rust-lang/rust@9a2d1fdb14 Following commit 401dd84 in the Rust project (https://github.com/rust-lang/rust), ErrorGuaranteed was replaced by fatal errors. As a result, tcx.analysis() now aborts directly instead of returning an error guard. To accommodate this change, this update replaces tcx.analysis() with typeck() to perform type checking in the example.

The failing audit check will be fixed once #3992 is merged.

[zhassan-aws]

There is a performance regression in an s2n-quic benchmark that I was trying to investigate (s2n-quic/quic/s2n-quic-core/inet::checksum::tests::differential). The job summary indicates that it regressed by 112%:

kani_new	kani_old	Diff
315.40433	148.71283	+112.090%

[carolynzech]

@zhassan-aws I wonder if #3995 will improve this? May be worth investigating so that we don't spend time debugging a performance regression for an old version.

[zhassan-aws]

One of the recent s2n-quic CI runs shows that the runtime still exceeds 4 minute: https://github.com/aws/s2n-quic/actions/runs/14318410657/job/40129789750 EDIT: Never mind, the indicated CI run uses the previous version of Kani which doesn't include this toolchain upgrade.

A runtime increase occurred in the past for this harness due to changes in the standard library: #3030

This toolchain upgrade includes changes in the same functions: rust-lang/rust@e332aa89a7 which is what made me doubt the regression is not due to noise.
