Interprocedural Analysis
Domain: Static Analysis / Programming Languages
Overview
A skill for analyzing programs across function/procedure boundaries, enabling whole-program analysis.
Capabilities
- Build call graphs and interprocedural control flow
- Perform context-sensitive analysis
- Handle function pointers and virtual calls
- Implement summary-based analysis
- Solve interprocedural data flow equations
Techniques
- Call Graph Construction: Direct/indirect calls, virtual dispatch
- Context Sensitivity: Call strings, cloning approaches
- Summary Functions: Pre/post conditions for procedures
- Pointer Analysis: Alias analysis integration
- Whole-Program Analysis: Linking and incremental solving
Use Cases
- Security vulnerability detection
- Program verification
- Compiler optimization (inlining, constant propagation)
- Bug finding across module boundaries
