Hi everyone, This patchset is the first of four similarly-sized patchsets aimed at updating upstream with our most recent changes to the Rust frontend.
We plan on upstreaming small patchsets every week up to the release of 15.1. This first set's main change is the addition of the polonius borrow-checker to the compiler, as well as all of the infrastructure required for FFI and interacting with Rust crates in general. As such, an installation of the Rust programming language is now required for building the Rust frontend to GCC. As a reminder, this change is temporary and we are working hard towards supporting enough of the language that we can bootstrap our own requirements. This patchset also adds some support for inline assembly by taking inspiration from the C frontend. There are also numerous changes for supporting the Rust core library, such as handling more attributes, handling negative trait implementations, built-in derive macros, and more. I will be following up with the next three patchsets in the coming days. Best, Arthur
