2011-04-11	liblzma: Add lzma_stream_encoder_mt() for threaded compression.	Lasse Collin	1	-0/+7
	This is the simplest method to do threading, which splits the uncompressed data into blocks and compresses them independently from each other. There's room for improvement especially to reduce the memory usage, but nevertheless, this is a good start.
2011-04-11	liblzma: Make lzma_stream_encoder_init() static (second try).	Lasse Collin	1	-1/+0
	It's an internal function and it's not needed by anything outside stream_encoder.c.
2011-04-11	Revert "liblzma: Make lzma_stream_encoder_init() static."	Lasse Collin	1	-0/+1
	This reverts commit 352ac82db5d3f64585c07b39e4759388dec0e4d7. I don't know what I was thinking.

2009-11-22	Make fastpos.h use tuklib_integer.h instead of bsr.h	Lasse Collin	1	-1/+0
	when --enable-small has been specified.
2009-11-15	Add lzma_physmem().	Lasse Collin	1	-0/+1
	I had hoped to keep liblzma as purely a compression library as possible (e.g. file I/O will go into a different library), but it seems that applications linking agaisnt liblzma need some way to determine the memory usage limit, and knowing the amount of RAM is one reasonable way to help making such decisions. Thanks to Jonathan Nieder for the original patch.
2009-06-30	Build system fixes	Lasse Collin	1	-0/+67
	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.
