GC-parseable element atomic memcpy/memmove
...ource/destination objects on a safepoint. In order to do this we need
to know the base pointers as well. How do we make the base pointers
available in the copy routine? I suggest we add them explicitly as
arguments during lowering.
For example:
__llvm_memcpy_element_unordered_atomic_safepoint_1(
dest_base, dest_derived, src_base, src_derived, length)
It will be up to RS4GC to do the new lowering and prepare the arguments.
RS4GC knows how to compute base pointers for a given derived pointer.
It also already does lowering for deoptimize intrinsics by replacing
an intrinsic call with a symbol call. So...

[PATCH v6 00/16] xen: arm: 64-bit guest support and domU FDT autogeneration
Biggest change is to switch the new DTB node to /xen-core-devices
instead of /xen at Stefano''s request.
I also dropped the few patches title HACK etc which weren''t supposed to
be there and fixed up some bits and pieces which folks commented on.
George, WRT the freeze I think this is functionality which we cannot
ship Xen 4.4 without. The impact is entirely constrained to the
