IDA Pro指令追踪（Instruction tracing）

 Action name:ToggleTraceInstructions

 This command starts instruction tracing.You can then use all the debugger commands as usual:the debugger will save all the modified register values for each instruction.

 When you click on an instruction trace event in the'Tracing'window,IDA displays the corresponding register values preceding the execution of this instruction.In the'Result'column of the Tracing window,you can also see which registers were modified by this instruction.By using this information,you can for example quickly determine which instruction modified a specific register,or you can even backtrace the execution flow.Note that the IP register is never printed in the'Result'column,although it is usually modified by almost any instruction(except perhaps some prefixed instructions like REP MOVSB,...).

 Internally,the debugger runs the current thread step by step to properly obtain all the required register values.This explains why instruction tracing is slower than a normal execution.

以下为中文翻译：

 操作名称：ToggleTraceInstructions

 此命令启动指令跟踪。

 然后您可以像往常一样使用所有调试器命令：调试器将保存所有

 为每条指令修改寄存器值。

 当您在“跟踪”窗口中单击指令跟踪事件时，

 执行之前显示相应的寄存器值

 这条指令。在“跟踪”窗口的“结果”列中，您

 也可以看到哪些寄存器被这条指令修改了。

 通过使用此信息，您可以快速确定哪条指令

 修改特定的寄存器，或者您甚至可以回溯执行流程。

 请注意，IP寄存器永远不会打印在“结果”列中，尽管它通常是

 几乎被任何指令修改（除了一些前缀指令，如REP MOVSB，...）。

 步步运行当前线程

 正确获取所有必需的寄存器值。

 这解释了为什么指令跟踪比正常执行慢。
