• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description holger-gentoo 2003-08-29 08:03:23 UTC]

Hi, 
 
this patch was created on the nove hrady kde hackfest. it speeds up the linking of cpp 
files a lot. 
i tested it with the actual binutils. i had a complete build of kdelibs, then i touched 
kdecore/kwin.cpp. 
then i did a time make with the old binutils, and this was the result (pentium 2ghz, 512 
mb ram) : 
 
 
real    3m8.135s 
user    2m43.230s 
sys     0m20.620s 
 
then i installed binutils with the patch applied and did the same again, result: 
 
real    1m11.000s 
user    0m44.550s 
sys     0m20.250s 
 
enjoy, Holger

maybe put this upstream too ?

Its non-trival to port to .6, which is currently our testing grounds - is there
a patch against .5 or .6 yet ?

Patch against 2.14.90.0.6

This patch applies cleanly against 2.14.90.0.6 - I've verified that it works
from stage1 all the way through emerge system, with no problems, as of this
morning.

Ah, cool.  I did look at trying to port it, but things changed a bit too
much to make it a Sunday afternoon job =)  Chris, who is the original author,
and know if it was submited to H.J. Lu or binutils yet ?
