Subject: [PATCH v3 33/50] Turn value_incref and value_decref into methods
Date: Sun, 12 Feb 2023 20:15:49 -0700 [thread overview]
Message-ID: <20230209-submit-value-fixups-2023-v3-33-45e91a20c742@tromey.com> (raw)
In-Reply-To: <20230209-submit-value-fixups-2023-v3-0-45e91a20c742@tromey.com>
This changes value_incref and value_decref to be methods of value.
Much of this patch was written by script.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
