unaligned; 600 }

I don't think we need this unalignedKnown dance anymore -- just return unsafe.unalignedAccess() there?
