/*
|
|
These functions convert relative addresses to absolute addresses
|
|
in CALL instructions to increase the compression ratio.
|
|
|
|
In:
|
|
data - data buffer
|
|
size - size of data
|
|
ip - current virtual Instruction Pinter (IP) value
|
|
state - state variable for x86 converter
|
|
encoding - 0 (for decoding), 1 (for encoding)
|
|
|
|
Out:
|
|
state - state variable for x86 converter
|
|
|
|
Returns:
|
|
The number of processed bytes. If you call these functions with multiple calls,
|
|
you must start next call with first byte after block of processed bytes.
|
|
|
|
Type Endian Alignment LookAhead

x86 little 1 4

|
|
PPC big 4 0
|
|
SPARC big 4 0
|
|
IA64 little 16 0
|
|
|
|
size must be >= Alignment + LookAhead, if it's not last block.
|
|
If (size < Alignment + LookAhead), converter returns 0.
|
|
|
|
Example:
|
|
|
|
UInt32 ip = 0;
|
|
for ()
|
|
{
|
|
; size must be >= Alignment + LookAhead, if it's not last block

SizeT processed = Convert(data, size, ip, 1);
|
|
data += processed;
|

size -= processed;
