The API of LLVMDependenceGraph is now... well, not nice. I'm working on better one. However, you need to get the right dependence graph and search for the instruction there: https://github.com/mchalupa/dg/blob/master/include/dg/llvm/LLVMDependenceGraph.h#L229...

No, the node identifier is the address of the node.

In what form you need the data dependence? If you are just viewing the dependecies via `llvm-dg-dump`, then there are these options: ``` Dot printer options: --call - Print calls...

> The results are really long, it seems that the tool doesn't only analyze function do_mount() but also a lot of other functions, is it normal? Yes, the analysis is...

Since there have been multiple needs for such a functionality in the past, I quickly hacked a tool that gives you only the data (or control) dependence for a given...

We can also add a new special memory location `argv`

Great! I very appreciate that :) Extractelement and insertelement are vector instructions that are used frequently in C++ IR. For basic C++ support, the instructions connected with exceptions are needed...

Hmm, maybe we should just invalidate post-dominators after slicing -- and compute new when needed

This commit should fix the problem with unsupported instruction: https://github.com/mchalupa/dg/commit/91297431115a8c75ca87e28bedcd386dd46e00ad, but that is not probably the problem that makes DG hang. As far as I can tell, DG does not...
