IDA Pro重命名寄存器 （Rename register）

Action name:RenameRegister

This command allows you to rename a processor general register to some meaningful name.While this is not used very often on IBM PCs,it is especially useful on RISC processors with lots of registers.

For example,a general register R9 is not very meaningful and a name like'CurrentTime'is much better.

This command can be used to define a new register name as well as to remove it.Just move the cursor on the register name and press enter.If you enter the new register name as an empty string,then the definition will be deleted.

If you have selected a range before using this command,then the definition will be restricted to the selected range.But in any case,the definition cannot cross the function boundaries.

You cannot use this command if the current instruction does not belong to any function.

操作名称：重命名寄存器

此命令允许您将处理器通用寄存器重命名为有意义的名称。虽然这在IBM PC上不常使用，但在具有大量寄存器的RISC处理器上尤其有用。

例如，通用寄存器R9不是很有意义，像“CurrentTime”这样的名称要好得多。

这个命令可以用来定义一个新的寄存器名称，也可以用来删除它。只需将光标移动到寄存器名称上，然后按enter键。如果你将新的寄存器名作为空字符串输入，那么定义将被删除。如果

你在使用这个命令之前选择了一个范围，则该定义将被限制在所选择的范围内。但在任何情况下，定义都不能跨越函数边界。

如果当前指令不属于任何函数，则不能使用此命令。
