2023-02-03liblzma: Fix typos in comments in string_conversion.c.Jia Tan1-2/+2
2023-02-03liblzma: Clarify block encoder and decoder documentation.Jia Tan1-4/+11
Added a few sentences to the description for lzma_block_encoder() and lzma_block_decoder() to highlight that the Block Header must be coded before calling these functions.
2023-02-03Update lzma_block documentation for lzma_block_uncomp_encode().Jia Tan1-0/+3

2023-02-03liblzma: Clarify comment in block.h.Jia Tan1-1/+2
2023-02-03liblzma: Improve documentation for block.h.Jia Tan1-21/+75
Standardizing each function to always specify params and return values. Output pointer parameters are also marked with doxygen style [out] to make it clear. Any note sections were also moved above the parameter and return sections for consistency.
2023-02-01liblzma: Clarify a comment about LZMA_STR_NO_VALIDATION.Jia Tan1-2/+3
The flag description for LZMA_STR_NO_VALIDATION was previously confusing about the treatment for filters than cannot be used with .xz format (lzma1) without using LZMA_STR_ALL_FILTERS. Now, it is clear that LZMA_STR_NO_VALIDATION is not a super set of LZMA_STR_ALL_FILTERS.
2023-02-01CI: Update .gitignore for artifacts directory in build-aux.Jia Tan1-0/+1
The workflow action for our CI pipeline can only reference artifacts in the source directory, so we should ignore these files if the ci_build.sh is run locally.

2023-01-27xz: Use clock_gettime() even if CLOCK_MONOTONIC isn't available.Lasse Collin2-5/+9
mythread.h and thus liblzma already does it.
2023-01-27po4a/po4a.conf: Sort the language identifiers in alphabetical order.Lasse Collin1-1/+1
2023-01-27xz: Add SIGTSTP handler for progress indicator time keeping.Lasse Collin4-2/+89
This way, if xz is stopped the elapsed time and estimated time remaining won't get confused by the amount of time spent in the stopped state. This raises SIGSTOP. It's not clear to me if this is the correct way. POSIX and glibc docs say that SIGTSTP shouldn't stop the process if it is orphaned but this commit doesn't attempt to handle that. Search for SIGTSTP in section 2.4.3: https://pubs.opengroup.org/onlinepubs/9699919799/functions/V2_chap02.html

