Subject: [dpdk-dev] [PATCH 2/3] devtools/test-meson-builds: support older compilers
Date: Wed, 10 Apr 2019 21:52:23 +0100	[thread overview]
Message-ID: <20190410205224.69977-3-bruce.richardson@intel.com> (raw)
In-Reply-To: <20190410205224.69977-1-bruce.richardson@intel.com>

Older versions of GCC, such as on Redhat/CentOS 7, don't support
-march=nehalem, but need -march=corei7 instead.
