2009-06-30	Build system fixes	Lasse Collin	1	-1/+10
	Don't use libtool convenience libraries to avoid recently discovered long-standing subtle but somewhat severe bugs in libtool (at least 1.5.22 and 2.2.6 are affected). It was found when porting XZ Utils to Windows <http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html> but the problem is significant also e.g. on GNU/Linux. Unless --disable-shared is passed to configure, static library built from a set of convenience libraries will contain PIC objects. That is, while libtool builds non-PIC objects too, only PIC objects will be used from the convenience libraries. On 32-bit x86 (tested on mobile XP2400+), using PIC instead of non-PIC makes the decompressor 10 % slower with the default CFLAGS. So while xz was linked against static liblzma by default, it got the slower PIC objects unless --disable-shared was used. I tend develop and benchmark with --disable-shared due to faster build time, so I hadn't noticed the problem in benchmarks earlier. This commit also adds support for building Windows resources into liblzma and executables.
2009-06-27	Added missing $(EXEEXT).	Lasse Collin	1	-1/+1

2009-06-27	Create correct symlinks even when	Lasse Collin	1	-8/+13
	--program-{prefix,suffix,transform} is passed to configure.
2009-06-26	Rename process.[hc] to coder.[hc] and io.[hc] to file_io.[hc]	Lasse Collin	1	-4/+4
	to avoid problems on systems with system headers with those names.
2009-06-26	Fix @variables@ to $(variables) in Makefile.am files.	Lasse Collin	1	-10/+11
	Fix the ordering of libgnu.a and LTLIBINTL on the linker command line and added missing LTLIBINTL to tests/Makefile.am.
2009-04-13	Put the interesting parts of XZ Utils into the public domain.	Lasse Collin	1	-10/+3
	Some minor documentation cleanups were made at the same time.
2009-02-07	Make it easy to choose if command line tools should be	Lasse Collin	1	-5/+3
	linked statically or dynamically against liblzma. The default is still to use static liblzma, but it can now be changed by passing --enable-dynamic to configure. Thanks to Mike Frysinger for the original patch. Fixed a few minor bugs in configure.ac.
2009-02-05	Various code cleanups the the xz command line tool.	Lasse Collin	1	-0/+2
	It now builds with MinGW.
2008-12-31	Remove lzma_init() and other init functions from liblzma API.	Lasse Collin	1	-4/+1
	Half of developers were already forgetting to use these functions, which could have caused total breakage in some future liblzma version or even now if --enable-small was used. Now liblzma uses pthread_once() to do the initializations unless it has been built with --disable-threads which make these initializations thread-unsafe. When --enable-small isn't used, liblzma currently gets needlessly linked against libpthread (on systems that have it). While it is stupid for now, liblzma will need threads in future anyway, so this stupidity will be temporary only. When --enable-small is used, different code CRC32 and CRC64 is now used than without --enable-small. This made the resulting binary slightly smaller, but the main reason was to clean it up and to handle the lack of lzma_init_check(). The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not sure if it works correctly and portably for static linking (Libs.private includes -pthread or other operating system specific flags). Hopefully someone complains if it is bad. lzma_rc_prices[] is now included as a precomputed array even with --enable-small. It's just 128 bytes now that it uses uint8_t instead of uint32_t. Smaller array seemed to be at least as fast as the more bloated uint32_t array on x86; hopefully it's not bad on other architectures.
2008-11-19	Renamed lzma to xz and lzmadec to xzdec. We create symlinks	Lasse Collin	1	-0/+74
	lzma, unlzma, and lzcat in "make install" for backwards compatibility with LZMA Utils 4.32.x; I'm not sure if this should be the default though.
