Additional context
I have found this resource explaining what -fsanitize-coverage=4 means from
clang cpp flags:
Original semantics of -fsanitize-coverage flag is preserved:
* -fsanitize-coverage=0 disables the coverage
* -fsanitize-coverage=1 is a synonym for -fsanitize-coverage=func
* -fsanitize-coverage=2 is a synonym for -fsanitize-coverage=bb
* -fsanitize-coverage=3 is a synonym for -fsanitize-coverage=edge
* -fsanitize-coverage=4 is a synonym for -fsanitize-coverage=edge,indirect-calls
I am not sure what -fsanitize-coverage=edge,indirect-calls is used for.
