Stewart Gordon: > What are "normal cases"?
It means "very simple cases". Things like fibonacci / factorial functions that call themselves at the tail. Generally it's a fragile optimization, it's easy for it to not work/stop working. LLVM used to perform this optimization, then it stopped working for months an no one noticed. I have written a bug report and they have made it work again. And then they have put it in their demo :-) http://llvm.org/demo/ Bye, bearophile
