Subject: [PULL 12/23] target/riscv: Move/refactor ISA extension checks
Date: Wed, 25 May 2022 08:44:17 +1000 [thread overview]
Message-ID: <20220524224428.552334-13-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>
We should separate "check" and "configure" steps as possible.
This commit separates both steps except vector/Zfinx-related checks.
