Hi,  guys: 

    I have a question about watch-point.
    If the program mapped a physical address(PA)  to two(or more than one) virtual address (VA and VB), if I set a watchpiont at Va, after this, I modify VB, what does gdb do? 
    Trigger a watchpoint or do nothing? If triggered a watchpoint how to report it?
    If anyone knows, pls help me with it. 
    
    Thinks a lot.
