Do not error during method probe on `Sized` predicates for types that aren't the method receiver
Fixes#61525
This is safe even though we're skipping an error because we end up confirming the method, which means we're still checking the `Sized` predicate in the end. It just means that we don't emit an erroneous message as below:
```
error: the `query` method cannot be invoked on a trait object
--> src/lib.rs:14:11
|
14 | 1.query::<dyn ToString>("")
| ^^^^^
|
= note: another candidate was found in the following trait, perhaps add a `use` for it:
`use crate::Example;`
```
Also fixes erroneously suggesting the same trait over again, as seen in the `issue-35976.rs` UI test.
Don't rerun the build script for the compiler each time on non-windows platforms
In practice, this doesn't matter very much because the script takes ~no time to run.
But this makes `CARGO_LOG=info` easier to read, and theoretically saves a few milliseconds.
Fix sized check ICE in asm check
Fixes (beta nominated, so doesn't close) #99122
1. Moves a check for unresolved inference variables to _before_ other checks that could possibly ICE. We're not changing behavior here, just doing the same thing earlier in the function.
2. Erases region variables in sized check (which are not resolved at this point) because rustc will also ICE when region vars are passed to a query which does not canonicalize them.
Fix duplicated type annotation suggestion
Before, there was more or less duplicated suggestions to add type hints.
Fix by clearing more generic suggestions when a more specific suggestion
is possible.
This fixes#93506 .
Fix rustdoc help options
Fixes#98976.
Since you're the one who found out about the problem and also provided the solution (thanks for both!):

Support `-A`, `-W`, `-D` and `-F` when running `./x.py clippy`
Resolves#97059
This PR adds support for `-A`, `-W`, `-D` and `-F` when running `./x.py clippy`.
Create fresh lifetime parameters for bare fn trait too
The current code fails to account for the equivalence between `dyn FnMut(&mut u8)` and bare `FnMut(&mut u8)`, and treated them differently.
This PR introduces a special case for `Fn` traits, which are always fully resolved.
Fixes#98616Fixes#98726
This will require a beta-backport, as beta contains that bug.
r? `@petrochenkov`
This extracts the linux-isms into variables, so that the script can be
extended to do PGO on windows. These variables will be overriden in a
few spots, in windows-specific blocks.
When building LLVM/LLD as part of a build that asks LLVM to generate profiles, e.g. when
doing PGO, cmake or clang-cl don't automatically link clang's profiler runtime in,
causing undefined reference errors at link-time.
We do that manually, by adding clang's resource library folder to the library search path:
- for LLVM itself, by extending the linker args that `rustc_llvm`'s build script
uses, to avoid the linker errors when linking `rustc_driver`.
- for LLD, by extending cmake's linker flags during the LLD build step.

Mention similarly named associated type even if it's not clearly in supertrait
Due to query cycle avoidance, we sometimes restrict the candidates in `complain_about_assoc_type_not_found` too much so that we can't detect typo replacements from just supertraits.
This creates a more general note of the existence of a similarly named associated type from _all_ visible traits when possible.
Fixes#55673
Implement `SourceMap::is_span_accessible`
This patch adds `SourceMap::is_span_accessible` and replaces `span_to_snippet(span).is_ok()` and `span_to_snippet(span).is_err()` with it. This removes a `&str` to `String` conversion.
explain doc comments in macros a bit
Open to suggestions on improving this... macro parsing is very foreign to me.
Should we have a structured suggestion to turn them into their regular non-doc comments?

Inline Windows `OsStrExt::encode_wide`
User crates currently produce much more code than necessary because the optimizer fails to make assumptions about this method.
Remove unsupported options in configure.py
I've seen people using `optimize = false` and `full-bootstrap = true` in the past, without knowing
that they're not recommended. Remove `optimize` and a few other options that are always a bad idea,
and document that full-bootstrap is only for testing reproducible builds.
In practice, this doesn't matter very much because the script takes ~no time to run.
But this makes `CARGO_LOG=info` easier to read, and theoretically saves a few milliseconds.
Fix `x build library/std compiler/rustc`
Previously, this was broken because of improper caching:
1. `StepDescription::maybe_run` builds `Compile::Std`, which only built `std` and not `proc_macro`
1. `Std` calls `builder.ensure(StdLink)`
1. `Rustc` calls `ensure(Std)`, which builds all crates, including `proc_macro`
1. `Rustc` calls `ensure(StdLink)`. `ensure` would see that it had already been run and do nothing. <-- bug is here
1. Cargo gives an error that `proc_macro` doesn't exist.
This fixes the caching by adding `crates` to `StdLink`, so it will get rerun if the crates that are built change.
Fixes https://github.com/rust-lang/rust/issues/99129.
Allow using `download-ci-llvm = true` outside the git checkout
`@bjorn3` noticed that this is already allowed today when download-llvm is disabled, but breaks with it enabled:
```
$ ./rust2/x.py build
fatal: not a git repository (or any of the parent directories): .git
thread 'main' panicked at 'command did not execute successfully: "git" "rev-list" "--author=bors@rust-lang.org" "-n1" "--first-parent" "HEAD" "--" "/home/jnelson/rust-lang/rust2/src/llvm-project" "/home/jnelson/rust-lang/rust2/src/bootstrap/download-ci-llvm-stamp" "/home/jnelson/rust-lang/rust2/src/version"
expected success, got: exit status: 128', src/bootstrap/native.rs:134:20
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
```
Support it too for consistency. It's unclear to me when anyone would need to use this, but `@bjorn3`
feels we should support it, and it's not much additional effort to get it working.
Previously, this was broken because of improper caching:
1. `StepDescription::maybe_run` builds `Compile::Std`, which only built `std` and not `proc_macro`
1. `Std` calls `builder.ensure(StdLink)`

1. Cargo gives an error that `proc_macro` doesn't exist.
This fixes the caching by adding `crates` to `StdLink`, so it will get rerun if the crates that are
built change. This also does the same for `RustcLink`; it doesn't matter in practice currently
because nothing uses it except `impl Step for Rustc`, but it will avoid bugs if we start using it in
the future (e.g. to build individual crates for rustfmt).
Fix `download-ci-llvm` NixOS patching for binaries
LLVM tools should also be patched, since they are used in some tests, specially,
- src/test/run-make-fulldeps/cross-lang-lto (llvm-ar)
- src/test/run-make-fulldeps/cross-lang-lto-upstream-rlibs (llvm-ar)
- src/test/run-make-fulldeps/issue-64153 (llvm-objdump)
To be more future proof, we should patch all binaries in `bin`, which is done in this PR.
Group .test-arrow CSS rules and fix rgb/rgba property
Surprisingly, the web browsers were handling the `rgb`/`rgba` typo correctly. At least it now is as expected.
For the rest, it's simply grouping `.test-arrow` rules.

promote placeholder bounds to 'static obligations
In NLL, when we are promoting a bound out from a closure, if we have a requirement that `T: 'a` where `'a` is in a higher universe, we were previously ignoring that, which is totally wrong. We should be promoting those constraints to `'static`, since universes are not expressible across closure boundaries.
Fixes#98693
