2009-10-02	Make liblzma produce the same output on both endiannesses.	Lasse Collin	1	-0/+1
	Seems that it is a problem in some cases if the same version of XZ Utils produces different output on different endiannesses, so this commit fixes that problem. The output will still vary between different XZ Utils versions, but I cannot avoid that for now. This commit bloatens the code on big endian systems by 1 KiB, which should be OK since liblzma is bloated already. ;-)
2009-06-30	Build system fixes	Lasse Collin	1	-0/+21
	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.
