c119903f62 auto merge of #13222 : nick29581/rust/dxr4, r=brson
Adds a -Z flag `save-analysis` which runs after the analysis phase of the compiler and saves a bunch of info into a CSV file for the crate. This is designed to work with the DXR code browser, but is frontend-independent, that is this info should be useful for all kinds of code browsers, IDEs, or other tools.

I need to squash commits before landing (there will probably be a fair few to come), please ignore them for now and just comment on the changes.

984e9afae5 Dump results of analysis phase as CSV
Adds the option -Zsave-analysis which will dump the results of syntax and type checking into CSV files. These can be interpreted by tools such as DXR to provide semantic information about Rust programs for code search, cross-reference, etc.

c20aed0930 auto merge of #14819 : michaelwoerister/rust/unique_type_id, r=alexcrichton
With this change, rustc creates a unique type identifier for types in debuginfo. These type identifiers are used by LLVM to correctly handle link-time-optimization scenarios but also help rustc with dealing with inlining from other crates. For more information, see the documentation block at the top of librustc/middle/trans/debuginfo.rs and also [my blog post about the topic](http://michaelwoerister.github.io/2014/06/05/rust-debuginfo-and-unique-type-identifiers.html). This should fix the LTO issues that have been popping up lately. 

The changes to the debuginfo module's inner workings are also improved by this. Metadata uniquing of pointer types is not handled explicitly instead of relying on LLVM doing the right thing behind the scenes, and region parameters on types should not lead to metadata duplication anymore.

There are two things that I'd like to get some feedback on:
1. IDs for named items consist of two parts: The [Strict Version Hash](https://github.com/mozilla/rust/blob/0.10/src/librustc/back/svh.rs#L11) of their defining crate and the AST node id of their definition within that crate. My question is: Is the SVH a good choice for identifying the crate? Is it even going to stay? The [crate-id RFC](https://github.com/rust-lang/rfcs/pull/109) got me confused.
2. Unique Type Identifiers can be arbitrary strings and right now the format is rather verbose. For debugging this is nice, because one can infer a lot about a type from the type id alone (it's more or less a signature). For deeply nested generics, id strings could get rather long though. One option to limit the id size would be to use some hashcode instead of the full id (anything that avoids collision as much as possible). Another option would be to use a more compact representation, like ty_encode. This reduces size but also readability.
Since these ID's only show up in LLVM IR, I'm inclined to just leave in the verbose format for now, and only act if sizes of rlibs become a problem.

8b87c3a2a8 auto merge of #14809 : zzmp/rust/patch-2, r=alexcrichton
Previously, the type system's restrictions on borrowing were summarized as

> The previous example showed that the type system forbids any borrowing of owned boxes found in aliasable, mutable memory.

This did not jive with the example, which allowed mutations so long as the borrowed reference had been returned. Also, the language has changed to no longer allow aliasable mutable locations. This changes the summary to read

> The previous example showed that the type system forbids mutations of owned boxed values while they are being borrowed. In general, the type system also forbids borrowing a value as mutable if it is already being borrowed - either as a mutable reference or an immutable one.

This adds more general information for the experienced reader as well, to offer a more complete understanding.

The guide previously stated:

> The compiler will automatically convert a box box point to a reference like &point.

This fixes the doubled word `box`, so the statement reads

> The compiler will automatically convert a box point to a reference like &point.

The code it is referring to is `compute_distance(&on_the_stack, on_the_heap);`, so a single `box` is appropriate.

f9260d41d6 auto merge of #14746 : alexcrichton/rust/libsync, r=brson
This commit is the final step in the libstd facade, #13851. The purpose of this
commit is to move libsync underneath the standard library, behind the facade.
This will allow core primitives like channels, queues, and atomics to all live
in the same location.

There were a few notable changes and a few breaking changes as part of this
movement:

* The `Vec` and `String` types are reexported at the top level of libcollections
* The `unreachable!()` macro was copied to libcore
* The `std::rt::thread` module was moved to librustrt, but it is still
  reexported at the same location.
* The `std::comm` module was moved to libsync
* The `sync::comm` module was moved under `sync::comm`, and renamed to `duplex`.
  It is now a private module with types/functions being reexported under
  `sync::comm`. This is a breaking change for any existing users of duplex
  streams.
* All concurrent queues/deques were moved directly under libsync. They are also
  all marked with #![experimental] for now if they are public.
* The `task_pool` and `future` modules no longer live in libsync, but rather
  live under `std::sync`. They will forever live at this location, but they may
  move to libsync if the `std::task` module moves as well.

This commit removes `@T` from the compiler by moving the AST to using `Gc<T>`. This also starts treating `Gc<T>` as `@T` in the same way that `Box<T>` is the same as `~T` in the compiler.

After this hits a snapshot, the `@T` syntax should be able to be removed completely.

531ed3d599 rustc: Update how Gc<T> is recognized
This commit uses the same trick as ~/Box to map Gc<T> to @T internally inside
the compiler. This moves a number of implementations of traits to the `gc`
module in the standard library.

This removes functions such as `Gc::new`, `Gc::borrow`, and `Gc::ptr_eq` in
favor of the more modern equivalents, `box(GC)`, `Deref`, and pointer equality.

The Gc pointer itself should be much more useful now, and subsequent commits
will move the compiler away from @T towards Gc<T>
