Since this is a backport from mainline, your ChangeLog entry needs mention that fact. Also, is the mainline patch associated with a bugzilla entry? If so, that also needs to be included. See for example the following patch submission and what its ChangeLog entries look like: https://gcc.gnu.org/ml/gcc-patches/2018-01/msg01869.html Peter
