Subject: [PATCH v2 14/24] target/mips: Move msa_reset() to mod-msa_helper.c
Date: Tue, 15 Dec 2020 23:57:47 +0100 [thread overview]
Message-ID: <20201215225757.764263-15-f4bug@amsat.org> (raw)
In-Reply-To: <20201215225757.764263-1-f4bug@amsat.org>
translate_init.c.inc mostly contains CPU definitions.
msa_reset() doesn't belong here, move it with the MSA
helpers.
One comment style is updated to avoid checkpatch.pl warning.
