What Hacker News says
5 sourcesYeah, there's progress on 8-bit and 16-bit support. We're tracking our work on improving Rust for embedded systems in this roadmap issue [1], with details in this RFC repo [2]. As part of that, we have preliminary support for the 16 bit cpu MSP430 in-tree [3], and a fork for the 8-bit AVR in [4].

In Discover the world of microcontrollers through RustWell, the AVR backend is being actively developed, I have no idea how good it is. (Although some tooling for embedded systems is rather poor, so one would imagine that LLVM with the right heuristics couldn't do badly).
rustc is apparently (https://github.com/rust-embedded/rfcs/issues/3) not far of it being usable.
However, I don't regularly write code for uC-ers - and when I do, it's usually simple enough to be in assembly - so I can't really say anymore than that.
In LLVM 5.0.0 ReleaseThere is some discussion on that here:
https://github.com/rust-embedded/rfcs/issues/23
In Ownership is Theft: Experiences Building an Embedded OS in Rust (2015) [pdf]Rust has Tier 2 support[0] for ARMv6 to ARMv8 and Tier 3 support[1], so there are experimental limited[2] backends for the various Cortex in Tier 3.
However the ESP8266 is built around Tensilica's Xtensa, not ARM's Cortex. There currently is no support whatsoever for Xtensa in LLVM (let alone in Rust).
Current microcontroller work is on MSP430[3] with work being planned for Amtel AVR[4] since the AVR branch was merged into LLVM in November 2016. Xtensa is quite literally nowhere[5].
