Thank you for the review. New patch attached.

Thanks - this looks very straightforward and nice now! Just one minor nit below:

+        add             x4, x4, x5, sxtw            // src1 += srcPadding
+        add             x9, x9, x5, sxtw            // src2 += srcPadding
+        add             x0, x0, x1, sxtw            // dst1 += dstPadding1
+        add             x2, x2, x3, sxtw            // dst2 += dstPadding2

Since you're doing sxtw, I would have expected to have the last register referenced as wN, not xN. I'd guess that some picky versions of assemblers could error out due to this, so it could be good to change that just to be safe.

Other than that, this looks extremely straightforward and nice.
