2020-04-30Rollup merge of #71205 - NeoRaider:check_attr, r=jonas-schievinkDylan DPC-10/+55
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

non-exhastive diagnostic: add note re. scrutinee type This fixes https://github.com/rust-lang/rust/issues/67259 by adding a note: ``` = note: the matched value is of type &[i32] ``` to non-exhaustive pattern matching errors. r? @varkor @estebank

2020-03-26introduce `negative_impls` feature gate and documentNiko Matsakis-1/+1
They used to be covered by `optin_builtin_traits` but negative impls are now applicable to all traits, not just auto traits. This also adds docs in the unstable book for the current state of auto traits.

2020-03-23Ignore tests on some platforms due to #53081Aaron Hill-1/+6
2020-03-22Store idents for `DefPathData` into crate metadataAaron Hill-0/+5
Previously, we threw away the `Span` associated with a definition's identifier when we encoded crate metadata, causing us to lose location and hygiene information. We now store the identifier's `Span` in the crate metadata. When we decode items from the metadata, we combine the name and span back into an `Ident`. This improves the output of several tests, which previously had messages suppressed due to dummy spans. This is a prerequisite for #68686, since throwing away a `Span` means that we lose hygiene information.

Tweak output for invalid negative impl AST errors Use more accurate spans for negative `impl` errors. r? @Centril
2020-03-10Rollup merge of #69514 - GuillaumeGomez:remove-spotlight, r=kinnisonMazdak Farrokhzad-16/+0
Remove spotlight I had a few comments saying that this feature was at best misunderstood or not even used so I decided to organize a poll about on [twitter](https://twitter.com/imperioworld_/status/1232769353503956994). After 87 votes, the result is very clear: it's not useful. Considering the amount of code we have just to run it, I think it's definitely worth it to remove it. r? @kinnison cc @ollie27

Clean up unstable book - #58402's feature was renamed to `tidy_test_never_used_anywhere_else` and it is now used for tidy only - `read_initializer` link is wrong and the doc should be auto-generated so removed - Add dummy doc for `link_cfg` - Stop generating `compiler_builtins_lib` doc in favor of b8ccc0f8a60ac16fdc00f4b2e36e1a5db8b78295 - Make `rustc_attrs` tracking issue "None"

Address inconsistency in using "is" with "declared here" "is" was generally used for NLL diagnostics, but not other diagnostics. Using "is" makes the diagnostics sound more natural and readable, so it seems sensible to commit to them throughout. r? @Centril
