2a86485277 auto merge of #5418 : luqmana/rust/stack-float, r=brson 
Like I commented in #2043, I can't reproduce the weirdness from #1388 on either mac or linux (x84_64) and pushing to try gives all green.

That's 128 less bytes to have to keep in the stack for every call to __morestack.

a5ddc00982 rustc: Use an out pointer to return structs in x86 C ABI. #5347 
This Adds a bunch of tests for passing and returning structs
of various sizes to C. It fixes the struct return rules on unix,
and on windows for structs of size > 8 bytes. Struct passing
on unix for structs under a certain size appears to still be broken.

c0be7df5de mark the assembly object stacks as non-executable 
Closes #5643

This also removes the need to pass noexecstack to gcc, but that wasn't
actually working anymore.

ef282dbe2a auto merge of #5409 : brson/rust/rt, r=brson 
r?

There are a lot of commits here, but not all that much substance. Mostly just refactoring.

I started sketching out the beginnings of a very simple I/O API in `core::rt::io` that represents I/O streams as a single `Stream` trait instead of `Reader` / `Writer` pairs. This seems to be the more common pattern (at least this is how the .NET BCL does it) and it seems to me that separate readers and writers would make duplex streams very awkward. Regardless, I don't intend to go very far down the I/O API design road without some mailing list discussion.

I've also started on the uv bindings for file I/O but haven't gotten very far.

Also hooked up the new scheduler to `rust_start` and the compiletest driver. 70% of run-pass test cases already pass, but I wouldn't read too much into that.

I also split the direct, low-level uv bindings in two so that the scheduler can have its own set, leaving `std::net` on its own.

6d4499ce4d auto merge of #5424 : luqmana/rust/inline-rt, r=brson 
As per #2521. Inlining seems to improve performance slightly:

                 Inlined          Not Inlined
    x86:         13.5482            14.4112
    x86_64:      17.4712            18.0696

(Average of 5 runs timed with `time`)

```Rust

fn foo() -> int {
    int::from_str(~"28098").unwrap()
}

fn main() {
    for 1000000.times {
        foo();
        foo();
        foo();
        foo();
        foo();
    }
}
```

All run on:

    Linux 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.35-2~bpo60+1 x86_64 GNU/Linux

The MIPS and ARM bits I didn't inline since I'm not as familiar with them and I also can't test them. All green on try.

efc7f82bc4 Revamp foreign code not to consider the Rust modes. This requires 
adjusting a few foreign functions that were declared with by-ref
mode.  This also allows us to remove by-val mode in the near future.

With copy mode, though, we have to be careful because Rust will implicitly pass
somethings by pointer but this may not be the C ABI rules.  For example, rust
will pass a struct Foo as a Foo*.  So I added some code into the adapters to
fix this (though the C ABI rules may put the pointer back, oh well).

This patch also includes a lint mode for the use of by-ref mode
in foreign functions as the semantics of this have changed.

0ad3a110be Work around linkage bug cross-compiling from x86_64-apple-darwin to i686-apple-darwin 
The correct opendir/readdir to use appear to be the 64-bit versions called
opendir$INODE64, etc. but for some reason I can't get them to link properly
on i686. Putting them in librustrt and making gcc figure it out works.
This mystery will have to wait for another day.

20fd0c53ed auto merge of #4938 : thestinger/rust/no_zero, r=brson 
I removed the unused wrappers methods named `calloc` because they relied on the malloc wrapper having a `bool zero = true` default parameter (which resulted in some accidental zeroing). Perhaps wrapping the actual calloc function would be useful, but I don't know of an existing use case that could use it so I just removed these.

This gives an ~1% performance improvement for TreeMap, which does a lot of small allocations. Vectors use `realloc` which didn't zero before these changes so there's no measurable change in performance.
