Hi Frank,

this is interesting and I do not yet understand what is going on here. 
Let me shoot some first guesses:

Which 'opt' are you runnning. Did you run:

~/toolchain/install/llvm-3.8/bin/opt -load 
~/toolchain/install/llvm-3.8/lib/libPolly.so

or rather some

/usr/local/bin/opt -load ~/toolchain/install/llvm-3.8/lib/libPolly.so

Also, what does:

~/toolchain/install/llvm-3.8/bin/opt -load 
~/toolchain/install/llvm-3.8/lib/libPolly.so -help-hidden | grep 
canonicalize give you?

Best,
Tobias
