Lasse Collin cf751edfde Added AC_CONFIG_MACRO_DIR to configure.ac. 2009-03-01 09:00:06 +02:00
Lasse Collin 3084d662d2 Cleanups to the code that detects the amount of RAM and
the number of CPU cores. Added support for using sysinfo()
on Linux systems whose libc lacks appropriate sysconf()
support (at least dietlibc). The Autoconf macros were
split into separate files, and CPU core count detection
was moved from hardware.c to cpucores.h. The core count
isn't used for anything real for now, so a problematic
part in process.c was commented out.

Lasse Collin fdbc0cfa71 Changed how the version number is specified in various places.
Now configure.ac will get the version number directly from
src/liblzma/api/lzma/version.h. The intent is to reduce the
number of places where the version number is duplicated. In
future, support for displaying Git commit ID may be added too.

Lasse Collin a3bbbe05d3 Let the user specify custom CFLAGS on the make command
line. Previously custom CFLAGS worked only when they were
passed to configure.

Lasse Collin 880c330938 Make it easy to choose if command line tools should be
linked statically or dynamically against liblzma. The
default is still to use static liblzma, but it can now
be changed by passing --enable-dynamic to configure.
Thanks to Mike Frysinger for the original patch.

Fixed a few minor bugs in configure.ac.

Lasse Collin 99c1c2abfa Updated the x86 assembler code:
- Use call/ret pair to get instruction pointer for PIC.
  - Use PIC only if PIC or __PIC__ is #defined.
  - The code should work on MinGW and Darwin in addition
    to GNU/Linux and Solaris.

Lasse Collin 4fd43cb3a9 Bumped version to 4.999.8beta right after the release
of 4.999.7beta.

Lasse Collin 9c45658ddc Disable both Subblock encoder and decoder my default,
since they are not finished and may have security issues too.

Lasse Collin d1d17a40d3 Prepare for 4.999.7beta release. 2008-12-31 17:41:46 +02:00
Lasse Collin 7eea8bec3a Fixed missing quoting in configure.ac. 2008-12-31 00:57:27 +02:00
Lasse Collin 7ed9d943b3 Remove lzma_init() and other init functions from liblzma API.
Half of developers were already forgetting to use these
functions, which could have caused total breakage in some future
liblzma version or even now if --enable-small was used. Now
liblzma uses pthread_once() to do the initializations unless
it has been built with --disable-threads which make these
initializations thread-unsafe.

When --enable-small isn't used, liblzma currently gets needlessly
linked against libpthread (on systems that have it). While it is
stupid for now, liblzma will need threads in future anyway, so
this stupidity will be temporary only.

When --enable-small is used, different code CRC32 and CRC64 is
now used than without --enable-small. This made the resulting
binary slightly smaller, but the main reason was to clean it up
and to handle the lack of lzma_init_check().

The pkg-config file lzma.pc was renamed to liblzma.pc. I'm not
sure if it works correctly and portably for static linking
(Libs.private includes -pthread or other operating system
specific flags). Hopefully someone complains if it is bad.

lzma_rc_prices[] is now included as a precomputed array even
with --enable-small. It's just 128 bytes now that it uses uint8_t
instead of uint32_t. Smaller array seemed to be at least as fast
as the more bloated uint32_t array on x86; hopefully it's not bad
on other architectures.

Lasse Collin 1ceebcf7e1 Name the package "xz" in configure.ac. 2008-12-13 00:54:11 +02:00
Lasse Collin a94bf00d0a Some adjustments to GCC warning flags. The important change
is the removal of -pedantic. It messes up -Werror (which I
really want to keep so that I don't miss any warnings) with
printf format strings that are in POSIX but not in C99.
2008-12-12 22:43:21 +02:00
Lasse Collin 54f716ba89 Added missing check for uint16_t. 2008-11-19 23:55:22 +02:00
Lasse Collin 1880a3927b Renamed lzma to xz and lzmadec to xzdec. We create symlinks
lzma, unlzma, and lzcat in "make install" for backwards
compatibility with LZMA Utils 4.32.x; I'm not sure if this
should be the default though.

