New to Gentoo. So I looked over news items after succeeding in getting a booting system. News item number 10 discusses a script for generating output that goes under the new flag CPU_FLAGS_X86=. Though the news item says nothing about where that CPU_FLAGS_X86= entry should go, it seems to me a safe inference that it belongs in /etc/portage/make.conf. Additionally, however, there is no directive about where in make.conf that line should go. So I need to ask for clarification here: is CPU_FLAGS_X86= supposed to be a separate item on a new line within that file, as shown at http://pisarenko.net/files/80211ac/make.conf ? Or does it go under USE= or in some other spot within that file? Clarifications wil be appreciated.

In order not to lose CPU-specific optimizations, users will be required to update their make.conf (and package.use) file.

;)

There are no certain spots for that - you can put it wherever you like inside make.conf, as long as you set the variable correctly.

In other words, your make.conf is correct.

jamtat,

make.conf sets the environment for emerge.
Its another environment varable. The order of entries in make.conf is not relevant to the meaning it conveys.

It can go anywhere.

Thanks for the clarifications, genstorm and NeddySeagoon. I thiink my only other question related to this is whether, if under USE=, there are some of the same flags that have been output by the Python program as belonging under CPU_FLAGS_X86=, those entries under USE= need to be removed?

They won't have an effect any longer under USE, so they should be deleted, but wouldn't do any harm.
