`name` প্যারামিটারটি **এখনও আবশ্যিক** (নন-অপশনাল) কারণ এটির কোনো ডিফল্ট মান নেই। তবুও, `name` এর মান হিসেবে `None` গ্রহণযোগ্য:

```Python
say_hi(name=None)  # এটি কাজ করে, None বৈধ 🎉
```

and offsets match.
On 32-bit systems, the low and high 32 bits of a 64-bit value are distinguished by adding
a <code>_lo</code> or <code>_hi</code> suffix to the name, as in <code>arg_lo+0(FP)</code> or <code>arg_hi+4(FP)</code>.
If a Go prototype does not name its result, the expected assembly name is <code>ret</code>.

<p>
The <code>SP</code> pseudo-register is a virtual stack pointer

  ///   '\\' c: matches character c
  /// character-range:
  ///   c: matches character c (c != '\\', '-', ']')
  ///   '\\' c: matches character c
  ///   lo '-' hi: matches character c for lo <= c <= hi
  ///
  /// Implementations must allocate `entries` to hold all names that need to be
  /// returned and return the size of `entries`. Caller takes ownership of
  /// `entries` after the call.
