miri subtree update by RalfJung · Pull Request #161729 · rust-lang/rust

RalfJung · 2026-08-25T08:40:52Z

I want to add proper vararg checks for Miri's shims but it turns out I'll have to adjust the rustc side for this. It'll be easier to just do the entire thing as a rustc patch, but that needs a sync first.

Subtree update of miri to rust-lang/miri@40000c5.

Created using https://github.com/rust-lang/josh-sync.

…when-reliable run `f16` and `f128` tests natively when reliable

…line

unify shim_sig and shim_sig_variadic macros

Custom allocators do not get noalias after all

This updates the rust-version file to 9bb55c8.

miri is developed in its own repository. If the Miri part of this change can be broken out, consider making this change to rust-lang/miri instead. However, if Miri needs adjusting for rustc changes, just ignore this message.
