Subject: [GIT PULL] gcc-plugin updates for v5.1-rc1
Date: Mon, 4 Mar 2019 09:48:02 -0800 [thread overview]
Message-ID: <20190304174802.GA6629@beast> (raw)
Hi Linus,
Please pull these gcc-plugin changes for v5.1-rc1. This adds additional
type coverage to the existing structleak plugin and adds a large set of
selftests to help evaluate stack variable zero-initialization coverage
(which can be used to test whatever instrumentation might be performing
zero-initialization: either with the structleak plugin or with Clang's
coming "-ftrivial-auto-var-init=zero" option).
Note that there is a minor conflict seen in linux-next with KASAN changes
in -mm, which removes the !KASAN_EXTRA depends from structleak. sfr's
resolution is correct:

Thanks!
-Kees
