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.
This commit adds support for the compiler to distinguish between different forms
of lookup paths in the compiler itself. Issue #19767 has some background on this
topic, as well as some sample bugs which can occur if these lookup paths are not
separated.
This commits extends the existing command line flag `-L` with the same trailing
syntax as the `-l` flag. Each argument to `-L` can now have a trailing `:all`,
`:native`, `:crate`, or `:dependency`. This suffix indicates what form of lookup
path the compiler should add the argument to. The `dependency` lookup path is
used when looking up crate dependencies, the `crate` lookup path is used when
looking for immediate dependencies (`extern crate` statements), and the `native`
lookup path is used for probing for native libraries to insert into rlibs. Paths
with `all` are used for all of these purposes (the default).
The default compiler lookup path (the rustlib libdir) is by default added to all
of these paths. Additionally, the `RUST_PATH` lookup path is added to all of
these paths.
Closes#19767
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.
[RFC 344]: https://github.com/rust-lang/rfcs/blob/master/text/0344-conventions-galore.md
[breaking-change]
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].
