Ok, I'll take a look at that too.

The gimple_call_set_ctrl_altering approach is looking good for the moment.

Richard, if that works out, so we only have to check unique_p on the last insn 
of a bb, does that satisfy your concerns?  (Of course I'll repost patch 1 for 
review).

WRT the other patches I think the status is:

01-trunk-unique.patch
   Internal function with a 'uniqueness' property
   * reworking as described.
02-trunk-nvptx-partition.patch
   NVPTX backend patch set for partitioned execution
   * approved with minor edits
03-trunk-hook.patch
   OpenACC hook
   * approved with minor edit
04-trunk-c.patch
   C FE changes
   * Being addressed by Cesar
05-trunk-cxx.patch
   C++ FE changes
   * Being addressed by Cesar
06-trunk-red-init.patch
   Placeholder to keep reductions functioning
   * Approved
07-trunk-loop-mark.patch
   Annotate OpenACC loops in device-agnostic manner
   * Addressing minor comments
08-trunk-dev-lower.patch
   Device-specific lowering of loop markers
   * Question asked & answered about non-ptx behaviour
09-trunk-lower-gate.patch
   Run oacc_device_lower pass regardless of errors
   * Approved
10-trunk-libgomp.patch
   Libgomp change (remove dimension check)
   * Approved
11-trunk-tests.patch
   Initial set of execution tests
   * Approved, but C& C++ error tests needed

I'll repost:
01-trunk-unique.patch
   Internal function with a 'uniqueness' property

That has some obvious knock on changes to 02, 07 and 08, do you want those 
reposted for review?

Cesar will repost:
04-trunk-c.patch
   C FE changes
05-trunk-cxx.patch
   C++ FE changes

The remaining patch:
08-trunk-dev-lower.patch
   Device-specific lowering of loop markers

seems to be waiting on Jakub?
