I suspected something like that. :(
I was hoping i could run the program and step throught IR-Code line by line, maybe even have a look at the variables.
Well, what about compiling it into assembler-code. Is there any way to know which IR-line generated which assembler line(s)? (I do not need any optimizations or whatever, if that helps...)
