[gentoo-user] USE-flags description?

[Jarry]

Hi Gentoo-users,

where can I find description of *all* USE flags? I checked
/usr/portage/profiles/use.desc and use.local.desc but still
I can not find some...

cpuinfo2cpuflags-x86 suggested my CPU_FLAGS_X86 should be:
"aes avx mmx mmxext popcnt sse sse2 sse3 sse4_1 sse4_2 ssse3"

But I'd like to know what they means, but I could not find
any description for "aes" and "popcnt"...

Jarry

You probably mean /usr/portage/profiles/desc/cpu_flags_x86.desc
Thanks, I did not know about that "desc" sub-dir at all...

A bit late, but still valid: I use ufed (use flag editor) for anything that
useflaggy that requires more than a simple lookup.
