ICE when specific compilation optimization passes are enabled/disabled about rust HOT 4 CLOSED

Check if there is an is_enabled method in the MirPass impl in https://github.com/rust-lang/rust/blob/master/compiler/rustc_mir_transform/src. If not, it will not be disabled with -Zmir-opt-level=0 and disabling it manually may cause issues like this. -Zmir-opt-level=0 disables all optimization passes, but not correctness passes like CriticalCallEdges.

The CriticalCallEdges pass is a mandatory part of lowering MIR into something that codegen can handle. You disabled it with -AddCallGuards however.

So, there are some passes that can't be disabled, right? I thought that when mir-opt level was set to 0, all passes were disabled. And may I ask which passes may have a similar problem if they are disabled?

Oh I see. Thank you so much!
