Update tests 2019-08-30 00:46:25 +00:00			`#[rustc_diagnostic_item = "foomp"] //~ ERROR compiler internal support for linting`
Add a "diagnostic item" scheme This allows lints and other diagnostics to refer to items by a unique ID instead of relying on whacky path resolution schemes that may break when items are relocated. 2019-05-19 18:16:04 +00:00			`struct Foomp;`
Provide a span if main function is not present in crate Unfortunately, the diagnotic machinery does not cope well with an empty span which can happen if the crate is empty, in which case we merely set a spanless note. 2019-09-08 17:06:49 +00:00			`fn main() {}`
