S2E does not currently support under constrained symbolic
execution as implemented in UC-KLEE. There are quite a few
challenges to implement it:
- Unlike KLEE, S2E does not have any type information about the
program, this is a problem for lazy input initialization. You will
have to think about how to do it for binaries, perhaps with the
help of debug information if available.
- S2E runs by default an entire VM, which makes it awkward to run individual functions in isolation. That's fairly simple to solve though, e.g., with PyKVM  , which allows you to run small bits of binary code without any OS.
If you have source code available, it makes more sense to use
UC-KLEE than S2E in my opinion. More details about your project
would be needed to make a proper choice.
Hi all, I wonder if s2e supports under constrained symbolic execution - similar to UC-KLEE. If not, any place suggested to be modified? --
