| | * lz4c legacy commands are now enabled at runtime based on link/binary name "lz4c"Yann Collet2017-08-143-38/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | instead of selected at compilation time depending on a macro. This design makes it possible to have a single binary which supports both modes. An advantageous side effect is that when doing `make; make install` no additional binary is created during `make install` (it used to create `lz4c`, because `make` would only build `lz4`)

| * 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 #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.
