From: Richard Henderson Date: Sat, 12 May 2018 05:02:45 +0000 (-0700) Subject: target/m68k: Use lookup_and_goto_tb for DISAS_JUMP X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=8aaf7da9c3b1f282b5a123de3e87a2e6ca87f3b9;p=qemu.git target/m68k: Use lookup_and_goto_tb for DISAS_JUMP 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.
