Hi Alan,

I am failing to apply your patch series to the latest gdb sources. Apparently,
your patch series needs a re-base over most recent gdb sources as there has
not been a commit since these patches have been posted.

Generally its a good idea to generate patches using git format-patch and
send patches using git send-email. Patches need to be based off the most
recent gdb commit that is available at the time of sending them for review.
If you use git format-patch to generate patches from your local commits it
would become very easy for a reviewer to just apply those patches using
"git apply" in their local branches.

Kindly post a patchset that works with a known version of gdb sources in
order for your patches to be tested/reviewed upstream.

Thanks!
