2018-01-01Auto merge of #47098 - estebank:immutable-field, r=nagisabors-2/+2
Reword trying to operate in immutable fields The previous message ("cannot assign/mutably borrow immutable field") when trying to modify a field of an immutable binding gave the (incorrect) impression that fields can be mutable independently of their ADT's binding. Slightly reword the message to read "cannot assign/mutably borrow field of immutable binding". Re #35937.
2018-01-01Auto merge of #47064 - kennytm:force-trailing-newlines, r=estebankbors-9/+5
Add a tidy check for missing or too many trailing newlines. I've noticed recently there are lots of review comments requesting to fix trailing newlines. If this is going to be an official style here, it's better to let the CI do this repetitive check.

2017-12-31Removed unnecessary output of linker options when linker is not installedFelix Schütt-1/+1
It's unnecessary to print the linker options if there is no linker installed. Currently, for libraries, the output is still printed, see #46998 for discussion

Do not expand a derive invocation when derive is not allowed Closes #46655. The first commit is what actually closes #46655. The second one is just a refactoring I have done while waiting on a test.

2017-12-27Auto merge of #46479 - bkchr:termination_trait, r=arielb1bors-3/+23
Implements RFC 1937: `?` in `main` This is the first part of the RFC 1937 that supports new `Termination` trait in the rust `main` function. Thanks @nikomatsakis, @arielb1 and all other people in the gitter channel for all your help! The support for doctest and `#[test]` is still missing, bu as @nikomatsakis said, smaller pull requests are better :)
2017-12-26Auto merge of #46975 - matthewjasper:mir-moveck-asm, r=arielb1bors-1/+103
[MIR Borrowck] Moveck inline asm statements Closes #45695 New behavior: * Input operands to `asm!` are moved, direct output operands are initialized. * Direct, non-read-write outputs match the assignment changes in #46752 (Shallow writes, end borrows).

2017-12-26Do not expand a derive invocation when derive is not allowedSeiichi Uchida-0/+23
1. Change the return type of `expand_invoc()` and its subroutines to `Option<Expansion>` from `Expansion`. 2. Return `None` when expanding a derive invocation if the item cannot have derive on it (in `expand_derive_invoc()`).

2017-12-24Auto merge of #46888 - cramertj:nested-impl-trait-error, r=nikomatsakisbors-2/+41
Add a feature gate for nested uses of `impl Trait` This allows us to delay stabilization of nested `impl Trait` until we have a plan to solve the problem posed [here](https://github.com/rust-lang/rust/issues/34511#issuecomment-350715858). r? @nikomatsakis

Closure type error ui tweak Do not point at the same span on all notes/help messages, and instead show them without a span.
2017-12-22Auto merge of #46838 - pnkfelix:issue-46112-followup, r=estebankbors-12/+32
Followup for #46112. Sorting by crate-num should ensure that we favor `std::foo::bar` over `any_other_crate::foo::bar`. Interestingly, *this* change had a much larger impact on our internal test suite than PR #46708 (which was my original fix to #46112).

Issue #46589 - Kill borrows on a local variable whenever we assign ov… …er this variable This is a first patch for the issue, handling the simple case while I figure out the data structures involved in the more complex cases.
2017-12-22Auto merge of #46732 - estebank:silence-recovered-blocks, r=petrochenkovbors-1/+0
Do not emit type errors on recovered blocks When a parse error occurs on a block, the parser will recover and create a block with the statements collected until that point. Now a flag stating that a recovery has been performed in this block is propagated so that the type checker knows that the type of the block (which will be identified as `()`) shouldn't be checked against the expectation to reduce the amount of irrelevant diagnostic errors shown to the user. Fix #44579.

2017-12-22Rollup merge of #46858 - QuietMisdreavus:external-doc-error, r=estebankkennytm-0/+16
tweaks and fixes for doc(include) This PR makes a handful of changes around `#[doc(include="file.md")]` (https://github.com/rust-lang/rust/issues/44732): * Turns errors when loading files into full errors. This matches the original RFC text. * Makes the `missing_docs` lint check for `#[doc(include="file.md")]` as well as regular `#[doc="text"]` attributes. * Loads files included by `#[doc(include="file.md")]` into dep-info, mirroring the behavior of `include_str!()` and friends. * Adds or modifies tests to check for all of these.
2017-12-22Rollup merge of #46780 - varkor:contrib-5, r=arielb1kennytm-0/+14
Fix ICE when calling non-functions within closures The visitor for walking function bodies did not previously properly handle error-cases for function calls. These are now ignored, preventing the panic. This fixes #46771.

2017-12-21Auto merge of #46877 - Deewiant:gh46843, r=eddybbors-0/+22
MIR: terminate unreachable blocks in construct_const Fixes #46843. #45821 added unreachable blocks in matches, which were terminated in construct_fn but not in construct_const, causing a panic due to "no terminator on block" when constants involved matching on enums. The "unimplemented expression type" error may go away in the future, the key is that we see the E0015 about using a non-const function and then don't ICE.
2017-12-21Auto merge of #46531 - cramertj:no-mo-modrs, r=nikomatsakisbors-4/+30
Implement non-mod.rs mod statements Fixes https://github.com/rust-lang/rust/issues/45385, cc https://github.com/rust-lang/rust/issues/44660 This will fail tidy right now because it doesn't recognize my UI tests as feature-gate tests. However, I'm not sure if compile-fail will work out either because compile-fail usually requires there to be error patterns in the top-level file, which isn't possible with this feature. What's the recommended way to handle this?
2017-12-21Auto merge of #46083 - petrochenkov:morepriv, r=nikomatsakisbors-23/+466
Type privacy polishing Various preparations before implementing https://github.com/rust-lang/rfcs/pull/2145 containing final minor breaking changes (mostly for unstable code or code using `allow(private_in_public)`). (Continuation of https://github.com/rust-lang/rust/pull/42125, https://github.com/rust-lang/rust/pull/44633 and https://github.com/rust-lang/rust/pull/41332.) It would be good to run crater on this. r? @eddyb

nll part 5 Next round of changes from the nll-master branch. Extensions: - we now propagate ty-region-outlives constraints out of closures and into their creator when necessary - we fix a few ICEs that can occur by doing liveness analysis (and the resulting normalization) during type-checking - we handle the implicit region bound that assumes that each type `T` outlives the fn body - we handle normalization of inputs/outputs in fn signatures Not included in this PR (will come next): - handling `impl Trait` - tracking causal information - extended errors r? @arielb1
