In accordance with RFC 3771.
I also added a stub doc page for the target and renamed the
windows-gnullvm page for consistency.

Update mdbook to 0.4.48
This brings in several updates. Two significant ones are to halve the search index size, and the other introduces major changes to footnote rendering.

remove `feature(inline_const_pat)`
Summarizing https://rust-lang.zulipchat.com/#narrow/channel/144729-t-types/topic/remove.20feature.28inline_const_pat.29.20and.20shared.20borrowck.
With https://github.com/rust-lang/types-team/issues/129 we will start to borrowck items together with their typeck parent. This is necessary to correctly support opaque types, blocking the new solver and TAIT/ATPIT stabilization with the old one. This means that we cannot really support `inline_const_pat` as they are implemented right now:
- we want to typeck inline consts together with their parent body to allow inference to flow both ways and to allow the const to refer to local regions of its parent.This means we also need to borrowck the inline const together with its parent as that's necessary to properly support opaque types
- we want the inline const pattern to participate in exhaustiveness checking
- to participate in exhaustiveness checking we need to evaluate it, which requires borrowck, which now relies on borrowck of the typeck root, which ends up checking exhaustiveness again. **This is a query cycle**.
There are 4 possible ways to handle this:
- stop typechecking inline const patterns together with their parent
- causes inline const patterns to be different than inline const exprs
- prevents bidirectional inference, we need to either fail to compile `if let const { 1 } = 1u32` or `if let const { 1u32 } = 1`
- region inference for inline consts will be harder, it feels non-trivial to support inline consts referencing local regions from the parent fn
- inline consts no longer participate in exhaustiveness checking. Treat them like `pat if pat == const { .. }` instead. We then only evaluate them after borrowck
- difference between `const { 1 }` and `const FOO: usize = 1; match x { FOO => () }`. This is confusing
- do they carry their weight if they are now just equivalent to using an if-guard
- delay exhaustiveness checking until after borrowck
- should be possible in theory, but is a quite involved change and may have some unexpected challenges
- remove this feature for now
I believe we should either delay exhaustiveness checking or remove the feature entirely. As moving exhaustiveness checking to after borrow checking is quite complex I think the right course of action is to fully remove the feature for now and to add it again once/if we've got that implementation figured out.
`const { .. }`-expressions remain stable. These seem to have been the main motivation for https://github.com/rust-lang/rfcs/issues/2920.

Introduce `-Zembed-metadata` to allow omitting full metadata from rlibs and dylibs
This is a continuation of https://github.com/rust-lang/rust/pull/120855 (I was mentored by `@bjorn3` to move it forward). Most of the original code was written by bjorn3, I tried to clean it up a bit and add some documentation and tests.
This PR introduces a new unstable compiler flag called `-Zembed-metadata=[no|yes]`, with the default being `yes` (see https://github.com/rust-lang/rust/issues/57076 for context). When set to `no`, rustc will only store a small metadata stub inside rlibs/dylibs instead of the full metadata, to keep their size smaller. It should be used in combination with `--emit=metadata`, so that the users of such a compiled library can still read the metadata from the corresponding `.rmeta` file. [This comment](https://github.com/rust-lang/rust/pull/120855#issuecomment-1937018169) shows an example of binary/artifact size wins that can be achieved using this approach.
Contrary to https://github.com/rust-lang/rust/pull/120855, this PR only introduces the new flag, along with a couple of run-make tests and documentation, but does not yet use it in bootstrap to actually compile rustc. I plan to do that as a follow-up step (along with integration in Cargo, which should ideally just always pass this flag to reduce the size of target directories).
Fixes https://github.com/rust-lang/rust/issues/23366
Closes https://github.com/rust-lang/rust/issues/29511

Update target maintainers for thumb targets to reflect new REWG Arm team name
Closes #139027
The name of the team responsible for these targets has changed as the team was merged with other Arm-related teams (see https://github.com/rust-embedded/wg/pull/818). The link gives an up-to-date list of github usernames that can be pinged, whereas the old email address is not very actively maintained or tracked.

This removes the `--enable-per-target-ignores` and enables it
unconditionally.
|
|
|
|
This renames `--runtool` and `--runtool-arg` to `--test-runtool` and
`--test-runtool-arg` to maintain consistency with other `--test-*`
arguments.

Improve `xcrun` error handling
The compiler invokes `xcrun` on macOS when linking Apple targets, to find the Xcode SDK which contain all the necessary linker stubs. The error messages that `xcrun` outputs aren't always that great though, so this PR tries to improve that by providing extra context when an error occurs.
Fixes https://github.com/rust-lang/rust/issues/56829.
Fixes https://github.com/rust-lang/rust/issues/84534.
Part of https://github.com/rust-lang/rust/issues/129432.
See also the alternative https://github.com/rust-lang/rust/pull/131433.
Tested on:
- `x86_64-apple-darwin`, MacBook Pro running Mac OS X 10.12.6
- With no tooling installed
- With Xcode 9.2
- With Xcode 9.2 Commandline Tools
- `aarch64-apple-darwin`, MacBook M2 Pro running macOS 14.7.4
- With Xcode 13.4.1

Un-bury chapters from the chapter list in rustc book
This PR moves the "Platform Support" section to the bottom of rustc chapter book, as to un-burry chapters from the chapter list, which where hidden by the wall of targets.

Add mipsel maintainer

I've intentionally used slightly vague language ("roughly"), as we don't
want to guarantee the exact invocation of `xcrun`, just hint that it's
close to that.

Add target maintainer information for powerpc64-unknown-linux-musl
We intend to fix the outstanding issues on the target and eventually promote it to tier 2. We have the capacity to maintain this target in the future and already perform regular builds of rustc for this target.
Currently, all host tools except miri build fine, but I have a patch for libffi-sys to make miri also compile fine for this target that is [pending review](https://github.com/tov/libffi-rs/pull/100).
While at it, add an option for the musl root for this target.
I also added a kernel version requirement, which is rather arbitrarily chosen, but it matches our tier 2 powerpc64le-unknown-linux-musl target so I think it is a good fit.

Rework `--print` options documentation
This PR reworks the `--print` options documentation, by making it more like codegen options with a dedicated page.
I also added some examples and split some paragraph into multiple paragraph since we now have more place.
