Subject: [PATCH 14/33] target/mips: Add emulation of MXU Q16ADD instruction
Date: Thu, 8 Jun 2023 13:42:03 +0300 [thread overview]
Message-ID: <20230608104222.1520143-15-lis8215@gmail.com> (raw)
In-Reply-To: <20230608104222.1520143-1-lis8215@gmail.com>
The instruction adds/subtracts four 16-bit packed in XRb and XRc.
Placing packed 16-bit results in XRa and XRd.
