Subject: [PATCH 05/17] dyndbg: drop NUM_TYPE_ARRAY
Date: Mon, 04 May 2026 14:45:11 -0600 [thread overview]
Message-ID: <20260504-dd-cleanups-2-v1-5-6fdd24040642@gmail.com> (raw)
In-Reply-To: <20260504-dd-cleanups-2-v1-0-6fdd24040642@gmail.com>
ARRAY_SIZE works here, since array decl is complete.
no functional change
