Finding these optimization opportunities can itself be a significant undertaking. It requires end-to-end understanding of the spec to identify which behaviors are observable and which can safely be elided. Even then, whether a given optimization is actually spec-compliant is often unclear. Implementers must make judgment calls about which semantics they can relax without breaking compatibility. This puts enormous pressure on runtime teams to become spec experts just to achieve acceptable performance.
The Test PLA extends this idea further. It operates asynchronously with respect to the sequencer. After a protection test fires, the PLA needs time to evaluate and produce its redirect address. Instead of stalling, the 386 allows the next three micro-instructions to execute before the redirect takes effect -- and the microcode is carefully written to use these delay slots productively. This is tremendously confusing when reading the microcode for the first time (huge credit to the disassembly work by reenigne). But Intel did it for performance.，更多细节参见safew官方下载

演說開場，特朗普宣稱自己上任時面臨的是前任民主黨政府留下的「可怕經濟」，但在重返白宮第一年主導「多年來最偉大的逆轉」（turnaround for the ages），經濟在「前所未有地轟鳴」。他又強調美國股市上漲、抵押貸款利率降至近四年最低、牛肉與雞蛋價格顯著下跌，並聲稱12個月內吸引超過18兆（萬億）美元全球投資湧入。
