Subject: [PULL 10/23] target/riscv: Change "G" expansion
Date: Wed, 25 May 2022 08:44:15 +1000 [thread overview]
Message-ID: <20220524224428.552334-11-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20220524224428.552334-1-alistair.francis@opensource.wdc.com>
From: Tsukasa OI <research_trasio@irq.a4lg.com>
On ISA version 20190608 or later, "G" expands to "IMAFD_Zicsr_Zifencei".
Both "Zicsr" and "Zifencei" are enabled by default and "G" is supposed to
be (virtually) enabled as well, it should be safe to change its expansion.
