2023-10-18	liblzma: CRC_USE_GENERIC_FOR_SMALL_INPUTS cannot be used with ifunc.	Lasse Collin	1	-1/+3

2023-10-18	liblzma: Include common.h in crc_common.h.	Lasse Collin	1	-0/+3
	crc_common.h depends on common.h. The headers include common.h except when there is a reason to not do so.
2023-10-18	liblzma: Add include guards to crc_common.h.	Jia Tan	1	-0/+5

2023-10-18	liblzma: Create crc_always_inline macro.	Jia Tan	1	-0/+15
	This macro must be used instead of the inline keyword. On MSVC, it is a replacement for __forceinline which is an MSVC specific keyword that should not be used with inline (it will issue a warning if it is). It does not use a build system check to determine if __attribute__((__always_inline__)) since all compilers that can use CLMUL extensions (except the special case for MSVC) should support this attribute. If this assumption is incorrect then it will result in a bug report instead of silently producing slow code.
2023-10-18	liblzma: Create crc_clmul.c.	Jia Tan	1	-180/+10
	Both crc32_clmul() and crc64_clmul() are now exported from crc32_clmul.c as lzma_crc32_clmul() and lzma_crc64_clmul(). This ensures that is_clmul_supported() (now lzma_is_clmul_supported()) is not duplicated between crc32_fast.c and crc64_fast.c. Also, it encapsulates the complexity of the CLMUL implementations into a single file and reduces the complexity of crc32_fast.c and crc64_fast.c. Before, CLMUL code was present in crc32_fast.c, crc64_fast.c, and crc_common.h. During the conversion, various cleanups were applied to code (thanks to Lasse Collin) including: - Require using semicolons with MASK_/L/H/LH macros. - Variable typing and const handling improvements. - Improvements to comments. - Fixes to the pragmas used. - Removed unneeded variables. - Whitespace improvements. - Fixed CRC_USE_GENERIC_FOR_SMALL_INPUTS handling. - Silenced warnings and removed the need for some #pragmas
2023-10-18	liblzma: Define CRC_USE_IFUNC in crc_common.h.	Jia Tan	1	-0/+5
	When ifunc is supported, we can define a simpler macro instead of repeating the more complex check in both crc32_fast.c and crc64_fast.c.
2023-10-13	liblzma: Moved CLMUL CRC logic to crc_common.h.	Hans Jansen	1	-2/+228
	crc64_fast.c was updated to use the code from crc_common.h instead.
2023-10-13	liblzma: Rename crc_macros.h to crc_common.h.	Hans Jansen	1	-1/+1

2009-10-04	Use a tuklib module for integer handling.	Lasse Collin	1	-2/+0
	This replaces bswap.h and integer.h. The tuklib module uses <byteswap.h> on GNU, <sys/endian.h> on *BSDs and <sys/byteorder.h> on Solaris, which may contain optimized code like inline assembly.
2009-04-13	Put the interesting parts of XZ Utils into the public domain.	Lasse Collin	1	-5/+4
	Some minor documentation cleanups were made at the same time.
2008-06-18	Update the code to mostly match the new simpler file format	Lasse Collin	1	-1/+1
	specification. Simplify things by removing most of the support for known uncompressed size in most places. There are some miscellaneous changes here and there too. The API of liblzma has got many changes and still some more will be done soon. While most of the code has been updated, some things are not fixed (the command line tool will choke with invalid filter chain, if nothing else). Subblock filter is somewhat broken for now. It will be updated once the encoded format of the Subblock filter has been decided.
