Subject: [PULL 05/33] target/riscv: fix TB_FLAGS bits overlapping bug for rvv/rvh
Date: Fri, 22 Oct 2021 23:37:44 +1000	[thread overview]
Message-ID: <20211022133812.3972903-6-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20211022133812.3972903-1-alistair.francis@opensource.wdc.com>

From: Frank Chang <frank.chang@sifive.com>

TB_FLAGS mem_idx bits was extended from 2 bits to 3 bits in
commit: c445593, but other TB_FLAGS bits for rvv and rvh were
not shift as well so these bits may overlap with each other when
rvv is enabled.
