Subject: [dpdk-dev] [PATCH v2 1/4] arch/arm: add vcopyq intrinsic for aarch32
Date: Tue, 23 Jun 2020 14:58:53 +0800	[thread overview]
Message-ID: <20200623065856.41189-2-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20200623065856.41189-1-ruifeng.wang@arm.com>

vcopyq_laneq_u32 should be implemented for aarch32 which doesn't have
the intrinsic.
This fixes build of examples/l3fwd for armv7.

Fixes: 3c4b4024c225 ("arch/arm: add vcopyq_laneq_u32 for old gcc")
Cc: stable@dpdk.org
