Oxc CFG

Control Flow Graph construction and analysis for JavaScript and TypeScript.

Overview

This crate provides data structures and algorithms for building and analyzing Control Flow Graphs (CFGs) from AST nodes. CFGs are essential for advanced static analysis, optimization, and understanding program flow.

Key Features

CFG construction: Build control flow graphs from AST nodes
Block-based representation: Organizes code into basic blocks
Graph analysis: Traverse and analyze control flow patterns
DOT export: Visualize CFGs using Graphviz dot format
Visitor integration: Works with oxc visitor patterns

Architecture

Basic Blocks

The CFG organizes code into basic blocks - sequences of instructions with:

Single entry point (first instruction)
Single exit point (last instruction)
No internal branches or jumps

Graph Structure

Nodes: Basic blocks containing instructions
Edges: Control flow between blocks (conditional, unconditional, exception)
Entry/Exit: Special blocks for function entry and exit points

Analysis Applications

Dead code elimination: Find unreachable blocks
Data flow analysis: Track variable usage across control paths
Loop detection: Identify back edges and loop structures
Path analysis: Enumerate possible execution paths

The CFG integrates with semantic analysis to provide comprehensive program understanding.
