-Zlocation-detail=none

[kornelski]

There's a nightly flag rust-lang/rust#89920 that removes file/line/column information from panics and [track_caller]. Apart from reduction in the location data, this sometimes also lets the compiler unify code paths of multiple panics into one.

Thanks @kornelski!

Do you know if this affects panic = "abort" or -Z build-std-features=panic_immediate_abort?

[kornelski]

It helps with panic=abort (locations are still printed), but is mostly unnecessary when using panic_immediate_abort (std inlines panic code, and the locations are optimized out). It's still possible to use caller locations for non-panicking code, e.g. tokio collects them for showing task locations in tokio-console.
