 921  * tcg_qemu_tb_exec:
 922  * @env: CPUArchState * for the CPU
 923  * @tb_ptr: address of generated code for the TB to execute
 924  *
 925  * Start executing code from a given translation block.
 926  * Where translation blocks have been linked, execution
 927  * may proceed from the given TB into successive ones.
 928  * Control eventually returns only when some action is needed
 929  * from the top-level loop: either control must pass to a TB
 930  * which has not yet been directly linked, or an asynchronous
 931  * event such as an interrupt needs handling.
 932  *
 933  * The return value is a pointer to the next TB to execute
 934  * (if known; otherwise zero). This pointer is assumed to be
 935  * 4-aligned, and the bottom two bits are used to return further
 936  * information:
 937  *  0, 1: the link between this TB and the next is via the specified
 938  *        TB index (0 or 1). That is, we left the TB via (the equivalent
 939  *        of) "goto_tb <index>". The main loop uses this to determine
 940  *        how to link the TB just executed to the next.
 941  *  2:    we are using instruction counting code generation, and we
 942  *        did not start executing this TB because the instruction counter
 943  *        would hit zero midway through it. In this case the next-TB pointer
 944  *        returned is the TB we were about to execute, and the caller must
 945  *        arrange to execute the remaining count of instructions.
 946  *  3:    we stopped because the CPU's exit_request flag was set
 947  *        (usually meaning that there is an interrupt that needs to be
 948  *        handled). The next-TB pointer returned is the TB we were
 949  *        about to execute when we noticed the pending exit request.
 950  *
 951  * If the bottom two bits indicate an exit-via-index then the CPU
 952  * state is correctly synchronised and ready for execution of the next
 953  * TB (and in particular the guest PC is the address to execute next).
 954  * Otherwise, we gave up on execution of this TB before it started, and
 955  * the caller must fix up the CPU state by calling the CPU's
 956  * synchronize_from_tb() method with the next-TB pointer we return (falling
 957  * back to calling the CPU's set_pc method with tb->pb if no
 958  * synchronize_from_tb() method exists).
 959  *
 960  * Note that TCG targets may use a different definition of tcg_qemu_tb_exec
 961  * to this default (which just calls the prologue.code emitted by
 962  * tcg_target_qemu_prologue()).
