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.

Just remember, using a red R in Slackware gives you better acceleration,

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.

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.

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

2013-01-23 Thread 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 21 | 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).

2013-01-22 Thread Larry Hajali 
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
capable processor, so I can't test.

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

Yes, that probably is correct.  But there wasn't good information on sse3
vs. ssse3 when I did a google search.

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

2013-01-22 Thread Luis Henrique Mello 

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?

 Not sure if this leads to undesirable results.  I don't have an sse3
 capable processor, so I can't test.

 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.

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

[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.
