Boolean values and small aggregates have a different type in
args/allocas than in SSA values but the intrinsics for volatile and
atomic ops were missing the necessary casts to handle that.
Fixes#23550
This commit removes the reexports of `old_io` traits as well as `old_path` types
and traits from the prelude. This functionality is now all deprecated and needs
to be removed to make way for other functionality like `Seek` in the `std::io`
module (currently reexported as `NewSeek` in the io prelude).

This is temporarily rebased on #23245 as it would otherwise conflict, the last commit is the only one relevant to this PR though.
We don't use 'task' anymore, these are now threads.
Because this changes the name of a compiler option, this is
[breaking-change]
I think this is small enough to not need an RFC, nor a period of accepting both. If we want to take both for a while, I can change the patch.
This should solve issues #23115, #23469, and #23407.
As the title says, this is just a workaround. The underlying problem is that macro expansion can produce invalid spans. I've opened issue #23480 so we don't forget about that.
* rustdoc was doubly appending the file name to the path of where to
generate the source files, meanwhile, the [src] hyperlinks were not
* Added a flag to rustdoc::html::render::clean_srcpath to ignore the
last path component, i.e. the file name itself to prevent the issue
* This also avoids creating directories with the same name as source
files, and it makes sure the link to `main.css` is correct as well.
Fixes#23192
Require braces when a closure has an explicit return type. This is a [breaking-change]: instead of a closure like `|| -> i32 22`, prefer `|| -> i32 { 22 }`.
Fixes#23420.
* no_split_stack was renamed to no_stack_check
* deriving was renamed to derive
* `use foo::mod` was renamed to `use foo::self`;
* legacy lifetime definitions in closures have been replaced with `for` syntax
* `fn foo() -> &A + B` has been deprecated for some time (needs parens)
* Obsolete `for Sized?` syntax
* Obsolete `Sized? Foo` syntax
* Obsolete `|T| -> U` syntax

Fixes#23192
This patch changes the type of byte string literals from `&[u8]` to `&[u8; N]`.
It also implements some necessary traits (`IntoBytes`, `Seek`, `Read`, `BufRead`) for fixed-size arrays (also related to #21725) and adds test for #17233, which seems to be resolved.
Fixes#18465

Safe fns are no longer subtypes of unsafe fns, but you can coerce from one to the other.
This is a [breaking-change] in that impl fns must now be declared `unsafe` if the trait is declared `unsafe`. In some rare cases, the subtyping change may also direct affect you, but no such cases were encountered in practice.
Fixes#23449.

This upcast coercion currently never requires vtable changes. It should be generalized.
This is a [breaking-change] -- if you have an impl on an object type like `impl SomeTrait`, then this will no longer be applicable to object types like `SomeTrait+Send`. In the standard library, this primarily affected `Any`, and this PR adds impls for `Any+Send` as to keep the API the same in practice. An alternate workaround is to use UFCS form or standalone fns. For more details, see <https://github.com/rust-lang/rust/issues/18737#issuecomment-78450798>.

This upcast coercion currently preserves the vtable for the object, but
eventually it can be used to create a derived vtable. The upcast
coercion is not introduced into method dispatch; see comment on #18737
for information about why. Fixes#18737.
- Allow inherent implementations on `char`, `str`, `[T]`, `*const T`, `*mut T` and all the numeric primitives.
- copy `unicode::char::CharExt` methods into `impl char`
- remove `unicode::char::CharExt`, its re-export `std::char::CharExt` and `CharExt` from the prelude
- copy `collections::str::StrExt` methods into `impl str`
- remove `collections::str::StrExt` its re-export `std::str::StrExt`, and `StrExt` from the prelude
- copy `collections::slice::SliceExt` methods into `impl<T> [T]`
- remove `collections::slice::SliceExt` its re-export `std::slice::SliceExt`, and `SliceExt` from the prelude
- copy `core::ptr::PtrExt` methods into `impl<T> *const T`
- remove `core::ptr::PtrExt` its re-export `std::ptr::PtrExt`, and `PtrExt` from the prelude
- copy `core::ptr::PtrExt` and `core::ptr::MutPtrExt` methods into `impl<T> *mut T`
- remove `core::ptr::MutPtrExt` its re-export `std::ptr::MutPtrExt`, and `MutPtrExt` from the prelude
- copy `core::num::Int` and `core::num::SignedInt` methods into `impl i{8,16,32,64,size}`
- copy `core::num::Int` and `core::num::UnsignedInt` methods into `impl u{8,16,32,64,size}`
- remove `core::num::UnsignedInt` and its re-export `std::num::UnsignedInt`
- move `collections` tests into its own crate: `collectionstest`
- copy `core::num::Float` methods into `impl f{32,64}`
Because this PR removes several traits, this is a [breaking-change], however functionality remains unchanged and breakage due to unresolved imports should be minimal. If you encounter an error due to an unresolved import, simply remove the import:
``` diff
fn main() {
- use std::num::UnsignedInt; //~ error: unresolved import `std::num::UnsignedInt`.
-
println!("{}", 8_usize.is_power_of_two());
}
```

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).
[breaking-change]
Most of the changes are cleanup facilitated by straight-forward attribute handling.
This is a minor [breaking-change] for users of `quote_stmt!` (returns `Option<P<Stmt>>` now) and some of the public methods in `Parser` (a few `Vec<Attribute>` arguments/returns were removed).
