2020-06-08Don't lose empty `where` clause when pretty-printingAaron Hill-1/+5
Previously, we would parse `struct Foo where;` and `struct Foo;` identically, leading to an 'empty' `where` clause being omitted during pretty printing. This will cause us to lose spans when proc-macros involved, since we will have a collected `where` token that does not appear in the pretty-printed item. We now explicitly track the presence of a `where` token during parsing, so that we can distinguish between `struct Foo where;` and `struct Foo;` during pretty-printing

2020-05-21Auto merge of #70705 - lcnr:generic_discriminant, r=nikomatsakisbors-70/+10
Use `T`'s discriminant type in `mem::Discriminant<T>` instead of `u64`. fixes #70509 Adds the lang-item `discriminant_kind`. Updates the function signature of `intrinsics::discriminant_value`. Adds the *probably permanently unstable* trait `DiscriminantKind`. `mem::Discriminant` should now be smaller in some cases. r? @ghost

expand: Implement something similar to `#[cfg(accessible(path))]` cc https://github.com/rust-lang/rust/issues/64797 The feature is implemented as a `#[cfg_accessible(path)]` attribute macro rather than as `#[cfg(accessible(path))]` because it needs to wait until `path` becomes resolvable, and `cfg` cannot wait, but macros can wait. Later we can think about desugaring or not desugaring `#[cfg(accessible(path))]` into `#[cfg_accessible(path)]`. This implementation is also incomplete in the sense that it never returns "false" from `cfg_accessible(path)`, it requires some tweaks to resolve, which is not quite ready to answer queries like this during early resolution. However, the most important part of this PR is not `cfg_accessible` itself, but expansion infrastructure for retrying expansions. Before this PR we could say "we cannot resolve this macro path, let's try it later", with this PR we can say "we cannot expand this macro, let's try it later" as well. This is a pre-requisite for - turning `#[derive(...)]` into a regular attribute macro, - properly supporting eager expansion for macros that cannot yet be resolved like ``` fn main() { println!(not_available_yet!()); } macro_rules! make_available { () => { #[macro_export] macro_rules! not_available_yet { () => { "Hello world!" } }} } make_available!(); ```
