[PATCH] D55045: Add a version of std::function that includes a few optimizations.

[Jordan Soyke via Phabricator]

jsoyke added a comment.

Heres another version that might be worth discussing.  It's a much simpler implementation because it doesn't attempt small value optimization for non-trivial objects, this makes operations like move-construction very fast.

Here is a paste of the benchmark comparison: https://pastebin.com/raw/pLrevUAc

I've had both implementations laying around for a while, but some analysis that I did today suggests that the current version (without the non-trivial SOO) might be better for some important workloads.
