[x86-64bit-papa]

thx...

... pls ignore (but, any idea what's their differences?)

searching again gives me some idea.

Pure64, no 32bit programs...

x86-64bit has 32bit compatibility layer.

correct?

I'm new to Funtoo.  Also beginner with Gentoo.

With "epro list", I noticed that there is "x86-64bit-papa".

What's the difference with "x86-64bit"?

Note, searching using Google with 'site:funtoo.org "x86-64bit-papa"' doesn't give any results with explanation.
