Ta.  Updated to:

"CLooG can use many different backends.  CLooG 0.16 with the ISL

Are you getting an error?  If so, please let me know, or file a bug,
or ask in #bzr.

* libauqntum - running the SMSed version on ARM machine did not show
significant improvement. Discussed it with Richard Sandiford.
Apparently in the SMS phase the instructions are of DI mode due to the
fact the loop contains 64 bit operations while they later been
generated as 32 bit operations. This makes SMS less accurate and I'm
now looking into a version which disables DI mode operations.
* Started to look at the potential of SMS on libav. Initial runs of
Richard's microbenchmarks with SMS show some regressions as well as
improvements that I'm looking at.
