This is the x86/x64 plugin that ships with Binary Ninja.

Building the architecture plugin requires cmake 3.13 or above. You will also need the
Binary Ninja API source.
Run cmake. This can be done either from a separate build directory or from the source
directory. Once that is complete, run make in the build directory to compile the plugin.
The plugin can be found in the root of the build directory as libarch_x86.so,
libarch_x86.dylib or arch_x86.dll depending on your platform.
To install the plugin, first launch Binary Ninja and uncheck the "x86 architecture plugin" option in the "Core Plugins" section. This will cause Binary Ninja to stop loading the bundled plugin so that its replacement can be loaded. Once this is complete, you can copy the plugin into the user plugins directory (you can locate this by using the "Open Plugin Folder" option in the Binary Ninja UI).
Do not replace the architecture plugin in the Binary Ninja install directory. This will be overwritten every time there is a Binary Ninja update. Use the above process to ensure that updates do not automatically uninstall your custom build.
