The ability to print a specific item as identified by NodeId or path seems not particularly useful, and certainly carries quite a bit of complexity with it.
Fixesrust-lang#66476 by turning the violating example into an explicit counterexample.
…rochenkov *Syntactically* permit visibilities on trait items & enum variants Fixesrust-lang#65041 Suppose we have `$vis trait_item` or `$vis enum_variant` and `$vis` is a `:vis` macro fragment. Before this PR, this would fail to parse. This is now instead allowed as per language team consensus in rust-lang#65041 (comment). (See added tests for elaboration.) Moreover, we now also permit visibility modifiers on trait items & enum variants *syntactically* but reject them with semantic checks (in `ast_validation`): ```rust #[cfg(FALSE)] trait Foo { pub fn bar(); } // OK #[cfg(FALSE)] enum E { pub U } // OK ```
Document pitfall with `impl PartialEq<B> for A` Fixesrust-lang#66476 by turning the violating example into an explicit counterexample.
Remove pretty printing of specific nodes in AST The ability to print a specific item as identified by NodeId or path seems not particularly useful, and certainly carries quite a bit of complexity with it. This is intended to simplify our CLI parsing a bit and remove a non-uncomplicated piece of it; I largely did this to remove the dependency on NodeId from librustc/session but it's not really necessary to do so in this invasive a way. The alternative is moving it to librustc_interface or driver, probably.
…t, r=oli-obk Handle statics in MIR as const pointers This is the first PR towards the goal of removing `PlaceBase::Static`. In this PR: * Statics are lowered to dereferencing a const pointer. * The temporaries holding such pointers are tracked in MIR, for the most part this is only used for diagnostics. There are two exceptions: * The borrow checker has some checks for thread-locals that directly use this data. * Const checking will suppress "cannot dereference raw pointer" diagnostics for pointers to `static mut`/`extern static`. This is to maintain the current behaviour (12 tests fail otherwise). The following are left to future PRs (I think that @spastorino will be working on the first 3): * Applying the same treatments to promoted statics. * Removing `PlaceBase::Static`. * Replacing `PlaceBase` with `Local`. * Moving the ever growing collection of metadata that we have for diagnostics in MIR passes somewhere more appropriate. r? @oli-obk

…=Dylan-DPC Error code's long explanation cleanup Continuing to clean up the error code's long explanation. r? @Dylan-DPC
fix reoccuring typo: dereferencable -> dereferenceable
…etrochenkov resolve: more declarative `fresh_binding` Following up on rust-lang#64111, this PR redefines `fresh_binding` wrt. `already_bound_and` and `already_bound_or` in a more declarative and simplified fashion. cc rust-lang#54883 r? @petrochenkov
