2019-10-23Rollup merge of #65704 - RalfJung:exact-size, r=oli-obkMazdak Farrokhzad-2/+5
relax ExactSizeIterator bound on write_bytes Too many iterators don't have that bound. Instead we do run-time checks. r? @oli-obk

2019-10-23Rollup merge of #65657 - nnethercote:rm-InternedString-properly, r=eddybMazdak Farrokhzad-136/+146
Remove `InternedString` This PR removes `InternedString` by converting all occurrences to `Symbol`. There are a handful of places that need to use the symbol chars instead of the symbol index, e.g. for stable sorting; local conversions `LocalInternedString` is used in those places. r? @eddyb
2019-10-23Rollup merge of #65193 - Mark-Simulacrum:lockless-lintstore, r=nikomatsakisMazdak Farrokhzad-238/+303
Lockless LintStore This removes mutability from the lint store after registration. Each commit stands alone, for the most part, though they don't make sense out of sequence. The intent here is to move LintStore to a more parallel-friendly architecture, although also just a cleaner one from an implementation perspective. Specifically, this has the following changes: * We no longer implicitly register lints when registering lint passes * For the most part this means that registration calls now likely want to call something like: `lint_store.register_lints(&Pass::get_lints())` as well as `register_*_pass`. * In theory this is a simplification as it's much easier for folks to just register lints and then have passes that implement whichever lint however they want, rather than necessarily tying passes to lints. * Lint passes still have a list of associated lints, but a followup PR could plausibly change that * This list must be known for a given pass type, not instance, i.e., `fn get_lints()` is the signature instead of `fn get_lints(&self)` as before. * We do not store pass objects, instead storing constructor functions. This means we always get new passes when running lints (this happens approximately once though for a given compiler session, so no behavior change is expected). * Registration API is _much_ simpler: generally all functions are just taking `Fn() -> PassObject` rather than several different `bool`s.

This is so we avoid a massive break of other people's code. Gonna run rustfmt and split the file on a different PR.

This prepares the code base for when projection is interned. Place's projection field is going to be `&List<PlaceElem<'tcx>>` so we won't be able to pattern match against it.

Rename `ConstValue::Infer(InferConst::Canonical(..))` to `ConstValue::Bound(..)` It already has the right form, so this is just a renaming. Fixes https://github.com/rust-lang/rust/issues/65655. r? @eddyb

miri: add write_bytes method to Memory doing bounds-checks and supporting iterators This lets us avoid some direct `Allocation` accesses in Miri.
2019-10-21Rollup merge of #62330 - SimonSapin:no-drop-in-union-fields, r=RalfJungMazdak Farrokhzad-1/+3
Change untagged_unions to not allow union fields with drop This is a rebase of #56440, massaged to solve merge conflicts and make the test suite pass. Change untagged_unions to not allow union fields with drop Union fields may now never have a type with attached destructor. This for example allows unions to use arbitrary field types only by wrapping them in `ManuallyDrop` (or similar). The stable rule remains, that union fields must be `Copy`. We use the new rule for the `untagged_union` feature. Tracking issue: https://github.com/rust-lang/rust/issues/55149

2019-10-21Use `Symbol` for codegen unit names.Nicholas Nethercote-17/+16
This is a straightforward replacement except for two places where we have to convert to `LocalInternedString` to get a stable sort.
2019-10-21Change `SymbolName::name` from `InternedString` to `Symbol`.Nicholas Nethercote-8/+21
This requires changing the `PartialOrd`/`Ord` implementations to look at the chars rather than the symbol index.
