[v1] target/m68k: Convert to TranslatorOps

[Qemu-devel] [PATCH 4/9] target/m68k: Use lookup_and_goto_tb for DISAS_JUMP

Posted by Richard Henderson 7 years, 5 months ago

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.
