The command is "info registers", of "info r" for short. You can also print an individual register using (say) "print $rax" (prefix the register name by $) or "info r rax". If you're stepping, you can set up a *layout* that shows all the register values as you step along. You also might consider using a reverse debugging tool like the "undo" debugger. They track enough information to allow them to (effectively) execute backwards from a point. Not sure if any work under cygwin, though. By the way, I got the commands for printing individual registers with a simple web search :-) ...
