2013-09-10Delay assignment of node ids until after expansion. Ensures that each AST nodeNiko Matsakis-318/+360
has a unique id. Fixes numerous bugs in macro expansion and deriving. Add two representative tests. Fixes #7971 Fixes #6304 Fixes #8367 Fixes #8754 Fixes #8852 Fixes #2543 Fixes #7654
2013-09-10auto merge of #9090 : jbclements/rust/let-var-hygiene, r=luqmanabors-13/+2
This appears to fix issue #9049. It also re-enables the ICE check on comparing idents for equality; it appears that ICEs are better than seg faults.
2013-09-10Remove oldvisit.rs (yay!); part of #7081 refactoring.Felix S. Klock II-780/+0
2013-09-09auto merge of #9062 : blake2-ppc/rust/vec-iterator, r=alexcrichtonbors-1/+1
Visit the free functions of std::vec and reimplement or remove some. Most prominently, remove `each_permutation` and replace with two iterators, ElementSwaps and Permutations. Replace unzip, unzip_slice with an updated `unzip` that works with an iterator argument. Replace each_permutation with a Permutation iterator. The new permutation iterator is more efficient since it uses an algorithm that produces permutations in an order where each is only one element swap apart, including swapping back to the original state with one swap at the end. Unify the seldomly used functions `build`, `build_sized`, `build_sized_opt` into just one function `build`. Remove `equal_sizes`
2013-09-09undo cowardly hiding of eq-checkJohn Clements-13/+2
I've reversed my thinking on this restrictive definition of eq after two separate bugs were hidden by commenting it out; it's better to get ICEs than SIGSEGV's, any day. RE-ENABLING ICE MACHINE!
2013-09-10std::at_vec and vec: Unify build_sized, build_sized_opt into buildblake2-ppc-1/+1
These functions have very few users since they are mostly replaced by iterator-based constructions. Convert a few remaining users in-tree, and reduce the number of functions by basically renaming build_sized_opt to build, and removing the other two. This for both the vec and the at_vec versions.
2013-09-09auto merge of #9034 : catamorphism/rust/rustpkg-workcache, r=metajackbors-78/+9
r? @metajack or @brson - This pull request makes rustpkg use the workcache library to avoid recompilation.
2013-09-09auto merge of #9005 : alexcrichton/rust/rusty-log, r=brsonbors-83/+49
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.
2013-09-08rustpkg: Use workcacheTim Chevalier-78/+9
rustpkg now uses the workcache library to avoid recompilation. Hooray!
2013-09-08Fix pretty-printing of empty impl itemsJakub-1/+3
2013-09-08syntax: aesthetic improvements to the `for` desugaring.Huon Wilson-130/+38
2013-09-08syntax: implement labelled breaks for `for`.Huon Wilson-15/+25
`for` desugars to `loop` so it is trivial to just desugar to `loop` while retaining any label.
2013-09-08auto merge of #9035 : alexcrichton/rust/fewer-clownshoes, r=huonwbors-23/+23
This removes another large chunk of this odd 'clownshoes' identifier showing up in symbol names. These all originated from external crates because the encoded items were encoded independently of the paths calculated in ast_map. The encoding of these paths now uses the helper function in ast_map to calculate the "pretty name" for an impl block. Unfortunately there is still no information about generics in the symbol name, but it's certainly vastly better than before hash::__extensions__::write::_version::v0.8 becomes hash::Writer$SipState::write::hversion::v0.8 This also fixes bugs in which lots of methods would show up as `meth_XXX`, they now only show up as `meth` and throw some extra characters onto the version string.

2013-09-06quote_* macros no longer need to be capturingJohn Clements-91/+19
This is actually almost a problem, because those were my poster-child macros for "here's how to implement a capturing macro." Following this change, there will be no macros that use capturing; this will probably make life unpleasant for the first person that wants to implement a capturing macro. I should probably create a dummy_capturing macro, just to show how it works.
