Arthur Cohen has posted a massive series of patches in four parts
(part 1,
part 2,
part 3,
part 4)
upstreaming all of the recent work on the GCC Rust front end. These
changes include the Polonius borrow checker, the foreign-function
interface, inline assembly support, if-let statement handling,
multiple built-in derive macros, for loops, and more.
