That "non-sense" are the capabilities of your processor.

Are the asterisks (*) manually added by you?

File "cpufeature.h" (not localizable in my system) holds some data:

Greetings,

does Debian labeled for AMD-64 run on Pentium cpu family 6?

Ah, okay. Then the "lm" flag indicates your processor can run 64-bits
OSes.

X-)

I also feel like that in many fields (no one knows all). I can "guess"
what the flags are but I have to read the docs to have a fully
understanding of them.

Yes, your processor is 64-bits capable.

But you can still find in the market processors that are only 32-bits,
like some of the Intel's Atom family.

Yes, you can. But that does not mean 64-bits is better for your
computer. Don't expect to see any enhancement with a 64-bits OS just
because you install it in your machine.

I would not say that. Many benchmarks have demonstrated that with low
ram ( Thanks for your patience and nice exchange of ideas.

You're welcome.
