Re: [DynInst_API:] Control Flow Graph example with parseAPI

[Buddhika Chamith Kahawitage Don <budkahaw@xxxxxxxxxxxx>]

Hi,

Thanks for the pointers Thomas and Bill. Is there similar full source code example for the DataFlow API as well? I am specially interested in backward slicing for indirect jump target resolution example.

Regards

Buddhika

Also, the parseAPI example code exists as separate source files in parseAPI/doc, and is incorporated into the manual at build time. It could stand to get separated out as its own executable target, though.

Hey there,

not sure if this helps, but there is a fair bit of code that uses the ParseAPI and CFGs here:
https://github.com/google/functionsimsearch

In particular https://github.com/google/functionsimsearch/blob/master/dotgraphs.cpp dumps out
CFGs from an executable (ELF or PE) to .dot format for easy plotting.


Hope this helps,
Cheers,
Thomas

Sorry for the late response on this. Got side tracked with other pursuits. Anyways it would be just easier if these examples were in the form of executable tests/ examples within the Dyninst repository. Didn't see something like that though. Did I miss it? (I laboriously copied stuff from the pdf to assemble the example source. There is a chance I may have missed some stuff during that process)

Thanks
Buddhika

Hi Buddhika,

I have not encountered such issue before. If you still have this problem, you can send me you source file and ELF binary, and I will try to reproduce your issue and see what is happening.

Thanks,

Hi All,

I was trying to run control flow graph example (3.2) in the parseAPI documentation. When I run on some ELF binary I am getting lot of non ascii (binary) outputs instead of the intended output. Anyone come across this before?

Thanks
Buddhika
