2021-07-23Auto merge of #86429 - JohnTitor:get-by-key-enum-part-2, r=oli-obkbors-49/+23
Improve `get_by_key_enumerated` more Follow-up of #86392, this applies the suggestions by `@m-ou-se.` r? `@m-ou-se`
2021-07-23Add VecMap::get_value_matching and assert if > 1 elementSantiago Pastorino-4/+23
Otherwise is a bug that we want to uncover.

2021-07-23Auto merge of #87287 - oli-obk:fixup_fixup_fixup_opaque_types, r=spastorinobors-5/+10
Make mir borrowck's use of opaque types independent of the typeck query's result fixes #87218 fixes #86465 we used to use the typeck results only to generate an obligation for the mir borrowck type to be equal to the typeck result. When i removed the `fixup_opaque_types` function in #87200, I exposed a bug that showed that mir borrowck can't doesn't get enough information from typeck in order to build the correct lifetime mapping from opaque type usage to the actual concrete type. We therefor now fully compute the information within mir borrowck (we already did that, but we only used it to verify the typeck result) and stop using the typeck information. We will likely be able to remove most opaque type information from the borrowck results in the future and just have all current callers use the mir borrowck result instead. r? `@spastorino`

2021-07-22Fix VecMap::iter_mutOli Scherer-5/+6
It used to allow you to mutate the key, even though that can invalidate the map by creating duplicate keys.
2021-07-22Auto merge of #86619 - rylev:incr-hashing-profiling, r=wesleywiserbors-11/+49
Profile incremental compilation hashing fingerprints Adds profiling instrumentation for the hashing of incremental compilation fingerprints per query. This will eventually feed into the `measureme` and `rustc-perf` infrastructure for tracking if computing hashes changes over time. TODOs: * [x] Address the FIXME where we are including node interning in the hash timing. * [ ] Update measureme/summarize to handle this new data: https://github.com/rust-lang/measureme/pull/166 * [ ] ~Update rustc-perf to handle the new data from measureme~ (will be done at a later time) r? `@ghost` cc `@michaelwoerister`

Remove `#[allow(unused_lifetimes)]` which is now unnecessary Seems FP has been fixed, it doesn't need `#[allow(unused_lifetimes)]` anymore.

2021-06-11Auto merge of #85885 - bjorn3:remove_box_region, r=cjgillotbors-171/+0
Don't use a generator for BoxedResolver The generator is non-trivial and requires unsafe code anyway. Using regular unsafe code without a generator is much easier to follow. Based on #85810 as it touches rustc_interface too.

Avoid cloning cache key r? `@estebank`
2021-06-04Unify parallel and non-parallel APIsJoshua Nelson-2/+54
It's confusing for these to be different, even if some of the methods are unused.

2021-06-04Rollup merge of #85850 - bjorn3:less_feature_gates, r=jyn514Yuki Okushi-21/+1
Remove unused feature gates The first commit removes a usage of a feature gate, but I don't expect it to be controversial as the feature gate was only used to workaround a limitation of rust in the past. (closures never being `Clone`) The second commit uses `#[allow_internal_unstable]` to avoid leaking the `trusted_step` feature gate usage from inside the index newtype macro. It didn't work for the `min_specialization` feature gate though. The third commit removes (almost) all feature gates from the compiler that weren't used anyway.

2021-04-21Use arrayvec 0.7, drop smallvec 0.6Jubilee Young-8/+5
With the arrival of min const generics, many alt-vec libraries have updated to use it in some way and arrayvec is no exception. Use the latest with minor refactoring. Also, rustc_workspace_hack is the only user of smallvec 0.6 in the entire tree, so drop it.
2021-04-08Fix outdated crate names in compiler docspierwill-1/+1
Changes `librustc_X` to `rustc_X`, only in documentation comments. Plain code comments are left unchanged. Also fix incorrect file paths.
2021-04-06Auto merge of #83821 - camelid:improve-thinvec, r=petrochenkovbors-0/+91
Add `FromIterator` and `IntoIterator` impls for `ThinVec` These should make using `ThinVec` feel much more like using `Vec`. They will allow users of `Vec` to switch to `ThinVec` while continuing to use `collect()`, `for` loops, and other parts of the iterator API. I don't know if there were use cases before for using the iterator API with `ThinVec`, but I would like to start using `ThinVec` in rustdoc, and having it conform to the iterator API would make the transition *a lot* easier. I added a `FromIterator` impl, an `IntoIterator` impl that yields owned elements, and `IntoIterator` impls that yield immutable or mutable references to elements. I also added some unit tests for `ThinVec`.

2021-04-03Auto merge of #83682 - bjorn3:mmap_wrapper, r=cjgillotbors-0/+48
Add an Mmap wrapper to rustc_data_structures This wrapper implements StableAddress and falls back to directly reading the file on wasm32. Taken from #83640, which I will close due to the perf regression.

2021-03-29Revert changes to sync data structuresJoshua Nelson-0/+110
There isn't currently a good reviewer for these, and I don't want to remove things that will just be added again. I plan to make a separate PR for these changes so the rest of the cleanup can land.
2021-03-27Address review commentsJoshua Nelson-2/+0
- Add back `HirIdVec`, with a comment that it will soon be used. - Add back `*_region` functions, with a comment they may soon be used. - Remove `-Z borrowck_stats` completely. It didn't do anything. - Remove `make_nop` completely. - Add back `current_loc`, which is used by an out-of-tree tool. - Fix style nits - Remove `AtomicCell` with `cfg(parallel_compiler)` for consistency.
