2014-02-24Transition to new `Hash`, removing IterBytes and std::to_bytes.Huon Wilson-4/+4
2014-02-23Make break and continue hygienicEdward Wang-2/+2
Makes labelled loops hygiene by performing renaming of the labels defined in e.g. `'x: loop { ... }` and then used in break and continue statements within loop body so that they act hygienically when used with macros. Closes #12262.
2014-02-14Refactored ast_map and friends, mainly to have Paths without storing them.Eduard Burtescu-118/+103
2014-02-13Replace `extern mod` with `extern crate`Flavio Percoco-26/+27
This patch adds a new keyword `crate` which is intended to replace mod in the context of `extern mod` as part of the issue #9880. The patch doesn't replace all `extern mod` cases since it is necessary to first push a new snapshot 0. The implementation could've been less invasive than this. However I preferred to take this chance to split the `parse_item_foreign_mod` method and pull the `extern crate` part out of there, hence the new method `parse_item_foreign_crate`.
2014-02-11Reserve `do` as a keywordEduard Bopp-0/+1
Resolves issue #12157. `do` is hereby reinstated as a keyword; no syntax is associated with it though. Along the way, a unit test had to be adapted, since it was using `do` as a method identifier. Breaking changes: - Any code using `do` as an identifier will no longer work.
2014-02-08std::fmt: convert the formatting traits to a proper self.Huon Wilson-2/+2
Poly and String have polymorphic `impl`s and so require different method names.
2014-02-05pull extra::{serialize, ebml} into a separate libserialize crateJeff Olson-1/+1
- `extra::json` didn't make the cut, because of `extra::json` required dep on `extra::TreeMap`. If/when `extra::TreeMap` moves out of `extra`, then `extra::json` could move into `serialize` - `libextra`, `libsyntax` and `librustc` depend on the newly created `libserialize` - The extensions to various `extra` types like `DList`, `RingBuf`, `TreeMap` and `TreeSet` for `Encodable`/`Decodable` were moved into the respective modules in `extra` - There is some trickery, evident in `src/libextra/lib.rs` where a stub of `extra::serialize` is set up (in `src/libextra/serialize.rs`) for use in the stage0 build, where the snapshot rustc is still making deriving for `Encodable` and `Decodable` point at extra. Big props to @huonw for help working out the re-export solution for this extra: inline extra::serialize stub fix stuff clobbered in rebase + don't reexport serialize::serialize no more globs in libserialize syntax: fix import of libserialize traits librustc: fix bad imports in encoder/decoder add serialize dep to librustdoc fix failing run-pass tests w/ serialize dep adjust uuid dep more rebase de-clobbering for libserialize fixing tests, pushing libextra dep into cfg(test) fix doc code in extra::json adjust index.md links to serialize and uuid library

2014-01-29Removing support for the do syntax from libsyntax and librustc.Scott Lawrence-40/+39
Fixes #10815.

2013-12-11Separate strict/reserved keywords, derive bounds.Chris Morgan-11/+29
It's twenty lines longer, but makes for clearer separation of strict and reserved keywords (probably a good thing) and removes another moving part (the definitions of `(STRICT|RESERVED)_KEYWORD_(START|FINAL)`).
2013-12-11Remove the following unused special identifiers:Chris Morgan-107/+67
- underscore ("_") - unary ("unary") - not_fn ("!") - idx_fn ("[]") - unary_minus_fn ("unary-") - item ("item") - block ("block") - stmt ("stmt") - pat ("pat") - expr ("expr") - ty ("ty") - ident ("ident") - path ("path") - descrim ("descrim") - clownshoe_stack_shim ("__rust_stack_shim") - blk ("blk") - c_abi ("C") (And, of course, renumber everything to match.)
2013-12-11Deduplicate in syntax::parse::token with a macro.Chris Morgan-271/+183
I also renumbered things at the same time; ``in`` was shifted into its alphabetical position and the reserved keywords were reordered (a couple of them were out of order).

2013-11-26auto merge of #10670 : eddyb/rust/node-u32, r=alexcrichtonbors-6/+6
### Rationale There is no reason to support more than 2³² nodes or names at this moment, as compiling something that big (even without considering the quadratic space usage of some analysis passes) would take at least **64GB**. Meanwhile, some can't (or barely can) compile rustc because it requires almost **1.5GB**. ### Potential problems Can someone confirm this doesn't affect metadata (de)serialization? I can't tell myself, I know nothing about it. ### Results Some structures have a size reduction of 25% to 50%: [before](https://gist.github.com/luqmana/3a82a51fa9c86d9191fa) - [after](https://gist.github.com/eddyb/5a75f8973d3d8018afd3). Sadly, there isn't a massive change in the memory used for compiling stage2 librustc (it doesn't go over **1.4GB** as [before](http://huonw.github.io/isrustfastyet/mem/), but I can barely see the difference). However, my own testcase (previously peaking at **1.6GB** in typeck) shows a reduction of **200**-**400MB**.

2013-09-09auto merge of #9005 : alexcrichton/rust/rusty-log, r=brsonbors-3/+3
Also redefine all of the standard logging macros to use more rust code instead of custom LLVM translation code. This makes them a bit easier to understand, but also more flexibile for future types of logging. Additionally, this commit removes the LogType language item in preparation for changing how logging is performed.

2013-09-06added gensym_copy mechanism to ensure sharing of pointers in the internerJohn Clements-40/+33
this makes comparisons constant-time, and enables spelling-comparison of identifiers, crucial in many parts of resolve.

this is necessary so that the new idents are connected to the original strings. this is important both for error messages, and so that top-level refs get connected to the right things.
