* Fix "use of" uninitialized memory in benchmark.Eric Fiselier2018-11-131-1/+1
| | | | | | | An argument to DoNotOptimize was not fully initialized, which caused msan to complain. llvm-svn: 346808
* Add benchmarks for std::function.Samuel Benzaquen2018-10-121-0/+232
Summary: Benchmarks for construct, copy, move, swap, destroy and invoke, with 8 different input states. For the cases that matter, it tests with and without allowing constant value propagation from construction into the operation tested. This also adds helper functions to generate the cartesian product of different configurations and generate benchmarks for all of them.
