new ARAnyM with better FPU

new ARAnyM with better FPU

[Petr Stehlik]

Hello there,

I think you might be interested in the new ARAnyM release. The version
0.9.12 comes with a brand new FPU emulation core that should be precise
because it's using the libmpfr, thanks to Andreas.

Andreas also fixed CAS and CAS2 instructions that were behaving
incorrectly in some cases.

Both these fixes could help running the Linux-m68k kernel and the
Debian-68k system more stable on the ARAnyM.

I have prepared some binary packages (available for download now) and
ARAnyM Debian maintainer is working on updating the package in Debian
sid as well.

Enjoy,

Petr

Well, beware: Ubuntu < 10.10 (including the 10.04 LTS Lucid Lynx) does
not have the necessary libmpfr3+. That also means that the Ubuntu Lucid
packages I have prepared at 

http://sourceforge.net/projects/aranym/files/aranym/0.9.12/

do NOT contain the new MPFR based FPU core made by Andreas.

So if you really want to try out the new ARAnyM FPU on your Hardy make
sure you'll backport libmpfr3+ there first.

Thanks!

I've just installed the binary for Lucid, and now cp/mv/du from coreutils
work again (they failed with out-of-memory errors under Ubuntu's 0.9.9).
I guess that was due to the CAS/CAS2 bugs?

Most probably.

I am wondering if it is worth backporting the libmpfr and making new
ARAnyM packages for 10.04 when the 12.04 is to be released in a month.

Indeed, next month we'll all be forced into the new GUI generation...

Actually we won't be forced into that. First, the 10.04 LTS is supported
till April next year so people can stay on it for another year. That's
why I was wondering whether to backport the libmpfr or not.

And second, we have several possibilities of not getting United :-)
There's the Classic mode of Gnome Shell that is basically good old Gnome
2 (just rewritten to use newer libraries), then the new Gnome Shell with
some particular extensions can be used almost like a normal desktop
(Linus and other reported) and at last but not least, the
http://cinnamon.linuxmint.com/ is maturing quickly!

Uhm guys – use Debian?

There’s also things like IceWM, evilwm and others. No need to go all GUI
on us poor unsuspecting textmode people.

But thanks for the reminder about mpfr. Will do that. Or try to push and
accelerate my move from hardy to testing.

I couldn't stand the feeling that Geert cannot enjoy new Andreas' MPFR
FPU emulation in ARAnyM so I have backported the libmpfr4 for Lucid:

http://sourceforge.net/projects/aranym/files/aranym/0.9.13/lucid_mpfr4/

And I have also released a new version of ARAnyM that includes another
fix that Andreas made two days ago:

http://sourceforge.net/projects/aranym/files/aranym/0.9.13/

Enjoy :-)

I’ve built mpfr4 for hardy and am now fighting with the PPA.
Should be there soon. I renamed the -dev package into libmpfr4-dev
to have this not be picked up by ANYTHING else in the system.

Mh. I’ll backport the src:aranym from sid once its maintainer (Cc’d)
has made the upload. Will post here then. (In the hope it doesn’t
use too many “new Debian” features…)

My other hosts use lenny (let’s just keep that alone, or maybe
I take my hardy source packages) and sid (so no issue once
Antonin has uploaded).

Since this lucid thing-y seems to get some use… here you are:
a forwardport of a backport of the official Debian sid mpfr4
and aranym packages ;-)

(just the stuff I backported to hardy, rebuilt for lucid)

Bad news:

aranym_0.9.12-1.lucid_amd64.deb: du works
aranym_0.9.13-1.lucid.mpfr4_amd64.deb: du fails with "memory exhausted",
just like in 0.9.9.

Hmm. The difference between those two particular packages is that the
latter has the new MPFR FPU that should have been better than the one in
previous versions (otherwise Andreas wouldn't bother implementing it, I
believe).

Could you please try building the http://packages.debian.org/sid/aranym
that contains a patch for another post-release FPU bugfix? If that
doesn't help then feel free to stay with 0.9.12 as it contains the CPU
CAS fixes and also the proven FPU.

Andreas is reading this for sure so he might have a clue about the
failing 'du' with MPFR FPU emulation as well.

The fix is in aranym_0.9.13-1.1 packages (Debian and Ubuntu):

I’ve NMU’d the package in Debian so it’s finally working, and backported
that¹ to Kubuntu Hardy, using my² backported mpfr4 (co-installable, does
not touch anything else in the system, thus safe to use).
