PrintIR

Module PrintIR

Outputs a representation of the IR as a control flow graph.

This file contains the actual implementation of PrintIR.ql. For test cases and very small databases, PrintIR.ql can be run directly to dump the IR for the entire database. For most uses, however, it is better to write a query that imports PrintIR.qll, extends PrintIRConfiguration, and overrides shouldPrintDeclaration() to select a subset of declarations to dump.

Imports

IRConfiguration

Module used to configure the IR generation process.

Predicates

edges	Holds if the output graph contains an edge from `pred` to `succ`, and that edge’s property `key` has the given `value`.
nodes	Holds if `node` belongs to the output graph, and its property `key` has the given `value`.
parents	Holds if `parent` is the parent node of `child` in the output graph.

Classes

PrintIRConfiguration

The query can extend this class to control which declarations are printed.
