[mythtv] CPU detection/optimization

Wed, 30 Mar 2005 12:55:08 -0800

When running the configure script I notice that my CPU (model name : AMD Sempron(tm) 2200+) is detected and compiled as 'pentiumpro'. There was a script posted to one of the lists called gccopts, which on my system reports:

 -march=athlon-xp -mfpmath=sse -msse -mmmx -m3dnow

And upon reading the following:

http://home.comcast.net/~jcunningham63/linux/GCC_Optimization_apollo.html

it would appear that there could be some further optimization of the configure file, at least in my case. I will be doing some testing tonight of the various options, does anyone have any advice in terms of what to test, or if this has been done already and it's not worth the effort, please let me know.

I will post results and a patched configure if I find anything of value.

Thanks
Tom
