Currently FPC trunk can compile to "arm64" target for macOS.
In the final release of Big Sur Apple compiles own apps in "arm64e". You can check it using
lipo -archs /Applications/Safari.app/Contents/MacOS/Safari
It seems that arm64e is a new generation of arm64:
- Pointer authentication
- Nested virtualization
- Advanced SIMD complex number support
- Improved Javascript data type conversion support
- A change to the memory consistency model
- ID mechanism support for larger system-visible caches
Is it possible that "arm64" will be declared as deprecated in nearest future?
Can FPC compile to arm64e ?
