Hi all,
This patch to changes.html mentions the xgene1 support in GCC 5 for arm
and aarch64 and also the FreeBSD support for ARM.
Is this ok?
The repetitive nature of all these new cpus being added looks rather
wooden. I think it would be better to merge them into one change block,
that lists all the cpus and their internal names, then mentions once at
the end that these names can be used as arguments to -mcpu and -mtune.
Yeah, that makes sense. I've incorporated the feedback.
Here's a proposed patch.
How's this?

R.
I added the FreeBSD part in the Operating Systems section similar to
Dragonfly BSD.
Thanks,
Kyrill
