2019-12-14Revert "Stabilize the `never_type`, written `!`."Niko Matsakis-1/+1
This reverts commit 15c30ddd69d6cc3fffe6d304c6dc968a5ed046f1.

2019-12-03Move Session to librustc_sessionMark Rousskov-6/+1
2019-11-27Move ExprUseVisitor and mem_categorization to rustc_typeckMatthew Jasper-2/+0
`MemCategorizationContext` is now private, the remaining types and traits remain public for Clippy.

2019-11-15Rollup merge of #66013 - nnethercote:avoid-hashing-twice-in-get_query, r=ZoxcYuki Okushi-0/+1
Avoid hashing the key twice in `get_query()`. For a single-threaded parallel compiler, this reduces instruction counts across several benchmarks, by up to 2.8%. The commit also adds documentation about `Sharded`'s use of `FxHasher`. r? @Zoxc

2019-11-13Rollup merge of #66335 - Mark-Simulacrum:self-profile-to-data, ↵Yuki Okushi-1/+0
r=michaelwoerister Move self-profile infrastructure to data structures The single dependency on queries (QueryName) can be fairly easily abstracted via a trait and this further decouples Session from librustc (the primary goal). This is intended as a precursor to moving Session out of librustc, but since that involves lots of smaller steps that move around code I'm splitting it up into separate PRs.

2019-10-05Rollup merge of #65105 - Mark-Simulacrum:split-librustc, r=nikomatsakisTyler Mandry-4/+0
Split out some passes from librustc This is just moving them out to librustc_passes -- I've not measured compile time or run time. I don't expect any significant impact, but this seems prudent regardless.
2019-10-05Rollup merge of #64708 - SimonSapin:option-deref, r=CentrilTyler Mandry-1/+0
Stabilize `Option::as_deref` and `Option::as_deref_mut` The tracking issue https://github.com/rust-lang/rust/issues/50264 still has unresolved question for the corresponding `Result` methods.

2019-09-15Auto merge of #60584 - jonas-schievink:ice-panic-hook, r=oli-obkbors-1/+0
Use `panic::set_hook` to print the ICE message This allows custom frontends and backends to override the hook with their own, for example to point people to a different issue tracker. ICE messages are printed in a slightly different order now. Nightly prints: ``` thread 'rustc' panicked at 'called `Option::unwrap()` on a `None` value', src/libcore/option.rs:347:21 note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace. error: aborting due to 2 previous errors Some errors have detailed explanations: E0277, E0658. For more information about an error, try `rustc --explain E0277`. error: internal compiler error: unexpected panic note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports note: rustc 1.36.0-nightly (08bfe1612 2019-05-02) running on x86_64-unknown-linux-gnu ``` After this PR, rustc prints: ``` thread 'rustc' panicked at 'called `Option::unwrap()` on a `None` value', src/libcore/option.rs:347:21 note: Run with `RUST_BACKTRACE=1` environment variable to display a backtrace. error: internal compiler error: unexpected panic note: the compiler unexpectedly panicked. this is a bug. note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports note: rustc 1.36.0-dev running on x86_64-unknown-linux-gnu error: aborting due to 2 previous errors Some errors have detailed explanations: E0277, E0658.

Migrate internal diagnostic registration to macro_rules Review is best done commit-by-commit. Fixes #64132.
2019-09-06Move the HIR cfg to `rustc_ast_borrowck`Matthew Jasper-1/+0
No new code should be using it.

2019-08-30Add a "diagnostic item" schemeOliver Scherer-0/+2
This allows lints and other diagnostics to refer to items by a unique ID instead of relying on whacky path resolution schemes that may break when items are relocated.

2019-07-25Rollup merge of #62735 - petrochenkov:galloc, r=alexcrichtonMazdak Farrokhzad-1/+0
Turn `#[global_allocator]` into a regular attribute macro It was a 99% macro with exception of some diagnostic details. As a result of the change, `#[global_allocator]` now works in nested modules and even in nameless blocks.

2019-07-07rustc: Remove `dylib` crate type from most rustc cratesAlex Crichton-1/+0
Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!
2019-07-05Rollup merge of #61545 - flip1995:internal_lints, r=oli-obkMazdak Farrokhzad-1/+0
Implement another internal lints cc #49509 This adds ~~two~~ one internal lint~~s~~: 1. LINT_PASS_IMPL_WITHOUT_MACRO: Make sure, that the `{declare,impl}_lint_pass` macro is used to implement lint passes. cc #59669 2. ~~USAGE_OF_TYCTXT_AND_SPAN_ARGS: item 2 on the list in #49509~~ ~~With 2. I wasn't sure, if this lint should be applied everywhere. That means a careful review of 0955835 would be great. Also 73fb9b4 allows this lint on some functions. Should I also apply this lint there?~~ TODO (not directly relevant for review): - [ ] https://github.com/rust-lang/rust/pull/59316#discussion_r280186517 (not sure yet, if this works or how to query for `rustc_private`, since it's not in [`Features`](https://doc.rust-lang.org/nightly/nightly-rustc/syntax/feature_gate/struct.Features.html) :thinking: cc @eddyb) - [x] https://github.com/rust-lang/rust/pull/61735#discussion_r292389870 - [x] Check explicitly for the `{declare,impl}_lint_pass!` macros r? @oli-obk
