External: update LZMA SDK to latest version
Update from version 4.65 (2009) to latest 23.01 (2023). LZMA is only used for pointcache "Heavy" compression option. With updated SDK, testing in a 100k particle system point cache (Windows/Ryzen5950X), average times to read or write a cached frame: - Read a bit faster, 24.3 -> 23.2ms - Write/bake about 2x faster, 237 -> 103ms Pull Request: https://projects.blender.org/blender/blender/pulls/118433

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)?

_xgetbv() is macro that works via __builtin_ia32_xgetbv()

inlined to function that has no __target__("xsave") attribute.

If we want _xgetbv() call inlining, then we should use asm version

LZMA SDK 4.65
|
||||
-------------
|
||||
|
||||
LZMA SDK provides the documentation, samples, header files, libraries,
|
||||
and tools you need to develop applications that use LZMA compression.
|
||||
|
||||
LZMA is default and general compression method of 7z format
|
||||
in 7-Zip compression program (www.7-zip.org). LZMA provides high
|
||||
compression ratio and very fast decompression.
|
||||
|
||||
LZMA is an improved version of famous LZ77 compression algorithm.
|
||||
It was improved in way of maximum increasing of compression ratio,
|
||||
keeping high decompression speed and low memory requirements for
|
||||
decompressing.

- Compiled file->file LZMA compressing/decompressing program for Windows system
|
||||
|
||||
|
||||
UNIX/Linux version
|
||||
------------------
|
||||
To compile C++ version of file->file LZMA encoding, go to directory
|
||||
C++/7zip/Compress/LZMA_Alone
|
||||
and call make to recompile it:
|
||||
make -f makefile.gcc clean all

