Subject: [PATCH 3/4] powerpc: Add -Wvla to arch CFLAGS
Date: Wed, 10 Oct 2018 16:13:07 +1100 [thread overview]
Message-ID: <20181010051308.25422-3-mpe@ellerman.id.au> (raw)
In-Reply-To: <20181010051308.25422-1-mpe@ellerman.id.au>
Upstream has declared that Variable Length Array's (VLAs) are a bad
idea, and eventually -Wvla will be added to the top-level Makefile. We
can go one better and make sure we don't introduce any more by adding
it to the arch Makefile.