2023-01-26Build: Avoid different quoting style in --enable-doxygen doc.Lasse Collin1-5/+5
2023-01-26tuklib_physmem: Check for __has_warning before GCC version.Lasse Collin1-3/+3
Clang can be configured to fake a too high GCC version so this way it's more robust.
2023-01-24liblzma: Fix documentation in filter.h for lzma_str_to_filters()Jia Tan1-1/+1
The previous documentation for lzma_str_to_filters() was technically correct, but misleading. lzma_str_to_filters() returns NULL on success, which is in practice always defined to 0. This is the same value as LZMA_OK, but lzma_str_to_filters() does not return lzma_ret so we should be more clear.
2023-01-24Revert "tuklib_common: Define __has_warning if it is not defined."Lasse Collin1-7/+0
This reverts commit 82e3c968bfa10e3ff13333bd9cbbadb5988d6766. Macros in the reserved namespace (_foo or __foo) shouldn't be #defined without a very good reason. Here the alternative would have been to #define tuklib_has_warning(str) to an approriate value. Also the tuklib_* files should stay namespace clean if possible.
2023-01-24tuklib_physmem: Clean up the way -Wcast-function-type is silenced on Windows.Lasse Collin1-4/+13
__has_warning and other __has_foo macros are meant to become compiler-agnostic so it's not good to check for __clang__ with it. This also relied on tuklib_common.h for #defining __has_warning which was confusing as #defining reserved macros is generally not a good idea.
2023-01-24xz: Flip the return value of suffix_is_set to match the documentation.Lasse Collin3-4/+5
Also edit style to match the existing coding style in the project.
2023-01-21xz: Refactor duplicated check for custom suffix when using --format=rawJia Tan3-18/+23
2023-01-21liblzma: Set documentation on all reserved fields to private.Jia Tan7-0/+173
This prevents the reserved fields from being part of the generated Doxygen documentation.
2023-01-20Doxygen: Update Doxyfile.in from 1.4.7 to 1.8.17.Jia Tan1-630/+1893
A few Doxygen tags were obsolete from 1.4.7. Version 1.8.17 released in 2019, so this should be compatible with resonable modern distros. The purpose of Doxygen these days is for docs on the website, so it doesn't necessarily have to work for everyone. Just when the maintainers want to update the docs.
2023-01-20Doxygen: Make Doxygen only produce liblzma API documentation by default.Jia Tan2-9/+48
Doxygen is now configurable in autotools only with --enable-doxygen=[api|all]. The default is "api", which will only generate HTML output for liblzma API functions. The LaTex documentation output was also disabled.
2023-01-20liblzma: Highlight liblzma API headers should not be included directly.Jia Tan14-28/+42
This improves the generated Doxygen HTML files to better highlight how to properly use the liblzma API header files.
2023-01-19tuklib_physmem: Silence warning from -Wcast-function-type on MinGW-w64.Jia Tan1-0/+9
tuklib_physmem depends on GetProcAddress() for both MSVC and MinGW-w64 to retrieve a function address. The proper way to do this is to cast the return value to the type of function pointer retrieved. Unfortunately, this causes a cast-function-type warning, so the best solution is to simply ignore the warning.
2023-01-19tuklib_common: Define __has_warning if it is not defined.Jia Tan1-0/+7
clang supports the __has_warning macro to determine if the version of clang compiling the code supports a given warning. If we do not define it for other compilers, it may cause a preprocessor error.
2023-01-18CI: Reorder 32-bit build first for Linux autotool builds.Jia Tan1-5/+12
The 32-bit build needs to be first so the configure cache only needs to be reset one time. The 32-bit build sets the CFLAGS env variable, so any build using that flag after will fail unless the cache is reset.
2023-01-18CI: Enable --config-cache in autotool builds.Jia Tan1-1/+1
