First off, sorry this was sent multiple times to the list, Naveen
didn't know Marvell's internal email SMTP server was delaying the mail
so much; he didn't realize it went through so he sent it again. I let
him know next time to send it and come back in an hour to see if it
made it through for next time.
Ping?
Thanks,
Andrew

[PATCH] Add scalar_storage_order support to C++
From: Naveen H S
This patch adds support scalar_storage_order attribute to C++ front-end.
It treats the opposite order fields similar as the packed fields are
treated such that they will not bind to references.
For arrays, the attributes applies to the inner type rather than the array
type similar. The code is similar to how it is handled in the C front-end.

[PATCH] Add scalar_storage_order support to C++
From: Naveen H S
This patch adds support scalar_storage_order attribute to C++ front-end.
It treats the opposite order fields similar as the packed fields are
treated such that they will not bind to references.
For arrays, the attributes applies to the inner type rather than the array
type similar. The code is similar to how it is handled in the C front-end.
