请教关于sigma studio编译输出提示疑问

这只是WARNING吧，且具体的意思只是说CYCLE数可能会有所变化。
至于这两个符号，就是序号，不用怕。
 
只要没有编译错误，就PASS。

那这变化会有多大，太大就会超出Inst(cycles) 吧？
具体如下所示：（”†“、”‡”被“？”替代了）
--------------------------------------------------------------------------------------

ExtDelay1                     26?       30        13      1       0 using: __MASTER_PORT_INIT__ using: __ISR_Write__ using: __ISR_Read__

我没有遇到过这样的现象，那就等出错再说吧。
