It would be nice if 0 A.D. would support ARM64. There are Android
based devices on ARM64 already and I suspect we'll be seeing Linux
desktop devices based on ARM64 soon as well.
I know this is really an upstream issue, but it would be great if you
could raise an upstream feature request.
I briefly looked into it and created a patch with some obvious
locations where ARM64 (or AARCH64, as it's officially called) should
be added, but I'm sure it's incomplete. I also noticed
libraries/source/nvtt where ARM is referenced.
Note that I followed the existing code in source/lib/byte_order.h but
imho this is not an optimal way to do things as e.g. MIPS and ARM can
be both little or big endian.
