* Introduce `GenericArg` like in ChalkFlorian Diebold2021-04-035-46/+58
| | | | | | | Plus some more adaptations to Substitution. Lots of `assert_ty_ref` that we should revisit when introducing lifetime/const parameters.
* Don't recheck obligations if we have learned nothing newFlorian Diebold2021-04-013-5/+11
| | | | | | | | | | This is just the most trivial check: If no inference variables have been updated, and there are no new obligations, we can just skip trying to solve them again. We could be smarter about it, but this already helps quite a bit, and I don't want to touch this too much before we replace the inference table by Chalk's. Fixes #8263 (well, improves it quite a bit).
* internal: ensure that runaway type-inference doesn't block the main loopAleksey Kladov2021-03-291-0/+2
| | | | | | We have a bug where type-checking `per_query_memory_usage` takes a couple of seconds. It also reveals another bug: our type inference is not cancellable.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 8201: Fix recursive macro statements expansion r=edwin0cheng a=edwin0cheng This PR attempts to properly handle macro statement expansion by implementing the following: 1. Merge macro expanded statements to parent scope statements. 2. Add a new hir `Expr::MacroStmts` for handle tail expression infer. PS : The scope of macro expanded statements are so strange that it took more time than I thought to understand and implement it :( Fixes #8171 Co-authored-by: Edwin Cheng <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 7907: Autoderef with visibility r=cynecx a=cynecx Fixes https://github.com/rust-analyzer/rust-analyzer/issues/7841. I am not sure about the general approach here. Right now this simply tries to check whether the autoderef candidate is reachable from the current module. ~~However this doesn't exactly work with traits (see the `tests::macros::infer_derive_clone_in_core` test, which fails right now).~~ see comment below Refs: - `rustc_typeck` checking fields: https://github.com/rust-lang/rust/blob/66ec64ccf31883cd2c28d045912a76179c0c6ed2/compiler/rustc_typeck/src/check/expr.rs#L1610 r? @flodiebold Co-authored-by: cynecx <[email protected]>

|\ \ | | | | | | | | | | | | | | | | | | | | | 8139: Align `Canonical` and `InEnvironment` with the Chalk versions r=flodiebold a=flodiebold Co-authored-by: Florian Diebold <[email protected]>
| * | Align InEnvironment with ChalkFlorian Diebold2021-03-213-16/+13
| | | | | | | | | | | | | | | | | | This in particular means storing a chalk_ir::Environment, not our TraitEnvironment. This makes InEnvironment not usable for Type, where we need to keep the full TraitEnvironment.
| * | Align Canonical more with Chalk's versionFlorian Diebold2021-03-211-14/+30

There's a lot of skipping of the binders; once we're done with the Chalk move, we should review the remaining ones. 8146: Document patch policy r=matklad a=matklad bors r+ 🤖 Co-authored-by: Florian Diebold <[email protected]> Co-authored-by: Aleksey Kladov <[email protected]>

| | | | | | | | | | | | | | | Still far too much binder skipping going on; I find it hard to imagine this is all correct, but the tests pass.

|\ | | | | | | | | | | | | | | | | | | 8018: Make Ty wrap TyKind in an Arc r=flodiebold a=flodiebold ... to further move towards Chalk. This is a bit of a slowdown (218ginstr vs 213ginstr for inference on RA), even though it allows us to unwrap the Substs in `TyKind::Ref` etc.. Co-authored-by: Florian Diebold <[email protected]>

| | | | | | | | | | | | | | | | ... like it will be in Chalk. We still keep `interned_mut` and `into_inner` methods that will probably not exist with Chalk. This worsens performance slightly (5ginstr inference on RA), but doesn't include other simplifications we can do yet.
