There is, it seems, an LLVM backend for Z80:
https://github.com/jacobly0/llvm-project
(see the 'z80' branch)
It appears TI calculators are the main use case.
I don't know the current status/functionality, but it would be fun to see
what the various LLVM passes do to the generated code.
It seems like there's been some work done on Rust for Z80 (and 6502):
