2019-03-08Rollup merge of #58984 - estebank:multi-treat-err-as-bug, r=oli-obkPietro Albini-3/+3
Teach `-Z treat-err-as-bug` to take a number of errors to emit `-Z treat-err-as-bug` will cause `rustc` to panic after the first error is reported, like previously. `-Z treat-err-as-bug=2` will cause `rustc` to panic after 2 errors have been reported. Fix #58983.

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.

2019-02-27Rename variadic to c_variadicDan Robertson-29/+29
Function signatures with the `variadic` member set are actually C-variadic functions. Make this a little more explicit by renaming the `variadic` boolean value, `c_variadic`.

2019-02-27Rollup merge of #58678 - doctorn:refuse-async-fn-2015-edition, r=varkorMazdak Farrokhzad-22/+46
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

Fix for issue #58050 Hi, a quick PR to mention in the compiler error message that `?` is a macro operator, as according to issue #58050 It passed `python x.py test src/tools/tidy` locally, as well as the recommendation to run `/x.py test src/test/ui --stage 1 --bless`. Let me know if anything else is needed.

2019-02-23Rollup merge of #58526 - pmccarter:master, r=estebankMazdak Farrokhzad-9/+44
Special suggestion for illegal unicode curly quote pairs Fixes #58436 Did not end up expanding the error message span to include the full string literal since I figured the start of the token was the issue, while the help suggestion span would include up to the closing quotation mark. The look ahead logic does not affect the reader position, not sure if that is an issue (if eg it should still continue to parse after the closing quote without erroring out).