If CFLAGS are set in a build, the cache must be cleared with "make distclean", or by deleting the cache file.
2023-01-16xz: Add missing comment for coder_set_compression_settings()Jia Tan1-1/+2
2023-01-16xz: Do not set compression settings with raw format in list mode.Jia Tan1-1/+2
Calling coder_set_compression_settings() in list mode with verbose mode on caused the filter chain and memory requirements to print. This was unnecessary since the command results in an error and not consistent with other formats like lzma and alone.
2023-01-13Translations: Update the Brazilian Portuguese translation.Jia Tan1-259/+344
2023-01-12CI: Disable shared and nls from various jobs in autotool runners.Jia Tan1-28/+28
Disabling shared library generation and linking should help speed up the runners. The shared library is still being tested in the 32 bit build and the full feature. Disabling nls is to check for any unexpected warnings or errors.
2023-01-12CI: Reorder the 32-bit job in the Ubuntu runner.Jia Tan1-5/+5
Run the 32 bit job sooner since this is a more interesting test than some of the later jobs.
2023-01-12CI: Allow disabling Native Language Support.Jia Tan1-1/+8
2023-01-12CI: Only run autogen.sh if it has not already run.Jia Tan1-3/+8
2023-01-12CI: Allow disabling shared library in autotools builds.Jia Tan1-1/+8
2023-01-12CI: Improve Usage readability and add -h option.Jia Tan1-2/+13
2023-01-12Build: Omit -Wmissing-noreturn from the default warnings.Lasse Collin1-1/+0
It's not that important. It can be annoying in builds that disable many features since in those cases the tests programs will correctly trigger this warning with Clang.
2023-01-12xz: Use ssize_t for the to-be-ignored return value from write(fd, ptr, 1).Lasse Collin1-1/+1
It makes no difference here as the return value fits into an int too and it then gets ignored but this looks better.
2023-01-12xz: Silence warnings from -Wsign-conversion in a 32-bit build.Lasse Collin2-3/+3
2023-01-12liblzma: Silence another warning from -Wsign-conversion in a 32-bit build.Lasse Collin1-3/+4
It doesn't warn on a 64-bit system because truncating a ptrdiff_t (signed long) to uint32_t is diagnosed under -Wconversion by GCC and -Wshorten-64-to-32 by Clang.
2023-01-12liblzma: Silence a warning from -Wsign-conversion in a 32-bit build.Lasse Collin1-2/+2
2023-01-12Build: Make configure add more warning flags for GCC and Clang.Lasse Collin1-5/+31
-Wstrict-aliasing was removed from the list since it is enabled by -Wall already. A normal build is clean with these on GNU/Linux x86-64 with GCC 12.2.0 and Clang 14.0.6.
2023-01-12Tests: Fix warnings from clang --Wassign-enum.Lasse Collin4-8/+17
Explicitly casting the integer to lzma_check silences the warning. Since such an invalid value is needed in multiple tests, a constant INVALID_LZMA_CHECK_ID was added to tests.h. The use of 0x1000 for lzma_block.check wasn't optimal as if the underlying type is a char then 0x1000 will be truncated to 0. However, in these test cases the value is ignored, thus even with such truncation the test would have passed.
2023-01-12Tests: Silence warnings from -Wsign-conversion.Lasse Collin2-8/+8
Note that assigning an unsigned int to lzma_check doesn't warn on GNU/Linux x86-64 since the enum type is unsigned on that platform. The enum can be signed on some other platform though so it's best to use enumeration type lzma_check in these situations.
2023-01-12liblzma: Silence warnings from clang -Wconditional-uninitialized.Lasse Collin2-4/+6
This is similar to 2ce4f36f179a81d0c6e182a409f363df759d1ad0. The actual initialization of the variables is done inside mythread_sync() macro. Clang doesn't seem to see that the initialization code inside the macro is always executed.
2023-01-12Fix warnings from clang -Wdocumentation.Lasse Collin3-8/+4
2023-01-12Tests: test_lzip_decoder: Remove trailing white-space.Lasse Collin1-2/+2

