Aaaha:) I must say, one reason, why I'd like to have it wrapped is
that VarHandle.get/set do not have fixed typed signature.
Helper.longAt(arr, index)

Hi,
thank you for response!

On the other side, this would be easier to use and understand than
Hi,
what do you thing about adding helper methods for this kind of VarHandle?
It would be nice to have something like
Long.getFrom[LE/BE](byte[] arr, int index) // LE/BE -> endianity
Long.setTo[LE/BE](long val, byte[] arr, int index)
or
Arrays.getLongFrom[LE/BE](byte[] arr, int
Hi guys,
I have looked at generated asm, it does not seem there is problem, only
little different order
of shifts and ands.. Plus, at haswell, times do not differ so much. Here
are different parts:
Slower version:

Hello!
I have a small patch to Integer and Long classes, which is speeding up bit
reversion significantly.
Last two/three steps of bit reversion are doing byte reversion, so there is
possibility to use
intrinsified method reverseBytes. Java implementation of reverseBytes is
similar to those
