39 These functions convert relative addresses to absolute addresses
40 in CALL instructions to increase the compression ratio.
45 ip - current virtual Instruction Pinter (IP) value
46 state - state variable for x86 converter
47 encoding - 0 (for decoding), 1 (for encoding)
50 state - state variable for x86 converter
53 The number of processed bytes. If you call these functions with multiple calls,
54 you must start next call with first byte after block of processed bytes.
56 Type Endian Alignment LookAhead
65 size must be >= Alignment + LookAhead, if it's not last block.
66 If (size < Alignment + LookAhead), converter returns 0.
73 ; size must be >= Alignment + LookAhead, if it's not last block
