Bindiffing with r2
==================
Graph diffing:
--------------
To find functions that are different from one to another binary:
radiff2 -C a b -> show report of all analyzed functions and say if they match or not
# get graphs with colorized basic blocks of unmatching function 0x8034804
radiff2 -g 0x8034804 a b > a.dot
radiff2 -g 0x8034804 b a > b.dot
xdot a.dot & xdot b.dot
TODO: loading information from previous analysis
Byte diffing:
-------------
radiff2 /bin/true /bin/false
Delta byte diffing:
-------------------
radiff2 -d /bin/true /bin/false
TODO: explain more modes and examples here...
