From ce6ed1c4c9876c2880f52f18c41ef2a30d070bc5 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Thu, 4 Mar 2021 20:37:08 +0900 Subject: kbuild: rebuild GCC plugins when the compiler is upgraded Linus reported a build error due to the GCC plugin incompatibility when the compiler is upgraded. [1] GCC plugins are tied to a particular GCC version. So, they must be rebuilt when the compiler is upgraded. This seems to be a long-standing flaw since the initial support of GCC plugins. Extend commit 8b59cd81dc5e ("kbuild: ensure full rebuild when the compiler is updated"), so that GCC plugins are covered by the compiler upgrade detection.
