buffer lexer errors in rustdoc syntax checking The code isn't ideal (I really would like to display the errors inline), but this at least gets us to where we were before #63017.

Extract `rustc_hir` out of `rustc` The new crate contains: ```rust pub mod def; pub mod def_id; mod hir; pub mod hir_id; pub mod itemlikevisit; pub mod pat_util; pub mod print; mod stable_hash_impls; pub use hir::*; pub use hir_id::*; pub use stable_hash_impls::HashStableContext; ``` Remains to be done in follow-up PRs: - Move `rustc::hir::map` into `rustc_hir_map` -- this has to be a separate crate due to the `dep_graph` (blocked on https://github.com/rust-lang/rust/pull/67761). - Move references to `rustc::hir` to `rustc_hir` where possible. cc https://github.com/rust-lang/rust/issues/65031 r? @Zoxc

2020-01-04Distinguish between private items and hidden items in rustdocDavid Tolnay-73/+108
I believe rustdoc should not be conflating private items (visibility lower than `pub`) and hidden items (attribute `doc(hidden)`). This matters now that Cargo is passing --document-private-items by default for bin crates. In bin crates that rely on macros, intentionally hidden implementation details of the macros can overwhelm the actual useful internal API that one would want to document. This PR restores the strip-hidden pass when documenting private items, and introduces a separate unstable --document-hidden-items option to skip the strip-hidden pass. The two options are orthogonal to one another.

`make_test` is also called when parsing codeblocks for the playground links so it should handle unwinds from the parser internally.
2020-01-04Rollup merge of #67709 - petrochenkov:nodedup2, r=CentrilDylan DPC-41/+13
Introduce an option for disabling deduplication of diagnostics With the intent of using it in UI tests (https://github.com/rust-lang/rust/pull/67122). The option is boolean (`-Z deduplicate-diagnostics=yes/no`) and can be specified multiple times with later values overriding earlier values (`-Z deduplicate-diagnostics=no -Z deduplicate-diagnostics=yes` == `-Z deduplicate-diagnostics=yes`), so it can be set in a hierarchical way, e.g. UI testing infra may disable the deduplication by default with specific tests being able to enable it back.

2019-12-31Rollup merge of #67735 - petrochenkov:uibool, r=Mark-SimulacrumDylan DPC-3/+3
Support `-Z ui-testing=yes/no` `ui-testing` is now a boolean option (`-Z ui-testing=yes/no`) and can be specified multiple times with later values overriding earlier values (`-Z ui-testing=yes -Z ui-testing=no` == `-Z ui-testing=no`), so it can be set in a hierarchical way, e.g. UI testing infra may enable it by default with specific tests being able to opt-out. This way we can remove the special opt-out support from `compiletest`. Inspired by https://github.com/rust-lang/rust/pull/67709.

Allocate HIR on an arena 4/4 This is the fourth and last PR in the series started by #66931, #66936 and #66942. The last commits should compile on their own.

2019-12-24Deprecate Error::description for realDavid Tolnay-5/+1
`description` has been documented as soft-deprecated since 1.27.0 (17 months ago). There is no longer any reason to call it or implement it. This commit: - adds #[rustc_deprecated(since = "1.41.0")] to Error::description; - moves description (and cause, which is also deprecated) below the source and backtrace methods in the Error trait; - reduces documentation of description and cause to take up much less vertical real estate in rustdocs, while preserving the example that shows how to render errors without needing to call description; - removes the description function of all *currently unstable* Error impls in the standard library; - marks #[allow(deprecated)] the description function of all *stable* Error impls in the standard library; - replaces miscellaneous uses of description in example code and the compiler.

Results show too much Fixes #67461. To reproduce the current issue: search anything, then once the results appears, press escape. They should disappear then re-appear right away. This is because blurring an element triggers the "change" event. r? @kinnison

Rustdoc mutability removal Fixes #67470. As discussed in another PR, the `clean::Mutability` type in rustdoc is useless. So let's remove it! r? @Centril
2019-12-22Rollup merge of #66877 - skinny121:const-eval-entry-points, r=oli-obkMazdak Farrokhzad-18/+2
Add simpler entry points to const eval for common usages. I found the `tcx.const_eval` API to be complex/awkward to work with, because of the inherent complexity from all of the different situations it is called from. Though it mainly used in one of the following ways: - Evaluates the value of a constant without any substitutions, e.g. evaluating a static, discriminant, etc. - Evaluates the value of a resolved instance of a constant. this happens when evaluating unevaluated constants or normalising trait constants. - Evaluates a promoted constant. This PR adds three new functions `const_eval_mono`, `const_eval_resolve`, and `const_eval_promoted` to `TyCtxt`, which each cater to one of the three ways `tcx.const_eval` is normally used.

Allocate HIR on an arena 1/4 This PR is the first in a series of 4, aiming at allocating the HIR on an arena, as a memory optimisation. 1. This first PR lays the groundwork and migrates some low-hanging fruits. 2. The second PR will migrate `hir::Expr`, `hir::Pat` and related. 3. The third PR will migrate `hir::Ty` and related. 4. The final PR will be dedicated to eventual cleanups. In order to make the transition as gradual as possible, some lowering routines receive `Box`-allocated data and move it into the arena. This is a bit wasteful, but hopefully temporary. Nonetheless, special care should be taken to avoid double arena allocations. Work mentored by @Zoxc.
