Are there other arches using CPU_FLAGS_X86? ;) But seriously, the item |
19 |
is quite arch-specific. Other arches are likely to have kinda specific |

flags with rules for choosing them, another script etc. |

I guess that kinda works. So far 'quse -D mmx' has the nicest output |

but I don't want people to rely on portage-utils. |

I just recall it's a frequent issue, people missing SSE3 and mixing it |
39 |
up with SSSE3. |
