15164cc6a6 Issue the correct deref count for the implicit deref that occurs 
as part of an autoslice operation (#6272).

Fixes #6272.

7675856253 auto merge of #6354 : Aatch/rust/uninit-intrinsic, r=graydon 
Adds an `uninit` intrinsic.

It's just an empty function, so llvm optimizes it down to nothing.

I changed all of the `init` intrinsic usages to `uninit` where it seemed appropriate to.

dc2ca9d883 Refactor representation of bounds to separate out BuiltinBounds into 
its own type. Use a bitset to represent built-in bounds. There
are several places in the language where only builtin bounds (aka kinds)
will be accepted, e.g. on closures, destructor type parameters perhaps,
and on trait types.

1393c3a3f4 Use a specialized string interner to reduce the need for owned strings 
&str can be turned into @~str on demand, using to_owned(), so for
strings, we can create a specialized interner that accepts &str for
intern() and find() but stores and returns @~str.

Hi there,

Really enjoying Rust. Noticed a few typos so I searched around for a few more--here's some fixes.

Ran `make check` and got `summary of 24 test runs: 4868 passed; 0 failed; 330 ignored`.

Thanks!

5a65f51d66 auto merge of #6214 : sanxiyn/rust/simd-2, r=graydon 
At the moment this only includes type checking and there is no code generation support yet. I wanted to get the design reviewed first.

From discussion with @graydon at #5841, re-implemented as `#[simd]` attribute on structs.

Progressing towards #3499.

65ded84d20 auto merge of #6119 : brson/rust/main, r=brson 
r? @ILyoan

This pulls all the logic for discovering the crate entry point into a new pass (out of resolve and typeck), then changes it so that main is only looked for at the crate level (`#[main]` can still be used anywhere).

I don't understand the special android logic here and worry that I may have broken it.

Sorry this is so big, and sorry the first commit is just titled 'wip'.

Some interesting bits

* [LocalServices](f9069baa70) - This is the set of runtime capabilities that *all* Rust code should expect access to, including the local heap, GC, logging, unwinding.
* [impl Reader, etc. for Option](5fbb0949a5) - Constructors like `File::open` return Option<FileStream>. This lets you write I/O code without ever unwrapping an option.

This series adds a lot of [documentation](https://github.com/brson/rust/blob/io/src/libcore/rt/io/mod.rs#L11) to `core::rt::io`.

db6a62c537 rustc: Drop the visitor object from the visitor glue 
Recent demoding makes the visitor glue leak. It hasn't shown up in tests
because the box annihilator deletes the leaked boxes. This affects the
new scheduler though which does not yet have a box annihilator.

I don't think there's any great way to test this besides setting up
a task that doesn't run the box annihilator and I don't know that that's
a capability we want tasks to have.

The drop block has been deprecated for quite some time. This patch series removes support for parsing it and all the related machinery that made drop work.

As a side feature of all this, I also added the ability to annote fields in structs. This allows comments to be properly associated with an individual field. However, I didn't update `rustdoc` to integrate these comment blocks into the documentation it generates.

8408012ca4 The null case of a nullable-poiner enum might not be nullary. 
Cases like `Either<@int,()>` have a null case with at most one value but
a nonzero number of fields; if we misreport this, then bad things can
happen inside of, for example, pattern matching.

Closes #6117.

b085b51357 Offer a hint on some unresolved imports 
I didn't know how to use "use" initially, and an error message like this would
have solved quite a bit of frustration. I think this properly handles cases
where it's not appropriate but I'm not sure.

It seems that the general convention of error messages is to have keywords in backticks, so it's probably a good idea to keep doing that.

Closes #3083.

This takes a similar approach to #5797 where a set is present on the `tcx` of used mutable definitions. Everything is by default warned about, and analyses must explicitly add mutable definitions to this set so they're not warned about.

Most of this was pretty straightforward, although there was one caveat that I ran into when implementing it. Apparently when the old modes are used (or maybe `legacy_modes`, I'm not sure) some different code paths are taken to cause spurious warnings to be issued which shouldn't be issued. I'm not really sure how modes even worked, so I was having a lot of trouble tracking this down. I figured that because they're a legacy thing that I'd just de-mode the compiler so that the warnings wouldn't be a problem anymore (or at least for the compiler).

Other than that, the entire compiler compiles without warnings of unused mutable variables. To prevent bad warnings, #5965 should be landed (which in turn is waiting on #5963) before landing this. I figured I'd stick it out for review anyway though.

As the name suggests this replaces many instances of cast::reinterpret_cast by cast::transmute. It's essentially the boring part of fixing #5163, the remaining reinterpret_casts should be more tricky to remove (unless I missed a boring case).
