Hi,

Seems like this is not a technical discussion anyway I did some
expiriments on my Fedora Core release 5 (Bordeaux)  PentiumIII
machine. Additionally to HARMONY-3246 it required a few modifications
in sources and proper arguments to the compiler to run HelloWord and
other applications. I can provide a patch with modifications to
building system to build PentiumIII friendly VM. Is anyone intrested
in this?

I would like to see these modifications. I wonder what you've done in port/src/thread/linux/apr_thread_ext.c and vmcore/include/atomics.h. They contain mfence and sfence instructions in inline assembly which have to be changed to something else on P3.

Fortunately we don't have to follow outcomes of those discussions
when we work in Harmony :)

Still we can ask the teams you referred to provide their feedback (if possible)
to a wider audience

As for the platforms some time ago Stepan said (and many people agreed to him)
that most of the things that we currently fix are OS-independent, so
we can focus
on 32-bit architecture and not tie ourselves much to a specific platform

Thanks,
Mikhail