||||
LZMA features
|
||||
-------------
|
||||
- Variable dictionary size (up to 1 GB)
|
||||
- Estimated compressing speed: about 2 MB/s on 2 GHz CPU
|
||||
- Estimated decompressing speed:
|
||||
- 20-30 MB/s on 2 GHz Core 2 or AMD Athlon 64
|
||||
- 1-2 MB/s on 200 MHz ARM, MIPS, PowerPC or other simple RISC
|
||||
- Small memory requirements for decompressing (16 KB + DictionarySize)
|
||||
- Small code size for decompressing: 5-8 KB
|
||||
|
||||
LZMA decoder uses only integer operations and can be
|
||||
implemented in any modern 32-bit CPU (or on 16-bit CPU with some conditions).
|
||||
|
||||
Some critical operations that affect the speed of LZMA decompression:
|
||||
1) 32*16 bit integer multiply
|
||||
2) Misspredicted branches (penalty mostly depends from pipeline length)
|
||||
3) 32-bit shift and arithmetic operations
|
||||
|
||||
The speed of LZMA decompressing mostly depends from CPU speed.
|
||||
Memory speed has no big meaning. But if your CPU has small data cache,
|
||||
overall weight of memory speed will slightly increase.
|
||||
|
||||
|
||||
How To Use
|
||||
----------
|
||||
|
||||
Using LZMA encoder/decoder executable
|
||||
--------------------------------------
|
||||
|
||||
Usage: LZMA <e|d> inputFile outputFile [<switches>...]
|
||||
|
||||
e: encode file
|
||||
|
||||
d: decode file
|
||||
|
||||
b: Benchmark. There are two tests: compressing and decompressing
|
||||
with LZMA method. Benchmark shows rating in MIPS (million
|
||||
instructions per second). Rating value is calculated from
|
||||
measured speed and it is normalized with Intel's Core 2 results.
|
||||
Also Benchmark checks possible hardware errors (RAM
|
||||
errors in most cases). Benchmark uses these settings:
|
||||
(-a1, -d21, -fb32, -mfbt4). You can change only -d parameter.
|
||||
Also you can change the number of iterations. Example for 30 iterations:
|
||||
LZMA b 30
|
||||
Default number of iterations is 10.
|
||||
|
||||
<Switches>
|
||||
|
||||
|
||||
-a{N}: set compression mode 0 = fast, 1 = normal
|
||||
default: 1 (normal)
|
||||
|
||||
d{N}: Sets Dictionary size - [0, 30], default: 23 (8MB)
|
||||
The maximum value for dictionary size is 1 GB = 2^30 bytes.
|
||||
Dictionary size is calculated as DictionarySize = 2^N bytes.
|
||||
For decompressing file compressed by LZMA method with dictionary
|
||||
size D = 2^N you need about D bytes of memory (RAM).
|
||||
|
||||
-fb{N}: set number of fast bytes - [5, 273], default: 128
|
||||
Usually big number gives a little bit better compression ratio
|
||||
and slower compression process.
|
||||
|
||||
-lc{N}: set number of literal context bits - [0, 8], default: 3
|
||||
Sometimes lc=4 gives gain for big files.
|
||||
|
||||
-lp{N}: set number of literal pos bits - [0, 4], default: 0
|
||||
lp switch is intended for periodical data when period is
|
||||
equal 2^N. For example, for 32-bit (4 bytes)
|
||||
periodical data you can use lp=2. Often it's better to set lc0,
|
||||
if you change lp switch.
|
||||
|
||||
-pb{N}: set number of pos bits - [0, 4], default: 2
|
||||
pb switch is intended for periodical data
|
||||
when period is equal 2^N.
|
||||
|
||||
-mf{MF_ID}: set Match Finder. Default: bt4.
|
||||
Algorithms from hc* group doesn't provide good compression
|
||||
ratio, but they often works pretty fast in combination with
|
||||
fast mode (-a0).
|
||||
|
||||
Memory requirements depend from dictionary size
|
||||
(parameter "d" in table below).
|
||||
|
||||
MF_ID Memory Description
|
||||
|
||||
bt2 d * 9.5 + 4MB Binary Tree with 2 bytes hashing.
|
||||
bt3 d * 11.5 + 4MB Binary Tree with 3 bytes hashing.
|
||||
bt4 d * 11.5 + 4MB Binary Tree with 4 bytes hashing.
|
||||
hc4 d * 7.5 + 4MB Hash Chain with 4 bytes hashing.
|
||||
|
||||
-eos: write End Of Stream marker. By default LZMA doesn't write
|
||||
eos marker, since LZMA decoder knows uncompressed size
|
||||
stored in .lzma file header.
|
||||
|
||||
-si: Read data from stdin (it will write End Of Stream marker).
|
||||
-so: Write data to stdout
|
||||
|
||||
|
||||
Examples:
|
||||
|
||||
1) LZMA e file.bin file.lzma -d16 -lc0
|
||||
|
||||
compresses file.bin to file.lzma with 64 KB dictionary (2^16=64K)
|
||||
and 0 literal context bits. -lc0 allows to reduce memory requirements
|
||||
for decompression.
|
||||
|
||||
|
||||
2) LZMA e file.bin file.lzma -lc0 -lp2
|
||||
|
||||
compresses file.bin to file.lzma with settings suitable
|
||||
for 32-bit periodical data (for example, ARM or MIPS code).
|
||||
|
||||
3) LZMA d file.lzma file.bin
|
||||
|
||||
decompresses file.lzma to file.bin.
|
||||

||||
|
||||
Compression ratio hints
|
||||
-----------------------
|
||||
|
||||
Recommendations
|
||||
---------------
|
||||
|
||||
To increase the compression ratio for LZMA compressing it's desirable
|
||||
to have aligned data (if it's possible) and also it's desirable to locate
|
||||
data in such order, where code is grouped in one place and data is
|
||||
grouped in other place (it's better than such mixing: code, data, code,
|
||||
data, ...).
|
||||
|
||||
|
||||
Filters
|
||||
-------
|
||||
You can increase the compression ratio for some data types, using
|
||||
special filters before compressing. For example, it's possible to
|
||||
increase the compression ratio on 5-10% for code for those CPU ISAs:
|
||||
x86, IA-64, ARM, ARM-Thumb, PowerPC, SPARC.
|
||||
|
||||
You can find C source code of such filters in C/Bra*.* files
|
||||
|
||||
You can check the compression ratio gain of these filters with such
|
||||
7-Zip commands (example for ARM code):
|
||||
No filter:
|
||||
7z a a1.7z a.bin -m0=lzma
|
||||
|
||||
With filter for little-endian ARM code:
|
||||
7z a a2.7z a.bin -m0=arm -m1=lzma
|
||||
|
||||
It works in such manner:
|
||||
Compressing = Filter_encoding + LZMA_encoding
|
||||
Decompressing = LZMA_decoding + Filter_decoding
|
||||
|
||||
Compressing and decompressing speed of such filters is very high,
|
||||
so it will not increase decompressing time too much.
|
||||
Moreover, it reduces decompression time for LZMA_decoding,
|
||||
since compression ratio with filtering is higher.
|
||||
|
||||
These filters convert CALL (calling procedure) instructions
|
||||
from relative offsets to absolute addresses, so such data becomes more
|
||||
compressible.
|
||||
|
||||
For some ISAs (for example, for MIPS) it's impossible to get gain from such filter.
|
||||
|
||||
|
||||
LZMA compressed file format
|
||||
---------------------------
|
||||
Offset Size Description
|
||||
0 1 Special LZMA properties (lc,lp, pb in encoded form)
|
||||
1 4 Dictionary size (little endian)
|
||||
5 8 Uncompressed size (little endian). -1 means unknown size
|
||||
13 Compressed data

