Subject: [Cocci] [PATCH 10/17] parsing_cocci: unify_ast: Reflect attributefn in AST visitor
Date: Thu, 16 Jul 2020 18:35:14 +0530
Message-ID: <20200716130521.7717-11-jaskaran.singh@collabora.com> (raw)
In-Reply-To: <20200716130521.7717-1-jaskaran.singh@collabora.com>

The SmPL AST visitor has a function for attributes. Reflect these
changes in unify_ast.ml. Also add a few fixes w/r/t the usage of
for_all2 for comparing attributes.
