Subject: [PATCH v2 20/37] target/riscv: 8-bit Multiply with 32-bit Add Instructions
Date: Thu, 10 Jun 2021 15:58:51 +0800	[thread overview]
Message-ID: <20210610075908.3305506-21-zhiwei_liu@c-sky.com> (raw)
In-Reply-To: <20210610075908.3305506-1-zhiwei_liu@c-sky.com>

Four "signed or unsigned 8 x signed or unsigned 8" with 32-bit addition
(32 = 32 + 8x8 + 8x8 + 8x8 + 8x8).
