One more task I need to complete is moving the code from **Orc/TargetProcess** to **Orc/Shared**, so that it can be used on the Root side as an API.

Also, before merging, can we make sure the unit tests are running correctly? Right now, they only work for Mach-O binaries. I created a fat binary (**x86\_64 + arm64 + arm64e**) YAML, where the x86\_64 and arm64e parts were cross-compiled, and I generated the YAML file. However, I’ve only tested it on **arm64**, not on **x86\_64**.
