Subject: [PATCH v2 04/16] target/riscv: Restrict 'rv128' machine to TCG accelerator
Date: Mon,  3 Jul 2023 20:31:33 +0200	[thread overview]
Message-ID: <20230703183145.24779-5-philmd@linaro.org> (raw)
In-Reply-To: <20230703183145.24779-1-philmd@linaro.org>

We only build for 32/64-bit hosts, so TCG is required for
128-bit targets.
