Subject: [PATCH v4 01/16] eal: provide pack start macro for MSVC
Date: Mon, 15 Apr 2024 17:04:58 -0700	[thread overview]
Message-ID: <1713225913-20792-2-git-send-email-roretzla@linux.microsoft.com> (raw)
In-Reply-To: <1713225913-20792-1-git-send-email-roretzla@linux.microsoft.com>

MSVC struct packing is not compatible with GCC provide a macro that can
be used to push existing pack value and sets packing to 1-byte. The
existing __rte_packed macro is then used to restore the pack value
prior to the push.

Instead of providing macros exclusively for MSVC and for GCC the
existing macro is deliberately utilized to trigger a warning if no
existing packing has been pushed allowing easy identification of
locations where the __rte_msvc_pack is missing.
