Top level intermodule profiledbootstrap, for people with too much free time.

I wrote this a few weeks ago...

# The following is a study of possible ways to optimize the GNU toolchain.
#
# First of all, I made the assumption that using the Top Level Makefile
# system, included with the recent GCC and Binutils versions, has a greater
# potential for optimizing the applications than building them each 
# separately. I also did not study non-bootstrapped builds because a 
# non-bootstrapped toolchain has no reason to perform better than a 
# bootstrapped toolchain.

# I performed this study with all the tricks I know of to optimize the
# toolchain, including intermodule builds, profiled builds, and GNU hash
# style.

# The top level makefile system also adds the potential of profiling a pile of
# other packages, like flex and bison and gettext and bash and findutils and
# much more. But I have yet to get that to work for me.

# The --enable-intermodule option will make GCC use the -combine option
# to compile all sources in the same command line. The idea is that the
# compiler can optimize all the sources together and make better judgments.
# This option should also take better advantage of the -O3 option. The only
# other package I know of that uses -combine (and also uses -fwhole-program)
# is Busybox, because it not only increases performance but also decreases
# program size (about 1%).

# My system is a Pentium 4 prescott, 3GHZ, with 1024MB of physical memory.
# Running kernel 2.6.19.2, and Glibc-2.5. This toolchain version's are the
# same versions on the chrooted host system (chapter 6 LFS). I have a 1024MB

Re: Top level intermodule profiledbootstrap, for people with too much free time.

Also, if you have a lot of memory, the Arts/KDE option '--enable-final' is a 
mimic of GCC's -combine, in that it combines all the .cpp files so they're 
optimized together. The './configure --help' says '--enable-final build size 
optimized apps', but this option does more for performance than for size. 
Also see:
http://developer.kde.org/documentation/other/developer-faq.html#q2.7
If you have enough memory to do this without using swap it will also make the 
build faster because of less disc activity.

Intel 3945ABG Wireless Chipset

Was just recently reading an article on kerneltrap.org about intel's
new wireless drivers, and was attempting to find out more information.

My first look through google only shown the chipset embedded into
laptop's, and I was wondering if anyone knew if they ever planned to
make a seperate addon PCI/PCMCIA/PCI Express card.

the option of other devices to use the chipsets in
such a device.

on a positive note, they do have open source linux
rivers for the chipset on
http://ipw3945.sourceforge.net [ development version.
this driver requires kernel 2.6.13 or newer to
function.

Old LFS Release package archives

Hello everybody,

     I'm back in the US and I'm on a mission. I'm archiving all old  
LFS Release package archives. If you have anything from 1.0 to 5.1.1  
please let me know. I want to archive them all. This is an important  
project .

Sincerely,

William Harrington

Hi William.  Go crazy over at 
http://archive.linuxfromscratch.org/lfs-museum/ :-)  Or is it the actual 
source tarballs you were after?  In which case, I can't help I'm afraid.

Matt.

I can find the books at the museum, but no one has archived the  
packages and patches, which is a shame.

Most of the packages I can grab from the source of old distros like  
slackware and redhat and gnu ftp servers keep older releases most of  
the time, however, it's the patches that is the problem.

So yes, the source tarballs with the source is needed. I'm archiving  
the current lfs-packages onto my array. I was wanting to build an LFS  
3.3 system for my 486 for fun times, but... the patches are kinda  
missing. Also, I have the 4.0 CDs here, but the patches aren't

Honestly, why would you want to build an ancient LFS? I understand the 
fun-part of it (I did that too) but nowadays I'm building minimal-LFSes 
using up to date 'embedded' packages (linux2.4, busybox, uclibc, ...).

Sorry for not being able to help you with your quest, but if you need 
more information about 'embedded' (in quotes because it's not really 
embedded ;) packages, feel free to ask.

Regards,
Philipp

Website Building

I've been building a few websites with Joomla! and Typo3, as well as
with the old HTML+CSS static method.  I need to build one for the
church, and they say they can't afford an SQL database, so I'm looking
for ideas.  PHP4 is included in their free hosting package, but I'm not
up to writing a whole CMS from scratch.

I'm concerned that a static site will end up with me changing it every
day and it will turn into a support nightmare.

Any suggestions?

R.
