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.
他近兩個小時的演說中,只零星提及少數想法,包括為美國勞工階層設立新的退休儲蓄帳戶,以及與AI公司達成協議,提供足夠電力給其工廠,以及避免消費者電費上漲。他還重新推銷一些舊有想法,例如提供直接補助幫助美國人支付醫療保險費用的計劃、要求所有選民證明公民身份的法律,以及禁止向非法移民發放商業駕照。
,这一点在搜狗输入法2026中也有详细论述
听闻一桩事:某人在网上对他人点名道姓批骂,之前还有所克制,后来见人没有回应,他胆子壮大了,连篇累牍,捏造事实,什么话伤人,就拣什么话来骂。没想到,人家一纸诉状给告了,某人便急了,急忙去求情,请人宽容:大人不记小人过。那模样,全然没有了当初网骂的嚣张气焰。
Part of a Soviet-era spacecraft is likely to have re-entered the Earth's atmosphere after being stuck in orbit for more than half a century, the European Space Agency said.
