mrustc (a handwritten Rust compiler in C++) is already used for that in Guix and likely other distros: https://guix.gnu.org/blog/2018/bootstrapping-rust/ This would have other benefits though, as it's both a second bootstrapping path and could potentially compile Rust programs for platforms not supported by LLVM

Guix uses mrustc for bootstrapping Rust, as required for compiler packages; it's a really impressive project and has worked well in that role for some time. This new project is interesting for other reasons though, because mrustc is targeted at the de fact "subset" of Rust in use by rustc at any given time. This looks like it could have broader applications, like compiling Rust programs for platforms not supported by LLVM. If it really targets ANSI C (C89 or so), that's potentially many more platforms than are possible with ordinary rustc

This is also not guaranteed to be adopted widely, but the RISC-V Server Platform Specification was recently standardized with mandatory UEFI and ACPI support: https://github.com/riscv-non-isa/riscv-server-platform/relea... I'd rather have OpenFirmware like enterprise POWER, but anything is better than static device trees.

this seems to be how PEG parsing became popular during the last couple of decades, for example; see https://bford.info/pub/lang/peg/ (peg.pdf p11: "This work is inspired by and heavily based on Birman’s TS/TDPL and gTS/GTDPL systems [from the 1970s ...] Unfortunately it appears TDPL and GTDPL have not seen much practical use, perhaps in large measure because they were originally developed and presented as formal models [...]")
