Debugging is a very time consuming task which is not well supported by existing tools. The existing methods do not provide tools enabling optimal developers' productivity when debugging regressions in complex systems. In this paper we describe a possible solution aiding differential debugging. The differential debugging technique performs analysis...

... a single terminal window. The output while debugging is situated in a side-by-side split window area called panes. Using an additional controller pane enables the developer to execute debugger commands in both the debugger panes simultaneously and display comparison data in additional helper panes if requested by issuing a user defined command. Fig. 2 illustrates the terminal-based user interface. The example is trivial -we have two versions of the same program where the initialization of the local variable var1 and var2 is inverted. The top pane is the controller pane and takes input from the programmer. The input is multiplexed simultaneously to the two instances of lldb loaded in ...

... Fig. 2 is easy to notice that the comparisons are done on syntactic level and contain some irrelevant information. Our system implements a configuration system that allows developers to specify regular expressions to filter out such syntax meaningless (for the particular debugging use case) ...
