This moves `std::rand::distribitions::{Normal, StandardNormal}` to `...::distributions::normal`, reexporting `Normal` from `distributions` (and similarly for `Exp` and Exp1`), and adds:
- Log-normal
- Chi-squared
- F
- Student T
all of which are implemented in C++11's random library. Tests in 0424b8aded. Note that these are approximately half documentation & half implementation (of which a significant portion is boilerplate `}`'s and so on).
This implements parts of the changes to `Result` and `Option` I proposed and discussed in this thread: https://mail.mozilla.org/pipermail/rust-dev/2013-November/006254.html
This PR includes:
- Adding `ok()` and `err()` option adapters for both `Result` variants.
- Removing `get_ref`, `expect` and iterator constructors for `Result`, as they are reachable with the variant adapters.
- Removing `Result`s `ToStr` bound on the error type because of composability issues. (See https://mail.mozilla.org/pipermail/rust-dev/2013-November/006283.html)
- Some warning cleanups
In order to keep up to date with changes to the libraries that `llvm-config`
spits out, the dependencies to the LLVM are a dynamically generated rust file.
This file is now automatically updated whenever LLVM is updated to get kept
up-to-date.
At the same time, this cleans out some old cruft which isn't necessary in the
makefiles in terms of dependencies.

It's useful to allow users to get at the internal std::rc::comm::Port,
and other such fields, since they implement important traits like
Select.
See [rust-dev] "select on std::comm::Port and different types" at https://mail.mozilla.org/pipermail/rust-dev/2013-November/006735.html for background.
Right now, as pointed out in #8132, it is very easy to introduce a subtle race
in the runtime. I believe that this is the cause of the current flakiness on the
bots.
I have taken the last idea mentioned in that issue which is to use a lock around
descheduling and context switching in order to solve this race.

The `integer_decode()` function decodes a float (f32/f64)
into integers containing the mantissa, exponent and sign.
It's needed for `rationalize()` implementation of #9838.
The code got ported from ABCL [1].
[1] http://abcl.org/trac/browser/trunk/abcl/src/org/armedbear/lisp/FloatFunctions.java?rev=14465#L94
I got the permission to use this code for Rust from Peter Graves (the ABCL copyright holder) . If there's any further IP clearance needed, let me know.
This function had type &[u8] -> ~str, i.e. it allocates a string
internally, even though the non-allocating version that take &[u8] ->
&str and ~[u8] -> ~str are all that is necessary in most circumstances.
This registers new snapshots after the landing of #10528, and then goes on to tweak the build process to build a monolithic `rustc` binary for use in future snapshots. This mainly involved dropping the dynamic dependency on `librustllvm`, so that's now built as a static library (with a dynamically generated rust file listing LLVM dependencies).
This currently doesn't actually make the snapshot any smaller (24MB => 23MB), but I noticed that the executable has 11MB of metadata so once progress is made on #10740 we should have a much smaller snapshot.
There's not really a super-compelling reason to distribute just a binary because we have all the infrastructure for dealing with a directory structure, but to me it seems "more correct" that a snapshot compiler is just a `rustc` binary.
This method is the mutable version of ImmutableVector::split. It is
a DoubleEndedIterator, making mut_rsplit irrelevent. The size_hint
method is not optimal because of #9629.
At the same time, clarify *split* iterator doc.
mut_chunks() returns an iterator that produces mutable slices. This is the mutable version of the existing chunks() method on the ImmutableVector trait.
EDIT: This uses only safe code now.
PREVIOUSLY:
I tried to get this working with safe code only, but I couldn't figure out how to make that work. Before #8624, the exact same code worked without the need for the transmute() call. With that fix and without the transmute() call, the compiler complains about the call to mut_slice(). I think the issue is that the mutable slice that is returned will live longer than the self parameter since the self parameter doesn't have an explicit lifetime. However, that is the way that the Iterator trait defines the next() method. I'm sure there is a good reason for that, although I don't quite understand why. Anyway, I think the interface is safe, since the MutChunkIter will only hand out non-overlapping pointers and there is no way to get it to hand out the same pointer twice.
BufferedWriter::inner flushes before returning the underlying writer.
BufferedWriter::write no longer flushes the underlying writer.
LineBufferedWriter::write flushes up to the *last* newline in the input
string, not the first.

In this series of commits, I've implemented static linking for rust. The scheme I implemented was the same as my [mailing list post](https://mail.mozilla.org/pipermail/rust-dev/2013-November/006686.html).
The commits have more details to the nitty gritty of what went on. I've rebased this on top of my native mutex pull request (#10479), but I imagine that it will land before this lands, I just wanted to pre-emptively get all the rebase conflicts out of the way (becuase this is reorganizing building librustrt as well).
Some contentious points I want to make sure are all good:
* I've added more "compiler chooses a default" behavior than I would like, I want to make sure that this is all very clearly outlined in the code, and if not I would like to remove behavior or make it clearer.
* I want to make sure that the new "fancy suite" tests are ok (using make/python instead of another rust crate)
If we do indeed pursue this, I would be more than willing to write up a document describing how linking in rust works. I believe that this behavior should be very understandable, and the compiler should never hinder someone just because linking is a little fuzzy.
