Title: 
A lightweight dataflow analysis to support source code reading

Abstract:
In software inspection process, a developer often has to inspect 
source code fragments in various modules without a deep knowledge 
on the code fragments.  While program slicing can extract dependence
relations in source code fragments to support code reading, slicing
sometimes takes a long time to analyze a large program.  
In this research, we propose a lightweight dataflow analysis; 
our key idea is an approximation of data-flow by expressions in 
AST without control-flow analysis.  We are implementing the approach 
as a tool to extract and visualize implicit data flow paths outside 
of a source code fragment so that developers effectively inspect 
the fragment.
