Hello everyone,
I am trying to use the taint analysis from the following project:
http://cs.famaf.unc.edu.ar/~rcorin/kleecrypto/ . They have a KLEE program
that is doing taint analysis, it is in the examples folder.
I receive the following KLEE error : *failed external call:
klee_set_pc_taint*.
Hi,
If you search the PATCH OF KLEE
http://keeda.stanford.edu/pipermail/klee-dev/attachments/20121007/6b3c595b/attachment-0001.obj
for:
add(klee_set_taint
...you will see that it is handled in
klee/lib/Core/SpecialFunctionHandler.cpp.
Thanks,
Paul

I'm not sure your patch is applying cleanly there but the bigger

hence nothing can be built.
Take a look at config.log (generated when running configure in the
KLEE directory) for hints about what went wrong but it looks like
Yes, that's why I was afraid for, the patch breaking the build. thank you a
lot for the detailed information !
I will try and hope it works

Hi,
I need to understand how to use klee_assume and klee_assert.
I tried to implement the following assumptions (in the function listed below)
which assumed that if a symbolic variable x satisfies the condition !(0(x+5))
and that if another variable y is set to x+7, I want to check whether y is
Thanks Daniel,
This is very helpful.
So, my next question is how does klee generate such a condition based on the
following set of commands?!
klee_assume(!(0(x+5)));
klee_assume(y==x+7);
klee_assert(y0);
I would appreciate if you provide me with some guidance of how klee_assume and
