Add Span to ast::WhereClause This PR adds `Span` field to `ast::WhereClause`. The motivation here is to make rustfmt's life easier when recovering comments before and after where clause. r? @nrc

2017-07-28syntax: Capture a `TokenStream` when parsing itemsAlex Crichton-0/+7
This is then later used by `proc_macro` to generate a new `proc_macro::TokenTree` which preserves span information. Unfortunately this isn't a bullet-proof approach as it doesn't handle the case when there's still other attributes on the item, especially inner attributes. Despite this the intention here is to solve the primary use case for procedural attributes, attached to functions as outer attributes, likely bare. In this situation we should be able to now yield a lossless stream of tokens to preserve span information.

2017-07-28syntax: Add `tokens: Option<TokenStream>` to ItemAlex Crichton-0/+6
This commit adds a new field to the `Item` AST node in libsyntax to optionally contain the original token stream that the item itself was parsed from. This is currently `None` everywhere but is intended for use later with procedural macros.

Replaced by adding extra imports, adding hidden code (`# ...`), modifying examples to be runnable (sorry Homura), specifying non-Rust code, and converting to should_panic, no_run, or compile_fail. Remaining "```ignore"s received an explanation why they are being ignored.

2017-04-24support `default impl` for specializationGianni Ciccarelli-0/+1
this commit implements the first step of the `default impl` feature: all items in a `default impl` are (implicitly) `default` and hence specializable. In order to test this feature I've copied all the tests provided for the `default` method implementation (in run-pass/specialization and compile-fail/specialization directories) and moved the `default` keyword from the item to the impl. See referenced issue for further info

2017-04-02Introduce `TyErr` independent from `TyInfer`Esteban Küber-0/+2
Add a `TyErr` type to represent unknown types in places where parse errors have happened, while still able to build the AST. Initially only used to represent incorrectly written fn arguments and avoid "expected X parameters, found Y" errors when called with the appropriate amount of parameters. We cannot use `TyInfer` for this as `_` is not allowed as a valid argument type. Example output: ```rust error: expected one of `:` or `@`, found `,` --> file.rs:12:9 | 12 | fn bar(x, y: usize) {} | ^ error[E0061]: this function takes 2 parameters but 3 parameters were supplied --> file.rs:19:9 | 12 | fn bar(x, y) {} | --------------- defined here ... 19 | bar(1, 2, 3); | ^^^^^^^ expected 2 parameters ```

`TokenStream`-based attributes, paths in attribute and derive macro invocations This PR - refactors `Attribute` to use `Path` and `TokenStream` instead of `MetaItem`. - supports macro invocation paths for attribute procedural macros. - e.g. `#[::foo::attr_macro] struct S;`, `#[cfg_attr(all(), foo::attr_macro)] struct S;` - supports macro invocation paths for derive procedural macros. - e.g. `#[derive(foo::Bar, super::Baz)] struct S;` - supports arbitrary tokens as arguments to attribute procedural macros. - e.g. `#[foo::attr_macro arbitrary + tokens] struct S;` - supports using arbitrary tokens in "inert attributes" with derive procedural macros. - e.g. `#[derive(Foo)] struct S(#[inert arbitrary + tokens] i32);` where `#[proc_macro_derive(Foo, attributes(inert))]` r? @nrc

2017-03-12Rollup merge of #40369 - petrochenkov:segspan, r=eddybCorey Farwell-7/+7
Give spans to individual path segments in AST And use these spans in path resolution diagnostics. The spans are spans of identifiers in segments, not whole segments. I'm not sure what spans are more useful in general, but identifier spans are a better fit for resolve errors. HIR still doesn't have spans.

2017-01-17Auto merge of #39110 - petrochenkov:sum, r=eddybbors-12/+12
Merge ObjectSum and PolyTraitRef in AST/HIR + some other refactoring `ObjectSum` and `PolyTraitRef` are the same thing (list of bounds), they exist separately only due to parser quirks. The second commit merges them. The first commit replaces `Path` with `Ty` in (not yet supported) equality predicates. They are parsed as types anyway and arbitrary types can always be disguised as paths using aliases, so this doesn't add any new functionality. The third commit uses `Vec` instead of `P<[T]>` in AST. AST is not immutable like HIR and `Vec`s are more convenient for it, unnecessary conversions are also avoided. The last commit renames `parse_ty_sum` (which is used for parsing types in general) into `parse_ty`, and renames `parse_ty` (which is used restricted contexts where `+` is not permitted due to operator priorities or other reasons) into `parse_ty_no_plus`. This is the first part of https://github.com/rust-lang/rust/issues/39085#issuecomment-272743755 and https://github.com/rust-lang/rust/issues/39080 focused on data changes and mechanical renaming, I'll submit a PR with parser changes a bit later. r? @eddyb

2016-12-30Such large. Very 128. Much bits.Simonas Kazlauskas-8/+20
This commit introduces 128-bit integers. Stage 2 builds and produces a working compiler which understands and supports 128-bit integers throughout. The general strategy used is to have rustc_i128 module which provides aliases for iu128, equal to iu64 in stage9 and iu128 later. Since nowhere in rustc we rely on large numbers being supported, this strategy is good enough to get past the first bootstrap stages to end up with a fully working 128-bit capable compiler. In order for this strategy to work, number of locations had to be changed to use associated max_value/min_value instead of MAX/MIN constants as well as the min_value (or was it max_value?) had to be changed to use xor instead of shift so both 64-bit and 128-bit based consteval works (former not necessarily producing the right results in stage1). This commit includes manual merge conflict resolution changes from a rebase by @est31.
