* 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).
* update bench.c to use less time invocationsYann Collet2018-02-201-9/+9

| * | | Ensure LZ4_DEPRECATED("...") is before LZ4LIB_APIAsger Hautop Drewsen2018-01-312-31/+31
|/ / / | | | | | | | | | | | | | | | When using clang++ with std c++14 or c++17 you would get the error "an attribute list cannot appear here" when including "lz4.h" as the visibility attribute is before the c++ attribute. This ensures that the [[deprecated]] c++ attribute is before everything else in the function declarations.