2023-01-11Add NEWS for 5.4.1.Jia Tan1-0/+70
2023-01-11xz: Fix warning -Wformat-nonliteral on clang in message.c.Jia Tan1-0/+9
clang and gcc differ in how they handle -Wformat-nonliteral. gcc will allow a non-literal format string as long as the function takes its format arguments as a va_list.
2023-01-11Tests: Fix test_filter_flags copy/paste error.Jia Tan1-2/+2
2023-01-11Tests: Fix type-limits warning in test_filter_flags.Jia Tan1-3/+10
This only occurs in test_filter_flags when the BCJ filters are not configured and built. In this case, ARRAY_SIZE() returns 0 and causes a type-limits warning with the loop variable since an unsigned number will always be >= 0.
2023-01-10liblzma: CLMUL CRC64: Work around a bug in MSVC, second attempt.Lasse Collin1-0/+18
This affects only 32-bit x86 builds. x86-64 is OK as is. I still cannot easily test this myself. The reporter has tested this and it passes the tests included in the CMake build and performance is good: raw CRC64 is 2-3 times faster than the C version of the slice-by-four method. (Note that liblzma doesn't include a MSVC-compatible version of the 32-bit x86 assembly code for the slice-by-four method.) Thanks to Iouri Kharon for figuring out a fix, testing, and benchmarking.
2023-01-11Tests: Fix unused function warning in test_block_header.Jia Tan1-0/+4
One of the global arrays of filters was only used in a test that required both encoders and decoders to be configured in the build.
2023-01-11Tests: Fix unused function warning in test_index_hash.Jia Tan1-3/+1
test_index_hash does not use fill_index_hash() unless both encoders and decoders are configured in the build.
2023-01-11CI/CD: Add 32-bit build and test steps to Ubuntu autotools runner.Jia Tan1-1/+6
If all goes well, Mac autotools and Linux and Mac CMake will be added later for 32-bit builds.
2023-01-11CI/CD: Enables warnings as errors in autotool build.Jia Tan1-1/+1
This will help us catch warnings and potential bugs in builds that are not often tested by us.
2023-01-11CI/CD: Add -f argument to set CFLAGS in ci_build.sh.Jia Tan1-2/+6
For now, the suggested option is for -m32 only, but this can be updated later if other flags are deemed useful.
2023-01-10Revert "liblzma: CLMUL CRC64: Workaround a bug in MSVC (VS2015-2022)."Lasse Collin1-6/+0
This reverts commit 36edc65ab4cf10a131f239acbd423b4510ba52d5. It was reported that it wasn't a good enough fix and MSVC still produced (different kind of) bad code when building for 32-bit x86 if optimizations are enabled. Thanks to Iouri Kharon.
2023-01-10sysdefs.h: Don't include strings.h anymore.Lasse Collin1-6/+0
On some platforms src/xz/suffix.c may need <strings.h> for strcasecmp() but suffix.c includes the header when it needs it. Unless there is an old system that otherwise supports enough C99 to build XZ Utils but doesn't have C89/C90-compatible <string.h>, there should be no need to include <strings.h> in sysdefs.h.
2023-01-10xz: Include <strings.h> in suffix.c if needed for strcasecmp().Lasse Collin1-0/+3
SUSv2 and POSIX.1‐2017 declare only a few functions in <strings.h>. Of these, strcasecmp() is used on some platforms in suffix.c. Nothing else in the project needs <strings.h> (at least if building on a modern system). sysdefs.h currently includes <strings.h> if HAVE_STRINGS_H is defined and suffix.c relied on this. Note that dos/config.h doesn't #define HAVE_STRINGS_H even though DJGPP does have strings.h. It isn't needed with DJGPP as strcasecmp() is also in <string.h> in DJGPP.
2023-01-10sysdefs.h: Fix a comment.Lasse Collin1-1/+1
2023-01-10sysdefs.h: Don't include memory.h anymore even if it were available.Lasse Collin1-6/+2
It quite probably was never needed, that is, any system where memory.h was required likely couldn't compile XZ Utils for other reasons anyway. XZ Utils 5.2.6 and later source packages were generated using Autoconf 2.71 which no longer defines HAVE_MEMORY_H. So the code being removed is no longer used anyway.
2023-01-10CMake: Fix appending to CMAKE_RC_FLAGS.Lasse Collin1-1/+1
It's a string, not a list. It only worked when the variable was empty. Thanks to Iouri Kharon.
2023-01-10Windows: Update INSTALL-MSVC.txt to recommend CMake over project files.Lasse Collin1-7/+12
2023-01-09CMake: Fix windres issues again.Lasse Collin1-12/+23
At least on some systems, GNU windres needs --use-temp-file in addition to the \x20 hack to avoid spaces in the command line argument. Hovever, that \x20 syntax is broken with llvm-windres version 15.0.0 (results in "XZx20Utils") but luckily it works with a regular space. Thus it is best to limit the workarounds to GNU toolchain on Windows.
2023-01-09Tests: test_filter_flags: Clean up minor issues.Lasse Collin1-75/+78
Here are the list of the most significant issues addressed: - Avoid using internal common.h header. It's not good to copy the constants like this but common.h cannot be included for use outside of liblzma. This is the quickest thing to do that could be fixed later. - Omit the INIT_FILTER macro. Initialization should be done with just regular designated initializers. - Use start_offset = 257 for BCJ tests. It demonstrates that Filter Flags encoder and decoder don't validate the options thoroughly. 257 is valid only for the x86 filter. This is a bit silly but not a significant problem in practice because the encoder and decoder initialization functions will catch bad alignment still. Perhaps this should be fixed but it's not urgent and doesn't need to be in 5.4.x. - Various tweaks to comments such as filter id -> Filter ID
2023-01-09Tests: Refactors existing filter flags tests.Jia Tan1-198/+457
Converts the existing filter flags tests into tuktests.
2023-01-09liblzma: CLMUL CRC64: Workaround a bug in MSVC (VS2015-2022).Lasse Collin1-0/+6
I haven't tested with MSVC myself and there doesn't seem to be information about the problem online, so I'm relying on the bug report. Thanks to Iouri Kharon for the bug report and the patch.
2023-01-09CMake: Fix a copypaste error in xzdec Windows resource file handling.Lasse Collin1-2/+2
It was my mistake. Thanks to Iouri Kharon for the bug report.
2023-01-08Tests: tuktest.h: Support tuktest_malloc(0).Lasse Collin1-2/+2
It's not needed in XZ Utils at least for now. It's good to support it still because if such use is needed later, it wouldn't be caught on GNU/Linux since malloc(0) from glibc returns non-NULL.

