1. Immediate addressing - Make the common case fast
2. Register addressing - Simplicity favors regularity
3. Base or displacement - Make the common case fast
4. PC-relative addressing - Make the common case fast
5. Psuedodirect addressing - ??
请问一下为什麽1.2.4分别对应到这些基本设计原则?
还有第4个我解答有两种，另外一种是Make the common case fast
请问一个哪个答案比较恰当?
谢谢
