os-cfi's Issues

Hello, I am a Chinese university student and I want to use your project.However, a problem occurred during the test using

First of all, I'm very sorry that I downloaded your project without contacting you. In my graduation project I want to generate the CFG of the program, so I would like to see your generated CFG. I use ubuntu22.04 to compile the project. But the sample_exec compiled after I run test_run.sh cannot run normally, and the error message is similar: [Unexpected trap 13! at 0x402908(core dumped). And the cpp program I tested also has this problem. May I ask what the possible question is?where does the CFG exist?Thank you so much!

About the specific SPEC CPU2006’s version? 

I am a postgraduate from a university in China and I am currently reproducing your thesis. However,  I encountered a problem that the number of indirect calls are not the same as your sheet in your paper.(**I am testing under SPEC CPU2006 v1.2**)
**Anyway, I would like to ask what is your specific version about the SPEC CPU2006? Hope to hear from you and wish you a happy life!**

No lib folder on step 9.

I have implemented the installation procedure from the beginning but I stuck on step 9. There is no lib folder on llvm-obj. What may be the problem? I think the step 6 was not shown completely. I am presenting your paper this Friday, so wanted to experiment the results.
