dynamic-instrumentation

Dynamic binary instrumentation traces memory accesses in LLVM-based software by lifting code at runtime to insert analysis callbacks. This allows you to observe behavior and track memory without modifying the original source code.

LLVM-based runtime instrumentation is used for dynamic analysis tasks like profiling, tracing, and security monitoring. It instruments binaries at runtime to observe application behavior and collect execution data.

Yes, you can hook instrumentation callbacks for selective code range tracking. The tool supports address callbacks to selectively instrument specific code ranges, enabling targeted runtime monitoring and data collection.

Dynamic binary instrumentation does not require source code to build a profiler. It instruments compiled binaries at runtime, enabling code coverage tools and runtime monitors for LLVM-based applications without source access.

The best way to monitor runtime behavior without recompiling is using LLVM-based DBI tooling. It lifts existing code, inserts analysis hooks, and tracks memory accesses dynamically during execution.

LLVM-based tooling for dynamic binary instrumentation integrates with frameworks like QBDI and Instrew to lift code and insert analysis. It provides robust memory access tracking and profiling for LLVM-based software environments.
