bb18a3cfe7 Drop support for LLVM < 3.5 and fix compile errors with 3.5
LLVM older that 3.6 has a bug that cause assertions when compiling certain
constructs. For 3.5 there's still a chance that the bug might get fixed
in 3.5.2, so let's keep allowing to compile with it for it for now.

b09e5daa89 Split rustdoc summary lines in a smarter way
Previously it would fail on a trivial case like

    /// Summary line
    /// <trailing space>
    /// Regular content

Compliant markdown preprocessor would render that as two separate paragraphs, but our summary line
extractor would interpret both lines as the same paragraph and include both into the short summary.

at least that's what the docs say: http://doc.rust-lang.org/std/slice/fn.from_raw_parts.html

A few situations got prettier. In some situations the mutability of the resulting and source pointers differed (and was cast away by transmute), the mutability matches now.

85b084f4bd Reject -L "", -L native=, and other empty search paths.
It wasn't clear to me that early_error was correct here, but it seems to
work. This code is reachable from `rustdoc`, which is problematic, because
early_error panics. rustc handles the panics gracefully (without ICEing or
crashing), but rustdoc does not. It's not the first such rustdoc problem,
though:

    $ rustdoc hello.rs --extern std=bad-std
    error: extern location for std does not exist: bad-std
    hello.rs:1:1: 1:1 error: can't find crate for `std`

f7453f940b Auto merge of #22948 - rprichard:simple-panic-opt, r=alexcrichton
Reduce code size overhead from core::panicking::panic

core::panicking::panic currently creates an Arguments structure using
format_args!("{}", expr), which formats the expr str using the Display::fmt.
Display::fmt pulls in Formatter::pad, which then also pulls in string-related
code for truncation and padding.

If core::panicking::panic instead creates an Arguments structure with a string
piece, it is possible that the Display::fmt function for str can be optimized
out of the program.

In my testing with a 32-bit x86 bare metal program, the change tended to save
between ~100 bytes and ~5500 bytes, depending on what other panic* functions
the program invokes and whether the panic_fmt lang item uses the Arguments
value.

f798674b86 std: Stabilize the net module
This commit performs a stabilization pass over the std::net module,
incorporating the changes from RFC 923. Specifically, the following actions were
taken:

Stable functionality:

* `net` (the name)
* `Shutdown`
* `Shutdown::{Read, Write, Both}`
* `lookup_host`
* `LookupHost`
* `SocketAddr`
* `SocketAddr::{V4, V6}`
* `SocketAddr::port`
* `SocketAddrV4`
* `SocketAddrV4::{new, ip, port}`
* `SocketAddrV6`
* `SocketAddrV4::{new, ip, port, flowinfo, scope_id}`
* Common trait impls for socket addr structures
* `ToSocketAddrs`
* `ToSocketAddrs::Iter`
* `ToSocketAddrs::to_socket_addrs`
* `ToSocketAddrs for {SocketAddr*, (Ipv*Addr, u16), str, (str, u16)}`
* `Ipv4Addr`
* `Ipv4Addr::{new, octets, to_ipv6_compatible, to_ipv6_mapped}`
* `Ipv6Addr`
* `Ipv6Addr::{new, segments, to_ipv4}`
* `TcpStream`
* `TcpStream::connect`
* `TcpStream::{peer_addr, local_addr, shutdown, try_clone}`
* `{Read,Write} for {TcpStream, &TcpStream}`
* `TcpListener`
* `TcpListener::bind`
* `TcpListener::{local_addr, try_clone, accept, incoming}`
* `Incoming`
* `UdpSocket`
* `UdpSocket::bind`
* `UdpSocket::{recv_from, send_to, local_addr, try_clone}`

Unstable functionality:

* Extra methods on `Ipv{4,6}Addr` for various methods of inspecting the address
  and determining qualities of it.
* Extra methods on `TcpStream` to configure various protocol options.
* Extra methods on `UdpSocket` to configure various protocol options.

Deprecated functionality:

* The `socket_addr` method has been renamed to `local_addr`

This commit is a breaking change due to the restructuring of the `SocketAddr`
type as well as the renaming of the `socket_addr` method. Migration should be
fairly straightforward, however, after accounting for the new level of
abstraction in `SocketAddr` (protocol distinction at the socket address level,
not the IP address).

00211ecfda Avoid passing -L "" during cross-compilation.
LLVM_LIBDIR_<triple> is only defined for host triples, not target triples.

FWIW, the same is true for LLVM_STDCPP_RUSTFLAGS_<triple>, where we
explicitly define it as empty when --enable-llvm-static-stdcpp is not
specified, but it's still undefined for cross-compiled triples.

