It is with great satisfaction that I can announce that Attila and I are done
with the completely immutable IR. We have as a proof of concept also removed
Node.CopyState altogether. There can now be copies of the same reference node
in the IR and that is OK. This saves memory and ensures that we can clone code
correctly (i.e. with a meaningless operation, rather than with the deep clone
that was afflicted with literally dozens of bugs).
All IR changes are now copy on write - which create new nodes. This is the
responsibility of the caller.
Everything runs.
Individual patches are at http://cr.openjdk.java.net/~lagergren/8010701/ if the
webrev is too much
