Subject: [PATCH 1/3] eal/riscv: fix xmm_t casting for C++
Date: Thu,  9 Jun 2022 14:16:59 +0200	[thread overview]
Message-ID: <20220609121701.716299-2-kda@semihalf.com> (raw)
In-Reply-To: <20220609121701.716299-1-kda@semihalf.com>

rte_xmm_t is a union type which wraps around xmm_t and maps its contents
to scalar structures. Since C++ has stricter type conversion rules than
C, the rte_xmm_t::x has to be used instead of C-casting.