|
||||
ANSI-C LZMA Decoder
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Please note that interfaces for ANSI-C code were changed in LZMA SDK 4.58.
|
||||
If you want to use old interfaces you can download previous version of LZMA SDK
|
||||
from sourceforge.net site.
|
||||
|
||||
To use ANSI-C LZMA Decoder you need the following files:
|
||||
1) LzmaDec.h + LzmaDec.c + Types.h
|
||||
LzmaUtil/LzmaUtil.c is example application that uses these files.
|
||||
|
||||
|
||||
Memory requirements for LZMA decoding
|
||||
-------------------------------------
|
||||
|
||||
Stack usage of LZMA decoding function for local variables is not
|
||||
larger than 200-400 bytes.
|
||||
|
||||
LZMA Decoder uses dictionary buffer and internal state structure.
|
||||
Internal state structure consumes
|
||||
state_size = (4 + (1.5 << (lc + lp))) KB
|
||||
by default (lc=3, lp=0), state_size = 16 KB.
|
||||
|
||||
|
||||
How To decompress data
|
||||
----------------------
|
||||
|
||||
LZMA Decoder (ANSI-C version) now supports 2 interfaces:
|
||||
1) Single-call Decompressing
|
||||
2) Multi-call State Decompressing (zlib-like interface)
|
||||
|
||||
You must use external allocator:
|
||||
Example:
|
||||
void *SzAlloc(void *p, size_t size) { p = p; return malloc(size); }
|
||||
void SzFree(void *p, void *address) { p = p; free(address); }
|
||||
ISzAlloc alloc = { SzAlloc, SzFree };
|
||||
|
||||
You can use p = p; operator to disable compiler warnings.
|
||||
|
||||
|
||||
Single-call Decompressing
|
||||
-------------------------
|
||||
When to use: RAM->RAM decompressing
|
||||
Compile files: LzmaDec.h + LzmaDec.c + Types.h
|
||||
Compile defines: no defines
|
||||
Memory Requirements:
|
||||
- Input buffer: compressed size
|
||||
- Output buffer: uncompressed size
|
||||
- LZMA Internal Structures: state_size (16 KB for default settings)
|
||||
|
||||
Interface:
|
||||
int LzmaDecode(Byte *dest, SizeT *destLen, const Byte *src, SizeT *srcLen,
|
||||
const Byte *propData, unsigned propSize, ELzmaFinishMode finishMode,
|
||||
ELzmaStatus *status, ISzAlloc *alloc);
|
||||
In:
|
||||
dest - output data
|
||||
destLen - output data size
|
||||
src - input data
|
||||
srcLen - input data size
|
||||
propData - LZMA properties (5 bytes)
|
||||
propSize - size of propData buffer (5 bytes)
|
||||
finishMode - It has meaning only if the decoding reaches output limit (*destLen).
|
||||
LZMA_FINISH_ANY - Decode just destLen bytes.
|
||||
LZMA_FINISH_END - Stream must be finished after (*destLen).
|
||||
You can use LZMA_FINISH_END, when you know that
|
||||
current output buffer covers last bytes of stream.
|
||||
alloc - Memory allocator.
|
||||
|
||||
Out:
|
||||
destLen - processed output size
|
||||
srcLen - processed input size
|
||||
|
||||
Output:
|
||||
SZ_OK
|
||||
status:
|
||||
LZMA_STATUS_FINISHED_WITH_MARK
|
||||
LZMA_STATUS_NOT_FINISHED
|
||||
LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK
|
||||
SZ_ERROR_DATA - Data error
|
||||
SZ_ERROR_MEM - Memory allocation error
|
||||
SZ_ERROR_UNSUPPORTED - Unsupported properties
|
||||
SZ_ERROR_INPUT_EOF - It needs more bytes in input buffer (src).
|
||||
|
||||
If LZMA decoder sees end_marker before reaching output limit, it returns OK result,
|
||||
and output value of destLen will be less than output buffer size limit.
|
||||
|
||||
You can use multiple checks to test data integrity after full decompression:
