What is the gdb command to have the program run certain number of loops,
instead of using "n" command to do it line by line?

Say, if I have a loop that runs 1000 time and I want to see the variable
values at the 990th interval, what gdb command I should run to have the loop
stop at 990th?

Thanks!
