Thanks Cristian for this information. Klee reply will not work in my case
because
I have to replay the test case with path files only.

[klee-dev] Error while replaying .path file

Dear all,
I want to replay a path file, but I am getting an assertion violation "hit
an invalid branch in replay path mode".
This is my toy program
*int main(int argc, char *argv[]){ if (argc != 2){printf("error:");
} int a; FILE *fp = fopen(argv[1], "r"); fscanf(fp,"%d",); if (a ==
10)assert(0); fclose(fp); return 0;}*
I run klee "*klee --libc=uclibc --posix-runtime --write-paths file.bc
--sym-arg 1 --sym-files 1 5*".
It finds an assertion violation (at test case number 19) and when I
replayed it by command
*klee --libc=uclibc --posix-runtime
--replay-path=klee-out-0/test19.path file.bc*
Klee crashes on assertion violation in Executor.cpp
What is the issue? It will be very helpful.

Thanking You

[klee-dev] Running SPEC benchmarks with klee
*** This email originates from outside Imperial. Do not click on links and attachments unless you recognise the sender. If you trust the sender, add them to your safe senders list https://spam.ic.ac.uk/SpamConsole/Senders.aspx to disable email stamping for this address. *** Dear all, I tried to run SPEC benchmarks with klee but I found that they require highly formatted input. Is there any way to handle these situations? Does anyone have previously rewritten the parsing code of SPEC benchmarks with insertion of klee_assume for removing useless execution. Any other different way to tackle this situation is welcomed. -- Thanks and Regards Awanish Pandey PhD, CSE IIT Kanpur ___ klee-dev mailing list klee-dev@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/klee-dev
[klee-dev] Replay ktestfile directory
Hi, I run klee over the coreutils using the command mentioned in coreutils experiments. When I replay the using -replay-ktest-dir="---" it is giving warning "KLEE: WARNING ONCE: replay did not consume all objects in test input. " Out of 156 test cases in ptx replay was able to run only 6 test cases. What is the problem or I am doing something wrong -- Thanking You Awanish Pandey PhD, CSE IIT Kanpur ___ klee-dev mailing list klee-dev@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/klee-dev
[klee-dev] Running latest coreutils with klee build on llvm3.4
Hi everyone, I used wllvm and it works. But it creates binary then extract-bc provide us bitcode. If I am adding klee_make_symbolic() in coreutils source code wllvm can't produce binary so unable to generate bitcode file. Is there any way to generate bc file for coreutils which contain klee_make_symbolic from llvm3.4 version? -- Thanking You Awanish Pandey PhD, CSE IIT Kanpur ___ klee-dev mailing list klee-dev@imperial.ac.uk https://mailman.ic.ac.uk/mailman/listinfo/klee-dev
