* Merge #5149bors[bot]2020-07-011-13/+30
|\ | | | | | | | | | | | | | | | | | | 5149: Implement Chalk variable kinds r=flodiebold a=flodiebold This means we need to keep track of the kinds (general/int/float) of variables in `Canonical`, which requires some more ceremony. (It also exposes some places where we're not really dealing with canonicalization correctly -- another thing to be cleaned up when we switch to using Chalk's types directly.) Should fix the last remaining issue of #2534. Co-authored-by: Florian Diebold <[email protected]>

* | Split `CrateImplDefs` in inherent and trait implsJonas Schievink2020-07-011-6/+4
|/ | | | | | This makes the intention of inherent vs. trait impls somewhat more clear and also fixes (?) an issue where trait impls with an unresolved trait were added as inherent impls instead (hence the test changes).

Remove it, instead adding a query that computes a summary `CrateImplDefs` map for all transitive dependencies. This can probably still be made more efficient, but this already reduces the peak memory usage by 25% without much performance impact on analysis-stats. **Before**: ``` Total: 34.962107188s, 2083mb allocated 2141mb resident 422mb ImplsForTraitQuery (deps) 250mb CrateDefMapQueryQuery 147mb MacroArgQuery 140mb TraitSolveQuery (deps) 68mb InferQueryQuery (deps) 62mb ImplDatumQuery (deps) ``` **After**: ``` Total: 35.261100358s, 1520mb allocated 1569mb resident 250mb CrateDefMapQueryQuery 147mb MacroArgQuery 144mb TraitSolveQuery (deps) 68mb InferQueryQuery (deps) 61mb ImplDatumQuery (deps) 45mb BodyQuery 45mb ImplDatumQuery ``` Co-authored-by: Jonas Schievink <[email protected]>

* Clean up handling of int/float literal typesFlorian Diebold2020-06-061-13/+11
| | | | | | 'Unknown' int/float types actually never exist as such, they get replaced by type variables immediately. So the whole `Uncertain<IntTy>` thing was unnecessary and just led to a bunch of match branches that were never hit.

* | Implement return position impl trait / opaque type supportFlorian Diebold2020-06-054-15/+89
|/ | | | | | | | | | | | | This is working, but I'm not that happy with how the lowering works. We might need an additional representation between `TypeRef` and `Ty` where names are resolved and `impl Trait` bounds are separated out, but things like inference variables don't exist and `impl Trait` is always represented the same way. Also note that this doesn't implement correct handling of RPIT *inside* the function (which involves turning the `impl Trait`s into variables and creating obligations for them). That intermediate representation might help there as well.
* Upgrade ChalkFlorian Diebold2020-05-273-52/+52
| | | | | Chalk newly added TypeName::Never and Array; I implemented the conversion for Never, but not Array since that expects a const argument.
* Fix some clippy perf warningsJeremy Kolb2020-05-251-2/+1

* Use Chalk's Ty::Function for function pointer typesFlorian Diebold2020-05-221-8/+19
| | | | | | Function pointers can be 'higher-ranked' over lifetimes, which is why they're not an application type in Chalk, but since we don't model lifetimes it doesn't matter for us yet.

| | | | | As always, this just makes compilation work, we don't use the newly available functionality yet.

* Update Chalk, and cache Chalk env elaboration through a queryFlorian Diebold2020-04-202-25/+153
| | | | This should fix some of the worst performance problems.
* Fix another crash from wrong bindersFlorian Diebold2020-04-171-5/+5
| | | | | | | Basically, if we had something like `dyn Trait<T>` (where `T` is a type parameter) in an impl we lowered that to `dyn Trait<^0.0>`, when it should be `dyn Trait<^1.0>` because the `dyn` introduces a new binder. With one type parameter, that's just wrong, with two, it'll lead to crashes.

This is an unstable feature, but it's used in the standard library e.g. in the definition of Flatten, so we can't get away with not implementing it :) (This is cherry-picked from my recursive solver branch, where it works better, but I did manage to write a test that works with the current Chalk solver as well...) 3967: Handle `Self::Type` in trait definitions when referring to own associated type r=matklad a=flodiebold It was implemented for other generic parameters for the trait, but not for `Self`.

* Implement Chalk's debug methods using TLSFlorian Diebold2020-04-102-42/+270
| | | | | | | | | | Chalk now panics if we don't implement these methods and run with CHALK_DEBUG, so I thought I'd try to implement them 'properly'. Sadly, it seems impossible to do without transmuting lifetimes somewhere. The problem is that we need a `&dyn HirDatabase` to get names etc., which we can't just put into TLS. I thought I could just use `scoped-tls`, but that doesn't support references to unsized types. So I put the `&dyn` into another struct and put the reference to *that* into the TLS, but I have to transmute the lifetime to 'static for that to work.
* Fix Chalk panicFlorian Diebold2020-04-061-1/+6
| | | | | Fixes #3865. Basically I forgot to shift 'back' when we got `dyn Trait`s back from Chalk, so after going through Chalk a few times, the panic happened.
* Upgrade Chalk againFlorian Diebold2020-04-052-30/+53
| | | | | | | The big change here is counting binders, not variables (https://github.com/rust-lang/chalk/pull/360). We have to adapt to the same scheme for our `Ty::Bound`. It's mostly fine though, even makes some things more clear.

| | | | | | | It improves compile time in `--release` mode quite a bit, it doesn't really slow things down and, conceptually, it seems closer to what we want the physical architecture to look like (we don't want to monomorphise EVERYTHING in a single leaf crate).
