Re: GDB record patch 0.1.3.1 for GDB-6.8 release
I think the good way is let user choice. When the user goes back a few
insns and he want to change the values of memory or register. The GDB
willtalk clear what will happen such as the future record will
destory, and ask user if he want to continue or not.
Then user can choice with himself.
How do you think?
