Subject: [PATCH v2] test/ipsec: fix build with GCC 12
Date: Thu, 16 Jun 2022 11:33:20 +0200	[thread overview]
Message-ID: <20220616093320.884583-1-david.marchand@redhat.com> (raw)
In-Reply-To: <20220518101657.1230416-13-david.marchand@redhat.com>

GCC 12 raises the following warning:

In function ‘_mm256_loadu_si256’,
    inlined from ‘rte_mov32’ at
        ../lib/eal/x86/include/rte_memcpy.h:319:9,

      |          ^~~~
../app/test/test_ipsec.c: In function ‘setup_test_string.constprop’:

    ‘null_plain_data’ of size 108

Add a hint so that the compiler understands the copied data is within
the passed string boundaries.

Changes since v1:
- let the code as is, simply added a RTE_VERIFY hint,
