Subject: [dpdk-dev] [PATCH 0/3] Avoid cast-align warnings
Date: Tue, 13 Jul 2021 09:49:07 +0300 [thread overview]
Message-ID: <20210713064910.12793-1-elibr@nvidia.com> (raw)
Various functions/macros assume valid alignment for casting. Compiling
an application against it with -Werror and -Wcast-align may trigger
cast-align warnings.
To avoid those, add first (void *) castings.
Note: for eal/arm64 similar changes could be applied to
lib/eal/arm/include/rte_memcpy_64.h. I do not have a system in which I
encounter such warnings, so currently I do not post any change for it.

net: avoid cast-align warning in VLAN insert function
mbuf: avoid cast-align warning in pktmbuf mtod offset macro
eal/x86: avoid cast-align warning in x86 memcpy functions
