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.
