we will be updating the system toolchain to #LLVM 18 later today

alongside it there will be an assortment of related updates (e.g. rust 1.77) and some other enhancements (cross runtimes for 32-bit armv6 and armv7)

> add LLVM CFI and cross-language LLVM CFI (and LLVM KCFI and cross-language LLVM KCFI) to the Rust compiler as part of our work in the Rust Exploit Mitigations Project Group. This is the first cross-language, fine-grained, forward-edge control flow protection implementation for mixed-language binaries that we know of.

Really interesting project.
