The compilation of the master branch is failing for aarch64:

The log is so much verbose that I am not able to understand what
is really wrong.
Please help to diagnose and fix, thanks.
A discussion about this:
http://mails.dpdk.org/archives/dev/2019-June/134012.html
I see the error now.
It is printing the full log after the error, so I missed the error
at the top.
I've read your comment about a possible error with the patch
removing weak functions but neither me nor Bruce were able to
reproduce
it.
What is the condition to see this compiler warning?
It is only on ARM, and only when the neon intrinsics are in use.
I am not able to reproduce it from the tip of master.
I am using:
gcc (Ubuntu 8.3.0-6ubuntu1~18.04) 8.3.0
From the log on Travis, looks like the compiler is:
gcc (Ubuntu 5.4.0-6ubuntu1~16.04.11) 5.4.0 20160609
Is this the issue?
Why are we seeing the error now?
I tested with gcc-5 (Ubuntu/Linaro 5.5.0-12ubuntu1) 5.5.0 20171010, it
works fine. I cannot get hold of 5.4.0. Not sure if needs to be supported.
Are there any issues in upgrading to 7 or 8?
I have tested it on my ubuntu 16.04 vm on commit
8cb511bb94ad92a76990f175cac76bb13d51daba (head of master seems to be
failing for other reasons on my vm).
I tested the following gcc versions:
gcc 5.5.0 "cc (Ubuntu 5.5.0-12ubuntu1~16.04) 5.5.0 20171010"
gcc 7.4.0 "cc (Ubuntu 7.4.0-1ubuntu1~16.04~ppa1) 7.4.0"
gcc 8.1.0 "cc (Ubuntu 8.1.0-5ubuntu1~16.04) 8.1.0"
Though I am not able to reproduce the issue.
Could you the following patch fixing the issue?
http://patches.dpdk.org/patch/54501/
Yes, I have tested this patch on travis and it fixes the issue. see:
