; PR23216: We can't inline functions using llvm.localescape.

declare i8* @llvm.localrecover(i8*, i8*, i32)

define internal void @foo(i8* %fp) {
  %a.i8 = call i8* @llvm.localrecover(i8* bitcast (i32 ()* @bar to i8*), i8* %fp, i32 0)
  %a = bitcast i8* %a.i8 to i32*
  store i32 42, i32* %a

  tail call void @foo(i8* %fp)
  %r = load i32, i32* %a
  ret i32 %r

; We even bail when someone marks it alwaysinline.
