Hello, I found out recently, that when I have j-- pattern in cycle it is written in llvm code with the help of addition. I actually wanted to somehow check are we following descending or acceding pattern in cycle. Is this substitution of operations done always? or not? seems that in this case the only way to proceed is to check whether the operand is negative or not. -------------- next part -------------- An HTML attachment was scrubbed...
