Subject: [FFmpeg-devel] [PATCH] hevcdsp_idct_neon.S: Avoid unnecessary mov.
Date: Wed, 26 Jul 2023 21:15:27 +0200
Message-ID: <20230726191527.1623-1-Reimar.Doeffinger@gmx.de> (raw)
From: Reimar Döffinger <Reimar.Doeffinger@gmx.de>
ret can be given an argument instead.
This is also consistent with how other assembler code
