1 | |
| 2 | - include a workaround for a compiler bug on 64 bit windows |
2 | - fixed hash calculation in C♯ version (Tiago Freitas Leal). |
|
|
3 | - unroll copy for small sizes, use memcpy for larger sizes, |
|
|
4 | greatly speeding up decompression in most cases. |
|
|
5 | - finally disable rep movsb - it's a big loss on modern intel cpus, |
|
|
6 | and only a small win on amd cpus. |
|
|
7 | - improve c++ compatibility of the code. |
|
|
8 | - slightly improve compressor speed. |
|
|
9 | - halved memory requirements for compressor on 64 bit architectures, |
|
|
10 | which can improve the speed quite a bit on older cpus. |

17 | - the fix from 3.3 introduced a compression bug, which is fixed in |
