Subject: [PATCH v6 04/61] target/riscv: add vector configure instruction
Date: Tue, 17 Mar 2020 23:05:56 +0800 [thread overview]
Message-ID: <20200317150653.9008-5-zhiwei_liu@c-sky.com> (raw)
In-Reply-To: <20200317150653.9008-1-zhiwei_liu@c-sky.com>
vsetvl and vsetvli are two configure instructions for vl, vtype. TB flags
should update after configure instructions. The (ill, lmul, sew ) of vtype
and the bit of (VSTART == 0 && VL == VLMAX) will be placed within tb_flags.
