--- Comment #42 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Oh, and we surely need to document this in gcc-7/changes.html, and I'd think we should make sure to also document the earlier ARM ABI change in gcc-5/changes.html for GCC 5.2 when it has changed and document there the change was only fixed in 7.1.
