rc_bit

Name: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

Proto:static __always_inline int rc_bit(struct rc_dec *rc, uint16_t *prob)

Type:int

Parameter:

Type	Parameter	Name
struct rc_dec *	rc
uint16_t *	prob

502

Read the next input byte if needed.

503

bound = (range >> RC_BIT_MODEL_TOTAL_BITS) * prob

504

If code < bound Then

505

range = bound

506

prob += RC_BIT_MODEL_TOTAL - prob >> RC_MOVE_BITS

507

bit = 0

508

Else

509

range -= bound

510

code -= bound

511

prob -= prob >> RC_MOVE_BITS

512

bit = 1

515

Return bit

Name	Describe
rc_bittree	Decode a bittree starting from the most significant bit.
rc_bittree_reverse	Decode a bittree starting from the least significant bit.
lzma_literal	Decode a literal (one 8-bit byte)
lzma_len	Decode the length of the match into s->lzma.len.
