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.

2017-05-17Auto merge of #41961 - kennytm:fix-35829, r=petrochenkovbors-36/+20
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 is mostly removing stray ampersands, needless returns and lifetimes.

2017-02-03Bump version, upgrade bootstrapAlex Crichton-1/+0
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.

2016-10-31Changed most vec! invocations to use square bracesiirelu-31/+31
Most of the Rust community agrees that the vec! macro is clearer when called using square brackets [] instead of regular brackets (). Most of these ocurrences are from before macros allowed using different types of brackets. There is one left unchanged in a pretty-print test, as the pretty printer still wants it to have regular brackets.
2016-10-29Move `CrateConfig` from `Crate` to `ParseSess`.Jeffrey Seyfried-13/+1
2016-10-14Avoid many CrateConfig clones.Nicholas Nethercote-5/+9
This commit changes `ExtCtx::cfg()` so it returns a `CrateConfig` reference instead of a clone. As a result, it also changes all of the `cfg()` callsites to explicitly clone... except one, because the commit also changes `macro_parser::parse()` to take `&CrateConfig`. This is good, because that function can be hot, and `CrateConfig` is expensive to clone. This change almost halves the number of heap allocations done by rustc for `html5ever` in rustc-benchmarks suite, which makes compilation 1.20x faster.

2016-06-26Rollup merge of #34436 - jseyfried:no_block_expr, r=eddybJeffrey Seyfried-13/+11
To allow these braced macro invocation, this PR removes the optional expression from `ast::Block` and instead uses a `StmtKind::Expr` at the end of the statement list. Currently, braced macro invocations in blocks can expand into statements (and items) except when they are last in a block, in which case they can only expand into expressions. For example, ```rust macro_rules! make_stmt { () => { let x = 0; } } fn f() { make_stmt! {} //< This is OK... let x = 0; //< ... unless this line is commented out. } ``` Fixes #34418.

syntax-[breaking-change] cc #31645 (Only breaking because ast::TokenTree is now tokenstream::TokenTree.) This pull request refactors TokenTrees into their own file as src/libsyntax/tokenstream.rs, moving them out of src/libsyntax/ast.rs, in order to prepare for an accompanying TokenStream implementation (per RFC 1566).
