Thanks for the link, we'll try to use those when we detect g++.

They are documented but not in a decent way:

Of course, I was just looking at at assembly output in compiler explorer and
then locally I didn't link the object. That's why it seemed to work.
Compiling and linking I get:
$ ./bin/aarch64-none-linux-gnu

GCC has a builtin already for getting fpsr already too:
__builtin_aarch64_get_fpsr
Which of course is not documented ...

Note the ACLE does not require "fpsr" to be supported either only
"o0:op1:CRn:CRm:op2" format is listed there ...
