Yes. I gave another read now and found out the FileCheck guide to solve some of my doubts. 
I will need to double check also the llvm IR generation, if everything is ok, I should be able to modify the test quickly.
As of now I am for a bit more than a week away from pc, but as soon as I am back I will finish this pr.

thank you for your help, I'll be posting soon :)
