Yes, when a function is inlined, the caller's context can dramatically affect optimizations. And inspecting varargs functions can be tricky. But beyond that, it generally displays exactly what gets executed. You can verify this yourself by looking at functions with different `-O` or `--inline=no` flags. And if you're interested how a function optimizes with inlining under typical conditions, you can just inspect the outer function.
