Is `rustc --opt-level 3 --emit ir` not right?

  The optimization level is given to LLVM. The IR itself should be the same for all optimization levels AFAIK.

    Almost all LLVM optimisations map IR to IR, and --emit=ir prints the final IR just before codegen (i.e. after optimisations happen).

      Oh? I was under the impression it was the IR that was given to LLVM to begin with. Interesting.
