[Nick Desaulniers via Phabricator via llvm-commits]

nickdesaulniers added a comment.

Also, I just used `llvm-reduce` for the first time to get:

  ; ModuleID = 'quarantine.ll'
  source_filename = "quarantine.i"
  target datalayout = "e-m:e-i8:8:32-i16:16:32-i64:64-i128:128-n32:64-S128"
  target triple = "aarch64-unknown-linux-gnu"
  ; Function Attrs: nounwind
  define dso_local i32 @a() #0 {
  entry:
    ret void
  }
  
  attributes #0 = { nounwind "correctly-rounded-divide-sqrt-fp-math"="false" "disable-tail-calls"="false" "frame-pointer"="non-leaf" "less-precise-fpmad"="false" "min-legal-vector-width"="0" "no-infs-fp-math"="false" "no-jump-tables"="false" "no-nans-fp-math"="false" "no-signed-zeros-fp-math"="false" "no-trapping-math"="false" "patchable-function-entry"="0" "stack-protector-buffer-size"="8" "target-cpu"="generic" "target-features"="+neon" "unsafe-fp-math"="false" "use-soft-float"="false" }
  
  !llvm.module.flags = !{!0}
  
  !0 = !{i32 1, !"wchar_size", i32 4}
