Hi all,
This patch adds a mention of the new native cpu detection feature in aarch64 GNU/Linux.
Gerald, this is a patch against htdocs/gcc-6/changes.html and I thought I had seen the 'changes' link
in gcc.gnu.org earlier but I don't see it now (there's only a release criteria link).
Is this a bug?
Ok to apply?
Thanks,
Kyrill

Submit a patch?

I think I remember Gerald saying in the past that it is within the
remit of port maintainers/reviewers to OK these, but be ready to revert or
update it if I am wrong!
This is fine to apply.
Thanks,
James

You were (and are) very much quite right, James. :-)
(And given that Gerald is not always able to respond as quickly as
he'd like, this mail being a "nice" example, this just makes sense.)
