Description

Helpers and wrappers so simplify usage of microbenchmark.hpp.

Notably the benchmark functions expect the actual »test subject« as a function or lambda with signature size_t(size_t). The argument will be the loop index and the result value will be added into a checksum, which also ensures that the optimiser can not unroll the benchmark loop. However, in practical use this strict requirement for the signature turned out as a nuisance; this header provides some automatic adaption

• accept any numeric type as argument
• accept any numeric type as checksum contribution (cast to size_t)
• accept signature void(void)
