================
Comment at: llvm/test/Transforms/InstCombine/printf-2.ll:76
+  %str = getelementptr [13 x i8], [13 x i8]* @hello_world, i32 0, i32 0
+  call void (i8*, ...) @printf(i8* %fmt, i8* %str)
+  ret void
----------------
This does't fire when `@printf` returns the status, and/or when that status is used, right?
