C++ Coroutines: Under the covers

by Gor Nishanov

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Coroutines feel like magic. Functions that can suspend and resume in the middle of the execution without blocking a thread! We will look under the covers to see what transformations compilers perform on coroutines, what happens when a coroutine is started, suspended, resumed or cancelled. We will look at optimizations that can make a coroutine disappear into thin air.
