2019-10-18Change `Lit::tokens()` to `Lit::token_tree()`.Nicholas Nethercote-4/+5
Because most of the call sites have an easier time working with a `TokenTree` instead of a `TokenStream`.

2019-10-14Rollup merge of #65261 - nnethercote:rm-Option-from-TokenStream, r=petrochenkovTyler Mandry-1/+1
Remove `Option` from `TokenStream` A code simplification. r? @petrochenkov
2019-10-14Remove the `Option` in `TokenStream`.Nicholas Nethercote-1/+1
It means an allocation is required to create an empty `TokenStream`, but all other operations are simpler and marginally faster due to not having to check for `None`. Overall it simplifies the code for a negligible performance effect. The commit also removes `TokenStream::empty` by implementing `Default`, which is now possible.
2019-10-13ast: remove implicit pprust dependency via Display.Mazdak Farrokhzad-9/+25
Instead just use `pprust::path_to_string(..)` where needed. This has two benefits: a) The AST definition is now independent of printing it. (Therefore we get closer to extracting a data-crate.) b) Debugging should be easier as program flow is clearer.

2019-08-15`Ident::with_empty_ctxt` -> `Ident::with_dummy_span`Vadim Petrochenkov-2/+2
`Ident` has had a full span rather than just a `SyntaxContext` for a long time now.

2019-07-31Unify spanned and non-spanned Attribute ctorsMark Rousskov-14/+4
There is no difference in the code/arguments, so go with the shorter name throughout the code.
2019-07-25Rollup merge of #62735 - petrochenkov:galloc, r=alexcrichtonMazdak Farrokhzad-0/+97
Turn `#[global_allocator]` into a regular attribute macro It was a 99% macro with exception of some diagnostic details. As a result of the change, `#[global_allocator]` now works in nested modules and even in nameless blocks.

Implement another internal lints cc #49509 This adds ~~two~~ one internal lint~~s~~: 1. LINT_PASS_IMPL_WITHOUT_MACRO: Make sure, that the `{declare,impl}_lint_pass` macro is used to implement lint passes. cc #59669 2. ~~USAGE_OF_TYCTXT_AND_SPAN_ARGS: item 2 on the list in #49509~~ ~~With 2. I wasn't sure, if this lint should be applied everywhere. That means a careful review of 0955835 would be great. Also 73fb9b4 allows this lint on some functions. Should I also apply this lint there?~~ TODO (not directly relevant for review): - [ ] https://github.com/rust-lang/rust/pull/59316#discussion_r280186517 (not sure yet, if this works or how to query for `rustc_private`, since it's not in [`Features`](https://doc.rust-lang.org/nightly/nightly-rustc/syntax/feature_gate/struct.Features.html) :thinking: cc @eddyb) - [x] https://github.com/rust-lang/rust/pull/61735#discussion_r292389870 - [x] Check explicitly for the `{declare,impl}_lint_pass!` macros r? @oli-obk

Allow attributes in formal function parameters Implements https://github.com/rust-lang/rust/issues/60406. This is my first contribution to the compiler and since this is a large and complex project, I am not fully aware of the consequences of the changes I have made. **TODO** - [x] Forbid some built-in attributes. - [x] Expand cfg/cfg_attr
