DynamoRIO is a runtime code manipulation system that supports code transformations on any part of a program, while it executes. DynamoRIO gives complete control over the runtime code stream and does not limit transformations to trampoline insertion. DynamoRIO exports an interface for building dynamic tools for a wide variety of uses: program analysis and understanding, profiling, instrumentation, optimization, translation, etc. DynamoRIO provides efficient, transparent, and comprehensive manipulation of an unmodified application running on a stock operating system (Windows, Linux, or Android) and commodity IA-32, AMD64, ARM, and AArch64 hardware. See Platform Limitations for details of which platform combinations are fully supported.

This document describes the DynamoRIO system and the various API's that it exports for building custom tools. It is divided into the following sections:

Deployment
How to run DynamoRIO.
Usage Model for DynamoRIO
How to make use of DynamoRIO.
Code Manipulation API
DynamoRIO's full runtime code manipulation interface.
IA-32/AMD64/ARM/AArch64 Disassembly Library
DynamoRIO can be used as a standalone library for IA-32/AMD64/ARM/AArch64 disassembly, decoding, encoding, and general instruction manipulation. A separate static library is provided for this purpose.
API Usage Tutorial
Gives a few short tutorials on using DynamoRIO.
Sample Use Cases
Shows some sample use cases and reference implementations.
DynamoRIO-Based Tools
A collection of powerful DynamoRIO-based tools are provided for direct use, including our Cache Simulator and memory access trace collection and analysis platform, the Dr. Memory Memory Debugging Tool, our Code Coverage Tool, and more.
