2020-08-19Auto merge of #74098 - GuillaumeGomez:doc-alias-checks, r=ollie27bors-2/+24
Doc alias checks: ensure only items appearing in search index can use it Following the discussion in #73721, I added checks to ensure that only items appearing in the search are allowed to have doc alias. r? @ollie27

2020-08-08Eliminate the `SessionGlobals` from `librustc_ast`.Nicholas Nethercote-14/+13
By moving `{known,used}_attrs` from `SessionGlobals` to `Session`. This means they are accessed via the `Session`, rather than via TLS. A few `Attr` methods and `librustc_ast` functions are now methods of `Session`. All of this required passing a `Session` to lots of functions that didn't already have one. Some of these functions also had arguments removed, because those arguments could be accessed directly via the `Session` argument. `contains_feature_attr()` was dead, and is removed. Some functions were moved from `librustc_ast` elsewhere because they now need to access `Session`, which isn't available in that crate. - `entry_point_type()` --> `librustc_builtin_macros` - `global_allocator_spans()` --> `librustc_metadata` - `is_proc_macro_attr()` --> `Session`
2020-08-04rustc_ast: `(Nested)MetaItem::check_name` -> `has_name`Vadim Petrochenkov-1/+1
For consistency with `Attribute::has_name` which doesn't mark the attribute as used either. Replace all uses of `check_name` with `has_name` outside of rustc

2020-06-24Implement associated lang itemsAaron Hill-1/+4
Fixes #70718 This commit allows making associated items (e.g. associated functions and types) into lang items via the `#[lang]` attribute. This allows such items to be accessed directly, rather than by iterating over the parent item's associated items. I've added `FnOnce::Output` as a lang item, and updated one old usage to use the new lang item. The remaining uses can be updated separately.

2020-04-30Rollup merge of #71205 - NeoRaider:check_attr, r=jonas-schievinkDylan DPC-1/+4
rustc: fix check_attr() for methods, closures and foreign functions This fixes an issue that previously turned up for methods in https://github.com/rust-lang/rust/pull/69274, but also exists for closures and foreign function: `check_attr` does not call `codegen_fn_attrs()` for these types when it should, meaning that incorrectly used function attributes are not diagnosed without codegen. The issue affects our UI tests, as they run with `--emit=metadata` by default, but as it turns out, this is not the only case: Function attributes are not checked on any dead code without this fix! This makes the fix a **breaking change**. The following very silly Rust programs compiles fine on stable Rust when it should not, which is fixed by this PR. ```rust fn main() { #[target_feature(enable = "sse2")] || {}; } ``` I assume any real-world program which may trigger this issue would at least emit a dead code warning, but of course that is no guarantee that such code does not exist... Fixes #70307

2020-02-10Add `#[repr(no_niche)]`.Felix S. Klock II-3/+21
This repr-hint makes a struct/enum hide any niche within from its surrounding type-construction context. It is meant (at least initially) as an implementation detail for resolving issue 68303. We will not stabilize the repr-hint unless someone finds motivation for doing so. (So, declaration of `no_niche` feature lives in section of file where other internal implementation details are grouped, and deliberately leaves out the tracking issue number.) incorporated review feedback, and fixed post-rebase.
