We would really like to thank you & the team for considering our request,

and really appreciate for providing all the possible options to support AIX.

As we already validated that these alignment specific issues are resolved

with the latest versions of the compilers (gcc/ibm-clang). We would request

you to use the latest versions for the build.

We are already working with the internal team in procuring the nodes

for the buildfarm, which can be accessible by the community.

We would really appreciate you for providing the possible options

and we are very much inclined to these above approaches.
