| | | | | | | | | | | | | | | | | | | | | | | | | | | | it was a fairly complex scenario, involving source files > 64K and some extraordinary conditions related to specific layout of ranges of zeroes. and only on level 9.

|/ / / | | | | | | | | | | | | | | | | | | | | | make a round trip test with arbitrary input file, generate an `abort()` on error, to work in tandem with `afl`. note : currently locked on level 9, to investigate #560.

| | | | | | | | | | | | | | | | | | | | | | | | When cross-compiling for example from Darwin to Linux it might be useful to override uname output to force Linux and create Linux libraries instead of Darwin libraries.

| | | | | | | | | | | | | | | which measurably improves speed on levels 9+
| * | lz4hc: fixed PA / SC parameter orderYann Collet2018-05-051-5/+5
| | | | | | | | | | | | | | | | | | also : reserved PA for levels 9+ (instead of 8+). In most cases, speed is lower, and compression benefit is not worth.
| * | lz4hc: SC only enabled for opt parserYann Collet2018-05-051-7/+7
| | | | | | | | | | | | | | | the trade off is not good for regular HC parser : compression is a little bit better, but speed cost is too large in comparison.
| * | fixed SC.opt integration with regular HC parserYann Collet2018-05-051-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | Only enabled when searching forward. note : it slighly improves compression ratio, but measurably decreases speed. Trade-off to analyse.
| * | lz4hc: fixed performance issueYann Collet2018-05-051-114/+20
| | | | | | | | | | | | when combining both PA and CS optimizations
| * | integrated chain swapper into HC match finderYann Collet2018-05-051-45/+76
| | | | | | | | | | | | | | | | | | | | | slower than expected Pattern analyzer and Chain Swapper work slower when both activated. Reasons unclear.
| * | implemented search acceleratorYann Collet2018-05-031-2/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | greatly improves speed compared to non-accelerated, especially for slower files. On my laptop, -b12 : ``` calgary.tar : 4.3 MB/s => 9.0 MB/s enwik7 : 10.2 MB/s => 13.3 MB/s silesia.tar : 4.0 MB/s => 8.7 MB/s ``` Note : this is the simplified version, without handling dictionaries, external buffer, nor pattern analyzer. Current `dev` branch on these samples gives : ``` calgary.tar : 4.2 MB/s enwik7 : 9.7 MB/s silesia.tar : 3.5 MB/s ``` interestingly, it's slower, presumably due to handling of dictionaries.
| * | created LZ4HC_FindLongestMatch()Yann Collet2018-05-031-16/+88
| | | | | | | | | | | | | | | | | | simplified match finder only searching forward and within current buffer, for easier testing of optimizations.
