Subject: [Cocci] [PATCH v3 25/26] cocci: Remove Ast_cocci.FunctionPointer
Date: Fri, 20 Mar 2020 12:31:56 +0530
Message-ID: <20200320070157.4206-26-jaskaransingh7654321@gmail.com> (raw)
In-Reply-To: <20200320070157.4206-1-jaskaransingh7654321@gmail.com>

ParenType and FunctionType are now in the SmPL AST, and these
types have replaced all productions related to the FunctionPointer
type in the SmPL parser.

Remove FunctionPointer from the SmPL ASTs, its cases and any functions
or constructs related to it from the codebase.
