+Subject: plugin event for C/C++ declarations
+From: Brian Hackett <bhackett1024 at gmail dot com>
+To: gcc-patches at gcc dot gnu dot org
+
+Hi, this patch adds a new plugin event FINISH_DECL, which is invoked
+at every finish_decl in the C and C++ frontends. Previously there did
+not seem to be a way for a plugin to see the definition for a global
+that is never used in the input file, or the initializer for a global
+which is declared before a function but defined after. This event
+isn't restricted to just globals though, but also locals, fields, and
+parameters (C frontend only).