2023-01-08Build: Require that _mm_set_epi64x() is usable to enable CLMUL support.Lasse Collin2-3/+8
VS2013 doesn't have _mm_set_epi64x() so this way CLMUL gets disabled with VS2013. Thanks to Iouri Kharon for the bug report.
2023-01-07CI/CD: Split CMake Linux and MacOS build phase to build and test.Jia Tan1-2/+6
The phase split was only done for Autotools before, so should also apply to CMake.
2023-01-07CI/CD: Reduce job runners to 4 instead of using matrix strategy.Jia Tan1-12/+83
The old version used too many runners that resulted in unnecessary dependency downloads. Now, the runners are reused for the different configurations for each OS and build system.
2023-01-07CI/CD: Add new -p (PHASE) argument to ci_build.shJia Tan1-64/+76
The new PHASE argument can be build, test, or all. all is the default. This way, the CI/CD script can differentiate between the build and test phases to make it easier to track down errors when they happen.

2023-01-05liblzma: Remove common.h include from common/index.h.Jia Tan4-2/+10
common/index.h is needed by liblzma internally and tests. common.h will include and define many things that are not needed by the tests. Also, this prevents include order problems because common.h will redefine LZMA_API resulting in a warning.

HAVE_DECL_PROGRAM_INVOCATION_NAME is renamed to HAVE_PROGRAM_INVOCATION_NAME. Previously, HAVE_DECL_PROGRAM_INVOCATION_NAME was always set when building with autotools. CMake would only set this when it was 1, and the dos/config.h did not define it. The new macro definition is consistent across build systems.

2022-12-30liblzma: Includes sys/time.h conditionally in mythreadJia Tan1-1/+7
Previously, <sys/time.h> was always included, even if mythread only used clock_gettime. <time.h> is still needed even if clock_gettime is not used though because struct timespec is needed for mythread_condtime.
2022-12-30Build: No longer require HAVE_DECL_CLOCK_MONOTONIC to always be set.Jia Tan4-11/+11
Previously, if threading was enabled HAVE_DECL_CLOCK_MONOTONIC would always be set to 0 or 1. However, this macro was needed in xz so if xz was not built with threading and HAVE_DECL_CLOCK_MONOTONIC was not defined but HAVE_CLOCK_GETTIME was, it caused a warning during build. Now, HAVE_DECL_CLOCK_MONOTONIC has been renamed to HAVE_CLOCK_MONOTONIC and will only be set if it is 1.

If someone sets up Clang to define __GNUC__ to 10 or greater then symvers broke. __has_attribute is supported by such GCC and Clang versions that don't support __symver__ so this should be much better and simpler way to detect if __symver__ is actually supported.

