__cpuid (function == 4) requires subfunction number in ECX.
MSDN: The __cpuid intrinsic clears the ECX register before calling the cpuid instruction.
__cpuid() in new MSVC clears ECX.
__cpuid() in old MSVC (14.00) doesn't clear ECX
We still can use __cpuid for low (function) values that don't require ECX,
but __cpuid() in old MSVC will be incorrect for some function values: (function == 4).
So here we use the hack for old MSVC to send (subFunction) in ECX register to cpuid instruction,
where ECX value is first parameter for FAST_CALL / NO_INLINE function,
So the caller of MY__cpuidex_HACK() sets ECX as subFunction, and
old MSVC for __cpuid() doesn't change ECX and cpuid instruction gets (subFunction) value.

LzmaDec_TryDummy() was called before to exclude LITERAL and MATCH-REP cases.

is not END_OF_PAYALOAD_MARKER, then the function doesn't write any byte to dictionary,

The first LZMA symbol will be decoded in any case.
All main checks for limits are at the end of main loop,
It decodes additional LZMA-symbols while (p->buf < bufLimit && dicPos < limit),
RangeCoder is still without last normalization when (p->buf < bufLimit) is being checked.
But if (p->buf < bufLimit), the caller provided at least (LZMA_REQUIRED_INPUT_MAX + 1) bytes for
next iteration before limit (bufLimit + LZMA_REQUIRED_INPUT_MAX),
that is enough for worst case LZMA symbol with one additional RangeCoder normalization for one bit.
So that function never reads bufLimit [LZMA_REQUIRED_INPUT_MAX] byte.
Out:
RangeCoder is normalized

LZMA supports optional end_marker.
So the decoder can lookahead for one additional LZMA-Symbol to check end_marker.
That additional LZMA-Symbol can require up to LZMA_REQUIRED_INPUT_MAX bytes in input stream.
When the decoder reaches dicLimit, it looks (finishMode) parameter:
if (finishMode == LZMA_FINISH_ANY), the decoder doesn't lookahead
if (finishMode != LZMA_FINISH_ANY), the decoder lookahead, if end_marker is possible for current position
When the decoder lookahead, and the lookahead symbol is not end_marker, we have two ways:
1) Strict mode (default) : the decoder returns SZ_ERROR_DATA.
2) The relaxed mode (alternative mode) : we could return SZ_OK, and the caller
must check (status) value. The caller can show the error,
if the end of stream is expected, and the (status) is noit
LZMA_STATUS_FINISHED_WITH_MARK or LZMA_STATUS_MAYBE_FINISHED_WITHOUT_MARK.

PPMD code can write full CPpmd_State structure data to CPpmd*_Context
at (byte offset = 2) instead of some fields of original CPpmd*_Context structure.
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.

