Rename task::yield() to task::deschedule(). Fixes #8494.
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

2013-07-14Make TLS keys actually take up spaceAlex Crichton-1/+2
If the TLS key is 0-sized, then the linux linker is apparently smart enough to put everything at the same pointer. OSX on the other hand, will reserve some space for all of them. To get around this, the TLS key now actuall consumes space to ensure that it gets a unique pointer

New snapshot means this can all go. Also removes places that have comments that say they are workarounds for stage0 errors.

2013-06-13Use @str instead of @~str in libsyntax and librustc. Fixes #5048.Huon Wilson-27/+11
This almost removes the StringRef wrapper, since all strings are Equiv-alent now. Removes a lot of `/* bad */ copy *`'s, and converts several things to be &'static str (the lint table and the intrinsics table). There are many instances of .to_managed(), unfortunately.

2013-05-30Remove unnecessary 'use' formsDaniel Farina-3/+1
Fix a laundry list of warnings involving unused imports that glutted up compilation output. There are more, but there seems to be some false positives (where 'remedy' appears to break the build), but this particular set of fixes seems safe.

2013-05-25Use an enum for keywords and intern them to improve parser performanceBjörn Steinbrink-45/+156
Currently, keywords are stored in hashsets that are recreated for every Parser instance, which is quite expensive since macro expansion creates lots of them. Additionally, the parser functions that look for a keyword currently accept a string and have a runtime check to validate that they actually received a keyword. By creating an enum for the keywords and inserting them into the ident interner, we can avoid the creation of the hashsets and get static checks for the keywords. For libstd, this cuts the parse+expansion part from ~2.6s to ~1.6s.
