Subject: [PATCH qemu v10 04/14] target/riscv: rvv: Add tail agnostic for vv instructions
Date: Tue, 01 Mar 2022 01:07:38 -0800 [thread overview]
Message-ID: <165107198903.23549.13907705840662008250-4@git.sr.ht> (raw)
In-Reply-To: <165107198903.23549.13907705840662008250-0@git.sr.ht>
From: eopXD <eop.chen@sifive.com>
This is the first commit regarding the tail agnostic behavior.
Added option 'rvv_ta_all_1s' to enable the behavior, the option
is default to false.

Subject: [PATCH qemu v10 04/14] target/riscv: rvv: Add tail agnostic for vv instructions
Date: Wed, 27 Apr 2022 15:06:35 -0000 [thread overview]
Message-ID: <165107198903.23549.13907705840662008250-4@git.sr.ht> (raw)
In-Reply-To: <165107198903.23549.13907705840662008250-0@git.sr.ht>
From: eopXD <eop.chen@sifive.com>
This is the first commit regarding the tail agnostic behavior.
Added option 'rvv_ta_all_1s' to enable the behavior, the option
is default to false.
Signed-off-by: eop Chen <eop.chen@sifive.com>
