Subject: [dpdk-dev] [PATCH v1 10/12] gcc/arm: avoid alignment errors to break build
Date: Sat, 3 Oct 2015 10:58:16 +0200 [thread overview]
Message-ID: <7120b4518a6c3d048912a12705ed92853c3fd727.1443737626.git.viktorin@rehivetech.com> (raw)

In-Reply-To: <cover.1443737626.git.viktorin@rehivetech.com>
There several issues with alignment when compiling for ARMv7.
They are not considered to be fatal (ARMv7 supports unaligned
access of 32b words), so we just leave them as warnings. They
should be solved later, however.
