2017-05-18Add an option to the parser to avoid parsing out of line modulesNick Cameron-2/+23
This is useful if parsing from stdin or a String and don't want to try and read in a module from another file. Instead we just leave a stub in the AST.

`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

2017-02-03Bump version, upgrade bootstrapAlex Crichton-2/+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.

Refactor the parser to consume token trees This is groundwork for efficiently parsing attribute proc macro invocations, bang macro invocations, and `TokenStream`-based attributes and fragment matchers. This improves parsing performance by 8-15% and expansion performance by 0-5% on a sampling of the compiler's crates. r? @nrc

2016-12-30Such large. Very 128. Much bits.Simonas Kazlauskas-2/+6
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-16/+16
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.

2016-09-16Overhaul char_lit().Nicholas Nethercote-43/+28
This commit does the following. - Removes parsing support for '\X12', '\u123456' and '\U12345678' char literals. These are no longer valid Rust and rejected by the lexer. (This strange-sounding situation occurs because the parser rescans char literals to compute their value.) - Rearranges the function so that all the escaped values are handled in a single `match`, and changes the error-handling to use vanilla assert!() and unwrap().
2016-09-12Lazily construct panic messages in char_lit().Nicholas Nethercote-5/+7
This reduces the time taken to run `rustc -Zparse-only rustc-benchmarks/issue-32278-big-array-of-strings` from 0.18s to 0.15s on my machine, and reduces the number of instructions (as measured by Cachegrind) from 1.34B to 1.01B. With the change applied, the time to fully compile that benchmark is 1.96s, so this is a 1.5% improvement.
2016-09-12Avoid an unnecessary intermediate value in char_lit().Nicholas Nethercote-14/+9
