Glad you tried the program and it works fine to you for the first place.
Dr. Swarup and John from UIUC wrote most of the code, and released the
original code to public. Dynamic slicing tool is really very useful.
Giri is now far from perfect. For example, there are know bugs for
multi-thread programs and I'm fixing it these weeks. I will take charge of
this project for a while and hopefully more people will join it. Dr. Swarup
and John will give us directions and suggestions (including coding reviews)
if we meet challenges. Dr. Swarup also suggested some works we should do
next. I shall maintain a TODO list in the wiki
page<https://github.com/liuml07/giri/wiki/TODO>of this project. Thus
you can pick up one and make improvements according
to your interest and schedule. The most obvious one is to make the code
work with latest LLVM 3.4.
To get to know how the slicing passes work, there are sever papers for your
- Differential Slicing: Identifying Causal Execution Differences for
- Dynamic Program Slicing
- Precise Dynamic Slicing Algorithms
- Using Likely Invariants for Automated Software Fault Localization
