Re: tune gcc

Of course, if you find some convincing evidence that using processor specific optimisations does get a large gain, post them here! It'll at least quell the stupid 'Debian needs a separate archive for every CPU model in existence!!!1' one or the other. Well, we can dream :) Well there is some stuf

Re: tune gcc

Thank you very for your replies. I guess it we may use the `apt-build' facilities to rebuild our favorite scientific libraries: unfortunately the `apt-build' package conflicts with `pentium-builder'. Nevertheless, a quick look leads to think that they can be merged as they both use a wrapper. Is i
