Subject: [dpdk-stable] [PATCH v3 1/4] arch/arm: add vcopyq intrinsic for aarch32
Date: Wed, 24 Jun 2020 15:10:12 +0800 [thread overview]
Message-ID: <20200624071016.210656-2-ruifeng.wang@arm.com> (raw)
In-Reply-To: <20200624071016.210656-1-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")
