Subject: [PATCH v2 09/48] Turn value_parent into method
Date: Fri, 10 Feb 2023 14:52:27 -0700 [thread overview]
Message-ID: <20230209-submit-value-fixups-2023-v2-9-b0b27fd97177@tromey.com> (raw)
In-Reply-To: <20230209-submit-value-fixups-2023-v2-0-b0b27fd97177@tromey.com>
This changes value_parent to be a method of value. Much of this patch
was written by script.
Approved-By: Simon Marchi <simon.marchi@efficios.com>
