* | Allow to predefine FORCE_INLINE macro.Alex Deymo2017-08-072-20/+32
|/ | | | | | | | | | | FORCE_INLINE macro is defined based on the compiler used. When using gcc, it will include "__attribute__((always_inline))" forcing gcc to always inline all the functions marked as FORCE_INLINE. However, this can cause a performance degradation of about 15%. This patch allows to set the FORCE_INLINE macro from the compiler command line to either "static" or "static inline" giving allowing it to inline functions as needed when performing optimizations.
* Fix typos preventing installation of static lib.Ido Rosen2017-08-011-1/+2

* fix #369Yann Collet2017-06-262-1/+18
| | | | | | | | | | | | | | The bug would make the bt search read one byte in an invalid memory region, and make a branch decision based on its value. Impact was small (missed compression opportunity). It only happens in -BD mode, with extDict-prefix overlapping matches. The bt match search is supposed to work also in extDict mode. In which case, the match ptr can point into Dict. When the match was overlapping Dict<->Prefix, match[matchLength] would end up outside of Dict, in an invalid memory area. The correction ensures that in such a case, match[matchLength] ends up at intended location, inside prefix.
* Fix gcc7 Wimplicit-fallthrough warningsChocobo12017-06-192-4/+4
| | | | | For the default Wimplicit-fallthrough=3 level, the comment should start with "fall*"
* made level 10 a bit fasterYann Collet2017-06-141-6/+7

* changed macro HEAPMODE into LZ4_HEAPMODEYann Collet2017-05-022-13/+14
| | | | | | | This macro is susceptible to be triggered from user side typically through compiler flag (-DLZ4_HEAPMODE=1). In which case, it makes sense to prefix the macro since we want to reduce potential side-effect on namespace.
* lz4hc.c: clamp compression levels > 12Alexey Tourbin2017-04-291-0/+2
| | | | | | | | | | | | | | | I noticed that, while 'lz4 -12' works fine, 'lz4 -13' does not compress at all. $ cat </etc/passwd |wc -c 2565 $ lz4 -12 </etc/passwd |wc -c 1456 $ lz4 -13 </etc/passwd |wc -c 2584 Perhaps the best way to fix this is to clamp the compression level in the LZ4HC_compress_generic routine.
