Subject: [PATCH v4 02/16] eal: pack structures when building with MSVC
Date: Mon, 15 Apr 2024 17:04:59 -0700 [thread overview]
Message-ID: <1713225913-20792-3-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1713225913-20792-1-git-send-email-roretzla@linux.microsoft.com>
Add __rte_msvc_pack to all __rte_packed structs to cause packing
when building with MSVC.
Remove __rte_packed where it appears natural alignment without
packing would produce the same layout or the struct is internal.