2022-12-01liblzma: Omit zero-skipping from ARM64 filter.Lasse Collin2-59/+24
It has some complicated downsides and its usefulness is more limited than I originally thought. So this change is bad for certain very specific situations but a generic solution that works for other filters (and is otherwise better too) is planned anyway. And this way 7-Zip can use the same compatible filter for the .7z format. This is still marked as experimental with a new temporary Filter ID.

2022-11-28xz: Use lzma_str_from_filters().Lasse Collin2-175/+28
Two uses: Displaying encoder filter chain when compressing with -vv, and displaying the decoder filter chain in --list -vv.
2022-11-28liblzma: Add lzma_str_to_filters, _from_filters, and _list_filters.Lasse Collin5-0/+1567
lzma_str_to_filters() uses static error messages which makes them not very precise. It tells the position in the string where an error occurred though which helps quite a bit if applications take advantage of it. Dynamic error messages can be added later with a new flag if it seems important enough.

2022-11-28liblzma: Use LZMA1EXT feature in lzma_alone_decoder().Lasse Collin1-5/+13
This avoids the need to use the slightly ugly method to set the uncompressed size.
2022-11-27liblzma: Add LZMA_FILTER_LZMA1EXT to support LZMA1 without end marker.Lasse Collin9-15/+204
Some file formats need support for LZMA1 streams that don't use the end of payload marker (EOPM) alias end of stream (EOS) marker. So far liblzma API has supported decompressing such streams via lzma_alone_decoder() when .lzma header specifies a known uncompressed size. Encoding support hasn't been available in the API. Instead of adding a new LZMA1-only API for this purpose, this commit adds a new filter ID for use with raw encoder and decoder. The main benefit of this approach is that then also filter chains are possible, for example, if someone wants to implement support for .7z files that use the x86 BCJ filter with LZMA1 (not BCJ2 as that isn't supported in liblzma).

2022-11-24liblzma: Allow nice_len 2 and 3 even if match finder requires 3 or 4.Lasse Collin3-8/+26
That is, if the specified nice_len is smaller than the minimum of the match finder, silently use the match finder's minimum value instead of reporting an error. The old behavior is annoying to users and it complicates xz options handling too.
2022-11-24liblzma: Add lzma_filters_update() support to the multi-threaded encoder.Lasse Collin2-23/+109
A tiny downside of this is that now a 1-4 tiny allocations are made for every Block because each worker thread needs its own copy of the filter chain.
2022-11-24Update THANKS.Lasse Collin1-0/+1
2022-11-24Build: Don't put GNU/Linux-specific symbol versions into static liblzma.Lasse Collin3-49/+111
It not only makes no sense to put symbol versions into a static library but it can also cause breakage. By default Libtool #defines PIC if building a shared library and doesn't define it for static libraries. This is documented in the Libtool manual. It can be overriden using --with-pic or --without-pic. configure.ac detects if --with-pic or --without-pic is used and then gives an error if neither --disable-shared nor --disable-static was used at the same time. Thus, in normal situations it works to build both shared and static library at the same time on GNU/Linux, only --with-pic or --without-pic requires that only one type of library is built. Thanks to John Paul Adrian Glaubitz from Debian for reporting the problem that occurred on ia64: https://www.mail-archive.com/xz-devel@tukaani.org/msg00610.html
2022-11-24liblzma: Refactor to use lzma_filters_free().Lasse Collin2-21/+6
lzma_filters_free() sets the options to NULL and ids to LZMA_VLI_UNKNOWN so there is no need to do it by caller; the filter arrays will always be left in a safe state. Also use memcpy() instead of a loop to copy a filter chain when it is known to be safe to copy LZMA_FILTERS_MAX + 1 (even if the elements past the terminator might be uninitialized).
2022-11-24liblzma: Fix another invalid free() after memory allocation failure.Lasse Collin1-0/+4
This time it can happen when lzma_stream_encoder_mt() is used to reinitialize an existing multi-threaded Stream encoder and one of 1-4 tiny allocations in lzma_filters_copy() fail. It's very similar to the previous bug 10430fbf3820dafd4eafd38ec8be161a6978ed2b, happening with an array of lzma_filter structures whose old options are freed but the replacement never arrives due to a memory allocation failure in lzma_filters_copy().
2022-11-24liblzma: Add support for LZMA_SYNC_FLUSH in the Block encoder.Jia Tan1-0/+1
The documentation mentions that lzma_block_encoder() supports LZMA_SYNC_FLUSH but it was never added to supported_actions[] in the internal structure. Because of this, LZMA_SYNC_FLUSH could not be used with the Block encoder unless it was the next coder after something like stream_encoder() or stream_encoder_mt().
2022-11-24liblzma: Add new API function lzma_filters_free().Lasse Collin4-0/+49

