Subject: [PATCH v2] buildtools: fix invalid symbols
Date: Mon,  1 Jul 2024 10:33:15 +0000	[thread overview]
Message-ID: <20240701103315.835249-1-mingjinx.ye@intel.com> (raw)
In-Reply-To: <20240627101144.665413-1-mingjinx.ye@intel.com>

Elf files generated by higher version compilers wrap multiple
symbols prefixed with "this_pmd_name".

The patch uses the regex "^this_pmd_name[0-9]+$" to match the
symbol name.

Bugzilla ID: 1466
Fixes: 6c4bf8f42432 ("buildtools: add Python pmdinfogen")
Cc: stable@dpdk.org
