A Rust-in-GCC update

Post Syndicated from original https://lwn.net/Articles/899385/

Philip Herron has posted an update on the status of the GCC front-end
compiler for the Rust language.

For some context, my current project plan brings us to November
2022 where we (unexpected events permitting) should be able to
support valid Rust code targeting Rustc version ~1.40 and reuse
libcore, liballoc and libstd. This date does not account for the
borrow checker feature and the proc macro crate, which we have a
plan to implement, but this will be a further six-month project.
