--- Comment #4 from Roland Illig <roland.illig at gmx dot de> --- Created attachment 46207 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=46207&action=edit linter that checks diagnostics that only differ in placeholder content Using polib, writing the linter was not trivial, but still easy. When you consider to commit this, please coordinate with bug 90176 since I have submitted an older version of the linter there, too. Since the linter gets more and more features, it may be the right time to rename it to something more generic.
