Andre Noll 706b049675 l10n: de.po: Fix typo: Schießen -> Schließen.
That's a funny one since "schießen" means to shoot :)

Lasse Collin efa7b0a210 xzgrep: Avoid passing both -q and -l to grep.
The behavior of grep -ql varies:
  - GNU grep behaves like grep -q.
  - OpenBSD grep behaves like grep -l.

POSIX doesn't make it 100 % clear what behavior is expected.
Anyway, using both -q and -l at the same time makes no sense
so both options simply should never be used at the same time.

Thanks to Christian Weisgerber.

Lasse Collin c4911f2db3 Build: Detect supported compiler warning flags better.
Clang and nowadays also GCC accept any -Wfoobar option
but then may give a warning that an unknown warning option
was specified. To avoid adding unsupported warning options,
the options are now tested with -Werror.

Thanks to Charles Diza.

Lasse Collin 76e75522ed Update NEWS for 5.0.7. 2014-09-20 21:01:21 +03:00
Lasse Collin d62028b4c1 liblzma: Fix a portability problem in Makefile.am.
POSIX supports $< only in inference rules (suffix rules).
Using it elsewhere is a GNU make extension and doesn't
work e.g. with OpenBSD make.

Thanks to Christian Weisgerber for the patch.

Lasse Collin 0e0f34b8e4 liblzma: Add support for lzma_block.ignore_check.
Note that this slightly changes how lzma_block_header_decode()
has been documented. Earlier it said that the .version is set
to the lowest required value, but now it says that the .version
field is kept unchanged if possible. In practice this doesn't
affect any old code, because before this commit the only
possible .version was 0.

Lasse Collin 5dcffdbcc2 liblzma: SHA-256: Optimize the Maj macro slightly.
The Maj macro is used where multiple things are added
together, so making Maj a sum of two expressions allows
some extra freedom for the compiler to schedule the
instructions.

I learned this trick from
<http://www.hackersdelight.org/corres.txt>.

Lasse Collin a9477d1e0c liblzma: SHA-256: Optimize the way rotations are done.
This looks weird because the rotations become sequential,
but it helps quite a bit on both 32-bit and 64-bit x86:

  - It requires fewer instructions on two-operand
    instruction sets like x86.

  - It requires one register less which matters especially
    on 32-bit x86.

I hope this doesn't hurt other archs.

I didn't invent this idea myself, but I don't remember where
I saw it first.

Lasse Collin 5a76c7c8ee liblzma: SHA-256: Remove the GCC #pragma that became unneeded.
The unrolling in the previous commit should avoid the
situation where a compiler may think that an uninitialized
variable might be accessed.
2014-08-03 20:38:13 +03:00
Lasse Collin 9a096f8e57 liblzma: SHA-256: Unroll a little more.
This way a branch isn't needed for each operation
to choose between blk0 and blk2, and still the code
doesn't grow as much as it would with full unrolling.

Lasse Collin 544aaa3d13 liblzma: Use lzma_memcmplen() in normal mode of LZMA.
Two locations were not changed yet because the simplest change
assumes that the initial "len" may be greater than "limit".

Lasse Collin e1c8f1d01f liblzma: Add lzma_memcmplen() for fast memory comparison.
This commit just adds the function. Its uses will be in
separate commits.

This hasn't been tested much yet and it's perhaps a bit early
to commit it but if there are bugs they should get found quite
quickly.

Thanks to Jun I Jin from Intel for help and for pointing out
that string comparison needs to be optimized in liblzma.

Lasse Collin ceca379017 xzgrep: exit 0 when at least one file matches.
Mimic the original grep behavior and return exit_success when

Lasse Collin da1718f266 liblzma: Use lzma_alloc_zero() in LZ encoder initialization.
This avoids a memzero() call for a newly-allocated memory,
which can be expensive when encoding small streams with
an over-sized dictionary.

To avoid using lzma_alloc_zero() for memory that doesn't
need to be zeroed, lzma_mf.son is now allocated separately,
which requires handling it separately in normalize() too.

Thanks to Vincenzo Innocente for reporting the problem.

Lasse Collin 4d5b7b3fda liblzma: Rename the private API header lzma/lzma.h to lzma/lzma12.h.
It can be confusing that two header files have the same name.
The public API file is still lzma.h.

Lasse Collin 1555a9c566 Build: Fix the combination of --disable-xzdec --enable-lzmadec.
In this case "make install" could fail if the man page directory
didn't already exist at the destination. If it did exist, a
dangling symlink was created there. Now the link is omitted
instead. This isn't the best fix but it's better than the old
behavior.

Lasse Collin 56056571df Build: Add --disable-doc to configure. 2014-04-25 17:44:26 +03:00
Lasse Collin 6de61d8721 Update INSTALL.
Add a note about failing "make check". The source of
the problem should be fixed in libtool (if it really is
a libtool bug and not mine) but I'm unable to spend time
on that for now. Thanks to Nelson H. F. Beebe for reporting
the issue.

Add a note about a possible need to run "ldconfig" after
"make install".

Lasse Collin 54df428799 xz: Rename a variable to avoid a namespace collision on Solaris.
I don't know the details but I have an impression that there's
no problem in practice if using GCC since people have built xz
with GCC (without patching xz), but renaming the variable cannot
hurt either.

Thanks to Mark Ashley.

Lasse Collin 5876ca27da Docs: Add example program for threaded encoding.
I didn't add -DLZMA_UNSTABLE to Makefile so one has to
specify it manually as long as LZMA_UNSTABLE is needed.
