I've been out-of-office for a while. While I was away, Wladimir contacted
me off-list to confirm that this was correct.

I've committed the patch as revision r236914.

Thanks for the patch Wladimir!

Close... This should look like:

2016-04-25  Wladimir J. van der Laan  

* config/aarch64/arm_neon.h (vdupb_laneq_s): Remove spurious
attribute __unused__

Can you confirm that this is how you want your name and email address
to appear in the ChangeLog. If so, I'll commit the patch for you.

I intend to do this, but indeed let's not hold this two-word change up on that.

The patch looks good to me, and is OK for trunk... Now for all the
administration!

This patch will need a ChangeLog entry [1], please draft one that I can
use when I apply the patch.

I'm guessing that you don't have a copyright assignment on file with the
FSF. While trivial changes like this don't generally need one, if you plan
to contribute more substantial changed to GCC in future, you may want to
start the process (see [2]).

Thanks for the contribution, if you provide a ChangeLog, I'd be happy to
apply the patch.

Thanks,
James

[PATCH] AARCH64: Remove spurious attribute __unused__ from NEON intrinsic

[Wladimir J. van der Laan]

The lane parameter is not unused, so should not be marked as such.

The others were removed in https://patchwork.ozlabs.org/patch/272912/,
but this one appears to have been missed.
