2018-04-20Fix error in rustc_driver::test.Michael Woerister-1/+1
2018-04-18Use #[no_debug] to work around LLVM problem with rustc_driver::get_trans::LOAD.Michael Woerister-0/+4
2018-03-31Auto merge of #49201 - Phlosioneer:add-trivial-size-hints, r=SimonSapinbors-0/+7
Implement some trivial size_hints for various iterators This also implements ExactSizeIterator where applicable. Addresses most of the Iterator traits mentioned in #23708. I intend to do more, but I don't want to make the PR too large.
2018-03-29Auto merge of #49313 - sgrif:sg-revert-stuff, r=nikomatsakisbors-2/+1
Remove universes from `ty::ParamEnv` This change was never meant to land. #48407 takes an alternate approach. However, that PR is now blocked on some issues with canonicalization, and rebasing these reverts gets harder each time, so let's just get this bit out of the way now. r? @nikomatsakis
2018-03-28[incremental] Don't panic if decoding the cache failsWesley Wiser-1/+3
If the cached data can't be loaded from disk, just issue a warning to the user so they know why compilation is taking longer than usual but don't fail the entire compilation since we can recover by ignorning the on disk cache. In the same way, if the disk cache can't be deserialized (because it has been corrupted for some reason), report the issue as a warning and continue without failing the compilation. `Decodable::decode()` tends to panic with various errors like "entered unreachable code" or "index out of range" if the input data is corrupted. Work around this by catching panics from the `decode()` calls when joining the thread and continuing without the cached data. Fixes #48847

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.

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

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

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!
