Acovea-4.0.0 : Try out my ebuilds (and scripts)

I would like to say these are some pretty wild scripts. I have just run the scripts for about 26 hours now. Treebench.c got errors (*** glibc detected *** double free or corruption (fasttop): 0x0804e020 ***) so I just ^c out of it.

I got enough data though so that the cool perl script was able to do its deed. My question is now what do I do with it? I have read through this forum and am still quite confused.

I have the same prob, running Acovea.
The post is; https://forums.gentoo.org/viewtopic-t-343680-highlight-acovea.html

I was wondering if I could use the results as below anyway??. They nmight not be sooperreliable, but very useful nonetheless?.

From the above list of suggested Acovea CFLAGS, I use the following;

CFLAGS="-O2 -march=pentium4 -fno-crossjumping -fno-if-conversion2 -fprefetch-loop-arrays -minline-all-stringops -frename-registers -fno-delayed-branch -fno-omit-frame-pointer -finline-functions -maccumulate-outgoing-args -fno-thread-jumps -fmove-all-movables -mno-align-stringops -funroll-loops -fno-cprop-registers -funroll-all-loops -pipe -wall"

Have I deleted all dangerous flags there?.

Sorry if this is already covered somewhere in this thread, but reading 16 pages was a bit too much...

I have a Duron 1000, what config file should I use? The first posts in this thread (from 2004 though) say that noone was able to run the benchmark on an Athlon so far. And after emerging acovea I only had files for pentium and opteron. Is there any place to get configs for other CPUs like a Duron? Using -march=athlon-xp does work for me, so maybe I could also go with an Athlon XP file.

[bur]

Okay, so I edited the gcc3.3_opteron file. I used -march=athlon-xp and commented out all "specific to Intel-style architecture" and "fast-math" options. The tests do run without problems so far, though I don't have any results yet.

What I do wonder is, if there are specific intel options, are there specific amd options that I should insert in the config file?
