I think it should be realy simple to implement, as i think kdevelop
dosn't realy know the direction it just gets next data after step or
continue.
I think without changing anything in kdevelop simply putting at gdb
console direction change it should work, if I understand below reference
manual properly but for convenience propably would be better to have a
new 'toggle direction' toolbar item.

http://www.gnu.org/software/gdb/news/reversible.html

"set exec-direction (forward/reverse) -- Set direction of execution.
All subsequent execution commands (continue, step, until etc.) will run
the program being debugged in the selected direction."

..anyway it is interesting, I didnt know that it is possible ...
