| 10 These functions convert relative addresses to absolute addresses | |
| 11 in CALL instructions to increase the compression ratio. | |
| 12 | |
| 13 In: | |
| 14 data - data buffer | |
| 15 size - size of data | |
| 16 ip - current virtual Instruction Pinter (IP) value | |
| 17 state - state variable for x86 converter | |
| 18 encoding - 0 (for decoding), 1 (for encoding) | |
| 19 | |
| 20 Out: | |
| 21 state - state variable for x86 converter | |
| 22 | |
| 23 Returns: | |
| 24 The number of processed bytes. If you call these functions with multiple cal
ls, | |
| 25 you must start next call with first byte after block of processed bytes. | |

| 36 size must be >= Alignment + LookAhead, if it's not last block. | |
| 37 If (size < Alignment + LookAhead), converter returns 0. | |

| 42 for () | |
| 43 { | |
