Another GCC related project could be Rust RTEMS Support but I don't know
what that entails beyond turning it on and seeing what goes wrong. I
tried to build it last year and got far enough to decide to wait before
trying again.
Not sure how far you went. The process is generally:
(1) tune Rust compiler to cross-compile correctly for specific
hardware/os platform. So basically you get no_std capable compiler
(2) review, patch and by using (1) cross-compile libc
(3) using sources from (1) and (2) build full stage (std enabled) rustc.
(4) tweak and tune tools (rustup/cargo etc.) whenever required to smooth
sharp edges for RTEMS.
Here, I'm nearly finished with (1) for arm-rtems (e.g. cortex-aX not
cortex-mX).
