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

It's an example for LZMA + x86 Filter use.
You can use .lzma86 extension, if you write that stream to file.
.lzma86 header adds one additional byte to standard .lzma header.
.lzma86 header (14 bytes):
Offset Size Description
0 1 = 0 - no filter, pure LZMA
= 1 - x86 filter + LZMA
1 1 lc, lp and pb in encoded form
2 4 dictSize (little endian)
6 8 uncompressed size (little endian)
Lzma86_Encode
-------------
level - compression level: 0 <= level <= 9, the default value for "level" is 5.
dictSize - The dictionary size in bytes. The maximum value is
128 MB = (1 << 27) bytes for 32-bit version
1 GB = (1 << 30) bytes for 64-bit version
The default value is 16 MB = (1 << 24) bytes, for level = 5.
It's recommended to use the dictionary that is larger than 4 KB and
that can be calculated as (1 << N) or (3 << N) sizes.
For better compression ratio dictSize must be >= inSize.
filterMode:
SZ_FILTER_NO - no Filter
SZ_FILTER_YES - x86 Filter
SZ_FILTER_AUTO - it tries both alternatives to select best.
Encoder will use 2 or 3 passes:
2 passes when FILTER_NO provides better compression.
3 passes when FILTER_YES provides better compression.
Lzma86Encode allocates Data with MyAlloc functions.
RAM Requirements for compressing:
RamSize = dictionarySize * 11.5 + 6MB + FilterBlockSize
filterMode FilterBlockSize
SZ_FILTER_NO 0
SZ_FILTER_YES inSize
SZ_FILTER_AUTO inSize
Return code:
SZ_OK - OK
SZ_ERROR_MEM - Memory allocation error
SZ_ERROR_PARAM - Incorrect paramater
SZ_ERROR_OUTPUT_EOF - output buffer overflow
SZ_ERROR_THREAD - errors in multithreading functions (only for Mt version)

In: the pointer to the size of outProps buffer; *outPropsSize = LZMA_PROPS_SIZE = 5.
Out: the pointer to the size of written properties in outProps buffer; *outPropsSize = LZMA_PROPS_SIZE = 5.
LZMA Encoder will use defult values for any parameter, if it is

0: 16 KB 0 32

2: 256 KB 0 32
3: 1 MB 0 32
4: 4 MB 0 32
5: 16 MB 1 32
6: 32 MB 1 32
7+: 64 MB 1 64
The default value for "level" is 5.
algo = 0 means fast method
algo = 1 means normal method
dictSize - The dictionary size in bytes. The maximum value is
128 MB = (1 << 27) bytes for 32-bit version
1 GB = (1 << 30) bytes for 64-bit version
The default value is 16 MB = (1 << 24) bytes.
It's recommended to use the dictionary that is larger than 4 KB and
that can be calculated as (1 << N) or (3 << N) sizes.
lc - The number of literal context bits (high bits of previous literal).
It can be in the range from 0 to 8. The default value is 3.
Sometimes lc=4 gives the gain for big files.
lp - The number of literal pos bits (low bits of current position for literals).
It can be in the range from 0 to 4. The default value is 0.
The lp switch is intended for periodical data when the period is equal to 2^lp.
For example, for 32-bit (4 bytes) periodical data you can use lp=2. Often it's
better to set lc=0, if you change lp switch.
pb - The number of pos bits (low bits of current position).
It can be in the range from 0 to 4. The default value is 2.
The pb switch is intended for periodical data when the period is equal 2^pb.
fb - Word size (the number of fast bytes).
It can be in the range from 5 to 273. The default value is 32.
Usually, a big number gives a little bit better compression ratio and
slower compression process.
numThreads - The number of thereads. 1 or 2. The default value is 2.
Fast mode (algo = 0) can use only 1 thread.
Out:
destLen - processed output size
Returns:
SZ_OK - OK
SZ_ERROR_MEM - Memory allocation error
SZ_ERROR_PARAM - Incorrect paramater
SZ_ERROR_OUTPUT_EOF - output buffer overflow
SZ_ERROR_THREAD - errors in multithreading functions (only for Mt version)

finishMode:
It has meaning only if the decoding reaches output limit (*destLen).

CODER_FINISH_END - read EndOfStream marker after decoding
Returns:
SZ_OK
status:
CODER_STATUS_NOT_FINISHED,
CODER_STATUS_NEEDS_MORE_INPUT - maybe there are more xz streams,
call XzUnpacker_IsStreamWasFinished to check that current stream was finished
SZ_ERROR_MEM - Memory allocation error
SZ_ERROR_DATA - Data error
SZ_ERROR_UNSUPPORTED - Unsupported method or method properties
SZ_ERROR_CRC - CRC error
// SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
SZ_ERROR_NO_ARCHIVE - the error with xz Stream Header with one of the following reasons:
- xz Stream Signature failure
- CRC32 of xz Stream Header is failed
- The size of Stream padding is not multiple of four bytes.
It's possible to get that error, if xz stream was finished and the stream
contains some another data. In that case you can call XzUnpacker_GetExtraSize()
function to get real size of xz stream.
