BCJ2 encoder uses ip/fileIp/fileSize/relatLimit values to calculate RC symbol.

/*
We can use 2 alternative versions of code:
1) non-marker version:
Byte CBcj2Enc::context
Byte temp[8];
Last byte of marker (e8/e9/[0f]8x) can be written to temp[] buffer.
Encoder writes last byte of marker (e8/e9/[0f]8x) to dest, only in conjunction
with writing branch symbol to range coder in same Bcj2Enc_Encode_2() call.
2) marker version:
UInt32 CBcj2Enc::context
Byte CBcj2Enc::temp[4];
MARKER_FLAG in CBcj2Enc::context shows that CBcj2Enc::context contains finded marker.
it's allowed that
one call of Bcj2Enc_Encode_2() writes last byte of marker (e8/e9/[0f]8x) to dest,
and another call of Bcj2Enc_Encode_2() does offset conversion.
So different values of (fileIp) and (fileSize) are possible
in these different Bcj2Enc_Encode_2() calls.
Also marker version requires additional if((v & MARKER_FLAG) == 0) check in main loop.
So we use non-marker version.
*/
/*
Corner cases with overlap in multi-block.
before v23: there was one corner case, where converted instruction
could start in one sub-stream and finish in next sub-stream.
If multi-block (solid) encoding is used,
and BCJ2_ENC_FINISH_MODE_END_BLOCK is used for each sub-stream.
and (0f) is last byte of previous sub-stream
and (8x) is first byte of current sub-stream
then (0f 8x) pair is treated as marker by BCJ2 encoder and decoder.
BCJ2 encoder can converts 32-bit offset for that (0f 8x) cortage,
if that offset meets limit requirements.
If encoder allows 32-bit offset conversion for such overlap case,
then the data in 3 uncompressed BCJ2 streams for some sub-stream
can depend from data of previous sub-stream.
That corner case is not big problem, and it's rare case.
Since v23.00 we do additional check to prevent conversions in such overlap cases.

/*
These functions convert data that contain CPU instructions.
Each such function converts relative addresses to absolute addresses in some
branch instructions: CALL (in all converters) and JUMP (X86 converter only).
Such conversion allows to increase compression ratio, if we compress that data.
There are 2 types of converters:
Byte * Conv_RISC (Byte *data, SizeT size, UInt32 pc);
Byte * ConvSt_X86(Byte *data, SizeT size, UInt32 pc, UInt32 *state);
Each Converter supports 2 versions: one for encoding
and one for decoding (_Enc/_Dec postfixes in function name).
In params:
data : data buffer
size : size of data
pc : current virtual Program Counter (Instruction Pinter) value
In/Out param:
state : pointer to state variable (for X86 converter only)
Return:
The pointer to position in (data) buffer after last byte that was processed.
If the caller calls converter again, it must call it starting with that position.
But the caller is allowed to move data in buffer. so pointer to
current processed position also will be changed for next call.
Also the caller must increase internal (pc) value for next call.
Each converter has some characteristics: Endian, Alignment, LookAhead.
Type Endian Alignment LookAhead
X86 little 1 4
ARMT little 2 2
ARM little 4 0
ARM64 little 4 0
PPC big 4 0
SPARC big 4 0
IA64 little 16 0
(data) must be aligned for (Alignment).
processed size can be calculated as:
SizeT processed = Conv(data, size, pc) - data;
if (processed == 0)
it means that converter needs more data for processing.
If (size < Alignment + LookAhead)
then (processed == 0) is allowed.
Example code for conversion in loop:
UInt32 pc = 0;
size = 0;
for (;;)
{
size += Load_more_input_data(data + size);
SizeT processed = Conv(data, size, pc) - data;
if (processed == 0 && no_more_input_data_after_size)
break; // we stop convert loop
data += processed;
size -= processed;
pc += processed;
}

GCC:
2007: it preserved ebx for (__PIC__ && __i386__)

CLANG:
2014+: it preserves rbx, but only for 64-bit code. No __PIC__ check.
Why CLANG cares about 64-bit mode only, and doesn't care about ebx (in 32-bit)?
Do we need __PIC__ test for CLANG or we must care about rbx even if

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)

outPropsSize -
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
-1 for any from: level, loc, lp, pb, fb, numThreads
0 for dictSize
level - compression level: 0 <= level <= 9;
level dictSize algo fb
0: 64 KB 0 32
1: 256 KB 0 32
2: 1 MB 0 32
3: 4 MB 0 32
4: 16 MB 0 32
5: 16 MB 1 32
6: 32 MB 1 32
7: 32 MB 1 64
8: 64 MB 1 64
9: 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.
In:
dest - output data buffer
destLen - output data buffer size
src - input data
srcLen - input data size
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)

PPMD code can write full CPpmd_State structure data to CPpmd*_Context

If we use pointers to different types, but that point to shared
memory space, we can have aliasing problem (strict aliasing).
XLC compiler in -O2 mode can change the order of memory write instructions
in relation to read instructions, if we have use pointers to different types.
To solve that aliasing problem we use combined CPpmd*_Context structure
with unions that contain the fields from both structures:
the original CPpmd*_Context and CPpmd_State.
So we can access the fields from both structures via one pointer,
and the compiler doesn't change the order of write instructions
in relation to read instructions.
If we don't use memory write instructions to shared memory in
some local code, and we use only reading instructions (read only),
then probably it's safe to use pointers to different types for reading.

the root function of thread doesn't set 16-byte alignment.

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

Returns:
SZ_OK
status:
CODER_STATUS_NOT_FINISHED,
CODER_STATUS_NEEDS_MORE_INPUT - the decoder can return it in two cases:
1) it needs more input data to finish current xz stream
2) xz stream was finished successfully. But the decoder supports multiple
concatented xz streams. So it expects more input data for new xz streams.
Call XzUnpacker_IsStreamWasFinished() to check that latest xz stream was finished successfully.
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.
