2013-12-15libsyntax: Implement the new `box` syntax for unique pointers.Patrick Walton-7/+9
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.

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.

2013-08-11syntax: Shrink enum Token and enum nonterminalblake2-ppc-4/+4
`enum Token` was 192 bytes (64-bit), as pointed out by pnkfelix; the only bloating variant being `INTERPOLATED(nonterminal)`. Updating `enum nonterminal` to use ~ where variants included big types, shrunk size_of(Token) to 32 bytes (64-bit). I am unsure if the `nt_ident` variant should have an indirection, with ast::ident being only 16 bytes (64-bit), but without this, enum Token would be 40 bytes. A dumb benchmark says that compilation time is unchanged, while peak memory usage for compiling std.rs is down 3% Before:: $ time ./x86_64-unknown-linux-gnu/stage1/bin/rustc --cfg stage1 src/libstd/std.rs 19.00user 0.39system 0:19.41elapsed 99%CPU (0avgtext+0avgdata 627820maxresident)k 0inputs+28896outputs (0major+228665minor)pagefaults 0swaps $ time ./x86_64-unknown-linux-gnu/stage1/bin/rustc -O --cfg stage1 src/libstd/std.rs 31.64user 0.34system 0:32.02elapsed 99%CPU (0avgtext+0avgdata 629876maxresident)k 0inputs+22432outputs (0major+229411minor)pagefaults 0swaps After:: $ time ./x86_64-unknown-linux-gnu/stage1/bin/rustc --cfg stage1 src/libstd/std.rs 19.07user 0.45system 0:19.55elapsed 99%CPU (0avgtext+0avgdata 609384maxresident)k 0inputs+28896outputs (0major+221997minor)pagefaults 0swaps $ time ./x86_64-unknown-linux-gnu/stage1/bin/rustc -O --cfg stage1 src/libstd/std.rs 31.90user 0.34system 0:32.28elapsed 99%CPU (0avgtext+0avgdata 612080maxresident)k 0inputs+22432outputs (0major+223726minor)pagefaults 0swaps
