In order to minimize the verbosity of common syntax errors that are parsed as type ascription, hide the feature gate error unless there are no other errors being emitted by the parser.

2019-03-16Rollup merge of #59169 - tmandry:allow-features-flag, r=cramertjkennytm-1/+10
Add `-Z allow_features=...` flag Adds a compiler option to allow only whitelisted features. For projects on nightly that want to prevent feature-creep (and maybe, someday, move off of nightly). Not being able to enforce this has been a problem on Fuchsia and at other big companies. This doesn't support filtering edition feature flags, but someone is welcome to add that if they need it.

Support defining C compatible variadic functions ## Summary Add support for defining C compatible variadic functions in unsafe rust with `extern "C"` according to [RFC 2137]. ## Details ### Parsing When parsing a user defined function that is `unsafe` and `extern "C"` allow variadic signatures and inject a "spoofed" `VaList` in the new functions signature. This allows the user to interact with the variadic arguments via a `VaList` instead of manually using `va_start` and `va_end` (See [RFC 2137] for details). ### Codegen When running codegen for a variadic function, remove the "spoofed" `VaList` from the function signature and inject `va_start` when the arg local references are created for the function and `va_end` on return. ## TODO - [x] Get feedback on injecting `va_start/va_end` in MIR vs codegen - [x] Properly inject `va_end` - It seems like it should be possible to inject `va_end` on the `TerminatorKind::Return`. I just need to figure out how to get the `LocalRef` here. - [x] Properly call Rust defined C variadic functions in Rust - The spoofed `VaList` causes problems here. Related to: #44930 r? @ghost [RFC 2137]: https://github.com/rust-lang/rfcs/blob/master/text/2137-variadic.md

2019-02-27Rollup merge of #58678 - doctorn:refuse-async-fn-2015-edition, r=varkorMazdak Farrokhzad-1/+1
Deny `async fn` in 2015 edition This commit prevents code using `async fn` from being compiled in Rust 2015 edition. Compiling code of the form: ```rust async fn foo() {} ``` Will now result in the error: ``` error[E0670]: `async fn` is not permitted in the 2015 edition --> async.rs:1:1 | 1 | async fn foo() {} | ^^^^^ error: aborting due to error For more information about an error, try `rustc --explain E0670`. ``` This resolves #58652 and also resolves #53714. r? @varkor

Rename rustc_errors dependency in rust 2018 crates I think this is a better solution than `use rustc_errors as errors` in `lib.rs` and `use crate::errors` in modules. Related: rust-lang/cargo#5653 cc #58099 r? @Centril

Cosmetic improvements to doc comments This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase). r? @steveklabnik Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

2019-02-07Auto merge of #57998 - niklasf:align-enum, r=nagisabors-0/+14
Allow #[repr(align(x))] on enums (#57996) Tracking issue: #57996 Implements an extension of [RFC 1358](https://github.com/rust-lang/rfcs/blob/master/text/1358-repr-align.md) behind a feature flag (`repr_align_enum`). Originally introduced here for structs: #39999. It seems like only HIR-level changes are required, since enums are already aware of their alignment (due to alignment of their limbs). cc @bitshifter
