; This file comes from rustc output, with the input program
; pub enum E { A, B }
; impl E {
; pub fn f(&self) {}
; }
; compiled with `rustc --crate-type=lib a.rs --emit llvm-ir -g` and
; copying the resulting `a.ll` file to here. This was done with rustc
; at nightly from 2021-09-28 (git 8f8092cc3), but rustc 1.57 should
; produce similar or identical output.
