ExprGenAttr 场景：ClassName 带 sha1 前缀（940e5294667daf5a.ExprGenAttr），struct_sha1_map.get(带前缀名)=None → class_sha1 为空 → _HandleMethodCallLlvm 的 stub 查找路径（if not func and class_sha1）被整体跳过 → fail-fast "Undefined method 'get_attribute_ptr'"（尽管 stub.ll 第 24 行存在该 declare）。

- 带前缀类名：class_sha1 直接取前 16 位，FullMethodName 不再拼接（避免双前缀）
- 裸类名：保持原逻辑从 _struct_sha1_map 取 sha1
