Rose::BinaryAnalysis::Partitioner2::ModulesX86::FunctionReturnDetector Class Reference

Description

Basic block callback to detect function returns.

The architecture agnostic isFunctionReturn test for basic blocks does not detect x86 "RET N" (N!=0) instructions as returning from a function because such instructions have side effects that apply after the return-to address is popped from the stack. Therefore this basic block callback looks for such instructions and sets the isFunctionReturn property for the basic block.

Callback method.

This is the method invoked for the callback. The chain argument is the return value from the previous callback in the list (true for the first callback). The successor callbacks use chain to indicate whether subsequent callbacks should do anything.

Implements Rose::BinaryAnalysis::Partitioner2::BasicBlockCallback.
