And the text hints at it, but the exact trick to figure out the
offsets to put in the "what" ELF section is to compile and link it
once, then run
$ llv
This might also help:

A working but not simple solution is to make a simple hello.c, and
compile it with --save-temps.
This means you get a hello.s in there too, and you can build that with
cc -O2 -pipe -o hello hello.s
and you have a working binary, with the correct ELF sections and everything.
It becomes some 5200

Hi guys!
Please, could someone tell me how to print a very simple "Hello, world!" in
assembly for aarch64?
Thanks for reply.
