--- Comment #12 from sourceware at johnea dot net ---
Thank you Luis!

I'm glad to hear you have a patch in mind.

I'm currently working on actual hardware, a xilinx zcu102 dev board.

I'll try now in QEMU and report results.

And Yes, the 'hello' executable on the x86 host is aarch64.
file command executed on the x86 host:
$ file hello
hello: ELF 64-bit LSB pie executable, ARM aarch64, version 1 (SYSV),
dynamically linked, interpreter /lib/ld-linux-aarch64.so.1,
BuildID[sha1]=3D4ee6eadc116d54aff8c7e180f8622bbdfaad4ad6, for GNU/Linux 3.7=
.0,
with debug_info, not stripped

I built this on the aarch64 target, and copied the 'hello' executable to the
x86 host for access to symbols.
