Hi,

Cases 1 and 2 are transformed as asked by -fgraphite-identity.

Case 3 is not recognized by graphite because there is a condition
that depends on a data reference.  This will be fixed in a future
version of Graphite that handles these conditions as predicates.
See 
http://gcc.gnu.org/wiki/Graphite_Workshop_Nov08?action=AttachFile&do=view&target=graphite_irregular_cf.pdf

I added the 3 testcases to the graphite testsuite, case 3 is XFAILed.

Sebastian
