compiletest: Support matching diagnostics on lines below Using `//~vvv ERROR`. This is not needed often, but it's easy to support, and it allows to eliminate a class of `error-pattern`s that cannot be eliminated in any other way. See the diff for the examples of such patterns coming from parser. Some of them can be matched by `//~ ERROR` or `//~^ ERROR` as well (when the final newline is allowed), but it changes the shape of reported spans, so I chose to keep the spans by using `//~v ERROR`. |
