This project includes a build script and code samples used to verify various properties of the implementation of ARM MTE. See the blog post here for more information:

Note that most of these examples are written to demonstrate specific software or hardware behaviour observed on a single test device configuration, so you may encounter difficulties in reproducing the results in a different environment, and will need to provide your own configuration for the core layout of your test device, and likely also calibrate the timer and branch prediction iterations (see config.py and config.h).
