DynamoRIO Overview

DynamoRIO is a runtime code manipulation system that supports code transformations on any part of a program, while it executes. DynamoRIO exports an interface for building dynamic tools for a wide variety of uses: program analysis and understanding, profiling, instrumentation, optimization, translation, etc. Unlike many dynamic tool systems, DynamoRIO is not limited to insertion of callouts/trampolines and allows arbitrary modifications to application instructions via a powerful IA-32/AMD64/ARM instruction manipulation library. DynamoRIO provides efficient, transparent, and comprehensive manipulation of unmodified applications running on stock operating systems (Windows or Linux) and commodity IA-32, AMD64, and ARM hardware.

Existing DynamoRIO-based tools

Tools built on DynamoRIO include:

Building Your Own Custom Tools

DynamoRIO's powerful API abstracts away the details of the underlying infrastructure and allows the tool builder to concentrate on analyzing or modifying the application's runtime code stream. API documentation is included in the release package and can also be browsed online. Slides from our past tutorials are also available.


We will be holding a tutorial on DynamoRIO at CGO 2016.

Downloading DynamoRIO

DynamoRIO is available free of charge as a binary package for both Windows and Linux. DynamoRIO's source code is available under a BSD license.