1d5983aded Deprecate range, range_step, count, distributions
This commit deprecates the `count`, `range` and `range_step` functions
in `iter`, in favor of range notation. To recover all existing
functionality, a new `step_by` adapter is provided directly on `ops::Range`
and `ops::RangeFrom`.

3e4be02b80 Auto merge of #23292 - alexcrichton:stabilize-io, r=aturon
The new `std::io` module has had some time to bake now, and this commit
stabilizes its functionality. There are still portions of the module which
remain unstable, and below contains a summart of the actions taken.

This commit also deprecates the entire contents of the `old_io` module in a
blanket fashion. All APIs should now have a reasonable replacement in the
new I/O modules.

Stable APIs:

* `std::io` (the name)
* `std::io::prelude` (the name)
* `Read`
* `Read::read`
* `Read::{read_to_end, read_to_string}` after being modified to return a `usize`
  for the number of bytes read.
* `ReadExt`
* `Write`
* `Write::write`
* `Write::{write_all, write_fmt}`
* `WriteExt`
* `BufRead`
* `BufRead::{fill_buf, consume}`
* `BufRead::{read_line, read_until}` after being modified to return a `usize`
  for the number of bytes read.
* `BufReadExt`
* `BufReader`
* `BufReader::{new, with_capacity}`
* `BufReader::{get_ref, get_mut, into_inner}`
* `{Read,BufRead} for BufReader`
* `BufWriter`
* `BufWriter::{new, with_capacity}`
* `BufWriter::{get_ref, get_mut, into_inner}`
* `Write for BufWriter`
* `IntoInnerError`
* `IntoInnerError::{error, into_inner}`
* `{Error,Display} for IntoInnerError`
* `LineWriter`
* `LineWriter::{new, with_capacity}` - `with_capacity` was added
* `LineWriter::{get_ref, get_mut, into_inner}` - `get_mut` was added)
* `Write for LineWriter`
* `BufStream`
* `BufStream::{new, with_capacities}`
* `BufStream::{get_ref, get_mut, into_inner}`
* `{BufRead,Read,Write} for BufStream`
* `stdin`
* `Stdin`

* `Stdin::read_line` - added method
* `StdinLock`

* `Write for Stderr`
* `Write for StderrLock`
* `io::Result`
* `io::Error`
* `io::Error::last_os_error`
* `{Display, Error} for Error`

Unstable APIs:

(reasons can be found in the commit itself)

* `Write::flush`
* `Seek`
* `ErrorKind`
* `Error::new`
* `Error::from_os_error`
* `Error::kind`

Deprecated APIs

* `Error::description` - available via the `Error` trait
* `Error::detail` - available via the `Display` implementation
* `thread::Builder::{stdout, stderr}`

Changes in functionality:

* `old_io::stdio::set_stderr` is now a noop as the infrastructure for printing
  backtraces has migrated to `std::io`.

about malloc and adds the attribute itself.

Use `boxed::into_raw` instead of `mem::transmute`.

I removed the `let my_num: *const i32 = mem::transmute(my_num);` case altogether because we own the box, a `*mut` pointer is good anywhere a `*const` is needed, `from_raw` takes a mutable pointer and casting from a `*const` caused an ICE.

This commit stabilizes essentially all of the new `std::path` API. The
API itself is changed in a couple of ways (which brings it in closer
alignment with the RFC):

* `.` components are now normalized away, unless they appear at the
  start of a path. This in turn effects the semantics of e.g. asking for
  the file name of `foo/` or `foo/.`, both of which yield `Some("foo")`
  now. This semantics is what the original RFC specified, and is also
  desirable given early experience rolling out the new API.

* The `parent` method is now `without_file` and succeeds if, and only
  if, `file_name` is `Some(_)`. That means, in particular, that it fails
  for a path like `foo/../`. This change affects `pop` as well.

In addition, the `old_path` module is now deprecated.

c9b03c24ec Auto merge of #23265 - eddyb:meth-ast-refactor, r=nikomatsakis
The end result is that common fields (id, name, attributes, etc.) are stored in now-structures `ImplItem` and `TraitItem`.
The signature of a method is no longer duplicated between methods with a body (default/impl) and those without, they now share `MethodSig`.

This is also a [breaking-change] because of minor bugfixes and changes to syntax extensions:
* `pub fn` methods in a trait no longer parse - remove the `pub`, it has no meaning anymore
* `MacResult::make_methods` is now `make_impl_items` and the return type has changed accordingly
* `quote_method` is gone, because `P<ast::Method>` doesn't exist and it couldn't represent a full method anyways - could be replaced by `quote_impl_item`/`quote_trait_item` in the future, but I do hope we realize how silly that combinatorial macro expansion is and settle on a single `quote` macro + some type hints - or just no types at all (only token-trees)
