Subject: [PATCH v3 20/28] target/riscv: Use translator_use_goto_tb
Date: Thu,  8 Jul 2021 09:40:42 -0700	[thread overview]
Message-ID: <20210708164050.711967-21-richard.henderson@linaro.org> (raw)
In-Reply-To: <20210708164050.711967-1-richard.henderson@linaro.org>

Just use translator_use_goto_tb directly at the one call site,
rather than maintaining a local wrapper.
