* tried to clean another bunch of cppcheck warningsYann Collet2018-09-191-4/+5
| | | | | | | | | | | | so "funny" thing with cppcheck is that no 2 versions give the same list of warnings. On Mac, I'm using v1.81, which had all warnings fixed. On Travis CI, it's v1.61, and it complains about a dozen more/different things. On Linux, it's v1.72, and it finds a completely different list of a half dozen warnings. Some of these seems to be bugs/limitations in cppcheck itself. The TravisCI version v1.61 seems unable to understand %zu correctly, and seems to assume it means %u.

| | | | | | | | | | | | 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.

| * 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.
