2019-07-22add rustc_private as a proper language feature gateAleksey Kladov-0/+1
At the moment, `rustc_private` as a (library) feature exists by accident: `char::is_xid_start`, `char::is_xid_continue` methods in libcore define it.
2019-07-20Auto merge of #62710 - estebank:bad-named-args, r=petrochenkovbors-15/+24
Specific error for positional args after named args in `format!()` When writing positional arguments after named arguments in the `format!()` and `println!()` macros, provide a targeted diagnostic. Follow up to https://github.com/rust-lang/rust/pull/57522/files#r247278885

2019-07-11hygiene: Introduce a helper method for creating new expansionsVadim Petrochenkov-4/+2
Creating a fresh expansion and immediately generating a span from it is the most common scenario. Also avoid allocating `allow_internal_unstable` lists for derive markers repeatedly. And rename `ExpnInfo::with_unstable` to `ExpnInfo::allow_unstable`, seems to be a better fitting name.
2019-07-11hygiene: Reuse `MacroKind` in `ExpnKind`Vadim Petrochenkov-2/+2
Orthogonality and reuse are good.
2019-07-11Remove unnecessary expansions created by `#[test_case/test/bench]`Vadim Petrochenkov-31/+21
The expansions were created to allow unstable things inside `#[test_case/test/bench]`, but that's not a proper way to do that. Put the required `allow_internal_unstable`s into the macros' properties instead.
2019-07-11Rename some things in `syntax_pos/hygiene`Vadim Petrochenkov-6/+6
More consistent with other naming: ExpnFormat -> ExpnKind ExpnKind::name -> ExpnKind::descr DesugaringKind::name -> DesugaringKind::descr Shorter, no tautology: CompilerDesugaring -> Desugaring CompilerDesugaringKind -> DesugaringKind

2019-07-07rustc: Remove `dylib` crate type from most rustc cratesAlex Crichton-1/+1
Now that procedural macros no longer link transitively to libsyntax, this shouldn't be needed any more! This commit is an experiment in removing all dynamic libraries from rustc except for librustc_driver itself. Let's see how far we can get with that!
2019-07-05Rollup merge of #61545 - flip1995:internal_lints, r=oli-obkMazdak Farrokhzad-1/+0
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

2019-06-23Fix meta-variable binding errors in macrosJulien Cretin-2/+2
The errors are either: - The meta-variable used in the right-hand side is not bound (or defined) in the left-hand side. - The meta-variable used in the right-hand side does not repeat with the same kleene operator as its binder in the left-hand side. Either it does not repeat enough, or it uses a different operator somewhere. This change should have no semantic impact.

2019-06-09Introduce InnerSpan abstractionMark Rousskov-20/+20
This should be used when trying to get at subsets of a larger span, especially when the larger span is not available in the code attempting to work with those subsets (especially common in the fmt_macros crate). This is usually a good replacement for (BytePos, BytePos) and (usize, usize) tuples. This commit also removes from_inner_byte_pos, since it took usize arguments, which is error prone.

parser: Remove `Deref` impl from `Parser` Follow up to https://github.com/rust-lang/rust/pull/61541 You have to write `self.token.span` instead of `self.span` in the parser now, which is not nice, but not too bad either, I guess. Not sure. Probably still better than people using both and being confused about the definition point of `span`. r? @oli-obk @estebank
