DynamoRIO
About DynamoRIO
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/AArch64
instruction manipulation library. DynamoRIO provides efficient,
transparent, and comprehensive manipulation of unmodified applications
running on stock operating systems (Windows, Linux, or Android) and commodity
IA-32, AMD64, ARM, and AArch64 hardware. Mac OSX support is in progress.
Existing DynamoRIO-based tools
Tools built on DynamoRIO and provided in our release package include:
- The memory debugging tool Dr. Memory
- The multi-process cache simulator and memory address trace collection and
analysis platform drcachesim - The legacy processor emulator
drcpusim - The "strace for Windows" tool drstrace
- The code coverage tool drcov
- The library tracing tool drltrace
- The disassembly tool drdisas
- The memory tracing tool memtrace
- The basic block tracing tool bbbuf
- The instruction counting tool inscount
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.
Downloading DynamoRIO
DynamoRIO is available free of charge as a binary package for both Windows
and Linux.
