-/* DisasContext is_jmp field values
- *
- * is_jmp starts as DISAS_NEXT. The translator will keep processing
- * instructions until an exit condition is reached. If we reach the
- * exit condition and is_jmp is still DISAS_NEXT (because of some
- * other condition) we simply "jump" to the next address.
- * The remaining exit cases are:
- *
- * DISAS_JUMP - Only the PC was modified dynamically (e.g computed)
- * DISAS_TB_JUMP - Only the PC was modified statically (e.g. branch)
- *
- * In these cases as long as the PC is updated we can chain to the
- * next TB either by exiting the loop or looking up the next TB via
- * the loookup helper.
- *
- * DISAS_UPDATE - CPU State was modified dynamically
- *
- * This covers any other CPU state which necessities us exiting the
- * TCG code to the main run-loop. Typically this includes anything
- * that might change the interrupt state.
- *
- * Individual translators may define additional exit cases to deal
- * with per-target special conditions.
