…-parsing, r=GuillaumeGomez rustdoc: use text-based doctest parsing if a macro is wrapping main This is a "forward-port" of rust-lang#57019, intended to get rust-lang#56898 on nightly, since it's now fixed on beta (and already worked on stable). To recap: * The libsyntax-based doctest parsing now checks to see whether there is a top-level macro invocation in the doctest while it's checking for `fn main` and an `extern crate` statement. * If it finds a macro invocation and *didn't* find `fn main`, then it performs the older text-based scan to allow doctests like the ones in `allocator_api` to still compile. A "proper" fix will involve changing how `make_test` works to call it later in the `run_test` function, after the initial steps of compilation have completed. I've filed [a separate issue](rust-lang#57415) for that, though.
