Adds support for all variants of ast::WherePredicate in clean/mod.rs. Fixes#20048, but will need modification when EqualityPredicates are fully implemented in #20041.
Rename `FPCategory` to `FpCategory` and `Fp* to `*` in order to adhere to the
naming convention
This is a [breaking-change].
Existing code like this:
```
use std::num::{FPCategory, FPNaN};
```
should be adjusted to this:
```
use std::num::FpCategory as Fp
```
In the following code you can use the constants `Fp::Nan`, `Fp::Normal`, etc.
According to [RFC 344][], methods that return `&[u8]` should have names
ending in `bytes`. Though `include_bin!` is a macro not a method, it
seems reasonable to follow the convention anyway.
We keep the old name around for now, but trigger a deprecation warning
when it is used.

The previous behaviour of using the smallest type possible caused LLVM
to treat padding too conservatively, causing poor codegen. This commit
changes the behaviour to use an type-alignment-sized integer as the
discriminant. This keeps types the same size, but helps LLVM understand
the data structure a little better, resulting in better codegen.
RFC 248? I think you meant RFC 438.
There ain’t an RFC 248, while 438 looks to be what is being referred to:

Chis Morgan has a pretty important documentation fix in #19385 and he hasn't responded in a while to that pull request so I rebased it for him
Closes#19385
Part of #19253
I would have removed this public reexport in #19842, but #19812 hadn't merged (and snapshotted) at the time
In #19407, I changed the codebase to stop utilizing this reexport
[breaking-change]
This is an updated version of #19711. The merge and subsequent rebase on that branch were more trouble than they were worth, so I am just resubmitting the relevant change here.
If this PR is accepted, then #19711 can be closed.

This pull request updates the rustc manual page to represent current state of rustc option handling better. Moved the apparently deprecated options (#19900) to their own section and added all the new codegen options.
A bit unrelatedly, I also updated description of `-O` and `-g` flags to point to the new codegen options rather than old, deprecated ones.
Fixes#20111.
Now that #19448 has landed in a snapshot, we can add proper by-value operator overloads for `HashSet`. The behavior of these operator overloads is consistent with rust-lang/rfcs#235.
Internally refactor all mentions of `notrust` to the
positive statement `rust`.
[breaking-change] Change remaining `notrust` markers to
the thing they actually represent, e.g. `sh` or `plain`.
This supersedes #19693 .
This pull request:
*Renames `BinaryHeap::top` to `BinaryHeap::peek`
*Stabilizes `front/back/front_mut/back_mut` in `DList` and `RingBuf`
*Stabilizes `swap` in `RingBuf`
in accordance with rust-lang/rfcs#509.
Note that this PR does not address `Bitv::{get,set}` or HashMap's iterators, nor does it move `std::vec` to `std::collections::vec`, all of which still need to be done.
Because of the method renaming, this is a [breaking-change].
This commit completes the deprecation story for the in-tree serialization
library. The compiler will now emit a warning whenever it encounters
`deriving(Encodable)` or `deriving(Decodable)`, and the library itself is now
marked `#[unstable]` for when feature staging is enabled.
All users of serialization can migrate to the `rustc-serialize` crate on
crates.io which provides the exact same interface as the libserialize library
in-tree. The new deriving modes are named `RustcEncodable` and `RustcDecodable`
and require `extern crate "rustc-serialize" as rustc_serialize` at the crate
root in order to expand correctly.
To migrate all crates, add the following to your `Cargo.toml`:
[dependencies]
rustc-serialize = "0.1.1"
And then add the following to your crate root:
extern crate "rustc-serialize" as rustc_serialize;
Finally, rename `Encodable` and `Decodable` deriving modes to `RustcEncodable`
and `RustcDecodable`.

