Subject: [dpdk-dev] [PATCH 1/2] build: avoid non supported -march on ppc (meson)
Date: Wed, 14 Nov 2018 12:34:52 +0100
Message-ID: <20181114113453.24852-1-christian.ehrhardt@canonical.com> (raw)

So far only if machine was "native" it did use the re-direction to
not set -march on ppc64 (where -march is not supported).
We have to use mcpu/mtune in any case on ppc for whatever someone using
the build system defines as machine.
