What would be enough testing to ensure the change would get into gcc 6 ?
Maybe a gcc bootstrap build or a linux kernel build.
Maybe a full build of all the packages in Fedora / OpenSuse / Debian / Ubuntu.
I don't have ARM here, but this might be enough excuse to get
access to the compile farm or to some other ARM server.
