text: AbstractMany critical codebases are written
in C, and most of them use preprocessor directives to encode variability, effectively
encoding software product lines. These preprocessor directives, however, challenge
any static code analysis. SPLlift, a previously presented approach for analyzing
software product lines, is limited to Java programs that use a rather simple feature
encoding and to analysis problems with a finite and ideally small domain. Other
approaches that allow the analysis of real-world C software product lines use
special-purpose analyses, preventing the reuse of existing analysis infrastructures
and ignoring the progress made by the static analysis community. This work presents
VarAlyzer, a novel static analysis approach for software product
lines. VarAlyzer first transforms preprocessor constructs to
plain C while preserving their variability and semantics. It then solves any given
distributive analysis problem on transformed product lines in a variability-aware
manner. VarAlyzer ’s analysis results are annotated with feature
constraints that encode in which configurations each result holds. Our experiments
with 95 compilation units of OpenSSL show that applying VarAlyzer
enables one to conduct inter-procedural, flow-, field- and context-sensitive data-flow
analyses on entire product lines for the first time, outperforming the product-based
approach for highly-configurable systems.
