Subject: [dpdk-dev] [PATCH] devtools: give some hints for ABI errors
Date: Wed,  8 Jul 2020 12:22:12 +0200
Message-ID: <20200708102212.3311-1-david.marchand@redhat.com> (raw)

abidiff can provide some more information about the ABI difference it
detected.
In all cases, a discussion on the mailing must happen but we can give
some hints to know if this is a problem with the script calling abidiff,
a potential ABI breakage or an unambiguous ABI breakage.