|
||||
1) Check Result and "status" variable.
|
||||
2) Check that output(destLen) = uncompressedSize, if you know real uncompressedSize.
|
||||
3) Check that output(srcLen) = compressedSize, if you know real compressedSize.
|
||||
You must use correct finish mode in that case. */
|
||||
|
||||
|
||||
Multi-call State Decompressing (zlib-like interface)
|
||||
----------------------------------------------------
|
||||
|
||||
When to use: file->file decompressing
|
||||
Compile files: LzmaDec.h + LzmaDec.c + Types.h
|
||||
|
||||
Memory Requirements:
|
||||
- Buffer for input stream: any size (for example, 16 KB)
|
||||
- Buffer for output stream: any size (for example, 16 KB)
|
||||
- LZMA Internal Structures: state_size (16 KB for default settings)
|
||||
- LZMA dictionary (dictionary size is encoded in LZMA properties header)
|
||||
|
||||
1) read LZMA properties (5 bytes) and uncompressed size (8 bytes, little-endian) to header:
|
||||
unsigned char header[LZMA_PROPS_SIZE + 8];
|
||||
ReadFile(inFile, header, sizeof(header)
|
||||
|
||||
2) Allocate CLzmaDec structures (state + dictionary) using LZMA properties
|
||||
|
||||
CLzmaDec state;
|
||||
LzmaDec_Constr(&state);
|
||||
res = LzmaDec_Allocate(&state, header, LZMA_PROPS_SIZE, &g_Alloc);
|
||||
if (res != SZ_OK)
|
||||
return res;
|
||||
|
||||
3) Init LzmaDec structure before any new LZMA stream. And call LzmaDec_DecodeToBuf in loop
|
||||
|
||||
LzmaDec_Init(&state);
|
||||
for (;;)
|
||||
{
|
||||
...
|
||||
int res = LzmaDec_DecodeToBuf(CLzmaDec *p, Byte *dest, SizeT *destLen,
|
||||
const Byte *src, SizeT *srcLen, ELzmaFinishMode finishMode);
|
||||
...
|
||||
}
|
||||
|
||||
|
||||
4) Free all allocated structures
|
||||
LzmaDec_Free(&state, &g_Alloc);
|
||||
|
||||
For full code example, look at C/LzmaUtil/LzmaUtil.c code.
|
||||
|
||||
|
||||
How To compress data
|
||||
--------------------
|
||||
|
||||
Compile files: LzmaEnc.h + LzmaEnc.c + Types.h +
|
||||
LzFind.c + LzFind.h + LzFindMt.c + LzFindMt.h + LzHash.h
|
||||
|
||||
Memory Requirements:
|
||||
- (dictSize * 11.5 + 6 MB) + state_size
|
||||
|
||||
Lzma Encoder can use two memory allocators:
|
||||
1) alloc - for small arrays.
|
||||
2) allocBig - for big arrays.
|
||||
|
||||
For example, you can use Large RAM Pages (2 MB) in allocBig allocator for
|
||||
better compression speed. Note that Windows has bad implementation for
|
||||
Large RAM Pages.
|
||||
It's OK to use same allocator for alloc and allocBig.
|
||||
|
||||
|
||||
Single-call Compression with callbacks
|
||||
--------------------------------------
|
||||
|
||||
Check C/LzmaUtil/LzmaUtil.c as example,
|
||||
|
||||
When to use: file->file decompressing
|
||||
|
||||
1) you must implement callback structures for interfaces:
|
||||
ISeqInStream
|
||||
ISeqOutStream
|
||||
ICompressProgress
|
||||
ISzAlloc
|
||||
|
||||
static void *SzAlloc(void *p, size_t size) { p = p; return MyAlloc(size); }
|
||||
static void SzFree(void *p, void *address) { p = p; MyFree(address); }
|
||||
static ISzAlloc g_Alloc = { SzAlloc, SzFree };
|
||||
|
||||
CFileSeqInStream inStream;
|
||||
CFileSeqOutStream outStream;
|
||||
|
||||
inStream.funcTable.Read = MyRead;
|
||||
inStream.file = inFile;
|
||||
outStream.funcTable.Write = MyWrite;
|
||||
outStream.file = outFile;
|
||||
|
||||
|
||||
2) Create CLzmaEncHandle object;
|
||||
|
||||
CLzmaEncHandle enc;
|
||||
