Just remember, using a red R in Slackware gives you better acceleration,
but using a yellow R increases your top speed.

Hi lmello,

Leave a post here: https://aur.archlinux.org/packages/gpodder3/ 
indicating your interest in maintaining gpodder3 for arch and I will 
disown the package as soon after so that you can then adopt it.

Re: [Slackbuilds-users] Desmume on 64-bit - optimization flag

[Matteo Bernardini]

A small thought: the problem setting ARCH=native is that the final package
will be called something like foo-1.1-native-1_SBo, while it should have a
name dependant on the minimum CPU where it will run (like Stuart is doing
on arm).

To get the CFLAGS selected by -march=native, for a possible use like
XGizzmo suggest, I use here this dirty trick

$ gcc -### -e -v -march=native /usr/include/stdlib.h 2>&1 | tail -1 | sed
"s|.*\"-march=|\"-march=|" | sed "s|\ -quiet\ .*||"
"-march=corei7-avx" -mcx16 -msahf -mno-movbe -mno-aes -mpclmul -mpopcnt
-mno-abm -mno-lwp -mno-fma -mno-fma4 -mno-xop -mno-bmi -mno-bmi2 -mno-tbm
-mavx -mno-avx2 -msse4.2 -msse4.1 -mno-lzcnt -mno-rdrnd -mno-f16c
-mno-fsgsbase --param "l1-cache-size=32" --param "l1-cache-line-size=64"
--param "l2-cache-size=3072" "-mtune=corei7-avx"

In theory, the resulting package built specifying these CFLAGS should be
called foo-1.1-corei7_avx-1_SBo (note the use of underscore in the ARCH to
avoid confusing pkgtool).

oh, I like this idea a lot - a huge usability win to not have to edit 
the .SlackBuild for such cases. of course, since SBo's official stance 
is "no support for multilib", I guess there's not much chance of this 
being acceptable... but it would be nice. also, probably want grep -q :)

the over-simplified answer is that it makes dynamic linking on x86_64 
possible, and that on x86 dynamic linking Just Works. if you'd like a 
more technical understanding, there are plenty of these available 
online, just google for something like "fpic x86_64" or "fpic amd64" or 
such.

Hi Cris!

I'm actually using BOTH... arch on a notebook and slackware on a 
desktop. I need two computers to 'train' my IT skills. And I just 
lve GNOME 3 - arch is the only distribution which ships GNOME 3 and 
*doesn't* split libraries and headers on their packages (who was the 
fucktard who had this 'genious' idea anyway?!) like slackware so it was 
really an obvious choice...


Do you think my gpodder SBo is better somewhat? Do as thou wilt, after 
all, 'when there's no copyright notices on a slackbuild it is assumed to 
be in the public domain', did I get it right? :)


Oh I see... you mean 'responsibility' for maintain the script, right? Oh 
well, I've never seen a 'missing' AUR of any software I actually use, 
it'd be an honor to contribute to the arch community somehow.


Oh wait it was you who asked me about the 2.x gpodder series! You know 
what? Dump that and merge gpodder to gpodder3. I guess nobody will 
complain...

i think you would have difficulties creating 32bit packages from 
64bit (multilib) slackware, as uname -m would set libdirsuffix to 64 
which is not what you want for 32bit package. you might have to add a  
&& ![ "$ARCH" = "i486" ] or something similar after the first part of 
the test.


thank for spotting it, you mean something like this?



it does not apply, because ARCH should not get changed in order to 
compile 32bit packages on multilib x86_64 bit systems, per 
http://www.slackware.com/~alien/multilib/ :


--
You will be able to use standard SlackBuilds to build 32-bit packages 
for

Slackware64.  There are two things to keep in mind:
(1) You will have to define the ARCH variable as 'x86_64' even though 
you

are compiling a 32-bit program!
(2) You will have to edit the SlackBuild and if it wants to use 
'lib64/'
directories for "$ARCH = x86_64", you will have to force it to use 
'lib/'
directories instead.  Usually, this is accomplished by finding a 
definition

like:
  LIBDIRSUFFIX="64"
and change this line to
  LIBDIRSUFFIX=""
--

so this is not even a consideration.

Well, one problem is that you have a package that advertises itself as
working on $ARCH (by having $ARCH in the package filename) but it may
not actually work on every CPU with that $ARCH so you can't safely
distribute it.

If you're going to go that route, why not just use -march=native?
Maybe also set $ARCH to "native" for lack of anything better to use,
and then it should be clear that you shouldn't redistribute the
resulting package.  I'm sure there's a way to work that into the 'if [
"$ARCH" = "i486" ] ...' stanza if you can find a way to add -fPIC and
set $LIBDIRSUFFIX appropriately on 64-bit machines.

still playing, this is what I came up with at the end

SLKCFLAGS=${SLKCFLAGS:--O2}
LIBDIRSUFFIX=""
[ "$(uname -m)" = "x86_64" ] && SLKCFLAGS="$SLKCFLAGS -fPIC"
LIBDIRSUFFIX="64"
[ "$ARCH" = "i?86" ] || [ "$ARCH" = "native" ] && SLKCFLAGS="$SLKCFLAGS
-march=$ARCH"
[ "$ARCH" = "i686" ] && SLKCFLAGS="$SLKCFLAGS -mtune=$ARCH"

I played a little with it

SLKCFLAGS=${SLKCFLAGS:--O2}
LIBDIRSUFFIX=""
[ "$ARCH" = "x86_64" ] || [ "$ARCH" = "native" -a "$(uname -m)" = "x86_64"
] \

Here's my first attempt at $ARCH=native:

SLKCFLAGS="-O2"
LIBDIRSUFFIX=""
if [ "$ARCH" = "x86_64" -o \( "$ARCH" = "native" -a "$(uname -m)" =
"x86_64" \) ]; then
  SLKCFLAGS="$SLKCFLAGS -fPIC"
  LIBDIRSUFFIX="64"
fi
if [ "$ARCH" = "native" ]; then
  SLKCFLAGS="$SLKCFLAGS -march=native"
elif [ "$ARCH" = "i486" ]; then
  SLKCFLAGS="$SLKCFLAGS -march=i486 -mtune=i686"
elif [ "$ARCH" = "i686" ]; then
  SLKCFLAGS="$SLKCFLAGS -march=i686 -mtune=i686"
fi

It indeed works, just tested it.

This could be useful not only for Desmume, but all 'heavyweight' 
computing applications such as Octave.


What do you guys think?

The correct 'if' statement would be:

if grep ssse3 /proc/cpuinfo 1> /dev/null; then
  SLKCFLAGS="$SLKCFLAGS -msse3"
fi

Re: [Slackbuilds-users] Desmume on 64-bit - optimization flag

Could just add an if statement that will add it to the SLKCFLAGS if it is
detected on the computer.

if grep [^s]sse3 /proc/cpuinfo 2>/dev/null; then
  SLKCFLAGS="$SLKCFLAGS -msse3"
fi

Not sure if this leads to undesirable results.  I don't have an sse3

Not all x86_64 CPUs support SSE3 (the lowest common denominator is SSE2),
so
adding this option by default will render the script unusable for owners of

[Slackbuilds-users] Desmume on 64-bit - optimization flag

Hi,

I've noticed that adding '-msse3' to the $SLKCFLAGS on a x86_64 bit 
build improves performance.
