I think you need to go ahead and end the TB and resync immediately.
Just set dc->base.is_jmp = DISAS_UPDATE_NOCHAIN instead.
Is there a rule for when we should set is_jmp to DISAS_UPDATE_NOCHAIN,
when we should set it to DISAS_UPDATE_EXIT, and when we should call
gen_lookup_tb() ? We seem to use all three methods at various points
for "I changed some CPU state and want to end the TB"...
UPDATE_EXIT is for when you need to return to the main loop; UPDATE_NOCHAIN merely avoids
goto_tb. Direct use of gen_goto_ptr should be reserved for branches (which I think is
already the case).