Lasse Collin e114502b2b Oh well, big messy commit again. Some highlights:
- Updated to the latest, probably final file format version.
  - Command line tool reworked to not use threads anymore.
    Threading will probably go into liblzma anyway.
  - Memory usage limit is now about 30 % for uncompression
    and about 90 % for compression.
  - Progress indicator with --verbose
  - Simplified --help and full --long-help
  - Upgraded to the last LGPLv2.1+ getopt_long from gnulib.
  - Some bug fixes

Lasse Collin 1dcecfb09b Some API changes, bug fixes, cleanups etc. 2008-09-27 19:09:21 +03:00
Lasse Collin 9373e81e18 Bumped version to 4.999.6alpha. 2008-09-10 19:16:32 +03:00
Lasse Collin 3b34851de1 Sort of garbage collection commit. :-| Many things are still
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.
2008-08-28 22:53:15 +03:00
Lasse Collin 7d17818cec Update the code to mostly match the new simpler file format
specification. Simplify things by removing most of the
support for known uncompressed size in most places.
There are some miscellaneous changes here and there too.

The API of liblzma has got many changes and still some
more will be done soon. While most of the code has been
updated, some things are not fixed (the command line tool
will choke with invalid filter chain, if nothing else).

Subblock filter is somewhat broken for now. It will be
updated once the encoded format of the Subblock filter
has been decided.

Lasse Collin ed6664146f Remove support for pre-C89 libc versions that lack memcpy,
memmove, and memset.
2008-05-11 14:24:42 +03:00
Lasse Collin b09464bf9a Improved C99 compiler detection in configure.ac. It will
pass -std=gnu99 instead of -std=c99 to GCC now, but -pedantic
should still give warnings about GNU extensions like before
except with some special keywords like asm().
2008-05-11 14:17:21 +03:00
Lasse Collin 8f804c29aa Bumped version number to 4.999.3alpha. It will become 5.0.0
once we have a stable release (won't be very soon). The
version number is no longer related to version of LZMA SDK.

Made some small Automake-related changes to toplevel
Makefile.am and configure.ac.
2008-04-25 13:32:35 +03:00
Lasse Collin 641998c3e1 Replaced the range decoder optimization that used arithmetic
right shift with as fast version that doesn't need
arithmetic right shift. Removed the related check from
configure.ac.
2008-03-24 16:38:40 +02:00
Lasse Collin 03e0e8a0d7 Added autoconf check to detect if we can use arithmetic
right shift for optimizations.
2008-03-22 14:18:29 +02:00
Lasse Collin 61dc82f3e3 Added the debug directory and the first debug tool
(sync_flush). These tools are not built unless the
user runs "make" in the debug directory.
2008-01-18 20:18:08 +02:00
Lasse Collin 079c4f7fc2 Don't add -g to CFLAGS when --enable-debug is specified.
It's the job of the user to put that in CFLAGS.
2008-01-18 17:21:24 +02:00
Lasse Collin f3c88e8b8d Fixed assembler detection in configure.ac, and added
detection for x86_64.
2008-01-15 13:29:14 +02:00
Lasse Collin 382808514a Define HAVE_ASM_X86 when x86 assembler optimizations are
used. This #define will be useful for inline assembly.
2008-01-09 20:05:57 +02:00
Lasse Collin c7189d981a Test for $GCC = yes instead of if it is non-empty. This
way it is possible to use ac_cv_c_compiler_gnu=no to
force configure to think it is using non-GNU C compiler.
2008-01-07 23:14:25 +02:00
Lasse Collin 1239649f96 Cosmetic changes to configure.ac. 2008-01-06 21:47:17 +02:00
Lasse Collin 88ee301ec2 Automatically disable assembler code on Darwin x86.
Darwin has different ABI than GNU+Linux and Solaris,
thus the assembler code doesn't assemble on Darwin.
2008-01-06 19:46:38 +02:00
Lasse Collin 4e7e54c4c5 Introduced compatibility with systems that have pre-C99
or no inttypes.h. This is useful when the compiler has
good enough support for C99, but libc headers don't.

Changed liblzma API so that sys/types.h and inttypes.h
have to be #included before #including lzma.h. On systems
that don't have C99 inttypes.h, it's the problem of the
applications to provide the required types and macros
before #including lzma.h.

If lzma.h defined the missing types and macros, it could
conflict with third-party applications whose configure
has detected that the types are missing and defined them
in config.h already. An alternative would have been
introducing lzma_uint32 and similar types, but that would
just be an extra pain on modern systems.

Lasse Collin 072927905a Rearranged testing of GCC-specific flags. 2008-01-05 19:42:04 +02:00
