[Qemu-discuss] Details about TranslationBlock

I've been reading qemu's source code.
but I'm not clear about these Member variables of struct TranslatonBlock in $(qemu)/exec-all.h:
+++uint16_t tb_next_offset[2]; /* offset of original jump target */
+++uint16_t tb_jmp_offset[4]; /* offset of jump instruction */
+++uintptr_t tb_next[2]; /* address of jump generated code */
and I was confused about the real meaning of "taken" and "not taken".
Could there anyone show the details?

Best Regards.
