[Bug gcov-profile/110827] C++20 coroutines aren't being measured by gcov

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110827 --- Comment #10 from Michael Duggan --- To sum up what I have figured out, C++ transforms the coroutine "function" into a trio of functions: a ramp function, an actor function, and a destruction function. The ramp function acts as the actual fu

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110827 --- Comment #9 from Michael Duggan --- More data: The coroutine actor is marked as artificial in coro_build_actor_or_destroy_function. As a result, it is completely ignored by gcov. In gcov's process_all_functions function, artificial function

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110827 --- Comment #8 from Michael Duggan --- Using the better test case, I have determined that the coroutine _is_ being instrumented with gcov counters. When disassembled, the output contains the following in the bar() actor function: Dump of assem

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=110827 --- Comment #4 from Michael Duggan --- I should be more explicit. The `std::cout` line in the example is just a placeholder for "does some work here," and this example is specifically the simplest version of a coroutine I could come up with tha
