What does "aarch64" actually mean here?
Does it also cover 32bit-only aarch64 CPUs?

Similar to x86 there are 3 ABIs, and aarch64ilp32 is different from aarch32.

Different from x86, there is no ABI that is available in all aarch64 CPUs.
They can be 32bit-only or 64bit-only, and aarch32 support is optional.
