2019-05-13add impl_trait_in_bindings to INCOMPLETE_FEATURESPulkit Goyal-0/+1

Because it's going to be used a lot.
2019-05-07Auto merge of #60586 - cramertj:await, r=oli-obkbors-0/+18
Implement built-in await syntax Adds support for .await under the existing async_await feature gate. Moves macro-like await! syntax to the await_macro feature gate. Removes support for `await` as a non-keyword under the `async_await` feature. This new syntax is not final, but is the consensus solution proposed by the lang team, as explained in https://boats.gitlab.io/blog/post/await-decision/ Fix https://github.com/rust-lang/rust/issues/51719 Fix https://github.com/rust-lang/rust/issues/51751 Fix https://github.com/rust-lang/rust/issues/60016

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

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
