Hi Andrew,

this is interesting. This suggest that LLVM does not need canonical 
induction variables any more or that they are created somewhere else.

Can you explain why we do not need this anymore and if there would be 
another preferable way to get something similar. (I use in Polly 
canonical induction variables)

Cheers
Tobi
