Reexported macros docs
Part of #59368 (doesn't fix it, only improve the current situation a bit).
Macros were not correctly handled in reexports and the reexport attributes were not merged with the item either. This PR fixes both.
r? `@notriddle`
Emit JSON output for the building of bootstrap itself
Fixes#107832 .
Main changes are from line 792 onwards. Other changes are due to the flake8 formatter. Let me know if I should not use the formatter.
simplify layout calculations in rawvec
The use of `Layout::array` was introduced in #83706 which lead to a [perf regression](https://github.com/rust-lang/rust/pull/83706#issuecomment-1048377719).
This PR basically reverts that change since rust currently only supports stride == size types, but to be on the safe side it leaves a const-assert there to make sure this gets caught if those assumptions ever change.
Resolve documentation links in rustc and store the results in metadata
This PR implements MCP https://github.com/rust-lang/compiler-team/issues/584.
Doc links are now resolved in rustc and stored into metadata, so rustdoc simply retrieves them through a query (local or extern),
Code that is no longer used is removed, and some code that no longer needs to be public is privatized.
The removed code includes resolver cloning, so this PR fixes https://github.com/rust-lang/rust/issues/83761.

Implement `deferred_projection_equality` for erica solver
Somewhat of a revival of #96912. When relating projections now emit an `AliasEq` obligation instead of attempting to determine equality of projections that may not be as normalized as possible (i.e. because of lazy norm, or just containing inference variables that prevent us from resolving an impl). Only do this when the new solver is enabled
Add ui test for implementation on projection
The error in full can be seen in https://github.com/rust-lang/rust/pull/107263 and is part of why the PR is blocked (it still requires the approval from the team for supporting it).
r? ``@oli-obk``
Add a couple random projection tests for new solver
Self-explanatory, they're just some cases that have been on my mind in the past (especially `tests/ui/traits/new-solver/param-candidate-doesnt-shadow-project.rs`).
Stop at the first `NULL` argument when iterating `argv`
Some C commandline parsers (e.g. GLib and Qt) are replacing already handled arguments in `argv` with `NULL` and move them to the end. That means that `argc` might be bigger than the actual number of non-`NULL` pointers in `argv` at this point.
To handle this we simply stop iterating at the first `NULL` argument.
`argv` is also guaranteed to be `NULL`-terminated so any non-`NULL` arguments after the first `NULL` can safely be ignored.

Mir-Opt for copying enums with large discrepancies
I have been meaning to make this for quite a while, based off of this [hackmd](https://hackmd.io/`@ft4bxUsFT5CEUBmRKYHr7w/rJM8BBPzD).`
I'm not sure where to put this opt now that I've made it, so I'd appreciate suggestions on that!
It's also one long chain of statements, not sure if there's a more friendly format to make it.
r? `@tmiasko`
I would `r` oli but he's on leave so he suggested I `r` tmiasko or wesleywiser.
`slice::sort_unstable` will fall back to heapsort if it repeatedly fails to find
a good pivot. By making the core child update code branchless it is much faster.
On Zen3 sorting 10k `u64` and forcing the sort to pick heapsort, results in:
455us -> 278us

create symlink only for non-windows operating systems
Follow up on #107834
It's my first time using the #cfg attribute. Did I use it correctly?
Thank you!
Allow wasi-libc to initialize its environment variables lazily.
Use `__wasilibc_get_environ()` to read the environment variable list from wasi-libc instead of using `environ`. `environ` is a global variable which effectively requires wasi-libc to initialize the environment variables eagerly, and `__wasilibc_get_environ()` is specifically designed to be an alternative that lets wasi-libc intiailize its environment variables lazily.
This should have the side effect of fixing at least some of the cases of #107635.
avoid duplicating the RUSTC_LOG env var name
We also have the env var name here:
c40919b7a7/compiler/rustc_driver_impl/src/lib.rs (L1247-L1251)
Redundantly having this name twice doesn't seem great. Looks like `rustc_log::init_rustc_env_logger` is dead code anyway.