2022-11-23liblzma: Fix invalid free() after memory allocation failure.Lasse Collin1-8/+31
The bug was in the single-threaded .xz Stream encoder in the code that is used for both re-initialization and for lzma_filters_update(). To trigger it, an application had to either re-initialize an existing encoder instance with lzma_stream_encoder() or use lzma_filters_update(), and then one of the 1-4 tiny allocations in lzma_filters_copy() (called from stream_encoder_update()) must fail. An error was correctly reported but the encoder state was corrupted. This is related to the recent fix in f8ee61e74eb40600445fdb601c374d582e1e9c8a which is good but it wasn't enough to fix the main problem in stream_encoder.c.

2022-11-22liblzma: Fix infinite loop in LZMA encoder init with dict_size >= 2 GiB.Lasse Collin1-4/+15
The encoder doesn't support dictionary sizes larger than 1536 MiB. This is validated, for example, when calculating the memory usage via lzma_raw_encoder_memusage(). It is also enforced by the LZ part of the encoder initialization. However, LZMA encoder with LZMA_MODE_NORMAL did an unsafe calculation with dict_size before such validation and that results in an infinite loop if dict_size was 2 << 30 or greater.

2022-11-14Revert "liblzma: Simple/BCJ filters: Allow disabling generic BCJ options."Lasse Collin9-11/+10
This reverts commit 177bdc922cb17bd0fd831ab8139dfae912a5c2b8 and also does equivalent change to arm64.c. Now that ARM64 filter will use lzma_options_bcj, this change is not needed anymore.
2022-11-14Replace the experimental ARM64 filter with a new experimental version.Lasse Collin11-287/+147
This is incompatible with the previous version. This has space/tab fixes in filter_*.c and bcj.h too.
2022-11-14liblzma: Add fast CRC64 for 32/64-bit x86 using SSSE3 + SSE4.1 + CLMUL.Lasse Collin5-13/+554
It also works on E2K as it supports these intrinsics. On x86-64 runtime detection is used so the code keeps working on older processors too. A CLMUL-only build can be done by using -msse4.1 -mpclmul in CFLAGS and this will reduce the library size since the generic implementation and its 8 KiB lookup table will be omitted. On 32-bit x86 this isn't used by default for now because by default on 32-bit x86 the separate assembly file crc64_x86.S is used. If --disable-assembler is used then this new CLMUL code is used the same way as on 64-bit x86. However, a CLMUL-only build (-msse4.1 -mpclmul) won't omit the 8 KiB lookup table on 32-bit x86 due to a currently-missing check for disabled assembler usage. The configure.ac check should be such that the code won't be built if something in the toolchain doesn't support it but --disable-clmul-crc option can be used to unconditionally disable this feature. CLMUL speeds up decompression of files that have compressed very well (assuming CRC64 is used as a check type). It is know that the CLMUL code is significantly slower than the generic code for tiny inputs (especially 1-8 bytes but up to 16 bytes). If that is a real-world problem then there is already a commented-out variant that uses the generic version for small inputs. Thanks to Ilya Kurdyukov for the original patch which was derived from a white paper from Intel [1] (published in 2009) and public domain code from [2] (released in 2016).
