2017-04-12Rollup merge of #41063 - nikomatsakis:issue-40746-always-exec-loops, r=eddybTim Neumann-0/+21
remove unnecessary tasks Remove various unnecessary tasks. All of these are "always execute" tasks that don't do any writes to tracked state (or else an assert would trigger, anyhow). In some cases, they issue lints or errors, but we''ll deal with that -- and anyway side-effects outside of a task don't cause problems for anything that I can see. The one non-trivial refactoring here is the borrowck conversion, which adds the requirement to go from a `DefId` to a `BodyId`. I tried to make a useful helper here. r? @eddyb cc #40746 cc @cramertj @michaelwoerister
2017-04-07ICH: Centrally compute and cache DefPath hashes as part of DefPathTable.Michael Woerister-37/+97
2017-04-06Introduce HashStable trait and base ICH implementations on it.Michael Woerister-0/+4
This initial commit provides implementations for HIR, MIR, and everything that also needs to be supported for those two.

2017-03-23Remove internal liblogAlex Crichton-1/+1
This commit deletes the internal liblog in favor of the implementation that lives on crates.io. Similarly it's also setting a convention for adding crates to the compiler. The main restriction right now is that we want compiler implementation details to be unreachable from normal Rust code (e.g. requires a feature), and by default everything in the sysroot is reachable via `extern crate`. The proposal here is to require that crates pulled in have these lines in their `src/lib.rs`: #![cfg_attr(rustbuild, feature(staged_api, rustc_private))] #![cfg_attr(rustbuild, unstable(feature = "rustc_private", issue = "27812"))] This'll mean that by default they're not using these attributes but when compiled as part of the compiler they do a few things: * Mark themselves as entirely unstable via the `staged_api` feature and the `#![unstable]` attribute. * Allow usage of other unstable crates via `feature(rustc_private)` which is required if the crate relies on any other crates to compile (other than std).
2017-03-22Allocate numerical values of DefIndexes from two seperate ranges.Michael Woerister-52/+128
This way we can have all item-likes occupy a dense range of DefIndexes, which is good for making fast, array-based dictionaries.
2017-03-22Introduce HirId, a replacement for NodeId after lowering to HIR.Michael Woerister-2/+221
HirId has a more stable representation than NodeId, meaning that modifications to one item don't influence (part of) the IDs within other items. The other part is a DefIndex for which there already is a way of stable hashing and persistence. This commit introduces the HirId type and generates a HirId for every NodeId during HIR lowering, but the resulting values are not yet used anywhere, except in consistency checks.

2017-01-26Point to immutable arg/fields when trying to use as &mutEsteban Küber-1/+1
Point to immutable borrow arguments and fields when trying to use them as mutable borrows. Add label to primary span on "cannot borrow as mutable" errors. Present the following output when trying to access an immutable borrow's field as mutable: ``` error[E0389]: cannot borrow data mutably in a `&` reference --> $DIR/issue-38147-1.rs:27:9 | 26 | fn f(&self) { | ----- use `&mut self` here to make mutable 27 | f.s.push('x'); | ^^^ assignment into an immutable reference ``` And the following when trying to access an immutable struct field as mutable: ``` error: cannot borrow immutable borrowed content `*self.s` as mutable --> $DIR/issue-38147-3.rs:17:9 | 12 | s: &'a String | ------------- use `&'a mut String` here to make mutable ...| 16 | fn f(&self) { | ----- use `&mut self` here to make mutable 17 | self.s.push('x'); | ^^^^^^ cannot borrow as mutable ```

2016-12-15Use StableHasher everywhereAriel Ben-Yehuda-3/+3
The standard implementations of Hasher have architecture-dependent results when hashing integers. This causes problems when the hashes are stored within metadata - metadata written by one host architecture can't be read by another. To fix that, implement an architecture-independent StableHasher and use it in all places an architecture-independent hasher is needed. Fixes #38177.
