for _ in 0..x makes non-inlined call to Range::next()

[kornelski]

Looks like bug #41097

fn main() {
    for _ in 0 .. 100 {}
}

Translates to non-inlined calls to Range::next(): https://rust.godbolt.org/z/jZ62Td

There is a missing optimisation flag in your reproducer. With -O the inlining happens and the end result is a function that does a leaf return.

Closing. Complain if you feel I was wrong and we’ll reopen.

Ouch, sorry! I assumed godbolt had it on by default :/
