2009-06-30Build system fixesLasse Collin1-51/+0
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.
2009-06-26Fix @variables@ to $(variables) in Makefile.am files.Lasse Collin1-4/+4
Fix the ordering of libgnu.a and LTLIBINTL on the linker command line and added missing LTLIBINTL to tests/Makefile.am.
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-10/+3
Some minor documentation cleanups were made at the same time.
2008-09-27Some API changes, bug fixes, cleanups etc.Lasse Collin1-2/+2
2008-09-17Miscellaneous LZ and LZMA encoder cleanupsLasse Collin1-1/+0
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-14/+23
broken. API has changed a lot and it will still change a little more here and there. The command line tool doesn't have all the required changes to reflect the API changes, so it's easy to get "internal error" or trigger assertions.
2008-04-24Fix fastpos problem in Makefile.am when built with --enable-small.Lasse Collin1-1/+4
2008-01-15Revised the fastpos code. It now uses the slightly fasterLasse Collin1-0/+4
table-based version from LZMA SDK 4.57. This should be fast on most systems. A simpler and smaller alternative version is also provided. On some CPUs this can be even a little faster than the default table-based version (see comments in fastpos.h), but on most systems the table-based code is faster.
