Committing to Rust for Kernel Code

I disagree that the language of the compiler doesn't matter. It absolutely matters in some cases, all of which are cases where (ANSI) C is pretty much the only option because of the inherent difficulty of C++ compilers.

This still doesn't explain why the language of the compiler matters. I could write a C compiler in Pony-lang targeting a 30-year-old MCU were I so inclined.

The available compilers targeting your microcontroller certainly matter, though. You certainly still find lots of options that aren't Rust-compatible, but a non-trivial number microcontrollers are ARM or RISC-V based now, and can be targeted by LLVM/Rust.

What target are you compiling to that gcc doesn't support?

Typically if this is the case, won't you be cross compiling for that target anyway?
