Subject: [PULL 55/88] target/riscv: rvv-1.0: integer comparison instructions
Date: Mon, 20 Dec 2021 14:56:32 +1000 [thread overview]
Message-ID: <20211220045705.62174-56-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20211220045705.62174-1-alistair.francis@opensource.wdc.com>
From: Frank Chang <frank.chang@sifive.com>
* Sign-extend vmselu.vi and vmsgtu.vi immediate values.
* Remove "set tail elements to zeros" as tail elements can be unchanged
for either VTA to have undisturbed or agnostic setting.
