- liklely 我在 lab0 中研讀 list_sort() 時學習到 likely 巨集使 copmpiler 優化程式碼, 可以有效增加 branch hit 的次數。 likely 的定義在 include/linux/compiler.h 中, 其實作如下 (若沒有開啟 branch profiling): #define likely(x) __builtin_expect(!!(x), 1) __builtin_expect 為 gcc built-in function, 其在 x 前加兩個 ! 得原因為若想判斷 x 為非 0 整數, 透過 !! (x) 可以確保出來的值是 1, 而達到判斷非 0 整數的目的。 較詳細的探討請參考我的 lab0 共筆 的 likely 部分。
