A TCG "basic block" corresponds to a list of instructions terminated
by a branch instruction.
An operation with "undefined behavior" may result in a crash.
An operation with "unspecified behavior" shall not crash. However,
the result may be one of several possibilities so may be considered
an "undefined result".
