DynamoRIO is a runtime code manipulation system that supports arbitrary code transformations on executing programs, with a powerful instruction manipulation library for IA-32, AMD64, ARM, and AArch64. It serves as a platform for building dynamic tools such as profilers, fuzzers, memory debuggers, and cache simulators on unmodified applications.

Use cases

• instrument a program at runtime for profiling
• fuzz Windows binaries with code coverage feedback
• simulate CPU caches and TLBs from instruction traces
• trace memory addresses and function calls of an application
• detect memory errors in unmodified binaries
• analyze opcode mixes and reuse distances of a workload

When to choose

• you need fine-grained dynamic binary instrumentation on x86, ARM, or AArch64
• you want to build custom program analysis or profiling tools
• you need to instrument unmodified applications on Windows, Linux, or Android
• you need an instrumentation engine for a fuzzer like WinAFL

When to avoid

• you only need simple static analysis of binaries
• you want source-level instrumentation rather than binary-level
• you need macOS support, which is still in progress
• you need a lightweight sampling profiler without deep instrumentation
