[gentoo-dev] KDE speed - wow

[gentoo-dev] KDE speed - wow

[Sebastian Werner]

Hey,

i compiled a fresh kde 3 desktop and all I could say...

wow what a speed!!! Never dream about KDE could have this speed and eyecandynes.

I use gcc-3.0.4 with the following cflags:
-march=i686 -O3 -pipe -fforce-addr -funroll-loops -fomit-frame-pointer -frerun-cse-after-loop -frerun-loop-opt -malign-functions=4

the newest binutils (2.12.90.0.3) package with active combreloc 

and the default gentoo kernel with all it's speed enhancements... ;-)

A word of warning.  The -funroll-loops optimization CAN cause problems
with GCC 3.0.x.  I used to use all of the below optimizations myself,
until I found -funroll-loops was more trouble than its worth (I had
several programs I actively debugged, only to find it was an
optimization error, and removing that particular optimization fixed the
problem -- the code itself looked fine).

Just a friendly note.  I dont believe theres a problem with
-funroll-loops on gcc 2.95.x.

hello,

	What packages did you rebuild apart from binutils ? I tried bootstrapping 
with gcc 3.0.4 but it died on ncurses.

cheers,
rich

No idea...

on packages which seems not compile lucky I use
only -O3 -march=i686 -pipe

for example
kdemultimedia-3 havbe a problem in /arts/tools
