Actually I have two use cases.

1. Create a jump table and insert it to the binary and make the each function epilog instrumentation jump to it.

2. Introduce a new function which does some initialization and inject a call to it after the function main prolog.

Does it look doable?

Thanks

Hi,

Yes, you can add new functions. But depending on what exactly you want to do with the added function, there are different ways to do it.

For example, do you want to call this new function in your instrumentation? Do you want to add a new interface into a shared library?ÂÂ

Let me know the details so that we can find the best way to do it.

Thanks,

Hi All,

Is it possible to add new function to the binary using Dyninst APIs?

Cheers
