This has the problem that now, fn x() {}
fn main() {
let s = [(); { loop {} }];
x();
}
Because dead_code assumes dead until proven live. Would it make more sense to do it at a finer grained level instead of the body? |
🤦 good point. Yea we can do it more fine-grained, but some ways to do that are effectively papering over some issues. I'll check if there is a reasonable way to do it |

… r=compiler-errors Gracefully handle missing typeck information if typeck errored fixes rust-lang#116893 I created some logs and the typeck of `fn main` is exactly the same, no matter whether the constant's body is what it is, or if it is replaced with `panic!()`. The latter will cause the ICE not to be emitted though. The reason for that is that we abort compilation if *errors* were emitted, but not if *lint errors* were emitted. This took me way too long to debug, and is another reason why I would have liked rust-lang/compiler-team#633

fixes #116893
I created some logs and the typeck of
fn main
is exactly the same, no matter whether the constant's body is what it is, or if it is replaced withpanic!()
. The latter will cause the ICE not to be emitted though. The reason for that is that we abort compilation if errors were emitted, but not if lint errors were emitted. This took me way too long to debug, and is another reason why I would have liked rust-lang/compiler-team#633
