Wanne 47db604b50 *** Merged Code from Multiplayer Branch Revision 2960 ***
- Virtual File System (VFS) by birdflu. This is needed for Multiplayer and is also used for Single Player. Very neat system :-)
- Multiplayer Version 1.1 + some additional features and bugfixes
* INFO: If you compile a new EXE and want to test, be sure to also use the latest SVN GameDir files in your JA2 install directory *

/*
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
ARMT little 2 2
ARM little 4 0
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;
ip += processed;
}