This commit starts out by consolidating all `str` extension traits into one
`StrExt` trait to be included in the prelude. This means that
`UnicodeStrPrelude`, `StrPrelude`, and `StrAllocating` have all been merged into
one `StrExt` exported by the standard library. Some functionality is currently
duplicated with the `StrExt` present in libcore.
This commit also currently avoids any methods which require any form of pattern
to operate. These functions will be stabilized via a separate RFC.
Next, stability of methods and structures are as follows:
Stable
* from_utf8_unchecked
* CowString - after moving to std::string
* StrExt::as_bytes
* StrExt::as_ptr
* StrExt::bytes/Bytes - also made a struct instead of a typedef
* StrExt::char_indices/CharIndices - CharOffsets was renamed
* StrExt::chars/Chars
* StrExt::is_empty
* StrExt::len
* StrExt::lines/Lines
* StrExt::lines_any/LinesAny
* StrExt::slice_unchecked
* StrExt::trim
* StrExt::trim_left
* StrExt::trim_right
* StrExt::words/Words - also made a struct instead of a typedef
Unstable
* from_utf8 - the error type was changed to a `Result`, but the error type has
yet to prove itself
* from_c_str - this function will be handled by the c_str RFC
* FromStr - this trait will have an associated error type eventually
* StrExt::escape_default - needs iterators at least, unsure if it should make
the cut
* StrExt::escape_unicode - needs iterators at least, unsure if it should make
the cut
* StrExt::slice_chars - this function has yet to prove itself
* StrExt::slice_shift_char - awaiting conventions about slicing and shifting
* StrExt::graphemes/Graphemes - this functionality may only be in libunicode
* StrExt::grapheme_indices/GraphemeIndices - this functionality may only be in
libunicode
* StrExt::width - this functionality may only be in libunicode
* StrExt::utf16_units - this functionality may only be in libunicode
* StrExt::nfd_chars - this functionality may only be in libunicode
* StrExt::nfkd_chars - this functionality may only be in libunicode
* StrExt::nfc_chars - this functionality may only be in libunicode
* StrExt::nfkc_chars - this functionality may only be in libunicode
* StrExt::is_char_boundary - naming is uncertain with container conventions
* StrExt::char_range_at - naming is uncertain with container conventions
* StrExt::char_range_at_reverse - naming is uncertain with container conventions
* StrExt::char_at - naming is uncertain with container conventions
* StrExt::char_at_reverse - naming is uncertain with container conventions
* StrVector::concat - this functionality may be replaced with iterators, but
it's not certain at this time
* StrVector::connect - as with concat, may be deprecated in favor of iterators
Deprecated
* StrAllocating and UnicodeStrPrelude have been merged into StrExit
* eq_slice - compiler implementation detail
* from_str - use the inherent parse() method
* is_utf8 - call from_utf8 instead
* replace - call the method instead
* truncate_utf16_at_nul - this is an implementation detail of windows and does
not need to be exposed.
* utf8_char_width - moved to libunicode
* utf16_items - moved to libunicode
* is_utf16 - moved to libunicode
* Utf16Items - moved to libunicode
* Utf16Item - moved to libunicode
* Utf16Encoder - moved to libunicode
* AnyLines - renamed to LinesAny and made a struct
* SendStr - use CowString<'static> instead
* str::raw - all functionality is deprecated
* StrExt::into_string - call to_string() instead
* StrExt::repeat - use iterators instead
* StrExt::char_len - use .chars().count() instead
* StrExt::is_alphanumeric - use .chars().all(..)
* StrExt::is_whitespace - use .chars().all(..)
Pending deprecation -- while slicing syntax is being worked out, these methods
are all #[unstable]
* Str - while currently used for generic programming, this trait will be
replaced with one of [], deref coercions, or a generic conversion trait.
* StrExt::slice - use slicing syntax instead
* StrExt::slice_to - use slicing syntax instead
* StrExt::slice_from - use slicing syntax instead
* StrExt::lev_distance - deprecated with no replacement
Awaiting stabilization due to patterns and/or matching
* StrExt::contains
* StrExt::contains_char
* StrExt::split
* StrExt::splitn
* StrExt::split_terminator
* StrExt::rsplitn
* StrExt::match_indices
* StrExt::split_str
* StrExt::starts_with
* StrExt::ends_with
* StrExt::trim_chars
* StrExt::trim_left_chars
* StrExt::trim_right_chars
* StrExt::find
* StrExt::rfind
* StrExt::find_str
* StrExt::subslice_offset
