Pin is a dynamic binary instrumentation framework for the the IA-32 and x86-64 instruction-set architectures that enables the creation of dynamic program analysis tools. Some tools built with Pin are Intel® VTune™ Amplifier, Intel® Inspector, Intel® Advisor and Intel® Software Development Emulator (Intel® SDE). The tools created using Pin, called Pintools, can be used to perform program analysis on user space applications on Linux*, Windows* and macOS*. As a dynamic binary instrumentation tool, instrumentation is performed at run time on the compiled binary files. Thus, it requires no recompiling of source code and can support instrumenting programs that dynamically generate code.

Pin provides a rich API that abstracts away the underlying instruction-set idiosyncrasies and allows context information such as register contents to be passed to the injected code as parameters. Pin automatically saves and restores the registers that are overwritten by the injected code so the application continues to work. Limited access to symbol and debug information is available as well.

Pin was originally created as a tool for computer architecture analysis, but its flexible API and an active community (called "Pinheads") have created a diverse set of tools for security, emulation and parallel program analysis.


As of in Pin 3.26, Pin provides an additional Windows Kit with LLVM clang-cl based C++ runtime, supporting C++11 and large portions of C++ 17.

Using the LLVM C++ runtime requires Pin Tools to be built with LLVM clang-cl toolset instead of Microsoft MSVC toolset.

Detailed adoption instructions, as well as good practices, are provided in Pin CRT document available in User Documentation section and in Download page.

Examples included in the new kit were fully adopted to use clang-cl. In addition, a Visual Studio C++ project template is provided with MyPinTool example (source\tools\MyPinTool).

Existing MSVC based Pin Kit continues to support C++03 (only).
