Subject: [PATCH v2 11/23] target/microblaze: Check CF_NO_GOTO_TB for DISAS_JUMP
Date: Tue, 12 Oct 2021 09:21:47 -0700	[thread overview]
Message-ID: <20211012162159.471406-12-richard.henderson@linaro.org> (raw)
In-Reply-To: <20211012162159.471406-1-richard.henderson@linaro.org>

We were using singlestep_enabled as a proxy for whether
translator_use_goto_tb would always return false.
