The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.
“手搓经济”的快速发展是市场创新活力的体现，但这一新兴业态仍面临现实挑战。生成式AI降低开发门槛的同时，也使得复制产品的成本极低，市场上已开始出现同质化“僵尸应用”。同时，AI辅助下的创作成果如何界定与保护产权等问题，仍缺乏明确规则。个人开发者在运营、维权等方面能力相对薄弱，也令产品的持续发展基础不够稳固。

与上次购车类似，父亲此番购车的预算也在十万元左右。但走进第一家店后我就发现，如今十万级的电车早已今非昔比——独立悬挂、电动尾门、座椅通风，这都是2021年时很难在这个价位看到的配置。
