Subject: [PATCH v3 10/19] target/microblaze: Use tcg_gen_lookup_and_goto_ptr
Date: Fri, 4 Sep 2020 12:08:33 -0700 [thread overview]
Message-ID: <20200904190842.2282109-11-richard.henderson@linaro.org> (raw)
In-Reply-To: <20200904190842.2282109-1-richard.henderson@linaro.org>
Normal indirect jumps, or page-crossing direct jumps, can use
tcg_gen_lookup_and_goto_ptr to avoid returning to the main loop
simply to find an existing TB for the next pc.
