How have you enabled mmx and friends? They are use.masked for the amd64 profile. As far as I know mmx2 isn't supported on the amd64 either. The USE flags are masked as most of the mmx/sse stuff is x86 asm and so breaks on the amd64 architecture. Where packages have working x86_64 asm we hard enable it in the ebuilds. I am unable to reproduce your bug and am marking it as invalid, please reopen if I am mistaken. Yes I've anabled them by hand (through /etc/make.profile/use.mask -mmx -sse...) because I thought that having such a powerful processor without exploiting its extension was bad... Sorry if I tried. But then, do I have to wait till gcc and friends support them or it's better to use a 32bit os :'-( ? Kind regards Sorry I've now understanded what you mean... [I'm a bit a dog with English...] Thank you for your infos and support! |
