-Date: Sun, 29 Mar 2020 20:08:32 +0900
-Subject: [PATCH 2/4] gcc-plugins: drop support for GCC <= 4.7
-
-Nobody was opposed to raising minimum GCC version to 4.8 [1]
-So, we will drop GCC <= 4.7 support sooner or later.
-
-We always use C++ compiler for building plugins for GCC >= 4.8.
-
-This commit drops the plugin support for GCC <= 4.7 a bit earlier,
-which allows us to dump lots of code.