HISTORY of the LZMA SDK
-----------------------
21.07 2021-12-26
-------------------------
- New switches: -spm and -im!{file_path} to exclude directories from processing
for specified paths that don't contain path separator character at the end of path.
- The sorting order of files in archives was slightly changed to be more consistent
for cases where the name of some directory is the same as the prefix part of the name
of another directory or file.
21.06 2021-11-24
-------------------------
- Bug in LZMA encoder in file LzmaEnc.c was fixed:
LzmaEnc_MemEncode(), LzmaEncode() and LzmaCompress() could work incorrectly,
if size value for output buffer is smaller than size required for all compressed data.
LzmaEnc_Encode() could work incorrectly,
if callback ISeqOutStream::Write() doesn't write all compressed data.
NCompress::NLzma::CEncoder::Code() could work incorrectly,
if callback ISequentialOutStream::Write() returns error code.
- Bug in versions 21.00-21.05 was fixed:
7-Zip didn't set attributes of directories during archive extracting.
21.04 beta 2021-11-02
-------------------------
- 7-Zip now reduces the number of working CPU threads for compression,
if RAM size is not enough for compression with big LZMA2 dictionary.
- 7-Zip now can create and check "file.sha256" text files that contain the list
of file names and SHA-256 checksums in format compatible with sha256sum program.
21.03 beta 2021-07-20
-------------------------
- The maximum dictionary size for LZMA/LZMA2 compressing was increased to 4 GB (3840 MiB).
- Minor speed optimizations in LZMA/LZMA2 compressing.
21.02 alpha 2021-05-06
-------------------------
- The command line version of 7-Zip for macOS was released.
- The speed for LZMA and LZMA2 decompression in arm64 versions for macOS and Linux
was increased by 20%-60%.
21.01 alpha 2021-03-09
-------------------------
- The command line version of 7-Zip for Linux was released.
- The improvements for speed of ARM64 version using hardware CPU instructions
for AES, CRC-32, SHA-1 and SHA-256.
- Some bugs were fixed.
20.02 alpha 2020-08-08
-------------------------
- The default number of LZMA2 chunks per solid block in 7z archive was increased to 64.
It allows to increase the compression speed for big 7z archives, if there is a big number
of CPU cores and threads.
- The speed of PPMd compressing/decompressing was increased for 7z archives.
- The new -ssp switch. If the switch -ssp is specified, 7-Zip doesn't allow the system
to modify "Last Access Time" property of source files for archiving and hashing operations.
- Some bugs were fixed.
20.00 alpha 2020-02-06
-------------------------
- 7-Zip now supports new optional match finders for LZMA/LZMA2 compression: bt5 and hc5,
that can work faster than bt4 and hc4 match finders for the data with big redundancy.
- The compression ratio was improved for Fast and Fastest compression levels with the
following default settings:
- Fastest level (-mx1) : hc5 match finder with 256 KB dictionary.
- Fast level (-mx3) : hc5 match finder with 4 MB dictionary.
- Minor speed optimizations in multithreaded LZMA/LZMA2 compression for Normal/Maximum/Ultra
compression levels.
19.00 2019-02-21
-------------------------
- Encryption strength for 7z archives was increased:

UNIX/Linux version
------------------
To compile C++ version of file->file LZMA encoding, go to directory
CPP/7zip/Bundles/LzmaCon
and call make to recompile it:
make -f makefile.gcc clean all
There are several otpions to compile 7-Zip with different compilers: gcc and clang.
Also 7-Zip code contains two versions for some critical parts of code: in C and in Assembeler.
So if you compile the version with Assembeler code, you will get faster 7-Zip binary.
7-Zip's assembler code uses the following syntax for different platforms:
1) x86 and x86-64 (AMD64): MASM syntax.
There are 2 programs that supports MASM syntax in Linux.
' 'Asmc Macro Assembler and JWasm. But JWasm now doesn't support some
cpu instructions used in 7-Zip.
So you must install Asmc Macro Assembler in Linux, if you want to compile fastest version
of 7-Zip x86 and x86-64:
https://github.com/nidud/asmc
2) arm64: GNU assembler for ARM64 with preprocessor.
That systax of that arm64 assembler code in 7-Zip is supported by GCC and CLANG for ARM64.
There are different binaries that can be compiled from 7-Zip source.
There are 2 main files in folder for compiling:
makefile - that can be used for compiling Windows version of 7-Zip with nmake command
makefile.gcc - that can be used for compiling Linux/macOS versions of 7-Zip with make command
At first you must change the current folder to folder that contains `makefile.gcc`:
cd CPP/7zip/Bundles/Alone7z
Then you can compile `makefile.gcc` with the command:
make -j -f makefile.gcc
Also there are additional "*.mak" files in folder "CPP/7zip/" that can be used to compile
7-Zip binaries with optimized code and optimzing options.
To compile with GCC without assembler:
cd CPP/7zip/Bundles/Alone7z
make -j -f ../../cmpl_gcc.mak
To compile with CLANG without assembler:
make -j -f ../../cmpl_clang.mak
To compile 7-Zip for x86-64 with asmc assembler:
make -j -f ../../cmpl_gcc_x64.mak
To compile 7-Zip for arm64 with assembler:
make -j -f ../../cmpl_gcc_arm64.mak
To compile 7-Zip for arm64 for macOS:
make -j -f ../../cmpl_mac_arm64.mak
Also you can change some compiler options in the mak files:
cmpl_gcc.mak
var_gcc.mak
warn_gcc.mak
In some UNIX/Linux versions you must compile LZMA with static libraries.
To compile with static libraries, you can use
LIB = -lm -static
Also you can use p7zip (port of 7-Zip for POSIX systems like Unix or Linux):
