rc_bit

函数名称：Decode one bit. In some versions, this function has been splitted in three* functions so that the compiler is supposed to be able to more easily avoid* an extra branch. In this particular version of the LZMA decoder, this

函数原型：static __always_inline int rc_bit(struct rc_dec *rc, uint16_t *prob)

返回类型：int

参数：

类型	参数	名称
struct rc_dec *	rc
uint16_t *	prob

502

Read the next input byte if needed.

503

bound等于range右移RC_BIT_MODEL_TOTAL_BITS位的值乘prob

504

如果code小于bound则

505

range等于bound

506

prob加等于RC_BIT_MODEL_TOTAL减prob右移RC_MOVE_BITS位

507

bit等于0

508

否则

509

range减等于bound

510

code减等于bound

511

prob减等于prob右移RC_MOVE_BITS位

512

bit等于1

515

返回:bit
