Lasse Collin 23fb9e3a32 CMake: Rename CHECK_ATTR_IFUNC to ALLOW_ATTR_IFUNC.
It's so that there's a clear difference in wording compared
to liblzma's integrity check types.

Lasse Collin ee44863ae8 liblzma: Add ifunc implementation to crc64_fast.c.
The ifunc method avoids indirection via the function pointer
crc64_func. This works on GNU/Linux and probably on FreeBSD too.
The previous __attribute((__constructor__)) method is kept for
compatibility with ELF platforms which do support ifunc.

The ifunc method has some limitations, for example, building
liblzma with -fsanitize=address will result in segfaults.
The configure option --disable-ifunc must be used for such builds.

Thanks to Hans Jansen for the original patch.
Closes: https://github.com/tukaani-project/xz/pull/53

Hans Jansen b72d212024 Add ifunc check to CMakeLists.txt
CMake build system will now verify if __attribute__((__ifunc__())) can be
used in the build system. If so, HAVE_FUNC_ATTRIBUTE_IFUNC will be
defined to 1.

Hans Jansen 23b5c36fb7 Add ifunc check to configure.ac
configure.ac will now verify if __attribute__((__ifunc__())) can be used in
the build system. If so, HAVE_FUNC_ATTRIBUTE_IFUNC will be defined to 1.

Jia Tan dbb3a536ed CI: Add apt update command before installing dependencies.
Without the extra command, all of the CI tests were automatically
failing because the Ubuntu servers could not be reached properly.

CMake: Protects against double find_package
Boost iostream uses `find_package` in quiet mode and then again uses
`find_package` with required. This second call triggers a 
`add_library cannot create imported target "ZLIB::ZLIB" because another
target with the same name already exists.`

This can simply be fixed by skipping the alias part on secondary
`find_package` runs.

Jia Tan f36ca7982f liblzma: Slightly rewords lzma_str_list_filters() documentation.
Reword "options required" to "supported options". The previous may have
suggested that the options listed were all required anytime a filter is
used for encoding or decoding. The reword makes this more clear that
adjusting the options is optional.

Jia Tan 3374a5359e liblzma: Adds lzma_nothrow to MicroLZMA API functions.
None of the liblzma functions may throw an exception, so this
attribute should be applied to all liblzma API functions.
2023-05-12 00:00:47 +08:00
Jia Tan 8f23657498 liblzma: Exports lzma_mt_block_size() as an API function.
The lzma_mt_block_size() was previously just an internal function for
the multithreaded .xz encoder. It is used to provide a recommended Block
size for a given filter chain.

This function is helpful to determine the maximum Block size for the
multithreaded .xz encoder when one wants to change the filters between
blocks. Then, this determined Block size can be provided to
lzma_stream_encoder_mt() in the lzma_mt options parameter when
intializing the coder. This requires one to know all the filter chains
they are using before starting to encode (or at least the filter chain
that will need the largest Block size), but that isn't a bad limitation.

Jia Tan d0f33d672a liblzma: Creates IS_ENC_DICT_SIZE_VALID() macro.
This creates an internal liblzma macro to test if the dictionary size
is valid for encoding.

Jia Tan 9ad64bdf30 tuklib_integer.h: Reverts previous commit.
Previous commit 6be460dde0 would cause an
error if the integer size was 32 bit.

Lasse Collin 44c0c5eae9 tuklib_integer.h: Fix a recent copypaste error in Clang detection.
Wrong line was changed in 7062348bf3.
Also, this has >= instead of == since ints larger than 32 bits would
work too even if not relevant in practice.

Jia Tan f41df2ac2f Windows: Include <intrin.h> when needed.
Legacy Windows did not need to #include <intrin.h> to use the MSVC
intrinsics. Newer versions likely just issue a warning, but the MSVC
documentation says to include the header file for the intrinsics we use.

GCC and Clang can "pretend" to be MSVC on Windows, so extra checks are
needed in tuklib_integer.h to only include <intrin.h> when it will is
actually needed.

Jia Tan 7062348bf3 tuklib_integer: Use __builtin_clz() with Clang.
Clang has support for __builtin_clz(), but previously Clang would
fallback to either the MSVC intrinsic or the regular C code. This was
discovered due to a bug where a new version of Clang required the
<intrin.h> header file in order to use the MSVC intrinsics.

Thanks to Anton Kochkov for notifying us about the bug.

Jia Tan 8be5cc3b13 CI: Removes CMakeCache.txt between builds.
If the cache file is not removed, CMake will not reset configurations
back to their default values. In order to make the tests independent, it
is simplest to purge the cache. Unfortunatly, this will slow down the
tests a little and repeat some checks.
