They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits.

This flag opts out of the min-const-fn checks entirely, which is usually not what we want. The few cases where the flag is still necessary have been annotated.

2019-08-23bootstrap: Merge the libtest build step with libstdAlex Crichton-0/+3
Since its inception rustbuild has always worked in three stages: one for libstd, one for libtest, and one for rustc. These three stages were architected around crates.io dependencies, where rustc wants to depend on crates.io crates but said crates don't explicitly depend on libstd, requiring a sysroot assembly step in the middle. This same logic was applied for libtest where libtest wants to depend on crates.io crates (`getopts`) but `getopts` didn't say that it depended on std, so it needed `std` built ahead of time. Lots of time has passed since the inception of rustbuild, however, and we've since gotten to the point where even `std` itself is depending on crates.io crates (albeit with some wonky configuration). This commit applies the same logic to the two dependencies that the `test` crate pulls in from crates.io, `getopts` and `unicode-width`. Over the many years since rustbuild's inception `unicode-width` was the only dependency picked up by the `test` crate, so the extra configuration necessary to get crates building in this crate graph is unlikely to be too much of a burden on developers. After this patch it means that there are now only two build phasese of rustbuild, one for libstd and one for rustc. The libtest/libproc_macro build phase is all lumped into one now with `std`. This was originally motivated by rust-lang/cargo#7216 where Cargo was having to deal with synthesizing dependency edges but this commit makes them explicit in this repository.
2019-08-17Serialize additional data for procedural macrosAaron Hill-0/+8
Split off from #62855 This PR deerializes the declaration `Span` and attributes for all procedural macros from their underlying function definitions. This allows Rustdoc to properly render doc comments and source links when inlining procedural macros across crates

2019-06-23Fix meta-variable binding errors in macrosJulien Cretin-3/+3
The errors are either: - The meta-variable used in the right-hand side is not bound (or defined) in the left-hand side. - The meta-variable used in the right-hand side does not repeat with the same kleene operator as its binder in the left-hand side. Either it does not repeat enough, or it uses a different operator somewhere. This change should have no semantic impact.

2019-04-05Use for_each to extend collectionsJosh Stone-3/+1
This updates the `Extend` implementations to use `for_each` for many collections: `BinaryHeap`, `BTreeMap`, `BTreeSet`, `LinkedList`, `Path`, `TokenStream`, `VecDeque`, and `Wtf8Buf`. Folding with `for_each` enables better performance than a `for`-loop for some iterators, especially if they can just forward to internal iterators, like `Chain` and `FlatMap` do.
2019-03-27Auto merge of #55780 - ogoffart:span_source_text, r=petrochenkovbors-0/+13
Introduce proc_macro::Span::source_text A function to extract the actual source behind a Span. Background: I would like to use `syn` in a `build.rs` script to parse the rust code, and extract part of the source code. However, `syn` only gives access to proc_macro2::Span, and i would like to get the source code behind that. I opened an issue on proc_macro2 bug tracker for this feature https://github.com/alexcrichton/proc-macro2/issues/110 and @alexcrichton said the feature should first go upstream in proc_macro. So there it is! Since most of the Span API is unstable anyway, this is guarded by the same `proc_macro_span` feature as everything else.
