I am curious if I can develop my own programming language to output Cranelift or LLVM IRs, then use it to make a simple OS from scratch?
Specifically, do the instruction sets of Cranelift/LLVM IRs contain OS-level IO instructions?
Thank you.

LLVM-IR must allow inline-asm, since clang can compile C sources that use inline asm, and I think that works even if you compile through a temporary file with LLVM-IR text. I don't know whether there are other ways to represent special instructions like x86 `invlpg` in LLVM-IR; I'd guess not. – Peter Cordes Dec 18 '22 at 06:56
