Lasse Collin 22af94128b Add SPDX license identifier into 0BSD source code files. 2024-02-14 18:31:16 +02:00
Lasse Collin 689e0228ba Change most public domain parts to 0BSD. 
Translations and doc/xz-file-format.txt and doc/lzma-file-format.txt
were not touched.

COPYING.0BSD was added.

Jia Tan 116e81f002 Build: Removes redundant check for LZMA1 filter support. 2023-03-23 21:48:52 +08:00
Lasse Collin f4c95ba94b liblzma: Rename lzma_presets.c back to lzma_encoder_presets.c. 
It would be too annoying to update other build systems
just because of this.

Lasse Collin 4cc584985c Build: Build LZMA1/2 presets also when only decoder is wanted. 
People shouldn't rely on the presets when decoding raw streams,
but xz uses the presets as the starting point for raw decoder
options anyway.

lzma_encocder_presets.c was renamed to lzma_presets.c to
make it clear it's not used solely by the encoder code.

Lasse Collin f42ee98166 Build system fixes 
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.
