>> runs OK on real aarch64 hardware.
May I know which hardware you are talking about. Is there an aarch64 hardware
target available ?

Title:
Arm64 fails to run a binary which runs OK on real hardware
Status in QEMU:
New
Bug description:
Note this is using the not-yet-upstream aarch64 patches from:
https://github.com/susematz/qemu/tree/aarch64-1.6
---- ----
This binary:
http://oirase.annexia.org/tmp/test.gz
runs OK on real aarch64 hardware. It is a statically linked Linux
binary which (if successful) will print "hello, world" and exit
cleanly.
On qemu-arm64 userspace emulator it doesn't print anything and loops
forever using 100% CPU.
---- ----
The following section is only if you wish to compile this binary from
source, otherwise you can ignore it.
First compile OCaml from:
https://github.com/ocaml/ocaml
(note you have to compile it on aarch64 or in qemu, it's not possible
to cross-compile). You will have to apply the one-line patch from:
https://sympa.inria.fr/sympa/arc/caml-list/2013-12/msg00179.html
./configure
make -j1 world.opt
Then do:
echo 'print_endline "hello, world"' > test.ml
./boot/ocamlrun ./ocamlopt -I stdlib stdlib.cmxa test.ml -o test
./test
