Re: [DynInst_API:] testsuite v10.0.0 release?

[Barton Miller]

Yes.  In the frenzy of getting 10.0 out, we didn't tag a version of the test 
suite.  We've been under-staffed, so missed that.

We'll fix that shortly.

I'm using the upstream testsuite sources but the reason I ask about a formal 
https://github.com/dyninst/testsuite/releases release is that the rpm framework 
likes to be able to point to upstream sources.  For example for the 9.3 
releases in dyninst.spec (the rpm specfile) uses:
 Source1: 
https://github.com/dyninst/testsuite/archive/v9.3.0/testsuite-9.3.0.tar.gz
So for dyninst 10 it would be convenient to have a testsuite-10.0.0.tar.gz 
equivalent.  Meanwhile I created a local one with git archive

Thanks Xiaozhu. I will check it out.

 Hi All,

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

 Cheers

Re: [DynInst_API:] testsuite v10.0.0 release?

[Knapp, Rashawn L]

I found the Dyninst 10.0.0 test suite here: 
https://github.com/dyninst/testsuite  and built it with  Dyninst v10.0.0 using 
similar semantics as  with v9.3.0.

Any plan to do a testsuite release that corresponds to dyninst 10.0.0 similar 
to dyninst testsuite v9.3.0 for dyninst 9.3.x?

Re: [DynInst_API:] Add a new function

[Xiaozhu Meng]

It looks like you can create your own instrumentation library and use
Dyninst to insert calls to the library into the mutatee. Dyninst will
properly create linking dependency for the mutatee against the
instrumentation library.

You can refer to our code coverage code example to see how to program in
this way:

You can definitely instrument the exits of each function to call a common
function. This common function can contain the jump table and resides in
your instrumentation library. However, Dyninst does not provide the
functionality of creating jump tables. So you will need to do your code
generation to create a jump table.

You can write the new function in c/c++ and then compile it into your
instrumentation library, and then use Dyninst to inject calls to it.
