2018-03-16Rollup merge of #48706 - ehuss:main-not-found-in-crate, r=estebankkennytm-1/+1
Add crate name to "main function not found" error message. Fixes #44798 and rust-lang/cargo#4948. I was wondering if it might be cleaner to update the ui tests to add a simple `fn main() {}` for the unrelated tests. Let me know if you would prefer that.
2018-03-14Auto merge of #47630 - canndrew:exhaustive-patterns, r=nikomatsakisbors-5/+5
Stabilise feature(never_type). Introduce feature(exhaustive_patterns) This stabilizes `!`, removing the feature gate as well as the old defaulting-to-`()` behavior. The pattern exhaustiveness checks which were covered by `feature(never_type)` have been moved behind a new `feature(exhaustive_patterns)` gate.

fix #48816 don't print help on indirect compiler ICE https://github.com/rust-lang/rust/issues/48816#issuecomment-372817573
2018-03-15Rollup merge of #48765 - Phlosioneer:10234-wall-help-message, r=estebankkennytm-0/+16
Add info message for -Wall command Users coming from other languages (namely C and C++) often expect to use a -Wall flag. Rustc doesn't support that, and previously it simply printed that it didn't recognize the "all" lint. This change makes rustc print out a help message, explaining: - Why there is no -Wall flag - How to view all the available warnings - Point out that the most commonly used warning is -Wunused - Instead of using a command-line flag, the user should consider a !#[warn(unused)] directive in the root of their crate. I tried to keep the language consistent with the other usage help. Comment if I should change anything. closes #10234, if accepted.

Types will no longer default to `()`, instead always defaulting to `!`. This disables the associated warning and removes the flag from TyTuple

It is backed by the new `normalize_projection_ty` query, which uses canonicalization.
2018-03-13refactor `ParamEnv::empty(Reveal)` into two distinct methodsNiko Matsakis-2/+2
- `ParamEnv::empty()` -- does not reveal all, good for typeck - `ParamEnv::reveal_all()` -- does, good for trans - `param_env.with_reveal_all()` -- converts an existing parameter environment

The reference to -Wunused was removed, and some phrasing was changed.

2018-03-06Update env_logger to 0.5.4Alex Crichton-2/+2
It looks like this cuts down on the number of dependencies in env_logger and notably cuts out a difference between a shared dependency of rls/cargo. My goal here is to ensure that when we compile the RLS/Cargo on CI we only compile Cargo once, and this is one step towards that!

2018-02-28Rollup merge of #48266 - pietroalbini:report-compiler-flags-on-ice, ↵kennytm-5/+80
r=michaelwoerister Report non-standard compile flags on ICE Some ICEs (such as the recent #48248) only happens when a non-standard compiler flag is provided to rustc, but users don't always report the used flags. This can slow down reproducing the issue, so this PR shows all the non-standard compiler flags in the ICE error message. For example, the output of #48248 with this PR is: ``` error: internal compiler error: [...] thread 'rustc' panicked at [...] note: Run with `RUST_BACKTRACE=1` for a backtrace. note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: [...] note: rustc 1.25.0-dev running on x86_64-unknown-linux-gnu note: compiler flags: -C link-dead-code ``` ### Open questions * At the moment, only `-C` and `-Z` flags are shown by default, and all the ones provided by cargo in a standard build are ignored: I did this to only show the flags that probably caused the ICE, and to remove some noise from the message. This removed flags like `opt-level` and `debuginfo` though, could those be useful for reproducing ICEs?
2018-02-24Rollup merge of #48452 - varkor:unpacked-kind, r=eddybManish Goregaokar-4/+4
Introduce UnpackedKind This adds an `UnpackedKind` type as a typesafe counterpart to `Kind`. This should make future changes to kinds (such as const generics!) more resilient, as the type-checker will be able to catch more potential issues. r? @eddyb cc @yodaldevoid
