2018-12-12Rename `TokenStream::concat` and remove `TokenStream::concat_rc_vec`.Nicholas Nethercote-1/+1
`TokenStream::new` is a better name for the former, and the latter is now just equivalent to `TokenStream::Stream`.
2018-12-10Remove `tokenstream::Delimited`.Nicholas Nethercote-17/+15
Because it's an extra type layer that doesn't really help; in a couple of places it actively gets in the way, and overall removing it makes the code nicer. It does, however, move `tokenstream::TokenTree` further away from the `TokenTree` in `quote.rs`. More importantly, this change reduces the size of `TokenStream` from 48 bytes to 40 bytes on x86-64, which is enough to slightly reduce instruction counts on numerous benchmarks, the best by 1.5%. Note that `open_tt` and `close_tt` have gone from being methods on `Delimited` to associated methods of `TokenTree`.

2018-12-02Remove not used `DotEq` tokenyui-knk-1/+0
Currently libproc_macro does not use `DotEq` token. https://github.com/rust-lang/rust/pull/49545 changed libproc_macro to not generate `DotEq` token.
2018-11-08Rollup merge of #55777 - nnethercote:less-P-in-ast, r=petrochenkovMark Rousskov-2/+2
Use `Lit` rather than `P<Lit>` in `ast::ExprKind`. Because it results in fewer allocations and small speedups on some benchmarks.

This reduces the size of `Token` from 32 bytes to 24 bytes on 64-bit platforms.

2017-12-28Resurrecting #33135Michael Hewson-0/+7
Started rebasing @sgrif's PR #33135 off of current master. (Well, actually merging it into a new branch based off current master.) The following files still need to be fixed or at least reviewed: - `src/libsyntax/ext/tt/macro_parser.rs`: calls `Parser::parse_lifetime`, which doesn't exist anymore - `src/libsyntax/parse/parser.rs`: @sgrif added an error message to `Parser::parse_lifetime`. Code has since been refactored, so I just took it out for now. - `src/libsyntax/ext/tt/transcribe.rs`: This code has been refactored bigtime. Not sure whether @sgrif's changes here are still necessary. Took it out for this commit.

Fix #35829 (`quote!()` does not handle `br#"…"#`) Fix issue #35829 (syntax extension's `quote_expr!()` does not handle `b"…"` and proc_macro's `quote!()` does not handle `r#"…"#`) * Handles `b"…"`, `br#"…"#` and `...` for `quote_expr!()`. * Refactored the match statement to allow it to complain loudly on any unhandled token. * Similarly, proc_macro's `quote!()` did not handle `br#"…"#` or `r#"…"#`, so this PR fixes it too.

This commit updates the version number to 1.17.0 as we're not on that version of the nightly compiler, and at the same time this updates src/stage0.txt to bootstrap from freshly minted beta compiler and beta Cargo.

2016-12-30Such large. Very 128. Much bits.Simonas Kazlauskas-2/+4
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.