|
||||
enc = LzmaEnc_Create(&g_Alloc);
|
||||
if (enc == 0)
|
||||
return SZ_ERROR_MEM;
|
||||
|
||||
|
||||
3) initialize CLzmaEncProps properties;
|
||||
|
||||
LzmaEncProps_Init(&props);
|
||||
|
||||
Then you can change some properties in that structure.
|
||||
|
||||
4) Send LZMA properties to LZMA Encoder
|
||||
|
||||
res = LzmaEnc_SetProps(enc, &props);
|
||||
|
||||
5) Write encoded properties to header
|
||||
|
||||
Byte header[LZMA_PROPS_SIZE + 8];
|
||||
size_t headerSize = LZMA_PROPS_SIZE;
|
||||
UInt64 fileSize;
|
||||
int i;
|
||||
|
||||
res = LzmaEnc_WriteProperties(enc, header, &headerSize);
|
||||
fileSize = MyGetFileLength(inFile);
|
||||
for (i = 0; i < 8; i++)
|
||||
header[headerSize++] = (Byte)(fileSize >> (8 * i));
|
||||
MyWriteFileAndCheck(outFile, header, headerSize)
|
||||
|
||||
6) Call encoding function:
|
||||
res = LzmaEnc_Encode(enc, &outStream.funcTable, &inStream.funcTable,
|
||||
NULL, &g_Alloc, &g_Alloc);
|
||||
|
||||
7) Destroy LZMA Encoder Object
|
||||
LzmaEnc_Destroy(enc, &g_Alloc, &g_Alloc);
|
||||
|
||||
|
||||
If callback function return some error code, LzmaEnc_Encode also returns that code.
|
||||
|
||||
|
||||
Single-call RAM->RAM Compression
|
||||
--------------------------------
|
||||
|
||||
Single-call RAM->RAM Compression is similar to Compression with callbacks,
|
||||
but you provide pointers to buffers instead of pointers to stream callbacks:
|
||||
|
||||
HRes LzmaEncode(Byte *dest, SizeT *destLen, const Byte *src, SizeT srcLen,
|
||||
CLzmaEncProps *props, Byte *propsEncoded, SizeT *propsSize, int writeEndMark,
|
||||
ICompressProgress *progress, ISzAlloc *alloc, ISzAlloc *allocBig);
|
||||
|
||||
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)
|
||||
|
||||
|
||||
|
||||
LZMA Defines
|
||||
------------
|
||||
|
||||
_LZMA_SIZE_OPT - Enable some optimizations in LZMA Decoder to get smaller executable code.
|
||||
|
||||
_LZMA_PROB32 - It can increase the speed on some 32-bit CPUs, but memory usage for
|
||||
some structures will be doubled in that case.
|
||||
|
||||
_LZMA_UINT32_IS_ULONG - Define it if int is 16-bit on your compiler and long is 32-bit.
|
||||
|
||||
_LZMA_NO_SYSTEM_SIZE_T - Define it if you don't want to use size_t type.
|
||||
|
||||
|
||||
C++ LZMA Encoder/Decoder
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
C++ LZMA code use COM-like interfaces. So if you want to use it,
|
||||
you can study basics of COM/OLE.
|
||||
C++ LZMA code is just wrapper over ANSI-C code.
|
||||
|
||||
|
||||
C++ Notes
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
If you use some C++ code folders in 7-Zip (for example, C++ code for .7z handling),
|
||||
you must check that you correctly work with "new" operator.
|
||||
7-Zip can be compiled with MSVC 6.0 that doesn't throw "exception" from "new" operator.
|
||||
So 7-Zip uses "CPP\Common\NewHandler.cpp" that redefines "new" operator:
|
||||
operator new(size_t size)
|
||||
{
|
||||
void *p = ::malloc(size);
|
||||
if (p == 0)
|
||||
throw CNewException();
|
||||
return p;
|
||||
}
|
||||
If you use MSCV that throws exception for "new" operator, you can compile without
|
||||
"NewHandler.cpp". So standard exception will be used. Actually some code of
|
||||
7-Zip catches any exception in internal code and converts it to HRESULT code.
|
||||
So you don't need to catch CNewException, if you call COM interfaces of 7-Zip.
