* tried to clean another bunch of cppcheck warningsYann Collet2018-09-191-16/+24
| | | | | | | | | | | | 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.

* ensure bench speed measurement is more accurate for small inputsYann Collet2018-02-202-24/+41
| | | | | | | | | | | | Previous method would produce too many time() invocations, becoming a significant fraction of workload measured. The new strategy is to use time() only once per batch, and dynamically resize batch size so that each round lasts approximately 1 second. This only matters for small inputs. Measurement for large files (such as silesia.tar) are much less impacted (though decoding speed is so fast that even medium-size files will notice an improvement).
