Yes, we dropped it as it was much pain for very little optimizing improvements. Most of the time, these flags are supplied elsewhere by the compiler or the build system, so they are unnecessary.

Rob, did we drop the whole attempt at detecting the arch by now ?

According to this link:

https://www.x86-64.org/pipermail/bugs/2004-December/000862.html

"(SEMPRON is an AMD Athlon 64 with less L2 cache and without 64bit support)"

I am running the powernow-k8 module as a matter of fact.

Also, my make had stopped but did create some 32bit object files.

It's important to note my Sempron is a socket 754 (not socket A which would look like an Athlon XP).

I type make and here's the output:

Making all in utilities
make[2]: Entering directory `/usr/src/cvs/gnash/utilities'
/bin/sh ../libtool --tag=CXX --mode=link g++ -g -O2 -pthread
-march=athlon64 -W -Wall -Wcast-align -Wcast-qual

it recognizes my cpu as "-march=athlon64" when it's definitely not ... I have an AMD Sempron 3000+ without the 64bit extensions.

My system is basically Slackware 10.2 with a bunch of my own additions (like a current customized 2.6.21 kernel).

Probably need access to that system to be able to fix this.

By contrast, a Debian AMD Athlon MP is recognised as -march-athlon-xp which seems right.
