2021-12-18Re-introduce concept of projection cache 'completion'Aaron Hill-0/+1
Instead of clearing out the cache entirely, we store the intermediate evaluation result into the cache entry. This accomplishes several things: * We avoid the performance hit associated with re-evaluating the sub-obligations * We avoid causing issues with incremental compilation, since the final evaluation result is always the same * We avoid affecting other uses of the same `InferCtxt` which might care about 'side effects' from processing the sub-obligations (e,g. region constraints). Only code that is specifically aware of the new 'complete' code is affected

2021-10-16Adopt let_else across the compilerest31-0/+1
This performs a substitution of code following the pattern: let <id> = if let <pat> = ... { identity } else { ... : ! }; To simplify it to: let <pat> = ... { identity } else { ... : ! }; By adopting the let_else feature.

2021-05-13have on_completion record subcyclesNiko Matsakis-0/+1
Rework `on_completion` method so that it removes all provisional cache entries that are "below" a completed node (while leaving those entries that are not below the node). This corrects an imprecise result that could in turn lead to an incremental compilation failure. Under the old scheme, if you had: * A depends on... * B depends on A * C depends on... * D depends on C * T: 'static then the provisional results for A, B, C, and D would all be entangled. Thus, if A was `EvaluatedToOkModuloRegions` (because of that final condition), then the result for C and D would also be demoted to "ok modulo regions". In reality, though, the result for C depends only on C and itself, and is not dependent on regions. If we happen to evaluate the cycle starting from C, we would never reach A, and hence the result would be "ok". Under the new scheme, the provisional results for C and D are moved to the permanent cache immediately and are not affected by the result of A.

2021-03-06Change x64 size checks to not apply to x32.Harald van Dijk-1/+1
Rust contains various size checks conditional on target_arch = "x86_64", but these checks were never intended to apply to x86_64-unknown-linux-gnux32. Add target_pointer_width = "64" to the conditions.
2020-12-29Stabilize by-value `[T; N]` iterator `core::array::IntoIter`Simon Sapin-1/+0
Tracking issue: https://github.com/rust-lang/rust/issues/65798 This is unblocked now that `min_const_generics` has been stabilized in https://github.com/rust-lang/rust/pull/79135. This PR does *not* include the corresponding `IntoIterator` impl, which is https://github.com/rust-lang/rust/pull/65819. Instead, an iterator can be constructed through the `new` method. `new` would become unnecessary when `IntoIterator` is implemented and might be deprecated then, although it will stay stable.
