指令中弹出了多少字节:

   popf

? Oracle 的文档指出,应该通过在指令末尾附加 w 或 l 来将大小指定为单词或 long,但我正在查看的反汇编中不存在此类字母。

最佳答案

POPF/POPFD pops the word or doubleword on the top of the stack and stores the value in the flags register. If the operand-size attribute of the instruction is 16 bits, then a word is popped and the value is stored in FLAGS. If the operand-size attribute is 32 bits, then a doubleword is popped and the value is stored in EFLAGS.
