Subject: [dpdk-dev] [PATCH 1/1] doc: add deprecation notice for CPU build flags
Date: Wed,  5 Aug 2020 15:21:41 +0100
Message-ID: <20200805142141.32337-2-bruce.richardson@intel.com> (raw)
In-Reply-To: <20200805142141.32337-1-bruce.richardson@intel.com>

The RTE_MACHINE_CPUFLAGS_* macros in DPDK build just duplicate info from
the compiler macros, so we can remove them and just use the compiler
versions directly.

+* build macros: The macros defining RTE_MACHINE_CPUFLAG_* will be removed
+  from the build. The information provided by these macros is available
+  through standard compiler macros. For example, RTE_MACHINE_CPUFLAG_SSE3
+  duplicates the compiler-provided macro __SSE3__.

 * kvargs: The function ``rte_kvargs_process`` will get a new parameter
   for returning key match count. It will ease handling of no-match case.
