2019-01-21Rollup merge of #57769 - estebank:cast-suggestion-struct-field, r=matthewjasperMazdak Farrokhzad-12/+132
Suggest correct cast for struct fields with shorthand syntax ``` error[E0308]: mismatched types --> $DIR/type-mismatch-struct-field-shorthand.rs:8:19 | LL | let _ = RGB { r, g, b }; | ^ expected f64, found f32 help: you can cast an `f32` to `f64` in a lossless way | LL | let _ = RGB { r: r.into(), g, b }; | ^^^^^^^^^^^ ``` Fix #52497.

Continue parsing after parent type args and suggest using angle brackets ``` error[E0214]: parenthesized parameters may only be used with a trait --> $DIR/E0214.rs:2:15 | LL | let v: Vec(&str) = vec!["foo"]; | ^^^^^^ | | | only traits may use parentheses | help: use angle brackets instead: `<&str>` ``` r? @zackmdavis
2019-01-21Rollup merge of #56796 - KrishnaSannasi:try_from_impl_change, r=shepmasterMazdak Farrokhzad-3/+40
Change bounds on `TryFrom` blanket impl to use `Into` instead of `From` This is from this [comment](https://github.com/rust-lang/rust/issues/33417#issuecomment-447111156) I made. This will expand the impls available for `TryFrom` and `TryInto`, without losing anything in the process.

2019-01-20Remove unnecessary dummy span checksEsteban Küber-18/+24
The emitter already verifies wether a given span note or span label can be emitted to the output. If it can't, because it is a dummy span, it will be either elided for labels or emitted as an unspanned note/help when applicable.

This commit adds a `help: consider dereferencing the boxed value` suggestion to discriminants of match statements when the match arms have type `T` and the discriminant has type `Box<T>`.

2019-01-20Auto merge of #56884 - euclio:codeblock-diagnostics, r=QuietMisdreavusbors-131/+562
rustdoc: overhaul code block lexing errors Fixes #53919. This PR moves the reporting of code block lexing errors from rendering time to an early pass, so we can use the compiler's error reporting mechanisms. This dramatically improves the diagnostics in this situation: we now de-emphasize the lexing errors as a note under a warning that has a span and suggestion instead of just emitting errors at the top level. Additionally, this PR generalizes the markdown -> source span calculation function, which should allow other rustdoc warnings to use better spans in the future. Last, the PR makes sure that the code block is always emitted in the docs, even if it fails to highlight correctly. Of note: - The new pass unfortunately adds another pass over the docs to gather the doc blocks for syntax-checking. I wonder if this could be combined with the pass that looks for testable blocks? I'm not familiar with that code, so I don't know how feasible that is. - `pulldown_cmark` doesn't make it easy to find the spans of the code blocks, so the code that calculates the spans is a little nasty. It works for all the test cases I threw at it, but I wouldn't be surprised if an edge case would break it. Should have a thorough review. - This PR worsens the state of #56885, since those certain fatal lexing errors are now emitted before docs get generated at all.
2019-01-20const_eval: Predetermine the layout of all locals when pushing a stack frameBjörn Steinbrink-18/+24
Usually the layout of any locals is required at least three times, once when it becomes live, once when it is written to, and once it is read from. By adding a cache for them, we can reduce the number of layout queries speeding up code that is heavy on const_eval.

2019-01-20Auto merge of #57697 - dotdash:fast_lex_reg_resol_item_bodies, r=nagisabors-6/+8
Use a faster early exit during region expansion Turns out that the equality check for regions is rather expensive, and the current early exit check works in such a way, that the comparison is even done twice. As we only really care about the case of equal scopes, we can perform a faster, more specialized check and move it up one level, so we can eventually skip the additional full comparison as well.

[rustbuild] Rebuild std after changes to codegen backends Use `clear_if_dirty` on std for backend changes, just as we do for changes to rustc itself, so new codegen is correctly applied to all later compiler stages. Fixes #48298.

OSX: fix #57534 registering thread dtors while running thread dtors r? @alexcrichton - "fast" `thread_local` destructors get run even on the main thread - "fast" `thread_local` dtors, can initialize other `thread_local`'s One corner case where this fix doesn't work, is when a C++ `thread_local` triggers the initialization of a rust `thread_local`. I did not add any std::thread specific flag to indicate that the thread is currently exiting, which would be checked before registering a new dtor (I didn't really know where to stick that). I think this does the trick tho! Let me know if anything needs tweaking/fixing/etc. resolves this for macos: https://github.com/rust-lang/rust/issues/28129 fixes: https://github.com/rust-lang/rust/issues/57534

Attempt to recover from parse errors while parsing a struct's literal fields by skipping tokens until a comma or the closing brace is found. This allows errors in other fields to be reported.
