[dpdk-stable] patch 'build: set -mfpu=neon flag for armv7-a with meson' has been queued to stable release 18.08.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 18.08.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 12/08/18. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Kevin Traynor

[ upstream commit daf6c3c10e91b1c0dcb872f385116dc4aa477556 ]

Building on armv7a with meson currenctly fails:

/usr/lib/gcc/arm-linux-gnueabihf/8/include/arm_neon.h:10369:1: error:
    inlining failed in call to always_inline ‘vld1q_s32’: target
    specific option mismatch

Set -mfpu=neon on that architecture like the legacy makefiles do to fix
the issue.

Fixes: b1d48c41189a ("build: support ARM with meson")
