2009-02-02Updated the x86 assembler code:Lasse Collin1-6/+0
- 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.
2008-12-31Bumped version to 4.999.8beta right after the releaseLasse Collin1-1/+1
of 4.999.7beta.
2008-12-31Disable both Subblock encoder and decoder my default,Lasse Collin1-1/+1
since they are not finished and may have security issues too.
2008-12-31Prepare for 4.999.7beta release.Lasse Collin1-2/+2
2008-12-31Fixed missing quoting in configure.ac.Lasse Collin1-19/+19
2008-12-31Remove lzma_init() and other init functions from liblzma API.Lasse Collin1-5/+24
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.
2008-12-13Name the package "xz" in configure.ac.Lasse Collin1-7/+4
2008-12-12Some adjustments to GCC warning flags. The important changeLasse Collin1-3/+5
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.
2008-11-19Added missing check for uint16_t.Lasse Collin1-0/+1
2008-11-19Renamed lzma to xz and lzmadec to xzdec. We create symlinksLasse Collin1-2/+2
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.
2008-11-19Oh well, big messy commit again. Some highlights:Lasse Collin1-12/+36
- 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
2008-09-27Some API changes, bug fixes, cleanups etc.Lasse Collin1-9/+9
2008-09-10Bumped version to 4.999.6alpha.Lasse Collin1-1/+1
2008-08-28Sort of garbage collection commit. :-| Many things are stillLasse Collin1-169/+187
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.
2008-06-18Update the code to mostly match the new simpler file formatLasse Collin1-8/+33
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.
2008-05-11Remove support for pre-C89 libc versions that lack memcpy,Lasse Collin1-1/+1
memmove, and memset.
2008-05-11Improved C99 compiler detection in configure.ac. It willLasse Collin1-12/+12
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().
2008-04-25Bumped version number to 4.999.3alpha. It will become 5.0.0Lasse Collin1-2/+2
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.
2008-03-24Replaced the range decoder optimization that used arithmeticLasse Collin1-1/+0
right shift with as fast version that doesn't need arithmetic right shift. Removed the related check from configure.ac.
2008-03-22Added autoconf check to detect if we can use arithmeticLasse Collin1-0/+1
right shift for optimizations.
2008-01-18Added the debug directory and the first debug toolLasse Collin1-0/+1
(sync_flush). These tools are not built unless the user runs "make" in the debug directory.
2008-01-18Don't add -g to CFLAGS when --enable-debug is specified.Lasse Collin1-1/+0
It's the job of the user to put that in CFLAGS.
2008-01-15Fixed assembler detection in configure.ac, and addedLasse Collin1-16/+16
detection for x86_64.
2008-01-09Define HAVE_ASM_X86 when x86 assembler optimizations areLasse Collin1-1/+4
used. This #define will be useful for inline assembly.
2008-01-07Test for $GCC = yes instead of if it is non-empty. ThisLasse Collin1-1/+1
way it is possible to use ac_cv_c_compiler_gnu=no to force configure to think it is using non-GNU C compiler.
2008-01-06Cosmetic changes to configure.ac.Lasse Collin1-8/+6
2008-01-06Automatically disable assembler code on Darwin x86.Lasse Collin1-2/+15
Darwin has different ABI than GNU+Linux and Solaris, thus the assembler code doesn't assemble on Darwin.
2008-01-06Introduced compatibility with systems that have pre-C99Lasse Collin1-1/+12
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.
