Subject: [Qemu-devel] [PATCH 4/9] target/m68k: Use lookup_and_goto_tb for DISAS_JUMP
Date: Fri, 11 May 2018 21:59:45 -0700 [thread overview]
Message-ID: <20180512045950.12386-7-richard.henderson@linaro.org> (raw)
In-Reply-To: <20180512045950.12386-1-richard.henderson@linaro.org>
These are all indirect or out-of-page direct jumps.
We can indirectly chain to the next TB without going
back to the main loop.
